Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.The description of this part is only exemplary
With it is explanatory, and the present invention multitude of different ways that can be defined by the claims and cover is implemented, should not be to the guarantor of the present invention
Shield scope has any restriction effect.
Referring to Fig. 1, in crawler body normal work, the connection of middle frame 3 needs the main machine structure carried.Right-hand track chiain beam 1
It is fixedly linked respectively by multiple bearing pins 4 and middle frame 3 with left track beam 2, forms a track bottom that is complete, can working
Disk.Along two symmetrical center lines of middle frame 3, four supporting legs 6 are respectively symmetrically installed, each supporting leg 6 passes through vertical rotating shaft 5
It is connected with middle frame 3.Supporting leg 6 can swing certain angle in the horizontal direction around vertical rotating shaft 5.Under this working condition, often
Individual supporting leg 6 is rocked to the position being close to middle frame 3, and fixed.A support oil cylinder 8 is fitted with each supporting leg 6, is propped up
