Anti-falling device of tightening element of small box fastener for electrolytic aluminum multifunctional crown block

Abstract

The invention relates to an anti-falling device of a tightening element of a small box fastener for an electrolytic aluminum multifunctional crown block and belongs to the technical field of the electrolytic aluminum multifunctional crown block. The anti-falling device of the tightening element of the small box fastener for the electrolytic aluminum multifunctional crown block comprises a fastener tightening base, a folding and unfolding connecting rod and an arm type grab plate, wherein the fastener tightening base is slidably connected with one end of the arm type grab plate through the folding and unfolding connecting rod while the other end of the arm type grab plate is slidably connected with the fastener tightening base; a hook plate slot is formed in a connected part of the folding and unfolding connecting rod and the arm type grab plate; a groove for placing the small box fastener is formed on the hook plate slot; a sliding shaft lever is fixedly arranged on the fastener tightening base; the lower end of the sliding shaft lever is slidably connected with the folding and unfolding connecting rod through a double-lug moving main shaft sleeve; a pull ring is arranged at the upper end of the sliding shaft rod and is connected with the double-lug moving main shaft sleeve. The device provided by the invention is mainly applied to the electrolytic aluminum multifunctional crown block.

Description

technical field [0001] The invention relates to an electrolytic aluminum multifunctional crane small box jig twisting head part anti-dropping device, which belongs to the technical field of electrolytic aluminum multifunctional cranes. Background technique [0002] The multifunctional crane is a crane specially designed and manufactured to meet the production needs of the electrolytic workshop of the electrolytic aluminum plant. There is a set of anode screwing mechanism on the crane, which is specially designed for loading and unloading the small box of anode fixtures. Whether it is a domestic crane or an imported crane, their working principles are similar and there is not much difference. The work of the anode screwing mechanism The principle is: when unloading the small box fixture, when the screw head is inserted into the screw head of the fixture, a pair of fork plates with a U-shaped mouth withstand the fixture shaft, and when the fixture is gradually loosened, a stee...

AI Technical Summary

Problems solved by technology

Due to the long-term production process, both will be deformed or damaged, or the angle of the arc plate on the newly purchased small box fixture is inconsistent, which will cause the plate to be stuck, the card to not be placed, or the contact surface of the card to be placed If it is too small or too loose, the original function cannot play a firm role in card removal

When using the multi-functional crane to replace the anode, the phenomenon of clamps suddenly falling off and hurting people frequently occurs, which is more obvious and brings greater safety hazards to production.
