Description

Technical Field

[0001] This utility model relates to the field of piling vessels, and more specifically, to a positioning pile structure for a rotary piling vessel. Background Technology

[0002] A rotary piling vessel is a special type of engineering vessel mainly used for piling operations in aquatic environments. Its key feature is its rotating platform, on which the pile frame and piling equipment are mounted. The platform's rotation allows for flexible changes in the piling direction without the need for frequent platform repositioning. While the pile is pre-installed vertically on the piling equipment, the suspended pile is only restrained at its top, resulting in insufficient stability. This is particularly problematic in complex river construction, where pile tilting frequently occurs. Utility Model Content

A laser calibration mechanism is provided on the front side of the upper surface of the rotating platform.

[0008] Furthermore, the extension rod is horizontally forward, and a rotating bushing is rotatably mounted on the surface of the extension rod. The center of the rotating bushing surface has a concave surface that matches the curved surface of the pile.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figures 1-3 As shown, a positioning pile structure for a rotary piling vessel includes a rotary platform 1, which is located at the front of the vessel. A notch 12 is formed at the center of the front side of the rotary platform 1. During installation, the rotation of the rotary platform 1 allows the notch 12 to face the pile stacking area. When one end of the pile is lifted, the other end can penetrate the notch 12 and be submerged in water, increasing installation space. A support platform 11 is provided on the rear side of the upper surface of the rotary platform 1, higher than the upper surface of the rotary platform 1. A pile frame 13 is vertically fixed to the front end of the upper surface of the support platform 11. A pile driver 14 is vertically slidably mounted on the front surface of the pile frame 13. During piling, one end of the pile is installed at the bottom of the pile driver 14 and kept vertical. The position is then adjusted using the rotary platform 1. Symmetrical diagonal supports 16 are provided on the rear side of the pile frame 13 to improve its strength. A horizontal mounting groove 15 is formed on the front surface of the support platform 11. A positioning mechanism 4 is provided inside the mounting groove 15. The positioning mechanism 4 includes a bidirectional screw 41 horizontally rotatably mounted inside the mounting groove 15. Two movable blocks 46 are symmetrically slidably installed inside the mounting groove 15. Both movable blocks 46 are screwed onto the bidirectional screw 41, and the two movable blocks 46 are screwed onto different threaded surfaces, so that the rotation of the bidirectional screw 41 drives the two movable blocks 46 to move synchronously, synchronously approaching or synchronously moving away. An extension rod 47 is provided at the front end of the movable block 46. The extension rod 47 extends beyond the front surface of the mounting groove 15. The two extension rods 47 are respectively placed on both sides of the notch groove 12. A laser calibration mechanism 5 is provided on the front side of the upper surface of the rotating platform 1.

[0023] Please refer to Figure 2 As shown, the extension rod 47 is horizontally forward, and a rotating bushing 48 is rotatably installed on the surface of the extension rod 47. A concave surface 49 adapted to the curved surface of the pile body is opened at the center of the surface of the rotating bushing 48. The cylindrical pile body is limited by the concave surface 49. The rotating bushing 48 can rotate during the downward movement of the pile body to ensure the smoothness of pile driving.

[0024] Please refer to Figure 3 As shown, a gear A42 is provided at one end of the bidirectional screw 41. The gear A42 extends beyond the upper surface of the support platform 11. A vertical plate 43 is provided on one side of the surface of the support platform 11. A gear B45 is rotatably mounted on one side of the surface of the vertical plate 43. The gear B45 is positioned above the gear A42 and meshes with the gear A42. The gear A42 is larger than the gear B45 to improve the torque during control. A control wheel 44 is coaxially mounted on one side of the gear B45. The control wheel 44 and the gear B45 are respectively positioned on both sides of the vertical plate 43 for easy operation.

[0025] Please refer to Figure 1 and Figure 4 As shown, the laser calibration mechanism 5 is placed on one side of the notch 12. The laser calibration mechanism 5 includes a rotating rod 51 that rotates on the upper surface of the rotating platform 1. A mounting plate 52 is provided at the end of the rotating rod 51. The mounting plate 52 is placed at the center of the notch 12 so that the laser calibrator 53 is on the same straight line as the pile body, which facilitates calibration. The laser calibrator 53 is rotatably mounted on the upper surface of the mounting plate 52. The laser calibrator 53 is a bidirectional laser, with one side facing the reference object and the other side facing the pile body.

[0026] A fixing block 54 is provided on one side of the notch 12. The fixing block 54 is located in front of the rotating rod 51. The fixing block 54 can make the rotating rod 51 perpendicular to the side of the notch 12, so as to ensure that the laser calibrator 53 is placed in the center of the notch 12. A rear extension plate 55 is provided on the end of the rotating rod 51 away from the mounting plate 52.

[0027] The rotating platform 1 has two positioning holes 56 on its surface, and a fixing pin 57 is inserted into the surface of the rear extension plate 55. The end of the fixing pin 57 is adapted to the internal size of the positioning hole 56 to fix the rotating rod 51 and ensure the stability of its position after extension and retraction.

[0028] Working principle: First, the pile body is hoisted onto the lower surface of the pile driver 14 so that the pile can be driven by the pile driver 14. The pile body moves down through the notch 12. During the downward movement of the pile body, the rotating control wheel 44 can be rotated to drive the gear B45 to rotate. The meshing of gear B45 and gear A42 drives the bidirectional screw 41 to rotate. Then, the distance between the two moving blocks 46 is adjusted. When the pile body is installed, the two moving blocks 46 are separated from each other. When the pile body is installed in place, the two moving blocks 46 are brought closer to each other so that the two rotating bushings 48 contact the pile body. The concave surface 49 positions the pile body, and the rotating bushings 48 ensure the smoothness of the downward movement of the pile body.

[0029] During pile driving, the rotating rod 51 can be rotated to place the mounting plate 52 in the center of the notch 12. The laser calibrator 53 can be used to accurately position the mounting plate 52 with the positioning point on the bank or the previous pile. The fixing block 54 on the front side can ensure that the rotating rod 51 is perpendicular to the side of the notch 12, which makes it easy to control the angle of the laser calibrator 53. The fixing pin 57 at the rear can keep the position of the rotating rod 51 stable. Conversely, when installing the pile, it can be rotated 90 degrees counterclockwise so that the laser calibrator 53 does not coincide with the notch 12. The fixing pin 57 cooperates with the positioning hole 56 on the front side to prevent the pile from hitting the equipment.

[0030] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
