Description

Technical Field

[0001] This invention relates to the field of hot-dip galvanizing technology, specifically to equipment for hot-dip galvanizing the surface of angle steel for power transmission towers. Background Technology

[0002] Hot-dip galvanizing is one of the most basic and widely used methods for steel corrosion protection in the world. It is widely used in various sectors of the national economy, including metallurgy, building materials, power, transportation, and agriculture. Hot-dip galvanizing of steel pipes involves immersing clean, processed steel pipes in molten zinc for hot-dip galvanizing, resulting in metal pipes with excellent surface properties.

[0003] In the existing technology, when hot-dip galvanizing angle steel, the angle steel is usually entered into the pickling tank from the side and then taken out from the other side after pickling. However, some pickling solution is brought out during the entry process, and a large amount of pickling solution is still adhered to its surface when it is taken out. When the angle steel is then hot-dip galvanized, the angle steel will overlap, which will greatly reduce the contact area between the angle steel and the hot zinc, resulting in incomplete galvanizing. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a hot-dip galvanizing equipment for the surface of angle steel of power transmission towers, comprising an acid pickling tank, a regulator, a cleaner, and a limiter. The regulator is fixedly installed on the outside of the acid pickling tank, the cleaner is fixedly installed on the outside of the regulator, the cleaner and the regulator are at a 90° angle, and the limiter is fixedly installed on the side of the acid pickling tank away from the cleaner.

[0005] The bottom of the pickling tank is fixedly connected to a support rod, the outside of the support rod is fixedly connected to a galvanizing tank, and a stacking device is fixedly installed inside the galvanizing tank.

[0006] The limiter includes a current tube, the outer side of which is sleeved on the outer side of the pickling tank. The inner end of the current tube is connected to a flow ring, and the inner side of the flow ring is connected to an electromagnet. A magnetic shielding sleeve is fixedly connected to the outer side of the electromagnet, and a vertical plate is fixedly connected to the inner side of the magnetic shielding sleeve. A fixed rail is fixedly connected to the inner side of the vertical plate, and a traction sleeve is slidably installed inside the fixed rail. A sliding rod is fixedly connected to the inner side of the traction sleeve, and a pressure plug is fixedly connected to the bottom of the sliding rod. The outer side of the pressure plug compresses a movable bladder. The air in the space created by the bottom of the pressure plug and the movable bladder is compressed, causing the lower half of the movable bladder to remain bulging, thus sealing the five movable bladders. This prevents acidic liquid from flowing out when the angle steel is inserted into the pickling tank through the movable bladders. In addition, the compression and friction of the movable bladders on the angle steel can pre-clean the surface of the angle steel.

[0007] The regulator includes a slide rail, which is fixedly installed on the outside of the pickling tank. A slider is slidably installed on the outside of the slide rail, and a fixing sleeve is fitted on the surface of the slider. A hollow square tube is fixedly connected to the inside of the fixing sleeve. One end of the hollow square tube is located inside the pickling tank, and an embedded tube is inserted into the end of the hollow square tube away from the pickling tank. When some pickling solution flows into the lower end of the hollow square tube, the liquid level of the pickling solution becomes level with the liquid level of the pickling solution inside the hollow square tube. Similarly, the liquid level of the pickling solution will drop accordingly, so as to achieve the effect of immersing and pickling the surface of the angle steel in stages. That is to say, the part of the angle steel immersed in the pickling solution needs to be pickled more thoroughly than the part not immersed in the pickling solution.

[0008] Preferably, the impurity remover includes a flow limiting plate, which is fixedly installed on the surface of the pickling tank. An external ring is provided on the side of the flow limiting plate, and one side of the external ring is fixedly connected to the pickling tank.

[0009] Preferably, a spring is fixedly connected inside the peripheral ring, and a movable strip is fixedly connected to the end of the spring away from the peripheral ring. The movable strip is slidably installed inside the peripheral ring.

[0010] Preferably, a crossbar is fitted around the outer side of the moving strip, and side plates are fixedly connected to both ends of the crossbar. A pressure grinding die is fixedly connected to the bottom of the side plates. As the spring continuously pulls downwards, the moving strip slides downwards along the inside of the outer ring. The moving strip then drives the side plates fixed at both ends to move downwards. Since the bottom of the side plates is fixedly connected to the pressure grinding die, the downward-moving pressure grinding die adheres to the surface of the angle steel, thus scraping away acidic substances and burrs generated during processing.

[0011] Preferably, the end of the external ring away from the pickling tank is provided with a plug plate, and a retaining strip is fixedly connected to the inner side of the plug plate, with the retaining strip placed directly opposite the flow limiting plate.

[0012] Preferably, a first tension piece is fixedly connected to the top of the hollow square tube, and the end of the first tension piece away from the hollow square tube is fixedly connected to the pickling tank. A partition is fixedly connected to the center of the hollow square tube. Furthermore, both the first and second tension pieces are elastic, and their function is to prevent the liquid inside the pickling tank from flowing out due to the up-and-down movement of the hollow square tube.

[0013] Preferably, a second stretching plate is fixedly connected to the bottom of the hollow square tube, and the end of the second stretching plate away from the hollow square tube is fixedly connected to the pickling tank.

[0014] Preferably, the anti-stacking device includes a turning roller, which is rotatably mounted on the outside of the galvanizing bath. A transmission box is fixedly mounted at one end of the turning roller, and a motor is fixedly mounted on the side of the transmission box away from the turning roller. When it slides to the other end, it continues to move forward with the turning roller, repeating the cycle to keep the hot zinc around the angle steel in a continuous flow, thus maintaining the constant replacement of hot zinc, increasing the contact area between the angle steel and the hot zinc, and improving the freshness of the hot zinc.

[0015] Preferably, a bearing sleeve is fastened to the bottom side of the tilting roller, a bottom block is fixedly connected to the bottom side of the bearing sleeve, a top frame is fixedly connected to the end of the bottom block away from the bearing sleeve, a hollow platform is fixedly connected to the bottom of the top frame, and the hollow platform is fixedly installed inside the galvanizing tank.

[0016] Preferably, a connecting piece is fixedly connected to the outer side of the bearing sleeve, a hollow column is fixedly connected to the bottom of the connecting piece, a tough block is provided at the bottom of the hollow column, and the tough block is fixedly installed inside the top frame.

[0017] Preferably, the bottom of the tough block is provided with an impact post, and a first magnetic block is fixedly connected to the outer side of the impact post. A housing is slidably mounted on both the first magnetic block and the outer side of the impact post. A second magnetic block is fixedly connected to the bottom of the inner side of the housing, and the bottom of the housing is fixedly connected to the hollow platform. When the tough block is flipped to the outside of the impact post and is not compressed but rather attached to its outer side, the impact post will quickly extend upwards due to the repulsive force between the first and second magnetic blocks. Subsequently, the impact post will strike the angle steel positioned at its top, thereby reversing the angle steel and separating the two.

[0018] This invention provides a hot-dip galvanizing device for the surface of angle steel used in power transmission towers. It has the following beneficial effects:

[0019] 1. The hot-dip galvanizing equipment for the angle steel surface of this power tower compresses the air in the space created by the bottom of the plug and the movable bladder, causing the lower half of the movable bladder to remain bulging. This seals the five movable bladders together, preventing acidic liquid from flowing out when the angle steel is inserted into the pickling tank through the movable bladders. In addition, the squeezing and friction of the movable bladders on the angle steel can pre-clean the surface of the angle steel.

[0020] II. The hot-dip galvanizing equipment for the angle steel surface of this power transmission tower works by placing the upper end of the hollow square tube above the pickling solution and the lower end of the hollow square tube inside the pickling solution. At this time, some of the pickling solution in the pickling tank will flow into the lower end of the hollow square tube, eventually reaching a state where the liquid level of the pickling solution in the hollow square tube is the same as that in the tube. Similarly, the liquid level of the pickling solution will drop accordingly, so as to achieve the effect of immersing and pickling the surface of the angle steel step by step. That is to say, the part of the angle steel immersed in the pickling solution needs to be pickled more thoroughly than the part not immersed in the pickling solution.

[0021] Third, when the hot-dip galvanizing equipment for the angle steel surface of the power tower moves to the top of the slide rail through the hollow square tube, both the upper and lower ends of the hollow square tube are above the surface of the pickling solution. At this time, the height of the pickling solution will remain unchanged, and the entire angle steel will be immersed in the pickling solution for pickling.

[0022] Fourth, when the hot-dip galvanizing equipment for the angle steel surface of the power tower moves to the lowest end of the slide rail through the hollow square tube, both the upper and lower ends of the hollow square tube will be submerged in the pickling solution. At this time, part of the pickling solution will flow into the hollow square tube to replenish it, and the liquid level will drop, so as to expose the angle steel from the pickling solution, making it easier for operators to observe and carry out subsequent operations.

[0023] 5. The hot-dip galvanizing equipment for the angle steel surface of the power tower works by the spring continuously pulling the angle steel downward during the extraction process, causing the moving bar to slide downward along the inside of the outer ring. Subsequently, the moving bar will drive the side plates fixed at both ends to move downward, and the bottom of the side plates is fixedly connected to the pressure grinding mold. Therefore, the downward moving pressure grinding mold will adhere to the surface of the angle steel to remove acidic substances and burrs generated during processing.

[0024] VI. The hot-dip galvanizing equipment for the angle steel surface of this power transmission tower works by the fact that when the angle steel moves to either end, its own weight is greater than the frictional force of the turning roller, so the angle steel will move in the opposite direction due to gravity. However, when it slides to the other end, it will continue to move in the forward direction with the turning roller, repeating the cycle to keep the hot zinc around the angle steel in a continuous state of flow and replacement, thereby increasing the contact area between the angle steel and the hot zinc and the freshness of the hot zinc.

[0025] VII. The hot-dip galvanizing equipment for the angle steel surface of the power tower works by having the tough block flipped to the outside of the impact column and attached to its outside without squeezing it. The impact column will then extend upward rapidly due to the repulsive force between the first and second magnetic blocks. Subsequently, the impact column will strike the angle steel set at the top of it, so as to knock the angle steel backward and separate the two. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0037] First embodiment, such as Figures 1-4 As shown, the present invention provides a technical solution: a hot-dip galvanizing equipment for the surface of angle steel of power transmission towers, including a pickling tank 1, a regulator 2, a remover 3, and a limiter 4. The regulator 2 is fixedly installed on the outside of the pickling tank 1, and the remover 3 is fixedly installed on the outside of the regulator 2. The positional relationship between the remover 3 and the regulator 2 is at a 90° angle. The limiter 4 is fixedly installed on the side of the pickling tank 1 away from the remover 3. A support rod 5 is fixedly connected to the bottom of the pickling tank 1, and a galvanizing tank 6 is fixedly connected to the outside of the support rod 5. A stacking device 7 is fixedly installed inside the galvanizing tank 6.

[0038] The limiter 4 includes a current tube 41, the outer side of which is sleeved on the outer side of the pickling tank 1. The inner end of the current tube 41 is connected to a flow ring 42, and the inner side of the flow ring 42 is connected to an electromagnet 43. A magnetic shielding sleeve 44 is fixedly connected to the outer side of the electromagnet 43. A vertical plate 45 is fixedly connected to the inner side of the magnetic shielding sleeve 44. A fixed rail 40 is fixedly connected to the inner side of the vertical plate 45. A traction sleeve 48 is slidably installed inside the fixed rail 40. A sliding rod 46 is fixedly connected to the inner side of the traction sleeve 48. A pressure plug 49 is fixedly connected to the bottom of the sliding rod 46. A movable bladder 47 is squeezed and adapted to the outer side of the pressure plug 49.

[0039] By inserting the angle steel into the sealed body composed of five movable bladders 47, gaps are created between the five movable bladders 47, allowing the angle steel to pass through. The lower half of the movable bladder 47 is elastic, and the pressure plug 49 slidably installed inside it is in a downward trend. Therefore, the air in the space created by the bottom of the pressure plug 49 and the movable bladder 47 is compressed, ultimately causing the lower half of the movable bladder 47 to remain bulging, keeping the five movable bladders 47 in a sealed state. This prevents acidic liquid from flowing out when the angle steel is inserted into the pickling tank 1 through the movable bladders 47. In addition, the squeezing and friction of the angle steel by the movable bladders 47 can play a role in pre-cleaning the surface of the angle steel.

[0040] When current is supplied to the current tube 41 from the outside, the connected flow ring 42 transmits the power to the electromagnet 43, causing the electromagnet 43 to generate magnetic force. At this time, the traction sleeve 48, which is slidably installed inside the fixed rail 40, will slide downwards along its interior. Because the inner side of the traction sleeve 48 is fixedly connected to the sliding rod 46, and the sliding rod 46 is made of a magnetic material, the pressure plug 49 fixed at the bottom of the sliding rod 46 will continue to move downwards. In addition, the magnetic shielding sleeve 44 serves to isolate the magnetic force generated by the electromagnet 43.

[0041] Second embodiment, such as Figures 5-9 As shown, the regulator 2 includes a slide rail 21, which is fixedly installed on the outside of the pickling tank 1. A slider 22 is slidably installed on the outside of the slide rail 21. A fixing sleeve 23 is fitted on the surface of the slider 22. A hollow square tube 24 is fixedly connected to the inside of the fixing sleeve 23. One end of the hollow square tube 24 is located inside the pickling tank 1. An embedded tube 25 is inserted into the end of the hollow square tube 24 away from the pickling tank 1. A first stretching piece 26 is fixedly connected to the top of the hollow square tube 24. The end of the first stretching piece 26 away from the hollow square tube 24 is fixedly connected to the pickling tank 1. A partition 27 is fixedly connected to the center of the hollow square tube 24. A second stretching piece 28 is fixedly connected to the bottom of the hollow square tube 24. The end of the second stretching piece 28 away from the hollow square tube 24 is fixedly connected to the pickling tank 1.

[0042] By sliding the slider 22 downwards along the slide rail 21, the fixed sleeve 23, which is fixedly connected to it, will move the hollow square tube 24 downwards together, so that the upper end of the hollow square tube 24 is above the pickling solution, while the lower end of the hollow square tube 24 is in the pickling solution. At this time, some of the pickling solution in the pickling tank 1 will flow into the lower end of the hollow square tube 24, eventually reaching a state where the liquid level of the pickling solution is the same as the liquid level of the pickling solution in the hollow square tube 24. Similarly, the liquid level of the pickling solution will drop accordingly, so as to achieve the effect of immersing and pickling the surface of the angle steel step by step. That is to say, the part of the angle steel immersed in the pickling solution needs to be pickled more thoroughly than the part not immersed in the pickling solution.

[0043] Similarly, when the hollow square tube 24 moves to the top of the slide rail 21, both the upper and lower ends of the hollow square tube 24 are above the surface of the pickling solution. At this time, the height of the pickling solution will remain unchanged, and the entire angle steel will be immersed in the pickling solution for pickling.

[0044] However, when the hollow square tube 24 moves to the lowest end of the slide rail 21, both the upper and lower ends of the hollow square tube 24 will be submerged in the pickling solution. At this time, part of the pickling solution will flow into the hollow square tube 24 to replenish it, and its liquid level will drop, so as to expose the angle steel from the pickling solution, making it easier for operators to observe and carry out subsequent operations.

[0045] The embedded tube 25, inserted inside the hollow square tube 24, increases the internal volume of the hollow square tube 24 when pulled outward, allowing more pickling solution to flow in and increasing the drop distance of the pickling solution level. Additionally, the first stretching plate 26 and the second stretching plate 28 are elastic, preventing liquid inside the pickling tank 1 from flowing out due to the up-and-down movement of the hollow square tube 24.

[0046] The impurity remover 3 includes a flow-limiting disc 37, which is fixedly installed on the surface of the pickling tank 1. An outer ring 31 is provided on the side of the flow-limiting disc 37. One side of the outer ring 31 is fixedly connected to the pickling tank 1. A spring 32 is fixedly connected inside the outer ring 31. A moving strip 33 is fixedly connected to the end of the spring 32 away from the outer ring 31. The moving strip 33 is slidably installed inside the outer ring 31. A crossbar 34 is sleeved on the outside of the moving strip 33. Side plates 35 are fixedly connected to both ends of the crossbar 34. A pressure mold 36 is fixedly connected to the bottom of the side plate 35. An insertion plate 38 is provided at the end of the outer ring 31 away from the pickling tank 1. A retaining strip 39 is fixedly connected to the inner side of the insertion plate 38. The retaining strip 39 is placed facing the flow-limiting disc 37.

[0047] After pickling, the angle steel is pulled out from the center of the flow-limiting plate 37 and squeezes the retaining strip 39 that was initially inserted into the flow-limiting plate 37. The retaining strip 39 and the insert plate 38 block the flow-limiting plate 37 to prevent the pickling solution from flowing out. In addition, during the extraction process, the spring 32 is continuously stretched downward, causing the moving strip 33 to slide downward along the inside of the outer ring 31. Then the moving strip 33 drives the side plates 35 fixed at both ends to move downward. The bottom of the side plates 35 is fixedly connected to the pressure grinding mold 36. Therefore, the downward moving pressure grinding mold 36 will adhere to the surface of the angle steel to scrape off the acidic substances and burrs generated during processing.

[0048] In addition, when the surface of the angle steel is difficult to clean or uneven, the angle steel will press the pressure mold 36 in the opposite direction. At this time, the spring 32 will compress upward, so that the pressure mold 36 avoids contact with this section as much as possible, thereby reducing the wear on the pressure mold 36.

[0049] The stacking device 7 includes a turning roller 72, which is rotatably mounted on the outside of the galvanizing tank 6. A transmission box 73 is fixedly mounted on one end of the turning roller 72. A motor 74 is fixedly mounted on the side of the transmission box 73 away from the turning roller 72. A bearing sleeve 76 is fastened to the bottom side of the turning roller 72. A bottom block 77 is fixedly connected to the bottom side of the bearing sleeve 76. A top frame 71 is fixedly connected to the end of the bottom block 77 away from the bearing sleeve 76. A hollow platform 75 is fixedly connected to the bottom of the top frame 71. The hollow platform 75 is fixedly installed inside the galvanizing tank 6. The bearing sleeve 76... A connecting piece 78 is fixedly connected to the outside of 6. A hollow column 79 is fixedly connected to the bottom of the connecting piece 78. A tough block 70 is provided at the bottom of the hollow column 79. The tough block 70 is fixedly installed inside the top frame 71. An impact column 701 is provided at the bottom of the tough block 70. A first magnetic block 702 is fixedly connected to the outside of the impact column 701. A housing 703 is slidably installed on the outside of both the first magnetic block 702 and the impact column 701. A second magnetic block 704 is fixedly connected to the bottom of the inner side of the housing 703. The bottom of the housing 703 is fixedly connected to the hollow platform 75.

[0050] Finally, the angle steel is placed on the turning roller 72, and then the motor 74 is started, causing multiple turning rollers 72 to rotate in the same direction through the transmission box 73. At this time, the angle steel will slide along the direction of rotation of the turning roller 72. The turning roller 72 is set up with the two sides higher and the middle lower. Therefore, when the angle steel moves to either end, its own weight is greater than the friction force of the turning roller 72, so the angle steel will move in the opposite direction due to gravity. However, when it slides to the other end, it will continue to move in the forward direction with the turning roller 72. This cycle repeats to keep the hot zinc around the angle steel in a state of constant flow, keeping the hot zinc in a state of constant replacement, increasing the contact area between the angle steel and the hot zinc and the freshness of the hot zinc.

[0051] When some angle steel overlaps, the combined gravity of the two components compresses and squeezes the turning roller 72. The turning roller 72 is flexible and rotatably mounted on the bearing sleeve 76. The bottom block 77 fixed to the bottom of the bearing sleeve 76 is also flexible, and a connecting piece 78 is fixedly connected to the outer side of the bearing sleeve 76. Therefore, the hollow column 79 fixed to the bottom of the connecting piece 78 moves downwards and squeezes the flexible block 70. The flexible block 70 is flexible and has a fast recovery speed. At this point, the flexible block 70... The impact column 701 bends downward and compresses the impact column 701. Then the impact column 701 moves downward along the inner wall of the housing 703 until it contacts the second magnetic block 704. However, when the tough block 70 flips to the outside of the impact column 701 and does not compress it but attaches to its outside, the impact column 701 will quickly extend upward due to the repulsive force between the first magnetic block 702 and the second magnetic block 704. Then the impact column 701 will impact the angle steel set at the top of it, so as to knock the angle steel backward and separate the two.

[0052] Then, by impacting the column 701 with its own gravity, it will return to its original position, and the tough block 70 will also quickly return to its closed state.
