Adjustable floating contact type chain fracture warning protection device of parking equipment

Abstract

The invention discloses an adjustable floating contact type chain fracture warning protection device of parking equipment. The adjustable floating contact type chain fracture warning protection deviceof the parking equipment comprises a microswitch, an elastic driving regulating assembly, a first triangular plate and a second triangular plate, wherein the microswitch is arranged on a base; the elastic driving regulating assembly is arranged at the bottom of the base; one end of an elastic component is abutted against the bottom of the first triangular plate; a fastening screw is arranged at the lower part of the elastic component; the torsion pressure of the first triangular plate is regulated by regulating the screw; one side of the bottom of the first triangular plate is connected withthe base through a pin shaft; the upper part of the first triangular plate is connected with the second triangular plate through a pin shaft; one side edge of the second triangular plate abuts a roller of a vertically installed chain or a horizontally installed chain in a floating contact mode; a hinge extension pin shaft just presses a microswitch reed; when a chain in vertical arrangement or horizontal arrangement fractures or abnormally loosens, the chain falls down through self weight; the second triangular plate jacks away from the pressed microswitch reed under the effects of the first triangular plate and the elasticity; a signal is triggered; and a motor circuit is switched off. The adjustable floating contact type chain fracture warning protection device of parking equipment has the advantages that the reliability is high; and the device adapts to different installation precisions.

Description

technical field [0001] The invention relates to the technical field of chain breakage alarm protection for parking equipment, in particular to an adjustable floating contact type parking equipment chain breakage alarm protection device. Background technique [0002] Many parking devices are driven by chains. If the chain breaks suddenly during transmission without alarm, serious consequences will occur. The existing parking equipment chain transmission devices are required to be equipped with a broken chain alarm device, that is, when one or both sides of the chain breaks, the micro switch is triggered to send an alarm signal, and the power supply of the motor is cut off in time to stop the motor and avoid double The side chains were out of sync, causing the deck to tilt and smash the car. [0003] The garage chain breaking alarm devices are all below the horizontal chain, and a micro switch is set. By the self-weight of the chain after it is broken, it touches the micro sw...

Problems solved by technology

This method has obvious defects. First, the horizontal chain is long. If the broken part is not at the micro switch, the natural drop of the chain may not be able to touch the micro switch; the other is that the broken part is just at the micro switch It may also be affected by the elasticity of the broken chain. The chain just pops out of the position of the original micro switch, which will cause the chain to hang down without touching the micro switch.

Therefore, the current method of laying micro switches under the horizontally arranged chains as a broken chain alarm device is unreliable.
