Under the action of the limit rod 42 and the limit groove, the screw sleeve 33 is lifted and lowered in the vertical direction, thereby driving the lifting plate 2 and the support frame 11 to lift and lower synchronously, so that the support frame 11 is transferred to the set height, thereby eliminating the need for the staff to manually climb the fan resistor body, saving the staff's workload, time and effort, facilitating the staff to maintain the fan resistor body, reducing safety hazards, and improving safety.

[0025] A lifting groove 21 is horizontally provided on the top of the lifting plate 2, and the lifting groove 21 is T-shaped. A baffle 22 is installed on the lifting plate 2.

At the same time, the first drive ring 61 and the second drive ring 62 are detachably connected, so that the staff can disassemble and replace the first drive ring 61 and the second drive ring 62 conveniently.

[0027] A transmission groove 12 is vertically opened on the side wall of the support frame 11, and an abutment plate 13 and a transmission plate 14 are installed on the side wall of the transmission groove 12.

The bottom of the transmission plate 14 is used to abut against the top of the abutment plate 13, so that when the transmission plate 14 is converted from a vertical setting to a horizontal setting, the abutment plate 13 abuts and supports the transmission plate 14 to limit the position, thereby improving the stability of the transmission plate 14. A transverse groove 15 is vertically opened on the top of the transmission plate 14, and a transmission member 8 is installed in the transverse groove 15.

The two sides of the horizontally arranged limiting plate 97 are respectively fixedly connected to the two vertical plates 95, and the bottom of the limiting plate 97 is fixedly connected to the horizontal plate 82. There are two vertically arranged connecting rods 92, each of which is located on one side of the connecting plate 91, and the connecting rod 92 is fixedly connected to the connecting plate 91, and the connecting rod 92 is away from the bottom of the support frame 11.

[0028] In order to expand the maintenance range of the staff, the staff adjusts the transmission plate 14 so that the transmission plate 14 is adjusted from a vertical setting to a horizontal setting, and the side wall of the transmission plate 14 abuts against the side wall of the abutment plate 13. At this time, the staff adjusts the transmission cylinder 81, and the piston rod of the transmission cylinder 81 is extended and retracted to drive the cross plate 82 to move synchronously, thereby adjusting the distance between the cross plate 82 and the transmission plate 14. At the same time, the cross plate 82 is extended and retracted to drive the cross bar 96 to move synchronously, so that the staff is transferred to the set position through the cross plate 82 to inspect the wind turbine body 1, and the staff uses the cross bar 96, the connecting rod 92 and the limit plate 97 to prevent the staff from falling from the cross plate 82, thereby improving safety.

[0029] The working principle of the present invention is as follows: When a wind turbine maintenance support that is conducive to safe maintenance of the present embodiment is in use, when the wind turbine body 1 needs to be maintained, the staff starts the lifting motor 31, and the output shaft of the lifting motor 31 rotates to drive the screw rod 32 to rotate synchronously, thereby driving the screw sleeve 33 to move synchronously, and through the limiting action of the limiting rod 42 and the supporting groove 51, the screw sleeve 33 is lifted and lowered in the vertical direction, thereby driving the lifting plate 2, the support frame 11, the first driving ring 61, the second driving ring 62 and the driving mechanism 7 to rise and fall synchronously until the support frame 11 is transferred to the set height, and the staff then starts the driving cylinder 71, and the piston rod of the driving cylinder 71 is extended and retracted to drive the support frame 11 to move along the length direction of the lifting groove 21, so that the support frame 11 is transferred to the set position, so as to facilitate the staff to maintain the wind turbine body 1, and at the same time, there is no need for the staff to manually climb the wind turbine body 1, which saves the staff's workload, saves time and effort, and improves safety.

[0030] In order to expand the maintenance range, the staff adjusts the transmission plate 14 from a vertical setting to a horizontal setting, and the bottom of the transmission plate 14 abuts against the top of the abutment plate 13 to increase the stability of the transmission plate 14. The staff then starts the transmission cylinder 81, and the piston rod of the transmission cylinder 81 is extended and retracted to drive the cross plate 82 to move synchronously, so that the vertical plate 95 and the cross bar 96 on the cross plate 82 move synchronously, so that the staff can expand the maintenance range through the cross plate 82. At the same time, through the limit plate 97, the cross bar 96 and the connecting rod 92, the staff can further improve safety during maintenance.
