Abstract

The utility model discloses a balance arm device of a crane, which relates to hoisting machinery, and solves the problem that a conventional balance arm device is high in cost. The balance arm device comprises a balance arm and a shaft connected with the balance arm, and is characterized in that a self-lubricating shaft sleeve is additionally arranged between the balance arm and the shaft and is fixed with the balance arm through a fastening screw. The balance arm device of the crane is used for a lifting mechanism of the crane and has the advantages of low production cost and simple manufacturing technology.

Description

A kind of balance arm device of hoisting crane

Technical field

The utility model relates to elevator machinery, particularly a kind of balance arm device of crane hoisting mechanism

Background technology

At present, in lifting mechanism with balance arm device, for actv. reduces the friction of equilibrium arm swing process, in the junction of equilibrium arm and axle, install an oscillating bearing additional, reduce the friction of equilibrium arm and axle by oscillating bearing, because oscillating bearing purchase cost is high, increased the object cost of product.

Utility model content

The purpose of this utility model is intended to overcome the shortcoming that prior art exists, and a kind of balance arm device of hoisting crane is provided, and solves the high technical matters of existing balance arm device cost.

The utility model is achieved through the following technical solutions:

A balance arm device for hoisting crane, comprising: equilibrium arm, the axle being connected with equilibrium arm; It is characterized in that: between described equilibrium arm and described axle, install self lubrication bearing additional, described self lubrication bearing is fixed by holding screw and described equilibrium arm.

The utility model compared with prior art, owing to adopting self lubrication bearing to replace expensive oscillating bearing, not only greatly reduces cost of product, and has simplified manufacture craft.The utility model, for the lifting mechanism of hoisting crane, has productive costs low, the simple advantage of manufacturing process.
