[0001] The present application relates to the technical field of paint spraying protection tooling, and more particularly to a paint spraying protection tooling, a flange paint spraying device and a yaw variable pitch gearbox processing system. BACKGROUND

[0002] In a wind turbine generator set, the installation flange bolt holes and bolt installation positions of a yaw variable pitch gearbox are not painted, and protection is needed during overall painting to ensure that the bolt holes and installation positions are free of paint (topcoat) and that the bolts will not loosen due to residual paint after being tightened. Since the yaw variable pitch gearbox needs to be painted overall for corrosion protection, protection of non-painted parts is particularly important.

[0003] The existing protection for bolt holes and bolt installation positions uses plugs that cannot completely seal the bolt holes and are not tightly in contact with the flange surface, which can easily cause appearance quality problems such as color matching.

[0004] Therefore, it is necessary to provide a new technical solution to solve the technical problem that the existing plugs cannot effectively protect the bolt holes and bolt installation positions. UTILITY MODEL CONTENT

[0029] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Thus, other examples of the exemplary embodiments can have different values.

[0030] It should be noted that like reference numerals and letters refer to like items throughout the several views, and as such, further discussion of them need not be repeated in the subsequent views.

[0031] According to one embodiment of the present application, a paint spraying protection tool is provided for a flange body 4, the paint spraying protection tool comprising a mounting portion 1 and a protection portion 2, the mounting portion 1 being connected with the protection portion 2, the protection portion 2 having a first end 21, the mounting portion 1 being arranged at the first end 21, the diameter size of the first end 21 being greater than the diameter size of the mounting portion 1; wherein the mounting portion 1 and the protection portion 2 are both made of elastic material, the diameter size of the mounting portion 1 being greater than the size of a mounting hole 41 of the flange body 4 when the paint spraying protection tool is in an unconnected state with the flange body 4, the mounting portion 1 being embedded in the flange body 4 when the paint spraying protection tool is in a connected state with the flange body 4, the first end 21 being in contact with the surface of the flange body 4.

[0032] As shown in Figures 1 to 3 , the paint spraying protection device is used to protect the screw hole on the flange body 4. When the flange is treated by paint spraying for rust prevention, the mounting portion 1 of the paint spraying protection device is embedded in the screw hole. By blocking the mounting hole 41 on the flange body 4 with the mounting portion 1, the mounting hole 41 can be a screw hole, which avoids paint being sprayed into the screw hole during the paint spraying process, thereby affecting the fastening effect of the flange in subsequent use.

[0033] As shown in Figure 1 and Figure 2 , the mounting portion 1 is in a columnar shape, and the protection portion 2 is in a conical shape. The top end of the mounting portion 1 is connected with the bottom end of the protection portion 2, and the mounting portion 1 is located at the center of the bottom end of the protection portion 2. The mounting portion 1 and the protection portion 2 can be connected by bonding, interference fit or one-piece forming.

[0034] The first end 21 of the protection portion 2 is a bottom end face, which is one end of the conical structure with a large diameter size. The diameter size of the first end 21 is greater than the diameter size of the mounting portion 1, so that when the mounting portion 1 is embedded in the screw hole, the first end 21 is in contact with the surface of the flange body 4, covering the edge around the screw hole, thereby avoiding the edge of the flange body 4 close to the screw hole being sprayed with paint during the paint spraying treatment process, which affects the fastening of the subsequent screw and screw hole connection.

[0035] The mounting portion 1 and the protection portion 2 are both made of elastic material, for example, the elastic material is rubber, silicone or the like. The paint spraying protection tool made of elastic material can be interference fit with the screw hole by the deformable property of the elastic material, which will not cause wear or support to the screw hole of the flange body 4, thereby reducing the damage degree of the flange body 4. Moreover, the paint spraying protection tool made of elastic material can also adapt to the flange body 4 with different inner diameter sizes of screw holes by the deformable property, thereby effectively improving the adaptability of the paint spraying protection tool.

[0036] Of course, the paint spraying protection tool in the embodiments of the present application is not limited to the above structure and material, and those skilled in the art can set it according to actual needs.

[0037] In the embodiments of the present application, the mounting portion 1 made of elastic material is embedded in the mounting hole 41 of the flange body 4, so that the mounting portion 1 seals the mounting hole 41. The first end 21 of the protection portion 2 is set to be larger in diameter than the mounting portion 1, so that the protection portion 2 covers the surface of the flange body 4 at the edge of the screw hole, effectively avoiding paint spraying on the mounting hole 41 and the surface area of the flange body 4 centered on the mounting hole 41, so as to facilitate the connection with the fastener in the subsequent flange body 4 connection process, and avoid the influence of paint spraying on the connection strength of the flange body 4 in the subsequent use process.

[0038] In one example, the protection portion 2 has a second end 22 opposite to the first end 21, and the diameter of the protection portion 2 gradually decreases from the first end 21 to the second end 22.

[0039] As shown in Figure 1 and Figure 2 , the second end 22 of the protection portion 2 is a top end face, which is a small-diameter end of the conical protection portion 2. When the paint spraying protection tool is connected with the flange body 4, the bottom of the protection portion 2 is attached to the surface of the flange body 4, and the axis of the conical protection portion 2 is the same as the axis of the mounting hole 41. That is, the conical protection portion 2 covers the surface of the flange body 4 centered on the mounting hole 41, so that the flange body 4 has a connection surface reserved for the bolt cap during the paint spraying and rust prevention process, preventing paint from being sprayed on the area of the flange body 4, which affects the connection strength of the fastener such as a bolt with the flange body 4.

[0040] The side of the protection portion 2 away from the flange body 4 is set to be conical, so that the paint sprayed on the protection portion 2 is easy to clean, and the paint sprayed on the protection portion 2 is easy to clean because the paint spraying protection tool is made of elastic material, so as to facilitate the reuse of the paint spraying protection tool, improve the practicability of the paint spraying protection tool, and reduce the plugging cost of the flange body 4 during rust removal.

[0041] In one example, the paint spraying protection tool further comprises a holding portion 3, which is arranged at the second end 22, and the holding portion 3, the protection portion 2 and the mounting portion 1 are integrally formed.

[0042] As shown in Figure 1 and Figure 2As shown in the figures, the holding part 3 is arranged at the second end 22 of the conical protective part 2, that is, the bottom of the holding part 3 is connected with the top of the protective part 2. The holding part 3 and the protective part 2 can be connected by adhesion, interference fit or one-piece forming.

[0043] By arranging the holding part 3 at the top of the protective part 2, the paint spraying protective tool can be conveniently taken, installed and / or disassembled.

[0044] In one example, the holding part 3 comprises a holding end 31 and an extension segment 32, the opposite ends of the extension segment 32 are respectively connected with the second end 22 and the holding end 31, the diameter of the extension segment 32 is the same as the diameter of the second end 22, and the diameter of the extension segment 32 is smaller than the diameter of the holding end 31.

[0045] As shown in the figures, Figure 1 and Figure 2 the holding part 3 comprises a holding end 31 and an extension segment 32. The holding end 31 and the extension segment 32 are both columnar structures. By setting the diameter of the holding end 31 to be larger than the diameter of the extension segment 32, the holding end 31 can be conveniently held to install and / or disassemble the paint spraying protective tool.

[0046] Of course, the holding end 31 and the extension segment 32 in the embodiments of the present application are not limited to the above structures, and those skilled in the art can set them according to actual needs. For example, the holding end 31 and the extension segment 32 can have the same diameter, the holding end 31 and the extension segment 32 can be plate-shaped structures, or the holding end 31 can be plate-shaped and the extension segment 32 can be columnar.

[0047] In one example, the mounting part 1, one end of the extension segment 32 close to the holding part 3 and the holding part 3 are all chamfered.

[0048] As shown in the figures, Figure 1 and Figure 2 the mounting part 1 is cylindrical, and the edges of the top and bottom of the mounting part 1 are all chamfered. This not only facilitates the embedding of the mounting part 1 into the mounting hole 41, but also facilitates the close fitting of the mounting part 1 to the inner wall of the mounting hole 41 in the embedded state, so as to seal the mounting hole 41 and prevent paint from being sprayed into the mounting hole 41.

[0049] The holding part 3 is columnar, and the edges of the top and bottom of the holding part 3 are all chamfered. This not only improves the comfort when holding the paint spraying protective tool, but also facilitates the removal of paint sprayed on the paint spraying protective tool.

[0050] One end of the extension segment 32 close to the holding part 3 is chamfered, which improves the connection and transition of the extension segment 32 and the holding part 3, avoids dead angles and reduces the difficulty of paint removal.

[0051] According to another embodiment of this application, a flange painting apparatus is provided, which includes the flange body 4 and the painting protective fixture as described above.

[0052] like Figure 3 As shown, this paint protection fixture is used to seal the mounting hole 41 on the flange body 4. The flange body 4 requires rust prevention treatment before use, which is achieved by spraying paint onto its surface. This paint protection fixture is installed at the mounting hole 41 of the flange body 4 to prevent paint from being applied to the mounting hole 41 and the nut connection area centered on the mounting hole 41, thus avoiding any impact on the connection strength between the screws and other fasteners and the flange body 4.

[0053] In one example, the flange body 4 has a mounting hole 41, and when the paint protection fixture is not connected to the flange body 4, the size of the mounting hole 41 is smaller than the size of the mounting part 1.

[0054] like Figure 3 As shown, the flange body 4 has a mounting hole 41, which can be a screw hole.

[0055] The mounting part 1 is made of elastic material. When the paint protection fixture is not connected to the flange body 4, the diameter of the mounting part 1 is larger than the diameter of the mounting hole 41. When the paint protection fixture is connected to the flange body 4, the mounting part 1 is embedded in the mounting hole 41, and the outer circumferential surface of the mounting part 1 abuts against the inner wall of the mounting hole 41 to seal the mounting hole 41.

[0056] According to another embodiment of this application, a yaw and pitch gearbox processing system is provided. The yaw and pitch gearbox processing system includes a housing and a flange painting device as described above. The flange body 4 is disposed in the housing. When the flange body is painted, the mounting part 1 is embedded in the mounting hole 41, and the first end 21 is in contact with the surface of the flange body 4.

[0057] like Figure 3 As shown, the flange body 4 is used in a yaw and pitch gearbox machining system. The yaw and pitch gearbox is equipped with a flange painting device. Before use, the flange body 4 requires rust prevention treatment, which is achieved by spraying paint onto its surface. A protective painting fixture is installed at the mounting holes 41 of the flange body 4 to prevent paint from being applied to the mounting holes 41 and the nut connection area centered on the mounting holes 41, thus avoiding any impact on the connection strength between the screws and other fasteners and the flange body 4.

[0058] In one example, the diameter of the mounting portion 1 is greater than the diameter of the mounting hole 41 when the paint protection assembly and the flange are in the unconnected state, and the outer circumferential surface of the mounting portion 1 abuts the inner wall of the mounting hole 41 when the paint protection assembly and the flange are in the connected state.

[0059] As shown in Figure 3 The flange body 4 has a mounting hole 41, which can be a threaded hole. The mounting portion 1 is made of an elastic material, and the diameter of the mounting portion 1 is greater than the diameter of the mounting hole 41 when the paint protection assembly is not connected to the flange body 4. In the connected state, the mounting portion 1 is embedded in the mounting hole 41, and the outer circumferential surface of the mounting portion 1 abuts the inner wall of the mounting hole 41 to seal the mounting hole 41.

[0060] Although some specific embodiments of the present application have been described in detail by way of example with reference to the drawings, it is to be understood that the above examples are intended to be illustrative only and are not intended to limit the scope of the present application. It is to be understood that modifications of the above embodiments can be made without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
