Guide rail vibration isolation structure

Abstract

A guide rail vibration isolation structure comprises elevator guide rail fixed plates, a support steel structure, elastic vibration reduction pieces and adjusting bolts, wherein an elevator guide rail is mounted on the support steel structure through the guide rail fixed plates rather than directly fixed and mounted on a steel sectional material; the elastic vibration reduction pieces are connected with the support steel structure through the adjusting bolts and are fixed on a building structure in a lift shaft through mounting screw holes on the two sides; rigid connection between the elevator guide rail and the building structure is eliminated, as a result, solid transmission of structure vibration of the elevator guide rail is cut off; each support steel structure is provided with two elastic vibration reduction pieces, and bolt holes for the adjusting bolts are uniformly formed in the planes of the front side, left side and right side of each elastic vibration reduction piece, the perpendicularity of the elevator guide rail and parallelism between two elevator guide rails can be conveniently adjusted, and friction and vibration noise is reduced.

Description

technical field [0001] The invention relates to a vibration and noise control transformation, which prevents low-frequency vibration and noise solid transmission caused by sliding friction of guide rails during elevator operation. Background technique [0002] The elevator car and the elevator counterweight frame slide in the way that U-shaped guide shoes are fixed to the elevator guide rails on both sides. The elevator guide rails are fixed on the inside of the elevator shaft. Install directly with the building structure in the hoistway. When the elevator is running, the friction between the guide shoe (guide wheel) and the elevator guide rail when the car, the counterweight frame and the main rail run up and down, the friction and vibration between the rotating parts and the traction rope, the vibration of the traction machine system through the traction The transmission of the rope to the car will also be transmitted to the guide rail. The vibration enters the building s...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the low-frequency vibration noise solid transmission caused by the sliding friction of the elevator guide rail and the shortcomings of changing the U-shaped guide shoe into a rolling pulley block, the purpose of the present invention is to provide a vibration-isolation installation structure for the elevator guide rail, which can block the vibration transmission path of the structure and can Effectively control the vibration transmission of elevator guide rails, and eliminate the impact of low-frequency vibration and noise on residents
