DETAILED DESCRIPTION

[0022] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. This embodiment does not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] A double protection hydraulic anchor device for ultra-large ships, such as Figure 1 and Figure 2 As shown, it comprises a chain stopper 1, a hydraulic anchor pulling device and an anchor chain barrel 14. The chain stopper 1 supports an anchor chain 2 in the middle and upper part. One end of the anchor chain 2 extends downward from the head end of the chain stopper 1 into the anchor chain barrel 14. The hydraulic anchor pulling device comprises a hydraulic anchor wire rope 7, which passes through the anchor chain 2 and one end of which is connected to a hydraulic drive assembly.

[0024] In this embodiment, the hydraulic drive assembly includes a hydraulic cylinder 3, which is hinged to the chain stopper 1; specifically, a hydraulic cylinder support seat 4 is fixedly connected to the middle of one side of the chain stopper 1, and the hydraulic cylinder 3 is hingedly installed in the hydraulic cylinder support seat 4; the upper end of the hydraulic cylinder support seat 4 can be installed with a sealing plate 4a by bolts, and a hydraulic cylinder connecting device 3a is installed on the inner side of the sealing plate 4a, and the hydraulic cylinder connecting device 3a is hinged to the middle of the hydraulic cylinder 3, and it can also give the hydraulic cylinder 3 more degrees of freedom through the hydraulic cylinder connecting device 3a.

[0025] like Figure 2 and Figure 3As shown in the figure, on both sides of the head of the chain stopper 1, a first lashing post 1a and a second lashing post 1b are respectively connected; the end of the output end of the hydraulic cylinder 3 is connected with a first shackle 5, and is connected to the hydraulic anchor cable 7 through the first shackle 5. The hydraulic anchor cable 7 first passes through the first lashing post 1a, then passes through the anchor chain 2, and finally is sleeved on the second lashing post 1b.

[0026] As Figure 2 shown in the figure, the output end of the hydraulic cylinder 3 is also hinged to the hydraulic anchor locking device 6 to lock this end; the hydraulic anchor locking device 6 includes a hydraulic anchor support seat 6g. The lower end of the hydraulic anchor support seat 6g is welded to the side of the chain stopper 1, and one side of the upper end is hinged to the locking plate 6c through a second pin 6d. One end of the locking plate 6c is hinged to the hydraulic cylinder 3 through a first pin 6b, and the other end is provided with a card slot.

[0027] On the side of the hydraulic anchor support seat 6g away from the locking plate 6c at the upper end, a third pin 6f is connected. A stud is connected in the third pin 6f. The stud is rotationally connected to the third pin 6f around its own axis. The outer end of the stud is connected with a first handwheel 6a. A locking column 6e is threadedly connected to the stud. There is a thread in the middle of the locking column 6e, and it moves up and down on the stud of the first handwheel 6a through the thread (the locking column 6e only moves up and down and does not rotate through manual control or connection to a guiding device); the card slot opened at the end of the locking plate 6c is adapted to the locking column 6e. The locking plate 6c can be set as two symmetrical ones to facilitate both ends of the locking column 6e to be locked into the card slot.

[0028] In this embodiment, the third pin 6f is rotationally connected to the hydraulic anchor support seat 6g, driving the stud to rotate around the third pin 6f to realize the left and right swing of the first handwheel 6a. After the anchor chain 2 is tightened, the first handwheel 6a is swung to the corresponding position, and the first handwheel 6a is rotated so that the locking column 6e is stuck in the card slot at one end of the locking plate 6c. Rotating the first handwheel 6a can further tighten the anchor chain 2 and release the force on the hydraulic cylinder 3 so that it is not under long-term stress.

[0029] As Figure 4 shown in the figure, a manual anchor device 8 is fixedly connected to the deck on one side of the chain stopper 1. A second shackle 12 is installed at one end of the manual anchor device 8. The second shackle 12 is connected to the manual anchor cable 13. The end of the manual anchor cable 13 away from the manual anchor device 8 first passes through the first guide post 9, then passes through the anchor chain 2, then passes through the second guide post 10, and finally is sleeved on the third lashing post 11.

[0030] As Figure 5As shown, the manual anchor stopper device 8 includes a manual anchor stopper support base 8e, which is welded to the deck. A handwheel support base 8b and an eye plate 8m are fixedly connected to the manual anchor stopper support base 8e. A second handwheel 8a is rotatably connected in the handwheel support base 8b. The second handwheel 8a passes downward through the handwheel support base 8b and is connected to a first helical gear 8c. A meshing second helical gear 8d is provided on one side of the first helical gear 8c. The second helical gear 8d is connected to a threaded rod 8f, and the threaded rod 8f is rotatably connected to the manual anchor stopper support base 8e, realizing the rotation of the threaded rod 8f driven by the second handwheel 8a; the second handwheel 8a uses helical gears to raise the height of the handwheel and place it horizontally, which is more ergonomic and convenient for multiple people to operate;

[0031] A turnbuckle 8g is threadedly connected to the threaded rod 8f. The turnbuckle 8g is slidably connected to the manual anchor stopper support base 8e (a limiting rod 8n is welded inside the eye plate 8m, and a limiting groove for the insertion of the limiting rod 8n is provided on the outer circumference of the turnbuckle 8g to limit its linear sliding). One end of the turnbuckle 8g is connected to a second shackle 12, and is connected to the manual anchor wire rope 13 through the second shackle 12.

[0032] The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
