Description

Corridor elevator

Technical Field

The invention belongs to the technical field of elevator equipment, and particularly relates to a corridor elevator.

Background

At present, most of old residential district commercial houses built more than twenty years ago are basically not provided with elevators and are generally only 5-6 floors high. For persons with mobility disabilities, the persons need to climb up and down the 5-and 6-storey stairs every day, and the persons are very labourious. If the old community needs to be additionally provided with elevators, a large number of problems such as cost, space, safety and the like need to be overcome, and obviously, the existing community is not practical. Because no elevator is installed, the vertical traffic problem of the multi-storey residential building becomes the most critical problem which puzzles the population of the old people in the city, and a considerable proportion of the old people often sit on the building guardian. People try and find ways for solving the problems, but in the process of trial run, the old multi-storey residential building additionally provided with the box elevator has the series problems of complicated examination and approval procedures, incapability of repeatedly examining and approving the land area occupied by the shaft, high reconstruction cost, long construction period, uneven benefit of low-rise residents, different opinions, influence on lighting and ventilation of low-rise residents, even conflict with the existing building specifications to a certain extent and the like, so that the trial run scheme is continuously stranded.

The existing corridor elevator has three main types, the first type is specially designed for the disabled sitting on the wheelchair, and the corridor elevator can be only used in buildings with large enough corridor space. The second type is a chair type corridor elevator, but only one person can sit at one time, and the practicability of the corridor elevator is not high. The third is relay type corridor elevator, which can be served by sections, and passengers can not wait too long, but only one person can stand at a time because of small footplate. These corridor elevators all use two tracks, all have received the restriction that the corridor space is little, installation elevator turns difficultly.

The existing reasonable solution is to arrange a plurality of elevators close to the wall or the guardrail of the corridor in the corridor, and solve the problem that the old people are difficult to go upstairs and downstairs under the condition of not influencing the normal use of the corridor. Through intensive research, the prior technical scheme has the following problems: 1) the walking mode of the traction steel wire of the traction mechanism is unreasonable, so that the traction steel wire is easy to deviate and separate, and equipment faults are easy to occur; 2) an upper sensing mechanism and a lower sensing mechanism on the pedal are usually connected to a control system by adopting wire harnesses, and the wire harnesses are easily damaged when the pedal is frequently folded and unfolded, so that the emergency protection performance is damaged; 3) for the steel wire rope used for realizing pedal rotation and railcar driving, a corresponding anti-falling structure is not arranged, the steel wire rope is easy to separate from a corresponding driving wheel or a corresponding roller, and interference to moving parts is easy to cause safety accidents; 4) the compression spring of safe scram device sets up unreasonablely, and two compression springs are mostly the installation of the formula of establishing of an interior overcoat, receive the restriction of mounting means, and compression spring hardly selects the model that matches.

Because the old residential building is not equipped with the vertical elevator, cause inconvenience to the resident daily life, and do not have the structural condition of installing the vertical elevator, to this problem various corridor type elevators appear in recent years, like the corridor elevator that patent number CN2015102487929 announces, pull through wire rope pulley mechanism and drive the track frame and realize reciprocating along the corridor, realize steady personnel and transport the function, but also have some defects, adopt the transmission of rope pulley mechanism, rope and long-time operation looks mutual friction of pulley and long-time bending of rope very easily form wearing and tearing even have the possibility of bearing the weight and breaking, cause later stage maintenance expense higher and have the potential safety hazard.
