Description

Technical Field

[0001] The invention relates to the technical field of pipeline laying, in particular to a fire-fighting pipeline laying device. Background Art

[0002] Offshore platforms refer to large engineering structures used for marine resource development and marine scientific research. They belong to the marine engineering equipment industry and are one of the important strategic industries. They are also key facilities in many fields such as global energy extraction, economic development, technological innovation, and energy security. Due to their special working environment and high risks, offshore platforms need to lay fire-fighting pipelines to ensure the safety of the platform.

[0003] However, the height of an offshore platform (such as a semi-submersible) will rise and fall with the tide and water level changes, which poses a great challenge to the laying of fire-fighting pipes. When laying fire-fighting pipes, it is necessary to stretch or compress the buffer pipes to adapt to the changes of the platform to ensure that the fire-fighting pipes are successfully laid. Currently, the work of stretching or contracting the buffer pipes mainly relies on manual operation through simple tools (jacks or hand winches), which is inefficient and has poor stability. In order to solve the above problems, the present invention proposes a fire-fighting pipe laying device. Summary of the invention

[0004] The purpose of the present invention is to provide a fire-fighting pipe laying device, which solves the problems of low efficiency and poor stability during the prior art fire-fighting pipe laying.

[0005] To achieve the above object, the present invention provides the following technical solution: a fire protection pipe laying device, comprising an upper pipe and a lower pipe, wherein the upper pipe and the lower pipe are respectively provided with a first flange and a third flange, and further comprising: The docking mechanism comprises a moving assembly and a cylinder, wherein a ring is installed on the outer wall of the cylinder, a second flange is installed on the side of the cylinder facing the upper pipe, openings are evenly opened on the outer wall of the cylinder, a rotating shaft is installed on the inner wall of the opening, a limiting block is rotatably installed on the outer wall of the rotating shaft, a buffer pipe is abutted on the outer wall of the limiting block, and a fourth flange is installed on the side of the buffer pipe facing the lower pipe; after the fourth flange is connected to the third flange, the moving assembly controls the stretching or compression of the buffer pipe through the cylinder and the limiting block, thereby driving the upper pipe to move and completing the laying; The mobile assembly includes a ring installed on the outer wall of the cylinder and two second clamping blocks, the upper end surfaces of the two second clamping blocks are installed with electric telescopic rods, and the output shaft of the electric telescopic rod is fixedly installed with a first clamping block; the second clamping block is clamped on the outer walls of the third flange and the fourth flange, and the first clamping block is clamped on the outer wall of the ring; when the electric telescopic rod is working, the ring is driven to move through the first clamping block.

[0006] Preferably, a plurality of fixed plates are evenly mounted on the outer wall of the cylinder, a sliding rod is symmetrically and slidably mounted on the inner wall of the fixed plate, a limiting ring and a round rod are respectively fixedly mounted on both ends of the sliding rod, a cam is rotatably mounted on the outer wall of the round rod, a round pin is abutted against the inner wall of the limiting ring, and the round pin is fixedly connected to the limiting block away from the limiting ring.

[0007] Preferably, a fixing plate is installed on the outer wall of the fourth flange, and a plurality of slots are evenly arranged on the outer wall of the fixing plate.

[0008] Preferably, a sealing ring is installed on the inner wall of the cylinder, a second sealing ring is installed on the side of the sealing ring facing the buffer pipe, and a first sealing ring is installed at the abutment between the sealing ring and the cylinder.

[0009] Preferably, a spring telescopic rod is fixedly mounted on the outer wall of the cam, and a buckle is rotatably mounted on the side of the spring telescopic rod away from the cam.

[0010] Preferably, the distance between the lower end surface of the limit block and the rotating shaft is greater than the distance between the round pin and the rotating shaft.

[0011] Preferably, the outer wall of the first clamping block is threadedly connected with a first bolt, and the outer wall of the second clamping block is threadedly connected with a second bolt.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a moving component. When the side of the upper pipeline away from the first flange does not match the height of the offshore platform, the electric telescopic rod is controlled to retract or extend. At this time, the first clamping block drives the cylinder to squeeze or stretch the buffer pipeline through the circular ring, so that the second flange is lowered or raised, thereby adjusting the position of the upper pipeline, so as to achieve rapid and stable docking and complete laying.

[0013] Second, the present invention is provided with a limit block. When the buffer pipe is stretched, the second flange pulls the cylinder, and the cylinder stretches the spring telescopic rod. The spring telescopic rod has a tendency to drive the cam to move toward one side of the fixed plate. The cam drives the round rod to move, and the round rod drives the sliding rod to move on the fixed plate. The sliding rod drives the limit ring to move, and the limit ring drives the round pin to move. The round pin drives the limit block to rotate counterclockwise around the rotating shaft. At this time, the buffer pipe will be squeezed below the limit block to increase the contact force with the second sealing ring, thereby strengthening the seal. When compressed, the spring telescopic rod contracts. At this time, the buffer pipe squeezes the limit block, and the limit block rotates counterclockwise around the rotating shaft. The limit block drives the round pin to squeeze the limit ring, and the limit ring moves to the side of the fixed disk. At this time, the limit block will not affect the buffer pipe to squeeze the second sealing ring, thereby ensuring the sealing of the pipeline after laying. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Further, such as Figure 3 As shown, the buffer pipe 15 is a bellows.

[0019] Further, such as Figure 3 and Figure 4 As shown, a plurality of fixed plates 22 are evenly mounted on the outer wall of the cylinder 4, a slide bar 21 is symmetrically slidably mounted on the inner wall of the fixed plate 22, a limit ring 23 and a round rod 20 are fixedly mounted on both ends of the slide bar 21, a cam 19 is rotatably mounted on the outer wall of the round rod 20, a round pin 26 is abutted against the inner wall of the limit ring 23, and the round pin 26 is fixedly connected to the limit block 24 away from the limit ring 23; When the buffer pipe 15 is compressed or stretched, the limiting block 24 rotates counterclockwise, so that the buffer pipe 15 squeezes the second sealing ring 30 to enhance the sealing performance.

[0020] Further, such as Figure 3 As shown, a fixing plate 13 is installed on the outer wall of the fourth flange plate 12, and a plurality of slots 14 are evenly formed on the outer wall of the fixing plate 13; The latching slot 14 enables the latching buckle 16 to be latched onto the fixing plate 13 .

[0021] Further, such as Figure 6 As shown, a sealing ring 28 is installed on the inner wall of the cylinder 4, a second sealing ring 30 is installed on the side of the sealing ring 28 facing the buffer pipe 15, and a first sealing ring 29 is installed at the abutment between the sealing ring 28 and the cylinder 4; The first sealing ring 29 maintains sealing between the sealing ring 28 and the cylinder 4 .

[0022] Further, such as Figure 5 As shown, a spring telescopic rod 17 is fixedly mounted on the outer wall of the cam 19, and a buckle 16 is rotatably mounted on the side of the spring telescopic rod 17 away from the cam 19; When the first flange 2 moves, the buckle 16 drives the spring telescopic rod 17 to extend or shorten.

[0023] Further, such as Figure 4 and Figure 5 As shown, the distance between the lower end surface of the limit block 24 and the rotating shaft 27 is greater than the distance between the round pin 26 and the rotating shaft 27; The downward movement stroke of the limit block 24 is greater than the movement stroke of the round pin 26 .

[0024] Further, such as Figure 1 and Figure 2 As shown, the outer wall of the first clamping block 5 is threadedly connected with a first bolt 6, and the outer wall of the second clamping block 9 is threadedly connected with a second bolt 8; The first clamping block 5 is clamped on the outside of the ring 18 through the first bolts 6 , and the second clamping block 9 is clamped on the outside of the third flange 11 and the fourth flange 12 through the second bolts 8 .

[0025] Working principle: Step 1: First, insert one side of the buffer pipe 15 into the cylinder 4. At this time, the buffer pipe 15 will squeeze the limit block 24, and the limit block 24 will rotate counterclockwise around the rotating shaft 27 (with Figure 4 and Figure 5 For example, the limiting block 24 drives the round pin 26 to squeeze the limiting ring 23, and the limiting ring 23 pushes the slide rod 21 to move toward the spring telescopic rod 17 until the buffer pipe 15 abuts against the second sealing ring 30 on the sealing ring 28.

[0026] Step 2: When the buffer pipe 15 abuts against the second sealing ring 30, the fourth flange 12 and the third flange 11 are connected and installed. At this time, the lower pipe 10 is in a fixed state, and then the first clamping block 5 is clamped on the outside of the ring 18. At this time, the second clamping block 9 is clamped on the outside of the fourth flange 12 and the third flange 11, and then fixed by the first bolt 6 and the second bolt 8 respectively to make it clamped, and then the second flange 3 and the first flange 2 are connected; Step 3: When the side of the upper pipeline 1 away from the first flange 2 does not match the height of the offshore platform, the electric telescopic rod 7 is controlled to retract or extend. At this time, the first clamping block 5 drives the cylinder 4 to squeeze or stretch the buffer pipeline 15 through the ring 18, so that the second flange 3 is lowered or raised, thereby adjusting the position of the upper pipeline 1. Compared with the hand winch and the jack, it has better stability and faster speed.

[0027] Step 4: After the installation is completed, remove the first clamping block 5 and the second clamping block 9, and then stretch the spring telescopic rod 17 to make the buckle 16 snap into the inside of the slot 14. At this time, the laying of the fire-fighting pipeline is completed.

[0028] Step 5: When the buffer pipe 15 is working, it will be stretched or contracted. When it is stretched, the second flange 3 pulls the cylinder 4, and the cylinder 4 stretches the spring telescopic rod 17. The spring telescopic rod 17 has a tendency to drive the cam 19 to move toward the side of the fixed plate 13. The cam 19 drives the round rod 20 to move, and the round rod 20 drives the sliding rod 21 to move on the fixed plate 22. The sliding rod 21 drives the limit ring 23 to move, and the limit ring 23 drives the round pin 26 to move. The round pin 26 drives the limit block 24 to rotate counterclockwise around the rotating shaft 27. At this time, the buffer pipe 15 will be squeezed below the limit block 24 to increase the contact force with the second sealing ring 30, thereby strengthening the seal.

[0029] Step 6: When compressed, the spring telescopic rod 17 contracts, and the buffer pipe 15 squeezes the limit block 24. The limit block 24 rotates counterclockwise around the rotating shaft 27, and the limit block 24 drives the round pin 26 to squeeze the limit ring 23. The limit ring 23 moves to the side of the fixed disk 13. At this time, the limit block 24 will not affect the buffer pipe 15 to squeeze the second sealing ring 30, thereby ensuring the sealing of the pipeline after laying.

[0030] Step 7: When the buffer pipe 15 needs to be replaced, first separate it from the lower pipe 10 and the upper pipe 1, then take the buckle 16 out of the slot 14, and then rotate it outward. The cam 19 is driven to rotate by the spring telescopic rod 17 so that the raised part of the cam 19 no longer abuts the fixed plate 22. At this time, pull out the buffer pipe 15, and the buffer pipe 15 will squeeze the limit block 24, and the limit block 24 rotates clockwise around the rotating shaft 27. Since the raised part of the cam 19 does not abut the fixed plate 22 at this time, the slide rod 21 moves away from the fixed disk 13, thereby making the limit block 24 away from the buffer pipe 15, and the buffer pipe 15 is replaced.
