Abstract

The invention discloses a rail dragging and lifting method for rail laying. An arm lifting device is arranged at the rear end of a tractor body, an inverted U-shaped rail clamping device is arranged on the arm lifting device, and a detachable rolling shaft is arranged at the bottom of the inverted U-shaped rail clamping device; when a rail is dragged, one end of the steel rail is clamped into an inverted U-shaped rail clamping device, then a rolling shaft is connected to the bottom of the inverted U-shaped rail clamping device, a wedge block is plugged between the inner top of the inverted U-shaped rail clamping device and the top of the steel rail, the wedge block, the inverted U-shaped rail clamping device and the rolling shaft are used for fixing one end of the steel rail, and then a traction vehicle body is controlled to move to drag the steel rail; and when the rail is lifted, one end of the steel rail is clamped into the inverted-U-shaped rail clamping device, the rolling shaft is connected to the bottom of the inverted-U-shaped rail clamping device, then the lifting arm device is controlled to ascend, one end of the steel rail is lifted, the traction vehicle body is controlled to move, and the rolling shaft rolls along the bottom of the steel rail, so the steel rail is gradually lifted from one end to the other end. The labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to a method for dragging and lifting a rail, in particular to a method for dragging and lifting a rail when laying rails, and belongs to the technical field of rail laying operations. Background technique [0002] From the construction of the first domestic railway to the present, my country's railway construction has a history of more than 150 years. Especially in recent years, domestic railway technology has advanced by leaps and bounds, and high-speed railways have also been successfully opened and operated. According to different track forms and working conditions, the laying types of railway tracks are diverse. [0003] Track laying operation refers to the construction process of laying rails, sleepers, turnouts and other rail materials on the specified position of the line in a certain way after the roadbed is repaired according to the construction technical standards. There are two ways of laying rails: manual and mechani...
