The multiple cavities of corresponding connection, on the fuselage that the supporting leg is installed by supporting leg free bearing, and the inner end of supporting leg is arranged on cavity
Interior, the outer end of the supporting leg through mounting groove and is stretched out.
In order to which complete machine width minimizes when realizing supporting leg retraction, the mounting groove dislocation arrangement in the fuselage left and right sidewall.
The dislocation arrangement refers to that two relative supporting legs of left and right are not arranged on the same straight line, and so further subtracts for overall width
It is small to provide condition.
In order to improve the stability of walking, the outer end of the supporting leg of described fuselage the same side is arranged on same walking mechanism
On.
Preferably, the piling machinery is walking-type piling machinery.
Compared with prior art, the beneficial effects of the utility model are：This practicality can newly accomplish fuselage under housing
The length of one supporting leg, the length that two supporting legs need to be housed than prior art are much smaller（The width of short one leg）, meanwhile, this
Also the working width of complete machine is reduced while utility model can reduce fuselage width, material is saved, reduces manufacture
Cost.
