The invention relates to a supporting leg structure and a crane car, the supporting leg structure is used for being detachably connected to a frame of the crane car, the supporting leg structure comprises a plurality of supporting leg sections and telescopic pieces, the supporting leg sections are constructed to be detachably connected end to end, any one of the supporting leg sections is provided with the telescopic piece, and the telescopic pieces are arranged on the supporting leg sections. The telescopic part is arranged to be capable of extending in the direction close to the ground or shortening in the direction away from the ground, the supporting leg structure has an assembling state, in the assembling state, the supporting leg sections are connected end to end, and the supporting leg section closest to the crane car is detachably connected with a supporting leg connecting part on a frame of the crane car; the supporting leg section farthest from the crane car is provided with a telescopic piece. When the crane car carries out hoisting operation, the supporting leg structure is assembled on the crane car, the stability of the crane car is improved, after the crane car completes the hoisting operation, the supporting leg structure is detached from the car frame, and the width of the crane car cannot be increased in the traveling process of the crane car.

    本公开涉及一种支腿结构以及起重车,该支腿结构用于可拆卸地连接于起重车的车架,支腿结构包括多个支腿节和伸缩件,多个支腿节构造为能够首尾可拆卸地连接,多个支腿节中的任一支腿节上设置有伸缩件,伸缩件设置为能够朝向靠近地面的方向伸长或朝向远离地面的方向缩短,支腿结构具有组装状态,在组装状态,多个支腿节首尾连接,且最靠近起重车的支腿节用于与起重车的车架上的支腿连接部可拆卸地连接,最远离起重车的支腿节为设置有伸缩件的支腿节。当起重车进行起重作业时,将支腿结构组装在起重车上,提高起重车的稳定性,起重车完成起重作业后,将支腿结构从车架上拆卸下来,在起重车行驶过程中,不会增加起重车的宽度。
