Gear shaft fixing and repairing device

Abstract

The invention relates to a gear shaft fixing and repairing device, the device comprises a supporting frame, a positioning stop device and a connecting device, wherein the supporting frame comprises asupporting base, fixing support frames and supporting brackets, the fixing support frames are connected with the supporting base, the supporting brackets are arranged on the fixing support frames, thepositioning stop device comprises an adjustor, a base plate, a connecting block and a positioner, the adjustor and the positioner are both installed on the base plate, the connecting block is arranged between the adjustor and the positioner, the connecting device comprises an adjusting device, a positioning rod and a connecting rod, the adjusting device is connected with the supporting frame, thepositioning rod is arranged on the adjusting device, one end of the connecting rod is connected with the positioning rod, and the other end of the connecting rod is connected with the adjuster on thepositioning stop device. The gear shaft fixing and repairing device is high in adaptability, capable of achieving rapid positioning, convenient to adjust and use, good in fixing effect, capable of improving the gear shaft repairing operation efficiency and the site utilization rate, safe, reliable and capable of avoiding safety accidents caused by stability damage in the repairing operation process.

Description

technical field [0001] The invention relates to the technical field of gear shaft repair, more specifically, it relates to a fixed repair device for gear shafts. Background technique [0002] A gear shaft refers to a mechanical part that supports a rotating part and turns with it to transmit motion, torque or bending moment. Generally, it is in the shape of a metal round rod, and each segment can have different diameters. The parts that make rotary motion in the machine are mounted on the shaft. [0003] For the gear shaft spare parts that need to be repaired offline, the first thing to do is to place the gear shaft to be repaired stably, so as to avoid personal injury or damage to the spare parts to be repaired due to the stability of the gear shaft. Wait for the accident to happen. The current support plan for the gear shaft during repair is to support the gear shaft at the end of the gear shaft to keep the gear shaft in a relatively stable state. At the same time, stop...

AI Technical Summary

Problems solved by technology

[0004] 1. The support is a sleeper, which usually requires several sleepers to be stacked for use. The stacking of sleepers has poor stability and a low safety factor. There are potential safety hazards in the repair process, which does not conform to the production concept of safety first;

[0005] 2. The maintenance platform needs to prepare sleepers of various sizes as spares at the same time, occupying the maintenance operation platform which is not spacious at all, and does not meet the 6S management of the site;

[0006] 3. Limited by the thickness of the sleepers, the support height is not flexible enough. For gear shafts of different sizes, sleepers of different sizes need to be adapted for support, and the work efficiency is low;

[0007] 4. Use sleepers as support. When performing flame cutting operations, the sleepers will burn due to high-temperature flames, producing thick smoke, which will affect the normal operation;

[0008] 5. When the support point needs to be replaced during the repair of the gear shaft, it is necessary to re-adapt the sleeper for support, and the work efficiency is low;

[0009] 6. The pad stop blocks in the landing gear are relatively random. Usually, two small sleepers are randomly placed on both sides of the landing gear. The stability cannot be guaranteed and the reliability is low;
