DETAILED DESCRIPTION

[0023] The following will be combined with the 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 embodiments described 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.

[0024] like Figure 1-Figure 3 As shown, the wind turbine tower maintenance climbing frame provided in the embodiment of the present application includes a support base 100, a first clamping ring 200, a second clamping ring 500, a column 400, and a hanging basket 800. The support base 100 is the supporting structure of the maintenance climbing frame. The first clamping ring 200 is provided at the bottom end of the support base 100 near the side of the tower. The inner ring shape of the first clamping ring 200 is semicircular, and the inner diameter of the first clamping ring 200 is larger than the outer diameter of the tower, so that the first clamping ring 200 can be installed outside the tower. Fastening screws 300 are also threadedly connected at both ends of the first clamping ring 200, and the fastening screws 300 can be used to fix the first clamping ring 200 to the tower.

[0025] The column 400 is hingedly mounted on the support base 100. A second retaining ring 500 is located on the top side of the column 400, near the tower. The inner ring of the second retaining ring 500 is also semicircular. Furthermore, the second retaining ring 500 is capable of engaging with the outer wall of the tower. A drive motor is located at the bottom end of the column 400. Specifically, a motor base 410 extends outward from the top surface of the column 400, and a drive motor 600 is mounted on the motor base 410. A drive screw 700 is fixedly connected to the drive end of the drive motor 600. The drive screw 700 is located opposite the second retaining ring 500 and is rotatably connected to the upper surface of the support base 100. Furthermore, the drive screw 700 is parallel to the column 400 and is spaced a predetermined distance from the wall of the column 400 to ensure that the drive screw 700 does not rub against the column 400 during rotation.

[0026] The hanging basket 800 is sleeved on the outside of the column 400 by the ring sleeve 900, and the hanging basket 800 is also threadedly connected with the driving screw 700. The hanging basket 800 can move up and down along the column 400 under the action of the driving screw 700.

[0027] In the wind turbine tower maintenance climbing frame provided in the embodiment of the present application, a first clamping ring 200 is provided on the side of the support base 100 near the tower. The first clamping ring 200 can be mounted outside the tower and the support base 100 is fixed to the bottom end of the tower by a fastening screw 300. At the same time, the upper surface of the support base 100 is hingedly connected to a column 400. The top of the wall where the column 400 contacts the tower is provided with a second clamping ring 500. The second clamping ring 500 can be used to make the column 400 slightly tilted against the tower and achieve position limiting. In actual use, a staff member can stand in the hanging basket 800 and start the driving screw 700 by controlling the drive motor 600 to rotate, thereby achieving the lifting and lowering operation of the hanging basket 800. With the above structural design, the base of the climbing frame is fixed to the bottom end of the tower by the first clamping ring 200 and the fastening screw 300, which can effectively prevent the risk of the bottom of the climbing frame from sliding. At the same time, the column 400 is slightly tilted against the tower pole and is limited by the second clamping ring 500 at the top of the column 400, which can further reduce the chance of the climbing frame being blown down in windy weather, thereby effectively ensuring the life and health of the staff.

[0028] In some embodiments, the upper surface and lower surface of the support base 100 and the first clamping ring 200 are parallel to each other, and the support base 100 and the first clamping ring 200 are integrally formed, which can ensure the overall structural stability of the maintenance climbing frame to prevent breakage during use.

[0029] In some embodiments, a rectangular hole 910 is provided on one of the walls of the ring sleeve 900 that is slidably connected to the column 400. A plurality of rollers 920 are disposed within the rectangular hole 910. The ring sleeve 900 is slidably connected to the column 400 via the plurality of rollers 920. The above structure not only improves the smoothness of movement of the hanging basket 800, but also reduces damage caused by sliding friction between the ring sleeve 900 and the column 400, thereby extending the service life of the related components.

[0030] Preferably, an operating plate 930 may be provided on the ring sleeve 900. The operating plate 930 is provided with a plurality of holes 940 along the thickness direction. The operating plate 930 is slidably connected to a claw plate 950 through the holes 940. Figure 3 As shown, the claw plate 950 can pass through the hole 940 of the operating plate 930 and extend between the rollers 920. The claw plate 950 can clamp the rollers 920 to prevent the rollers 920 from rotating. This allows the hanging basket 800 to be stably fixed at the preset position of the column 400, thereby reducing the pressure on the drive screw 700.
