Description

Three joint arms excavate charging crane
Technical field
The utility model relates to the excavation charging crane, is specifically related to a kind of three joint arms and excavates charging crane.
Background technology
Existing excavation charging crane comprises power car, is hinged with swing arm on the power car, is hinged with dipper on the swing arm, is hinged with bucket on the dipper; Be hinged with the boom cylinder that drives the swing arm action on the power car, be hinged with the bucket arm cylinder that drives the dipper action on the swing arm, be hinged with the bucket cylinder that drives the bucket action on the dipper.The excavation charging crane of said structure is the arm-type excavation charging cranes of two joints, owing to have only two joint arms, promptly has only dipper and swing arm, thereby causes the sliding scale of bucket little, causes the scope of application narrow; For example in the compartment, unload coal or when other fragment, powder and granule shape material, grab bucket is difficult to come to the compartment wall, cause in the compartment material surplus more.
The utility model content
The technical problem that the utility model will solve is to above-mentioned deficiency, provides three big joint arms of a kind of bucket scope of activities to excavate charging crane.
In order to solve the problems of the technologies described above; The utility model provides a kind of three joint arms of following structure to excavate charging crane; Comprise power car, swing arm and dipper; Its design feature is to be provided with intermediate arm between swing arm and the dipper, and the rearward end section of swing arm front end and intermediate arm is hinged, and the rearward end section of dipper and the front end of intermediate arm are hinged; The bucket arm cylinder of the driving dipper action that is hinged with on the intermediate arm, the intermediate arm oil cylinder of the driving intermediate arm that is hinged with on swing arm action.
Said power car is wheeled or the crawler type power car.
The utility model through between swing arm and dipper, establishing these technical measures of intermediate arm, just can be realized the goal of the invention that the bucket scope of activities is big on the basis of existing technology.Thereby, the utlity model has simple in structurely, the advantage that the bucket scope of activities is big can be brought and excavate the wide beneficial effect of the charging crane scope of application.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; Three joint arms excavate charging crane and comprise power car 1, swing arm 2 and dipper 3, and above-mentioned power car 1 does not have essence different with the power car that existing two-segment type excavates charging crane, is prior art; Its structure is well known to those skilled in the art; Repeat no more at this, said power car 1 is wheeled or the crawler type power car, and shown in the figure is the crawler type power car.Swing arm 2 hinges are contained on the power car 1, are provided with intermediate arm 4 between swing arm 2 and the dipper 3, and the rearward end section of swing arm 2 front ends and intermediate arm 4 is hinged, and the rearward end section of dipper 3 and the front end of intermediate arm 4 are hinged, and the front end of dipper 3 is hinged with bucket 8.Be hinged with the boom cylinder 7 that orders about swing arm 2 actions on the power car 1; The intermediate arm oil cylinder 6 of driving intermediate arm 4 actions that are hinged with on the swing arm 2; The bucket arm cylinder 5 of driving dipper 3 actions that are hinged with on the intermediate arm 4, the bucket cylinder 9 of driving bucket 8 actions that are hinged with on the dipper 3.The connected mode of above-mentioned each oil cylinder is following: the cylinder body of boom cylinder 7 and power car 1 are hinged, and its piston rod and swing arm 2 are hinged; The cylinder body of intermediate arm oil cylinder 6 and swing arm 2 are hinged, and its piston rod and intermediate arm 4 are hinged; The cylinder body of bucket arm cylinder 5 and intermediate arm 4 are hinged, and its piston rod and dipper 3 are hinged; The cylinder body of bucket cylinder 9 and dipper 3 are hinged, and its piston rod and bucket 8 are hinged.
