Abstract
An elevator buffering device provided with a safety air bag is composed of the safety air bag, an acceleration inductor, a control system, an air compressor, a one-way valve, a pressure inductor and an overflow valve, and is characterized in that the safety air bag is arranged in a bottom pit of a shaft of an elevator, and is provided with an air inlet valve and an air outlet valve in a matched mode, the acceleration inductor is arranged above the safety air bag to induce the acceleration variation information of a car of the elevator, one end of the control system is connected with the acceleration inductor, the other end of the control system is connected with the air compressor and the one-way valve to accept data signals of the acceleration inductor and send corresponding control signals to inflate the safety air bag, and a pressure control system is located under the safety air bag and is connected with the overflow valve to detect the pressure variation information of the safety air bag to control the overflow valve to move. The elevator buffering device provided with the safety air bag has the advantages that the air serves as the buffering medium, the relevant states of the elevator are monitored in real time, the buffering action force generated in the buffering process is controlled in a self-adaptation mode, overloading impact force is reduced, a smooth buffering effect of the car of the elevator is realized, the personal injury to passages caused by overload impact is effectively lowered, oil pollution is avoided, and environment protection is facilitated.
Description
Technical field
The present invention relates to a kind of elevator car safety, specifically a kind of have a safety air bag elevator buffer device.
Background technology
At present, known elevator pit shock absorber is to adopt direct press type pit shock absorber, and its shortcoming is: not only cushion stroke is little for direct press type elevator pit shock absorber, and cushion characteristic is poor, easily cause the lift car that falls because of stall to damage, and cause the injures and deaths of passenger in the lift car.
The invention technology
The object of the invention is to overcome above-mentioned deficiency, provide that a kind of impulsive force is little, stationarity good, can adaptive control safety air bag elevator buffer device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of have a safety air bag elevator buffer device, formed by safety air bag, acceleration induction device, control system, air compressor, check valve, pressure inductor, by pass valve, be primarily characterized in that: described safety air bag, it is located at the elevator hoistways pit, is equipped with the inlet and outlet valve; Described acceleration induction device is located at the safety air bag top, in order to respond to the acceleration change information of lift car; Described control system one end is connected with the acceleration induction device, and the other end is connected with check valve with air compressor, in order to the data-signal of accepting the acceleration induction device and send corresponding control signal to coming to airbag inflated; Described control pressurer system is located at the safety air bag below, and it links to each other with by pass valve, comes the controlling water kick valve events in order to detect safety air bag pressure variation information.
Further, described safety air bag and car size adapt to and are in same vertical axis position.
Advantage of the present invention: utilize gas as buffer medium, introduce simultaneously the Real-Time Monitoring of elevator correlation behavior, thereby the size of the buffer action power that produces in the adaptive control buffering course, cut down overload impact power, realize the mild buffering effect of lift car, effectively reduce because passenger's personal injury that overload impact causes then can be stopped oil pollution on the other hand, be beneficial to environmental protection.
