Description

Technical Field

[0001] This utility model relates to a platform base for an underwater pile stabilizing frame for pile driving, belonging to the technical field of offshore wind power pile foundation construction and installation. Background Technology

[0002] Floating offshore wind power construction sites are usually located in deep-sea areas far from the coast. During the pile driving operation of offshore wind power piles, they may be affected by the currents in the deep sea and become deviated. Since the pile driving construction and installation must be kept vertical, it is necessary to correct the deviated piles to a vertical and stable state.

[0003] To provide thrust correction for the tilted pile foundation cylinder, the existing technology (Chinese Patent Publication No. CN114319356B) uses a hydraulic jack that provides thrust, which is installed on a guide frame to obtain the installation foundation. However, the installation foundation cannot be adjusted in position with the hydraulic jack. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a platform base for an underwater pile stabilizing frame for pile driving.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a platform base for an underwater pile stabilizing frame for pile driving, comprising: Platform board; The platform plate is provided with a weight-reducing structural hole. The platform plate at the structural hole has a rectangular clamping beam. A cylinder base is clamped in the rectangular clamping beam. The cylinder base has a rectangular slot that is interference-fitted with the rectangular clamping beam and clamped tightly. The cylinder base is in contact with the side plane of the platform plate at the rectangular clamping beam.

[0007] The platform plate has a first pile hole in the middle for the pile foundation cylinder to pass through during pile driving.

[0008] A second double-eared plate inclined toward the first pile hole is fixed on the cylinder base, and an adjusting cylinder A is rotatably mounted on the second double-eared plate via a hinge shaft.

[0009] The platform plate has a fourth double-ear eye plate fixed on its left and right sides and bottom surface. The fourth double-ear eye plate can be rotated back and forth and hinged to a seventh double-ear eye plate.

[0010] The platform plate is fixed with a fifth double-ear eye plate on the bottom surface of the front and rear sides. The fifth double-ear eye plate is hinged to an adjusting cylinder B that can rotate back and forth. The adjusting cylinder B is mounted with a sixth double-ear eye plate that can rotate back and forth.

[0011] The platform board is equipped with a level sensor.

[0012] A third double-ear eye plate is fixed on the platform plate, and a semi-circular guide cylinder is hinged to the third double-ear eye plate that can rotate left and right.

[0013] A guide cylinder linkage device is fixedly installed on the outer wall of the semi-circular guide cylinder.

[0014] The beneficial effects of this utility model are as follows: When it is necessary to adjust the position of the hydraulic cylinder base on the rectangular clamping beam, an upward pushing force is provided to the vertical bottom surface of the hydraulic cylinder base. The rectangular slot of the hydraulic cylinder base disengages from the rectangular clamping beam for position adjustment. After the adjustment is in place, the rectangular slot of the hydraulic cylinder base is then pressurized to fit the rectangular clamping beam. At this time, the hydraulic cylinder base is restored to contact with the side plane of the platform plate at the rectangular clamping beam, so that the hydraulic cylinder base can be used as the installation base for adjusting hydraulic cylinder A on the rectangular clamping beam for position adjustment. This solves the problem that the existing technology cannot adjust the position of the installation base of the hydraulic jack. Attached Figure Description

[0016] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0017] like Figures 1 to 7 As shown.

[0018] This application discloses an underwater pile stabilization frame for pile driving, comprising: An anti-sinking platform 41 is provided to provide a working space environment. A platform base 3 that can rotate back and forth is installed on the anti-sinking platform 41. A guide cylinder 1 that can rotate left and right is installed on the platform base 3. The guide cylinder 1 is composed of two semi-circular guide cylinders 11. The semi-circular guide cylinders 11 can be rotated left and right on the platform base 3. The two semi-circular guide cylinders 11 are driven by the guide cylinder linkage device 2 to rotate left and right on the platform base 3 to make multi-point contact and hold the pile foundation cylinder for pile driving construction.

[0019] Suction cylinders 44 are installed at the four corners of the anti-sinking platform 41, with the four suction cylinders 44 correspondingly distributed at the four corners of the platform 41. Each suction cylinder 44 is a sealed cylinder with its top opening sealed by a sealing plate. A pressure sensor 410 communicating with the internal space is installed on each suction cylinder 44, and the pressure sensor 410 displays the positive and negative pressure values ​​inside the suction cylinder 44.

[0020] It also includes a hydraulic control valve 55, one end of which is connected to the suction cylinder 44, and the other end of the hydraulic control valve 55 is connected to a water pump 53. When the hydraulic control valve 55 is turned on, the water pump 53 draws seawater out of the suction cylinder 44 to create a negative pressure, allowing the suction cylinder 44 to sink to the seabed under negative pressure, thus vertically inserting the suction cylinder 44 into the seabed. The water pump 53 is equipped with a protective frame for protection.

[0021] Four suction cylinders 44, distributed at the four corners of the work anti-sinking platform 41, are vertically inserted into the seabed under negative pressure for force support, reducing the contact length between the suction cylinders 44 and the seawater currents, and providing a static working environment for the work anti-sinking platform 41 that is not easily affected.

[0022] The hydraulic control valve 55 is connected to an oil pump via an oil pipe 54. The oil pump is connected to an oil tank 52. The oil tank 52 is mounted on the anti-sinking platform 41 via a mounting bracket 51. The mounting bracket 51, oil pump, oil tank 52, oil pipe 54 and hydraulic control valve 55 constitute a hydraulic control system 5. The hydraulic control system 5 controls the hydraulic control valve 55 to open or close.

[0023] The four corners of the anti-sinking platform 41 are provided with suction cylinder mounting ports 43, which allow suction cylinders 44 to pass through and be placed in a limited position, and the suction cylinders 44 are fixed to the anti-sinking platform 41.

[0024] The anti-sinking platform 41 is welded and fixed at its four corners with platform lifting lugs 411, which facilitates the connection of the anti-sinking platform 41 to the hoisting or towing cable through the platform lifting lugs 411.

[0025] The anti-sinking platform 41 has a second pile hole 42 in the middle for the pile foundation cylinder to be installed through. The diameter of the second pile hole 42 is larger than that of the pile foundation cylinder. Platform base mounting plates 47 are welded and fixed to the top left and right sides of the anti-sinking platform 41 located at the second pile hole 42. A seventh double-ear plate 48 is welded and fixed to the platform base 3. The seventh double-ear plate 48 and the platform base 3 can be rotatably installed back and forth. Hydraulic cylinder mounting plates 45 are welded and fixed to the top front and rear of the anti-sinking platform 41 located at the second pile hole 42. A sixth double-ear plate 46 is welded and fixed to the hydraulic cylinder mounting plate 45. The sixth double-ear plate 46 is used to be rotatably installed back and forth with the adjusting hydraulic cylinder B39. The top of the adjusting hydraulic cylinder B39 and the platform base 3 can be rotatably installed back and forth. There are four adjusting hydraulic cylinders B39, which are installed in pairs at intervals at the front and rear of the anti-sinking platform 41. The adjusting hydraulic cylinders B39 provide telescopic power to push the platform base 3 to rotate back and forth on the seventh double-ear plate 48.

[0026] This application provides an anti-sinking plate for an underwater pile stabilizing frame for pile driving, comprising: an anti-sinking work platform 41 for equipment installation and personnel to walk on; The anti-sinking platform 41 is equipped with drainage holes 49; after the waves hit the anti-sinking platform 41, the seawater is drained through multiple spaced drainage holes 49.

[0027] The present application discloses a pile-holding guide tube for an underwater pile stabilizing frame for pile driving, comprising: a guide tube 1 consisting of two semi-circular guide tubes 11, which can hold the pile foundation tube body after the two semi-circular guide tubes 11 are closed relative to each other; a guide inclined body 14 is fixedly installed at the top opening of each semi-circular guide tube 11, and the guide inclined body 14 provides guidance when the pile foundation tube body is connected and installed.

[0028] Multiple wear-resistant blocks 18 are fixedly installed on the inner wall of the semi-circular guide cylinder 11 at intervals. The wear-resistant blocks 18 can be made of rubber blocks.

[0029] When the two semi-circular guide cylinders 11 hold the pile foundation cylinder under stress, multiple wear-resistant blocks 18 on the inner wall of the two semi-circular guide cylinders 11 come into contact with the outer peripheral surface of the pile foundation cylinder at multiple points, thus avoiding the situation where the pile foundation cylinder is subjected to stress at a single point of contact.

[0030] Multiple wear-resistant blocks 18, spaced apart, are fixedly installed on the inner wall of the semi-circular guide cylinder 11 via vertical ribs 12, horizontal ribs 13, and limiting plates 17. The vertical ribs 12 are multiple vertically spaced and welded to the inner and outer walls of the semi-circular guide cylinder 11. The horizontal ribs 13 are multiple horizontally spaced and welded to the inner and outer walls of the semi-circular guide cylinder 11. The vertical ribs 12 and horizontal ribs 13 are perpendicularly distributed and intersected. The limiting plates 17 are welded to the inner wall of the semi-circular guide cylinder 11 at the point where the vertical ribs 12 and horizontal ribs 13 are perpendicular. The bottom surface of the limiting plates 17 is perpendicular to the horizontal ribs 13. There is a gap between the limiting plates 17 and the vertical ribs 12. The wear-resistant blocks 18 are clamped and fixed in the gap between the limiting plates 17 and the vertical ribs 12. The wear-resistant blocks 18 are radially higher than the vertical ribs 12 on the inner wall of the semi-circular guide cylinder 11.

[0031] The vertical height of the limiting plate 17 is lower than half of the vertical rib 12, presenting a notch, which facilitates the removal of the wear-resistant block 18 from the notch at the top of the limiting plate 17 for replacement.

[0032] The outer wall of the semicircular guide cylinder 11 located on the guide inclined body 14 is fixed with guide cylinder lifting lugs 16. There are two or more guide cylinder lifting lugs 16 on the outer periphery of each semicircular guide cylinder 11. The guide cylinder lifting lugs 16 are welded and fixed to the outer wall of the semicircular guide cylinder 11 at intervals. The semicircular guide cylinder 11 is hoisted and installed onto the platform base 3 by connecting the hoisting cable of the hoisting equipment through the guide cylinder lifting lugs 16.

[0033] The bottom of the guide tube lifting lug 16 is fixedly connected to the two layers of transverse ribs 13 at an intersection.

[0034] The bottom of the semicircular guide cylinder 11 is welded and fixed with a connecting piece 15 in the shape of an arc plate. Two or more connecting pieces 15 are spaced apart. The semicircular guide cylinder 11 is rotatably mounted to the third double-eared plate 34 of the platform base 3 via the connecting pieces 15. A rotating shaft is installed between the connecting pieces 15 and the third double-eared plate 34 to achieve rotatable mounting. The semicircular guide cylinder 11 is mounted on the platform base 3 externally via a telescopic adjusting cylinder A26 and a force-bearing guide cylinder linkage device 2. When the adjusting cylinder A26 provides push-pull force, the force is transmitted to the semicircular guide cylinder 11 through the guide cylinder linkage device 2. The semicircular guide cylinder 11 contacts the outer circumference of the pile foundation cylinder at multiple points through multiple wear-resistant blocks 18. Each semicircular guide cylinder 11 has one guide cylinder linkage device 2 and two adjusting cylinders A26. The adjusting cylinders A26 provide push-pull force, allowing the semicircular guide cylinder 11 to rotate left and right relative to the platform base 3 to open or close.

[0035] The platform base 3 of the underwater pile stabilizing frame for pile driving of this application includes: The platform plate 31 in the middle is provided with the first pile hole 35, and the first pile hole 35 is used for the pile foundation cylinder gap penetration pile driving construction.

[0036] The platform plate 31 is provided with a weight-reducing structural hole 36. The platform plate 31 at the structural hole 36 has a rectangular clamping beam 361. A cylinder base 32 is clamped in the rectangular clamping beam 361. The cylinder base 32 has a rectangular slot that is interference-fitted with the rectangular clamping beam 361 and clamped tightly. The cylinder base 32 is in contact with the side plane of the platform plate 31 at the rectangular clamping beam 361. A second double-eared plate 33 inclined towards the first pile hole 35 is fixed on the cylinder base 32. An adjusting cylinder A26 is rotatably mounted on the second double-eared plate 33 through a hinge shaft.

[0037] The force generated by the extension and retraction of the hydraulic cylinder A26 is transmitted to the inclined second double-ear plate 33. The second double-ear plate 33 tends to rotate around the rectangular clamping beam 361. The hydraulic cylinder base 32 contacts the side plane of the platform plate 31 at the rectangular clamping beam 361, and the rectangular slot of the hydraulic cylinder base 32 is interference-fitted with the rectangular clamping beam 361, which restricts the hydraulic cylinder base 32 from moving along the rectangular clamping beam 361. When it is necessary to adjust the position of the hydraulic cylinder base 32 on the rectangular clamping beam 361, An upward thrust is applied to the vertical bottom surface of the cylinder base 32, causing the rectangular slot of the cylinder base 32 to disengage from the rectangular clamping beam 361 for position adjustment. After adjustment, the rectangular slot of the cylinder base 32 is then pressurized to fit the rectangular clamping beam 361, restoring the contact between the cylinder base 32 and the side plane of the platform plate 31 at the rectangular clamping beam 361. This allows the cylinder base 32 to serve as the mounting base for adjusting the cylinder A26 on the rectangular clamping beam 361 for position adjustment.

[0038] The platform plate 31 has a fourth double-ear eye plate 37 welded and fixed to the bottom surface of the left and right sides. The fourth double-ear eye plate 37 is hinged to the seventh double-ear eye plate 48 of the working anti-sinking platform 41 by means of a pin.

[0039] The platform plate 31 is welded and fixed to the bottom surface of the front and rear sides with a fifth double eye plate 38. The top of the adjusting cylinder B39 and the fifth double eye plate 38 are hinged to each other by a pin. The adjusting cylinder B39 and the sixth double eye plate 46 of the working anti-sinking platform 41 can be installed to rotate back and forth.

[0040] This application discloses an angle-shifting guide tube for underwater pile stabilization frames used in pile foundation driving, comprising: The semicircular guide cylinder 11 is used to hold the pile foundation cylinder and provide multiple points of contact to distribute the force. There are two semicircular guide cylinders 11 that can be unfolded or closed. The semicircular guide cylinder 11 is fixedly installed with a guide cylinder linkage device 2. The guide cylinder linkage device 2 includes an inclined rod 23 that is fixedly connected to the transverse rib 13 on the outer wall of the top of the semicircular guide cylinder 11. There are two inclined rods 23 that are spaced apart. The bottom of each inclined rod 23 is welded and fixed with a first double eye plate 25. The first double eye plate 25 is rotatably hinged to the telescopic end of the adjusting cylinder A26.

[0041] A lower transverse rod 21 is welded and fixed to the bottom of the oblique rod 23 of the first double-ear plate 25. The lower transverse rod 21 is fixedly connected to the transverse rib 13 on the lower outer wall of the semicircular guide cylinder 11. The middle part of the oblique rod 23 is fixedly connected to the transverse rib 13 on the middle outer wall of the semicircular guide cylinder 11 through the upper transverse rod 22.

[0042] The lower transverse rod 21, the connector 15, and the transverse rib 13 at the bottom of the semi-circular guide cylinder 11 are connected and fixed together.

[0043] When adjusting the extension and retraction of hydraulic cylinder A26 to provide push and pull force, the push and pull force of hydraulic cylinder A26 is distributed to the top and lower part of the semi-circular guide cylinder 11 through the diagonal rod 23, the upper horizontal rod 22, and the lower horizontal rod 21 respectively for push and pull.

[0044] The two semi-circular guide cylinders 11 correspond to the two guide cylinder linkage devices 2 and the four adjusting oil cylinders A26, respectively.

[0045] This application discloses an adjusting cylinder for an underwater pile stabilizing frame used for pile driving, specifically used to construct adjusting cylinders A26 and B39, comprising: A cylinder sleeve 61 with a connecting ring 62 at one end has a travel space 631 inside. A retaining ring 63 is fixedly connected to the inner wall of the travel space 631. A piston 64 is slidably installed between the retaining ring 63 and the right inner wall of the travel space 631, and the piston 64 divides the space between the retaining ring 63 and the travel space 631. The piston 64 is fixed with a piston rod 65, which can slide through the other end of the cylinder sleeve 61. The piston rod 65 is provided with a second shaft hole 66. The cylinder sleeve 61, located between the retaining ring 63 and the left inner wall of the travel space 631, is provided with an inlet 67 and an outlet 68. The inlet 67 and the outlet 68 are correspondingly distributed vertically at the same radial cross-section at the same end of the cylinder sleeve 61. The connecting ring 62 is provided with a first shaft hole 69.

[0046] The first shaft hole 69 and the second shaft hole 66 are located at both ends of the adjusting cylinder, allowing the shaft to pass through when the adjusting cylinder is hinged. Valves can be installed on the inlet 67 and outlet 68 to control their opening or closing.

[0047] Since the inlet 67 and outlet 68 are located on the same radial cross section at the same end of the cylinder sleeve 61, the hydraulic oil pipes are led out from the same end of the cylinder sleeve 61 after connecting the valves at the inlet 67 and outlet 68 using hydraulic oil pipes for easy arrangement.

[0048] Taking the adjustment of the hydraulic cylinder extension and retraction as an example, with four adjustment hydraulic cylinders A26 distributed in pairs on the outer wall of the two semi-circular guide cylinders 11; when the two semi-circular guide cylinders 11 need to be retracted and closed, the inlet 67 is opened to input oil, the outlet 68 is closed, the oil in the space to the left of the retaining ring 63 increases and the pressure increases, the piston 64 pushes the piston rod 65 to extend; when the adjustment hydraulic cylinder retracts and becomes shorter, mainly using gravity, the outlet 68 is opened to discharge the oil in the space to the left of the retaining ring 63. When the pile foundation cylinder is still inside the two semi-circular guide cylinders 11, the wear-resistant block 18 pushes the semi-circular guide cylinders 11 apart by elasticity and causes them to tilt. When the pile foundation cylinder is driven into the pile, the semi-circular guide cylinders 11 are slightly tilted by manually applying force with a crowbar. The tilted semi-circular guide cylinders 11 use gravity to push the piston rod 65 to retract the piston 64.

[0049] When adjusting the extension and retraction of the hydraulic cylinders, taking the installation of four adjusting hydraulic cylinders B39 at the bottom of the platform base 3 as an example, the weight of the platform base 3 is used to push the piston rod 65 to retract the piston 64.

[0050] During the sinking process of the pile foundation cylinder in the first pile hole 35 and the second pile hole 42, after it is disturbed by the water flow and becomes deviated, the adjusting cylinder A26 pushes the two semi-circular guide cylinders 11 close together and hug the pile foundation cylinder on the platform seat 3 through the guide cylinder linkage device 2; the adjusting cylinder A26 rotates the semi-circular guide cylinders 11 left and right on the platform seat 3 to correct the pile foundation cylinder left and right; the adjusting cylinder B39 rotates the platform seat 3 back and forth on the working anti-sinking platform 41 to correct the pile foundation cylinder back and forth.

[0051] The anti-sinking platform 41 and platform plate 31 are equipped with level sensors.
