Description

Technical Field

[0001] This utility model relates to the technical field of spraying coating on the housing of power distribution cabinets, and in particular to a coating device for the housing of power distribution cabinets. Background Technology

[0002] Distribution cabinets are a crucial component of power systems, responsible for distributing electrical energy at the end of the system and monitoring and controlling power lines and equipment. To extend the service life of the distribution cabinet housing, a protective coating is applied to its surface during manufacturing. In the prior art, utility model patent application number 202323494520.6 discloses a spraying device with multi-directional spraying capabilities, mainly composed of a base and a spraying box. In use, the workpiece to be sprayed is fed into the spraying box, and then sprayed. However, this device suffers from the following problem: sometimes rust on the workpiece surface affects the adhesion of the coating, making it inconvenient to use. Therefore, a spraying mechanism with rust removal capabilities is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a coating device for a distribution cabinet housing that can remove rust from the surface of the distribution cabinet housing before applying paint, thereby improving the adhesion of the paint to the surface of the distribution cabinet housing. This device is convenient to use, reliable, and highly practical.

[0004] This utility model discloses a coating device for a distribution cabinet housing, comprising a base plate and a disc; it also includes a rotating mechanism, a pressing mechanism, a moving mechanism, a spraying mechanism, and a rust removal mechanism. The disc is mounted on the base plate via the rotating mechanism, which rotates the disc. The pressing mechanism is located above the disc and has a pressing and fixing function. The spraying and rust removal mechanisms are both mounted on the moving mechanism, which moves the spraying and rust removal mechanisms. When it is necessary to spray paint the surface of the distribution cabinet housing, the distribution cabinet housing is first placed on the upper end of the disc, with one end face of the distribution cabinet housing facing the rust removal mechanism. Then, the pressing mechanism presses the distribution cabinet housing... The housing is pressed and fixed onto the disc. Then, the rust removal mechanism removes rust from the surface of the distribution cabinet housing. At the same time, the rotating mechanism can be opened to make the disc drive the distribution cabinet housing to rotate, so that each end face of the distribution cabinet housing rotates in sequence to the side facing the spraying mechanism for rust removal. After the rust removal of the distribution cabinet housing is completed, the moving mechanism moves the spraying mechanism to the side facing the distribution cabinet housing, and then the spraying mechanism sprays paint onto the surface of the distribution cabinet housing. It can remove rust from the surface of the distribution cabinet housing before applying paint, which improves the adhesion of paint to the surface of the distribution cabinet housing. It is convenient to use and has high reliability and practicality.

[0005] Preferably, the rotating mechanism includes a support shaft, bevel gear A, bevel gear B, a drive shaft, a fixed plate, and a stepper motor. The support shaft is rotatably mounted on the base plate, and the disc is fixedly mounted on the upper end of the support shaft. Bevel gear A is fixedly fitted onto the support shaft, and bevel gear A meshes with bevel gear B. Bevel gear B is fixedly mounted on the drive shaft, and the drive shaft is rotatably mounted on the fixed plate. The input end of the drive shaft is connected to the stepper motor. Both the fixed plate and the stepper motor are fixedly mounted on the base plate. When the distribution cabinet housing is coated or rusted on the upper end of the disc, the stepper motor can be turned on. The stepper motor drives bevel gear B to rotate bevel gear A through the drive shaft, which in turn drives the support shaft to rotate the disc, thereby rotating the distribution cabinet housing. This allows each end face of the distribution cabinet housing to rotate sequentially to face the spraying mechanism and the rust removal mechanism for spraying or rust removal, facilitating the coating of the distribution cabinet housing surface.

[0006] Preferably, the clamping mechanism includes a hoisting frame, a hydraulic cylinder, a sliding rod, a bearing, a rotating shaft, and a pressure plate. The hydraulic cylinder is fixedly installed on the upper end of the hoisting frame, the sliding rod is slidably installed on the hoisting frame, the upper end of the sliding rod is connected to the output end of the hydraulic cylinder, the bearing is fixedly installed on the lower end of the sliding rod, the rotating shaft is rotatably installed on the bearing, and the pressure plate is fixedly installed on the lower end of the rotating shaft. The rotating shaft is coaxial with the support shaft. The hoisting frame is fixedly hoisted on the workshop support. Before the distribution cabinet housing is sprayed or derusted on the upper end of the disc, the hydraulic cylinder is first opened. The hydraulic cylinder causes the bearing to drive the rotating shaft and the pressure plate to descend through the sliding rod, thereby causing the lower end of the pressure plate to contact the distribution cabinet housing. The pressure plate presses and fixes the distribution cabinet housing on the disc, improving the stability of the distribution cabinet housing during spraying or derusting.

[0007] Preferably, the spraying mechanism includes a storage tank, a delivery pump, a delivery hose, and a nozzle. The storage tank is mounted on a base plate, and the delivery pump is also mounted on the base plate. The input end of the delivery pump is connected to the storage tank, and the output end of the delivery pump is connected to the nozzle via the delivery hose. The nozzle is mounted on a moving mechanism. When spraying the distribution cabinet housing, the moving mechanism moves the nozzle to a position aligned with the distribution cabinet housing. Then, the delivery pump is turned on, allowing the paint from the storage tank to be sprayed sequentially onto the surface of the distribution cabinet housing via the delivery pump, delivery hose, and nozzle. This facilitates the coating of the distribution cabinet housing.

[0008] Preferably, the rust removal mechanism includes a laser rust removal machine, which is mounted on a base plate. The laser rust removal machine is equipped with a connecting line and a laser head. The laser rust removal machine is connected to the laser head via the connecting line, and the laser head is mounted on a moving mechanism. When it is necessary to remove rust from the surface of the power distribution cabinet housing, the moving mechanism moves the laser head to a suitable position for rust removal. Then, the laser head is turned on, and the laser emitted by the laser head removes rust from the surface of the power distribution cabinet housing. This facilitates rust removal from the surface of the power distribution cabinet housing.

[0009] Preferably, the moving mechanism includes an electric slide rail A, a sliding plate, an electric slide rail B, a moving plate, an electric turntable, a rotating shaft, a fixed frame, a servo motor, a lead screw, and a lifting block. Electric slide rail A is mounted on the upper end of the base plate, and the sliding plate is mounted on electric slide rail A. Electric slide rail A is used to move the sliding plate left and right. Electric slide rail B is mounted on the upper end of the sliding plate, and the moving plate is mounted on electric slide rail B. Electric slide rail B is used to move the moving plate forward and backward. The electric turntable is fixedly mounted on the upper end of the moving plate. The rotating shaft is mounted on the rotating end of the upper part of the electric turntable. The fixed frame is fixedly mounted on the upper end of the rotating shaft. The servo motor is fixedly mounted on the upper end of the fixed frame. The lead screw is rotatably mounted on the fixed frame, and the upper end of the lead screw is connected to the output end of the servo motor. The lifting block is screwed to the lead screw and slides up and down on the fixed frame. The laser head and nozzle are respectively fixedly mounted on the left and right ends of the lifting block. When removing rust or spraying paint on the distribution cabinet housing, the servo motor is turned on. The motor drives the lead screw to rotate, which in turn adjusts the height of the lifting block. Opening electric slide rail A allows electric slide rail B, via a sliding plate, to move the moving plate, electric turntable, rotating shaft, and fixed frame left and right, thus moving the lifting block left and right. Simultaneously, opening electric slide rail B allows the moving plate to move forward and backward, which in turn moves the electric turntable, rotating shaft, and fixed frame forward and backward, further moving the lifting block forward and backward. Because the lifting block can move forward and backward, left and right, and its height can be adjusted, it can drive the laser head and nozzle to move accordingly, facilitating the processing of the distribution cabinet housing surface by the laser head and nozzle. When spraying the distribution cabinet housing, opening the electric turntable causes the rotating shaft to rotate horizontally, which in turn causes the fixed frame to rotate the lifting block, rotating the nozzle on the lifting block to face the side of the distribution cabinet housing; this facilitates the movement of the laser head and nozzle.

[0010] Preferably, a positioning line is provided at the upper end of the disc; with the above setting, when the staff places the power distribution cabinet housing on the upper end of the disc, the lower edge of the power distribution cabinet housing can be aligned with the positioning line to ensure the placement posture of the power distribution cabinet housing on the upper end of the disc, which facilitates the positioning of the power distribution cabinet housing.

[0011] Compared with the prior art, the advantages of this utility model are: the surface of the distribution cabinet can be derusted before coating the surface of the distribution cabinet, which improves the adhesion of the coating on the surface of the distribution cabinet, and is convenient to use, reliable and practical.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figures 1 to 5The coating device for the distribution cabinet housing of this utility model includes a base plate 1, a disc 2, a rotating mechanism, a pressing mechanism, a moving mechanism, a spraying mechanism, and a rust removal mechanism. The disc 2 is mounted on the base plate 1 via the rotating mechanism, which is used to rotate the disc 2. The pressing mechanism is located above the disc 2 and has the function of pressing and fixing. The spraying mechanism and the rust removal mechanism are both mounted on the moving mechanism, which is used to move the spraying mechanism and the rust removal mechanism. When it is necessary to spray paint on the surface of the distribution cabinet housing 26, the distribution cabinet housing 26 is first placed on the upper end of the disc 2, so that one end face of the distribution cabinet housing 26 faces the rust removal mechanism. Then, the pressing mechanism presses the distribution cabinet housing 26. Fixed on the disc 2, the rust removal mechanism removes rust from the surface of the distribution cabinet housing 26. Simultaneously, the rotating mechanism can be opened, causing the disc 2 to rotate the distribution cabinet housing 26, rotating each end face of the housing 26 sequentially to the side facing the spraying mechanism for rust removal. After rust removal, the spraying mechanism is moved to the side facing the housing 26 via a moving mechanism, and then paint is sprayed onto the surface of the housing 26. This mechanism removes rust from the surface of the housing 26 before applying paint, improving paint adhesion. It is convenient to use and highly reliable and practical.

[0021] like Figure 1 and Figure 5 The rotating mechanism includes a support shaft 3, bevel gear A4, bevel gear B5, drive shaft 6, fixed plate 7, and stepper motor 8. The support shaft 3 is rotatably mounted on the base plate 1, and the disc 2 is fixedly mounted on the upper end of the support shaft 3. Bevel gear A4 is fixedly fitted on the support shaft 3 and meshes with bevel gear B5. Bevel gear B5 is fixedly mounted on the drive shaft 6, and the drive shaft 6 is rotatably mounted on the fixed plate 7. The input end of the drive shaft 6 is connected to the stepper motor 8. Both the fixed plate 7 and the stepper motor 8 are fixedly mounted on the base plate 1. When the distribution cabinet housing 26 is coated or rusted on the upper end of the disc 2, the stepper motor 8 can be turned on. The stepper motor 8 drives bevel gear B5 to rotate bevel gear A4 through the drive shaft 6, which in turn drives the support shaft 3 to rotate the disc 2, which in turn drives the distribution cabinet housing 26 to rotate. This allows each end face of the distribution cabinet housing 26 to rotate sequentially to the side facing the coating mechanism and the rust removal mechanism for coating or rust removal. This facilitates the coating of the surface of the distribution cabinet housing 26.

[0022] like Figure 1 and Figure 2The clamping mechanism includes a hoisting frame 9, a hydraulic cylinder 10, a sliding rod 28, a bearing 29, a rotating shaft 30, and a pressure plate 31. The hydraulic cylinder 10 is fixedly installed on the upper end of the hoisting frame 9. The sliding rod 28 is slidably installed on the hoisting frame 9, with its upper end connected to the output end of the hydraulic cylinder 10. The bearing 29 is fixedly installed on the lower end of the sliding rod 28. The rotating shaft 30 is rotatably installed on the bearing 29. The pressure plate 31 is fixedly installed on the lower end of the rotating shaft 30, which is coaxial with the support shaft 3. The hoisting frame 9 is fixedly hoisted on a support frame in the workshop. Before the distribution cabinet housing 26 is sprayed or derusted on the upper end of the disc 2, the hydraulic cylinder 10 is first opened. The hydraulic cylinder 10 causes the bearing 29 to drive the rotating shaft 30 and the pressure plate 31 to descend via the sliding rod 28, thereby causing the lower end of the pressure plate 31 to contact the distribution cabinet housing 26. The pressure plate 31 then presses and fixes the distribution cabinet housing 26 onto the disc 2, improving the stability of the distribution cabinet housing 26 during spraying or derusting.

[0023] like Figure 2 and Figure 4 The spraying mechanism includes a storage tank 11, a delivery pump 12, a delivery hose 13, and a nozzle 14. The storage tank 11 is mounted on a base plate 1, and the delivery pump 12 is also mounted on the base plate 1. The input end of the delivery pump 12 is connected to the storage tank 11, and the output end of the delivery pump 12 is connected to the nozzle 14 via the delivery hose 13. The nozzle 14 is mounted on a moving mechanism. When spraying the distribution cabinet housing 26, the moving mechanism moves the nozzle 14 to a position aligned with the distribution cabinet housing 26. Then, the delivery pump 12 is turned on, so that the paint in the storage tank 11 is sprayed onto the surface of the distribution cabinet housing 26 sequentially through the delivery pump 12, the delivery hose 13, and the nozzle 14. This facilitates the coating of the distribution cabinet housing 26.

[0024] like Figure 3 The rust removal mechanism includes a laser rust removal machine, which is mounted on the base plate 1. The laser rust removal machine is equipped with a connecting line and a laser head 15. The laser rust removal machine is connected to the laser head 15 via the connecting line, and the laser head 15 is mounted on the moving mechanism. When it is necessary to remove rust from the surface of the distribution cabinet housing 26, the moving mechanism moves the laser head 15 to a suitable position for removing rust from the distribution cabinet housing 26. Then, the laser head 15 is turned on, and the laser emitted by the laser head 15 removes rust from the surface of the distribution cabinet housing 26. This facilitates the removal of rust from the surface of the distribution cabinet housing 26.

[0025] like Figure 3The moving mechanism includes an electric slide rail A16, a sliding plate 17, an electric slide rail B18, a moving plate 19, an electric turntable 20, a rotating shaft 21, a fixed frame 22, a servo motor 23, a lead screw 24, and a lifting block 25. The electric slide rail A16 is mounted on the upper end of the base plate 1, and the sliding plate 17 is mounted on the electric slide rail A16. The electric slide rail A16 is used to move the sliding plate 17 left and right. The electric slide rail B18 is mounted on the upper end of the sliding plate 17, and the moving plate 19 is mounted on the electric slide rail B18. The electric slide rail B18 is used to move the moving plate 19 back and forth. The electric turntable 20 is fixedly installed. At the upper end of the moving plate 19, a rotating shaft 21 is mounted on the rotating end of the electric turntable 20. A fixed frame 22 is fixedly mounted on the upper end of the rotating shaft 21. A servo motor 23 is fixedly mounted on the upper end of the fixed frame 22. A lead screw 24 is rotatably mounted on the fixed frame 22, and the upper end of the lead screw 24 is connected to the output end of the servo motor 23. A lifting block 25 is screwed onto the lead screw 24. The lifting block 25 is slidably mounted on the fixed frame 22. The laser head 15 and the nozzle 14 are fixedly mounted on the left and right ends of the lifting block 25, respectively. When removing rust or spraying paint on the power distribution cabinet housing 26, the servo motor 23 is turned on. Servo motor 23 drives lead screw 24 to rotate, and the rotating lead screw 24 can adjust the height of lifting block 25. Opening electric slide rail A16 allows electric slide rail B18 to move moving plate 19, electric turntable 20, rotating shaft 21, and fixed frame 22 in the left and right directions via sliding plate 17, thereby moving lifting block 25 in the left and right directions. Simultaneously, opening electric slide rail B18 allows moving plate 19 to move in the front and back directions, thereby moving electric turntable 20, rotating shaft 21, and fixed frame 22 in the front and back directions, thus moving lifting block 25. 5. Moving in the front and back direction; Since the lifting block 25 can move back and forth, move left and right, and adjust its height, it can drive the laser head 15 and the nozzle 14 to move accordingly, which facilitates the processing of the surface of the distribution cabinet housing 26 by the laser head 15 and the nozzle 14; When spraying the distribution cabinet housing 26, the electric turntable 20 is turned on, and the electric turntable 20 drives the rotating shaft 21 to rotate horizontally, which in turn causes the fixed frame 22 to drive the lifting block 25 to rotate, so that the nozzle 14 on the lifting block 25 can rotate to the side facing the distribution cabinet housing 26; This facilitates the movement of the laser head 15 and the nozzle 14.

[0026] Example 2

[0027] Based on Embodiment 1, a positioning line 27 is also provided on the upper end of the disc 2. With the above setting, when the staff places the power distribution cabinet housing 26 on the upper end of the disc 2, the lower edge of the power distribution cabinet housing 26 can be made to fit with the positioning line 27 to ensure the placement posture of the power distribution cabinet housing 26 on the upper end of the disc 2, which facilitates the positioning of the power distribution cabinet housing 26.

[0028] It should be noted that: in this case, the upper surface of the distribution cabinet housing 26 needs to be equipped with cable trays, busbars and other equipment, and an inspection port needs to be reserved on the upper surface of the distribution cabinet housing 26. Therefore, the upper surface of the distribution cabinet does not need to be painted.
