Description

Technical Field

[0001] This utility model relates to the field of train maintenance equipment technology, and in particular to a tooling for replacing train unit brakes. Background Technology

[0002] The unit brake is a key actuator in the braking system of railway vehicles. It amplifies the braking force generated by the brake cylinder and distributes it evenly to each wheel, causing the vehicle to slow down or stop and ensuring train operation safety. Replacing the unit brake is a common and important task during train maintenance. Currently, auxiliary tooling is required when disassembling and replacing unit brakes. Using this tooling for lifting and supporting the unit brake saves manpower and facilitates operation.

[0003] However, while existing auxiliary tooling can lift unit brakes, it cannot rotate, which means the position of the hook relative to the entire tooling cannot be adjusted. This results in poor flexibility and adaptability. Furthermore, during the lifting of the unit brake, the weight of the unit brake can cause occasional swaying. Since the tooling lacks a limit and anti-sway structure, this affects the rapid lifting and lowering of the unit brake, leading to poor operational stability. The swaying unit brake can also easily collide with the tooling personnel, causing injury, thus posing a safety hazard. Utility Model Content

[0004] The main purpose of this utility model is to provide a tooling for replacing train unit brakes, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a train unit brake replacement fixture includes a base 1, an adjusting rod 2 on the base 1, and a placement platform 3 connected to the upper end of the adjusting rod 2. A fixing column 4 is provided on the placement platform 3, a rotating component 5 is installed on the upper end of the fixing column 4, and a mounting frame 6 is connected to the rotating component 5. A limiting component 7 is provided on the mounting frame 6, and a motor 8 is fixed on the mounting frame 6. A winding drum 9 is provided on the inner side of the mounting frame 6, and a lifting rope 10 is provided on the winding drum 9. A hook 11 is provided at the lower end of the lifting rope 10.

[0019] The end of the adjusting rod 2 is provided with a fixed shaft 12, and an adjusting seat 13 is rotatably connected to the fixed shaft 12. The base 1 is provided with a fixed seat 14, and the fixed seat 14 is provided with a second servo motor 15 and an adjusting screw 16. The adjusting screw 16 is threadedly connected to the adjusting seat 13.

[0020] When replacing the unit brake on a train, the train is parked in the maintenance workshop. The tooling is moved to the vicinity of the train using the wheels at the lower end of the base 1. After starting the second servo motor 15 at the fixed seat 14, the second servo motor 15 rotates the adjusting screw 16, thereby driving the adjusting seat 13 to move along the fixed shaft 12. This causes one end of the adjusting rod 2 to move on the base 1 and the placement platform 3, thus changing the height of the placement platform 3. During this process, the adjusting seat 13 and the fixed shaft 12 rotate relative to each other without affecting the normal movement of the adjusting rod 2. After the height of the placement platform 3 is adjusted, the rotating assembly 5 is started to rotate the mounting frame 6, the winding drum 9, the lifting rope 10, and the hook 11 to the side of the placement platform 3. After starting the motor 8, the winding drum 9 rotates on the mounting frame 6 to wind up and unwind the lifting rope 10. The hook 11 is moved to the appropriate height and then hooked onto the unit brake. Then, the unit brake is disassembled.

[0021] After the unit brake is disassembled, it is lifted by the hoisting rope 10 and hook 11. Then, the rotating assembly 5 is started to move the unit brake to the placement platform 3. The motor 8 is started again to release the rope and place the unit brake on the placement platform 3. Then, the unit brake is moved using tooling. When reinstalling the unit brake later, the tooling is used for moving, and then it is lifted and installed.

[0022] According to the above implementation scheme, the rotating assembly 5 includes a rotating rod 501, a mounting plate 502, a driven gear 503, a first servo motor 504, and a driving gear 505. The rotating rod 501 and the mounting plate 502 are fixedly connected, and the rotating rod 501 is rotatably mounted on the fixed column 4. The driven gear 503 is mounted on the lower end of the rotating rod 501. The first servo motor 504 is mounted on the mounting plate 502. The driving gear 505 is connected to the output shaft of the first servo motor 504, and the driving gear 505 is meshed with the driven gear 503.

[0023] When using the rotating component 5, after starting the first servo motor 504 on the mounting plate 502, the driving gear 505 rotates, causing the driven gear 503 to rotate. The driven gear 503 then causes the rotating rod 501 to rotate on the fixed column 4, thereby changing the position of the structure at the mounting bracket 6 and improving the flexibility and adaptability of use.

[0024] According to the above implementation scheme, the limiting component 7 includes a cylinder 701, a lifting rod 702, a connecting rod 703, a top plate 704, a micro servo motor 705, and an adjusting screw 706. The cylinder 701 is fixed on the mounting frame 6. The lifting rod 702 is fixedly connected to the connecting rod 703 and passes through the mounting frame 6. The top plate 704 is fixed to the upper end of the lifting rod 702. The micro servo motor 705 is mounted on the top plate 704. The upper end of the adjusting screw 706 is connected to the micro servo motor 705, and the lower end of the adjusting screw 706 is connected to the cylinder 701. The limiting component 7 also includes a strip hole 707, a limiting block 708, a round hole 709, and a baffle 710. The strip hole 707 is formed on the connecting rod 703, the round hole 709 is formed on the limiting block 708, and the limiting block 708 is disposed in the strip hole 707. The baffle 710 is mounted on the limiting block 708.

[0025] When lifting or lowering the unit brake, the lifting rope 10 moves within the circular hole 709. Due to the limitation of the limiting block 708, the lifting rope 10 does not sway significantly, ensuring stability during use. As the lifting rope 10 is wound or unwound, its position on the winding drum 9 changes. The limiting block 708 moves along the strip hole 707 on the connecting rod 703 via the baffle 710, providing both limiting stability and adaptive movement to ensure the normal movement of the lifting rope 10. Simultaneously, the height of the hook 11 changes during the movement of the lifting rope 10. To ensure relative stability, the micro servo motor 705 on the top plate 704 can be activated, and the adjusting screw 706 can be rotated to raise or lower relative to the cylinder 701. This causes the lifting rod 702, along with the connecting rod 703 and the limiting block 708, to rise or fall, adapting to the height of the hook 11 without affecting its lifting and lowering, thus ensuring optimal performance.

[0026] It should be noted that the position of the hook 11 can be adjusted by the rotating component 5, which makes it easy to rotate the hook 11 to one side of the base 1 for operation during lifting. After the unit brake is disassembled, it can be lifted and rotated to the top of the placement platform 3, and then the unit brake can be lowered for placement. The structure is simple, and the flexibility and adaptability are high. The limiting component 7 is set on the mounting frame 6 to limit the lifting rope 10, so as to avoid large swaying during the lifting and lowering of the unit brake, ensuring the stability of operation, and preventing the swaying unit brake from hitting the tooling personnel, thus improving the safety of operation. The limiting block 708 can move along the strip hole 707 to adapt to the position of the lifting rope 10. The lifting rod 702 and the connecting rod 703 can be raised and lowered and can be adjusted according to the position of the hook 11, ensuring the stability of the lifting rope 10 without affecting the raising and lowering of the hook 11.

[0027] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
