Description

Anti-falling device

Technical Field

The utility model relates to a parking equipment technical field, concretely relates to anti-falling device.

Background

With the rapid development of economy, the automobile holding amount is increased year by year, so that the supply and demand of parking spaces in a ground parking lot are insufficient, two layers or multiple layers of mechanical parking equipment are born, when vehicles are parked on or moved out of a parking platform by the mechanical parking equipment, a vehicle carrying plate (or a parking plate, also called an automobile carrier) is lifted and moved through a steel wire rope or a chain, but in the frequent lifting and use process of the vehicle carrying plate, the steel wire rope or the chain can break due to abrasion and the like to cause the sudden falling of the vehicle carrying plate, so that the risk of falling of the vehicles is generated.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an anti-falling device, this anti-falling device set up in mechanical type parking equipment's the four corners that carries the sweep, when going up and down with chain or lift wire rope breaking occur, anti-falling device can play the effect that prevents to carry the sweep and fall to avoid parking equipment to take place the incident.

The utility model provides a falling-proof device, which comprises a turnover stopping device and a triggering device;

the trigger device comprises a positioning piece, a pressing plate and a trigger piece; the positioning piece is used for being fixed with a vehicle carrying plate of the mechanical parking equipment, is positioned below the pressing plate and is connected with the pressing plate through a connecting piece; the positioning piece comprises a transverse plate parallel to the pressing plate, and the trigger piece is positioned below the transverse plate and arranged on the connecting piece;

the turnover stopping device comprises a turnover hook and a connecting rod, one end of the connecting rod is connected with the pressing plate, and the other end of the connecting rod is hinged with the turnover hook;

when a steel wire rope or a chain for lifting of the mechanical parking equipment is broken, the trigger part pulls the movable platen downwards to drive the connecting rod and the turnover hook to turn over.

Specifically, the positioning piece is fixedly connected with the connecting piece.

Among the above-mentioned anti-falling device, sweep fixed connection is carried with parking equipment to the setting element, carry the sweep by lift with wire rope or chain pulling, thereby make the setting element and trigger the piece and be in stable balanced state, when wire rope or chain fracture, the upward pulling force that the setting element received disappears, trigger the piece because of dead weight draws down the sweep, and then drive the certain angle of connecting rod and upset hook upset, the upset hook card is gone into in parking equipment's crossbeam or the roll table roof beam, thereby avoided parking equipment to carry the tenesmus of sweep, the incident of avoiding taking place the vehicle and falling.

Further, the trigger is a balancing weight.

When the steel wire rope or the chain of the parking equipment is broken, the counterweight block downwards moves due to self weight, and the pressing plate connected with the connecting piece is pulled to downwards move, so that the connecting rod and the turnover hook are driven to turn over to hook the cross beam or the roller way beam of the parking equipment.
