Description

Technical Field

[0001] This utility model relates to the field of marine drilling riser detection technology, specifically a traction device for marine drilling riser detection. Background Technology

[0002] Offshore drilling risers are indispensable key equipment in offshore oil exploration and development. Their main functions include effectively isolating seawater from drilling equipment or fluids underwater to ensure that drilling operations are not affected by seawater; circulating fluids during drilling to maintain the stability and efficiency of drilling operations; and supporting and connecting various control pipelines to ensure the integrity and safety of the drilling system.

[0003] With the continuous development of offshore oil exploration and development technologies, deepwater drilling has become one of the important methods of oil extraction. However, the complex and variable deepwater environment places extremely high demands on the safety and reliability of drilling equipment. As a crucial component of the drilling system, the performance of the offshore drilling riser directly affects the safety and efficiency of drilling operations. Therefore, conducting a comprehensive inspection of the riser before commissioning is a key step to ensure the smooth progress of drilling operations.

[0004] Because riser pipes vary in size, weight, and shape across different offshore drilling projects, existing traction devices may not be suitable for all pipe sizes. This could necessitate the use of specialized traction devices for specific projects, increasing costs and time investment.

[0005] To address this issue, we propose a traction device for inspecting risers in marine drilling. Utility Model Content

[0006] The purpose of this invention is to provide a traction device for testing marine drilling riser pipes, in order to solve the problem that existing traction devices mentioned in the background art may not be able to adapt to pipes of all specifications.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a traction device for testing marine drilling riser pipes, comprising a workbench and a main support platform and a secondary support platform disposed above the workbench, wherein the main support platform and the secondary support platform are connected by a traction structure, and a clamping mechanism is provided on the main support platform;

[0008] The clamping mechanism includes a left clamping unit and a right clamping unit;

[0009] The left clamping unit includes a slide groove, a cylinder, and a clamping plate. The two slide grooves are respectively opened on one side of the main support platform. The cylinder is set inside the slide groove. The output end of the cylinder is connected to a slider. The upper surface of the slider is fixedly connected to the bottom of the clamping plate.

[0010] Preferably, the left clamping unit and the right clamping unit have the same structure and are respectively set on both sides of the upper surface of the main support platform, which ensures the symmetry and balance of the clamping mechanism, can clamp the water-proof conduit evenly and stably, prevents deviation or shaking during inspection or transportation, and improves safety and stability.

[0011] Preferably, the main support platform and the auxiliary support platform have the same structure and both have a placement groove in the middle. The placement groove in the middle can be used to place a water-proof conduit to prevent movement.

[0012] Preferably, the traction structure includes a motor, a support plate, a first connecting seat, a threaded rod, and a second connecting seat. The back of the first connecting seat is fixedly connected to the front of the main support platform, and the back of the second connecting seat is fixedly connected to the front of the secondary support platform. The left end of the threaded rod is connected to the right side of the first connecting seat, and the right end of the threaded rod is connected to the inside of the second connecting seat. The output end of the motor is connected to the left end of the threaded rod via a coupling. The upper surface of the support plate is fixedly connected to the bottom of the motor. Driven by the motor, the traction structure causes the threaded rod to rotate, thereby driving the secondary support platform to move linearly relative to the main support platform, achieving precise traction and positioning.

[0013] Preferably, the front and back of the workbench are respectively fixedly connected to slide rods, the inner side of the slide rods is connected to a fixing block, and the outer side of the fixing block is provided with a corresponding slide rod groove. The design of the slide rods and slide rod grooves provides a stable sliding track for the main support platform and the secondary support platform, ensuring the smoothness and straightness during the traction process.

[0014] Preferably, angle steel is welded to the inner sides of the main support platform and the secondary support platform. Roller 1 and Roller 2 are respectively connected to both sides of the angle steel via bolts and threads. Roller 1 and Roller 2 are slidably connected to the slide rod. This combination of angle steel and rollers effectively reduces friction between the platform and the slide rod, making the platform slide more smoothly and reducing energy consumption and noise. At the same time, the detachable design of the rollers facilitates maintenance and replacement, improving the service life of the device.

[0015] Preferably, there are two sets of angle steel, roller one, and roller two, which are respectively arranged in pairs inside the main support platform and the auxiliary support platform. The design of the two sets of angle steel and rollers further enhances the stability and load-bearing capacity of the platform, enabling the device to carry heavier water-tight conduits for testing. At the same time, this symmetrical design also ensures the balance of the platform during sliding, avoiding swaying or tilting caused by uneven loading.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This traction device for inspecting marine drilling risers uses a motor-driven threaded rod rotation mechanism to drive the auxiliary support platform to perform precise linear motion relative to the main support platform. This achieves precise traction and positioning of the riser, improving the accuracy and efficiency of inspection or transportation.

[0018] 2. The traction device for inspecting the riser in marine drilling features a design combining angle steel and rollers on the inner sides of the main and auxiliary support platforms. This effectively reduces friction between the platform and the sliding rod, resulting in smoother platform sliding. This not only reduces energy consumption and noise but also extends the equipment's service life. The detachable design of the rollers also facilitates maintenance and replacement, improving the equipment's maintainability.

[0019] 3. The traction device for inspecting the riser in marine drilling, with its two sets of angle steel and rollers, not only enhances the stability and load-bearing capacity of the platform, enabling the device to carry heavier risers for inspection, but also ensures the balance of the platform during sliding through a symmetrical design, avoiding swaying or tilting caused by uneven loading, and further improving the overall safety and stability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4This utility model provides a technical solution: Example

[0027] A traction device for testing a marine drilling riser includes a workbench 1 and a main support platform 2 and a secondary support platform 3 disposed above the workbench 1. The main support platform 2 and the secondary support platform 3 are connected by a traction structure. A clamping mechanism is provided on the main support platform 2.

[0028] The clamping mechanism includes a left clamping unit and a right clamping unit;

[0029] The left clamping unit includes a slide groove 201, a cylinder 203, and a clamping plate 204. Two slide grooves 201 are respectively located on one side of the main support platform. The cylinder 203 is located inside the slide groove 201, and its output end is connected to a slider. The upper surface of the slider is fixedly connected to the bottom of the clamping plate 204. The cylinder 203 drives the clamping plate 204 to move via the slider, achieving rapid and stable clamping of the water-tight conduit and preventing it from falling off or shaking during inspection or transportation. The left and right clamping units have the same structure and are respectively located on both sides of the upper surface of the main support platform 2. The main support platform 2 and the auxiliary support platform 3 have the same structure and both have a placement slot 202 in the middle for placing the water-tight conduit, preventing it from moving during inspection or transportation, and improving the accuracy and safety of the inspection. Example

[0030] Based on Embodiment 1, the traction structure includes a motor 401, a support plate 402, a first connecting seat 403, a threaded rod 404, and a second connecting seat 405. The back of the first connecting seat 403 is fixedly connected to the front of the main support platform 2, and the back of the second connecting seat 405 is fixedly connected to the front of the secondary support platform 3. The left end of the threaded rod 404 is connected to the right side of the first connecting seat 403, and the right end of the threaded rod 404 is connected to the inside of the second connecting seat 405. The output end of the motor 401 is connected to the left end of the threaded rod 404 via a coupling. The upper surface of the support plate 402 is fixedly connected to the bottom of the motor 401. Slide rods 5 are fixedly connected to the front and back of the worktable 1, respectively. A fixing block 101 is connected to the inner side of the slide rod 5, and a corresponding slide rod groove is opened on the outer side of the fixing block 101. The motor 401 drives the threaded rod 404 to rotate via the coupling, causing the secondary support platform 3 to move linearly relative to the main support platform 2, thereby achieving precise traction and positioning of the water-tight conduit. Angle steel 601 is welded to the inner sides of the main support platform 2 and the auxiliary support platform 3. Rollers 602 and 603 are bolted to both sides of the angle steel 601. Rollers 602 and 603 are slidably connected to the slide rod 5. The slide rod 5 and the fixing block 101 provide a stable sliding track for the main support platform 2 and the auxiliary support platform 3, ensuring smoothness and straightness during traction. There are two sets of angle steel 601, rollers 602 and 603. The roller design effectively reduces friction between the platform and the slide rod, making the platform slide smoother and reducing energy consumption and noise. The rollers are arranged in pairs on the inner sides of the main support platform 2 and the auxiliary support platform 3. The two sets of rollers further enhance the stability and load-bearing capacity of the platform, enabling the device to carry heavier water-tight conduits for testing.

[0031] Working principle: Place the workbench 1 on a stable surface, ensuring all components are securely installed. Place the water-proof conduit into the placement slot 202 of the auxiliary support platform 3. Activate the cylinder 203 to drive the clamping plate 204 towards the water-proof conduit until it firmly grips it. Check the clamping stability to ensure the water-proof conduit will not fall off or shake during testing or transportation.

[0032] The motor 401 is started, driving the threaded rod 404 to rotate via the coupling, which in turn causes the auxiliary support platform 3 to move linearly relative to the main support platform 2. The speed and direction of the motor 401 can be adjusted as needed to achieve precise traction and positioning of the waterproof conduit. During the traction process, the waterproof conduit can be inspected or transported as required.
