Method for hanging wheel set of locomotive vehicle

Abstract

The invention discloses a method for hanging a wheel set of a locomotive vehicle. The failed wheel set is separated from a rail through the vertically upward support force supplied by a jack, is in a hung state over the rail and then tightly tied to a running gear bogie through an auxiliary fastening device, a support device is installed on a normal wheel set adjacent to the failed wheel set, therefore, the running gear bogie is in an inclined state to share the pressure of the whole locomotive vehicle on the running gear bogie, and then the locomotive vehicle can run at low speed in the state that a failed wheel is hung.

Description

technical field [0001] The invention relates to the field of suspension methods, in particular to a method for suspension of a locomotive wheel set. Background technique [0002] The electric locomotive is a heavy-duty high-power AC transmission locomotive. It adopts advanced network control technology and AC motor drive. It has the advantages of simple operation, large traction force, low energy consumption, and high localization degree. It has become the main traction locomotive for trunk freight. . [0003] With the continuous increase of locomotive travel kilometers, the faults of the running part also gradually appeared, and the fixed failure of the locomotive driving wheel occurred; in order to prevent the expansion of the fixed failure of the locomotive driving wheel, the faulty locomotive would stop running and wait for rescue; to maintain the normal transportation order of the railway network, so as to ensure the safety of railway transportation and economic benefi...

AI Technical Summary

Problems solved by technology

[0004] However, the running part of the locomotive ensures that the traction force of the locomotive can be evenly distributed on the six wheelsets under high-load conditions through the three-axle bogie and the high-round spring side bearing structure. The motor bearings and axle box bearings are burned. The fixed failure of the wheelset will be caused after the failure of the moving gear, such as stuck, broken teeth, etc., which will seriously affect the normal running order of the railway; but the locomotive's front part is too heavy, and the general rescue equipment cannot lift the locomotive. The rescue method of separating the driven gear has high requirements on the site environment and machinery and equipment for rescue, and it is impossible to quickly repair the running part of the locomotive to achieve the purpose of quick rescue, resulting in a lot of waiting time after the running part of the locomotive is damaged. Special equipment is used for maintenance, and the rescue environment also has high requirements. In some places, even rescue equipment cannot enter
