[0002] Hot dip galvanizing (galvanizing) is also called hot dip zinc plating and hot dip galvanizing: it is an effective way of metal anti-corrosion, mainly used for metal structure facilities in various industries. It is to immerse the rust-removed steel parts into the molten zinc liquid at about 500 °C, so that the zinc layer adheres to the surface of the steel components, thereby achieving the purpose of anti-corrosion. The technological process of hot dip galvanizing: finished product pickling - water washing - adding flux - drying - hanging plating - cooling - chemical treatment - cleaning - grinding - completion of hot dip galvanizing. Hot dip galvanizing has developed from the older hot plating method. Since it was applied in industry in France in 1836, it has a history of more than one hundred and seventy years. In the past thirty years, with the rapid development of cold-rolled strip steel, the hot dip galvanizing industry has developed on a large scale.

[0003] In the prior art during the use of the device for draining zinc from hot dip galvanized steel pipes, there is also a problem that the steel pipes are blocked by partitions, resulting in mutual friction between the steel pipes and the partitions, thus causing damage to the steel pipes and the partitions, and further making the device unable to be used. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for draining zinc from hot dip galvanized steel pipes, so as to solve the problem in the prior art that during the use of the device for draining zinc from hot dip galvanized steel pipes, there is also a situation where the steel pipes are blocked by partitions, resulting in mutual friction between the steel pipes and the partitions, thus causing damage to the steel pipes and the partitions, and further making the device unable to be used.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for draining zinc from hot dip galvanized steel pipes, including two symmetrically arranged support plates, the tops of both support plates are fixedly installed with uniformly distributed fixing blocks, the tops of one sides of both support plates are fixedly installed with upwardly inclined feeding plates, the tops of the other sides of both support plates are fixedly installed with downwardly inclined discharging plates, and steel pipes are placed on the feeding plates;

[0006] Two symmetric first gears are rotatably installed on the outer sides of the two support plates. Three uniformly distributed second gears are rotatably installed between the two first gears. The first gears and the second gears are meshed and driven in sequence. A first rotating roller is rotatably installed at a position corresponding to the center of the first gears between the two support plates. A second rotating roller is rotatably installed on the inner side of one of the support plates. A driving motor is provided at a position corresponding to the second rotating roller on the inner side of the support plate. The output end of the driving motor is fixedly connected to the central shaft of the second rotating roller. The first rotating roller and the second rotating roller are connected by a belt drive. A connecting rod is rotatably installed between the two first gears. Uniformly distributed supporting blocks are fixedly installed at the top of the connecting rod.

[0007] Wherein, an arc-shaped groove matching the outer wall radian of the steel pipe is provided at the top of the supporting block.

[0008] Wherein, the top of the fixing block is semi-circular arc-shaped, and the gap between the tops of adjacent two fixing blocks is larger than the size of the steel pipe.

[0009] Wherein, during the counterclockwise rotation of the two first gears, when the bottom end of the connecting rod is at the highest position of the first gear, the height of the supporting block is higher than the height of the fixing block.

[0010] Wherein, during the counterclockwise rotation of the two first gears, when the bottom end of the connecting rod is at the leftmost position of the first gear, the height of the supporting block is lower than the height of the fixing block.

By starting the driving motor, while the second rotating roller drives the first rotating roller to rotate, the first gears on both sides of the support plate also rotate synchronously, thereby driving the second gears and the remaining first gears to rotate. The connecting rods rotatably connected to the two first gears on the same side drive the supporting blocks to rotate synchronously. When the connecting rod moves counterclockwise following the first gear, the supporting block closest to the feeding plate lifts the steel pipe at the bottom end of the feeding plate and moves it to the fixing blocks on both sides. While the steel pipe at the bottom end of the feeding plate is removed, due to the inclined setting of the feeding plate, the steel pipe will automatically slide to the bottom end of the feeding plate. The remaining supporting blocks repeat the above process to move the steel pipes to the fixing blocks in sequence. During the whole process, the friction of the steel pipes is minimized to ensure the best hot-dip galvanizing state of the steel pipes. Description of the Drawings

Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a hot-dip galvanized zinc draining device for steel pipes, including two symmetrically arranged support plates 10. Uniformly distributed fixing blocks 20 are fixedly installed at the tops of the two support plates 10. An upwardly inclined feeding plate 11 is fixedly installed at the top of one side of the two support plates 10. A downwardly inclined discharging plate 12 is fixedly installed at the top of the other side of the two support plates 10. A steel pipe 30 is placed on the feeding plate 11. The feeding plate 11 is inclined, and the steel pipe 30 will automatically slide to the bottom end of the feeding plate 11. Uniformly distributed fixing blocks 20 are fixedly installed at the tops of the two support plates 10. The fixing blocks 20 are provided to support the steel pipe 30;

[0020] Two symmetrical first gears 40 are rotatably installed on the outer sides of the two support plates 10, and three evenly distributed second gears 50 are rotatably installed between the two first gears 40. The first gears 40 and the second gears 50 are meshed and transmitted in sequence. A first rotating roller 90 is rotatably installed at a position corresponding to the center of the first gear 40 between the two support plates 10, and a second rotating roller 91 is rotatably installed on the inner side of one of the support plates 10. A driving motor 60 is provided at a position corresponding to the second rotating roller 91 on the inner side of the support plate 10, and an output end of the driving motor 60 is fixedly connected to the central axis of the second rotating roller 91. The first rotating roller 90 and the second rotating roller 91 are connected to the first rotating roller 90 and the second rotating roller 91. The two rotating rollers 91 are connected by a belt 92, a connecting rod 70 is rotatably installed between the two first gears 40, and evenly distributed supporting blocks 80 are fixedly installed on the top of the connecting rod 70. The first rotating roller 90 and the second rotating roller 91 are connected by a belt 92, and the driving motor 60 is started. While the second rotating roller 91 drives the first rotating roller 90 to rotate, the first gears 40 on both sides of the support plate 10 also rotate synchronously, thereby driving the second gear 50 and the remaining first gears 40 to rotate, and the connecting rod 70 rotatably connected on the two first gears 40 on the same side also rotates synchronously with the supporting blocks 80.

[0021] Among them, the top of the supporting block 80 is provided with an arc groove matching the curvature of the outer wall of the steel pipe 30. Due to the circular structure of the steel pipe 30, an arc surface matching the size of the steel pipe 30 is provided to cooperate with it, so that the structure of the supporting block 80 is stable when moving the steel pipe 30.

[0022] The top of the fixing block 20 is semicircular, and the gap between the tops of two adjacent fixing blocks 20 is larger than the size of the steel pipe 30, so that the two adjacent fixing blocks 20 can support the steel pipe 30 and maintain the structural stability of the steel pipe 30.

[0023] Among them, when the two first gears 40 rotate counterclockwise, when the bottom end of the connecting rod 70 is located at the highest point of the first gear 40, the height of the supporting block 80 is higher than the height of the fixed block 20, and the supporting block 80 closest to the feed plate 11 lifts the steel pipe 30 at the bottom end of the feed plate 11 and moves it to the fixed blocks 20 on both sides. The steel pipe 30 at the bottom end of the feed plate 11 is removed to reduce friction.

[0024] Among them, during the counterclockwise rotation of the two first gears 40, when the bottom end of the connecting rod 70 is located at the leftmost position of the first gear 40, the height of the supporting block 80 is lower than the height of the fixed block 20, and the supporting block 80 closest to the feed plate 11 lifts the steel pipe 30 at the bottom end of the feed plate 11 and moves it to the fixed blocks 20 on both sides. The steel pipe 30 at the bottom end of the feed plate 11 is removed to reduce friction.

[0025] Among them, both ends of the first rotating roller 90 are fixedly connected to the centers of two first gears 40 at the tail end. By arranging that the first rotating roller 90 and the second rotating roller 91 are rotationally connected by a belt 92, when the driving motor 60 is started and the second rotating roller 91 drives the first rotating roller 90 to rotate, the first gears 40 on both sides of the support plate 10 also rotate synchronously.

[0026] Working principle: During use, by arranging that the first rotating roller 90 and the second rotating roller 91 are rotationally connected by a belt 92, when the driving motor 60 is started and the second rotating roller 91 drives the first rotating roller 90 to rotate, the first gears 40 on both sides of the support plate 10 also rotate synchronously, thereby driving the second gear 50 and the remaining first gears 40 to rotate. The connecting rods 70 rotatably connected to the two first gears 40 on the same side also drive the supporting blocks 80 to rotate synchronously. When the connecting rods 70 move counterclockwise following the first gears 40, the supporting block 80 closest to the feeding plate 11 lifts the steel pipe 30 at the bottom end of the feeding plate 11 and moves it to the fixing blocks 20 on both sides. While the steel pipe 30 at the bottom end of the feeding plate 11 is removed, since the feeding plate 11 is inclined, the steel pipe 30 will automatically slide to the bottom end of the feeding plate 11. The remaining supporting blocks 80 repeat the above process to move the steel pipes 30 to the fixing blocks 20 in sequence. During the whole process, the friction of the steel pipes 30 is minimized to ensure the best hot-dip galvanizing state of the steel pipes 30.

[0027] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
