Description
Technical field
The invention belongs to engineering and field of material technology, relate to a kind of engineering construction machinery, specifically a kind of free style excavator, this free style excavator can be applicable to boring and excavates.
Background technology
Excavator, also known as excavation machinery (excavating machinery), is excavate higher or lower than the material holding machine side with scraper bowl, and loads haulage vehicle or unload the earth moving plant to rickyard.Material mainly soil, coal, silt and the Soil and Rock after pre-pine that excavator excavates.From the development of engineering machinery in recent years, the development of excavator is relatively very fast, and excavator has become one of topmost engineering machinery in engineering construction.But under complex working condition, traditional Work machine due to the impact direction of its impact head can only downwards or forward, operation degree of freedom is less, thus when carrying out construction operation, flexibility is relatively poor, especially, when in the face of the operating mode such as narrow, severe, substantially cannot operate at first neighborhood accessibility, have significant limitation.Therefore, study a kind of impact head flexibility better, the excavator that impact direction flexibility ratio is large very has realistic meaning.
Summary of the invention
The defect existed for above-mentioned prior art or deficiency, the object of the invention is to, a kind of free style excavator is provided, this excavator is by increasing one degree of freedom respectively at big arm of digger, forearm, make impact head when carrying out construction operation, flexibility improves greatly, especially when in the face of the operating mode such as narrow, severe, 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 the first hydraulic motor, the second hydraulic motor; Wherein, the large arm of the first hydraulic motor and excavator is connected, and connects the front end of the first main shaft by the first meshing gear thus drive the first main shaft to rotate, and the first hydraulic motor and the first meshing gear pass through spline joint; It is outside and to heart biserial both 0 that first sleeve is installed on the first main shaft by the first load bearing, makes the first sleeve can with the first main shaft for axle rotates, and rear end and the center contiguous block part of the first sleeve are hinged; First barrel forward end is hinged with the first hydraulic cylinder, and the other end and the center contiguous block part of this first hydraulic cylinder are hinged.
Second hydraulic motor and center contiguous block part are connected, and connect the front end of the second main shaft by the second meshing gear thus drive the second main shaft to rotate, and the second hydraulic motor and meshing gear pass through spline joint; Second sleeve is installed on that the second main shaft is outside by the second load bearing and both are to heart biserial, makes the second sleeve can with the second main shaft for axle rotates, and rear end and the impact head of the second sleeve are hinged; The front end of the second sleeve is hinged with the second hydraulic cylinder, and the other end and the impact head of this second hydraulic cylinder are hinged;
Hydraulic cylinder hinged on first sleeve and the second sleeve, the first hydraulic motor, the second hydraulic motor are all connected to control room main frame.
The present invention also comprises following other technologies feature:
The large arm of described first hydraulic motor and excavator is connected by bolt.
Described second hydraulic motor and center contiguous block part are connected by bolt.
Advantage of the present invention is as follows: on the direction scope of the impact head of original excavator, adds two rotary freedoms, and these two rotary freedoms significantly add the working range of excavator, and by the design of sleeve,
The large forearm of free style excavator all adds two brand-new degree of freedom, makes it to have very high freedom, and opereating specification is more extensive, and can impact all directions centered by it, its flexible performance has met or exceeded the flexible performance of common mechanical arm; It can realize Multi-angle impact to same operand, to reach the object destroyed completely, impacts in the operating mode also can be difficult to impact at general excavator, inconvenience is freely advanced, rotating; Meanwhile, for adapting to more dangerous operation, we devise no-manned machine distant control model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Detailed description of the invention
As shown in Figure 1, free style excavator of the present invention, comprises the first hydraulic motor 1, second hydraulic motor 9; Wherein, the first hydraulic motor 1 is connected by bolt with the large arm 15 of excavator, and connects the front end of the first main shaft 4 by the first meshing gear 2 thus drive the first main shaft 4 to rotate, and the first hydraulic motor 1 and the first meshing gear 2 pass through spline joint; First sleeve 3 is installed on that the first main shaft 4 is outside by the first load bearing 6 and both are to heart biserial, makes the first sleeve 3 can with the first main shaft 4 for axle rotation, and rear end and the center contiguous block part 7 of the first sleeve 3 are hinged; First sleeve 3 front end is hinged with the first hydraulic cylinder 5, and the other end and the center contiguous block part 7 of this first hydraulic cylinder 5 are hinged.
Second hydraulic motor 9 is connected by bolt with center contiguous block part 7, and connects the front end of the second main shaft 12 by the second meshing gear 10 thus drive the second main shaft 12 to rotate, and the second hydraulic motor 9 passes through spline joint with meshing gear 10; Second sleeve 11 is installed on that the second main shaft 12 is outside by the second load bearing 13 and both are to heart biserial, makes the second sleeve 11 can with the second main shaft 12 for axle rotation, and rear end and the impact head 8 of the second sleeve 11 are hinged; The front end of the second sleeve 11 is hinged with the second hydraulic cylinder 14, and the other end and the impact head 8 of this second hydraulic cylinder 14 are hinged.
Hydraulic cylinder hinged on first sleeve 3 and the second sleeve 11, the first hydraulic motor 1, second hydraulic motor 9 are all connected to control room, control work by control room.
The impact head that impact head 8 adopts ordinary excavator to use, its inner workings is identical.
Operating principle of the present invention: the first hydraulic motor 1 drives the first main shaft 4 to rotate by the first meshing gear 2, first main shaft 4 rotates and drives first set cylinder 3 to rotate around the first main shaft 4, center contiguous block part 7 rotates under the drive of the first sleeve 3, and center contiguous block part 7 can move relative to the first sleeve 3 under the effect of the first hydraulic cylinder 5.Second hydraulic motor 9 drives the second main shaft 12 to rotate by the second meshing gear 10, second main shaft rotarily drives the second sleeve 11 and rotates with the second main shaft 12, impact head 8 rotates under the drive of the first sleeve 3, and impact head 8 moves relative to the second sleeve 11 under the effect of the second hydraulic cylinder 14.Thus realize increasing by two Space Rotating degree of freedom on the impact head 8 of ordinary excavator, make construction convenient and quick.
