Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, specifically to a pre-lead beam structure that is easy to recycle. Background Technology

[0002] With the rapid development of my country's economy, road and bridge engineering has entered a period of high-speed development. In the construction of continuous rigid frame bridges, the use of cantilever construction with hanging baskets can ensure the construction cycle of segments while fully guaranteeing safety, thus ensuring the construction alignment and quality, and also ensuring the aesthetic appearance of the structure. In traditional processes, hanging baskets are assembled and used. After the closure section is completed, the leading beam, which serves as the load-bearing inner formwork system within the box girder, is often not removed as a whole due to its large length. The common solution on construction sites is to cut the leading beam and remove it in sections, but at this point, the leading beam cannot be reused, which is quite wasteful. Utility Model Content

[0030] Working principle of this utility model:

[0031] First, one end of the hydraulic cylinder 4 abuts against the side wall of the first-stage guide beam section 1, driving the first motor 6. The first motor 6 drives the second gear 9 to rotate. Under the action of the second gear 9, the first gear 7 drives the double-threaded rod 8 to rotate. Under the action of the rotation of the double-threaded rod 8, the pair of clamping frames 11 move closer or further apart, thus facilitating the clamping and fixing of the hydraulic cylinder 4. When the pair of clamping frames 11 move, they can move on the guide rod 10. The guide rod 10 stabilizes the movement of the pair of clamping frames 11. When it is necessary to limit the movement of the second-stage guide beam section 2, the second motor 24 is driven. The second motor 24 drives the transmission block 19 to move. The transmission block 19 moves on the slide rail 16 through the sliding block 18. The transmission block 19 is movable and stable. Under the action of the transmission block 19, the connecting frame 20 drives the limiting rod 21 to move. When the moving wheel 22 contacts the abutment block 13, the connecting frame 20 moves towards the transmission block 19, and the limiting rod 21 moves with the connecting frame 20. The end of the connecting frame 20 away from the moving wheel 22 enters the limiting hole 25 on the secondary guide beam section 2, thereby fixing the secondary guide beam section 2, increasing the strength of the front guide beam, and facilitating work. After the work is completed, the second motor 24 is driven to reverse, the limiting rod 21 moves away from the limiting hole 25, and the hydraulic cylinder 4 can drive the secondary guide beam section 2 to move and be stored in the primary guide beam section 1, making it easy to take out the whole and thus facilitating recycling.
