[0022] In order to elaborate on the technical scheme adopted by the present invention to achieve the predetermined technical purpose, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments, and the technical means or technical features in the embodiments of the present invention can be replaced without paying creative work. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0023] like Figure 1 As shown, a ladder installation auxiliary docking device for an offshore wind power single pile foundation of the present invention comprises a ladder structure clamp 1, a clamp support 2, a clamp reset cylinder 3, a clamp rotating support 4, a telescopic arm mechanism 5 and a lateral movement mechanism 6. The ladder structure clamp 1 is hinged on the upper side of the clamp support 2, one end of the clamp reset cylinder 3 is hinged to the ladder structure clamp 1, and the other end of the clamp reset cylinder 3 is hinged to the clamp support 2. The clamp support 2 is rotatably arranged on the clamp rotating support 4 and is driven to rotate in the clamp rotating support 4 by a rotation driving mechanism. The clamp rotating support 4 is arranged at one end of the telescopic arm mechanism 5, and the other end of the telescopic arm mechanism 5 is arranged on the lateral movement mechanism 6 and is driven by the lateral movement mechanism 6 to move back and forth on a horizontal plane perpendicular to the length direction of the telescopic arm mechanism 5.

[0024] A vertical positioning mechanism is provided between the ladder structure fixture 1 and the fixture support 2. The vertical positioning mechanism includes a positioning ear seat 7 and a positioning pin 8. The positioning ear seat 7 is fixed to the lower side of one end of the ladder structure fixture 1. The side of the fixture support 2 is provided with an ear seat cavity matching the positioning ear seat 7. The positioning ear seat 7 and the ear seat cavity are provided with corresponding pin holes. The positioning pin 8 is provided on the side of the ear seat cavity and is driven by a positioning oil cylinder to extend and retract in the pin hole. When the ladder structure fixture 1 is rotated to a vertical direction along the hinge axis, the positioning ear seat 7 is embedded in the ear seat cavity and the positioning oil cylinder drives the positioning pin 8 to be inserted into the positioning ear seat 7 and the pin hole of the ear seat cavity to position the ladder structure fixture 1 in a vertical position. The vertical position of the ladder structure fixture 1 is its working state position, which is positioned by the positioning ear seat 7 and the positioning pin 8 to ensure the stability of its working state.

[0025] like Figure 2 and Figure 3 As shown, the ladder structure clamp 1 includes a base plate 9, an external frame 10, a first clamp 11, a second clamp 12, a third clamp 13, a first clamp driving cylinder 14 and a third clamp driving cylinder 15. The first clamp 11, the second clamp 12 and the third clamp 13 are slidably arranged on the base plate 9 in sequence and can slide back and forth along the length direction of the base plate 9. The external frame 10 is fixed on the base plate 9, the first clamp driving cylinder 14 and the third clamp driving cylinder 15 are respectively fixed on the external frame 10, the first clamp 11 is connected to the first clamp driving cylinder 14 and is driven by the first clamp driving cylinder 14, and the third clamp 13 is connected to the third clamp driving cylinder 15 and is driven by the third clamp driving cylinder 15.

[0026] A first electromagnet 16 is provided on the side of the first clamp 11 facing the second clamp 12, a second electromagnet 17 is provided on the side of the third clamp 13 facing the second clamp 12, a third electromagnet 18 is provided on the side of the external frame 10 facing the second clamp 12, and when the third electromagnet 18 attracts the second clamp 12, the second clamp 12 is located in the middle position of the base plate 9.

[0027] When working, the first clamp 11, the second clamp 12 and the third clamp 13 clamp the ladder structure at the same time, and the first clamp 11 is located at the top of the base plate 9, the second clamp 12 is located in the middle of the base plate 9 and is fixed by the third electromagnet 18, and the third clamp 13 is located at the bottom of the base plate 9. When the ladder structure needs to be moved upward, the first clamp 11 is released, and the second clamp 12 and the third clamp 13 remain clamped. At this time, the third clamp driving cylinder 15 drives the third clamp 13 to move upward. Since the second clamp 12 and the third clamp 13 are both clamped on the ladder structure, the second clamp 12 moves upward synchronously with the third clamp 13. When the upper end of the second clamp 12 contacts the lower end of the first clamp 11, the first electromagnet 16 works to adsorb the second clamp 12 on the lower side of the first clamp 11. At this time, the first clamp 11 clamps the ladder structure, and the second clamp 12 remains clamped. The third clamp 13 is released and moves downward under the drive of the third clamp driving cylinder 15 until the lower end of the base plate 9, and then the third clamp 13 clamps the ladder structure. At this time, the second clamp 12 releases the ladder structure, the first electromagnet 16 stops working, and the third electromagnet 18 starts working. The second clamp 12 slides downward under its own weight to the third electromagnet 18 and is adsorbed and fixed. At this time, the second clamp 12 clamps the ladder structure to restore the initial state, completing an ascending cycle. The ladder structure can move downward in the opposite way to the up and down movement, so it will not be repeated.

[0028] The first clamp 11, the second clamp 12 and the third clamp 13 respectively include a clamp bracket 19, a clamp base plate 20, a first clamp 21, a first clamp arm 22, a first clamp driving cylinder 23, a second clamp 24, a second clamp arm 25 and a second clamp driving cylinder 26. One side of the clamp bracket 19 is provided with a slide groove structure matching the base plate 9. One side of the clamp bracket 19 is sleeved on the outer side of the base plate 9 through the slide groove structure and can slide along the length direction of the base plate 9. One side of the clamp base plate 20 is connected to the other side of the clamp bracket 19. Half grooves matching the ladder structure are set at both ends of the other side of the clamp base plate 20. The inner sides of the first clamp 21 and the second clamp 24 are also provided with half grooves matching the ladder structure. The first clamping jaw 21 and the second clamping jaw 24 are respectively arranged opposite to the half grooves on both sides of the clamp base plate 20, the first clamping jaw 21 is hinged at one end of the clamp base plate 20, one end of the first clamping jaw arm 22 is fixedly connected to the first clamping jaw 21, the other end of the first clamping jaw arm 22 is hinged to one end of the first clamping jaw driving cylinder 23, the other end of the first clamping jaw driving cylinder 23 is hinged to the end surface of one end of the clamp base plate 20, the second clamping jaw 24 is hinged to the other end of the clamp base plate 20, one end of the second clamping jaw arm 25 is fixedly connected to the second clamping jaw 24, the other end of the second clamping jaw arm 25 is hinged to one end of the second clamping jaw driving cylinder 26, and the other end of the second clamping jaw driving cylinder 26 is hinged to the end surface of the other end of the clamp base plate 20. The first clamp driving cylinder 23 drives the first clamp arm 22, and the first clamp arm 22 drives the first clamp 21 to rotate and open and close along the hinge axis at one end of the clamp base plate 20. Similarly, the second clamp 24 is driven to open and close by the second clamp driving cylinder 26 to complete the clamping and fixing of the ladder structure.

[0029] A horizontal adaptive adjustment mechanism is arranged between the clamp base plate 20 and the clamp bracket 19, and the horizontal adaptive adjustment mechanism includes a first slide rod 27, a first spring 28, a second slide rod 29 and a second spring 30. A protrusion 31 protruding from the surface of the other side of the clamp bracket 19 is arranged in the middle of the other side of the clamp bracket 19. A slide groove matching the protrusion 31 is opened on one side of the clamp base plate 20, and the length of the slide groove is greater than the length of the protrusion 31. The first slide rod 27 and the second slide rod 29 are arranged on both sides of the protrusion 31 along the length direction of the protrusion 31. The slide groove A first slot 32 is formed at one end of the slide along the length direction of the protrusion 31, and a second slot 33 is formed at the other end of the slide along the length direction of the protrusion 31. One end of the first slide rod 27 is fixed to one side of the protrusion 31, and the other end of the first slide rod 27 is slidably arranged in the first slot 32. The first spring 28 is sleeved on the outside of the first slide rod 27. One end of the second slide rod 29 is fixed to the other side of the protrusion 31, and the other end of the second slide rod 29 is slidably arranged in the second slot 33. The second spring 30 is sleeved on the outside of the second slide rod 29. When the ladder structure is docked and installed, since the design accuracy of the jib crane and the auxiliary positioning docking device itself is not very high, it is inevitable that there is a certain misalignment between the pin on the ladder structure and the sleeve on the pile body during positioning docking. Through the structural design of the horizontal adaptive adjustment mechanism, when horizontal misalignment occurs, when the pin is inserted into the sleeve, the clamp base plate 20 will automatically slide horizontally on the clamp bracket 19 to adjust the position, so as to avoid the auxiliary positioning docking device from being damaged.

[0030] like Figure 4 As shown, the rotary drive mechanism includes a rotating drum 34, a rotating drum bearing 35, a gear ring 36, a driving gear 37 and a gear motor 38.

The gear ring 36 is fixed at the lower end of the rotating drum 34 and meshes with the driving gear 37. The driving gear 37 is connected to the gear motor 38 and driven by the gear motor 38. The gear motor 38 drives the driving gear 37 to rotate, and the driving gear 37 drives the gear ring 36 to rotate, thereby driving the clamp support 2 to rotate in the clamp rotating support 4, so as to adjust the working angle of the ladder structure clamp 1.
