The invention discloses an automobile crane. The automobile crane comprises a crane body assembly, a support arm assembly and a lifting assembly, wherein a bottom plate is located at the bottom of a to-be-lifted crane body, two first grooves and two first enclosed pieces are symmetrically formed and arranged along the transverse center line of the bottom plate, two second grooves, two second enclosed pieces and two first steel wire ropes are symmetrically formed and arranged along the longitudinal center line of the bottom plate, a first chute communicates with the first grooves, a second chute communicates with the second grooves, the two first steel wire ropes penetrate through the bottom plate and are fixedly connected with the support arm assembly, a first fixed piece is connected to the interiors of the first grooves in a sliding mode and is abutted with the to-be-lifted crane body, a first sliding piece is connected to the interiors of the first chute and a first through groove in the sliding mode, a second fixed piece is connected to the interiors of the second grooves in the sliding mode, a second sliding piece is connected to the interiors of the second chute and a secondthrough groove in the sliding mode, and two movable pieces are rotatably connected and are connected with the second fixed piece and an extension piece in the sliding mode. The to-be-lifted crane bodyis located in the geometric center of the bottom plate and is fixedly enclosed so as to prevent from falling and being damaged.

    本发明公开了一种汽车起重机械,包括车体组件、支臂组件和吊装组件,底板位于待吊装车体底部,两个第一凹槽和两个第一围合件均沿底板横向中心线对称设置,两个第二凹槽、两个第二围合件和两个第一钢丝绳均沿底板纵向中心线对称设置,第一滑槽与第一凹槽连通,第二滑槽与第二凹槽连通,两个第一钢丝绳贯穿底板与支臂组件固定连接,第一固定件滑动连接于第一凹槽内,且抵持待吊装车体,第一滑动件滑动连接于第一滑槽和第一通槽内,第二固定件滑动连接于第二凹槽内,第二滑动件滑动连接于第二滑槽和第二通槽内,两个移动件转动连接,且与第二固定件和延伸件滑动连接。实现待吊装车体位于底板几何中心,且进行围合固定,避免脱落损坏。
