[0031] Example

[0032] See Figure 1 A lifting and locking device includes a lifting device 1 and a locking device 2. The lifting device 1 connects the platform body and the pile leg 3. The lifting device 1 includes a driving mechanism 1.1 and a transmission mechanism 1.2. The driving mechanism 1.1 is disposed inside the platform body. The transmission mechanism 1.2 connects the driving mechanism 1.1 and the pile leg 3. The driving mechanism 1.1 drives the platform body and / or the pile leg 3 to move vertically up and down through the transmission mechanism 1.2.

[0033] See Figure 2The drive mechanism 1.1 includes a servo motor 1.1.1 and a reducer 1.1.2, both of which are fixed inside the platform body. The output end of the servo motor 1.1.1 is connected to the input end of the reducer 1.1.2. The transmission mechanism 1.2 includes a gear 1.2.1 and a rack 1.2.2. The gear 1.2.1 is connected to the output end of the reducer 1.1.2, and the rack 1.2.2 is disposed on the outer side of the pile leg 3 along the height direction of the pile leg 3. In this embodiment, the rack 1.2.2 is detachably connected to the outer side of the pile leg 3 in segments for easy maintenance and replacement.

[0034] In this embodiment, a servo motor 1.1.1 is used as the power source, and a reducer 1.1.2 is used to increase the torque, which drives the gear 1.2.1 to rotate. The gear 1.2.1 meshes with the rack and pinion 1.2.2 to realize the lifting and lowering of the platform body / leg 3. In this embodiment, the gear 1.2.1 needs to be hardened during manufacturing to improve its strength and wear resistance.

[0035] In this embodiment, see Figure 3 The locking device 2 is located inside the platform body. The locking device 2 includes a driving part 2.1 and a locking part 2.2. The driving part 2.1 is connected to the locking part 2.2. The driving part 2.1 drives the locking part 2.2 to lock and unlock the platform body and the pile leg 3.

[0036] Specifically, the drive unit 2.1 includes two drive components, upper and lower, and a locking part 2.2 is connected between the two drive components. The two drive components drive the locking part 2.2 to engage and lock the pin rack 1.2.2.

[0037] The driving unit includes a driving motor 2.1.1. In this embodiment, preferably, each driving unit includes two driving motors 2.1.1. The output end of the driving motor 2.1.1 is connected to a lead screw 2.1.2. The lead screw 2.1.2 is connected to the locking part 2.2.

[0038] See Figure 3 The locking part 2.2 includes an upper wedge 2.2.1 and a lower wedge 2.2.2. The upper wedge 2.2.1 is connected to the upper drive unit, and the lower wedge 2.2.2 is connected to the lower drive unit. A locking block 2.2.3 is slidably connected between the upper wedge 2.2.1 and the lower wedge 2.2.2.

[0039] The locking block 2.2.3 has a conical structure, and its bottom surface is parallel to the height direction of the pile leg 3. The upper wedge 2.2.1 and the lower wedge 2.2.2 are slidably connected to the two sides of the locking block 2.2.3, respectively. In this embodiment, the upper wedge 2.2.1 and the lower wedge 2.2.2 are both T-shaped structures. The T-shaped structure includes a horizontal connecting part and a vertical connecting part. The horizontal connecting part is connected to the lead screw 2.1.2. An adjusting nut 5 is provided between the end of the lead screw 2.1.2 away from the drive motor 2.1.1 and the horizontal connecting part. The drive motor 2.1.1 drives the lead screw 2.1.2 to rotate, thereby driving the adjusting nut 5 to move up and down along the lead screw 2.1.2, thereby driving the upper wedge 2.2.1 and the lower wedge 2.2.2 to move up and down.

[0040] In this embodiment, the vertical connecting part is slidably connected to the locking block 2.2.3. The vertical connecting part is provided with a slider with a groove. The two sides of the locking block 2.2.3 are provided with protrusions corresponding to the groove positions. The groove and the protrusion cooperate to achieve relative sliding.

[0041] In this embodiment, the bottom surface of the locking block 2.2.3 is provided with a groove 2.2.3.1 that matches the pin teeth on the pin rack 1.2.2. The opening of the groove 2.2.3.1 is chamfered to facilitate the pin teeth to be engaged in the groove 2.2.3.1.

[0042] Specifically, when it is necessary to lock the platform body and the pile leg 3, the drive motors 2.1.1 of the upper and lower drive units drive the lead screw 2.1.2 to rotate, thereby causing the upper wedge block 2.2.1 and the lower wedge block 2.2.2 to move closer together, which in turn pushes the locking block 2.2.3 closer to the pin rack 1.2.2 and engages with the pin teeth, thereby locking the platform body and the pile leg 3; when it is necessary to unlock the platform body and the pile leg 3, the opposite operation is performed.

[0043] In this embodiment, a guiding device 4 is also included. The guiding device 4 is disposed inside the platform body and is used to guide the vertical lifting and lowering of the platform body. Preferably, the guiding device includes a plurality of guide wheels disposed inside the platform body, and the pile legs 3 are correspondingly provided with guide grooves. The guide wheels slide along the guide grooves to achieve the guiding function for the vertical lifting and lowering of the platform body.

[0044] This embodiment also provides an offshore platform, including multiple legs 3 and a platform body. A lifting and locking device, as described above, is provided between the legs 3 and the platform body. The lifting and locking device is used to realize the vertical lifting and lowering of the platform body and / or the legs 3, as well as locking and unlocking between the platform body and the legs 3. Preferably, at least two sets of lifting devices and at least two sets of locking devices are symmetrically arranged between a single leg 3 and the platform body.

[0045] In practical applications:

[0046] When the platform body needs to rise, the drive mechanism 1.1 drives the gear 1.2.1 to rotate counterclockwise. The gear 1.2.1 meshes with the pin teeth, causing the pile leg 3 to descend. After the pile leg 3 touches the bottom and stabilizes, the drive mechanism 1.1 continues to work, and at this time the platform body rises along the pile leg 3.

[0047] When the platform body rises to the designated position, the locking device 2 starts to work, the drive motor 2.1.1 drives the lead screw 2.1.2 to rotate, causing the upper wedge block 2.2.1 and the lower wedge block 2.2.2 to move closer together, thereby pushing the locking block 2.2.3 to approach the pin rack 1.2.2 and engage with the pin, thus locking the platform body and the pile leg 3.

[0048] When the platform body needs to be lowered, the lock between the platform body and the pile leg 3 is released, and the drive mechanism 1.1 drives the gear 1.2.1 to rotate clockwise. The gear 1.2.1 meshes with the pin tooth, driving the platform body to descend along the pile leg 3. After the platform body floats on the sea surface, the drive mechanism 1.1 continues to work, and the pile leg 3 rises.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
