Description

Technical Field

[0001] The present invention relates to the technical field of anchor chain laying stop devices, and particularly relates to a simple stop device for laying large-sized anchor chains. Background Art

[0002] Nowadays, the application of floating wind turbines has become a new trend in the development of offshore wind power. Among them, the construction of anchor chain laying is a key link in the offshore mooring of deep-sea floating wind power. According to the existing anchor chain laying construction technology, whether it is laying alternately by a winch or lifting the anchor chain by a marine crane, when laying, a relatively large self-weight will be generated in the water entry section of this super-large-sized and heavy anchor chain. This gravity has a tendency to drag the remaining anchor chain on the ship to the seabed. Therefore, when changing the laying point, if the constraint of the laying suspension point on the anchor chain is lost, it is very easy to have an accident of the anchor chain slipping, posing a very serious safety hazard. At the same time, in the traditional method, when changing the laying suspension point of the anchor chain, it is usually necessary to manually tie the anchor chain to the mooring bitt with a steel wire rope for fixation.

[0003] However, when manually tying the anchor chain to the mooring bitt with a steel wire rope, it is not only time-consuming, but also there are safety hazards such as personnel working on the ship's side and the sudden breakage of the steel wire rope. In addition, since the mooring system of general floating wind turbines has relatively high requirements for the routing accuracy of anchor chain laying, if the water entry point of the anchor chain during the laying process is not restricted, the out-chain direction of the anchor chain when entering the water is likely to deviate, and it will be very difficult to adjust at that time. Therefore, a simple stop device for laying large-sized anchor chains is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a simple stop device for laying large-sized anchor chains, and solve the following technical problems:

[0005] When manually tying the anchor chain to the mooring bitt with a steel wire rope, it is not only time-consuming, but also there are safety hazards such as personnel working on the ship's side and the sudden breakage of the steel wire rope. In addition, since the mooring system of general floating wind turbines has relatively high requirements for the routing accuracy of anchor chain laying, if the water entry point of the anchor chain during the laying process is not restricted, the out-chain direction of the anchor chain when entering the water is likely to deviate, and it will be very difficult to adjust at that time.

[0020] (2) In the present invention, through the auxiliary limiting mechanism, a further stopping operation on the anchor chain body is realized when the stop mechanism stops the anchor chain body, making the position of the anchor chain body more stable when changing the suspension point, further avoiding the situation of the anchor chain body slipping during the laying pause and when changing the laying point, and further improving the effect of the stopping operation on the anchor chain body.

[0021] (3) In the present invention, through the mutual cooperation of the provided driving mechanism and the adjusting mechanism, the stop rod and the stop plate can be moved simultaneously by one propulsion device, thereby achieving the purpose of simultaneously stopping the anchor chain body, without the need for separate operations, improving the efficiency of the stopping operation on the anchor chain body to a certain extent, and further restricting the water entry point of the anchor chain body during the laying process.

[0022] (4) In the present invention, the propulsion device and the stop plate are hinged by a pin method, which is convenient for the installation and removal of the stop plate, and is beneficial for replacing the specification of the stop plate according to different specifications of thick and heavy anchor chain bodies, further expanding the application range of the stop mechanism.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0039] Please refer to Figure 1-8As shown in the figure, the present invention is a simple stop device for laying large - specification anchor chains, including a ship deck 1. An installation platform 2 and a placement platform 3 are arranged on the ship deck 1. A stop mechanism 4 and a limit tooling 5 are arranged on the installation platform 2. The limit tooling 5 is used to limit the out - chain direction of the anchor chain. Both the placement platform 3 and the limit tooling 5 are provided in two. The placement platform 3 plays an auxiliary supporting role when the stop plate 43 is in the stopping state. An anchor chain body 7 is placed between the two limit toolings 5, and an auxiliary limit mechanism 6 is arranged on the two limit toolings 5;

[0040] The stop mechanism 4 includes a mounting seat 41. The mounting seat 41 is fixedly installed on the installation platform 2. The propulsion device 42 is installed through the provided mounting seat 41. A propulsion device 42 is arranged on the mounting seat 41. The propulsion device 42 is used to push the stop plate 43. The pushing end of the propulsion device 42 is installed with a stop plate 43. The stop plate 43 passes through the center of the corresponding chain link to complete the stopping operation of the stop plate 43 on the anchor chain. One end of the stop plate 43 is provided with a slope 44. The slope 44 plays a transitional role during the stopping process of the stop plate 43. At the same time, the shear resistance and impact resistance of the stop plate 43 are improved through the slope 44, ensuring that the stop plate 43 can pass through the center of the anchor chain link on the anchor chain body 7 to stop the anchor chain body 7. The other end of the stop plate 43 is provided with a pin hole 45. The stop plate 43 can be pin - hinged to the propulsion device 42 through the provided pin hole 45. The stop plate 43 is hinged to the driving end of the propulsion device 42 through the pin hole 45 and a pin. The hinged method between the stop plate 43 and the propulsion device 42 is realized through the mutual cooperation of the pin hole 45 and the pin. The installation and disassembly of the stop mechanism 4 can be completed through the pin method, and the operation steps are simple. A ball 8 is rotatably installed on the placement platform 3. The provided ball 8 is beneficial for the stop plate 43 to move on the placement platform 3, making the movement of the stop plate 43 more convenient. The top of the ball 8 is in contact with the bottom of the stop plate 43. A long bolt hole 46 is opened on the mounting seat 41. The long bolt hole 46 is bolt - connected to the installation platform 2. The mutual cooperation of the long bolt hole 46 and the bolt ensures that the mounting seat 41 can timely adjust the installation position with the replaceable stop plate 43. The long bolt hole 46 is designed as an oblong hole to ensure the adjustability of the propulsion device 42 in the direction parallel to the out - chain direction of the anchor chain body 7, so that the stop mechanism 4 can be used for stopping various different - specification anchor chain bodies 7.

[0041] To ensure the smooth implementation of this solution, it should also be noted that the propulsion device 42 mentioned in this article can be one of existing automatic telescopic parts such as a cylinder telescopic rod, a hydraulic cylinder, and an electric push rod.

[0042] It should also be noted that the length of the stop plate 43 is not less than 2.5 times the distance between the two limit toolings 5, further ensuring the stopping effect of the stop plate 43 on the anchor chain body 7.

[0043] Example 2

[0044] On the basis of Example 1, please refer to Figure 1-8 As shown, the auxiliary limit mechanism 6 includes a mounting shell 61, and the mounting shell 61 is fixedly installed on the tops of the two limit toolings 5. A driving mechanism for driving the stop rod 69 and the stop baffle 43 to move simultaneously is arranged between the auxiliary limit mechanism 6 and the stop mechanism 4. The simultaneous movement of the stop rod 69 and the stop baffle 43 is realized through the arranged driving mechanism. Two mounting rods 68 are movably installed on the mounting shell 61. The stop rod 69 is installed through the arranged mounting rods 68. The stop rod 69 is fixedly installed on the mounting rods 68. The auxiliary stop operation of the anchor chain is carried out through the arranged stop rod 69. An adjusting mechanism for adjusting the distance between the two mounting rods 68 is arranged in the mounting shell 61. The distance between the two stop rods 69 is adjusted through the arranged adjusting mechanism. The adjusting mechanism includes a lead screw 62. The lead screw 62 is rotatably installed in the mounting shell 61. The rotation of the arranged lead screw 62 drives the movement of the threaded ring 63. The threaded ring 63 is threadedly connected to the lead screw 62. A slide rail 614 is fixedly installed on the inner bottom wall of the mounting shell 61. The bottom of the threaded ring 63 is slidably installed on the slide rail 614. While limiting the threaded ring 63 through the arranged slide rail 614, it is beneficial to the movement of the threaded ring 63. Two round rods 65 are fixedly installed in the mounting shell 61. The moving seats 66 are installed through the arranged round rods 65. The moving seats 66 are movably sleeved on the two round rods 65 respectively. The arranged moving seats 66 drive the mounting rods 68 to move. An actuating rod 64 is movably installed between the two moving seats 66 and the lead screw 62 respectively. When the threaded ring 63 moves, it drives the actuating rod 64 to move and further drives the moving seat 66 to move. The two mounting rods 68 are respectively fixedly installed on the two moving seats 66. The moving seat 66 is driven to move through the arranged actuating rod 64. Two rectangular slots 67 are formed in one side of the mounting shell 61. The two mounting rods 68 respectively penetrate through the two rectangular slots 67. The arranged rectangular slots 67 provide a moving space for the mounting rods 68, which is beneficial to the movement of the mounting rods 68. A spring 610 is fixedly installed between the two moving seats 66 and the inner wall of the mounting shell 61 respectively. The arranged spring 610 is beneficial to the reset of the moving seat 66. The spring 610 is sleeved outside the round rod 65.

[0045] Example 3

[0046] On the basis of Example 2, please refer to Figure 1-7As shown in the figure, the driving mechanism includes a gear 611. By arranging the gear 611, the lead screw 62 is driven to rotate. The gear 611 is fixedly installed at one end of the lead screw 62. A toothed plate 613 is fixedly installed on the stop plate 43 through a connecting rod 612. By arranging the connecting rod 612, the toothed plate 613 is driven to move simultaneously with the stop plate 43. The toothed plate 613 meshes with the gear 611. By the movement of the toothed plate 613, the gear 611 is driven to rotate. One end of the lead screw 62 close to the gear 611 rotatably penetrates through one side of the mounting shell 61.

[0047] Embodiment 4

[0048] On the basis of Embodiment 3, please refer to Figure 1-5 As shown in the figure, the limiting tooling 5 includes a support platform 51 and a mounting frame 52. Both the support platform 51 and the mounting frame 52 are fixedly installed on the ship deck 1, which is beneficial to the use of the support platform 51 and the mounting frame 52. The mounting frame 52 is fixedly installed on one side of the support platform 51. The support platform 51 is fixedly installed on one side of the placing platform 3, fixing the limiting tooling 5 and the placing platform 3 as a whole. The mounting shell 61 is fixedly installed on the two support platforms 51.

[0049] The distance between the two limiting toolings 5 is between 1.5 times the link width of the anchor chain body 7 and 2 times the link width, ensuring the limitation of the anchor chain body 7 while not hindering the movement and use of the anchor chain body 7.

[0050] The working principle of the present invention: Taking the laying of the anchor chain by a winch as an example, when the laying of the anchor chain pauses and the operation of changing the laying point starts, by finely adjusting the winch, the inner holes of two certain links are respectively aligned with the axis where the centers of the cross-sections of the stop plate 43 and the stop rod 69 are located. After the anchor chain is stable, the propulsion device 42 is started to push the stop plate 43 to move in the direction close to the anchor chain. When the stop plate 43 slowly passes through the center of the corresponding link and the end reaches the placing platform 3 on the other side of the anchor chain body 7, the propulsion device 42 can be shut down to stop pushing the stop plate 43, and the stop operation of the stop plate 43 on the anchor chain can be completed.

[0051] When the propulsion device 42 pushes the stop plate 43 to move, the toothed plate 613 is driven to move in the direction of the anchor chain simultaneously through the connecting rod 612. When the toothed plate 613 moves, the lead screw 62 is driven to rotate counterclockwise. When the lead screw 62 rotates counterclockwise, the threaded ring 63 is driven to move away from the round rod 65 on the slide rail 614. When the threaded ring 63 moves, the two movable rods 64 drive the two moving seats 66 to approach each other. Furthermore, the two stop rods 69 are driven to approach each other through the two mounting rods 68 until the two stop rods 69 slowly penetrate into the central holes of the corresponding links. When the stop plate 43 passes through the center of the corresponding link and the ends of the two stop rods 69 also come into contact, the propulsion device 42 can be shut down to perform an auxiliary stop operation on the anchor chain through the two stop rods 69.

[0052] The above has described in detail an embodiment of the present invention. However, the above content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
