Description

Technical Field

[0001] This utility model relates to the field of drainage technology for the middle deck of a split bridge, and more specifically, to a movable suspended platform for bridge deck drainage. Background Technology

[0002] With the continuous expansion of bridge construction, the maintenance and repair of bridge deck drainage systems have become a crucial aspect of ensuring the safe operation of bridges. As a common bridge structure, the drainage systems of separated bridges are exposed to the natural environment for extended periods, making them susceptible to blockages and damage due to rainwater erosion and debris accumulation. Regular cleaning and maintenance are therefore necessary.

[0003] However, existing bridge deck drainage systems have the following problems when in use:

[0004] When constructing drainage systems in the middle of a separated bridge deck, the limited space makes it difficult for conventional construction trolleys to access and operate. Furthermore, the complex and varied terrain beneath the bridge presents challenges such as operational limitations and instability with aerial work platforms, potentially preventing access to the work area altogether. This results in low construction efficiency and significant safety hazards. In addition, traditional maintenance methods often require temporary scaffolding, which is not only time-consuming and labor-intensive but also poses potential damage to the bridge structure, increasing maintenance costs.

[0005] This utility model allows for flexible movement of the suspended platform via crossbars and rollers, and ensures stability by using limit rods. Combined with high-strength suspension ropes, a modular suspended platform, and cross support rods, it facilitates safe and efficient maintenance and cleaning of the bridge deck drainage system by operators, improving maintenance efficiency and safety. Summary of the Invention

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a movable suspended basket for bridge deck drainage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a movable suspended platform for bridge deck drainage, comprising: a bridge body, a crossbar slidably connected to the upper end of the bridge body, a suspension rope detachably connected to the bottom of the crossbar, the crossbar being slidably installed between two bridge bodies, the suspension rope being located between the bridge bodies, and a suspended platform being fixedly connected to the bottom of the suspension rope.

[0008] A further preferred embodiment: Limiting rods are fixedly installed at both ends of the crossbar, and the limiting rods are located on the outer end faces of the two bridge bodies respectively.

[0009] A further preferred embodiment: the limiting rod is L-shaped.

[0010] A further preferred embodiment: a roller is fixedly installed at the bottom of the crossbar, the roller is movably connected to the upper end of the bridge body, and rolls on the upper end of the bridge body.

[0011] A further preferred embodiment: the suspension rope is made of high-strength steel wire rope.

[0012] A further preferred embodiment: the suspended platform is assembled at the upper end of the bridge body, and a support rod is fixedly installed inside.

[0013] A further preferred embodiment: the support rods are distributed in a crisscross pattern. Beneficial effects

[0014] 1. Equipped with crossbars, limit bars, and rollers, the crossbars are mounted on the upper part of the bridge structure via rollers. Utilizing their rolling characteristics, they can slide freely along the bridge surface, enabling rapid adjustment of the working position without frequent disassembly and assembly, greatly improving work efficiency. The L-shaped limit bars are attached to the outer end face of the bridge structure and fixed by a detachable structure, effectively preventing lateral displacement of the crossbars. This ensures the stability of the device while providing a safe working environment for operators. The presence of rollers significantly reduces the resistance to the movement of the crossbars, allowing a single person to easily push the device, reducing labor costs. At the same time, this structure eliminates the need for large equipment such as cranes, lowering the operational threshold and construction costs. It is suitable for the maintenance of drainage systems on various types of bridges, efficiently completing tasks whether for long-distance continuous operations or localized maintenance in complex environments.

[0015] 2. The support rods, arranged in a crisscross pattern, provide a solid guarantee for the operation of the suspended platform. Their interlocking layout, like a stable network, evenly distributes the weight of personnel and tools carried by the platform to all sides, effectively suppressing local deformation. Even when personnel move or encounter wind interference, it can greatly reduce the swaying of the platform, thus building a solid safety line for high-altitude operations. In addition, the modular splicing design of the support rods and the suspended platform complements each other, allowing for simultaneous installation during assembly and simplifying the operation process.

[0016] 3. In summary, this type of movable suspended platform for bridge deck drainage, through its structure including crossbars, limit bars, rollers, lifting ropes, a suspended platform, and support rods, provides the device with flexible mobility by combining crossbars with rollers, allowing for quick switching of work points. The limit bars ensure the stability of the crossbars and prevent the risk of lateral displacement. The high-strength lifting ropes are strong in load-bearing capacity and corrosion-resistant, and when used with the modular suspended platform, they not only meet the needs of different working depths but also facilitate transportation and maintenance. The cross-distributed support rods evenly distribute the load of the suspended platform, reduce swaying, and create a stable platform for workers. The entire device works in synergy, effectively improving the efficiency, safety, and economy of bridge deck drainage system maintenance. Attached Figure Description

[0021] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0022] Please see Figure 1-3In this embodiment of the utility model, a movable suspended platform for bridge deck drainage includes: a bridge body 1, a crossbar 2 slidably connected to the upper end of the bridge body 1, a suspension rope 3 detachably connected to the bottom of the crossbar 2, the crossbar 2 being slidably installed between two bridge bodies 1, the suspension rope 3 being located between the bridge bodies 1, a suspended platform 301 fixedly connected to the bottom of the suspension rope 3, limit rods 201 fixedly installed at both ends of the crossbar 2, the limit rods 201 being located on the outer end faces of the two bridge bodies 1 respectively, the limit rods 201 being L-shaped, and rollers 202 fixedly installed at the bottom of the crossbar 2. 2 is movably connected to the upper end of bridge body 1 and rolls on the upper end of bridge body 1. The crossbar 2 is supported on the upper end of bridge body 1 by rollers 202 at both ends. Utilizing the rolling characteristics of the rollers, it can slide freely along the length of the bridge body, realizing the adjustment of the crossbar's position on the bridge surface. The L-shaped limiting rods 201 at both ends of the crossbar 2 are respectively attached to the outer end face of bridge body 1 and fixed by detachable structures such as bolts or buckles to prevent the crossbar from shifting laterally and ensure the stability of the device. The suspension rope 3 is detachably connected to the bottom of the crossbar 2 by hooks, bolts, etc., and the lower end of the suspension rope is fixed to the basket 3. 01. After completing the overall installation, when it is necessary to inspect or clean the bridge deck drainage system, loosen the fixing structure of the limiting rod 201, push the crossbar 2 to slide along the bridge body 1, and move the basket to above the target work area. After reaching the designated position, fix the crossbar 2 to the outside of the bridge body 1 again using the limiting rod 201 to ensure that the device will not slide during the operation. Adjust the length of the hoisting rope 3 through the detachable connection structure (such as quick-release buckle), and lower the basket 301 to the vicinity of the drainage system under the bridge deck (such as the location of drainage pipes and drainage channels). Enter the suspended platform and use tools to install, clean, inspect, or maintain the drainage system, such as unblocking blockages and replacing parts. After the work is completed, retract the hoisting rope 3, raise the suspended platform to a position close to the crossbar 2, fix the hoisting rope, release the limit bar 201 again, slide the crossbar to the next work area, and repeat the fixing and lowering process until the maintenance of the entire bridge drainage system is completed. After the work is completed, disconnect the connection between the hoisting rope 3 and the crossbar 2, remove the suspended platform 301, disassemble the limit bar 201, and remove the crossbar 2 from the bridge body 1 for easy storage or transportation.

[0023] In this embodiment of the utility model, the suspension rope 3 is made of high-strength steel wire rope. The suspended basket 301 is spliced ​​on the upper end of the bridge body 1, and a support rod 302 is fixedly installed inside. The support rod 302 is distributed in a cross pattern. The steel wire rope is made of multiple strands of steel wire twisted together, which can bear the weight of the suspended basket itself, the weight of the workers and tools, avoid the risk of breakage, and has strong wear resistance and corrosion resistance. It is suitable for complex environments such as dampness and high dust on the outside of the bridge, extending the service life of the device. The steel wire rope has good flexibility and can easily adjust the lowering height of the suspended basket through pulleys or buckles to meet different working depth requirements (such as the maintenance of drainage pipes under the bridge deck). It is combined with the detachable connection structure at the bottom of the crossbar (such as... U-shaped clamps and shackles enable quick assembly and disassembly, improving work efficiency. The suspended platform is assembled from multiple modules at the top of the bridge, eliminating the need for overall hoisting, facilitating transportation and storage. In case of partial damage, individual modules can be replaced, reducing maintenance costs (e.g., if a base plate is damaged, only that part needs to be replaced). The modular design allows for flexible adjustment of the suspended platform size according to the bridge deck width and drainage system location (e.g., extending or shortening the side plates), adapting to different bridge structures. The support rods 302 are distributed in a crisscross pattern, evenly distributing the load of the suspended platform to each side, reducing local deformation, suppressing swaying of the suspended platform during operation (e.g., personnel movement, wind influence), and improving stability, making it particularly suitable for high-altitude operations.

[0024] Working principle: Rollers 202 at both ends of the crossbar 2 are mounted on the upper ends of the two bridge bodies 1. The crossbar 2 is pushed to slide along the length of the bridge body 1 to a suitable starting position, ensuring that the rollers 202 are tightly fitted to the upper end of the bridge body 1 and can roll smoothly. L-shaped limiting rods 201 at both ends of the crossbar 2 are respectively attached to the outer end faces of the two bridge bodies 1 and fixed using bolts or clips or other detachable structures. After fixing, the stability of the limiting rods 201 is checked to ensure that the crossbar 2 does not shift laterally. At the upper end of the bridge body 1, the modules of the suspended platform 301 are assembled, using bolts, clips, and other connectors to ensure tight assembly. After completion, the cross-shaped support rods 302 are fixed inside the suspended platform 301 to enhance the structural strength of the platform. One end of the lifting rope 3 is connected to the bottom of the crossbar 2 using hooks, bolts, or shackles, while the other end is fixedly connected to the suspended platform 301. The fixing structure of the limiting rod 201 is loosened, and the crossbar 2 is pushed. Utilizing the rolling characteristics of the rollers 202 on the upper part of the bridge body 1, the suspended platform 301 is moved above the target work area. Once it reaches the designated position, the limiting rod 201 is again fixed to the outside of the bridge body 1 using bolts or clips to ensure that the crossbar 2 does not slip during operation. Detachable connections are made using quick-release clips, etc. The structure is adjusted, the length of the hoisting rope 3 is adjusted, and the suspended basket 301 is slowly lowered to the vicinity of the drainage system under the bridge deck, such as the working position of drainage pipes and drainage channels. During the lowering process, care is taken to maintain the balance of the suspended basket to avoid collision with the bridge structure. After the workers put on safety protective equipment, they enter the suspended basket 301 and use the tools they carry to install, clean, inspect, or maintain the drainage system, such as unblocking blocked pipes, replacing damaged parts, and checking the sealing of the drainage system. During the operation, attention must be paid to their own safety and the stability of the suspended basket at all times. After completing the task at the current work point, the suspended basket 301 is raised to near the crossbar 2 by tightening the hoisting rope 3. Position the basket by securing the hoisting rope 3 with clips or bolts to ensure its stability. Then, loosen the limit rod 201 again and push the crossbar 2 along the bridge body 1 to the next work area. Repeat the process of moving, positioning, fixing, and lowering the basket until the maintenance of the entire bridge drainage system is completed. After the work is completed, disconnect the connection between the hoisting rope 3 and the crossbar 2, remove the basket 301, and disassemble it into splicing modules. Remove the limit rod 201 and remove the crossbar 2 from the bridge body 1. Store the high-strength steel wire rope, splicing modules, crossbar 2, limit rod 201, and other components in a dry and ventilated warehouse to prevent damage to the components for future use.
