A kind of I-beam steel rail calibration and alignment device for railway construction

Abstract

The invention discloses an I-shaped steel rail calibration and alignment device for railway construction, which comprises a mounting frame, a first bevel gear, a second bevel gear and a first adjustment rod. A mounting ring is arranged above the mounting frame, and the The inner side of the ring is provided with a vertical bar, the surface of the vertical bar and the inner surface of the mounting ring are provided with grooves, and the inner side of the groove is provided with balls, and the vertical bar is connected to the mounting ring through the balls. Grip spikes are installed below. The I-shaped steel rail calibration and alignment device for railway construction, while the first clamping plate under the first mounting plate clamps the rail, the first clamping plate will drive the second clamping plate to clamp the other rail synchronously through the telescopic rod Hold, and the first clamping plate and the second clamping plate are located in the same linear position, so the rail clamped by the first clamping plate and the rail clamped by the second clamping plate are in the same linear position, at this time, the two sections of rails are carried out alignment for subsequent butt welding.

Description

technical field [0001] The invention relates to the technical field of railway construction, in particular to an I-shaped steel rail calibration and alignment device for railway construction. Background technique [0002] In recent years, with the rapid development of China's economy, the transportation between cities has become more and more convenient, especially the opening of high-speed rail. As the basic hardware of high-speed rail tracks, the importance of rails in railway construction cannot be overstated. For example, in order to facilitate the transportation of rails, longer rails are usually spliced ​​and welded by multiple short rails transported in place. In order to improve the welding quality and prevent unwanted displacement of the rails during the welding process, it is best to The track to be welded is limited or fixed, but most of the existing rails have the following problems in the butt installation process: [0003] 1. It is inconvenient to fine-tune th...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an I-shaped steel rail calibration and alignment device for railway construction, to solve the inconvenience of fine-tuning the position of the rails proposed in the above-mentioned background technology. Cooperating between two workers seriously wastes the labor force. At the same time, the work efficiency of this fine-tuning and calibration method is poor, which seriously affects the construction progress of the rails. After calibration and alignment, it is still inconvenient to carry out displacement docking, and the problem of position deviation may occur during displacement docking
