Abstract
Description
Technical Field
[0001] This invention relates to the field of pipeline transportation technology, and in particular to a pipeline installation device and its usage method in long-distance narrow tunnels. Background Technology
[0002] When natural gas pipelines are installed inside tunnels, in order to ensure the safety of pipeline operation in the later stages, the design requires that the tunnel be filled with water after the pipeline installation is completed. Therefore, anti-buoyancy blocks need to be installed on the natural gas pipelines in the early stages to prevent the pipelines from being damaged by buoyancy over a long period of time.
[0003] The dedicated tunnel for natural gas pipelines across rivers is narrow and long. Only one 800mm diameter natural gas pipeline (12m long, 12t weight) is installed inside the tunnel, and anti-buoyancy blocks (300kg each, 200mm thick) need to be installed on top. After the installation is completed, the tunnel needs to be filled with water. Because the tunnel is uneven, the conventional method of transporting and placing the pipeline by trolley is not only inefficient but also labor-intensive for workers. Therefore, it is necessary to design a pipeline installation device and its usage method for long-distance narrow tunnels. Summary of the Invention

[0037] Reference Figure 1-8 A pipeline installation device for long-distance narrow tunnels includes an anti-floating block 4, a pipeline body 25 and a support 26. The support 26 is fixedly installed at the bottom of the pipeline body 25, and the anti-floating block 4 is placed above the pipeline body 25. It also includes two parallel track bodies 1 in the tunnel. A drive base 2 is slidably installed on the top of the track body 1. A gantry mechanism is set between the tops of the two drive bases 2. Lifting ropes 8 are fixedly installed on both sides of the top of the gantry mechanism.
[0038] The gantry mechanism includes two support columns 3, with jacks 28 fixedly installed at the bottom of each support column 3. The two jacks 28 are fixedly installed at the top center of the drive base 2. Connecting columns 6 are fixedly installed at the top of each support column 3, and a top frame 7 is fixedly installed between the tops of the two connecting columns 6. Two lifting ropes 8 are fixedly installed on both sides of the bottom of the top frame 7. It makes full use of the track left by the tunnel boring machine during tunnel excavation, reducing construction costs. The drive base 2 is used to drive the overall transportation of pipes, supports and anti-buoyancy blocks 4. The modular assembly method saves labor costs and can realize the transportation, positioning and adjustment of related accessories of pipes in long and narrow tunnels. The transportation efficiency is high and the cost is saved.
[0039] The bottom of the lifting rope 8 is provided with a hooking mechanism. The top center of the anti-floating block 4 is fixedly installed with a lifting ring 9. The lifting ring 9 is hooked to the bottom of the hooking mechanism. The top two ends of the drive base 2 are fixedly installed with batteries 27 for powering the drive base 2. The bottom of both ends of the gantry mechanism is installed with a lifting mechanism. The bottom of both sides of the bracket 26 is fixedly installed with snap rings 30 that are compatible with the lifting mechanism.
[0040] The lifting mechanism includes a lifting rod (29) and a lifting hook (31) fixedly installed at the bottom of the lifting rod (29). The lifting hook (31) is engaged with a retaining ring (30). The lifting rod (29) is fixedly installed on the support column (3) by a flange.
[0041] The attachment mechanism includes a hook 16, a support block 15 fixedly installed on the top of the hook 16, and the top of the support block 15 fixedly connected to the bottom of the lifting rope 8. A support ring 14 is fitted on the bottom of the lifting rope 8, and a hanging ring 17 is fixedly installed on one side of the bottom of the support ring 14. A fixing rope 19 is fixedly installed on the end of the hook 16 away from the support block 15, and a hook lock 18 is fixedly installed on the end of the fixing rope 19 away from the hook 16. The hook lock 18 and the hanging ring 17 are mutually hooked and matched. The anti-floating block 4 is hoisted onto the pipeline by attaching the hook 16 to the lifting ring 9. Since the anti-floating block 4 covers the entire pipeline, the project is large. Therefore, this hoisting method is very convenient. After the hook 16 is attached to the lifting ring 9, the hook lock 18 is attached to the hanging ring 17 to achieve stable fixation of the lifting ring 9 and improve the safety during lifting.
[0042] Limiting plates 5 are fixedly installed at the top of the two adjacent sides of the two support columns 3. The bottom of the limiting plate 5 is provided with an inclined slot, and the slot surface is set to fit the top of the anti-floating block 4. When the anti-floating block 4 is lifted to the limiting plate 5, the anti-floating block 4 will be locked in the slot. The slot fixes the anti-floating block 4 at the front and back, thereby improving the stability and safety of the anti-floating block 4 during transportation.
[0043] The bottom of the limiting plate 5 is set as an inclined surface on the side near the anti-floating block 4. The bottom of both ends of the slot is provided with an installation groove, and a rotating roller 12 is rotatably installed between the top and bottom of the installation groove. During the process of the anti-floating block 4 entering the slot, the rotating roller 12 can effectively reduce the friction between the anti-floating block 4 and the slot, and improve the smoothness of the anti-floating block 4 entering the slot.
[0044] The top of the slot has a slot, and a buffer plate 11 is inserted into the slot. Several buffer springs 20 are fixedly installed between the buffer plate 11 and the slot at equal intervals. After the anti-floating block 4 enters the slot, the buffer plate 11 and the buffer springs 20 buffer the anti-floating block 4 to prevent the lifting rope 8 from breaking.
[0045] Both support columns 3 have threaded holes at the bottom of their opposite sides, and threaded rods 21 that are rotatably adapted to the threaded holes are installed in the threaded holes. Rotating handles 10 are fixedly installed at the opposite ends of the two threaded rods 21, and mounting plates 22 are rotatably installed at the adjacent ends of the two threaded rods 21.
[0046] The mounting plate 22 has a groove on the side near the anti-floating block 4 that is parallel to the track body 1. A pressure roller 24 is rotatably mounted between the two ends of the groove. The circumferential surface of the pressure roller 24 is evenly provided with protrusions 23. The pressure roller 24 presses and fixes the two ends of the anti-floating block 4, reducing the risk of the anti-floating block 4 swaying left and right. In addition, it can also make fine adjustments to the left and right of the anti-floating block 4, which is convenient for the transportation and positioning of the pipeline. Furthermore, the setting of the pressure roller 24 can also effectively reduce the resistance of the anti-floating block 4 moving up and down, making it convenient for the anti-floating block 4 to be lifted and lowered.
[0047] The top of the lifting ring 9 is provided with two hanging slots 13 on both sides. The hooks 16 are engaged in the hanging slots 13. After the hooks 16 are hung on the lifting ring 9, the hanging slots 13 lock the hooks 16 in place, which effectively improves the stability of the hanging.
[0048] A method for using a pipeline installation device in a long, narrow tunnel includes the following steps:
[0049] S1: First, use the track left over from the excavation of the tunnel to install a drive base on it. The drive rollers at the bottom of the drive base are set on the track and powered by a battery.
[0050] S2: The lifting ring is fixed by the lifting rope. After the jack is raised, the anti-floating block is hoisted onto the pipe body and then laid on the pipe body in sequence.
[0051] S3: After assembling the pipe, anti-floating block and support as a whole outside the tunnel, select two sets of this device, set them at both ends of the pipe, hook the lifting hooks on the shackles, raise the jacks again, and lift the pipe, anti-floating block and support as a whole.
[0052] S4: Then start the drive base to transport the entire pipe, anti-floating block and support into the tunnel;
[0053] S5: After transportation to the designated location, manually adjust the rotating handle to drive the threaded rod to extend and retract, thereby realizing the retraction of the mounting plates on both sides of the anti-floating block, and adjusting the left and right deviation of the pipe, anti-floating block and support as a whole.
[0054] S6: Finally, lower the jack to lower the pipe, anti-float block and support as a whole to complete the operation.
