Anti-collision device for lift accidental falling

Abstract

The invention discloses an anti-collision device for lift accidental falling. The anti-collision device for lift accidental falling comprises an upper pedestal, a hydraulic device, a fixed base, a screw hole, a rubber hose, a lower pedestal, an air bag, a first rubber hammer, a first hydraulic box, a hydraulic rod, a second hydraulic box, a second rubber hammer, a spring, a sponge pad and an air hole. The anti-collision device for lift accidental falling has the following beneficial effects: the hydraulic device is provided, and collision can be buffered by the hydraulic damping principle whenthe lift is collided, so that the lift and the passengers are protected; the spring is provided, so that collision can be buffered by the sponge pad and life and property safety can be protected; andthe air bag is provided, and during collision, the air bag suffers from pressure, a leather plug of the air hole is broken and the air bag is deflated, so that the anti-collision effect is achieved.The anti-collision device for lift accidental falling has complete functions and high protective property.

Description

technical field [0001] The invention relates to an anti-collision device, in particular to an anti-collision device for accidental landing of an elevator. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. Modern elevators are mainly composed of traction machine, guide rail, counterweight device, safety device, signal control system, car and hall door. These parts are respectively installed in the hoistway and machine room of the building. Steel wire rope friction transmission is usually used. The wire rope goes around the traction sheave, and the two ends are respectively connected to the car and the counterweight. The motor drives the traction sheave to lift the car up and down. The anti-collision device of the elevator is mainl...

Problems solved by technology

[0003] But existing anti-collision device still has certain defect when using, although existing anti-collision device can protect elevator and passenger, because existing elevator anti-collision device function is too single, protective measure is too few, effect is not very the obvious
