Problems solved by technology

[0002] The current elevator is to design the sliding track strip of the opening and closing door on the elevator cabin to go up or down together with the elevator cabin. This design often leads to the occurrence of shearing accidents, and the elevator starts to go down when the elevator door is not closed or is not completely closed. or boost

Embodiment 1

[0020] Embodiment 1: An elevator for avoiding shearing accidents, comprising a car body, a car body lifting passage, floor opening and closing doors 4, lifting steel ropes, and a buffer device, wherein the car body includes a car body sliding opening and closing door 8. Sliding track strips and door knives for opening and closing doors; the door knives run up and down with the car body, and the door knives are designed to bend around the track B 2 and track A 6 on the inner wall 12 of the car body lifting passage; the opening and closing The door sliding track strip is divided into two parts: the door top track strip 1 and the door bottom track strip. A part of the track A 6 of the door sliding track strip is set on the top of the car body, and the other part of the track B 2 is set on the opening of each floor. On the inner wall 12 of the car body lifting passage parallel to the door-closing running track 3, when the car body runs to overlap with the floor opening and closing ...

Embodiment 2

[0021] Embodiment 2: As described in Embodiment 1, if the car body sliding opening and closing door 8 is a double door, the track A 6 and track B 2 are installed on the left and right; if the car body sliding opening and closing door 8 is a single opening, Track A 6 and track B 2 are installed in parallel on the same side.

[0022] Working principle: When the elevator car runs to overlap with the opening and closing door 4 on the floor, track A 6 and track B 2 meet to form a complete track, and the sliding opening and closing door is pulled by the door knife, and the door top and bottom The top runs from the track running up and down with the car body to the top track A6 end and the bottom track B 2 end fixed in the floor. The door knife is designed to bend around the track B 2 on the inner wall 12 of the lift passage of the car body; slide open and close The door is opened synchronously with the floor opening and closing door 4; the track B 2 is designed as an inner-shaped gr...

Abstract

The invention discloses an elevator preventing the generation of a scissoring accident, and relates to an elevator, in particular to a safety elevator. One part of a rail A of an opening / closing door slide rail strip is arranged at the top end of a car body; the other part of a rail B is arranged on the inner wall of a car body lifting channel parallel to each floor opening / closing door operation rail; when the car body is operated to be overlapped with floor opening / closing doors, the rail A and the rail B are in butt joint to form a complete rail, and a slide opening / closing door and the floor opening / closing doors are synchronously opened; and when a door of the car body is not closed, the edge of the slide opening / closing door of the car body is clamped by the slide rail strip on the inner wall of the car body lifting channel, and the car body is not ascended or descended at this moment, so that the generation of the scissoring accident is effectively prevented.

Description

technical field [0001] The invention relates to an elevator, in particular to a safety elevator. Background technique [0002] The current elevator is to design the sliding track strip of the opening and closing door on the elevator cabin to go up or down together with the elevator cabin. This design often leads to the occurrence of shearing accidents, and the elevator starts to go down when the elevator door is not closed or is not completely closed. or boost. Contents of the invention [0003] In view of this, the present invention provides an elevator for avoiding shearing accidents. The sliding track for opening and closing doors at the top of the car body is divided into two parts, one part runs up and down with the car body door, and the other part is arranged on each floor to lift the car body up and down. On the inner wall of the passage, when the door of the car body is not closed, the sliding track strips on the inner wall of the lifting passage of the car body ...
