[0016] Through the cooperation among the bottom plate, the support plate, the insulator, the debugging mechanism and the buffer mechanism, when the upper arm is stressed, the upper arm rotates clockwise on the lower arm through the pin shaft. The clockwise rotation of the upper arm makes the vertical rod move downward in the inner cavity of the sleeve through the round block. The vertical rod drives the curved rods on both sides of the sleeve plate to move downward. The curved rods make the top block move downward on the outer wall of the sleeve, so that the spring is compressed against the sleeve plate. On the contrary, the elastic force of the spring can offset the external force impact received by the upper arm and avoid damage between the upper arm and the lower arm, solving the problem that the existing support rod applicable to the maintenance, debugging and assembly of the pantograph of a rail vehicle is damaged due to excessive force on the upper arm and the lower arm after long-term use.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4, the present invention provides a technical solution: a support rod suitable for the maintenance, debugging and assembly of pantographs for rail vehicles, including a bottom plate 1. A support plate 3 is fixedly connected to the right top end of the bottom plate 1. A debugging mechanism 4 is installed above the left side of the bottom plate 1. The debugging mechanism 4 includes a threaded rod 401, a handle 402, a vertical block 403, a sleeve block 404, a slider 405, a chute 406, a connecting block 407, an inclined rod 408 and a lower arm 409. The left end of the threaded rod 401 is fixedly connected to the handle 402. The outer side of the threaded rod 401 is rotationally connected to the vertical block 403 through an internal bearing. Rotating the handle 402 drives the threaded rod 401 to rotate through the internal bearing in the vertical blocks 403 on both sides. The bottom end of the vertical block 403 is fixedly connected to the outer top end of the bottom plate 1. The left outer wall of the threaded rod 401 is threadedly connected to the sleeve block 404. The bottom end of the sleeve block 404 is fixedly connected to the slider 405. The slider 405 is slidably clamped with the chute 406. The chute 406 is opened above the left side of the bottom plate 1. When the threaded rod 401 rotates, the sleeve block 404 slides left and right on the chute 406 on the bottom plate 1 through the slider 405, and the chute 406 prevents the slider 405 from derailing. The top end of the sleeve block 404 is fixedly connected to the connecting block 407. The front end of the connecting block 407 is rotationally connected to the inclined rod 408 through a pin shaft. The upper side of the inclined rod 408 is rotationally connected to the lower arm 409 through a pin shaft. The lower side of the lower arm 409 is rotationally connected to the support plate 3 through a pin shaft. The sleeve block 404 drives the connecting block 407 to move left and right, and through the linkage of the inclined rod 408, the lower arm 409 rotates and is debugged through the pin shaft on the support plate 3. The outer wall of the handle 402 is processed with grinding lines to increase the rotational friction. The slider 405 and the chute 406 form a sliding structure, and the slider 405 slides left and right in the chute 406.

[0024] An insulator 2 is installed at the left bottom end of the bottom plate 1.

[0025] Above the lower arm 409, a buffer mechanism 5 is installed. The buffer mechanism 5 includes an upper arm 501, a round block 502, a vertical rod 503, a sleeve 504, a connecting plate 505, a sleeve plate 506, a curved rod 507, a top block 508, a spring 509, and a top plate 510. The upper arm 501 is rotationally connected to the lower arm 409 through a pin shaft. The upper arm 501 rotates on the lower arm 409 through a pin shaft. A round block 502 is fixedly connected to the bottom end of the upper arm 501. The round block 502 is rotationally connected to a vertical rod 503 through a pin shaft. The outer wall of the lower part of the vertical rod 503 is in interference fit with a sleeve 504. When the upper arm 501 rotates clockwise, the vertical rod 503 moves downward in the inner cavity of the sleeve 504 through the round block 502. The vertical rod 503 is made of hard rubber material to increase the friction with the sleeve 504 and achieve a damping effect. The sleeve 504 is rotationally connected to the connecting plate 505 through a pin shaft. The sleeve 504 moves on the connecting plate 505 through a pin shaft. The bottom end of the connecting plate 505 is fixedly connected to the top end of the lower arm 409. A sleeve plate 506 is fixedly connected to the outer wall of the vertical rod 503. A curved rod 507 is fixedly connected to the outer wall of the sleeve plate 506. A top block 508 is fixedly connected to the lower part of the curved rod 507. The inner wall of the middle of the top block 508 is in clearance fit with the outer wall of the sleeve 504. A spring 509 is fixedly connected to the bottom end of the top block 508. A top plate 510 is fixedly connected to the bottom end of the spring 509. The inner wall of the spring 509 is in clearance fit with the outer wall of the sleeve 504. The inner wall of the top plate 510 is fixedly connected to the outer wall of the sleeve 504. The vertical rod 503 drives the curved rods 507 on both sides of the sleeve plate 506 to move downward. The curved rod 507 makes the top block 508 move downward on the outer wall of the sleeve 504, causing the spring 509 to be compressed against the top plate 510. Conversely, the elasticity of the spring 509 can offset the external force impact received by the upper arm 501 and prevent damage between the upper arm 501 and the lower arm 409. The curved rods 507 are symmetrically arranged with respect to the vertical rod 503 to ensure stable up and down movement of the vertical rod 503.

[0026] When using this support rod applicable to the maintenance, debugging, and assembly of pantographs for rail vehicles, first install the entire device at the designated position. Manually rotate the handle 402 to drive the threaded rod 401 to rotate through the internal bearing in the vertical blocks 403 on both sides. When the threaded rod 401 rotates, the sleeve block 404 slides left and right in the chute 406 on the bottom plate 1 through the slider 405. The sleeve block 404 drives the connecting block 407 to move left and right, and through the linkage of the inclined rod 408, the lower arm 409 is rotated and debugged through the pin shaft on the support plate 3. When the upper arm 501 is stressed, the upper arm 501 rotates clockwise on the lower arm 409 through the pin shaft. When the upper arm 501 rotates clockwise, the vertical rod 503 moves downward in the inner cavity of the sleeve 504 through the round block 502. The vertical rod 503 drives the curved rods 507 on both sides of the sleeve plate 506 to move downward. The curved rod 507 makes the top block 508 move downward on the outer wall of the sleeve 504, causing the spring 509 to be compressed against the top plate 510. Conversely, the elasticity of the spring 509 can offset the external force impact received by the upper arm 501 and prevent damage between the upper arm 501 and the lower arm 409.
