Description

Technical Field

[0001] This invention belongs to the field of auxiliary installation technology for steel-concrete towers, specifically an auxiliary installation platform for steel-concrete towers. Background Technology

[0002] A reinforced concrete tower auxiliary installation platform is a structure used to support and provide a working platform. It is typically used in the construction and maintenance of high-rise buildings or tower structures. These platforms can provide a safe working space on the upper part of the building structure, making it convenient for workers to carry out installation, maintenance or repair work.

[0003] A patent with publication number CN211714547U discloses a telescopic accessory installation auxiliary platform for steel-concrete towers, including a platform panel and a lifting disc. The platform panel includes a first panel and a second panel, both of which are semi-circular with the same specifications. The lifting disc is fixed at the center of the first panel. A first fixing hole is opened on the upper surface of the first panel, and a second fixing hole is opened on the upper surface of the second panel. The same threads are opened inside the first and second fixing holes. The installation auxiliary platform can be controlled to have a large retractable range and a wide range of applications through the same telescopic mechanism on the first and second panels. This greatly reduces the difficulty of accessory installation in the concrete section of the steel-concrete tower, greatly improves the efficiency of accessory installation, and also provides safety for workers working at height.

[0004] The above-mentioned solution still has some problems in practical application. When installing the fan blades using the existing installation platform, after the fan blades are lifted, due to the height of the installation tower and the large size and weight of the fan blades, the angle will be offset due to the wind force at high altitude. This will cause the mating structure of the fan blades to not match the mating components on the fan drive shaft. Therefore, it is necessary to perform a mating and correction operation between the fan blades and the fan drive shaft. However, the mating work is generally very difficult. If the fan blades are directly inserted into the fan drive shaft without correction, the fan blades and the drive shaft will collide and wear during the mating, thereby reducing the service life of the fan in subsequent use. In the existing mating process, workers usually need to be lifted up with the fan blades and then correct the mating of the fan blades. However, since the auxiliary installation of the fan blades is a high-altitude operation, the mating process is not easy. Workers need to make multiple angle adjustments to complete the mating. This process is highly dangerous and inefficient.

[0005] Therefore, the present invention provides an auxiliary installation platform for steel-concrete towers. Summary of the Invention

[0015] Preferably, a limiting post is rotatably provided in the first cavity. The limiting post is driven to rotate by a motor in the auxiliary platform. Two fixing rings are fixedly connected to the middle of the limiting post. Two positioning blocks are fixedly connected to the end of the adjusting plate near the rotating disk. The two positioning blocks are fixedly connected to the same fixed shaft. The fixed shaft and the limiting post are connected by a connecting cable.

[0016] Preferably, the rotating disk is provided with a positioning shaft that rotates to the position of the adjusting plate, and a torsion spring is sleeved on the circumferential surface of the positioning shaft, so that the adjusting plate can be unfolded by the torsion of the torsion spring.

[0017] Preferably, the fixed plate is provided with two first steel strips, and each end of the two first steel strips is provided with a transmission roller.

[0018] Preferably, the upper surface of the base is provided with a rotating frame, and a rotating shaft is rotatably disposed within the rotating frame. The rotating shaft is fixedly connected to the support frame, and the support frame can be adjusted at a certain angle within the rotating frame via the rotating shaft.

[0019] Preferably, a first hydraulic cylinder is fixedly connected to each of the four corners of the upper surface of the base, a connecting column is fixedly connected to the output end of each first hydraulic cylinder, a positioning plate is fixedly connected to the bottom end of each connecting column, and a positioning cone is fixedly connected to the lower surface of each positioning plate.

[0020] Preferably, a rotating column is fixedly connected between the two top blocks, and a fixing rope is fixedly connected to the circumferential surface of the rotating column. The end of the fixing rope away from the top block is fixedly connected to a connecting plate, and the connecting plate can be equipped with a lifting device to fix the fan blades.

[0021] Preferably, a fixing block is fixedly connected to the top of the support frame, a connecting shaft is rotatably provided on one side of the fixing block, a connecting block is fixedly connected to the circumferential surface of the connecting shaft, the upper surface of the connecting block is fixedly connected to the connecting frame, and several rotating rollers are drivenly provided on both sides of the bottom of the base, and the circumferential surfaces of the several rotating rollers are drivenly connected to the same transmission track, and the two transmission tracks can drive the auxiliary installation platform to move.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The steel-concrete tower auxiliary installation platform of the present invention involves moving the auxiliary platform along the fixed plate towards the top of the connecting frame. When it reaches the middle position of the corresponding wind turbine blade, the adjusting plate inside the platform is released. The adjusting plate rotates to the side of the rotating disk away from the auxiliary platform. Then, the motor inside the auxiliary platform is started to drive the rotating disk to rotate. This rotation is very slight because after the adjusting plate rotates to the side close to the wind turbine blade, it is located between the two wind turbine blades. A slight rotation of the adjusting plate will bring the adjusting plate into contact with the wind turbine blade, thus driving the wind turbine blade to rotate and adjust. In the existing docking process, workers usually need to be hoisted up with the wind turbine blade and then perform the adjustment work at high altitude. However, when performing angle adjustment, multiple angle adjustments are usually required to complete the docking. The angle adjustment process is cumbersome, and high-altitude work is also very dangerous, resulting in low work efficiency.

[0024] 2. The steel-concrete tower auxiliary installation platform of the present invention features a limit post rotatably mounted at one end of a rotating disk near the first cavity. A connecting rope between two fixed rings is then fixed to a fixed shaft on an adjusting plate. When the adjusting plate rotates, the motor controlling the limit post starts simultaneously, releasing the connecting rope on the limit post. This allows the adjusting plate to rotate to the side of the rotating disk near the fan blades. After the adjusting plate completes its adjustment of the fan blades, the auxiliary platform controls the rotating disk's motor to reset the rotating disk, simultaneously resetting the adjusting plate. Then, by starting the limit post's motor, the connecting rope is wound up by the limit post. This winding process causes the adjusting plate to re-enter the first cavity. Finally, energizing the electrophoretic magnetic plate re-fixes the adjusting plate, achieving automatic retraction and protecting the adjusting plate. Attached Figure Description

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Example 1

[0042] like Figures 1 to 10 As shown in the embodiment of the present invention, an auxiliary installation platform for a steel-concrete tower includes a base 1, a support frame 22 rotatably mounted on the upper surface of the base 1, and a connecting frame 26 rotatably mounted on the top of the support frame 22. Two top blocks 4 are fixedly connected to the top of the connecting frame 26, and a connecting plate 43 is fixedly connected between the two top blocks 4. An angle adjustment assembly is slidably mounted on one side of the connecting frame 26. The angle adjustment assembly includes a fixing plate 27 fixedly mounted on the surface of the connecting frame 26; an auxiliary platform 210 slidably mounted on one side of the fixing plate 27; a rotating disk 212 fixedly mounted on the motor output end within the auxiliary platform 210; and an adjustment plate 225 rotatably mounted on the surface of the rotating disk.

[0043] Specifically, during the installation of wind turbine blades using the existing installation platform, after the blades are lifted, due to the height of the installation tower and the large size and weight of the blades, the blades may experience angular displacement due to the high-altitude wind force. This can cause the blade mating structure to misalign with the mating components on the wind turbine drive shaft, necessitating alignment and correction of the blades and drive shaft. However, this alignment process is generally very difficult. If the blades are inserted directly into the drive shaft without alignment, collisions and wear may occur, reducing the wind turbine's lifespan. Current alignment methods typically require workers to be lifted along with the blades and then perform alignment at height. However, this often requires multiple angle adjustments to complete the alignment. Because the blades are so large, even small angular displacements make the alignment process cumbersome, and working at height is dangerous, resulting in low efficiency for workers.

[0044] Therefore, this invention includes an angle adjustment component to replace manual adjustment of the fan blades that have shifted, thereby extending the service life of the fan. When using an existing installation platform, the operator first drives the auxiliary installation platform to the location of the fan blades to be hoisted. Once the operator reaches this location, the support frame 22 is adjusted to ensure that the equipment on the installation platform is functioning properly and without any damage. Because hoisting and connecting the fan blades is a large-scale operation, it is essential to ensure that the equipment is functioning correctly. After confirmation, the operator installs the hoisting fixing device on the connecting plate 43. This fixing device is used to secure the fan blades, ensuring stability during the hoisting process. The support frame 22 is then rotated. Raise the support frame 22 to near vertical ground, then rotate the connecting frame 26. Simultaneously, the hydraulic cylinder mounted on the support frame 22 lowers the connecting frame, placing the connecting plate 43 on the ground. Workers can then use the installed hoisting device to secure the wind turbine blades to the connecting plate 43. Next, rotate the connecting frame 26 at the top of the support frame 22 and activate the hydraulic cylinder on the support frame 22, causing the connecting frame 26 to slowly rise. The rising connecting frame 26 will gradually raise the wind turbine blades. Once the middle of the wind turbine blades is aligned with the wind turbine's drive shaft, slowly rotate the connecting frame 26 downwards while simultaneously raising the connecting plate 43, bringing the wind turbine blades closer to the wind turbine's drive shaft. At this point, because the wind turbine is suspended at a high altitude, it is subjected to... The influence of high-altitude winds can cause slight angular deviations, but these deviations must be eliminated. Otherwise, the fan blades and drive shaft will collide and wear during connection, reducing the fan's lifespan. Therefore, by starting the auxiliary platform 210 and moving it along the fixed plate 27 towards the top of the connecting frame 26, when it reaches the middle position of the corresponding fan blade, the adjusting plate 225 inside the platform is released. The adjusting plate 225 will rotate to the side of the rotating disk 212 away from the auxiliary platform 210. Then, the motor inside the auxiliary platform 210 is started to drive the rotating disk 212 to rotate. This rotation is very slight because after the adjusting plate 225 rotates to the side closer to the fan blade, it is positioned between the two fan blades. A slight rotation of the adjusting plate 225 will... This will cause the adjusting plate 225 to contact the fan blades, which will then drive the fan blades to rotate and adjust. Ground personnel can observe through a camera whether the docking structure on the fan blades matches the docking component on the fan's drive shaft. If the docking angle is confirmed, the connecting frame 26 will continue to move towards the fan, thus successfully docking. This prevents the docking structure on the fan blades from colliding with the fan's drive shaft, thereby solving the problem that in the existing docking process, personnel usually need to be hoisted up with the fan blades and then perform the adjustment work at high altitude. However, when adjusting the angle, multiple angle adjustments are usually required to complete the docking, which is cumbersome, dangerous, and inefficient.

[0045] like Figure 2 As shown, in this embodiment, guide grooves 29 are provided on both sides of the fixed plate 27, and connecting rods 211 are fixedly connected to both sides of the auxiliary platform 210. The other end of the connecting rod 211 is adapted to the guide groove 29 and can slide within the guide groove 29.

[0046] Specifically, when using the auxiliary platform 210, as it is started and moved upward along the fixed plate 27, the connecting rods 211 on both sides of the auxiliary platform 210 can slide along the guide grooves 29 on the fixed plate 27. This makes the auxiliary platform 210 more stable as it slides upward along the fixed plate 27, and also makes the force on the auxiliary platform 210 stable during the upward movement. This also allows the auxiliary platform 210 to work more stably during the subsequent adjustment of the fan blades.

[0047] like Figure 6 As shown, the lower surface of the auxiliary platform 210 in this embodiment is provided with a first cavity 213. An electrophoretic magnetic plate 217 is fixedly connected to the top wall of the first cavity 213. A first groove 215 is provided on the adjustment plate 225 corresponding to the position of the electrophoretic magnetic plate 217. A first magnetic plate 216 is fixedly connected to the first groove 215. The first magnetic plate 216 can be magnetically attracted to the electrophoretic magnetic plate 217.

[0048] Specifically, after the auxiliary platform 210 moves to the middle of the corresponding fan blade, the adjustment plate 225, which is magnetically attached to the first cavity 213, is released, thereby adjusting the angle of the fan blade. Specifically, the electrophoretic magnetic plate 217 on the top wall of the first cavity 213 is de-energized. At this time, the electrophoretic magnetic plate 217 loses its magnetism and loses its magnetic attraction with the first magnetic plate 216. The first magnetic plate 216, which loses its magnetic attraction, rotates out of the first cavity 213 and rotates to the side of the rotating disk 212 close to the fan blade, achieving the effect of rapid automatic rotation and release.

[0049] like Figure 6 and Figure 7 As shown, in this embodiment, a limiting post 218 is rotatably installed in the first cavity 213. The limiting post 218 is driven to rotate by a motor in the auxiliary platform 210. Two fixing rings 219 are fixedly connected to the middle of the limiting post 218. Two positioning blocks 221 are fixedly connected to one end of the adjusting plate 225 near the rotating disk 212. The same fixing shaft 222 is fixedly connected between the two positioning blocks 221. The fixing shaft 222 and the limiting post 218 are connected by a connecting rope 220.

[0050] Specifically, during the process of the adjusting plate 225 rotating from the first cavity 213 to the side of the rotating disk 212 near the fan blades, a limit post 218 is rotatably set at one end of the rotating disk 212 near the first cavity 213. This limit post 218 is then fixed to the fixed shaft 222 on the adjusting plate 225 via a connecting cable 220 between two fixing rings 219. When the adjusting plate 225 rotates, the motor controlling the limit post 218 starts simultaneously, releasing the connecting cable 220 on the limit post 218, thus allowing the adjusting plate 225 to rotate to the side of the rotating disk 212 near the fan blades. Then, the adjustment... After the section plate 225 completes the adjustment of the fan blades, the auxiliary platform 210 controls the motor of the rotating disk 212 to reset the rotating disk 212, which also drives the adjustment plate 225 to reset. Then, by starting the motor of the limit post 218, the connecting cable 220 is driven, which enables the limit post 218 to wind up the connecting cable 220. While winding up, the adjustment plate 225 will be driven back into the first cavity 213. Then, the electrophoretic magnetic plate 217 is energized to fix the adjustment plate 225 again, achieving the effect of automatic retraction of the adjustment plate 225 and protecting the adjustment plate 225.

[0051] like Figure 6 As shown, in this embodiment, the rotating disk 212 is rotatably provided with a positioning shaft 223 corresponding to the position of the adjusting plate 225. A torsion spring 224 is sleeved on the circumferential surface of the positioning shaft 223, and the adjusting plate 225 can be unfolded by the torsion of the torsion spring 224.

[0052] Specifically, during the rotation of the adjusting plate 225 after losing its magnetic force, the positioning shaft 223 rotates at one end of the adjusting plate 225 near the rotating disk 212. The positioning shaft 223 drives the adjusting plate 225 to rotate through the torsion springs 224 sleeved at both ends of the positioning shaft 223. At the instant the electrophoretic magnetic plate 217 is de-energized, the torque of the torsion springs 224 drives the adjusting plate 225 to rotate in the direction of the fan blades, preventing the adjusting plate 225 from rotating with excessive impact force. Therefore, the auxiliary platform 210 is connected to the adjusting plate 225 through the connecting cable 220, which can also drive the adjusting plate 225 to reset for the next use.

[0053] like Figure 2 As shown, in this embodiment, the fixed plate 27 is equipped with two first strips 28 for transmission, and each end of the two first strips 28 is equipped with a transmission roller 214.

[0054] Specifically, during the upward movement of the auxiliary platform 210 along the fixed plate 27, two first strip steels 28 are connected by a transmission roller 214 inside the fixed plate 27. By fixing the auxiliary platform 210 to the two first strip steels 28, the auxiliary platform 210 can be driven to move upward along the fixed plate 27. After the adjustment work is completed, it can also return to the bottom of the connecting frame 26 along the fixed plate 27, so as not to hinder the top of the fan blades from being lifted.

[0055] Example 2

[0056] like Figures 4 to 10 As shown in the first embodiment, another embodiment of the present invention is as follows: a rotating frame 2 is provided on the upper surface of the base 1, and a rotating shaft 21 is rotatably provided in the rotating frame 2. The rotating shaft 21 is fixedly connected to the support frame 22, and the support frame 22 can be adjusted at a certain angle in the rotating frame 2 by means of the rotating shaft 21.

[0057] Specifically, when the support frame 22 is initially driven, the support frame 22, which is fixed to the rotating shaft 21 inside the rotating frame 2, is driven by rotating the rotating shaft 21. This achieves the effect of rotating the support frame 22 to be nearly perpendicular to the ground, so that the connecting frame 26 can be adjusted and controlled to rotate and rise for hoisting operations.

[0058] like Figure 8 As shown, in this embodiment, a first hydraulic cylinder 3 is fixedly connected to each of the four corners of the upper surface of the base 1. A connecting column 31 is fixedly connected to the output end of each first hydraulic cylinder 3. A positioning plate 32 is fixedly connected to the bottom end of each connecting column 31. A positioning cone 33 is fixedly connected to the lower surface of each positioning plate 32.

[0059] Specifically, the staff drives the auxiliary installation platform to the position of the wind turbine blades to be hoisted. By activating each of the four first hydraulic cylinders 3 at the four corners of the upper surface of the base 1, the first hydraulic cylinder 3 will drive the connecting column 31 fixed in its output end to move towards the ground. At the same time, the connecting column 31 will drive the positioning plate 32 fixed in its ground to move downward. The positioning plate 32 will drive several positioning cones 33 fixed in its ground. Since the wind turbine is installed in the field, it is generally on soil. Therefore, by inserting the positioning cones 33 into the ground and then making the positioning plate 32 abut against the ground, the installation platform is fixed and positioned, so that the installation platform can achieve a more stable effect when hoisting.

[0060] like Figure 10 As shown, in this embodiment, a rotating column 41 is fixedly connected between the two top blocks 4. A fixing cable 42 is fixedly connected to the circumferential surface of the rotating column 41. The end of the fixing cable 42 away from the top block 4 is fixedly connected to the connecting plate 43. The connecting plate 43 can be equipped with a lifting device to fix the fan blades.

[0061] Specifically, when using the fixing plate at the top of the connecting frame 26, a rotating column 41 is rotatably installed between the two top blocks 4 at the top of the connecting frame 26. The rotating column 41 is controlled by a motor. After the connecting frame 26 is rotated to the ground, the fan blades are fixed by installing a hanging fixing device on the connecting plate 43. After the fan blades are lifted to be aligned with the drive shaft of the fan, the connecting frame 26 is rotated, and then the motor in the top block 4 is started to wind up the fixing cable 42, so that the fan blades are close to the drive shaft of the fan while always maintaining alignment with it.

[0062] like Figure 4 and Figure 9 As shown, in this embodiment, a fixing block 23 is fixedly connected to the top of the support frame 22, and a connecting shaft 25 is rotatably provided on one side of the fixing block 23. A connecting block 24 is fixedly connected to the circumferential surface of the connecting shaft 25. The upper surface of the connecting block 24 is fixedly connected to the connecting frame 26. Several rotating rollers 11 are driven to be provided on both sides of the bottom of the base 1. The circumferential surfaces of the several rotating rollers 11 are driven to be connected to the same transmission track 12. The two transmission tracks 12 can drive the auxiliary installation platform to move.

[0063] Specifically, by setting a fixing block 23 at the top of the support frame 22, and then fixing a motor inside the fixing block 23, the motor inside the fixing block 23 drives the connecting shaft 25, thereby driving the connecting block 24 to rotate, and then driving the connecting frame 26 to rotate, so as to complete the hoisting work of the fan blades.

[0064] Working principle: During the installation of wind turbine blades using the existing installation platform, after the blades are lifted, due to the height of the installation tower and the large size and weight of the blades, the blades may experience angular displacement due to the wind force at high altitudes. This can cause the blade mating structure to misalign with the mating components on the wind turbine drive shaft, necessitating alignment and correction of the blades and drive shaft. However, this alignment process is generally very difficult. If the blades are inserted directly into the drive shaft without alignment, collisions and wear may occur, reducing the wind turbine's lifespan. Existing alignment methods typically require workers to be lifted along with the blades and then perform alignment work at high altitudes. However, this often requires multiple angle adjustments to complete the alignment. Because the blades are so large, even small angular displacements make the alignment process cumbersome, and working at heights is dangerous, resulting in low efficiency for workers.

[0065] Therefore, this invention provides an angle adjustment component to replace manual adjustment of the angle of the fan blades that have shifted, thereby extending the service life of the fan. When using the existing installation platform, the staff first drive the auxiliary installation platform to the position of the fan blades to be hoisted. After the staff reaches the position, the support frame 22 is adjusted to ensure that the equipment on the installation platform is in good working order and without any damage. Because hoisting and docking the fan blades is a large-scale operation, it is necessary to ensure that the equipment is in good working order. After confirmation, the staff installs the hoisting fixing device on the connecting plate 43. This fixing device is used to fix the fan blades, thereby ensuring stability during the hoisting process. The support frame 22 is rotated to raise it close to the vertical ground. Then the connecting frame 26 is rotated and the hydraulic cylinder installed on the support frame 22 is used to lower the connecting frame 26, placing the connecting plate 43 on the ground. The staff can then fix the fan blades to the connecting plate 43 using the hoisting fixing device after installation.

[0066] Then, by activating the motor inside the fixed block 23 to drive the connecting shaft 25, the connecting block 24 rotates. Simultaneously, the hydraulic cylinder mounted on the support frame 22 pushes the connecting frame 26 up, causing it to rotate and slowly rise. The rising connecting frame 26 then gradually raises the fan blades. Once the fan blades are aligned with the fan's drive shaft, the connecting frame 26 is slowly rotated downwards, while the connecting plate 43 is simultaneously lifted, bringing the fan blades closer to the wind turbine's drive shaft. At this point, because the wind turbine is suspended at a high altitude, it will experience a slight angular shift due to the influence of high-altitude winds. This offset must be eliminated, otherwise the fan blades and drive shaft will collide and wear when they are connected, thus reducing the service life of the fan in subsequent use. Therefore, by starting the transmission roller 214 to drive the first strip 28 to rotate, the auxiliary platform 210 will move along the fixed plate 27 to the top of the connecting frame 26. During the upward movement of the auxiliary platform 210 along the fixed plate 27, the connecting rods 211 on both sides of the auxiliary platform 210 can also slide along the guide grooves 29 opened on the fixed plate 27, thereby achieving a more stable effect for the auxiliary platform 210 during the upward sliding along the fixed plate 27.

[0067] When the adjustment plate 225 moves to the middle position of the corresponding fan blade, it releases the magnetic attraction of the adjustment plate 225 set in the first cavity 213, thereby adjusting the angle of the fan blade. Specifically, firstly, the electrophoretic magnetic plate 217 on the top wall of the first cavity 213 is de-energized, at which point the electrophoretic magnetic plate 217 loses its magnetism and then loses its magnetic attraction with the first magnetic plate 216. The first magnetic plate 216, having lost its magnetic attraction, rotates out of the first cavity 213 and rotates to the side of the rotating disk 212 near the fan blade. During the process of the adjustment plate 225 rotating from the first cavity 213 to the side of the rotating disk 212 near the fan blade, a limit post 218 is rotated at one end of the rotating disk 212 near the first cavity 213, and then the connecting rope 220 between the two fixing rings 219 is fixed to the fixing shaft 222 on the adjustment plate 225. When the adjusting plate 225 rotates, the motor controlling the limiting post 218 will start simultaneously, releasing the connecting cable 220 on the limiting post 218, so that the adjusting plate 225 can rotate to the side of the rotating disk 212 close to the fan blades. After the adjusting plate 225 completes the adjustment of the fan blades, the auxiliary platform 210 controls the motor of the rotating disk 212 to reset the rotating disk 212, which can also drive the adjusting plate 225 to reset. Then, by starting the motor of the limiting post 218, the connecting cable 220 can be driven, so that the limiting post 218 can wind up the connecting cable 220. While winding, the adjusting plate 225 will be driven back into the first cavity 213. Then, the electrophoretic magnetic plate 217 is energized to fix the adjusting plate 225 again, achieving the effect of automatic retraction of the adjusting plate 225 and protecting the adjusting plate 225.

[0068] Then, the motor inside the auxiliary platform 210 is started to drive the rotating disk 212 to rotate. This rotation is very slight because after the adjusting plate 225 rotates to the side close to the fan blades, it is located between the two fan blades. A slight rotation of the adjusting plate 225 will make the adjusting plate 225 contact the fan blades, and then the fan blades can be rotated and adjusted. The ground staff observes through the camera whether the docking structure on the fan blades matches the docking component on the fan drive shaft. If the docking angle is confirmed, the connecting frame 26 is driven to move towards the fan, thus the docking is successful. The docking structure of the fan blades will not collide with the fan drive shaft. This solves the problem that in the existing docking process, the staff usually need to be lifted up with the fan blades and then perform the adjustment work at high altitude. However, the angle adjustment usually requires multiple angle adjustments to complete the docking. The angle adjustment process is cumbersome, the high-altitude operation is very dangerous, and the work efficiency is low.
