Description

Technical Field

[0001] The present invention relates to the technical field of transportation devices, and in particular to a transportation device for a railway vehicle buffer. Background Art

[0002] Railway vehicle buffers are crucial components in the railway transportation system. They primarily mitigate the impact forces generated by traction, braking, and shunting during train operation, protecting the vehicle and track structure and improving the smoothness and safety of train operation. Railway vehicle buffers primarily include the following categories: spring buffers, friction buffers, rubber buffers, hydraulic buffers, and friction rubber buffers. During the production and processing of railway vehicle buffers, the buffer brackets are transported by conveyors to the installation site for assembly.

[0003] A Chinese patent document with publication number CN107116362A discloses a coupler buffer device assembly system and a method for using the same, the system comprising: a coupler frame conveyor line, a buffer conveyor line arranged adjacent to and parallel to the coupler frame conveyor line, a coupler frame lifting device installed below the conveying plane of the operating end of the coupler frame conveyor line, a slave plate support device fixedly arranged above the conveying plane of the operating end of the buffer conveyor line, a slave plate pushing device fixedly arranged above the conveying plane of the buffer conveyor line, a buffer pushing device fixedly arranged on the side of the operating end of the buffer conveyor line opposite to the coupler frame conveyor line, a compression device fixedly arranged above the conveying plane of the coupler frame conveyor line, and a coupler composition support device fixedly connected to the operating end of the coupler frame conveyor line; wherein, the coupler frame conveyor line is used to convey the coupler frame from the starting end of the coupler frame conveyor line to the operating end.

[0004] During operation, several hook tail frames to be assembled are lifted and placed sideways on the conveying plane at the starting end of the hook tail frame conveyor line in turn, with the lower plane of the hook tail frame facing upward and the head of the hook tail frame facing the operating end of the hook tail frame conveyor line; several buffers to be assembled are lifted and placed on the conveying plane at the starting end of the buffer conveyor line in turn, with the casting mark of the buffer box facing upward and the head of the buffer facing the operating end of the buffer conveyor line; several slave plates to be assembled are placed sideways in the slave plate basket in turn, and the slave plate basket is lifted into the mounting groove of the support frame, and the leakage hole of the slave plate basket is made to coincide with the leakage hole of the support frame; the hook tail frame conveyor line is started, and a hook tail frame is stepwise conveyed to the operating end of the hook tail frame conveyor line; the hook tail frame lifting device is started to lift the hook tail frame, so that the height of the bottom surface of the inner cavity of the hook tail frame is consistent with the height of the conveying plane of the buffer conveyor line; the slave plate pushing device is started to push the slave plate in the slave plate basket, so that a slave plate falls from the leakage hole of the slave plate basket and the leakage hole of the support frame to the operating end of the buffer conveyor line.

[0005] In the above technology, during the assembly process of the vehicle buffer, it is necessary to control the lifting equipment to place the buffer at the specified position on the buffer conveyor line so that the buffer can be installed. The lifting device is not convenient to adjust the position of the buffer, which makes the assembly efficiency of the buffer low. Summary of the Invention

[0006] The present invention provides a conveying device for a railway vehicle buffer, aiming to solve the problem of low buffer assembly efficiency in the related art.

[0007] A conveying device for a railway vehicle buffer of the present invention comprises: a frame, a conveying assembly and a clamping assembly;

[0008] The conveying assembly is arranged on the frame, the clamping assembly is arranged on the conveying assembly, and the conveying assembly is used to move the clamping assembly;

[0009] The cam is adapted to engage a first end of a second end of a guide rail and engage a second end of a guide rail, the cam being adapted to engage a first end of a second guide rail and the cam being adapted to engage a second end of a guide rail.

[0010] The effect is that the buffer bracket is placed on the clamping platform, and the conveying component realizes the conveying of the buffer bracket by driving the clamping platform to move. The side walls of the buffer bracket are respectively located between the clamping mechanism 1 and the clamping mechanism 3, and the clamping mechanism 2 and the clamping mechanism 4. By the clamping mechanism 1 and the clamping mechanism 3 being close to each other, the clamping mechanism 2 and the clamping mechanism 4 being close to each other, the clamping mechanism 1 and the clamping mechanism 3, and the clamping mechanism 2 and the clamping mechanism 4 are respectively against the side walls of the buffer bracket, thereby clamping the buffer bracket. By clamping the side walls on both sides of the buffer bracket, the buffer bracket is fixed, and the position of the buffer bracket can be conveniently adjusted, which can improve the assembly efficiency of the buffer.

[0011] Preferably, the conveying assembly includes a conveying chain, a driving shaft, a driven shaft and a driving member. The two conveying chains are distributed in parallel and spaced apart on the frame, and each conveying chain is rotatably engaged with the frame. The driving shaft and the driven shaft are rotatably engaged on the frame, and the driving shaft and the driven shaft are respectively clamped with the two ends of the conveying chain. The driving member is provided on the frame and connected to the driving shaft. The driving member can drive the conveying chain to rotate in a circular motion through the driving shaft, and the clamping platform is fixedly connected to the conveying chain.

[0012] The effect is that the conveyor chain is fixedly connected to the clamping platform. When the clamping platform is located above the conveyor chain, the buffer bracket can be placed on the clamping platform. The rotation of the conveyor chain can transport the clamping platform from one end of the frame to the other end of the frame, thereby realizing the transportation of the buffer bracket. When the clamping platform is located at the lower end of the conveyor chain, the clamping platform moves in the opposite direction and resets.

[0013] Preferably, a driving frame is provided on the frame body, and a plurality of partitions are provided on the driving frame, and the plurality of partitions form four channels. The sliding rod and the sliding seat are respectively connected to a shift rod through elastic member 1 and elastic member 2, and each shift rod can slide with the corresponding channel. Inclined plates are provided at both ends of each channel, and the shift rod can move along the corresponding inclined plates, thereby driving the clamping mechanism 1 and the clamping mechanism 3 to approach each other, and the clamping mechanism 2 and the clamping mechanism 4 to approach each other.

[0014] The effect is that the lever on each clamping mechanism moves along the corresponding inclined plate, thereby driving the corresponding clamping mechanism to move, and each clamping mechanism can be driven to move without an additional power source, thus saving energy.

[0015] Preferably, a rotating shaft is rotatably fitted on the sliding seat, and the rotating shaft is connected to the sliding seat through a first torsion spring. A rotating rod is provided at one end of the rotating shaft, and a rotating gear is provided at the other end thereof. The rotating gear can engage with the second elastic member, and the second elastic member is slidably fitted with the sliding seat. The rotating rod is an L-shaped rod, and the rotating rod can be against the side wall of the buffer bracket.

[0016] The effect is that when the clamping mechanism three and the clamping mechanism four are not in contact with the buffer bracket, the shift rod pushes the rotating gear through the elastic member two, and the first torsion spring is used to prevent the rotating shaft and the rotating gear from rotating, so that the rotating gear and the elastic member two move synchronously, and then drive the rotating shaft and the sliding seat to move, so that the clamping mechanism three and the clamping mechanism four are close to the buffer bracket. When the positioning block is against the buffer bracket, the elastic member two continues to move to rotate the rotating shaft, and drives the rotating rod to rotate around the rotating shaft until the rotating rod is against the buffer bracket, thereby increasing the fixed points of the buffer bracket and improving the clamping capacity.

[0017] Preferably, the positioning block is elastically connected to the sliding seat via an elastic member 3, and the positioning block can move up and down relative to the clamping platform.

[0018] The effect is that if the size of the buffer bracket is large, in most cases the buffer bracket can cover the positioning block, and the side wall of the buffer bracket is located between the positioning block and the rotating rod. In a small number of cases, the buffer bracket will be against the top of the positioning block and squeeze the positioning block downward. The elastic member three is compressed, and the top of the positioning block is flush with the upper surface of the clamping platform. At this time, the shift block drives the clamping mechanism three to move, which will cause the rotating rod to be against the outer wall of the buffer bracket.

[0019] Preferably, the cross-sections of the third slide groove and the fourth slide groove are T-shaped, the cross-section of the positioning block is the same as the cross-sections of the third slide groove and the fourth slide groove, and the positioning block can be abutted against the protrusion of the third slide groove or the fourth slide groove, thereby preventing the positioning block from detaching from the third slide groove or the fourth slide groove.

[0020] Preferably, a buffer block is provided on the rotating rod, and the buffer block is rotatably engaged with the rotating rod. The buffer block is provided with an arc surface end, and the arc surface end can be abutted against the side wall of the buffer bracket.

[0021] Preferably, the clamping platform is also rotatably matched with a rotating seat, and the rotating seat is connected to the clamping platform through a second torsion spring. A pressure plate is provided on the rotating seat, and an elastic member four is provided on the pressure plate. The elastic member four can pass through the rotating seat and slide with the rotating seat. A slider is provided on the elastic member four, and a guide rod is provided on the side wall of the driving frame. The slider can move along the guide rod, and the guide rod is in a broken line shape. When the slider moves along the guide rod, it can drive the rotating seat to rotate and pull the elastic member four, so that the pressure plate can move downward.

[0022] Preferably, a limit plate is provided on the rotating seat, and the limit plate is used to limit the rotation range of the rotating seat.

[0023] Preferably, a blowing device is provided at the bottom of the clamping platform, and an air inlet and an air outlet are provided on the clamping platform. The air inlet is connected to the blowing device, and a plurality of air outlets are located next to the air inlet and are spaced apart from the air inlet. The blowing device can blow air toward the buffer bracket through the air inlet.

[0024] By adopting the above technical solution, the beneficial effects of the present invention are:

[0025] A conveying device for a railway vehicle buffer of the present invention places the buffer bracket on a clamping platform when conveying the buffer bracket, and the conveying component conveys the buffer bracket by driving the clamping platform to move, and the side walls of the buffer bracket are respectively located between the clamping mechanism 1 and the clamping mechanism 3, and the clamping mechanism 2 and the clamping mechanism 4. By the clamping mechanism 1 and the clamping mechanism 3 being close to each other, the clamping mechanism 2 and the clamping mechanism 4 being close to each other, the clamping mechanism 1 and the clamping mechanism 3, and the clamping mechanism 2 and the clamping mechanism 4 are respectively against the side walls of the buffer bracket, thereby clamping the buffer bracket. By clamping the side walls on both sides of the buffer bracket, the buffer bracket is fixed, and the position of the buffer bracket can be conveniently adjusted, which can improve the assembly efficiency of the buffer.

[0055] The implementation principle of a conveying device for a railway vehicle buffer according to an embodiment of the present invention is as follows:

[0056] When transporting a smaller buffer bracket, the large diameter end of the buffer bracket is placed on the clamping platform 31, and the first positioning rod 321 and the second positioning rod are located inside the buffer bracket. When the clamping platform 31 moves from front to back, the first lever 324, the second lever, the third lever 348 and the fourth lever simultaneously abut against the corresponding first oblique rod 42 and move along the corresponding first oblique rod 42. When the first lever 324 moves along the first oblique rod 42 at the front end of the first channel 401, the first lever 324 pushes the first sliding rod 322 to move to the right through the elastic member 1 323, and the first positioning rod 321 and the first sliding rod 322 move to the right synchronously until the first positioning rod 321 abuts against the inner wall of the buffer bracket. At the same time, the second lever moves along the front end of the second channel 402. The first inclined rod 42 moves, and the second lever pushes the second sliding rod to move to the left through the elastic member 1 323 until the second positioning rod is against the inner wall of the buffer bracket, and the first positioning rod 321 and the second positioning rod support the buffer bracket from the inside. At the same time, the first positioning rod 321 and the second positioning rod are in double-point contact with the inner wall of the buffer bracket, and both ends of the first positioning rod 321 and the second positioning rod are against the inner wall of the buffer bracket, so that the axis of the buffer bracket is aligned with the center of the clamping platform 31, realizing convenient adjustment of the position of the buffer, and the first lever 324 and the second lever continue to move along the corresponding first inclined rod 42, so that the elastic member 1 323 is gradually compressed until the first lever 324 enters the first channel 401 and the second lever enters the second channel 402.

[0057] When the first and second clamping mechanisms 32 and 33 move, the third lever 348 moves along the first oblique rod 42 at the front end of the third channel 403, and the third lever 348 drives the second elastic member 347 to move leftward. The elastic force of the first torsion spring prevents the rotating gear 344 from rotating. The second elastic member 347 pushes the rotating shaft 343 to move leftward through the rotating gear 344. The first sliding seat 341 and the rotating shaft 343 move leftward synchronously until the first positioning block 342 abuts against the inner wall of the buffer bracket. At this time, the first positioning rod 321 and the first positioning block 342 can support the buffer. The right side wall of the frame is clamped, and when the first positioning block 342 is against the buffer bracket, the third shift rod 348 continues to move along the first oblique rod 42 at the front end of the third channel 403, and the elastic member 347 continues to move to the left, and drives the rotating gear 344 to rotate to overcome the elastic force of the first torsion spring, and the rotating shaft 343 rotates synchronously with the rotating gear 344, and drives the rotating rod 345 to rotate around the rotating shaft 343. During the rotation process, the buffer block 346 gradually approaches the right side wall of the buffer bracket and is against it, thereby increasing the fixing point of the buffer bracket and preventing the buffer bracket from shaking. The fourth lever moves along the first oblique lever 42 at the front end of the fourth channel 404. The movement principle of the clamping mechanism four 35 is the same as that of the clamping mechanism three 34. The clamping mechanism four 35 moves to the right. The second positioning rod and the second positioning block can clamp the right side wall of the buffer bracket. The buffer block 346 on the clamping mechanism four 35 is against the right side wall of the buffer bracket. The third lever 348 and the fourth lever continue to move along the corresponding first oblique lever 42. The corresponding elastic member two 347 is gradually compressed until the third lever 348 enters the third channel 403 and the fourth lever enters the fourth channel 404.

[0058] When the first lever 324, the second lever, the third lever 348 and the fourth lever enter the corresponding channels, the clamping mechanism one 32, the clamping mechanism two 33, the clamping mechanism three 34 and the clamping mechanism four 35 keep clamping the buffer bracket, the buffer bracket moves backward synchronously with the clamping platform 31, and the slider 55 gradually approaches the guide rod 57. When the slider 55 abuts against the guide rod 57, the guide rod 57 hinders the slider 55 from continuing to move forward, thereby driving the elastic piece four 54 to rotate. The rotating seat 51 rotates synchronously with the elastic piece four 54, until the elastic piece four 54 and the rotating seat 51 rotate to a vertical state. At this time, the limiting plate 56 abuts against the upper end surface of the clamping platform 31, thereby limiting the rotating seat 51 from continuing to rotate. The clamping platform 31 continues to move backward, and the slider 55 moves obliquely downward along the guide rod 57, thereby pulling the elastic piece four 54 to move downward, so that the pressing plate 52 moves downward. The spring of the elastic piece four 54 is compressed, until the pressing plate 52 abuts against the top end of the buffer bracket. The pressing plate 52 exerts downward pressure on the buffer bracket, further fixes the buffer bracket, and can also close the opening of the buffer bracket. Subsequently, the air blowing device 6 blows air into the buffer bracket through the air inlet 315. The air flow is vertically upward and abuts against the pressing plate 52, and then flows obliquely downward along the inner wall of the buffer bracket and is discharged from the air outlets 316 on both sides of the air inlet 315. The air flow can blow off the dust attached to the inner wall of the buffer bracket, and keep the inner wall of the buffer bracket clean.

[0059] When conveying a buffer bracket with a large volume, the first positioning block 342 and the second positioning block are located inside the buffer bracket or abut against the side wall of the buffer bracket. Under the action of its own gravity, the buffer bracket pushes the first positioning block 342 and the second positioning block to move downward, so that the upper surfaces of the first positioning block 342 and the second positioning block are aligned with the clamping platform 31. Then the clamping platform 31 moves from front to back. The first lever 324, the second lever, the third lever 348 and the fourth lever abut against and move along the corresponding first inclined rod 42 at the same time. The moving principles of the clamping mechanism one 32 and the clamping mechanism two 33 are the same as above. The first positioning rod 321 and the second positioning rod support the buffer bracket from the inside. If the inner wall of the buffer bracket is an arc structure, the first positioning rod 321 and the second positioning rod are in double-point contact with the buffer bracket. If the inner wall of the buffer bracket is a plane structure, the first positioning rod 321 and the second positioning rod are in surface contact with the buffer bracket. The first lever 324 and the second lever continue to move along the corresponding first inclined rod 42, so that the elastic piece one 323 is gradually compressed, until the first lever 324 enters the first channel 401 and the second lever enters the second channel 402.

[0060] The third shifting lever 348 drives the first sliding seat 341 to move left through the elastic member two 347 until the buffer block 346 on the clamping mechanism three 34 abuts against the right side wall of the buffer support, and the first positioning rod 321 and the buffer block 346 on the clamping mechanism three 34 can clamp the right side wall of the buffer support. Similarly, the second positioning rod and the buffer block 346 on the clamping mechanism four 35 can clamp the left side wall of the buffer support. The third shifting lever 348 and the fourth shifting lever continue to move along the corresponding first inclined rod 42, and the corresponding elastic member two 347 is gradually compressed until the third shifting lever 348 enters the third channel 403 and the fourth shifting lever enters the fourth channel 404. The clamping assembly 3 continues to move backward, and the first shifting lever 324, the second shifting lever, the third shifting lever 348 and the fourth shifting lever enter the corresponding channels, and the sliding block 55 gradually approaches the guide rod 57. When the sliding block 55 abuts against the guide rod 57, the guide rod 57 hinders the sliding block 55 from continuing to move forward, thereby driving the elastic member four 54 to rotate, and the rotating seat 51 rotates synchronously with the elastic member four 54 until the elastic member four 54 and the rotating seat 51 rotate to the vertical state. At this time, the limiting plate 56 abuts against the upper end surface of the clamping platform 31, thereby limiting the rotating seat 51 from continuing to rotate. The clamping platform 31 continues to move backward, and the sliding block 55 moves obliquely downward along the guide rod 57, thereby pulling the elastic member four 54 to move downward, so that the pressing plate 52 moves downward. The spring of the elastic member four 54 is compressed until the pressing plate 52 abuts against the top end of the buffer support. The pressing plate 52 exerts downward pressure on the buffer support, further fixes the buffer support, and can also close the opening of the buffer support. Subsequently, the hair dryer 6 blows air into the buffer support through the air inlet 315. The airflow flows vertically upward and abuts against the pressing plate 52, and then flows obliquely downward along the inner wall of the buffer support and is discharged from the air outlets 316 on both sides of the air inlet 315.
