The utility model discloses a hydraulic quick-change trolley device for clamp switching, which comprises a movable frame and jacking mechanisms symmetrically arranged on the movable frame, the jacking mechanism comprises hydraulic cylinders fixedly arranged on the movable frame, a jacking plate connected with the output ends of the hydraulic cylinders and a tool positioning unit arranged on the jacking plate, and a hydraulic pump used for driving the two hydraulic cylinders at the same time is further arranged on the movable frame. The four positioning units and the stable and balanced manual hydraulic cylinder are used for outputting force, so that the dismounting stress is balanced and uniform, the influence on the size of the tool is very small, and the stability and the reliability of the device are high; the working space is small, the tool can be replaced in the narrow working space, and the problem that a traditional forklift cannot enter for operation is solved. 本实用新型公开了一种用于夹具切换的液压快换小车装置，包括移动框架以及对称设置在
