Description

Technical Field

[0001] This invention relates to the field of pipe gallery construction technology, specifically to a double-rope pipe laying structure and method for long-distance pipe galleries. Background Technology

[0002] In power plants, chemical plants, and other projects, a large portion of the pipelines are laid out in pipe racks. Pipe racks are generally elevated steel structures. The characteristics of prefabricated pipe racks are high steel frame density and small spacing between pipe rack layers. Once the pipe racks are installed, pipe installation is quite difficult.

[0003] Chinese utility model CN218560954U discloses a pipe-passing construction structure for a pipe gallery, which includes a pipe gallery, at least one pipe-passing point in the pipe gallery, and a pipe-moving platform at the pipe-passing point; multiple pipe-passing devices are sequentially installed on the pipe gallery along the pipe-passing direction, and each pipe-passing device forms a pipe-passing moving platform; a winch is installed at the end of the pipe-passing moving platform, and a fixed pulley is installed on the crossbeam of the pipe gallery at the end of the pipe-passing moving platform, and the wire rope of the winch is connected to the pipe to be passed through the fixed pulley.

[0004] While the aforementioned device can enable pipe routing through utility tunnels, some problems still exist during its implementation:

[0005] 1. Due to the long pipe length and the lack of a limiting device at the pipe end, the pipe end is in a free state when the winch pulls the pipe, which may cause it to swing during the movement and come into contact with the steel columns of the pipe rack, thereby damaging the pipe.

[0006] 2. After the first pipe enters the pipe gallery through the pipe passage, a second pipe needs to be welded after the first pipe, and so on. When the distance of the pipe passage is too long, the length of the welded pipe will be very long, which will make the pipe heavy and difficult for the winch to pull. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a double-rope pipe laying structure and method in a long-distance pipe gallery, which is used to limit the pipe during the pipe laying process and ensure the stability of the pipe during the transmission process.

[0008] The technical solution adopted by this invention to solve its technical problem is a double-rope pipe laying structure in a long-distance pipe gallery, including a pipe gallery, a pipe-passing channel provided on the pipe gallery, an operating platform provided at the starting end of the pipe-passing channel, multiple conveying devices for pipe rolling provided at the bottom of the pipe-passing channel, the multiple conveying devices arranged along the length direction of the pipe-passing channel, a pipe provided above the conveying devices, two sets of first clamps provided at the starting end of the pipe, the two sets of first clamps arranged along the circumference of the pipe, and a second clamp provided at the ending end of the pipe.

[0009] The first buckle includes a connecting plate, on which multiple rope clamping devices are provided. A snap-fit ​​plate is provided below the connecting plate. A first snap-fit ​​groove for clamping the pipe wall is formed between the snap-fit ​​plate and the connecting plate. A first locking bolt for locking the pipe wall is provided on the connecting plate.

[0010] The second buckle includes an installation ring, on which a pull-back rope and two hooks are provided. The two hooks and the installation ring form a second locking groove for locking the pipe wall. The installation ring is provided with a second locking bolt. The end of the pipe channel is provided with two sets of first pulleys. Each first pulley is wound with a steel rope. One end of each steel rope is connected to a winch, and the other end passes through the rope locking device and is connected to the installation ring.

[0011] Furthermore, the rope clamping device includes two opposing clamping plates, with a clamping groove formed between the two clamping plates, and the top ends of the two clamping plates are connected by bolts.

[0012] Furthermore, a rubber tube is fitted onto the outside of the hook.

[0013] Furthermore, both the first locking bolt and the second locking bolt have rubber pads at their bottoms.

[0014] Furthermore, the distance between two adjacent conveying devices is less than half the length of the pipe.

[0015] Furthermore, the end of the snap-fit ​​plate is provided with a connector for opening or closing the first snap-fit ​​slot.

[0016] Furthermore, the conveying device includes a support plate, and two mounting plates are arranged opposite each other on the upper part of the support plate. A roller is arranged between the two mounting plates. The roller is rotatably connected to the mounting plates through a connecting shaft. The axis of the connecting shaft is perpendicular to the axis of the pipe. The roller is provided with a mounting groove for placing the pipe.

[0017] Furthermore, a second pulley is provided below the first pulley, the winch is located below the operating platform, and the steel rope passes around the first pulley and the second pulley in sequence and is fixedly connected to the winch.

[0018] Furthermore, the first pulley is positioned at a height higher than the pipe.

[0019] The double-rope pipe laying method, which employs a double-rope pipe laying structure within a long-distance pipe gallery, includes the following steps:

[0020] S1: Pipe in place; move the pipe into the operating platform and place the pipe to be threaded on the conveyor device;

[0021] S2: Install the first clip; snap the first slot of the first clip into the pipe wall of the pipe to be penetrated, place the two first clips on both sides of the top of the pipe to be penetrated, the distance between the two first clips is 1 / 3 of the arc length of the diameter of the pipe to be penetrated, and the distance from the two first clips to the top of the pipe to be penetrated is equal, and tighten the first locking bolt.

[0022] S3: Install the second clip; snap the second clip into the second slot of the second clip onto the pipe wall of the pipe to be pierced, place the second clip at the top of the pipe to be pierced, and tighten the second locking bolt;

[0023] S4: Threading rope through the pipe to be threaded; Install two sets of first pulleys at the end of the pipe threading channel, and wind steel ropes on the two first pulleys respectively. One end of the steel rope is connected to the winch, and the other end passes through the rope clamping device and is connected to the mounting ring of the second buckle; and install a pull-back rope on the mounting ring.

[0024] S5: The pipe to be threaded is in place; start the winch, and under the traction of the two steel ropes and by pulling the pullback rope to ensure the stability of the pipe to be threaded, drive the pipe to be threaded to move along the conveying device and transport the pipe to the installation position.

[0025] S6: Disconnect the first and second clips from the pipe to be threaded; turn off the winch, and the construction personnel at the installation position loosen the first and second locking bolts and release the rope clamping device so that the steel rope can move in the rope clamping device, and remove the first and second clips from the pipe to be threaded.

[0026] S7: First and second latches return to their original positions; activate the winch reverse switch, pull the pullback rope to pull the first and second latches back to the operating platform, and the process is complete, then preparations for the next pipe transfer can begin.

[0027] The beneficial effects of this invention are:

[0028] Two first clamps are installed at the beginning of the pipeline, each connected to a steel cable. A winch pulls the two cables, creating two fulcrums on the pipeline, ensuring stability during movement and preventing overturning. A second clamp is installed at the end of the pipeline, with a pull-back rope attached. During operation, the pull-back rope is pulled, and the combined action of the steel cables and the pull-back rope prevents the pipeline from swaying during movement. After the pipeline is delivered to its destination, the first and second clamps are removed, and the pull-back rope is used to return them to their initial positions, thus completing the laying of the second pipeline.

Detailed Implementation

[0038] 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.

[0039] like Figures 1-6 As shown, this invention discloses a double-rope pipe laying structure for long-distance pipe corridors, comprising a pipe corridor 1, a pipe-passing channel 2 provided on the pipe corridor 1, and an operating platform 3 provided at the starting end of the pipe-passing channel 2. The invention is characterized in that: multiple conveying devices 5 for rolling pipes 4 are provided at the bottom of the pipe-passing channel 2, the multiple conveying devices 5 are arranged along the length of the pipe-passing channel 2, and a pipe 4 is provided above the conveying devices 5. Two sets of first clamps 6 are provided at the starting end of the pipe 4, the two sets of first clamps 6 are arranged circumferentially along the pipe 4, and a second clamp 7 is provided at the ending end of the pipe 4.

[0040] The first buckle 6 includes a connecting plate 601, on which a plurality of rope clamping devices 602 are provided. A clamping plate 603 is provided below the connecting plate 601. A first clamping groove 604 for clamping the pipe wall is formed between the clamping plate 603 and the mounting plate 502. A first locking bolt 605 for locking the pipe wall is provided on the connecting plate 601.

[0041] The second buckle 7 includes a mounting ring 701, on which a pull-back rope 702 and two hooks 703 are provided. The two hooks 703 and the mounting ring 701 form a second locking groove 704 for locking the pipe wall. The mounting ring 701 is provided with a second locking bolt 705. The end of the pipe channel 2 is provided with two sets of first pulleys 12. Each first pulley 12 is wound with a steel rope 8. One end of each steel rope 8 is connected to the winch 9, and the other end passes through the rope clamping device 602 and is connected to the mounting ring 701.

[0042] The pipe passage 2 is used to place the pipe 4. It is a square passage formed by two steel crossbeams 11 and two steel longitudinal beams. Multiple square passages form the pipe passage 2. The height of the operating platform 3 is the same as the bottom of the pipe passage 2. The operating platform 3 is set on the ground or is a suspended platform. The operating platform 3 is used to place the pipe 4, and the staff can also operate on the operating platform 3. The conveying device 5 is used to transport the pipe 4, so that the pipe 4 moves along the length of the pipe passage 2 within the pipe passage 2.

[0043] The function of the first clip 6 is to connect the steel rope 8 and the pipe 4. The rope clamping device 602 is used to fix the connecting plate 601 to the steel rope 8, preventing relative movement between the connecting plate 601 and the steel rope 8. Both the connecting plate 601 and the clamping plate 603 are steel plates and can be connected by welding. The clamping plate 603 is L-shaped, thus forming a first clamping groove 604 between the connecting plate 601 and the clamping plate 603. The width of the first clamping groove 604 is greater than the wall thickness of the pipe 4. After the pipe wall is placed in the first clamping groove 604, the first locking bolt 605 locks the pipe wall in the first clamping groove 604. It should be noted that using two first clips 6 to connect the pipe 4, and each of the two first clips 6 is connected to two steel ropes 8, can improve the stability of the pipe 4 during movement and prevent the pipe 4 from deflecting during movement.

[0044] The second clip 7 also serves to connect the steel cable 8 and the pipe 4. It works in conjunction with the first clip 6 to fix the pipe 4 between the first clip 6 and the second clip 7. The mounting ring 701 can be formed by bending a steel bar, and a hook 703 is welded to the bottom of the mounting ring 701. The connection between the hook 703 and the mounting ring 701 is arc-shaped. Two hooks 703 are provided to increase the contact area between the second clip 7 and the pipe 4, making the second clip 7 more stable on the pipe 4. The hook 703 is L-shaped, thus forming a second... The width of the second slot 704 is greater than the wall thickness of the pipe 4. After the pipe wall is placed in the second slot 704, the second locking bolt 705 is used to lock the pipe wall in the second slot 704. A pull-back rope 702 is set on the mounting ring 701. The pull-back rope 702 can be made of hemp rope or nylon rope. One end of the pull-back rope 702 is connected to the mounting ring 701, and the other end is connected to the hoisting equipment. Alternatively, the worker can hold the other end of the pull-back rope 702 to provide a balancing pull force during the movement of the pipe 4, so that the pipe 4 remains stable during the movement.

[0045] The winch 9 is set on the ground or on the pipe gallery 1. In order to reduce the difficulty of transportation, it is preferred to set the winch 9 on the ground. The output end of the winch 9 is connected to one end of two steel ropes 8. The steel ropes 8 are sleeved on the first pulley 12. The other end of the steel ropes 8 passes through the rope clamping device 602 and is connected to the mounting ring 701. In this way, the winch 9 can be used to pull the steel ropes 8 to drive the pipe 4 to move in the pipe passage 2, and finally realize the pipe passage operation of the pipe gallery 1.

[0046] Further, see Figure 4 The rope clamping device 602 includes two opposing clamping plates 606, with a clamping groove 607 formed between the two clamping plates 606. The top ends of the two clamping plates 606 are connected by bolts. The clamping plates 606 and the connecting plate 601 can be connected by integral molding or bolts. When both the clamping plates 606 and the connecting plate 601 are made of steel, they can also be welded together. The clamping groove 607 is used to place the steel rope 8. The steel rope 8 is placed in the clamping groove 607, and the top ends of the clamping plates 606 are connected using bolts. The spacing of the clamping grooves 607 is adjusted using bolts until the steel rope 8 is clamped securely.

[0047] To prevent the hook 703 from scratching the inner wall of the pipe 4, a rubber tube is further provided on the outer side of the hook 703.

[0048] To prevent the first and second bolts from scratching the outer wall of pipe 4, rubber pads are provided at the bottom of both the first locking bolt 605 and the second locking bolt 705.

[0049] To prevent the pipe 4 from slipping off the conveying device 5 as it moves on the conveying device 5; furthermore, the distance between two adjacent conveying devices 5 is less than half the length of the pipe 4.

[0050] During the process of pulling back the first latch 6, the first slot 604 may get stuck on the crossbeam 11. Further details can be found in the documentation. Figure 3 The end of the snap-fit ​​plate 603 is provided with a connector 608 for opening or closing the first snap-fit ​​slot 604. The connector 608 can be made of steel wire or hemp rope; as one embodiment, the connector 608 is an arc-shaped steel plate, with one end of the connector 608 hinged to the connecting plate 601 and the other end bolted to the snap-fit ​​plate 603, or one end of the connector 608 hinged to the snap-fit ​​plate 603 and the other end bolted to the connecting plate 601; when the pipe 4 is being conveyed, the first snap-fit ​​slot 604 is opened, and when the first snap-fit ​​6 is pulled back, the first snap-fit ​​slot 604 is closed.

[0051] Further, see Figure 7 The conveying device 5 includes a support plate 501, and two mounting plates 502 are arranged opposite each other above the support plate 501. A roller 503 is arranged between the two mounting plates 502. The roller 503 is rotatably connected to the mounting plates 502 through a connecting shaft 504. The axis of the connecting shaft 504 is perpendicular to the axis of the pipe 4. The roller 503 is provided with a mounting groove 505 for placing the pipe 4.

[0052] The support plate 501 can be made of steel or wood. The mounting plate 502 can be connected to the support plate 501 by bolts. When both the support plate 501 and the mounting plate 502 are made of steel, they can also be connected by welding. The roller 503 can be made of wood or steel and has a circular cross-section. The connecting shaft 504 can be connected to the two mounting plates 502 by bearings and is integrally formed with the roller 503. Similarly, the connecting shaft 504 can also be fixedly connected to the mounting plate 502 and rotatably connected to the roller 503 by bearings. The connecting shaft 504 and the roller 503 are coaxial, which can ensure the stability of the pipe 4 rolling on the roller 503. The mounting groove 505 is V-shaped or U-shaped. This design allows the two sides of the mounting groove 505 to limit the pipe 4 placed on the roller 503, ensuring the stability of the pipe 4 during the conveying process.

[0053] To better control the movement of pipe 4, see further... Figure 1A second pulley 10 is provided below the first pulley 12, and the winch 9 is located below the operating platform 3. The steel rope 8 passes around the first pulley 12 and the second pulley 10 in sequence and is fixedly connected to the winch 9. The winch 9 is positioned below the operating platform 3, allowing for better communication between the operator controlling the winch 9 and the operator on the operating platform 3. Once the first latch 6 and the second latch 7 are connected to the pipe 4, the operator on the operating platform 3 can signal the operator controlling the winch 9 to start it in the forward direction. When the pipe 4 is in place, the operator on the operating platform 3 can signal the operator controlling the winch 9 to stop it. Similarly, after removing the first latch 6 and the second latch 7 from the pipe 4, the operator on the operating platform 3 can signal the operator controlling the winch 9 to start it in the reverse direction, moving the pull-back rope 702 backward until the first latch 6 and the second latch 7 are pulled back onto the operating platform 3.

[0054] To further reduce the pressure of pipe 4 on conveying device 5, see also... Figure 1 The first pulley 12 is positioned higher than the pipe 4. This causes the steel rope 8 between the first pulley 12 and the pipe 4 to be inclined, and the tension of the steel rope 8 provided by the winch 9 will generate an upward component force, reducing the pressure of the pipe 4 on the conveying device 5 and extending the service life of the conveying device 5.

[0058] S3: Install the second clip 7; clip the second slot 704 of the second clip 7 onto the wall of the pipe 4 to be penetrated, place the second clip 7 at the top of the pipe 4 to be penetrated, and tighten the second locking bolt 705;

[0059] S4: Thread the rope through the pipe 4 to be threaded; install two sets of first pulleys 12 at the end of the pipe channel 2, and wind steel ropes 8 on the two first pulleys 12 respectively.
