Description

Technical Field

[0001] The utility model belongs to the field of railway science and technology, and relates to a hydraulic replacement device for the chute wear plate of the side frame of a railway freight car bogie. Background Art

[0002] Wear plates are usually installed on railway vehicles or other mechanical equipment to reduce friction and wear and protect other components from damage. The main function of the wear plate is to reduce the direct impact and friction on other components through its own wear, thereby extending the service life of the entire system; it is crucial for ensuring the safe operation of railway vehicles. Especially during the train operation, when components such as brake beams are subjected to large alternating loads and impact forces, the role of the wear plate is particularly obvious. They absorb part of the impact force and reduce damage to other key components, thus ensuring the safety of railway transportation. In the maintenance operation of railway freight cars, due to the collision between the brake beam and the wear plate during the train operation, the chute wear plate of the side frame of the railway freight car is prone to cracks and needs to be replaced in time. Currently, the method of oxyacetylene cutting is used to disassemble the chute wear plate, but this method is easy to damage the side frame of the bogie.

[0003] Chinese Patent CN220922230U discloses a disassembling and assembling tool for the clamped chute wear plate of a railway freight car. This tool combines the structure of a threaded rod and a socket head, and uses an electric wrench to rotate the threaded rod to make the clamping jaws clamp the wear plate, causing the wear plate to deform and facilitating removal. However, this device has a complex structure, is easy to damage, and is not convenient to carry. Especially the setting of the threaded rod is extremely prone to wear and failure during actual operation. Summary of the Invention

[0004] To improve the above situation, the utility model provides a hydraulic replacement device for the chute wear plate of the side frame of a railway freight car bogie, which is small and convenient to carry, and has simple operation.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A hydraulic replacement device for the chute wear plate of the side frame of a railway freight car bogie, characterized in that it includes a main body bracket and an upper clamping jaw slidably connected to the main body bracket. Two limiting and strengthening plates are oppositely arranged at the upper end of the main body bracket. A lower clamping jaw is arranged at the lower end of the main body bracket. A positioning pin is arranged on the lower clamping jaw. A pair of strengthening ribs are oppositely arranged on the lower clamping jaw, and the strengthening ribs are fixedly connected to the main body bracket;

[0007] A pair of side plates are oppositely arranged on the left and right sides of the main body bracket. A sliding groove is formed on the side plate. Two sliding blocks which are slidably connected to the sliding groove are oppositely arranged on both sides of the upper claw. The upper claw is slidably connected to the side plate through the sliding groove. A pin hole is arranged on the upper claw, and the pin hole is correspondingly arranged with the positioning pin. A hydraulic jack is arranged above the upper claw.

[0008] The beneficial effects of the present utility model are as follows: By arranging the slidably connected upper claw, the device can cope with wear plates of different sizes of the sliding groove, and the lever principle is skillfully utilized to quickly and labor-savingly disassemble the wear plate of the sliding groove without damaging the side frame. By adopting a split structure, the structure is not only simple, small and convenient to carry, but also convenient to use.
