Description
Technical field
The utility model relates to crane field, particularly relates to a kind of crane hook.
Background technology
Suspension hook is modal a kind of suspender in elevator machinery.Because the workplace danger coefficient of suspension hook is higher, if cable wire comes off from suspension hook, easily accidents caused, in Long-Time Service process, the inwall of suspension hook easily weares and teares, and the intensity of suspension hook is reduced, affects service life; Not easily, therefore seek a kind of cable wire difficult drop-off, suspension hook inwall is not easy to wear in existing suspension hook processing and manufacturing simultaneously, ensures that the suspension hook in service life is particularly important.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of crane hook.
The utility model is achieved through the following technical solutions:
A kind of crane hook, comprise hook, the upper end of described hook is connected to the lower end of erection column, and in the upper end of described erection column, positioning boss is installed, in the upper end of described positioning boss, joint pin is installed, the upper end of described joint pin is provided with davit, and runs through at the outer cylinder surface of described davit and offer mounting hole; The depressed part inwall of described hook is provided with wearing layer.
As optimal technical scheme of the present utility model, described erection column is connected by transition arc with between positioning boss.
As optimal technical scheme of the present utility model, the diameter of described erection column is larger than the diameter of positioning boss.
As optimal technical scheme of the present utility model, the upper end of described davit has chamfering.
As optimal technical scheme of the present utility model, described wearing layer adopts nickel-chromium material to make, and its thickness is 10mm-20mm.
Compared with prior art, the beneficial effects of the utility model are: hook is arranged on the lower end of joint pin, erection column by the utility model, and be provided with positioning boss, be convenient to processing and manufacturing, depressed part at hook is provided with wearing layer simultaneously, the inwall of hook can be prevented to be worn, to improve the service life of suspension hook.
