A protective structure for unloading platforms on irregular floors and its construction method

Abstract

This invention discloses a protective structure and construction method for an unloading platform on irregular floors, relating to the field of unloading platform technology. To improve the protective effect, a bending assembly is installed at the bottom of the platform support plate. The bending assembly includes a movable plate and an elastic element for connecting two movable plates. The elastic element includes a U-shaped frame and a locking block, which are welded to the outer walls of both sides of the movable plate. A central shaft is embedded and fixed in a through hole inside the locking block. Through the design of the bending assembly, when the output end of the first telescopic component remains stationary, the output end of the second telescopic component drives the end movable plate to move, causing the end movable plate to deflect relative to the middle movable plate. This causes the second coil spring to deform, changing the arrangement of multiple movable plates from a straight line to an arc until they fit against the building facade, thereby sealing the gap between the platform support plate and the building facade and preventing construction workers from falling due to missteps.

Description

Technical Field

[0001] This invention relates to the field of unloading platform technology, and in particular to a protective structure for unloading platforms on irregular floors and its construction method. Background Technology

[0002] In the field of modern construction, unloading platforms are key facilities connecting building floors with external construction areas. Their safety and stability are directly related to the life safety of construction workers and construction efficiency. With the continuous innovation of building design, more and more buildings are presenting irregular facade shapes, such as arcs and waves. This brings unprecedented challenges to the installation and protection of unloading platforms. Traditional unloading platform designs are often based on flat or regular-shaped buildings. Their protective structures are mostly fixed or simple adjustable, which are difficult to adapt to the complex changes of irregular building facades. When the unloading platform extends to irregular building facades such as arcs, gaps are likely to appear between the platform end and the building. This not only increases the risk of construction workers falling into the gap, but may also cause materials to fall due to excessive gaps, affecting construction safety and the surrounding environment.

[0003] To address this issue, some tentative solutions have emerged in the market, such as adding temporary support structures. However, these methods often suffer from problems such as complex installation, high costs, and unstable protective effects. In particular, when facing complex facades such as curved surfaces, ensuring a tight fit between the unloading platform and the building, as well as providing comprehensive and effective protection, has become a pressing technical challenge in the current construction industry.

[0004] Therefore, developing a protective structure for unloading platforms that can adapt to irregular building facades, especially curved facades, is of great significance for improving construction safety, reducing construction risks, and protecting the lives of construction workers. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a protective structure for unloading platforms on irregular floors and its construction method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective structure for an unloading platform on an irregular floor includes a bending assembly installed at the bottom of a platform support plate. The bending assembly includes a movable plate and an elastic element for connecting two movable plates. The elastic element includes a U-shaped frame and a locking block. The U-shaped frame and the locking block are respectively welded to the outer walls of both sides of the movable plate. A central shaft is embedded and fixed in a through hole inside the locking block. Adjacent U-shaped frames and the central shaft are movably connected. A coil spring is installed between the outer circumference of the central shaft and the outer bottom wall of the U-shaped frame. Telescopic component one and telescopic component two are respectively installed at the bottom of the platform support plate. The output end of telescopic component one is fixedly connected to the movable plate in the middle through a connecting plate one. The output ends of the two telescopic components two are movably connected to the movable plates at both ends through a connecting plate two.

[0008] Preferably, the telescopic component one includes a vertical plate and an electric telescopic rod two. The vertical plate is fixed to the outer wall of one side of the platform support plate, and the electric telescopic rod two is fixed to the outer wall of one side of the vertical plate. The connecting plate one is fixed to the output end of the electric telescopic rod two by a pin, and the connecting plate one is fixedly connected to the movable plate located in the middle.

[0009] Furthermore: the telescopic component two includes a movable block and a guide rod. The guide rod is fixed to the inner wall of one side of the platform support plate, and the movable block is movably connected to the outer wall of the guide rod. A rectangular block is movably connected to the bottom of the movable block.

[0010] Furthermore: an electric telescopic rod is fixed to one side of the outer wall of the rectangular block, and a connecting plate is fixed to the output end of the electric telescopic rod by a pin, and the connecting plate and the movable plate located at the end are movably connected.

[0011] As a preferred embodiment of the present invention: a winding roller is movably connected to the through holes on both sides of the platform support plate, and a nylon protective net is wound around the outer circumference of the winding roller, and the end of the nylon protective net away from the winding roller is fixedly connected to the top of multiple movable plates.

[0012] As a further aspect of the present invention: a coil spring is installed between the outer circumferential wall of the winding roller and the side wall of the platform support plate.

[0013] As a further embodiment of the present invention: a lateral support plate is welded to the top outer wall of the platform support plate, and slides are fixed to the inner walls on both sides of the lateral support plate. A slider is movably connected to the outer wall of the slide, and a lateral moving plate is movably connected to the bottom of the slider. The bottom and top of the moving plate at the end of the lateral moving plate are movably connected.

[0014] Based on the aforementioned scheme: a sliding plate is fixed between the inner walls on both sides of the bottom of the platform support plate, and a middle seat is movably connected to the sliding groove opened on the inner wall of the top of the sliding plate, and a support frame is movably connected to the side wall of the middle seat, and a traction plate is movably connected to the bottom of the support frame, and the traction plate and the side wall of the moving plate are fixedly connected.

[0015] Based on the aforementioned scheme: both sides of the movable plate are welded with receiving plates, and the same tension spring is connected between two adjacent receiving plates.

[0016] A construction method for a protective structure for an unloading platform on an irregular floor includes the following steps:

[0017] S1: Install ground anchor bolts on the floor to fix the supporting steel structure to the ground anchor bolts, thus completing the fixing of the platform support plate;

[0018] S2: After the platform support plate is fixed, control the electric telescopic rod two to drive the connecting plate one and the middle moving plate to move so that they fit against the building facade. At this time, the output end of the electric telescopic rod one is stationary, and the moving plate at the end slides along the guide rod with the corresponding moving block under the drive of the electric telescopic rod two.

[0019] S3: After the middle movable plate is attached, the output end of the second electric telescopic rod is stationary, and the output end of the first electric telescopic rod drives the second connecting plate to move, so that the multiple movable plates change from a straight line arrangement to an arc arrangement until they are attached to the exterior of the building.

[0020] S4: When the middle and end moving plates move, the nylon protective netting is pulled along the winding roller to be unwound and laid in the gap between the platform support plate and the building facade to increase the protection range. The coil spring is used to ensure that the nylon protective netting is taut when it is rolled up.

[0021] S5: When the middle moving plate moves laterally, the end moving plate drives the lateral moving plate and the slider to slide along the slide. When the end moving plate is in contact with the building facade, the lateral moving plate moves along with it to seal the lateral gap between the platform support plate and the building facade.

[0022] S6: When laying the boards and transporting materials, the moving board moves and drives the traction board to move. The traction board drives the support frame to slide on the side wall of the middle seat, and the support frame supports the boards.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. A protective structure for an unloading platform on an irregular floor, wherein, through the design of a bending component, when the output end of the first telescopic component remains stationary, the output end of the second telescopic component drives the end moving plate to move, causing the end moving plate to deflect relative to the middle moving plate, and the second coil spring to deform, causing multiple moving plates to change from a straight line arrangement to an arc arrangement until they fit against the building facade, thereby sealing the gap between the platform support plate and the building facade and preventing construction workers from falling due to stepping into a hole.

[0025] 2. A protective structure for unloading platforms on irregular floors. When it is necessary to fix the platform support plate to the floor, it is only necessary to install ground anchor bolts on the floor in advance, and fix the support steel structure and ground anchor bolts to complete the fixation of the platform support plate. This installation method is simple and quick, reducing installation time and labor costs.

[0026] 3. A protective structure for an unloading platform on an irregular floor, wherein a receiving plate is welded to the outer walls of both sides of the movable plate, and a tension spring is hung between adjacent receiving plates, which works in conjunction with a coil spring. When the end movable plate slides along the guide rod with the corresponding movable block under the drive of the electric telescopic rod, the tension of the tension spring ensures the stability between multiple movable plates, avoids relative rotation between multiple movable plates, and ensures that the movable plate can accurately fit against the building facade.

[0027] 4. A protective structure for an unloading platform on an irregular floor, wherein a winding roller is rotatably connected to both sides of the platform support plate, and a nylon protective net is wound on the winding roller. When the moving plate moves, the nylon protective net is unwound along the winding roller and laid in the gap between the platform support plate and the building facade, thereby increasing the protection range. A support frame is set at the bottom of the platform support plate. In the event of a breakage of the nylon protective net, the support frame can support the construction personnel, providing a double protection function.

[0028] 5. A protective structure for an unloading platform on an irregular floor, wherein the inner walls of the lateral support plate are fixed with slide rails, the outer walls of the slide rails are slidably connected with sliders, the bottom of the sliders are rotatably connected to lateral moving plates, and the bottom of the lateral moving plates and the top of the end moving plates are rotatably connected, which can seal the lateral gap between the platform support plate and the building facade and provide lateral protection.

[0045] Example 1:

[0046] A protective structure for unloading platforms on irregular floor surfaces, such as Figures 1 to 8As shown, a bending assembly is installed at the bottom of the platform support plate 1. The bending assembly includes a movable plate 7 and an elastic element for connecting two movable plates 7. The elastic element includes a U-shaped frame 17 and a locking block 20. The U-shaped frame 17 and the locking block 20 are respectively welded to the outer walls of both sides of the movable plate 7. A central shaft 22 is embedded and fixed in the through hole opened inside the locking block 20. Adjacent U-shaped frames 17 and central shaft 22 are rotatably connected. A coil spring 21 is installed between the outer circumference of the central shaft 22 and the bottom outer wall of the U-shaped frame 17. Telescopic component 1 and telescopic component 2 are respectively installed at the bottom of the platform support plate 1. The output end of telescopic component 1 is fixedly connected to the movable plate 7 located in the middle through a connecting plate 16. The output ends of the two telescopic components 2 are rotatably connected to the movable plates 7 at both ends through a connecting plate 27.

[0047] When the building facade is irregularly shaped such as curved, in order to prevent gaps between the end of the platform support plate 1 and the building during unloading, which could cause construction workers to fall, and to ensure the safety of construction workers, after the platform support plate 1 is fixed to the floor and extends outside the building, when the output end of the first telescopic component remains stationary, the middle movable plate 7 does not move. At the same time, the output end of the second telescopic component drives the end movable plate 7 to move, so that the end movable plate 7 deflects relative to the middle movable plate 7 during the movement. During this process, the second coil spring 21 deforms, and the multiple movable plates 7 gradually change from a straight line arrangement in the initial stage to an arc arrangement. When the side of each movable plate 7 is in contact with the building facade, the movable plates 7 are used to seal the gap between the platform support plate 1 and the building facade, thereby preventing construction workers from falling and ensuring construction safety.

[0048] The bottom of the platform support plate 1 is welded with a pad 5, and the bottom of the pad 5 is welded with a supporting steel structure 4;

[0049] When it is necessary to fix the platform support plate 1 to the floor, the ground anchor bolts are installed on the floor in advance. After fixing the support steel structure 4 and the ground anchor bolts, the platform support plate 1 can be fixed to the floor.

[0050] The telescopic component includes a vertical plate 11 and an electric telescopic rod 15. The vertical plate 11 is fixed to the outer wall of one side of the platform support plate 1 by bolts, and the electric telescopic rod 15 is fixed to the outer wall of one side of the vertical plate 11 by bolts. The connecting plate 16 is fixed to the output end of the electric telescopic rod 15 by pins, and the connecting plate 16 and the movable plate 7 located in the middle are fixedly connected.

[0051] The telescopic component 2 includes a movable block 24 and a guide rod 26. The guide rod 26 is fixed to the inner wall of one side of the platform support plate 1 by bolts, and the movable block 24 is slidably connected to the outer wall of the guide rod 26. A rectangular block 25 is rotatably connected to the bottom of the movable block 24, and an electric telescopic rod 6 is fixed to one side of the outer wall of the rectangular block 25 by bolts. A connecting plate 27 is fixed to the output end of the electric telescopic rod 6 by pins, and the connecting plate 27 and the movable plate 7 located at the end are rotatably connected.

[0052] After the platform support plate 1 is fixed to the floor via the supporting steel structure 4 and the pad 5, the electric telescopic rod 15 is first controlled to drive the connecting plate 16 and the middle moving plate 7 to move. This is to ensure that the middle moving plate 7 is in contact with the building facade. During this process, the output end of the electric telescopic rod 16 remains stationary. Since the coil springs 21 deform unidirectionally in the circumferential direction, the connecting action of the coil springs 21 is used to make the end moving plate 7 slide along the guide rod 26 with the corresponding moving block 24 under the drive of the electric telescopic rod 15. After the middle moving plate 7 is in contact with the building facade, the output end of the electric telescopic rod 15 remains stationary, and the output end of the electric telescopic rod 16 drives the connecting plate 27 to move, so that the multiple moving plates 7 gradually change from a straight line arrangement in the initial stage to an arc arrangement until they are in contact with the building facade.

[0053] The outer walls on both sides of the movable plate 7 are welded with receiving plates 19, and the same tension spring 18 is connected between two adjacent receiving plates 19.

[0054] The tension spring 18 can be used in conjunction with the coil spring 21. The tension of the tension spring 18 ensures the stability of multiple moving plates 7 and prevents relative rotation between multiple moving plates 7 when the moving plate 7 at the end slides along the guide rod 26 with the corresponding moving block 24 under the drive of the electric telescopic rod 25.

[0055] The through holes on both sides of the platform support plate 1 are rotatably connected to the winding roller 13, and the outer circumference of the winding roller 13 is wound with a nylon protective net 14. The end of the nylon protective net 14 away from the winding roller 13 is fixedly connected to the top of multiple movable plates 7. A coil spring 12 is installed between the outer circumference of the winding roller 13 and the side wall of the platform support plate 1.

[0056] During the movement of the central movable plate 7 and the end movable plate 7, they will pull the nylon protective net 14, causing the nylon protective net 14 to be unwound along the winding roller 13, so that the nylon protective net 14 is laid in the gap between the platform support plate 1 and the building facade, thereby increasing the protection range of the nylon protective net 14 and protecting the construction personnel. The coil spring 12 ensures that the nylon protective net 14 is in a taut state when it needs to be rolled up after use.

[0057] The platform support plate 1 has a side support plate 2 welded to the top outer wall, and the inner walls on both sides of the side support plate 2 are fixed with slide rails 9 by bolts. The slide rails 9 are slidably connected to the outer wall of the slide rails 9, and the bottom of the slide rails 8 is rotatably connected to a side moving plate 3. The bottom and the top of the moving plate 7 at the end of the side moving plate 3 are rotatably connected.

[0058] To provide lateral protection for construction workers, when the middle movable plate 7 moves laterally under the drive of the electric telescopic rod 15, the end movable plate 7 causes the lateral movable plate 3 and the slider 8 to slide along the slide rail 9. When the end movable plate 7 moves to be in contact with the building facade, due to the rotatable connection between the lateral movable plate 3 and the slider 8, and the rotatable connection between the lateral movable plate 3 and the end movable plate 7, the lateral movable plate 3 will follow the end movable plate 7 to move to the building facade, thereby sealing the lateral gap between the platform support plate 1 and the building facade.

[0059] A sliding plate 23 is fixed between the inner walls of the two sides of the bottom of the platform support plate 1 by bolts. A middle seat 30 is slidably connected to the sliding groove 10 opened on the top inner wall of the sliding plate 23. A support frame 28 is slidably connected to the side wall of the middle seat 30. A traction plate 29 is rotatably connected to the bottom of the support frame 28. The traction plate 29 and the side wall of the moving plate 7 are fixedly connected.

[0060] To provide dual protection for construction workers, the support frame 28 can be used to support workers in case the nylon protective net 14 breaks, and the support frame 28 can also support the materials when laying boards between the floor and platform support plate 1 for transporting materials by trolley.

[0061] In this embodiment, ground anchor bolts are pre-installed on the floor. After fixing the supporting steel structure 4 to the ground anchor bolts, the platform support plate 1 is fixed on the floor. The electric telescopic rod 15 drives the connecting plate 16 and the middle moving plate 7 to move, keeping the middle moving plate 7 in contact with the building facade. During this process, the output end of the electric telescopic rod 16 remains stationary. Due to the unidirectional deformation of the coil springs 21 in the circumferential direction, the end moving plate 7 slides along the guide rod 26 with the corresponding moving block 24 under the drive of the electric telescopic rod 15. After the middle moving plate 7 is in contact with the building facade, the output end of the electric telescopic rod 15 remains stationary, and the output end of the electric telescopic rod 16 drives the connecting plate 27 to move, so that the multiple moving plates 7 gradually change from a straight line arrangement in the initial stage to an arc arrangement until they are in contact with the building facade. During the movement, the middle moving plate 7 and the end moving plate 7 pull the nylon protective net 14, making the nylon protective net 14 move. The nylon protective net 14 is unwound along the winding roller 13 and laid in the gap between the platform support plate 1 and the building facade. The nylon protective net 14 is used to increase the protection range and protect the construction personnel. When the middle moving plate 7 moves laterally under the drive of the electric telescopic rod 15, the end moving plate 7 drives the lateral moving plate 3 and the slider 8 to slide along the slide rail 9. When the end moving plate 7 moves to be in contact with the building facade, due to the rotational connection between the lateral moving plate 3 and the slider 8, the lateral moving plate 3 and the end moving plate 7 will move together with the end moving plate 7 to the building facade. The lateral moving plate 3 is used to seal the lateral gap between the platform support plate 1 and the building facade. When it is necessary to lay the board between the floor and the platform support plate 1 for material transportation, the moving plate 7 moves and drives the traction plate 29 to move. The traction plate 29 drives the support frame 28 to slide on the side wall of the middle seat 30. The support frame 28 can support the board.

[0062] Example 2:

[0063] A construction method for a protective structure for an unloading platform on an irregular floor includes the following steps:

[0064] S1: Install ground anchor bolts on the floor, fix the supporting steel structure 4 to the ground anchor bolts, and complete the fixing of the platform support plate 1;

[0065] S2: After the platform support plate 1 is fixed, the electric telescopic rod 15 drives the connecting plate 16 and the middle moving plate 7 to move so that they fit against the building facade. At this time, the output end of the electric telescopic rod 16 is stationary, and the moving plate 7 at the end slides along the guide rod 26 with the corresponding moving block 24 under the drive of the electric telescopic rod 15.

[0066] S3: After the middle movable plate 7 is attached, the output end of the electric telescopic rod 15 is stationary, and the output end of the electric telescopic rod 6 drives the connecting plate 27 to move, so that the multiple movable plates 7 change from a straight line arrangement to an arc arrangement until they are attached to the building facade.

[0067] S4: When the middle and end moving plates 7 move, the nylon protective net 14 is pulled to unwind along the winding roller 13 and laid in the gap between the platform support plate 1 and the building facade to increase the protection range. The coil spring 12 is used to ensure that the nylon protective net 14 is taut when it is wound up.

[0068] S5: When the middle moving plate 7 moves laterally, the end moving plate 7 drives the lateral moving plate 3 and the slider 8 to slide along the slide 9. When the end moving plate 7 is in contact with the building facade, the lateral moving plate 3 moves accordingly to seal the lateral gap between the platform support plate 1 and the building facade.

[0069] S6: When laying the board and transporting materials, the moving plate 7 moves and drives the traction plate 29 to move. The traction plate 29 drives the support frame 28 to slide on the side wall of the intermediate seat 30. The support frame 28 supports the board.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

6. A protective structure for an unloading platform on an irregular floor as described in claim 5, characterized in that, The movable plate (7) has a receiving plate (19) welded on both outer walls, and the same tension spring (18) is connected between two adjacent receiving plates (19).

7. A construction method for a protective structure for an unloading platform on an irregular floor as described in claim 6, characterized in that, Includes the following steps: S1: Install ground anchor bolts on the floor to fix the supporting steel structure (4) to the ground anchor bolts, and complete the fixing of the platform support plate (1); S2: After the platform support plate (1) is fixed, control the electric telescopic rod two (15) to drive the connecting plate one (16) and the middle moving plate (7) to move so that they fit against the building facade. At this time, the output end of the electric telescopic rod one (6) is stationary, and the end moving plate (7) slides along the guide rod (26) with the corresponding moving block (24) under the drive of the electric telescopic rod two (15). S3: After the middle moving plate (7) is attached, the output end of the electric telescopic rod two (15) is stationary, and the output end of the electric telescopic rod one (6) drives the connecting plate two (27) to move, so that the multiple moving plates (7) change from a straight line arrangement to an arc arrangement until they are attached to the building facade; S4: When the middle and end moving plates (7) move, pull the nylon protective net (14) to unwind along the winding roller (13) and lay it in the gap between the platform support plate (1) and the building facade to increase the protection range. Use the coil spring (12) to ensure that the nylon protective net (14) is taut when it is wound up. S5: When the middle moving plate (7) moves laterally, the end moving plate (7) drives the side moving plate (3) and the slider (8) to slide along the slide (9). When the end moving plate (7) is in contact with the building facade, the side moving plate (3) moves accordingly to seal the lateral gap between the platform support plate (1) and the building facade. S6: When laying the board and transporting materials, the moving board (7) moves and drives the traction board (29) to move. The traction board (29) drives the support frame (28) to slide on the side wall of the middle seat (30). The support frame (28) supports the board.
