CN202953711U - Self-lubricating type hook tile - Google Patents

Abstract

The utility model provides a self-lubricating formula hook tile, the determinant distributes at the circular arc middle part determinant of semi-circular hook tile has the graphite hole, inlays the graphite post in the graphite hole. During the process of charging iron and turning the tank by the crane, the graphite column is worn along with the hook tile, so that graphite particles enter between the hook tile and the tank shaft to play a role in lubrication. Thereby effectively slowing down the abrasion speed of the large hook tile, prolonging the service life of the large hook tile and reducing the spare part consumption and the expense. Meanwhile, the replacement frequency and workload can be reduced, and the operating rate of the crane is improved.

Description

A kind of self lubricating hook watt

Technical field

The utility model belongs to the mechanical equipment field, relates in particular to a kind of casting crane hook self lubricating hook watt used.

Background technology

Casting crane is important weight-lifting equipment, is mainly used in the ladle of handling splendid attire melt liquid or hot-metal bottle etc. in STEELMAKING PRODUCTION.Crane bottom hook is the major part of casting crane.Because casting crane is being converted iron and while turning over tank, large tank and the mutual friction of hook plate phase, cause the hook watt rate of wear to be accelerated, not only shortened the service life of hook watt, increased spare parts consumption and expense and paid; And, due to the frequent hook watt of changing, had a strong impact on the normal operation of crane.

Summary of the invention

The utility model aims to provide a kind of simple, can effectively slow down the rate of wear of hook watt, improves hook watt operating cycles, reduces the self lubricating hook watt of spare part expense.

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

A kind of self lubricating hook watt, is characterized in that, at the circular arc middle part determinant of semicircle hook watt, is distributed with graphite pores, inlays graphite column in graphite pores.

Described graphite pores adopts four lines four row formulas to distribute.

The beneficial effects of the utility model are:

Because graphite column has been inlayed in the circular arc middle part at hook watt, crane is in converting iron and turning over the tank process, and graphite column will be with hook watt wearing and tearing, and graphite granule is entered between hook watt and tank axle, plays lubricating effect.Thereby effectively slow down the rate of wear of hook watt, extend the service life of hook watt, reduce spare parts consumption and expense expenditure.Can reduce number of times and the work capacity of replacing, improve the operating rate of crane simultaneously.

The accompanying drawing explanation

Fig. 1 is self lubricating hook watt main cutaway view.

Fig. 2 is self lubricating hook watt birds-eye view.

In figure: hook watt 1, graphite column 2.

The specific embodiment

The cross sectional shape of hook of hoist watt 1 is a semicircle watt shape, is to adopt steel plate to process.The utility model is to be processed with four lines four row totally 16 graphite pores in the circular arc middle part of semicircle hook watt 1, and is inlaid with graphite column 2 in each graphite pores, thereby forms the hook watt 1 that can realize self-lubricating.

Claims (2)

1. a self lubricating hook watt, is characterized in that, at the circular arc middle part determinant of semicircle hook watt, is distributed with graphite pores, inlays graphite column in graphite pores.

2. self lubricating hook watt according to claim 1, is characterized in that, described graphite pores adopts four lines four row formulas to distribute.
