Open type abrasive belt rail high-speed grinding vehicle

Abstract

The invention provides an open type abrasive belt rail high-speed grinding vehicle. The open type abrasive belt rail high-speed grinding vehicle comprises working vehicles and power vehicles. A plurality of open type abrasive belt grinding trolleys are hung on each section of working vehicle and each section of power vehicle. Each open type abrasive belt grinding trolley comprises a traction device, a lifting device, a walking device, an abrasive belt winding structure, a driving force replacement structure, a guide structure, a pressing structure and the like. Abrasive belt grinding units are connected with the working vehicles through the traction devices and the lifting devices. An abrasive belt transmission mechanism, a driving force replacement mechanism, a guide mechanism and a pressing mechanism form the whole grinding trolley. According to the open type abrasive belt rail high-speed grinding vehicle, rail grinding is achieved in an open type abrasive belt grinding mode, the train walking speed serves as the abrasive particle cutting speed, high-speed grinding work can be achieved, and the grinding efficiency is improved. The available abrasive belt length in the grinding units can be prolonged through an open type structure. In consideration with elastic grinding and the contact mode of an abrasive belt, rail grinding target profiling can be achieved through mode change of a contact component.

Description

technical field [0001] The invention relates to the technical field of rail grinding, in particular to an open-type abrasive belt rail grinding vehicle at high speed. Background technique [0002] Rails of ordinary railways, high-speed railways, subways and other rail transportation modes will have corrugation, cracks and other diseases on the surface after a certain period of service. It is necessary to regularly use grinding technology to remove the surface defects of the rails to ensure the safety and stability of train operation. . Most of the rail grinding equipment currently on the market has a very low operating speed, generally less than 18km / h, which seriously restricts the improvement of the efficiency of rail grinding operations and cannot make full use of the "skylight time" of railway operations. At present, there is only one kind of passive high-speed grinding equipment for grinding wheels, but it still cannot avoid a series of shortcomings in grinding wheels,...
