Box step for overhauling overhead line system of electrified railway

Abstract

The invention relates to a box step for overhauling an overhead line system of an electrified railway. and overcomes the defects that an overhead line system overhauling box step cannot satisfy the actual use requirements compared with the prior art. According to the box step disclosed by the invention, an output shaft of a main motor is mounted on a main decelerator, the main decelerator is fixedly mounted on a short longitudinal beam through a main decelerator supporter, driving wheel components are respectively mounted on the main decelerator and two longitudinal beams, and the number of the driving wheel components is two; the driving wheel components comprise spline shafts mounted on the output shaft of the main decelerator, and the spline shafts are connected with driving shafts through connecting shafts; bearing seats are fixedly mounted on the longitudinal beams, the driving shafts are mounted on the bearing seats, and travelling wheels are fixedly mounted at the ends, outside the chassis of the box step, on the driving shafts. According to the box step disclosed by the invention, the movement of the box step can be electrically controlled, the barycentric regulation of the box step at a bend path can be realized through the adjustment of the length of box step feet, and through the design of a track grasping device, the situation that the box step cannot be overturned in operation is ensured.

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 l...
