Pull-type corridor elevator frame

Abstract

The invention relates to a pull-type corridor elevator frame, and belongs to the technical field of general equipment, namely elevators. The pull-type corridor elevator frame comprises an upper guidewheel assembly, a lower guide wheel assembly, a machine frame and a trailer frame. The upper guide wheel assembly is composed of a swing mechanism and guide wheels, a swing frame is fixedly connectedwith a swing shaft, the swing shaft is installed in a bearing, a bearing pedestal is fixed to a vertical plate on the machine frame, and the horizontal guide wheel, a guide rail and the vertical guidewheel are arranged on the swing frame. The lower guide wheel assembly is also composed of a swing mechanism and guide wheels, the machine frame comprises a vertical plate and a hexahedral cubic frame, and a power assembly comprises a gear motor and a gear. The gear motor is installed on the vertical plate, and a gear is installed on an output shaft of the gear motor and meshed with a rack below alower guide rail. A trailer is flexibly connected with the machine frame, and bearing wheels are arranged at the bottom of the trailer. The pull-type corridor elevator frame has the main characteristics that the guide and the bearing can be separated or stacked, and the normal passage of a corridor is not influenced basically; and in addition, the elevator load bearing is large, the carrying capability is strong, the rack is located below the guide rail, sundries are not prone to falling on the rack, and the 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 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 affects the normal pass...

Problems solved by technology

However, this kind of elevator also has an obvious disadvantage, that is, the curved guide rail takes up a lot of space, which affects the normal passage of the corridor.

Due to the above reasons, existing corridor elevators are mostly used in buildings or private residences below three floors, and are difficult to popularize in multi-storey residences that urgently need to solve the difficulty of climbing stairs.
