The invention belongs to the technical field of semitrailers, and discloses a lightweight semitrailer frame. Comprising a frame body, a top frame is fixedly connected to the top end of one side of the frame body, first door plates are rotatably connected to the top ends of the two sides of the frame body through rotating shafts, a second door plate is rotatably connected to the side, away from the top frame, of the frame body through rotating shafts, and a fixing sleeve is fixedly connected to the bottom of the frame body. When the position of a cylindrical cargo needs to be fixed, a rotating motor is started to drive a rotating shaft and a first gear to rotate, and the first gear drives two groups of first racks, second racks, second gears, long rods, connecting blocks and fixing plates to operate at the same time, so that the two groups of fixing plates can overturn towards the center at the same time; the two sides of the cylindrical goods can be fixed by turning the two sets of fixing plates towards the center, and the problem that the cylindrical goods are prone to falling off when conveyed by the frame of the semitrailer is solved.

    本发明属于半挂车技术领域,本发明公开了一种轻量化的半挂车车架;包括车架本体,所述车架本体一侧的顶端固接有顶框,所述车架本体两侧的顶端通过转轴转动连接有第一门板,所述车架本体远离顶框的一侧通过转轴转动连接有第二门板,所述车架本体的底部固接有固定套,本装置通过设置固定组件,可在需要对圆筒状货物的位置进行固定时,启动旋转电机带动转轴和第一齿轮转动,并通过第一齿轮带动两组第一齿条、第二齿条、第二齿轮、长杆、连接块和固定板同时运行,从而可使两组固定板同时向中心处翻转,可通过两组固定板向中心处翻转来将圆筒状的货物两侧进行固定,解决了半挂车的车架运送圆筒状货物时容易发生脱落的问题。
