Description
Technical field
The invention belongs to engineering and material technology field, relate to a kind of engineering construction machinery, specifically is a kind of free style excavator, and this free style excavator can be applicable to boring and excavates.
Background technology
Excavator is claimed excavation machinery (excavating machinery) again, 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 excavator 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 has become one of topmost engineering machinery in the engineering construction.But under complex working condition; Traditional Work machine is because the impact direction of its impact head can only downwards or forward, the operation degree of freedom be less, thereby when carrying out construction operation; Flexibility is relatively poor relatively; Especially in the face of operating mode such as narrow, abominable the time, can't operate basically, significant limitation is arranged at accessibility first neighborhood.Therefore, it is better to study a kind of impact head flexibility, and the excavator that the impact direction flexibility ratio is big is that realistic meaning is arranged very much.
Summary of the invention
Defective or deficiency to above-mentioned prior art existence; The objective of the invention is to, a kind of free style excavator is provided, this excavator is through increasing one degree of freedom respectively at the big arm of excavator, forearm; Make impact head when carrying out construction operation; Flexibility improves greatly, especially in the face of operating mode such as narrow, abominable the time, is very beneficial for operation.
In order to achieve the above object, the present invention adopts following technical scheme:
A kind of free style excavator comprises first hydraulic motor, second hydraulic motor; Wherein, the big arm of first hydraulic motor and excavator is connected, thereby and drive first main axis rotation through the front end that first meshing gear connects first main shaft, first hydraulic motor is connected through spline with first meshing gear; First sleeve through the first load bearing be installed on first main shaft outside and 0 both to heart biserial, making the sleeve of winning can serve as the axle rotation with first main shaft, the rear end of first sleeve and center contiguous block spare are hinged; First barrel forward end is hinged with first hydraulic cylinder, and the other end of this first hydraulic cylinder and center contiguous block spare are hinged.
Second hydraulic motor and center contiguous block spare are connected, thereby and drive second main axis rotation through the front end that second meshing gear connects second main shaft, second hydraulic motor is connected through spline with meshing gear; Second sleeve through the second load bearing be installed on second main shaft outside and both to heart biserial, make that second sleeve can serve as the axle rotation with second main shaft, the rear end and the impact head of second sleeve are hinged; The front end of second sleeve is hinged with second hydraulic cylinder, and the other end and the impact head of this second hydraulic cylinder are hinged;
Hydraulic cylinder, first hydraulic motor, second hydraulic motor hinged on first sleeve and second sleeve all are connected to the control room main frame.
The present invention also comprises following other technologies characteristic:
The big arm of said first hydraulic motor and excavator is connected through bolt.
Said second hydraulic motor and center contiguous block spare are connected through bolt.
Advantage of the present invention is following: on the direction scope basis of the impact head of original excavator, increased by two rotary freedoms, these two rotary freedoms have significantly increased the working range of excavator, and the design through sleeve,
The big forearm of free style excavator has all increased by two brand-new degree of freedom, makes it to have very high freedom, and opereating specification is more extensive, and can impact with it is all directions at center, and its flexible performance has met or exceeded the flexible performance of common mechanical arm; It can realize that multi-angle impacts to same operand, to reach the purpose of destroying fully, also can be difficult to impact at general excavator, impact in the inconvenient operating mode of freely advancing, rotating; Simultaneously, for adapting to dangerous operation, we have designed the no-manned machine distant control model.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
The specific embodiment
As shown in Figure 1, free style excavator of the present invention comprises first hydraulic motor 1, second hydraulic motor 9; Wherein, the big arm of first hydraulic motor 1 and excavator 15 is connected through bolt, thereby and drive 4 rotations of first main shaft through the front end that first meshing gear 2 connects first main shaft 4, first hydraulic motor 1 is connected through spline with first meshing gear 2; First sleeve 3 through the first load bearing 6 be installed on first main shaft 4 outside and both to heart biserial, making the sleeve 3 of winning can serve as that axle rotates with first main shaft 4, the rear end of first sleeve 3 and center contiguous block spare 7 are hinged; First sleeve, 3 front ends are hinged with first hydraulic cylinder 5, and the other end of this first hydraulic cylinder 5 and center contiguous block spare 7 are hinged.
Second hydraulic motor 9 and center contiguous block spare 7 are connected through bolt, thereby and drive 12 rotations of second main shaft through the front end that second meshing gear 10 connects second main shaft 12, second hydraulic motor 9 and meshing gear 10 are connected through spline; Second sleeve 11 through the second load bearing 13 be installed on second main shaft 12 outside and both to heart biserial, make that second sleeve 11 can serve as that axle rotates with second main shaft 12, the rear end of second sleeve 11 and impact head 8 are hinged; The front end of second sleeve 11 is hinged with second hydraulic cylinder 14, and the other end of this second hydraulic cylinder 14 and impact head 8 are hinged.
