Bottom-suspended external shaft elevator system

Abstract

The invention discloses a bottom-suspended external shaft elevator system, and belongs to the technical field of elevators. In order to solve the technical problem of installing an elevator in an oldbuilding, the operating airspace of a lift car in the technology is from the top floor of the first floor or the adjacent platform surface to any upper floor. Under normal conditions, the lift car does not enter the airspace belonging to the first floor, and only when special needs are met can the lift car descend to the ground of the first floor through special control so as to solve the problemthat the external elevator installed in the old building occupies the first floor travel space. The bottom-suspended external shaft elevator system comprises an elevator shaft, the lift car, a lift car guide rail, an machine room control system, a counterweight, a counterweight guide rail, a buffer mechanism and a lower part guide and limit device, wherein the elevator shaft is bottom suspended; under special circumstances, the lift car can descend to the ground of the first floor assisted by the lower part guide and limit device; by means of side buffers, impact beams are installed on both sides of the top of a lift car frame to replace buffer pits at the bottom of the lift car; and the shaft elevator system outside the building can be applied to various building configurations.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to a bottom-suspended external shaft elevator system. Background technique [0002] Elevators have become an indispensable equipment for high-rise buildings, and are gradually becoming a means of transportation for low-rise buildings. Due to historical reasons, a considerable number of multi-storey residences have not installed elevators, and the actual demand for installing elevators in old buildings has become increasingly prominent. Due to the complicated laying of facilities such as sewage, municipal, gas pipelines and optical fiber cables when the old buildings were completed, the cost of pipeline relocation was high, and the coordination between departments was difficult, which brought many problems and risks to the installation of elevators. At present, most of the old buildings directly add elevators outside the building, which leads to problems such as occupying a small ...

Problems solved by technology

[0003] In view of the above-mentioned technical problems, the purpose of the present invention is to solve the problem that it is difficult to install elevators in some old buildings, and propose a bottom-suspended external shaft elevator system, so that the operating space of the car is half a floor or above any platform surface , to any floor above the first floor, which solves the problem of the old building adding an external elevator to occupy the travel space on the first floor
