Corridor elevator control method

Abstract

The invention discloses a corridor elevator control method. When an elevator meets a barrier during descending, vertical reciprocating motion is performed, whether the barrier below the elevator exists or not is probed by triggering a limiting switch, a track frame can automatically descend to the bottom position on the condition that the barrier disappears, and the track frame is stopped on the condition that the barrier exists for a long time; the barrier is removed through personnel intervention, and the phenomena that the personnel are injured and equipment is damaged due to forcible descending are avoided; when the elevator meets a barrier during ascending, emergency braking is performed, the control right of a traction control button is cut off, a rider is prevented from conducting the ascending operation forcibly, and the phenomena that the personnel are injured and the equipment is damaged due to forcible ascending are avoided.

Description

technical field [0001] The invention relates to a control method of special equipment, in particular to a control method of a corridor elevator. Background technique [0002] In the multi-storey residences (5-9 floors) built in my country in the 1980s and 1990s, the vertical traffic problem of multi-storey residences has become the most critical problem for the elderly population in cities due to the absence of elevators. People often sit on the building supervisor. Governments at all levels are also trying to find a way to solve this problem, especially Guangzhou, Shanghai, Beijing and other places are piloting the scheme of installing box elevators in old multi-storey houses, but during the pilot process, it is found that the old multi-storey Adding box-body elevators to residential buildings has complex approval procedures, unapproved land area occupied by the shaft, high renovation costs, long construction period, and differences in opinions arising from unequal benefits...

AI Technical Summary

Problems solved by technology

[0005] 1) The control method of the corridor elevator is relatively simple. When encountering a fault, there is a lack of necessary coping strategies. For example, when the rail car is ascending or descending, when an obstacle is encountered, the existing corridor elevator cannot make reasonable emergency actions. It is easy to cause personal injury and equipment damage;

[0006] 2) The walking mode of the traction steel wire of the traction mechanism is unreasonable, which leads to the deviation and detachment of the traction steel wire, and the equipment failure is prone to occur;

[0007] 3) The upper sensing mechanism and the lower sensing mechanism on the pedal are usually connected to the control system with a wire harness, and the frequent retraction and release of the pedal is likely to cause damage to the wire harness, thus destroying the emergency protection performance;

[0008] 4) There is no corresponding detachment prevention structure for the steel wire rope used to realize pedal rotation and rail car drive, and the steel wire rope is easy to detach from the corresponding driving wheel or roller, which is easy to cause interference to moving parts and cause safety accidents;

[0009] 5) The setting of the compression spring of the safety emergency stop device is unreasonable. Most of the two compression springs are installed in an inner and an outer casing. Due to the limitation of the installation method, it is difficult to choose a matching model for the compression spring
