Assembly and disassembly tool for locomotive brake shoe

Abstract

The invention relates to the technical field of replacement of locomotive brake shoes, in particular to an assembly and disassembly tool for a locomotive brake shoe, which comprises a body and a support. The body comprises a hollow lever and a brake shoe hook which is of an 'F'-shaped structure, wherein the brake shoe hook which is of the 'F'-shaped structure is fixedly connected with the hollow lever. The support comprises a chain ring group and a hook body, one end of the chain ring group is welded with the hook body, the other end of the chain ring group is welded with the hollow lever, an adjusting chain ring is arranged on the upper portion of the chain ring group, a notch is arranged in the middle of the adjusting chain ring, antislip stop ends are arranged at two ends of the notch respectively, chain rings are mutually in series connection through the adjusting chain ring, the distance from a welding spot of the other end of the chain ring group with the hollow lever to the outermost end of the brake shoe hook which is of the 'F'-shaped structure ranges from 445mm to 455mm, and the distance from the welding spot of the other end of the chain ring group with the hollow lever to the other end of the hollow lever ranges from 740mm to 760mm.

Description

technical field [0001] The invention relates to the technical field of locomotive brake shoe replacement, in particular to a disassembly tool for the locomotive brake shoe. Background technique [0002] The brake shoe is a shoe-shaped brake block made of cast iron or other materials used for locomotives. When braking, it hugs the wheel tread and stops the wheel through friction. In this process, the braking device converts huge kinetic energy into heat energy and dissipates it in the atmosphere. The higher the train speed, the greater the thermal load on the wheels during braking. If cast iron brake shoes are used, the temperature can melt the brake shoes; even if more advanced synthetic brake shoes are used, the temperature will be as high as 400°C to 450°C. When the temperature of the wheel tread increases to a certain level, the tread will be worn, cracked or peeled off, which affects both the service life and driving safety.

AI Technical Summary

Problems solved by technology

[0004] Replacing locomotive brake shoes is laborious during locomotive maintenance, so it often happens that the brake shoes are not replaced after they are used to the limit

After the brake shoe is used to the limit, if it is not replaced, the brake shoe is easy to break when the locomotive implements emergency braking. Once the brake shoe breaks during operation, it is very easy to cause the brake shoe to fall off, damage the railway equipment or injure pedestrians, and may even be injured. cause train derailment

[0005] In the prior art, it takes 10 minutes to replace a brake shoe. If it is to replace the brake shoe of the second and fifth moving wheels of the locomotive, because the space there is narrow, the operation is inconvenient, and the force cannot be used, the time required will be longer, and it is easy to replace the brake shoe. dirty hands and body

When workers replace the brake shoes, their hands are covered with sludge and are relatively greasy, which is prone to work-related accidents

Due to the replacement of brake shoes, accidents of fingers being crushed or smashed frequently occur, which poses a major safety hazard
