Then, dipper hydraulic device 221 and the cooperation driving bucket 1 of bucket hydraulic device 11 carry out digging operation, realize and dig
Function is dug, since the walking type excavator of the present invention is not provided with gyroscopic drive system, after bucket 1 excavates the cubic metre of earth and stone, by dynamic
Arm steering hydraulic device 212 drives sliding seat 35 to swing in the horizontal plane, to drive connection arm assembly 2 in the horizontal plane
It swings, to which the cubic metre of earth and stone of excavation to be placed on to the both sides of digging operation position.
Then, when walking type excavator needs advance operation, as shown in figure 3, by swing arm 21, dipper 22, connecting rod 12 with
And the mutual cooperation effect of bucket 1, so that the arc part of bucket 1 is contacted ground, to make bucket 1 form whole one of excavator
A supporting point, dipper hydraulic device 221 push the first end of dipper 22 so that grip supporting leg 33 leaves ground, and excavator is whole
It is the link mechanism of supporting point that body, which forms one with traveling wheel 31 and bucket 1, at this point, dipper hydraulic device 221 pushes dipper 22
First end, dipper 22 with bucket 1 be rotation center rotate and moved forward under the action of traveling wheel 31 with motor vehicles bodies 3,
The walking type excavator of the present invention makes the driving force that excavator integrally moves forward without providing.In addition, such as needing car body 3 backward
Mobile, dipper hydraulic device 221 pulls the first end of dipper 22 can be realized after shrinking.
Finally, bucket hydraulic device 11 is retracted, and bucket 1 is lifted up, and grip supporting leg 33 moves down, and grip supporting leg 33
Second end support on the ground, excavator is whole can be fixedly supported on the ground again by grip supporting leg 33 and traveling wheel,
To continue digging operation.
It is schematic diagram when walking type excavator rotates referring to Fig. 5, Fig. 5.The transhipment side of the walking type excavator of the present invention
Method includes the following steps.
First, the first fixing piece sequentially passes through the mounting hole on fixed part 341 and fixed part 37 and is fixed on supporting rod 34
On car body 3, and supporting rod 34 is made to extend in vertical direction, the support of walking auxiliary wheel 32 is on the ground.
Then, grip supporting leg hydraulic device 331 drives grip supporting leg 33 to rotate, and the second end of grip supporting leg 33 is made to leave ground
Face.
Finally, walking type excavator moves forward and enters transport vehicle.
In addition, car body can also include the rotary table and revolving platform that are hinged, the second end of connection arm assembly with
Revolving platform is hinged, and traveling wheel, walking auxiliary wheel and grip supporting leg are mounted on rotary table, big by the way that revolving platform is arranged
The big job area for increasing walking type excavator.In addition, when walking type excavator is transported through, it can also be by grip supporting leg and row
It walks auxiliary wheel to pack up, to which directly haul excavator is whole.Said program can also achieve the object of the present invention.
Therefore by the way that grip supporting leg and setting is arranged by supporting rod and the hinged walking auxiliary wheel of car body, make
Obtaining walking type excavator can support progress operation, in transhipment, can pass through auxiliary of walking in operation by grip supporting leg
Wheel is moved.The walking type excavator of the present invention, simple in structure, economic performance is higher, and adapts to complicated landform, especially
It adapts in operation in narrow space and operations specific, such as ditching canal.In addition walking type excavator transhipment is convenient, without spy
Fixed loading vehicles, can both be got on the bus transport with complete machine, trailer can also be used to haul.In addition, walking type excavator is not walked
Drive system and rotary system, power consumption is each hydraulic device, therefore required power is smaller, energy conservation and environmental protection.
