Description

Technical Field

[0001] The invention relates to the technical field of hoisting equipment, in particular to a hoisting device for track sleeper separation. Background Art

[0002] The hoisting device is an indispensable and important equipment in rail transit construction. With the rapid development of rail transit construction, the technical requirements for the hoisting device of the distributed sleeper device are also increasing. The reference patent of the distributed sleeper device is CN209636566U.

[0003] Traditional lifting methods traditionally use manual labor in conjunction with mechanical equipment such as gantry cranes to lift the distributed sleeper device. This method requires manual installation of the lifting fixture on the distributed sleeper device, and then the distributed sleeper device is lifted to the designated location by mechanical equipment. Although this method is flexible, it is relatively inefficient and highly dependent on manual labor.

[0004] Existing lifting devices adopt a single-point or a few-point clamping method. This method is prone to cause the hoisted object to shake or tilt due to uneven force during the lifting process, increasing the risk and uncertainty of the operation. Especially in complex environments, such as strong winds and uneven ground, the single-point clamping lifting device is more susceptible to external factors, causing the hoisted object to lose control or fall, thereby causing safety accidents. Since the force points are single or few, it is easy to produce offset or deformation due to uneven force, thereby affecting the positioning and installation accuracy of the hoisted object. Although single-point or a few-point clamping may be relatively simple to operate, due to its lack of stability and safety, it often requires more monitoring and adjustment during the operation, increasing the complexity and difficulty of the operation. Summary of the invention

[0005] The object of the present invention is to provide a lifting device for track sleeper separation to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A lifting device for track sleeper distribution, the lifting device comprises a gantry, a sports car electric hoist, a clamp mechanism, a traveling mechanism and a traveling track, the gantry and the sports car electric hoist are slidably connected, the clamp mechanism and the sports car electric hoist are fixedly connected, the traveling mechanism and the gantry are fixedly connected, and the traveling track and the traveling mechanism are slidably connected;

[0008] The clamping mechanism includes a mounting plate No. 1, a positioning unit, a control unit and a clamping unit. The mounting plate No. 1 is fixedly connected to the positioning unit. Four positioning units are provided. Four control units are provided. The control unit is fixedly connected to the mounting plate No. 1. Eight clamping units are provided. The clamping unit and the control unit are fixedly connected.

[0009] The main body of the lifting device is a gantry, on which a sports car electric hoist is installed to provide the lifting and carrying functions for the lifting device. The distributed sleeper device to be carried is clamped by a clamp mechanism to prevent the distributed sleeper device from falling during transportation and to reduce shaking during transportation. The lifting device can be moved as a whole through the walking mechanism, and does not need to be disassembled when it needs to be transferred. Other components are installed and supported by the No. 1 mounting plate, and the positioning unit is driven in sequence to position the distributed sleeper device before clamping it, ensuring that the clamping unit can accurately clamp the distributed sleeper device, reducing the technical requirements of the operator. It can be required that four control units are used to control the conversion of the two states of release and clamping readiness of eight clamping units, so that manual clamping and loosening are not required during transportation, thereby improving the transportation efficiency. Eight clamping units are set to clamp the four corners of the distributed sleeper device to ensure that the distributed sleeper device is more evenly stressed during the lifting process, reducing the risk of deformation or damage caused by excessive force on a single point. By setting eight clamping units, if one of the clamping units fails during transportation, sufficient supporting force can still be provided to avoid the distributed sleeper device falling due to failure of the clamping unit during transportation.

[0010] Furthermore, the positioning unit includes a base, a motor, a fixed plate and a positioning rod, the base and the No. 1 mounting plate are fixedly connected, the motor and the base are fixedly connected, the motor output end and the positioning rod are fixedly connected, and the fixed plate and the positioning rod are rotatably connected.

[0011] The motor drives the positioning rod to rotate toward the distributed sleeper device. The four positioning rods rotate in sequence. When the positioning rod hits the distributed sleeper device, a reaction force is generated, so that the clamp mechanism drives the sports car electric hoist to move, thereby accurately positioning the clamp mechanism to the distributed sleeper device.

[0012] Furthermore, the control unit includes a No. 1 slide bar, an arc plate, a block, a fixed rod, a slider, a guide plate, a limit unit, a No. 2 mounting plate and a four-rope elevator. The No. 1 slide bar is fixedly connected to the clamping unit, the No. 1 slide bar is fixedly connected to the four-rope elevator, the arc plate is provided with four, the arc plate is fixedly connected to the No. 1 mounting plate, the No. 1 slide bar is slidably connected to the arc plate, the arc plate is fixedly connected to the block, the block is fixedly connected to the fixed rod, the block is provided with a No. 1 through hole, the No. 1 slide bar is slidably connected to the No. 1 through hole, and the slider is provided with two No. through hole, No. 1 slide bar and No. 2 through hole are slidably connected, the slider and No. 2 mounting plate abut, the fixed rod and the block are fixedly connected, the slider is provided with No. 3 through hole, the fixed rod and No. 3 through hole are slidably connected, the guide plate and the fixed rod are fixedly connected, the guide plate and the clamping unit are slidably connected, four limit units are provided, the limit unit and No. 1 slide bar are fixedly connected, the No. 2 mounting plate and the clamping unit are hinged, the No. 2 mounting plate is provided with No. 4 through hole, the fixed rod and the No. 4 through hole are slidably connected, and the four-rope hoist and No. 1 mounting plate are fixedly connected.

[0013] The block is fixed by an arc plate, and a fixing rod is installed on the block, and the fixing rod is passed through the slider and the No. 2 mounting plate through the No. 3 through hole and the No. 4 through hole, and is not affected by the movement of the fixing rod, so that the guide plate connected with the fixing rod is fixed, and the No. 1 through hole provided on the block and the No. 2 through hole provided on the slider are connected, so that the No. 2 mounting plate moves with the No. 1 sliding rod, and the steel wire rope is extended by the four-rope hoist drive, so that the No. 1 sliding rod descends, driving the limit unit and the No. 2 mounting plate to descend, and the clamping unit is driven to descend as the No. 2 mounting plate descends. Under the action of the guide plate, the clamping unit is gradually stretched, and as the limit unit descends, the limit unit will move between the block and the slider, and then the four-rope hoist drives the steel wire rope to contract, and the limit unit will be stuck on the block. , so that the No. 1 slide bar fixed on the limit unit cannot move upward, so that the four-rope elevator cannot drive the wire rope to retract, and the clamping unit is in a loosened state. When the clamping unit needs to be switched from a loose state to a clamping-ready state, the wire rope is driven by the four-rope elevator to continue to extend, so that the No. 1 slide bar descends, driving the limit unit to descend to the lower half of the slider. At this time, the four-rope elevator drives the wire rope to retract, and the limit unit drives the slider to rise, and embeds the upper half of the slider into the block, so that the limit unit can move from the lower half of the slider to the side of the block, and then leave the block and continue to rise to the initial state, so that the clamping unit returns to the clamping-ready state. By providing four limit units and evenly distributing them on the No. 1 slide bar, it is ensured that it can hook the block and drive the slider to move.

[0014] Furthermore, the clamping unit includes a No. 1 connecting rod, a No. 2 connecting rod and a No. 1 L-shaped claw hook, the No. 1 connecting rod and the No. 2 mounting plate are hingedly connected, the No. 2 connecting rod and the No. 1 connecting rod are hingedly connected, and the No. 1 L-shaped claw hook and the No. 2 connecting rod are hingedly connected.

[0015] By hingedly connecting the No. 2 mounting plate, the No. 1 connecting rod, the No. 2 connecting rod and the No. 1 L-shaped claw hook in sequence, the No. 1 connecting rod, the No. 2 connecting rod and the No. 1 L-shaped claw hook form a connecting rod chain. When the No. 2 mounting plate rises, the connecting rod chain moves relatively according to the contour of the distributed sleeper device, so that the connecting rod chain fits the contour of the distributed sleeper device more closely. By setting eight clamping units and evenly distributing them at the four corners of the distributed sleeper device, the No. 1 L-shaped claw hook can apply sufficient clamping force to the distributed sleeper device and make the force more uniform, thereby ensuring that the distributed sleeper device is stable and will not slip during the lifting process.

[0016] Furthermore, the limiting unit includes a fixed block, a No. 3 connecting rod, a No. 4 connecting rod and a No. 2 L-shaped claw hook, the fixed block and the No. 1 sliding rod are fixedly connected, the fixed block and the arc plate are slidably connected, the No. 3 connecting rod and the fixed block are hingedly connected, the No. 4 connecting rod and the No. 3 connecting rod are hingedly connected, and the No. 2 L-shaped claw hook and the No. 4 connecting rod are hingedly connected.

[0017] When the first slide bar is lifted up, the second L-shaped claw hook is used to hook the slider and the first slide bar to the bottom of the slide bar, so that the slider is locked. Under the action of the rising force of the first slide bar, the second L-shaped claw hook continues to move along the contour of the slider to the contour of the block, and then leaves the block and returns to its initial position.

[0018] Furthermore, the clamping block is provided with a No. 1 inclined surface, the sliding block is provided with two No. 2 inclined surfaces, and the clamping block is provided with a tapered groove, which cooperates with the No. 2 inclined surface on the upper portion of the sliding block.

[0019] The card block is provided with a No. 1 inclined surface, so that the outline of the card block is inclined, and the No. 2 L-shaped claw hook can slide smoothly on the No. 1 inclined surface. The card block is provided with a tapered groove, so that the No. 2 L-shaped claw hook can be hooked on the card block. By making the tapered groove match the No. 2 inclined surface on the upper part of the slider, the upper half of the slider can be nested in the tapered groove, and the No. 2 inclined surface on the lower half of the slider is connected with the No. 1 inclined surface of the card block, so that the No. 2 L-shaped claw hook can transition along the No. 2 inclined surface of the slider to the No. 1 inclined surface of the card block.

[0020] Furthermore, the walking mechanism includes a shell, wheels, buffer plates, springs, a second slide bar, gears, cams, a driven rod and a brake block. The shell and the door frame are fixedly connected, the wheels and the shell are rotatably connected, the springs and the shell are fixedly connected, the buffer plate and the spring are fixedly connected, the second slide bar and the buffer plate are fixedly connected, the second slide bar and the shell are slidably connected, the gears and the second slide bar are transmission-connected, the cam and the gears are fixedly connected, the gears and the shell are rotatably connected, the driven rod and the cam are slidably connected, and the brake block and the driven rod are fixedly connected.

[0021] The outer shell can effectively prevent the wheel from being hit by external objects during operation, thus protecting the wheel; the buffer plate and the spring are fixedly connected to reduce the impact force when the walking mechanism is hit or collides due to operating errors; the buffer plate and the No. 2 slide bar are fixedly connected to drive the No. 2 slide bar to rotate the gear, thereby rotating the cam, so that the driven rod connected to it moves downward, and drives the brake block to move downward and contact the track, generating friction, so that when the wheel slides due to the collision of the walking mechanism, the friction force of the brake block on the track reduces the sliding distance and stops.

[0022] Furthermore, the cam is provided with a sliding groove, the top end of the driven rod is spherical, the sliding groove and the driven rod are slidably connected, and the second sliding rod is provided with gear teeth, which are meshed with the gear.

[0023] The cam is provided with a sliding groove and the spherical fit at the top of the driven rod, so that the driven rod is stuck on the cam and moves with the rotation of the cam. By providing gear teeth on the second slide bar and engaging with the gear, the second slide bar can drive the gear to rotate. By setting the number of gear teeth to one-fourth of the gear, the gear only rotates one-fourth, so that the cam rotates just one-fourth, and the driven rod drives the brake block to contact the track.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Eight hooks are used to clamp the four corners of the distributed sleeper device respectively, which can ensure that the distributed sleeper device is subjected to balanced force during lifting and reduce the risk of deformation or damage caused by excessive force at a single point. The synergistic effect of multiple hooks enables the lifting device to more accurately control the position and posture of the truss, meet the needs of high-precision lifting, and achieve precise positioning. The positioning unit and eight claw hooks and the multi-point clamping design simplify the lifting operation process and reduce the skill requirements for operators. Each hook is relatively independent, which is convenient for individual inspection and replacement, reducing maintenance costs and time.

[0026] 2. Multi-point clamping enhances the overall stability of the lifting system, effectively reduces the shaking and swinging of the truss during the lifting process, and improves the safety and accuracy of the lifting. In complex environments such as strong winds and uneven ground, the multi-point clamping lifting device can better maintain stability and ensure the smooth progress of the lifting operation.

[0027] 3. Multiple grab hooks work at the same time. Even if one or several of them fail, the other grab hooks can still provide sufficient support to prevent the split-pillow platform from falling accidentally. By improving the stability and safety of the lifting process, the risk of accidents caused by lifting errors or improper operation is reduced.

[0028] 4. When a collision occurs, the impact force of the walking mechanism is reduced through the buffer plate connected to the spring. The buffer plate drives the slide bar to drive the gear and cam to rotate, so that the driven rod moves down, and the brake block contacts the track to generate friction, effectively shortening the distance the wheel slides due to collision and stops.

[0041] Example: Figure 1-Figure 10As shown, the present invention provides a technical solution for a lifting device for track sleepers, the lifting device comprises a gantry 1, a sports car electric hoist 2, a clamp mechanism 3, a walking mechanism 4 and a walking track 5, the gantry 1 and the sports car electric hoist 2 are slidably connected, the clamp mechanism 3 and the sports car electric hoist 2 are fixedly connected, the walking mechanism 4 and the gantry 1 are fixedly connected, and the walking track 5 and the walking mechanism 4 are slidably connected;

[0042] The clamping mechanism 3 includes a mounting plate No. 1 31, a positioning unit 32, a control unit 33 and a clamping unit 34. The mounting plate No. 1 31 and the positioning unit 32 are fixedly connected. Four positioning units 32 are provided. Four control units 33 are provided. The control unit 33 and the mounting plate No. 1 31 are fixedly connected. Eight clamping units 34 are provided. The clamping unit 34 and the control unit 33 are fixedly connected.

[0043] The main body of the lifting device is a gantry 1, on which a sports car electric hoist 2 is installed to provide the lifting and carrying functions for the lifting device. The distributed sleeper device to be carried is clamped by a clamp mechanism 3 to prevent the distributed sleeper device from falling during the transportation process and to reduce the shaking during the transportation process. The lifting device can be moved as a whole through a walking mechanism 4, and does not need to be disassembled when it needs to be transferred. Other components are installed and supported by a No. 1 mounting plate 31. The positioning unit 32 is driven in sequence to position the distributed sleeper device before clamping it, ensuring that the clamping unit 34 can accurately clamp the distributed sleeper device, reducing the skill requirements of the operator. It is required that four control units 33 be used to control the conversion of the two states of release and clamping readiness of eight clamping units 34, so that no manual clamping and loosening are required during transportation, thereby improving the transportation efficiency; eight clamping units 34 are set to clamp the four corners of the distributed sleeper device to ensure that the distributed sleeper device is subjected to more uniform force during lifting, thereby reducing the risk of deformation or damage caused by excessive force on a single point; and eight clamping units 34 are set to ensure that if one of the clamping units 34 fails during transportation, sufficient supporting force can still be provided to avoid the distributed sleeper device falling due to failure of the clamping unit 34 during transportation.

[0045] The motor 322 drives the positioning rod 324 to rotate toward the distributed sleeper device. The four positioning rods 324 rotate in sequence, and a reaction force is generated when the positioning rod 324 hits the distributed sleeper device, so that the clamp mechanism 3 drives the sports car electric hoist 2 to move, thereby accurately positioning the clamp mechanism 3 to the distributed sleeper device.

[0046] like Figure 3 to Figure 6 As shown, the control unit 33 includes a No. 1 slide bar 331, an arc plate 332, a block 333, a fixed rod 334, a slider 335, a guide plate 336, a limit unit 337, a No. 2 mounting plate 338 and a four-rope elevator 339, the No. 1 slide bar 331 is fixedly connected to the clamping unit 34, the No. 1 slide bar 331 is fixedly connected to the four-rope elevator 339, the arc plate 332 is provided with four, the arc plate 332 is fixedly connected to the No. 1 mounting plate 31, the No. 1 slide bar 331 is slidably connected to the arc plate 332, the arc plate 332 is fixedly connected to the block 333, the block 333 is fixedly connected to the fixed rod 334, the block 333 is provided with a No. 1 through hole 3331, the No. 1 slide bar 331 is slidably connected to the No. 1 through hole 3331, the slider 335 is provided with two No. 3 through hole 3351, the first slide bar 331 and the second through hole 3351 are slidably connected, the slider 335 and the second mounting plate 338 abut, the fixed rod 334 and the block 333 are fixedly connected, the slider 335 is provided with a third through hole 3352, the fixed rod 334 and the third through hole 3352 are slidably connected, the guide plate 336 and the fixed rod 334 are fixedly connected, the guide plate 336 and the clamping unit 34 are slidably connected, four limiting units 337 are provided, the limiting units 337 and the first slide bar 331 are fixedly connected, the second mounting plate 338 and the clamping unit 34 are hinged, the second mounting plate 338 is provided with a fourth through hole 3381, the fixed rod 334 and the fourth through hole 3381 are slidably connected, and the four-rope hoist 339 and the first mounting plate 31 are fixedly connected.

[0047] The block 333 is fixed by the arc plate 332, and the fixing rod 334 is installed on the block 333, and the fixing rod 334 passes through the slider 335 and the second mounting plate 338 through the third through hole 3352 and the fourth through hole 3381, and is not affected by the movement thereof, so that the guide plate 336 connected with the fixing rod 334 is fixed, and the second mounting plate 338 is connected through the first through hole 3331 provided on the block 333 and the second through hole 3351 provided on the slider 335, so that the second mounting plate 338 is The mounting plate 338 moves with the first slide bar 331, and the steel wire rope is extended by the four-rope elevator 339, so that the first slide bar 331 descends, driving the limit unit 337 and the second mounting plate 338 to descend. As the second mounting plate 338 descends, the clamping unit 34 is driven to descend. Under the action of the guide plate 336, the clamping unit 34 is gradually stretched open. As the limit unit 337 descends, the limit unit 337 moves to between the block 333 and the slider 335. At this time, the four-rope elevator 339 drives the steel wire rope to retract. When the clamping unit 34 is in a state of being released, the four-rope elevator 339 drives the steel wire rope to continue to extend, so that the first slide bar 331 is driven to descend, and the limiting unit 337 is driven to descend to the lower half of the slider 335. At this time, the four-rope elevator 339 drives the steel wire rope to continue to extend, and the first slide bar 331 is driven to descend to the lower half of the slider 335. The moving wire rope contracts, and the limit unit 337 drives the slider 335 to rise, and the upper part of the slider 335 is nested in the block 333, so that the limit unit 337 can move from the lower part of the slider 335 to the side of the block 333, and then leave the block 333 and continue to rise to the initial state, so that the clamping unit 34 returns to the clamping ready state. By providing four limit units 337 and evenly distributing them on the No. 1 slide bar 331, it is ensured that they can hook the block 333 and drive the slider 335 to move.

[0048] like Figure 3 and Figure 4 As shown, the clamping unit 34 includes a No. 1 connecting rod 341, a No. 2 connecting rod 342 and a No. 1 L-shaped claw hook 343, the No. 1 connecting rod 341 and the No. 2 mounting plate 338 are hingedly connected, the No. 2 connecting rod 342 and the No. 1 connecting rod 341 are hingedly connected, and the No. 1 L-shaped claw hook 343 and the No. 2 connecting rod 342 are hingedly connected.

[0049] By hingedly connecting the No. 2 mounting plate 338, the No. 1 connecting rod 341, the No. 2 connecting rod 342 and the No. 1 L-shaped claw hook 343 in sequence, the No. 1 connecting rod 341, the No. 2 connecting rod 342 and the No. 1 L-shaped claw hook 343 form a connecting rod chain. When the No. 2 mounting plate 338 rises, the connecting rod chain moves relative to the contour of the distributed sleeper device, so that the connecting rod chain fits the contour of the distributed sleeper device more closely. By setting eight clamping units 34 and evenly distributing them at the four corners of the distributed sleeper device, the No. 1 L-shaped claw hook 343 can apply sufficient clamping force to the distributed sleeper device and make the force more uniform, thereby ensuring that the distributed sleeper device is stable and will not slip during the lifting process.

[0050] like Figure 3 and Figure 7 As shown, the limiting unit 337 includes a fixed block 3371, a third connecting rod 3372, a fourth connecting rod 3373 and a second L-shaped claw hook 3374, the fixed block 3371 and the first sliding rod 331 are fixedly connected, the fixed block 3371 and the arc plate 332 are slidably connected, the third connecting rod 3372 and the fixed block 3371 are hingedly connected, the fourth connecting rod 3373 and the third connecting rod 3372 are hingedly connected, and the second L-shaped claw hook 3374 and the fourth connecting rod 3373 are hingedly connected.

[0051] The limiting unit 337 and the first slide bar 331 are fixed by the fixing block 3371, and the fixing block 3371, the third connecting rod 3372, the fourth connecting rod 3373 and the second L-shaped claw hook 3374 are hingedly connected in sequence, so that the third connecting rod 3372, the fourth connecting rod 3373 and the second L-shaped claw hook 3374 form a connecting rod chain, so that when the first slide bar 331 moves downward, the limiting unit 337 can move along the contour of the block 333 and the slider 335, and through the second L-shaped claw hook 3374, the limiting unit 337 can hook the block 333 when it rises with the first slide bar 331, thereby The rising of the No. 1 slide bar 331 is limited. When it wants to continue to rise, the No. 1 slide bar 331 continues to descend, and the limit unit 337 descends along the contour of the slider 335 to the lower half of the slider 335. The No. 1 slide bar 331 is rising, and the No. 2 L-shaped claw hook 3374 hooks the slider 335 and drives it to rise, so that the upper half of the slider 335 is nested in the block 333, so that the slider 335 is stuck. Under the action of the rising force of the No. 1 slide bar 331, the No. 2 L-shaped claw hook 3374 continues to move along the contour of the slider 335 to the contour of the block 333, and then leaves the block 333 and returns to the initial position.

[0053] The block 333 is provided with a No. 1 inclined surface, so that the outline of the block 333 is inclined, and the No. 2 L-shaped claw hook 3374 can slide smoothly on the No. 1 inclined surface. The block 333 is provided with a tapered groove 3332, so that the No. 2 L-shaped claw hook 3374 can be hooked on the block 333. By making the tapered groove 3332 cooperate with the No. 2 inclined surface on the upper part of the slider 335, the upper half of the slider 335 can be nested in the tapered groove 3332, and the No. 2 inclined surface on the lower half of the slider 335 and the No. 1 inclined surface of the block 333 are connected, so that the No. 2 L-shaped claw hook 3374 can transition along the No. 2 inclined surface of the slider 335 to the No. 1 inclined surface of the block 333.

[0054] like Figure 8 and Fig. 9 As shown, the walking mechanism 4 includes a shell 41, a wheel 42, a buffer plate 43, a spring 44, a second slide bar 45, a gear 46, a cam 47, a driven rod 48 and a brake block 49. The shell 41 is fixedly connected to the door frame 1, the wheel 42 is rotatably connected to the shell 41, the spring 44 is fixedly connected to the shell 41, the buffer plate 43 and the spring 44 are fixedly connected, the second slide bar 45 and the buffer plate 43 are fixedly connected, the second slide bar 45 and the shell 41 are slidably connected, the gear 46 and the second slide bar 45 are transmission-connected, the cam 47 and the gear 46 are fixedly connected, the gear 46 and the shell 41 are rotatably connected, the driven rod 48 and the cam 47 are slidably connected, and the brake block 49 and the driven rod 48 are fixedly connected.

[0055] The outer shell 41 can effectively prevent the wheel 42 from being hit by external objects during operation, thereby protecting the wheel 42. The buffer plate 43 and the spring 44 are fixedly connected to reduce the impact force of the walking mechanism 4 when it is hit or collides due to operational errors. The buffer plate 43 and the second slide bar 45 are fixedly connected to drive the second slide bar 45 to drive the gear 46 to rotate, thereby rotating the cam 47, so that the driven rod 48 connected thereto moves downward, and drives the brake block 49 to move downward and contact the track, generating friction, so that when the wheel 42 slides due to the collision of the walking mechanism 4, the friction force of the brake block 49 on the track reduces the sliding distance and stops.

[0056] like Fig. 9 and Fig.10 As shown, the cam 47 is provided with a sliding groove 471, the top of the driven rod 48 is spherical, the sliding groove 471 and the driven rod 48 are slidably connected, and the second sliding rod 45 is provided with gear teeth 451, which are meshed with the gear 46.

[0057] By means of the sliding groove 471 provided on the cam 47 and the spherical fit of the top end of the driven rod 48, the driven rod 48 is stuck on the cam 47 and moves with the rotation of the cam 47. By means of the gear teeth 451 provided on the second slide bar 45 and meshing with the gear 46, the second slide bar 45 can drive the gear 46 to rotate. By setting the number of gear teeth 451 to one-fourth of the gear 46, the gear 46 only rotates one-fourth, so that the cam 47 rotates just one-fourth, and the driven rod 48 drives the brake block 49 to contact the track.

[0058] Working principle: The gantry 1 provides fixed support, and the four-rope hoist 339 drives the wire rope to extend, so that the clamping unit 34 is loosened, and the clamping mechanism 3 is moved to the top of the distributed rail sleeper device through the sports car electric hoist 2, and the distributed rail sleeper device is positioned through the four positioning rods 324 of the positioning unit 32, and the block 333 is fixed by the arc plate 332. The fixing rod 334 is installed on the block 333, passing through the third through hole 3352 and the fourth through hole 3381, so that the guide plate 336 is fixed, and the block 333 and the slider are fixed. 335 and the second mounting plate 338 are connected through the through hole, so that the second mounting plate 338 moves with the first slide bar 331, and the four-rope hoist 339 controls the wire rope to make the first slide bar 331 rise and fall, driving the clamping unit 34 to be in a loose or clamping ready state under the action of the guide plate 336. When the limit unit 337 is lowered, it is clamped into the block 333 to prevent the slide bar from rising and keep the clamping unit 34 loose. When the clamping ready state needs to be restored, the limit unit 337 is lowered and drives the slider 335 to rise, leave the block 333, and restore In the clamping ready state, the four limit units 337 are evenly distributed to ensure the stability of the operation. In the clamping ready state, the clamp mechanism 3 is lifted as a whole by the sports car electric hoist 2, and the No. 1 connecting rod 341, the No. 2 connecting rod 342 and the No. 1 L-shaped claw hook 343 are hinged in sequence to form a connecting rod chain, so that the No. 1 L-shaped claw hook 343 of the clamping unit 34 hooks the distributed rail sleeper device, and the four corners are hooked by eight No. 1 L-shaped claw hooks 343 to ensure that the force of the distributed rail sleeper device is balanced during the lifting process, which enhances The overall stability of the lifting effectively reduces the shaking and swinging of the distributed rail sleeper device during the lifting process, and improves the safety and accuracy of the lifting. The walking mechanism 4 protects the wheel 42 from impact through the outer shell 41. When a collision occurs, it is connected to the spring 44 through the buffer plate 43 to reduce the impact force of the walking mechanism 4. The buffer plate 43 drives the second slide bar 45 to drive the gear 46 and the cam 47 to rotate, so that the driven rod 48 moves downward, and the brake block 49 contacts the track to generate friction, which effectively shortens the distance that the wheel 42 slides due to collision and stops.
