Description

Technical Field

[0001] This utility model relates to the field of levelness detection technology, specifically to an auxiliary device for detecting the levelness of the top of offshore pipe piles. Background Technology

[0002] Offshore pipe piles are the core support structure in marine engineering, mainly used in offshore wind power, dock construction, deep-sea aquaculture and other fields. They are driven by a pile driver to sink and bury the pipe piles on the seabed, so that the pipe piles are stably supported on the sea surface. Before the pile is driven by the pile driver, the pipe pile will sink a certain distance by its own weight, and workers need to ride in a basket to reach the top of the pipe pile to check the levelness of the top of the pipe pile.

[0003] Existing methods for detecting the levelness of offshore pipe pile tops typically involve directly measuring the top plane of the pipe pile using instruments such as levels. However, sometimes the top plane of the pipe pile has errors and is not perpendicular to the centerline of the pipe pile. Directly measuring the top plane of the pipe pile makes it impossible to determine the specific vertical direction of the pipe pile. After pile driving, the vertical deviation due to the difference in angle will affect the overall project. Furthermore, most pipe piles are typically designed with a thinner top and thicker bottom to improve stability, making it difficult to determine their centerline, which affects the accuracy and reliability of the pipe pile driving operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide an auxiliary device for detecting the levelness of the top of a marine pipe pile. This device can determine the centerline of the pipe pile at the top of the pile, thereby better detecting the levelness of the pipe pile.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] An auxiliary device for detecting the levelness of the top of offshore pipe piles includes a levelness detector and a suspended platform. A detection slot is provided in the middle of the bottom plate of the suspended platform. The device also includes:

[0007] The limiting support device passes through the detection slot and rests on the bottom plate of the basket. The bottom is equipped with an unfolding module, and six support rods are evenly arranged around the circumference of the unfolding module. The other end of each support rod is equipped with an inner wall positioning module. The six support rods are rotated synchronously through the unfolding module, so that each inner wall positioning module abuts against the inner wall of the pipe pile, and the limiting support device coincides with the center line of the pipe pile.

[0008] The operating module is located on top of the limiting support device, and the levelness detector is horizontally mounted on the operating module.

[0009] As an improvement, the limiting support device includes a support base and a support plate. The support base is arranged in the detection slot and a connecting rod is erected at the bottom. A movable slot is provided through the left and right sides of the support base. The support plate is arranged in the movable slot. A spring is provided between the top and the support base, and both ends are placed on the bottom plate of the hanging basket to support the support base.

[0010] As an improvement, the unfolding module includes a synchronous flipping structure, which includes a connecting plate horizontally set at the bottom of the connecting rod. Six bearing seats are evenly arranged around the bottom, and a lifting rod is slidably arranged in the middle. The lifting rod is arranged vertically, and a rack is set on the outer side corresponding to each bearing seat. A gear that meshes with the corresponding rack is rotatably set on each bearing seat. After the lifting rod moves up and down, each gear rotates synchronously.

[0011] As an improvement, the unfolding module also includes a flip rod, a screw, and an unfolding motor. The unfolding motor is located at the bottom of the support base. The screw is arranged vertically, with one end threaded into the lifting rod and the other end connected to the drive shaft of the unfolding motor. The flip rod is a U-shaped rod with corresponding gears, and both ends are connected to the rotating shafts of the corresponding gears. After the screw rotates, the lifting rod moves up and down.

[0012] As an improvement, the inner wall positioning module includes a positioning seat and an abutment rod. One side of the positioning seat is connected to the flip rod via a support rod, and the other side is hinged to the middle of the abutment rod. Rollers are provided at both ends of the abutment rod, and a spring is provided between one end and the positioning seat.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. This utility model has six support rods evenly arranged along the circumference, and the end of each support rod is provided with an inner wall positioning module. After each support rod is unfolded, the inner wall positioning modules that abut against the inner wall of the pipe pile are arranged in a regular hexagon, thereby obtaining a circular cross section of the pipe pile, determining the position of the center line of the pipe pile, and assisting the workers on the suspended platform to detect the levelness of the pipe pile, making the detection effect more accurate.

[0015] 2. This utility model is equipped with a limiting support device, which can support the present invention while adjusting its position and direction. This allows the center line to be determined without being affected by the horizontal plane of the top of the pipe pile, and reduces the weight used during operation, making it more convenient and labor-saving to use.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] An auxiliary device for detecting the levelness of the top of offshore pipe piles, such as Figure 1As shown, the system includes a suspended platform 1 with a grid bottom plate and a circular detection slot 11 in the center. A limiting support device 2 is installed inside the detection slot 11. The top of the limiting support device 2 rests on the bottom plate of the suspended platform 1, and an unfolding module 4 is installed at the bottom. Six support rods 5 are evenly arranged along the circumference of the unfolding module 4. An inner wall positioning module 6 is installed at the other end of each support rod 5. An operation module 3 is installed on the top of the limiting support device 2, and a levelness detector 7 is horizontally installed on the top of the operation module 3. The six support rods 5 are rotated synchronously through the unfolding module 4, so that each inner wall positioning module 6 abuts against the inner wall of the pipe pile, and the limiting support device 2 coincides with the center line of the pipe pile.

[0026] like Figure 2 , Figure 3 , Figure 6 As shown, the limiting support device 2 includes a support base 21 and a support plate 22. The support base 21 is arranged in the detection slot 11, and a connecting rod 25 is erected at the bottom. A movable slot 23 is provided through the left and right sides of the support base 21. The support plate 22 is arranged in the movable slot 23. A spring 24 is provided between the top and the support base 21, and both ends are placed on the bottom plate of the hanging basket 1.

[0027] like Figure 3 , Figure 4 As shown, the unfolding module 4 includes a synchronous flipping structure 41, a flipping rod 42, a screw 44, and an unfolding motor 43. The synchronous flipping structure 41 includes a connecting plate 411, which is horizontally arranged at the bottom of the connecting rod 25. Six bearing seats 414 are evenly arranged circumferentially at the bottom, and a lifting rod 412 is slidably arranged in the middle. The lifting rod 412 is arranged vertically, and a rack 413 is arranged on the outer side corresponding to each bearing seat 414. A gear 415 that meshes with the corresponding rack 413 is rotatably arranged on each bearing seat 414. The unfolding motor 43 is arranged at the bottom of the support base 21. The screw 44 is arranged vertically, with one end threaded to the lifting rod 412 and the other end connected to the drive shaft of the unfolding motor 43. The flipping rod 42 is a U-shaped rod arranged corresponding to the gear 415, and both ends are connected to the rotating shaft of the corresponding gear 415. After the unfolding motor 43 is started, it drives the screw 44 to rotate, and the lifting rod 412 moves up and down, so that each gear 415 drives the corresponding flipping rod 42 to rotate synchronously.

[0028] like Figure 3 , Figure 5 As shown, the inner wall positioning module 6 includes a positioning seat 61 and an abutment rod 62. One side of the positioning seat 61 is connected to the flip rod 42 via a support rod 5, and the other side is hinged to the middle of the abutment rod 62. Rollers 63 are respectively provided at both ends of the abutment rod 62, and a second spring 64 is provided between the upper end and the positioning seat 61. Before the inner wall positioning module 6 abuts against the inner wall of the pipe pile, the upper end of the abutment rod 62 flips towards the positioning seat 61 via the second spring 64, thereby ensuring that the two rollers 63 can abut against the inner wall of the pipe pile at the same time.

[0029] like Figure 1 , Figure 2 As shown, the operation module 3 includes a pole 31, which is erected directly above the support base 21 and connected to the support base 21 at the bottom. An operation handle 32 is provided at the top and is arranged horizontally to the left and right. A levelness detector 7 is provided at the top and a controller 33 is provided at the front. The controller 33 controls the unfolding motor 43. Triggers 34 are provided on the left and right sides respectively. The two triggers 34 control the unfolding motor 43 to rotate in the left and right directions and rotate in the opposite direction respectively. The controller 33, the levelness detector 7 and their usage methods are all existing mature technologies that are well known to the general public.

[0030] In the specific implementation of this embodiment:

[0031] The hoisting device moves the basket 1 above the top of the pipe pile and lowers it onto the pile. The operator uses the control handle 32 to control and adjust the position and direction of the lifting rod 412. Pressing the trigger 34 activates the deployment motor 43, causing the screw 44 to rotate. The lifting rod 412 moves up and down, causing each gear 415 to drive the corresponding tilting rod 42 and support rod 5 to rotate synchronously until all rollers 63 contact the inner wall of the pipe pile. At this point, the rollers 63 on the inner wall of the pipe pile are arranged in a regular hexagonal pattern on the upper and lower sides. Through these two regular hexagons, two circular cross-sections at different heights of the pipe pile are obtained, and the normals of the two circular cross-sections (i.e.,...) The center line of the pipe pile coincides with the screw 44, the limiting support device 2, and the upright 31. The levelness of the top of the pipe pile is tested by the levelness detector 7. After the test, the trigger 34 on the other side is pressed, the motor 43 is rotated in the opposite direction, and each support rod 5 is folded down and retracted. Finally, the basket 1 is moved away by the lifting device, and before it falls back to the ground, the equipment below the basket 1 is lifted. During the process, the limiting support device 2 is placed on the basket 1 through the support plate 22, and when each roller 63 is in contact with the inner wall of the pipe pile, the support seat 21 automatically adjusts its position and angle so that the center line of the support seat 21 coincides with the center line of the pipe pile.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
