Description

Technical Field

[0001] The invention relates to the technical field of pile shoe installation, in particular to an installation device for setting pile shoes of a high-pile dock. Background Art

[0002] A high-pile wharf is composed of the superstructure (pile platform or cap), pile foundation, shore connection structure, shore lock and wharf equipment. The superstructure constitutes the wharf surface and is connected to the pile foundation as a whole. It directly bears the vertical and horizontal loads acting on the wharf surface and transfers them to the pile foundation. The pile foundation is used to support the superstructure and transfer the load of the superstructure and wharf surface to the deep foundation. It is also conducive to stabilizing the shore slope. The main function of the shore connection structure is to connect the pile platform with the land area of ​​the port area.

[0003] The function of pile foundation is to support the superstructure and transfer the load to the deep ground, which is also conducive to stabilizing the bank slope. This type of structure is suitable for a variety of foundation conditions, especially on soft soil foundation. High-pile docks are widely used because of their air-permeable structure characteristics, small impact on water flow and small wave radiation. In actual construction, the design and construction of pile foundation is one of the key links, including the design of pile shoes and the process of inserting them into the seabed soil. This step is crucial to ensure the stability and durability of the dock.

[0004] When the jack-up platform is operating, the pile shoes need to be inserted into the seabed soil to support the platform to operate away from the sea surface; after the operation is completed, the platform needs to pull up the pile legs and pile shoes and retract them into the hull. When the platform pulls out piles, it needs to overcome the gravity of the soil on the top of the pile shoes, the friction between the side walls of the pile shoes and the soil, the deadweight of the pile legs and pile shoes, and the adsorption force at the bottom of the pile shoes. Therefore, during the pile pulling process, the pile shoes and the seabed soil always remain in a bonded state, which creates huge resistance to pile pulling and increases the difficulty of pile pulling. Summary of the invention

[0005] The purpose of the present invention is to provide an installation device for setting pile shoes of high-pile docks to solve the problem proposed in the above background technology that during the pile pulling process, the pile shoes and the seabed soil always remain in a bonding state, causing huge resistance to pile pulling and increasing the difficulty of pile pulling.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an installation device for setting pile shoes of a high-pile dock, comprising a fixed pile shoe, and further comprising:

[0007] A first movable shoe, the first movable shoe is rotatably connected to the surface of the fixed pile shoe and is locked with the fixed pile shoe through a locking assembly;

[0008] An annular groove, wherein the bottom surface of the annular groove is provided with a plurality of spiral through grooves penetrating the first movable shoe, and a sealing ring is rotatably connected in the top opening of the annular groove, and the top of the sealing ring is fixedly connected with an external connecting joint;

[0009] A plurality of connecting grooves, the connecting grooves comprising a first groove and a second groove;

[0010] A plurality of second movable shoes, each of the surfaces of which is fixedly connected with a connecting slider, and a limiting component is provided at the bottom of the connecting slider for limiting the state of the connecting slider in the first groove;

[0011] When the pile shoe is inserted into the pile, the connecting slider is arranged in the first groove to limit the relative movement between the second movable shoe and the first movable shoe; when the pile needs to be pulled out, the connecting slider cancels the locking of the locking assembly and the limiting of the limiting assembly, and the connecting slider is arranged in the second groove to provide freedom for the relative movement between the second movable shoe and the first movable shoe, and pump water into the external joint.

[0012] It should be understood that the working state of the pile shoe is defined as the state of the pile shoe when the offshore platform pile is inserted. In the working state, the pile shoe is usually installed at the bottom of the pile leg, and the bottom surface of the pile shoe is in contact with the seabed soil and is stable at a depth inside the seabed. Accordingly, when pulling the pile, the pile shoe is pulled above the seabed surface by the pile pulling system.

[0013] During insertion, the connecting slider is arranged in the first groove, so that the relative movement between the second movable shoe and the first movable shoe is restricted, and under the locking of the locking assembly, the relative movement of the first movable shoe relative to the first fixed pile shoe is restricted, thereby forming a stable pile shoe as a whole, ready for insertion;

[0014] Before pulling out the pile, first cancel the locking of the first movable shoe and the fixed pile shoe by the locking component and the limiting of the connecting slider by the limiting component, and connect the pipeline of the external pumping machine to the external connection joint to pump air. The gas will enter the annular groove and pass through the spiral groove to flush the bottom end of the fixed pile shoe, thereby increasing the pressure between the bottom surface of the pile shoe and the seabed soil and reducing the adsorption force. At the same time, under the action of the spiral groove, the first movable shoe will generate a rotational tendency force, which is conducive to the movement between the first movable shoe and the seabed soil and the separation of the first movable shoe from the seabed soil.

[0015] When the first movable boot and the fixed pile boot move upward under the drive of the pile leg (26), the first movable boot will generate longitudinal sliding with the second movable boot, generating relative movement, thereby preventing the second movable boot from exerting force on the detachment of the first movable boot, and during the rotation of the first movable boot, the second groove will provide a clearance space for the connecting slider, so that the second movable boot and the first movable boot can have relative rotation freedom, thereby avoiding obstruction to the initial rotation of the first movable boot. When the first movable boot continues to rotate after rotating and detaching from the seabed soil, the connecting slider will act on the wall of the second groove, thereby driving the second movable boot to rotate, thereby driving the second movable boot to move, generating relative movement with the seabed soil surface, and facilitating further detachment of the second movable boot from the seabed soil. The entire detachment process, the multi-layer detachment formed, and the combined effect of rotation and flushing during the detachment process are conducive to further enhancing the pile pulling ability.

[0016] Specifically, a fixed card plate is fixedly connected between the side walls at the top of the inner wall of the first groove, and a U-shaped plug-in card slot adapted to the fixed card plate is provided on the surface of the connecting slider.

[0017] It should be understood that by providing a sliding connection between the fixed card plate and the plug-in card slot, the connecting slider is limited in the first slot, thereby limiting the second movable shoe from being separated from the first movable shoe.

[0018] Specifically, a first installation slot is provided on the bottom surface of the second slot, a movable card plate is slidably provided inside the first installation slot, the movable card plate and the plug-in card slot are adapted to each other, and a first supporting spring is fixedly connected between the movable card plate and the bottom surface of the first installation slot.

[0019] It should be understood that by providing the movable clamping plate, the connecting slider moved into the second slot is limited, so as to prevent the connecting slider from being separated from the second slot, thereby limiting the second movable shoe from being separated from the second movable shoe;

[0020] During installation, press the movable card plate to cancel the limit. After the connecting slider is inserted into the second slot, cancel the pressing. Under the support of the first supporting spring, the movable card plate rises and is inserted into the plug-in slot to form a connection limit, but it does not limit the movement of the connecting slider in the second slot.

[0021] As an optional technical solution of the present invention, the limit assembly includes

[0022] a second mounting groove, the second mounting groove being arranged on a side wall of the connecting groove;

[0023] A limit plate, which is slidably inserted into the second mounting groove and has a guiding inclined surface at its end, and the top surface of the limit plate contacts and limits the bottom of the connecting slider;

[0024] A second supporting spring, wherein the second supporting spring is located in the second mounting groove and supports the limiting state of the limiting plate.

[0025] It should be understood that when the connecting slider is moved from the second groove to the first groove, the limit plate will be pushed first until the limit plate is retracted into the second mounting groove, and then the second movable boot will be pushed upward until the bottom surface of the connecting slider is above the limit plate. Under the action of the second support spring, the limit plate will move to the bottom surface of the connecting slider, and limit the connecting slider in the first groove, thereby limiting the relative movement between the second movable boot and the first movable boot.

[0026] As a technical solution further optimized by the present invention, a pressing rod is fixedly connected to the top of the movable card plate, and the pressing rod passes through the first movable shoe and extends to the outside of the first movable shoe, so that the height of the movable card plate can be adjusted by pressing the pressing rod.

[0027] It should be understood that during the installation process, since the second movable boot is very close to the first movable boot, it is difficult to operate the movable clamping plate. By extending the pressing rod out of the second movable boot, it is convenient for the staff to press and adjust from above the second movable boot.

[0028] As a technical solution further optimized by the present invention, the surface of the limit plate has an inclined guide groove, the top end of the inclined guide groove is connected to a give-way groove opened on the surface of the limit plate, the top end of the inclined guide groove is slidably provided with a guide pin, and the guide pin is fixedly connected to the top of the movable clamping plate.

[0029] It should be understood that in the process of pressing the movable card plate, the movable card plate will synchronously drive the guide pin to move in the inclined guide groove, and will push the limit plate into the second mounting groove, so as to facilitate the connection slider bracket to be inserted into the first groove and slidingly connected with the fixed card plate. After the connection is completed, after the pressure on the movable card plate is cancelled, the limit plate will be reset under the support of the second support spring, and the connection slider will be limited, so as to realize the quick connection between the first movable boot and the second movable boot.

[0030] As a technical solution further optimized by the present invention, a linkage ring is rotatably arranged inside the annular groove, a plurality of wedge blocks distributed in an annular array are fixedly connected to the bottom surface of the linkage ring, a plurality of through holes facing the inclined surfaces of the wedge blocks are provided on the top of the linkage ring, a first adjustment groove is provided between the annular groove and the plurality of second mounting grooves, a linkage frame is slidably arranged in the first adjustment groove, and the two ends of the linkage frame are respectively fixedly connected to the linkage ring and the limit plate.

[0031] It should be understood that when flushing, water will pass through the through hole and impact the inclined surface of the wedge block, pushing the wedge block, thereby driving the linkage ring to rotate. The linkage ring will synchronously drive the limit plate to move through the linkage frame, cancel the limit on the connecting slider, and realize that while flushing the bottom surface of the first movable boot, the limit between the first movable boot and the second movable boot is automatically released, and a certain degree of freedom is provided for the relative movement of the first movable boot and the second movable boot.

[0032] Specifically, the top of the fixed pile shoe is threadedly connected with a pile leg.

[0033] As an optional technical solution of the present invention, the locking assembly includes:

[0034] A connecting ring, the connecting ring being slidably sleeved on the surface of the pile leg and having a height adjustment component connected to the pile leg (26);

[0035] Four locking frames, the four locking frames are fixedly connected to the surface of the connecting ring and have plug-in holes at their ends;

[0036] Four positioning pins are fixedly connected to the top surface of the first movable shoe and inserted into the insertion holes at corresponding positions.

[0037] It should be understood that after the pile leg is threadedly connected to the fixed pile shoe, the height of the connecting ring is lowered by the height adjustment assembly, thereby synchronously driving the locking frame to adjust its height until the plug hole and the positioning pin are connected to achieve locking;

[0038] When the lock needs to be canceled, the connecting ring is lifted by the height adjustment component, and the plug-in hole of the locking frame is simultaneously driven to disengage, thereby canceling the lock.

[0039] Specifically, the top surface of the fixed pile shoe is fixedly connected with four U-shaped limit frames, and the limit frames are limitedly inserted on the surface of the locking frame at the corresponding position to limit the relative movement between the pile leg and the fixed pile shoe, thereby maintaining the stability of the threaded connection;

[0040] It needs to be further explained that, in the process of adjusting the connection ring to rise and contact and lock, when the plug-in hole is separated from the positioning pin, the limit frame is still plugged into the locking frame and is in a limited state to maintain the stability of the pile pulling.

[0041] As an optional technical solution of the present invention, the height adjustment component includes:

[0042] Two second adjustment grooves, the two second adjustment grooves are arranged on the inner wall of the connecting ring;

[0043] Two electric cylinders are respectively fixedly mounted on the inner bottom surfaces of the two second adjustment grooves, and are fixedly connected with connecting blocks on the tops. The connecting sliders are fixedly connected to the surfaces of the pile legs, and the connecting blocks are slidably arranged in the second adjustment grooves to seal the second adjustment grooves.

[0044] It should be understood that when the height of the connecting ring needs to be adjusted, the two electric cylinders are started at the same time, and the two electric cylinders are pushed at the same time to lower the height of the connecting ring, and at the same time, they shrink, which will drive the connecting ring to increase its height.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] 1. During the pile pulling process, the second movable boot and the first movable boot can have relative rotational freedom to avoid obstruction to the initial rotation of the first movable boot. When the first movable boot continues to rotate after rotating away from the seabed soil, the connecting slider will act on the second groove wall, which will drive the second movable boot to rotate, and then drive the second movable boot to move, and produce relative movement with the surface of the seabed soil, which is conducive to further promoting the separation of the second movable boot from the seabed soil. The whole separation process, the multi-layer separation formed and the comprehensive effect of rotational movement and flushing during the separation process are conducive to further enhancing the pile pulling ability.

[0047] 2. When flushing, water will pass through the through hole and impact the inclined surface of the wedge block, pushing the wedge block, thereby driving the linkage ring to rotate. The linkage ring will synchronously drive the limit plate to move through the linkage frame, canceling the limit on the connecting slider, and realizing that while flushing the bottom surface of the first movable boot, the limit between the first movable boot and the second movable boot is automatically released, and a certain degree of freedom is provided for the relative movement of the first movable boot and the second movable boot.

[0048] 3. When flushing, water will pass through the through hole and impact the inclined surface of the wedge block, pushing the wedge block, thereby driving the linkage ring to rotate. The linkage ring will synchronously drive the limit plate to move through the linkage frame, canceling the limit on the connecting slider, and realizing that while flushing the bottom surface of the first movable boot, the limit between the first movable boot and the second movable boot is automatically released, and a certain degree of freedom is provided for the relative movement of the first movable boot and the second movable boot.

DETAILED DESCRIPTION

[0061] See also Figure 1-Figure 10 The present invention provides a technical solution: a mounting device for setting pile shoes of a high-pile dock, comprising a fixed pile shoe 1, and also comprising:

[0062] A first movable shoe 2, the first movable shoe 2 is rotatably connected to the surface of the fixed pile shoe 1, and is locked with the fixed pile shoe 1 through a locking assembly;

[0063] The annular groove 3 has a plurality of spiral grooves 201 penetrating the first movable shoe 2 on its bottom surface, and a sealing ring 4 is rotatably connected in the top opening of the annular groove 3, and an external connecting joint 5 is fixedly connected to the top of the sealing ring 4;

[0064] A plurality of connecting grooves 6, the connecting grooves 6 comprising a first groove 601 and a second groove 602;

[0065] A plurality of second movable shoes 7, surfaces of the plurality of second movable shoes 7 are fixedly connected with connecting slide blocks 8, and a limiting component is provided at the bottom of the connecting slide block 8 for limiting the state of the connecting slide block 8 in the first groove 601;

[0066] When the pile shoe is inserted into the pile, the connecting slider 8 is arranged in the first groove 601 to limit the relative movement between the second movable shoe 7 and the first movable shoe 2; when the pile needs to be pulled out, the connecting slider 8 cancels the locking of the locking component and the limiting of the limiting component, and the connecting slider 8 is arranged in the second groove 602 to provide freedom for the relative movement between the second movable shoe 7 and the first movable shoe 2, and pumps water into the external joint 5.

[0067] It should be understood that the working state of the pile shoe is defined as the state of the pile shoe when the offshore platform pile is inserted. In the working state, the pile shoe is usually installed at the bottom of the pile leg 26, and the bottom surface of the pile shoe is in contact with the seabed soil and is stable at a depth inside the seabed. Accordingly, when pulling the pile, the pile shoe is pulled above the seabed surface by the pile pulling system.

[0068] During insertion, the connecting slider 8 is arranged in the first groove 601, so that the relative movement between the second movable shoe 7 and the first movable shoe 2 is restricted, and under the locking of the locking assembly, the relative movement of the first movable shoe 2 relative to the first fixed pile shoe 1 is restricted, thereby forming a stable pile shoe as a whole, ready for insertion;

[0069] Before pulling out the pile, first cancel the locking of the first movable shoe 2 and the fixed pile shoe 1 by the locking component and the limiting of the connecting slider 8 by the limiting component, connect the pipeline of the external pumping machine to the external connection joint 5, and pump air. The gas will enter the annular groove 3 and pass through the spiral groove 201 to flush the bottom end of the fixed pile shoe 1, thereby increasing the pressure between the bottom surface of the pile shoe 100 and the seabed soil and reducing the adsorption force. At the same time, under the action of the spiral groove 201, the first movable shoe 2 will generate a rotational tendency force, which is conducive to the movement between the first movable shoe 2 and the seabed soil and the separation of the first movable shoe 2 from the seabed soil.

[0070] When the first movable boot 2 and the fixed pile boot 1 move upward driven by the pile leg 26, the first movable boot 2 will generate longitudinal sliding with the second movable boot 7, generating relative movement, thereby preventing the second movable boot 7 from exerting force on the detachment of the first movable boot 2, and during the rotation of the first movable boot 2, the second groove 602 will provide a clearance space for the connecting slider 8, so that there can be relative rotation freedom between the second movable boot 7 and the first movable boot 2, thereby avoiding obstruction to the initial rotation of the first movable boot 2. When the first movable boot 2 continues to rotate after rotating away from the seabed soil, the connecting slider 8 will act on the wall of the second groove 602, thereby driving the second movable boot 7 to rotate, thereby driving the second movable boot 7 to move, generating relative movement with the surface of the seabed soil, and helping to further promote the detachment of the second movable boot 7 from the seabed soil. The entire detachment process, the multi-layer detachment formed, and the combined effect of rotational movement and flushing during the detachment process are conducive to further enhancing the pile pulling ability.

[0071] Specifically, a fixed card plate 9 is fixedly connected between the side walls at the top of the inner wall of the first groove 601 , and a U-shaped plug-in card slot 10 adapted to the fixed card plate 9 is opened on the surface of the connecting slider 8 .

[0074] It should be understood that by providing the movable clamping plate 12, the connecting slider 8 moved into the second groove 602 is limited, so as to prevent the connecting slider 8 from being separated from the second groove 602, thereby limiting the second movable shoe 7 from being separated from the second movable shoe 7;

[0075] During installation, press the movable card plate 12 to cancel the limit. After the connecting slider 8 is inserted into the second slot 602, cancel the pressing. Under the support of the first support spring 13, the movable card plate 12 rises and is inserted into the plug-in slot 10, forming a connection limit, but it does not limit the movement of the connecting slider 8 in the second slot 602.

Under the action of the second support spring 16, the limit plate 15 will move to the bottom surface of the connecting slider 8, and limit the connecting slider 8 in the first groove 601, thereby limiting the relative movement between the second movable shoe 7 and the first movable shoe 2.

After the connection is completed, after the pressure on the movable card plate 12 is cancelled, the limit plate 15 will be reset under the support of the second support spring 16, and the connection slider 8 will be limited, so as to realize the quick connection between the first movable boot 2 and the second movable boot 7.

The linkage ring 21 will synchronously drive the limit plate 15 to move through the linkage frame 25, cancel the limit on the connecting slider 8, and realize that while flushing the bottom surface of the first movable boot 2, the limit between the first movable boot 2 and the second movable boot 7 is automatically released, and a certain degree of freedom is provided for the relative movement of the first movable boot 2 and the second movable boot 7.
