A railway track bolt tightening device and method thereof

Abstract

The invention provides a railway track bolt tightening device and a method thereof. The railway track bolt tightening device comprises a frame, wherein a power source, a main control device, a lifting counterpoint device, a walking device, a lighting device and a displacement device are arranged on the frame, the displacement device is connected with a shaft control device, the shaft control device is connected with a tightening shaft, the tightening shaft is connected with a lifting counterpoint device, and the lifting counterpoint device is connected with a torque output mechanism; and the main control device is respectively connected with a power source, the shaft control device, the walking device, the lighting device and the displacement device. The railway track bolt tightening device provided by the utility model has a simple structure and is convenient to operate, can meet the task for demounting various center distance lower bolt nuts such as common tracks, high-speed rail passenger tracks and the like, has strong versatility, can accomplish railway track pavage and maintenance tasks in a way of high efficiency, high precision and high quality, the labor intensity is lowered greatly, can get rid of distance limitation of a wired AC power supply within a certain range, has a wider operation coverage, and has the operation capability in gloomy ray environment such as at night or in a tunnel and the like.

Description

technical field [0001] The invention relates to the field of railway track laying and maintenance equipment, in particular to a railway track bolt tightening device and a method thereof. Background technique [0002] At present, due to the maturity and wide application of high-speed rail and bullet train technology, the speed of domestic passenger and freight trains has been greatly increased, and the traffic density has gradually increased. The frequency and quality requirements of roadbed and track maintenance are more stringent. Therefore, the rapid increase in the speed of railway transportation brings convenience to people’s lives, but also brings new challenges to the safety of railway transportation. Only by doing a good job of roadbed and track maintenance in accordance with the regulations can the safety of high-speed railway transportation be guaranteed. According to the survey, there are more than 150,000 people working in the front line of railway track maintena...

AI Technical Summary

Problems solved by technology

[0003] The invention proposes a railway track bolt tightening device and its method, which solves the problems of manual tightening in the prior art, such as high labor intensity, long working time, low work efficiency, inability to guarantee the quality of bolt tightening, large impact and noise in the internal combustion engine motorized bolt wrench. Yamato bolts have low tightening accuracy, and the traditional electric wrench is powered by 220V power supply, which is strictly limited by the power supply and can only be used in a small range of conditional work areas, and cannot meet the requirements of long-term field work.
