Abstract

The invention provides an excavator movable arm front fork axial movement and radial rotating prevention mechanism, and belongs to the technical field of engineering mechanical pin shaft connection stop mechanisms. The excavator movable arm front fork axial movement and radial rotating prevention mechanism is characterized in that a bucket rod assembly is movably hinged to a movable arm through a shaft, a clamping groove is formed in the position, protruding out of the outer circle of the plane of the outer portion of the movable arm, of the shaft, one end of a stop plate is clamped into the clamping groove, and the other end of the stop plate is fixed to the movable arm through bolts. The mechanism is simple in manufacturing process, easy to assemble and not prone to being failed in function, and axial movement and radial rotating of a front fork of the movable arm of an excavator are avoided.

Description

The mechanism of the anti-axial float of excavator swing arm front fork and radial rotating
Technical field
The present invention relates to the mechanism of the anti-axial float of a kind of excavator swing arm front fork and radial rotating, belong to engineering machinery pin shaft joint stop mechanism technical field.
Background technology
Machinery industry many employings pin shaft joint stop mechanism, due to the improper operation of long high load capacity work and operator thereof, excavator swing arm front fork place very easily causes axial float and front fork axial deformation thereof, cause the various forms of inefficacy of swing arm, also the system of anti-axial float is had in existing excavator, but due to its design form, very easily cause thrashing because of bolt falling.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides the mechanism of the anti-axial float of a kind of excavator swing arm front fork and radial rotating, avoid excavator swing arm front fork axial float and radial rotating.
The technical solution used in the present invention is: the mechanism of the anti-axial float of a kind of excavator swing arm front fork and radial rotating, comprises dipper assembly, axle, swing arm, check plate, bolt; Described axle by dipper assembly and swing arm hinged actively, the cylindrical that aixs cylinder goes out swing arm outer surface level is shaped with draw-in groove, and one end of check plate is connected in draw-in groove, and other end bolt and swing arm are fixed together.
Beneficial effect of the present invention is: manufacture craft is simple, and easily assemble, function not easily lost efficacy, and avoided excavator swing arm front fork axial float and radial rotating.
