Description

Technical Field

[0001] This utility model relates to the field of pipeline support technology for underground utility tunnels, and in particular to a comprehensive support for underground utility tunnels. Background Technology

[0002] With the accelerating pace of urbanization, underground utility tunnels, as a crucial component of urban infrastructure, bear the responsibility of laying and protecting various pipelines such as electricity, communications, gas, and water supply and drainage. Their construction quality and operational efficiency directly impact the normal functioning of the city. During the construction and maintenance of underground utility tunnels, the installation, inspection, and replacement of pipelines all rely on support systems for pipe positioning and maintenance. Therefore, the structural rationality and ease of use of the support systems are key factors influencing the effectiveness of utility tunnel projects.

[0003] Currently, most common underground utility tunnel supports consist of an installation arm and a support arm fixed to the installation arm, with the pipe placed directly on top of the support arm for support. However, in actual operation, when pipes need to be installed, repositioned, moved, transported, or replaced, direct contact occurs between the pipe and the support arm. Due to the lack of a dedicated transport mechanism, sliding friction occurs between the pipe and the support arm surface during movement. This phenomenon brings several problems: on the one hand, the high frictional resistance makes the pipe movement time-consuming and labor-intensive, increasing the labor intensity of construction workers and seriously affecting construction efficiency; on the other hand, the direct friction between the pipe and the support arm causes wear on the outer surface of the pipe. For some pipes made of softer materials or with anti-corrosion coatings, this wear may damage the structural integrity or anti-corrosion performance of the pipe, shorten its service life, and even cause safety hazards.

[0004] Therefore, there is an urgent need for a comprehensive support system for underground utility tunnels that can reduce frictional resistance during pipeline movement, reduce pipeline wear, and improve transportation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a comprehensive support for underground pipe corridors, which can reduce frictional resistance during pipe movement, reduce pipe wear, improve transportation efficiency, has a simple structure, is easy to operate and use, and is highly practical.

[0006] The present invention adopts the following technical solution:

[0007] An integrated support for underground utility tunnels includes an installation arm with multiple support arms spaced apart from top to bottom. Each support arm has a receiving groove along its length on its upper part, and a rotating roller is rotatably installed in each receiving groove, wherein the rotating roller can move in and out of the receiving groove.

[0008] Preferably, the support arm is a U-shaped structure with the opening facing downwards.

[0009] Preferably, the rotating roller is hinged to the support arm on one side away from the mounting arm, and the other end is detachably connected to the support arm; wherein the rotating roller can be adjusted by rotation along the hinge point, and a groove is provided on the end of the support arm away from the mounting arm.

[0010] Preferably, the end of the roller is rotatably provided with an L-shaped connecting shaft, which is hinged to a hinge plate at the bottom of the support arm; the end of the roller away from the connecting shaft is rotatably provided with a mounting shaft, and a mounting hole is provided radially through the mounting shaft; a pin is movably passed through the support arm, and the pin is inserted into the mounting hole when the roller is in operation.

[0011] Preferably, each of the support arms is movably provided with a positioning pin that passes through the groove, and the connecting shaft is provided with a positioning hole.

[0012] Preferably, the pin is elastically mounted on the support arm by a first spring.

[0013] Preferably, the positioning pin is elastically mounted on the support arm by a second spring.

[0014] Preferably, the positioning pin is elastically mounted on the support arm by a second spring.

[0015] Preferably, a reinforcing corner plate is provided between the bottom of both sides of the receiving groove along the width direction and the inner sidewall of the support arm.

[0016] Preferably, the reinforcing corner plate is welded to the support arm.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: By rotating a roller within the upper receiving groove of the support arm, the sliding friction between the pipe and the support arm is transformed into rolling friction of the roller. This significantly reduces the resistance encountered by the pipe during movement, making pipe installation, position adjustment, and transportation operations more labor-saving and convenient. It effectively reduces the labor intensity of construction personnel, greatly shortens operation time, and improves construction and maintenance efficiency. Due to the presence of the roller, the pipe no longer directly contacts the support arm during movement; instead, displacement is achieved through the rolling of the roller, avoiding frictional wear between the pipe's outer surface and the support arm. This is particularly important for pipes made of softer materials or with anti-corrosion coatings, effectively protecting the structural integrity and anti-corrosion performance of the pipe, extending its service life, and reducing safety hazards caused by pipe wear.

[0018] Furthermore, the design of the rollers, which can be moved in and out of the receiving groove, allows the support frame to be flexibly adjusted according to actual needs. When it is necessary to fix the pipeline, the rollers can be moved out of the receiving groove, allowing the pipeline to be placed directly on the support arm, ensuring the stability of the support; when it is necessary to move the pipeline, the rollers can be moved back into the receiving groove to perform their rolling conveying function. This design allows the support frame to meet the stable support requirements of the pipeline while also adapting to pipeline movement and conveying scenarios, improving the adaptability of the support frame in different construction and operation and maintenance stages.

[0020] Figure 2 This is a schematic diagram of the structure after the state of the rotating roller is adjusted according to an embodiment of this application;

[0021] Figure 3 This is a front view of the roller in an embodiment of this application. Detailed Implementation

[0022] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0023] like Figures 1 to 3 As shown, the integrated support for underground utility tunnels according to this utility model includes an installation arm 1, which can be a channel steel structure. The installation arm 1 is vertically installed on the wall of the underground utility tunnel and can be fixed by expansion bolts or pre-embedded. Both of these methods are commonly used in the prior art. Multiple support arms 2 are spaced apart from top to bottom on the installation arm 1, and the support arms 2 are arranged perpendicular to the installation arm 1. Each support arm 2 is detachably connected to the installation arm 1 by bolts. Each support arm 2 has a jacking opening along its length on its upper part. Each receiving groove 3 contains a rotating roller 4, the top of which protrudes from the receiving groove 3 to contact the pipeline, facilitating pipeline transport. This invention, by rotating the roller 4 within the receiving groove 3 on the upper part of the support arm 2, transforms the sliding friction between the pipeline and the support arm 2 into rolling friction of the roller 4, significantly reducing the resistance encountered during pipeline movement. This makes pipeline installation, position adjustment, and transport operations more labor-saving and convenient, effectively reducing the labor intensity of construction personnel, greatly shortening operation time, and improving construction and maintenance efficiency.

[0024] In this embodiment, the rotating roller 4 can be moved in and out of the receiving groove 3, allowing the support to be flexibly adjusted according to actual needs. When it is necessary to fix the pipeline, the rotating roller 4 can be moved out of the receiving groove 3, allowing the pipeline to be placed directly on the support arm 2, ensuring the stability of the support; when it is necessary to move the pipeline, the rotating roller 4 can be moved back into the receiving groove 3 to perform its rolling conveying function. This design allows the support to meet the stable support requirements of the pipeline and adapt to the scenario of pipeline movement and conveying, improving the adaptability of the support in different construction and maintenance stages. In addition, in this embodiment, reinforcing angle plates 5 are provided between the bottom of both sides of the receiving groove 3 along the width direction and the inner sidewall of the support arm 2. The reinforcing angle plates 5 are welded to the support arm 2 to ensure the structural strength of the entire support arm 2.

[0025] Furthermore, in this embodiment, the support arm 2 is a U-shaped channel steel structure with its opening facing downwards. The rotating roller 4 is hinged to the support arm 2 on the side away from the mounting arm 1, and detachably connected to the support arm 2 on the other end; the rotating roller 4 can be adjusted by rotating along the hinge point, and a groove 6 is provided on the end of the support arm 2 away from the mounting arm 1. This arrangement facilitates controlling the rotating roller 4 to rotate along the hinge point after the pipe installation is completed, so that the rotating roller 4 is vertically positioned on one side of the support arm 2, such as... Figure 2 As shown, this design can limit the movement of the pipeline. Specifically, an L-shaped connecting shaft 7 is rotatably mounted at the end of the roller 4, and the connecting shaft 7 is hinged to a hinge plate located at the bottom of the support arm 2. An installation shaft 8 is rotatably mounted at the end of the roller 4 away from the connecting shaft 7. An installation hole 9 is radially provided on the installation shaft 8, and a pin 10 is movably mounted on the support arm 2, extending along the width of the support arm 2. When the roller 4 is in operation, the pin 10 passes through the installation hole 9 to position it, ensuring the stability of the roller 4 in a horizontal state. In addition, a positioning pin 11 is movably mounted on the support arm 2, passing through a groove 6, and a positioning hole 12 is provided on the connecting shaft 7. After the pipeline is installed, the pin 10 is removed, and the roller 4 is controlled to rotate along the hinge point, making it vertical and located on one side of the support arm 2. At this time, the connecting shaft 7 is located in the groove 6, and the positioning pin 11 passes through the positioning hole 12 to complete the positioning of the roller 4, ensuring the stability of the roller 4 when limiting the pipeline.

[0026] Preferably, in this embodiment, the pin 10 is elastically mounted on the support arm 2 by the first spring 13, and the positioning pin 11 is elastically mounted on the support arm 2 by the second spring 14; under the action of the first spring 13 and the second spring 14, the stability of the pin 10 and the positioning pin 11 can be guaranteed, reducing the risk of falling and being lost.

[0027] In use, this utility model first installs the mounting arm 1 on the wall of the pipe gallery according to construction requirements, and then installs the support arm 2. The spacing between the upper and lower support arms 2 is adjusted according to the diameter of the pipe to be laid. At this time, the rotating roller 4 is located in the receiving groove 3. After the pipe is installed, the positioning pin 10 on the mounting shaft 8 is released, and the rotating roller 4 is controlled to rotate along the hinge point. The rotating roller 4 is moved out from the bottom of the support arm 2, and the positioning pin 11 is pulled out so that the connecting shaft 7 is located in the groove 6. At this time, the rotating roller 4 is arranged vertically on one side of the support arm 2. Then, the positioning pin 11 is inserted into the positioning hole 12 to complete the positioning of the rotating roller 4 and prevent the rotating roller 4 from flipping along the hinge point. The entire support structure is simple and easy to operate. The displacement is achieved by the rolling of the rotating roller 4, avoiding friction and wear between the outer surface of the pipe and the support arm 2. It effectively protects the structural integrity and anti-corrosion performance of the pipe, extends the service life of the pipe, and reduces safety hazards caused by pipe wear.
