Description

Technical Field

[0001] The utility model belongs to the technical field of wind power devices, in particular to a wind power tower maintenance device. Background Art

[0002] The device required for wind power generation is called a wind turbine generator set, which can be roughly divided into three parts: the wind rotor, the generator and the wind turbine tower. The oil stains on the outer wall of the wind turbine tower need to be cleaned in time, the appearance of the blades needs to be inspected regularly, and the lightning arrester at the tip of the blade needs to be regularly grounded and measured for high-altitude operations. At present, the above maintenance work is carried out manually using a hanging basket for high-altitude maintenance. The labor cost is very high, and it is very dangerous for maintenance personnel to use the hanging basket. The maintenance personnel spend a lot of time installing and disassembling the hanging basket and its related accessories. The wind turbine is shut down for a long time, resulting in serious power loss. The existing technical solutions have not proposed solutions for the situation that manual high-altitude maintenance takes a long time and the wind turbine is shut down for a long time, resulting in serious power loss.

[0003] A Chinese patent discloses a wind turbine tower maintenance device (publication number CN220059814U). The patent connects the lifting rope of the lifting assembly to the bracket of the traction assembly designed on the outer wall of the tower of the wind turbine group to achieve the connection between the lifting rope and the required load-bearing maintenance equipment. The device is easy and quick to install and disassemble, economical and durable. The device can be used to carry out partial high-altitude maintenance work on the outer wall of the tower of the wind turbine group, reduce manual hanging basket operations, improve maintenance work efficiency, and avoid the problem of long-term shutdown of the wind turbine and serious power loss during the maintenance process. However, when the patent is in use, the maintenance position and the gap space area are limited and cannot be rotated, resulting in partial contact and maintenance of the cylinder, which in turn affects the maintenance effect of the cylinder and cannot adapt to the maintenance needs of different positions of the cylinder. Utility Model Content

[0004] In order to solve the problem that the prior art cannot rotate and cannot adapt to the maintenance needs of different positions of the cylinder, the utility model provides a wind turbine tower maintenance device. When the device needs to be used to repair the cylinder, the maintenance personnel first need to stand on the maintenance platform and then drive the motor. The rotation of the output shaft of the motor can drive the top block to rotate. The rotation of the top block can drive the toothed belt fixedly connected to its bottom to rotate. When the toothed belt rotates, it can drive the toothed block meshing with it to rotate. The rotation of the toothed block can drive the first rotating rod to rotate on the side of the fixed block. The rotation of the first rotating rod can drive the pull rope to be reeled around the periphery of the first rotating rod, thereby pulling the support block to be lifted around the periphery of the cylinder. At the same time, when the support block is lifted, it will roll around the periphery of the cylinder through the roller, thereby increasing the lifting speed of the support block and improving the smoothness of the support block when lifting. The maintenance platform is installed on the side of the support block, and the maintenance personnel can be driven to move to the appropriate position of the outer wall of the cylinder to inspect the cylinder. Since the cylinder is cylindrical, when it is necessary to inspect different positions of the outer wall of the cylinder, the maintenance platform can be rotated by rotating the threaded column. At this time, the protrusion and the limit slide bar on one side of the maintenance platform can be rotated on the periphery of the support block by pushing the threaded column. After rotating to the appropriate position, the maintenance platform can be fixed again by the threaded column to realize the maintenance needs of different positions of the cylinder, thereby improving the maintenance effect and maintenance area of ​​the cylinder, further improving the maintenance effect of the cylinder, and increasing the service life of the cylinder.

However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0023] Example 1: Figure 1-6 As shown, the utility model aims to provide a wind power tower maintenance device to solve the problem in the prior art that the maintenance device cannot be rotated and cannot adapt to the maintenance needs of different positions of the cylinder. According to the above functions, the entire device includes a cylinder 1, a fixed base 2 is fixedly installed at the bottom end of the cylinder 1, a support block 3 is arranged on the periphery of the cylinder 1, and a lifting mechanism for height adjustment is arranged between the support block 3 and the cylinder 1, and a maintenance platform 7 is arranged on the side of the support block 3. The maintenance platform 7 is rotatably sleeved on the periphery of the support block 3, and a threaded column 5 for fixing the maintenance platform 7 is arranged on the top of the support block 3. When the cylinder 1 is repaired, the maintenance platform 7 can be controlled by the threaded column 5, so as to realize the fixation and rotation of the maintenance platform 7, so as to adapt to the maintenance needs of different positions of the cylinder 1 and improve the maintenance effect.

Both ends of the limit slide bar 20 are slidably sleeved on the periphery of the support block 3. A rotating groove that is mutually compatible with the protrusion 19 and the limit slide bar 20 is provided on the periphery of the support block 3, thereby adapting to the rotation requirements of the protrusion 19 and the limit slide bar 20, and then adapting to the maintenance requirements of different positions of the cylinder 1, thereby improving the maintenance effect.

[0025] like Figure 5As shown, a support block 16 is fixedly connected to the bottom of the maintenance platform 7, a first fixed rod 17 is fixedly connected to the bottom of the support block 16, a rotating block 18 is fixedly connected to the end of the first fixed rod 17 away from the support block 16, the rotating block 18 is rotatably sleeved in the bottom inner cavity of the support block 3, and a rotating groove that is compatible with the rotating block 18 is provided at the bottom of the support block 3, so as to facilitate the rotation of the rotating block 18, and the support block 16, the first fixed rod 17 and the rotating block 18 can play a supporting role for the maintenance platform 7 to prevent the maintenance platform 7 from collapsing due to uneven force.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the lifting mechanism includes a motor 8 fixedly installed in the inner cavity of the top end of the cylinder 1. The motor 8 can provide power support for the lifting mechanism. The output end of the motor 8 is fixedly connected to the top block 4. The top block 4 is located at the top of the cylinder 1 and does not contact the top of the cylinder 1. However, since the top of the top block 4 is set to an arc surface, the accumulation of dust and impurities can be avoided. The bottom of the top block 4 is fixedly connected to a toothed belt 9, and the toothed belt 9 is non-meshingly connected to a plurality of tooth blocks 10. The shape of the toothed belt 9 is the same as the shape of the bottom end of the top block 4, both of which are circular, so that it is convenient to drive the rotation of the toothed belt 9 by the rotation of the top block 4 to meet the rotation requirements of the tooth block 10.

[0027] like Figure 3 As shown, the side of the tooth block 10 is fixedly connected with a first rotating rod 11, and the first rotating rod 11 and the tooth block 10 are fixedly sleeved with each other. The rotation of the tooth block 10 can drive the first rotating rod 11 to rotate. The end of the first rotating rod 11 away from the tooth block 10 is rotatably sleeved with a fixed block 12, and the fixed block 12 is fixedly installed on the top outer wall of the cylinder 1. The fixed block 12 can support the installation of the first rotating rod 11 and the tooth block 10.

[0028] like Figure 2 and Figure 4 As shown, a pull rope 6 is sleeved on the outer periphery of the first rotating rod 11, and a pull ring 14 is fixedly connected to one end of the pull rope 6 away from the first rotating rod 11, and a pull block 15 is movably sleeved on the side of the pull ring 14. The pull block 15 is fixedly installed on the inner wall of the support block 3 through the connecting block 13. The pull block 15 and the pull ring 14 can connect and fix the pull rope 6 and the support block 3, thereby lifting the support block 3. The inner wall of the support block 3 is fixedly connected to a roller 21 through a second fixed rod 22, and the roller 21 is slidably sleeved on the outer wall of the cylinder 1. A rolling groove is opened on the periphery of the cylinder 1, and the roller 21 rolls along the rolling groove, thereby improving the smoothness of lifting the support block 3.

[0029] Working principle of this device:

[0030] When it is necessary to use the present device to inspect the cylinder body 1, the inspection personnel first need to stand on the inspection platform 7, and then drive the motor 8. The rotation of the output shaft of the motor 8 can drive the top block 4 to rotate. The rotation of the top block 4 can drive the toothed belt 9 fixedly connected to its bottom to rotate. When the toothed belt 9 rotates, it can drive the toothed block 10 meshing with it to rotate. The rotation of the toothed block 10 can drive the first rotating rod 11 to rotate on the side of the fixed block 12. The rotation of the first rotating rod 11 can drive the pull rope 6 to be reeled around the periphery of the first rotating rod 11, thereby pulling the support block 3 to lift the periphery of the cylinder body 1. At the same time, when the support block 3 is lifted, it will roll on the periphery of the cylinder body 1 through the roller 21, thereby increasing the lifting speed of the support block 3 and improving the smoothness of the lifting of the support block 3. During the lifting process, according to the inspection needs of the cylinder body 1, By turning off the motor 8, the position of the support block 3 is driven. Since the maintenance platform 7 is installed on the side of the support block 3, it can drive the maintenance personnel to move to the appropriate position of the outer wall of the cylinder 1 and inspect the cylinder 1. Since the cylinder 1 is cylindrical, when it is necessary to inspect different positions of the outer wall of the cylinder 1, the threaded column 5 can be rotated to make the maintenance platform 7 in an unfixed rotation. At this time, by pushing the threaded column 5, the protrusion 19 and the limiting slide bar 20 on one side of the maintenance platform 7 can be rotated on the periphery of the support block 3. After rotating to the appropriate position, the maintenance platform 7 is fixed again by the threaded column 5, thereby realizing the maintenance needs of different positions of the cylinder 1, thereby improving the maintenance effect and maintenance area of ​​the cylinder 1, further improving the maintenance and maintenance effect of the cylinder 1, and increasing the service life of the cylinder 1.
