[0033] The rotation of gear 601 drives rack 602 to move up and down, rack 602 drives sliding plate 604 to move up and down, sliding plate 604 drives sliding block 605 to move up and down, sliding block 605 drives first sleeve 606 and second sleeve 608 to move up and down. Since the upper end of the beam body is at an inclined angle, when the rubber plate 615 contacts the side wall of the beam body, the sliding block 605, the first sleeve 606 and the second sleeve 608 continue to move up. At this time, the contact force between the rubber plate 615 and the beam body increases, driving the semicircular sleeve 614 to slide on the semicircular shaft 613. At this time, the rubber plate 615 will eventually maintain a contact and parallel state with the inclined beam body, and the damping spring 610 can generate a shock-absorbing force on it.

[0034] Working principle:

[0035] S1. Place the beam on the transport vehicle body 101 with the aid of a sling, start the jack 201 to drive the adjustment plate 202 to slide on the sliding guide rail 204, and the front and rear position of the beam can be limited by the cooperation of the sliding guide rail 204 and the limit plate 103, so as to adapt to beams of different lengths;

[0036] S2, start the driving motor 301 to drive the bidirectional screw rod 302 to rotate, and the bidirectional screw rod 302 rotates and cooperates with the adjustment block 304 to enable the adjustment block 304 to perform relative or opposite movement on the second mounting frame 303, so as to adapt to beams of different widths;

[0037] S3, the rotation of the bidirectional screw rod 302 drives the first bevel gear 401 to rotate, the rotation of the first bevel gear 401 drives the second bevel gear 402 to rotate, the rotation of the second bevel gear 402 drives the rotating shaft 403 to rotate, the rotation of the rotating shaft 403 drives the small gear 502 and the gear 601 to rotate, the rotation of the small gear 502 drives the large gear 501 to rotate, the rotation of the large gear 501 drives the bearing plate 504 to rotate, the bearing plate 504 drives the adjusting arm 507 to pull the connecting arm 508 to rotate, the connecting arm 508 drives the receiving frame 509 and the rubber ball 510 to move to a suitable position, because the rubber ball 510 is made of elastic material, there will be no problem of excessive abutment force and damage to the components and the beam body during the movement and adjustment, and it has a shock absorbing and supporting effect on it, and there is friction between the rubber ball 510 and the beam body, which can avoid the phenomenon of slippage during the transportation of the beam body;

[0038] S4, the rotation of gear 601 drives rack 602 to move up and down, rack 602 drives sliding plate 604 to move up and down, sliding plate 604 drives sliding block 605 to move up and down, sliding block 605 drives first sleeve 606 and second sleeve 608 to move up and down. Since the upper end of the beam body is at an inclined angle, when the rubber plate 615 contacts the side wall of the beam body, the sliding block 605, the first sleeve 606 and the second sleeve 608 continue to move up. At this time, the contact force between the rubber plate 615 and the beam body increases, driving the semicircular sleeve 614 to slide on the semicircular shaft 613. At this time, the rubber plate 615 will eventually maintain a contact and parallel state with the inclined beam body, and the damping spring 610 can generate a shock-absorbing force on it.
