Abstract

The invention provides an approach rail clamp, a rail withdrawal guiding and levering bogie and a long-rail transport bogie unit. The approach rail clamp comprises a first clamp, a second clamp and a hydraulic cylinder, each of the first clamp and the second clamp is provided with a clamping portion used for clamping a steel rail, a driving portion connected with the hydraulic cylinder, and a hinge portion arranged between the clamping portion and the driving portion. The clamping portions of the first clamp and the second clamp are bent inwards to form heaves respectively, and the heaves are clamped in grooves in two sides of the steel rail respectively. The hinge portions of the first clamp and the second clamp are provided with corresponding through holes respectively, bolts penetrate the through holes to be hinged with the first clamp and the second clamp, a piston end of the hydraulic cylinder is connected with the driving portion of the second clamp, and a cylinder end of the hydraulic cylinder away from the piston end is connected with the driving portion of the first clamp. By the aid of the approach rail clamp, the rail withdrawal guiding and levering bogie and the long-rail transport bogie unit, automation can be realized, operation efficiency is improved, and safety risk is reduced.

Description

technical field [0001] The invention relates to mechanical technology, in particular to a guide rail fixture, a rail closing guide, a rail shifting trolley and a long rail transport car set. Background technique [0002] The long rail transport car set is an important equipment for laying seamless railway lines. It has the functions of long rail loading, unloading, and old rail recycling. It is a special vehicle for transportation and construction. [0003] The existing long rail transport car group needs to use a special guide rail clamp to clamp the rail during the rail closing process. The guide rail clamp is designed as a scissors structure, and its opening and closing are all manually operated. The cross-sectional shapes match each other. When clamping the rail, there is a gap in the upper part of the jaw, and a wedge is driven into the gap to clamp the rail. [0004] The disadvantage of the existing technology is that the opening and closing of the guide rail fixture ...
