Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to an auxiliary structure for facilitating the maintenance of fans. Background Art

[0002] Fans may develop various faults after long-term use. Maintenance is to repair the faults and restore the normal operation of the fan. Through maintenance, damaged or failed parts can be replaced, and necessary repairs, adjustments or calibrations can be made to ensure that the performance and function of the fan are restored to the expected level.

[0003] A search revealed a refrigeration fan repair device with patent publication number CN221836581U that states, "When in use, the bidirectional motor is started, which drives the reel to rotate, causing the connecting rope to descend to a suitable position. The hook is then hung on the hanging ring. The bidirectional motor is then started again to reverse, causing the reel to reel in the connecting rope. This allows the fan body to be lifted for easy maintenance. The moving assembly then facilitates moving the repaired fan body to a suitable position. The stabilizing assembly then clamps the fan body when it is lifted, preventing it from shaking and increasing stability during maintenance."

[0004] However, the above solution still has certain shortcomings in actual use. In the above solution, the clamping process of the fan requires manual rotation of the screw, so that the screw drives the clamping plate to clamp the side end of the fan, resulting in the need for manual auxiliary clamping throughout the clamping process. Manual operation is time-consuming and labor-intensive, which greatly reduces the efficiency of the fan maintenance work. Utility Model Content

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.

[0022] See also Figure 1-4 The utility model discloses an auxiliary structure for facilitating wind turbine maintenance, including a movable base 1. The top of the movable base 1 is provided with a driving device 2, a lifting device 3 and a fixed structure 4, and the fixed structure 4 is located above the lifting device 3.

[0023] The driving device 2 includes a linear motor 201, a movable end of the linear motor 201 is provided with a moving platform 202, and a conveying frame 203 is fixedly installed on the top of the moving platform 202;

[0024] The lifting device 3 includes a driving box 301, the top of which is movably connected to a top cover 302, the inner wall of which is rotatably connected to a double-headed screw 303 by a built-in motor, the top of which is provided with an electric push rod 304, the surface of which is provided with two sections of teeth in opposite directions, the surface of which is threadedly connected to a threaded block, the top of which is fixedly installed to the bottom of the electric push rod 304, and the movable end of the electric push rod 304 is fixedly connected to a lifting plate 305;

[0025] The fixed structure 4 includes a brake box 401, and a dual-axis motor 402 is fixedly installed on the inner wall of the brake box 401. The output shaft of the dual-axis motor 402 is fixedly installed with a rotating shaft 403. The surface of the rotating shaft 403 is provided with a guide rod 404, and the surface of the rotating shaft 403 is provided with an arc groove. The inner wall of the brake box 401 is fixedly installed with a sliding rod, the back end of the guide rod 404 overlaps with the opening of the arc groove, the inner wall of the guide rod 404 is slidably connected to the surface of the sliding rod, and the bottom end of the guide rod 404 is provided with a pulling rope 405, and the bottom end of the pulling rope 405 is wrapped with a fixing plate 406.

[0026] By setting up a driving device 2, a lifting device 3 and a fixing structure 4, the driving device 2 can be used to transfer the fan to the top of the lifting device 3, so that the lifting device 3 can assist in clamping the bottom end of the fan, and then cooperate with the fixing structure 4 to assist in fixing the lifted fan, so that the fan can be adjusted in height while being clamped, and the entire clamping process adopts mechanized operation, avoiding the time-consuming and labor-intensive manual operation, thereby improving the maintenance efficiency of the fan.

[0027] Specifically, a hollow groove 204 is opened inside the conveying frame 203 , and the specification of the hollow groove 204 is greater than the total length between the two lifting plates 305 .

[0028] In this embodiment, the lifting plate 305 can penetrate the hollow slot 204 and assist in lifting the blower on the conveying rack 203 , thereby ensuring the lifting effect of the lifting plate 305 .

[0029] Specifically, a cross bar 306 is slidably connected between the two fixing plates 406 and between the two lifting plates 305 .

[0030] In this embodiment, the cross bar 306 can be used to significantly improve the mutual sliding effect between the two fixed plates 406 and between the two lifting plates 305.

[0031] When in use, the fan to be repaired is first placed on the conveyor frame 203, and then the linear motor 201 is started, so that the linear motor 201 starts to drive the movable platform 202 to slide inside the movable base 1, prompting the movable base 1 to drive the fan through the conveyor frame 203 to gradually move to the top of the lifting device 3;

[0032] Then, the driving motor inside the driving box 301 is started, so that the driving motor drives the double-headed screw 303 to rotate. Since the surface of the double-headed screw 303 is provided with two sections of thread teeth in opposite directions, and the thread grooves provided inside the thread block are misaligned with the thread teeth, the thread block slides along the surface of the double-headed screw 303, and the movement directions of the two thread blocks are opposite, so that the two thread blocks drive the two lifting plates 305 to move toward or away from each other through the electric push rod 304, so that the two lifting plates 305 move closer to or farther away from each other, so that the interval between the two lifting plates 305 can be adaptively adjusted according to the width of the fan;

[0033] After the fan is positioned above the lifting plate 305, so that the lifting plate 305 is now directly below the hollow slot 204, the electric push rod 304 is activated to lift the lifting plate 305 upward, causing the lifting plate 305 to pass through the hollow slot 204 and contact the bottom end of the fan, so that the electric push rod 304 drives the fan to gradually lift up through the lifting plate 305;

[0034] Then, the fixed structure 4 is started, so that the movable end of the dual-axis motor 402 starts to drive the rotating shaft 403 to rotate, causing the opening of the arc groove provided on the surface of the rotating shaft 403 to move. The movement of the arc groove opening drives the guide rod 404 to slide along the direction of the arc groove opening, causing the guide rod 404 to move laterally along the direction of the sliding rod, so that the guide rod 404 drives the fixed plate 406 to slide synchronously through the pulling rope 405;

[0035] Since the openings of the arc grooves formed on the surfaces of the two rotating shafts 403 are in opposite directions, the movement directions of the two guide rods 404 are opposite, so that the two guide rods 404 can drive the two fixing plates 406 to move toward or away from each other, so that the distance between the two fixing plates 406 can be adaptively adjusted according to the width of the fan;

[0036] As the lifting plate 305 drives the fan to gradually rise, the top of the fan will eventually contact the fixed plate 406, so that the top of the lifting plate 305 and the bottom of the fixed plate 406 are plugged into each other, causing the fan to be clamped between the lifting plate 305 and the fixed plate 406, so that the fan is clamped in the air.

[0037] To sum up, the auxiliary structure for facilitating fan maintenance is provided with a driving device 2, a lifting device 3 and a fixing structure 4. The driving device 2 can be used to transfer the fan to the top of the lifting device 3, so that the lifting device 3 can assist in clamping the bottom end of the fan, and then cooperate with the fixing structure 4 to assist in fixing the fan after lifting, so that the fan can be height-adjusted while being clamped, and the entire clamping process adopts mechanized operation, avoiding the time-consuming and labor-intensive manual operation, thereby improving the maintenance efficiency of the fan.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
