The invention provides a high thrust vector vertical type test device structure, belongs to the technical field of sensing and measurement and control, and solves the technical problems that the present solid rocket engine test device has low inherent frequency and small test range so that the engine thrust vector test precision can be enhanced by changing the conventional horizontal structure into the vertical structure. The device comprises an adapter frame, lateral loading devices, an eight-position calibration board, a dynamometer, a key, a connecting cylinder, a hydraulic power system, anupper plate, reinforcing ribs a, reinforcing ribs b, a bearing cylinder and a lower plate. The device is large in measurement range, great in structural processability, high in precision, great in dynamic characteristics and easy to install and debug so that the space force and the moment can be simultaneously tested and the engine thrust vector characteristics can be more comprehensively and accurately tested.
