Embodiment Construction

[0012] As shown in the figure, the specific implementation method is as follows:

[0013] A rail bending device, comprising: a base 1, a base 6 for supporting the base 1, a turntable 4 and a support frame 2, the support frame 2 and the turntable 4 are arranged on the base 1 at intervals, and the support frame 2 is provided with There is a channel 3 for piercing and supporting the rail. The top of the base 1 is provided with a groove 5. A section of the turntable 4 extends into the groove 5 along its diameter and is installed in the air. Distributed through holes, the cross-section of the through holes is a quadrilateral whose two ends are arc-shaped and the other two sides are parallel. A mold 9 for installing the guide rail is clamped in the through hole, and the shape of the mold 9 matches the shape of the through hole. A pair of symmetrically arranged ear plates are also extended on the circumferential surface. The ear plates are installed on the base 6 through the hydrauli...

Abstract

The invention discloses a twisting device for a steel rail. The twisting device comprises a substrate, a base for supporting the substrate, a turntable and a supporting frame. The twisting device is driven by hydraulic cylinders and is connected with the hydraulic cylinders through lug plates; when the two hydraulic cylinders synchronously operate, the turntable can be driven to move up and down, so that the bending degree of the steel rail in the vertical direction can be controlled; when one hydraulic cylinder moves actively, and the other hydraulic cylinder moves passively, the turntable can be controlled to rotate to control the bending degree of the steel rail in the horizontal direction, so that the steel rail can be twisted.

Description

technical field [0001] The invention relates to a rail processing device, in particular to a rail twisting device. Background technique [0002] Steel rail is the main component of railway track, its main function is to guide the wheels of rolling stock, bear the huge pressure of the wheels, and transmit it to the sleeper. The rail must provide a continuous, smooth, and low-resistance rolling surface for the wheel, so the plane of the rail must be shaped, and the use of the rail at a bend also requires pressure on the rail to make the rail bend. Many devices in the prior art have It is a single function, so when there are many problems with the rail, the processing of so many processes requires the cooperation of multiple equipment, and the need to constantly replace the reference, and it is easy to cause errors. cause traffic accidents. Contents of the invention [0003] The object of the present invention is to provide a twisting and bending device for rails in order t...
