Corridor elevator

Abstract

The invention discloses a corridor elevator. The corridor elevator comprises a track group arranged along a moving direction of stair handrails, a cross shaft chain penetrating through the track group, a driving mechanism for dragging the cross shaft chain to operate along a track and a hoisting rod seat hoisted on the tail end of the cross shaft chain; the track group comprises a main track located in the middle, two auxiliary tracks located at one side of the main track and two straight tooth racks located at the other side of the main track; and the cross shaft chain penetrates through the main track. By adopting the split structure of a direct current motor and the hoisting rod seat, the structure of the hoisting rod seat is simplified, the hoisting rod seat is hoisted in the track group and can be automatically folded and rotated, such that the corridor space is greatly saved; the track and the racks adopt a standard part assembly manner, such that the corridor elevator is suitable for a staircase of various structures and is easy and feasible to measure and mount, a dual insurance safety device is adopted, accidents in operation are avoided, and a safety coefficient is improved.

Description

technical field [0001] The invention relates to the technical field of existing building reconstruction, in particular to a stairway elevator installed in the stairwell of the existing building. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. [0003] The national standard "Code for Residential Design" that came into effect on June 1, 1999 stipulates that "elevators must be installed for residences with seven floors or above or the height of the top floor of the residence from the outdoor design ground exceeds 16m." After the promulgation of this standard Residential buildings or other public buildings must be equipped with ...

AI Technical Summary

Problems solved by technology

The structure of the stair lift is generally composed of three parts: the track, the driving device, and the seat. There are two types of structures: continuous and segmented. Although this type of elevator can transport people or However, the segmented structure is inconvenient to use, and the continuous structure takes up a lot of space and has poor safety. It has not fundamentally solved the problem of travel difficulties for elderly residents above the fifth floor.
