A cable reel according to an embodiment of the present invention is described below with reference to fig. 1 to 4.

According to an embodiment of the first aspect of the present invention, a cable reel apparatus includes: a support structure 100, a drive device 300, a plurality of cable reels 200.

A support structure 100 including a main support frame 110 and a rotation support shaft 120 disposed on the main support frame 110;

a plurality of cable reels 200 rotatably disposed on the rotation support shaft 120;

and a driving device 300 having a plurality of driving portions capable of rotating independently, wherein the plurality of driving portions are arranged in one-to-one correspondence with the plurality of cable reels 300 and are respectively used for driving the plurality of cable reels 200 to rotate.

Referring to fig. 1 to 2, the main support frame 110 serves as a mounting and support base, and the rotation support shaft 120 is directly mounted on the main support frame 110, and maintains a sufficient height of the rotation support shaft 120 to provide a space for subsequent installation of the cable drum 300 and the driving device 300. The rotary bearings of the plurality of cable drums 200 are inserted into the rotary support shaft 120, so that the cable drums 200 can rotate around the rotary support shaft 120. Typically, the plurality of cable reels 200 are spaced apart at equal intervals to ensure that they do not interfere with each other during rotation.

The driving device 300 is disposed on the base 111 of the main supporting frame 110, and each driving portion is disposed corresponding to one cable reel 200, so as to ensure that the corresponding cable reel 200 can be driven to rotate when the driving portion rotates. The plurality of driving portions are independently provided, so that independent driving can be realized when one or more cable reels 200 need to be driven.

According to the cable reel device of the embodiment of the present invention, the plurality of cable reels 200 are disposed on the rotating support shaft 120, so that the cable reel device of the embodiment of the present invention has a foundation capable of reeling and unreeling a plurality of cables, and further, the plurality of cable reels 200 can be driven by the driving device 300, thereby achieving the purpose of reeling and unreeling a plurality of cables. Meanwhile, each driving part in the driving device 300 can rotate independently, so that each cable reel 200 can be driven independently, the cable winding and unwinding device provided by the embodiment of the invention can simultaneously wind and unwind a plurality of cables, and can wind and unwind a single cable or any number of cables, and the application range of the cable winding and unwinding device provided by the embodiment of the invention is widened. Compared with the traditional cable winding and unwinding device, the cable winding and unwinding device provided by the embodiment of the invention has the capability of simultaneously winding and unwinding a plurality of cables, is simple in overall structure, and is suitable for industrial popularization.

In some embodiments of the present invention, referring to fig. 1, the above-described cable reel apparatus further includes a plurality of bushings 130 disposed on the rotation support shaft 120, the plurality of bushings 130 being used to separate and restrain the plurality of cable reels 200. The shaft sleeve 130 can effectively separate the cable reel 200, thereby avoiding the situation that the cable reel 200 may contact after long-time rotation, and meanwhile, because the driving device 300 is difficult to move after being fixed, the relative position relationship between the cable reel 200 and the driving part of the driving device 300 can be kept fixed after being limited by the shaft sleeve 130.

In some embodiments of the present invention, referring to fig. 1 and 2, the driving device 300 includes: a drive motor 310 and a plurality of drive assemblies 320. The axis of the output shaft of the driving motor 310 is parallel to the axis of the rotation supporting shaft 120; the plurality of driving assemblies 320 are sequentially connected along the axial direction of the output shaft, each driving assembly 320 has a driving portion, the driving assembly 320 closest to the output shaft is connected with the output shaft, and the plurality of driving assemblies 320 and the plurality of cable reels 200 are arranged in one-to-one correspondence. The driving motor 310 drives the driving component 320 directly connected to the driving motor through the output shaft to move, and then the driving components 320 can be sequentially driven to move, so that all driving parts rotate, and all cable reels 200 are driven to reel and reel cables. By changing the forward and reverse rotation state of the driving motor 310, the switching of the cable winding and unwinding can be realized. In addition, when the axis of the output shaft of the driving motor 310 is not parallel to the axis of the rotation supporting shaft 120, the adjustment may be implemented by worm and gear transmission, or the like, so as to implement the transmission of the driving motor 310 to the plurality of driving assemblies 320.

In some embodiments of the present invention, referring to fig. 1 and 4, each of the driving assemblies 320 includes: drive support 321, drive shaft 322, drive wheel 323, first clutch 324. The driving shaft 322 is rotatably arranged on the driving support 321; the driving wheel 323 is rotatably arranged on the driving shaft 322 and is used for driving the cable drum 200 to rotate; the first clutch 324 is disposed on one side of the driving wheel 323, and has a driven end fixedly connected to the driving wheel 323 and a driven end fixedly connected to the driving shaft 322. The driving bracket 321 rotatably supports the driving shaft 322 through a bearing seat, and the driving shaft 322 can be rotated after the driving motor 310 is started. The drive wheel 323 is coupled to the drive shaft 322 via a bearing and is rotatable about the drive shaft 322. The driving end of the first clutch 324 is fixed to the driving shaft 322, and therefore the driving shaft 322 rotates along with the driving shaft, so that when the first clutch 324 is in a closed state, the driving end arranged on one side of the driving wheel 323 can be driven to rotate synchronously, and the driving wheel 323 is driven to rotate, and the cable drum 200 is driven to rotate by the driving wheel 323. When the first clutch 324 is not closed, the driving wheel 323 and the driving shaft 322 are rotationally connected, so that the driving shaft 322 does not drive the driving wheel 323 to rotate synchronously, and the cable drum 200 corresponding to the driving wheel 323 stops rotating. With the structure, when a certain cable reel 200 needs to be used, only the first clutch 324 in the corresponding driving assembly 320 needs to be closed, and when the cable reel does not need to be used, only the first clutch 324 needs to be separated.

In some embodiments of the present invention, referring to fig. 4, the driving assembly 320 further includes a second clutch 325 disposed at the other side of the driving wheel 323, wherein a driven end of the second clutch 325 is fixedly connected to the driving wheel 323 and a driving end is fixedly connected to the driving support 321. Although the first clutch 324 is disengaged and does not rotate the driving wheel 323, the driving wheel 323 may rotate slightly due to the small friction between the driving wheel 323 and the driving shaft 322. At this time, the rotation of the driving wheel 323 can be effectively prevented by the second clutch 325. The driven end of the second clutch 325 is fixed to the driving wheel 323 at a side away from the first clutch 324, and the driving end is directly fixed to the driving support 321, so that when the second clutch 325 is closed, the driven end is directly kept in a non-movable state due to the connection with the driving end, and at this time, the driving wheel 323 fixedly connected to the driven end cannot rotate, so that the driving wheel 323 is braked, and the cable drum 200 can be braked by the driving wheel 323.

In some embodiments of the present invention, the driving assembly 320 further includes a brake assist member disposed on the driving support 321, and the driving end of the second clutch 325 is fixedly coupled to the brake assist member. To facilitate installation of the second clutch 325, a brake assist member is provided on the drive support 321 so that the drive end of the second clutch 325 can more easily find a fixed mounting location. Referring to fig. 4, the brake assist feature may be a flange plate or the like to provide a relatively flat mounting surface for the second clutch 325. In some embodiments of the present invention, the first clutch 324 and the second clutch 325 are under interlock control, and only one of the two clutches is in a closed state, so as to avoid simultaneous driving and braking of the driving wheel 323.

In some embodiments of the present invention, referring to fig. 1, the drive device 300 further comprises a coupling 400, the coupling 400 being used to connect the drive shafts 322 of two adjacent drive assemblies 320. The plurality of driving assemblies 320 may theoretically use one driving shaft 322 penetrating therethrough, so that the plurality of driving assemblies 320 have driving force at the same time, and then the control of whether to drive the cable drum 200 may be realized through the first clutch 324 and the second clutch 325. However, the use of one drive shaft 322 is disadvantageous for the installation of the entire drive device 300 because it requires the installation of the entire drive device; in this case, a plurality of driving shafts 322 may be used, one driving shaft 322 may be used in each driving assembly 320, and then the plurality of driving shafts 322 may be connected in series by using the coupling 400. When the driving device 300 needs to be assembled, the driving components 320 can be installed one by one, so that the installation difficulty is reduced, the difficulty of maintenance after the installation is reduced, and in addition, the transportation is facilitated.

In some embodiments of the present invention, referring to fig. 1, 3, 4, each cable drum 200 includes: reel 210, drive wheel 220. The reel 210 is rotatably disposed on the rotation supporting shaft 120; the driving wheel 220 is provided on the reel 210, and a rim thereof protrudes from the reel 210 and abuts against a rim of the driving wheel 323. After the edge of the driving wheel 220 protrudes out of the reel 210, the driving wheel 220 can be driven to move by directly utilizing the friction force of the driving wheel 323 through abutting against the edge of the driving wheel 323, and then the reel 210 is driven to rotate synchronously.

In some embodiments of the present invention, the driving wheel 323 may also be connected to the driving wheel 220 via a belt or other transmission component, so as to drive the driving wheel 220 to rotate. In some embodiments of the present invention, the driving wheel 323 may not use friction to drive the driving wheel 220, and a gear structure may be adopted to engage the driving wheel 323 and the driving wheel 220, so as to achieve transmission.

In some embodiments of the present invention, the driving motor 310 employs a reduction motor. Compared with the common alternating current motor, the speed reducing motor has better operation effect.

In some embodiments of the present invention, main support frame 110 comprises: a base 111 and a vertical bearing seat 112. The base 111 is used for placing the driving device 300; the vertical bearing housing 112 is used to mount the rotating support shaft 120. The base 111 can provide a mounting base for better fixing the driving device 300. The vertical bearing seat 112 can support the rotating support shaft 120, and provide a support base for the plurality of cable reels 200.

A control system for a cable reel apparatus according to an embodiment of a second aspect of the present invention, for controlling the above-described cable reel apparatus, includes: torque sensor 510, controller 520, display control unit 530.

A torque sensor 510 for detecting a driving torque of the driving device 300 for driving the plurality of cable drums 200 to rotate;

the controller 520 is electrically connected with the torque sensor 510 and is used for adjusting the state of the driving device 300 for driving the plurality of cable drums 200 according to the driving torque;

the display control unit 530 is connected to the controller 520.

Referring to fig. 1 to 5, the driving device 300 may drive a plurality of cable reels 200 individually, but all are driven in unison by the driving motor 310. The display and control unit 530 and the controller 520 can manually control which driving assemblies 320 are put into use, that is, which cable drums 200 need to be controlled to perform cable unwinding or cable retraction.

The torque sensor 510 may detect a driving torque at an output end of the driving motor, and further determine whether the cable drums 200 can be driven to normally rotate according to the driving torque, and if the driving torque does not decrease to a preset torque safety threshold within a preset safety time, the controller 520 may actively control the first clutch 324 to disengage, so as to disengage the cable drums 200. When the first clutches 324 are disengaged, a mode of one-by-one disengagement can be adopted, the safety time is reset when the first clutches 324 are not disengaged until the driving torque is reduced below the torque safety threshold value, at this time, the driving torque is continuously collected, when the driving torque is reduced by a preset reinjection threshold value, one first clutch 324 is tried to be closed again, then the magnitudes of the driving torque and the torque safety threshold value are continuously judged, and if the magnitudes of the driving torque and the torque safety threshold value are smaller than the torque safety threshold value, one first clutch 324 is continuously closed until all first clutches 324 needing to be closed are closed again.

According to the control system of the cable winding and unwinding device provided by the embodiment of the invention, the torque sensor 510 can be used for detecting the driving torque of the driving device, so that the controller 520 can adjust the driving rotating speed according to the driving torque, and part of the cable drum can be separated when the driving torque is too large, so that the driving device is prevented from being locked. The display control unit 530 can check the driving moment in real time, so that an operator can conveniently manually input or withdraw the cable drum.

In some embodiments of the present invention, the display control unit 530 may adopt a single chip, a DSP, an ARM, or a PLC. Specifically, Siemens S7 series PLCs may be employed. The display control unit 530 may be a liquid crystal touch screen, or a combination of a liquid crystal display and a key.

In some embodiments of the present invention, referring to fig. 5, the cable reel control system further includes a plurality of distance detecting units 540 and a plurality of cable breakage detecting devices 550.

A plurality of distance detecting units 540 electrically connected to the controller 520 for detecting distances between the cables of the cable reels 200;

the cable breakage detecting devices 550, which are electrically connected to the controller 520, are respectively used for detecting the breakage status of the cable after the distance measurement by the distance detecting units 540.

A plurality of distance detecting element 540 set up in one side that the cable was put in the cable drum 200 exhibition, when cable drum 200 carried out the cable exhibition and put, the cable that the exhibition was put can be put away again after passing through distance detecting element 540, a plurality of cable damage detection device 550 set up in a plurality of rear ends apart from detecting element 540, the cable can further pass through cable damage detection device 550 after passing through distance detecting element 540, just count through the cable after the cable damage detection device 550 and accomplished complete exhibition and put the process.

The distance of the cable can be detected through the distance detection unit 540, so that the length of the cable can be actually known, and subsequent data calculation is facilitated. The cable broken detection device 550 can detect whether the broken cable is broken or not, and once the broken cable is found, the cable reel with the broken cable needs to be separated in time to give an alarm, so that field workers can handle the broken cable in time, and the broken cable is prevented from being put into use, so that accidents are avoided or dangers are brought to work. Damaged position can be confirmed to cable damage detection device 550, and distance detecting element 540 can detect the exhibition and put the distance to can confirm the damaged concrete positional information of cable, record concrete positional information through controller 520, then can be convenient for follow-up find damaged point when overhauing fast. Specifically, when the fault point is detected, the cable can be expanded again, when the cable is expanded to the distance corresponding to the specific position information, the cable is stopped to be expanded, and the maintenance personnel can maintain the cable at the moment.

In some embodiments of the present invention, the distance detection unit 540 employs a wheeled meter counter. The wheel type meter counter is arranged on one side of the cable reel 200 for unfolding the cable, the unfolded cable can be unfolded after passing through the wheel type meter counter, and the wheel type meter counter can detect the unfolding distance by utilizing the static friction between the wheel type meter counter and the unfolded cable.
