[0026] As shown in Figures 1-5 A bridge connecting member and a bridge, comprising a beam frame, comprising an upper cover plate 1 and a lower cover plate 2 assembled thereon for guiding and sliding the beam frame;

[0027] The fixed pad 4 is arranged at the middle part of the lower cover plate 2 and between the two beam frames, and the support frame 8 for abutting against the inner wall of the beam frame is symmetrically and slidingly arranged on the fixed pad 4.

[0028] The sliding frame 5 is slidingly arranged on the lower cover plate 2 and forms a sliding fit with the support frame 8.

[0029] The sliding frame 5 is pushed by the beam frame to be inserted into the fixed pad 4.

[0030] Specifically, the bottom of the upper cover plate 1 is a hollow structure, a plurality of threaded holes for limiting bolts are formed on the lower cover plate 2, and the lower cover plate 2 is rotatably arranged relative to the upper cover plate 1. When the two beam frames are connected, the device is first assembled with the beam frame that has been fixed, and then another beam frame is lifted by a crane, so that the end of the other beam frame slides into the upper cover plate 1 along the inclined surface formed by the lower cover plate 2. During the sliding process, the end pushes the sliding frame 5, thereby driving the sliding frame 5 to be inserted into the fixed pad 4. The sliding groove 81 formed on the sliding frame 5 and the pin rod on the support frame 8 are slidingly matched, so that the two support frames 8 slide along the fixed pad 4 from the center of the lower cover plate 2 to both sides, thereby abutting against the inner wall of the beam frame and fixing the end of the beam frame. Finally, the lower cover plate 2 is rotated and tightly attached to the bottom of the upper cover plate 1, so that the ends of the beam frames are aligned with each other, and the connecting part is transitionally buffered by the fixed pad 4. Then the bolts are screwed into the threaded holes, and the connection of the two beam frames is completed.

[0031] In the above technology, the sliding groove 81 formed on the sliding frame 5 and the pin rod on the support frame 8 are slidingly matched, so that the two support frames 8 slide along the fixed pad 4 from the center of the lower cover plate 2 to both sides, thereby abutting against the inner wall of the beam frame and fixing the end of the beam frame. Finally, the lower cover plate 2 is rotated and tightly attached to the bottom of the upper cover plate 1, so that the ends of the beam frames are aligned with each other, and the connecting part is transitionally buffered by the fixed pad 4. Then the bolts are screwed into the threaded holes, and the connection of the two beam frames is completed.

[0032] As an embodiment further provided by the present invention, a movable groove is provided on the upper cover plate 1, and the movable groove includes a through hole 13 and a rotating hole 14, and a fixing bolt 9 is provided on the lower cover plate 2 for sliding cooperation with the movable groove to switch between the through hole 13 and the rotating hole 14.

[0033] Specifically, a metal spring 10 is provided on the lower cover plate 2, and a fixing bolt 9 is provided on the metal spring 10. When it is necessary to guide the beam frame to dock, the fixing bolt 9 is plugged into the rotation hole 14. The depth of the rotation hole 14 is shallow, so that the metal spring 10 is deformed and compressed. At this time, the distance between the upper cover plate 1 and the lower cover plate 2 is large, so that the lower cover plate 2 can be rotated according to demand, so that the opening enclosed between the upper cover plate 1 and the lower cover plate 2 is large, and the end of the beam frame can easily enter the opening and be resisted by the support frame 8, and then pass through. The crane moves the end of the beam frame upward, thereby driving the lower cover plate 2 to move upward as a whole through the support frame 8. The lower cover plate 2 will move along the movable groove, causing the fixing bolt 9 to slide out of the rotating hole 14 and move upward. During this process, the metal spring 10 is continuously compressed and accumulates deformation potential energy until the fixing bolt 9 enters the through hole 13. The deformation potential energy of the metal spring 10 is released and the fixing bolt 9 is locked in the through hole 13 through its own deformation potential energy. At this time, the lower cover plate 2 and the upper cover plate 1 are tightly attached to each other, and the lower cover plate 2 is parallel to the upper cover plate 1.

[0037] Specifically, wing plates 3 are provided on both sides of the lower cover plate 2, and support rods 12 for resisting both sides of the beam frame are rotatably provided on the wing plates 3. The support rods 12 are symmetrically arranged at both ends of the transmission rod 11. A folded angle is provided on the support rod 12. The raised portion of the transmission rod 11 is flattened with the pressure of the beam frame port, driving the two ends to move toward the direction close to the wing plates 3, so that the two ends of the support rod 12 are close to each other, and the folded angle of the support rod 12 is arched and supports both sides of the beam frame port, further providing fixation.

[0038] Working principle: when connecting two beam frames, firstly, the device is assembled with the fixed beam frame, then the other beam frame is lifted by the crane, so that the fixing bolt 9 is inserted into the rotating hole 14, the rotating hole 14 is shallow in depth, so that the metal spring 10 is compressed, at this time, the distance between the upper cover plate 1 and the lower cover plate 2 is large, so that the lower cover plate 2 can rotate according to the requirement, so that the opening formed between the upper cover plate 1 and the lower cover plate 2 is large, the end of the beam frame can easily enter the opening, the end of the beam frame is slid along the lower cover plate 2, so that the end is in contact with the folding part 7 and the folding part 7 is unfolded under the pressure of the beam frame, the second end slides away from the direction of the end of the beam frame, pushes the sliding frame 5 into the fixed cushion block 4, so that the two supporting frames 8 slide from the center of the lower cover plate 2 to both sides along the fixed cushion block 4, so as to support the inner wall of the beam frame and fix the end of the beam frame, at the same time, the convex part of the transmission rod 11 is flattened under the pressure of the end of the beam frame, drives the two ends to move close to the wing plate 3, so that the two ends of the supporting rod 12 are close to each other, the folding angle of the supporting rod 12 is arched and supports the two sides of the end of the beam frame, further provides fixation, then the end of the beam frame is moved upward by the crane, so that the lower cover plate 2 is moved upward as a whole, the lower cover plate 2 is moved along the movable groove, so that the fixing bolt 9 is slid out of the rotating hole 14 and moves upward, in this process, the metal spring 10 is continuously compressed and accumulates deformation potential energy, until the fixing bolt 9 enters the through hole 13, the deformation potential energy of the metal spring 10 is released and locks the fixing bolt 9 in the through hole 13, at this time, the lower cover plate 2 and the upper cover plate 1 are close to each other and parallel to each other, so that the ends of the beam frames are aligned with each other, and the transition buffer of the connecting part is provided by the fixed cushion block 4, then the bolt is screwed into the threaded hole, the connection of the two beam frames is completed.
