High-speed vibration reduction and noise reduction environmental protection rail fixing system and its installation method

Abstract

The invention discloses a high-speed vibration-reduction, noise-reduction and environment-friendly track fixing system and a mounting method thereof. The system comprises a steel track, track welding type fastener systems and vibration-reduction type fastener systems; and the track welding type fastener system and the vibration-reduction type fastener system are used for fixing the steel track. The track welding type fastener systems and the vibration-reduction type fastener systems are mounted alternately, good elastic displacement and deformation space and track resilience are provided for the track by the vibration-reduction fastener systems, and vibration reduction and noise reduction of the system of the track are realized; a sufficient restrictive lateral force is provided for the track by the welding type fastener system, the steel track can move and recover in a range in which a track head can be changed, and a fixed track gauge is not changed; and the lateral force generated during running of the high-speed track can be well restrained and released, the problem of rain gnawing caused by high-frequency vibration and lateral displacement due to high-speed running of equipment is solved, automatic stacking machines on a port can run well and stably, and safety and reliability are guaranteed.

Description

technical field [0001] The invention relates to a rail fixing system, in particular to a high-speed vibration-reducing, noise-reducing and environment-friendly rail fixing system and an installation method thereof. Background technique [0002] Port automatic stacker ASC has a span of 28.5 meters, a cart speed of 270 meters per minute, and an acceleration of 0.35 meters per second 2 , 8 wheels on each side, with a wheel load of 32 tons; ASC has a self-weight of about 240 tons; the rail model is MRS87A; the track foundation adopts pile-type concrete continuous beams, and the rails adopt open rail type, basically no settlement. Considering that the load of the equipment itself is relatively large and the operating speed is 270m / min, the high-frequency vibration generated during the operation of the equipment has brought serious tests to the rails, track accessories and track foundation. Especially when the equipment runs at high speed, the lateral force and high-frequency vib...

AI Technical Summary

Problems solved by technology

Especially when the equipment runs at high speed, the lateral force and high-frequency vibration will be particularly obvious. If all the rails are fixed laterally and rigidly, it can only eliminate the vertical displacement caused by the wheel pressure and the self-weight of the equipment when the rails are running. There is no way to release the lateral displacement. After a long period of lateral impact and vibration, the rail gnawing and lateral displacement will seriously damage the rail, rail accessories and track foundation, and shorten the service life of the overall rail
