Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of bridge construction equipment, and particularly relates to a mobile suspended platform device for bridge construction. Background Technology
[0002] In bridge construction, suspended platform equipment is a core tool for high-altitude operations (such as bridge side painting, crack repair, and bearing inspection). Existing suspended platforms for bridge construction mainly suffer from the following problems: 1. Poor mobility: Most suspended platforms rely on external traction equipment (such as winches and cranes) to adjust their position. During the movement, they are easily restricted by the bridge structure, and the positioning accuracy is low. Multiple adjustments are required, which seriously affects the work efficiency. 2. Poor stability and safety: Some suspended platforms are only fixed by ropes or simple supports, which can easily slip or tilt due to wind or vibration during operation, posing a safety hazard. 3. Cumbersome assembly and disassembly: The components of the integrated suspended platform are complex to connect, and on-site assembly and disassembly require a lot of manual labor, which not only increases the labor intensity of construction workers, but also prolongs the equipment deployment and recovery time, affecting the construction progress.
[0003] Therefore, it is necessary to provide a new type of mobile suspended platform equipment for bridge construction to solve the above-mentioned technical problems. Summary of the Invention
[0004] The technical problem solved by this invention is to provide a mobile suspended platform for bridge construction that can achieve autonomous and stable movement, modularly adapt to different bridge sizes, has a firm and anti-slip positioning, is lightweight and meets safety protection standards, and is easy to assemble and disassemble, reducing construction intensity.
[0005] To solve the above-mentioned technical problems, the mobile suspended platform equipment for bridge construction provided by the present invention includes: two modular working platforms, multiple guide rail assemblies, two drive mechanisms, multiple positioning mechanisms, and multiple connecting components; The modular work platform includes a spreader beam A, a spreader beam B, two long connecting beams, two suspended railing platforms, multiple screw assemblies, and four support wheels. The two long connecting beams are fixedly installed between spreader beam A and spreader beam B. The two suspended railing platforms are symmetrically arranged below spreader beam A and spreader beam B. Multiple adjusting screws are installed on the suspended railing platforms and pass through spreader beam A and spreader beam B respectively. The four support wheels are fixedly installed at the bottom of spreader beam A and spreader beam B respectively. The screw assembly includes an adjusting screw and two adjusting nuts, with the two adjusting nuts threaded onto both ends of the adjusting screw, respectively. Two short connecting beams are provided between the two spreader beams B. Both ends of the short connecting beams are threaded with fixing bolts, which pass through the spreader beams B.
[0006] As a further embodiment of the present invention, the guide rail assembly includes a guide rail, a fixing plate, and a rack. The guide rail is disposed on the top of the bridge, the fixing plate is fixedly installed on one side of the guide rail, and the rack is fixedly installed on the top of the fixing plate.
[0007] The guide rails provide a track for the support wheels, ensuring stable movement of the equipment.
[0008] As a further embodiment of the present invention, the driving mechanism includes a strip-shaped mounting plate, two side plates, a dual-axis motor, two drive shafts, and two gears. The strip-shaped mounting plate is fixedly mounted on the bottom of the spreader beam A. Both side plates are fixedly mounted on the bottom of the strip-shaped mounting plate. The dual-axis motor is fixedly mounted on the bottom of the strip-shaped mounting plate. The two drive shafts are respectively fixedly mounted on the two output shafts of the dual-axis motor. The two drive shafts pass through the two side plates and are rotatably connected to the side plates. The two gears are respectively fixedly mounted on one end of the two drive shafts, and the gears mesh with the rack.
[0009] The dual-axis motor drives the drive shaft to rotate, which in turn drives the gears to roll along the rack, thereby enabling the entire equipment to move stably along the guide rail and improving work efficiency.
[0010] As a further embodiment of the present invention, the positioning mechanism includes a vertical plate, a hydraulic cylinder, and a rectangular plate. The vertical plate is fixedly installed at the bottom of the long connecting beam, the hydraulic cylinder is fixedly installed on the vertical plate, and the rectangular plate is fixedly installed on the output shaft of the hydraulic cylinder.
[0011] By activating the hydraulic cylinder to push the rectangular plate against the side of the bridge, the equipment is positioned and fixed during operation, preventing accidental slippage and improving operational safety.
[0012] As a further embodiment of the present invention, connecting seats are fixedly installed on both sides of the guide rail assembly, and C-shaped inserts are fitted into the corresponding two connecting seats, with handles fixedly installed on the top of the C-shaped inserts.
[0013] The connecting seats of adjacent guide rail components are engaged by the C-shaped inserts, enabling the rapid splicing of multiple guide rail sections, adapting to the needs of bridge operations of different lengths, and the handles facilitate the installation and removal of the inserts.
[0014] As a further embodiment of the present invention, a level is fixedly installed on the top of the long connecting beam.
[0015] The level instrument monitors the horizontal status of the work platform in real time, allowing operators to adjust the platform's level promptly by adjusting the screws, thus preventing platform tilting and potential safety accidents.
[0016] As a further embodiment of the present invention, multiple connecting components are installed on each of the two corresponding suspended fence platforms. Each connecting component includes a fixing bolt and two fixing nuts. The fixing bolt passes through both suspended fence platforms, and the two fixing nuts are threaded onto both ends of the fixing bolt.
[0017] The connection between the two suspended platforms is reinforced by fixing bolts and nuts, which improves the overall structural stability of the platform and prevents the platform from shifting during operation.
[0018] As a further embodiment of the present invention, both ends of the spreader beam A and spreader beam B are equipped with hanging plates, and the hanging plates are provided with hanging holes.
[0019] The use of lifting holes in conjunction with hoisting equipment facilitates the transportation, installation, and dismantling of the entire modular work platform, reducing on-site construction intensity.
[0020] As a further embodiment of the present invention, the suspended fence platform is made of hollow steel pipe, and the fence height of the suspended fence platform is 1.2m.
[0021] The hollow steel pipes reduce the platform's weight while ensuring structural strength, and the 1.2m high railing meets the safety protection standards for high-altitude operations, preventing personnel or tools from falling.
[0022] As a further embodiment of the present invention, both the long connecting beam and the short connecting beam are made of square steel with a cross-sectional dimension of 100*100 mm.
[0023] 100*100 mm square steel has high bending and shear strength, which can stably support the weight of workers and tools, and ensure the overall structural rigidity of the equipment.
[0024] Compared with related technologies, the mobile suspended platform equipment for bridge construction provided by the present invention has the following beneficial effects: 1. This invention, by setting up a modular operating platform, allows for modular assembly of the operating platform, reducing assembly and usage costs, and its lightweight structure significantly reduces construction intensity. 2. By setting up guide rail components and connecting components, the guide rail can be quickly spliced through C-shaped inserts to adapt to bridges of different lengths. The guide rail provides a stable track for the support wheels. In conjunction with the gear and rack transmission of the drive mechanism, it ensures the precise movement direction of the equipment and avoids the problem of movement deviation. 3. By setting up a drive mechanism, the dual-axis motor drives the gear to roll along the rack, realizing the autonomous and stable movement of the equipment and significantly shortening the construction cycle; 4. By setting up a positioning mechanism, the hydraulic cylinder pushes the anti-slip rectangular plate to press against the side of the bridge, thus fixing the position of the working platform and effectively avoiding safety hazards.

[0029] like Figure 5 As shown, the guide rail assembly includes a guide rail 10, a fixing plate 11, and a rack 12. The guide rail 10 is disposed on the top of the bridge, the fixing plate 11 is fixedly installed on one side of the guide rail 10, and the rack 12 is fixedly installed on the top of the fixing plate 11. The guide rail 10 provides a moving track for the support wheel 7, ensuring the stability of the equipment's movement direction.
[0030] like Figure 5 As shown, the drive mechanism includes a strip mounting plate 13, two side plates 14, a dual-axis motor 15, two drive shafts 16, and two gears 17. The strip mounting plate 13 is fixedly installed at the bottom of the spreader beam A1. The two side plates 14 are both fixedly installed at the bottom of the strip mounting plate 13. The dual-axis motor 15 is fixedly installed at the bottom of the strip mounting plate 13. The two drive shafts 16 are respectively fixedly installed on the two output shafts of the dual-axis motor 15.

The two gears 17 are respectively fixedly installed at one end of the two drive shafts 16, and the gears 17 mesh with the rack 12. The dual-axis motor 15 drives the drive shaft 16 to rotate, which in turn drives the gear 17 to roll along the rack 12, thereby enabling the entire equipment to move stably along the guide rail 10 and improving work efficiency.

[0038] The working principle of the mobile suspended platform equipment for bridge construction provided by this invention is as follows: First step: Lay multiple sections of guide rail 10 on the top of the bridge, use C-shaped inserts 22 to engage adjacent connecting seats 21 to complete the splicing of multiple sections of guide rail. Assemble two modular work platforms on the ground on the side of the bridge. Hoist the first modular work platform onto the guide rail 10 on the top of the bridge using hoisting equipment so that the support wheel 7 contacts the guide rail 10 and the gear 17 meshes with the rack 12. After hoisting the second modular work platform, place the short connecting beam 8 between the two flat beams B2 and connect and fix it with fixing bolts 9. Finally, connect and reinforce the two adjacent fence platforms 4 with fixing bolts 25 and fixing nuts 26. Observe the level 24. If the platform is tilted, turn the adjusting nut 6 to adjust the height of the hoisting fence platform 4 until the platform is level. The second step: When in use, start the hydraulic cylinder 19 to push the rectangular plate 20 against the side of the bridge to complete the positioning and prevent the platform from moving accidentally during use. When it is necessary to move, retract the hydraulic cylinder 19 to release the positioning, start the dual-axis motor 15 through the controller to drive the equipment to move along the guide rail 10 to the designated working position, turn off the dual-axis motor 15, and reposition the working platform. Third step: After the operation is completed, remove the fixing nuts 26 of the fixing bolt 25 and the fixing bolts 9 of the short connecting beam 8 to disassemble the two modular work platforms; remove the C-shaped inserts 22 of the guide rail assembly and disassemble the guide rail 10 in sections; use hoisting equipment to hoist the disassembled components to the ground to complete the equipment recovery.
