The moving mechanism is fixedly installed on the outside of the rotary bending fatigue testing machine body. The moving mechanism includes a U-shaped shell fixedly installed on the outer wall of the rotary bending fatigue testing machine body. A U-shaped frame is slidably installed inside the U-shaped shell. Four matrix-distributed support columns are fixedly connected to the bottom of the U-shaped frame. Rollers are rotatably installed at the lower end of the support columns. A screw is rotatably installed on one side inside the U-shaped shell. The U-shaped frame is sleeved on the screw and threadedly connected to the screw.

[0007] In a preferred embodiment, there are four rollers, which are distributed in pairs on both sides of the body of the rotary bending fatigue testing machine.

[0008] In a preferred embodiment, a motor is fixedly mounted on the top of the U-shaped housing, and the output end of the motor is fixedly connected to the upper end of the screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This horizontal high-speed rotary bending fatigue testing device, through the setting of a moving mechanism, can be installed on the outside of the rotary bending fatigue testing machine body without affecting the function of the rotary bending fatigue testing machine body. When it is necessary to move the rotary bending fatigue testing machine body, it is only necessary to start the motor. The motor drives the screw to rotate, the screw drives the U-shaped frame to slide vertically along the guide rod inside the U-shaped shell, the U-shaped frame drives the support column to descend, and the support column drives the roller to contact the ground. The roller can then be used to push the rotary bending fatigue testing machine body to move on the ground, eliminating the need for manual handling and saving time and effort.
