A hook with optimized structure on a crane

Abstract

The invention discloses a crane lifting hook with an optimized structure. The crane lifting hook comprises an inverted M shaped hook body; the hook body is composed of hook claws on the two sides anda middle vertical part; the upper end of the middle vertical part is fixedly provided with a cylindrical blocking block; the upper end of the cylindrical blocking block is provided with a vertical screw bolt; the top end of the vertical screw bolt is fixedly connecting with a connecting block; support lugs are formed on the two side walls of the middle vertical part below the blocking block; the support lugs are connected with articulated shafts through hinge joint; the two ends of each articulated shaft is connected with one ends of two blocking rods respectively, the other ends of the two blocking rods are fixedly connected with a connecting rod; each connecting rod is pressed against the external wall of a corresponding hook claw on the hook body; a guide groove is formed on each blocking rod; a guide shaft is arranged between each of blocking rods, the two ends of each guide shaft are provided with support columns, and the support columns are inserted into the guide grooves of theblocking rods; the vertical screw bolt is sleeved with an adjusting sleeve; the side wall of the adjusting sleeve is provided with supporting rods; the lower end of each supporting rod is fixed by guide shaft inserting; the adjusting sleeve is connected with a screw sleeve through hinge joint; and the vertical screw bolt is sleeved the screw sleeve. The crane lifting hook is capable of avoiding lifting hook unhooking, and is convenient for steel rope to pass through the crane lifting hook or to be detached from the crane lifting hook.

Description

Technical field: [0001] The invention relates to the technical field of engineering machinery, and more specifically relates to a structure-optimized suspension hook on a crane. Background technique: [0002] With the rapid development of large-scale infrastructure construction, energy industry, shipbuilding industry and other industries in recent years, it has greatly promoted the development of heavy machinery manufacturing industries such as cranes. During the process, due to external factors such as wind, the wire rope of the crane shakes, which is prone to decoupling, causing casualties, damage to goods and other adverse consequences; thus, some cranes are equipped with internal baffles that can rotate on the hook. The force of the inner stopper against the inner wall of the hook head by the force of the spring or torsion spring, although the structure facilitates the entry of steel cables into the hook, but because the inner stopper is set on the inside of the hook, it...

[0002] With the rapid development of large-scale infrastructure construction, energy industry, shipbuilding industry and other industries in recent years, it has greatly promoted the development of heavy machinery manufacturing industries such as cranes. During the process, due to external factors such as wind, the wire rope of the crane shakes, which is prone to decoupling, causing casualties, damage to goods and other adverse consequences; thus, some cranes are equipped with internal baffles that can rotate on the hook. The force of the inner stopper against the inner wall of the hook head by the force of the spring or torsion spring, although the structure facilitates the entry of steel cables into the hook, but because the inner stopper is set on the inside of the hook, it is necessary to place the inner stopper Turning down, sometimes the inner block will be hindered by the steel cable, which is very inconvenient to turn down, and it is very inconvenient to take out the steel cable from the hook
