Abstract

The invention discloses a subway overhead line system overhaul barrow which comprises a rail flat car. The rail flat car is provided with a generator set, an electric control operation table and a hydraulic power unit. The top of the rail flat car is provided with a paying-off device and a lifting rotation operation platform. The lifting rotation operation platform is provided with an operation tool. The barrow has the advantages that the paying-off device and the lifting rotation operation platform are arranged, so that paying-off, installation, adjustment, overhaul, daily examination, maintenance and the like of equipment on the upper portion of an overhead line system can be achieved at the same time in a power failure state, use is convenient, operation is easy, and resources are sufficiently utilized.

Description

technical field [0001] The invention relates to a wire-releasing vehicle for maintenance and maintenance of a subway catenary. Background technique [0002] With the acceleration of urbanization in our country, urban traffic congestion has become a bottleneck restricting urban development. In order to solve this situation, local governments vigorously develop urban rail transit, and subway is a very important part of urban rail transit. The catenary provides power for the subway rail vehicles, and the maintenance of the catenary needs to replace the catenary and maintain other catenary equipment. The existing catenary pay-off vehicle is only equipped with a pay-off device for installing the catenary and the load-bearing cable reel. In the actual use process, it needs to be used together with the catenary work vehicle. The catenary work vehicle is equipped with a lifting and rotating work platform. The car-link system realizes replacement of catenary and maintenance of othe...
