Description

Technical Field

[0001] This utility model relates to the field of concrete counterweight subsea pipeline technology, and in particular to a wire mesh winding device and production line for spraying counterweights for marine oil and gas pipelines. Background Technology

[0002] Pipeline transportation is the most important and economical mode of transporting marine oil and gas resources. The safe and stable operation of marine oil and gas pipelines is crucial to ensuring energy transportation. In complex marine environments such as turbulent currents and anchor impacts, pipeline concrete counterweighting is used to ensure sufficient stability and good resistance to mechanical damage, effectively guaranteeing the safe and stable operation of pipelines underwater.

[0003] Currently, the internationally accepted methods for applying concrete to pipes are spraying and winding / extrusion. A counterweight spraying production line mainly consists of inlet / outlet pipe devices, wire mesh winding devices, coating devices, mixing devices, and a central control device. Its working principle is as follows: The finished concrete material, mixed uniformly according to a specific ratio by the mixing unit, is fed at a certain speed into the gap between a pair of high-speed rotating drums via a feeding belt. The concrete is sprayed onto the surface of the anti-corrosion pipe at a relatively high speed, while simultaneously winding reinforcing wire mesh to form a concrete counterweight layer that meets technical requirements. Finally, a scraper trims the sprayed surface to ensure a smooth appearance of the counterweight layer.

[0004] The applicant has discovered that the prior art has at least the following technical problems:

[0005] In actual operation, the wire mesh winding device of the counterweight spraying production line often experiences problems such as wire breakage and insufficient overlap distance. Moreover, when winding multiple layers of wire mesh, the pipe tail is not covered by the surface wire mesh, which seriously restricts the production rate and process quality.

[0006] Therefore, there is an urgent need to develop a wire mesh winding device and production line for counterweight spraying of marine oil and gas pipelines to solve the above-mentioned technical problems. Utility Model Content

The various technical effects of the preferred technical solutions among the many technical solutions provided by this utility model are detailed below.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0010] The supply module is used to accommodate the roll wound with wire mesh;

[0011] A buffer module is used to adjust the tension of the wire mesh during transmission;

[0012] A guiding module is used to guide the wire mesh to the outer surface of the tube to be counterweighted and adjust its winding position. The guiding module includes multiple transmission frames with adjustable spacing and a power device for driving the transmission frames to move. The spacing between the transmission frames is changed by the power device to control the coverage area of ​​the wire mesh at the tail of the tube to be counterweighted.

[0013] Preferably, it further includes a transmission module, which is used to guide the wire mesh to be transmitted along a preset path.

[0014] Preferably, the supply module includes a first frame structure, the first frame structure including a bottom frame arranged in a "Z" shape, a side frame, and a connecting frame for connecting the bottom frame and the side frame, wherein:

[0016] Guide wheels are provided inside the frame to transport the wire mesh sequentially along the roller and the guide wheels to the buffer module.

[0017] Preferably, at least two reel receiving positions are provided along the length direction of the receiving groove for receiving the reel, so that when the first wire mesh on the reel in one of the sets of reel receiving positions is about to be used up, the second wire mesh on another reel is overlapped to the first wire mesh.

[0018] Preferably, the buffer module includes a second frame structure and a braking assembly, a tension adjusting wheel assembly, and a sliding guide mechanism disposed on the second frame structure, wherein:

[0019] The braking assembly is used to provide braking resistance when the wire mesh overlaps;

[0020] The tension adjusting wheel assembly can be displaced along a preset trajectory via the sliding guide mechanism to dynamically balance the tension fluctuations during the transmission of the wire mesh.

[0021] Preferably, the sliding guide mechanism is provided on the side wall of the second frame structure, the tension adjusting wheel set includes a buffer wheel installed in the sliding guide mechanism and an auxiliary guide wheel installed on the top of the second frame structure, and the braking assembly includes a brake, which is located on the top of the second frame structure.

[0022] Preferably, the sliding guide mechanism includes two parallel slide rails, and the tension adjusting wheel set includes at least one set, each set of the tension adjusting wheel set including one buffer wheel and two auxiliary guide wheels, wherein,

[0025] Preferably, the power unit includes a cylinder.

[0026] A production line for spraying counterweights for marine oil and gas pipelines includes the aforementioned wire mesh winding device for spraying counterweights for marine oil and gas pipelines.

[0027] This utility model provides a wire mesh winding device and production line for counterweight spraying of marine oil and gas pipelines. By setting up a supply module to accommodate the wire mesh-wound reel, it ensures continuous output of the wire mesh during the counterweight spraying process. Combined with a buffer module for dynamic adjustment of transmission tension, it effectively avoids problems such as wire mesh breakage, slackness, or overstretching due to tension fluctuations, ensuring the stability and continuity of wire mesh transmission, reducing production stoppages caused by wire mesh transmission interruptions, and improving production efficiency. The guiding module, through multiple adjustable-gap transmission frames and a power device, can precisely change the spacing between the transmission frames, thereby flexibly controlling the winding position of the wire mesh on the outer surface of the pipe to be counterweighted. Especially in the final stage of counterweight spraying at the tail of the pipe, adjusting the spacing of the transmission frames ensures that the wire mesh tightly covers the tail area. This solves the problem of counterweight layer loss at the tail of the pipe due to lack of wire mesh winding when applying multiple layers of wire mesh in traditional devices, significantly improving the integrity and structural strength of the counterweight layer, and enhancing the overall quality and service life of the marine oil and gas pipeline.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] Figure 1 This is a structural schematic diagram of this embodiment, as shown below. Figure 1 As shown, this embodiment provides a wire mesh winding device for counterweight spraying of marine oil and gas pipelines, including a supply module 1, a buffer module 2, and a guide module 3 arranged in sequence.

[0040] The supply module 1 is used to accommodate the roll 4 on which the wire mesh 5 is wound. Specifically, in this embodiment, the supply module 1 includes a frame for supporting the roll 4, the roll being able to rotate freely around its own axis, and the wire mesh being continuously released from the roll. The buffer module 2, located downstream of the supply module 1, is used to adjust the tension of the wire mesh 5 during transmission. The guide module 3 is used to guide the wire mesh 5 to the outer surface of the counterweight tube 10 and adjust its winding position.

[0041] like Figure 2 As shown, the guide module 3 in this embodiment includes multiple transmission frames 31 with adjustable spacing and a power device 32 for driving the transmission frames 31 to move. The power device 32 drives the change of the spacing between the transmission frames 31 to control the coverage area of ​​the wire mesh 5 at the tail of the counterweight tube 10.

[0042] Specifically, the power unit 32 in this embodiment includes a cylinder. The guide module 3 also includes a rectangular frame body 33, which provides rigid support for the entire guide module 3, ensuring the relative position stability of components such as the transmission frame 31 and the cylinder. The transmission frame 31 is disposed within the frame body 33, and the inner wall of the frame body 33 is provided with a limiting guide structure 34, which is used to make the transmission frame 31 move along the direction set by the guide structure, ensuring the straightness of the movement of the transmission frame 31 and preventing the wire mesh from becoming entangled or skewed due to path deviation.

[0043] Optionally, the limiting guide structure 34 in this embodiment can be a sliding groove provided on the upper and lower inner walls of the frame body 33 and a slider provided on the upper and lower ends of the transmission frame 31, or it can be a track provided on the upper and lower inner walls of the frame body 33 and a pulley structure provided on the upper and lower ends of the transmission frame 31. Two sets of cylinders are provided, located on the left and right sides of the frame body 33 respectively, and the piston rods of the two cylinders are connected to the leftmost and rightmost transmission frames 31 in the frame body 33 respectively.

[0044] In actual production and use, 2-3 transmission frames 31 are set according to the number of winding layers. For example, 2 transmission frames 31 are set for single-layer winding, and 3 transmission frames 31 are set for double-layer winding. The multiple transmission frames 31 are arranged in parallel, and the spacing between every two transmission frames 31 and between the transmission frame 31 and the inner wall of the frame body 33 can be adjusted. The guide module 3 is used to adjust the lateral displacement of the wire mesh to ensure that it enters the winding area of ​​the counterweight tube 10 along the preset trajectory.

[0045] As an optional implementation method, such as Figure 3 As shown, the supply module 1 includes a first frame structure, which includes a bottom frame 11, a side frame 12, and a connecting frame 13 for connecting the bottom frame 11 and the side frame 12 in a "Z" shape.

[0046] The bottom frame 11 is provided with a receiving groove 110 for accommodating the scroll 4. The side wall of the receiving groove 110 is hinged to a rocker arm 7, which can abut against the scroll 4 to fix the position of the scroll 4. The frame 12 is provided with a guide wheel 121 for transmitting the wire mesh 5 sequentially along the scroll 4 and the guide wheel 121 to the buffer module 2.

[0047] The first frame structure of the supply module 1 adopts a "Z" shaped frame, which is compact and saves installation space. The receiving groove 110 is used to receive the roll 4, and the roll 4 is fixed by the rocker arm 7. When in use, the roll 4 can be quickly released by shaking the rocker arm 7 and then replaced. The operation is simple and convenient. The guide wheel 121 can ensure the stability of the wire mesh transmission direction and reduce the initial transmission deviation.

[0048] As an optional implementation, at least two roll receiving positions for receiving the roll 4 are provided along the length direction of the receiving groove 110, for overlapping the second wire mesh on the other roll to the first wire mesh when the first wire mesh on the roll 4 in one set of roll receiving positions is about to be used up.

[0049] By setting up multiple reel accommodating positions, the problem of downtime for replacement after a single reel is used up is avoided, significantly improving production efficiency. During use, hooks or other connectors allow for quick overlap, reducing interruption time in wire mesh transmission and minimizing winding quality issues caused by downtime.

[0050] In this embodiment, at least two sets of reel accommodating positions are provided to achieve one-for-one or one-for-multiple-for-one backup. In actual production and use, when the first wire mesh of the reusable reel is about to run out, there is no need to stop the machine. The head of the second wire mesh of the spare reel can be directly overlapped with the tail of the first wire mesh to ensure the continuity of transmission and solve the production interruption problem caused by machine stoppage for reel replacement in traditional single-reel designs.

[0051] As an optional implementation, the buffer module 2 includes a second frame structure 21 and a braking assembly 22, a tension adjusting wheel set 23 and a sliding guide mechanism 24 disposed on the second frame structure 21.

[0052] Among them, the braking component 22 is used to provide braking resistance when the wire mesh 5 overlaps; the tension adjusting wheel group 23 can be displaced along a preset trajectory through the sliding guide mechanism 24 to dynamically balance the tension fluctuations of the wire mesh 5 during transmission.

[0053] In this embodiment, by setting a braking component 22 in conjunction with a tension adjusting wheel set 23, the tension of the wire mesh is stabilized during the overlapping process, avoiding breakage caused by sudden tension changes. The tension adjusting wheel set 23 can be displaced along a preset trajectory via a sliding guide mechanism 24. When the tension increases, the tension adjusting wheel set 23 is displaced along the sliding guide mechanism 24 to release the tension; when the tension decreases, it is displaced in the opposite direction to tighten the wire mesh 5, avoiding breakage caused by excessive looseness or tightness. This achieves dynamic adjustment, reduces the range of tension fluctuations, and improves transmission stability.

[0054] As an optional implementation, a sliding guide mechanism 24 is provided on the side wall of the second frame structure 21. The tension adjusting wheel assembly 23 includes a buffer wheel 231 installed in the sliding guide mechanism 24 and an auxiliary guide wheel 232 installed on the top of the second frame structure 21. The braking assembly 22 includes a brake, which is located on the top of the second frame structure 21. The brake includes a power component and a pressure block connected below the power component. The power component can be a cylinder. The pressure block is pressed down by the action of the power component to temporarily brake the wire mesh 5 on the top of the second frame structure 21. Through reasonable layout, the overall structure is compact and the synergy is enhanced. The brake is located on the top of the second frame structure 21, which ensures the synchronization of braking and tension adjustment and improves the buffering effect.

[0055] As an optional implementation, the sliding guide mechanism 24 includes two parallel slide rails 241, and the tension adjusting wheel set 23 includes at least one set, each tension adjusting wheel set 23 including a buffer wheel 231 and two auxiliary guide wheels 232.

[0056] Among them, the buffer wheel 231 is connected to the two slide rails 241 through the bearing seat, and the auxiliary guide wheel 232 is fixedly connected to the top of the second frame structure 21. The three are distributed in a triangle so that the wire mesh 5 passes through one auxiliary guide wheel 232, the buffer wheel 231 and another auxiliary guide wheel 232 in sequence, forming an "S" shaped winding path.

[0057] In this embodiment, by setting two buffer wheels 231 and three auxiliary guide wheels 232, one buffer wheel and two adjacent auxiliary guide wheels 232 are arranged in a triangle, so that the wire mesh 5 is wound in an "S" shape, which increases the contact area between the wire mesh 5 and the wheel set and improves the tension adjustment sensitivity; the parallel slide rails 241 can ensure the smooth displacement of the buffer wheel 231 and further reduce tension fluctuations.

[0058] In actual production and use, the number of sliding guide mechanisms 24 corresponds one-to-one with the number of buffer wheels 231.

[0059] As an optional implementation method, such as Figure 4As shown, the wire mesh winding device for counterweight spraying of sub-marine oil and gas pipelines also includes a transmission module 6, which guides the wire mesh 5 along a preset path. By setting the transmission module 6 to standardize the transmission path of the wire mesh, the problem of uneven winding caused by path deviation is reduced, and the uniformity of the distribution of the wire mesh 5 in the counterweight layer is improved.

[0060] Specifically, in this embodiment, at least one set of transmission modules 6 is provided. The transmission module 6 includes a third frame structure, within which multiple guide wheels 61 are provided. The multiple guide wheels 61 can gradually adjust the transmission angle of the wire mesh 5 to adapt to the winding requirements of different pipe diameters. The multiple sets of transmission modules 6 can flexibly adapt to the production line layout, enhancing the versatility of the device.

[0061] This embodiment also includes a control system. The cylinder and brake are electrically connected to the control system. Specifically, the control system includes a PLC, which can preset the transmission path of the wire mesh 5 and the position parameters of the tail of the counterweight tube 10. The control system automatically controls the extension and retraction of the cylinder and the opening and closing of the brake, thereby achieving automated production.

[0062] This embodiment also provides a production line for spraying counterweights for marine oil and gas pipelines, including the aforementioned wire mesh winding device for spraying counterweights for marine oil and gas pipelines. Integrating this wire mesh winding device into the production line achieves integrated operation of counterweight spraying and wire mesh winding, improving the automation level and production efficiency of the entire production line; ensuring stable quality of the counterweight layer; and reducing the later maintenance costs of marine oil and gas pipelines.

[0063] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
