As shown in fig. 4-5, the fixing unit 220 includes a collar 221 and a stretching piece 222, a rubber bowl rim ring 224 is fixedly connected under the stretching piece 222, a hole is designed in the middle of the rubber bowl rim ring 224, the rubber bowl rim ring 224 passes through the connecting conduit 210, the fixing unit 220 has a degree of freedom of movement along the outer surface of the connecting conduit 210, a limiting ring 230 is designed at the lowest part of the connecting conduit 210, the diameter of the limiting ring 230 is larger than that of the fixing unit 220, when the connecting conduit 210 is placed in the positioning conduit 340 downwards, the rubber bowl rim ring 224 sleeved on the outer wall of the connecting conduit 210 is subjected to the friction force in the positioning conduit 340, the friction force acting on the rubber bowl rim ring 224 is upwards, so that the rubber bowl rim ring 224 is inwards closed to drive Zhang Gepian to close, zhang Gepian pushes the collar 221 to upwards move, and as the collar 221 has a degree of freedom of movement up and down on the outer surface of the connecting conduit 210, the pushing force generated by inwards closing Zhang Gepian is not limited, the connecting conduit 210 can be easily placed in the positioning conduit 340, and after the limiting ring 230 is limited by the limiting plate 341.
As shown in fig. 6 to 8, when a worker installs the upper platform part 1, since the fixing tube 110 is provided under the platform part 1 with the same inner diameter as the connecting tube 210 and the same outer diameter as the positioning tube 340, the fixing tube 110 is nested with the connecting tube 210, and simultaneously has a downward pressure on the fixing unit 220 outside the connecting tube 210, so that the fixing unit 220 is moved downward, and stops when encountering the stop collar 230, at this time, the platform part 1 continues to apply the downward pressure on the fixing unit 220, and since the collars 221 in the fixing unit 220 are connected by the springs 223, the collars 221 have a degree of freedom of approaching each other, the downward pressure between the collars 221 causes the Zhang Gepian 222 hinged on the extension of the collars 221 to open outwards, and the rubber bowl rim 224 fixedly connected under the opening and closing piece 222 is tightly attached to the inner wall of the positioning tube 340, and the connection between the connecting tube 210 and the positioning tube 340 is completed by the pressure of the platform itself and the friction force of the inner wall of the rubber bowl rim 224 and the positioning tube 340, so that the cost is reduced, the connection process is reduced, the manufacturing and the installation is facilitated, and the rapid assembly of the platform is facilitated at sea; when the platform needs to be quickly removed, the platform part 1 is removed in sequence, when the platform part 1 leaves the positioning guide pipe 340, the pressure on the upper surface of the fixing unit 220 is small, the springs 223 between the lantern rings 221 are restored, the fixing unit 220 is pushed upwards, the opening and closing pieces 222 in the fixing unit 220 are moved upwards, the lower rubber bowl rim ring 224 is restored, the friction force between the connecting guide pipe 210 and the positioning guide pipe 340 is eliminated, the connecting guide pipe 210 can be easily taken out, and the disassembly difficulty is reduced.
As shown in fig. 9-10, because the drilling platform is positioned on the sea surface, the geological conditions of the seabed are complex and changeable, so that the geological structure balance of the drilling platform in the operation process is difficult to ensure, the stability problem is further aggravated, the stability is easily influenced by natural factors such as sea waves, wind power and the like, and the operation risk is increased; and because this equipment is the drilling platform of sea, consequently platform part 1 is equipped with the required drilling equipment of operation, and drilling equipment can produce the vibration at the during operation, and the vibration can produce the influence to offshore drilling platform's overall structure, and long-term vibration can lead to the fatigue damage of platform structure to reduce the overall stability and the security of platform. Therefore, the detachable split drilling platform is fixed between the connecting guide pipe 210 and the positioning guide pipe 340 by using the friction force of the rubber material, and can be completely attached to the inner wall of the positioning guide pipe 340 due to softer rubber material, even if the surface of the inner wall of the positioning guide pipe 340 is uneven due to processing or long-term abrasion, gaps are not generated between the positioning guide pipe 340 and the connecting guide pipe 210 of the platform, so that looseness between parts is avoided, and the whole device is more stable; secondly, because the invention is a drilling platform, the drilling equipment required by the operation of the detachable drilling platform is arranged above the platform part 1, when the drilling equipment operates, the equipment can vibrate, the vibration moves downwards along the platform from a longitudinal wave form, the connection between the whole device can be influenced, the rubber material has a vibration reduction effect, the mechanical vibration energy can be effectively absorbed and consumed by utilizing the viscoelasticity and damping characteristic of the rubber material, the resonance frequency of a vibration reduction system can be reduced, the structural damage and vibration amplification phenomenon caused by resonance can be reduced, the vibration amplitude and frequency of the structure can be reduced, the vibration amplitude transmitted to the inside of the positioning guide pipe 340 by the connecting guide pipe 210 can be obviously reduced, the vibration influence on the lower base 3 below can be reduced, and the structure is more stable.
