Description
Technical field
The utility model belongs to construction implement technical field, refers in particular to a kind of fall arrest construction elevator.
Background technology
In the construction of skyscraper; elevator can be built; upper and lower for personnel; but working elevator safety performance is generally poor, without fall arrest protection mechanism or fall arrest protection mechanism poor, design unreasonable; actual effect is undesirable; the domestic serious accident also occurring elevator falls several times, causes larger public opinion and the self-examination to construction safety, improves its safety performance so need badly in the use of elevator.
Summary of the invention
It is high that the purpose of this utility model is to provide a kind of safety performance, the fall arrest construction elevator preventing contingency from occurring.
The purpose of this utility model is achieved in that fall arrest construction elevator, comprise car, hoisting device and bracing frame, support frame as described above is provided with four guiding mobile jibs, described hoisting device is positioned at the top of support frame as described above, and connect car by hauling rope, described car is positioned at support frame as described above, and can move up and down along support frame as described above, wherein, four corners of described car are provided with falling proof device, described falling proof device comprises brake facing, electromagnetic drive mechanism and actuating mechanism, described brake facing is sheathed on described guiding mobile jib, described electromagnetic drive mechanism driving brake sheet holds described guiding mobile jib tightly, described actuating mechanism triggers described electromagnetic drive mechanism work.
According to upper described fall arrest construction elevator, wherein, described actuating mechanism comprises spring, suspension arm and startup pin, described suspension arm is fixed on described car, and described spring one end is connected with described suspension arm, the other end with described start to sell be connected, described startup pin is plugged on described electromagnetic drive mechanism, when described startup pin departs from described electromagnetic drive mechanism, trigger the switch of described electromagnetic drive mechanism, make it start working.
According to upper described fall arrest construction elevator, wherein, described spring is in nature suspension status or extended state, and when car drops, the acceleration/accel of moment can make described spring be stretched, spring after stretching starts resilience, drive described startup to sell and depart from described electromagnetic drive mechanism, described electromagnetic drive mechanism is triggered, and starts working, driving brake sheet completes emergency braking, prevents from falling.
According to upper described fall arrest construction elevator, wherein, described electromagnetic drive mechanism is also provided with hand switch, described hand switch extends in described car, when actuating mechanism is surprisingly malfunctioning, starts described electromagnetic drive mechanism by hand switch, complete emergency braking, formulation double insurance mechanism, guarantees occupant safety.
According to upper described fall arrest construction elevator, wherein, described car bottom is provided with buffering pneumatic cushion, as last safeguard procedures, reduces casualty rate.
The utility model gives prominence to compared to existing technology and useful technique effect is: when car weightlessness starts to fall, adopt the actuating mechanism work of loss-in-weight, open emergency braking, its structure is simple, highly sensitive, cost of manufacture is cheap, adopt double insurance mechanism in addition, in car, hand switch is installed, in case of emergency can enables hand switch, reduce the probability that car falls, guarantee passenger life safety; By buffering pneumatic cushion as final preventing mechanism, the casualty rate caused after reduction car lands.
