Description

Technical Field

[0001] The present invention relates to the technical field of wind power flange installation, and more particularly to an auxiliary tool for installing a segmented wind power flange and a method for using the tool. Background Art

[0002] Due to the remote location and complex terrain of wind power projects, the transportation of large-diameter towers is not feasible. To address this transportation challenge, the wind turbine tower is prefabricated in sections, then split into three pieces for stacked transportation. Once the sections arrive on site, they are connected at the flanges with high-strength bolts to ensure structural strength equivalent to that of a monolithic tower.

[0003] The longitudinal flange of a segmented tower is generally about 15 to 30 meters long. It is large in size and too heavy. During the on-site splicing process, operators are required to perform multiple hoisting and splicing operations, resulting in low installation efficiency.

[0004] In order to improve the on-site installation efficiency of the longitudinal flange of the segmented tower, segmented tower installation auxiliary support devices have appeared on the market, such as a segmented tower installation auxiliary support device with publication number CN115559858A. This invention adjusts the arc curvature radius of the outer wall of the arc-shaped elastic support plate, so that auxiliary support for tower segments of different heights can be achieved without replacing the arc-shaped elastic support plates with different curvature radii, thereby reducing the operation difficulty and production cost of the equipment.

[0005] However, the device can only support a single segmented wind turbine flange tower at a time, and after support, it needs to be aligned through the device. The overall operation process is unstable, prone to docking misalignment, and has low efficiency.

[0016] A further technical solution of the present application is as follows: the shielding portion specifically includes a shielding block and an auxiliary exit mechanism provided inside the shielding block, and the plug-in block is connected to the outside of the shielding block, the side of the shielding block away from the plug-in block is an inclined surface, and when the two shielding blocks are brought together and closed, the inclined surfaces abut against each other and squeeze out;

[0017] The auxiliary exit mechanism specifically includes a spring groove opened on the inner side of the blocking block, an abutment spring connected to the inside of the spring groove at one end, and a retraction frame connected to the other end of the abutment spring.

[0037] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. The present invention is further described below in conjunction with the embodiments.

[0038] See also Figures 1 to 6 In one embodiment of the present application, an auxiliary tool for installing a segmented wind turbine flange includes a first support assembly 1 and a second support assembly 2 that are parallel to each other and aligned at both ends. The first support assembly 1 and the second support assembly 2 cooperate with each other to support two segmented wind turbine flanges.

[0039] The second support assembly 2 includes a base 13 and a drive unit installed in the base 13. Two support mechanisms 4 are symmetrically installed on the drive unit. A single support mechanism 4 is used to support one end of the segmented wind turbine flange. The two support mechanisms 4 are driven by the drive unit to move closer together and bring the ends of the segmented wind turbine flange on the same side closer together.

[0040] A shielding portion 5 is further provided on a single support mechanism 4, and the shielding portion 5 is used to support the side end face of the segmented wind turbine flange, and the two shielding portions 5 inside the two support mechanisms 4 are arranged in a mirror-symmetrical manner. The two support mechanisms 4 are brought closer to each other until the two shielding portions 5 are squeezed out to achieve splicing;

[0041] The first support assembly 1 and the second support assembly 2 have the same structure.

[0042] This embodiment is achieved as follows: the first support assembly 1 and the second support assembly 2 are placed parallel to each other and aligned at both ends, and the support mechanisms 4 inside the two support members support the two sliced ​​wind turbine flanges. During the support process, the shielding portion 5 provided on the side of the support mechanism 4 can shield the two sliced ​​wind turbine flanges to ensure that the two sliced ​​wind turbine flanges will not become loose. On this basis, the driving portion inside the first support assembly 1 and the second support assembly 2 will synchronously bring the support mechanism 4 and the two sliced ​​wind turbine flanges together to quickly fit and fix the two sliced ​​wind turbine flanges. Among them, the main function of the shielding portion 5 is to ensure that the support mechanism 4 can stably block and limit the sliced ​​wind turbine flange supported above it to prevent the bearing During the process of carrying the segmented wind turbine flange and bringing the segmented wind turbine flange together, looseness occurs. However, if a manually disassembled shielding mechanism is set, it needs to be taken out manually, and when the two shielding parts 5 are squeezed and contacted, there will be resistance when manually taking out the shielding mechanism, which is inconvenient to operate. Even if the shielding mechanism is taken out, the segmented wind turbine flange may become loose or even fall off. Therefore, a shielding part 5 that can be automatically retracted is set. The shielding part 5 can be automatically squeezed out and can be taken out without manual assistance. On the one hand, the inconvenience of manual operation is eliminated. On the other hand, the shielding part 5 will not be significantly loosened or shaken when it is taken out, ensuring that the driving part can drive the two supporting mechanisms 4 and the two segmented wind turbine flanges to be completely fitted, and the efficiency is further improved.

[0043] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As a preferred embodiment of the present application, the driving part includes an inner cavity 12 opened in the base 13 and a screw groove 15 opened at the bottom of the inner cavity 12. A driving motor 10 is installed on the outside of the base 13. The power output shaft of the driving motor 10 extends into the screw groove 15 and is connected to one end of the second screw 8. The other end of the second screw 8 is connected to one end of the first screw 9. The outer sides of the first screw 9 and the second screw 8 are both threadedly connected with a screw sleeve 19, and the support mechanism 4 is installed on the screw sleeve 19 and slides inside the inner cavity 12.

[0044] The first screw 9 and the second screw 8 have the same length, and the outer threads thereof are in opposite directions.

[0045] Furthermore, a plurality of fixing seats 3 are provided outside the base 13 , and a fixing hole 11 is provided in each fixing seat 3 .

[0046] This embodiment is implemented as follows: the main function of the driving mechanism is to adjust the respective supporting mechanisms 4 to move closer together, and simultaneously move the segmented wind turbine flanges carried by the supporting mechanisms 4 closer together, so that the end faces of the two segmented wind turbine flanges can be quickly closed and thus quickly fixed;

[0047] Specifically, the first screw 9 and the second screw 8 are driven to rotate by the driving motor 10. During the rotation of the two, the screw sleeve 19 connected to the outside is driven to rotate. Since the screw sleeve 19 is connected to the support mechanism 4, and the support mechanism 4 slides inside the inner cavity 12, the rotation of the screw sleeve 19 is restricted, so that the two screw sleeves 19 will be displaced on the outside of the screws to which they are respectively connected. At the same time, because the first screw 9 and the second screw 8 have the same length and the outer thread directions are opposite, the two screw sleeves 19 drive the support mechanisms 4 to which they are respectively connected to move closer to or away from each other, thereby realizing the closing of the segmented wind power flange.

[0048] In order to prevent the second support assembly 2 from being displaced when carrying the segmented wind turbine flange, the second support assembly 2 can be fixed by a plurality of fixing seats 3 to make its operation more stable.

[0049] It should be noted that how to ensure that the driving mechanisms inside the first support assembly 1 and the second support assembly 2 can operate synchronously can be achieved by using an external controller to control the synchronous operation of the two driving motors 10. This is a mature technology and will not be elaborated on here.

[0050] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As a preferred embodiment of the present application, the support mechanism 4 includes a connecting portion 22 and a supporting portion 20 installed on the connecting portion 22. The supporting portion 20 is used to support the segmented wind turbine flange. The lower end of the connecting portion 22 is connected to the upper end of the driving portion. A connecting mechanism is provided on the side of the connecting portion 22, and the lower end of the shielding portion 5 is connected to the side of the connecting portion 22 through the connecting mechanism. The end faces of the connecting portion 22 and the driving portion in contact with the shielding portion 5 remain vertical.

[0051] Furthermore, the connecting mechanism includes a plug-in slot opened inside the connecting part 22, and abutment slots 25 are symmetrically opened on the upper and lower sides of the plug-in slot. A plug-in block 7 is plugged into the plug-in slot, and abutment strips are provided on the upper and lower sides of the plug-in block 7 corresponding to the abutment slots 25, and the plug-in block 7 is connected to the side of the shielding part 5.

[0052] Furthermore, the shielding portion 5 specifically includes a shielding block 16 and an auxiliary exit mechanism provided inside the shielding block 16, and the plug-in block 7 is connected to the outside of the shielding block 16. The side of the shielding block 16 away from the plug-in block 7 is an inclined surface, and when the two shielding blocks 16 are closed together, the inclined surfaces are in contact with each other and squeezed out;

[0053] The auxiliary exit mechanism specifically includes a spring groove 17 opened on the inner side of the blocking block 16, an abutment spring 18 connected to the inside of the spring groove 17 at one end, and a retraction frame 23 connected to the other end of the abutment spring 18. A number of exit wheels 24 are rotatably arranged inside the retraction frame 23, and when the side end face of the segmented wind turbine flange is above the support part 20, the exit wheel 24 contacts the side end face of the segmented wind turbine flange.

[0054] Furthermore, exit slots 6 are provided on both sides of the middle section of the driving portion. The exit slots 6 are tilted from top to bottom, and the two blocking blocks 16 slide out from the inside of the exit slots 6 when they are brought close together and squeezed out.

[0055] Furthermore, there are multiple auxiliary exit agencies.

[0056] Furthermore, stabilizing blocks 21 are symmetrically provided on both sides of the lower end of the connecting portion 22 , and a stabilizing groove 14 is provided in the driving portion to cooperate with the stabilizing blocks 21 .

[0057] This embodiment is implemented as follows: the two ends of the segmented wind turbine flange are supported by the support mechanism 4. At the same time, during the support process, the end face of the segmented wind turbine flange is blocked by the shielding part 5 to prevent the segmented wind turbine flange from slipping. Because the shielding part 5 needs to automatically fall off after being fitted together, how to ensure this technical effect while ensuring that the shielding part 5 can bear the weight of the segmented wind turbine flange when installed on the side of the support mechanism 4 is a practical problem that needs to be solved.

[0058] The present application adopts a special structure of a connecting mechanism in conjunction with the shielding part 5 to solve this problem. Specifically, the connecting mechanism is set to a plug-in block 7 that cooperates with the plug-in slot for plugging, so that the plug-in block 7 can be withdrawn from the side and the plug-in block 7 is connected to the shielding part 5. At the same time, in order to ensure that the plug-in block 7 will not be separated from the plug-in slot when the shielding part 5 resists the end face of the segmented wind power flange, an abutment groove 25 is also provided inside the plug-in slot, which is used in conjunction with the abutment strips provided on the upper and lower sides of the plug-in block 7. The abutment strips are in contact with the abutment groove 25 to achieve an inward buckle effect, thereby ensuring that the plug-in block 7 and the shielding part 5 can be withdrawn from the side, and also ensuring that the shielding part 5 can bear the weight of the segmented wind power flange.

[0059] At the same time, the shielding part 5 is specifically used in conjunction with the shielding block 16 and the auxiliary exit mechanism to achieve an automatic exit effect. Specifically, the side of the shielding block 16 is set as a slope. Such a setting can ensure that when the two mirror-symmetrical shielding blocks 16 are fitted, the slopes contact first, and the two shielding blocks 16 squeeze each other, thereby achieving the effect of the two shielding blocks 16 pushing each other out, thereby achieving the effect of automatic shielding block 16.

[0060] In addition, in order to prevent the two blocking blocks 16 from being unable to move due to the weight applied to them by the segmented wind turbine flange during the process of squeezing and exiting, an auxiliary exit mechanism is also provided. It is mainly installed inside the spring groove 17 by cooperating with the abutting spring 18 through the retraction frame 23. An exit wheel 24 is provided in the retraction frame 23, and the exit wheel 24 contacts the end face of the segmented wind turbine flange. During the exit process, the exit wheel 24 assists in rotation to reduce friction, thereby quickly exiting the blocking block 16. At the same time, the number of auxiliary exit mechanisms can be set to multiple to ensure stable exit.

[0061] At the same time, exit grooves 6 can be set on both sides of the middle position of the driving part. The exit grooves 6 are set tilted from top to bottom, and when the two blocking blocks 16 are close to each other and squeezed out, they slide out from the inside of the exit grooves 6, so that the blocking blocks 16 can be taken out quickly.

[0062] One thing that needs to be explained is that, in order to increase the stability of the support mechanism 4 during movement, a stabilizing groove 14 can also be provided inside the inner cavity 12, and used in conjunction with the stabilizing block 21 provided under the connecting portion 22 to ensure that the connecting portion 22 is always in a stable sliding state during the movement of the entire support mechanism 4.

[0063] The specific shape of the support portion 20 can be adjusted according to actual conditions, as long as it can meet the needs of supporting the segmented wind turbine flange.

[0064] See also Figures 1 to 6 The method for using the auxiliary tooling for installing the segmented wind turbine flange of the present invention comprises the following steps:

[0065] Step 1: Install the first support assembly 1 and the second support assembly 2, align their ends, and secure them to ensure they are parallel to each other.

[0066] Step 2: Place the two segmented wind turbine flanges symmetrically, lift them up with external lifting equipment, and move them above the first support assembly 1 and the second support assembly 2. Ensure that the outer annular surfaces at both ends of the two segmented wind turbine flanges can contact their respective supporting mechanisms 4. Then cut the materials so that the four supporting mechanisms 4 support the two segmented wind turbine flanges. During the supporting process, the shielding part 5 supports the side end faces of the segmented wind turbine flanges.

[0067] Step three: The internal driving parts of the first support assembly 1 and the second support assembly 2 are operated to drive the connected support mechanisms 4 to move closer to each other, and simultaneously drive the two ends of the two segmented wind turbine flanges to move closer. During the moving closer process, the shielding parts 5 on the side of the support mechanism 4 are contacted and closed in advance. After closing, the driving part continues to work, and the two shielding parts 5 that are in contact with each other are pressed together. Finally, the two shielding parts 5 are squeezed out, so that the lower end faces of the two segmented wind turbine flanges are pressed together, and then the lower end faces of the two segmented wind turbine flanges are connected and fixed.

[0068] To sum up, the present invention sets a first support component 1 and a second support component 2. When in use, the first support component 1 and the second support component 2 are placed parallel to each other and aligned at both ends, and the support mechanisms 4 inside the two support components support the two segmented wind turbine flanges. During the support process, the shielding portion 5 set on the side of the support mechanism 4 can shield the two segmented wind turbine flanges to ensure that the two segmented wind turbine flanges will not loosen. On this basis, the driving portion inside the first support component 1 and the second support component 2 will synchronously bring the support mechanism 4 and the two segmented wind turbine flanges together to quickly fit and fix the two segmented wind turbine flanges, greatly improving the installation efficiency. The main function of the shielding portion 5 is to ensure that the support mechanism 4 can stably block and limit the segmented wind turbine flange supported above it to prevent loosening during the approach process, and the shielding portion 5 can be automatically squeezed out without manual assistance to remove, ensuring that the driving portion can drive the two support mechanisms 4 and the two segmented wind turbine flanges to be completely fitted, and the efficiency is further improved.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.

A method for using a segmented wind turbine flange installation auxiliary tool, applied to the segmented wind turbine flange installation auxiliary tool according to any one of claims 1 to 6, characterized in that: The method of use comprises the following steps: Step 1: Install the first support assembly (1) and the second support assembly (2), align both ends of the two, ensure that they are parallel to each other, and then fix them; Step 2: Place the two sliced ​​wind turbine flanges symmetrically, lift the two sliced ​​wind turbine flanges by external lifting equipment, and move them above the first support assembly (1) and the second support assembly (2). Ensure that the outer ring surfaces at both ends of the two sliced ​​wind turbine flanges can contact the corresponding support mechanisms (4). Then, cut the material so that the four support mechanisms (4) support the two sliced ​​wind turbine flanges. During the supporting process, the shielding portion (5) supports the side end faces of the sliced ​​wind turbine flanges. Step 3: The internal driving parts of the first supporting assembly (1) and the second supporting assembly (2) are operated to drive the connected supporting mechanisms (4) to move closer to each other, and simultaneously drive the two ends of the two sliced ​​wind turbine flanges to move closer to each other. During the moving closer process, the shielding parts (5) on the side of the supporting mechanism (4) are contacted and closed in advance. After closing, the driving parts continue to work, and the two shielding parts (5) that are in contact with each other are pressed together. Finally, the two shielding parts (5) are squeezed out, so that the lower end faces of the two sliced ​​wind turbine flanges are pressed together, and then the lower end faces of the two sliced ​​wind turbine flanges are connected and fixed.
