Description

Technical Field

[0001] The utility model relates to the technical field of spray hangers, in particular to an electrostatic spray hanger with high uniformity on the surface of elastic strips. Background Art

[0002] Spring clips are crucial components in railway fasteners. Due to their exposed environment, spring clips installed on the track are prone to rust, making surface corrosion protection crucial. Numerous methods exist for protecting spring clips from corrosion. For electrostatically sprayed spring clips, the uniformity of the coating significantly impacts their corrosion resistance. Current hangers for electrostatic spraying compromise coating uniformity due to the interlocking of the spring clips. Furthermore, the contact area between the spring clip and the hook is too large, preventing spraying. Therefore, a new hanger is needed to address this issue.

[0003] According to the Chinese patent announcement number: CN207371746U, a spray hanger includes a main pole and an anti-slip hanging rod. The anti-slip hanging rod is H-shaped, the middle part of the anti-slip hanging rod is fixed on the main pole, and the end of the anti-slip hanging rod has a hanging piece. A number of supporting bars and anti-slip hanging rods are arranged in sequence from bottom to top along the length direction of the main pole, wherein the supporting bar is I-shaped, the supporting bar is arranged parallel to the anti-slip hanging rod, the middle part of the supporting bar is fixed on the main pole, and the end of the supporting bar and the hanging pieces on both sides of the anti-slip hanging rod respectively form support for the product.

[0004] In the above solution, the middle portion of the support bar is fixed to the main bar, and the ends of the support bar and the two side hanging pieces on the anti-slip hanging bar respectively form support for the product. However, the above solution still has the following disadvantages: although this method improves spraying efficiency to a certain extent, because the middle portion of the anti-slip hanging bar is fixed to the main bar, the position of the anti-slip hanging bar cannot be adjusted. This spraying method may not be sufficient to evenly spray the elastic bars of different shapes on the anti-slip hanging bar. Utility Model Content

[0005] The purpose of the utility model is to provide an electrostatic spraying hanger with high uniformity on the surface of elastic bars, which can solve the problem that the existing spraying method may not be enough to evenly spray elastic bars of different shapes on the anti-slip hanging rod.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: an electrostatic spray hanger with high uniformity of elastic bar surface, comprising a long rod, a plurality of limit grooves are provided on the outer surface of the long rod, a plurality of fixed plates are detachably provided on the outer wall of the long rod, a slide groove is provided on the top surface of the plurality of fixed plates, the vertical section of the slide groove is a cross, a slider is provided for sliding inside the slide groove, the top surface of the slider passes through the slide groove and extends to the top of the fixed plate, the end of the slider close to the long rod is plugged into the inside of the limit groove, the end of the fixed plate away from the long rod is fixedly connected to a cross beam, and the bottom surface of the cross beam is fixedly connected to a plurality of elastic bar hooks.

[0007] Preferably, a threaded hole is opened on one side of several of the fixing plates, a bolt is rotatably provided inside the threaded hole, and one side of the bolt is in contact with one side of the sliding block.

[0008] Preferably, the angle between the plurality of spring bar hooks and the crossbeam is one hundred and twenty degrees.

[0009] Preferably, a first axial hole is formed through the top and bottom ends of the long rod, a long shaft is rotatably arranged inside the first axial hole, the top and bottom ends of the long shaft extend to the outside of the first axial hole, and one end of the long shaft is fixedly connected to a fixed hook.

[0010] Preferably, the bottom end of the long shaft is fixedly connected to a circular disc, and the bottom end of the long rod is in contact with the top surface of the circular disc.

[0011] Preferably, a second axial hole is provided on each of the fixing plates, and the fixing plates 3 can be detachably fixed on the long rod 1 .

[0012] Compared with the existing technology, the electrostatic spray hanger with high uniformity of the elastic strip surface using the above technical solution has the following beneficial effects:

[0013] 1. During use, first adjust the positions of several fixing plates on the long rod. After adjusting the positions, push the slider on the fixing plate so that one end of the slider is inserted into the limit slot on the long rod. Turn the bolts on several fixing plates so that one side of the bolt contacts the other side of the slider, so that several fixing plates are fixed on the long rod. Then put the elastic bars on the elastic bar hooks. Since the fixing plates can be detachably fixed on the long rod, the device can place as many elastic bars as possible, thereby increasing the output of elastic bars for each spraying. Since the distance between the crossbeams is adjustable, it can adapt to elastic bars of different types and sizes. For elastic bars with complex shapes, by changing the angle and position of the fixing plate on the long rod, the coating coverage is ensured to be uniform without dead angles, thereby improving the flatness and aesthetics of the coating and reducing the cost of spraying.

[0014] 2. During use, during the electrostatic spraying process, the spring clip hook maintains a 120-degree angle with the crossbeam. This design ensures that the workpiece rotates smoothly during the spraying process, effectively avoiding poor rotation or jamming caused by an angle that is too small, thereby improving overall work efficiency and spraying quality. When the spring clip hook is at a 120-degree angle with the crossbeam, the spring clip encounters less resistance during rotation, which helps reduce the occurrence of mechanical failures and extends the service life of the equipment. At the same time, because the device can rotate smoothly, the thickness of the sprayed coating can be more uniform, avoiding the problem of local over-thickness or over-thinness, further improving the spraying effect. The 120-degree angle design also helps to reduce dead angles during the spraying process, and the spray gun can more easily cover all areas of the spring clip, reducing missed spraying or uneven spraying. This not only improves the spraying quality, but also reduces the cost of rework and repairs;

[0015] 3. During use, the fixing plate is sleeved on the long rod through the second axis hole, and the connection between the fixing hook and the long rod is reduced. The use of the fixing hook reduces the chance of direct manual contact with the paint and equipment, reduces the risk of safety accidents caused by improper operation, thereby reducing labor intensity and improving production efficiency.

[0025] like Figures 1-4 As shown, the angle between the plurality of spring hooks 7 and the crossbeam 6 is one hundred and twenty degrees.

[0026] During use, during the electrostatic spraying process, the spring clip hook 7 maintains a 120-degree angle with the crossbeam 6. This design ensures smooth rotation of the workpiece during the spraying process, effectively avoiding poor rotation or jamming caused by an angle that is too small, thereby improving overall work efficiency and spraying quality. When the spring clip hook 7 and the crossbeam 6 are at a 120-degree angle, the spring clip encounters less resistance during rotation, which helps reduce mechanical failures and extends the service life of the equipment. At the same time, because the workpiece can rotate smoothly, the thickness of the sprayed coating can be more uniform, avoiding the problem of local over-thickness or over-thinness, further improving the spraying effect. The 120-degree angle design also helps reduce dead angles during the spraying process, allowing the spray gun to more easily cover all areas of the workpiece, reducing missed spraying or uneven spraying. This not only improves the spraying quality, but also reduces the cost of rework and repairs.

[0028] During use, the fixing plate 3 is sleeved on the long rod 1 through the second axial hole 13, and the fixing hook 14 is connected to the long rod 1. The use of the fixing hook 14 reduces the chance of direct manual contact with the paint and equipment, reduces the risk of safety accidents caused by improper operation, thereby reducing labor intensity and improving production efficiency.
