The utility model discloses a segmental container clamping device, and aims to provide a segmental container clamping device, which can be used for controlling an initial state height and ensuring that a transportation state does not surpass limitation. The segmental container clamping device comprises two groups of clamping units with the same structure, wherein each group of clamping unit comprises an upright post, an upper clamping arm, a lower clamping arm, a swinging hydraulic cylinder, a rotating lock and a rotating lock driving mechanism; the upper clamping arm and the lower clamping arm are provided with a plurality of groups of corresponding positioning holes respectively; the upper clamping arm is connected with a piston rod of the swinging hydraulic cylinder arranged on the upright post; the upper end of the upper clamping arm is hinged with the upright post; the lower end of the upper clamping arm is connected with the upper end of the lower clamping arm through a pin; and the rotating lock is arranged at the lower end of the lower clamping pin, and is connected with the rotating lock driving mechanism. The clamping arm in the clamping device is formed by connecting the upper clamping arm and the lower clamping arm through the pin, so that the initial state height of the equipment can be controlled by adjusting the relative positions of the upper clamping arm and the lower clamping arm in a transportation state, and an ultralimit-free transportation state is ensured.
