Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine units, in particular to a lubricating grease smearing tool for the double-headed studs at the blade roots of wind turbine units. Background Technique

[0002] The double-headed studs for fixing the blades of existing wind turbines often break. After analysis, one of the important reasons is that the lubricating grease on the double-headed studs at the blade roots is not smeared according to the design specifications. The reason why the lubricating grease on the double-headed studs at the blade roots is not smeared according to the design specifications is that the current smearing of the lubricating grease on the double-headed studs at the blade roots completely relies on the skills and feel of the operators, and there is no tool to ensure that the smearing of the lubricating grease on the double-headed studs at the blade roots can be carried out according to the design requirements, ultimately resulting in the inability to carry out the standardized operation of smearing the lubricating grease on the double-headed studs at the blade roots according to the design requirements.

[0003] The authorized announcement number CN208944456U proposes a lubricating grease smearing tool for the double-headed studs at the blade roots of wind turbine units, including a base and a brush. The base is provided with a smearing cavity, the brush is detachably installed on the base, and the bristles of the brush are located in the smearing cavity. The smearing cavity is provided with an insertion hole for the double-headed studs at the blade roots to be inserted, and the bristles can contact the double-headed studs at the blade roots.

[0004] This device only sets a row of brushes for smearing work. To completely smear the double-headed studs, it is necessary to control the rotation of the device. During the rotation, it is impossible to ensure that the device always rotates around the center of the circle, resulting in uneven smearing of the lubricating grease on the double-headed studs. For this reason, we propose a lubricating grease smearing tool for the double-headed studs at the blade roots of wind turbine units. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a lubricating grease smearing tool for the double-headed studs at the blade roots of wind turbine units, which can control the brush to rotate along the center of the double-headed studs for uniform smearing, and can smear multiple double-headed studs at the blade roots according to the actual situation, effectively solving the problems in the background technique.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wind turbine blade root stud grease application tool, comprising a movable arc plate, a slide groove is provided on the right side surface of the movable arc plate, a slider is slidably connected inside the slide groove, the right side surface of the slider is fixedly connected to the left end of the screw, the right end of the screw is rotatably connected to a barrel, the right side surface of the barrel comprises slots at equal angles, four slots are respectively clamped with clamping plates, the inward side surface of each clamping plate is respectively fixedly connected to a brush, the left part of the barrel is connected to a control mechanism, the control mechanism comprises two sliding guide rails, the upper side arc surface of the movable arc plate is slidably connected to a movable plate by connecting to the two sliding guide rails, the right side surface of the movable plate is fixedly connected to an arc rack, and the arc rack is meshed with a gear one fixedly connected to the left part of the barrel.

[0007] A freely rotatable barrel is designed, so that the brush can be controlled to rotate along the center of the stud to apply the grease, so that the grease can be applied more evenly. A slide groove is designed, so that a splicable design is adopted, so that the number of barrels can be increased according to actual conditions, so that grease can be applied to multiple studs at the same time, thereby increasing efficiency. A sliding slider is designed, so that the position of the barrel can be adjusted easily, which is convenient for subsequent application work. When the control device is working, the slider is first moved by hand to slide the barrel to a suitable position, and then the movable arc plate is driven to move to the right, so that the stud is inserted into the barrel and contacts the brush, and then the barrel is driven to rotate through the control mechanism, so that the grease on the brush is evenly applied to the surface of the stud. When multiple studs are carried out at the same time, the slider at the left end of the added barrel is sequentially placed in the slide groove and adjusted to a suitable position. When the control mechanism is operated, the movable plate is driven to slide downward, thereby driving the gear to rotate through the arc rack, thereby driving the barrel to rotate.

[0008] Furthermore, the coating tool also includes a sliding guide rail 1, and the lower surface of the movable arc plate is slidably connected to the upper surface of the arc plate through the sliding guide rail 1.

[0009] The arc plate is designed so that it is close to the blade root, thereby facilitating positioning work, and a sliding guide rail is designed so as to limit the movement of the movable arc plate and avoid the movable arc plate from deflecting.

[0010] Furthermore, the coating tool also includes a clamping plate, which is arranged on the screw rod, and the clamping plate is threadedly connected to the screw rod through the opened screw hole.

[0011] When the position of the barrel is determined, the clamp is twisted so that the clamp is pressed against the surface of the movable arc plate to complete the fixation.

[0012] The coating tool further includes a handle, and the upper surface of the movable plate is fixedly connected to the handle.

[0013] The handle is designed to facilitate the control of the movable plate.

The control mechanism includes a sliding guide rail two 11. The upper arc surface of the moving arc plate 3 is slidably connected with a movable plate 12 through the sliding guide rail two 11. The right surface of the movable plate 12 is fixedly connected with an arc-shaped rack 13. The arc-shaped rack 13 meshes with a gear one 10 fixedly connected to the left part of the drum 7.

[0027] A rotatable drum 7 is designed so that the brush 9 can be controlled to rotate along the center of the double-headed stud for the application work, so that the lubricating grease is applied more evenly. A chute is designed, and a splicing design is adopted, so that the number of drums 7 can be increased according to the actual situation, so that the lubricating grease application work can be carried out on multiple double-headed studs at the same time, thus increasing the efficiency. A slidable slider 4 is designed, so that the position of the drum 7 can be easily adjusted, which is convenient for the subsequent application work. When the control device works, first slide the slider 4 by hand, so that the drum 7 slides to a suitable position, then drive the moving arc plate 3 to move to the right, so that the double-headed stud is inserted into the drum 7 and contacts the brush 9, and then drive the drum 7 to rotate through the control mechanism, so that the lubricating grease on the brush 9 is evenly applied to the surface of the double-headed stud. When multiple double-headed studs are carried out at the same time, the sliders 4 at the left ends of the increased drums 7 are sequentially placed in the chute and adjusted to a suitable position. When the control mechanism is controlled to work, drive the movable plate 12 to slide downward, so as to drive the gear one 10 to rotate through the arc-shaped rack 13, and then drive the drum 7 to rotate.

[0028] The application tool further includes a sliding guide rail one 2. The lower surface of the moving arc plate 3 is slidably connected with the upper surface of an arc-shaped plate 1 through the sliding guide rail one 2.

[0029] An arc-shaped plate 1 is designed to closely adhere the arc-shaped plate 1 to the blade root, which is convenient for the positioning work. A sliding guide rail one 2 is designed to limit the movement of the moving arc plate 3 and prevent the moving arc plate 3 from shifting.

[0030] The application tool further includes a clamping plate 6. The clamping plate 6 is arranged on the screw rod 5. The clamping plate 6 is threadedly connected with the screw rod 5 through a threaded hole opened.

[0031] After the position of the drum 7 is determined, turn the clamping plate 6 so that the clamping plate 6 abuts against the surface of the moving arc plate 3, thus completing the fixation.

[0034] The working principle of a grease smearing tooling for the double-headed stud at the blade root of a wind turbine unit provided by the present utility model is as follows:

[0035] First, press the arc-shaped plate 1 against the blade root, then manually move the slider 4 to make the round barrel 7 slide to a proper position. After the position of the round barrel 7 is determined, turn the clamping plate 6 to make the clamping plate 6 press against the surface of the movable arc plate 3 to complete the fixation. Then drive the movable arc plate 3 to move rightward to insert the double-headed stud into contact with the brush 9 on the round barrel 7. Then move the handle 14 to drive the movable plate 12 to slide downward, drive the first gear 10 to rotate through the arc-shaped rack 13, drive the round barrel 7 to rotate, and evenly smear the grease on the brush 9 onto the surface of the double-headed stud.
