Description

Technical Field

[0001] The invention belongs to the technical field related to pipeline erection, and specifically discloses a submarine pipeline erection device for marine engineering. Background Art

[0002] Marine engineering refers to new construction, reconstruction, and expansion projects that are aimed at developing, utilizing, protecting, and restoring marine resources, with the main body of the project located on the seaward side of the coastline. It is generally believed that the main contents of marine engineering can be divided into two parts: resource development technology and equipment and facility technology. Specifically, they include reclamation, offshore dam projects, artificial islands, offshore and submarine material storage facilities, cross-sea bridges, submarine tunnel projects, submarine pipelines, submarine electric (optical) cable projects, marine mineral resource exploration and development and its ancillary projects, offshore tidal power stations, wave power stations, thermoelectric power stations and other marine energy development and utilization projects, large-scale seawater aquaculture farms, artificial reef projects, salt fields, seawater desalination and other comprehensive seawater utilization projects, marine entertainment and sports, and landscape development projects. The pipeline laying device is a device for supporting and installing submarine pipelines;

[0003] Existing installation devices have poor adaptability to seabed terrain and lack fixing force in soft soil or rock layers. Embedded structures are prone to slippage or loosening due to ocean current impact or differences in soil bearing capacity. In addition, pipeline connections rely on flanges, and if misalignment occurs, the entire pipeline needs to be disassembled and reinstalled, especially in the seabed environment. The immaturity of technology in high-pressure environments will further exacerbate the risks. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the background technology, and a marine engineering submarine pipeline installation device is proposed, including an installation beam, cross frames are symmetrically arranged on the outer sides of both ends of the installation beam, and a sliding locking mechanism is arranged above the two groups of cross frames at the same end. A frame seat is provided above both ends of the installation beam, and a slide is slidably installed above the outer top of the frame seat. A fixing rod is provided above the inner top of the slide, and reverse pipe installation arc plates are provided on both sides of the outer side of the fixing rod. An arc rod is commonly provided above the outer top of the two reverse pipe installation arc plates, and a pipe pressing mechanism is provided on the inner top wall of the arc rod. A pre-buried weighting mechanism is provided inside the end of the cross frame away from the installation beam.

[0005] Preferably, the sliding locking mechanism includes a baffle slidably mounted above the outside of the frame, a sliding shell is provided at the bottom end of the baffle, a push rod is connected to the inside of the sliding shell through an elastic mechanism, moving wheels are installed below both sides of the push rod, a locking assembly is provided on the upper surface of the cross frame, and one side of the baffle is connected to the outer wall of the arc-shaped plate of the reverse frame tube.

[0006] Preferably, the elastic mechanism includes a pressure spring with one end arranged on the top wall inside the sliding housing, the lower end of the pressure spring is connected to the upper surface of the push rod, and the push rod slides inside the sliding housing.

[0007] Preferably, the positioning assembly includes arc grooves equidistantly provided on both sides of the upper surface of the horizontal frame in the horizontal direction, the arc grooves corresponding to the rolling positions of the moving wheels, and abutment bars are provided on the upper surface of the horizontal frame and between two adjacent groups of arc grooves.

[0008] Preferably, the pipe pressing mechanism includes a vertical rod fixedly mounted on the top wall inside the arc rod, an arc frame is slidably inserted at the lower outside of the vertical rod, a positioning spring is provided on the upper outside of the vertical rod, two ends of the positioning spring are respectively connected to the top wall of the arc rod and the outer surface of the arc frame, and extrusion rods are respectively provided at both ends of the arc frame, and fixed blocks are fixedly provided at both ends of the two extrusion rods, and the lower end surfaces of the four groups of fixed blocks are respectively provided with a clamping seat, the overall shape of the clamping seat is arc-shaped, and a V-shaped stop block extends from the lower outside, and the two ends of the inside of the arc rod are correspondingly connected to guide columns through a set connecting rod, and the two guide columns are respectively vertically arranged on the outer surface of the reverse frame pipe arc plate at corresponding positions.

[0009] Preferably, the embedded weighting mechanism includes a ring sleeve fixedly mounted on the cross frame and away from the inside of one end of the erection beam, an embedded rod is installed inside the ring sleeve, a screw pin is inserted through the internal thread of one side of the cross frame, one end of the screw pin extends to the inside of the ring sleeve, and the end portion is against the outer surface of the embedded rod, conical soil pieces are arranged at equal distances along the circumferential direction below the outside of the embedded rod, and a cone head is installed at the lower end of the embedded rod.

[0010] Preferably, a ring is slidably provided on the outside of the embedded rod, cables are provided on the outside of the ring at equal distances along the circumferential direction, a gravity ball is provided at the lower end of the cable, and a plurality of spikes are provided on the outer surface of the gravity ball.

[0011] Preferably, the cross frame is provided with a cross rod near the upper surface of both ends, a diverter plate is provided outside the cross rod, and paddles are extended to the rear end on both sides of the diverter plate, and multiple groups of drainage plates are provided on the outer surfaces of the diverter plate and the paddles.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The sliding positioning mechanism can cooperate with the movement of the slide when the pipe is installed. If there is an error or misalignment in the installation of the front-end pipe, the baffle on either side can be pushed to move, prompting the slide, fixed rod, and reverse pipe-racking arc plate to move. In this way, the pipe installed above can be accurately adjusted by the movement of the slide to ensure that the flanges of the two pipes are aligned and connected.

[0014] By setting up the elastic mechanism and the positioning assembly, the baffle can be instantly limited during the movement process. Therefore, no matter where the slide moves to, the moving wheel will engage with the corresponding arc groove. The pressure spring can apply pressure to the moving wheel, so that the moving wheel can avoid displacement without pushing force and affecting the rack pipe.

[0015] By setting rings, cables, gravity balls and spikes on the outside of the embedded rods, not only can the embedded rods be embedded and fixed on seabeds of different heights, but the gravity balls and spikes can also correspond to the upper surface of the seabed. The gravity balls and spikes cooperate with the embedded rods to enhance the grip of the area around the embedded rods, and can effectively deal with seabed currents.

[0016] By setting diverter plates and paddles above the two ends of the cross frame, the stability of the slide and baffle can be enhanced. When the ocean current arrives, the sliding direction of the slide and baffle drives the ocean current away from the reverse pipe rack arc plate, avoiding the slide being forced to move due to the flow rate of the ocean current. At the same time, the setting of the reverse pipe rack arc plate can change the direction of seawater flowing to the outside of the pipeline when the seawater surges, reducing the impact of the ocean current and making the pipeline more stable during installation.

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1-Figure 7 The shown device is a submarine pipeline installation device for marine engineering, including an installation beam 1, with cross frames 3 symmetrically arranged on the outside of both ends of the installation beam 1, and a sliding locking mechanism is arranged above the two groups of cross frames 3 at the same end, and a frame seat 14 is arranged above both ends of the installation beam 1, and a slide 17 is slidably installed above the outside of the frame seat 14, and a fixing rod 18 is arranged above the inside of the slide 17, and reverse pipe installation curved plates 10 are arranged on both sides of the outside of the fixing rod 18, and a curved rod 16 is commonly arranged above the outside of the two reverse pipe installation curved plates 10, and a pipe pressing mechanism is arranged on the inner top wall of the curved rod 16, and a pre-buried weighting mechanism is arranged inside the end of the cross frame 3 away from the installation beam 1.

[0028] The sliding positioning mechanism includes a baffle 15 slidably mounted on the upper part of the frame seat 14, a sliding shell 30 is provided at the bottom end of the baffle 15, and a push rod 34 is connected to the inside of the sliding shell 30 through an elastic mechanism. Moving wheels 31 are installed below both sides of the push rod 34, and a positioning component is provided on the upper surface of the cross frame 3. One side of the baffle 15 is connected to the outer wall of the reverse frame tube arc plate 10. The elastic mechanism includes a pressure spring 29 at one end provided on the top wall of the inner part of the sliding shell 30, and the lower end of the pressure spring 29 is connected to the upper surface of the push rod 34. The push rod 34 slides inside the sliding shell 30 to position the baffle. The assembly includes arc-shaped grooves 32 equidistantly provided on both sides of the upper surface of the horizontal frame 3 in the horizontal direction. The arc-shaped grooves 32 correspond to the rolling positions of the shifting wheels 31. A stop bar 33 is provided on the upper surface of the horizontal frame 3 and between two adjacent sets of arc-shaped grooves 32. When the baffle 15 is pushed, the shifting wheels 31 repeatedly roll in the multiple sets of arc-shaped grooves 32. The pressure spring 29 compresses and stores energy until the pipelines are aligned. The baffle 15 is released, and the pressure spring 29 releases the pressure, pushing the stop bar 34 downward, and the shifting wheels 31 snap into the corresponding arc-shaped grooves 32, thereby realizing rapid positioning and locking of the slide 17.

[0029] The stop bar 33 can limit the excessive lateral movement of the transfer wheel 31 at the arc groove 32.

[0030] The pipe pressing mechanism includes a vertical rod 35 fixedly mounted on the top wall of the inner part of the arc rod 16, and an arc frame 26 is slidably inserted at the bottom of the outer part of the vertical rod 35. A positioning spring 25 is provided on the upper part of the outer part of the vertical rod 35. The two ends of the positioning spring 25 are respectively connected to the top wall of the arc rod 16 and the outer surface of the arc frame 26. Extrusion rods 23 are respectively provided at both ends of the two extrusion rods 23. Fixed blocks 28 are fixed at both ends of the two extrusion rods 23. The lower end surfaces of the four groups of fixed blocks 28 are all provided with a holder 22. The overall shape of the holder 22 is arc-shaped, and a V-shaped stop block 36 extends from the bottom of the outer part. The two ends of the inner part of the arc rod 16 are connected to the guide column 24 through the provided connecting rod 27. The two guide columns 24 are respectively vertically provided on the outer surface of the reverse frame pipe arc plate 10 at the corresponding positions;

[0031] After the pipe is placed on the reverse pipe arc plate 10, the positioning spring 25 causes the arc frame 26 to descend through its own elastic force, and the clamping seat 22 elastically clamps the pipe through the V-shaped block 36;

[0032] By providing the clamping seat 22 and the squeezing rod 23 of a certain length, the contact area with the pipe is increased, thereby enhancing the stability of clamping the pipe.

[0033] The embedded weighting mechanism includes a ring sleeve 11 fixedly mounted on the cross frame 3 and away from the inside of one end of the erection beam 1, an embedded rod 8 is installed inside the ring sleeve 11, a screw pin 13 is inserted through the internal thread of one side of the cross frame 3, one end of the screw pin 13 extends to the inside of the ring sleeve 11, and the end portion is against the outer surface of the embedded rod 8, a cone soil piece 6 is provided at equal distances along the circumferential direction below the outside of the embedded rod 8, a cone head 2 is installed at the lower end of the embedded rod 8, a ring 4 is provided on the outside of the embedded rod 8 for sliding, a cable 5 is provided at equal distances along the circumferential direction on the outside of the ring 4, a gravity ball 7 is provided at the lower end of the cable 5, and a plurality of thorn heads 12 are provided on the outer surface of the gravity ball 7;

[0034] After the embedded rod 8 is inserted into the seabed, the gravity ball 7 descends due to its own weight, and the spike head 12 penetrates the bottom layer. The contact area between the cone soil piece 6 and the deep seabed is increased, which improves the pull-out resistance of the embedded rod 8. After the tensioning cable 5, a radial fixed network is formed (evenly distributed around the circumference), which improves the anti-slip performance.

[0035] When the embedded rod 8 is fixed, the outer ring 4 slides down along the rod body to the seabed surface, driving the cable 5 and the gravity ball 7 to touch the bottom. The gravity ball 7 sinks into the soft soil layer of the seabed due to its own weight, and the surface spikes 12 form multiple anchor points, thereby firmly contacting the seabed surface.

[0036] It should be noted that the length of the cable 5 can be adjusted according to the actual installation environment.

[0037] A cross bar 21 is provided on the upper surface near both ends of the cross frame 3, and a diverter plate 19 is provided outside the cross bar 21. Both sides of the diverter plate 19 extend toward the rear end with a paddle 9. The outer surfaces of the diverter plate 19 and the paddle 9 are provided with multiple groups of drainage blades 20.

[0038] The splitter plate 19 has a longitudinal wing-shaped cross section. When the ocean current hits, it divides the water flow into two streams, such as Figure 4 As shown, the guide plate 20 is separated in the middle and extends upward and downward in a curved trajectory. Therefore, when the ocean current comes into contact with it, the upper water flow flows along the upper surface of the diverter plate 19 to the rear of the top of the device, forming an upper water flow.

[0039] The lower stream flows along the lower surface of the diverter plate 19 to the rear of the bottom of the device, forming a lower stream. When the water flows through the curved diverter plate 19, the path is longer and it is forced to accelerate, prompting the ocean current to quickly bypass the main body of the device and reduce the direct impact force.

[0040] Working principle: When in use, the insertion depth of the embedded rod 8 is adjusted according to the seabed topography, the cone head 2 and the cone soil piece 6 cut into the seabed, the screw pin 13 is inserted into the ring sleeve 11 to cause the end to lock the position of the embedded rod 8, the gravity ball 7 droops by itself through the cable 5, and the thorn head 12 pierces the bottom layer of the seabed to enhance the horizontal anti-skid ability.

[0041] The embedded rods 8 at the cross frame 3 can be inserted into the seabed at different heights according to the height of the seabed. After the embedded rods 8 are vertically set up, the screw pins 13 are inserted into the ring sleeves 11 to keep the ends of the screw pins 13 in a locked state with the sliding embedded rods 8. The rings 4 and the cables 5 can make the lower end gravity ball 7 contact the upper surface of the seabed, and the multiple spikes 12 on the outer surface of the gravity ball 7 can penetrate into the seabed to enhance the stability of the embedded rods 8. When the embedded rods 8 are assembled, the cross frame 3 and the erection beam 1 can be used to erect pipes on the seabed.

[0042] Push the baffle 15, the shift wheel 31 rolls on the upper surface of the cross frame 3, and the slide 17 drives the reverse pipe frame curved plate 10 to move, adjusting the position of the pipeline. The shift wheel 31 rolls inside the multiple sets of arc grooves 32 and squeezes the pressure spring 29 inside the slide shell 30 until the two sets of pipeline flanges correspond to each other. The shift wheel 31 is clamped in the corresponding arc groove 32. In the absence of a driving force, the pressure spring 29 can firmly clamp the push rod 34 at the top, forcing the push rod 34 to be clamped in the corresponding arc groove 32, thereby clamping the position of the slide 17.

[0043] When the pipe is placed between the two reverse pipe-supporting curved plates 10, the positioning spring 25 automatically contracts according to the diameter of the pipe, forcing the lower end V-shaped stop 36 to be clamped against the outer surface of the pipe. The clamping seat 22 can be clamped against the side surface of the pipe by means of the V-shaped stop 36, and the clamping seat 22 itself has a certain length, which can enhance the stability of the pipe clamping;

[0044] When the ocean current hits, the reverse pipe frame curved plate 10 and the diverter plates 19 and the paddles 9 at both ends of the cross frame 3 can guide the ocean current to flow through both sides of the device. The paddles 9 guide the eddy current away from the pipe connection, reducing the lateral thrust of the ocean current. The curved surface structure of the reverse pipe frame curved plate 10 will guide the water flow to one side and downward when it comes into contact with the water flow, causing the lateral impact force to be converted into longitudinal pressure (the drainage direction of the longitudinal pressure is downward transition). Therefore, when the ocean current contacts the reverse pipe frame curved plate 10, the lateral impact force can be weakened, thereby enhancing the stability of the baffle 15 and the slide 17 when holding the pipe, and preventing the pipeline from deflecting.

[0045] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
