Abstract

The invention relates to a seamless track stress dispersion rail collision device which comprises a hydraulic pump device, an impact device and a rail collision device, wherein the hydraulic pump device is communicated with the impact device through an oil inlet and an oil outlet; one end of the impact device is fixed on an iron rail, the other end of the impact device is provided with a punch, and the punch movably collides the rail collision device. The whole rail collision process is performed automatically and circularly, so that the low-power hydraulic pump device can reach high power impact effect by means of the impact device, and an engine can not be shut down to complete stress dispersion work until the local displacement of the steel rail reaches the stated requirement of stress dispersion. The invention can be used for rapidly and efficiently completing the stress dispersion work of the seamless track, greatly reducing the labor intensity of workers, and reducing the number of working personnel. The device is a novel machine tool applicable to the seamless track stress dispersion work.

Description

technical field [0001] The invention relates to a stress relief device used on rails, in particular to a stress relief and rail collision device for seamless lines. Background technique [0002] my country began to lay seamless lines in the 1960s, and has mature technologies so far. In order to meet the requirements of high-speed, safe and comfortable transportation, a large number of seamless lines have been laid across the country. The railway works and engineering departments are responsible for the laying and maintenance of the lines, which will inevitably involve the stress relief of the seamless lines. So far, the stress relief operation of the seamless line has been manually pulled by the rail oil hammer for stress relief, which requires a lot of labor, high labor intensity and low work efficiency. [0003] Due to the widespread laying of temperature-stressed seamless lines in my country's railways, the present invention is a special machine for performing stress rel...
