Description

Technical Field

[0001] This application relates to rust removal technology for wind turbine tower blanks, and more particularly to a rust removal device for wind turbine tower blanks. Background Technology

[0002] Wind turbine towers are made from steel plate blanks with a thickness of 100mm-150mm. In order to ensure that the welding on the sides of the steel plate after rolling is safe and up to standard, the sides of the steel plate blank need to be ground and rusted before rolling.

[0003] The current rust removal process involves using an angle grinder with a rust-removing brush attached, and then manually holding the grinder to grind and remove rust along the side of the steel plate. However, the vibrations generated by manually holding the angle grinder in this process make rust removal inefficient and laborious. Furthermore, it is difficult for the operator to maintain a continuous contact between the rust-removing brush and the side of the steel plate, affecting the rust removal effect. Utility Model Content

[0004] This application provides a rust removal device for wind turbine tower blanks, which solves the problem of difficult and laborious operation in the existing manual rust removal of steel plates by holding an angle grinder, thus affecting the rust removal effect.

[0005] This application provides a rust removal device for wind turbine tower blanks, including a positioning plate, a rust removal mechanism, and a driving mechanism. The rust removal mechanism is provided on one side of the positioning plate. The rust removal mechanism consists of two sets of roller brushes and disc brushes. Each set of roller brushes and disc brushes is sleeved and fixed on a rotating shaft. One end of the rotating shaft passes through to the other side of the positioning plate and is rotatably connected. A fixing frame is fixed on the other side of the positioning plate. The driving mechanism is mounted on the fixing frame and is connected to the rotating shaft for transmission. The disc brush is located between the roller brushes and the positioning plate, and its diameter is larger than that of the roller brushes.

[0006] Optionally, the drive mechanism includes a motor mounted on a fixed frame, a driven gear fixed at one end of the rotating shaft located on the fixed frame, and a driving gear meshing with the driven gear fixed on the output shaft of the motor.

[0007] Optionally, the two ends of the positioning plate are respectively hinged with wheel frames for pressing the roller brush onto the steel plate, and the wheel frames are rotatably connected to guide wheels on one side of the roller brush.

[0008] Optionally, the wheel frame is a telescopic rod that can automatically retract, pressing the roller brush against the steel plate through the tension of automatic retraction.

[0009] Optionally, a spring is fixed between the positioning plate and the wheel frame, and the spring force presses the roller brush onto the steel plate.

[0010] Optionally, two mirror-symmetrical positioning plates and a rust removal mechanism are provided. The rust removal mechanisms on the two positioning plates clamp the edges of the steel plate from opposite sides. The two positioning plates are connected by a tie rod and can be tightened towards the center. The tie rod is detachably connected to the connecting piece fixed on the positioning plate.

[0011] Compared with the prior art, the beneficial effects of the rust removal device for wind turbine tower blanks provided in this application are:

[0012] By using an inclined positioning plate, two roller brushes are clamped on the upper and lower surfaces of the steel plate edge, ensuring the brushes are in close contact with the side of the steel plate. The roller brushes can then be used to grind and remove rust from both sides of the steel plate edge, widening the welding space at the joint, facilitating welding operations, and improving welding results.

[0013] Meanwhile, the clamping of the steel plate between the two roller brushes on both the top and bottom surfaces makes the grinding of the steel plate's sides more stable and easier for the operator to control and move. The roller brushes also maintain continuous contact with the sides of the steel plate, resulting in better rust removal. The reciprocating grinding of the steel plate's sides by the two roller brushes simultaneously also improves the efficiency of rust removal. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0023] like Figures 1-4 As shown, one embodiment of this application provides a rust removal device for wind turbine tower blanks, including a positioning plate 1, a rust removal mechanism, and a driving mechanism. The rust removal mechanism is provided on one side of the positioning plate 1. The rust removal mechanism consists of two sets of roller brushes 7 and disc brushes 8. Each set of roller brushes 7 and disc brushes 8 is sleeved and fixed on a rotating shaft 3. One end of the rotating shaft 3 passes through to the other side of the positioning plate 1 and is rotatably connected. A fixing frame 2 is fixed on the other side of the positioning plate 1. The driving mechanism is mounted on the fixing frame 2 and is connected to the rotating shaft 3 for transmission. The disc brushes 8 are located between the roller brushes 7 and the positioning plate 1, and their diameter is larger than that of the roller brushes 7.

[0024] In use, hold the fixing frame 2 and clamp the two roller brushes 7 on the positioning plate 1 onto the upper and lower surfaces of one side edge of the steel plate 13, so that the disc brush 8 is in contact with the side edge of the steel plate 13. Start the drive mechanism to make the rotating shaft 3 drive the roller brushes 7 and disc brushes 8 to rotate. The moving device along the edge of the steel plate 13 allows the two roller brushes 7 to grind and remove rust from the upper and lower surfaces of the edge of the steel plate 13, while the two disc brushes 8 grind and remove rust from the side edge of the steel plate 13 in turn.

[0025] In this embodiment, two roller brushes 7 are clamped on the upper and lower surfaces of the edge of the steel plate 13 by means of an inclined positioning plate 1, and the disc brush 8 is made to fit against the side of the steel plate 13. The roller brushes 7 can grind and remove rust from the upper and lower surfaces of the edge of the steel plate 13, widen the welding space at the joint, facilitate welding operations, and improve the welding effect.

[0026] Meanwhile, the clamping of the upper and lower surfaces of the steel plate 13 by the two roller brushes 7 makes the grinding of the side of the steel plate 13 by the disc brush 8 more stable and easier for the operator to control and move. The disc brush 8 can also maintain continuous contact with the side of the steel plate 13, resulting in better rust removal. The reciprocating grinding of the side of the steel plate 13 by the two disc brushes 8 at the same time also improves the efficiency of rust removal.

[0027] In one possible implementation, the drive mechanism includes a motor 5 mounted on a fixed frame 2, a driven gear 4 fixed at one end of the rotating shaft 3 located on the fixed frame 2, and a driving gear 6 meshing with the driven gear 4 fixed on the output shaft of the motor 5.

[0028] When the drive mechanism is started, the output shaft of the motor 5 drives the rotating shaft 3 to rotate through the meshing of the driving gear 6 and the driven gear 4. This causes the roller brush 7 and the disc brush 8 to rotate, grinding and removing rust from the upper and lower surfaces and sides of the steel plate 13.

[0029] In one possible implementation, the two ends of the positioning plate 1 are respectively hinged with wheel frames 9 for pressing the roller brush 7 onto the steel plate 13, and the wheel frames 9 are rotatably connected to guide wheels 10 on one side of the roller brush 7.

[0030] The tension generated by the wheel frame 9 allows the roller brush 7 to fit tightly against the steel plate 13, improving the polishing effect. The guide wheel 10 provides guidance as the rust removal device moves along the edge of the steel plate 13.

[0031] In one possible implementation, the wheel frame 9 is a telescopic rod that can automatically retract, pressing the roller brush 7 onto the steel plate 13 through the tension of automatic retraction.

[0032] The wheel frame 9 is a telescopic rod structure, with a tension spring installed inside that can automatically retract after being stretched. The guide wheel 10 presses the roller brush 7 against the steel plate 13 from the opposite side of the steel plate 13.

[0033] In one possible implementation, a spring is fixed between the positioning plate 1 and the wheel frame 9, and the roller brush 7 is pressed onto the steel plate 13 by the elastic force.

[0034] The spring is fixed at the angle between the positioning plate 1 and the wheel frame 9. After installation, the spring force causes the wheel frame 9 to rotate around the hinge, and the two guide wheels 10 move to both ends respectively, thereby pulling the positioning plate 1 to press the roller brush 7 and the steel plate 13 together.

[0035] like Figure 5 As shown, in one possible implementation, there are two mirror-symmetrical positioning plates 1 and a rust removal mechanism. The rust removal mechanisms on the two positioning plates 1 are respectively clamped on the edge of the steel plate 13 from opposite sides. The two positioning plates 1 are connected by a tie rod 11 and can be tightened towards the center. The tie rod 11 is detachably connected to the connecting piece 12 fixed on the positioning plate 1.

[0036] Two mirror-symmetrical positioning plates 1 and a rust removal mechanism are respectively clamped on opposite sides of the steel plate 13. The two mirror-symmetrical positioning plates 1 are connected and fixed by a tie rod 11. A tension spring is installed inside the tie rod 11, which can tighten the two opposite positioning plates 1 towards the center, so that the disc brush 8 fits better with the side of the steel plate 13, which not only increases the rust removal effect, but also improves the rust removal efficiency by polishing from both sides at the same time.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
