Technical Field

[0001] This utility model relates to the field of dismantling devices, and in particular to a Bailey beam support dismantling device. Background Technology

[0002] Bailey bridge scaffolding, also known as beam-type scaffolding, is a type of falsework structure evolved from the Bailey bridge structure. It is used as a temporary structure to support formwork or other construction loads in the cast-in-place construction of continuous beams. It features simple structure, convenient transportation, quick erection, large load-bearing capacity, good interchangeability, and strong adaptability, making it the most widely used prefabricated load-bearing component in my country. It is primarily used in bridge construction projects.

[0003] In the prior art, Chinese utility model patent with publication number "CN208668283U" and patent name "A Bailey Beam Support Dismantling Device" discloses a dismantling device. This patent describes a dismantling device comprising "a sliding track groove, a base plate, and a sliding beam. Roller assemblies are provided at both ends and the middle of the bottom of the base plate. The Bailey beam support is located on the sliding beam and connected to the sliding beam via U-shaped anchor clips. The sliding beam is set on the base plate and located within a positioning plate. The base plate, equipped with pulleys, is positioned on the sliding track groove, thus allowing the Bailey beam support to be placed on the sliding part composed of the sliding beam and the base plate. The inner Bailey beam support can be moved to the outer side along the sliding track groove by traction, and then the Bailey beam can be lifted down and dismantled by a crane.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 - Figure 4 As shown, a Bailey bridge support dismantling device includes a strip foundation 1. Several steel pipe columns 2 are fixedly connected to the top surface of the strip foundation 1, and column caps 3 are fixedly connected to the top surface of the steel pipe columns 2. Unloading blocks 4 are fixedly connected to the top surface of the column caps 3. Load-bearing beams 5 are horizontally supported on the top surface of the several unloading blocks 4. Several Bailey bridge support bodies 6 are provided on the top surface of the load-bearing beams 5. The Bailey bridge support bodies 6 are movably connected to the top surface of the load-bearing beams 5 via movable support plates 11 on their bottom surfaces. Pushing mechanisms 7 are respectively provided on the two side walls of the load-bearing beams 5. The pushing mechanism 7 includes a traveling track 13, a self-propelled trolley 14, a hydraulic cylinder 18, and a pushing plate 19. The traveling track 13 is fixedly connected to both sides of the load-bearing beams 5. The self-propelled trolley 14 is movably connected to the traveling track 13. The hydraulic cylinder 18 is fixedly connected to the L-shaped seat 17 at the front end of the load-bearing beam 5 on the top surface of the self-propelled trolley 14. The push plate 19 is fixedly connected to the output end of the hydraulic cylinder 18. The right end of the load-bearing beam 5 is also provided with a unloading mechanism 8. The unloading mechanism 8 includes an unloading protective pipe 21, a winch 26, and an unloading platform 27. The unloading protective pipe 21 is fixedly connected to the right end of the load-bearing beam 5. The winch 26 is fixedly connected to the top surface of the support frames 25 on both sides of the unloading protective pipe 21. The unloading platform 27 is movably connected to the unloading protective pipe 21 through the second sliders 28 on both sides. The unloading platform 27 is also fixedly connected to the winch 26 through the lifting lugs 29 on the outside of the second sliders 28.

[0023] like Figure 2 As shown, a set of symmetrical flanges 9 are fixedly installed on the top surface of the load-bearing beam 5, and T-shaped rails 10 are fixedly installed on the opposite walls of the symmetrical flanges 9 respectively. The T-shaped rails 10 installed on the flanges 9 are used to cooperate with the Bailey beam support body 6 to achieve sliding displacement operation.

[0024] like Figure 2As shown, the Bailey beam support body 6 is fixedly installed on the top surface of the movable pallet 11, and T-shaped sliding grooves 12 corresponding to the T-shaped track 10 are respectively opened on the two side walls of the movable pallet 11 and are movably connected between the side guards 9 through the T-shaped sliding grooves 12. When the movable pallet 11 moves along the T-shaped track 10 through the T-shaped sliding grooves 12, it will drive the Bailey beam support body 6 to achieve synchronous movement operation.

[0025] like Figure 3 As shown, two sides of the outer wall of the load-bearing beam 5 are respectively fixedly installed with traveling rails 13, and a self-propelled trolley 14 is movably installed on the traveling rails 13. A fixed platform 15 is fixedly installed on the top of the self-propelled trolley 14, and a first sliding opening 16 is opened on the right side of the top surface of the fixed platform 15. An L-shaped seat 17 is fixedly installed on the right side of the front end of the fixed platform 15, and a hydraulic cylinder 18 is fixedly installed on the front wall of the L-shaped seat 17. A push plate 19 is fixedly installed on the output end of the hydraulic cylinder 18, and the bottom surface of the push plate 19 is fixedly installed with... Equipped with a first slider 20, which is movably installed in the first sliding port 16, the self-propelled trolley 14 moves along the travel track 13 to the left rear of the Bailey beam support body 6. Then, the hydraulic cylinder 18 is activated to drive the output end to push the push plate 19 to the rear end of the Bailey beam support body 6. When the travel track 13 moves to the right again, it can push the Bailey beam support body 6 towards the unloading mechanism 8, so as to achieve the purpose of pushing the Bailey beam support body 6 on the load-bearing beam 5 one by one.

[0026] like Figure 4 As shown, the unloading protective pipe 21 is fixedly installed on the top surface of the strip foundation 1 and located at the right end of the load-bearing beam 5. The unloading protective pipe 21 has an unloading port 22 on the top of its left side wall. The unloading port 22 allows the Bailey beam support body 6 to enter the unloading protective pipe 21. The unloading protective pipe 21 can avoid safety hazards when disassembling the Bailey beam support body 6. The unloading protective pipe 21 has an outlet 23 on the bottom of its right side wall. The outlet 23 allows the Bailey beam support body 6 to be taken out when it falls to the ground. The unloading protective pipe 21 has vertical second sliding openings 24 on its front and rear side walls. The second sliding openings 24 are used to cooperate with the second slider 28 to achieve sliding operation. The unloading protective pipe 21 also has support frames 25 fixedly installed on the top of its front and rear side walls. The support frames 25 are used to cooperate with the installation of the winch 26.

[0027] like Figure 4As shown, the winch 26 is fixedly installed on the top surface of the support frame 25. Second sliders 28 are fixedly installed on both sides of the unloading platform 27, and the second sliders 28 are movably installed in the second sliding opening 24. Lifting lugs 29 are fixedly installed on the outer side of the second sliders 28, and the hooks at the upper ends of the winch 26's winding and unwinding steel cables are hung and fixedly installed together with the lifting lugs 29. After the Bailey beam support body 6 moves to the unloading platform 27 in the unloading protective pipe 21, the winch 26 will control the unwinding and unwinding of the steel cable, so that the unloading platform 27 moves downward in the unloading protective pipe 21 along the second sliding opening 24 through the second sliders 28 on both sides until the Bailey beam support body 6 is moved to the discharge port 23.

[0028] It should be noted that this utility model is a Bailey beam support dismantling device. When dismantling the Bailey beam support body 6, the self-propelled trolleys 14 on both sides of the load-bearing beam 5 are activated, allowing the self-propelled trolleys 14 to move along the travel tracks 13 installed on both sides of the load-bearing beam 5 to the left rear part of the Bailey beam support body 6 at the rightmost and outermost end of the top surface of the load-bearing beam 5. Then, the hydraulic cylinder 18 installed on the front wall of the L-shaped seat 17 on the right side of the front end of the fixed platform 15 is activated. The hydraulic cylinder 18 pushes the push plate 19 inward. The first slider 20 installed on the bottom surface of the push plate 19 slides within the first sliding opening 16 opened on the top surface of the fixed platform 15 until the push plate 19 moves to the rear end of the Bailey beam support body 6. The self-propelled trolley 14 is started, causing it to move to the right along the travel track 13. During this movement, the pusher plate 19, positioned behind the Bailey beam support body 6, pushes the Bailey beam support body 6 to the right. The movable support plate 11 mounted on the bottom surface of the Bailey beam support body 6 slides along the T-shaped sliding grooves 12 on both side walls, following the symmetrical sidewalls 9 mounted on the top surface of the load-bearing beam 5 and the T-shaped track bars 10 on the opposite wall, until the Bailey beam support body 6 moves through the unloading port 22 on the top left side wall of the unloading pipe 21 and falls onto the top surface of the unloading platform 27 inside the unloading pipe 21. Subsequently, the hydraulic cylinder 18 drives the pusher plate 19 back to its original position and automatically... The trolley 14 moves to the left along the track 13 to the left rear of the Bailey beam support body 6, which is currently located on the far right, in preparation for the next push of the Bailey beam support body 6. At the same time, the winch 26 installed on the top surface of the support frame 25 will drive and unwind the coiled steel cable. During unwinding, because the hook at the end of the steel-plastic cable is fixed to the lifting lug 29, it will drive the unloading platform 27 to move downward inside the unloading protective tube 21. During the movement, the second sliders 28 installed on both sides of the unloading platform 27 will slide within the second sliding openings 24 on both sides of the unloading protective tube 21 until the unloading platform 27 moves to the bottom of the unloading protective tube 21, and the Bailey beam support body 6 is placed at the bottom right side of the unloading protective tube 21. The Bailey beam support body 6 can be removed through the discharge port 23. After removal, the winch 26 will rewind the unwinding steel cable to move the unloading platform 27 upward back to its original position to prepare for the next unloading operation. Finally, the above steps are repeated until all Bailey beam support bodies 6 on the load-bearing beam 5 are removed. This achieves the purpose of quick disassembly and assembly of the Bailey beam support body 6. The structure is simple and can be operated by workers on the ground without the need for workers to work at height. This not only reduces the safety hazards that may occur when working at height, but also ensures the personal safety of workers and improves the disassembly efficiency of the Bailey beam support body 6.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
