Abstract
The utility model relates to the technical field of an excavator, and particularly to a three-segment type lengthened arm of the excavator. The three-segment type lengthened arm of the excavator comprises a large arm, a middle arm and a small arm. Two ends of the middle arm are respectively hinged with the back end of the large arm and the front end of the small arm, wherein, two sides of the back end of the large arm are respectively provided with a first mounting plate fixedly. Two sides of the front end of the small arm are respectively provided with a second mounting plate fixedly. One end of the middle arm is hinged between the two first mounting plates, and the other end is hinged between the two second mounting plates. According to the three-segment type lengthened arm of the excavator, the three-segment type lengthened arm is composed of the large arm, the middle arm and the small arm. An integral operation arm in the prior art is replaced. Multiple exchangeable operation devices are provided. The versatility is greatly improved. Furthermore operation dimension and excavation force of the excavator can be randomly adjusted according to the requirement of practical situation. The three-segment type lengthened arm of the excavator further has the following advantages: longer operation distance, high suitability for detaching high-rise building, stable structure, and prolonged service life of the excavator.
Description
Technical field:
The utility model relates to the excavator technical field, relates in particular to a kind of excavator syllogic 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 syllogic 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 syllogic extension arm; It includes big arm, middle arm and forearm, and the two ends of middle arm are hinged with the front end of the rear end of big arm, forearm respectively, wherein; The both sides of big arm rear end are fixed with first installing plate respectively; the both sides of forearm front end are fixed with second installing plate respectively, and an end of middle arm is hinged between two first installing plates, and the other end of middle arm is hinged between two second installing plates.
Arm drives with big arm, forearm respectively through two hydraulic jacks and is connected in said.
Said two hydraulic jacks are arranged in arm the same side.
Said big arm is provided with bearing pin.
Said big arm, middle arm and forearm are hollow box body shape structure.
The material of said big arm, middle arm and forearm is Q345B.
The utility model beneficial effect is: the utility model includes big arm, middle arm and forearm, and the two ends of middle arm are hinged with the front end of the rear end of big arm, forearm respectively, wherein; The both sides of big arm rear end are fixed with first installing plate respectively, and the both sides of forearm front end are fixed with second installing plate respectively, and an end of middle arm is hinged between two first installing plates; The other end of middle arm is hinged between two second installing plates, and the big arm of the utility model utilization, middle arm and forearm constitute the syllogic 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; Has long operating distance; Be applicable to the dismounting operation of high-rise building, and structure is firm, has prolonged the application life of excavator.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Figure 1, excavator syllogic extension arm; It includes big arm 1, middle arm 2 and forearm 3, and the two ends of middle arm 2 are hinged with the front end of the rear end of big arm 1, forearm 3 respectively, wherein; The both sides of big arm 1 rear end are fixed with first installing plate 4 respectively; the both sides of forearm 3 front ends are fixed with second installing plate 5 respectively, and an end of middle arm 2 is hinged between two first installing plates 4, and the other end of middle arm 2 is hinged between two second installing plates 5.
In arm 2 drive and be connected with big arm 1, forearm 3 respectively through two hydraulic jacks 6.Two hydraulic jacks 6 are arranged in arm 2 the same sides.Big arm 1 is provided with bearing pin 7, and big arm 1, middle arm 2 and forearm 3 are hollow box body shape structure.The material of big arm 1, middle arm 2 and forearm 3 is Q345B.Be furnished with stop valve, hydraulic control one-way valve etc. on big arm 1, middle arm 2 and the forearm 3, for work high above the ground provides safety guarantee.
The big arm of the utility model utilization 1, middle arm 2 and forearm 3 constitute the syllogic extension arms, replace monolithic working arm of the prior art, and 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 have long operating distance, be applicable to the dismounting operation of high-rise building; And structure is firm, has prolonged the application life of excavator.Certainly, the utility model also is applicable to underloading operating environments such as channel cleanout, trimming of slope, and 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.
