Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-4 As shown, a traction machine maintenance device includes a base plate 1;

[0026] A through-hole mounting groove 2 is provided at the top center of the base plate 1. A movable component 5 is provided at the lower center of the interior of the base plate 1. The top of the movable component 5 penetrates the lower surface of the interior of the mounting groove 2, and connecting plates 7 are fixedly connected to both sides. A conversion component 6 is provided at the center of the interior of the connecting plate 7. The top of the conversion component 6 penetrates the top of the connecting plate 7, and a positioning plate 3 is provided. A through-hole placement groove 4 is provided at the front and rear of the top center of the base plate 1. During operation, the bottom of the base plate 1 is first placed against a flat ground to ensure the device is stable. After the device is stable, the necessary maintenance... The traction machine to be repaired is placed between two placement slots 4 on the top of the base plate 1. Then, the connecting plate 7 and the positioning plate 3 are moved by the moving component 5. After the two positioning plates 3 move, they can squeeze, clamp and position the traction machine to be repaired. This makes it easy for the device to position the traction machine to be repaired and prevents the traction machine from shifting during maintenance, thus avoiding accidental injury to maintenance workers. At the same time, the positioning plate 3 can be rotated by the conversion component 6, and the positioning plate 3 can change different surfaces to position according to the different shapes of the traction machine to be positioned. Therefore, the device can meet more usage needs and has strong practicality.

[0027] The inner lower surfaces of both placement slots 4 are arc-shaped, and the connecting plate 7 is T-shaped. The top of the connecting plate 7 fits into the bottom of the positioning plate 3, and the front and rear of the bottom of the connecting plate 7 fit into the top of the base plate 1. During operation, the arc-shaped placement slots 4 facilitate the placement of the traction machine, and the T-shaped connecting plate 7 facilitates installation with the base plate 1. At the same time, the fit between the connecting plate 7 and the positioning plate 3 allows the positioning plate 3 to rotate on the top of the connecting plate 7.

[0028] The positioning plate 3 has an arc-shaped positioning groove 302 on one side near the center of the mounting groove 2, and a positioning pad 303 is fixedly connected inside the positioning groove 302. The positioning plate 3 has a positioning groove 301 on one side away from the center of the mounting groove 2, and a positioning pad 304 is fixedly connected inside the positioning groove 301. During operation, the arc-shaped positioning groove 302 and the positioning pad 303 can squeeze, clamp and position the arc-shaped outer surface of the traction machine, and the flat outer surface of the traction machine can be squeezed, clamped and positioned by the flat positioning groove 301 and the positioning pad 304. At the same time, both the positioning pad 304 and the positioning pad 303 are made of rubber, which makes the anti-slip effect good.

[0029] The moving component 5 includes an inner groove 501 formed below the center of the base plate 1. A motor 504 is fixedly installed on the right side wall inside the inner groove 501. The output end of the motor 504 is fixedly connected to a bidirectional threaded rod 502, and the left end of the bidirectional threaded rod 502 is rotatably connected to the left side wall inside the inner groove 501. Both sides of the outer surface of the bidirectional threaded rod 502 are threaded with internal threaded sleeves 505. A vertically penetrating limiting groove 503 is formed at the center of the upper surface inside the inner groove 501. A limiting plate 506 is slidably connected inside the limiting groove 503, and the bottom of the limiting plate 506 is fixed to the top of the internal threaded sleeve 505. The top of the limiting plate 506 penetrates the lower surface of the mounting groove 2 and is fixedly connected to the bottom of the connecting plate 7. During operation, the motor 504 is connected to an external power source to energize the motor 504. After the motor 504 is energized, it drives the bidirectional threaded rod 502 to rotate. Then, after the bidirectional threaded rod 502 rotates, it drives the two internally threaded sleeves 505 that are threaded to it to move under the limitation of sliding in the limiting groove 503 through the limiting plate 506. After the movement of the internally threaded sleeves 505 drives the limiting plate 506 to move, the connecting plate 7 and the positioning plate 3 can move. Then, the two opposing positioning plates 3 move towards each other to squeeze, clamp and position the traction machine that needs to be repaired.

[0030] The conversion component 6 includes a groove 601 formed at the center of the top of the connecting plate 7. A slot 607 is formed at the center of the lower surface inside the groove 601. A rotating rod 602 is rotatably connected to the groove 601 via a bearing. The top end of the rotating rod 602 penetrates the top of the connecting plate 7 and is fixedly connected to the center of the bottom of the positioning plate 3. The bottom end of the rotating rod 602 is inserted into the slot 607, and a through-hole 608 is formed at the lower part of the slot. A through-slot 606 is formed on the side of the slot 607 away from the center of the mounting groove 2. A rod 604 is slidably connected inside the through-slot 606, and one end of the rod 604 near the center of the mounting groove 2 is inserted into the through-hole 608. A spring 605 is fitted on the outer surface of the rod 604 inside the through-slot 606. One end of the spring 605 near the center of the mounting groove 2 is fixedly connected to the outer surface of the insertion rod 604, and the other end of the spring 605 away from the center of the mounting groove 2 is fixedly connected to the inner wall of the through groove 606. During operation, the insertion rod 604 is moved by pulling it, and after moving, it moves out of the insertion hole 608. After the insertion rod 604 moves out of the insertion hole 608, it can be released from the limiting position of the rotating rod 602. While keeping the insertion rod 604 pulled, the positioning plate 3 can be rotated to make the positioning plate 3 rotate. Then, after the positioning plate 3 rotates 180 degrees, the insertion rod 604 is released. The insertion rod 604 moves under the action of the rebound force of the spring 605 that was squeezed by the previous pulling. Then, the insertion rod 604 moves and inserts into the insertion hole 608 to limit the position of the converted positioning plate 3 and keep the position of the converted positioning plate 3 stable.

[0031] One end of the insertion rod 604, located away from the center of the mounting groove 2, passes through the side of the connecting plate 7 and is fixedly connected to a handle plate 603; during operation, the handle plate 603 facilitates the movement of the insertion rod 604.
