Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to a lock for hoisting skirt pile diaphragms. Background Technology

[0002] In the field of offshore oil and gas development, jacket structures are common offshore equipment platforms. Large jacket structures are typically fixed to the seabed using skirt pile foundations, with a skirt pile diaphragm sealing the top of the skirt pile sleeve to increase reserve buoyancy and assist in the launching and righting installation of the jacket structure. Therefore, ensuring the integrity and sealing of the skirt pile diaphragm is crucial during the construction and installation phase. In existing technologies, when hoisting the skirt pile diaphragm, ropes are generally used to wrap and bind the diaphragm, then the ropes are gathered together and connected to the crane hook. After hoisting into place, the ropes need to be disassembled, making the operation cumbersome and inconvenient for hoisting work. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a locking device for lifting the diaphragm of the skirt pile, which can conveniently and quickly lock or remove the diaphragm of the skirt pile, so as to facilitate the rapid, safe and reliable lifting operation.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A lock for lifting skirt pile diaphragms includes a fixed plate, a movable plate, and a detachable pin. The fixed plate has a hook hole and a first through hole, and the movable plate has a second through hole. The movable plate is rotatably connected to the fixed plate, and an opening is formed between the movable plate and the fixed plate. When the movable plate rotates away from the fixed plate, the opening widens and can be engaged with the outer edge of the skirt pile diaphragm. When the movable plate rotates closer to the fixed plate until the first through hole and the second through hole are aligned, the opening narrows. The movable plate and the fixed plate can be combined to lock the skirt pile diaphragm. The detachable pin can be inserted into the first through hole and the second through hole to lock the movable plate and the fixed plate together.

[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: When it is necessary to lift the skirt pile diaphragm, the detachable pin can be removed, the moving plate can be rotated so that the moving plate and the fixed plate are far apart, and the opening of the lock can be widened. At this time, the opening of the lock can be inserted into the outer edge drum of the skirt pile diaphragm. Then, the moving plate is rotated in the opposite direction until the first through hole and the second through hole are aligned. The moving plate and the fixed plate can be combined and locked on both sides of the outer edge drum of the skirt pile diaphragm. At this time, the detachable pin can be inserted to lock the moving plate and the fixed plate together and fix them. Finally, the lifting buckle of the crane can be directly connected to the lifting buckle hole of the lock, and the skirt pile diaphragm can be lifted by the crane. Compared to the method of using ropes to bind the skirt diaphragm, this locking device has a simpler structure, and the crane's hook can be directly connected to the hook hole, which allows for convenient and quick locking or unlocking of the skirt diaphragm. This avoids the trouble of tangling, collecting, and dismantling ropes, while also ensuring the locking effect of the skirt diaphragm during lifting. This makes the lifting work safe and reliable. The rigid locking device acts on the outer edge of the skirt diaphragm, eliminating the need for a separate lifting structure on the skirt diaphragm, effectively preventing damage to the skirt diaphragm and ensuring its intact sealing.

[0006] The aforementioned locking device for lifting the diaphragm of the skirt post also includes a fixed pin, and the movable piece and the fixed piece are rotatably connected by the fixed pin.

[0007] The aforementioned locking device for lifting the diaphragm of the skirt pile has a first notch on the side of the fixed plate and a second notch on the side of the movable plate. When the movable plate rotates close to the fixed plate to the position where the first through hole and the second through hole are aligned, the combined hole formed by the first notch and the second notch is larger than the opening.

[0008] The aforementioned locking device for lifting the diaphragm of the skirt pile, when the moving piece rotates close to the fixed piece until the first through hole and the second through hole are aligned, the hook hole, the detachable pin, and the opening are arranged in a triangular pattern.

[0009] The aforementioned locking device for lifting the diaphragm of the skirt pile, when the moving piece rotates close to the fixed piece until the first through hole and the second through hole are aligned, the hook hole, the detachable pin, and the opening are linearly distributed.

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0015] The reference numerals are as follows: 100 fixed piece, 110 hanging hole, 120 first through hole, 130 first notch, 200 moving piece, 210 second through hole, 220 second notch, 300 detachable pin, 400 opening, 500 fixed pin. Detailed Implementation

[0016] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 4 This utility model provides a locking device for lifting a diaphragm of a skirt post, including a fixed plate 100, a movable plate 200, and a detachable pin 300. The fixed plate 100 has a hook hole 110 and a first through hole 120, and the movable plate 200 has a second through hole 210. The movable plate 200 is rotatably connected to the fixed plate 100, and an opening 400 is formed between the movable plate 200 and the fixed plate 100. When the movable plate 200 rotates away from the fixed plate 100, the locking device can be adjusted accordingly. At 0, the opening 400 is large enough to fit into the outer edge of the skirt pile diaphragm. When the moving piece 200 rotates and approaches the fixed piece 100 until the first through hole 120 and the second through hole 210 are aligned, the opening 400 becomes smaller. The moving piece 200 and the fixed piece 100 can then be combined to lock the skirt pile diaphragm. The detachable pin 300 can be inserted into the first through hole 120 and the second through hole 210 to lock the moving piece 200 and the fixed piece 100 together.

[0017] When it is necessary to lift the skirt pile diaphragm, remove the detachable pin 300, rotate the moving piece 200 so that the moving piece 200 and the fixed piece 100 are far apart, and the opening 400 of the lock opens wide. At this time, the opening 400 of the lock can be inserted into the outer edge drum of the skirt pile diaphragm. Then, rotate the moving piece 200 in the opposite direction until the first through hole 120 and the second through hole 210 are aligned. The moving piece 200 and the fixed piece 100 can be combined and locked on both sides of the outer edge drum of the skirt pile diaphragm. At this time, insert the detachable pin 300 to lock the moving piece 200 and the fixed piece 100 together. Finally, the lifting buckle of the crane can be directly connected to the lifting buckle hole 110 of the lock, and the skirt pile diaphragm can be lifted by the crane. Compared to the method of using ropes to bind the skirt pile diaphragm, this locking device has a simple structure, and the crane's hook can be directly connected to the hook hole 110, which can easily and quickly lock or remove the skirt pile diaphragm, avoiding the trouble of collecting and dismantling ropes. At the same time, it can also ensure the locking effect of the skirt pile diaphragm during lifting, so that the lifting work can be carried out safely and reliably. In addition, by using a rigid locking device to act on the outer edge of the skirt pile diaphragm, there is no need to set up a separate lifting structure on the skirt pile diaphragm, which can effectively avoid damage to the skirt pile diaphragm and ensure the integrity and sealing of the skirt pile diaphragm.

[0018] Furthermore, the movable piece 200 and the fixed piece 100 are rotatably connected by a fixed pin 500. When the movable piece 200 rotates around the fixed pin 500, it can make the opening 400 of the lock larger or smaller. Furthermore, the fixed piece 100 has a first recess 130 on its side, and the movable piece 200 has a second recess 220 on its side. When the movable piece 200 rotates close to the fixed piece 100 until the first through hole 120 and the second through hole 210 are aligned, the combined hole formed by the first recess 130 and the second recess 220 is larger than the opening 400. The combined hole of the first recess 130 and the second recess 220 can adapt to the shape of the outer ring of the skirt post diaphragm, thereby further improving the locking effect.

[0019] Furthermore, the lock of this utility model can be divided into two types: horizontal lock and vertical lock. Both horizontal and vertical locks include structures such as a fixed plate 100, a moving plate 200, and a detachable pin 300. The difference lies in: (Refer to...) Figure 1 and Figure 2 For horizontal locking devices, when the moving piece 200 rotates close to the fixed piece 100 until the first through hole 120 and the second through hole 210 are aligned, the hook hole 110, the detachable pin 300, and the opening 400 are arranged in a triangle. At this point, multiple horizontal locking devices can be distributed circumferentially along the skirt pile diaphragm, locking the diaphragm at multiple positions. Multiple hooks on a crane can then be used to achieve horizontal lifting of the skirt pile diaphragm. Because the hook hole 110, the detachable pin 300, and the opening 400 are arranged in a triangle, when the hook is connected to the hook hole 110 and applies force to lift the skirt pile diaphragm, the opening 400 is not in the direction of the force, thus improving the locking effect of the locking device. (Refer to...) Figure 3 and Figure 4 For vertical locking devices, when the moving piece 200 rotates close to the fixed piece 100 until the first through hole 120 and the second through hole 210 are aligned, the hook hole 110, the detachable pin 300, and the opening 400 are arranged in a straight line. At this time, only one vertical locking device can be used to lock the skirt pile isolation, and one hook of the crane can be used to lift the skirt pile diaphragm vertically. The straight-line distribution of the hook hole 110, the detachable pin 300, and the opening 400 ensures that the skirt pile diaphragm, the hook hole 110, the detachable pin 300, and the opening 400 are all distributed in the vertical direction, resulting in a more balanced overall force, making the lifting work more stable and reliable, and the balanced force can further prevent damage to the skirt pile diaphragm.
