Abstract
The utility model discloses a mechanism for preventing axial movement and radial rotation on a front fork of a movable arm of an excavator. The mechanism comprises a bucket rod assembly, the movable arm, a shaft, a shim plate, a stop block and a stop seat; the shaft is arranged on the bucket rod assembly; the shim plate is assembled between the step end of the shaft and the movable arm; and the stop block is inserted into the stop seat, sleeved at the other end of the shaft and connected and fixed through a bolt and a nut. The utility model has the advantages that the mechanism is easy to manufacture and easy to assemble, the function of the mechanism is difficult to lose, and the axial movement and the radial rotation of the front fork of the movable arm of the excavator are avoided.
Description
Technical field
The utility model relates to the mechanism of the anti-axial float of a kind of excavator swing arm front fork and radial rotating, belongs to the engineering machinery bearing pin and connects the stop mechanism technical field.
Background technology
Machinery industry adopts bearing pin to connect stop mechanism more, because 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, causes the various forms of inefficacies of swing arm.The system that anti-axial float is also arranged in the existing excavator, but because its design form very easily causes thrashing because of bolt falling.
Summary of the invention
For the problem that above-mentioned prior art exists, the mechanism that the utility model provides the anti-axial float of a kind of excavator swing arm front fork and radial rotating avoids excavator swing arm front fork axial float and radial rotating.
To achieve these goals, the technical solution adopted in the utility model is: the mechanism of the anti-axial float of a kind of excavator swing arm front fork and radial rotating comprises dipper assembly, swing arm, axle, backing plate, scotch and stop-motion seat; Axle is installed on the dipper assembly, is equipped with backing plate between pillow block rank end and the swing arm, and scotch inserts stop-motion seat and is inserted in the other end of axle, and is connected and fixed by bolt and nut.
The beneficial effects of the utility model are: manufacture craft is simple, easily assembling, and function is difficult for losing efficacy, and has avoided excavator swing arm front fork axial float and radial rotating.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model sectional view;
Fig. 3 is the connecting axle structure schematic diagram;
Fig. 4 is scotch structure enlarged diagram.
Among the figure: 1, dipper assembly, 2, swing arm, 3, axle, 4, backing plate, 5, scotch, 6, bolt and nut, 7, stop-motion seat.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4: the utility model comprises dipper assembly 1, swing arm 2, axle 3, backing plate 4, scotch 5 and stop-motion seat 7, axle 3 is installed on the dipper assembly 1, be equipped with backing plate 4 between axle 3 step ends and the swing arm 2, scotch 5 inserts stop-motion seat 7 and is inserted in the other end of axle 3, and is connected and fixed by bolt 6.
In the installation process, backing plate 4 is inserted in axle 3, then axle 3 is inserted swing arm from upper end shown in Figure 2, the swing arm dipper is linked together, until axle 3 exposes suitable distance from Fig. 2 lower end; Scotch 5 is inserted stop-motion seat 7 and is inserted in axle 3; Axle 3 is assembled to the end, bolt and nut 6 assemblings are finished.The utility model is applicable to the construction machinery industry bearing pin and connects stop mechanism, prevents bearing pin axial float and radial rotating.
