In the description of the present invention, it is to 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.

Generally, when a vehicle runs, the front slave plate 46 impacts the cluster plate seat 47 for a long time, and thus there is a possibility that the cluster plate seat 47 or the end face of the front slave plate 46 is slightly deformed or foreign matter such as particles enters between the front slave plate 46 and the tail part of the coupler 42, so that the front slave plate has a part of force to be transmitted to the tail part of the coupler 42, and the coupler yoke 43 bears a certain shearing force to the coupler 42 and the coupler yoke 41, and at this time, when the coupler yoke 43 is disassembled, the coupler yoke 43 cannot fall off freely after the support plate is removed, and the disassembly and assembly of the coupler 42 are difficult to achieve.

In one embodiment, referring to fig. 1 to 4, a device for disassembling and assembling a coupler 42 includes a mounting base 10 and a pushing mechanism 20. The mount 10 is detachably attached to the vehicle body 30, and is disposed in a recess 31 of the bottom surface of the vehicle body 30 at a distance from the coupler frame 41. The pushing mechanism 20 is configured to be mounted on the mounting base 10, and the pushing mechanism 20 is configured to push the coupler yoke 41 to move.

In the above-described device for removing and attaching the coupler 42, when the coupler 42 is removed, the mount 10 is mounted in the recess 31 of the bottom surface of the vehicle body 30, the pushing mechanism 20 is mounted on the mount 10, the hook frame 41 is pushed by the pushing mechanism 20 to move in the direction of the coupler 42, and the shearing force applied to the coupler pin 43 is released to smoothly and freely drop the coupler. After the coupler yoke 43 falls freely, the coupler 42 can be disassembled from the car body 30 smoothly and quickly, so that the disassembly and assembly operation of the coupler 42 can be facilitated, the labor is saved, and the operation safety is improved.

Further, referring to fig. 1 to 4, the mounting base 10 is a magnetic mounting base 10, and the magnetic mounting base 10 is magnetically fixed on a limiting frame 44 in the concave portion 31. In this way, the mounting seat 10 is fixed to the limiting frame 44 by magnetic attraction, and one end of the pushing mechanism 20 is mounted on the mounting seat 10, so that the mounting seat 10 and the pushing mechanism 20 can be quickly fixed in the concave portion 31 of the bottom surface of the vehicle body 30, and the working efficiency is high.

Further, referring to fig. 1 to 4, the mounting base 10 includes a substrate 11 and a panel 12 connected to the substrate 11. The substrate 11 is arranged in a notch on the bottom surface of the limiting frame 44, and the panel 12 is attached to the bottom surface of the limiting frame 44. The panel 12 is provided with a limiting sleeve 121, one end of the pushing mechanism 20 is arranged in the limiting sleeve 121, and the other end of the pushing mechanism 20 is used for being in interference fit with the coupler yoke 41. In this way, since the substrate 11 is disposed in the recess on the bottom surface of the position-limiting frame 44, the panel 12 is attached to the bottom surface of the position-limiting frame 44, and the mounting base 10 can be stably disposed on the position-limiting frame 44. In addition, the end of the pushing mechanism 20 is inserted into the limiting sleeve 121 for limiting and fixing, so that the pushing mechanism 20 is rapidly mounted on the mounting seat 10, and the working efficiency is high.

Further, referring to fig. 1 to 4, the pushing mechanism 20 is an extrusion cylinder, a cylinder body of the extrusion cylinder is sleeved in the limiting sleeve 121, and a nozzle of the extrusion cylinder is connected to the pump station through an oil pipe. Further, the pushing mechanism 20 may be a screw motor, a cylinder drive, a hydraulic cylinder drive, an electric cylinder drive, or the like.

Further, referring to fig. 1 to 4, one end of the pushing mechanism 20 is in interference fit with the mounting base 10, and a driving end of the pushing mechanism 20 is provided with a screw top 22 with an adjustable protruding length. The screw top 22 is used for interference fit with the coupler yoke 41. Thus, by adjusting the extension length of the spiral top 22, the end of the cylinder body of the extrusion cylinder is abutted against the panel 12, and the spiral top 22 is abutted against the end surface of the coupler tail frame 41 with a preset pressure, so that the pushing mechanism 20 can be stably installed between the limiting frame 44 and the coupler tail frame 41, and the subsequent pushing operation of the coupler tail frame 41 is facilitated.

Specifically, the driving end of the extrusion cylinder is provided with an adjustable screw top 22, and the screw top 22 is used for being in interference fit with the coupler yoke 41.

In one embodiment, referring to fig. 5 to 14, the device for disassembling and assembling the coupler 42 further includes a carrying mechanism 50 for carrying the coupler 42. 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 42. Specifically, the lifting mechanism 52 is a hydraulic lifting table, a cylinder lifting mechanism, a motor screw lifting mechanism, or an electric cylinder lifting mechanism. 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. In this way, when the coupler 42 needs to be removed, the movable base 51 can be moved to a position corresponding to the coupler 42 below the vehicle body 30, and for example, a bracket 53 corresponding to the coupler 42 is provided above the elevating mechanism 52, and the coupler 42 is lifted by the bracket 53 above the elevating mechanism 52, so that the carrier plate of the coupler yoke 43 and the coupler yoke 43 can be removed in sequence. After the coupler yoke 43 and the supporting plate are detached, the moving base 51 is pushed, the moving base 51 drives the lifting mechanism 52 to move, and then the lifting mechanism 52 drives the coupler 42 to be drawn out from the concave part 31 (the side wall structure forming the concave part 31 is also called a guide frame for guiding and mounting the coupler 42) on the bottom surface of the vehicle body 30; after the coupler 42 is horizontally removed from the body 30, the lifting mechanism 52 is lifted to lower and move the coupler 42, thereby completing the operation of detaching the coupler 42.

Further, referring to fig. 5 to 8, 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 42 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 42 of a truck on the ground may be moved on the ground to be attached and detached. 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. 6 to 10, the movable base 51 includes two movable base blocks 514 disposed at intervals and two cross beams 515 disposed at intervals.

Further, referring to fig. 6 to 10, 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 can be avoided in the process that the lifting hook 544 of the carrying mechanism 50 lifts the car hook 42 or the buffer 45. 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.

Further, referring to fig. 6 to 8, one end of the bottom surface of the lifting mechanism 52 is rotatably connected to the moving base 51, the other end of the bottom surface of the lifting mechanism 52 is provided with a rotatable adjusting screw 521, and the adjusting screw 521 is adjustably disposed on the moving base 51. Thus, the inclination degree of the supporting surface of the lifting mechanism 52 relative to the railway is correspondingly adjusted by adjusting the adjusting screw 521, so that the coupler 42 and the buffer 45 can be conveniently supported, the coupler 42 and the buffer 45 can be conveniently installed in an aligned mode, and the operation is convenient and fast.

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. 9 to 14, 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 42 on the lifting mechanism 52 to a preset position, or hoisting the coupler 42 in the preset position on the lifting mechanism 52.

Further, referring to fig. 9 to 14, the hanging mechanism 54 includes a supporting frame 541, a rope guiding wheel 542, a support 543, a hook 544, a pulling 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. 9 to 14, there are two crank handles, namely a neutral crank 547 and a deceleration crank 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. 9-14, 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 driving shaft 5492 and the shaft sleeve 5493 can synchronously rotate after the first key block 5494 is inserted into the first groove. 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.

Further, referring to fig. 9 to 14, the hanging mechanism 54 further includes a connecting sleeve 55. The connecting sleeve 55 is sleeved outside the driving shaft 5492, one end of the connecting sleeve 55 is connected with the support 543, and the other end of the connecting sleeve 55 is connected with the speed reducer 5491.

The supporting frame 541 comprises a supporting vertical rod 5411 and a supporting cross rod 5412 connected with the top of the supporting vertical rod 5411. The bottom of the vertical support rod 5411 is detachably mounted on the movable base 51, the support 543 is mounted on the vertical support rod 5411, and the rope guide wheel 542 is rotatably disposed on the horizontal support rod 5412. The support 541 is attached to the movable base 51 as needed, and when the support is not needed, the support 541 can be detached from the movable base 51.

Further, the supporting frame 541 further includes a supporting reinforcement rod 5413. Two ends of the supporting reinforcing rod 5413 are respectively connected with the supporting cross rod 5412 and the supporting vertical rod 5411. The support reinforcement 5413 provides structural stability between the support cross bar 5412 and the support vertical bar 5411 to withstand heavier couplers 42 or bumpers 45.

Further, referring to fig. 9 to 14, the vertical support bar 5411 is divided into an upper section and a lower section, and the upper section 5414 of the vertical support bar 5411 is rotatably connected to the lower section 5415 of the vertical support bar 5411. The coupler 42 can be conveniently carried in the process of driving the upper section 5414 of the vertical support rod 5411 to rotate relative to the lower section 5415 of the vertical support rod 5411. Furthermore, the upper section 5414 and the lower section 5415 are rotatably connected in a sleeved manner, the upper section 5414 is provided with a locking screw 5416, and the upper section 5414 can be fixed relative to the lower section 5415 by tightening the locking screw 5416.
