Parts title and serial number in figure:
Walker 1, propelling cylinder 2, travelling arm 3, elevating ram 4, leading arm 5, corner 6.
Specific embodiment
Illustrate specific embodiment with reference to the accompanying drawing.
In the present invention
As shown in figure 3, host in the present embodiment be it is rotary, there is the walker 1 positioned at lower part and revolution installation
Upper body 7 on walker.As shown in Figure 1, traveling auxiliary device is installed at the rear portion of walker 1, traveling auxiliary
Device includes two sets of propulsion devices arranged side by side, as shown in Fig. 2, every set propulsion device includes: leading arm 5, travelling arm 3, promotes oil
Cylinder 2, elevating ram 4.
Leading arm 5 is in square tube type, and one end is hinged end, and the other end is free end, and hinged end and walker 1 are hinged；It leads
It can be swung up and down to arm 4 around its hinged end.
Travelling arm 3 is arranged in leading arm 5, and travelling arm 3 is only capable of sliding along 5 length direction of leading arm, and travelling arm 3 is from guiding
5 free end of arm is stretched out, and the extension end of travelling arm 3 has the corner 6 extended downwardly.
Propelling cylinder 2 is arranged in leading arm 5, and both ends are connect with leading arm 5 and travelling arm 3 respectively, propelling cylinder 2
It is flexible that travelling arm 3 is pushed to be oppositely oriented the sliding of arm 5.
Elevating ram 4 is connected between walker 1 and leading arm 5, and the flexible promotion leading arm of elevating ram 4 is hinged around it
End is swung up and down.
Forestry machinery in the present embodiment makes two sets of propulsions when the precipitous place of the gradient is advanced, such as when climbing first
Elevating ram 4 in device all stretches out, and leading arm and travelling arm is pushed to insert to lower swing, and by the corner on travelling arm extension end
Enter in soil, so that complete machine be fixed.
When operating complete machine running gear makes complete machine climb, the propelling cylinder 2 in every set propulsion device, which synchronizes, to be stretched out, and makes two
The travelling arm covered in propulsion device stretches out leading arm, pushes complete machine climbing to play, and play during climbing to complete machine
Supporting role avoids complete machine from tumbling backward.
When the elongation of propelling cylinder 2 to the end, then the lifting in wherein a set of propulsion device (calling A set propulsion device in the following text) is operated
Oil cylinder 4 makes its retraction, so that the corner for covering travelling arm extension end in propulsion device A be extracted from soil, the A that then bounces back is promoted
Propelling cylinder 2 in device after the recycling of propelling cylinder drives travelling arm 3 to be fully retracted into leading arm 5, then operates A propulsion
Propelling cylinder 4 in device makes its stretching, will be in the corner insertion soil on the travelling arm 3 in A propulsion device.Then again with phase
With method operate another set of propulsion device (calling B set propulsion device in the following text), make the leading arm in B propulsion device be lifted and corner from
It is extracted in soil, travelling arm retraction, leading arm decline and corner is inserted into soil.Corner to two sets of propulsion devices is all inserted into
After into soil, the propelling cylinder in two sets of propulsion devices, which synchronizes, to be stretched out, and forestry machinery is pushed to climb forward.
In the present embodiment, two sets of propulsion devices also can work alternately promote complete machine climb forward namely A set promote dress
The corner set is inserted in soil, propelling cylinder stretches out while pushing complete machine climbing, and B covers the elevating ram in propulsion device
Propelling cylinder of the retraction by the corner in B propulsion device after being extracted in soil in retraction B propulsion device；When A covers propulsion device
Propelling cylinder when extending out to the end, B is covered into the corner in propulsion device and is inserted into soil the corner of A set propulsion device simultaneously
It is extracted from soil, then stretches out the propelling cylinder in B set propulsion device and push in complete machine climbing while A set propulsion device
Propelling cylinder retraction, to push next time complete machine climbing to prepare.
