Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, and more specifically, it relates to a connection structure for installing tunnel fire-fighting water supply pipelines. Background Technique

[0002] In the field of tunnel engineering, fire-fighting water supply pipelines, as important infrastructure for ensuring tunnel safety, their installation quality is directly related to the effectiveness of fire emergency response and personnel safety. During the installation of traditional tunnel fire-fighting water supply pipelines, a series of technical problems are faced, especially in the installation and maintenance of pipeline connection structures, and these problems are particularly prominent.

[0003] Currently, the fire-fighting water supply pipelines in tunnels mainly use rigid steel structure materials. This material has good pressure resistance, corrosion resistance and high temperature resistance, which can ensure the stable operation of the pipeline under extreme conditions. However, the steel pipeline itself is relatively heavy, bringing great challenges to installation and maintenance work. For the convenience of maintenance and repair, the pipeline is usually fixed on the tunnel wall. Although this fixing method is simple and effective, when replacing or installing a new pipeline, the old pipeline needs to be removed first, and then the new pipeline needs to be accurately aligned and fixed, with complex operations and long time consumption.

[0004] Installing pipelines in a specific space like a tunnel has many limitations. The tunnel space is narrow, and large support equipment is difficult to enter, resulting in the inability to rely on mechanical power to efficiently complete the pipeline installation task. Therefore, the traditional method usually relies on multiple workers to manually support the pipeline and align and fix it by manually adjusting the pipeline position. This method not only has a high labor intensity, high requirements for workers' operation skills, but also has great instability, easily leading to installation errors and affecting the connection quality of the pipeline and the overall water supply smoothness.

[0005] The method of manually supporting and installing pipelines not only has low efficiency, but also has great potential safety hazards. Due to the heavy weight of the pipeline, workers are prone to fatigue during long-term operations. If they are not careful, pipeline detachment or collision accidents may occur, posing a threat to the personal safety of workers. In addition, the accumulation of errors during the installation process will also bring many inconveniences to subsequent use and maintenance, increasing the overall cost.

[0006] Therefore, in order to solve the above technical problems, this application proposes a connection structure for installing tunnel fire-fighting water supply pipelines. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a connection structure for installing tunnel fire-fighting water supply pipelines.

[0008] To achieve the above purpose, the utility model provides the following technical solution: A connection structure for installing tunnel fire-fighting water supply pipelines,

[0009] 1. It is characterized in that it includes a limit ring and a support ring. The limit ring is installed on the connecting pipe to achieve position calibration and overall support. The support ring is connected to the pipe to be connected to support and adjust it. The limit ring is connected to the support ring through a connecting frame, and a support foot is installed at the other end of the limit ring away from the support ring. After the limit ring is fixed on the connecting pipe, the support foot can abut against the wall of the connecting pipe to form a supporting force and improve stability. An adjustment box is arranged at the position of the connecting frame corresponding to the support ring, and a screw rod B is rotatably connected in the adjustment box. One end of the support ring extends into the adjustment box and is threadedly connected to the screw rod B. The connecting frame forms an operation cavity between the limit ring and the support ring.

[0010] Preferably, a screw rod A is threadedly connected to the limit ring. By rotating the screw rod A, the limit ring can adapt to water supply pipes of different sizes, facilitating fixed limit.

[0011] Preferably, a plurality of screw rods B are rotatably connected in the adjustment box. A driven gear is installed at one end of each screw rod B, and a knob is rotatably connected to the adjustment box. The knob is meshed and connected to each driven gear through a driving gear;

[0012] By driving the plurality of screw rods B to rotate simultaneously with the knob, when adjusting the pipe through the support ring, the support ring can move more stably.

[0013] Preferably, anti-slip layers are provided on the parts of the limit ring, the support foot and the screw rod A that contact the water supply pipe. The anti-slip layer can increase the friction between the overall connection structure and the water supply pipe and reduce the possibility of sliding.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] 1. In the present utility model, by sleeving the limit ring on other pipes and forming stable support through the support foot, at the same time, extending the pipe to be installed into the operation cavity from the support ring, approaching the pipe to be installed and the connecting pipe, turning the screw rod B, driving the pipe to be installed to adjust the position through the support ring, and after alignment, using tools to connect the two pipes, it is convenient to support the pipes, reduce manual operation at the same time, and improve the stability during overall installation, thus solving the problem that in the prior art, manually supporting the pipes is not only cumbersome but also prone to installation errors.

[0022] As Figures 1-4 shown, the present utility model provides a connecting structure for installing a tunnel fire fighting water supply pipeline, including a limit ring 1 and a support ring 6. The limit ring 1 is installed on the connecting pipeline for position calibration and overall support. The support ring 6 is connected to the pipeline to be connected for alignment support and adjustment. The limit ring 1 is connected to the support ring 6 through a connecting frame 2, and a support foot 4 is installed at the other end of the limit ring 1 away from the support ring 6. After the limit ring 1 is fixed on the connecting pipeline, the support foot 4 can abut against the wall of the connecting pipeline to form a supporting force and improve stability. An adjustment box 8 is provided at the position of the connecting frame 2 corresponding to the support ring 6, and a lead screw B9 is rotatably connected in the adjustment box 8. One end of the support ring 6 extends into the adjustment box 8 and is threadedly connected to the lead screw B9. The connecting frame 2 forms an operation cavity 7 between the limit ring 1 and the support ring 6;

[0023] In summary, compared with the problem in the prior art that manually supporting the pipeline is not only more cumbersome but also prone to installation errors, in the present invention, the limit ring 1 is sleeved on other pipelines fixed on the wall, that is, pipelines that are not faulty and do not need to be replaced, and stable support is formed through the support foot 4. At the same time, the pipeline to be installed extends from the support ring 6 into the operation cavity 7, and the pipeline to be installed is brought close to the connecting pipeline. The lead screw B9 is rotated, and the pipeline to be installed is driven by the support ring 6 to adjust the position. After alignment, tools are used to connect the two pipelines, realizing convenient support for the pipeline, reducing manual operation, and improving the stability during the overall installation;

[0024] It should be noted that although there are usually only several standard sizes for the fire water supply pipes used in tunnels, in order to make the connection mechanism more stable and also to adapt to pipes of more sizes, a lead screw A5 is threadedly connected to the limit ring 1. By rotating the lead screw A5, the limit ring 1 can be adapted to water supply pipes of different sizes, facilitating fixed positioning, improving the overall practicality, and also forming a relatively stable support structure in cooperation with the support feet 4;

[0025] Among them, as Figures 3-4 shown, in order to prevent a lead screw B9 from driving the support ring 6 to move, a plurality of lead screws B9 are rotatably connected in the adjustment box 8. A driven gear 13 is installed at one end of each lead screw B9. A knob 11 is rotatably connected to the adjustment box 8. The knob 11 is meshed and connected to each driven gear 13 through a driving gear 12;

[0026] By driving the plurality of lead screws B9 to rotate simultaneously with the knob 11, when adjusting the pipe through the support ring 6, the plurality of lead screws drive the support ring 6 to move, enabling the support ring 6 to move more stably;

[0027] It should be noted that anti-slip layers are provided on the parts of the limit ring 1, the support feet 4, and the lead screw A5 that come into contact with the water supply pipe. The anti-slip layer can increase the friction between the overall connection structure and the water supply pipe and reduce the possibility of sliding.

[0028] The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and as described above; however, any equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by making some modifications, decorations, and evolutions using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
