For achieving the above object, this utility model following technical scheme of offer: a kind of lift car buffer unit, including lift car and buffer unit, described buffer unit is located at the bottom of elevator, and lift car is arranged on the top of buffer unit, the top of described buffer unit is installed with acceleration induction device, and acceleration induction device is located at the inside of buffer unit, cushion it is installed with further below at acceleration induction device, described cushion air bag is installed further below, at air bag lower surface, hydraulic means is installed, in the outside of hydraulic means, hydraulic pressure holding vessel is installed, pressure valve and unidirectional gravity force gravity flow valve it is separately installed with bottom described hydraulic pressure holding vessel, described pressure valve and unidirectional gravity force gravity flow valve are directly connected to hydraulic means.
Preferably, the bottom of described hydraulic means is provided with pressure transducer.
Preferably, the side of described air bag is installed with compressor, and the opposite side at air bag is connected with hydraulic pressure holding vessel by buffer gas recovery tube.
Preferably, the seam of described gas recovery pipe is provided with unidirectional semipermeable membrane.
Preferably, described elevator bottom side is provided with control pressurer system.
Compared with prior art, the beneficial effects of the utility model are: use fluid as buffer medium, it is simultaneously introduced the real-time monitoring of elevator correlation behavior, thus the size of the cushioning effect power produced in Self Adaptive Control buffering course, before formal buffering, first pass through cushion and air bag, cut down overload impact power, realize the buffering effect that lift car is mild, it is effectively reduced the passenger's personal injury caused due to overload impact, on the other hand oil pollution can then be stopped, it is beneficial to environmental protection, can be widely used for the elevator buffer device repacking of various model, cost of investment is little, production technology is simple, there is certain society generalization be worth, and the recovery technology used, can effectively save energy resource consumption.
