Comprehensive operation vehicle of railway contact system

Abstract

The invention provides a comprehensive operation vehicle of a railway contact system. The comprehensive operation vehicle of the railway contact system comprises an operation system, a vehicle body and a power transmission system, wherein the power transmission system comprises a power transmission device and an operation power system, the power transmission device comprises an engine and a hydraulic transmission case, and the output end of the hydraulic transmission case is connected with one end of a bogie to drive a wheel set to travel at high speed; and the operation power system comprises an operation engine, a transfer case, a travel pump, an operation pump and a pump for a locking system, the three output ends of the transfer case are respectively connected with the input ends of the travel pump, the operation pump and the pump for the locking system, the operation pump drives a lifting wire shifting device, an operating platform and an overhead working bucket to operate, the output end of the travel pump is connected with the input end of a low-speed travel motor, the output end of the low-speed travel motor is connected with the other end of the bogie to drive the wheel set to travel at constant low speed, and the pump for the locking system drives the bogie to lock the operation of an oil cylinder. The comprehensive operation vehicle is supplied with power through two engines, the hydraulic transfer case is utilized to respectively drive the bogie to travel at high speed, and the operation engine is used to supply power for the low-speed traveling and locking of the oily cylinder and the operation system.

Description

technical field [0001] The invention belongs to the technical field of railway track maintenance machinery, and in particular relates to a comprehensive operation vehicle for railway catenary. Background technique [0002] With the large-scale speed increase of existing railway lines in my country to 160-200km / h and the opening of new passenger dedicated lines of 200km / h and above, the maintenance of catenary has also been raised to a new level. The existing operating vehicles adopt a set of power systems. The driving and operating power adopt a set of power system, which not only has unsafe factors, but also has high energy consumption. It is difficult to adapt to the needs of railways in the new situation. The high-speed, efficient and high-reliability integrated operation vehicles will become the mainstay of railway catenary maintenance. The new needs of the department, so it is necessary to improve.

[0002] With the large-scale speed increase of existing railway lines in my country to 160-200km / h and the opening of new passenger lines of 200km / h and above, the maintenance of catenary has also been raised to a new level. The existing operating vehicles adopt a set of power systems. The driving and operating power adopt a set of power system, which not only has unsafe factors, but also has high energy consumption. It is difficult to adapt to the needs of the railway under the new situation. The high-speed, high-efficiency and high-reliability integrated operation vehicle will become the mainstay of railway catenary maintenance. The new needs of the department, so it is necessary to improve
