Abstract

The utility model discloses a crown block hook which comprises a hook cap and a hook head, wherein one end of the hook cap is in a closed triangle shape; a hollow hole is formed in the uppermost end of the triangle; the other end of the hook cap is in a rectangle shape; more than two round holes which are centrally symmetric relative to a rectangle end are formed in the rectangle end; a connection device is arranged at two round holes which are centrally symmetric relative to the rectangle end; an elliptical hole for accommodating a connection device is formed in the uppermost end of the hook head; the connection device at the round holes of the hook cap and the connection device at the elliptical hole are connected with the hook cap and the hook head through an iron chain; and the iron chain comprises a plurality of rings. The crown block hook has the benefits as follows: when a steel ring is transmitted, the connection device of the two symmetric holes of the hook cap can be moved according to different diameters of the steel ring, the distance between two hook pieces of the hook cap is regulated further, the transmission process is safer, and the steel ring is prevented from falling off. Besides, the crown block hook has the advantages of simple structure, convenience in maintenance, high working efficiency and the like.

Description

A kind of crown block hook
Technical field
The utility model belongs to mechanical engineering suspender field, especially relates to a kind of crown block hook.
Background technology
Color coil of strip and steel coil strip are indispensable production materials in manufacturing, work progress at steel structure, the color coil of strip of entire volume or the weight of steel coil strip weigh several tons, in prior art, the suspender that there is no special handling, the color coil of strip of loading and unloading and steel coil strip, all to adopt extension steel rope under common suspension hook to lift by crane color coil of strip and steel coil strip in production scene, because their monomer weight is huge and steel rope is thinner, during lifting, the inner ring of steel coil two ends are stressed excessive, steel rope can form incised wound to coil of strip, causes the unnecessary loss of coil of strip.
Summary of the invention
The purpose of this utility model is to provide a kind of crown block hook of simple in structure, easy to operate, high efficiency, especially is fit to the transmission of steel ring.
the technical solution of the utility model is: a kind of crown block hook, comprise hook cap and gib head, one end of described hook cap is the triangle end of sealing, and triangle end centre portion topmost is equipped with hollow hole, the other end of the hook cap end that is rectangle, and the oblong end is provided with the relative centrosymmetric circular hole of oblong end more than two, be provided with connecting device on relatively centrosymmetric two circular holes of oblong end, the top of described gib head is provided with the slotted eye that can place connecting device, connecting device on connecting device on the circular hole of hook cap and the slotted eye of gib head reaches being connected of hook cap and gib head by iron chains, described iron chains is comprised of several rings.
Further, described connecting device is demountable structure.
Advantage and good effect that utility model has are: owing to adopting technique scheme, when transmitting steel ring, can be different according to the diameter of steel ring, the connecting device of two symmetrical circular holes of movable hook cap, and then the distance of having regulated two hook sheets, make transport process safer, better prevented from coming off.But also have the advantages such as simple in structure, easy to maintenance, easy to operate, that work efficiency is high.

The specific embodiment
As shown in Figure 1,
the technical solution of the utility model is: a kind of crown block hook, comprise hook cap 1 and gib head 2, one end of described hook cap 1 is the triangle end 3 of sealing, and triangle end 3 centre portion topmost is equipped with hollow hole 4, the other end of hook cap 1 is rectangle and holds 5, and oblong end 5 is provided with the relative centrosymmetric circular hole 6 of oblong end 5 more than two, be provided with connecting device 7 on relatively centrosymmetric two circular holes 6 of oblong end 5, the top of described gib head 2 is provided with the slotted eye 8 that can place connecting device 7, connecting device 7 on connecting device 7 on the circular hole 6 of hook cap 1 and the slotted eye 8 of gib head 2 reaches being connected of hook cap 1 and gib head 2 by iron chains 9, described iron chains 9 is comprised of several rings.
During this example was implemented, described connecting device 7 was demountable structure.
The working process of this example: when transmitting steel ring, can be different according to the diameter of steel ring, connecting device 7 on 1 two symmetrical circular holes 6 of movable hook cap, and then the distance of having regulated two gib heads 2, make transport process safer, better prevented from coming off.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
