The invention discloses a GIS spider crane with variable supporting legs, and relates to the field of cranes, the GIS spider crane comprises a main vehicle body and a suspension arm, the outer side wall of the main vehicle body is provided with a plurality of rotating seats, one end of each rotating seat is connected with a supporting arm mechanism, and the supporting arm mechanism comprises a first supporting arm and a second supporting arm; the first supporting arm and the second supporting arm are rotationally connected through a rotating base, and the second supporting arm comprises a positioning base and a positioning supporting arm. The supporting arm mechanism is unfolded to support the main vehicle body, the second supporting arm is composed of the two positioning supporting arms, the positioning supporting arms can be unfolded, single-arm supporting in the prior art is converted into multi-arm multi-point supporting, a stable triangular supporting shape is formed, and when the second supporting arm is not unfolded, the positioning supporting arms can be unfolded to support the main vehicle body. The base plate on the base can increase the contact area of the base and the ground, the contact stability of the supporting arm mechanism and the ground is further improved, and the supporting arm mechanism can be better supported on the ground with different hardness.

    本发明公开了一种可变支腿的GIS蜘蛛吊机,涉及吊机领域,包括主车体与吊臂,所述主车体外侧壁安装有多个转动座,所述转动座的一端连接有支撑臂机构,所述支撑臂机构包括第一支撑臂与第二支撑臂,所述第一支撑臂与第二支撑臂之间通过旋转座转动连接,所述第二支撑臂包括定位座与定位支臂。本发明通过将支撑臂机构展开对主车体进行支撑,并且第二支撑臂由两个定位支臂构成,定位支臂可以展开,将原本现有技术中的单臂支撑转换为多臂多点支撑,形成一个稳定的三角支撑形状,并且第二支撑臂未展开时,底座上的底板还可以增大底座与地面的接触面积,进一步增加支撑臂机构与地面的接触稳定性,使其能更好的在软硬不一的地面进行支撑。
