The utility model discloses a live working robot and remove chassis device thereof, the removal chassis device of live working robot includes: the directive wheel of chassis front end is located to the chassis, locates the drive wheel of chassis rear end, and the homoenergetic is enough along the flexible preceding levelling mechanism and back levelling mechanism of vertical direction, wherein, preceding levelling mechanism is fixed in the front end of chassis, and the rear end of chassis is located to back levelling mechanism. The utility model discloses a removal chassis device of live working robot has then realized directly carrying out the regulation of vertical orientation through preceding levelling mechanism and back levelling mechanism, and the horizontal direction of going advanced than prior art is adjusted and is carried out vertical orientation again and adjust and compare, can effectively reduce the area after the leveling of the whole chassis device of removal, area when then having reduced live working robot operation, simultaneously, realize the leveling through the regulation of only carrying out vertical direction, reduced the regulation direction to reduce the leveling time, improved leveling efficiency.
