Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power engineering, in particular to an arm for carrying a conductor frame. Background Art

[0002] As the core component of offshore wind power projects, wind turbines consist of jackets, towers and wind turbines.

[0003] At present, during the construction of wind turbines, it is necessary to first install a jacket as the basic platform for the tower and wind turbine in the offshore construction area, and then build the tower and wind turbine on the jacket. During the jacket installation process, the operators operate the tugboat and the crane ship to work together at sea, and the crane ship lifts and tows the jacket loaded on the tugboat.

[0004] During the construction of wind turbines, offshore construction is affected by environmental factors such as wave impact, strong wind loads and seawater corrosion, resulting in a long construction period for wind turbines. On the other hand, tugboats and crane ships are on standby at the same time, increasing the cost of offshore wind power construction. Utility Model Content

[0005] In order to reduce the cost of offshore wind power construction and improve the efficiency of offshore wind power construction, the present application provides a boom for carrying a jacket.

[0006] The present application provides an arm for carrying a jacket using the following technical solution:

[0007] A boom for carrying a conductor frame includes a base, a group of rotating arms symmetrically arranged on the base, the rotating arms are parallel to each other, positioning components and steel wire ropes are arranged on opposite surfaces of the rotating arms, the positioning components are located above the steel wire ropes, the positioning components are used to connect to the tower, the steel wire ropes are used to lift the conductor frame, a group of sliding frames are symmetrically arranged between the rotating arms, the sliding frames are parallel to each other, and a number of limit assemblies are arranged on the sliding frames, and the limit assemblies are used to connect to the conductor frame.

[0008] By adopting the above technical solution, after the jacket, tower and wind turbine are installed on land to form a wind turbine, the wind turbine is put into water, the positioning assembly is connected to the tower, and the limit assembly is connected to the jacket, so that the positioning assembly and the limit assembly limit the horizontal movement of the wind turbine. Then the wire rope is connected to the top transition section of the jacket, so that the wind turbine is carried on the towing boat. When the towing boat transports the wind turbine to the operating sea area, the positioning assembly is separated from the tower, the limit assembly is separated from the jacket, and then the wire rope is extended to cooperate with the lowering of the wind turbine. When the wind turbine is completely lowered, the wire rope is separated from the wind turbine. On the one hand, the wind turbine is completed on land, shortening the construction period of the wind turbine. On the other hand, the towing boat realizes the loading and lifting functions of the wind turbine, reducing the cost of offshore wind power construction.

[0009] Preferably, a group of sliding grooves are symmetrically provided on the base along the length direction of the base, the sliding grooves are parallel to each other, a sliding block is slidingly arranged in the sliding groove, the sliding block is fixedly connected to the sliding frame, a driving motor is fixedly arranged in the sliding groove, a driving screw is fixedly arranged on the output shaft of the driving motor, the driving screw is rotatably connected to the inner wall of the sliding groove at one end away from the driving motor, and the driving screw is threadedly connected to the sliding block.

[0010] By adopting the above technical solution, the driving motor is started to drive the driving screw to rotate, the driving screw rotation drives the sliding block to move along the sliding groove, the movement of the sliding groove drives the sliding frame to move along the length direction of the base, thereby achieving the effect of the sliding frame driving the limit assembly to move on the towing boat. When the wind turbine needs to be carried, the limit assembly moves to protrude from the towing boat. When the wind turbine is not carried, the limit assembly retracts into the towing boat, reducing the overload of the towing boat.

[0011] Preferably, the limiting assembly includes a limiting seat and a group of limiting claws, the limiting seat is fixedly arranged on the sliding frame, the limiting claws are relatively arranged, and the limiting claws are rotatably connected to the limiting seat.

[0012] By adopting the above technical solution, when the limit claws rotate relative to each other, the opening between the limit claws gradually closes, and when the limit claws rotate away from each other, the opening between the limit claws gradually opens.

[0014] By adopting the above technical solution, when one of the synchronous shafts rotates, the synchronous gear on the synchronous shaft drives the other synchronous gear to rotate, and the other synchronous gear drives the other synchronous shaft to rotate, thereby achieving the effect that when one of the limit claws rotates counterclockwise, the other limit claw rotates clockwise.

[0015] Preferably, a first motor and a second motor are fixedly mounted on the limiting seat, an output shaft of the first motor is fixedly connected to one of the synchronous shafts, and an output shaft of the second motor is fixedly connected to the other synchronous shaft.

[0016] By adopting the above technical solution, when the first motor starts, the second motor does not start, and the first motor drives the synchronous shaft to rotate. When the second motor starts, the first motor does not start, and the second motor drives the synchronous shaft to rotate, thereby using the first motor and the second motor as a backup and reducing the failure of the limit clamp.

[0017] Preferably, a hydraulic telescopic rod is provided between the rotating arm and the base, the fixed end of the hydraulic telescopic rod is rotatably connected to the base, the output end of the hydraulic telescopic rod is rotatably connected to the side wall of the rotating arm, and the bottom of the rotating arm is rotatably connected to the base.

[0018] By adopting the above technical solution, when the output end of the hydraulic telescopic rod is extended and retracted, the rotating arm rotates. When the wind turbine needs to be carried, the positioning assembly moves to protrude from the towing boat. When the wind turbine is not carried, the positioning assembly retracts into the towing boat, thereby reducing the overload of the towing boat.

[0019] Preferably, the positioning assembly includes a positioning cylinder and a positioning clamp, the positioning clamps are arranged opposite to each other, the back surfaces of the positioning clamps are connected to the output end of the positioning cylinder, and the fixed end of the positioning cylinder is fixedly connected to the opposite surface of the rotating arm.

[0020] By adopting the above technical solution, when the tower is located between the positioning clamps, the output end of the positioning oil cylinder extends, so that the tower is restricted between the positioning clamps, thereby making the tower only move in the height direction.

[0021] Preferably, a guide wheel is provided under the positioning cylinder, the guide wheel is rotatably connected to the rotating arm, the wire rope is laid on the guide wheel, a winch is provided on one end of the wire rope, a lifting clamp is provided on the other end of the wire rope, the lifting clamps are arranged opposite to each other, a locking cylinder is provided between the lifting clamps, the fixed end of the locking cylinder is fixedly connected to one of the lifting clamps, and the output end of the locking cylinder is fixedly connected to the other lifting clamp.

When the wire rope lifts the lifting clamp, the lifting clamp is clamped on the jacket, thereby achieving the effect of lifting the entire wind turbine.

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] The embodiment of the present application discloses an arm for carrying a conductor rack. Figures 1 to 8, comprising a base 1, which is mounted on a towing vessel 9. A set of rotating arms 2 are symmetrically mounted on the base 1, and the rotating arms 2 are parallel to each other. Positioning assemblies 4 and steel wire ropes 3 are mounted on opposite surfaces of the rotating arms 2. The positioning assemblies 4 are located above the steel wire ropes 3. The positioning assemblies 4 are used to connect to the tower 82, and the steel wire ropes 3 are used to lift the jacket 81. A set of sliding frames 5 are symmetrically mounted between the rotating arms 2, and the sliding frames 5 are parallel to each other. Several limiting assemblies 6 are mounted on one side of the sliding frames 5, and the limiting assemblies 6 are used to connect to the jacket 81. After the jacket 81, tower 82 and wind turbine 83 are installed on land to form the wind turbine 8, the wind turbine 8 is put into the water. The positioning assembly 4 is then connected to the tower 82, and the limiting assembly 6 is connected to the jacket 81, so that the positioning assembly 4 and the limiting assembly 6 limit the horizontal movement of the wind turbine 8. After that, the steel wire ropes 3 are connected to the top transition section of the jacket 81, so that the wind turbine 8 is mounted on the towing vessel 9. After the tugboat 9 transports the wind turbine 8 to the operating sea area, the positioning assembly 4 is separated from the tower 82, the limiting assembly 6 is separated from the jacket 81, and the wire rope 3 is then extended to facilitate the lowering of the wind turbine 8. When the wind turbine 8 is completely lowered, the wire rope 3 is separated from the wind turbine 8. This allows the wind turbine 8 to be erected on land, shortening the construction period. Furthermore, the tugboat 9 performs the functions of loading and hoisting the wind turbine 8, reducing the cost of offshore wind power construction.

[0038] In order to reduce the overload situation of the towing vessel 9, refer to Figure 1 and Figure 5 A set of sliding grooves 51 are symmetrically provided on the base 1 along the length direction of the base 1, and the sliding grooves 51 are parallel to each other. Sliding blocks 53 are slidingly arranged in the sliding grooves 51, and the outer walls of the sliding blocks 53 are in contact with the inner walls of the grooves. The top wall of one sliding block 53 is welded to the bottom wall of one of the sliding frames 5, and the top wall of the other sliding block 53 is welded to the bottom wall of the other sliding frame 5. A driving motor 54 is installed in the sliding groove 51, and a driving screw 52 is installed on the output shaft of the driving motor 54. The end of the driving screw 52 away from the driving motor 54 is rotatably connected to the inner wall of the sliding groove 51, and the driving screw 52 is threadedly connected to the sliding block 53. When the driving motor 54 is started, it drives the driving screw 52 to rotate. The rotation of the driving screw 52 drives the sliding block 53 to move along the sliding groove 51. The movement of the sliding groove 51 drives the sliding frame 5 to move along the length direction of the base 1, thereby achieving the effect of the sliding frame 5 driving the limit assembly 6 to move on the towing boat 9. When the wind turbine 8 needs to be carried, the limiting assembly 6 moves to protrude from the towing vessel 9. When the wind turbine 8 is not carried, the limiting assembly 6 retracts into the towing vessel 9 to reduce the unbalanced loading of the towing vessel 9.

[0039] In order to reduce the overload situation of the towing vessel 9, refer to Figures 1 to 6The bottom of the rotating arm 2 is pivotally connected to the base 1, and a hydraulic telescopic rod 21 is installed between the rotating arm 2 and the base 1. The fixed end of the hydraulic telescopic rod 21 is pivotally connected to the base 1, and the output end of the hydraulic telescopic rod 21 is pivotally connected to the side wall of the rotating arm 2. When the output end of the hydraulic telescopic rod 21 is extended or retracted, the rotating arm 2 rotates. When the wind turbine 8 is to be loaded, the positioning assembly 4 moves to protrude from the towing vessel 9. When the wind turbine 8 is not to be loaded, the positioning assembly 4 retracts to the towing vessel 9, reducing the unbalanced loading of the towing vessel 9.

[0040] In order to achieve the effect of the jacket 81 being carried on the towing vessel 9, refer to Figures 1 to 5 The limiting assembly 6 includes a limiting seat 61 and a group of limiting claws 62. The limiting seat 61 is welded to the side wall of the sliding frame 5, and the limiting claws 62 are arranged opposite to each other. The first motor 71 and the second motor 72 are installed at the bottom of the limiting seat 61, and the first motor 71 and the second motor 72 are used as a backup. When the first motor 71 is started, the second motor 72 is not started; when the second motor 72 is started, the first motor 71 is not started. The output shaft of the first motor 71 and the output shaft of the second motor 72 both pass through the limiting seat 61, and the output shaft of the first motor 71 and the output shaft of the second motor 72 are both installed with a synchronous shaft 7. When the first motor 71 or the second motor 72 is started, one of the synchronous shafts 7 rotates, and the synchronous gear 73 on the synchronous shaft 7 drives the other synchronous gear 73 to rotate, and the other synchronous gear 73 drives the other synchronous shaft 7 to rotate, so that one of the limiting claws 62 rotates counterclockwise and the other limiting claw 62 rotates clockwise. When the limiting claws 62 rotate relative to each other, the opening between the limiting claws 62 gradually closes; when the limiting claws 62 rotate away from each other, the opening between the limiting claws 62 gradually opens. When the jacket 81 is loaded onto the towing vessel 9, the jacket 81 is inserted between the limiting claws 62, and the opening between the limiting claws 62 is closed.

[0041] In order to achieve the effect of the tower 82 being mounted on the towing vessel 9, refer to Figure 6 and Figure 7 The positioning assembly 4 includes a positioning cylinder 41 and a positioning clamp 42. The positioning clamps 42 are arranged opposite each other, with the back of the positioning clamps 42 connected to the output end of the positioning cylinder 41. The fixed end of the positioning cylinder 41 is welded to the opposite surface of the rotating arm 2. When the tower 82 is located between the positioning clamps 42, the output end of the positioning cylinder 41 extends, confining the tower 82 between the positioning clamps 42, thereby limiting the tower 82 to movement in the height direction.

[0042] In order to achieve the effect of hoisting the wind turbine 8, refer to Figures 1 to 8A guide wheel 31 is installed below the positioning cylinder 41, and the guide wheel 31 is rotatably connected to the rotating arm 2. The wire rope 3 is mounted on the guide wheel 31, and a winch 32 is installed on one end of the wire rope 3. The winch 32 is installed on the towing boat 9. A lifting clamp 33 is hung on the other end of the wire rope 3, and the lifting clamps 33 are arranged relative to each other. A locking cylinder 34 is installed between the lifting clamps 33, and the fixed end of the locking cylinder 34 is welded to one of the lifting clamps 33, and the output end of the locking cylinder 34 is welded to the other lifting clamp 33. After the top of the conductor frame 81 passes through the lifting clamps 33, the output end of the locking cylinder 34 is shortened, so that the lifting clamps 33 are close to each other. When the wire rope 3 lifts the lifting clamp 33, the lifting clamp 33 is clamped on the conductor frame 81, thereby achieving the effect of lifting the wind turbine 8.

[0043] The implementation principle of a boom for carrying a jacket in an embodiment of the present application is as follows: after the jacket 81, tower 82 and wind turbine 83 are installed on land to form a wind turbine 8, the wind turbine 8 is put into the water. Then, the positioning assembly 4 is connected to the tower 82, and the limiting assembly 6 is connected to the jacket 81, so that the positioning assembly 4 and the limiting assembly 6 limit the horizontal movement of the wind turbine 8. After that, the wire rope 3 is connected to the top transition section of the jacket 81, so that the wind turbine 8 is carried on the towing vessel 9. After the towing vessel 9 transports the wind turbine 8 to the operating sea area, the positioning assembly 4 is separated from the tower 82, the limiting assembly 6 is separated from the jacket 81, and then the wire rope 3 is extended to cooperate with the lowering of the wind turbine 8. When the wind turbine 8 is completely lowered, the wire rope 3 is separated from the wind turbine 8. On the one hand, the wind turbine 8 is built on land, which shortens the construction period of the wind turbine 8. On the other hand, the towing ship 9 realizes the loading and lifting functions of the wind turbine 8, reducing the cost of offshore wind power construction.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
