Description

Crane hook

Technical Field

The utility model relates to a hoist field, in particular to crane hook.

Background

The crane is mainly used for different working occasions such as field hoisting, emergency rescue, stations, wharfs, narrow areas and the like to perform hoisting and hoisting operation. Cranes are among the most common devices, especially when loading and unloading goods at quay yards, and gantry cranes, automobiles, tires, and crawler cranes are all commonly used. The rubber-tyred crane has longer suspension arm, and is particularly suitable for stacking higher cargo stacks or loading and unloading ships.

The lifting hook is an important part for lifting cargos in the crane, because the lifting hook needs to lift different cargos, lifting hooks with different sizes or shapes are needed, referring to fig. 1, but the existing lifting hook S1 for the crane is directly connected to the connecting frame S2, cannot be detached or replaced, and therefore the universality is poor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a crane hook has solved current lifting hook that is used for the hoist and all is unable dismantlement and unable change, has the poor defect of commonality.

The technical scheme of the utility model is realized like this:

crane hook, including the lifting hook link, the lower extreme of lifting hook link is connected with trades the hook connecting plate, trades to be provided with the detachable lifting hook on the hook connecting plate, and the lifting hook includes horizontal support shaft, and the middle fixedly connected with gib head of horizontal support shaft lower extreme trades and sets up the logical groove that runs through both ends face from top to bottom on the hook connecting plate, leads to the groove and is used for horizontal support shaft to pass, trades the upper surface of hook connecting plate and offers and leads to the groove of arranging perpendicularly, and the recess is used for the support and the location of horizontal.

Further, the groove is an arc-shaped surface.

Further, the hook changing connecting plate is a rectangular plate or a circular plate.

Furthermore, the lifting hook connecting frame comprises two side plates and a plurality of pulleys rotatably connected to the side plates.

The utility model has the advantages that: the utility model discloses a lifting hook can be changed according to different needs, as long as upwards top gib head during the change, makes the horizontal support axle break away from the recess, then rotates gib head 90 degrees, makes horizontal support axle and logical groove coincidence, last downwardly moving gib head, and the horizontal support axle passes logical groove, and whole lifting hook has just taken off, and the process of installation is opposite, dismantles simple and conveniently.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 2-6, the crane hook comprises a hook connecting frame 1, the lower end of the hook connecting frame 1 is connected with a hook changing connecting plate 2, a detachable hook 3 is arranged on the hook changing connecting plate 2, the hook 3 comprises a horizontal supporting shaft 31, a hook head 32 is fixedly connected in the middle of the lower end of the horizontal supporting shaft 31, a through groove 21 which runs through upper and lower end faces is formed in the hook changing connecting plate 2, the through groove 21 is used for the horizontal supporting shaft 31 to pass through, a groove 22 which is vertically arranged with the through groove 21 is formed in the upper surface of the hook changing connecting plate 2, and the groove 22 is used for supporting and positioning the horizontal supporting.

Preferably, the groove 22 is an arc-shaped surface, so that the horizontal support shaft 31 can rotate smoothly along the groove 22.

Preferably, the hook changing connection plate 2 is a rectangular plate or a circular plate.

Preferably, the hook connecting frame 1 comprises two side plates 11 and a plurality of pulleys 12 rotatably connected to the side plates 11.

The utility model discloses a lifting hook 3 can be changed according to different needs, as long as upwards top gib head 32 during the change, makes horizontal support shaft 31 break away from recess 22, then rotates gib head 90 degrees, makes horizontal support shaft 31 and logical groove 21 coincidence, moves down gib head 32 at last, and horizontal support shaft 31 passes logical groove, and whole lifting hook 3 has just taken off, and the process of installation is opposite, dismantles simple and conveniently.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
