Abstract

The invention relates to the field of railway construction equipment, and discloses a hydraulic rail bender for railway track construction, which comprises a rail bender main body, the side surface of the rail bender main body is fixedly sleeved with a limiting middle shaft, and one end of the rail bender main body is provided with a first hydraulic cylinder close to one side of the limiting middle shaft; a top plate is fixedly connected to a piston rod of the first hydraulic cylinder, an arc groove located in the other side of the limiting middle shaft is formed in the rail bender body, and the rail bender body is movably sleeved with a middle rotating shaft located in the circle center of the arc groove. By means of the structural design of the rotating triangular plate on the rail bender body, one corner of the triangular plate rotates to apply pressure to bend a rail, and the other two corners of the triangular plate are limited in cooperation with the arc grooves, so that in the rail bending process, energy consumption of hydraulic drive rail bending is effectively prevented from being increased, and friction loss of a piston rod of a hydraulic cylinder is likely to be large; therefore, the service life of the hydraulic rail bender is prolonged.

Description

technical field [0001] The invention relates to the field of railway construction equipment, in particular to a hydraulic rail bender used for railway track construction. Background technique [0002] The hydraulic bender is a kind of railway construction equipment used for rail bending. It is a common tool for bending rails during installation and maintenance. Through hydraulic pressure, one end of the piston rod presses the rails to make the rails bend. To the required angle, reduce the labor intensity of workers, improve work efficiency, and improve the quality of track construction and maintenance. [0003] However, the existing hydraulic rail bender directly pushes the rail to bend from one side of the rail, and the reaction force after the rail is bent makes the piston rod of the hydraulic cylinder not only receive a reaction force toward the direction of the cylinder body, but also a force perpendicular to the direction of the cylinder body. As a result, the friction...
