Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology, and in particular to an auxiliary device for pipeline installation in integrated utility tunnels. Background Technology

[0002] Integrated utility tunnels are underground or above-ground structures designed to integrate various public utility pipelines in a city, improving the efficiency, maintainability, and manageability of urban infrastructure. By concentrating different types of pipelines in a single space, such as water supply lines, drainage lines, natural gas pipelines, power cables, and fiber optic communication cables, they achieve comprehensive management. This integrated structure helps reduce clutter in underground spaces, simplifies pipeline maintenance and management, improves the cleanliness of urban roads and surface spaces, and reduces the cost and time required for pipeline maintenance and repair. The construction of integrated utility tunnel systems makes urban infrastructure more efficient and sustainable, providing a more flexible and sustainable infrastructure solution for future urban development.

[0003] The existing integrated utility tunnel requires two workers to lift the pipes onto the tunnel supports during installation, then align the ends of the pipes before connecting them. This method, which relies on manual alignment, is too cumbersome. Furthermore, the tunnel contains numerous pipes, requiring manual adjustment of their positions, which takes a considerable amount of time and labor. This not only increases the intensity of manual labor but also fails to meet the construction and installation schedule requirements. Summary of the Invention

[0004] To address the technical problems mentioned in the background section, this invention provides an auxiliary device for the installation of integrated utility tunnels. Its advantages are: the mobile vehicle, lifting components, and clamping components can reduce the physical labor of workers, especially during hoisting and moving. This not only reduces the workload of workers but also lowers the potential risk of injury caused by physical labor. Furthermore, compared with manual installation, the automated process can greatly improve installation efficiency and save a significant amount of time.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: An auxiliary device for pipeline installation in a utility tunnel includes a mobile vehicle with a connecting plate fixedly connected to the top of the mobile vehicle. An electric slide rail is provided on one side of the connecting plate, and a lifting assembly is provided on one side of the electric slide rail. The lifting assembly includes a rotating roller, a connecting steel rope sleeved on the outer wall of the rotating roller, a pulley below the rotating roller, and the connecting steel rope located on the outer wall of the pulley. The connecting steel rope is used to drive the pipe to rise. The clamping assembly includes a fixed jaw, one end of which is connected to a shaft inside the pulley. The fixed jaw is composed of two clamping frames rotatably connected and is used to clamp the pipe.

[0006] The above technical solutions—lifting components and clamping components—can reduce the physical labor of workers, especially during hoisting and movement. This not only reduces the workload of workers but also lowers the potential risk of injury caused by physical labor.

[0007] The present invention is further configured such that a movable block is slidably connected to the front side of the connecting plate, and the movable block is fixedly connected to the fixed rod.

[0008] The above technical solution involves a fixed claw gripping the pipe, which is then easily moved by the mobile vehicle. During the movement, the pipe is positioned close to the ground, which helps to lower the overall center of gravity and improve stability. Once the pipe reaches the installation location, the moving block on the connecting plate lifts it up to the corresponding pipe rack support position, facilitating pipe placement.

[0009] The invention is further configured such that a block is slidably connected inside the electric slide rail, a placement frame is fixedly connected to the bottom of the block, and a motor is provided on one side of the placement frame.

[0010] With the above technical solutions, the electric slide rail can drive the block to move when it is running.

[0011] The invention is further configured such that the rotating roller is fixedly connected to the output end of the motor, the two ends of the rotating roller are rotatably connected to the placement frame, the two ends of the connecting steel rope are fixedly connected to the placement frame and the rotating roller respectively, and a fixing component is provided on the side of the fixing rod away from the electric slide rail.

[0012] Through the above technical solution, the motor can drive the rotating roller to rotate, and the rotation of the rotating roller will cause the pipe inside the fixed claw below the connecting steel rope to rise. Compared with the manual handling in the existing technology, it reduces the labor intensity of workers, reduces the potential personal injury risk such as pipe falling, and greatly improves the installation efficiency.

[0013] The present invention is further configured such that the fixing component includes an L-shaped plate, two clamping plates are provided on the inner side of the L-shaped plate, a first threaded rod is threadedly connected to the inside of the L-shaped plate, a movable plate is rotatably connected to one end of the first threaded rod, the movable plate is rotatably connected to one of the clamping plates, the other clamping plate is rotatably connected to the fixing rod, and both ends of the two clamping plates are provided with protrusions.

[0014] Through the above technical solution: when the moving block rises to the corresponding pipe rack support position, one of the clamping plates contacts the pipe rack support. When one of the clamping plates is in close contact with it, the first threaded rod is rotated to drive the other clamping plate to be in close contact with the pipe rack support. Furthermore, the clamping plates in the fixing assembly are rotatably connected, so when the pipe rack support is triangular or square, the clamping plate will also be in close contact with it, improving its applicability. The protrusions on the clamping plate provide additional friction, which can effectively prevent the fixing rod from shifting and improve the stability of the installation.

[0015] The invention is further configured such that a limiting groove is formed inside the L-shaped plate, and the movable plate is slidably connected to the limiting groove.

[0016] Through the above technical solutions, the limiting groove can ensure that the moving plate always moves along its internal trajectory.

[0017] The invention is further configured such that a sliding plate is fixedly connected to the side of the electric slide rail near the fixed rod, a sliding groove is provided inside the fixed rod, the sliding plate is slidably connected to the sliding groove, a second threaded rod is threadedly connected inside the fixed rod, and a pressure pad is fixedly connected to the bottom of the second threaded rod, the pressure pad being located above the sliding plate.

[0018] Through the above technical solution: when the pipe rack support to be installed is moved, rotating the second threaded rod increases the clamping force of the pressure pad on the slide plate, increases the friction, and keeps the slide plate in the position after the movement.

[0019] The invention is further configured such that each clamping end of the fixing claw is provided with an adjustment component, which is used for fine adjustment during pipe docking.

[0020] The present invention is further configured such that the adjustment assembly includes multiple sets, each set of adjustment assembly includes an arc plate, the arc plate is fixedly connected to the clamping end of the fixed claw, a limit groove is formed on one side of the arc plate, an adjustment plate is fixedly connected to one side of the connecting rod, and two sliders are slidably connected inside the connecting rod.

[0021] The invention is further configured such that each set of adjustment components includes two drive rods, which are fixedly connected to corresponding sliders respectively. One end of the connecting rod is rotatably connected to a disc via a damping bearing. The disc has two arc-shaped grooves inside, and the two drive rods are slidably connected to the corresponding arc-shaped grooves respectively. Resistance grooves are provided on both sides of the limiting groove, and friction plates are provided inside the two resistance grooves respectively. The sliders are slidably connected to the corresponding resistance grooves respectively.

[0022] The above technical solution involves rotating the disc to move the drive rod to the inner end of the arc groove, causing the slider to disengage from the friction plate. At this point, fine adjustments can be made using the adjusting plate, allowing the pipe to be manually moved to the ideal position. After fine adjustments, the disc is rotated in the opposite direction to move the drive rod to the outer end, causing the slider to contact the friction plate. This ensures that the adjusting plate remains fixed. Finally, the flange holes of the two pipes are fixed with bolts to ensure the accuracy and stability of the pipe connection process.

[0023] The beneficial effects of this invention are as follows: 1. The present invention reduces the physical labor of workers by setting up lifting and clamping components, especially during hoisting and moving. This not only reduces the labor burden of workers, but also reduces the potential risk of injury caused by physical labor. Moreover, compared with manual installation, the automated process can greatly improve the efficiency of installation and save a lot of time.

[0024] 2. The present invention, through the setting of the fixing component, can be connected and fixed with the pipe rack support, which can effectively prevent the fixing rod from shifting and improve the stability of the installation.

[0025] 3. The motor of the present invention can drive the rotating roller to rotate, and the rotation of the rotating roller will cause the pipe inside the fixing claw below the connecting steel rope to rise. Compared with the manual handling in the prior art, it reduces the labor intensity of workers, reduces the potential personal injury risk such as pipe falling, and greatly improves the installation efficiency.

[0026] 4. By adjusting the components, the position of the pipe can be finely adjusted to ensure accurate alignment of the two flange holes, thereby guaranteeing the connection and installation quality of the pipe. After fine-tuning, the adjusting plate will be fixed by friction to ensure that the pipe remains stable during the docking process, reducing unnecessary movement or shaking and further improving the stability of the docking.

[0027] 5. The clamping plate of the present invention is rotatably connected to the moving plate and the fixing rod. Therefore, when the pipe rack support is triangular or square, the clamping plate will also be in close contact with it, which improves its applicability. The groove on the clamping plate provides additional friction, which can effectively prevent the fixing rod from shifting and improve the stability of the installation. Attached Figure Description

[0030] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] Reference Figures 1-9 An auxiliary device for pipeline installation in a utility tunnel includes a mobile vehicle 1, a connecting plate 2 fixedly connected to the top of the mobile vehicle 1, an electric slide rail 9 on one side of the connecting plate 2, and a lifting assembly on one side of the electric slide rail 9. The lifting assembly includes a rotating roller 15, a connecting steel rope 17 is sleeved on the outer wall of the rotating roller 15, a pulley 16 is provided below the rotating roller 15, the connecting steel rope 17 is located on the outer wall of the pulley 16, and the connecting steel rope 17 is used to drive the pipe to rise. The clamping assembly includes a fixed claw 18, one end of which is connected to a shaft inside the pulley 16. The fixed claw 18 is composed of two clamping frames rotatably connected and is used to clamp the pipe.

[0033] Reference Figures 4-5 A movable block 3 is slidably connected to the front side of the connecting plate 2. The movable block 3 is fixedly connected to the fixed rod 4. A block is slidably connected inside the electric slide rail 9. A placement frame 13 is fixedly connected to the bottom of the block. A motor 14 is provided on one side of the placement frame 13. A rotating roller 15 is fixedly connected to the output end of the motor 14. Both ends of the rotating roller 15 are rotatably connected to the placement frame 13. Both ends of the connecting steel rope 17 are fixedly connected to the placement frame 13 and the rotating roller 15 respectively. A fixing component is provided on the side of the fixed rod 4 away from the electric slide rail 9.

[0034] When a transport pipeline (such as a communication optical cable) needs to be installed, the pipeline is clamped by the fixing claw 18. Two mobile carts 1 form a group, and each uses the fixing claw 18 to lift one pipeline. During the movement, the pipeline is positioned close to the ground, which helps to lower the overall center of gravity and improve stability. After moving to the corresponding position, another pipeline is moved to the position where it needs to be installed, corresponding to the end of the previous pipeline. Then, the moving block 3 on the moving connecting plate 2 (which can be an electric track and slider as in the prior art) drives the pipeline to rise. When it rises to the position of the corresponding pipe rack support, the motor 14 can be started. The motor 14 drives the rotating roller 15 to rotate. The rotation of the rotating roller 15 drives the pipeline inside the fixing claw 18 below the connecting steel rope 17 to rise. Compared with the manual handling in the prior art, this reduces the labor intensity of the workers, reduces the potential personal injury risk such as pipeline falling, and greatly improves the installation efficiency.

[0035] Reference Figures 2-3 The fixing component includes an L-shaped plate 5, with two clamping plates 6 on the inner side of the L-shaped plate 5. A first threaded rod 8 is threadedly connected to the inside of the L-shaped plate 5. A movable plate 7 is rotatably connected to one end of the first threaded rod 8. The movable plate 7 is rotatably connected to one of the clamping plates 6, and the other clamping plate 6 is rotatably connected to the fixing rod 4. Both ends of the two clamping plates 6 are provided with protrusions. A limit groove is opened inside the L-shaped plate 5, and the movable plate 7 is slidably connected to the limit groove.

[0036] By setting up the fixing components, it can be docked and fixed with the pipe rack support. Specifically, when the moving block 3 rises to the upper row of pipe rack supports of the pipe to be installed, one of the clamping plates 6 contacts the pipe rack support (which can be square or triangular). When one of the clamping plates 6 is in close contact with it, the first threaded rod 8 is rotated. The first threaded rod 8 drives the other clamping plate 6 to be in close contact with the pipe rack support. Because the clamping plate 6 is rotatably connected, when the pipe rack support is triangular, the clamping plate 6 will also be in close contact with it, which improves its applicability. The protrusions on the clamping plate 6 provide additional friction, which can effectively prevent the fixing rod 4 from shifting and improve the stability of the installation.

[0037] Reference Figures 2-4 The electric slide rail 9 is fixedly connected to the side of the fixed rod 4 with a slide plate 12. The fixed rod 4 has a slide groove inside, and the slide plate 12 is slidably connected to the slide groove. The fixed rod 4 has a second threaded rod 11 inside, and a pressure pad 10 is fixedly connected to the bottom of the second threaded rod 11. The pressure pad 10 is located above the slide plate 12.

[0038] After the clamping plate 6 is in close contact with the pipe rack support, the pressure pad 10 is moved away from the top of the slide plate 12 by rotating the second threaded rod 11, which pushes the electric slide rail 9 forward. When the pipe rack support to be installed is moved, the pressure pad 10 increases the clamping force on the slide plate 12 when the second threaded rod 11 is rotated, which increases the friction and keeps the slide plate 12 in the position after the movement.

[0039] Reference Figures 6-8 Each clamping end of the fixed claw 18 is equipped with an adjustment component. The adjustment component is used for fine adjustment during pipe connection. The adjustment component includes multiple sets. Each set of adjustment components includes an arc plate 19, which is fixedly connected to the clamping end of the fixed claw 18. A limit groove is opened on one side of the arc plate 19. An adjustment plate 20 is fixedly connected to one side of the connecting rod 21. Two sliders 22 are slidably connected inside the connecting rod 21. Each set of adjustment components also includes two drive rods 24, which are fixedly connected to the corresponding sliders 22. One end of the connecting rod 21 is rotatably connected to a disc 23 through a damping bearing. Two arc grooves are opened inside the disc 23. The two drive rods 24 are slidably connected to the corresponding arc grooves. Resistance grooves are opened on both sides of the limit groove. Friction plates 25 are provided inside the two resistance grooves. The sliders 22 are slidably connected to the corresponding resistance grooves.

[0040] By adjusting the settings of the components, the clamped pipe can be fine-tuned to ensure that the flange holes correspond. Specifically, after the fixing claw 18 clamps the pipe and rises to the height of the pipe rack support, the pipe needs to be connected. During connection, the position of the two flange holes is first fine-tuned. Rotating the disc 23 rotates the drive rod 24 to the inner end of the arc groove, so that the two sliders 22 move into the inside of the connecting rod 21, so that the sliders 22 do not contact the friction plate 25. At this time, the adjusting plate 20 can be rotated, and the pipe is manually fine-tuned. After the adjustment is completed, the disc 23 is rotated in the opposite direction. The disc 23 is connected to the connecting rod 21 through a damping bearing. The damping bearing can provide a certain damping. Under no external force, the disc 23 will not rotate, so that the drive rod 24 rotates from the inner end to the outer end of the arc groove, so that the sliders 22 contact the friction plate 25. The friction generated between them will keep the adjusting plate 20 stationary, ensuring the accuracy and stability of the pipe connection process. At this time, the flange holes of the two pipes are fixed and installed with bolts.

[0041] Working principle: During installation, the pipe is first clamped by the fixing claw 18. Due to the weight of the pipe itself, the fixing claw 18 generates a certain vertical pressure between itself and the pipe. The greater this pressure, the greater the clamping force of the fixing claw 18 on the pipe. After clamping, two moving carts 1 form a group, each lifting one pipe using the fixing claw 18. During movement, the pipe is positioned close to the ground, which helps lower the overall center of gravity and improve stability. After moving to the corresponding position, the other pipe is moved to the desired installation location, aligning its ends with the previous pipe, and then connected. The movable block 3 on plate 2 drives the pipe to rise. When the fixed rod 4 rises to the upper row of pipe rack supports of the pipe to be installed, one of the clamping plates 6 contacts the pipe rack support. When one of the clamping plates 6 is in close contact with the pipe rack support, the first threaded rod 8 is rotated. The first threaded rod 8 drives the other clamping plate 6 to be in close contact with the pipe rack support, fixing the fixed rod 4 to the pipe rack support and preventing displacement. After the clamping plate 6 is in close contact with the pipe rack support, the second threaded rod 11 is rotated to move the pressure pad 10 away from the top of the slide plate 12, pushing the electric slide rail 9 forward. When the pipe moves to the pipe rack support to be installed... When the slide plate 12 is in the correct position, rotating the second threaded rod 11 increases the clamping force of the pressure pad 10 on the slide plate 12, increasing friction and keeping the slide plate 12 in the moved position. Then, the motor 14 is started, driving the rotating roller 15 to rotate. The rotation of the rotating roller 15 causes the pipe inside the fixing claw 18 below the connecting steel rope 17 to rise. After rising, the pipe needs to be connected. During connection, first, fine adjustments are made according to the positions of the two flange holes. Rotating the disc 23 rotates the drive rod 24 to the inner end of the arc groove, moving the two sliders 22 inside the connecting rod 21 so that the sliders 22 do not contact the friction plate 25. The adjusting plate 20 can be rotated, and the pipeline can be manually fine-tuned. After adjustment, the disc 23 is rotated in the opposite direction, causing the drive rod 24 to rotate from the inner end to the outer end of the arc groove, so that the slider 22 contacts the friction plate 25. The friction generated between them will keep the adjusting plate 20 stationary. At this time, the flange holes of the two pipelines are fixed with bolts. Then, the electric slide rail 9 on a set of moving carts 1 moves the block, and then the motor 14 is started to place the pipeline on the pipe rack support. The pipeline is then gently lifted by hand to separate it from the fixing claw 18. Then the moving cart 1 is moved to install and connect the next set of pipelines. The above operation process ensures the efficiency and safety of the pipeline installation process. If the top row of pipelines needs to be installed, the fixing rod 4 is raised to abut against the top wall, and then the pipeline is raised for installation.

[0042] First, the pipe is held by the fixing claw 18, utilizing the pipe's own weight to generate vertical pressure, enhancing the clamping force of the fixing claw 18 and ensuring the stability of the pipe during movement. Second, by moving the pipe closer to the ground, the overall center of gravity is effectively lowered, improving stability and safety during movement. During the docking process, precise fine-tuning and bolt fixing ensure the accuracy and firmness of the pipe installation. Then, driven by the electric slide rail 9 and motor 14, the pipe is raised and lowered, reducing labor costs and improving work efficiency. Overall, this operating procedure ensures safety while improving the efficiency and accuracy of pipe installation, providing crucial guarantees for the smooth progress and quality assurance of the project.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
