Description

Technical Field

[0001] The utility model belongs to the field of wind power generation, in particular to a fan blade maintenance support device for wind power generation. Background Art

[0002] Wind turbines are environmentally friendly energy devices. Damaged blades can affect system efficiency and safety. Damaged blades can be inspected, repaired or replaced. When repairing or replacing, it is necessary to follow the manufacturer's requirements and standards to ensure the safety of operators and the normal operation of the entire system.

[0003] The fan blades are prone to damage during long-term operation. The main reasons are as follows: 1. Overload impact caused by strong winds and storms; 2. Damage caused by collision of loose machine parts or connectors; 3. Aging caused by long-term ultraviolet rays, wind erosion and pollen. Before starting blade maintenance, you first need to check the surface of the blade to see if there is damage such as wear and cracks on the blade. At the same time, you also need to check whether the blade surface coating is intact. If there is damage such as wear or cracks on the blade surface, it needs to be repaired. There are two main repair methods: filling reinforcement and repair reinforcement. Filling reinforcement is mainly for small cracks in the corners of the blades. Fill the filling material into the damaged part of the blade and reinforce and repair it; repair reinforcement is mainly for large-area damage to the blades. It needs to be repaired with fiberglass materials and composite materials. Due to the different flatness of the blade surface, when repairing and supporting the blade, due to the different heights of the last support points on the surface, different support structures need to be used for support, which increases the difficulty of supporting when repairing the fan blades.

[0004] In summary, the utility model therefore provides a fan blade maintenance support device for wind power generation to solve the above-mentioned problems. Utility Model Content

When the blade is repaired and supported, different support structures need to be used for support due to the different heights of the final support points on the surface, which increases the difficulty of supporting the fan blade when repairing the blade.

[0006] A fan blade maintenance support device for wind power generation comprises a support base, an adjusting platform is arranged above the support base, a hydraulic pump is installed on the surface of the support base, the output shaft of the hydraulic pump is fixedly connected to the bottom of the adjusting platform, the surface of the adjusting platform is vertically connected to two mutually symmetrical guide stretching rail plates, the surface of the guide stretching rail plate is slidably connected to a sliding rail plate, one end of the sliding rail plate is respectively fixedly connected to a bottom support plate and a side support plate, a trend gear is arranged between the two sliding rail plates, driving lifting scale plates are respectively arranged on both sides of the trend gear, the driving lifting scale plates are respectively connected to the sliding rail plates, the middle part of the trend gear is rotatably connected to a rotating shaft, a hydraulic rod push frame is installed on the rotating shaft, and the hydraulic rod push frame is connected to the adjusting platform through a hydraulic rod.

[0007] Furthermore, a track groove is provided on one side of the sliding track plate, and the guide stretching track plate is slidably inserted into the track groove and is arranged along the length direction of the sliding track plate.

[0008] Furthermore, the driving lifting ruler plates are respectively arranged along the length direction of the sliding track plate, and the trend gear and the driving lifting ruler plates are meshed with each other.

[0009] Furthermore, the hydraulic rod push frame is a "U"-shaped structure, and the inner walls on both sides of the hydraulic rod push frame close to the opening are respectively fixedly connected to the two ends of the rotating shaft.

[0010] Furthermore, one end of the hydraulic rod is mounted on the adjustment platform, and the other end is fixedly connected to an end of the hydraulic rod push frame away from the opening.

[0011] Furthermore, the guide stretching rail plate and the driving lifting ruler plate are respectively arranged on both sides of the sliding rail plate, and the sliding rail plate is fixedly connected to the driving lifting ruler plate.

[0012] Furthermore, the surface of the side support plate is provided with a concave groove, and the surface of the bottom support plate is a plane.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model sets a supporting base and an adjusting platform. The adjusting platform and the supporting base are raised and lowered by a hydraulic pump to adjust the height of the entire adjusting platform. The height of the two sliding track plates can be adjusted at the same time by a hydraulic rod. After the adjusting platform rises to a certain height, the hydraulic rod is used to provide more precise support at the bottom of the fan blade.

[0015] 2. The utility model sets a tendency gear to slide on the driving lifting scale plates on both sides. Since the size of the fan blades is different from the fan tail to the fan head, the sliding track plates on both sides can be individually controlled to rise and fall by driving the lifting scale plate, so that the side support plates and the bottom support plates can be lifted and lowered to different heights, and the fan blades can be stably supported to different degrees, avoiding the need for multiple points of support during the fan blade support process and excessive increase of support structure. The device can control the support at two positions at the same time, stably supporting the fan blades at different positions at the bottom, and adjusting according to the horizontal height of the bottom surface of the fan blades, so as to facilitate the support and fixation of the fan blades.
