Description

Technical Field

[0001] The utility model relates to a lock technology, in particular to a lock for hoisting and turning over a super-large offshore pile foundation. Background Art

[0002] Before installing the offshore wind turbine tower, it is necessary to drive piles into the seabed to ensure the stability of the wind turbine tower. The flipping operation of marine piles is to flip the piles placed on the engineering ship from a horizontal state to a vertical state by a crane or a flipping device. At present, for some small diameter and light weight piles, the crane can flip them directly from the ship. But for some large diameter and heavy piles, a flipping device must be used to assist the crane in flipping the piles. When the crane flips, one end of the pile needs to be fixed. If a hook structure is used, it is obviously impossible to connect to the pile. When a clamping mechanism is used, it is easy for the huge pile to break away from the clamping mechanism, which may lead to an accident. Therefore, a lock that is safe, firm and easy to unhook is needed. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figures 1 to 4 As shown, the offshore super-large pile lifting and flipping hoisting lock of the utility model includes a first fixed body 1, a second fixed body 2, a connecting body 3 and a locking assembly 4. The connecting body 3 connects the first fixed body 1 and the second fixed body 2. The locking assembly 4 is located in the middle of the second fixed body 2, and an accommodating area 6 for accommodating the pile 5 is formed between the first fixed body 1 and the second fixed body 2.

[0023] A cylinder 7 is provided at one end of the first fixed body 1, and a movable hole 9 and symmetrically arranged locking holes 10 are provided in the middle of the first fixed body 1, and the locking holes 10 are located at both ends of the movable hole 9. The movable hole 9 is used for the cylinder rod 8 to be placed therein, and the locking hole 10 is used for the locking member 11 to extend therein, so that two locking members 11 and one cylinder rod 8 are formed to lift the foundation pile 5, thereby ensuring the stability of the foundation pile 5 and avoiding the risk of the foundation pile 5 falling out of the lock. At the same time, the one cylinder rod 8 and two locking members 11 play the effect of sharing the weight.

[0024] The second fixed body 2 is arranged on the opposite side of the first fixed body 1, and the second fixed body 2 is composed of symmetrically arranged mounting bodies 12, and a locking assembly 4 is arranged between the symmetrically arranged mounting bodies 12. The locking assembly 4 is provided with a pusher 13 and a driving member 14, a flip member 15 and a locking member 11 arranged on both sides of the pusher 13, the driving member 14, the flip member 15 and the locking member 11 are respectively arranged at two locations, and the driving member 14 and the flip member 15 are both symmetrically rotated.

[0025] The lower end of the pusher 13 is hingedly connected to one end of the driving member 14, and the other end of the driving member 14 is hingedly connected to one end of the flip member 15. The middle of the flip member 15 is hinged in the mounting body 12 through a first hinge shaft 16, and the mounting body 12 is provided with a hinge hole 17 for accommodating the first hinge shaft 16.

[0026] The flip member 15 is connected to the locking member 11 through a hinge 18, the other end of the flip member 15 is hinged to one end of the hinge 18, and the other end of the hinge 18 is hinged to one end of the locking member 11. The flip member 15 is composed of a hinged portion 19, a first flip portion 20, and a second flip portion 21. The hinged portion 19 is hinged to the mounting body 12 through a first hinge shaft 16, the first flip portion 20 is hinged to the driving member 14, and the second flip portion 21 is connected to the hinge 18. The distance between the first flip portion 20 and the hinge 19 is smaller than the distance between the second flip portion 21 and the hinge 19.

[0027] There is an angle of 90° between the first flip portion 20 and the second flip portion 21. If the locking member 11 needs to be pushed for a longer distance in practice, the length of the second flip portion 21 can be lengthened, so that the flip member 15 can push the locking member 11 for a longer distance, so as to facilitate passing through the thicker foundation pile 5.

[0028] The cylinder 7 drives the pusher 13, so that the driving member 14 pushes the rod flip member 15 to push the hinge 18, and the hinge 18 pushes the locking member 11 into the locking hole 10. The cylinder 7 drives the cylinder rod 8, so that the cylinder rod 8 drives the pusher 13, the pusher 30 compresses the spring 22, and the pusher 13 pushes the driving member 14. Since the driving member 14 is arranged in rotational symmetry, the lower ends of the two driving members 14 push toward both ends respectively, pushing the first flip part 20 on the flip member 15, so that the flip member 15 rotates on the first hinge shaft 16, and pushes the hinge 18 through the second flip part 21, and then the hinge 18 pushes the locking member 11 into the connecting hole 23, and then enters the locking hole 10 in the first fixed body 1.

[0029] The mounting body 12 is provided with an active chamber 24 and a first sliding groove 25 and a second sliding groove 26 communicating with the active chamber 24. The second sliding groove 26 is located at both ends of the first sliding groove 25. The first sliding groove 25 and the second sliding groove 26 are communicated with the active chamber 24. The pusher 13 is arranged in the first sliding groove 25, and the locking member 11 is arranged in the second sliding groove 26. The first sliding groove 25 is provided with a stepped portion 27 and a blocking portion 28, and an arc-shaped hole 29 is arranged in the middle of the blocking portion 28.

[0030] The step portion 27 is used to limit the position of the pusher 13 , thereby preventing the spring 22 from pushing the pusher 30 out of the first sliding slot 25 .

[0031] The pushing member 13 is composed of a pushing portion 30, a rod body 31 and a sliding portion 32. The rod body 31 is located in the arc hole 29. The diameter of the pushing portion 30 is larger than the diameter of the rod body 31. A spring 22 is sleeved on the rod body 31. The upper end of the spring 22 contacts the pushing portion 30, and the lower end is placed on the blocking portion 28.

[0032] Three connecting holes 23 are provided on the foundation pile 5 for the cylinder rod 8 and the locking member 11 to pass through and then enter the locking hole 10, so as to realize the locking of the foundation pile 5 by the locking member 11 assembly, so as to facilitate the crane to lift the connecting body 3, and then lift the first fixed body 1 and the second fixed body 2 through the connecting body 3, so as to realize the flipping of the foundation pile 5. In addition, since the accommodating area 6 is penetrated at both ends, the foundation pile 5 that falls on the ground can be conveniently locked.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
