Description

Technical Field

[0001] This invention belongs to the field of power transmission tower manufacturing and processing technology, and specifically relates to an automatic galvanizing device for power transmission towers. Background Technology

[0002] Currently, galvanizing refers to a surface treatment technology that coats the surface of metals, alloys, or other materials with a layer of zinc for aesthetic and rust-preventing purposes. Hot-dip galvanizing is the primary method used. Zinc is readily soluble in both acids and alkalis, hence it is called an amphoteric metal. Zinc remains almost unchanged in dry air. In humid air, a dense film of basic zinc carbonate forms on the zinc surface. Zinc coatings are anodic coatings, primarily used to prevent corrosion of steel; their protective performance is highly dependent on the coating thickness. Passivation treatment, dyeing, or application of a protective agent can significantly improve the protective and decorative properties of zinc coatings.

[0003] During the manufacturing process of power transmission towers, galvanizing is required for the tower parts to extend their service life.

[0004] However, when galvanizing power transmission towers, it is impossible to collect the waste gas generated during the galvanizing process, resulting in the direct diffusion of waste gas and causing environmental pollution, thus failing to meet environmental protection standards.

[0005] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this invention was created to provide an automatic galvanizing device for iron towers to solve the problem. Summary of the Invention

[0006] This invention proposes an automatic galvanizing device for iron towers, which solves the problems in the prior art.

[0007] The technical solution of this invention is implemented as follows: An automatic galvanizing device for iron towers includes a housing, a protective cover detachably mounted on the housing, a protective plate slidably mounted on the protective cover, and a second driving component disposed between the protective cover and the protective plate. Activating the second driving component moves the protective plate along the protective cover to seal the protective cover and the housing. The device is characterized in that: a first support frame is slidably mounted on the housing, a material frame is movably mounted on the first support frame, and a first driving component is detachably mounted on the housing. The first driving component is connected to the first support frame via a transmission mechanism. Activating the first driving component via a transmission mechanism... The mechanism drives the first support frame to move back and forth along the box. A second support frame is slidably installed on the protective cover. A gas collecting pipe is rotatably installed on the second support frame. An elastic component is provided between the second support frame and the gas collecting pipe. A gas collecting port is provided on the gas collecting pipe. An exhaust gas filter is detachably installed on the protective cover. The exhaust gas filter is connected to the gas collecting pipe through a gas delivery hose. A first lever is fixedly installed on the first support frame. A second lever is fixedly installed on the gas collecting pipe. The first lever and the second lever correspond to each other. The first support frame moves the second lever by moving the first lever, which moves the gas collecting pipe and the material frame synchronously.

[0008] As a preferred technical solution: the protective cover has two symmetrical second sliding grooves, the protective plate is slidably installed in the second sliding grooves, and the second driving component is installed in the second sliding grooves.

[0010] As a preferred technical solution: the transmission mechanism includes two adjusting screws rotatably mounted on the housing, the first support frame is threaded onto the adjusting screws, and a second sprocket is fixedly mounted on each of the two adjusting screws. A first sprocket is rotatably mounted on the housing, and the first sprocket and the second sprocket are connected by a chain drive. The first sprocket is connected to a first driving component. When the first driving component is activated, it drives the second sprocket to rotate through the first sprocket, which in turn drives the first support frame to move cyclically back and forth along the housing through the adjusting screws.

[0011] As a preferred technical solution: two symmetrical first sliding grooves are provided on the housing, a first sliding block is fixedly provided on the first support frame, the first sliding block is slidably installed in the first sliding groove, a first screw hole is provided on the first sliding block, and the adjusting screw is threadedly installed in the first screw hole.

[0012] As a preferred technical solution: the first support frame has two corresponding limiting grooves, and the material frame is fixedly provided with a limiting rod. The limiting rod corresponds to the limiting groove. When the material frame is moved into the box, the limiting rod is installed in the limiting groove to connect the material frame to the first support frame.

[0013] As a preferred technical solution: a sliding rod is fixedly provided on the protective cover, and a third sliding groove is fixedly provided on the second support frame, and the sliding rod is slidably installed in the third sliding groove.

[0014] As a preferred technical solution: a rotating shaft is fixedly installed on the second support frame, and a bushing is rotatably installed on the rotating shaft. The bushing is connected and fixed to the gas collecting pipe through a connecting rod.

[0015] As a preferred technical solution: a fourth support frame is fixedly installed on the connecting rod, and a third support frame is fixedly installed on the second support frame. The third support frame and the fourth support frame are connected by an elastic component. A limit block is provided on the box body, and the limit block corresponds to the second support frame. Operating the first lever drives the gas collecting pipe and the material frame to move synchronously through the second lever. The limit block restricts the movement of the second support frame along the protective cover. The first lever drives the connecting rod to rotate around the rotating shaft and compresses the elastic component, causing the first lever to disengage from the second lever.

[0016] After adopting the above technical solution, the beneficial effects of the present invention are:

[0017] 1. Place the power transmission tower workpiece that needs to be galvanized in the material frame, move the material frame into the box, start the first drive component to drive the material frame to move along the box through the first support frame, realize hot-dip galvanizing of the power transmission tower workpiece, the material frame drives the power transmission tower workpiece to move in the galvanizing liquid, thereby completing the galvanizing, improving the comprehensiveness of galvanizing of the power transmission tower workpiece, thereby improving the galvanizing quality.

The first and second levers work together to move the gas collection pipe synchronously with the material frame, so as to quickly collect the waste gas generated during the galvanizing process. This achieves the function of quickly collecting waste gas, preventing the waste gas from being directly emitted and causing pollution, while reducing energy consumption and improving galvanizing efficiency.

Example

[0032] like Figures 1 to 10 As shown, an automatic galvanizing device for iron towers includes a housing 1, a protective cover 16 detachably mounted on the housing 1, a protective plate 18 slidably mounted on the protective cover 16, and a second driving component 19 disposed between the protective cover 16 and the protective plate 18. Activating the second driving component 19 moves the protective plate 18 along the protective cover 16 to seal the protective cover 16 and the housing 1. The device is characterized by: a first support frame 11 slidably mounted on the housing 1, a material frame 14 movably mounted on the first support frame 11, and a first driving component 6 detachably mounted on the housing 1. The first driving component 6 is connected to the first support frame 11 via a transmission mechanism. Activating the first driving component 6 drives the first support frame 11 via the transmission mechanism. 1. The device moves back and forth along the housing 1. A second support frame 26 is slidably installed on the protective cover 16. A gas collecting pipe 32 is rotatably installed on the second support frame 26. An elastic component 36 is provided between the second support frame 26 and the gas collecting pipe 32. A gas collecting port 34 is provided on the gas collecting pipe 32. An exhaust gas filter 21 is detachably installed on the protective cover 16. The exhaust gas filter 21 is connected to the gas collecting pipe 32 through a gas delivery hose. A first lever 12 is fixedly installed on the first support frame 11. A second lever 37 is fixedly installed on the gas collecting pipe 32. The first lever 12 and the second lever 37 correspond to each other. The first support frame 11 moves the second lever 37 through the first lever 12 to move the gas collecting pipe 32 and the material frame 14 synchronously.

[0033] Specifically: the exhaust gas filter 21 is installed on the protective cover 16 by bolts and nuts. The exhaust gas filter 21 is a known technology. An exhaust fan is installed on the exhaust gas filter 21 and is connected to the exhaust gas filter 21. The connection method between the exhaust fan and the exhaust gas filter 21 is a known technology. The exhaust fan is provided with an air inlet 22. The gas collecting pipe 32 is preferably rectangular. An exhaust port 33 is provided on the gas collecting pipe 32. The exhaust port 33 and the air inlet 22 are fixedly and sealed together by a gas delivery hose.

[0034] When in use: Start the exhaust fan. The exhaust gas generated during the galvanizing process enters the gas collection pipe 32 through the gas collection port 34, and then enters the exhaust gas filter 21 through the gas delivery hose to treat the exhaust gas.

[0035] The protective cover 16 has two symmetrical second sliding grooves 17, the protective plate 18 is slidably installed in the second sliding grooves 17, and the second driving component 19 is installed in the second sliding grooves 17.

[0036] There are multiple second drive components 19, and the multiple second drive components 19 drive synchronously.

[0037] Specifically: the second drive component 19 is a hydraulic cylinder or an electric push rod, and a controller 20 is installed on the protective cover 16 by bolts and nuts. The controller 20 is connected to multiple second drive components 19.

[0038] In use: The controller 20 controls the operation of multiple second drive components 19. The multiple second drive components 19 drive the protective plate 18 to move along the second sliding groove 17. The protective plate 18 seals the protective cover 16 and the box 1 to prevent the leakage of exhaust gas generated during the galvanizing process.

[0039] The transmission mechanism includes two adjusting screws 7 rotatably mounted on the housing 1. A first support frame 11 is threaded onto the adjusting screws 7. A second sprocket 8 is fixedly mounted on each of the two adjusting screws 7. A first sprocket 4 is rotatably mounted on the housing 1. The first sprocket 4 and the second sprocket 8 are connected by a chain 5. The first sprocket 4 is connected to the first drive component 6. When the first drive component 6 is started, it drives the second sprocket 8 to rotate through the first sprocket 4, which in turn drives the first support frame 11 to move cyclically back and forth along the housing 1 through the adjusting screws 7.

[0040] Two symmetrical first sliding grooves 2 are provided on the housing 1. A first sliding block 9 is fixedly provided on the first support frame 11. The first sliding block 9 is slidably installed in the first sliding groove 2. A first screw hole 10 is provided on the first sliding block 9. The adjusting screw 7 is threadedly installed in the first screw hole 10.

[0041] Specifically: The housing 1 has a first through hole 3, the adjusting screw 7 is rotatably installed in the first through hole 3, the first driving component 6 is a forward and reverse servo motor, the output end of the forward and reverse servo motor is connected to the first sprocket 4 for transmission, the first sliding groove 2 is preferably concave, and the first sliding block 9 is preferably convex.

[0042] In use: When the forward and reverse servo motor is started, it drives the two second sprockets 8 to rotate synchronously through the transmission of the first sprocket 4 and the chain 5. The second sprockets 8 drive the adjusting screw 7 to rotate. The adjusting screw 7 drives the first sliding block 9 to slide along the first sliding groove 2, thereby driving the first support frame 11 to move along the housing 1. By adjusting the forward or reverse rotation of the forward and reverse servo motor, the first support frame 11 can be driven to move cyclically.

[0043] The first support frame 11 has two corresponding limiting grooves 13. The material frame 14 is fixedly provided with a limiting rod 15, which corresponds to the limiting groove 13. When the material frame 14 is moved into the box 1, the limiting rod 15 is installed in the limiting groove 13 to connect the material frame 14 to the first support frame 11. The limiting rod 15 and the limiting groove 13 are connected by an interference fit.

[0044] A sliding rod 23 is fixedly installed on the protective cover 16, and a third sliding groove 25 is fixedly installed on the second support frame 26. The sliding rod 23 is slidably installed in the third sliding groove 25. The cross-section of the sliding rod 23 is U-shaped, and the cross-section of the third sliding groove 25 corresponds to the sliding rod 23.

[0045] A rotating shaft 27 is fixedly installed on the second support frame 26, and a bushing 30 is rotatably installed on the rotating shaft 27. The bushing 30 is connected and fixed to the air collection pipe 32 through a connecting rod 31.

[0046] A fourth support frame 35 is fixedly installed on the connecting rod 31, and a third support frame 29 is fixedly installed on the second support frame 26. The third support frame 29 and the fourth support frame 35 are connected by an elastic component 36. A limit block 24 is provided on the housing 1. The limit block 24 corresponds to the second support frame 26. The operation of the first lever 12 drives the gas collecting pipe 32 and the material frame 14 to move synchronously through the second lever 37. The limit block 24 limits the movement of the second support frame 26 along the protective cover 16. The first lever 12 drives the connecting rod 31 to rotate around the rotating shaft 27 and compresses the elastic component 36, so that the first lever 12 disengages from the second lever 37.

[0047] Specifically: A limiting plate 28 is detachably installed on the rotating shaft 27 by screws. The diameter of the limiting plate 28 is larger than the diameter of the rotating shaft 27. The limiting plate 28 prevents the bushing 30 from disengaging from the rotating shaft 27. The elastic component 36 is a return spring. One end of the return spring is movably installed on the third support frame 29, and the other end of the return spring is movably installed on the fourth support frame 35.

[0048] In use: The first drive component 6 drives the material frame 14 to move to the right along the box 1. The first lever 12 and the second lever 37 work together to drive the gas collecting pipe 32 to move synchronously with the material frame 14, so as to quickly collect the waste gas generated during the galvanizing process. When the material frame 14 and the gas collecting pipe 32 are moved to the right end of the protective cover 16, the movement of the gas collecting pipe 32 is restricted by the protective cover 16. The material frame 14 continues to move. The first lever 12 drives the second lever 37 to rotate, so that the first lever 12 disengages from the second lever 37. At the same time, the second drive component 19 is activated to drive the protective plate 18 to move upward, so that the galvanized material frame 14 is moved to the outside of the protective cover 16 and the material frame 14 is taken out. The first drive component 6 is activated to drive the first support frame 11 and the gas collecting pipe 32 to reset.

[0049] The automatic galvanizing process for galvanized components of power transmission towers follows these steps:

[0050] A1. Fill the material frame 14 with the power transmission tower parts that need to be galvanized;

[0051] A2. Move the material frame 14 with parts into the first support frame 11, and install it in the limiting groove 13 with the cooperation of the limiting rod 15, so that the material frame 14 is connected and fixed to the first support frame 11, and the material frame 14 is located on the left side of the box 1.

[0052] A3. Start the first drive component 6 to move the first support frame 11 to the right. When the first support frame 11 with the material frame 14 enters the protective cover 16, start the second drive component 19 to drive the protective plate 18 to seal the protective cover 16 with the box 1.

[0053] A4. The first driving component 6 drives the material frame 14 to move to the right along the box 1. The first lever 12 and the second lever 37 work together to drive the gas collection pipe 32 to move synchronously with the material frame 14, so as to quickly collect the waste gas generated during the galvanizing process.

[0054] A5. When the material frame 14 and the gas collecting pipe 32 are moved to the right end of the protective cover 16 through step A4, the movement of the gas collecting pipe 32 is limited by the protective cover 16. The material frame 14 continues to move, and the first lever 12 drives the second lever 37 to rotate, thereby causing the first lever 12 to disengage from the second lever 37. At the same time, the second drive component 19 is activated to drive the protective plate 18 to move upward.

[0055] A6. Move the galvanized material frame 14 to the outside of the protective cover 16 and remove the material frame 14.

[0056] A7. After completing A6, the first drive component 6 is activated to drive the first support frame 11 and the gas collection pipe 32 to reset, thereby realizing the function of quickly collecting exhaust gas and preventing the direct emission of exhaust gas, which would cause pollution.

[0057] The working principle of this invention is as follows: when the exhaust fan is started, the exhaust gas generated during the galvanizing process enters the gas collection pipe 32 through the gas collection port 34, and then enters the exhaust gas filter 21 through the gas delivery hose to treat the exhaust gas.

[0058] The forward and reverse servo motor is started and driven by the first sprocket 4 and chain 5 to drive the two second sprockets 8 to rotate synchronously. The second sprockets 8 drive the adjusting screw 7 to rotate. The adjusting screw 7 drives the first sliding block 9 to slide along the first sliding groove 2, thereby driving the first support frame 11 to move along the housing 1. By adjusting the forward or reverse rotation of the forward and reverse servo motor, the first support frame 11 can be driven to move cyclically.

[0059] The controller 20 controls multiple second drive components 19 to work. The multiple second drive components 19 drive the protective plate 18 to move along the second sliding groove 17. The protective plate 18 seals the protective cover 16 and the box 1 to prevent the exhaust gas generated during the galvanizing process from leaking out.

[0060] The first drive component 6 drives the material frame 14 to move to the right along the box 1. The first lever 12 and the second lever 37 work together to drive the gas collecting pipe 32 to move synchronously with the material frame 14, so as to quickly collect the waste gas generated during the galvanizing process. When the material frame 14 and the gas collecting pipe 32 move to the right end of the protective cover 16, the movement of the gas collecting pipe 32 is restricted by the protective cover 16. The material frame 14 continues to move. The first lever 12 drives the second lever 37 to rotate, so that the first lever 12 disengages from the second lever 37. At the same time, the second drive component 19 is activated to drive the protective plate 18 to move upward, so that the galvanized material frame 14 is moved to the outside of the protective cover 16 and the material frame 14 is taken out. The first drive component 6 is activated to drive the first support frame 11 and the gas collecting pipe 32 to reset.
