Automatic opening and closing type anti-falling lifting hook device used for hoisting machinery

Abstract

The invention discloses an automatic opening and closing type anti-falling lifting hook device used for hoisting machinery, and relates to the technical field of lifting hooks. The problem that the optimal design of an anti-release structure of a hook connecting component of an existing anti-falling lifting hook is not ideal enough, consequently, the lifting hook is prone to being disassembled inair during splicing and use, and a hoisted object has a relatively large hidden danger of shaking and falling are solved. The automatic opening and closing type anti-falling lifting hook device used for the hoisting machinery comprises hook bodies, each hook body comprises a rail strip, a positioning frame, positioning short shafts and a blocking frame, and the two hook bodies are spliced to forma double-lug lifting hook. The two corresponding positioning short shafts are symmetrically welded to the top end section of each of the two hook bodies, and the two positioning short shafts on the left side are each provided with a hook plate in a sleeved and rotating manner. Steel wire lifting ropes penetrate through semicircular clamping plates, the semicircular clamping plates can drive sliding frames and ejector blocks to slide upwards through the up-lifting force of the steel wire lifting ropes, and therefore the trouble that the ejector blocks are ejected and pushed to slide upwards through manual force is omitted.

Description

technical field [0001] The invention relates to the technical field of hooks, in particular to an automatic opening and closing anti-dropping hook device for hoisting machinery. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. The hook is the most common type of spreader in hoisting machinery. The hook is often suspended on the wire rope of the hoisting mechanism by means of a pulley block and other components. Hooks are widely used in ports, electric power, steel, shipbuilding, petrochemical, mining, railway, construction, metallurgy and chemical industry, automobile manufacturing, plastic machinery, industrial control, highway, large-scale transportation, pipeline auxiliary construction, slope tunnel, shaft treatment Protection, sea rescue, marine engineering, airport construction, bridges, aviation, aerospace, venues and other important industries and infr...

Problems solved by technology

[0005] The object of the present invention is to provide an automatic opening and closing type anti-off hook device for hoisting machinery, to solve the unsatisfactory optimization design of the anti-trip structure of the hook connecting parts proposed in the above-mentioned background technology, resulting in a When splicing is used, it is easy to disintegrate in the air, causing the lifting objects to have a greater risk of shaking and falling
