The invention discloses an anti-tilting girder of a semi-trailer dump truck. The girder comprises two longitudinal beams arranged in parallel and two cross beams arranged between the two longitudinalbeams; the two cross beams and the two longitudinal beams form a rectangular frame; and the girder is characterized in that turnover supporting legs are arranged on the two longitudinal beams, each turnover supporting leg comprises a horizontal turnover supporting rod and a vertical turnover supporting rod, one end of each horizontal turnover supporting rod is rotatably connected with the corresponding longitudinal beam, and each horizontal turnover supporting rod can rotate on the corresponding longitudinal beam in the horizontal direction through a connecting point. The technical scheme is adopted, a plurality of turnover supporting legs can be arranged and are each composed of the horizontal turnover supporting rod and the vertical turnover supporting rod, connecting rods are connectedwith the longitudinal beams in a rotary connection manner, after overturning, the horizontal overturning supporting rod serves as a transverse extension of the longitudinal beam, and the vertical overturning supporting rod serves as a supporting point of the longitudinal beam in contact with the ground after extending, so that the transverse area of the girder can be effectively extended, the gravity center height of the overturned cargo tank is reduced, the stability of the truck is improved, and the rollover risk is reduced.

    本发明公开了一种防倾斜半挂自卸车大梁,包括两根平行设置的纵梁和两根纵梁之间的横梁,两根横梁与两个纵梁构成矩形框架,其特征在于:两个纵梁上均设置有翻转支撑支脚,翻转支撑支脚包括水平翻转支撑杆和垂直翻转支撑杆,水平翻转支撑杆一端与纵梁转动连接,且能够以连接点在纵梁上作水平方向转动。本技术方案,翻转支撑支脚可以设置多个,其由水平翻转支撑杆和垂直翻转支撑杆组成,且通过转动连接方式与纵梁连接,在翻转之后,水平翻转支撑杆将作为纵梁的横向延伸,垂直翻转支撑杆将作为纵梁延伸后与地面接触的支撑点,能够有效延伸大梁的横向面积,以降低货箱翻转后的重心高度,提高其稳定性,降低发生侧翻的风险。
