Abstract

The invention relates to a vehicle ladder used for maintenance of an electrified railway catenary, which solves the defect that the catenary maintenance vehicle ladder cannot meet actual use requirements compared with the prior art. In the present invention, the output shaft of the main motor is installed on the main reducer, and the main reducer is fixedly installed on the short longitudinal beam through the support of the main reducer. The main reducer and the two longitudinal beams are respectively equipped with a driving wheel assembly, and the driving wheel assembly The number is 2, the drive wheel assembly includes a spline shaft installed on the output shaft of the final reducer, the spline shaft is connected with the drive shaft through a connecting shaft, a bearing seat is fixedly installed on the longitudinal beam, and the drive shaft is installed on On the bearing seat, the end of the drive shaft outside the chassis of the ladder car is fixedly equipped with a traveling wheel. The invention can electrically control the running of the ladder, adjust the center of gravity of the ladder at the bend by adjusting the length of the ladder feet, and ensure that the ladder will not overturn during operation through the design of the rail grabbing device.

Description

technical field [0001] The invention relates to the technical field of electrified railway catenary, in particular to a car ladder used for maintenance of electrified railway catenary. Background technique [0002] With the rapid development of high-speed railways in my country, more and more electrified railways are being laid, and the maintenance of the important catenary on the electrified railway is also facing huge challenges, which requires high work efficiency in the daily catenary maintenance process and safety factor. The existing electrified railway catenary maintenance operation car ladder has the following problems in use: 1. 4-6 people are required to push the car ladder to walk when moving, and the labor cost is relatively large; 2. The car ladder structure is mainly integrally connected, and the ladder frame It cannot be disassembled; 3. The ladder frame is made of steel, which is heavy and difficult to carry; 4. The car ladder is prone to overturning from lef...
