Description

Technical Field

[0001] This invention relates to the field of marine engineering equipment technology, and in particular to a pile shoe and pile leg installation structure and installation method. Background Technology

[0002] An offshore platform is a structure that provides production and living facilities for offshore activities such as drilling, oil production, cargo transportation, observation, navigation, and construction. It mainly consists of the platform itself and its supporting structure. The supporting structure of an offshore platform mainly includes legs and pile shoes. The pile shoes are fixed to the bottom of the legs and inserted into the seabed sediment to bear the pressure of the entire offshore platform. Currently, the pile shoes and legs can be detached and installed through an installation structure.

[0003] For example, Chinese Patent Publication No. CN213625568U discloses a detachable pile shoe, which includes: a cylinder, pins, and a top plate. The cylinder has evenly distributed connecting plates on its circumference, and each connecting plate is provided with a pin. The cylinder also has evenly distributed top plates on its circumference. The top plates are connected to the cylinder by evenly distributed partition assemblies and inclined structure assemblies. By inserting the four pins into the circular holes, the pile shoe is connected and fixed to the pile leg. Conversely, the pile shoe can be disassembled by simply pulling out the pins.

[0004] For example, Chinese Patent Publication No. CN112796292A discloses a high-strength column leg pile shoe for an offshore substation, including a pile shoe and a column leg. Telescopic rods are slidably installed inside the two sleeves. Connecting rods are rotatably installed at opposite ends of the two telescopic rods. Locking blocks are fixedly installed at the top ends of the two connecting rods, and pressure blocks are fixedly installed at the bottom ends of the two connecting rods. Slots are provided at the left and right ends of the column leg. In this high-strength column leg pile shoe for an offshore substation, the column leg presses down on the pressure blocks. During the pressing process, the pressure blocks, through the connecting rods, sleeves, and telescopic rods, drive the two locking blocks into the slots.

[0005] However, the applicant found that although the detachable pile shoe disclosed in the first prior art fixes the pile shoe and pile leg by inserting a pin into a round hole and removing the pin allows for disassembly, the fixation method is relatively simple and not strong or stable enough. The high-strength column leg pile shoe of the offshore substation disclosed in the second prior art fixes the pile shoe by inserting a clip into a slot, but the fixation method is relatively simple and it is not convenient to disassemble the pile shoe and pile leg after fixation. Summary of the Invention

[0006] In view of this, the purpose of this invention is to propose a pile shoe and pile leg installation structure and installation method to solve the problem that in the process of detachable installation of pile shoes and pile legs, existing installation structures mostly use only one fixing method to fix the pile shoes and pile legs. The fixing method is relatively simple, and the installation and fixing effect is not strong and stable enough, which leads to the problem that the installation points of pile shoes and pile legs are prone to shaking and breakage.

[0007] To achieve the above objectives, the present invention provides a pile shoe and pile leg installation structure, including a pile shoe body and a pile leg, wherein a support column extends upward from the middle of the pile shoe body, a connecting column is fixedly connected to the top of the support column, and a connecting groove for the connecting column to be inserted is provided at the bottom of the pile leg. The pile leg is provided with a plurality of protrusions with threaded holes along its length direction, and the support column is fixedly connected with a plurality of positioning blocks with threaded holes along its length direction. A connecting plate is placed on the surface of the protrusions and positioning blocks. The connecting plate is provided with a plurality of placement slots for placing the protrusions and positioning blocks. The connecting plate is provided with locking bolts that are threadedly connected to the threaded holes on the protrusions and positioning blocks. The connecting plate is fixedly connected to an auxiliary support leg for supporting the pile shoe body, and the position of the connecting plate on the protrusion and positioning block can be changed to adjust the position of the auxiliary support leg. The support column is provided with a receiving groove for placing the protrusion, and an elastic locking part is provided in the receiving groove. When the connecting plate is installed, it will push the protrusion to move the elastic locking part, so that the elastic locking part extends into the connecting groove to lock and fix the connecting column.

[0008] Preferably, each side of the leg is provided with multiple protrusions, and the multiple protrusions are equally spaced on the leg. Each side of the support column is fixedly connected with multiple positioning blocks, and the multiple positioning blocks are equally spaced on the support column.

[0009] Preferably, the auxiliary support leg includes a sleeve, which is fixedly connected to the connecting plate. A sliding rod is slidably inserted into the sleeve, and an insertion rod is fixedly connected to the end of the sliding rod.

[0010] Preferably, a bolt is fixedly connected to the slide rod, a through groove is provided on the sleeve for the bolt to move, and a nut is threaded onto the bolt.

[0011] Preferably, the receiving groove includes a movable groove one and a movable groove two formed on the pile leg, the protrusion is slidably connected in the movable groove one, and the movable groove one passes through the pile leg and communicates with the outside, the movable groove two communicates with the connecting groove, and a channel is formed between the movable groove one and the movable groove two.

[0012] Preferably, the elastic locking part includes a connecting rod slidably disposed in the channel, one end of the connecting rod is connected to a protrusion, the other end of the connecting rod is fixedly connected to a locking block, the connecting rod is provided with a locking groove adapted to the locking block, and an elastic element is sleeved on the connecting rod.

[0013] Preferably, the elastic element is a spring, which is sleeved on the connecting rod, and the two ends of the spring abut against the protrusion and the moving groove, respectively.

[0014] An installation method for a pile shoe and pile leg mounting structure includes the following steps: Step 1: Insert the connecting post into the connecting groove and adjust the depth of the connecting post into the connecting groove to fine-tune the overall length of the pile shoe body and the pile leg. Step two: Then, the connecting plate is placed on the protrusion and positioning block. The protrusion and positioning block are inserted into the placement groove on the connecting plate. Then, the locking bolt is tightened. The locking bolt on the connecting plate is screwed into the protrusion and positioning block and threadedly connected to the threaded hole, which initially fixes the pile shoe body and the pile leg. Step 3: During the process of pressing the connecting plate to make the protrusion engage with the placement groove, the spring force will be overcome to push the protrusion to move. The protrusion will then push the connecting rod and the locking block to move, so that the locking block is inserted into the locking groove, which will fix the pile shoe body and the pile leg again, making the installation of the pile shoe body and the pile leg more secure. Step four: In step two, the positions of the four auxiliary legs can be adjusted according to the geological conditions of the seabed at the pile insertion location. This allows the auxiliary legs to be inserted into the seabed according to the geological conditions, providing auxiliary support for the pile shoe body. Specifically, the position of the connecting plate on the pile shoe body and the pile leg is changed, and the connecting plate is fixed by locking bolts. The change in the position of the connecting plate will not affect the installation and fixing effect between the pile shoe body and the pile leg.

[0015] Step 5: Loosen the nut to change the position of the sliding rod in the sleeve. After the sliding rod moves, tighten the nut. This changes the distance between the insert rod and the pile shoe body, changes the support range of the auxiliary leg on the pile shoe body, and improves the support effect on the pile shoe body.

[0016] The beneficial effects of this invention are as follows: The pile shoe and pile leg installation structure and method provided by this invention, by fitting a connecting plate onto a protrusion and a positioning block, with the protrusion and positioning block engaging in the placement groove, and tightening the locking bolt to fix the connecting plate onto the protrusion and positioning block, provides initial fixation for the pile shoe body and pile leg. During the process of pushing the connecting plate to move the protrusion and positioning block into the placement groove, the protrusion is also pushed to move the elastic locking part, causing the elastic locking part to extend out of the connecting groove and lock the connecting column, thus further fixing the pile shoe body and pile leg. Through these two fixing methods, the installation of the pile shoe body and pile leg is made more secure. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, a pile shoe and pile leg installation structure includes a pile shoe body 1 and a pile leg 2. A support column 3 extends upward from the middle of the pile shoe body 1. A connecting column 4 is fixedly connected to the top of the support column 3. A connecting groove 5 for the connecting column 4 to be inserted is provided at the bottom of the pile leg 2. The pile leg 2 is provided with a plurality of protrusions 6 with threaded holes along its length direction, and the support column 3 is fixedly connected with a plurality of positioning blocks 7 with threaded holes along its length direction. A connecting plate 8 is placed on the surface of the protrusions 6 and the positioning blocks 7. A plurality of placement slots 9 for placing the protrusions 6 and the positioning blocks 7 are provided on the connecting plate 8. Locking bolts 10 are provided on the connecting plate 8 and are threadedly connected to the threaded holes on the protrusions 6 and the positioning blocks 7. A screw hole is provided on the connecting plate 8, and the locking bolts 10 are threadedly connected to the screw hole on the connecting plate 8. An auxiliary support leg 11 for supporting the pile shoe body 1 is fixedly connected to the connecting plate 8, and the position of the connecting plate 8 on the protrusion 6 and the positioning block 7 can be changed to adjust the position of the auxiliary support leg 11. The support column 3 is provided with a receiving groove 12 for placing the protrusion 6. An elastic locking part 13 is provided in the receiving groove 12. When the connecting plate 8 is installed, the protrusion 6 will be pushed to move the elastic locking part 13, so that the elastic locking part 13 extends into the connecting groove 5 to lock and fix the connecting column 4.

[0023] By fitting the connecting plate 8 onto the protrusion 6 and the positioning block 7, and inserting the protrusion 6 and the positioning block 7 into the placement groove 9, and tightening the locking bolt 10 to fix the connecting plate 8 onto the protrusion 6 and the positioning block 7, the pile shoe body 1 and the pile leg 2 are initially fixed. As the connecting plate 8 is moved, causing the protrusion 6 and the positioning block 7 to be inserted into the placement groove 9, the protrusion 6 is also pushed to move the elastic locking part 13, causing the elastic locking part 13 to extend out of the connecting groove 5 to lock and fix the connecting column 4, thus further fixing the pile shoe body 1 and the pile leg 2. Through the above two fixing methods, the installation between the pile shoe body 1 and the pile leg 2 is more secure.

[0024] The position of the connecting plate 8 on the pile shoe body 1 and the pile leg 2 is changed, and the connecting plate 8 is fixed by the locking bolt 10. The change in the position of the connecting plate 8 will not affect the installation and fixing effect between the pile shoe body 1 and the pile leg 2, so that the auxiliary support leg 11 can be inserted into the seabed according to the geological conditions to provide auxiliary support for the pile shoe body 1.

[0025] like Figure 2 As shown, in a preferred embodiment of the present invention, a plurality of protrusions 6 are provided on each side of the pile leg 2, and the plurality of protrusions 6 are equally spaced on the pile leg 2. A plurality of positioning blocks 7 are fixedly connected to each side of the support column 3, and the plurality of positioning blocks 7 are equally spaced on the support column 3. By providing protrusions 6 on each side of the pile leg 2 and positioning blocks 7 on each side of the support column 3, the stability of the connection between the pile shoe body 1 and the pile leg 2 is improved with the cooperation of the connecting plate 8, making the pile shoe body 1 more firmly and stably support the pile leg 2 and the offshore platform. The distance between two adjacent protrusions 6, the distance between two adjacent positioning blocks 7, and the distance between adjacent protrusions 6 and positioning blocks 7 after the pile shoe body 1 and the pile leg 2 are all equal. By setting the distances equally, it is convenient to change the position of the connecting plate 8 on the protrusions 6 and positioning blocks 7.

[0026] like Figure 9 As shown, in another preferred embodiment of the present invention, the auxiliary support leg 11 includes a sleeve 111, which is fixedly connected to the connecting plate 8. A sliding rod 112 is slidably inserted into the sleeve 111, and an insert rod 113 is fixedly connected to the end of the sliding rod 112. A bolt 114 is fixedly connected to the sliding rod 112. A through groove for the bolt 114 to move is provided on the sleeve 111, and a nut 115 is threaded onto the bolt 114.

[0027] When it is necessary to change the distance between the insert rod and the pile shoe body, first loosen the nut to release the bolt, then move the slide rod. As the slide rod moves inside the sleeve, it will also drive the insert rod to move. After moving to the appropriate position, tighten the nut to fix the bolt, slide rod and insert rod. This changes the distance between the insert rod 113 and the pile shoe body 1, changes the support range of the auxiliary support leg 11 on the pile shoe body 1, and improves the support effect on the pile shoe body 1.

[0028] like Figure 3 As shown, in another preferred embodiment of the present invention, the receiving groove 12 includes a movable groove 1 and a movable groove 2 formed on the pile leg 2. The protrusion 6 is slidably connected in the movable groove 1, and the movable groove 1 passes through the pile leg 2 and communicates with the outside. The movable groove 2 communicates with the connecting groove 5, and a channel is formed between the movable groove 1 and the movable groove 2. The elastic locking part 13 includes a connecting rod 131 slidably disposed in the channel. One end of the connecting rod 131 is connected to the protrusion 6, and the other end of the connecting rod 131 is fixedly connected to a locking block 132. A locking groove adapted to the locking block 132 is formed on the connecting column 4, and an elastic element is sleeved on the connecting rod 131. The elastic element is a spring 133. The spring 133 is sleeved on the connecting rod 131, and the two ends of the spring 133 abut against the protrusion 6 and the movable groove 1, respectively.

[0029] The connecting plate 8 is fitted onto the protrusion 6 and the positioning block 7. The protrusion 6 and the positioning block 7 are inserted into the placement groove 9 on the connecting plate 8. Then, the locking bolt 10 is tightened. The locking bolt 10 on the connecting plate 8 is screwed into the protrusion 6 and the positioning block 7 and threadedly connected to the threaded hole, which initially fixes the pile shoe body 1 and the pile leg 2. When the connecting plate 8 is pressed to make the protrusion 6 engage with the placement groove 9, the elastic force of the spring 133 will be overcome to push the protrusion 6 to move. The protrusion 6 will then push the connecting rod 131 and the locking block 132 to move, so that the locking block 132 is inserted into the locking groove, which again fixes the pile shoe body 1 and the pile leg 2, making the installation of the pile shoe body 1 and the pile leg 2 more secure.

[0030] like Figure 4 and Figure 5 As shown, when it is necessary to adjust the position of the insertion rod according to the geological conditions of the seabed at the insertion location, the position of the connecting plate on the protrusion and positioning block is changed, and then the connecting plate is fixed on the protrusion and positioning block by locking bolts. The position of the four auxiliary legs 11 can be adjusted accordingly, so that the auxiliary legs 11 can be inserted into the seabed according to the geological conditions to provide auxiliary support for the pile shoe body 1. That is, the position of the connecting plate 8 on the pile shoe body 1 and the pile leg 2 is changed, and the connecting plate 8 is fixed by locking bolts 10. The change of the position of the connecting plate 8 will not affect the installation and fixing effect between the pile shoe body 1 and the pile leg 2.

[0031] like Figure 6 and Figure 7As shown, by adjusting the depth of the connecting column 4 inserted into the connecting groove 5, the connecting plate 8 can fix the pile shoe body 1 and the pile leg 2, and can finely adjust the overall length of the pile shoe body 1 and the pile leg 2 to adapt to different seabed depths.

[0032] An installation method for a pile shoe and pile leg mounting structure includes the following steps: Step 1: Insert the connecting post 4 into the connecting groove 5. Adjusting the depth of the connecting post 4 into the connecting groove 5 can fine-tune the overall length of the pile shoe body 1 and the pile leg 2. Step 2: Then, the connecting plate 8 is fitted onto the protrusion 6 and the positioning block 7. The protrusion 6 and the positioning block 7 are inserted into the placement groove 9 on the connecting plate 8. Then, the locking bolt 10 is tightened. The locking bolt 10 on the connecting plate 8 is screwed into the protrusion 6 and the positioning block 7 and threadedly connected to the threaded hole, which initially fixes the pile shoe body 1 and the pile leg 2. Step 3: During the process of pressing the connecting plate 8 to make the protrusion 6 engage with the placement groove 9, the elastic force of the spring 133 will be overcome to push the protrusion 6 to move. The protrusion 6 will then push the connecting rod 131 and the locking block 132 to move, so that the locking block 132 is inserted into the locking groove, which will fix the pile shoe body 1 and the pile leg 2 again, making the installation of the pile shoe body 1 and the pile leg 2 more secure. Step four: In step two, the positions of the four auxiliary legs 11 can be adjusted according to the geological conditions of the seabed at the pile insertion location, so that the auxiliary legs 11 can be inserted into the seabed according to the geological conditions to provide auxiliary support for the pile shoe body 1. That is, the position of the connecting plate 8 on the pile shoe body 1 and the pile leg 2 is changed, and the connecting plate 8 is fixed by the locking bolt 10. The change in the position of the connecting plate 8 will not affect the installation and fixing effect between the pile shoe body 1 and the pile leg 2.

[0033] Step 5: Loosen nut 115, change the position of slide rod 112 on sleeve 111, and tighten nut 115 after slide rod 112 moves. This changes the distance between insert rod 113 and pile shoe body 1, changes the support range of auxiliary support leg 11 on pile shoe body 1, and improves the support effect on pile shoe body 1.
