Description

Technical Field

[0001] This utility model relates to the field of drilling platform technology, specifically to a single-cylinder driven steering combustion arm. Background Technology

[0002] In the operation of semi-submersible oil drilling platforms, traditional combustion boom steering systems mostly employ multi-cylinder drives or complex mechanical transmission structures. While multi-cylinder drive systems can achieve combustion boom steering, they have several drawbacks. Firstly, the use of multiple cylinders makes the entire system structure extremely complex, increasing manufacturing and installation costs. Furthermore, due to the large number of components, the coordinated control between cylinders is difficult, easily leading to synchronization errors and unstable combustion boom steering, affecting operational safety. Secondly, the complex structure makes maintenance extremely cumbersome, requiring significant manpower and material resources, and frequent maintenance increases platform downtime, reducing operational efficiency. Steering systems based on complex mechanical transmission structures also suffer from problems such as easy wear of transmission components, high failure rates, and slow response speeds, making it difficult to meet the requirements of rapid and precise combustion boom steering for semi-submersible oil drilling platforms.

[0003] On semi-submersible oil drilling platforms, the combustion boom, as a crucial piece of equipment, plays a vital role in safely handling excess combustible gases generated during extraction. With the continuous expansion of offshore oil extraction and the increasing complexity of the operating environment, higher demands are placed on the performance and flexibility of the combustion boom. Especially under certain specific operating conditions, the combustion boom needs to be able to perform significant turns, such as 180°, to adapt to different wind directions, changes in platform layout, and the operational needs of surrounding equipment.

[0004] Now, a novel single-cylinder driven steering combustion arm is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a single-cylinder driven steering combustion arm to solve the problem of complex and difficult maintenance of multi-cylinder structures mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a single-cylinder driven steering combustion arm, comprising a fixed base, a slewing support at the top of the fixed base, a rotating base at the top of the slewing support, a boom above the rotating base, a flange mounting seat fixedly connected to the rear end of the top of the rotating base, a connecting flange movably connected to the top of the flange mounting seat, a cylinder mounting seat fixedly connected to the left side of the front end of the top of the rotating base, and a single-cylinder driven steering assembly at the top of the rotating base.

[0007] The steering assembly includes a rotary power cylinder, which is movably connected to the rear end of the cylinder mounting base. A connecting crank is movably connected to the top of the connecting flange. A connecting pin is vertically inserted into the top of the boom. The top of the connecting flange is sequentially provided with a first positioning hole, a second positioning hole, a third positioning hole, a fourth positioning hole, and a fifth positioning hole.

[0008] As a further technical solution of this utility model, the output end of the rotary power cylinder is movably connected to the connecting crank, and the bottom end of the rotary power cylinder is higher than the top end of the rotating base.

[0009] As a further technical solution of this utility model, the connecting pin passes through the boom and extends into the interior of the connecting flange, and the boom and the connecting flange are fixedly connected by the connecting pin.

[0010] As a further technical solution of this utility model, the first positioning hole, the second positioning hole, the third positioning hole, the fourth positioning hole, and the fifth positioning hole have the same diameter, and the first positioning hole, the second positioning hole, the third positioning hole, the fourth positioning hole, and the fifth positioning hole pass through the upper and lower ends of the connecting flange.

[0011] As a further technical solution of this utility model, the bottom end of the connecting crank and the top end of the connecting flange are fitted together, and the connecting crank and the connecting flange are movably connected by bolts.

[0012] As a further technical solution of this utility model, the connecting bolt between the connecting crank and the connecting flange can be driven into one of the first positioning hole, the second positioning hole, the third positioning hole, the fourth positioning hole, and the fifth positioning hole, respectively. The first positioning hole, the second positioning hole, the third positioning hole, the fourth positioning hole, and the fifth positioning hole correspond to 45°, 90°, 135°, 150°, and 180°.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the single-cylinder driven steering combustion arm not only realizes the function of single-cylinder driven steering, but also realizes the function of adjustable steering range;

[0014] (1) By setting a rotary power cylinder, boom, connecting crank, connecting flange and connecting pin, the combustion boom is fixed on the boom when in use. When the combustion boom needs to be turned, the piston inside the rotary power cylinder moves in extension and retraction under the action of hydraulic oil. The pressure of hydraulic oil pushes the piston, thereby generating thrust or pull to drive the boom to rotate. The extension and retraction of the piston is transmitted to the connecting flange through the connecting crank. Since the boom and the connecting flange are fixedly connected by the connecting pin, the boom and the connecting flange rotate synchronously under the action of the rotary power cylinder, thereby realizing the turning action of the combustion boom. By controlling the extension and retraction amount and extension speed of the rotary power cylinder, the rotation angle and rotation speed of the combustion boom can be precisely controlled to meet the usage requirements of the offshore semi-submersible oil drilling platform under different working conditions. The combustion boom is driven to turn by a single cylinder, which has a simple structure and low maintenance cost, and realizes the function of single cylinder driving steering.

[0015] (2) By providing a connecting flange, a first positioning hole, a second positioning hole, a third positioning hole, a fourth positioning hole and a fifth positioning hole, the rotary power cylinder is connected to the connecting crank and the connecting flange during use. The connecting bolts are selected according to the corresponding positioning holes as needed. The first positioning hole, the second positioning hole, the third positioning hole, the fourth positioning hole and the fifth positioning hole correspond to 45°, 90°, 135°, 150° and 180° respectively, realizing the function of adjustable steering range.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example: Please refer to Figures 1-4 A single-cylinder driven steering combustion arm includes a fixed base 1, a slewing support 2 at the top of the fixed base 1, a rotating base 3 at the top of the slewing support 2, a boom 5 above the rotating base 3, a flange mounting seat 9 fixedly connected to the rear end of the top of the rotating base 3, a connecting flange 7 movably connected to the top of the flange mounting seat 9, a cylinder mounting seat 10 fixedly connected to the left side of the front end of the top of the rotating base 3, and a single-cylinder driven steering assembly at the top of the rotating base 3.

[0023] Please see Figures 1-4 A single-cylinder driven steering combustion arm also includes a steering assembly, which includes a rotary power cylinder 4. The rotary power cylinder 4 is movably connected to the rear end of the cylinder mounting seat 10. A connecting crank 6 is movably connected to the top of the connecting flange 7. A connecting pin 8 is vertically inserted into the top of the boom 5. The top of the connecting flange 7 is sequentially provided with a first positioning hole 11, a second positioning hole 12, a third positioning hole 13, a fourth positioning hole 14, and a fifth positioning hole 15.

[0024] The output end of the rotary power cylinder 4 is movably connected to the connecting crank 6. The bottom end of the rotary power cylinder 4 is higher than the top end of the rotary base 3. The connecting pin 8 passes through the boom 5 and extends into the interior of the connecting flange 7. The boom 5 and the connecting flange 7 are fixedly connected by the connecting pin 8. The bottom end of the connecting crank 6 and the top end of the connecting flange 7 are in contact. The connecting crank 6 and the connecting flange 7 are movably connected by bolts. The combustion arm is driven to turn by a single cylinder. The structure is simple and the maintenance cost is low.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the piston inside the rotary hydraulic cylinder 4 extends and retracts under the action of hydraulic oil. The pressure of the hydraulic oil pushes the piston, thereby generating thrust or pull to drive the boom 5 to rotate. The extension and retraction of the piston is transmitted to the connecting flange 7 through the connecting crank 6. Since the boom 5 and the connecting flange 7 are fixedly connected by the connecting pin 8, the boom 5 and the connecting flange 7 rotate synchronously under the force of the rotary hydraulic cylinder 4, thereby realizing the steering action of the combustion boom. By controlling the extension and retraction amount and speed of the rotary hydraulic cylinder 4, the rotation angle and rotation speed of the combustion boom can be precisely controlled to meet the usage requirements of the offshore semi-submersible oil drilling platform under different working conditions.

[0026] The first positioning hole 11, the second positioning hole 12, the third positioning hole 13, the fourth positioning hole 14, and the fifth positioning hole 15 have the same diameter. The first positioning hole 11, the second positioning hole 12, the third positioning hole 13, the fourth positioning hole 14, and the fifth positioning hole 15 pass through the upper and lower ends of the connecting flange 7. The connecting bolts between the connecting crank 6 and the connecting flange 7 can be driven into one of the first positioning holes 11, the second positioning hole 12, the third positioning hole 13, the fourth positioning hole 14, and the fifth positioning hole 15. The first positioning hole 11, the second positioning hole 12, the third positioning hole 13, the fourth positioning hole 14, and the fifth positioning hole 15 correspond to 45°, 90°, 135°, 150°, and 180° respectively, which facilitates limiting the steering range.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the rotary power cylinder 4 is connected to the connecting crank 6 and the connecting flange 7. The connecting bolts are selected according to the corresponding positioning holes as needed. The first positioning hole 11, the second positioning hole 12, the third positioning hole 13, the fourth positioning hole 14, and the fifth positioning hole 15 correspond to 45°, 90°, 135°, 150°, and 180°, respectively.

[0028] Working Principle: In use, the combustion boom is first fixed to the boom 5. When the combustion boom needs to be turned, the piston inside the rotary power cylinder 4 extends and retracts under the action of hydraulic oil. The pressure of the hydraulic oil pushes the piston, thereby generating thrust or pull to drive the boom 5 to rotate. The extension and retraction of the piston is transmitted to the connecting flange 7 through the connecting crank 6. Since the boom 5 and the connecting flange 7 are fixedly connected by the connecting pin 8, the boom 5 and the connecting flange 7 rotate synchronously under the force of the rotary power cylinder 4, thereby realizing the turning action of the combustion boom. By controlling the extension and retraction amount and speed of the rotary power cylinder 4, the rotation angle and rotation speed of the combustion boom can be precisely controlled to meet the usage requirements of the offshore semi-submersible oil drilling platform under different working conditions. The rotary power cylinder 4 is connected to the connecting crank 6 and the connecting flange 7. The connecting bolts are selected according to the corresponding positioning holes as needed. The first positioning hole 11, the second positioning hole 12, the third positioning hole 13, the fourth positioning hole 14, and the fifth positioning hole 15 correspond to 45°, 90°, 135°, 150°, and 180°, respectively.
