Description

Technical Field

[0001] This utility model relates to the field of suspended construction technology, specifically a device for installing railings on floating bridges. Background Technology

[0002] The railings of a floating bridge are an important component for protecting the safety of pedestrians and vehicles. Generally, the railings of a floating bridge are installed at the outermost edge of the bridge deck, with the installation position facing the water. They require suspended or elevated supports for assistance, and construction workers stand on the suspended or elevated work platform to complete the installation work.

[0003] In the existing technology, the installation of floating bridge railings mainly relies on the erection of temporary scaffolding, which poses safety hazards such as personnel falling and falling objects, and the erection cost is high. The use of traditional aerial work platforms is easily limited by the terrain under the bridge, making it impossible to operate stably in deep valleys or on water, and the cost is also high. The installation methods of railings vary for different floating bridge structures, and traditional installation devices cannot be flexibly adjusted, requiring frequent changes of auxiliary tools, which delays the construction period. Therefore, this utility model provides a device for the installation of floating bridge railings. Utility Model Content

[0032] Please refer to the attached document. Figures 1-4 This application illustrates a device for installing a floating bridge railing, which provides a working platform for construction workers during the installation process. Specifically, it includes: a main trolley 1, a working trolley 3, steel strands 5, and an auxiliary frame 4.

[0033] like Figures 1-3 As shown, a cantilever section 1a is provided on one side of the main trolley 1. The cantilever section 1a is used to install the work trolley 3. Specifically, the work trolley 3 is suspended below the cantilever section 1a by steel strand 5.

[0034] like Figure 1 , Figure 2 In the usage state shown, the main trolley 1 moves to the edge of the floating bridge, so that the cantilever part 1a of the main trolley 1 is suspended above the water surface. At this time, the working trolley 3 is suspended above the water surface by the steel strand 5, thus providing a working platform for the construction personnel (the position on the working trolley 3 is the working platform). During the installation operation, the main trolley 1 can move along the edge of the floating bridge to provide a movable platform for installing the railings on the edge of the floating bridge.

[0035] like Figure 3 As shown, when in ground walking mode, an auxiliary frame 4 is installed between the main trolley 1 and the work trolley 3 to fix the main trolley 1 and the work trolley 3 into an integrated structure, which facilitates the overall movement of the main trolley 1 and the work trolley 3 on the ground.

[0036] This utility model, through the design of a main trolley 1 and a working trolley 3, with the working trolley 3 suspended from the cantilevered part 1a of the main trolley 1 by steel strand 5, provides a working platform for construction personnel by placing the main trolley 1 near the edge of the floating bridge and the working trolley 3 suspended above the water surface. During the installation process, the main trolley 1 can move along the edge of the floating bridge, providing a movable platform for installing railings on the edge of the floating bridge. Furthermore, both the main trolley 1 and the working trolley 3 can be moved when walking on the ground. The main trolley 1 and the working trolley 3 are fixed into an integrated structure by an auxiliary frame 4, facilitating the overall movement of the main trolley 1 and the working trolley 3 on the ground.

[0037] When arranging the device for installing a floating bridge railing according to this utility model, it will be as follows: Figure 3 The integrated structure shown is moved to the riverbank. The work platform 3 is temporarily lifted manually or with the help of a support frame. The work platform 3 is then moved above the river surface (the work platform 3 is suspended in the air, and is temporarily pulled by an auxiliary rope to maintain its stability). Then the auxiliary frame 4 is removed, and the work platform 3 is slowly lowered until the steel strand 5 is under tension. The work platform 3 is then suspended by the steel strand 5.

[0038] In one embodiment, a detachable ladder 6 is also designed to facilitate construction workers getting on and off the work platform 3.

[0039] The top of the detachable ladder 6 is equipped with a hook, which is hung at the cantilever part 1a of the main trolley 1. Personnel can go up and down the work trolley 3 via the detachable ladder 6.

[0040] In one embodiment, the main trolley 1 includes: a base frame 101, a first column 102, a top frame 104, a railing 105, and an arc-shaped handrail 106.

[0041] The bottom of the base frame 101 is fixedly equipped with first traveling wheels 103. The base frame 101 has a rectangular structure. Four sets of first traveling wheels 103 are provided. The first traveling wheels 103 have a braking function. The selection of first traveling wheels 103 with a braking function ensures stability of the main trolley 1 during actual use, preventing the main trolley 1 from shaking and affecting the construction personnel on the work trolley 3. The bottom end of the first upright column 102 is fixedly connected to the top edge of the base frame 101. Multiple sets of first upright columns 102 are provided, such as... Figure 2As shown, the first column 102 is provided with six sets, and the top frame 104 is fixedly connected to the top of the first column 102. The top of the top frame 104 is fixedly installed with a railing 105. The railing 105 is a two-sided railing structure. Multiple horizontal braces are fixedly connected between the first columns 102 at the end away from the cantilever 1a to form a ladder structure, so that construction workers can climb the top frame 104. One side of the top frame 104 extends outward to form the cantilever 1a. The railing 105 extends above the cantilever 1a, and the railing 105 is fixedly connected to the end of the cantilever 1a with an arc-shaped handrail 106. The arc-shaped handrail 106 is used for workers to hold on when climbing the detachable straight ladder 6.

[0042] Both the base frame 101 and the top frame 104 are formed by welding together several horizontally and vertically distributed skeletons to form a support frame, and anti-slip plates are fixedly installed on the top of the support frame.

[0043] In one embodiment, in order to increase the stability of the connection between the first column 102 and the base frame 101, a second diagonal brace 108 is fixedly connected between the first column 102 and the base frame 101.

[0044] In one embodiment, in order to increase the stability and structural strength between the first column 102 and the cantilever 1a, a first diagonal brace 107 is fixedly connected between the first column 102 and the cantilever 1a.

[0045] In one embodiment, a counterweight 2 is provided on the base frame 101. The counterweight 2 is fixedly installed in a placeable / detachable manner to increase the weight of the main trolley 1 and make it more stable.

[0046] In one embodiment, the work trolley 3 includes: a platform 301, a frame 302 fixedly installed on the top of the platform 301, and a second traveling wheel 303 fixedly installed on the bottom of the platform 301.

[0047] The second traveling wheel 303 enables the work trolley 3 to support itself on the ground and move, such as Figure 3 As shown, the main trolley 1 and the work trolley 3 are a whole, but they are still independently supported on the ground, so that they can move stably on the ground.

[0048] Specifically, the enclosure 302 includes: several main frames 3021 distributed on the edge of the platform 301, with enclosure 3022 fixedly connected between the main frames 3021, and short frames 3023 fixedly connected between the enclosure 3022 and the support of the platform 301. The short frames 3023, the main frames 3021 and the enclosure 3022 constitute an enclosure structure, which can prevent construction personnel from falling off the work trolley 3.

[0049] In one embodiment, the auxiliary frame 4 includes: a rod 401, both ends of which are fixedly connected to a clip 402, and the side of the clip 402 is threaded with a locking screw 403.

[0050] The clamp 402 is a horizontal U-shaped structure that can be clamped onto the frame of the main trolley 1 / work trolley 3. Then, the locking screw 403 is tightened to fix the clamp 402 to the main trolley 1 / work trolley 3.
