Description

Technical fields:

[0001] This utility model relates to the field of wind turbine tower manufacturing technology, and specifically discloses a flange spraying protective sticker fixing tool. Background technology:

[0002] After the wind turbine towers are manufactured, they need to be painted for corrosion protection. The tower sections are connected by flanges and bolts. Many engine manufacturers require that the flange ends not be painted (or that the flange connection bolt gaskets not be painted), and only zinc spraying is required. Therefore, during tower manufacturing, masking paper must be used to protect the areas that do not need to be painted before painting, and the flange ends must be completely wrapped for protection.

[0003] However, due to the high pressure during the paint spraying process, coupled with cold weather, the outer wall of the tower will be slightly covered with condensation, which will reduce the adhesion of the masking sticker. The sticker will then lift up during the spraying process and will not be able to protect the flange end face well. Utility Model Content:

[0004] The purpose of this utility model is to provide a flange spray paint protective sticker fixing tool to solve the problems existing in the prior art.

[0005] This utility model is implemented by the following technical solution: a flange spray paint protective sticker fixing fixture, including a base plate, connecting lugs, magnets and connecting pins. Two connecting lugs are symmetrically arranged on both sides of the base plate. One connecting lug of each of the two base plates overlaps. The two overlapping connecting lugs are provided with connecting pins. A positioning groove is opened on the base plate, and a magnet is placed in the positioning groove.

[0006] Furthermore, the connecting pin includes a lower half and an upper half. The bottom of the pin body in the lower half is integrally formed with a first flange, and a threaded hole is provided at the top of the pin body in the lower half. The upper half is provided with a stud that is threadedly connected to the threaded hole, and a second flange is integrally formed at the top of the stud.

[0007] Furthermore, it also includes a handle, which is fixedly installed on the base plate.

[0008] The advantages of this utility model are: the base plates are hinged to each other by connecting lugs, which can adapt to flange end faces of various sizes. The appropriate number of base plates can be spliced ​​according to the size of the flange to cover the entire end face. The base plates and the stickers used for masking are tightly attached to the flange end face by magnets. At the same time, the base plates can increase the area for pressing the stickers, so that the stickers are pressed tightly during the entire painting process, and the stickers will not easily fall off.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] like Figure 1 , Figure 2 As shown: A flange spray painting protective sticker fixing fixture includes a base plate 1, connecting lugs 2, magnets 3, and connecting pins 4. Two connecting lugs 2 are symmetrically arranged on both sides of the base plate 1. One connecting lug 2 of each of the two base plates 1 overlaps, and the connecting pins 4 pass through the two overlapping connecting lugs 2. A positioning groove 101 is opened on the base plate 1, and a magnet 3 is placed in the positioning groove 101. In use, multiple base plates 1 are connected to each other through the lugs 2. Two adjacent lugs 2 overlap and are connected by connecting pins 4 passing through them. The angle of adjacent base plates 1 can be adjusted arbitrarily. The number of base plates 1 is set according to the area of ​​the flange end face, and the angle between the base plates 1 is adjusted. The base plates 1 are connected around the flange end face. Then, the magnets 3 are placed in the positioning groove 101 to fix the base plate 1 and the protective sticker to the end face of the flange to be covered. After spraying, the magnets 3 are removed one by one to separate the base plate 1 from the flange end face.

[0014] The connecting pin 4 includes a lower half 401 and an upper half 402. The bottom of the pin body of the lower half 401 is integrally formed with a first flange 4011, and a threaded hole 4012 is formed at the top of the pin body of the lower half 401. The upper half 402 is provided with a stud 4021 that is threadedly connected to the threaded hole 4012, and a second flange 4022 is integrally formed at the top of the stud 4021. In use, the lower half 401 is first placed at the bottom of the earring 2, and the pin body of the lower half 401 is inserted through the two overlapping pieces. Inside the earring 2, the inner edge of the earring 2 matches the shape of the outer periphery of the lower half 401 pin. The lower half 401 pin acts as a hinge axis, allowing the two earrings 2 to be adjusted in angle. The lower half 401 pin can slide freely back and forth on the inner edge of the earring 2. After the upper half 402 is threadedly connected to the lower half 401, the first flange 4011 and the second flange 4022 respectively clamp the two stacked earrings 2 in the middle, so that when adjusting each base plate 1, the connecting pin 4 is fixed on the two earrings 2. In addition, for ease of use and adjustment, a handle 5 is fixedly installed on the base plate 1. Since the base plate 1 is in close contact with the flange end face, and the thickness of the base plate 1 needs to be relatively thin to ensure the attraction force of the magnet 3, it is inconvenient to operate when taking it out and adjusting it. The handle 5 makes it convenient to take it out and adjust its position.

[0015] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "front", "rear", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
