Simple elevator door opening mechanism

Abstract

The invention discloses a simple elevator door opening mechanism which comprises an upper threshold, a quick door guide track, a slow door guide track, a quick door sliding plate, a slow door sliding plate and a linkage steel wire rope. The quick door guide and the slow door guiding track are fixed on the upper threshold transversely. The quick door sliding plate can be installed on the quick door guiding track in sliding mode through an upper hanging wheel I and a lower roller I arranged on the quick door sliding plate. The slow door sliding plate can be installed on the slow door guiding track in sliding mode through an upper hanging wheel II and a lower roller II arranged on the slow door sliding plate. Two circular wheel grooves are arranged on a rolling face of the upper hanging wheel II parallelly, one wheel groove butts against the slow door guiding track, and the other wheel groove is connected with the linkage steel wire rope. The simple elevator door opening mechanism has the advantages of being simple in structure and low in construction cost.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a simple elevator door opening mechanism. Background technique [0002] At present, some car elevators adopt the design of fast and slow doors, which have both shutters with faster opening and closing speeds and slow doors with slower opening and closing speeds. The elevator door opening mechanism with double door guide rails (shutter guide rails and slow door guide rails) (can It is an elevator door opener, or an elevator landing door device) is an important part of this type of car elevator, which includes an upper sill, a shutter guide rail and a slow door guide rail arranged laterally outside the upper sill, and a shutter slide installed on the shutter guide rail. , and the slow door slide plate installed on the slow door guide rail, wherein the shutter slide plate and the slow door slide plate are respectively slidably installed on the shutter guide rail and the slow door guide rail...

AI Technical Summary

Problems solved by technology

[0003] Yet the slow door slide plate on the existing this double guide rail elevator door-opening mechanism, the upper hanger wheel and the wire rope pulley on it all are designed separately, that is: both the upper hanger wheel and the wire rope pulley are arranged on the slow door slide plate. The upper hanging wheel is arranged on the guide rail of the slow door for rolling on the guide rail, and the wire rope wheel is used to connect the linkage wire rope to realize the linkage between the shutter slide plate and the slow door slide plate. This structure is very complicated and wastes cost
