Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In the description of the present invention, it is to be understood that the terms "first", "second" and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the description of the present invention, it should be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.

Conventionally, for the disassembling operation of the coupler buffer 45, the coupler buffer 45 is generally pressed by the oil cylinder to make the coupler buffer 45 compressed, and the coupler buffer 45 can fall off the car body 30 after being compressed. However, when the coupler buffer 45 falls off from the vehicle body 30, on one hand, the coupler buffer 45 is heavy, and on the other hand, no special carrying equipment is provided, so that the coupler buffer 45 collides with the hook guide 48 after being detached, and thus, a safety accident is caused, and the safety is low.

In one embodiment, referring to fig. 1 to 9, a device for disassembling and assembling a coupler draft gear 45 includes a main push cylinder 10 and a positioning member 20. The main push cylinder 10 is arranged in the coupler tail frame 41, and the main push cylinder 10 includes a push end 11 and a bottom end 12 opposite to the push end 11. The pushing end 11 is intended to abut against the front slave plate 46. An inlet pipe 121 and an outlet pipe 121 are arranged on the bottom end 12. The inlet and outlet pipe 121 is connected with a pipeline joint 13, the pipeline joint 13 is used for being connected with a pump station, the inlet and outlet pipe 121 and the pipeline joint 13 are both positioned in the concave part 31 of the bottom surface of the vehicle body 30, and the pipeline joint 13 is positioned outside the coupler yoke 41. The positioning element 20 is configured to be disposed in the installation hole 411 of the coupler yoke 41, and the positioning element 20 is in interference fit with the bottom end 12.

Specifically, the main push cylinder 10 may be a cylinder, a hydraulic cylinder, an air cylinder, or an electric cylinder.

In the dismounting device of the coupler buffer 45, the positioning piece 20 has a positioning effect on the main push cylinder 10, the pushing end 11 of the main push cylinder 10 extrudes the coupler buffer 45 when extending, after the coupler buffer 45 is compressed, the front slave plate 46 does not tightly abut against the cluster plate seat 47, and the coupler buffer 45 and the coupler yoke 41 are separated from the concave part 31 on the bottom surface of the car body 30 under the action of gravity, so that the main push cylinder 10 and the positioning piece 20 are conveniently mounted in the car body 30 for dismounting, and the dismounting process is simple. In addition, since the inlet/outlet pipe 121 and the pipeline joint 13 are both located in the concave portion 31 of the bottom surface of the car body 30, and the pipeline joint 13 is located outside the coupler yoke 41, in the instant that the coupler bumper 45 and the coupler yoke 41 are separated from the car body 30 from the concave portion 31 of the bottom surface of the car body 30, the pipe externally connected to the pipeline joint 13 can directly drop downwards to avoid the hook guide frame 48, so that collision with the hook guide frame 48 can be avoided, and safety is improved.

Further, referring to fig. 2 and fig. 3, a positioning groove 122 is disposed in a middle portion of an end surface of the bottom end 12, the positioning member 20 is provided with a positioning boss 21, and the positioning boss 21 is disposed in the positioning groove 122. Thus, after the positioning groove 122 is installed in cooperation with the positioning boss 21 of the positioning member 20, the main pushing cylinder 10 ensures that the acting point of the output force is kept at the middle part of the front slave plate 46 when pushing the front slave plate 46, and ensures that the two ends of the front slave plate 46 are compressed in parallel and at equal intervals, so that the buffer can be smoothly extruded, the bad phenomenon that the buffer cannot be extruded when receiving the oblique acting force is avoided, and the buffer is conveniently compressed to separate the front slave plate 46 from the plate-clumping seat 47.

Further, referring to fig. 3, the side wall of the positioning member 20 includes at least two side walls, wherein one side wall is provided with the positioning boss 21, and the other side wall is an arc-shaped surface, and the arc-shaped surface is used for abutting against the hole wall of the installation hole 411. Specifically, the positioning member 20 is a pressing pin having a semicircular cross section perpendicular to the axial direction, for example.

Further, referring to fig. 3 to 8, the device for disassembling and assembling the coupler buffer 45 further includes a hydraulic lock 14. The pipe joint 13 is connected to the inlet and outlet pipes 121 through the hydraulic lock 14. The number of the inlet pipes 121 and the number of the pipeline joints 13 are two, and the two pipeline joints 13 and the two inlet pipes 121 are arranged correspondingly one by one. The two inlet and outlet pipes 121 are respectively located at two sides of the positioning member 20. Therefore, on one hand, after the coupler buffer 45 is compressed by the main push cylinder 10 by a preset amount, the main push cylinder 10 does not compress the coupler buffer 45 any more, namely, the pump station stops supplying oil or supplying air, at the moment, under the action of the hydraulic lock 14, the compression state of the coupler buffer 45 is continuously ensured, and the phenomenon that the coupler buffer 45 rebounds to influence the disassembly operation of the coupler buffer 45 can be avoided.

Further, referring to fig. 3 to 9, the pipeline joint 13 is disposed on a bottom surface of the hydraulic lock 14, and the direction of oil inlet and outlet of the pipeline joint 13 is perpendicular to the bottom surface of the hydraulic lock 14. That is, the oil inlet and outlet direction of the pipeline joint 13 is perpendicular to the axial direction of the main push cylinder 10, and the pipeline joint 13 faces the rail, so that collision between the inlet and outlet pipe 121 and the car body 30 can be avoided to a certain extent when the main push cylinder 10 is connected with the pump station and then the coupler buffer 45 is disassembled and the coupler buffer 45 falls down in the main push cylinder 10.

In one embodiment, referring to fig. 10 to 19, the device for disassembling and assembling the coupler draft gear 45 further includes a carrying mechanism 50 for carrying the coupler draft gear 45. The carrying mechanism 50 includes a movable base 51 and a lifting mechanism 52. The lifting mechanism 52 is disposed on the movable base 51, and the lifting mechanism 52 is used for lifting the coupler buffer 45. Specifically, the lifting mechanism 52 is a hydraulic lifting table, an air cylinder lifting mechanism 52, an oil cylinder lifting mechanism 52, a motor screw lifting mechanism 52, or an electric cylinder lifting mechanism 52. The lifting mechanism 52 is a hydraulic lifting table in this embodiment, and includes, but is not limited to, a scissor lift table, a telescopic arm lift table, or a folding arm lift table. Thus, when the coupler buffer 45 needs to be removed, the coupler buffer 45 can be moved to a position corresponding to the coupler buffer 45 below the vehicle body 30 through the movable base 51, for example, a bracket 53 corresponding to the coupler buffer 45 is arranged above the lifting mechanism 52, the coupler buffer 45 falls onto the bracket 53 after being separated from the vehicle body 30, the coupler buffer 45 is lifted by the bracket 53, the movable base 51 is pushed, the movable base 51 drives the lifting mechanism 52 to move, and the lifting mechanism 52 drives the coupler buffer 45 to move outwards from the lower part of the vehicle body 30; after the coupler buffer 45 is horizontally moved out, the lifting mechanism 52 lifts to lower and move the coupler buffer 45, and the disassembly operation of the coupler buffer 45 is completed. The installation operation of the coupler buffer 45 is just opposite to the disassembly operation of the coupler buffer 45, and the description is omitted.

In fig. 12 and 13, the coupler 42 is mounted on a bracket 53 above the lifting mechanism 52, and the coupler 42 is lifted and lowered. It is understood that the bracket 53 above the lifting mechanism 52 may be designed to match the coupler draft gear 45 as required, and is used to mount the coupler draft gear 45 and lift the coupler draft gear 45, thereby facilitating the removal and installation of the coupler draft gear 45.

Further, referring to fig. 10 to 13, one side of the movable base 51 is provided with two or more first traveling wheels 511 at intervals. The other side of the movable base 51 is provided with more than two second travelling wheels 512 at intervals, and the first travelling wheel 511 and the second travelling wheel 512 are respectively used for travelling on two rails 60 of a railway. Thus, the movable base 51 can be easily moved on the rail 60 of the railway, and the coupler draft gear 45 of the train on the railway can be easily attached and detached on line. Of course, the present invention is not limited to the application to a train of a railway, and the coupler draft gear 45 of a truck on the ground may be removed and installed by moving the truck on the ground. Specifically, two or more first traveling wheels 511 are in one-to-one correspondence with two or more second traveling wheels 512, and are connected by a connecting shaft 513.

Further, referring to fig. 11 to 15, the movable base 51 includes two movable base blocks 514 disposed at intervals and two cross beams 515 disposed at intervals. The two ends of the cross beam 515 are respectively connected with the two movable seat blocks 514. The first traveling wheel 511 and the second traveling wheel 512 are respectively disposed on the two movable seat blocks 514.

Further, referring to fig. 11 to 15, the movable base 51 further includes more than one anti-rollover element disposed on the movable base block 514. The anti-rollover assembly is arranged on the side surface of the rail 60. Thus, under the action of the rollover prevention assembly, the adverse phenomenon of rollover during the process of hoisting the car hook 42 or the car hook buffer 45 by the hoisting hook 544 of the carrying mechanism 50 can be avoided. Specifically, the movable seat block 514 is provided with two through holes 516 respectively located at two sides of the rail 60, and the rollover prevention assembly includes a rail locking fork 517 and two rail locking pins 518. The two leg portions of the rail locking fork 517 are inserted into the two through holes 516 and located at two sides of the rail 60, and two rail locking pins 518 are respectively installed on the two leg portions.

In a feasible scheme, the anti-rollover component can also be two anti-rollover hooks respectively arranged on two side surfaces of the rail 60, and the two anti-rollover hooks are respectively positioned on the two side surfaces of the rail 60 to play a role in preventing rollover. The anti-rollover hook is detachably disposed on the movable seat block 514, or is integrally formed with the movable seat block 514.

Specifically, one end of the bottom surface of the lifting mechanism 52 is disposed on one of the beams 515, and the adjusting screw 521 is disposed on the other beam 515 in a position-adjustable manner.

Further, referring to fig. 14 to 19, the carrying mechanism 50 further includes a hanging mechanism 54 disposed on the movable base 51. The hoisting mechanism 54 is used for hoisting the coupler buffer 45 on the lifting mechanism 52 to a preset position, or hoisting the coupler buffer 45 at the preset position on the lifting mechanism 52.

Further, referring to fig. 14 to 19, the hanging mechanism 54 includes a support frame 541, a rope guiding wheel 542, a support 543, a hook 544, a pull rope 545, a winding shaft 546 and a crank. The supporting frame 541 is installed on the moving base 51, the rope guide wheel 542 and the support 543 are installed on the supporting frame 541, the winding shaft 546 is rotatably installed on the support 543, the crank drives the winding shaft 546 to rotate to wind or unwind the pull rope 545, and the pull rope 545 bypasses the rope guide wheel 542 and is connected with the hook 544.

Further, referring to fig. 14-19, there are two of the handles, a neutral handle 547 and a retard handle 548. The hanging mechanism 54 further includes a reducer 5491 and a driving shaft 5492. The reducer 5491 is specifically a worm gear reducer 5491. The speed reducer 5491 is provided with a power input end and a power output end, the power input end is connected with the speed reducing crank 548, the power output end is provided with a shaft sleeve 5493 sleeved outside the driving shaft 5492, the winding shaft 546 is provided with a shaft hole coaxial with the shaft sleeve 5493, the driving shaft 5492 is further sleeved in the shaft hole, the end part of the driving shaft 5492 is connected with the neutral crank 547, and the driving shaft 5492 can drive the winding shaft 546 to rotate.

The driving shaft 5492 is movable along the axial direction of the shaft hole, and when the driving shaft 5492 moves to a first position along the axial direction of the shaft hole, the driving shaft 5492 can drive the shaft sleeve 5493 to rotate; when the drive shaft 5492 is moved to a second position along the axial direction of the shaft hole, the drive shaft 5492 can rotate relative to the boss 5493.

The boss 5493 may be located outside the main body of the speed reducer 5491 or may be embedded in the main body of the speed reducer 5491.

In one embodiment, referring to fig. 14-19, the shaft housing 5493 is keyed to rotate the drive shaft 5492. For example, the inner wall of the shaft sleeve 5493 is provided with a first groove, the outer wall of the driving shaft 5492 is provided with a first key block 5494 capable of being movably inserted into the first groove, and the first key block 5494 can be inserted into the first groove to realize synchronous rotation of the driving shaft 5492 and the shaft sleeve 5493. It will be appreciated that the first recess and first tab 5494 may be reversed on the drive shaft 5492 and the boss 5493.

Likewise, the drive shaft 5492 drives the take-up shaft 546 to rotate in a spline-driven manner. For example, a second groove is formed in the inner wall of the shaft hole, a second key block 5495 capable of being movably inserted into the second groove is arranged on the outer wall of the driving shaft 5492, and the driving shaft 5492 and the winding shaft 546 can synchronously rotate after the second key block 5495 is inserted into the second groove. It will be appreciated that the second recess and second tab 5495 may be reversed on the drive shaft 5492 and boss 5493.

So, promote drive shaft 5492 to first position along the axial direction in shaft hole, because drive shaft 5492 can drive axle sleeve 5493 and rotate, that is to say axle sleeve 5493 can drive axle sleeve 5492 and rotate, like this, when speed reduction crank 548 drives power input end and rotates, under reduction gear 5491 deceleration, the corresponding drive shaft 5492 that drives of axle sleeve 5493 of reduction gear 5491 rotates, and drive shaft 5492 correspondingly drives rolling axle 546 and carries out the rolling or unreel, can greatly increased lifting force. Promote drive shaft 5492 to the second position along the axial direction in shaft hole, because drive shaft 5492 can rotate for axle sleeve 5493, namely no longer drive shaft 5492 when axle sleeve 5493 rotates and rotate, at this moment, reduction gear 5491 does not exert an effect to drive shaft 5492, alright so with drive shaft 5492 through neutral crank 547 and rotate, drive shaft 5492 correspondingly drives wind-up shaft 546 and carries out quick rolling or unreel for the activity duration shortens greatly.
