When putting the stirrup 30 into the temporary storage channel 60, the second toggle mechanism 12 can firstly lift the bottom of the stirrup 30, so that the stirrup 30 is ensured to be placed stably in advance, and then the first toggle mechanism 11 laterally contacts the side surface of the stirrup 30, so that the stirrup 30 can be ensured to be stably placed. In particular, the first toggle mechanism 11 and the second toggle mechanism 12 are arranged diagonally. So stirrup 30 can be directly with the mode of parallel promotion just can be fast, firm card put first toggle mechanism 11 and second toggle mechanism 12 on, reduce stirrup 30 and put the degree of difficulty to when first toggle mechanism 11 and second toggle mechanism 12 synchronous motion, the stirring atress that stirrup 30 received is even. Of course, in other embodiments, the first toggle mechanism 11 and the second toggle mechanism 12 may also be arranged horizontally side by side, and other structural arrangements are also within the protection scheme of the present application.

When the first toggle mechanism 11 and the second toggle mechanism 12 are arranged diagonally, the stirrup 30 may be placed unstably and toppled, which affects the normal welding of the subsequent stirrup 30 and the longitudinal bar 50. Further, in some embodiments, the centralized temporary storage device 10 further includes a second bracket 16 arranged side by side with a space from the first bracket 15, and a support plate 17 disposed on the second bracket 16, wherein the support plate 17 is used for contacting with the bottom of the stirrup 30. Specifically, the second bracket 16 is disposed below the first toggle mechanism 11, and at this time, the second bracket 16, the first bracket 15 and the first toggle mechanism 11 form a triangular structure arrangement in a vertical plane, so that the support plate 17 can form a longitudinal support for another corner portion of the stirrup 30, that is, the support plate 17 can form a triangular limit structure with the most stable structure with the first fixture block 112 and the second fixture block 122, and the stable swing of the stirrup 30 can be ensured to the greatest extent.

Because the first and second blocks 112 and 122 are driven by the first and second dialing members 111 and 121 to drive the corresponding stirrups 30 to move and slide, in order to reduce the moving resistance, frictional wear and noise, the contact part of the support plate 17 and the stirrups 30 is designed to be an arc surface or a roller (made of rubber or other materials).

In actual production and processing, for structures such as beams, columns and stairs with different sizes, the sizes of the reinforcement cages required to be used are different, and the direct representation is that the length, width, height and shape of the stirrups 30 are different. To improve the versatility of the centralized temporary storage device 10 for different sizes and shapes of stirrups 30, in some embodiments, the centralized temporary storage device 10 further comprises a first displacement mechanism disposed at the bottom of the carriage 13, the first bracket 15 is connected with the first displacement mechanism, and the first displacement mechanism is used for driving the first bracket 15 to approach or depart from the second bracket 16; and/or the centralized temporary storage device 10 further comprises a second moving mechanism arranged at the bottom of the carrying frame 13, the second bracket 16 is connected with the second shifting mechanism, and the second shifting mechanism is used for driving the second bracket 16 to approach or depart from the first bracket 15. Preferably, the first shifting mechanism and the second shifting mechanism are arranged simultaneously, and can drive the first bracket 15 and the second bracket 16 to move towards each other or away from each other independently or simultaneously according to actual needs, so that the first toggle mechanism 11 and the second toggle mechanism 12 flexibly form different intervals, that is, different sizes of temporary storage channels 60 are obtained, and therefore the device can be suitable for temporarily storing and placing stirrups 30 with different sizes and structures.

Alternatively, the first displacement mechanism and the second displacement mechanism are mechanisms capable of outputting reciprocating linear power, and may be, for example and without limitation, a motor + lead screw slider mechanism, a cylinder + scissor fork mechanism, and the like.

It is understood that the stirrups 30 can be L-shaped, T-shaped, circular, triangular, etc. The concrete can be selected according to the actual needs of the person skilled in the art.

Fig. 5 shows a schematic structural view of the centralized temporary storage device 10 for placing the L-shaped stirrup 30.

In some embodiments, the first toggle mechanism 11 further includes a first bracket, a first driving source disposed on the first bracket, and a first driving wheel set rotatably disposed on the first bracket and in driving connection with the first driving source. The first bracket is fixedly connected to the suspension bracket 14 so as to suspend the first driving source, the first driving wheel set, and the first dial 111. Similarly, the second toggle mechanism 12 further includes a second support, a second driving source disposed on the second support, and a second driving wheel set rotatably disposed on the second support and in driving connection with the second driving source. The second bracket is fixedly connected to the first bracket 15, so that the first bracket 15 can support and fix the second driving source, the second driving wheel set and the second transfer member 121.

In addition, the first driving wheel set is used for driving the first pulling piece 111 to reciprocate, and the second driving wheel set is used for driving the second pulling piece 121 to reciprocate. When the first driving wheel set is driven to rotate forwards or reversely by the first driving source output power and the second driving wheel set is driven to rotate forwards or reversely by the second driving source output power (the first driving wheel set and the second driving wheel set rotate in the same direction), the first driving wheel set can drive the first poking and sending piece 111 and the second driving wheel set can drive the second poking and sending piece 121 to rotate along the reciprocating straight line between the two ports of the temporary storage channel 60, the purpose of temporarily storing and placing the stirrups 30 firstly is realized, and then the stirrups 30 are sent out one by one for welding.

Preferably, in some embodiments, the first driving source is a first motor, the first driving wheel set is a first chain wheel set, and the first conveying member 111 is a first chain that is engaged and sleeved on the first chain wheel set. The second driving source is a second motor, the second driving wheel set is a second chain wheel set, the second poking and conveying piece 121 is a second chain, and the second chain is meshed and sleeved on the second chain wheel set. The chain wheel set is meshed with the chain for transmission, so that power transmission is more stable, the weight bearing capacity of the stirrup 30 is stronger, and the service life can be ensured; and more importantly, because the chain adopts a plurality of chain links to rotate through the round pin axle and constitutes, and the length of each chain link is the same, therefore through install first fixture block 112 and second fixture block 122 on each chain link, then guarantee more easily that the interval between two adjacent first fixture blocks 112 and two adjacent second fixture blocks 122 equals, and then guarantee that the interval of putting of stirrup 30 equals, guarantee follow-up each stirrup 30 and the welding forming quality of indulging muscle 50.

It should be noted that, as an alternative to the above embodiments, in other embodiments, the sprocket set may also adopt a gear set, and the chain is replaced by a rack, so that when the motor drives the gear set to rotate in the forward direction or the reverse direction, the rack can be driven to move back and forth, thereby achieving the purpose of temporarily storing and placing the stirrups 30, and then sending out the stirrups 30 one by one for welding.

In order to ensure that the stirrup 30 is firmly placed, in some embodiments, the first block 112 has a first slot, the second block 122 has a second slot opposite to the first slot, and the widths of the first slot and the second slot both increase from the bottom of the slot to the top of the slot. The design of the first clamping groove and the second clamping groove with the gradually changed groove width sizes can not only ensure that the stirrup 30 can be placed reliably through the freedom degree of the better limiting stirrup 30 in a clamping mode, but also can be better adapted to the stirrup 30 with different sizes, and is more favorable for improving the universality of the first shifting mechanism 11 and the second shifting mechanism 12. It can be understood that the first and second locking grooves may be V-shaped grooves, U-shaped grooves, trapezoidal grooves, or the like, and may be specifically selected according to actual needs.

Along with the conveying effect that piece 111 and the second piece 121 were dialled to first dialling send, the stirrup 30 in each group's first draw-in groove and second draw-in groove all can be removed the terminal surface department that carries frame 13 one by one along leading smooth sleeve pipe 21 horizontal slip, and then breaks away from first draw-in groove and second draw-in groove and falls to indulging on the muscle 50, weld clamping device will indulge muscle 50 and stirrup 30 centre gripping and paste tightly immediately, welder welds the laminating position, can accomplish to indulge muscle 50 and stirrup 30 and be connected concretely as an organic whole.

Further, in some embodiments, the rotation axis of the first dial 111 is disposed perpendicular to a horizontal plane, the rotation axis of the second dial 121 is disposed parallel to the horizontal plane, and the rotation axis of the first dial 111 and the rotation axis of the second dial 121 are perpendicular to each other. At this moment, the notch of second draw-in groove can set up towards the top, and the notch of first draw-in groove sets up towards the right-hand side, and the top one corner of stirrup 30 can be blocked to the second draw-in groove, and first draw-in groove then can block the side one corner of stirrup 30, realizes clamping fixed more firm stirrup 30, can effectively avoid stirrup 30 to take place to heel towards adjacent both sides stirrup 30, influences follow-up normal welding process.

As described in the above solution, the stirrups 30 located in the temporary storage channel 60 are uniformly spaced, and need to be sent out one by one according to a predetermined beat when being welded and fixed with the longitudinal reinforcement 50, at this time, in order to control the sending-out rate of each stirrup 30 and make the sending-out rate of the subsequent stirrup 30 match the welding time of the previous stirrup 30, in some embodiments, the centralized temporary storage device 10 further includes a start-stop switch and a controller, the start-stop switch is electrically connected to the controller, and the controller is electrically connected to the first drive source and the second drive source, respectively. When pressing and opening the stop switch in proper order, the controller alright receive one and send out the signal, and the controller and then output command is first driving source and the certain angle of second driving source synchronous rotation this moment, and this certain angle of rotation corresponds first group and send piece 111 and second group and send a 121 removal distance, and the removal distance equals two adjacent stirrup 30's interval. So far, alright open the switch through not operating in proper order, just can send out the purpose of a stirrup 30, make every stirrup 30 all possess sufficient time and indulge muscle 50 welded fastening, each stirrup 30 can not take place mutual interference, can guarantee normal processing of steel reinforcement cage and shaping quality to the at utmost.

It should be noted that triggering the start-stop switch may be manually performed by a worker, or may be automatically performed by a machine. When manual operation of workers is adopted, the workers can press by hands or tread by feet, and a better treading mode is adopted, so that the labor is saved, and the operation is more convenient.

With continued reference to fig. 1, fig. 6 and fig. 7, in some embodiments, the auxiliary positioning device 20 further includes a positioning actuator connected to the slide guiding sleeve 21 and configured to support the slide guiding sleeve 21 to cling to the inner wall of the corner of the stirrup 30. Specifically, the positioning actuator includes a fixing frame 22, a displacement assembly 23 disposed on the fixing frame 22, and a pipe clamp 24 connected to the displacement assembly 23, and the sliding guide sleeve 21 is connected to the pipe clamp 24. The fixed frame 22 can bear the fixed displacement assembly 23 and bear the weight of the longitudinal ribs 50 during work, so that the structure is stable; the shifting assembly 23 can clamp the stable sliding guide sleeve 21 through the pipe clamp 24, and the sliding guide sleeve 21 can be quickly and accurately positioned and attached to the inner wall of the corner of the stirrup 30 through accurate movement in a space, so that reliable guarantee is provided for positioning and matching of the follow-up longitudinal rib 50 and the stirrup 30.

It should be noted that, for the sake of understanding, in the embodiments described below, the longitudinal ribs 50 are all referred to as longitudinal rib main ribs, and the longitudinal rib main ribs are arranged inside the corners of the stirrups 30. For the longitudinal rib auxiliary rib, the stirrup 30 can be positioned to the inner side of the middle of each side by adopting the same positioning actuator, and the working principle and method are the same as the working mode of the longitudinal rib main rib, which is not described herein again.

In operation, after the slide guiding sleeve 21 is positioned to the inner side of the corner of the stirrup 30, the longitudinal rib 50 can be inserted into the lumen of the slide guiding sleeve 21 by the rib threading mechanism. In order to improve the versatility of the sliding guide sleeve 21, so as to accommodate the longitudinal ribs 50 with different diameters or the longitudinal ribs 50 with machining dimension errors, in some embodiments, the inner diameter of the sliding guide sleeve 21 is larger than the maximum diameter of the longitudinal ribs 50. It should be understood that the maximum diameter of the longitudinal rib 50 may be the diameter of the thickest part of a single longitudinal rib 50 having a machining dimension error, or may be the longitudinal rib 50 having the largest diameter among a series of longitudinal ribs 50 having different dimensions.

With reference to fig. 7, the slide guiding sleeve 21 is provided with an inlet end 211, and in order to facilitate the operation of threading the longitudinal rib 50, the inlet end 211 is provided with an introducing structure 212, and the introducing structure 212 is used for facilitating the insertion of the longitudinal rib 50 into the slide guiding sleeve 21. Specifically, the guiding structure 212 is a conical cylinder, a small-diameter end of the conical cylinder is aligned and connected to the inlet end 211 of the sliding guide sleeve 21, and a large-diameter end faces the direction of the rib penetrating mechanism. The heavy-calibre end is greater than the diameter of indulging muscle 50, allows to indulge the counterpoint before muscle 50 poling and can have certain precision error, reduces the poling degree of difficulty, and the skew wall of awl barrel possesses the smooth effect of leading to indulging muscle 50 simultaneously, makes to indulge muscle 50 and inserts more easily in leading smooth sleeve pipe 21. Of course, in other embodiments, the import structure 212 may also be other structures and devices in the prior art, which are not described herein.

As described above, since the inner diameter of the slide guiding sleeve 21 is larger than the diameter of the longitudinal rib 50, the longitudinal rib 50 forms an annular fitting gap after penetrating into the slide guiding sleeve 21. The stirrup 30 is sleeved outside the slide-guiding sleeve 21, so that the distance between the stirrup 30 and the longitudinal rib 50 is equal to the sum of the thickness of a single edge of the annular fitting gap and the wall thickness of the slide-guiding sleeve 21. However, the larger the distance value is, the more difficult the subsequent longitudinal rib 50 and the stirrup 30 are to be clamped tightly, that is, the more difficult the welding process between the longitudinal rib 50 and the stirrup 30 is. Therefore, after the longitudinal rib 50 is inserted into the sliding guide sleeve 21, the rib threading mechanism needs to expand and move outward along the radial direction, that is, the longitudinal rib 50 is driven to expand and move toward the outer sides of the four corners of the stirrup 30, so that the longitudinal rib 50 can be tightly attached to the inner wall portion of the sliding guide sleeve 21 close to the corners of the stirrup 30. In this way, the longitudinal ribs 50 can be as close as possible to the stirrups 30, which is beneficial for subsequent clamping, welding or binding operations.

With continued reference to fig. 6 and 7, in any of the above embodiments, the fixing frame 22 is formed as a circular frame plate structure, preferably a regular octagon. In some embodiments, the displacement assemblies 23 and the pipe clamps 24 are at least two and are connected in a one-to-one correspondence, and at least two displacement assemblies 23 are circumferentially distributed on the fixing frame 22. In particular, the displacement assemblies 23 and the pipe clamps 24 are four in number and are arranged along a cross-shaped configuration on the same side of the fixing frame 22 facing the concentration buffer 10. Each pipe clamp 24 is used for clamping one sliding guide sleeve 21, a longitudinal rib 50 is respectively inserted into each sliding guide sleeve 21, and each longitudinal rib 50 is correspondingly positioned and clings to one corner inner wall of the stirrup 30. Four aversion subassemblies 23 can be synchronous collaborative operation this moment, accomplish the location operation of four vertical bars 50 (indulge muscle main muscle) in the steel reinforcement cage simultaneously, improve steel reinforcement cage production efficiency greatly. Of course, when the stirrups 30 have other shapes and the longitudinal ribs 50 have other numbers, the positioning actuators may have other numbers correspondingly, and the invention is also within the scope of the present application.

In some embodiments, the displacement assembly 23 includes a first moving unit 231 and a second moving unit 232 connected to the first moving unit 231, the first moving unit 231 is used for outputting a driving force in one of a horizontal direction or a vertical direction, the second moving unit 232 is used for outputting a driving force in the other of the horizontal direction or the vertical direction, and the pipe clamp 24 is connected to the second moving unit 232; the first mobile unit 231 and the second mobile unit 232 can act sequentially or synchronously. Particularly, so successively or synchronous movement is carried out with the help of first mobile unit 231 and second mobile unit 232, can drive and lead smooth sleeve pipe 21 and fix a position fast accurate and paste and tightly to stirrup 30 corner inboard, and can walk according to multiple removal trails such as straight line, pitch arc at the removal in-process, do benefit to and lead smooth sleeve pipe 21 and save to remove consuming time, do benefit to simultaneously and keep away the barrier, improve and lead smooth sleeve pipe 21 positioning reliability.

It should be noted that, since the four shifting units 23 are arranged in a cross shape in the preferred embodiment, when the first moving unit 231 or the second moving unit 232 with the same property are located at different orientations, there is a difference in the output power direction. For example, in the shift assembly 23 in the vertical direction, the first moving unit 231 may output a driving force in the horizontal direction, and at this time, the second moving unit 232 may output a driving force in the vertical direction. However, in the horizontal direction of the displacement assembly 23, which is also the first moving unit 231, the driving force in the vertical direction is outputted, and the moving force in the horizontal direction is outputted by the second moving unit 232.

It should be noted that, since the projection of the stirrup 30 in the centralized temporary storage device 10 along the axial direction is located in the middle of the hollow cavity formed by the fixed frame 22, no matter whether the second moving unit 232 is located in the vertical direction or the horizontal direction, only the sliding guide sleeve 21 can be driven to move close to or away from the stirrup 30.

In some embodiments, the first moving unit 231 includes a first guide rail 231a disposed on the fixing frame 22, a first driving member 231b disposed on the fixing frame 22, a first transmission pair 231c connected to the first driving member 231b, and a sliding seat 231d slidably disposed on the first guide rail 231a and connected to the first transmission pair 231c, and the second moving unit 232 is disposed on the sliding seat 231 d. Thus, the second moving unit 232 can quickly find the corner of the stirrup 30 with the slide guiding sleeve 21 under the driving of the first moving unit 231, and the positioning efficiency is ensured. And the second moving unit 232 can slide back and forth in the vertical direction and the horizontal direction, so that the slide guide sleeve 21 has the capability of being suitable for stirrups 30 with different shapes.

Specifically, the first driving member 231b is a motor, and the first transmission pair 231c is a lead screw nut pair. The screw rod is connected with a power shaft of the motor, and when the motor drives the screw rod to rotate, the nut can slide along the screw rod in a reciprocating mode, so that the purpose of driving the second moving unit 232 to slide in a reciprocating mode is achieved. The power transmission is stable, and the structure is simple. Of course, in other embodiments, the specific structure of the first moving unit 231 may also adopt other driving structures in the prior art, and may be selected according to actual needs.

Still referring to fig. 7, in some embodiments, the second moving unit 232 includes a second driving member 232a and a second guiding rail 232b respectively disposed on the sliding base 231d, a driving wheel 232c connected to the second driving member 232a, and a telescopic arm 232d drivingly connected to the driving wheel 232c, the telescopic arm 232d is slidably disposed on the second guiding rail 232b, and the telescopic arm 232d is connected to the pipe clamp 24. So, it is rotatory through second driving piece 232a drive wheel 232c, and drive wheel 232c can stretch out or withdraw with the help of frictional force drive flexible arm 232d to on the corner inner wall that leads smooth sleeve pipe 21 final positioning and hug closely stirrup 30 is driven by flexible arm 232d, for follow-up muscle 50 poling and stirrup 30 and the muscle 50 location of indulging provide reliable basis.

Specifically, the wheel face of the driving wheel 232c is provided with a first tooth structure, the telescopic arm 232d is provided with a second tooth structure, and the first tooth structure is in meshing transmission fit with the second tooth structure. It can be understood that, this moment, drive wheel 232c constitutes the rack and pinion transmission with flexible arm 232d and is vice, with the help of the tooth meshing transmission, can guarantee that power transmission is steady, and is strong to leading smooth sleeve 21 and indulging the load bearing capacity of muscle 50, ensures that the displacement is reliable and accurate. Of course, in other embodiments, the specific structure of the second moving unit 232 may also adopt other driving structures in the prior art, such as a scissors mechanism, a lead screw slider mechanism, and the like, which can be selected according to actual needs.

In some embodiments, the telescopic arm 232d is provided with a mounting hole, the slide guide sleeve 21 is inserted through the mounting hole, the pipe clamp 24 includes a first hoop plate set 241 and a second hoop plate set 242, the first hoop plate set 241 and the second hoop plate set 242 are hooped on the slide guide sleeve 21 and are respectively arranged on two opposite sides of the telescopic arm 232d, and the first hoop plate set 241 and the second hoop plate set 242 are abutted to the telescopic arm 232 d. In actual operation, the sliding guide sleeve 21 and the longitudinal rib 50 are both long and made of metal materials, so that the total weight of the sliding guide sleeve and the longitudinal rib is large after the sliding guide sleeve and the longitudinal rib are sleeved with each other. Whether the sliding guide sleeve 21 can be clamped stably or not will greatly influence the positioning accuracy and welding quality of the subsequent longitudinal bars 50 and the stirrups 30. Therefore, in the application, reliable clamping of the sliding guide sleeve 21 is realized by means of the cooperation of the telescopic arm 232d, the first hoop plate set 241 and the second hoop plate set 242, specifically, the contact support area of the sliding guide sleeve 21 can be increased by the first hoop plate set 241 and the second hoop plate set 242, and the first hoop plate set 241 and the second hoop plate set 242 are laterally abutted against the telescopic arm 232d, and the generated abutting force can be uniformly distributed on the circumferential contact area of the sliding guide sleeve 21, so that the radial support capability of the sliding guide sleeve 21 and the longitudinal rib 50 can be improved, and the occurrence of fracture caused by overlarge bending moment or excessive stress concentration at the telescopic arm 232d can be effectively avoided.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
