The invention provides a locking device, a concave underframe and a piggyback transport vehicle with the concave underframe. A locking device is arranged on the piggyback transport vehicle and used for locking a container located on a concave underframe of the piggyback transport vehicle. The locking device comprises a locking rod used for being matched with a locking part on the container to lockthe container, the locking rod is provided with a locking position and an unlocking position, and the locking rod is rotatably arranged so as to be switched between the locking position and the unlocking position; a mounting base is fixedly connected with the concave underframe, a locking structure is arranged on the mounting base, and the locking structure is movably arranged relative to the mounting base, so that when the locking rod is located at the unlocking position, the locking structure can be matched with the locking rod in a clamped mode so as to limit the locking rod at the unlocking position. By the adoption of the technical scheme, the problem that in the prior art, the container locking structure on the piggyback transport vehicle is prone to interfering with a highway truckcan be solved.

    本发明提供了一种锁闭装置、凹底架及具有其的驮背运输车。锁闭装置设置在驮背运输车上,用于锁闭位于驮背运输车的凹底架上的集装箱;锁闭装置包括:锁定杆,用于与集装箱上的锁定部配合锁定集装箱,锁定杆具有锁定位置和解锁位置,锁定杆可转动地设置,以在锁定位置和解锁位置之间切换;安装座,与凹底架固定连接,安装座上设有锁定结构,锁定结构相对于安装座可移动地设置,以使锁定杆位于解锁位置时,锁定结构能够与锁定杆卡接配合,以将锁定杆限制在解锁位置。应用本发明的技术方案,可以解决现有技术中的驮背运输车上的集装箱锁闭结构容易与公路货车发生干涉的问题。
