Problems solved by technology

The process of padding rollers at both ends of the welded joint of the rail is complicated, the workload is heavy, and the construction efficiency is extremely low
In addition, when welding rail repairs in subway tunnels, the available welding space in the tunnels is quite narrow, and the overall dimensions of general welding machines basically do not meet the requirements for use.
It is more inconvenient to use the traditional way of raising the rails at both ends of the welded joint with rollers, and even the rail welding operation cannot be performed

Abstract

The invention discloses a rail lifting device for a movable steel rail flash welding machine, which comprises a fixture, lifting oil cylinders, a mounting bracket, guide rails and a lifting part, wherein the lifting oil cylinders are arranged on the mounting bracket; the fixture is assembled and connected with piston rods of the lifting oil cylinders by a lifting part; the guide rails are arranged on the mounting bracket; and the lifting part is in sliding fit with the guide rails. The rail lifting device is convenient to carry out rail lifting; labor intensity of a constructor is greatly reduced; construction efficiency is high; and the rail lifting device also has the characteristics of simple structure, light weight, flexibility for operation, high rail lifting load, capability of being used for lifting up an unlimited long rail string, convenience for assembling and disassembling and the like.

Description

technical field [0001] The invention relates to flash butt welding equipment, in particular to a rail lifting device of a mobile rail flash welding machine. Background technique [0002] At present, when using a mobile rail flash welding machine for online or offline welding, the rails at both ends of the welded joint must be raised with rollers so that the welder can clamp and weld the rails to be welded. The process of padding rollers at both ends of the welded joint of the rail is complicated, the workload is large, and the construction efficiency is extremely low. In addition, when welding rail repairs in subway tunnels, the available welding space in the tunnels is quite narrow, and the overall dimensions of general welding machines basically do not meet the requirements for use. It is more inconvenient to use the traditional way of raising the rails at both ends of the welded joint with rollers, and even the rail welding operation cannot be performed. Contents of th...
