Abstract

The utility model provides a crane hook positioning device, which comprises a bottom plate, a pin shaft, an ear plate, a positioning rod, a positioning plate and a bolt; four clamping grooves are arranged on the outer circumference of the circular positioning plate at equal intervals, and the positioning plate is connected to a hook handle at the lower part of the cross beam through a central shaft hole; the bottom plate both sides are equipped with the otic placode, and "L" shape locating lever upper end is through round pin hub connection on the otic placode, and the end card is stretched out to the locating lever lower part in the locating plate draw-in groove, and the bottom plate passes through the bolt fastening in one side of lifting hook crossbeam. The utility model discloses can reliably fix a position when needs gib head is fixed towards the operation, wear and tear and the accident that drops appear when effectively preventing the gib head from rotating, when guaranteeing hoisting equipment safety work, reduce the fault rate, eliminate the potential safety hazard, ensure the person and equipment safety.

Description

A kind of crane hook registration device

Technical field

The utility model belongs to the lifting equipment field, relates in particular to a kind of registration device for the crane hook assembly pulley.

Background technology

Crane hook assembly pulley registration device is the vitals of crane safety, stable operation.But find in actual use, this registration device exists the phenomenon that location is unreliable, easy to wear, easily drop, and has not only lost the positioning function of lifting hook pulley group, has increased the fault rate of equipment; And exist greatly potential safety hazard, threaten the person and device security.

Summary of the invention

The utility model aims to provide a kind of simple in structure, and location is reliable, can effectively prevent from when gib head from rotating occurring the crane hook registration device of wearing and tearing and the accident that drops.

For this reason, the solution that the utility model is taked is:

A kind of crane hook registration device, is characterized in that, base plate, bearing pin, otic placode, radius stay, locating plate and bolt, consists of; Have four draw-in grooves in circular locating plate excircle equal intervals, locating plate is connected on the neck of hook of crossbeam bottom by central shaft hole; The base plate both sides are provided with otic placode, and " L " shape radius stay upper end is connected on otic placode by bearing pin, and radius stay bottom external part is stuck in the locating plate draw-in groove, and base plate is bolted on a side of lifting beam with hook.

The beneficial effects of the utility model are:

The utility model suspension hook registration device can reliably be located when the needs gib head is fixed towards operation, effectively prevents from when gib head from rotating occurring wearing and tearing and the accident that drops, when guaranteeing the weight-lifting equipment trouble free service, reduce the hoisting crane fault rate, eliminate safe hidden trouble, guarantee the person and device security.
