High-speed and heavy-load track fixing system

Abstract

The invention discloses a high-speed and heavy-load track fixing system. The system comprises a base, a track bottom rubber cushion plate, a bottom plate, a cushion plate, an upper pressing plate, T-shaped bolts, an anchoring system, an adjustment cushion plate and other parts. The horizontal elevation can be adjusted through the thickness of the portion, between the bottom plate and the base, of the cushion plate when the whole system is installed. The high-speed and heavy-load track fixing system has the advantages that the pressing plate can be adjusted in the transverse direction and the longitudinal direction of a track, the adjustable range of the track surface elevation is wide, the high-speed and heavy-load track fixing system is suitable for track adjustment in regions with foundation settlement, the upper pressing plate can be replaced and adjusted and the track surface elevation can be adjusted under the condition that the foundation is not modified, installation and maintenance are convenient and rapid, a three-dimensional vibration reduction and noise reduction system is formed by vulcanized rubber of the upper pressing plate and the track bottom rubber cushion plate, elastic compression can be provided in the vertical direction and the horizontal direction, the steel track vibration can be absorbed and reduced in the vertical direction and the horizontal direction, the position of the steel track is limited through the upper pressing plate and the steel track is prevented from excessive deformation when the amplitude exceeds the system set value, and the running safety of devices is ensured while vibration reduction and noise reduction are conducted by the system for track running devices.

Description

technical field [0001] The invention relates to a rail fixing system, in particular to a rail fixing system for automatic port stackers or other heavy-duty high-speed movements. 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 vibration will be particularly obvious. ...

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
