Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering, in particular to a novel offshore unmanned platform boarding device. Background Art

[0002] At present, offshore oilfield groups are gradually promoting the intelligent transformation of unmanned platforms. In the subsequent daily production, unmanned platforms will no longer be assigned personnel for duty. They only need to rely on the central platform for monitoring, and regularly inspect and operate the unmanned platforms. As a result, the demand for personnel to board unmanned platforms has increased significantly compared with before. The current wellhead platform boarding devices are mainly suspension bridge winches and soft ladders. After optimization and transformation, some platforms can use rope climbing machines to achieve boarding. However, in actual use, it is found that both the soft ladder and the rope climbing machine have certain restrictions when the sea conditions and weather are poor. On the one hand, the suspension bridge is limited in length, generally only about 10 meters in length, and it is difficult for ships to dock, especially in strong winds and waves. The control requirements for ships are higher, and the platform will collide with the platform if you are not careful. On the other hand, the operation and control technology requirements of the soft ladder and the rope climbing machine are high, and the boarding is difficult. In addition, multiple people are required to control and cooperate during the shaking of the ship. If you cannot board the platform within the short time window of the ship's docking, it will also cause the personnel to face the safety risks of falling and bruising. If you fail to board the platform in time, it will have a certain impact on production safety and work efficiency. Summary of the invention

[0003] The purpose of the utility model is to provide a new type of offshore unmanned platform boarding device, which improves the safety, reliability and efficiency of operators boarding the offshore unmanned platform, and also avoids the risk of collision between the ship and the offshore unmanned platform due to being too close to the platform.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A new type of offshore unmanned platform boarding device includes a working platform, a manned seat and a lifting mechanism. The working platform and the manned seat are connected by the lifting mechanism. The lifting mechanism is configured to drive the manned seat close to or away from the surface of the working platform.

[0007] Furthermore, a support plate extending outward is provided on the side of the working platform, and the swing arm is pressed against the upper surface of the support plate.

[0012] Furthermore, a locking nut is threadedly connected to the top end of the fixed shaft, and the locking nut is pressed against the wall surface of the swing arm.

[0013] Furthermore, a fence is provided on the working platform.

[0018] The technical solutions in the embodiments of the present utility model will be described below in conjunction with the accompanying drawings.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a new type of offshore unmanned platform boarding device includes a working platform 1, a manned seat 2 and a lifting mechanism, wherein the working platform 1 and the manned seat 2 are connected via the lifting mechanism, and the lifting mechanism is configured to be able to drive the manned seat 2 to approach or move away from the surface of the working platform 1, and the lifting mechanism includes a fixed shaft 3, a swing arm 4, a first telescopic arm 5, a second telescopic arm 6, and a hydraulic station 7, one end of the swing arm 4 is rotatably set on the working platform 1 via the fixed shaft 3, the other end of the swing arm 4 is connected to the manned seat 2 via the first telescopic arm 5, the swing arm 4 is vertically set to the first telescopic arm 5, one end of the second telescopic arm 6 is hingedly set on the working platform 1, and the other end of the second telescopic arm 6 is hingedly set on the swing arm 4, and the hydraulic station 7 is set on the working platform 1, and is used to control the extension and retraction of the first telescopic arm 5 and the second telescopic arm 6.

[0020] In this embodiment, after the ship docks at the work platform 1, the operator can remotely control the hydraulic station 7, and the hydraulic station 7 drives the extension of the first telescopic arm 5 and the second telescopic arm 6. The swing arm 4 rotates around the fixed axis 3 driven by the second telescopic arm 6, and moves the manned seat 2 horizontally outward, and the manned seat 2 moves downward driven by the first telescopic arm 5, and finally moves the manned seat 2 to the ship. After the operator sits on the manned seat 2, the first telescopic arm 5 and the second telescopic arm 6 are driven to retract, and the manned seat 2 returns to its original position, so that the operator can board the work platform 1. Compared with the prior art, in weather conditions with strong winds and waves, the present device not only prevents the operator from facing the risk of falling or bruising when boarding the work platform 1, but also can quickly transfer the operator to the work platform 1, thereby ensuring the timeliness, safety and efficiency of unmanned platform maintenance of offshore oilfields.

[0021] It should be noted that the device moves the manned seat 2 horizontally outward via the swing arm 4 so that the manned seat 2 is moved to the ship, thereby making it unnecessary for the ship to be moored too close to the work platform 1, thereby enabling the transfer of operating personnel and effectively avoiding the risk of collision between the ship and the work platform 1.

[0022] The swing arm 4 and the first telescopic arm 5 are hingedly arranged, and a third telescopic arm 8 controlled by a hydraulic station 7 is arranged at the angle between the swing arm 4 and the first telescopic arm 5. One end of the third telescopic arm 8 is hingedly arranged on the wall of the swing arm 4, and the other end of the third telescopic arm 8 is hingedly arranged on the side of the first telescopic arm 5. The first telescopic arm 5 can be folded and stored by the third telescopic arm 8, so that the first telescopic arm fits the swing arm 4, avoiding the bending and deformation of the first telescopic arm 5 due to the continuous blowing of the strong wind at sea. At the same time, when the platform boarding operation is required, the two ends of the third telescopic arm 8 will respectively resist the swing arm 4 and the first telescopic arm 5, ensuring that the swing arm 4 and the first telescopic arm 5 are continuously in a mutually perpendicular state.

[0023] The side of the working platform 1 is provided with a support plate 9 extending outward, and the swing arm 4 is pressed against the upper surface of the support plate 9. The support plate 8 supports the swing arm 4, realizes the effect of sharing the load, and prolongs the service life of the swing arm 4.

[0024] The wall surface of the swing arm 4 and the upper surface of the support plate 9 are rollingly matched through the guide wheel assembly 10. The guide wheel assembly 10 can reduce the friction between the swing arm 4 and the support plate 9, ensuring that the swing arm 4 can reciprocate smoothly.

[0025] The support plate 9 includes a horizontal section 9a and an inclined section 9b, one side of the horizontal section 9a is located on the side of the working platform 1, and the inclined section 9b is arranged on the other side of the horizontal section 9a, and the inclined section 9b is arranged to be inclined downward. When the swing arm 4 rotates and returns to the support plate 9, even if the other end of the swing arm 4 bends downward due to the load, it can be lifted and moved upward by the inclined section 9b of the support plate 9 until it reaches the horizontal section 9a of the support plate 9, thereby realizing the position return of the swing arm 4 and ensuring the normal support of the support plate 9.

[0026] The first telescopic arm 5 is hinged to the passenger seat 2. After the first telescopic arm 5 is folded and stored, the hinged design enables the passenger seat 2 to sag under the action of gravity, thereby reducing the load on the end of the first telescopic arm 5.

[0027] The side of the working platform 1 is provided with an auxiliary platform 11 extending horizontally outward, the surface height of the working platform 1 is greater than the surface height of the auxiliary platform 11, the surface of the working platform 1 and the surface of the auxiliary platform 11 are connected by a ladder 12, and the projection surface of the movement trajectory of the manned seat 2 partially overlaps with the projection surface of the auxiliary platform 11. The surface height of the auxiliary platform 11 is lower than the surface height of the working platform 1. In the case of strong winds and waves, the operator can quickly reach the auxiliary platform 11 through the manned seat 2, and then climb to the surface of the working platform 1 via the ladder 12, so as to avoid the collision of wind and waves and ships with the manned seat 2 due to strong winds and waves, and prevent equipment damage and operator injuries.

[0028] The top end of the fixed shaft 3 is threadedly connected with a locking nut 13, and the locking nut 13 is pressed against the wall surface of the swing arm 4. By rotating the locking nut 13, the degree of compression of the locking nut 13 on the swing arm 4 can be adjusted, thereby ensuring the installation stability of the swing arm 4 on the fixed shaft 3 and improving the stability and accuracy of the rotation of the swing arm 4.

[0029] The working platform 1 is provided with a fence 14. The fence 14 can play a role of safety protection to prevent the operators on the working platform 1 from accidentally falling into the water.
