Description

Technical Field

[0001] This application relates to the field of building engineering technology, and more specifically, to a pile driving positioning device. Background Technology

[0002] In offshore pile driving construction, the pile positioning device is a crucial component that provides precise guidance for the pile. Most existing pile positioning devices employ an integrated fixed structure, with the spacing and inner diameter of their guiding mechanisms specifically designed for the pile diameter and spacing of a particular project (such as a specific type of jacket). This customized design leads to extremely poor versatility; once faced with engineering requirements of different pile diameters or spacings, the device cannot be reused and must be remanufactured, significantly increasing construction costs and extending project cycles.

[0003] Therefore, how to improve the versatility of pile driving positioning devices has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a pile driving positioning device to improve the versatility of the pile driving positioning device.

[0005] A pile driving positioning device, comprising:

[0006] Main framework;

[0007] Multiple guide cylinders, each guide cylinder having an inlet portion communicating with the top of the guide cylinder, and the inner diameter of the inlet portion gradually decreasing from the end away from the guide cylinder to the end closer to the guide cylinder until it is the same as the inner diameter of the guide cylinder.

[0008] Multiple connecting components are connected one-to-one between the guide cylinder and the main frame, and the length of the connecting components is adjustable so that the distance between the main frame and the guide cylinder is adjustable. The guide cylinder is used for the pipe pile to pass through.

[0009] In some embodiments, the connecting assembly includes a plurality of replaceable connectors with different preset lengths, the replaceable connectors being detachably connected to both the main frame and the guide cylinder, so as to adjust the spacing between the main frame and the guide cylinder by selectively connecting one of the replaceable connectors between the main frame and the guide cylinder.

[0010] In some embodiments, the main frame is provided with a connecting member, and the connecting member is provided with an insert hole for inserting the end of the replaceable connector.

[0011] In some embodiments, the connecting member has a first fixing hole, and the replaceable connector has a second fixing hole communicating with the first fixing hole, with the fixing member passing through the first fixing hole and the second fixing hole.

[0012] In some embodiments, the connection component includes:

[0015] A movable locking component passes through the first adjustment hole and the second adjustment hole, and fixes the movable mounting base on the main adjustment rod.

[0016] In some embodiments, the movable mounting base is provided with a sliding mating hole, and the inner wall of the sliding mating hole is provided with a snap-fit ​​protrusion.

[0017] The adjusting main rod passes through the sliding fitting hole, and the adjusting main rod is provided with an avoidance groove for the snap-fit ​​protrusion to be inserted.

[0019] In some embodiments, the dimension of the inlet portion along the axis of the guide cylinder is the length dimension, and the length of the inlet portion on the side closer to the main frame is greater than the length on the side farther from the main frame.

[0021] Multiple columns are arranged at intervals, and each column is connected to a connecting component and corresponds to a guide cylinder.

[0022] Multiple suction cylinders are provided, with each suction cylinder corresponding to the bottom of each column.

[0024] Multiple diagonal braces are provided, with each end of the diagonal brace connected to a different column, and the diagonal braces are arranged at an angle relative to the crossbeam.

The top of each guide cylinder has an inlet portion communicating with it, and the inner diameter of the inlet portion gradually decreases from the end furthest from the guide cylinder to the end closest to it, until it matches the inner diameter of the guide cylinder.

[0039] The core of this application is to disclose a pile driving positioning device to improve the versatility of pile driving positioning devices.

[0040] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0041] Combination Figures 1-7The pile driving positioning device disclosed in this application includes a main frame 100, a plurality of guide cylinders 200 and a plurality of connecting components 210. The top of the guide cylinder 200 is provided with an inlet portion 201 communicating with the guide cylinder 200. The inner diameter of the inlet portion 201 gradually decreases from the end away from the guide cylinder 200 to the end closer to the guide cylinder 200 until it is the same as the inner diameter of the guide cylinder 200, thereby expanding the initial inlet range of the pipe pile 300 and facilitating the inlet of the pipe pile 300 into the guide cylinder 200. The two ends of the connecting components 210 are respectively connected to the guide cylinder 200 and the main frame 100, and the length of the connecting components 210 is adjustable so that the distance between the main frame 100 and the guide cylinder 200 is adjustable. The guide cylinder 200 is used for the pipe pile 300 to pass through.

[0042] Before installation, the length of the connecting component 210 is adjusted according to the pile spacing of the pipe piles 300, so that the distance between the guide cylinder 200 and the main frame 100 meets the pile spacing requirements of the pipe piles 300. During installation, the main frame 100 is first dragged to the piling position, and then the bottom of the main frame 100 is driven into the seabed to the design depth. After leveling, the installation accuracy is achieved, and the installation of the pile driving positioning device is completed. After the installation of the pile driving positioning device is completed, the pile driving operation can be carried out, that is, the pipe piles 300 are driven into each guide cylinder 200 respectively.

[0043] Compared with the prior art, the pile driving positioning device disclosed in this application makes the length of the connecting component 210 adjustable, so that the relative position of the guide cylinder 200 and the main frame 100 can be adjusted. This makes the pile driving positioning device applicable to pile driving operations with different pile spacings within a certain range, with strong versatility and good economy.

[0044] Specifically, the connection component 210 can be connected to the guide cylinder 200 and the main frame 100 by means of bolt connection, welding, clamp connection, etc., and this application does not limit this.

[0045] In some embodiments disclosed in this application, combined with Figure 5 The connecting component 210 includes multiple replaceable connectors 217 with different preset lengths. The replaceable connectors 217 are connected to the main frame 100 and the guide cylinder 200 by detachable methods such as clamp connection, bolt connection, and pin connection. The distance between the main frame 100 and the guide cylinder 200 can be adjusted by selectively connecting one of the replaceable connectors 217 between the main frame 100 and the guide cylinder 200.

[0046] Furthermore, combined Figure 5A connecting member 218 is provided on the main frame 100, and the connecting member 218 is provided with an insert hole for the end of the replaceable connector 217 to be inserted. The cross-sectional shape of the replaceable connector 217 and the insert hole are compatible, and can be circular, rectangular or other shapes. The structure is simple, and the assembly process is intuitive and convenient, and easy to maintain and disassemble.

[0047] To improve the reliability of the connection, a first fixing hole can be opened on the connecting member 218, and a second fixing hole communicating with the first fixing hole can be opened on the replaceable connector 217. The fixing member can pass through the first fixing hole and the second fixing hole, thereby further fixing the connecting member 218 and the replaceable connector 217 reliably through the fixing member.

[0048] In some other embodiments disclosed in this application, the connecting assembly 210 includes an adjusting main rod 219, a movable mounting base 220, and a movable locking member 221. One end of the adjusting main rod 219 is connected to the main frame 100, and the adjusting main rod 219 is provided with a plurality of first adjusting holes, which are spaced apart along the axial direction of the adjusting main rod 219. The movable mounting base 220 is slidably disposed on the adjusting main rod 219 and has at least one second adjusting hole communicating with the first adjusting holes. The guide cylinder 200 is connected to the movable mounting base 220. The movable locking member 221 can pass through the first adjusting hole and the second adjusting hole to fix the movable mounting base 220 at different positions on the adjusting main rod 219, thereby realizing the adjustment of the distance between the main frame 100 and the guide cylinder 200.

[0049] A further optimized design includes a sliding fit hole through the movable mounting base 220. The adjusting main rod 219 can pass through this sliding fit hole, and the cross-sectional shape of the sliding fit hole and the adjusting main rod 219 are compatible, thereby achieving a reliable sliding fit between the two. For example, the cross-sectional shape of the sliding fit hole can be circular, rectangular, or other shapes; this application does not impose any limitations on this. Figure 7 In some embodiments, the cross-sectional shape of the sliding mating hole is circular, and a snap-fit ​​protrusion 222 is provided on the inner wall of the sliding mating hole. Correspondingly, an avoidance groove is provided on the adjusting main rod 219 for the snap-fit ​​protrusion 222 to be inserted. Thus, the rotation of the movable mounting seat 220 relative to the adjusting main rod 219 is restricted by the cooperation of the snap-fit ​​protrusion 222 and the avoidance groove, thereby ensuring the consistency of the posture of the guide cylinder 200 during the adjustment process.

[0050] In some other embodiments disclosed in this application, the connecting component 210 includes a telescopic rod, and the two ends of the telescopic rod are respectively connected to the main frame 100 and the guide cylinder 200, so as to realize the connection between the main frame 100 and the guide cylinder 200 by telescopic rod extension and retraction. It is highly flexible and can adapt to different size installation requirements and usage scenarios. Moreover, the telescopic rod has a simple structure, is easy to install and debug, and has strong versatility.

[0051] For example, in combination Figure 4 The aforementioned telescopic pole may include a first pole body 211, a second pole body 212, and a locking member 213. The first pole body 211 has multiple first locking holes 211a, which are spaced apart along the extension direction of the first pole body 211. The second pole body 212 is sleeved with the first pole body 211 and can slide relative to it. The second pole body 212 has multiple second locking holes 212a, which are spaced apart along the extension direction of the second pole body 212. The locking member 213 passes through the first locking holes 211a and the second locking holes 212a to lock the relative position of the first pole body 211 and the second pole body 212, thereby adapting to various application scenarios with different pile spacings. The structure is simple and reliable.

[0052] To ensure structural strength, both the first rod 211 and the second rod 212 can be hollow structures. Hollow rods have higher moments of inertia and section moduli than solid rods, resulting in superior strength and stiffness under bending and torsional loads. This achieves lightweighting while ensuring the structural mechanical performance. It should be noted that the cross-sectional shapes of the first rod 211 and the second rod 212 can be rectangular, circular, etc., and their cross-sectional shapes are compatible to form a circumferential constraint. This effectively prevents relative rotation of the first rod 211 and the second rod 212 during expansion and contraction, thus ensuring the alignment of the first locking hole 211a and the second locking hole 212a and guaranteeing structural reliability.

[0053] In some embodiments disclosed in this application, combined with Figure 2 and Figure 3 The connecting assembly 210 includes a first connecting member 214, a second connecting member 215, and at least one adjusting member 216. The first connecting member 214 is connected to the guide cylinder 200; the second connecting member 215 is connected to the main frame 100. The first connecting member 214 and the second connecting member 215 are directly connected, or the first connecting member 214 and the second connecting member 215 are connected through at least one adjusting member 216, so that the distance between the first connecting member 214 and the second connecting member 215 can be adjusted by changing the number of adjusting members 216. This embodiment can realize discrete adjustment of the distance between the guide cylinder 200 and the main frame 100. Specifically, the adjusting member 216 has a standardized length, so that a preset, repeatable distance value can be achieved by increasing or decreasing the number of adjusting members 216, ensuring the consistency and interchangeability of the assembly, avoiding the need to customize special parts for each distance, and having strong versatility. In addition, since all adjusting members 216 are standardized parts with the same specifications, manufacturing and supply chain management are greatly simplified, and the cost of a single part can be effectively reduced through large-scale production.

[0054] In some embodiments, combined with Figure 3 The first connecting member 214 is provided with a first connecting flange 214a, and the second connecting member 215 is provided with a second connecting flange 215a. The adjusting member 216 includes an adjusting body 216a, a third connecting flange 216b, and a fourth connecting flange 216c. The adjusting body 216a is a hollow tube structure to ensure structural strength. The third connecting flange 216b is connected to the first end of the adjusting body 216a and is bolted to the first connecting flange 214a or the fourth connecting flange 216c of the adjacent adjusting member 216. The fourth connecting flange 216c is connected to the second end of the adjusting body 216a and is bolted to the second connecting flange 215a or the third connecting flange 216b of the adjacent adjusting member 216. In this embodiment, a strong axial clamping force is formed at the connection of the connecting component 210 through the rigid end face of the flange structure and the pre-tightening force of the bolts, ensuring the structural integrity of the connecting component 210 when subjected to axial tensile and bending loads; and this connection method can realize quick disassembly and modular maintenance between the first connecting component 214 and the second connecting component 215 and the adjusting component 216, as well as between the adjusting component 216, without the need for irreversible operations such as on-site welding.

[0055] Furthermore, one of the first connecting flange 214a and the third connecting flange 216b is provided with a first positioning ring groove, and the other of the first connecting flange 214a and the third connecting flange 216b is provided with a first annular positioning protrusion that can be embedded in the first positioning ring groove. The engagement of the first positioning ring groove and the first annular positioning protrusion enables rapid self-centering and circumferential anti-misalignment between the first connecting flange 214a and the third connecting flange 216b, greatly simplifying the assembly operation, shortening the alignment time, and effectively avoiding uneven bolt force caused by installation deviation. In addition, before bolt pre-tightening, the embedding structure of the first positioning ring groove and the first annular positioning protrusion can withstand some shear force and torque, providing support for temporary fixation, thereby improving the safety and convenience of operation under complex working conditions.

[0056] Similarly, one of the second connecting flange 215a and the fourth connecting flange 216c is provided with a second positioning ring groove, and the other of the second connecting flange 215a and the fourth connecting flange 216c is provided with a second annular positioning protrusion that can be embedded in the second positioning ring groove, so as to realize the positioning and fitting between the second connecting flange 215a and the fourth connecting flange 216c. The adjusting members 216 can also be positioned and fitted with each other through the cooperation of the protrusion and the groove, which will not be described in detail here.

[0057] To accommodate the installation of pipe piles 300 with different diameters within a certain range, the guide cylinder 200 and the connecting assembly 210 are connected in a detachable manner. This decouples the guiding function from the main connection function, forming a replaceable modular system. By replacing the guide cylinder 200 with one of different inner diameters, it can accurately adapt to pipe piles 300 with different diameters. This modular design avoids customizing an entire set of equipment for each working condition, improving versatility and economy. For example, the connecting assembly 210 may include clamps for fixing the guide cylinder 200, or it may include pins, bolts, or other connecting parts for fixing to the pin shaft, making on-site replacement of the guide cylinder 200 quick and convenient, improving construction efficiency and equipment turnover rate.

[0058] Combination Figure 1 and Figure 2 The guide section 201 is coaxially and connected to the guide cylinder 200. The length of the guide section 201 along the axis of the guide cylinder 200 is defined as the length dimension. The length of the guide section 201 on the side closer to the main frame 100 is greater than the length on the side farther from the main frame 100. The longer side can provide an earlier initial contact point and a longer straightening stroke, so that a continuous and gradual lateral force can be applied for attitude correction in the early stage of the lowering of the pipe pile 300. Although the shorter side contacts the pipe pile 300 later, its structure ensures that the pipe pile 300 will be effectively constrained once it makes contact at the end of the guide, which significantly improves the fault tolerance and work efficiency of the pipe pile 300 introduction process.

[0059] Combination Figure 2 In some embodiments disclosed in this application, the main frame 100 is a truss structure and includes columns 110, suction cylinders 120, crossbeams 130, and diagonal braces 140. There are multiple columns 110, suction cylinders 120, crossbeams 130, and diagonal braces 140. The multiple columns 110 are spaced apart and arranged vertically to form a basic support frame. Each column 110 is connected to a connecting component 210 and corresponds to at least one guide cylinder 200. Each suction cylinder 120 is correspondingly set at the bottom of each column 110 to achieve foundation anchoring. The crossbeam 130 is connected between two columns 110 and is arranged perpendicular to the column 110 to form a horizontal force transmission path. The two ends of the diagonal brace 140 are connected to different columns 110 respectively, and the diagonal brace 140 is arranged at an inclination relative to the crossbeam 130 so that the columns 110, crossbeams 130, and diagonal braces 140 constitute a triangular stable unit. The main frame 100 effectively improves its anti-overturning ability and overall stiffness under complex working conditions through the vertical load transfer of the suction cylinder 120, the lateral rigid constraint of the crossbeam 130, and the geometric stability of the diagonal brace 140.

[0060] When installing the main frame 100, first drag the main frame 100 to the piling position, then insert the suction cylinder 120 into the seabed to the design depth. After leveling, the installation accuracy is achieved, and the entire installation process is completed. Finally, the pipe pile 300 can be introduced into the guide cylinder 200 to complete the pile driving operation.

[0061] Specifically, the main frame 100 includes at least three columns 110, crossbeams 130, and suction cylinders 120. The columns 110 are arranged in an array to construct a spatial truss system. The columns 110, diagonal braces 140, and suction cylinders 120 can all be formed by welding circular tubes. This uniform circular tube cross-section not only optimizes material distribution and improves the bending and compressive strength of the components, but also achieves rigid connection of nodes through welding, ensuring continuous transmission and effective distribution of loads among the columns 110, crossbeams 130, and diagonal braces 140. This significantly enhances the stiffness and stability of the structure in the horizontal and vertical directions, allowing the positioning frame to more evenly transfer the upper load to the foundation. The crossbeams 130 can be box girder structures welded from plates, thus achieving higher bending and torsional resistance with a lighter weight, effectively resisting external load deformation. At the same time, their hollow internal design facilitates pipeline layout and later maintenance, and makes the main frame 100 lighter, stronger, and more durable overall.
