Description

Technical Field

[0001] This invention relates to the field of mountain rail technology, specifically to a passively adjustable mountain rack railway gear tooth entry device. Background Technology

[0002] As a special mode of transportation adapted to steep gradients and complex road conditions, the stability of the meshing of gears and racks in the ground gear railway is directly related to driving safety and passenger comfort, and is a core technical link to ensure the operation of the line.

[0003] Currently, the gear engagement devices in existing mountain rack railways generally adopt an active drive mode, that is, a separate drive mechanism drives the gear to rotate to achieve meshing with the rack. Although this type of device can complete the basic gear engagement function, it has significant drawbacks: on the one hand, the addition of an active drive mechanism leads to a complex device structure and high manufacturing costs, and the limited maintenance space and harsh operating conditions in mountainous environments further increase the difficulty and cost of equipment maintenance; on the other hand, traditional gear engagement structures lack the ability to adaptively adjust the distance between the gear and rack, and rigid impacts are easily generated at the moment of meshing, which not only accelerates the wear of the gears and racks and shortens the service life of components, but also affects the smoothness of train operation.

[0004] Crucially, mountain rack railways are characterized by large gradients and tracks that are susceptible to vibration. Existing devices are difficult to adapt to such complex working conditions. The speed control of active drive is easily affected by vibration, and the fixed spacing structure cannot compensate for track installation errors or gear misalignment caused by vibration. Ultimately, this makes it difficult to guarantee the stability of gear meshing, which has become a prominent problem restricting the safe and efficient operation of mountain rack railways.

[0005] Therefore, developing a toothed gear device that does not require an additional active drive mechanism, has adaptive spacing adjustment capability, and can adapt to complex mountain working conditions, in order to solve the problems of complex structure, difficult maintenance, large meshing impact, and insufficient stability in the existing technology, has become an urgent need in the field of mountain rack railway technology.

[0025] This invention provides a passively adjustable tooth entry device for mountain rack railways, which has the following beneficial effects:

[0026] 1. This invention uses the output end of an electric actuator to drive a sliding block to move, causing the electric actuator to slide within a support plate and a support plate, and push the sliding block to slide on the inner wall of the support plate. This causes one end of the sliding block to push a rotating block to move, making the rotating block rotate on a fixed plate, and pushing the fixed plate to move, which in turn causes the rotating shaft to rotate on the support plate. This adjusts the angle of the V-shaped rubber plate. When the vehicle moves, the gear contacts the V-shaped rubber plate, and the V-shaped structure on the V-shaped rubber plate blocks the gear teeth, causing the gear to rotate. This achieves the effect of passively rotating the gear when the vehicle moves.

[0027] 2. This invention rotates the fixing bolt on the sliding sleeve and uses threads to make the fixing block slide out from between the engaging blocks, releasing the limitation on the sliding sleeve. By pushing the second support block, the sliding sleeve slides on the first limiting block, and the limiting plate moves, adjusting the position of the limiting plate. When the vehicle moves along the track, the wheel contacts the limiting plate, causing the wheel to move along the limiting plate, thereby adjusting the gear position. Then, by rotating the fixing bolt, the fixing block slides within the first limiting block and engages with the engaging block, achieving the effect of fixing the sliding sleeve.

[0028] 3. In this invention, the gear contacts the guide wheel, and the guide wheel pushes the limiting frame to drive the sliding rod to slide inside the threaded sleeve. The limiting frame also drives the limiting block two to slide inside the support frame one. The limiting frame is moved by the spring one, which causes the guide wheel to push the gear, so that the gear position is finely adjusted. By rotating the threaded sleeve, it moves inside the support frame one under the action of the thread, and squeezes the spring one to achieve the effect of adjusting the preload.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a passively adjustable mountain rack railway tooth entry device, including a fixed frame 1, a track 2 symmetrically fixedly connected to the upper surface of the fixed frame 1, a support block 4 fixedly connected to the upper surface of the fixed frame 1, and a rack 3 fixedly connected to the upper surface of the support block 4.

[0041] The guide mechanism 5 is mounted on the upper surface of the fixed frame 1 and is used to drive the gear to rotate;

[0042] The guiding mechanism 5 includes a support plate 1 501, a support plate 2 503 fixedly connected to the upper surface of the support plate 1 501, a rotating shaft 506 rotatably connected to the inner wall of the support plate 2 503, a fixing plate 1 502 fixedly connected to the outer wall of the rotating shaft 506, a V-shaped rubber plate 504 slidably connected to the upper surface of the fixing plate 1 502, a pressure plate 5011 provided on the side of the V-shaped rubber plate 504, a threaded rod 5010 provided on the pressure plate 5011, and a threaded hole provided on the fixing plate 1 502, through which the threaded rod 5010 passes. The fixed plate 502 is connected to the threaded hole. The outer wall of the support plate 503 is fixedly connected to the electric actuator 508. The output end of the electric actuator 508 is fixedly connected to the sliding block 509. The outer wall of the sliding block 509 is slidably connected to the sliding block 507. One end of the sliding block 507 is fixedly connected to the rotating block 505. The outer wall of the rotating block 505 is rotatably connected to the lower surface of the fixed plate 502. The outer wall of the sliding block 507 is slidably connected to the outer wall of the support plate 503. The outer wall of the support plate 501 is provided with a damping component.

[0043] Specifically, the output end of the electric actuator 508 drives the sliding block 509 to move, causing the electric actuator 508 to slide within the support plate 501 and the support plate 503, and pushes the sliding block 507 to slide on the inner wall of the support plate 503. This causes one end of the sliding block 507 to push the rotating block 505 to move, causing the rotating block 505 to rotate on the fixed plate 502, and pushing the fixed plate 502 to move and drive the rotating shaft 506 to rotate on the support plate 503, thereby adjusting the angle of the V-shaped rubber plate 504.

[0044] When the vehicle moves, the gear contacts the V-shaped rubber plate 504. The V-shaped structure on the V-shaped rubber plate 504 blocks the gear tooth surface, causing the gear to rotate. This achieves the effect of passively rotating the gear while the vehicle is moving. The gear moves on the V-shaped rubber plate 504. When the gear moves, it presses down on the V-shaped rubber plate 504, which drives the fixed plate 1 502 to move. This causes the support plate 2 503 and support plate 1 501 to move. The support plate 1 501 then drives the fixed plate 2 14 and support frame 3 15 to move, thereby transmitting the generated vibration to the damper 12. The damper 12 absorbs the vibration, thus reducing the impact generated by the gear movement.

[0045] By rotating the threaded rod 5010 on the pressure plate 5011, and moving the threaded rod 5010 on the fixed plate 502 through the thread, the pressure plate 5011 is moved at the same time, releasing the limit on the V-shaped rubber plate 504, and then pulling the V-shaped rubber plate 504 to slide inside the fixed plate 502, thereby removing the V-shaped rubber plate 504 and replacing the worn V-shaped rubber plate 504. By rotating the threaded rod 5010 to move the pressure plate 5011 to squeeze the V-shaped rubber plate 504, the effect of fixing the V-shaped rubber plate 504 is achieved.

[0046] The limiting mechanism 7 is installed at the position of the fixed frame 1 near the track 2 and is used to limit the wheel. The limiting mechanism 7 includes a limiting block 704, the lower surface of the limiting block 704 is fixedly connected to the upper surface of the fixed frame 1, the outer wall of the limiting block 704 is slidably connected to a sliding sleeve 703, the upper surface of the sliding sleeve 703 is fixedly connected to a support block 702, the outer wall of the support block 702 is fixedly connected to a limiting plate 701, the inner side of the sliding sleeve 703 is rotatably connected to a fixing bolt 705, the outer wall of the fixing bolt 705 is threadedly connected to a fixing block 706, the outer wall of the fixing block 706 is slidably connected to a locking block 707, and the outer wall of the locking block 707 is fixedly connected to the inner wall of the limiting block 704.

[0047] Specifically, by rotating the fixing bolt 705 on the sliding sleeve 703, and by using the thread to make the fixing block 706 slide out from between the engaging blocks 707, the limitation on the sliding sleeve 703 is released. By pushing the second support block 702, the sliding sleeve 703 slides on the first limiting block 704, and the limiting plate 701 moves, adjusting the position of the limiting plate 701. When the vehicle moves along the track 2, the wheel contacts the limiting plate 701, causing the wheel to move along the limiting plate 701, thereby adjusting the gear position. Then, by rotating the fixing bolt 705, the fixing block 706 slides in the first limiting block 704 and engages with the engaging block 707, achieving the effect of fixing the sliding sleeve 703.

[0048] The spacing adjustment mechanism 8 is installed on the upper surface of the fixed frame 1 and is used to adjust the position of the gear. The spacing adjustment mechanism 8 includes a support frame 801, the lower surface of which is fixedly connected to the upper surface of the fixed frame 1. A limit block 807 is slidably connected inside the support frame 801. A limit frame 802 is fixedly connected to the upper surface of the limit block 807. A guide wheel 803 is rotatably connected inside the limit frame 802. A sliding rod 806 is fixedly connected to the outer wall of the limit frame 802. A threaded sleeve 805 is fixedly connected to the outer wall of the sliding rod 806. The outer wall of the sliding rod 806 is threadedly connected to the inside of the support frame 801. A spring 804 is fixedly connected to the outer wall of the limit frame 802. One end of the spring 804 is rotatably connected to one end of the threaded sleeve 805.

[0049] Specifically, after passing through the V-shaped rubber plate 504, the gear contacts the guide wheel 803, causing the guide wheel 803 to push the limiting frame 802, which in turn drives the sliding rod 806 to slide inside the threaded sleeve 805. This causes the limiting frame 802 to drive the limiting block 807 to slide inside the support frame 801. The spring 804 pushes the limiting frame 802 to move, causing the guide wheel 803 to push the gear, thus fine-tuning the gear position. By rotating the threaded sleeve 805, the gear moves within the support frame 801 under the action of the thread, and compresses the spring 804 to achieve the effect of adjusting the preload. After passing through the guide wheel 803, the gear contacts the roller 27, causing the gear to mesh between multiple rollers 27 and move forward to contact the rack 3.

[0050] Multiple limiting rods 19 are fixedly connected to the inner bottom of the fixed frame 1. Support plates 3 18 and 4 28 are slidably connected to the outer walls of the multiple limiting rods 19. Electric actuators 26 and 3 29 are fixedly connected to the inner bottom of the fixed frame 1. Connecting frames 3 25 are fixedly connected to the output ends of electric actuators 26 and 3 29. Connecting rods 24 are rotatably connected inside connecting frames 3 25. Connecting frame 23 is rotatably connected to one end of connecting rod 24. The upper surface of connecting frame 23 is fixedly connected to support plates 3 18 and 4 28. The lower surface of support plate 4 28, support plate 3 18 and support plate 4 28 are slidably connected to limit rod 22. One end of limit rod 22 is fixedly connected to protective sleeve 20. The upper surface of protective sleeve 20 is fixedly connected to connecting frame 6. The inner wall of protective sleeve 20 is fixedly connected to spring 21. One end of multiple springs 21 is fixedly connected to the upper surface of support plate 4 28 and support plate 3 18 respectively. The outer wall of multiple connecting frames 6 is fixedly connected to support plate 501 and slot frame 9 respectively. The inside of slot frame 9 is rotatably connected to roller 27.

[0051] Specifically, the output end of the electric actuator 26 pushes the connecting frame 25 to move, which in turn pushes the connecting rod 24 to move and rotate on the connecting frame 23. Simultaneously, it pushes the support plate 18 to slide on the limiting rod 19, thereby causing the support plate 18 to push the spring 21 to move. The spring 21 then pushes the protective sleeve 20 to move the connecting frame 6, which in turn moves the support plate 501, thus adjusting the height of the support plate 501. The electric actuator 29 pushes the connecting frame 25 to move, which in turn pushes the connecting rod 24 to rotate on the connecting frame 23. This also pushes the support plate 28 to move in the same way, causing it to slide on the limiting rod 19. The support plate 28 then pushes the spring 21 to move, which in turn pushes the protective sleeve 20 to move the connecting frame 6. This, in turn, causes the connecting frame 6 to move the slot frame 9, thus achieving the effect of adjusting the height of the roller 27.

[0052] Rotation sensor 10 and pressure sensor 13 are fixedly connected to the upper surface of the fixed frame 1, rotation sensor 2 16 is fixedly connected to the upper surface of the limiting frame 802, and pressure sensor 2 17 is fixedly connected to the upper surface of the support frame 1 801.

[0053] Specifically, the rotation speed of the gear is detected by rotation sensor 10 and rotation sensor 26, and the pressure when the gear passes by is detected by pressure sensor 13 and pressure sensor 27.

[0054] Please see the appendix Figure 9 The tooth-feeding device of the present invention also includes a control system, which includes a controller, a data acquisition unit and an execution unit;

[0055] The data acquisition unit includes rotation sensor 10, rotation sensor 2 16, pressure sensor 13 and pressure sensor 2 17, which are used to monitor the rotation speed and pressure data of the gear in real time and transmit them to the controller.

[0056] The actuation unit includes an electric actuator 508 for adjusting the angle of the V-shaped rubber plate 504, an electric actuator 26 for adjusting the height of the support plate 501, and an electric actuator 29 for adjusting the height of the slot frame 9.

[0057] The controller is electrically connected to the data acquisition unit and the execution unit respectively. The controller is configured to: receive rotational speed data and control the extension and retraction of electric push rod 508 according to the rotational speed data to change the tilt angle of V-shaped rubber plate 504; receive pressure data and control the extension and retraction of electric push rod 26 and electric push rod 29 according to the pressure data to compensate for the vertical height adjustment of support plate 501 and slot frame 9.

[0058] Working principle: First, the fixing bolt 705 is rotated on the sliding sleeve 703, and the fixing block 706 slides out from between the engaging blocks 707 through the thread, releasing the limitation on the sliding sleeve 703. By pushing the second support block 702, the sliding sleeve 703 slides on the first limiting block 704, and the limiting plate 701 moves, adjusting the position of the limiting plate 701. When the vehicle moves along the track 2, the wheel contacts the limiting plate 701, causing the wheel to move along the limiting plate 701, thereby adjusting the gear position. Then, by rotating the fixing bolt 705, the fixing block 706 slides in the first limiting block 704 and engages with the engaging block 707, achieving the effect of fixing the sliding sleeve 703.

[0059] The output end of the electric actuator 26 pushes the connecting frame 25 to move, and the connecting rod 24 to move and rotate on the connecting frame 23. At the same time, it pushes the support plate 318 to slide on the limit rod 19, which in turn pushes the spring 21 to move. The spring 21 pushes the protective sleeve 20 to move the connecting frame 6, and the connecting frame 6 to move the support plate 501, thereby adjusting the height of the support plate 501. The output end of the electric actuator 508 drives the sliding block 509 to move, so that the electric actuator 508 slides between the support plate 501 and the support plate 203, and pushes the sliding block 507 to slide on the inner wall of the support plate 203. This causes one end of the sliding block 507 to push the rotating block 505 to move, so that the rotating block 505 rotates on the fixed plate 502, and pushes the fixed plate 502 to move, causing the rotating shaft 506 to rotate on the support plate 203, thereby adjusting the angle of the V-shaped rubber plate 504.

[0060] When the vehicle moves, the gear contacts the V-shaped rubber plate 504. The V-shaped structure on the V-shaped rubber plate 504 blocks the gear tooth surface, causing the gear to rotate. This achieves the effect of passively rotating the gear while the vehicle is moving. The gear moves on the V-shaped rubber plate 504. When the gear moves, it presses down on the V-shaped rubber plate 504, which drives the fixed plate 1 502 to move. This causes the support plate 2 503 and support plate 1 501 to move. The support plate 1 501 then drives the fixed plate 2 14 and support frame 3 15 to move, thereby transmitting the generated vibration to the damper 12. The damper 12 absorbs the vibration, thus reducing the impact generated by the gear movement.

[0061] By rotating the threaded rod 5010 on the pressure plate 5011, and moving the threaded rod 5010 on the fixed plate 502 through the thread, the pressure plate 5011 is moved at the same time, releasing the limit on the V-shaped rubber plate 504. Then, the V-shaped rubber plate 504 is pulled to slide inside the fixed plate 502, thereby removing the V-shaped rubber plate 504 and replacing the worn V-shaped rubber plate 504. By rotating the threaded rod 5010 to move the pressure plate 5011 to squeeze the V-shaped rubber plate 504, the effect of fixing the V-shaped rubber plate 504 is achieved.

[0062] After passing through the V-shaped rubber plate 504, the gear contacts the guide wheel 803, causing the guide wheel 803 to push the limit frame 802, which in turn drives the sliding rod 806 to slide inside the threaded sleeve 805. This causes the limit frame 802 to drive the second limit block 807 to slide inside the first support frame 801. The first spring 804 pushes the limit frame 802 to move, causing the guide wheel 803 to push the gear, thus finely adjusting the gear position. By rotating the threaded sleeve 805, the gear moves within the first support frame 801 under the action of the thread, and compresses the first spring 804 to achieve the effect of adjusting the preload. After passing through the guide wheel 803, the gear contacts the roller 27, causing the gear to mesh between multiple rollers 27 and move forward to contact the rack 3.

[0063] The electric actuator 29 pushes the connecting frame 25 to move, causing the connecting frame 25 to push the connecting rod 24 to rotate on the connecting frame 23, and pushes the support plate 28 to move in the same way, causing the support plate 28 to slide on the limit rod 19, causing the support plate 28 to push the spring 21 to move, and the spring 21 to push the protective sleeve 20 to move the connecting frame 6, thereby causing the connecting frame 6 to move the slot frame 9, achieving the effect of adjusting the height of the roller 27.
