Description

Technical Field

[0001] This utility model relates to the field of bridge painting technology, and in particular to a simple mobile painting platform for steel bridge decks. Background Technology

[0002] Steel structure bridge decks are widely used not only for connecting riverbanks but also for land-based applications, serving as elevated roads and greatly facilitating traffic flow. However, steel structures are susceptible to corrosion and rust due to constant exposure to air. Therefore, bridge painting is a crucial maintenance procedure, as paint effectively mitigates corrosion and extends the bridge's lifespan.

[0003] Bridge painting involves spraying paint on three surfaces of the bridge: the underside, two sides, and the crash barriers and railings. However, current methods rely on manual spraying, typically requiring scaffolding erected up to the height of the bridge's underside. This scaffolding can only cover a limited area at a time, and re-erecting scaffolding is necessary to move to a new location, resulting in significant time consumption and low efficiency. Utility Model Content

[0004] To improve the efficiency of bridge painting, this application provides a simple mobile painting platform for steel bridge decks.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A simple mobile painting platform for steel bridge decks includes an upper platform, which comprises a first frame formed by horizontal and vertical bars, wherein the horizontal bars are aligned with the length direction of the bridge and the vertical bars are perpendicular to the length direction of the bridge, and the upper platform is positioned above the bridge deck; a lower platform, which comprises a second frame, and is positioned at the bottom of the bridge; and a connecting rod, which is positioned on the side of the bridge and is fixedly connected to the first and second frames.

[0007] By employing the aforementioned device, the upper platform is located above and in contact with the bridge deck, while the lower platform is located at the bottom of the bridge and at a certain distance from it. A connecting rod is welded between the first and second frames, connecting the upper and lower platforms. During construction, workers can stand on the lower platform to perform painting operations on the bottom of the bridge, significantly improving work efficiency and shortening the construction period.

[0008] Preferably, the first frame has multiple lifting lugs on the longitudinal bars on opposite sides, and the multiple lifting lugs are fixedly connected to the upper surface of the longitudinal bars.

[0009] By employing the aforementioned device, the lifting lugs can serve as suspension points. During construction, the entire device can be lifted onto the steel bridge deck using a crane, facilitating fixation and suspension. Simultaneously, the lifting lugs also provide additional connection points, allowing the platform to be moved across the bridge deck by pushing or pulling it when necessary to move the entire work platform.

[0010] Preferably, a movable component is fixedly connected to the first frame, and the movable component drives the entire platform to move along the length of the bridge.

[0011] Preferably, the movable component includes a plurality of pulleys, which are symmetrically arranged on the longitudinal bars on opposite sides of the first frame. The pulleys are fixedly connected to the bottom of the longitudinal bars and in contact with the bridge surface.

[0012] By employing the aforementioned device, the movable component allows the entire work platform to move flexibly on the bridge according to construction needs, enabling continuous operation and a smoother construction process. It allows for rapid movement from one work point to another, further improving construction efficiency. Furthermore, the symmetrically arranged pulleys ensure the platform's balance during movement, reducing the risk of the work platform slipping off the bridge surface due to misalignment and enhancing safety.

[0013] Preferably, a first reinforcing member is provided between the connecting rod and the first frame to improve the stability of the structure.

[0014] By employing the aforementioned device, the first reinforcing diagonal brace is positioned between the connecting rod and the first frame, which significantly improves the connection strength between the connecting rod and the first frame, thereby enhancing the stability of the entire structure and improving its durability.

[0015] Preferably, the second frame is provided with a plurality of support rods, which are arranged in an alternating manner and are fixedly connected to the second frame.

[0016] Preferably, a support net is provided inside the second frame, and the support net is fixedly connected to the second frame and the support rod, and the support net is used for walking.

[0017] By employing the aforementioned device, multiple support rods are arranged in an interlaced manner, providing stronger support and ensuring the stability and load-bearing capacity of the second frame. The support net and support rods form a flat and stable walking platform, allowing construction workers to walk safely and perform various construction operations, thus providing a safe working environment for them.

[0018] Preferably, a second reinforcing member is provided between the connecting rod and the second frame to increase the stability of the structure and to attach a safety rope.

[0019] By employing the aforementioned device, the use of the second reinforcing member can improve the connection strength between the connecting rod and the second frame, thereby enhancing the stability and deformation resistance of the entire structure. It can also increase the structure's load-bearing capacity, enabling the lower platform to withstand greater loads. Simultaneously, the second reinforcing member can also serve as a safety rope attachment point for securing safety ropes or other safety equipment, improving the safety of workers.

[0020] This application has the following beneficial effects:

[0021] 1. In this application, the upper platform is located above and in contact with the bridge deck, while the lower platform is located at the bottom of the bridge and at a certain distance from the bottom. A connecting rod is welded between the first and second frames, connecting the upper and lower platforms. During construction, workers can stand on the lower platform to perform painting operations on the bottom of the bridge, which can significantly improve work efficiency and shorten the construction period.

[0022] 2. In this application, the movable component allows the entire working platform to move flexibly on the bridge according to construction needs, enabling continuous operation, smoothing the construction process, and allowing for rapid movement from one work point to another, further improving construction efficiency. Furthermore, the symmetrically arranged pulleys ensure the platform's balance during movement, reducing the risk of the working platform sliding off the bridge surface due to offset, thus improving safety.

[0027] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0028] A simple mobile painting platform for steel bridge decks, such as Figure 1-2As shown, the platform includes an upper platform 1, a lower platform 2, and connecting rods 3. The upper platform 1 is a rectangular first frame 11 formed by welding two horizontal bars 111 and two vertical bars 112 together. The horizontal bars 111 are aligned with the length direction of the bridge, while the vertical bars 112 are perpendicular to the length direction of the bridge. The lower platform 2 includes a rectangular second frame 21. The first frame 11 is located above the bridge deck, the second frame 21 is located at the bottom of the bridge, and the connecting rods are located on the sides of the bridge. The connecting rods are welded to both the first frame 11 and the second frame 21 to ensure the stability of the entire platform.

[0029] like Figure 1-2 As shown, in order to realize the function of platform movement, a moving component 13 is provided on the first frame 11, so that the entire platform can move easily along the length of the bridge. Specifically, the moving component 13 includes four pulleys 131, which are arranged in pairs and symmetrically welded to the bottom of the longitudinal bars 112 on opposite sides of the first frame 11. The pulleys 131 are in contact with the bridge deck, making the movement of the entire platform smoother.

[0030] like Figure 1-2 As shown, to facilitate the hoisting of the work platform, six lifting lugs 12 are provided on the first frame 11. These six lifting lugs 12 are arranged in pairs and symmetrically welded to the upper surface of the longitudinal bars 112 on opposite sides of the first frame 11. The lifting lugs 12 can serve as suspension points, allowing the entire work platform to be hoisted onto the steel bridge deck using a crane during construction. When the work platform needs to be moved, the lifting lugs 12 can serve as connection points, allowing the work platform to be moved on the bridge deck by pushing or pulling, thereby improving construction efficiency.

[0031] like Figure 1-2 As shown, in order to improve the stability of the working platform structure, a first reinforcing member 14 is added between the connecting rod and the first frame 11. The first reinforcing member 14 is obliquely welded between the connecting rod and the longitudinal rod 112. The first reinforcing member 14, the connecting rod, and the longitudinal rod 112 form a triangular structure, which effectively increases the stability of the entire structure and improves the durability of the structure.

[0032] In addition, a second reinforcing member 24 is provided between the connecting rod and the second frame 21 to further enhance the stability of the work platform and effectively increase the load-bearing capacity of the lower platform 2, enabling the lower platform 2 to withstand greater loads. At the same time, the second reinforcing member 24 can serve as a hanging point for safety ropes to fix safety ropes or other safety equipment, ensuring the safety of construction personnel and reducing the risk of operation.

[0033] like Figure 1-2As shown, multiple interlocking support rods 22 are welded inside the second frame 21 to enhance the load-bearing capacity of the lower platform 2. Simultaneously, a support net 23 is laid inside the second frame 21, and the support net 23 is tightly welded to the second frame 21 and the support rods 22, providing construction personnel with a safe and stable walking and working platform on which they can safely walk and perform various construction operations. In this embodiment, the support net 23 is made of steel mesh.

[0034] Working principle: Construction workers use a crane connected to lifting lugs 12 to hoist the entire work platform to the construction position, so that the first frame 11 is located on the bridge deck and the second frame 21 is located at the bottom of the bridge. During painting operations, workers stand on the lower platform 2 to spray paint the bottom of the bridge. When it is necessary to move to the next work area, the workers on the bridge deck only need to push or pull the first frame 11 to move the entire work platform along the length of the bridge, thereby achieving continuous painting operations, making the construction process smoother, quickly moving from one work point to the next, effectively improving construction efficiency and shortening the construction cycle.
