Embodiment Construction

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

[0013] A torsion device for steel rails includes: 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 turntable 4 is located on the support Between the frame 2 and the clamping mechanism 2, the support frame 2 is provided with a channel 3 for passing through and supporting the steel rail, the top of the base 1 is provided with a groove 5, and the turntable 4 has a groove extending along its diameter. 5 and suspended installation, the turntable 4 is provided with through holes distributed along its axial direction. The through hole section is a quadrilateral whose two ends are arc-shaped and the other two sides are parallel. A mold for installing the guide rail is clamped in the through hole. 5. The shape of the mold 5 matches the shape of the through hole. A pair of symmetrical ear plat...

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 steel rail processing device, in particular to a torsion and bending device for steel rails. Background technique [0002] The steel rail is the main component of the railway track. Its main function is to guide the wheels of the rolling stock to move forward, bear the huge pressure of the wheels, and transmit it to the sleepers. The rail must provide a continuous, smooth, and low-resistance rolling surface for the wheels. Therefore, the plane of the rail must be reshaped. At the same time, the use of the rail in the bend also requires pressure on the rail to make the rail bend. In the prior art, many equipment It is a single function. Therefore, when there are multiple problems with the rail, the processing of so many processes requires multiple equipment to cooperate, and the benchmarks need to be constantly replaced. Constantly fixing this can easily cause errors. The rail processing errors can easily cause the rail during use....
