[0002] Galvanized steel pipe refers to a welded steel pipe with a hot-dip or electroplated zinc layer on the surface. Galvanizing steel pipes can increase the corrosion resistance of steel pipes and extend their service life. They are widely used in manufacturing industries such as construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, and greenhouse construction. Galvanized pipes have a wide range of uses. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, oil heaters, condenser coolers, coal distillation and washing oil exchangers for chemical coking equipment, and pier pipe piles and support frames for mine tunnels.

[0003] During the production and manufacturing process of steel pipes, high-temperature steel pipes need to be cooled.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See attached Figure 1-5 , a galvanized steel pipe forming and cooling device, comprising:

[0032] The water tank 1 has an annular chute 2 on the inner wall of the front and rear baffles, and an escape groove 3 connected to the annular chute 2 is provided above the annular chute 2; a plurality of supporting legs 18 and a drain port 19 are provided at the bottom of the water tank 1, the supporting legs 18 prop up the water tank 1, and the drain port 19 is used to drain the water in the water tank 1;

[0033] The driving motor 4 is arranged outside the rear baffle of the water tank 1 and is used to drive the turntable 5 to drive the steel pipe to rotate; the output shaft of the driving motor 4 penetrates the rear baffle of the water tank 1 inwardly;

[0034] Two turntables 5 are arranged inside the water tank 1 and connected by a transmission shaft 6; a raised key plate 15 is arranged on the outer wall of the transmission shaft 6, and a key groove which is interference fit with the key plate 15 is opened on the turntable 5; one end of the transmission shaft 6 is connected to the output shaft of the driving motor 4, and the other end is rotatably connected to the inner wall of the front baffle of the water tank 1; the two turntables 5 are respectively close to the inner walls of the front and rear baffles of the water tank 1, and a plurality of slots 7 are arranged at intervals on their outer circles; a limiting slot 8 is arranged on one side of the slot 7 close to the front and rear baffles of the water tank 1, and a limiting plate 9 is arranged in the limiting slot 8; the limiting plate 9 is hollow inside, and a semicircular notch is arranged at the bottom, and a slide plate 10 which is slidably matched with the annular slide groove 2 is also arranged on the top thereof; because the slide plate 10 rotates in the annular slide groove 2, the limiting plate 9 can well resist the steel pipe to keep the structure stable during the rotation process;

[0035] A pressure plate 11 is provided above the front and rear baffles of the water tank 1 ; a downwardly protruding stopper 12 is provided at the bottom of the pressure plate 11 , and the stopper 12 is located in the avoidance groove 3 ; the bottom of the stopper 12 is an arc-shaped surface.

[0036] In this embodiment, two vertical guide posts 13 are respectively provided on the top of the front and rear baffles of the water tank 1; and a guide groove 14 corresponding to the position of the guide post 13 is provided on the pressing plate 11. After the guide groove 14 on the pressing plate 11 is aligned with the guide post 13, the pressing plate 11 is lowered, so that the stopper 12 under the pressing plate 11 can just enter the avoidance groove 3.

[0037] In addition, the front and rear baffles of the water tank 1 are higher than the two side plates, and arc-shaped water baffles 16 are arranged above the two side plates to block the splashes of water during the rotation of the steel pipe. A plurality of exhaust fans 17 are arranged on the front baffle of the water tank 1, and the installation height of the exhaust fans 17 is higher than the two side plates of the water tank 1 to accelerate the air flow in the water tank 1, which is conducive to accelerating the cooling of the steel pipe.

[0038] It should be noted that the edge of the slot 7 of the turntable 5 is also chamfered to facilitate the lowered steel pipe to enter the slot 7 smoothly.

[0039] In actual use, the steel pipe is lifted to the top of the water tank 1, and then lowered after adjusting the angle. Before lowering the steel pipe, the pressure plate 11 on the front and rear baffles of the water tank 1 must be removed; after the steel pipe enters the slot 7, the limit plate 9 is placed into the limit groove 8 on the side of the slot 7 at the corresponding position, so that the semicircular notch at the bottom of the limit plate 9 is against the steel pipe, and the slide plate 10 at the top of the limit plate 9 is just located in the annular slide groove 2. Start the drive motor 4, drive the transmission shaft 6 and the turntable 5 to rotate a certain angle, so that the other slot 7 on the turntable 5 rotates to the position below the avoidance groove 3, which is convenient for another steel pipe below. Repeat the above steps until a steel pipe is placed in the inner bucket of each slot 7 on the turntable 5, and then lower the pressure plate 11 along the guide groove 14, so that the block 12 under the pressure plate 11 enters the avoidance groove 3, to avoid the situation where the slide plate 10 at the top of the limit plate 9 is stuck under the avoidance groove 3 during the rotation process.

[0040] The water level in the water tank 1 does not exceed the height of the two side plates of the water tank 1. When the driving motor 4 continues to work, the steel pipes on the turntable 5 alternately enter under the water surface, and then turn out from the water surface to contact with the air for heat exchange. At the same time, under the action of the exhaust fan 17, the high-temperature air in the water tank 1 can be quickly discharged, so that the cold air outside the water tank 1 can be quickly replenished into the water tank 1, which is beneficial to accelerate the cooling of the steel pipes and improve the cooling efficiency.

[0041] The galvanized steel pipe forming cooling device of the present invention can cool multiple steel pipes simultaneously in a water pool of limited size by rotating the turntable 5, solving the problem in the prior art that the number of cooled steel pipes is limited by the size of the water pool. The steel pipes are cooled not only by the water in the water pool but also by accelerating the heat exchange between the steel pipes and the air. The cooling efficiency is significantly improved, the device is very practical, and has good market application prospects.

[0042] The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the utility model and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the utility model and various different options and changes.
