Multi-storey elevator

Abstract

A multi-storey elevator further comprises an elevator car which is arranged on one side in a multi-storey building exterior facade recess and is opposite to a staircase. One end of the elevator car is provided with a first automatic induction door which is in linkage with elevator doors at all flat layers on the staircase, and the other end of the elevator car is provided with a second automatic induction door. An overhead beam is arranged above the elevator car, wherein the two ends of the overhead beam are supported by a building body of a multi-storey building, and the overhead beam is transversely arranged at the multi-storey building exterior facade recess. The two sides of the elevator car are each provided with a vertical lead screw, the upper ends of the two lead screws are fixedly connected with the overhead beam, the lower ends of the two lead screws are provided with foot ends fixedly connected with the ground, the two lead screws are each provided with a lead screw lifter, and bodies of the two lead screw lifters are fixedly connected with the elevator car. The elevator car is provided with a bidirectional output shaft motor which is controlled by a control system to operate, and the two lead screw lifters are in power connection with a motor shaft of the bidirectional output shaft motor. The elevator is arranged in the recess space of the exterior facade of the multi-storey building, daylighting of residents is not affected, the embedding fit degree of the elevator and the multi-storey building is high, overall attractiveness is achieved, and the construction and maintenance cost is low.

Description

technical field [0001] The invention relates to a multi-storey elevator, in particular to a multi-storey elevator suitable for rebuilding old houses. Background technique [0002] Our country is gradually entering an aging society. There are no elevators installed in the multi-storey buildings of many old communities, which makes it difficult for the elderly living on the third floor to go up and down. In order to improve the quality of life of the elderly, many communities provide residents with Apply for an external elevator, but most of the residents living in the old community are in poor economic conditions. Among them, the young people who need it are not willing to install it because of the high cost, while the elderly who just need it cannot afford it because of their income constraints. One of the reasons for the slow progress of the elevator renovation project; for now, when adding elevators to multi-story buildings, not only additional land and space at the entran...

[0002] Our country is gradually entering an aging society. There are no elevators installed in the multi-storey buildings of many old communities, which makes it difficult for the elderly living on the third floor to go up and down. In order to improve the quality of life of the elderly, many communities provide residents with Apply for an external elevator, but most of the residents living in the old community are in poor economic conditions. Among them, the young people who need it are not willing to install it because of the high cost, while the elderly who just need it cannot afford it because of their income constraints. One of the reasons for the slow progress of the elevator renovation project; for now, when adding elevators to multi-story buildings, not only additional land and space at the entrance of the multi-story stairwells must be requisitioned to build closed elevator shafts, but also to build elevators. The connection channel between the well and the stairs between each floor is large in size and high in cost, which not only affects the appearance of the community, but also affects the lighting, causing inconvenience to the residents, and the follow-up elevator maintenance, annual inspection and other costs are also high, and the economic burden of the residents It is also heavier; the elevators used in the renovation of old houses did not take into account the structural characteristics of the old houses and the frequency of operation, but applied them on the basis of the structure of high-rise elevators, relying on the steel structure elevator shaft installed later To build the environmental foundation required for the operation of high-rise elevators, and most elevators use the traction machine to pull the car up and down through the wire rope. Because the wire rope may break, it is necessary to arrange safety gear, speed limiter, buffer and other devices. One of the reasons for the high cost of building elevators in old buildings; in existing old multi-storey buildings, most of the facades of multi-storey buildings are designed with a recess opposite to the stairwell. If the space of the recess is used to arrange the elevator, can solve the above problems
