[0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. A bridge is generally composed of an upper structure, a lower structure, supports and ancillary structures. The upper structure, also known as the span structure, is the main structure for crossing obstacles; the lower structure includes abutments, piers and foundations; the supports are force transmission devices installed at the supporting locations between the span structure and the piers or abutments; the ancillary structures refer to the bridgehead cladding, conical slope protection, bank protection, diversion projects, etc.

[0003] In bridge construction, bridge transport vehicles are indispensable tools. When existing bridge transport vehicles are transporting bridges across uneven roads, or when the vehicles are turning, stress concentration occurs at the contact point between the bridge and the bridge transport vehicle, which can cause local bumps, defects, or even deformation and scrapping of concrete beams. Existing bridge transport vehicles use ropes to fix the bridge to the bridge transport vehicle, but during transportation, the center of gravity of the bridge is relatively high, and the problem is that it is easy to become unstable and poses a safety hazard.

When the internal combustion fixed platform transporter passes through an uneven road surface, the bridge It will form a certain angle with the internal combustion fixed platform transport vehicle, which will cause local collision of the bridge, or even deformation and scrapping, and the pitching plate 5 will make corresponding swings on the transport vehicle 1 to ensure that the transport vehicle 1 is in full contact with the bridge to avoid angle folding and damage to the bridge; a rotatable bearing plate 7 is arranged above the pitching plate 2, and when the internal combustion fixed platform transport vehicle turns, the bearing plate 7 makes corresponding rotation to avoid the bridge from folding at an angle when the internal combustion fixed platform transport vehicle turns, causing damage to the bridge; a base 8 is arranged on the bearing plate 7, and the left side of the base 8 Support components 9 are symmetrically arranged on the right and left sides, and the support components 9 include support plates 10. The support plates 10 are connected to the base 8 by an inclined plate 11. When the bridge is placed on the base, the inclined plate can limit the bottom end of the bridge. The support plates 10 are provided with side plates 12. A through hole 13 is arranged in the middle of the side plates 12. The through hole 13 is a rope fixing hole. When the bridge is placed on the base 8, the rope is passed through the top of the bridge, and the two ends of the rope are fixed to the through hole 13 accordingly, so that the bridge is fixed to the internal combustion fixed platform transporter; the support plates A screw rod 14 is hinged on the upper surface of 10, and a support rod 15 is spirally connected above the screw rod 14. When fixing the bridge, the length of the support rod is fine-tuned by rotating the support rod so that the support rod can better fit the bridge and better fix the bridge. The support rod 15 is located on the right side of the through hole 13, and a detachable support member 16 is provided at the upper end of the support rod 15; the support rod 15 is used to support and fix the two ends of the bridge. Since the support rod 15 is symmetrically arranged with respect to the left and right centers, the support rod 15 is placed parallel and reversely on the support plate 10 when not in use.

[0025] Please refer to Figures 3 to 6In one embodiment of the present invention, a threaded shaft 17 is provided in the middle of the lower surface of the bearing plate 7, and a shaft hole 18 is opened in the middle of the pitch plate 2.
