[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1A structural schematic diagram of a preferred embodiment of the pile head positioning device provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the positioning assembly shown; Figure 3 for Figure 1 A schematic structural diagram of the first fixing plate and the limiting rod is shown; Figure 4 for Figure 1 A pile head positioning device comprises a positioning cylinder 1, a mounting plate 2 is arranged on the top of the positioning cylinder 1, and a pile driving head 3 is arranged above the mounting plate 2;

[0024] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, the positioning assembly 4 is arranged on the top of the assembly plate 2, and the positioning assembly 4 includes a guide rail 41, a slider 42, a scale 43, a connecting block 44 and a reference block 45.

[0025] An arc block 6 is fixedly connected to one side of the connecting block 44 , a first spring 7 is welded to one side of the connecting block 44 , and a second threaded rod 8 is provided on one side of the connecting block 44 .

[0026] The outer side of the second threaded rod 8 is threadedly connected to a support plate 9 , one end of the second threaded rod 8 is fixedly connected to a knob 10 , and the bottom of the support plate 9 is fixedly connected to the top of the assembly plate 2 .

[0027] A first fixing plate 11 is fixedly connected to the inner wall of the positioning tube 1 , and a limiting rod 12 is fixedly connected to the bottom of the first fixing plate 11 .

[0028] One end of the limiting rod 12 is fixedly connected to a second fixing plate 13 , and one side of the second fixing plate 13 is fixedly connected to the inner wall of the positioning tube 1 .

[0029] A second spring 14 is welded to the top of the second fixing plate 13 , a support frame 15 is welded to one end of the second spring 14 , and one end of the support frame 15 is slidably connected to the outer side of the limiting rod 12 .

[0030] It should be noted that: four sets of guide rails 41, sliders 42, scales 43 and arc blocks 6 are respectively arranged on the top of the assembly plate 2. The other end of the first spring 7 is welded to one side of the support plate 9 to support and stabilize the movement of the connecting block 44. The reference block 45 is installed on the connecting block 44 and close to one side of the scale 43. It is convenient to use it together for precise positioning. The knob 10 is rotated to make the second threaded rod 8 drive the connecting block 44 to move. At the same time, under the connection of the slider 42, it slides under the limit of the guide rail 41, and with the cooperation of the two first springs 7, the stability of the movement is improved. Under the action of the reference block 45, according to the scale 43, the The positions of the connecting block 44 and the arc block 6 are moved precisely, and the positions of the four arc blocks 6 are adjusted at a uniform distance, which promotes the improvement of the accuracy of the limit and effectively reduces the occurrence of positioning center deviation. The support frame 15 is limited by the first fixed plate 11, the limiting rod 12 and the second fixed plate 13. The maximum diameter of the pile driving head 3 contacts and pushes the support frame 15 to move downward, which plays a supporting role and enhances stability. When the pile driving head 3 is retracted, under the action of the second spring 14, the support frame 15 is driven to reset, and the support frame 15 is limited by the first fixed plate 11, which effectively prevents the support frame 15 from being separated from the limiting rod 12.

[0031] refer to Figure 1 and Figure 4 As shown, the adjustment component 5 is arranged on one side of the assembly plate 2, and the adjustment component 5 includes an adjustment block 51, a first threaded rod 52, a stabilizing rod 53, a worm gear 54 and a worm 55. The adjustment blocks 51 are fixedly connected to both sides of the assembly plate 2, the inner side of the adjustment block 51 is threadedly connected to the first threaded rod 52, the inner side of the adjustment block 51 is slidably connected to the stabilizing rod 53, one end of the first threaded rod 52 is provided with a worm gear 54, and the outer side of the worm gear 54 is meshingly connected to the worm 55.

[0032] One end of the worm 55 is fixedly connected to a connecting rod 16 , one end of the connecting rod 16 is fixedly connected to a motor 17 , and the bottom of the stabilizing rod 53 is fixedly connected to a moving plate 18 .

[0033] The inner side of the moving plate 18 is threadedly connected with a third threaded rod 19 , and one end of the third threaded rod 19 is provided with a fixed claw plate 20 .

[0034] It should be noted that the motor 17 and the worm gear 54 are fixed and supported by the movable plate 18, and a support block is provided at one end of the worm 55 to stabilize and limit it. Under the drive of the motor 17, the connecting rod 16 drives the worm 55 to rotate, and under the meshing action, the worm gear 54 drives the first threaded rod 52 to rotate, so that the adjusting block 51 drives the assembly plate 2 to move. At the same time, the adjusting block 51 on the other side of the assembly plate 2 slides synchronously under the limitation of the stabilizing rod 53, supports and stabilizes the movement of the assembly plate 2, facilitates the adjustment of the height of the assembly plate 2 as needed, and promotes the realization of the positioning effect. By controlling the operation of the third threaded rod 19 on the movable plate 18, the fixed claw plate 20 is inserted into the platform, thereby enhancing the stability of the movable plate 18 and preventing the movable plate 18 from moving during piling.

[0035] The working principle of a pile head positioning device provided by the utility model is as follows:

[0036] When in use, under the action of the moving plate 18, the overall device is promoted to move on the offshore wind power operation platform and move to the bottom of the pile driving head 3. At the same time, the pile driving head 3 is aligned with the center of the assembly plate 2 and the positioning tube 1. By controlling the third threaded rod 19 to drive the fixed claw plate 20 to be inserted into the corresponding hole of the platform, the moving plate 18 is effectively prevented from moving during piling. Under the drive of the motor 17, the connecting rod 16 drives the worm 55 to rotate. Under the meshing action, the worm gear 54 drives the first threaded rod 52 to rotate, thereby causing the adjusting block 51 to drive the assembly plate 2 to move. At the same time, the adjusting block 51 on the other side of the assembly plate 2 slides synchronously under the limit of the stabilizing rod 53, supporting and stabilizing the movement of the assembly plate 2, facilitating the adjustment of the height of the assembly plate 2 as needed, and adjusting the positioning assembly 4 to be raised and lowered according to different piling requirements to enhance the flexibility of use. The knob 10 is rotated in sequence to cause the second threaded rod 8 to drive the connecting block 44 to move. When the pile driving head 3 is retracted, the support frame 15 is driven to reset under the action of the second spring 14, and the support frame 15 is limited by the first fixed plate 11, the limiting rod 12 and the second fixed plate 13, so as to effectively prevent the support frame 15 from being separated from the limiting rod 12, which is more practical and convenient.
