Description

Technical Field

[0001] The invention belongs to the technical field of pipeline supports and hangers, and in particular relates to a shock-absorbing and corrosion-resistant pipeline support and hanger for an offshore drilling platform. Background Art

[0002] The pipe supports and hangers used on offshore drilling platforms are pipe support and fixing devices specially designed for use in marine environments. They are an indispensable part of the pipeline system of offshore drilling platforms and play a vital role in the safe operation of pipelines. The primary task of pipe supports and hangers is to bear the weight of the pipeline, which includes the weight of the pipeline itself, the load of the insulation or sound insulation structure, and the load brought by the medium in the pipeline. Through the supports and hangers, the deformation of the pipeline in all directions can be effectively limited, controlled and constrained to ensure the stability of its shape and prevent the pipeline from moving in unexpected directions. The supports and hangers can also be used to limit or mitigate pipeline vibrations caused by external factors, as well as vibrations generated by the operation of equipment such as pumps, to ensure the stable operation of the pipeline system. However, existing pipe supports and hangers used on offshore drilling platforms cannot adjust their shock-absorbing effects in real time according to the intensity of the up and down shaking of the platform, which makes the pipeline susceptible to vibration damage and reduces its service life. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a shock-absorbing and corrosion-resistant pipe support and hanger for an offshore drilling platform, which effectively solves the problem that the existing pipe support and hanger for offshore drilling platforms in the above background technology cannot adjust its shock-absorbing effect in real time according to the intensity of the up and down shaking of the platform, causing the pipeline to be easily damaged by vibration, thereby reducing its service life.

[0004] To achieve the above object, the present invention provides the following technical solution: a shock-absorbing and corrosion-resistant pipe support hanger for an offshore drilling platform, including a support frame. Above the support frame is provided a positioning plate. In the middle of the top of the support frame is placed a pipe body. A locking hoop is sleeved on the surface of the pipe body. The bottom of the locking hoop is fixedly connected to the top of the support frame through bolts. In the middle of the bottom of the positioning plate is fixedly installed a vibration sensor. On one side of the bottom of the positioning plate is fixedly installed a control panel. At both ends of the bottom of the positioning plate are fixedly installed mounting cylinders. Inside each mounting cylinder is provided a piston disk. On both piston disks are symmetrically provided two adjustment holes. At the bottom of each piston disk is provided a mounting groove. Inside both mounting grooves are rotatably installed adjustment disks through shaft seats. At the lower end of the inside of each mounting cylinder is fixedly installed a piston ring. Inside each piston ring is inserted a sleeve. Inside both sleeves are respectively rotatably installed shaft rods through three bushings. At the upper ends of the surfaces of both shaft rods are rotatably connected to the upper ends of the inside of both sleeves through sealed shafts. The tops of both shaft rods are respectively fixedly connected to both adjustment disks. At the lower ends of the surfaces of both sleeves are respectively fixedly connected to both ends of the upper part of the support frame through fixed sleeves. On the surfaces of both sleeves are provided elastic reset components. On one side of the support frame is fixedly installed a driving motor. At the output end of the driving motor is provided a transmission component. The transmission component is in transmission connection with both adjustment disks. When the driving motor operates, power is output to both adjustment disks through the transmission component, so that both adjustment disks rotate to adjust the opening sizes of the two adjustment holes.

[0005] Preferably, the elastic reset components include two springs. The two springs are respectively sleeved on the surfaces of the two sleeves, and the tops of the two springs are respectively fixedly connected to the bottom ends of the two mounting cylinders. At the bottoms of the two springs are fixedly installed pushing disks, and the two pushing disks are respectively fixedly installed on the surfaces of the two sleeves.

[0006] Preferably, on both sides of the top of the support frame are fixedly installed support plates. On the sides of the two support plates close to each other are fixedly installed sliding sleeves through fixing blocks. Inside both sliding sleeves are inserted sliding rods. The tops of both sliding rods are fixedly connected to the lower side of the positioning plate.

[0007] Preferably, the transmission component includes an upper gear. The upper gear is fixedly installed at the output end of the driving motor. The lower part of the upper gear is meshed with a lower gear. Between one side of the lower gear and the upper gear is rotatably installed a positioning frame. One end of the positioning frame is fixedly connected to the support frame.

[0008] Preferably, on the other side of the lower gear is fixedly installed a rotating shaft. On the surface of the rotating shaft is rotatably installed a bearing. The top of the bearing is fixedly connected to the inner top of the support frame through a fixing rod.

[0009] Preferably, at one end of the rotating shaft is fixedly installed a worm. At one end of the worm is rotatably installed a positioning seat. The top of the positioning seat is fixedly connected to the inner top of the support frame.

[0010] Preferably, a worm gear is meshed and connected to the upper part of the surface of the worm. A rotating rod is fixedly installed in the middle of the worm gear. Four rotating sleeves are rotatably installed on the surface of the rotating rod at equal intervals. The tops of the four rotating sleeves are fixedly connected to the inner top of the support frame through fixed heads.

[0011] Preferably, driving bevel gears are fixedly installed at both ends of the rotating rod. One end of each of the two driving bevel gears away from each other is rotatably connected to the inner walls at both ends of the support frame through rotating seats. The upper parts of the surfaces of the two driving bevel gears are meshed and connected to driven bevel gears. The tops of the two driven bevel gears are fixedly connected to the bottoms of the two shaft rods.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) During operation, when the offshore drilling platform sways up and down under the influence of the environment, it will drive the overall up and down sway of the pipeline support hanger. When the vibration sensor detects the up and down vibration, it will output the data to the control panel. When the up and down vibration force is small, the control panel will start the driving motor to rotate forward. When the driving motor rotates forward, it will drive the lower gear to rotate through the upper gear. When the lower gear rotates, it drives the rotating shaft to rotate inside the bearing. When the rotating shaft rotates, it drives the worm to rotate along the positioning seat. When the worm rotates, it drives the rotating rod to rotate inside the four rotating sleeves through the worm gear. When the rotating rod rotates, it drives the two driven bevel gears to rotate through the two driving bevel gears;

[0014] When the two driven bevel gears rotate, they drive the two shaft rods to rotate inside the six shaft sleeves and the two sealed shafts. When the two shaft rods rotate, they drive the two adjusting disks to rotate to expand the openings of the adjusting holes, thereby increasing the oil passing amount of the two adjusting holes, and thus reducing the damping effect of the piston disk;

[0015] (2) When the pipeline support and hanger bracket vibrates up and down, it will drive the support bracket to move up. When the support bracket moves up, the two sliding sleeves are driven to slide on the surfaces of the two sliding rods through the two support plates, thereby increasing the stability of the support bracket when it moves. When the support bracket moves up, it will drive the two sleeves to move up. When the two sleeves move up, they will drive the two piston discs to move up along the inside of the two mounting cylinders, thereby performing a damping effect through the cooperation of the hydraulic oil in the two mounting cylinders. Since the openings of the two adjustment holes are large, the hydraulic oil can pass through the two adjustment holes quickly, thereby reducing the damping force. When the two sleeves move up, they will also drive the two pushing discs to squeeze the two springs to contract, so that the two sleeves have an elastic reset effect, thereby avoiding the damping force being too large to push the piston disc when the up and down vibration force is small, so that the piston disc can still be pushed to achieve the damping shock reduction effect when the up and down vibration force is small; when the up and down vibration is large, the control panel will start the reverse operation of the driving motor. When the driving motor runs in the reverse direction, it will drive the adjusting disc to rotate through the transmission component to reduce the opening of the adjusting hole, thereby reducing the amount of oil flowing through the two adjusting holes, thereby increasing the damping force to cope with the large up and down vibration force;

[0016] (3) The existing pipeline support and hanger for offshore drilling platforms can adjust its damping and shock absorption effect in real time according to the intensity of the up and down shaking of the platform, thereby preventing the pipeline from being damaged by vibration and increasing its service life.

[0034] During operation, when the offshore drilling platform sways up and down under the influence of the environment, it will drive the overall up-and-down sway of the pipe support hanger. When the vibration sensor 5 detects the up-and-down vibration, it will output the data to the control panel 6.
