The invention relates to a supporting leg turnover device of a truck with a crane. The supporting leg turnover device of the truck with the crane comprises a supporting leg cross beam and a supportingleg; the supporting leg is rotatably connected to the shaft end located on the end face of the supporting leg cross beam; a turnover oil cylinder is arranged on the supporting leg; a piston rod of the turnover oil cylinder is connected with the supporting leg cross beam through a rigid rope; the supporting leg is driven to do turnover motion through movement of the piston rod; a locking handle isarranged on the supporting leg; two locking holes matched with the locking handles are respectively formed in the end face of the supporting leg cross beam; and the locking handle is respectively connected with the two locking holes, so that the supporting legs are locked in a supporting position and a closing position. Compared with the prior art, the supporting leg turnover device of the truckwith the crane has the advantages the space below the supporting leg cross beam can be released through overturning of the supporting leg, and the running space of a vehicle is enlarged. Moreover, theturnover structure moves along with the supporting leg, so that no extra space is occupied, and supporting is more stable.

    本发明涉及一种随车吊机支撑腿翻转装置,包括支撑腿横梁和支腿,支腿可旋转地连接在位于支撑腿横梁端面的轴端上,且支腿上设有翻转油缸,翻转油缸的活塞杆通过刚性绳与支撑腿横梁连接,并通过活塞杆的运动带动支腿做翻转运动;支腿上设有锁紧把手,支撑腿横梁的端面设有分别与锁紧把手相匹配的两个锁紧孔,锁紧把手通过与两个锁紧孔分别连接,实现支腿在支撑和收拢位置的锁定。与现有技术相比,本发明能够通过支腿的翻转释放支撑腿横梁下方的空间,提高车辆的行驶空间。而且翻转结构随支腿运动,不会占用额外的空间,支撑也更加稳定。
