Unloading device for guide rail of high speed elevator

Abstract

The invention discloses an unloading device for a guide rail of a high speed elevator. The unloading device for the guide rail of the high speed elevator comprises a bearing component which is arranged on the top of a well, and elevator guide rails; the elevator guide rails are suspended under the bearing component; pull rods are arranged on the bearing component; the elevator guide rails are fixed on the pull rods; limiting seats are arranged at the bottom of the elevator guide rails, and gaps remain between the bottom end faces of the elevator guide rails and the limiting seats; the limiting seats are provided with adjusting bolts which are used for adjusting the gaps between the bottom end faces of the elevator guide rails and the limiting seats and the gaps between the limiting seats and a buffer beam. The unloading device for the guide rail of the high speed elevator has the advantages that: the elevator guide rails are under a suspension state, can well keep vertical and straight states and prevent bending and deformation due to pressing when a lower end fixing way is used; adjustable devices are used at the lower ends of the elevator guide rails; the lower ends of the elevator guide rails are suspended at ordinary times and keep the small gaps with the bottom, and contact with the bottom to bear force in special occasions, for example, in the action process of safety tongs of the elevator, so that safety of passengers is ensured.

Description

【Technical Field】 [0001] The invention relates to the technical field of elevators, in particular to a high-speed elevator guide rail unloading device applied to a high-speed elevator running on a guide rail. 【Background technique】 [0002] At present, the guide rails of high-speed elevators generally adopt the lower end fixing method, and the upper guide rails are pushed down, and elastic compression code is adopted. The guide rail will bend and deform after being pressed by gravity. Because the pressing force of the elastic compression code on the guide rail is within a certain range, it does not completely press and fix the guide rail. Therefore, the elevator elastic compression code cannot completely prevent the guide rail from bending and deforming, which causes the elevator to run for a period of time. Increased vibration. [0003] On the other hand, due to the settlement of buildings, about 1mm of each floor of a 10-year-old building will sink. If the building is 30 stori...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to address the above-mentioned deficiencies in the prior art, to provide a solution to the problem of bending and deformation of the guide rail in the lower-end fixing mode in the prior art due to the gravity, and to improve the problem of poor running comfort of high-speed elevators caused by it. At the same time, it can avoid the adverse consequences of guide rail deformation caused by the settlement of the building, and it is a high-speed elevator guide rail unloading device
