Description

Technical Field

[0001] The invention belongs to the technical field of oil drilling platforms, and in particular relates to a hydraulic electric riser extension device. Background Art

[0002] In the operation of oil drilling platforms, seawater lifting pumps are used to extract seawater for firefighting and other purposes. In order to ensure that seawater can be effectively pumped to the platform, the lifting pipe needs to be gradually extended downward from the wellhead on the platform until its end is deep in the seawater. The traditional practice is to hang an electric hoist on the structural beam above the lifting pipe and operate the electric hoist to achieve the up and down movement of the lifting pipe. However, this method has obvious disadvantages. For example, the lifting pipe may shake greatly during movement, which not only easily leads to collision with the wellhead, but also accelerates corrosion in the high-salt and high-humidity marine environment due to paint peeling, thereby shortening the service life of the lifting pipe. In addition, manual suspension is required before each use of the electric hoist, which is not only inefficient, but also has the risk of unstable suspension, which may cause the lifting pipe to fall during operation. More importantly, the existing electric hoist solution cannot quickly stop the lifting pipe in an emergency, and cannot effectively respond to possible emergencies. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a hydraulic electric riser extension device to solve the problem of water pipe shaking caused by the electric hoist and improve construction safety by integrating an emergency brake function.

DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below. Figure 1 to Figure 2The embodiment of the present invention provides a hydraulic electric riser extension device for fixing a water lifting pipe 600, including a base 100, a mounting frame 200, a plurality of lifting components 300, a plurality of clamping components 400 and a plurality of roller components 500, wherein the lifting component 300 includes a lifting hydraulic arm 310, and the clamping component 400 is provided with a pop-up clamping hydraulic arm 410, the base 100 is fixed to the ground through a support leg 110, the mounting frame 200 is connected to the upper part of the base 100 through a plurality of lifting components 300, and the lifting hydraulic arm 310 can move up and down to drive the mounting frame 200 to move along the As the base 100 moves up and down, a plurality of roller assemblies 500 are fixed in a ring shape to the end surface of the mounting frame 200, and a freely retractable roller 510 is provided on the roller assembly 500. A plurality of clamp assemblies 400 are fixed in a ring shape to the lower end surface of the base 100, and a water pumping pipe 600 passes through the base 100 and the mounting frame 200. The outer wall 610 of the water pumping pipe 600 fits with the roller 510 to enable the water pumping pipe 600 to move up and down along the mounting frame 200. The clamp assembly 400 and the roller assembly 500 are electrically connected so that the clamp assembly 400 receives the brake stop signal sent by the roller assembly 500. The present invention achieves the coordinated work of a base 100, a mounting frame 200, a lifting assembly 300, a roller assembly 500 and a clamp assembly 400. The lifting and lowering of the mounting frame 200 is controlled by lifting the hydraulic arm 310. The roller assembly 500 is used for the up and down movement of the water pipe 600. The roller assembly 500 can detect the abnormal falling of the water pipe 600 and trigger the clamp assembly 400. The water pipe 600 is quickly clamped by the clamp hydraulic arm 410 to prevent it from further sliding down. This device not only reduces the damage to the surface of the water pipe 600, but also greatly improves the safety of the construction site and the convenience of operation. In addition, the position of the vertical pipe can be accurately adjusted by extending and retracting the lifting assembly 300 to ensure its stability and convenience during the extension process.

[0019] Furthermore, the base 100 is used to fix the entire extension device and bear the weight of the entire device. Of course, the present invention does not limit the specific structure of the base 100. Considering that the device is generally used on an oil drilling platform and is a large-scale device, preferably, refer to Figure 1The base 100 is supported by supporting legs, and a space is set between the base 100 and the ground to facilitate the installation and disassembly of other equipment. Of course, the present invention does not limit the specific structure of the support leg 110. Preferably, the support leg 110 is a Z-shaped support leg, and the two ends of the support leg 110 are respectively fixed to the lower end surface of the base 100 and the ground. Furthermore, the mounting frame 200 is fixed to the base 100 and can move up and down along the base 100 to provide a movable platform. The roller assembly 500 is fixed to the upper end surface of the mounting frame 200, the lifting assembly 300 is installed between the base 100 and the mounting frame 200, and the clamp assembly 400 is fixed to the lower end surface of the base 100. The lifting assembly 300 mainly realizes the up and down movement of the mounting frame 200 by retracting the hydraulic arm. Furthermore, the lifting assembly 300 also includes a first connecting plate 320, a second connecting plate 330 and a lifting hydraulic cylinder 340. The first connecting plate 320 is fixed to the edge of the mounting frame 200, one end of the lifting hydraulic arm 310 is fixed to the first connecting plate 320, the second connecting plate 330 is fixed to the lower end surface of the base 100, the lifting hydraulic cylinder 340 is fixed to the second connecting plate 330, and the other end of the lifting hydraulic arm 310 is plugged into the lifting hydraulic cylinder 340. Specifically, when the water lifting pipe 600 needs to be extended downward, the lifting hydraulic cylinder 340 can cause the lifting hydraulic arm 310 to retract, thereby lowering the mounting frame 200. Conversely, the mounting frame 200 can be raised, so that the water lifting pipe 600 can be accurately positioned and moved in the vertical direction. Furthermore, the lifting assembly 300 can not only realize the up and down movement of the water lifting pipe 600, but also ensure the structural stability of the entire device. Through the cooperation of the lifting hydraulic cylinder 340 and the lifting hydraulic arm 310, it is ensured that the remaining components installed on the mounting frame 200 machine can work stably at different heights, thereby ensuring the stability of the water lifting pipe 600 during movement. Furthermore, during the extension of the water lifting pipe 600, obstacles such as flanges will be encountered. By extending the lifting hydraulic arm 310 through the lifting hydraulic cylinder 340, the mounting frame 200 can be lifted to a sufficiently high position so that the flange can pass smoothly, and then the mounting frame 200 can be lowered to continue the extension operation of the water lifting pipe 600, which can significantly improve the flexibility and adaptability of the device. Furthermore, the second connecting plate 330 is provided with a reinforcing rib 331, and the reinforcing rib 331 is used to strengthen the connection strength between the second connecting plate 330 and the base 100.

[0020] Furthermore, the clamp assembly 400 can ensure the stability of the water pipe 600 during operation, and can also quickly stop the movement of the riser in an emergency, thereby improving the safety of the construction process and protecting the integrity of the water pipe 600. Specifically, refer to Figure 2The clamp assembly 400 further includes a brake hydraulic cylinder 420, which is fixed to the lower end surface of the base 100. A clamp 430 is provided at one end of the clamp hydraulic arm 410, and the other end of the clamp hydraulic arm 410 is plugged into the brake hydraulic cylinder 420. The clamp hydraulic arm 410 can pop out along the brake hydraulic cylinder 420 so that the clamp 430 is clamped to the outer wall 610 of the water lifting pipe 600. Under the control of the brake hydraulic cylinder 420, the clamp hydraulic arm 410 in the clamp assembly 400 can be extended to clamp or release the water lifting pipe 600. When the water lifting pipe 600 needs to be fixed, the clamp hydraulic arm 410 will be extended under the drive of the brake hydraulic cylinder 420, tightly holding the outer surface of the water lifting pipe 600, ensuring that the water lifting pipe 600 will not move during operation. Furthermore, the clamp assembly 400 is electrically connected to the roller speed sensor 530. When the roller speed sensor 530 detects that the speed of the roller 510 is abnormally accelerated, it will send a signal to the brake hydraulic cylinder 420. After receiving the signal, the brake hydraulic cylinder 420 quickly drives the clamp hydraulic arm 410 to clamp the water lifting pipe 600 to prevent the water lifting pipe 600 from continuing to fall in the event of loss of control, thereby playing an emergency braking role. Furthermore, a bolt seat 431 is provided on the brake hydraulic cylinder 420, and a screw can pass through the bolt seat 431 to fix the brake hydraulic cylinder 420 to the lower end surface of the base 100, so that the brake hydraulic cylinder 420 can operate stably during the movement of the water lifting pipe 600, and the installation and disassembly of the brake hydraulic cylinder 420 can also be simple. Furthermore, the clamp 430 is made of rubber material so that the clamp 430 has a large friction coefficient and can provide sufficient friction to fix the water pumping pipe 600. At the same time, the rubber material is soft and will not damage the paint layer or other coating on the outer surface of the water pumping pipe 600, thereby avoiding scratches and wear on the outer wall 610 of the water pumping pipe 600.

[0021] Furthermore, the roller assembly 500 also includes a roller hydraulic cylinder 520 and a roller speed sensor 530. The roller hydraulic cylinder 520 is fixed to the upper end surface of the mounting frame 200, and the roller speed sensor 530 is fixed to one side of the roller hydraulic cylinder 520. The roller hydraulic cylinder 520 is provided with a retractable roller hydraulic arm 521, and the front end of the roller hydraulic arm 521 is provided with a roller shaft. The roller speed sensor 530 is connected to the roller shaft, and the roller speed sensor 530 is used to detect the rotation speed of the roller 510. The roller assembly 500 contacts the outer wall 610 of the water-lifting pipe 600 through the roller 510 thereon, so as to support and guide the water-lifting pipe 600. Specifically, the roller 510 on the roller assembly 500 can be tightly pressed against the outer surface of the water-lifting pipe 600 through the extension and contraction of the roller hydraulic arm 521, thereby providing stable support during the extension or recovery of the water-lifting pipe 600, ensuring that the water-lifting pipe 600 will not shake or deviate. Furthermore, the roller 510 is rotatably connected to the roller shaft, and a roller motor 522 is provided on the side of the roller hydraulic arm 521, and the roller motor 522 is connected to the roller shaft through a reduction gear. The roller motor 522 is connected to the roller shaft through a reduction gear, and can drive the roller 510 to rotate, thereby controlling the up and down movement of the water-lifting pipe 600, so that the water-lifting pipe 600 can be smoothly moved during the extension or recovery process, avoiding the problem of large-scale shaking of the water-lifting pipe 600 in the traditional electric hoist method. Furthermore, the exterior of the roller 510 is made of rubber material, which can ensure sufficient friction to control the movement of the water pipe 600 without damaging the coating or structure of the outer wall 610 of the water pipe 600, thereby extending the service life of the water pipe 600.
