Flexible gear driven corridor elevator walking mechanism

Abstract

The invention relates to a flexible gear driven corridor elevator walking mechanism, and belongs to the technical field of general equipment of elevators. The flexible gear driven corridor elevator walking mechanism comprises a load bearing wheel assembly, a machine frame, a power assembly and a supporting wheel assembly, wherein the load bearing wheel assembly comprises a wheel frame, a load bearing wheel and guide wheels; the cross section of the wheel frame is like a door frame; the load bearing wheel is positioned in the middle of the wheel frame and is horizontally arranged; the guide wheels are positioned at two wings of the load bearing wheel and are vertically arranged; the load bearing wheel and the guide wheels form a structure like a Chinese character 'pin'; and a load bearing guide rail is encircled in the center. The machine frame is an elevator body framework and is mechanically connected with the load bearing wheel assembly through a hanging plate. The power assembly comprises a speed reducing motor and a gear; the gear and the speed reducing motor are flexibly connected, and are meshed with a rack on a corridor; and support wheels are positioned below the gear. The flexible gear driven corridor elevator walking mechanism has the main characteristics that the width of each of the guide rails and the rack protruding a guardrail does not exceed 5 cm, and the normal passage of the corridor is not influenced basically. In addition, the rack is positioned between the bearing guide rail and a supporting guide rail, and an unbalance-loading crawling phenomenon can be relieved.

Description

technical field [0001] The invention belongs to the technical field of general equipment-elevators Background technique [0002] In recent years, in order to help the elderly go up and down the stairs, a new type of stair-climbing tool-corridor elevator came into being. Existing corridor elevator can be divided into linear type and curved type two classes according to running trajectory. The advantage of the straight type is that it takes up less space in the corridor, but the disadvantage is that because the track cannot be turned, an elevator can usually only climb half a floor. Like this, just need many relays if use linear elevator for the building more than two floors. The advantage of the curved shape is that the elevator can run continuously and uninterruptedly between floors, so the buildings used are theoretically not limited by floors. But this kind of elevator also has an obvious disadvantage, that is, the curved guide rail takes up a lot of space, which affect...
