Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power installation, in particular to a translation type pile gripper for offshore wind power generation foundations. Background Art

[0002] Offshore wind power is a clean energy technology that harnesses offshore wind resources to generate electricity. Wind power utilizes wind power to rotate windmill blades, which are then accelerated by a speed increaser, driving the generator to generate electricity. Current windmill technology requires only a gentle breeze of approximately three meters per second to generate electricity.

[0003] A Chinese patent application, CN216102670U, discloses a translatory pile gripper for offshore wind turbine foundations. This patented technology utilizes a chassis assembly, a pile gripper assembly, a lifting assembly, and a translatory assembly to coordinate and secure foundation piles of varying positions and sizes. This technology boasts strong deviation correction capabilities and a wide range of applications. However, when the pile gripper is clamping the pile, slight angular deviations between the pile's intended position and the gripper assembly can occur. This can lead to unstable gripping of the pile by the gripper's linearly movable positioning elements, making it difficult to adjust the pile's position or to monitor the gripper's position.

[0015] 1. This offshore wind power generation foundation translation pile gripper, when the clamping mechanism needs to be tilted, the side thrust cylinder is activated through an external power supply. The output end of the side thrust cylinder drives the hollow block to tilt forward or backward.

[0016] 2. In addition, this offshore wind turbine foundation translation pile gripper uses an external power supply to activate the transverse locking cylinder. When the output end of the transverse locking cylinder contracts, it drives the locking clamp arm to flip outward. Then, the column holding cylinder is activated by the external power supply. The output end of the column holding cylinder contracts, causing the two large clamp arms to flip outward, thereby expanding the entire clamping mechanism. When clamping and positioning the foundation pile, the output end of the column holding cylinder is first extended, driving the two large clamp arms to flip toward each other to clamp the foundation pile. Then, the output end of the transverse locking cylinder is extended, driving the locking clamp arm to flip inward, so that the two large clamp arms and the locking clamp arm form a ring to clamp the foundation pile. This achieves the desired clamping and positioning effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] like Figure 1 As shown, a translational pile gripper for an offshore wind power generation foundation includes a pair of load-bearing brackets 10, a pair of rear brackets 11 are provided on the left side of the load-bearing brackets 10, the load-bearing brackets 10 and the rear brackets 11 on the same side are fixedly connected by a support frame 14, and the middle of the pair of rear brackets 11 are fixedly connected by a pair of positioning blocks 12 arranged up and down, a movable groove 13 is provided in the middle position of the positioning blocks 12, a flip block 21 is hinged on the inner side of the movable groove 13, a hollow block 22 is slidably connected to the right side of the flip block 21, and a clamping mechanism 30 is provided on the right side of the hollow block 22.

[0024] Preferably, the front and rear sides of the flip block 21 are fixedly connected to the main push cylinder 23 through a connecting piece, and the output end of the main push cylinder 23 is fixedly connected to the hollow block 22. When in use, the two main push cylinders 23 are simultaneously activated by an external power supply, and the output ends of the main push cylinders 23 move the hollow block 22 to the left and right, thereby achieving the effect of adjusting the left and right position of the clamping mechanism 30.

[0025] refer to Figure 5 The clamping mechanism 30 includes a fixing frame 301 fixedly connected to the hollow block 22, and the front and rear sides of the fixing frame 301 are rotatably connected to a flip-up large clamping arm 302 through a hinge. The left end of the front large clamping arm 302 is hinged to a flip-up locking clamping arm 303 through a hinge, and the rear end of the locking clamping arm 303 is installed with a locking member 304.

[0026] Specifically, the front and rear sides of the fixed frame 301 are respectively fixedly connected with connecting blocks 305, and the connecting block 305 is hinged to the column cylinder 307 through a hinge, and the output end of the column cylinder 307 is hinged to a driving member 306, and the driving member 306 is fixedly connected to the large clamping arm 302; the front side of the large clamping arm 302 is hinged to a transverse locking cylinder 308 through a hinge, and the output end of the transverse locking cylinder 308 is hinged to the locking clamping arm 303 through a hinge.

[0027] When in use, the transverse locking cylinder 308 is started by an external power supply. When the output end of the transverse locking cylinder 308 contracts, the locking clamping arm 303 is driven to flip over, and then the column cylinder 307 is started by an external power supply. The output end of the column cylinder 307 contracts to make the two large clamping arms 302 flip outward, thereby expanding the entire clamping mechanism 30. When clamping and positioning the foundation pile, first extend the output end of the column cylinder 307 to drive the two large clamping arms 302 to flip toward each other to clamp the foundation pile, and then extend the output end of the transverse locking cylinder 308 to drive the locking clamping arm 303 to flip inward, so that the two large clamping arms 302 and the locking clamping arm 303 form a ring to clamp and position the foundation pile.

[0028] Furthermore, a pair of pushing devices 310 are respectively installed on the inner side of the two large clamping arms 302. The pushing devices 310 are connected by cylinders and support blocks. When facing foundation piles of different widths, the clamping mechanism 30 may find it difficult to clamp the foundation piles. Therefore, the pushing devices 310 can be started at the same time, and a group of cylinders are started at the same time to drive the support blocks to press against the surface of the foundation piles, thereby achieving the effect of positioning foundation piles of different sizes.

[0029] refer to Figure 2-4 , a pair of tilting mechanisms 40 are provided inside the pair of supporting brackets 10, and the tilting mechanism 40 includes a fixed block 401 fixedly connected to the inner side of a pair of supporting brackets 10, and an inclined groove 402 is provided on the inner side of the fixed block 401, and the inclined groove 402 is movably connected to the corresponding hollow block 22, and guide grooves 403 are provided on the upper and lower sides of the inner side of the inclined groove 402, and a sliding groove 405 is provided on the top of the hollow block 22, and the sliding groove 405 is slidably connected to the inner side of the sliding groove 405, and the guide block 404 is slidably connected to the upper and lower guide grooves 403 respectively; a side push cylinder 406 is fixedly installed on the front side of the inner side of the inclined groove 402, and a slider 408 is hinged at the output end of the side push cylinder 406, and a pair of guide rails 407 are fixedly connected to the front side of the hollow block 22, and the guide rails 407 are slidably connected to the slider 408.

[0030] Preferably, the guide groove 403 is designed to be arc-shaped. During use, when the clamping mechanism 30 needs to be tilted, the side push cylinder 406 is activated by an external power supply. The output end of the side push cylinder 406 drives the hollow block 22 to tilt forward or backward. At the same time, the hollow block 22 drives the guide block 404 to move in the same direction, and the guide block 404 slides along the guide groove 403, thereby achieving the effect of tilting the clamping mechanism 30 forward and backward. At the same time, when the clamping mechanism 30 needs to be adjusted left and right, the main push cylinder 23 is activated. The main push cylinder 23 drives the hollow block 22 and the clamping mechanism 30 to move left and right, and at the same time drives the sliding groove 405 to slide along the surface of the guide block 404, thereby achieving the effect of guiding the movement of the clamping mechanism 30. In this way, the distance and angle adjustment effect of the clamping mechanism 30 is achieved, which is convenient for positioning foundation piles at different positions.

[0031] refer to Figure 1 A walking ladder 15 is fixedly connected to the top of the front supporting bracket 10, and the bottom of the walking ladder 15 is fixedly connected to the ground; when in use, the operator can move to the top of the supporting bracket 10 through the walking ladder 15, which can facilitate the observation of the position of the clamping mechanism 30 and the adjustment of the position of the clamping mechanism 30.

[0032] The working principle of the present utility model is as follows: when the clamping mechanism 30 needs to be tilted, the side push cylinder 406 is activated by an external power supply, and the output end of the side push cylinder 406 drives the hollow block 22 to tilt forward or backward, and at the same time, the hollow block 22 drives the guide block 404 to move in the same direction, and the guide block 404 slides along the guide groove 403, thereby achieving the effect of adjusting the front and rear tilt of the clamping mechanism 30. At the same time, when the clamping mechanism 30 needs to be adjusted to the left and right distance, the main push cylinder 23 is activated, and the main push cylinder 23 drives the hollow block 22 and the clamping mechanism 30 to the left and right positions, and at the same time drives the sliding groove 405 to slide along the surface of the guide block 404, thereby achieving the effect of guiding the movement of the clamping mechanism 30. In this way, the distance and angle adjustment effect of the clamping mechanism 30 is achieved, which is convenient for positioning foundation piles at different positions.
