Description

Pulling type corridor elevator ladder frame
Technical Field
The invention belongs to the technical field of general equipment-elevator
Background
In recent years, a novel stair climbing tool, namely a corridor elevator, is produced to help the old people go upstairs and downstairs. The existing corridor elevator can be divided into a linear type and a curved type according to the running track. The linear type has the advantages of small occupied corridor space and the defect that one elevator can only climb half floors generally because the track can not turn. Thus, a plurality of relays are needed for the linear elevator of the buildings with more than two floors. The advantage of the curve is that the elevator can run uninterruptedly between floors, so the building used is theoretically not limited by floors. However, the elevator has the obvious defect that the curve guide rail occupies a large space and influences the normal passage of the corridor. For the above reasons, the conventional corridor elevator is mostly used in buildings with three floors or less or private houses, and is difficult to be popularized in multi-storey houses where it is urgently necessary to solve the difficulty of climbing stairs.
