Several pressure loading hydraulic rods 30 are uniformly fixedly installed on the lower surface of the mounting plate 29. During operation, the position-adjusting electric lead screw 39 is energized, causing it to rotate. This rotates the pressure-applying nut block 7, which in turn moves the lifting groove frame 3 to the corresponding position. Once in the correct position, the lifting electric lead screw 43 is energized, causing it to rotate.

During this downward movement, the position-adjusting electric telescopic plate 27 is energized, causing it to extend to a suitable length. After the pressure-loading hydraulic rod 30 moves downwards and contacts the T-beam 21, hydraulic oil is introduced into it, causing it to extend and press against the T-beam 21, thus applying pressure to the T-beam 21. The position and direction of the pressure are adjusted accordingly.

The active bevel gear 70 meshes with the driven bevel gear 71, thereby driving the driven bevel gear shaft 38 to rotate, which in turn drives the mounting plate 29 to rotate, thereby driving the pressure loading hydraulic rod 30 to rotate. After rotating to a certain angle, loading can be achieved in different angle directions. The position adjustment electric telescopic plate 27 can also be adjusted to achieve different pressure loading on the flanges and webs of the T-beam 21.

When the height of the T-beam 21 needs to be adjusted, the support height adjustment is provided. When the electric lead screw 52 is energized, it rotates, thereby pushing the grooved support frame 12 upward, which in turn moves the T-beam 21 upward, facilitating the simulation of a simply supported beam under load on the T-beam 21. When the support adjustment electric lead screw 51 is energized, it rotates, causing the support adjustment threaded plate 50 to move, which in turn moves the support height adjustment electric lead screw 52, ​​which in turn moves the grooved support frame 12. This allows for adjustment of the distance between the grooved support frames 12. During distance adjustment, the clamping of the T-beam 21 is released.
