Abstract
Description
Technical Field
[0001] This invention relates to the field of beam installation technology, specifically to a steel structure support beam installation device. Background Technology
[0002] Steel box girders, also known as steel plate box girders, are a common structural form for long-span bridges, named for their box-shaped cross-section. Their main body is constructed using a fully welded process, consisting of a top plate, bottom plate, web, and transverse and longitudinal diaphragms. The top plate often employs an orthotropic bridge deck design with longitudinal stiffeners, characterized by its wide, flat shape and strong bending and torsional resistance.
[0003] In the prior art, patent number CN112359701A, entitled "A Steel Box Girder," includes a bottom splice plate, a web splice plate, a central diaphragm, and a top splice plate. The web splice plate is provided with multiple L-shaped stiffening ribs distributed longitudinally, and the bottom splice plate is provided with multiple U-shaped stiffening ribs distributed longitudinally. The web splice plate extends upward beyond the top splice plate and is then fixed to the bottom of a shear connector. The shear connector is supported by an inner wall side plate on one side inside the beam segment. The inner wall side plate is fixed to the bottom splice plate. An inner wall bottom plate is provided between the two inner wall side plates and is located above the U-shaped stiffening ribs. An inclined brace is also provided between the inner wall bottom plate and the inner wall side plate. A spring is provided between the inner wall bottom plate and the U-shaped stiffening ribs. This design can reduce steel consumption, is economical, and facilitates bridge deck arching.
[0004] However, existing horizontal bracing used to support steel box girders requires insertion into the support frame during use. The horizontal bracing is then moved by rollers rotating on the surface of the support. When the surface of the horizontal bracing is uneven, the rollers at the bottom of the horizontal bracing cannot hold against the surface of the horizontal bracing, making it difficult to move the horizontal bracing.

[0030] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Please see Figures 1 to 6 The present invention provides an embodiment of a steel structure support beam installation device:
[0032] The steel structure support beam installation equipment of this embodiment includes a support and bearing structure, a lateral adaptation component, an elastic guide and positioning component, an adaptive roller drive conveying component, a spiral adjustment base component, and a power transmission linkage component.
[0033] The supporting structure includes a support frame 1, with a U-shaped plate 4 fixed to the top of the support frame 1. The U-shaped plate 4 has grooves 5 for guidance on its surface and inside. The grooves 5 provide a path for the subsequent insertion and movement of the flat connector 2. The flat connector 2 is inserted into the grooves 5 of the supporting structure. An extension plate 3 is fixed to the surface of the flat connector 2, and the flat connector 2 can move in the grooves 5.
[0034] The lateral adapter component is located in the groove 5 on the surface of the U-shaped plate 4, and includes an arc plate 8. An L-shaped plate 7 is fixed to the end of the arc plate 8, and an extension rod 22 is fixed to the surface of the L-shaped plate 7. Two sets of L-shaped plates 7 and arc plates 8 are provided in the lateral adapter component, symmetrically located on both sides of the U-shaped plate 4, forming a lateral limit on the flat connector 2.
[0035] The elastic guide positioning assembly includes a plug rod 23 inserted into the end of the extension rod 22. The extension rod 22 is provided with a second spring. The two ends of the second spring are respectively connected to the inside of the extension rod 22 and the end of the plug rod 23, which can realize the reset and adaptation of the arc plate 8 through elastic force.
[0036] The adaptive roller drive conveyor assembly includes a second roller 14 disposed in the groove 5 inside the U-shaped plate 4, a first roller 12 disposed on the surface of the arc plate 8, and a power component disposed on the U-shaped plate 4 that drives the first roller 12 and the second roller 14 to rotate, providing power for the movement of the horizontal coupling 2.
[0037] The power components are divided into a first motor 6 fixed on the surface of the U-shaped plate 4 and a second motor 10 fixed on the surface of the arc plate 8. The first motor 6 can drive the second roller 14 to rotate, and the second motor 10 can drive the first roller 12 to rotate. The second roller 14 is supported on the bottom of the flat joint 2. The surface of the U-shaped plate 4 supporting the load-bearing structure is provided with a through groove 11, and the first roller 12 can be inserted into the through groove 11 to provide clearance space for the adjustment of the first roller 12.
[0038] The power transmission linkage assembly includes a U-shaped rod 9 fixed to the surface of the sleeve ring 13, and the other end of the U-shaped rod 9 fixed to the surface of the extension rod 22 for transmitting and adjusting power.
[0039] The spiral adjustment base assembly includes a screw ring 15 screwed to the top of the support frame 1. A sleeve ring 13 that can rise and fall with the screw ring 15 is sleeved on the outside of the screw ring 15. The screw ring 15 is screwed to the top of the support frame 1. A ring groove is opened on the surface of the screw ring 15. The sleeve ring 13 is placed in the ring groove and can rotate in the ring groove and rise and fall with the screw ring 15. A lifting groove 24 is opened on the surface of the U-shaped plate 4 supporting the load-bearing structure. A lifting block 25 that can rise and fall is inserted into the lifting groove 24. An insertion rod 23 of an elastic guide positioning component is fixed on the surface of the lifting block 25, which limits the extension rod 22 to only move vertically.
[0040] The spiral adjustment base assembly is also equipped with an operation locking structure, which includes a swing rod 16 fixed to the surface of the screw ring 15, a vertical rod 17 fixed to the surface of the swing rod 16, a moving rod 19 inserted into the bottom of the vertical rod 17, the moving rod 19 being able to move inside the vertical rod 17, a top holding plate 20 fixed to one end of the moving rod 19, and a spring 18 sleeved on the surface of the moving rod 19 to form an elastic locking structure, one end of the spring 18 being connected to the end of the moving rod 19, and the other end being connected to the surface of the vertical rod 17; a limiting groove 21 is opened on the surface of the support frame 1 of the supporting load-bearing structure, the limiting groove 21 is located at the bottom of the screw ring 15, and the top holding plate 20 abuts against the surface of the limiting groove 21; when the flat coupling 2 is inserted into the groove 5, it abuts against the surface of the arc plate 8 of the lateral adapter assembly, and when the flat coupling 2 is inserted into the groove 5, the first roller 12 is located at the top of the extension plate 3.
[0041] The flat coupling 2 is lowered and pressed against the surface of the arc-shaped plate 8. Under the support of the flat coupling 2, the arc-shaped plate 8 moves to both sides. During this process, the arc-shaped plate 8 can adapt to the shape of the flat coupling 2, avoiding deformation of the flat coupling 2 due to uneven local force. The L-shaped plate 7 at the end of the arc-shaped plate 8 is connected to the extension rod 22. The extension rod 22 has a connecting rod 23 inserted inside. The extension rod 22 can move on the surface of the connecting rod 23. A second spring is set inside the extension rod 22. Its elastic force can be automatically adjusted according to the pressing force of the flat coupling 2. The second spring can pull the extension rod 22, so that the arc-shaped plate 8 returns to its initial position. The two sets of symmetrical lateral adaptation components, the arc-shaped plate 8 and the L-shaped plate 7, form a lateral limiting structure for the flat coupling, which can apply force evenly from both sides of the flat coupling 2, avoiding deformation or damage to the flat coupling due to unilateral force, and ensuring the structural integrity of the flat coupling during the transportation process.
[0042] The flat connector 2 is inserted into the groove 5, which provides a guide for the flat connector 2 to move and ensure that the flat connector 2 is conveyed along the preset path. The bottom of the flat connector 2 is pressed against the surface of the second roller 14. The first motor 6 drives the second roller 14 to rotate, which can drive the flat connector 2 to move. The arc plate 8 returns to its initial position and presses against both sides of the flat connector 2. The two sets of arc plates 8 are symmetrically distributed and form a stable limit from both sides of the flat connector 2 to prevent the flat connector 2 from shifting laterally when it moves. The first roller 12 moves to the top of the extension plate 3.
[0043] Pulling the moving rod 19 causes the top plate 20 to no longer press against the surface of the limiting groove 21. The limiting groove 21 positions the top plate 20, allowing the screw ring 15 to rotate freely after disengagement. The spring 18 of the elastic locking structure, the top plate 20, and the limiting groove 21 work together to lock the adjusted position of the screw ring 15 of the spiral adjustment base assembly. Even in a vibrating environment, the screw ring 15 will not shift, providing a reliable guarantee for the stable conveying of the horizontal coupling 2. Rotating the swing rod 16 causes the screw ring 15 to rotate with it. The swing rod 16 with its locking structure simplifies the adjustment process of the screw ring 15, allowing rotation adjustment to be completed without the need for specialized tools, reducing the difficulty of operation for construction personnel, and significantly improving on-site construction efficiency. As the screw ring 15 descends, the sleeve ring 13 and the screw ring 15 are engaged through a ring groove. The sleeve ring 13 only rises and falls with the screw ring 15 and does not rotate with it, thus avoiding interference during power transmission. The sleeve ring 13 is connected to the extension rod 22 through the U-shaped rod 9, which allows the lifting block 25 to descend in the lifting groove 24. The first roller 12 is supported on the bottom of the extension plate 3. The lifting groove 24 supporting the load-bearing structure is precisely engaged with the lifting block 25, which can limit the extension rod 22 to move only in the vertical direction, effectively preventing misalignment when the first roller 12 is adjusted, improving the accuracy of roller position adjustment, and thus ensuring the stability of power transmission.
[0044] When the bottom of the flat link 2 is uneven, the first roller 12 can support the top of the extension plate 3 and drive the first roller 12 to rotate through the second motor 10. The first roller 12 and the second roller 14 form a dual power support. Even if the bottom of the flat link 2 is uneven, the first roller 12 and the second roller 14 can still drive the flat link 2 to move, so that the flat link 2 can still be driven to move, completely solving the problem of the difficulty of moving the flat link.
[0045] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
