Abstract

The invention discloses a double alloy steel rail distortion correction device which is characterized by being provided with a horizontal C-shaped body, wherein a clamping mechanism and a torsion mechanism are arranged at different axial positions in a C-shaped cavity, and a groove opening of the C-shaped cavity faces upwards; the clamping mechanism pushes clamping sliding blocks arranged at opposite positions by utilizing clamping oil cylinders to clamp the alloy steel rail in an encircling manner; the torsion mechanism pushes torsion clamping sliding blocks arranged at opposite positions by utilizing torsion clamping oil cylinders to clamp the alloy steel rail in an encircling manner, the torsion clamping sliding blocks are arranged in shaft end sliding chutes of a torsion hollow shaft, gear teeth which form a torsion gear are arranged on the periphery of the torsion hollow shaft, a torsion loading oil cylinder drives a rack to stretch and contract, and the rack is meshed with the torsion gear to drive the alloy steel rail to reverse. The double alloy steel rail distortion correction device achieves distortion correction for the alloy steel rail, corrects the distortion repeatedly in a segmental distortion correction mode, and can acquire high distortion correction efficiency and accuracy.

Description

technical field [0001] The invention relates to a torsion correction device for double-layer alloy steel rails. Background technique [0002] The double-layer alloy steel rail is composed of two I-shaped aluminum alloy bodies connected by a steel belt to form a composite double-layer alloy steel rail. During the processing of the double-layer alloy rail, there will be bending deformation and twisting deformation in the blank before processing and the alloy rail after heat treatment. In order to improve the straightness of the alloy rail, it is necessary to correct the torsion of the alloy rail, but so far there is no research on double-layer alloy rail. A public report on special equipment for correcting torsion of alloy steel rails. Contents of the invention [0003] In order to avoid the disadvantages of the above-mentioned prior art, the present invention provides a double-layer alloy steel rail torsion correction device, which provides clamping and torsion loading pow...
