Double-tractor safety elevator used outside old residential building

Abstract

The invention provides a double-tractor safety elevator used outside an old residential building. The double-tractor safety elevator used outside the old residential building comprises a protective hood, a machine room, guide rails, an elevator car, a first tractor, a base, a second traction mechanism, a buffering mechanism, a control cabinet and an optoelectronic switch sensor. The first tractor,the second tractor, the buffering mechanism and the optoelectronic switch sensor are arranged, and the first tractor and the second tractor are adopted so that when one tractor breaks down, normal operation of the elevator can be ensured, and unsafe situations are avoided when one tractor breaks down; when the elevator car suddenly falls down, a buffering plate makes contact with buffers, and airsprings are matched with the buffers to buffer the impact force of the elevator car, so that the buffering effect of the elevator is improved; and a distance value is set on the optoelectronic switchsensor, and the optoelectronic switch sensor sends an electric signal to a control cabinet to stop the elevator car from operating when the distance between the elevator car and the optoelectronic switch sensor reaches the set value, so that the phenomenon that the elevator car impacts the roof is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to a safety elevator with double traction machines used outside old residential buildings. Background technique [0002] Most of the brick-concrete structure houses built in the 1980s and 1990s did not have elevators. With the acceleration of the aging population and the improvement of residents’ living standards, it will gradually become a common demand for the society to install elevators in old buildings. From the current market In terms of demand, although the calls for installing elevators in old buildings are getting louder, the difficulty is still not small. For an ordinary residential building, low-, middle-, and high-rise residents have different interests and standpoints. The installation cost is relatively high, and residents are unwilling to spend huge sums of money to install elevators, so there will be a funding gap for installing elevators. At present, most elevator...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a safety elevator with double traction machines for use outside old residential buildings, to solve the problem that existing elevators used outside old residential buildings use a single traction machine. When the elevator is running, it will affect the normal operation of the elevator, and even an accident will endanger the safety of passengers. When the car squats, the buffer on the base is used for buffering. The buffering effect is poor, and there are potential safety hazards. The possibility that it is easy to cause equipment damage
