Real-time chain fracture prevention safety lock

Abstract

The invention discloses a real-time chain fracture prevention safety lock which comprises a lifting chain, a chain fracture detection switch, a left upright column and a right upright column, wherein a left guide block and a right guide block are mounted on the left upright column and the right upright column respectively; a left oblique groove and a right oblique groove are formed in one side of the left guide block and one side of the right guide block respectively; a left sliding block and a right sliding block are mounted in the left oblique groove and right oblique groove in a sliding fit manner respectively; a row of toothed bars is mounted at one side of the left sliding block; a row of toothed bars is mounted at one side of the right sliding block; a left spring seat and a right spring seat are fixedly arranged at the tops of the left guide block and the right guide block respectively; springs are correspondingly connected between the left spring seat and the top end of the left sliding block and between the right spring seat and the top end of the right sliding block respectively; a left connecting rod and a right connecting rod are hinged to the bottom ends of the left sliding block and the right sliding block respectively; an electromagnet is arranged between the bottoms of the left upright column and the right upright column; the chain fracture detection switch is electrically connected with the electromagnet through a controller; a pull rod is hinged to the bottom ends of the left connecting rod and the right connecting rod; the bottom end of the pull rod extends to a place above an iron core of the electromagnet; and the pull rod is in clearance fit with the iron core. With the adoption of the structure, a comb-shaped rack and a vehicle on the comb-shaped rack can be protected effectively, and unnecessary accidents are precluded.

Description

technical field [0001] The invention relates to the field of comb-tooth tower parking equipment, in particular to a real-time chain-break prevention safety lock. Background technique [0002] Comb-tooth tower parking equipment is one of the commonly used parking equipment. Since there is no device for real-time protection of the lifting chain during operation, once the lifting chain is disconnected, the comb rack that is running or stationary in mid-air and the The continued fall of the comb frame with the load (vehicle) provides protection, which leads to the occurrence of safety accidents. Contents of the invention [0003] The object of the present invention is to provide a real-time anti-broken chain safety lock in order to overcome the defects and deficiencies in the prior art. [0004] Technical scheme of the present invention is as follows: [0005] A real-time anti-broken chain safety lock, comprising a lifting chain of a comb-toothed tower parking equipment, a c...
