Multidirectional loading device used for coil support test in Tokamak

The invention discloses a multidirectional loading device used for a coil support test in a Tokamak. The multidirectional loading device includes a rectangular steel support frame and a profile-steel clamping frame. The rectangular steel support frame is connected with a base of the coil support through bolts. One end of the coil support is connected and clamped tightly with the profile steel clamping frame through bolts. The profile-steel clamping frame is connected with steel wire ropes through pins. The steel wire ropes are connected with thrust plates through pins. Front-rear-direction loading jacks of the support are arranged at the front side or rear side of the rectangular steel support frame. Left-right-direction loading jacks of the support are arranged at the left side or right side and the front side or rear side of the rectangular steel support frame. Up-down-direction loading jacks of the support are arranged on or beneath the rectangular support frame. The jacks at the three directions apply needed tensile to the profile-steel clamping frame through the steel wire ropes, the pins and the thrust plates so that the coil support bears a single-direction force load. The multidirectional loading device used for the coil support test in the Tokamak is simple and compact in structure, convenient to use and capable of realizing applying of forces and torques in three directions and performing engineering testing on the coil support.
