Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for the transportation and hoisting operation of a tower barrel supporting a wind turbine unit, and particularly relates to a tower barrel hoisting and transporting device. Background Art

[0002] At present, the offshore wind power operation is gradually expanding into the deep and far sea space, and the available operation window period in the corresponding sea area also shows a fragmented trend. Therefore, in the actual operation of offshore wind power, the operation mode and motion performance of the moving equipment of the transport ship responsible for transporting and installing wind power equipment have become the key factors restricting the construction efficiency of the offshore wind power operation surface. Among them, the installation operation of the sling for the tower barrel component is most affected.

[0003] At the present stage, most of the slings equipped for the installation operation of the tower barrel supporting the wind turbine unit in the industry use bolts to connect the sling with the flange of the tower barrel to achieve a reliable connection between the sling and the tower barrel to be hoisted. However, although this connection structure and the corresponding operation method can meet the basic requirements of the current tower barrel hoisting and transportation operations, during actual operation, it is extremely difficult to dock the bolt holes of the sling at sea, and the installation time of the sling is relatively long. This not only restricts the overall installation and layout operation efficiency of the corresponding tower barrel and other offshore wind turbine unit supporting equipment, but also seriously threatens the operation safety of the corresponding staff and operating equipment, causing many adverse effects on the corresponding offshore wind power operation.

[0004] In view of this, how to optimize the hoisting and transportation operation mode of the tower barrel supporting the offshore wind turbine unit and improve its operation efficiency and safety is an important technical problem that needs to be solved by those skilled in the art at present. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tower barrel hoisting and transporting device, which can improve the hoisting and transportation operation efficiency of the tower barrel and effectively improve its operation safety.

[0006] To solve the above technical problems, the utility model provides a tower barrel hoisting and transporting device, including a sling and a bracket that can be coaxially inserted into the tower barrel. The middle part of the top surface of the bracket protrudes with a main spindle rod that is coaxially matched with the tower barrel. The top end of the main spindle rod is linked with the sling. The side part of the bracket protrudes with a plurality of guiding arms that extend radially along the tower barrel, and the guiding arms are evenly arranged at equal intervals along the circumferential direction of the tower barrel. The inner end of each guiding arm is fixedly connected to the bottom of the main spindle rod;

[0007] The outer end of the guide arm is provided with a limiting support member. The outer end face of the limiting support member can abut against the inner peripheral wall of the tower, and the top surface of the limiting support member can abut against the bottom surface of the flange of the tower. The guide arm is also provided with a limiting support drive mechanism that can drive the limiting support member to reciprocate along the extension direction of the guide arm.

[0008] Preferably, the limiting support includes a limiting section extending along the extension direction of the guide arm and a support section extending along the axial direction of the tower, the support section being located at the outer end of the limiting section, and the top end of the support section protruding from the top surface of the limiting section;

[0009] The guide arm has a guide cavity extending along its extension direction, and the support section is inserted into the guide cavity from the outer end of the guide arm.

[0010] Preferably, the limiting support drive mechanism is a hydraulic cylinder arranged in the guide cavity, and the actuating end of the hydraulic cylinder is linked to the inner end of the support section.

[0011] Preferably, a transverse support arm is connected between any two adjacent guide arms, and the two ends of the transverse support arm are respectively fixedly connected to the middle sidewall of the two adjacent guide arms.

[0012] Preferably, the bracket further includes inclined support arms arranged in a one-to-one correspondence with the guide arms. The top end of the inclined support arm is fixedly connected to the upper side wall of the main shaft, and the bottom end of the inclined support arm is fixedly connected to the middle top wall of the guide arm in a one-to-one correspondence.

[0013] Preferably, the top end of the main shaft is fixedly provided with a lifting lug that is linked to the bottom end of the sling, and the sling can be detached and assembled with the lifting lug.

[0014] Preferably, the lifting lug includes two support plates protruding axially from the top surface of the main shaft. The two support plates are symmetrically arranged radially along the main shaft and are clearance-fitted. The lifting lug also includes a lifting shaft fixedly connected between the two support plates. The axis of the lifting shaft is perpendicular to the axis of the main shaft, and the top surface of the lifting shaft and the main shaft are clearance-fitted axially along the main shaft. The bottom end of the sling is wrapped around the outer periphery of the lifting shaft and is detachably assembled with the lifting shaft.

[0015] Preferably, the sling is a strap that can slide and adapt to the outer peripheral surface of the lifting shaft.

[0016] Preferably, the outer circumferential surface of the hoisting shaft is a smooth cylindrical surface.

[0017] Preferably, the bracket is a one-piece metal structure.

[0018] Compared to the aforementioned background technology, the tower hoisting and transportation device provided by this utility model, during operation, when it is necessary to hoist or transport the tower, uses slings to place the support and its accessories into the tower from top to bottom through the tower opening, ensuring that the support and the tower are coaxially aligned, and that the limiting support is slightly lower than the flange at the tower opening; then, the limiting support drive mechanism drives the limiting support to extend from the outer end of the guide arm until the outer end face of the limiting support reliably abuts against the inner circumferential wall of the tower, thereby completing the radial limiting and locking of the tower. The support frame can be lifted moderately using slings until the top surface of the limiting support reliably abuts against the bottom surface of the flange at the tower opening, thus completing the axial limiting and locking of the tower. This completes the reliable assembly between the tower hoisting and transportation device and the tower to be processed. Afterward, the hoisting equipment connected to the other end of the slings can be used to lift the slings, thereby lifting the tower hoisting and transportation device and the tower reliably assembled on the device as a whole, so as to move the tower to the target position and complete the corresponding tower transportation or installation operation. The tower hoisting and transportation device utilizes the reliable mating and adaptation between the limiting support and the inner circumferential surface of the tower and the bottom surface of the flange to achieve reliable radial and axial limiting and locking of the tower. This ensures the reliability and accuracy of subsequent tower hoisting, installation, and transportation operations. Furthermore, no bolt alignment or other operations are required during the entire hoisting process, significantly reducing the assembly difficulty between the tower and the tower hoisting and transportation device. In particular, it reduces the difficulty of supporting operations during offshore wind turbine construction. The entire operation does not require manual intervention by personnel in component alignment and connection, making the entire operation safer and smoother. Consequently, the installation and arrangement of the corresponding offshore wind turbine tower and its supporting components are safer and more efficient.

[0019] In another preferred embodiment of this utility model, the limiting support includes a limiting section extending along the extension direction of the guide arm and a support section extending along the axial direction of the tower. The support section is located at the outer end of the limiting section, and the top end of the support section protrudes from the top surface of the limiting section. The guide arm has a guide cavity extending along its extension direction, and the support section is inserted into the guide cavity from the outer end of the guide arm. Based on the insertion and adaptation structure between the support section and the guide cavity, the guide cavity can provide reliable limiting guidance for the reciprocating movement of the limiting support, thereby ensuring the reciprocating movement accuracy of the limiting support along the extension direction of the guide arm, avoiding loosening or misalignment of the limiting support during movement, and further ensuring the abutment and adaptation effect between the limiting support and the inner circumferential surface of the tower and the bottom surface of the flange, so as to further optimize the reliability of the assembly structure between the tower hoisting and transportation device and the tower and the corresponding hoisting operation safety.

[0033] The core of this utility model is to provide a tower hoisting and transportation device, which can improve the efficiency of tower hoisting and transportation operations and effectively improve its operational safety.

[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should be noted in advance that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Furthermore, in this invention, unless otherwise explicitly specified and limited, the first feature being "on" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[0037] In addition, the terms "above," "over," and "on top" for the first feature and the second feature include the first feature being directly above or diagonally above the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" for the first feature and the second feature include the first feature being directly below or diagonally below the second feature, or simply indicating that the first feature is at a lower horizontal level than the second feature. The terms "above," "below," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0038] In specific implementation methods, in conjunction with references Figures 1 to 3 As shown, the tower hoisting and transportation device provided by this utility model includes a support 10 that can coaxially insert a sling 20 into the tower 30. A main shaft 11 that coaxially cooperates with the tower 30 is protruding from the center of the top surface of the support 10. The top of the main shaft 11 is linked to the sling 20. Several guide arms 111 that extend radially along the tower 30 are protruding from the side of the support 10. Each guide arm 111 is evenly and equidistantly arranged along the circumference of the tower 30. The inner end of the guide arm 111 is fixedly connected to the bottom of the main shaft 11.

[0039] The outer end of the guide arm 111 is provided with a limiting support 12. The outer end face of the limiting support 12 can abut against the inner peripheral wall of the tower 30, and the top surface of the limiting support 12 can abut against the bottom surface of the flange 31 of the tower 30. The guide arm 111 is also provided with a limiting support drive mechanism that can drive the limiting support 12 to reciprocate along the extension direction of the guide arm 111.

[0040] During the specific operation and use of the equipment, when it is necessary to hoist or transport the tower barrel 30, the sling 20 is used to place the support 10 and its fittings into the tower barrel 30 from top to bottom through the barrel opening of the tower barrel 30, ensuring that the support 10 and the tower barrel 30 are coaxially arranged in alignment, and making the limit support member 12 slightly lower than the flange 31 at the barrel opening of the tower barrel 30.

[0041] After that, the limit support driving mechanism is used to drive the limit support member 12 to extend from the outer end of the guide arm 111 until the outer end face of the limit support member 12 reliably abuts against the inner peripheral wall of the tower barrel 30 to complete the radial limit locking of the tower barrel 30; at this time, the sling 20 can be used to moderately lift the entire support 10 until the top surface of the limit support member 12 reliably abuts against the bottom surface of the flange 31 at the barrel opening of the tower barrel 30 to complete the axial limit locking of the tower barrel 30. In this way, the reliable assembly between the tower barrel hoisting and transporting device and the tower barrel 30 to be processed can be completed.

[0042] After that, the hoisting equipment connected to the other end of the sling 20 can be used to lift the sling 20, so as to lift the tower barrel hoisting and transporting device and the tower barrel 30 reliably assembled on the tower barrel hoisting and transporting device as a whole through the sling 20, so as to move the tower barrel 30 to the target position and complete the corresponding tower barrel 30 transportation or installation operation.

[0043] The tower barrel hoisting and transporting device realizes the reliable radial and axial limit locking of the tower barrel 30 by the reliable abutment and adaptation of the limit support member 12 with the inner peripheral surface of the tower barrel 30 and the bottom surface of the flange 31, ensuring the operation reliability and operation accuracy of the subsequent hoisting, installation and transportation of the tower barrel 30. And during the whole hoisting process, operations such as bolt alignment are not required, greatly reducing the assembly difficulty between the tower barrel 30 and the tower barrel hoisting and transporting device, especially reducing the supporting operation difficulty during the construction of offshore wind turbines. During the whole operation process, there is no need for staff to manually participate in operations such as component alignment and connection, making the whole operation process safer and smoother, and further making the installation and arrangement of the tower barrel 30 of the corresponding offshore wind turbine and its supporting components safer and more efficient.

[0044] Generally, the number of guide arms 111 is at least 3, and preferably 4 as shown in Figure 2 In this way, after the 4 guide arms 111 are arranged equidistantly in the circumferential direction, a "rice" - shaped support structure can be formed, further optimizing the stress distribution of the配合结构 between each limit support member 12 and the tower barrel 30, thereby correspondingly optimizing the assembly structure stability and structural strength between the tower barrel hoisting and transporting device and the tower barrel 30, making the subsequent hoisting, installation and transportation operations of the tower barrel 30 smoother and more stable, and ensuring the safety of related operations.

[0045] Specifically, the limiting support 12 includes a limiting section 121 extending along the extension direction of the guide arm 111 and a support section 122 extending along the axial direction of the tower 30. The support section 122 is located at the outer end of the limiting section 121, and the top end of the support section 122 protrudes from the top surface of the limiting section 121. The guide arm 111 has a guide cavity extending along its extension direction, and the support section 122 is inserted into the guide cavity from the outer end of the guide arm 111. Based on the insertion and adaptation structure between the support section 122 and the guide cavity, the guide cavity can provide reliable limiting guidance for the reciprocating movement of the limiting support 12, so as to ensure the reciprocating movement accuracy of the limiting support 12 along the extension direction of the guide arm 111, avoid the limiting support 12 from loosening or misaligning during movement, and thereby further ensure the abutment and adaptation effect between the limiting support 12 and the inner circumferential surface of the tower 30 and the bottom surface of the flange 31, so as to further optimize the reliability of the assembly structure between the tower hoisting and transportation device and the tower 30 and the corresponding hoisting operation safety.

[0046] More specifically, the limiting support drive mechanism is a hydraulic cylinder 13 arranged in the guide cavity, and the actuating end of the hydraulic cylinder 13 is linked to the inner end of the support section 122. The reciprocating motion of the hydraulic cylinder 13 is smooth and efficient, and its overall component structure is relatively reliable. This not only ensures the driving efficiency of the limiting support 12, but also improves the motion stability of the limiting support 12, thereby making the reciprocating movement of the limiting support 12 more efficient and smooth.

[0047] Of course, the limit support drive mechanism can also be other drive mechanisms capable of axial reciprocating motion, such as pneumatic cylinders or worm gear mechanisms. In practical applications, it can be flexibly selected and adjusted according to specific assembly conditions and working requirements. In principle, any mechanism that can meet the practical application needs of the tower hoisting and transportation device is acceptable.

[0048] Furthermore, a transverse support arm 112 is connected between any two adjacent guide arms 111, with both ends of the transverse support arm 112 fixedly connected to the middle sidewalls of the two adjacent guide arms 111. Each transverse support arm 112 can provide reliable transverse and lateral support for the adjacent guide arms 111 to prevent the guide arms 111 from becoming laterally loose or misaligned, thereby further improving the structural strength of each guide arm 111 and ensuring the structural stability of the corresponding components.

[0049] It is not difficult to understand that if such a choice is made... Figure 2The component structure shown has four guide arms 111 working together, and there are also four corresponding transverse support arms 112. The transverse support arms 112 work together to form a roughly quadrilateral enclosure structure. This further optimizes the overall stress distribution of the support 10, improves the overall stress resistance and structural reliability of the support 10, and makes the overall component structure of the tower hoisting and transportation device more stable, reliable and durable, and optimizes the working condition adaptability of the tower hoisting and transportation device accordingly.

[0050] Based on this, the support frame 10 also includes inclined support arms 113 arranged one-to-one with the guide arms 111. The top end of the inclined support arm 113 is fixedly connected to the upper side wall of the main shaft 11, and the bottom end of the inclined support arm 113 is fixedly connected to the middle top wall of the guide arm 111. The inclined support arm 113 can cooperate with the main shaft 11 and each guide arm 111 to form an inclined tension structure, so as to provide appropriate lifting support for each guide arm 111 and its matching limiting support 12, thereby further improving the stress resistance of the guide arm 111 and the limiting support 12 and other components, ensuring the structural strength of the assembly between the tower hoisting and transportation device and the tower 30, so as to make the corresponding tower 30 hoisting and transportation operation process more stable and safe.

[0051] On the other hand, a lifting lug 14 is fixedly installed at the top of the main shaft 11 and is linked to the bottom of the sling 20, and the sling 20 can be detached and assembled with the lifting lug 14. The lifting lug 14 can provide sufficient and reliable installation space for the sling 20 to ensure the connection strength and linkage reliability between the sling 20 and the tower hoisting and transportation device, thereby making the hoisting and transportation operation of the tower 30 more stable and reliable, and the corresponding operational safety is further improved.

[0052] Specifically, the lifting lug 14 includes two support plates 141 protruding axially from the top surface of the main shaft 11. The two support plates 141 are symmetrically arranged radially along the main shaft 11 and are clearance-fitted. The lifting lug 14 also includes a lifting shaft 142 fixedly connected between the two support plates 141. The axis of the lifting shaft 142 is perpendicular to the axis of the main shaft 11, and the top surface of the lifting shaft 142 is clearance-fitted with the top surface of the main shaft 11 axially. The bottom end of the sling 20 is wrapped around the outer periphery of the lifting shaft 142 and is detachably assembled with the lifting shaft 142.

[0053] The shaft structure of the lifting shaft 142 itself can further optimize the stress distribution at the contact point between the lifting lug 14 and the sling 20, avoiding damage to the lifting lug 14 structure or even failure of the lifting connection structure caused by excessive local stress concentration. This further improves the lifting and load-bearing capacity of the tower lifting and transportation device, ensuring its stable lifting and transportation of towers 30 of different weights and sizes.

[0054] It is easy to understand that, due to the use of a reciprocating telescopic mechanism formed by the guide arm 111 and its end limiting support 12 as the mating part with the tower 30, the tower hoisting and transportation device can adapt to the hoisting operation requirements of towers 30 with various inner diameters. In actual operation, it is only necessary to reasonably adjust the extension size of the limiting support 12 relative to the guide arm 111 to complete the mating adaptation of towers 30 of different specifications. After completing the corresponding tower hoisting and transportation operation, it is only necessary to drive the limiting support 12 to move and reset along the extension direction of the guide arm 111 through the limiting support drive mechanism to release the mating adaptation of the inner circumferential surface of the corresponding tower 30 and the bottom surface of the flange 31. This allows the tower hoisting and transportation device to be disassembled from the corresponding tower 30. Then, the tower hoisting and transportation device can be moved out of the tower 30 as a whole, and the corresponding assembly of the tower hoisting and transportation device with the next tower 30 to be processed and the subsequent hoisting and transportation operation can be carried out. This significantly improves the adaptability of the tower hoisting and transportation device to different working conditions, making its actual operation more convenient and efficient.

[0055] Furthermore, the sling 20 is a sling that can slide and adapt to the outer peripheral surface of the lifting shaft 142. Of course, the sling 20 can also be made of flexible connectors such as metal chains or ropes to ensure the connection and adaptation requirements with the lifting equipment and the tower lifting and transportation device, and to ensure the accuracy and safety of the lifting and transportation operations of the corresponding tower 30.

[0056] Correspondingly, the outer circumferential surface of the lifting shaft 142 is a smooth cylindrical surface. Thus, after the sling is reliably wound around and connected to the outer circumferential surface of the lifting shaft 142, the sling and the lifting shaft 142 can slide moderately relative to each other along the circumference of the lifting shaft 142. This allows adjustment of the engagement angle between the tower 30 mounted on the support 10 and the sling, thereby enabling moderate turning and rotation of the corresponding tower 30, or even... Figure 3 The lateral flipping arrangement shown meets the operational requirements of different working environments, thereby further improving the adaptability and ease of operation of the tower hoisting and transportation device.

[0057] Furthermore, in practical applications, the bracket 10 is a one-piece metal structure. This one-piece structure can further improve the structural strength of the bracket 10 components, optimize its stress resistance, and make its overall structure more robust, reliable, and durable.

[0058] Generally, the integrated structure of the support 10 can be achieved through a one-piece forming process such as forging or casting, or it can be achieved by machining each component of the support 10 separately and then connecting the components together using welding or other methods. Of course, this integrated structure typically refers to static connecting components such as the main shaft 11, guide arm 111, transverse support arm 112, and oblique support arm 113, but does not include moving components such as the limiting support 12 and the limiting support drive mechanism. In short, any structure that meets the actual application needs of the tower hoisting and transportation device is acceptable.

[0059] In summary, the tower hoisting and transportation device provided in this utility model, during its operation, when it is necessary to hoist or transport the tower, uses slings to place the support and its accessories into the tower from top to bottom through the tower opening, ensuring that the support and tower are coaxially aligned, and that the limiting support is slightly lower than the flange at the tower opening; then, the limiting support drive mechanism drives the limiting support to extend from the outer end of the guide arm until the outer end face of the limiting support reliably abuts against the inner circumferential wall of the tower, thereby completing the radial limiting and locking of the tower. At this point, it can... The support frame is lifted moderately using slings until the top surface of the limiting support reliably abuts against the bottom surface of the flange at the tower opening, thus completing the axial limiting and locking of the tower. This completes the reliable assembly between the tower hoisting and transport device and the tower to be processed. Afterward, the hoisting equipment connected to the other end of the slings can be used to lift the slings, thereby lifting the tower hoisting and transport device and the tower reliably assembled on the device as a whole, so as to move the tower to the target position and complete the corresponding tower transportation or installation operation. The tower hoisting and transportation device utilizes the reliable mating and adaptation between the limiting support and the inner circumferential surface of the tower and the bottom surface of the flange to achieve reliable radial and axial limiting and locking of the tower. This ensures the reliability and accuracy of subsequent tower hoisting, installation, and transportation operations. Furthermore, no bolt alignment or other operations are required during the entire hoisting process, significantly reducing the assembly difficulty between the tower and the tower hoisting and transportation device. In particular, it reduces the difficulty of supporting operations during offshore wind turbine construction. The entire operation does not require manual intervention by personnel in component alignment and connection, making the entire operation safer and smoother. Consequently, the installation and arrangement of the corresponding offshore wind turbine tower and its supporting components are safer and more efficient.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
