[0029] Working principle: When in use, place the prepared friction plate on the ground and push the device so that the friction plate is located in the middle of the U-shaped base frame 1, and the short side of the friction plate is perpendicular to the ground. Control the first hydraulic cylinder 10 and the second hydraulic cylinder 15 to retract, so that the rotating bracket 5 gradually descends, while the lifting frame 6 remains horizontal until the lifting frame 6 is close to the ground, start the third hydraulic cylinder 18 on both sides, so that the two U-shaped clamping plates 21 are close to each other, and the friction plates are fixedly clamped near both ends by the anti-slip pads 22.

When the friction plate is raised, the second hydraulic cylinder 15 is activated to control the extension of the lifting frame 6, causing the lifting frame 6 to gradually return to a vertical position, approaching the universal testing machine and being installed on it. The bottom of the testing machine first fixes the bottom of the friction plate, and then the device moves away. The testing machine then fixes the bottom of the friction plate to realize the friction plate testing. By changing the height of the limit rod 9, the rotation angle of the U-shaped rotating frame 7 is adjusted when the first hydraulic cylinder 10 is retracted. When the equipment is transferred, the limit rod 9 can be adjusted to the lowest position. When the lifting frame 6 is at the lowest position, the braked universal wheels 301 remain on the ground, without affecting the movement of the device.
