Description

Technical Field

[0001] The utility model relates to the technical field of Bailey racks, in particular to a Bailey rack for underground pipelines in municipal engineering. Background Art

[0002] Municipal engineering encompasses the construction and maintenance of urban infrastructure, including roads, bridges, and water supply and drainage systems. Underground pipeline Bailey systems play a key role in this effort, providing temporary support and protection for various underground pipelines, such as water, drainage, gas, and electricity, during construction or maintenance. This ensures accurate and safe pipeline laying, maintains the smooth progress and subsequent operation of municipal engineering projects, and safeguards the effective functioning of cities and the stable and orderly lives of residents.

[0003] Traditional Bailey frames for underground pipelines in municipal engineering projects primarily consist of Bailey plates, connecting pins, and supporting components. The Bailey plates are the core unit, comprising upper and lower chords, vertical bars, and diagonal bars, forming a stable frame structure. Connecting pins connect the Bailey plates longitudinally, allowing the Bailey frame to be adjusted in length. Support components, including transverse and longitudinal braces, enhance the overall stability and load-bearing capacity of the Bailey frame. These components work together to create a reliable support platform for underground pipelines.

[0004] From a structural perspective, the external supports of traditional Bailey racks for underground pipelines in municipal projects are difficult to store. The Bailey panels are large and fixed in shape, and the connection nodes are mostly rigid, lacking flexible folding or disassembly designs. Support components are often tightly connected to the Bailey panels and have complex structures, making them difficult to quickly disassemble. This results in a large space requirement during storage, making transportation inconvenient and increasing transportation costs. Storage also requires a large area, hindering efficient resource management and reuse. This also increases construction preparation time, reduces construction efficiency, and increases overall project costs. Utility Model Content

[0008] Furthermore, the fixing assembly includes a connecting piece, which is fixedly connected to the upper surface of each Bailey frame body.

[0009] Furthermore, the side wall of the rotating plate is fixedly connected to the side plate, and the side wall of the side plate is slidably connected to the slider.

[0010] Furthermore, both sides of the slider are fixedly connected with side platforms, and the side walls of the side platforms are fixedly connected with a first rotating shaft.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-Figure 2 The utility model provides an embodiment: a Bailey rack for underground pipelines in municipal engineering, comprising a top plate 1, a bottom plate 2 is provided at the bottom of the top plate 1, a storage assembly is provided on the top of the bottom plate 2, a Bailey rack body 9 is provided between the top plates 1, and a fixing assembly is provided on the top of the Bailey rack body 9, and the fixing assembly is used to fix the Bailey rack body 9;

[0026] The storage assembly includes a turntable 3, and multiple turntables 3 are fixedly connected to the upper surface of the bottom plate 2. Each turntable 3 is rotatably connected to a turn plate 4. The top of the turn plate 4 is rotatably connected to the bottom of the top plate 1. The right side wall of the turn plate 4 is fixedly connected to a card table 5. The bottom of the top plate 1 is slidably connected to a card plate 6. A spring 7 is provided between the card plate 6 and the top plate 1. One end of the spring 7 is fixedly connected to the inside of the top plate 1, and the other end of the spring 7 is fixedly connected to the inside of the card plate 6. The bottom of the card plate 6 is fixedly connected to a card shaft 8, and the card shaft 8 is slidably connected to the inside of the card table 5.

[0027] Specifically, when encountering a situation where the outer body bracket of the Bailey frame body 9 needs to be stored and sorted, the operator applies an upward force to push the card plate 6. After the card plate 6 is subjected to the upward external force, it will produce an upward displacement relative to the top plate 1. In this process, the card plate 6 will compress the spring 7 connected to it. At the same time, the card shaft 8 at the bottom of the card plate 6 will closely follow the moving trajectory of the card plate 6 and move upward synchronously, and will slide out of the rotating plate 4 along the preset sliding path. In this way, the limit state originally formed by the card shaft 8 on the card table 5 is released. With the release of the limit, the rotating plate 4 can rotate freely inside the turntable 3. During the rotation process, the angle of the rotating plate 4 changes relative to the top plate 1, thereby driving the bottom plate 2 to move, and finally making The bottom plate 2 and the top plate 1 are folded and in a parallel state, and the storage operation is successfully completed. This Bailey rack with a convenient folding function has significant advantages. In the transportation link, it can greatly save the space occupied by the transport vehicle. Compared with the traditional Bailey rack, it can significantly increase the number of Bailey racks in a single transport under the same transportation conditions, effectively reducing transportation costs and improving transportation efficiency. Moreover, in the storage stage, the space occupied by the folded Bailey rack is greatly reduced. Whether it is in the limited temporary storage area at the construction site or in a warehouse with relatively fixed space, it can be stored more easily, effectively alleviating the troubles caused by the tight space on the site, significantly improving the utilization efficiency of the site, and is conducive to the material management and overall layout planning of the construction site.

[0028] Reference Figure 3 and Figure 4The fixing assembly includes a connecting member 10, which is fixedly connected to the upper surface of each Bailey frame body 9, the side wall of the rotating plate 4 is fixedly connected to the side plate 11, and the side wall of the side plate 11 is slidably connected to the slider 12, and both sides of the slider 12 are fixedly connected to the side platform 13, the side wall of the side platform 13 is fixedly connected to the rotating shaft 14, the outer wall of the rotating shaft 14 is rotatably connected to the rotating frame 15, and the rotating frame 15 is internally rotatably connected to the rotating shaft 2 16, the side wall of the rotating frame 15 is fixedly connected to the fixed shaft 21, and the fixed shaft 21 is slidably connected to the inside of the connecting member 10, one end of the rotating shaft 2 16 is fixedly connected to the side wall of the slider 12, the side wall of the slider 12 is fixedly connected to the fixed block 17, and the bottom of the fixed block 17 is fixedly connected to the sliding shaft 18, the side wall of the side plate 11 is fixedly connected to the fixed block 20, the bottom of the fixed block 17 is fixedly connected to the sliding shaft 18, the sliding shaft 18 is slidably connected to the inside of the fixed block 20, and the outer wall of the sliding shaft 18 is provided with a spring 2 19.

[0029] Specifically, when faced with a scenario where the Bailey frame body 9 and the top plate 1 need to be disassembled and assembled, the construction worker manually presses the slider 12. After the slider 12 is acted upon by the pressing force, it begins to slide downward along a specific track on the side wall of the side plate 11. This displacement change of the slider 12 will further drive multiple side platforms 13 on both sides to move synchronously at the same time. During the movement of the side platform 13, the rotating shaft 14 of its side wall will be caused to move synchronously with the movement of the side platform 13. Once the position of the rotating shaft 14 changes, the rotating frame 15 outside it will start to rotate and gradually change its own inclination angle during the rotation process. At the same time, the rotating frame 15 will also move under the coordinated action of the rotating shaft 2 16 and its own outer wall. During this series of rotations, the fixed shaft 21 at the bottom of the rotating frame 15 will undergo relative displacement and slide along a predetermined path inside the connecting member 10. When the above actions are completed, the Bailey frame body 9 can be easily disassembled and assembled. This convenient disassembly and assembly feature is extremely important in areas with complex pipelines or emergency repair projects. It enables construction workers to quickly disassemble the Bailey frame body 9 in such special environments and quickly reinstall it after completing related operations, greatly improving the overall efficiency of the construction and effectively shortening the project cycle, thereby providing a strong guarantee for the smooth progress and on-time delivery of the entire project and reducing various risks and losses that may be caused by construction delays.

[0030] Working principle: When the outer body bracket of the Bailey frame 9 needs to be stored, push the card plate 6 upward. After being subjected to force, the card plate 6 moves relative to the top plate 1 and compresses the spring 7. At this time, the card shaft 8 at the bottom of the card plate 6 will move synchronously with the card plate 6 and slide out from the inside of the turntable 4, thereby releasing the limit state of the card platform 5, and further enabling the turntable 4 to rotate inside the turntable 3 relative to the top plate 1 to fold the bottom plate 2 and the top plate 1 parallel to each other to achieve storage. The conveniently foldable Bailey frame can save a lot of space during transportation. Compared with traditional Bailey frames, it can increase the number of single shipments and reduce transportation costs. The folded frame 15 is convenient for storage and can be easily disassembled and assembled at a construction site or in a warehouse, which effectively solves the problem of space shortage and improves the efficiency of site utilization.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
