Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power, and in particular to a loading and unloading buffer tool, a static-to-dynamic docking method, and a static-to-dynamic disassembly method. Background Art

[0002] At present, the construction process of floating wind turbines is mainly to assemble the wind turbines on the floating foundation by crane at the dock, and then transport the whole to the machine site by wet towing. Due to the high weight and height of the affordable large-capacity units, there are currently no larger and more suitable cranes on the market that can assemble large-capacity units at the dock. Even if the crane resources exist, the carrying capacity of the dock is very limited, and there are very few docks that can meet such a large carrying capacity. Furthermore, after the floating wind turbine is installed at the dock, it is necessary to tow the floating foundation and the wind turbine from the dock to the offshore machine site over a long distance. If strong convective weather or typhoons are encountered during the towing process, the transportation risk is very high and the consequences will be disastrous. At the same time, the existing floating wind turbine replacement plan is to tow the entire floating body and wind turbine to the dock for large component replacement, which makes the maintenance cost of the floating wind turbine very high.

[0003] It can be expected that in the future, the installation and operation of large-capacity floating wind turbines at offshore sites will be the mainstream method. However, the installation and operation of offshore sites will face a static-to-dynamic installation condition when using a self-elevating platform. Due to the shaking of the floating foundation, the docking flanges between the unit towers may be damaged by collision.

[0004] Therefore, how to provide a loading and unloading buffer tooling that can safely realize the installation and operation and maintenance of floating wind turbines at offshore machine sites and minimize the risk of tower flange collision is a technical problem that technical personnel in this field urgently need to solve.

[0046] The present invention provides a loading and unloading buffer tool 1, which is used for docking installation or disassembly of a static component 01 and a dynamic component 02;

[0047] The loading and unloading buffer tooling 1 includes a bearing mechanism 11, a rotating mechanism 12, a lifting mechanism 13 and a climbing mechanism 14. The rotating mechanism 12 includes a first transmission part 12a and a second transmission part 12b that can rotate relatively. The lower end of the lifting mechanism 13 is connected to the first transmission part 12a, and the upper end of the lifting mechanism 13 is connected to the bearing mechanism 11. The climbing mechanism 14 is connected to the second transmission part 12b. The bearing mechanism 11, the static component 01 and the dynamic component 02 are all provided with centering components.

[0048] During operation, the loading and unloading buffer tooling 1 is slidably installed on the outer periphery of the dynamic component 02, that is, the loading and unloading buffer tooling 1 and the dynamic component 02 are limited to each other in the circumferential direction and can slide relatively in the axial direction. The climbing mechanism 14 can drive the loading and unloading buffer tooling 1 to climb along the axial direction of the dynamic component 02. The rotating mechanism 12 can drive the supporting mechanism 11 to rotate so that the supporting mechanism 11 and the dynamic component 02 are aligned. The lifting mechanism 13 can drive the supporting mechanism 11 to rise so that the supporting mechanism 11 supports the static component 01, and the supporting mechanism 11 and the static component 01 are connected in the center. The lifting mechanism 13 can also drive the supporting mechanism 11 and the static component 01 to descend synchronously so that the static component 01 and the dynamic component 02 are docked.

[0049] It can be understood that the loading and unloading buffer fixture 1 of the present invention is applicable to any "static to dynamic" docking and disassembly conditions. For example, the loading and unloading buffer fixture 1 of the present invention can be applied to the offshore installation of a self-elevating platform and the operation and maintenance of a floating wind turbine. In this case, the static component 01 is the upper tower, and the dynamic component 02 is the lower tower installed on the floating foundation. The following description is based on the application of the loading and unloading buffer fixture 1 of the present invention to the offshore installation of a self-elevating platform and the operation and maintenance of a floating wind turbine.

[0050] In order to solve the problem of "static against dynamic" when the upper tower and the lower tower are connected due to the shaking of the floating foundation and to avoid damaging the connecting flanges between the unit towers, the present invention proposes a loading and unloading buffer tool 1. When working, the loading and unloading buffer tool 1 is installed on the outer periphery of the lower tower, and the climbing mechanism 14 can make the entire loading and unloading buffer tool 1 move along the outer wall of the lower tower until the loading and unloading buffer tool 1 moves to the top flange of the lower tower; the rotating mechanism 12 can make the upper bearing mechanism 11 rotate to ensure that the bearing mechanism 11 and the lower tower are aligned, so that the upper tower After the tower is aligned and connected with the bearing mechanism 11, the relative position between the upper tower and the lower tower can also be guaranteed to be correct, which is convenient for the subsequent docking and installation of the upper tower and the lower tower; the lifting mechanism 13 can first drive the bearing mechanism 11 to rise by using its lifting function until the bearing mechanism 11 supports the upper tower, so as to realize the rapid centering connection between the bearing mechanism 11 and the upper tower. After the rapid docking, the lifting mechanism 13 uses its lifting function to drive the bearing mechanism 11 and the upper tower to slowly descend until the upper tower and the lower tower are docked, so as to avoid collision and damage between the flanges. After the upper tower and the lower tower are docked, the two can be fixed together by connecting bolts, and the two together form a new lower tower. At this time, the loading and unloading buffer tooling 1 is located in the middle of the lower tower, and the function of the climbing mechanism 14 needs to be used again to move the loading and unloading buffer tooling 1 to the top flange of the lower tower, and the above steps are repeated to carry out the docking work of the new upper tower and the lower tower.

[0051] In addition, the loading and unloading buffer fixture 1 can also be used to replace large components of the floating wind turbine set. Specifically, the loading and unloading buffer fixture 1 uses the climbing function of the climbing mechanism 14 to move to the top flange of the lower tower, and then uses the lifting function of the lifting mechanism 13 to enable the bearing mechanism 11 to support the upper tower. The bearing mechanism 11 and the upper tower are connected in a central manner, and the connecting bolts between the upper tower and the lower tower are removed. The upper tower is first driven to move upward by the lifting mechanism 13, and finally the upper tower is lifted and moved away by the crane to avoid the lower tower from colliding and being damaged by the upper tower flange on the shaking floating foundation due to the slow speed of the crane lifting the upper tower.

[0052] It can be seen that during the docking or disassembly process of the upper tower and the lower tower, the loading and unloading buffer tooling is always located between the upper tower and the lower tower, playing a buffering role to prevent the docking flanges between the unit towers from being damaged by collision.

[0053] In summary, the loading and unloading buffer tooling 1 of the present invention can solve the "static against dynamic" problem encountered when the upper tower and the lower tower are connected or disassembled due to the shaking of the floating foundation, and safely realize the installation and operation and maintenance of large-capacity floating wind turbines at offshore machine sites, ensuring the feasibility of the offshore construction process of large-capacity floating wind turbines; at the same time, the process scheme of installing floating wind turbines at offshore machine sites using the loading and unloading buffer tooling 1 does not require the use of large-sized and large-tonnage dock cranes at the dock, nor does it require the use of dock resources to transform the dock bearing capacity, which can greatly reduce the large-capacity The construction cost of floating wind turbines is reduced. At the same time, when installing floating wind turbines at sea, there is no need to tow the floating foundation and wind turbines as a whole, which greatly reduces the towing cost and the uncertain risks in the towing process, such as typhoon interference, and reduces the transportation risk. In addition, the use of the loading and unloading buffer tooling 1 can also take into account the replacement of large components of floating wind turbines in the later stage, ensuring the feasibility of future deep-sea large-capacity floating wind turbines at sea. There is no need to adopt the existing method of towing the entire unit to the dock for replacement of large components, which greatly reduces the maintenance cost of floating wind turbines.

[0054] At the same time, due to the setting of the climbing mechanism 14, the loading and unloading buffer tool 1 can be moved to the top flange of the lower tower when each section of the tower is docked, that is, the loading and unloading buffer tool 1 is located at the same position of the lower tower when each section of the tower is docked. In this way, the movement trajectory of the lifting mechanism 13 when each section of the tower is docked can also be kept consistent, that is, the lifting mechanism 13 drives the bearing mechanism 11 to rise the same distance each time to achieve rapid centering docking of the bearing mechanism 11 and the upper tower, and the lifting mechanism 13 drives the bearing mechanism 11 and the upper tower to descend the same distance each time to achieve docking of the upper tower and the lower tower. It can be seen that, it is precisely because of the setting of the climbing mechanism 14 that the control principle of the lifting mechanism 13 becomes simpler and less prone to errors.

[0055] It can be understood that after the loading and unloading buffer fixture 1 is docked with the upper tower, and during the period when the upper tower and the lower tower have not yet been fixed together by connecting bolts, the lower tower will sway with the floating foundation, thereby driving the loading and unloading buffer fixture 1 to sway, and the docking surface between the loading and unloading buffer fixture 1 and the upper tower will sometimes have a gap and sometimes not. At this time, the heave compensation fixture between the crane and the upper tower can be used to compensate for the heave of the upper tower, ensuring that the upper tower and the loading and unloading buffer fixture 1 are in a relatively static state, thereby ensuring the stability of the docking between the upper tower and the loading and unloading buffer fixture 1.

[0056] like Figure 1 and Figure 6As shown, in this embodiment, the upper side wall of the bearing mechanism 11 is connected with four pads 15, each pad 15 is provided with two positioning pins 16, and the outer side wall of the static component 01 is connected with four positioning plates 03 at corresponding positions, each positioning plate 03 is provided with two positioning holes 03a, when the bearing mechanism 11 supports the positioning plates 03 of the static component 01, the positioning pins 16 and the positioning holes 03a are assembled and disassembled, the bearing mechanism 11 and the static component 01 are aligned. It can be seen that in this embodiment, the positioning pins 16 and the positioning holes 03a form the centering components of the bearing mechanism 11 and the static component 01.

[0057] In practical applications, it is also feasible to provide the static component 01 with a positioning pin 16 and the supporting mechanism 11 with a positioning hole 03a, and the positioning connection between the static component 01 and the supporting mechanism 11 can also be achieved. At the same time, the number of the positioning pins 16 and the positioning holes 03a is not limited, and there can be at least one positioning pin 16 and the positioning hole 03a.

[0058] In addition, in actual applications, the alignment between the supporting mechanism 11 and the static component 01 is not limited to the above-mentioned positioning pins 16 and positioning holes 03a. For example, a positioning protrusion is provided on the outer peripheral wall of the static component 01, and the supporting mechanism 11 is correspondingly connected with a positioning block, and a positioning groove is formed inside the positioning block. When the supporting mechanism 11 supports the static component 01, the positioning protrusion is inserted into the corresponding positioning groove to achieve the alignment of the supporting mechanism 11 and the static component 01.

[0059] As mentioned above, the rotating mechanism 12 can drive the supporting mechanism 11 to rotate so that the supporting mechanism 11 and the dynamic component 02 are centered. Specifically, the supporting mechanism 11 and the dynamic component 02 can be set with a centering reference line, and a camera is set at the position of the centering reference line of one of the supporting mechanism 11 and the dynamic component 02. The camera is aimed at the other of the supporting mechanism 11 and the dynamic component 02, and the camera captures the picture to determine whether the supporting mechanism 11 and the dynamic component 02 are centered. At the same time, the static component 01 can also be set with a centering reference line. When the positioning pin 16 and the positioning hole 03a are inserted and matched, the centering reference line of the static component 01 and the centering reference line of the supporting mechanism 11 are aligned to ensure the centering connection between the supporting mechanism 11 and the static component 01.

[0060] It can be understood that, in practice, the loading and unloading buffer tooling 1 of the present invention also includes a controller, and the rotating mechanism 12, the lifting mechanism 13 and the climbing mechanism 14 are all electrically connected to the controller, and the controller can control the rotating mechanism 12, the lifting mechanism 13 and the climbing mechanism 14 to start or stop the action according to the aforementioned principle.

[0061] Furthermore, if Figure 1As shown, in the present invention, the rotating mechanism 12 specifically includes a rotating bearing 121, a driving tooth portion 122 and a driving unit 123. The inner ring 1211 of the rotating bearing 121 is connected to the climbing mechanism 14, the outer ring 1212 of the rotating bearing 121 is connected to the lifting mechanism 13, the outer ring 1212 of the rotating bearing 121 is provided with an engaging tooth portion 121a on the outer peripheral wall, the driving tooth portion 122 and the engaging tooth portion 121a are engaged with each other, the output shaft of the driving unit 123 is connected to the driving tooth portion 122, the driving unit 123 can drive the driving tooth portion 122 to rotate, the outer ring 1212 of the rotating bearing 121 forms the aforementioned first transmission portion 12a, and the inner ring 1211 of the rotating bearing 121 forms the aforementioned second transmission portion 12b.

[0062] The driving unit 123 may be a driving motor. When working, the controller may control the driving unit 123 to start, and the output shaft of the driving unit 123 drives the driving tooth portion 122 to rotate synchronously. Under the meshing action of the driving tooth portion 122 and the meshing tooth portion 121a, the driving tooth portion 122 drives the outer ring 1212 of the rotating bearing 121 to rotate, and the outer ring 1212 of the rotating bearing 121 drives the bearing mechanism 11 to rotate through the lifting mechanism 13, so as to realize the centering of the bearing mechanism 11 and the dynamic component 02, which is convenient for the subsequent docking and installation of the static component 01 and the dynamic component 02.

[0063] In this embodiment, the driving tooth portion 122 is a driving gear, and the driving tooth portion 122 and the outer ring 1212 of the rotating bearing 121 are driven by gear meshing. In practical applications, the driving tooth portion 122 can also be a worm, and the driving unit 123 is also a driving motor. The output shaft of the driving motor is coaxially connected to the worm, and the driving motor drives the worm to rotate. Under the meshing action of the worm and the meshing tooth portion 121a, the worm drives the outer ring 1212 of the rotating bearing 121 to rotate.

[0064] In this embodiment, there are two driving teeth 122 and two driving units 123, and the driving teeth 122 and the driving units 123 are connected one by one to form a driving unit. The two driving parts are arranged at both ends of the radial direction of the rotating bearing 121, and the two driving parts form a redundant design with high reliability. In practical applications, there is no limit on the number of driving parts, and the number of driving parts can be at least one. When there are multiple driving parts, there is no limit on the positions of the multiple driving parts, and the multiple driving parts can be distributed along the circumference of the rotating bearing 121.

[0065] As mentioned above, the inner ring 1211 of the rotating bearing 121 is connected to the climbing mechanism 14, and the specific connection method is not limited. For example, the inner ring 1211 of the rotating bearing 121 and the climbing mechanism 14 can be fixed by welding, or fixed by connecting members such as bolts. In this embodiment, the inner ring 1211 of the rotating bearing 121 and the climbing mechanism 14 are fixed by bolts. After the docking work is completed, the bolts can be directly removed, and the rotating bearing 121 and the climbing mechanism 14 can be disassembled, and then the rotating bearing 121 and the climbing mechanism 14 can be removed from the tower respectively, which is convenient for operation.

[0066] like Figure 1 As shown, the outer peripheral wall of the climbing mechanism 14 is connected to a lug plate 17, a bearing is installed inside the lug plate 17, and the output shaft of the drive unit 123 passes through the inside of the bearing and is connected to the gear 22, thereby improving the smoothness of rotation of the output shaft of the drive unit 123. In practice, there is no restriction on the connection method between the output shaft of the drive unit 123 and the gear 22, such as the output shaft of the drive unit 123 and the gear 22 can be fixed by welding, threaded connection, or fixed by a wedge key.

[0067] As mentioned above, the outer ring 1212 of the rotating bearing 121 is connected to the lifting mechanism 13, and the specific connection method is not limited. For example, the outer ring 1212 of the rotating bearing 121 and the lifting mechanism 13 can be fixed by welding, or fixed by connecting members such as bolts. Preferably, bolts are used to facilitate the maintenance and replacement of the lifting mechanism 13.

[0068] It can be understood that the rotating bearing 121 can be a whole bearing or a half bearing. Specifically:

[0069] When the rotating bearing 121 is an integral bearing, during the installation or disassembly process of the loading and unloading buffer tooling 1, the rotating bearing 121 can be slidably installed on the tower from the top of the tower, or detached from the tower;

[0070] When the rotating bearing 121 is a half-type bearing, that is, the rotating bearing 121 includes a first bearing part and a second bearing part, the first bearing part and the second bearing part are butted together in the circumferential direction, and are connected together in a detachable manner, so that during the installation process of the loading and unloading buffer tooling 1, the rotating bearing 121 can be firstly split into a split structure of the first bearing part and the second bearing part, the first bearing part and the second bearing part are circumferentially enveloping the outer wall of the lower tower, and then the first bearing part and the second bearing part are connected together by bolts and other connecting parts to complete the installation of the rotating bearing 121; after the tower butt work is completed, the connecting parts can be detached to directly remove the first bearing part and the second bearing part, and the disassembly of the rotating bearing 121 is completed. It can be seen that it is more convenient to load and unload the rotating bearing 121 using a half-type bearing.

[0071] Please continue to refer to Figure 3 and Figure 8In the present invention, the climbing mechanism 14 includes a guide rail 141 and a climbing unit. The guide rail 141 is provided with pin shaft holes 141a distributed at intervals along the axial direction. The climbing unit includes a traction part 142, a follower part 143, and a telescopic component 144 connecting the traction part 142 and the follower part 143. The telescopic component 144 can be telescopic to drive the traction part 142 and the follower part 143 to be relatively close to or relatively far away from each other. The telescopic distance of the telescopic component 144 is not less than the distance between two adjacent pin shaft holes 141a. The follower part 143 is connected to the second transmission part 12b, that is, the follower part 143 is connected to the inner ring 1211 of the rotating bearing 121. The inner walls of the traction part 142 and the follower part 143 are both provided with a driving member 145 and a pin shaft 146. The output shaft of the driving member 145 is connected to the pin shaft 146. The output shaft of the driving member 145 can be extended or retracted to drive the pin shaft 146 to extend or retract.

[0072] In the installed state, the guide rail 141 is fixed to the outer peripheral walls of the static component 01 and the dynamic component 02, and the guide rail 141 extends along the axial direction of the static component 01 and the dynamic component 02. The traction part 142 and the follower part 143 are both slidably installed on the guide rail 141. The pin shaft 146 can be extended or retracted under the action of the driving member 145 to be inserted into the pin shaft hole 141a, or detached from the pin shaft hole 141a.

[0073] In practice, the driving member 145 and the telescopic member 144 in the traction part 142 and the follower part 143 are electrically connected to the controller. The driving member 145 can be a cylinder / hydraulic cylinder / electric cylinder, etc., and the push rod of the cylinder / hydraulic cylinder / electric cylinder is connected to the pin 146.

[0074] When it is necessary to dock the towers, the loading and unloading buffer tooling 1 needs to climb to the top flange of the tower below, which can be achieved through the climbing function of the climbing mechanism 14, that is, in the initial state, the climbing mechanism 14 is located at the bottom or middle of the lower tower, and the pins 146 in the traction part 142 and the follower part 143 are both inserted into the corresponding pin holes 141a. When the climbing mechanism 14 receives the climbing instruction, the controller first controls the drive member 145 in the follower part 143 to retract, and the drive member 145 drives the corresponding pin 146 to retract, The pin 146 in the follower 143 is disengaged from the corresponding pin hole 141a, releasing the limit between the follower 143 and the guide rail 141; then, the telescopic component 144 extends to move the follower 143 upward along the guide rail 141 to the position of the pin hole 141a adjacent to the upper end, and the extension of the telescopic component 144 stops, and the driving member 145 in the follower 143 is actuated to extend the corresponding pin 146 to the pin hole 141a adjacent to the upper end. At this time, the follower 143 completes a climbing stroke;

[0075] Next, the driving member 145 in the traction part 142 is actuated, the output shaft of the driving member 145 is retracted, and the pin 146 in the traction part 142 is retracted, so that the pin 146 in the traction part 142 is disengaged from the corresponding pin hole 141a, and the limit between the traction part 142 and the guide rail 141 is released; then, the telescopic component 144 moves the traction part 142 upward along the guide rail 141 to the position of the pin hole 141a at the adjacent upper end through the retraction action, and the retraction action of the telescopic component 144 stops, and the driving member 145 in the traction part 142 is actuated to extend the corresponding pin 146 to the pin hole 141a at the adjacent upper end. At this time, the loading and unloading buffer tooling 1 completes a climbing stroke as a whole, and the above actions are repeatedly performed until the loading and unloading buffer tooling 1 reaches the top flange of the lower tower.

[0076] It can be seen that through the setting of the above climbing mechanism 14, the loading and unloading buffer tooling 1 can climb to the top flange of the lower tower each time it is docked, thereby playing a buffering role when the lower tower and the upper tower are docked; at the same time, the setting of the climbing mechanism 14 enables the movement trajectory of the lifting mechanism 13 to remain consistent when each section of the tower is docked, thereby simplifying the control principle of the lifting mechanism 13.

[0077] As can be seen from the foregoing, in this embodiment, the climbing mechanism 14 moves upward by the distance of a pin hole 141a in each climbing stroke. In other words, each climbing stroke of the traction part 142 and the follower part 143 moves from the position of a pin hole 141a to the position of the upper adjacent pin hole 141a. It can be understood that in actual applications, the specific value of each climbing stroke of the climbing mechanism 14 is not limited. For example, the climbing mechanism 14 can also move upward by the distance of two pin holes 141a in each climbing stroke, as long as the distance of each climbing stroke of the climbing mechanism 14 is equal, it is easy to control, and the last climbing stroke of the climbing mechanism 14 can just reach the top flange of the lower tower.

[0078] Depend on Figure 3 It can be seen that in the present embodiment, two driving members 145 are arranged in the traction part 142 and the follower part 143 corresponding to each guide rail 141, the two driving members 145 are arranged opposite to each other, and the two pin shafts 146 are arranged opposite to each other. In the installed state, the two pin shafts 146 are located on both sides of the guide rail 141, and the two pin shafts 146 can be inserted into the same pin shaft hole 141a from the two ends of the pin shaft hole 141a.

[0079] It can be understood that the loading and unloading buffer tooling 1 of the present invention mainly relies on the pin shaft 146 to withstand the shear force of the whole. Each pin shaft hole 141a is inserted and matched with two pin shafts 146. The two pin shafts 146 can withstand the shear force at the same time, thereby improving the installation stability of the loading and unloading buffer tooling 1 and preventing the pin shaft 146 from breaking and failing.

[0080] Depend on Figure 2 It can be seen that in this embodiment, the telescopic component 144 includes four telescopic cylinders, and the outer peripheral walls of the traction part 142 and the follower part 143 are correspondingly provided with four groups of connecting parts 147, and the connecting parts 147 specifically include two oppositely arranged ear plates 17, and the two ends of the telescopic cylinder are respectively hinged through the hinge shaft and the corresponding connecting parts 147. In this way, the traction part 142 and the follower part 143 can be driven to be relatively close to or relatively far away by the extension or retraction of the telescopic cylinder.

[0081] In practical applications, the number of telescopic cylinders included in the telescopic component 144 is not limited, for example, the number of telescopic cylinders included in the telescopic component 144 may be more than two. The telescopic cylinder may be a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, and the like.

[0082] At the same time, the telescopic component 144 is not limited to the structural form of the telescopic cylinder in the present embodiment. For example, the telescopic component 144 can also be a combination of a driving motor and a gear rack transmission unit, or a driving motor and a screw and nut transmission unit. Taking the telescopic component 144 including a driving motor and a gear rack transmission unit as an example, specifically, the gear rack transmission unit includes a gear and a rack that mesh with each other, and the lower end of the rack is fixed to the traction part 142, and the rack extends in a direction approaching or away from the following part 143. The following part 143 is provided with a guide block at a position corresponding to the rack, and a guide hole is provided inside the guide block, and the rack is movably inserted in the guide hole. The driving motor is connected to the following part 143, and the output shaft of the driving motor is connected to the gear. The driving motor can drive the gear to rotate. Under the meshing action of the gear and the rack, the gear can also slide along the axial direction of the rack, thereby realizing the relative approach or relative distance between the traction part 142 and the following part 143.

[0083] As mentioned above, in the installed state, the traction part 142 and the follower part 143 are both slidably installed on the guide rail 141. Specifically in this embodiment, Figure 3 and Figure 8 As shown, the guide rail 141 is provided with a T-shaped guide protrusion 1411, which extends axially along the guide rail 141, and the inner wall of the follower part 143 and the inner wall of the traction part 142 are correspondingly provided with a slider 148, and the slider 148 is provided with a T-shaped guide groove 148a. In the installed state, the guide protrusion 1411 is slidably installed inside the corresponding guide groove 148a.

[0084] Through the cooperation of the above-mentioned guide protrusion 1411 and the guide groove 148a, on the one hand, it can play a circumferential limiting role on the loading and unloading buffer tooling 1 to prevent the loading and unloading buffer tooling 1 from circumferential rotation; on the other hand, it can also play a guiding role on the loading and unloading buffer tooling 1, so that the loading and unloading buffer tooling 1 can only slide along the axial direction of the guide protrusion 1411, thereby ensuring the position accuracy of the loading and unloading buffer tooling 1.

[0085] In this embodiment, after the guide protrusion 1411 is inserted into the guide groove 148a, the two are mutually limited in radial direction. In practical applications, the shapes of the guide protrusion 1411 and the guide groove 148a are not limited, as long as they can achieve the circumferential limiting and guiding functions, and the radial unlimited relationship is also feasible, such as the guide protrusion 1411 and the guide groove 148a can also be matched strips.

[0086] In this embodiment, the guide protrusion 1411 is arranged on the guide rail 141 , and the guide groove 148 a is arranged on the slider 148 . In practical applications, it is also feasible to arrange the guide groove 148 a on the guide rail 141 and the guide protrusion 1411 on the slider 148 .

[0087] In this embodiment, there are four guide rails 141, and the four guide rails 141 are distributed along the circumference of the tower. In practical applications, there is no restriction on the number of guide rails 141, for example, the number of guide rails 141 can be at least one.

[0088] In this embodiment, the slider 148 adopts an existing deformable square slider, that is, the clamping parts at both ends of the slider 148 can be forced to spring away from each other, so that the slider 148 and the guide protrusion 1411 are separated from each other. The specific structure and deformation principle of the square slider are well known to those skilled in the art, and will not be repeated here.

[0089] Further, by Figure 1-Figure 5 It can be seen that in this embodiment, the traction part 142 and the follower part 143 each include four split parts, which are distributed along the circumferential direction and connected in sequence to form a circle. A slider 148 is provided inside each split part for plugging and cooperating with the guide rail 141, and two adjacent split parts are fixedly connected by fixing bolts.

[0090] In this embodiment, the traction part 142 and the following part 143 are arranged as split structures along the circumferential direction, and the two adjacent split parts are fixedly connected by fixing bolts. During the installation process of the loading and unloading buffer tooling 1, the fixing bolts can be removed first, and the traction part 142 and the following part 143 can be separated into a structure of four split parts. The four split parts envelop the outer wall of the lower tower along the circumferential direction, and the slider 148 and a guide rail 141 in each split part are inserted and matched. Finally, the two adjacent split parts are connected together by fixing bolts to complete the installation of the climbing mechanism 14; after the tower docking work is completed, the fixing bolts can be removed again, and then the slider 148 in each split part is controlled to deform, and the radial limiting relationship between the slider 148 and the guide rail 141 is released. At this time, each split part can be directly removed to complete the disassembly of the climbing mechanism 14.

[0091] It can be seen that as above, the traction part 142 and the follower part 143 are arranged as a split structure along the circumferential direction, and there is no need to adopt the installation method of the climbing mechanism 14 being installed on the tower from the top of the tower, or the disassembly method of being detached from the tower from the top of the tower, which makes the disassembly and assembly of the climbing mechanism 14 more convenient and improves work efficiency.

[0092] Depend on Figure 1 It can be seen that in this embodiment, the number of telescopic parts 144 is four, and the number of guide rails 141 is four, so the traction part 142 and the follower part 143 are split into four parts, and the corresponding parts are connected together through the telescopic parts 144. The corresponding parts can be disassembled and assembled at the same time, and a slider 148 is set on the inner wall of each part. In this way, when one of the telescopic parts 44 fails, there is no need to disassemble the climbing mechanism 14 as a whole, and only the corresponding part needs to be disassembled to repair and replace the corresponding telescopic part, which greatly reduces the maintenance workload and improves work efficiency.

[0093] In practical applications, there is no limitation on the structure of the traction part 142 and the following part 143 . For example, the traction part 142 and the following part 143 can be split into at least two separate parts. Preferably, the number of separate parts of the traction part 142 and the following part 143 is consistent with the number of the telescopic parts 144 .

[0094] In addition, by Figure 2 It can be seen that two adjacent sub-parts are provided with folded edges protruding radially outward, and the folded edges of the two adjacent sub-parts fit each other and are fixed together by fixing bolts. In practical applications, there is no restriction on the connection method of the two adjacent sub-parts, such as the two adjacent sub-parts can also be fixed by a detachable method such as snap connection.

[0095] Furthermore, if Figure 2 and Figure 8 As shown, in the present invention, the guide rail 141 is also provided with reference holes 141b distributed at intervals along the axial direction, the reference holes 141b and the pin shaft holes 141a correspond one to one, and the inner walls of the traction part 142 and the follower part 143 are both provided with centering sensors 149. When the centering sensor 149 detects the position of the reference hole 141b, the pin shaft 146 is opposite to the pin shaft hole 141a.

[0096] In this way, during the climbing process of the traction part 142 and the following part 143, the centering sensor 149 will continue to detect the position of the reference hole 141b. When the centering sensor 149 detects the position of the reference hole 141b for the first time, it indicates that the traction part 142 or the following part 143 has completed a climbing stroke. At this time, the controller will control the telescopic part 144 to stop moving, and control the driving part 145 of the traction part 142 or the following part 143 to move, and extend the corresponding pin shaft 146 to the inside of the pin shaft hole 141a.

[0097] It can be seen that, by providing the reference hole 141 b and the centering sensor 149 , the climbing stroke of the traction part 142 and the follower part 143 can be accurately controlled, thereby improving the movement accuracy of the traction part 142 and the follower part 143 .

[0098] In practice, the centering sensor 149 is also electrically connected to the controller. The specific structure and detection principle of the centering sensor 149 are well known to those skilled in the art and will not be described in detail herein.

[0099] Depend on Figure 1 and Figure 2 It can be seen that in this embodiment, the inner walls of the traction part 142 and the follower part 143 are designed with L-shaped brackets 140 on both sides of each slider 148, wherein at least one L-shaped bracket 140 is connected to a centering sensor 149 for detecting the position of the reference hole 141b, and the inner walls of the traction part 142 and the follower part 143 are also designed with ear plates 17 on both sides of each slider 148, the driving member 145 is fixed to the ear plate 17, and the pin shaft 146 passes through the ear plate 17 and the L-shaped bracket 140 in sequence and is inserted into the pin shaft hole 141a of the guide rail 141.

[0100] Please continue to refer to Figure 1-Figure 5 In this embodiment, the lifting mechanism 13 includes a driving part 131 and a plurality of screw-nut transmission units 132. The driving part 131 and the plurality of screw-nut transmission units 132 are distributed along the circumference of the first transmission part 12a, that is, distributed along the circumference of the outer ring 1212 of the rotating bearing 121. The screw-nut transmission unit 132 includes a screw rod 1321 and a nut connected by threads. The lower end of the screw rod 1321 is rotatably connected to the first transmission part 12a, and the nut is connected to the bearing mechanism 11. The driving part 131 is connected to the first transmission part 12a, and the output shaft of the driving part 131 is rotatably passed through the bearing mechanism 11.

[0101] It also includes a driving gear 133 and multiple driven gears 134. The driving gear 133 is connected to the output shaft of the driving unit 131. The driving unit 131 can drive the driving gear 133 to rotate. The driven gears 134 are connected to the upper ends of the screw rods 1321 one by one. The driving gear 133 and the multiple driven gears 134 are connected through a belt 135.

[0102] In practice, the driving part 131 may be a driving motor. When working, the output shaft of the driving part 131 can drive the driving gear 133 to rotate through the action of the driving part 131, and the driving gear 133 drives each driven gear 134 to rotate through the belt 135, and the driven gear 134 can make the corresponding screw rod 1321 rotate, and under the thread cooperation between the screw rod 1321 and the nut, the corresponding nut can move along the axial direction of the screw rod 1321, thereby realizing the lifting and lowering of the bearing mechanism 11.

[0103] In this embodiment, the belt 135 is an internally toothed belt, and the belt 135 and the driving gear 133, and the belt 135 and the driven gear 134 are all meshed through teeth, so the transmission is reliable.

[0104] In practice, the lifting mechanism 13 is not limited to the above implementation. For example, the lifting mechanism 13 includes multiple driving parts, which are distributed along the circumference of the first transmission part 12a. The driving parts are connected to the first transmission part 12a. The output shaft of the driving part is connected to the support mechanism 11. The output shaft of the driving part can be extended or retracted to achieve the lifting of the support mechanism 11. The driving part can be a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, etc. It can be seen that this implementation method realizes the lifting of the support mechanism 11 through multiple power sources, while the present invention realizes the lifting of the support mechanism 11 through a single power source and mechanical transmission, which has reliable transmission and low cost, and is a more preferred technical solution.

[0105] As mentioned above, the lower end of the screw rod 1321 is rotatably connected to the first transmission part 12a, and the driving part 131 is connected to the first transmission part 12a, specifically, a direct connection method or an indirect connection method can be adopted. This embodiment adopts an indirect connection method, specifically, Figure 1 As shown, the lifting mechanism 13 also includes an annular base 136, which is fixed to the first transmission part 12a. The specific fixing method is not limited, such as welding or bolts. Bolts are preferably used to facilitate the disassembly and assembly of the lifting mechanism 13 and the rotating mechanism 12. The lower end of the screw rod 1321 is rotatably connected to the annular base 136, and then connected to the first transmission part 12a at intervals. The driving part 131 is connected to the annular base 136, and then connected to the first transmission part 12a at intervals.

[0106] Furthermore, if Figure 1 As shown, the lower end of the screw rod 1321 is rotatably connected to the annular base 136 through a connecting seat 137, and the connecting seat 137 is fixed to the upper side wall of the annular base 136 by bolts. A bearing is installed inside the connecting seat 137, and the lower end of the screw rod 1321 is installed on the connecting seat 137 through the bearing, so that the rotation of the screw rod 1321 is smoother.

[0107] In practice, there is no limitation on the fixing method of the connecting seat 137 and the annular base 136 . For example, it is also feasible to fix the connecting seat 137 and the annular base 136 by welding.

[0108] In this embodiment, the driving part 131 is fixed to the annular base 136 by bolts. In practice, there is no limitation on the fixing method of the driving part 131 and the annular base 136. For example, the driving part 131 and the annular base 136 may be fixed by welding.

[0109] In addition, in this embodiment, the supporting mechanism 11 and the lifting mechanism 13 are also split structures, including two split parts, the corresponding two split parts are distributed along the circumferential direction and connected in sequence to form a circle, and the corresponding ends of the two split parts are detachably connected.

[0110] Among them, the corresponding ends of the two split parts can be connected specifically by fixing bolts. For example, the corresponding ends of the two split parts are both provided with folded edges folded outward, and the corresponding folded edges are provided with connecting holes. The fixing bolts pass through the corresponding connecting holes to fix the corresponding folded edges together, thereby realizing the fixed connection of the two split parts.

[0111] In this way, during the installation of the loading and unloading buffer tooling 1, the fixing bolts can be removed first, and the bearing mechanism 11 and the annular base 136 can be separated into a structure of two separate parts. The corresponding two separate parts can be circumferentially connected to the outer wall of the enveloping dynamic component 02, and then the corresponding two separate parts can be connected together through the fixing bolts to complete the installation of the bearing mechanism 11 and the lifting mechanism 13; after the tower docking work is completed, the fixing bolts can be removed again, and the two separate parts can be directly removed to complete the disassembly of the bearing mechanism 11 and the lifting mechanism 13.

[0112] It can be seen that the bearing mechanism 11 and the lifting mechanism 13 are arranged as a circumferentially separated structure, and during the loading and unloading process, there is no need to set the top of the dynamic component 02, which is convenient for operation and improves work efficiency.

[0113] In practice, there is no limitation on the connection method of the two parts, such as fixing by snap connection, etc. In practice, there is no limitation on the structure of the supporting mechanism 11, such as the supporting mechanism 11 can be split into more than three parts.

[0114] The overall working process of the loading and unloading buffer tool 1 in this embodiment when the dynamic component 02 and the static component 01 are docked is as follows:

[0115] In the initial state, the climbing mechanism 14 is located at the bottom or middle of the dynamic component 02, and the pins 146 in the traction part 142 and the follower part 143 are inserted into the corresponding pin holes 141a. After the climbing mechanism 14 receives the climbing command, the driving member 145 in the follower part 143 is retracted, and the corresponding pin 146 is retracted to disengage from the corresponding pin hole 141a, and the limit of the follower part 143 and the guide rail 141 is released. The telescopic component 144 pushes the follower part 143 to move upward along the guide rail 141 through the extension action. When the centering sensor 149 in the follower part 143 detects the position of the next reference hole 141b, the extension action of the telescopic component 144 stops, and the driving member 145 in the follower part 143 is actuated, and the corresponding pin 146 is extended. The drive member 145 in the traction part 142 is actuated to drive the corresponding pin 146 to be retracted to disengage from the corresponding pin hole 141a, thereby releasing the position limit of the traction part 142 and the guide rail 141. The telescopic member 144 moves the traction part 142 upward along the guide rail 141 by the retraction action. When the centering sensor 149 of the traction part 142 detects the position of the next reference hole 141b, the retraction action of the telescopic member 144 stops, and the drive member 145 in the traction part 142 is actuated to drive the corresponding pin 146 to extend out and be inserted into the next pin hole 141a. At this time, a climbing stroke is completed, and the above actions are repeated until the loading and unloading buffer tooling 1 reaches the top flange of the dynamic component 02.

[0116] Then, the driving unit 123 of the rotating mechanism 12 is started, and the output shaft of the driving unit 123 drives the driving tooth portion 122 to rotate synchronously. Under the meshing action of the driving tooth portion 122 and the meshing tooth portion 121a, the driving tooth portion 122 drives the outer ring 1212 of the rotating bearing 121 to rotate, and the outer ring 1212 of the rotating bearing 121 drives the supporting mechanism 11 to rotate through the lifting mechanism 13, so as to realize the alignment of the supporting mechanism 11 and the dynamic component 02;

[0117] Next, the driving part 131 in the lifting mechanism 13 is activated, and the output shaft of the driving part 131 drives the driving gear 133 to rotate, and the driving gear 133 drives each driven gear 134 to rotate through the belt 135, and the driven gear 134 causes the corresponding screw rod 1321 to rotate. Under the threaded cooperation between the screw rod 1321 and the nut, the corresponding nut moves upward along the axial direction of the screw rod 1321, thereby realizing the lifting of the bearing mechanism 11, until the bearing mechanism 11 supports the static component 01, the positioning pin 16 and the positioning hole 03a are correspondingly inserted and matched, and the bearing mechanism 11 and the static component 01 are connected in a centering manner;

[0118] Finally, the driving part 131 in the lifting mechanism 13 moves in the reverse direction, and the output shaft of the driving part 131 drives the driving gear 133 to rotate in the reverse direction, and the driving gear 133 drives each driven gear 134 to rotate in the reverse direction through the belt 135, and the driven gear 134 causes the corresponding screw rod 1321 to rotate in the reverse direction. Under the thread cooperation of the screw rod 1321 and the nut, the corresponding nut moves downward along the axial direction of the screw rod 1321, driving the bearing mechanism 11 and the static component 01 to fall synchronously until the flanges of the static component 01 and the dynamic component 02 are docked.

[0119] In this embodiment, the loading and unloading buffer tool 1 can be installed on the dynamic component 02 (lower tower) in two ways, specifically:

[0120] In the first installation method, the loading and unloading buffer tool 1 is integrally slidably installed on the dynamic component 02 from the top of the dynamic component 02.

[0121] In the second installation method, the loading and unloading buffer tooling 1 is divided into independent structures of the rotating mechanism 12, the lifting mechanism 13 and the climbing mechanism 14, and the three parts are installed separately. The specific installation steps are as follows:

[0122] First, the traction part 142 and the follower part 143 are separated into four separate parts, and the four separate parts envelop the outer wall of the lower tower in the circumferential direction. The slider 148 in each separate part is inserted and matched with a guide rail 141, and then the two adjacent separate parts are connected together by fixing bolts to complete the installation of the climbing mechanism 14;

[0123] Secondly, the rotating bearing 121 is split into a first bearing part and a second bearing part, the first bearing part and the second bearing part circumferentially envelop the outer wall of the lower tower, and then the first bearing part and the second bearing part are connected together by bolts and other connecting parts to complete the installation of the rotating bearing 121, and the follower 143 and the inner ring 1211 of the rotating bearing 121 are connected;

[0124] Then, the bearing mechanism 11 and the lifting mechanism 13 are separated into two separate structures. The two separate parts can be connected to the outer wall of the dynamic component 02 along the circumferential direction, and then the two separate parts are connected together by fixing bolts to complete the installation of the bearing mechanism 11. Then, the annular base 136 in the lifting mechanism 13 is connected to the outer ring 1212 of the rotating bearing 121 by fixing bolts to complete the installation of the loading and unloading buffer tooling 1.

[0125] In this embodiment, the loading and unloading buffer tool 1 is detached from the dynamic component 02 (lower tower), and two installation methods can also be adopted, specifically:

[0126] In the first installation method, the loading and unloading buffer tool 1 as a whole slides from the top of the dynamic component 02 and detaches from the dynamic component 02;

[0127] In the second installation method, the loading and unloading buffer tooling 1 is split into separate structures of the rotating mechanism 12, the lifting mechanism 13 and the climbing mechanism 14, and the three parts are further split into separate structures along the circumferential direction, so that they can be separated from the dynamic component 02.

[0128] The present invention also provides a static-to-dynamic docking method, based on the aforementioned loading and unloading buffer tool 1, comprising the following steps:

[0129] The climbing mechanism 14 climbs along the axial direction of the dynamic component 02 until the loading and unloading buffer tooling 1 moves to the top flange of the dynamic component 02, the rotating mechanism 12 drives the bearing mechanism 11 to rotate, so that the bearing mechanism 11 and the dynamic component 02 are aligned, the lifting mechanism 13 drives the bearing mechanism 11 to rise until the bearing mechanism 11 supports the static component 01, and the bearing mechanism 11 and the static component 01 are connected in an aligned manner, the lifting mechanism 13 drives the bearing mechanism 11 and the static component 01 to descend until the flanges of the static component 01 and the dynamic component 02 are docked.

[0130] The static-to-dynamic docking method of the present invention is based on the aforementioned loading and unloading buffer tooling 1, and therefore has the same technical effects as the aforementioned loading and unloading buffer tooling 1, which will not be described in detail herein.

[0131] Further, as mentioned above, the climbing mechanism 14 climbs along the axial direction of the dynamic component 02 until the loading and unloading buffer tooling 1 moves to the top flange of the dynamic component 02, which specifically includes the following steps:

[0132] In the initial state, the climbing mechanism 14 is located at the bottom or middle of the dynamic component 02, and the pins 146 in the traction part 142 and the follower part 143 are inserted into the corresponding pin holes 141a. When the climbing mechanism 14 receives a climbing instruction, the driving member 145 in the follower part 143 drives the corresponding pin 146 to be retracted and disengaged from the corresponding pin hole 141a. The telescopic component 144 moves the follower part 143 upward along the guide rail 141 to the position of the pin hole 141a adjacent to the upper end through an extension action. The extension action of the telescopic component 144 stops, and the driving member 145 in the follower part 143 drives the corresponding pin 146 to extend and be inserted into the pin hole 141a adjacent to the upper end.

[0133] The driving member 145 in the traction part 142 drives the corresponding pin shaft 146 to be retracted and disengaged from the corresponding pin shaft hole 141a. The telescopic member 144 moves the traction part 142 upward along the guide rail 141 to the position of the pin shaft hole 141a adjacent to the upper end through the retraction action. The retraction action of the telescopic member 144 stops, and the driving member 145 in the traction part 142 drives the corresponding pin shaft 146 to extend and be inserted into the pin shaft hole 141a adjacent to the upper end.

[0134] Repeat the above steps until the loading and unloading buffer tooling 1 reaches the top flange of the dynamic component 02.

[0135] Further, as mentioned above, the guide rail 141 is provided with reference holes 141b distributed at intervals along the axial direction, the reference holes 141b and the pin holes 141a are provided in one-to-one correspondence, and the inner walls of the traction part 142 and the follower part 143 are both provided with centering sensors 149; therefore,

[0136] In the process of the telescopic member 144 moving the follower 143 upward along the guide rail 141 by extending, when the centering sensor 149 detects the position of the reference hole 141b, the follower 143 moves to the position of the pin hole 141a adjacent to the upper end;

[0137] When the telescopic member 144 moves the traction portion 142 upward along the guide rail 141 through the retraction action, when the centering sensor 149 detects the position of the reference hole 141 b , the traction portion 142 moves to the position of the pin hole 141 a adjacent to the upper end.

[0138] Therefore, by setting the reference hole 141 b and the centering sensor 149 , the climbing stroke of the traction part 142 and the follower part 143 can be accurately controlled, thereby improving the movement accuracy of the traction part 142 and the follower part 143 .

[0139] The present invention also provides a static-to-dynamic disassembly method, based on the aforementioned loading and unloading buffer tool 1, comprising the following steps:

[0140] The climbing mechanism 14 climbs along the axial direction of the dynamic component 02 until the loading and unloading buffer tooling 1 moves to the top flange of the dynamic component 02. The lifting mechanism 13 drives the bearing mechanism 11 to rise until the bearing mechanism 11 supports the static component 01, and the bearing mechanism 11 and the static component 01 are connected in a centering manner. The connecting bolts between the dynamic component 02 and the static component 01 are removed, and the static component 02 is driven to move upward by the lifting mechanism 13 until the crane lifts and removes the static component 01.

[0141] The static-to-dynamic disassembly method of the present invention is based on the aforementioned loading and unloading buffer tooling, and therefore has the same technical effects as the aforementioned loading and unloading buffer tooling, which will not be described in detail herein.

[0142] At the same time, the loading and unloading buffer tooling is always located between the dynamic component 02 and the static component 01 to prevent the dynamic component 02 from colliding and being damaged by the static component 01 due to the slow speed of the crane lifting the static component 01.

[0143] The above is a detailed introduction to a loading and unloading buffer tooling, a static-to-dynamic docking method, and a static-to-dynamic disassembly method provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
