Abstract
The utility model relates to the excavator technical field, especially to a two-segment elongated arm of an excavator. The two-segment elongated arm comprises a large arm and a small arm, wherein the rear end of the large arm is hinged to the front end of the small arm, installing plates are respectively fixed on the rear end of the large arm, an articulated shaft is connected between the two installing plates, hinge holes are arranged at the front end of the small arm, the front end of the small arm extends between the two installing plates, and the hinge holes are rotatably connected to the articulated shaft. Two-segment elongated arm, a large arm and a small arm, is used in stead of a conventional integral working arm, which provides more interchangeable working devices and substantially improves the versatility of the two-segment elongated arm. Working dimension and excavation capacity of the excavator can be adjusted at will according to actual situation. Moreover, the two-segment elongated arm has a stable structure and prolongs the service lifetime of an excavator.
Description
Technical field:
The utility model relates to the excavator technical field, relates in particular to a kind of excavator two-section extension arm.
Background technology:
Excavator is to excavate with scraper bowl to be higher or lower than the material that holds machine side, and the haulage vehicle or unload the earth moving plant to rickyard of packing into.The material that excavates mainly is soil and the rock behind soil, coal, silt and the preparatory pine of process.From the development of engineering machinery in recent years, the development of excavator is very fast relatively, and excavator is as one of topmost engineering machinery type in the engineering construction.The excavator working arm is as the important component part of excavator; Directly have influence on the operation size and the digging force of excavator, working arm all adopts monolithic in the prior art, and its shortcoming is that the equipment of changing is few; Versatility is relatively poor, is used on the similar excavator of long-term operating condition more.The monolithic working arm can not make excavator obtain bigger excavation depth, is not suitable for general excavator.
The utility model content:
The purpose of the utility model be exactly the deficiency that exists to prior art and provide a kind of simple in structure, versatility good and can arbitrarily adjust the excavator two-section extension arm of operation size and digging force according to actual conditions; When guaranteeing excavation depth, do not influence and unload the soil height.
To achieve these goals, the technical scheme of the utility model employing is:
Excavator two-section extension arm, it includes big arm and forearm, and the rear end of big arm and the front end of forearm are hinged; Wherein, The both sides of big arm rear end are fixed with installing plate respectively, are connected with jointed shaft between two installing plates, and the front end of forearm offers hinge hole; the front end of forearm stretches between two installing plates, and hinge hole is rotatably connected on the jointed shaft.
Pass through Driven by Hydraulic Cylinder between said big arm and the forearm.
Said big arm and forearm are hollow box body shape structure.
Said big arm is provided with bearing pin.
The front end edge bearing pin position of said big arm is bent to form the bending structure downwards.
The material of said big arm, forearm is Q345B or HG785.
The utility model beneficial effect is: the utility model includes big arm and forearm, and the rear end of big arm and the front end of forearm are hinged, wherein; The both sides of big arm rear end are fixed with installing plate respectively, are connected with jointed shaft between two installing plates, and the front end of forearm offers hinge hole; the front end of forearm stretches between two installing plates, and hinge hole is rotatably connected on the jointed shaft big arm of the utility model utilization and forearm formation two-section extension arm; replace monolithic working arm of the prior art; it is many that it exchanges equipment, improved its versatility greatly, and can arbitrarily adjust the operation size and the digging force of excavator according to the needs of actual conditions; and structure is firm, has prolonged the application life of excavator.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the partial sectional view of the utility model.
Fig. 3 is the structural representation of the utility model forearm.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, sees shown in Fig. 1～3, excavator two-section extension arm; It includes big arm 1 and forearm 2, and the rear end of big arm 1 and the front end of forearm 2 are hinged, wherein; The both sides of big arm 1 rear end are fixed with respectively between 3, two installing plates 3 of installing plate and are connected with jointed shaft 4, and the front end of forearm 2 offers hinge hole 21; front end of forearm 2 stretches between two installing plates 3, and hinge hole 21 is rotatably connected on the jointed shaft 4.
Drive through the hydraulic cylinder (not shown) between big arm 1 and the forearm 2.Big arm 1 is hollow box body shape structure with forearm 2.Big arm 1 is provided with bearing pin 5, and front end edge bearing pin 5 positions of big arm 1 are bent to form the bending structure downwards, can obtain bigger excavation depth.
The material of big arm 1, forearm 2 is Q345B or HG785, and wherein the overlength extension arm can be used high-strength plate HG785, makes the thickness of slab attenuation, weight reduction, and load reduces, and has prolonged the application life of excavator.
The big arm 1 of the utility model utilization constitutes the two-section extension arm with forearm 2; Replace monolithic working arm of the prior art; It is many that it exchanges equipment, improved its versatility greatly, and can arbitrarily adjust the operation size and the digging force of excavator according to the needs of actual conditions; And structure is firm, has prolonged the application life of excavator; In addition, this structure can not only obtain bigger excavation depth, and can not have influence on the height that it unloads soil, thereby has improved excavation quality and productivity ratio.The utility model is applicable to underloading operating environments such as channel cleanout, trimming of slope, also is suitable for operating environments such as pan soil excavation and rubble loading.
Certainly, the above only is the preferred embodiment of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
