Solid garage falling protector

Abstract

The invention relates to a solid garage falling protector. The falling protector is characterized in that one end of a pull rod is flexibly connected with an armature connector in a hinged mode, a fulcrum pin is fixed on a support, and the middle of a linkage lever is rotatablely matched with the fulcrum pin; one end of the linkage lever is flexibly connected with the other end of the pull rod in the hinged mode, the other end of the linkage lever is a flexibly connected with a connecting pin of a hook connector in the hinged mode, and the other end of the linkage lever is rotatablely connected to the connecting pin on the right upper part of the hook connector; and the support arranged on the left upper side of the hook connector is provided with a signal switch, and a trigger end of the signal switch is matched above the left upper side step of the hook connector. The pull rod of the falling protector provided by the invention is formed by connecting elastisch Oxford rods through the active linkage lever, therefore, the collision of the falling protector does not deform and bend through the collision. The falling protector provided by the invention has the advantages of restoration in time, good sensitivity, safety and waterproof properties, and prolongs the service life.

Description

Technical field: [0001] The invention relates to a fall arrester, in particular to a fall arrester for a three-dimensional garage. Background technique: [0002] The anti-drop device is an important safety component on the parking equipment, and it is mainly used to prevent the car-cutting board from accidentally falling when parking. The fall arrester in the prior art has the following defects: First, the connection between the electromagnet pull rod and the hook adopts a direct connection type. During transportation, once the hook is hit by a collision, it is easy to bend the electromagnet ejector rod, thereby causing the transmission to be stuck; The second is that after the electromagnet in the existing anti-fall device is energized for 5 minutes, the hook of the anti-fall device cannot be put in place due to the magnetic reduction caused by the temperature rise, and the safety performance of the anti-fall device is reduced; the third is that the original electromagnet u...

The fall arrester in the prior art has the following defects: First, the connection between the electromagnet pull rod and the hook adopts a direct connection type. During transportation, once the hook is hit by a collision, it is easy to bend the electromagnet ejector rod, thereby causing the transmission to be stuck; The second is that after the electromagnet in the existing anti-fall device is energized for 5 minutes, the hook of the anti-fall device cannot be put in place due to the magnetic reduction caused by the temperature rise, and the safety performance of the anti-fall device is reduced; the third is that the original electromagnet uses 180 Seconds later, the temperature reaches about 100 degrees, the utilization rate is 25%, the rated power is 75W, the energy consumption is high, the durability performance is 160,000 times, and the service life is short. It cannot be reset in time, the sensitivity is reduced, and the safety performance is reduced. Fifth, the original electromagnet has poor waterproof performance. When the air is humid, the electromagnet is prone to rust and corrosion, and the circuit is easy to age. Leakage shortens the service life of the electromagnet.
