[0001] The invention relates to the field of deep-sea mining deployment and recovery, and in particular to a hoisting method and a hoisting device for a deep-sea mining silo. Background Art
[0002] Marine mining is a systematic project that integrates multiple disciplines, high-tech and multiple fields. It is an important aspect of the development and utilization of marine resources. The deep-sea mining system needs to complete the deployment and recovery of all underwater mining systems on the surface support platform, including the deployment and recovery of silos.
[0003] The silo is a storage device for deep-sea polymetallic nodule slurry. When the ship crane is used to lift the silo, due to its large size and weight, it is affected by sea conditions and the heave and swaying movement of the ship. The process of deploying and recovering the silo on the water surface is complicated, the silo attitude control is difficult, and the risk of offshore operations is high. Summary of the invention
[0004] Based on the above description, the present invention provides a method for hoisting a deep-sea mining silo to solve the problems of difficulty in posture control during the existing silo hoisting process and high risk of offshore operations.
[0005] The technical solution of the present invention to solve the above technical problems is as follows: A method for hoisting a deep-sea mining silo comprises the following steps: Determine a retrieval area of the silo on the cabin deck, the retrieval area being located on one side of the placement position of the silo; At least four constant tension winches are arranged on the cabin deck and are circumferentially spaced and distributed around the periphery of the loading and unloading area; determining a status of the silo; If the silo is in the loading and unloading area, the anti-sway ropes of the four constant tension winches are connected to the silo, and the silo is moved to the outside of the ship according to the crane. When the silo reaches the water surface, the two anti-sway ropes close to the placement position are disconnected from the silo. After the silo is sent into the water, the two anti-sway ropes far from the placement position are disconnected from the silo, so that the silo is placed at the placement position. If the silo is in the deployment position, the silo is lifted by a crane, and when it reaches the water surface, the two anti-sway ropes away from the deployment position are connected to the silo. When the silo is located above the cabin deck, the two anti-sway ropes close to the deployment position are connected to the silo, so that the silo is placed in the loading and unloading area.
[0006] On the basis of the above technical solution, the present invention can also be improved as follows: Furthermore, the step of connecting the anti-sway ropes of the four constant tension winches to the silo includes: Install four eye plates corresponding to the four constant tension winches on the cabin deck one by one; The four anti-sway ropes are passed through the four hanging rings of the silo one by one and connected to the four eye plates one by one.
[0007] Further, the steps of connecting the two anti-sway ropes far from the deployment position to the silo when the silo is on the water surface, and connecting the two anti-sway ropes close to the deployment position to the silo when the silo is located above the cabin deck include: When reaching the water surface, the two anti-sway ropes far away from the deployment position are respectively connected to the two hanging rings corresponding to the silo; when the silo is located above the cabin deck, the two anti-sway ropes close to the deployment position are connected to the two hanging rings corresponding to the silo.
[0008] The present invention also provides a lifting device, which is applied to the above-mentioned lifting method of the deep-sea mining silo, and the lifting device includes a hull, a lifting crane and at least four constant tension winches, the hull has a cabin deck, and the cabin deck is provided with a loading and unloading area for placing the silo; the lifting crane is installed on the cabin deck; the four constant tension winches are circumferentially spaced and distributed on the periphery of the loading and unloading area, and the anti-sway rope of each constant tension winch is used to connect with the silo.
[0009] Furthermore, the hoisting device further comprises at least four eye plates, the four eye plates are circumferentially spaced and distributed around the periphery of the pick-up and place area, and are arranged one-to-one correspondingly to the four constant tension winches; Each of the anti-sway ropes is used to pass through each corresponding hanging ring of the silo and is connected to each corresponding eye plate.
[0010] Further, the four constant tension winches are divided into two winch groups in pairs, and the two winch groups are respectively arranged on both sides of the loading and unloading area along the width direction of the cabin deck, and the two constant tension winches of each winch group are relatively distributed along the length direction of the cabin deck; The four eye plates are divided into two eye plate groups in pairs, and the two eye plate groups are distributed on both sides of the cabin deck, and each eye plate group is located in the middle of two constant tension winches.
[0011] Furthermore, the two eye plate groups are respectively arranged on both sides of the pick-and-place area along the width direction of the cabin deck, and the two eye plates of each eye plate group are relatively distributed along the length direction of the cabin deck.
[0012] Furthermore, the winches in the two winch groups are arranged opposite to each other along the width direction of the cabin deck; The eye plates of the two eye plate groups are arranged opposite to each other along the width direction of the cabin deck.
[0013] Furthermore, the distance between each eye plate and the silo is smaller than the distance between each constant tension winch and the silo.
[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: Determine a retrieval area of the silo on the cabin deck, the retrieval area being located on one side of the placement position of the silo; arrange at least four constant tension winches on the cabin deck and circumferentially spaced around the retrieval area; and determine the state of the silo.
[0015] If the silo is in the loading and unloading area, the silo needs to be placed at the placement position. First, connect the anti-sway ropes of the four constant tension winches to the silo, and move the silo to the outside of the ship according to the lifting crane. At this time, the four constant tension winches can automatically and effectively control the state of the silo, and provide a certain tension force to the silo in four directions to prevent the silo from shaking. When reaching the water surface, the two anti-sway ropes close to the placement position are disconnected from the silo. Since only the two anti-sway ropes far from the designated position are connected to the silo, the lifting wire rope of the lifting crane generates a certain tension force toward the outside of the ship to control the posture of the silo. After the silo is sent into the water, the two anti-sway ropes far from the placement position are disconnected from the silo, so that the silo can be placed at the placement position.
[0016] Similarly, if the silo is in the deployment position, the silo is lifted by the crane, and when it reaches the water surface, the two anti-sway ropes away from the deployment position are connected to the silo. At this time, the lifting wire rope of the crane generates a certain tension force toward the inside of the ship to control the posture of the silo. When the silo is located above the cabin deck, the two anti-sway ropes close to the deployment position are connected to the silo. At this time, all four anti-sway ropes are connected to the silo, and the four constant tension winches exert tension forces in four directions on the silo to prevent the silo from shaking. So that the silo is placed in the access area. Therefore, during the entire lifting and moving process between the deployment position and the access area before entering the water, the silo can control its posture, avoid the silo from shaking, reduce the work risks of the silo's offshore deployment and recovery, and greatly improve the efficiency and safety of silo deployment and recovery during deep-sea mining operations.

[0024] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 The present invention provides a lifting device, which includes a hull 1, a crane 2 and at least four constant tension winches 3. The hull 1 has a cabin deck 11, and the cabin deck 11 is provided with a placement position for placing a silo a; the crane 2 is installed on the cabin deck 11; the four constant tension winches 3 are circumferentially spaced and distributed on the periphery of the loading and unloading area, and the anti-sway rope 31 of each constant tension winch 3 is used to connect with the silo a.
[0025] In the present invention, the four constant tension winches 3 are selectively connected to the silo a, so that the corresponding anti-sway ropes 31 have tension in the corresponding direction. In the entire lifting and moving process between the silo a before entering the water and the retrieval area, its posture can be controlled to avoid the silo a from swaying, reduce the risk of the silo a being deployed and recovered at sea, and greatly improve the efficiency and safety of the silo a deployment and recovery process during deep-sea mining operations.
[0026] Specifically, refer to Figures 1 to 4 In this embodiment, the hoisting device further comprises at least four eye plates 4, which are circumferentially spaced and distributed around the periphery of the pick-up and placement area, and are arranged one by one with the four constant tension winches 3; each anti-sway rope 31 is used to pass through each corresponding hanging ring a1 of the silo a, and is connected to each corresponding eye plate 4. Therefore, when the silo a needs to be hoisted to the placement position, each anti-sway rope 31 is convenient to be separated from the silo a, simplifying the operation, and improving the safety factor and work efficiency.
[0027] In the present invention, the circumferential distribution of the four constant tension winches 3 in the access area is not limited, as long as they can play a role in adjusting the state and avoiding shaking when the silo a is lifted. In this embodiment, the deployment position is located on one side of the access area along the width direction of the cabin deck 11. The four constant tension winches 3 are divided into two winch groups in pairs, and the two winch groups are respectively arranged on both sides of the access area along the width direction of the cabin deck 11, and the two constant tension winches 3 of each winch group are relatively distributed along the length direction of the cabin deck 11; the four eye plates 4 are divided into two eye plate groups in pairs, and the two eye plate groups are distributed on both sides of the cabin deck 11, and each eye plate group is located in the middle of the two constant tension winches 3. The constant tension winches 3 of each winch group are all subjected to tension along the width direction of the cabin deck 11, so that the two anti-sway ropes 31 in each winch group are more evenly stressed.
[0028] Specifically, in this embodiment, the two eye plate groups are respectively arranged on both sides of the loading and unloading area along the width direction of the cabin deck 11; the two eye plates 4 of each eye plate group are relatively distributed along the length direction of the cabin deck 11. When the hoisting crane 2 transports the silo a from the cabin deck 11 to the water surface, and the two anti-sway ropes 31 near the deployment position are separated from the silo a, the hoisting wire rope of the hoisting crane 2 can generate tension away from the outside of the ship, so as to more stably adjust and control the state of the silo a.
[0029] In this embodiment, the winches in the two winch groups are arranged opposite to each other along the width direction of the cabin deck 11, and the two eye plates 4 in the two eye plate groups are arranged opposite to each other along the width direction of the cabin deck 11. This allows each anti-sway rope 31 to be evenly stressed, thereby preventing one of the anti-sway ropes 31 from being broken due to excessive stress, thereby improving safety performance.
[0030] In this embodiment, the distance between each eye plate 4 and the silo a is smaller than the distance between each constant tension winch 3 and the silo a, thereby saving the use length of each anti-sway rope 31.
[0031] Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 The present invention also provides a method for hoisting a deep-sea mining silo. Based on the above hoisting structure, the hoisting method comprises the following steps: S10, determining a loading and unloading area of the silo on the cabin deck, wherein the loading and unloading area is located on one side of the placement position of the silo; S20, installing at least four constant tension winches on the cabin deck and circumferentially spaced around the periphery of the loading and unloading area; S30, determining the state of the silo; S40a, if the silo is in the loading and unloading area, connect the anti-sway ropes of the four constant tension winches to the silo, and move the silo to the outside of the ship according to the crane, and disconnect the two anti-sway ropes close to the placement position from the silo when it reaches the water surface, and disconnect the two anti-sway ropes far from the placement position from the silo after the silo is sent into the water, so that the silo is placed at the placement position; S40b. If the silo is in the deployment position, lift the silo using a crane, connect the two anti-sway ropes away from the deployment position to the silo when it reaches the water surface, and connect the two anti-sway ropes close to the deployment position to the silo when the silo is located above the cabin deck, so that the silo is placed in the loading and unloading area.
[0032] Determine a retrieval area of the silo on the cabin deck, the retrieval area being located on one side of the placement position of the silo; arrange at least four constant tension winches on the cabin deck and circumferentially spaced around the retrieval area; and determine the state of the silo.
[0033] If the silo is in the loading and unloading area, the silo needs to be placed at the placement position. First, connect the anti-sway ropes of the four constant tension winches to the silo, and move the silo to the outside of the ship according to the lifting crane. At this time, the four constant tension winches can automatically and effectively control the state of the silo, and provide a certain tension force to the silo in four directions to prevent the silo from shaking. When reaching the water surface, the two anti-sway ropes close to the placement position are disconnected from the silo. Since only the two anti-sway ropes far from the designated position are connected to the silo, the lifting wire rope of the lifting crane generates a certain tension force toward the outside of the ship to control the posture of the silo. After the silo is sent into the water, the two anti-sway ropes far from the placement position are disconnected from the silo, so that the silo can be placed at the placement position.
[0034] Similarly, if the silo is in the deployment position, the silo is lifted by the crane, and when it reaches the water surface, the two anti-sway ropes away from the deployment position are connected to the silo. At this time, the lifting wire rope of the crane generates a certain tension force toward the inside of the ship to control the posture of the silo. When the silo is located above the cabin deck, the two anti-sway ropes close to the deployment position are connected to the silo. At this time, all four anti-sway ropes are connected to the silo, and the four constant tension winches exert tension forces in four directions on the silo to prevent the silo from shaking. So that the silo is placed in the access area. Therefore, during the entire lifting and moving process between the deployment position and the access area before entering the water, the silo can control its posture, avoid the silo from shaking, reduce the work risks of the silo's offshore deployment and recovery, and greatly improve the efficiency and safety of silo deployment and recovery during deep-sea mining operations.
[0035] Further, the step S40a includes: S401a, installing four eye plates corresponding to four constant tension winches on the cabin deck; S402a, passing the four anti-sway ropes through the four hanging rings of the silo one by one, and connecting them to the four eye plates one by one.
[0036] When it is necessary to lift the silo placed in the access area to the placement position, firstly arrange four constant tension winches around the access area, then pass the four anti-sway ropes through the four corresponding hanging rings on the silo, and then connect the free ends of the four anti-sway ropes to the four eye plates. Thus, when the silo moves to the water surface, it is convenient to release the connection between the two anti-sway ropes near the placement position and the silo, and it is convenient to disconnect the two anti-sway ropes far from the placement position after the silo enters the water. In this way, the operation is simplified, the work risk is reduced, and the work efficiency is improved.
[0037] In this embodiment, the step S40b includes: S401b. When reaching the water surface, the two anti-sway ropes far away from the deployment position are respectively connected to the two hanging rings corresponding to the silo; when the silo is located above the cabin deck, the two anti-sway ropes close to the deployment position are connected to the two hanging rings corresponding to the silo.
[0038] When it is necessary to lift the silo located at the deployment position on the seabed to the retrieval area, first use a crane to lift the silo up to the water surface, and then connect the two anti-sway ropes far away from the deployment position to the two hanging rings corresponding to the silo. Since only the two anti-sway ropes far away from the deployment position are connected to the silo, the lifting wire rope of the crane is tilted toward the inside of the ship at this time, and has a tensioning force toward the inside of the ship to control the state of the silo. When the silo moves to the top of the cabin deck, the two anti-sway ropes close to the deployment position are connected to the two hanging rings corresponding to the silo, and a certain tensioning force is provided from four directions to adjust the state of the silo. There is no need to connect each anti-sway rope to each eye plate, but each anti-sway rope is directly connected to each hook of the silo, the steps are simple and the operation is convenient.
[0039] It should be noted that the connection process between each anti-sway rope and each hook of the silo is achieved by manual assistance with the help of a rope rod, which will not be described in detail here. In addition, a plurality of hanging rings are provided on the circumference of the silo, and the number of the hanging rings is greater than four, and the plurality of hanging rings are used for selective connection of the four anti-sway ropes.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
