Guide rail module with vibration damping function

Abstract

The invention relates to the technical field of vibration reduction of elevator guide rails, in particular to a guide rail module with the vibration damping function. The guide rail module with the vibration damping function comprises a T-shaped guide rail, wherein a vibration absorption damping bar in the length direction of the guide rail is installed on the back side of the guide rail, a notch is formed in the middle of the vibration absorption damping bar, a power vibration absorption mechanism which is arranged according to the first-order natural frequency of the guide rail is further installed on the back side of the guide rail, the power vibration absorption mechanism mainly comprises an L-shaped support, a vibration absorption spring and a vibration absorption mass block, the L-shaped support is embedded in the notch and fixed to the back side of the guide rail, the vibration absorption mass block is placed on the transverse beam of the L-shaped support, one end of the vibration absorption spring is connected with the vertical beam of the L-shaped support, and the other end of the vibration absorption spring is connected with the vibration absorption mass block. With the guide rail module with the vibration damping function, the maximum amplitude can be reduced, and also, the effect of reducing vibration is achieved.

Description

technical field [0001] The invention relates to the technical field of vibration reduction of elevator guide rails, in particular to a guide rail module with a vibration reduction function. Background technique [0002] Elevator guide rails are elevator components composed of steel rails and connecting plates, which are divided into car guide rails and counterweight guide rails. While the guide rail plays a guiding role, it also bears the impact of the car and the elevator when braking. [0003] Usually, the distance between adjacent guide rail supports is 2.5m. When the guide shoes move relative to each other on the guide rail, vibration will be generated, and the maximum amplitude is at the middle position of the adjacent supports. However, the damping coefficient of most existing elevator guide rails is low, and the vibration is obvious and the amplitude is relatively large. Contents of the invention [0004] The technical problem to be solved by the present invention...
