Tramcar starting-free bogie equipment dismounting and replacing tool

Abstract

The invention relates to a tramcar starting-free bogie equipment dismounting and replacing tool. The tool comprises a base and a supporting beam fixed to the upper surface of the base. A supporting pin is arranged at the front end of the supporting bam. A vertical pin falling preventing hole is formed in the head of the supporting pin. Reinforcing rib plates are welded between the front side face of the base and the supporting beam. The base is provided with two cavities allowing lifting arms of a forklift or moving equipment to be inserted into. Fixing threaded holes are formed under the cavities. Bolts are screwed into the fixing threaded holes, and the lifting arms of the forklift or the moving equipment abut against the upper walls of the cavities through the bolts, so that the lifting arms of the forklift or the moving equipment are / is fixed to the base. The requirements for dismounting and replacing bogie equipment in the subsequent maintaining process of a tramcar can be met, the tool is simple and feasible, manpower and material resources are saved, and the bogie using and maintaining efficiency is greatly improved; and the bogie and the tramcar do not need to be disconnected, damage to parts is avoided, and safe and reliable operation of the tramcar can be ensured.

Description

technical field [0001] The invention relates to a bogie equipment tooling for removing and replacing a bogie when the tram is not in operation, and is suitable for fixing cables at axle ends of rail vehicles. Background technique [0002] Due to the unevenness of the track line, rail transit vehicles based on the wheel-rail system will inevitably generate a large amount of vibration during the actual operation process. With the increase of the operating mileage, the state of the wheel-rail changes, such as rail corrugation, wheel out-of-round, The vibration will become more and more severe when the tread is peeled off and scratched. Rail vehicle suspension components are subject to various random vibration tests. The design of elastic suspension devices fully considers the operating environment of the vehicle. In order to reduce the impact of vibration on suspension components and the impact of fatigue life, it is applied to the structural design of rail vehicle suspension c...

Problems solved by technology

At present, most traction motors in China are fixed on the bogie frame by means of frame suspension, and the vibration reduction function is realized through a series of suspension devices between the frame and the wheel set. However, with the continuous development of bogie technology, there is currently a drive The motor is directly mounted on the axle by holding the shaft. In this case, the vibration of the wheel set will be transmitted to the motor structure, which is a great test for the structural reliability and performance stability of the motor. Therefore, in the existing structural scheme Considering the design of the elastic suspension device, the vibration and impact of the motor will be reduced to the greatest extent.
