The invention provides a semitrailer and a semitrailer frame, and the semitrailer frame comprises an outer cross beam, an inner beam, a lifting lock head, a base and a lock pin assembly. The inner beam can stretch out and draw back in the extending direction of the outer cross beam, the lifting lock head moves to a certain set position along with the inner beam, and therefore the horizontal position of the lifting lock head in the width direction of the semitrailer frame can be adjusted. Through cooperation of the base, the lock pin assembly, the outer cross beam and the inner beam, the position locking of the outer cross beam and the inner beam is achieved. Meanwhile, a pin in the lock pin assembly is blocked by the base, the base limits the axial movement of the pin, and the situation that the pin is disengaged is avoided. The semitrailer can be used for transporting containers or mechanical equipment with different widths, so that the practicability of the semitrailer is enhanced, the semitrailer is multipurpose, different types of semitrailers do not need to be selected for the containers or the mechanical equipment with different widths, the number and cost of purchased vehicles of vehicle using units are reduced, and contributions are made to energy conservation and environmental protection.

    本发明提供了一种半挂车及其车架,其中,车架包括外横梁、内梁、升降锁头、基座、锁销组件。内梁能够在外横梁的延伸方向上实现伸缩,升降锁头随该内梁一起移动到某一设定位置,从而实现了在半挂车车架的宽度方向上升降锁头的水平位置可调。通过基座、锁销组件、外横梁和内梁的配合,实现外横梁和内梁的位置锁定。同时,锁销组件中的销被基座加以阻隔,该基座限制了销的轴向移动,避免了出现脱销的情况。本发明中半挂车可用来运输不同宽度的集装箱或机械设备,从而增强了半挂车的实用性,实现了一车多用,无需再为不同宽度的集装箱或机械设备选配不同型号的半挂车降低用车单位的购车数量和成本,为节能环保作出了贡献。
