DETAILED DESCRIPTION

[0037] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations herein are intended to be illustrative in nature and not to limit the present invention.

[0038] In the description of this application, it should be understood that in the embodiments shown in the drawings, indications of directions or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions will also change accordingly.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0040] Risers in floating production storage and offloading (FPSO) vessels are long and heavy. Using traditional rubber lagging equipment can cause riser deflection and affect lagging quality, resulting in uneven lagging.

[0041] This embodiment provides a new type of riser rubber coating device 100, which can effectively improve the efficiency of riser rubber coating, reduce the labor intensity of operators, and ensure the quality of riser rubber coating. The specific scheme is explained through the following embodiments.

[0042] See also Figure 1 The riser rubber coating device 100 of this embodiment includes a rotating assembly 10 and a movable rubber coating assembly 20. The movable rubber coating assembly 20 is disposed on one side of the rotating assembly 10. The rotating assembly 10 and the movable rubber coating assembly 20 cooperate with each other to achieve rubber coating treatment on the riser.

[0043] Specifically, the slewing assembly 10 includes a support mechanism 11 and a rotating mechanism 12. The support mechanism 11 is used to support the rotating mechanism 12 and the riser to ensure the stability of the riser when the riser is encapsulated.

[0044] In some embodiments of the present application, the support mechanism 11 includes a fixed platform 111. The rotating mechanism 12 is rotatably disposed on the fixed platform 111 and connected to one end of the vertical pipe so that the vertical pipe can rotate along with the rotating mechanism 12.

[0045] The rotating mechanism 12 may include a rotating portion and a connecting portion. The rotating portion is rotatably mounted on the fixed platform 111. The connecting portion is disposed on the rotating portion. The connecting portion connects to the end of the riser. In some embodiments, the connecting portion may be a clamping structure that clamps the end of the riser, or an internal support structure that supports the inner circumference of the riser, as long as it can connect to the end of the riser and ensure the rotation of the riser. The specific configuration can be determined according to actual needs and is not limited here.

[0046] See Figures 1 to 4 The supporting mechanism 11 includes a first bracket 112, which is spaced apart from the fixing platform 111. The first bracket 112 is used to support the other end of the riser.

[0047] In some embodiments, the first bracket 112 includes a first lifting portion 1121 and a first supporting portion 1122. The first supporting portion 1122 is used to support the riser. Moreover, the first supporting portion 1122 can move on the slide rail 13. The first lifting portion 1121 is connected to the first supporting portion 1122. The first lifting portion 1121 can move up and down so that the first supporting portion 1122 can move up and down with the first lifting portion 1121. Therefore, the operator can adjust the height of the first supporting portion 1122 through the first lifting portion 1121 to ensure that the head and tail sections of the riser, one end of which is connected to the fixed platform 111 and the other end of which is connected to the first bracket 112, are level, so as to facilitate the subsequent rubber coating treatment of the riser.

[0048] First supporting portion 1122 includes two first supporting rollers 11221 arranged in parallel. The riser is placed between the two first supporting rollers 11221 and contacts the surfaces of the two first supporting rollers 11221. The provision of first supporting rollers 11221 facilitates the rotation of the riser and effectively reduces the friction between the first supporting portion 1122 and the riser during rotation.

[0049] In some embodiments, the first bracket 112 includes a pressure arm 1123 and a pressure wheel 1124. One end of the pressure arm 1123 is rotatably connected to the first support portion 1122, and the other end of the pressure arm 1123 is provided with the pressure wheel 1124. The riser is clamped between the pressure wheel 1124 and the first support portion 1122. This arrangement effectively prevents the riser from bouncing or even detaching from the first bracket 112 during rotation by the rotation mechanism 12, thereby effectively improving the stability of the riser during rotation.

[0050] In some embodiments, the first support portion 1122 further includes two spaced-apart support plates 11222. The side of the support plates 11222 facing the pressure arm 1123 is curved, with the center of the curved side recessed toward the first support. The support plates 11222 and pressure arm 1123 cooperate to effectively and stably clamp the riser to the first bracket 112.

[0051] The arcuate side is provided with a plurality of mounting areas 11222a adapted to connect the two ends of the first supporting wheels 11221. This arrangement enables the operator to adaptively adjust the spacing between the two first supporting wheels 11221 according to different diameters of the riser, which is conducive to better supporting the riser.

[0052] It should be noted that the riser can be straight or curved. A curved pipe here refers to a riser that includes a straight section and an elbow section. When the riser is curved, the rotation mechanism 12 is connected to one end of the straight section of the riser, and the first bracket 112 supports the other end of the straight section of the riser. The elbow section of the riser extends out of the first bracket 112 and hangs in the air. The riser rubber coating device 100 in this application is used to rubber coat the straight section of the riser, and the riser extension direction in this specification refers to the extension direction of the straight section of the riser.

[0053] In some embodiments of the present application, the swivel assembly 10 includes a slide rail 13, and the first bracket 112 is movably disposed on the slide rail 13. It can be understood that this arrangement makes the support structure of the riser rubber-coated device 100 of the present application highly versatile and capable of supporting risers of different lengths.

[0054] For ease of description, the extending direction between the fixed platform 111 and the first bracket 112 in the figure is defined as the length direction; the extending direction between the rotary component 10 and the movable rubber-coated component 20 is defined as the width direction.

[0055] In some embodiments, the slewing assembly 10 further includes a protective frame (not shown) that can slide on the slide rails 13. The protective frame is disposed on a side of the first bracket 112 away from the fixed platform 111. The protective frame can include a base frame, a top plate, and two vertical plates spaced apart from each other. The base frame, top plate, and two vertical plates together form a frame structure having a through hole. The ends of the vertical pipes can be positioned adjacent to or directly within the through hole.

[0056] The protective frame creates a spatial barrier, effectively preventing operators from accidentally approaching the ends of the risers during the rubber coating process. This is particularly true when coating risers with elbows, as the protective frame effectively prevents the elbows from rotating with the riser and causing accidental injury.

[0057] See also Figures 5 to 7 and combined Figure 1 The support mechanism 11 includes a second bracket 113, which is used to support the portion of the riser to be encapsulated. The second bracket 113 includes a second body 1134. The second body 1134 is movably mounted on the slide rail 13, allowing the second bracket 113 to be movably positioned between the fixed platform 111 and the first bracket 112.

[0058] The second bracket 113 includes a second lifting portion 1131 and a second supporting portion 1132. Both the second lifting portion 1131 and the second supporting portion 1132 are located on the second main body 1134. The second lifting portion 1131 and the second supporting portion 1132 are connected. The second lifting portion 1131 is capable of vertical movement, allowing the second supporting portion 1132 to follow the movement of the second lifting portion 1131. Therefore, the operator can adjust the second lifting portion 1131 to control the height of the second supporting portion 1132, thereby better supporting the portion of the riser to be encapsulated.

[0059] The second supporting portion 1132 is used to support the portion of the riser to be encapsulated. Specifically, the second supporting portion 1132 includes two second supporting rollers 11321 arranged side by side in the width direction. When the second supporting portion 1132 supports the riser, the riser is placed between the two second supporting rollers 11321, and the outer circumference of the riser contacts the surfaces of the two second supporting rollers 11321. The axis of the second supporting rollers 11321 aligns with the axis of the riser.

[0060] In some embodiments of the present application, the second bracket 113 further includes a turning tool device 1133. The turning tool device 1133 includes a turning tool. After the riser is coated and vulcanized, it must undergo turning operations to meet the requirements for subsequent connection between the risers. For example, after the adhesive tape wrapped around the riser is vulcanized to form a rubber layer wrapped around the riser, the turning tool device 1133 can perform various processing operations on this rubber layer, such as beveling or stepping.

[0061] See Figures 8 to 10 and combined Figure 1 In some embodiments, the support mechanism 11 further includes a third bracket 114. The third bracket 114 is movably mounted on the slide rail 13. The third bracket 114 is disposed near the fixed platform 111. A third lifting portion 1141 is connected to the third supporting portion 1142. The third lifting portion 1141 is capable of vertical movement, so that the third supporting portion 1142 can move up and down with the third lifting portion 1141. Therefore, an operator can control the height of the third supporting portion 1142 by adjusting the third lifting portion 1141.

[0062] The third supporting portion 1142 includes two third supporting rollers 11421 arranged side by side along the width direction. The axis of the third supporting rollers 11421 aligns with the axis of the riser. The riser is placed between the two third supporting rollers 11421 and can simultaneously contact both first supporting rollers 11221.

[0063] The third bracket 114 includes a third main body 1143 , on which the third lifting portion 1141 and the third supporting portion 1142 are disposed. The third main body 1143 is movably disposed on the slide rail 13 , so that the third bracket 114 can move on the slide rail 13 .

[0064] The first bracket 112, the second bracket 113 and the third bracket 114 cooperate to realize the loading and unloading between the vertical pipe and the rotating mechanism 12. Specifically, take the installation of the end of the vertical pipe on the rotating mechanism 12 as an example. Before connecting the vertical pipe to the rotating mechanism 12, an external transfer device can be used to place the two ends of the vertical pipe on the first bracket 112 and the third bracket 114 respectively, and the middle part of the vertical pipe is placed on the second bracket 113; then the first bracket 112, the second bracket 113 and the third bracket 114 are synchronously moved toward the fixed platform 111, so that one end of the vertical pipe gradually approaches the rotating mechanism 12; then the height of the supporting part is adjusted by controlling the lifting part on each bracket to ensure that the end of the vertical pipe can be connected to the rotating mechanism 12. The external transfer device can be a forklift, a crane, etc.

[0065] Once the rotating mechanism 12 on the fixed platform 111 is connected to the end of the standpipe, the operator can lower the third support portion 1142 by controlling the third lifting portion 1141 of the third bracket 114, releasing it from contact with the standpipe. If the standpipe accidentally loses contact with the rotating mechanism 12, it will fall onto the third bracket 114. Therefore, the third bracket 114 also serves as a safety aid, effectively reducing the possibility of accidents.

[0066] It should be noted that the arrangement of the supporting parts in the first bracket 112 , the second bracket 113 and the third bracket 114 enables the riser rubber coating device 100 of the present application to perform rubber coating on risers of different specifications.

[0067] See also Figure 1 The mobile lagging assembly 20 includes a moving mechanism 21 and a dispensing mechanism 22. The moving mechanism 21 is movable along the extension direction of the riser. The dispensing mechanism 22 is fixedly connected to the moving mechanism 21 so that it can follow the movement of the moving mechanism 21 and move along the extension direction of the riser. The dispensing mechanism 22 is capable of extruding an adhesive tape. The dispensing mechanism 22 extrudes the adhesive tape while moving along with the moving mechanism 21. The riser rotates under the action of the rotating mechanism 12, causing the adhesive tape to wrap around the outer circumference of the riser.

[0068] It can be understood that the arrangement of the glue discharging mechanism 22, the moving mechanism 21 and the rotating mechanism 12 effectively saves labor costs and time costs, improves the efficiency of the glue coating processing of the FPSO neutral pipe, and reduces the labor intensity of the operators. Only fewer operators are required to control the rotation of the rotating mechanism 12, the glue discharging mechanism 22 to discharge glue, and the movement of the moving mechanism 21.

[0069] The movable mechanism 21 can move from the first bracket 112 toward the fixed platform 111, so that the glue discharging mechanism 22 is wrapped from the end of the vertical tube near the first bracket 112 to the end of the vertical tube near the fixed platform 111. In this case, the second bracket 113 is on the side of the glue discharging mechanism 22 near the fixed platform 111. The movable mechanism 21 can also move from the fixed platform 111 toward the first bracket 112, so that the glue discharging mechanism 22 is wrapped from the end of the vertical tube near the fixed platform 111 to the end of the vertical tube near the first bracket 112. In this case, the second bracket 113 is on the side of the glue discharging mechanism 22 near the first bracket 112. The specific glue coating of the vertical tube can be based on actual working conditions and is not limited here. This embodiment is described as the second bracket 113 moving to the side of the glue discharging mechanism 22 near the first bracket 112.

[0070] After the riser is installed on the fixed platform 111 and the first bracket 112 of the support mechanism 11, the second bracket 113 moves to a position close to the glue dispensing mechanism 22. As the glue dispensing mechanism 22 moves with the moving mechanism 21 and applies glue to the riser, the second bracket 113 moves synchronously with the glue dispensing mechanism 22, promptly supporting the portion of the riser to be glued. This effectively avoids deflection at the riser during gluing, prevents the riser from sagging under gravity and affecting the gluing of the gluing mechanism, and effectively ensures the quality of the riser's glue.

[0071] In some embodiments of the present application, the mobile mechanism 21 includes a slide 211 and a guide rail 212. The guide rail 212 extends in the same direction as the vertical pipe. The slide 211 is mounted on the guide rail 212 and is movable along the direction of the guide rail 212. The glue dispensing mechanism 22 is mounted on the slide 211 of the mobile mechanism 21, so that the glue dispensing mechanism 22 can move along the vertical pipe as the slide 211 moves.

[0072] The glue discharging mechanism 22 includes an extruder 221 for extruding the adhesive tape. It should be noted that the adhesive tape is squeezed out, which can effectively eliminate bubbles in the adhesive tape and prevent the bubbles from affecting the quality of the adhesive coating.

[0073] The glue discharging mechanism 22 includes a temperature control system 222. The temperature control system 222 is electrically connected to the extruder 221. The temperature control system 222 is used to regulate the temperature of the extruder 221 to reach the softening temperature of the tape, thereby obtaining a softened tape. It should be noted that the softened tape has adhesion, which is conducive to the tape adhering to the vertical pipe and ensuring that the tape is not easy to loosen after being wrapped around the vertical pipe. Compared with the traditional manual glue coating operation, the setting of the temperature control system 222 and the extruder 221 reduces the process of brushing glue slurry on the surface of the vertical pipe or the rubber plate, which is conducive to improving the glue coating efficiency and shortening the construction period.

[0074] The glue dispensing mechanism 22 includes an operating table 223 and a control cabinet 224. The control cabinet 224 is electrically connected to the moving mechanism 21, rotating mechanism 12, operating table 223, extruder 221, and temperature control system 222. The operating table 223 can control the moving mechanism 21, rotating mechanism 12, operating table 223, extruder 221, and temperature control system 222 through the control cabinet 224. For example, by controlling the movement speed of the slide 211 in the moving mechanism 21, the spacing and overlap between the tapes wrapped around the riser can be controlled, thereby controlling the thickness of the rubber lagging. By controlling the travel distance of the moving mechanism 21, the total length of the rubber lagging on the riser can be controlled.

[0075] The riser rubber-coating device 100 further includes a rolling assembly 30 , which is disposed on the moving mechanism 21 so that the rolling assembly 30 can follow the moving mechanism 21 and move along the extension direction of the riser.

[0076] See Figure 11 and combined Figure 1 The rolling assembly 30 includes a roller 31, which is in contact with the riser. The roller 31 is used to press the tape wrapped around the outer circumference of the riser to remove the gas between the tape and the riser, and between the tape layers wrapped around the riser, to ensure that the thickness of the rubber lagging is uniform and dense.

[0077] In some embodiments, the rollers 31 include a first roller 311 and a second roller 312. The first roller 311 is positioned opposite the tape loading position of the adhesive discharging mechanism 22. The second roller 312 is spaced apart from the first roller 311 and positioned downstream of the first roller 311. The first roller 311 and the second roller 312 sequentially press the wound tape.

[0078] The first roller 311 and the second roller 312 can be arranged on the same horizontal line, that is, the axis of the first roller 311 and the axis of the second roller 312 are on the same horizontal line. The first roller 311 and the second roller 312 can also be staggered, that is, the axis of the first roller 311 and the axis of the second roller 312 are not on the same horizontal line. The specific arrangement can be determined according to actual needs and is not limited here.

[0079] Roller assembly 30 also includes a telescopic arm 32, which is drive-connected to roller 31 to enable roller 31 to move toward or away from the riser. Telescopic arm 32 is electrically connected to an operating console 223, allowing an operator to control the telescopic arm 32's extension and retraction.

[0080] It will be appreciated that the first roller 311 and the second roller 312 are mounted on the telescopic arm 32. Before the riser is rubber-coated, a certain distance exists between the first roller 311, the second roller 312, and the riser. During the rubber-coating process, the telescopic arm 32 can be controlled to extend to bring the first roller 311 and the second roller 312 closer together until they abut against the riser. Furthermore, the force with which the first roller 311 and the second roller 312 press against the tape wrapped around the riser can be adjusted by controlling the telescopic arm 32.

[0081] In some embodiments, the roller 31 may also be provided with a drive unit 33. The drive unit 33 is disposed on the telescopic arm 32. The drive unit 33 is operatively connected to the second roller 312, and is used to move the second roller 312 toward or away from the riser. The drive unit 33 is electrically connected to the operating console 223, enabling an operator to control the drive unit 33 through the console 223. Compared to the telescopic arm 32, the drive unit 33 can achieve finer adjustment of the distance between the second roller 312 and the riser.

[0082] In some embodiments, the rolling assembly 30 includes a plurality of drive rollers (not shown) disposed between the extruder 221 and the roller 31 and spaced apart on the control cabinet 224 along the direction from the extruder 221 toward the roller 31. The extruded tape passes vertically through the gaps between the drive rollers and abuts against the outer periphery of each drive roller. The drive rollers support the tape between the extruder 221 and the roller 31, preventing it from drooping onto the slide 211 due to gravity. Furthermore, the drive rollers ensure that the tape is tensioned and flat.

[0083] See also Figure 12 and combined Figure 1 The riser rubber coating device 100 also includes a nylon belt winding assembly 40, which is arranged on the moving mechanism 21. The nylon belt winding assembly 40 is used to wrap the nylon belt 200 around the outer periphery of the riser.

[0084] In some embodiments, the nylon belt winding assembly 40 includes a torque motor 41 and a mounting portion 42. The mounting portion 42 is connected to the drive shaft 411 on the torque motor 41 so that the mounting portion 42 can rotate relative to the torque motor 41. The mounting portion 42 includes a reel 421 and baffles 422 provided on both sides of the reel 421. The nylon belt 200 is wound around the reel 421 of the mounting portion 42. The torque motor 41 is electrically connected to the operating console 223. The operator can control the forward or reverse rotation of the torque motor 41 through the operating console 223, and can control the rotation rate of the torque motor 41, as well as meet the force adjustment requirements for winding the nylon belt 200, to ensure uniform and stable force, so that the nylon belt 200 is firmly wound around the outer circumference of the riser. The baffle 422 is detachably connected to the reel 421 to facilitate the operator to replace the nylon belt 200.

[0085] After the riser is rubber-coated, the tape is wrapped around the riser's circumference to form a rubber layer, and the nylon belt 200 is used to secure this rubber layer. Specifically, one end of the nylon belt 200 is first connected to the riser. Then, the rotating mechanism 12, the moving mechanism 21, and the torque motor 41 are activated, causing the torque motor 41 to rotate synchronously with the rotating mechanism 12. The riser rotates under the action of the rotating mechanism 12, and the nylon belt winding assembly 40 follows the movement of the moving mechanism 21, moving along the extension direction of the riser. The mounting portion 42 of the nylon belt winding assembly 40 is uprighted under the action of the torque motor 41, releasing the nylon belt 200, thereby wrapping the nylon belt 200 around the riser's circumference.

[0086] After the nylon strap 200 is wrapped, the riser is transferred to the vulcanizing unit for vulcanization. After vulcanization, the external transfer unit can be used to reinstall the riser onto the swivel assembly 10. The swivel assembly 10, the moving mechanism 21 within the movable rubber lagging assembly 20, and the nylon strap wrapping assembly 40 then automatically remove the nylon strap 200 from the riser and recycle it onto the mounting portion 42 of the nylon strap wrapping assembly 40.

[0087] It can be seen from the above technical solution that the riser rubber coating device 100 provided in this embodiment has the following advantages and beneficial implementation effects.

[0088] The riser rubber coating device 100 includes a rotating assembly 10 and a movable rubber coating assembly 20. The riser can be securely mounted on a support mechanism 11 within the rotating assembly 10. The riser can rotate under the action of a rotating mechanism 12 within the rotating assembly 10. A rubber dispensing mechanism 22 within the movable rubber coating assembly 20 can extrude an adhesive tape and can move along the extension direction of the riser in conjunction with the movable mechanism 21. As the riser rotates, the rubber dispensing mechanism 22 moves while extruder tape, wrapping the tape around the outer circumference of the riser and achieving rubber coating of the riser. The interaction of the rotating mechanism 12, the rubber dispensing mechanism 22, and the movable mechanism 21 enables automatic rubber coating of the riser, effectively saving manpower, reducing the workload of operators, improving the efficiency of rubber coating of FPSO risers, and shortening the riser rubber coating and vulcanization process.

[0089] The provision of the second bracket 113 within the support mechanism 11 provides timely support for the riser portion to be rubber-coated, effectively preventing deflection during the riser rubber coating process and ensuring the quality of the riser rubber coating. Furthermore, the provision of the first bracket 112, the second bracket 113, and the third bracket 114 makes the riser rubber coating apparatus 100 of this application highly versatile, allowing it to be rubber-coated for risers of varying lengths and diameters.

[0090] In addition, the riser lagging apparatus 100 includes a roller assembly 30, which tightens the rubber lagging on the riser. The riser lagging apparatus 100 also includes a nylon strap wrapping assembly 40. The nylon strap wrapping assembly 40, the movable assembly of the movable lagging assembly 20, and the rotary assembly 10 cooperate to wrap the nylon strap 200 around the riser and remove it from the riser.
