Spatial transportation piping static test displacement load realizing device

The invention belongs to the technical field of structure static test, and specifically relates to a spatial transportation piping static test displacement load realizing device. A gantry a and a gantry b are fixed to a bearing ground rail. The projection coordinates of the loading end face of a spatial piping in a loading plane are marked on the bearing ground rail, the gantry a and the gantry b. The fixed ends of an automatic actuator b, an automatic actuator c and an automatic actuator d are respectively fixed to the corresponding coordinate positions of the gantry a and the gantry b, and the degree of freedom of the three automatic actuators in all the directions other than the loading direction is limited. The spatial transportation piping static test displacement load realizing device of the invention is successfully applied to spatial transportation piping static test, the displacement load of test pieces is successfully simulated, the test pieces neither lose stability nor are damaged under the maximum load, and the structural strength meet the requirements. The test data is accurate and reliable, truly reflects the deformation of test pieces under stress, and is basically consistent with the theoretical calculation result. The test is a complete success.
