Description

Technical Field

[0001] This invention relates to the temporary tooling pipe structure for FPSO cargo oil systems. Background Technology

[0002] Most FPSO projects currently being built in China only complete the hull construction. The topside section will be installed at a shipyard selected by the owner overseas. The unloading equipment and flow meters of the cargo oil system will be installed on the topside. Based on the current completion status, the existing piping system cannot meet all commissioning requirements. Therefore, in order to meet all the commissioning requirements of the entire cargo oil system and verify the corresponding contents in the technical specifications, a set of temporary tooling pipes is needed to design a commissioning method to meet the commissioning requirements and complete the commissioning of the entire cargo oil system.

[0003] While temporary tooling pipes can shorten commissioning time and save on testing manpower costs when put into use, they lack a quick-connection function when docking with the corresponding transmission pipe. This makes docking time-consuming and laborious, greatly increasing the user's workload. Furthermore, the poor sealing after docking can easily lead to leakage and unnecessary waste. In addition, the transmission pipe used for docking lacks support function, making it prone to shaking during oil supply, which can cause the connection between the transmission pipe and the temporary tooling pipe to break, thus affecting normal use. Summary of the Invention

[0004] The purpose of this invention is to provide a temporary tooling pipe structure for FPSO cargo oil systems to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The temporary tooling pipe structure of the FPSO cargo oil system includes: a main structure including a temporary tooling pipe, with a shell on both sides of the temporary tooling pipe, the side of the shell near the temporary tooling pipe being fixedly connected to the surface of the temporary tooling pipe, and a docking groove being provided on one side of the shell;

[0007] A sealing mechanism is located at one end of the temporary tooling tube and is used in conjunction with the temporary tooling tube.

[0008] A quick positioning mechanism, located inside the housing, is used in conjunction with a sealing mechanism.

[0009] A support mechanism is located at the bottom of the sealing mechanism and is used in conjunction with the sealing mechanism.

[0010] Compared with the prior art, the beneficial effects of the present invention are: it solves the problem that when using temporary tooling pipes, it is necessary to connect the temporary tooling pipes with the corresponding transmission pipes. The existing temporary tooling pipes do not have a quick connection function, which makes the connection time-consuming and laborious, greatly increasing the workload of users. Moreover, the sealing after connection is poor, which can easily lead to leakage and unnecessary waste. At the same time, the transmission pipes used for connection do not have a support function, which can easily cause the transmission pipes to shake during oil supply, thereby causing the connection between the transmission pipe and the temporary tooling pipe to break, thus affecting normal use.

[0011] As a further embodiment of the present invention: the sealing mechanism includes a transmission pipe, one end of which is inserted into the interior of a temporary tooling pipe. Both sides of the transmission pipe are fixedly connected to mating blocks. One side of each mating block is fixedly connected to a docking block that mates with a docking groove. Both sides of each docking block have positioning grooves that mate with a quick positioning mechanism. The transmission pipe also works in conjunction with a support mechanism. The beneficial effect of this embodiment is that by setting a sealing mechanism, the sealing performance after the transmission pipe and the temporary tooling pipe are docked can be effectively improved, solving the problem of poor sealing after docking, which easily leads to leakage and unnecessary waste.

[0012] As a further aspect of the present invention: the rapid positioning mechanism includes a track block, and a positioning rod is fixedly connected to one side of the track block. There are two positioning rods, with the end of each positioning rod near the docking block penetrating into the docking groove and cooperating with it. Control rods are fixedly connected to the sides of the two positioning rods that are away from each other, and the end of each control rod away from the positioning rod penetrates to the outside of the housing. The beneficial effect of this embodiment is that by setting up a rapid positioning mechanism, the transmission pipe can be inserted into the temporary tooling pipe by aligning the docking block and the docking groove, while simultaneously allowing the docking block to enter the docking groove. Then, the rapid positioning mechanism positions the pipe, solving the problem that existing temporary tooling pipes lack rapid docking functionality, resulting in laborious and time-consuming docking and greatly increasing the user's workload.

[0013] As a further embodiment of the present invention: the support mechanism includes an arc-shaped support block, the inner wall of which is fixedly connected to the outer surface of the transmission pipe. A base plate is provided at the bottom of the arc-shaped support block, and a sleeve is fixedly connected to the top of the base plate. An adjusting rod is inserted into the inside of the sleeve, and the top of the adjusting rod is fixedly connected to the bottom of the arc-shaped support block. A mating hole is provided on the surface of the adjusting rod. The beneficial effect of this embodiment is that by setting up a support mechanism, the sleeve and the base plate can be adjusted along the trajectory of the adjusting rod, so that the support frame under the base plate contacts the ground, thereby supporting the transmission pipe. This solves the problem that the transmission pipe does not have a support function and is very prone to shaking during oil supply, which can cause the connection between the transmission pipe and the temporary tooling pipe to break, thus affecting normal use.

[0014] As a further aspect of the present invention: a silicone sealing ring is fixedly connected to the inner wall of the temporary tooling pipe, and the silicone sealing ring is used in conjunction with the transmission pipe. The beneficial effect of this embodiment is that by setting the silicone sealing ring, the sealing performance after the temporary tooling pipe and the transmission pipe are connected can be improved, preventing leakage.

[0015] As a further aspect of the present invention: a track rod is inserted inside the track block, both ends of which are fixedly connected to the inner wall of the housing; a sliding hole is provided on one side of the track block to cooperate with the track rod. The beneficial effect of this embodiment is that by setting the track rod and the sliding hole, the position of the track block and the positioning rod can be restricted, making their operation more stable.

[0016] As a further aspect of the present invention: a spring is fixedly connected to the side of the track block away from the positioning rod, and two springs are provided. The end of each spring away from the positioning rod is fixedly connected to the inner wall of the housing. The beneficial effect of this embodiment is that by providing springs, a pushing force can be applied to the track block and the positioning rod, allowing the positioning rod to accurately enter the positioning groove.

[0017] As a further aspect of the present invention: a threaded rod is threadedly connected to one side of the sleeve, the threaded rod engaging with a mating hole, and a threaded hole for engaging with the threaded rod is formed on the surface of the sleeve. The beneficial effect of this embodiment is that by providing the threaded rod and threaded hole, the threaded rod can be screwed into the mating hole, thereby fixing the position of the sleeve and the base plate.

[0018] As a further aspect of the present invention: the number of mating holes is several, and they are evenly distributed on the surface of the adjusting rod. The beneficial effect of this embodiment is that, by providing mating holes, after the position of the sleeve and the base plate is adjusted, the threaded rod engages with the corresponding mating hole to achieve a limiting position.

[0019] As a further aspect of the present invention: a support frame is fixedly connected to the bottom of the base plate, and the number of support frames is two. Anti-slip pads are fixedly connected to both sides of the bottom of each support frame. The beneficial effect of this embodiment is that by setting up support frames and anti-slip pads, the stability after contact with the ground can be improved, while preventing slippage.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 8 In this embodiment of the invention, the temporary tooling pipe structure of the FPSO cargo oil system includes: the main body 100 includes a temporary tooling pipe 101, and a housing 102 is provided on both sides of the temporary tooling pipe 101. The side of the housing 102 close to the temporary tooling pipe 101 is fixedly connected to the surface of the temporary tooling pipe 101, and a docking groove 103 is provided on one side of the housing 102.

[0031] A sealing mechanism 200 is located at one end of the temporary tooling tube 101 and is used in conjunction with the temporary tooling tube 101.

[0032] The quick positioning mechanism 300 is located inside the housing 102 and works in conjunction with the sealing mechanism 200.

[0033] Support mechanism 400 is located at the bottom of sealing mechanism 200 and is used in conjunction with sealing mechanism 200.

[0034] In this invention, the sealing mechanism 200 includes a transmission pipe 201, one end of which is inserted into the interior of a temporary tooling pipe 101. Both sides of the transmission pipe 201 are fixedly connected to mating blocks 202. One side of each mating block 202 is fixedly connected to a docking block 203 that mates with a docking groove 103. Both sides of the docking block 203 are provided with positioning grooves 204 that mate with a quick positioning mechanism 300. The transmission pipe 201 is used in conjunction with a support mechanism 400. The beneficial effect of this embodiment is that by setting the sealing mechanism 200, the sealing performance after the transmission pipe 201 and the temporary tooling pipe 101 are docked can be effectively improved, solving the problem of poor sealing after the transmission pipe 201 and the temporary tooling pipe 101 are docked, which easily leads to leakage and unnecessary waste.

[0035] A silicone sealing ring 5 is fixedly connected to the inner wall of the temporary tooling pipe 101. The silicone sealing ring 5 is used in conjunction with the transmission pipe 201. The beneficial effect of this implementation scheme is that by setting the silicone sealing ring 5, the sealing performance of the temporary tooling pipe 101 after being connected to the transmission pipe 201 can be improved, and leakage can be prevented.

[0036] In this process, the user aligns the docking block 203 with the docking groove 103, inserts the transmission pipe 201 into the temporary tooling pipe 101, and simultaneously moves the docking block 203 into the docking groove 103. Then, the quick positioning mechanism 300 limits the docking block 203, thereby fixing the position of the transmission pipe 201. At this time, the surface of the transmission pipe 201 is in close contact with the silicone sealing ring 5, thus avoiding oil leakage. This solves the problem of poor sealing after the transmission pipe 201 and the temporary tooling pipe 101 are docked, which easily leads to leakage and causes unnecessary waste.

[0037] In this invention, the rapid positioning mechanism 300 includes a track block 301. A positioning rod 302 is fixedly connected to one side of the track block 301. There are two positioning rods 302. The end of the positioning rod 302 near the docking block 203 extends into the interior of the docking groove 103 and cooperates with the positioning groove 204. A control rod 303 is fixedly connected to the side of the two positioning rods 302 that are far away from each other. The end of the control rod 303 away from the positioning rod 302 extends into the outside of the housing 102. The beneficial effect of this embodiment is that by setting the rapid positioning mechanism 300, the transmission tube 201 can be inserted into the interior of the temporary tooling tube 101 by aligning the position of the docking block 203 and the docking groove 103. At the same time, the docking block 203 enters the interior of the docking groove 103. Then, the rapid positioning mechanism 300 positions it, which solves the problem that the existing temporary tooling tube 101 does not have a rapid docking function, which makes docking time-consuming and laborious and greatly increases the workload of the user.

[0038] A track rod 6 is inserted inside the track block 301. Both ends of the track rod 6 are fixedly connected to the inner wall of the housing 102. A sliding hole 7 is provided on one side of the track block 301 to cooperate with the track rod 6. The beneficial effect of this embodiment is that by setting the track rod 6 and the sliding hole 7, the position of the track block 301 and the positioning rod 302 can be restricted, making them more stable during operation.

[0039] Two springs 8 are fixedly connected to the side of the track block 301 away from the positioning rod 302. The end of the spring 8 away from the positioning rod 302 is fixedly connected to the inner wall of the housing 102. The beneficial effect of this embodiment is that by setting the spring 8, a pushing force can be exerted on the track block 301 and the positioning rod 302, so that the positioning rod 302 can accurately enter the interior of the positioning groove 204.

[0040] In this process, the user pushes the control lever 303 towards the side closer to the spring 8. The control lever 303 moves the track block 301 and the positioning rod 302 towards the side closer to the spring 8, causing the positioning rod 302 to leave the docking groove 103. Then, the user aligns the docking block 203 with the docking groove 103, inserts the transmission tube 201 into the temporary tooling tube 101, and simultaneously moves the docking block 203 into the docking groove 103. Releasing the control lever 303 causes the elastic force generated by the spring 8 to push the track block 301 and the positioning rod 302 away from the spring 8, causing the positioning rod 302 to enter the positioning groove 204, thus fixing the docking block 203 and restricting the position of the transmission tube 201. This solves the problem that the existing temporary tooling tube 101 does not have a quick docking function, which makes docking time-consuming and laborious, greatly increasing the user's workload.

[0041] In this invention, the support mechanism 400 includes an arc-shaped support block 401. The inner wall of the arc-shaped support block 401 is fixedly connected to the outer surface of the transmission pipe 201. A base plate 402 is provided at the bottom of the arc-shaped support block 401. A sleeve 403 is fixedly connected to the top of the base plate 402. An adjusting rod 404 is inserted into the inside of the sleeve 403. The top of the adjusting rod 404 is fixedly connected to the bottom of the arc-shaped support block 401. A mating hole 405 is provided on the surface of the adjusting rod 404. The beneficial effect of this embodiment is that by setting the support mechanism 400, the sleeve 403 and the base plate 402 can be adjusted along the trajectory of the adjusting rod 404, so that the support frame 11 under the base plate 402 contacts the ground, thereby supporting the transmission pipe 201. This solves the problem that the transmission pipe 201 does not have a support function and is very easy to shake during oil supply, which causes the connection between the transmission pipe 201 and the temporary tooling pipe 101 to break, thus affecting normal use.

[0042] A threaded rod 9 is threadedly connected to one side of the sleeve 403. The threaded rod 9 is used in conjunction with the mating hole 405. A threaded hole 10 is provided on the surface of the sleeve 403 to be used in conjunction with the threaded rod 9. The beneficial effect of this embodiment is that by setting the threaded rod 9 and the threaded hole 10, the threaded rod 9 can be screwed into the mating hole 405, thereby fixing the position of the sleeve 403 and the base plate 402.

[0043] The number of mating holes 405 is several and they are evenly distributed on the surface of the adjusting rod 404. The beneficial effect of this embodiment is that by setting mating holes 405, after the position of the sleeve 403 and the base plate 402 is adjusted, the threaded rod 9 can be engaged with the corresponding mating hole 405 to achieve the limit.

[0044] The bottom of the base plate 402 is fixedly connected to a support frame 11. There are two support frames 11. Anti-slip pads 12 are fixedly connected to both sides of the bottom of the support frame 11. The beneficial effect of this implementation is that by setting the support frame 11 and the anti-slip pads 12, the stability after contact with the ground can be improved, and slippage can be avoided.

[0045] In this process, the user can loosen the threaded rod 9 by turning it away from the mating hole 405. At this point, the sleeve 403 is no longer restricted. The user can then adjust the positions of the sleeve 403, the base plate 402, and the support frame 11 along the trajectory of the adjusting rod 404, so that the bottom of the support frame 11 contacts the ground, thereby providing a supporting force for the transmission pipe 201. Afterward, the user can reverse the rotation of the threaded rod 9 to allow it to enter the corresponding mating hole 405. This solves the problem that the transmission pipe 201 does not have a supporting function and is prone to shaking during oil supply, which could cause the connection between the transmission pipe 201 and the temporary tooling pipe 101 to break, thus affecting normal use.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
