Description

Technical Field

[0001] This utility model relates to the field of offshore piling technology, and in particular to an efficient offshore piling guidance device that is easy to position. Background Technology

[0002] When conducting pile driving operations at sea, the complex marine environment, including factors such as currents and waves, presents numerous challenges to the accuracy and efficiency of pile driving. Traditional offshore pile driving guidance devices have certain limitations in practical applications. Some guidance devices cannot flexibly adapt to the guidance requirements of piles with different diameters. When encountering piles of different specifications, it is often necessary to replace the entire guidance device or make complex adjustments, which not only consumes a lot of time and manpower but also leads to delays in construction progress. Although some devices can adapt to piles of different diameters, the positioning and adjustment are not precise enough. Under the action of external forces such as currents, the pile is prone to displacement, making it difficult to guarantee the verticality and positional accuracy of the pile driving, thus affecting the quality of the entire project. Therefore, developing an offshore pile driving guidance device that can efficiently position and adapt to various working conditions is of significant practical importance. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a marine transport fixing support for wind turbine towers.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An efficient offshore piling guidance device that is easy to position includes a supporting cylinder with a piling through hole on the upper end face of the supporting cylinder. Multiple guide roller assemblies are evenly distributed along the circumference inside the supporting cylinder, and each guide roller assembly can slide radially along the supporting cylinder. A power drive device is also provided on the supporting cylinder, which can drive all the guide roller assemblies to slide inward or outward simultaneously.

[0006] In some implementations, the guide roller assembly includes a sliding frame with a track on the end face of the support cylinder, the sliding frame sliding on the track, and guide rollers mounted on the sliding frame, with all guide rollers surrounding to form a guide channel.

[0007] In some implementations, the guide roller is rotatably mounted on the sliding frame, and the guide roller has an arc-shaped concave structure in the middle.

[0008] In some implementations, the power drive device includes a rotating ring rotatably mounted on the end face of the supporting cylinder, a gear ring provided on the outer wall of the rotating ring, a motor provided on the outside of the supporting cylinder, a gear that can mesh with the gear ring provided on the output shaft of the motor, guide rods provided on each of the sliding frames, a straight slide groove extending radially along the end face of the supporting cylinder, and an oblique slide groove provided on the rotating ring, with the guide rods respectively passing through the straight slide groove and the oblique slide groove.

[0009] In some implementations, an annular guide rail is provided on the end face of the supporting cylinder, and an annular slider that slides within the annular guide rail is provided at the lower end of the rotating ring.

[0010] In some implementations, the guide roller assembly is provided in four groups evenly distributed along the circumference.

[0012] In some implementations, a mounting base plate is provided on one side of the supporting cylinder, and the mounting base plate is provided with a plurality of mounting through holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The guiding device in this structure has multiple guide roller assemblies evenly distributed along the circumference inside the supporting cylinder that can slide radially and are uniformly controlled by a power drive device to achieve synchronous sliding; it can accurately fit piles of different diameters, form stable constraints on the piles from multiple directions, effectively resist external forces such as water flow and waves, ensure the verticality and positional accuracy of pile driving, and improve positioning reliability.

[0015] 2. Each guide roller assembly can slide radially along the supporting cylinder.

[0021] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0022] like Figures 1-4 The diagram shows an efficient offshore piling guidance device that is easy to position. It includes a support cylinder 1 with a piling through hole 2 on the upper end face of the support cylinder 1. Multiple guide roller assemblies are evenly distributed along the circumference inside the support cylinder 1. Each guide roller assembly can slide radially along the support cylinder 1. A power drive device is also provided on the support cylinder 1, which can drive all the guide roller assemblies to slide inward or outward simultaneously.

[0023] According to the above structure, multiple guide roller assemblies evenly distributed along the circumference inside the supporting cylinder 1 can slide radially, and are uniformly controlled by a power drive device to achieve synchronous sliding. This allows for precise fitting of piles of different diameters, providing stable constraints on the piles from multiple directions, effectively resisting external forces such as water flow and waves, ensuring the verticality and positional accuracy of the pile driving, and improving positioning reliability.

[0024] Each guide roller assembly can slide radially along the supporting cylinder 1. Combined with the synchronous drive function of the power drive device, this allows the device to quickly adapt to piles of different diameters. When changing pile specifications, there is no need for complex disassembly or component replacement; all guide roller assemblies can slide simultaneously inwards or outwards via the power drive device, completing the adjustment in a short time. This significantly reduces the time spent changing piles, improves construction efficiency, and avoids delays in the construction schedule.

[0025] Moreover, each guide roller assembly can be adjusted simultaneously under the action of the power drive device, thereby greatly improving the adjustment accuracy.

[0026] Furthermore, the guide roller assembly includes a sliding frame 21, a track 22 is provided on the end face of the supporting cylinder 1, the sliding frame 21 slides on the track 22, and guide rollers 23 are provided on the sliding frame 21, with all the guide rollers 23 surrounding to form a guide channel 24.

[0027] Specifically, the guide roller assembly consists of a sliding frame 21, a track 22, and a guide roller (23). The track 22 is fixedly installed on its end face, and the cross-section of the track is T-shaped or dovetail-shaped to ensure stable sliding of the sliding frame 21. The sliding frame 21 is provided with a slider that matches the track 22, which can slide smoothly on the track 22. The guide roller 23 is installed on the sliding frame 21 through a bearing and can rotate freely. All the guide rollers 23 surround to form a guide channel 24, in which the pile falls. The rotation of the guide roller 23 reduces the friction with the pile.

[0028] The guide roller 23 is rotatably mounted on the sliding frame 21 via bearings and can rotate flexibly. The middle part of the guide roller 23 is designed with an arc-shaped concave structure. The concave arc matches the outer arc of common pile bodies, so that the guide roller 23 can better fit the surface of the pile body.

[0029] See Figures 1-4 As shown, the power drive device includes a rotating ring 41 rotatably mounted on the end face of the supporting cylinder 1. A gear ring 42 is provided on the outer wall of the rotating ring 41. A motor 43 is provided on the outside of the supporting cylinder 1. A gear 44 that can mesh with the gear ring 42 is provided on the output shaft of the motor 43. A guide rod 45 is provided on each of the sliding frames 21. A straight slide groove 46 extending radially along the end face of the supporting cylinder 1 is provided. An oblique slide groove 47 is provided on the rotating ring 41. The guide rod 45 passes through the straight slide groove 46 and the oblique slide groove 47 respectively.

[0030] Specifically, the power drive device includes a rotating ring 41, a gear ring 42, a motor 43, a gear 44, a guide rod 45, a straight slide groove 46, and an inclined slide groove 47. The motor 43 is a servo motor, which is fixedly installed on the outside of the supporting cylinder 1. The gear 44 is installed on the output shaft of the motor 43, and the gear 44 meshes with the gear ring 42. Each sliding frame 21 has a guide rod 45 vertically fixed on it. A straight slide groove 46 is machined radially on the end face of the supporting cylinder 1, and an inclined slide groove 47 is machined on the rotating ring 41. The guide rod 45 passes through both the straight slide groove 46 and the inclined slide groove 47 and can slide within the slide groove. When the motor 43 drives the gear 44 to rotate, it drives the gear ring 42 and the rotating ring 41 to rotate. Through the cooperation of the inclined slide groove 47 and the guide rod 45, and the guiding effect of the straight slide groove 46 on the guide rod 45, the sliding frame 21 slides radially along the track 22.

[0031] A circular guide rail 51 is provided on the end face of the supporting cylinder 1, and a circular slider 52 that slides within the circular guide rail 51 is provided at the lower end of the rotating ring 41. The cooperation between the circular guide rail 51 and the circular slider 52 provides good guidance and support for the rotation of the rotating ring 41, reducing the shaking and offset of the rotating ring 41 during rotation, and ensuring the stability and smoothness of rotation. This not only extends the service life of the rotating ring 41 and related components, but also ensures the accuracy of the power drive device transmission, thereby improving the working reliability of the entire guiding device.

[0032] In this invention, four sets of guide roller assemblies are evenly distributed along the circumference; each set of guide roller assemblies has the same structure and size, and is symmetrically distributed inside the supporting cylinder 1, together forming the guide channel 24.

[0033] This symmetrically distributed structure further enhances the stability and accuracy of the guidance, especially in resisting water flow and wave impact from different directions, and can more effectively maintain the verticality of the pile.

[0034] A conical guide bucket 71 is provided at the upper edge of the piling through hole 2. The conical guide bucket 71 is welded from steel plates. Its lower end is connected to the edge of the piling through hole 2, and its upper end is flared. The opening diameter is larger than the diameter of the piling through hole 2, and it gradually narrows from the upper end to the lower end to form a smooth conical transition surface.

[0035] A mounting base plate 81 is provided on one side of the supporting cylinder 1, and a plurality of mounting through holes 82 are provided on the mounting base plate 81.

[0036] Specifically, a mounting base plate 81 is welded and fixed on one side of the supporting cylinder 1. The mounting base plate 81 is made of a thick steel plate to ensure the connection strength. Several mounting through holes 82 are machined on the mounting base plate 81. The diameter and position of these through holes are determined according to the connection structure of the piling platform or other installation foundation, and are used to fix the entire guide device in the designated position by bolts and other connecting parts.
