Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge construction, and more particularly to a through-hole auxiliary device for a bridge erection machine. Background Art
[0002] In modern bridge construction, bridge-erecting machine hole-passing auxiliary devices play a vital role. However, current technologies still face many challenges and limitations. The primary issue is the deflection of the main beam during the bridge-erecting machine hole-passing. During this process, the main beam is in a cantilevered state and, under the influence of gravity, its ends deflect. This deflection not only affects construction accuracy but can also lead to uneven structural stress distribution, potentially endangering the overall stability and service life of the bridge in the long term. Several solutions have been proposed to address this issue, but each has significant drawbacks. The counterweight method, while simple in principle, is often time-consuming and labor-intensive to implement. Adding and removing counterweights is not only time-consuming but also requires additional lifting equipment, increasing construction costs and safety risks. Furthermore, excessive counterweighting can cause the overall center of gravity of the bridge-erecting machine to shift, leading to new stability issues. While the external lifting method can effectively alleviate the deflection problem, it also faces challenges such as equipment scheduling, site requirements, and increased costs. This method is even more difficult to implement in construction environments with limited space or complex terrain. These methods not only increase construction complexity and costs but also may introduce new safety hazards, significantly reducing the efficiency and reliability of the bridge-erecting process.
[0003] To solve the above problems, some manufacturers have developed guiding devices. These devices can theoretically effectively control the position and posture of the main beam by providing guidance and support. However, the design and use of these guiding devices still have significant defects. First, the installation and disassembly process of most guiding devices is complicated, requiring professional operation and taking a long time. This not only reduces construction efficiency, but also increases the labor intensity and safety risks of workers.
[0004] In order to solve the problem of cumbersome installation and disassembly of guide devices, some manufacturers have developed quick installation and disassembly systems. These systems are designed to simplify the operating process and improve construction efficiency. However, these improvement measures still have some obvious shortcomings. First, in order to achieve rapid installation and disassembly, many designs are overly simplified, sacrificing the stability and reliability of the structure, which may lead to accidental loosening or falling off during use, seriously threatening construction safety. Secondly, some quick installation systems are difficult to withstand the huge stress and vibration during the bridge crane's hole-passing process, and are prone to deformation or damage, which not only affects the service life of the device, but may also fail at critical moments, posing serious safety hazards.

The rotating plate 13 will drive the arc groove 14 and the circular groove 15 to rotate. When the circular groove 15 moves to a position concentric with the top plate 17, the sliding sleeve 18 is pushed. The sliding sleeve 18 will drive the push rod 16 and the push rod 16 to pass through the circular groove 15. At the same time, the sliding sleeve 18 will cooperate with the rotating plate 13 to squeeze the push spring 24 set on the outside of the push rod 16. When the push spring 24 is squeezed to the limit, the corresponding top plate 17 just passes through the circular groove 15 and reaches the other side of the rotating plate 13. Then rotate the rotating plate 13 in the opposite direction.

[0042] More specifically, when the device needs to be used, first the bridge erection machine 1 is operated to pass through the hole, so that the bridge erection machine 1 moves, and then the two hydraulic cylinders 4 are opened synchronously, so that the hydraulic cylinder 4 drives the hydraulic rod 3 connected to the output end to contract. Since one end of the hydraulic cylinder 4 is rotatably connected to the connecting seat 5 set on one side of the bridge erection machine 1, one end of the hydraulic rod 3 is rotatably connected to the connecting seat 5 set on one side of the connecting rod 2, and one end of the connecting rod 2 is rotatably connected to the connecting seat 5 set on one side of the bridge erection machine 1, then the hydraulic rod 3 will drive the connecting rod 2 to move, so that the connecting rod 2 Drive the reinforcement frame 26 to rotate along the connecting seat 5 set at one end, and then close the hydraulic cylinder 4, so that the connecting rod 2 and the bridge-building machine 1 form an acute angle, and then the connecting rod 2 will contact the pulley 28 installed on the support platform 27 set on the other side, so that the pulley 28 slides, so that the reinforcement frame 26 and the connecting rod 2 form a slope to serve as a guide. When the corresponding end of the bridge-building machine 1 is completely overlapped with the support platform 27, open the hydraulic cylinder 4 again, so that the hydraulic cylinder 4 drives the hydraulic rod 3 to drive the connecting rod 2 and the reinforcement frame 26 to reset.
[0043] In summary, when the overall equipment is in use or running: when the guide device needs to be installed, first insert one end of the hydraulic cylinder 4 into the inner side of the connecting seat 5 set on one side of the bridge-building machine 1, and then pass one end of the clamping rod 8 from one side of the connecting seat 5 through the connecting seat 5 and one end of the hydraulic cylinder 4, and then rotate the rotating plate 13. The rotating plate 13 will drive the arc groove 14 and the circular groove 15 to rotate. When the circular groove 15 moves to a position concentric with the top plate 17, it pushes the sliding sleeve 18. The sliding sleeve 18 will drive the push rod 16 and the push rod 16 to pass through the circular groove 15. At the same time, the sliding sleeve 18 will cooperate with the rotating plate 13 to squeeze the push spring 24 set on the outside of the push rod 16. When the push spring 24 is squeezed to the limit, the corresponding top plate 17 just passes through the circular groove 15 and reaches the other side of the rotating plate 13, and then the rotating plate 13 is rotated in the opposite direction. , the rotating plate 13 will drive the arc groove 14 and the circular groove 15 to rotate, and then the push rod 16 will enter the arc groove 14, and then the sliding sleeve 18 will be restricted to one side of the rotating plate 13 through the cooperation of the push rod 16 and the top plate 17. At this time, the outer side of the insertion rod 19 loses the limit of the sliding sleeve 18, and then the rotating sleeve 7 is rotated, and the rotating sleeve 7 will drive the insertion rod 19 to move. Due to the rounded structure design at the end of the insertion rod 19 and the edge of the slot 20, the side wall of the slot 20 squeezes the end of the insertion rod 19, and then one end of the insertion rod 19 will slide out of the slot 20, and then the other end of the insertion rod 19 will drive the conical spring 23 to stretch, and at the same time the rotating sleeve 7 will drive the rotating groove 11 opened on the inside to move, and then the rotating groove 11 will drive the card block 9 to move through the rotating shaft 12, and then the outer wall of the card sleeve 6 squeezes one side of the card block 9, so that The card block 9 slides along the rotating shaft 12, and then the card block 9 will gradually slide out of the card slot 10 and gradually enter the rotating groove 11, and the card block 9 will squeeze the spring 22 connected on one side. When the card block 9 completely enters the rotating groove 11, the card sleeve 6 is sleeved from the other side of the connecting seat 5 to the outside of the card rod 8. When the card plate 21 connected to one side of the card sleeve 6 and one end of the card rod 8 completely clamps the connecting seat 5, the rotating sleeve 7 is rotated in the opposite direction. The rotating sleeve 7 will drive the rotating groove 11 to rotate in the opposite direction and reset, and then the rotating groove 11 will drive the card block 9 to reset through the rotating shaft 12, and then the outer wall of the card sleeve 6 will gradually no longer limit the card block 9, and then the spring 22 slowly resets to push the card block 9, so that the card block 9 rotates along the rotating shaft 12, and then the card block 9 will gradually slide out of the rotating groove 11 and enter When the push spring 24 pushes the sliding sleeve 18 to fully return to its original position, the rotating plate 13 is rotated again, so that the rotating plate 13 drives the arc groove 14 and the circular groove 15 to move to a position that does not correspond to the ejector rod 16 and the top plate 17, so that the rotating plate 13 and the ejector rod 16 cooperate to limit the sliding sleeve 18, so that the sliding sleeve 18 will not slide.Then the inner wall of the sliding sleeve 18 will limit the outer end of the rod 19 to prevent the rod 19 from sliding. Then the rod 19 will cooperate with the slot 20 to form a limit to prevent the rotating sleeve 7 from moving, thereby ensuring the stability of the connection structure and preventing the structure from loosening or even falling off.
