Description

Technical Field

[0001] This invention relates to the field of coating processing technology, and in particular to a composite coating equipment for surface protection of power fittings. Background Technology

[0002] Power fittings are metal accessories that connect and combine various devices in a power system, serving to transmit mechanical and electrical loads and provide certain protective functions. They are crucial for the effective and safe operation of power transmission. Power fittings are the foundation of power grid operation, affecting the operational status of the entire transmission line. They are not only related to the safe operation of the power grid but also closely connected to the safety of people and property. Traditional fittings are primarily made of malleable cast iron or Q235 steel, while fastening components are made of carbon steel, alloy steel, and a small amount of stainless steel. These materials have poor corrosion resistance and require hot-dip galvanizing before use.

[0003] Vacuum ion plating is a process that uses low pressure to ionize vaporized coating materials and then attach them to the surface of a workpiece. During production, the workpiece needs to be placed in a low-pressure environment. Due to the high cost of coating, the coating area on the workpiece surface needs to be controlled, and only specified areas of the workpiece need to be coated.

[0004] In the existing technology, when coating the splice pipes used for connecting steel-cored aluminum stranded wires, the workpiece clamping device is too simple and not suitable for the high-precision machining in the conceptual design, which affects the coating effect. Moreover, the operation of picking up and putting down the workpiece each time is cumbersome and not conducive to improving the processing speed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as workpiece clamping devices being too rudimentary, unsuitable for high-precision machining in conceptual designs, affecting coating effects, and cumbersome operation during each workpiece handling, which hinders the improvement of processing speed. Therefore, this invention proposes a composite coating device for surface protection of power fittings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A composite coating device for surface protection of power fittings includes a first housing, a second housing rotatably disposed on one side of the first housing, two sets of magnetron sputtering and ion plating for coating the connecting pipe on the first housing, a long filament for etching the connecting pipe on the second housing, a connecting frame for connecting to a vacuum machine fixedly disposed through one side of the first housing, a base fixedly disposed inside the first housing, a placement frame for clamping the connecting pipe on the top of the base, and a motor drive shaft disposed on the first housing, the motor drive shaft passing through the top of the base and engaging with the placement frame to drive the placement frame to rotate.

[0008] A vehicle body is provided on one side of the first housing. The vehicle body is used in conjunction with the placement rack to remove the placement rack from the second housing for replacement of the extension pipe.

[0009] The placement rack includes two fixed plates, and a plurality of second connecting plates and a first connecting plate are provided between the two fixed plates. The corresponding second connecting plates and the first connecting plates can clamp the extension pipe.

[0010] The braking mechanism, installed on the vehicle body, is used to move the second connecting plate away from the first connecting plate to release the clamping of the connecting pipe.

[0011] In one possible design, a first rotating shaft is slidably disposed between the two fixed disks. Multiple first connecting disks are rotatably sleeved on the first rotating shaft, and multiple second connecting disks are slidably sleeved on the first rotating shaft. Multiple springs located on the top of the first connecting disks are sleeved on the outer wall of the first rotating shaft. The two ends of the springs are fixedly connected to the adjacent sides of the second connecting disks and the first connecting disks, respectively. Multiple guide posts are rotatably disposed between the two fixed disks. The first connecting disks are rotatably sleeved on the multiple guide posts, and the second connecting disks are slidably sleeved on the multiple guide posts. The motor drive shaft is engaged with the first rotating shaft to drive the guide posts and the first connecting disks to rotate.

[0012] In one possible design, an internal gear ring is rotatably mounted on the bottom of the fixed disk below, and the internal gear ring is engaged with the base. The top of the base has a second sliding groove corresponding to the guide rail. A gear that meshes with the internal gear ring is fixedly sleeved on the outer wall of the guide post. Multiple second rotating shafts are rotatably mounted on the adjacent sides of the second connecting disk and the first connecting disk. Clamping plates for holding the connecting pipe are fixedly mounted on the adjacent sides of the two sets of second rotating shafts. Synchronous pulleys are fixedly sleeved on the outer walls of the second rotating shafts on the first connecting disk and the guide post. The outer walls of the two synchronous pulleys are driven by the same synchronous belt.

[0013] In one possible design, the bottom of the first rotating shaft extends to the bottom of the internal gear ring, the top of the base has a third U-shaped hole corresponding to the first rotating shaft, the motor drive shaft is located in the third U-shaped hole, the top of the motor drive shaft has a rectangular opening, the bottom of the first rotating shaft is inserted into the rectangular opening, the bottom of the internal gear ring is fixedly provided with two guide rails, and the top of the base has a second sliding groove corresponding to the guide rails.

[0014] In one possible design, the top of the vehicle body has a second U-shaped hole corresponding to the first rotating shaft, and the top of the vehicle body has a first sliding groove corresponding to the guide rail.

[0015] In one possible design, the braking mechanism includes a handle fixedly mounted on the top of the vehicle body. An L-shaped rotating plate is rotatably sleeved on the outer wall of the handle. A first U-shaped hole corresponding to a first rotating shaft is opened on the top of the L-shaped rotating plate. A limiting plate that abuts against the L-shaped rotating plate is fixedly mounted on the top of the first rotating shaft. A plurality of limiting rings located at the bottom of the first connecting disc are fixedly sleeved on the outer wall of the first rotating shaft.

[0016] In one possible design, an arc-shaped block is fixedly provided on one side of the L-shaped rotating plate, and positioning holes are provided on one side of both the arc-shaped block and the L-shaped rotating plate. A fixing plate is fixedly sleeved on the outer wall of the handle, and a pin corresponding to the positioning hole is threaded through one side of the fixing plate.

[0017] In one possible design, the wheels at the bottom of the vehicle body are omnidirectional wheels with brakes.

[0018] In this application, during use, pushing one end of the L-shaped rotating plate closer to the placement rack utilizes the lever principle to tilt the other end of the L-shaped rotating plate upwards, inserting the pin into the positioning hole on the arc-shaped block. This causes the first rotating axis to move upwards via the limiting plate. During this movement, the second connecting plate moves upwards via the limiting ring. Then, the extension pipe is placed on the clamping plate on the first connecting plate. The pin is then removed, and the L-shaped rotating plate is slowly rotated back to its original position. At this time, the second connecting plate can return to its original position downwards under the force of the spring, and the first rotating axis returns to its original position downwards via the limiting ring, clamping the extension pipe between the two clamping plates. Finally, the vehicle body is moved so that the placement rack aligns with the base. Then, the placement rack is moved from the vehicle body to the base, and the bottom end of the first rotating shaft is locked in the rectangular opening. The vehicle body is then removed, and the second housing is covered. Then, magnetron sputtering, ion plating, and long filament etching and coating are performed on the extension pipe in sequence. At the same time, the motor drive shaft is started to drive the first rotating shaft to rotate. The rotation of the first rotating shaft can drive the guide post and the first connecting plate to rotate simultaneously. While rotating, the guide post will be driven to rotate through the internal gear ring and gear. The rotation of the guide post can drive the second rotating shaft to rotate through the synchronous pulley and synchronous belt, thereby driving the extension pipe to rotate through the clamping plate. The extension pipe rotates around the first rotating shaft while also rotating on its own axis.

[0019] After the coating is completed, open the second housing and push the vehicle body to one side of the base. Take the placement rack from the base to the vehicle body, and then push the placement rack on the other vehicle body to one side of the base to continue coating.

[0020] In this invention, the composite coating equipment for surface protection of power fittings allows for workpiece clamping outside the first housing by setting up a placement rack, and the cyclic use of multiple placement racks saves a lot of clamping time while improving coating efficiency.

[0021] In this invention, the composite coating equipment for surface protection of power fittings drives the first rotating shaft to rotate through the third U-shaped hole, which in turn drives the extension pipe to rotate around the first rotating shaft. During the rotation, the extension pipe can also rotate on its own axis, thereby improving the coating effect.

[0022] In this invention, the composite coating equipment for surface protection of power fittings makes clamping the extension pipes convenient by clamping them between two clamping plates, and makes it convenient to use by simultaneously releasing the fixing of all extension pipes by pulling the first rotating shaft upward.

[0023] In this invention, by making the mounting rack detachable from the base and using it in conjunction with the vehicle body, it is possible to clamp the extension pipes on the outside of the first housing. Furthermore, by moving the L-shaped rotating plate, the first rotating shaft can be raised and lowered, allowing all extension pipes to be fixed simultaneously. This makes clamping convenient, and the mounting rack can be reused, thereby improving coating efficiency. Attached Figure Description

[0035] A vehicle body 7 is provided on one side of the first housing 1. The vehicle body 7 is used in conjunction with the placement rack 8 to remove the placement rack 8 from the second housing 2 for replacement of the connecting pipe.

[0036] The placement rack 8 includes two fixed plates 13, and a plurality of second connecting plates 16 and first connecting plates 15 are provided between the two fixed plates 13. The corresponding second connecting plates 16 and first connecting plates 15 can clamp the extension pipe.

[0037] The braking mechanism, installed on the vehicle body 7, is used to move the second connecting plate 16 away from the first connecting plate 15 to release the clamping of the connecting pipe. Through the cooperation of the placement rack 8 and the vehicle body 7, the placement rack 8 can be taken out from the second housing 2 to replace the connecting pipe. Multiple placement racks 8 can be used in a cycle to improve processing efficiency. The connecting pipe can be clamped by the second connecting plate 16 and the first connecting plate 15. After moving to the vehicle body 7, the clamping of the connecting pipe can be released by the braking mechanism, making it easy to use.

The two ends of each spring 25 are fixedly connected to the adjacent sides of the second connecting disks 16 and the first connecting disks 15, respectively. Multiple guide posts 14 are rotatably disposed between the two fixed disks 13. The first connecting disks 15 are rotatably mounted on the multiple guide posts 14, and the second connecting disks 16 are slidably mounted on the multiple guide posts 14. On the guide post 14, the motor drive shaft 35 is engaged with the first rotating shaft 26 to drive the guide post 14 and the first connecting plate 15 to rotate. By starting the motor drive shaft 35, the first rotating shaft 26 can be driven to rotate. The rotation of the first rotating shaft 26 can drive the fixed plate 13 to rotate. During the rotation of the fixed plate 13, the first connecting plate 15 and the second connecting plate 16 can be driven to rotate simultaneously through the guide post 14, thereby driving the extension pipe to rotate around the first rotating shaft 26. Furthermore, the second connecting plate 16 can move downward and approach the first connecting plate 15 under the force of the spring 25, thereby clamping the extension pipe.

[0039] An internal gear ring 29 is rotatably mounted at the bottom of the lower fixed plate 13. The internal gear ring 29 is engaged with the base 6. The top of the base 6 has a second sliding groove 38 corresponding to the guide rail 30.

Synchronous pulleys 33 are fixedly sleeved on the outer walls of the second rotating shafts 32 on the first connecting plate 15 and the guide post 14. The outer walls of the two synchronous pulleys 33 are driven by the same synchronous belt 34. When the fixed plate 13 rotates, it will drive the guide post 14 to rotate. During the rotation, the guide post 14 will be driven to rotate through the gear 31 and the internal gear ring 29. During the rotation of the guide post 14, the clamping plates 24 can be driven to rotate through the synchronous pulleys 33 and the synchronous belt 34, thereby driving the connecting pipe to rotate. It can rotate around the first rotating shaft 26 and rotate on its own axis, improving the processing effect.

[0040] The top of the vehicle body 7 is provided with a second U-shaped hole 23 corresponding to the first rotating shaft 26, and the top of the vehicle body 7 is provided with a first sliding groove 22 corresponding to the guide rail 30. The placement rack 8 can be restricted on the vehicle body 7 by the setting of the second U-shaped hole 23 and the first sliding groove 22, and will not detach during movement.

[0041] The braking mechanism includes a handle 10 fixedly mounted on the top of the vehicle body 7. An L-shaped rotating plate 11 is rotatably sleeved on the outer wall of the handle 10. The top of the L-shaped rotating plate 11 has a first U-shaped hole 21 corresponding to the first rotating shaft 26. A limiting plate 27 that abuts against the L-shaped rotating plate 11 is fixedly mounted on the top of the first rotating shaft 26. Multiple limiting rings 28 located at the bottom of the first connecting plate 15 are fixedly sleeved on the outer wall of the first rotating shaft 26. By turning one end of the L-shaped rotating plate 11, the other end of the L-shaped rotating plate 11 can be tilted upward, thereby using the lever principle to drive the first rotating shaft 26 to move upward. The upward movement of the first rotating shaft 26 can drive the second connecting plate 16 to move upward through the limiting rings 28, thereby releasing the clamping of the connecting pipe, making it easy to operate, and enabling the release of all connecting pipes from fixation.
