Description

Technical Field

[0001] The present application relates to the technical field of offshore wind power equipment transportation, and in particular to an offshore wind power equipment transportation auxiliary device. Background Art

[0002] Offshore wind power equipment is a new type of power generation equipment. It can be installed at sea to generate electricity through wave potential energy and wind energy. It consists of wind turbines, brackets, submarine cables and converters. The above components need to be assembled at the construction site. Before the power generation equipment is installed, it needs to be transported to the construction site by large ships.

[0003] The above-mentioned submarine cable is wound on a reel to form a cable reel, and a through cavity structure is opened in the middle of the reel. Due to the strong wind and waves at sea during shipping, the cable reel may capsize on the deck. Therefore, in order to limit the cable reel and reduce the risk of cable reel capsizing, the cable reel is often fixed and limited during transportation. For example, a steel cylinder revetment structure marine transportation fixing device with publication number CN108974575A includes a fixed seat, a fixed bottom plate, a hydraulic oil pump, and a controller. A steel cylinder revetment is arranged above the fixed seat, and a fixed bottom plate is arranged below the fixed seat. A second hydraulic cylinder and a second fixed block are arranged on the inner side of the steel cylinder revetment above the fixed seat, and a second pressure sensor is arranged on the second fixed block. A first fixed block is arranged on the outer side of the steel cylinder revetment above the fixed seat, and a control panel and a protective door are arranged on the front of the fixed seat, and the control panel is located behind the protective door. The prior art has a simple structure and is easy to use and operate. It can conveniently fix the steel cylinder revetment, and the fixing effect is better, thereby improving the practicality of the steel cylinder revetment structure marine transportation fixing device.

[0004] The above-mentioned prior art is aimed at the steel cylinder revetment, which is heavy. The cable reel mentioned in the present invention is also heavy and the reel for winding the submarine cable is also similar to the steel cylinder revetment. After the first fixed block is moved outward a certain distance, the cable reel can also be limited. However, the above-mentioned prior art still has some defects: the above-mentioned patent application only limits and fixes the side of the steel cylinder revetment close to the device when limiting and fixing the steel cylinder revetment, and the end of the steel cylinder revetment away from the device is not subject to any restraint force. In addition, due to the shaking of the ship due to waves during shipping, the end of the steel cylinder revetment away from the device may cause the entire steel cylinder revetment to shake due to inertia, which leads to the risk of shaking or even capsizing of the steel cylinder revetment during transportation, and at the same time causes damage to the device, affecting the transportation effect of the steel cylinder revetment.

[0035] The following is combined with Figures 1 to 10 This application is described in further detail.

[0036] An embodiment of the present application discloses an auxiliary device for transporting offshore wind power equipment, which can increase the stability of cables during offshore transportation and avoid the possibility of shaking or even capsizing. Embodiment 1

[0037] See also Figure 1 and Figure 2 An offshore wind power equipment transportation auxiliary device includes a circular auxiliary frame 1 connected to the hull deck, a limiting rod 2 for limiting and fixing a cable reel 400 is installed on the upper end surface of the auxiliary frame 1, and a plurality of limiting grooves 3 matching with connecting bolts 401 are evenly opened on the upper end surface of the auxiliary frame 1 in a circumferential direction.

[0038] There are multiple limit rods 2 that match the limit grooves 3 one by one. A plurality of limit blocks 21 are evenly arranged on the circumferential surface of the limit rod 2 and on one side close to the corresponding limit groove 3 along its length direction. A ring plate 22 matching with it is jointly arranged on the side of the limit rod 2 away from the auxiliary frame 1.

[0039] The limit rod 2 and the limit block 21 cooperate with each other to perform internal support and limit processing on the cable reel 400. The multiple limit blocks 21 cooperate with each other to ensure that the limit rod 2 supports and limits the cable reel 400 evenly, avoiding the risk of shaking or even overturning of the cable reel 400 due to uneven force, thereby improving the stability of the cable reel 400 during transportation.

[0040] In order to facilitate the removal of the cable from the roller, the roller is usually fixed on an existing rotating frame during actual use. When the cable needs to be extracted, the roller can release the cable by rotating with the rotating frame. In order to facilitate the fixing of the roller on the existing rotating frame, multiple connecting bolts 401 are evenly installed on both sides of the roller. During specific work, the cable reel 400 is lifted by existing lifting equipment (crane, etc.) and the cable reel 400 is moved to the side of the limit rod 2 away from the auxiliary frame 1. At this time, the cavity structure is passed through the limit rod 2 and the cable reel 400 is just in contact with the auxiliary frame 1.

[0041] The cable reel 400 is then driven to rotate by an external driving force (such as human pushing). During the rotation of the cable reel 400, the connecting bolt 401 rotates synchronously. When the connecting bolt 401 coincides with the limiting groove 3, a sound of the connecting bolt 401 moving to the inside of the limiting groove 3 is heard, and the rotation of the cable reel 400 stops. The cable reel 400 is now placed on the auxiliary frame 1. Therefore, the connecting bolt 401 and the limiting groove 3 cooperate with each other to pre-limit the cable reel 400, thereby avoiding relative rotation of the cable reel 400 on the auxiliary frame 1 in the subsequent process of limiting and fixing, thereby improving the stability of the cable reel 400 in the subsequent limiting and fixing process.

[0042] The length of the limit groove 3 is long enough, and when the limit block 21 is pressed against the cable reel 400, the cable reel 400 may move on the auxiliary frame 1, so that the cable reel 400 drives the connecting bolt 401 to move freely inside the limit groove 3 during the movement, thereby giving way to the connecting bolt 401 during the movement.

[0043] See also Figures 2 to 4 A driving groove 23 is provided inside the limit rod 2 along its length direction, and the end of the limit block 21 away from the corresponding limit groove 3 is arranged inside the driving groove 23, and an inclined surface is provided at the end of the limit block 21 located inside the driving groove 23. A driving rod 24 extending along the length direction of the limit rod 2 is provided inside the driving groove 23, and linkage blocks 25 corresponding to the inclined surfaces are installed on the driving rod 24, which cooperate with the inclined surfaces to make the limit block 21 move along its length direction, and the end of the linkage block 25 away from the driving rod 24 abuts against the corresponding inclined surface. A fixing protrusion is provided on the side of the limit block 21 close to the auxiliary frame 1, and a reset spring 26 is installed between the fixing protrusion and the inner wall of the driving groove 23 to reset the limit block 21.

[0044] A limit link 27 extending along the length direction of the limit rod 2 is installed on the auxiliary frame 1 and between adjacent limit rods 2, which limits the annular plate 22, and the limit link 27 slides with the annular plate 22. A driving cylinder 28 is installed in the middle of the auxiliary frame 1 to drive the annular plate 22 to move along the length direction of the limit rod 2. The telescopic end of the driving cylinder 28 is connected to the inner side wall of the annular plate 22 through a plurality of connecting protrusions evenly distributed along the circumference of the auxiliary frame 1.

[0045] The driving rod 24 is slidably connected to the end of the limiting rod 2 away from the auxiliary frame 1. A connecting round block 241 is installed at the end of the driving rod 24 located outside the driving groove 23. A return spring 242 is provided between the driving rod 24 and the corresponding connecting round block 241 to reset the driving rod 24. The end of the return spring 242 close to the annular plate 22 is connected to the corresponding connecting round block 241, and the end of the return spring 242 away from the annular plate 22 is connected to the corresponding limiting block 21.

[0046] During specific operation, when the cable reel 400 is placed on the auxiliary frame 1, the driving cylinder 28 is started. During the starting process of the driving cylinder 28, its telescopic end drives the annular plate 22 to move toward the side of the auxiliary frame 1 through the connecting protrusion. During the movement of the annular plate 22, it abuts against the connecting round block 241 and drives the driving rod 24 to move toward the side of the auxiliary frame 1. At this time, the reset spring 26 is compressed, and the driving rod 24 synchronously drives the linkage block 25 to move during the movement. During the movement of the linkage block 25, it abuts against the inclined surface and drives the limit block 21 to move in the direction of the corresponding limit groove 3. During the movement of the limit block 21, it abuts against the cable reel 400 to perform internal support and limit processing on the cable reel 400. Multiple limit blocks 21 cooperate with each other to make the internal force of the cable reel 400 uniform, thereby avoiding the risk of instability of the cable reel 400 due to the end of the cable reel 400 away from the auxiliary frame 1 not being stressed, thereby improving the stability of the cable reel 400 during transportation.

[0047] The reset spring 26 can reset the limit block 21 when the transportation is completed and the cable reel 400 is released from the limit, the return spring 242 can reset the drive rod 24 when the transportation is completed and the cable reel 400 is released from the limit, and the limit link 27 limits the annular plate 22 during the transportation of the cable reel 400 to prevent the force on the annular plate 22 from being completely concentrated on the telescopic end of the drive cylinder 28 to cause damage to the drive cylinder 28, and acts as a force divider for the drive cylinder 28.

[0048] See also Figure 3 A rectangular groove 29 is formed at one end of the limit rod 2 away from the auxiliary frame 1, and a rectangular block 20 corresponding to the rectangular groove 29 is installed on the side of the annular plate 22 close to the auxiliary frame 1, and a plurality of clamping protrusions 211 are evenly arranged on the side of the limit block 21 away from the driving rod 24.

[0049] When the limit block 21 is tightly against the cable reel 400, the rectangular block 20 enters the rectangular groove 29, and then the annular plate 22 can limit and fix the end of the limit rod 2 away from the auxiliary frame 1 through the cooperation between the rectangular block 20 and the rectangular groove 29, thereby ensuring that the end of the limit rod 2 away from the auxiliary frame 1 will not shake due to the sea breeze during transportation, thereby ensuring the stability of the limit rod 2 during transportation. The roller is generally a wooden structure, so when the limit block 21 is against the cable reel 400, the snap-in protrusion 211 can be embedded in the wooden inner wall of the roller, thereby further reducing the possibility of relative rotation of the cable reel 400 during transportation. At the same time, the snap-in protrusion 211 also limits the cable reel 400 in the length direction of the limit rod 2, thereby preventing the cable reel 400 from shaking back and forth along the limit rod 2 during transportation.

[0050] See also Figures 5 to 7 , since most of the ships transporting offshore wind power equipment are large, when the ships are affected by wind and waves at sea, although the swaying frequency is slow, the swaying amplitude is large. In order to reduce the rigid impact of the cable reel 400 on the limit rod 2, it is necessary to perform force distribution on the limit rod 2 when transporting the cable reel 400 to unload the limit rod 2. Specifically, a yield groove 210 is provided at one end of the limit rod 2 close to the auxiliary frame 1, and a yield connecting groove 212 corresponding to the yield groove 210 is provided on the auxiliary frame 1. A return block 213 is slidably arranged inside the yield groove 210 to pull the cable reel 400, and a connecting spring rod 215 is installed between the return block 213 and the corresponding yield groove 210 to reset the return block 213. The end of the return block 213 away from the limit rod 2 passes through the yield connecting groove 212 (see Figure 8 ).

[0051] A reversing motor 11 is installed on the side of the auxiliary frame 1 away from the limit rod 2 through a motor seat, a fixed frame 12 is installed on the end of the output shaft of the reversing motor 11 away from the auxiliary frame 1, a telescopic cylinder 13 is installed on the end of the fixed frame 12 away from the auxiliary frame 1, a linkage plate 14 is installed on the end of the return block 213 away from the limit rod 2, and a T-shaped linkage connecting plate 15 is commonly arranged between adjacent linkage plates 14, and both ends of the horizontal section of the linkage connecting plate 15 are respectively slidably arranged on the side of the corresponding linkage plate 14 close to the reversing motor 11, and the end of the vertical section of the linkage connecting plate 15 away from its horizontal section is slidably arranged on the auxiliary frame 1.

[0052] A connecting ball 16 is installed on the telescopic end of the telescopic cylinder 13 , and a spherical groove 17 matching with the connecting ball 16 is provided in the middle of the side of the linkage plate 14 close to the reversing motor 11 and the middle of the side of the linkage connecting plate 15 close to the reversing motor 11 .

[0053] During specific operation, when the ship sways along the directions relative to the two limit rods 2, the cable reel 400 sways along the vertical plane formed by the two limit rods 2. When the cable reel 400 moves toward the limit rod 2 on one side, the limit rod 2 on the other side is subjected to an increased lateral force. At this time, the reversing motor 11 is started. During the rotation of the output shaft of the reversing motor 11, the telescopic end of the telescopic cylinder 13 is driven by the fixed frame 12 to move to the side of the linkage plate 14 corresponding to the limit rod 2 where the lateral force increases. The telescopic cylinder 13 is started. During the movement of the telescopic end of the telescopic cylinder 13, the connecting ball 16 is driven to move to the corresponding spherical groove 17. The telescopic end of the telescopic cylinder 13 is connected to the connecting ball 1 6 cooperates with the spherical groove 17 to drive the corresponding linkage plate 14 to move. During the movement of the linkage plate 14, the return block 213 is simultaneously driven to move. At this time, the connecting spring rod 215 is stretched. When the return block 213 contacts the cable reel 400, the linkage plate 14 drives the corresponding return block 213 to have a tendency to move. At this time, the end of the return block 213 away from the corresponding linkage plate 14 drives the cable reel 400 to have a tendency to move in the opposite direction of the lateral force exerted on the limit rod 2, so that the corresponding return block 213 can balance the lateral force exerted on the limit rod 2, reduce the possibility of the limit rod 2 being broken due to excessive lateral force exerted on it for a long time, and improve the service life of the limit rod 2.

[0054] When the ship sways along the direction of two adjacent limit rods 2, the cable reel 400 sways between the two adjacent limit rods 2. At this time, the horizontal forces on the two adjacent limit rods 2 increase, and the reversing motor 11 is started. During the rotation of the output shaft of the reversing motor 11, the telescopic end of the telescopic cylinder 13 is driven to move to the side of the linkage connecting plate 15 corresponding to the two limit rods 2 through the fixed frame 12. During the movement of the telescopic end of the telescopic cylinder 13, the connecting ball 16 is driven to move to the corresponding spherical groove 17. The telescopic end of the telescopic cylinder 13 cooperates with the spherical groove 17 to drive the corresponding linkage connecting plate 15 to move. During the movement of the linkage connecting plate 15, the corresponding The two corresponding linkage plates 14 move, and the corresponding return blocks 213 are synchronously driven to move during the movement of the adjacent linkage plates 14. At this time, the connecting spring rods 215 are stretched. When the return blocks 213 are in contact with the cable reel 400, the linkage plates 14 drive the corresponding return blocks 213 to have a tendency to move. At this time, the end of the return block 213 away from the corresponding linkage plate 14 drives the cable reel 400 to have a tendency to move in the opposite direction of the lateral force exerted on the limit rod 2, and then the corresponding return blocks 213 can balance the lateral force exerted on the limit rod 2, reduce the possibility of the limit rod 2 being broken due to excessive lateral force exerted on it for a long time, and improve the service life of the limit rod 2.

[0055] The connecting spring rod 215 used therein resets the return block 213 after the transportation is completed, ensuring that the return block 213 can be reset to the inside of the clearance groove 210, thereby reducing the possibility of the return block 213 extending out of the clearance groove 210 and causing the cable reel 400 to collide with the return block 213 when the cable reel 400 is subsequently re-lifted.

[0056] A plurality of support blocks connected to the hull deck are evenly installed circumferentially on the side of the auxiliary frame 1 away from the limit rod 2. The support blocks can be welded to the hull plywood during use. The support blocks can provide operating space for components such as the reversing motor 11 installed on the side of the auxiliary frame 1 away from the limit rod 2.

[0057] See also Figure 8 In order to prevent the cables from scattering during transportation, the arc plate 112 designed in the present invention can limit the cables. Specifically, a plurality of vertical racks 18 are evenly installed on one side of the auxiliary rack 1 close to the limit rod 2. The vertical racks 18 are all slidably provided with moving rods 19 extending along the length direction thereof. The moving rods 19 on the same vertical rack 18 are jointly installed with an arc plate 112 on one end close to the limit rod 2.

[0058] A connecting rope 10 symmetrically arranged along the length direction of the vertical frame 18 is installed on the side of the arc plate 112 away from the limiting rod 2, driving the arc plate 112 to move. A vertical connecting frame 110 is slidably arranged on the side of the auxiliary frame 1 close to the limiting rod 2. A hook 111 cooperating with the connecting rope 10 is rotatably installed on the vertical frame 18 to wind the connecting rope 10.

[0059] The vertical frame 18 is provided with an elastic telescopic rod, and one end of the elastic telescopic rod away from the vertical frame 18 is connected to the corresponding arc plate 112, and the elastic telescopic rod can reset the arc plate 112. In specific operation, when the support limit in the cable coil 400 is completed, the two hooks 111 are driven to rotate by a belt transmission method through an external driving motor (not shown in the figure). Since the belt transmission method is a known common sense, it will not be described in detail. During the rotation of the hook 111, the connecting rope 10 is twisted to make the connecting rope 10 entangled. At this time, the arc plate 112 on the corresponding connecting rope 10 is facing the cable. The cable reel 400 moves, and the vertical connecting frame 110 slides synchronously to ensure that the connecting rope 10 is always in contact with the curved plate 112, and the elastic telescopic rod is stretched. When the curved plate 112 is tightly against the cable, the hook 111 stops rotating. At this time, the curved plate 112 can limit the cable to prevent the cable from scattering during transportation, and to prevent the cable from scattering at will to ensure the winding effect of the cable. At the same time, the curved plate 112 can also protect the cable to prevent the cables from colliding with each other during transportation, which may cause damage to the metal wires inside the cable and affect the conductivity of the cable, thereby improving the quality of the cable.

[0060] At the same time, when the arc plate 112 moves to the working position, the arc plate 112 can also limit the roller to prevent the cable reel 400 from shaking along the extension direction of the limiting rod 2. When the cable transportation is completed, the hook 111 is rotated in the reverse direction to loosen the connecting rope 10. At this time, the elastic telescopic rod synchronously drives the arc plate 112 to reset.

[0061] See also Fig. 9 A pressure sensor is installed on one side of the limit block 21 close to the corresponding limit groove 3, and the pressure sensor, the telescopic cylinder 13 and the reversing motor 11 are electrically connected to each other through the central control component.

[0062] The central control component includes a central control panel arranged on the auxiliary frame 1, buttons arranged on the central control panel, and a central control unit arranged inside the central control panel, wherein the central control unit includes a central control module, a button control module electrically connected to the central control module, a pressure sensor module electrically connected to the central control module, a cylinder control module electrically connected to the central control module, and a motor control module electrically connected to the central control module.

[0063] The button control module is electrically connected to the button, the pressure sensing module is electrically connected to the pressure sensor, the cylinder control module is electrically connected to the telescopic cylinder 13 , and the motor control module is electrically connected to the reversing motor 11 .

[0064] The pressure sensor is not shown in the figure. When it is working, turn on the button, the button transmits the signal to the button control module, and then the button control module processes the signal and transmits it to the central control module. At this time, the central control module is turned on. When the reading of the pressure sensor of a single limit rod 2 increases, it means that the lateral force on the limit rod 2 increases. At this time, the pressure sensing module receives the signal of the pressure sensor and transmits the processed signal to the central control module. The central control module transmits the processed signal to the motor control module. The motor control module transmits the processed signal to the reversing motor 11. The reversing motor 11 starts and drives the fixed frame 12 to rotate a specified angle so that the telescopic end of the telescopic cylinder 13 rotates to the linkage plate 14 corresponding to the limit rod 2. At the same time, the central control module processes the signal and transmits it to the cylinder control module. The cylinder control module receives the processed signal and transmits the processed signal to the telescopic cylinder 13. At this time, the telescopic end of the telescopic cylinder 13 cooperates with the spherical groove 17 through the connecting ball 16 to drive the linkage plate 14 to move.

[0065] When the readings of the pressure sensors corresponding to the adjacent limit rods 2 all increase, it means that the lateral forces acting on the adjacent limit rods 2 all increase, and the pressure sensing module receives the signal of the pressure sensor and transmits the processed signal to the central control module, which processes the signal and transmits it to the motor control module, which processes the signal and transmits it to the reversing motor 11, and the reversing motor 11 starts to drive the fixed frame 12 to rotate a specified angle so that the telescopic end of the telescopic cylinder 13 rotates to the linkage connecting plate 15 corresponding to the limit rod 2. At the same time, the central control module processes the signal and transmits it to the cylinder control module, which receives the processed signal and transmits it to the telescopic cylinder 13, and at this time, the telescopic end of the telescopic cylinder 13 cooperates with the spherical groove 17 through the connecting ball 16 to drive the linkage connecting plate 15 to move.

[0066] Therefore, the above method can realize intelligent balance of the force on the limit rod 2, and the timeliness is strong. Embodiment 2

[0067] Reference Fig.10 On the basis of the first embodiment, in order to further improve the stability of the cable reel 400 during transportation, the arc plate 112 can be fixed on the vertical frame 18 through the cooperation of the sealing block 183 and the moving rod 19, and then the arc plate 112 can also perform external clamping and limiting processing on the cable reel 400. Specifically, a cavity 181 is opened inside the vertical frame 18, and an air inlet hole 182 matching the cavity 181 is opened on the side wall of the vertical frame 18. A sealing block 183 symmetrically distributed along the length direction of the vertical frame 18 is slidably arranged inside the cavity 181. A conical protrusion 184 is arranged on the side of the sealing block 183 close to the corresponding moving rod 19, and a rubber pad 185 matching the conical protrusion 184 is arranged on the opposite side of the moving rod 19 on the same vertical frame 18.

[0068] It is connected to the air inlet 182 through an existing pipeline (not shown in the figure), and then gas is pumped into the air inlet 182 through the existing pipeline. During specific operation, when the arc plate 112 is tightly against the cable reel 400, gas is pumped into the existing pipeline, and the gas flows into the air inlet 182 through the existing pipeline, and the gas flows to the cavity 181 through the air inlet 182. At this time, the gas inside the cavity 181 expands and drives the sealing block 183 to move away. During the movement of the sealing block 183, the conical protrusion 184 is driven to embed into the corresponding rubber pad 185, and then the sealing block 183 cooperates with the conical protrusion 184 and the rubber pad 185 to fix the moving rod 19 on the vertical frame 18, so that the moving rod 19 fixed on the vertical frame 18 cooperates with the arc plate 112 to play an external clamping and limiting role on the cable reel 400, and at the same time reduces the pressure on the connecting rope 10 when the arc plate 112 is subjected to force, thereby reducing the force loss of the connecting rope 10.

[0069] Therefore, the cable reel 400 is fixed and limited by the cooperation between the above-mentioned inner support and the outer clamp, thereby ensuring the stability of the cable reel 400 during the marine transportation.

[0070] The implementation principle of the present invention is:

[0071] (1): The cable reel 400 is lifted by the existing lifting equipment (hoist, etc.) and the cable reel 400 is moved to the side of the limit rod 2 away from the auxiliary frame 1. At this time, the cavity structure is passed through the limit rod 2 and the cable reel 400 is just in contact with the auxiliary frame 1. The cable reel 400 is driven to rotate by an external driving force (human push, etc.). During the rotation of the cable reel 400, the connecting bolt 401 rotates synchronously. When the connecting bolt 401 coincides with the limit groove 3, the sound of the connecting bolt 401 moving to the inside of the limit groove 3 is heard, and the rotation of the cable reel 400 stops. The cable reel 400 is now placed on the auxiliary frame 1.

[0072] (2): At this time, the driving cylinder 28 is started. During the starting process of the driving cylinder 28, its telescopic end drives the annular plate 22 to move toward the side of the auxiliary frame 1 through the connecting protrusion. During the movement of the annular plate 22, it abuts against the connecting round block 241 and drives the driving rod 24 to move toward the side of the auxiliary frame 1. At this time, the reset spring 26 is compressed, and the driving rod 24 drives the linkage block 25 to move synchronously during the movement. During the movement of the linkage block 25, it abuts against the inclined surface and drives the limit block 21 to move toward the side of the corresponding limit groove 3. During the movement of the limit block 21, it abuts against the cable reel 400 to perform internal support and limit processing on the cable reel 400.

[0073] (3): When the ship sways along the direction relative to the two limit rods 2, the cable reel 400 sways along the vertical plane formed by the two limit rods 2. When the cable reel 400 moves toward the limit rod 2 on one side, the limit rod 2 on the other side is subjected to an increased lateral force. At this time, the reversing motor 11 is started. During the rotation of the output shaft of the reversing motor 11, the telescopic end of the telescopic cylinder 13 is driven by the fixed frame 12 to move to the side of the linkage plate 14 corresponding to the limit rod 2 where the lateral force increases. The telescopic cylinder 13 is started. During the movement of the telescopic end of the telescopic cylinder 13, the connecting ball 16 is driven to move to the corresponding spherical groove 17. Movement, the telescopic end of the telescopic cylinder 13 cooperates with the connecting ball 16 and the spherical groove 17 to drive the corresponding linkage plate 14 to move. During the movement of the linkage plate 14, the return block 213 is synchronously driven to move. At this time, the connecting spring rod 215 is stretched. When the return block 213 contacts the cable reel 400, the linkage plate 14 drives the corresponding return block 213 to have a tendency to move. At this time, the end of the return block 213 away from the corresponding linkage plate 14 drives the cable reel 400 to have a tendency to move in the opposite direction of the lateral force exerted on the limit rod 2, and then the corresponding return block 213 can balance the lateral force exerted on the limit rod 2.

[0074] (4): When the ship sways along the direction of two adjacent limit rods 2, the cable reel 400 sways between the two adjacent limit rods 2. At this time, the horizontal forces on the two adjacent limit rods 2 increase. The reversing motor 11 is started. During the rotation of the output shaft of the reversing motor 11, the telescopic end of the telescopic cylinder 13 is driven to move to the side of the linkage connecting plate 15 corresponding to the two limit rods 2 through the fixed frame 12. During the movement of the telescopic end of the telescopic cylinder 13, the connecting ball 16 is driven to move to the corresponding spherical groove 17. The telescopic end of the telescopic cylinder 13 drives the corresponding linkage connecting plate 15 through the cooperation between the connecting ball 16 and the spherical groove 17. 5 moves, and the linkage connecting plate 15 synchronously drives the corresponding two linkage plates 14 to move during the movement. The adjacent linkage plates 14 synchronously drive the corresponding return blocks 213 to move during the movement. At this time, the connecting spring rods 215 are stretched. When the return blocks 213 are in contact with the cable reel 400, the linkage plates 14 drive the corresponding return blocks 213 to have a tendency to move. At this time, the end of the return block 213 away from the corresponding linkage plate 14 drives the cable reel 400 to have a tendency to move in the opposite direction of the lateral force exerted on the limit rod 2, so that the corresponding return blocks 213 can balance the lateral force exerted on the limit rod 2.

[0075] (5): After the support limit is completed in the cable reel 400, the two hooks 111 are driven to rotate by an external drive motor (not shown in the figure) through a belt transmission method. During the rotation of the hook 111, the connecting rope 10 is twisted to make the connecting rope 10 entangled. At this time, the arc plate 112 on the corresponding connecting rope 10 moves toward the cable reel 400. When the arc plate 112 is tightly against the cable, the hook 111 stops rotating. At this time, the arc plate 112 can limit the cable.
