Description

Technical Field

[0001] The present invention relates to the technical field of pipeline galvanizing, and specifically to a device and process for secondary galvanizing of pipelines. Background Art

[0002] Pipeline galvanizing is a process method for treating the surface of pipelines, mainly aiming to improve the corrosion resistance, wear resistance, aesthetics, etc. of pipelines. The common methods include hot-dip galvanizing and electro-galvanizing.

[0003] The patent application with the application number CN201520417685.X discloses a device for secondary galvanizing of arc-shaped pipelines, including a galvanizing tank and a double-rail bracket. The bracket is horizontally arranged above the galvanizing tank. The galvanizing device further includes guide rails, a connecting device, and chucks. The guide rails are horizontally fixed on the bracket. The upper end of the connecting device is slidably connected to the guide rails through pulleys. The lower end of the connecting device is fixedly connected to the chucks. The number of the guide rails, the mounting plates, and the chucks is two, and they are symmetrically arranged along the middle of the guide rails. The two chucks are respectively arranged inside the two ends of the arc-shaped pipeline and are clamped with the inner wall of the arc-shaped pipeline. By arranging the clamping claws inside the arc-shaped pipeline and clamping them with its inner wall, it is avoided that the fixing device of the galvanizing device contacts the outer wall of the arc-shaped pipeline, making the galvanizing of the outer wall of the arc-shaped pipeline more thorough.

[0004] When the existing equipment is in use, there is a problem of low automation level. During the pipeline galvanizing operation, each process operates independently, lacking an effective coordination mechanism, which leads to difficulty in improving production efficiency and inability to meet the production requirements of secondary galvanizing of pipelines. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device and process for secondary galvanizing of pipelines to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A device for secondary galvanizing of pipelines, including a bottom plate. A pushing device is fixedly connected to the top of the bottom plate. A storage tank is fixedly connected to the top of the bottom plate. A driving device is fixedly connected to the top of the bottom plate. The front side of the storage tank is fixedly connected to the pushing device.

This optimization improves the processing efficiency and speeds up the overall production progress. In addition, the automated design of the transport mechanism reduces the manual operation links and the demand for the number of staff. While improving production efficiency, it also reduces the labor intensity of the staff and further enhances the safety and stability of the production process.

[0007] According to the above technical solution, the activity component includes a first sliding block, the outer wall of the second moving device is movably connected to the first sliding block, a first U-shaped frame is fixedly connected to the bottom of the first sliding block, a motor is fixedly connected to the inner wall of the first U-shaped frame, the output end of the motor is fixedly connected to a second U-shaped frame, second connecting plates are fixedly connected to both ends of the second U-shaped frame, and a first limiting column is fixedly connected to the outer wall of the second connecting plate. The rotation of the motor is used to control the deflection direction of the main body of the activity component. By setting the activity component, when performing secondary galvanizing on the pipe, when the pipe needs to be immersed in the zinc solution in the storage tank for galvanizing, it slowly enters the zinc solution at a certain inclination angle. This design effectively avoids the possible impact when the pipe enters the zinc solution, ensures that the zinc solution can evenly adhere to the surface of the pipe, greatly improves the galvanizing quality, and the way the pipe enters the zinc solution obliquely can also reduce the probability of bubbles adhering to the surface of the pipe and reduce the possibility of defects in the galvanized layer.

[0008] According to the above technical solution, a second connecting column is rotatably connected to the inner wall of the second connecting plate through a bearing, a fourth connecting plate is fixedly connected to the outer wall of the second connecting column, a first connecting rod is fixedly connected to the bottom of the fourth connecting plate, a track plate is fixedly connected to the outer wall of the first connecting rod, a third connecting column is fixedly connected to the outer wall of the first connecting rod, a clamping component is movably connected to one end of the first connecting rod away from the third connecting column, a sliding frame is movably connected to the outer wall of the third connecting column, a first push rod is fixedly connected to the top of the sliding frame, a third connecting plate is fixedly connected to the outer wall of the first push rod, and the outer wall of the third connecting plate is fixedly connected to the second connecting plate.

[0009] According to the above technical solution, a rotating plate is rotatably connected to the outer wall of the second connecting plate through a bearing. One end of the rotating plate away from the second connecting plate is fixedly connected to a first baffle. A limiting groove is formed in the bottom of the rotating plate. A first connecting column is fixedly connected to the outer wall of the rotating plate. A moving frame is movably connected to the inner wall of the first moving device. By driving the movement of the moving frame by the first moving device, the function of controlling the deflection angle of the first baffle is achieved.

[0010] According to the above technical solution, the clamping assembly includes an upper clamping plate. Right-angle plates are fixedly connected to both ends of the upper clamping plate. A second sliding block is fixedly connected to one end of the right-angle plate away from the upper clamping plate. The outer wall of the second sliding block is movably connected to a first connecting rod. An elastic assembly is fixedly connected to the outer wall of the first connecting rod. One end of the elastic assembly away from the first connecting rod is fixedly connected to the second sliding block. A stress roller is rotatably connected to the side of the second sliding block away from the first connecting rod through a bearing. A lifting seat is fixedly connected to the top of the second moving device. A third moving device is fixedly connected to the outer wall of the lifting seat. A pushing frame is movably connected to the inner wall of the third moving device. By driving the movement of the pushing frame by the third moving device, the function of controlling the position of the clamping assembly is achieved. By setting the clamping assembly, as the clamping assembly moves, the pipe will gradually approach and immerse into the zinc liquid in the material storage tank. When the clamping assembly moves to a specific distance, the fixing of the pipe will be automatically released, allowing the pipe to fall into the zinc liquid under its own weight. While ensuring the angle of the pipe entering the zinc liquid, the problem that the outside of the pipe cannot be completely in contact with the zinc liquid due to the contact between the clamping head and the pipe is avoided, ensuring the galvanizing effect.

[0011] According to the above technical solution, a sliding column is movably connected to the inner wall of the upper clamping plate. A lower clamping plate is fixedly connected to the bottom of the sliding column. A stress plate is fixedly connected to the top of the sliding column.

An extension plate is fixedly connected to the outer wall of the fourth connecting plate. A pressure column is fixedly connected to the outer wall of the extension plate. By applying pressure to the stress plate by the pressure column, the function of controlling the height of the lower clamping plate is achieved.

[0012] According to the above technical solution, the adjusting mechanism includes a connecting plate five, the bottom of the bracket is fixedly connected to the connecting plate five, the inner side of the connecting plate five is rotatably connected to a push rod two through a bearing, the bottom of the connecting plate five is fixedly connected to a push rod three, the bottom of the push rod three is fixedly connected to a connecting rod two, the bottom of the push rod two is rotatably connected to the connecting rod two through a bearing, the outer wall of the connecting rod two is fixedly connected to the connecting rod three, the outer wall of the connecting rod three is fixedly connected to a limiting column two, the outer wall of the limiting column two is movably connected to a pushing plate one, and the top of the pushing plate one is fixedly connected to a pushing plate Plate two, through the linkage of push rods two and three, drives connecting rod two to deflect, plays the role of controlling the deflection angle and height of limiting column two. By setting an adjustment mechanism, when the pipeline is completely immersed in the zinc liquid, it can prevent the pipeline from sinking directly to the bottom, avoid contact between the bottom of the storage tank and the pipeline, and prevent such contact from affecting the secondary galvanizing effect of the pipeline. At the same time, limiting column two used to limit the position of the pipeline is located on the inner wall of the pipeline. This layout allows the equipment to control the position of the pipeline while ensuring that the secondary galvanizing process of the outer wall of the pipeline is not disturbed, thereby ensuring the uniformity and integrity of the galvanized layer.

[0013] The secondary galvanizing process for pipes includes the following steps: S1. When the pipe needs to be galvanized for the second time, the pipe to be fed is aligned by the mobile frame, and then the mobile device is started to lift the mobile frame. The lifted mobile frame will move the baffle plate away from the front of the track plate, and then the feeding device will push the pipe into the track plate and fix it by the clamping assembly; S2. After the fixation is completed, the moving device 2 is started to drive the movable component to move. When the movable component moves, the motor is also started and drives the track plate to deflect. After the movable component moves to the top of the storage tank, the push rod 1 is started to drive the track plate to deflect downward. When the track plate deflects downward, the baffle plate will also be offset from the front end of the track plate; S3. After the track plate has completed its deflection, the moving device 3 is started to drive the push frame to move. The moving push plate will push the clamping assembly to move. At this time, the pipes that need to be galvanized twice will also be pushed into the storage tank, and the pipes will be sleeved on the outside of the limiting column 2. As the clamping assembly moves, when the clamping assembly is subjected to the external force of the pressure column, it will automatically release the fixation of the pipe and allow the pipe to be completely sleeved on the limiting column 2 under the drive of its own weight. S4. After the pipe is put on the limiting column 2, first start the push rod 2 to make the limiting column 2 deflect downward. At this time, the pipe will be completely immersed in the zinc liquid. After the pipe is galvanized, the push rods 2 and 3 will pull up the limiting column 2 horizontally. After the pulling up operation is completed, the pushing device drives the push plates 1 and 2 to move, and pushes the pipe on the limiting column 2 into the driving device, and transports it to the subsequent processing device. The position of the limiting column will also be reset by the push rods 2 and 3.

[0014] Pipe secondary galvanizing device and process, including the following steps: Compared with the prior art, the present invention provides a pipe secondary galvanizing device and process, having the following beneficial effects: 1. By setting up a transportation mechanism, when the device is performing pipe galvanizing operations, it can shorten the time required for feeding and discharging. This optimization improves the processing efficiency, speeds up the overall production progress. In addition, the automated design of the transportation mechanism reduces the manual operation links, reduces the demand for the number of staff, improves the production efficiency, and at the same time reduces the labor intensity of the staff, further enhancing the safety and stability of the production process.

[0015] 2. By setting up a movable component, when performing secondary galvanizing on the pipe, when the pipe needs to be immersed in the zinc solution in the storage tank for galvanizing, it slowly enters the zinc solution at a certain inclination angle. This design effectively avoids the impact that may occur when the pipe enters the zinc solution, ensures that the zinc solution can evenly adhere to the pipe surface, greatly improves the galvanizing quality, and the way of the pipe being inclined and immersed in the zinc solution can also reduce the probability of bubbles adhering to the pipe surface, reducing the possibility of defects in the galvanized layer.

[0016] 3. By setting up a clamping component, as the clamping component moves, the pipe will gradually approach and immerse into the zinc solution in the storage tank. When the clamping component moves to a specific distance, it will automatically release the fixation of the pipe, allowing the pipe to fall into the zinc solution under its own weight. While ensuring the angle of the pipe entering the zinc solution, it avoids the problem that the outer part of the pipe cannot be in full contact with the zinc solution due to the contact between the clamping head and the pipe, ensuring the galvanizing effect.

[0017] 4. By setting up an adjustment mechanism, when the pipe is completely immersed in the zinc solution, it can prevent the pipe from directly sinking to the bottom, avoid the contact between the bottom of the storage tank and the pipe, prevent the impact on the secondary galvanizing effect of the pipe due to this contact. At the same time, the limiting column two for restricting the position of the pipe is located inside the pipe wall. This layout method enables the device to control the position of the pipe while ensuring that the secondary galvanizing process on the outer wall of the pipe is not interfered, thus ensuring the uniformity and integrity of the galvanized layer.

[0027] Embodiment 2: Please refer to Figures 4 - 9, on the basis of the first embodiment, the present invention provides a technical solution: The movable component 21 includes a first sliding block 211. The outer wall of the second moving device 202 is movably connected to the first sliding block 211. A first U-shaped frame 212 is fixedly connected to the bottom of the first sliding block 211. A motor 213 is fixedly connected to the inner wall of the first U-shaped frame 212. The output end of the motor 213 is fixedly connected to a second U-shaped frame 214. Both ends of the second U-shaped frame 214 are fixedly connected to second connecting plates 215. A first limiting column 217 is fixedly connected to the outer wall of the second connecting plate 215. The rotation of the motor 213 controls the deflection direction of the main body of the movable component 21. A second connecting column 2113 is rotatably connected to the inner wall of the second connecting plate 215 through a bearing. A fourth connecting plate 2112 is fixedly connected to the outer wall of the second connecting column 2113. A first connecting rod 2116 is fixedly connected to the bottom of the fourth connecting plate 2112. A track plate 2117 is fixedly connected to the outer wall of the first connecting rod 2116. A third connecting column 2118 is fixedly connected to the outer wall of the first connecting rod 2116.

A third connecting plate 216 is fixedly connected to the outer wall of the first push rod 2119. The outer wall of the third connecting plate 216 is fixedly connected to the second connecting plate 215. The movement of the first push rod 2119 drives the third connecting column 2118 to move, controlling the deflection angle of the track plate 2117. A rotating plate 218 is rotatably connected to the outer wall of the second connecting plate 215 through a bearing. A first baffle 2111 is fixedly connected to the end of the rotating plate 218 far from the second connecting plate 215. A limiting groove 219 is formed in the bottom of the rotating plate 218. A first connecting column 2110 is fixedly connected to the outer wall of the rotating plate 218. A moving frame 107 is movably connected to the inner wall of the first moving device 106. When the movable component 21 is above the storage tank 102, the first push rod 2119 is started to drive the sliding frame 2120 to move. The moving sliding frame 2120 drives the first connecting rod 2116 to deflect through the third connecting column 2118. The deflected first connecting rod 2116 aligns the deflection angle of the track plate 2117 with the deflection angle of the second limiting column 306. Then, the movement of the clamping component 22 drives the pipeline onto the second limiting column 306.

[0028] The clamping assembly 22 includes an upper clamping plate 221. Right-angle plates 222 are fixedly connected to both ends of the upper clamping plate 221. A second sliding block 223 is fixedly connected to the end of the right-angle plate 222 away from the upper clamping plate 221. The outer wall of the second sliding block 223 is movably connected to the first connecting rod 2116. An elastic component 2121 is fixedly connected to the outer wall of the first connecting rod 2116. One end of the elastic component 2121 away from the first connecting rod 2116 is fixedly connected to the second sliding block 223. A force-bearing roller 224 is rotatably connected to the side of the second sliding block 223 away from the first connecting rod 2116 through a bearing. A lifting seat 204 is fixedly connected to the top of the second moving device 202. A third moving device 205 is fixedly connected to the outer wall of the lifting seat 204. A pushing frame 206 is movably connected to the inner wall of the third moving device 205. By driving the pushing frame 206 to move through the third moving device 205, the position of the clamping assembly 22 can be controlled. A sliding column 225 is movably connected to the inner wall of the upper clamping plate 221. A lower clamping plate 226 is fixedly connected to the bottom of the sliding column 225. A force-bearing plate 227 is fixedly connected to the top of the sliding column 225. A spring 228 is sleeved on the outer wall of the sliding column 225.

An extension plate 2114 is fixedly connected to the outer wall of the fourth connecting plate 2112. A pressure column 2115 is fixedly connected to the outer wall of the extension plate 2114. When a pipeline needs to enter the storage tank 102, start the third moving device 205 to drive the pushing frame 206 to move. The moving pushing frame 206 will drive the upper clamping plate 221 and the lower clamping plate 226 to move through the force-bearing roller 224. The moving upper clamping plate 221 and lower clamping plate 226 will push the unprocessed pipeline out of the track plate 2117. As the upper clamping plate 221 and the lower clamping plate 226 move, the force-bearing plate 227 at the top will be squeezed by the pressure column 2115. Driven by the extrusion of the pressure column 2115, the force-bearing plate 227 moves downward. The downward-moving force-bearing plate 227 drives the lower clamping plate 226 to move downward, thereby releasing the fixation of the pipeline and allowing the pipeline to fall onto the second limiting column 306.

[0029] The secondary galvanizing process of the pipeline includes the following steps: S1. When secondary galvanizing of the pipeline is required, align the pipeline to be fed through the moving frame 107, and then start the first moving device 106 to lift the moving frame 107. The lifted moving frame 107 will move the first baffle 2111 away from the front of the track plate 2117. Then, the feeding device 105 will push the pipeline into the track plate 2117 and fix it by the clamping assembly 22; S2, after the fixation is completed, the moving device 202 is started to drive the movable component 21 to move. When the movable component 21 moves, the motor 213 is also started and drives the track plate 2117 to deflect 90 degrees. After the movable component 21 moves to the top of the material storage tank 102, the push rod 1 2119 is started to drive the track plate 2117 to deflect downward. When the track plate 2117 deflects downward, the baffle plate will also be offset from the front end of the track plate 2117; S3. After the track plate 2117 has completed its deflection, the moving device 3 205 is started to drive the push frame 206 to move. The moving push plate will push the clamping assembly 22 to move. At this time, the pipe that needs to be galvanized twice will also be pushed into the storage tank 102, and the pipe will be sleeved on the outside of the limiting column 2 306. As the clamping assembly 22 moves, when the clamping assembly 22 is subjected to the external force of the pressure column 2115, it will automatically release the fixation of the pipe and allow the pipe to be completely sleeved on the limiting column 2 306 under the drive of its own weight. S4. After the pipe is sleeved on the limiting column 2 306, first start the push rod 2 302 to make the limiting column 2 306 deflect downward. At this time, the pipe will be completely immersed in the zinc liquid. After the pipe is galvanized, the push rod 2 302 and the push rod 3 303 will pull up the limiting column 2 306 horizontally. After the pulling up operation is completed, the pushing device 101 drives the pushing plate 1 307 and the pushing plate 2 308 to move, and push the pipe on the limiting column 2 306 into the driving device 103, and transport it to the subsequent processing device. The position of the limiting column will also be reset under the drive of the push rod 2 302 and the push rod 3 303.
