Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] This utility model discloses a steel pipe sizing and cooling device for steel pipe production, such as... Figures 1-7 As shown, the system includes a cooling platform 1 and a water tank 2 located on the left side of the outer surface of the cooling platform 1. The water tank 2 is used to store water for cooling the steel pipe. A fixing frame 3 is fixedly installed on the outer top surface of the cooling platform 1, and a dispersion pipe 6 is fixedly installed on the inner top surface of the fixing frame 3. Multiple first spray heads 4 are fixedly installed on the outer bottom surface of the dispersion pipe 6. After the water in the water tank 2 enters the dispersion pipe 6, it will enter the multiple first spray heads 4 respectively, and be sprayed onto the outer surface of the steel pipe through the multiple first spray heads 4 to cool the steel pipe.

[0027] Electric slide rails 2011 are fixedly installed on both the left and right sides of the opening on the top surface of the cooling platform 1, and support plates 2012 are fixedly installed on the top surface of the sliders of the two electric slide rails 2011. The sliders of the two electric slide rails 2011 can drive the two support plates 2012 to move along the electric slide rails 2011 to adjust the distance between the two support plates 2012.

[0028] Each of the two support plates 2012 has a fixed block 2015 rotatably connected to one side of its opposite side. The steel pipe is placed between the two fixed blocks 2015, and then the two support plates 2012 are brought closer to each other, so that the two fixed blocks 2015 clamp and fix the two ends of the steel pipe.

[0029] Furthermore, a second gear 2014 is fixedly installed on one side of the outer surface of each of the two fixing blocks 2015. When the second gear 2014 rotates, it will drive the fixing block 2015 to rotate.

[0030] Each of the two support plates 2012 has a third gear 2016 rotatably connected to one side of the opposite side, and the two third gears 2016 mesh with the two second gears 2014 respectively. A second motor 2013 is fixedly installed on the side of each of the two support plates 2012 away from the fixed block 2015. The second motor 2013 is powered by an external power source.

[0031] Furthermore, the output shafts of the two second motors 2013 are fixedly connected to the two third gears 2016 respectively. The second motors 2013 drive the third gears 2016 to rotate, which in turn drives the second gears 2014 and the fixing blocks 2015 to rotate, thereby causing the steel pipe clamped and fixed by the two fixing blocks 2015 to rotate, so that water can be sprayed evenly on the outer surface of the steel pipe.

[0032] A second spray head 207 is fixedly installed on one side of the two support plates 2012, and one of the fixing blocks 2015 is sleeved on the outer surface of the second spray head 207. When the two fixing blocks 2015 clamp and fix the steel pipe, the second spray head 207 will be inserted into the inside of the steel pipe, and water will be sprayed into the inside of the steel pipe.

[0033] A water pump 202 is fixedly installed on one side of the outer surface of the water tank 2. The water pump 202 is powered by an external power source. When it is powered on, the motor of the water pump 202 will drive the impeller to rotate. The high-speed rotation of the impeller generates centrifugal force, which throws the liquid out of the center of the impeller, forming a low-pressure zone to draw in the liquid. At the same time, the liquid gains kinetic energy and pressure energy to complete the liquid transfer.

[0034] Furthermore, a connecting pipe 201 is fixedly connected between the inlet of the water pump 202 and the water tank 2, and a transmission pipe 203 is fixedly installed at the outlet of the water pump 202. A tee 204 is fixedly installed at the end of the transmission pipe 203 away from the water pump 202. An input pipe 205 is fixedly installed at one outlet of the tee 204, and a fixed pipe 206 is fixedly connected to the other outlet of the tee 204. The input pipe 205 is fixedly connected to the dispersion pipe 6, and the fixed pipe 206 is rotatably connected to the second spray head 207. The water pump 202 can transmit water in the water tank 2 to the first spray head 4 and the second spray head 207 to cool the outside and inside of the steel pipe.

[0035] The cooling platform 1 has three filter plates 101 fixedly installed inside. The filter holes of the three filter plates 101 are of different sizes so as to perform multi-layer filtration of water containing impurities after spraying.

[0036] Three movable rods 102 are slidably connected to the rear side of the outer surface of the cooling platform 1. Parts of the three movable rods 102 are located inside the cooling platform 1, and the other parts of the three movable rods 102 are located outside the cooling platform 1. A brush plate 104 is fixedly installed at one end of the three movable rods 102 inside the cooling platform 1. When the three movable rods 102 move, they will drive the three brush plates 104 to move.

[0037] Furthermore, the three brush plates 104 are located above the three filter plates 101 respectively. When the brush plates 104 move, they will wipe the filter plates 101 to clean the impurities remaining on the filter plates 101.

[0038] A sealing door 107 is hinged to one side of the outer surface of the cooling platform 1. Opening the sealing door 107 allows the cleaned impurities to be discharged from the cooling platform 1.

[0039] The three movable rods 102 are fixedly mounted on a connecting plate 103 at one end outside the cooling platform 1. When the connecting plate 103 is pushed to move, the three movable rods 102 can be moved at the same time.

[0040] The drive assembly includes a guide frame 1031 fixedly mounted on one side of the outer surface of the cooling platform 1, and a connecting plate 103 slidably connected to the guide frame 1031, and the connecting plate 103 can move along the guide frame 1031.

[0041] A connecting rod 1036 is rotatably connected to the outer surface of the cooling platform 1 on one side of the connecting plate 103. A reciprocating screw 1032 is fixedly installed at the end of the connecting rod 1036 away from the cooling platform 1. When the connecting rod 1036 rotates, it will drive the reciprocating screw 1032 to rotate. The reciprocating screw 1032 is rotatably connected to the guide frame 1031. The connecting plate 103 is located on the outer surface of the reciprocating screw 1032. When the connecting rod 1036 drives the reciprocating screw 1032 to rotate, the connecting plate 103 will move back and forth along the guide frame 1031, thereby driving the three movable rods 102 and the three brush plates 104 to move back and forth, so that the three brush plates 104 repeatedly wipe the three filter plates 101.

[0042] A first bevel gear 1033 is fixedly installed on one side of the outer surface of the connecting rod 1036. A micro motor 1035 is fixedly installed on the outer surface of the cooling platform 1 on one side of the connecting rod 1036. The micro motor 1035 is powered by an external power source, and a second bevel gear 1034 is fixedly installed on the output shaft of the micro motor 1035. The second bevel gear 1034 meshes with the first bevel gear 1033. When the micro motor 1035 is powered on, it will drive the second bevel gear 1034 to rotate. The rotating second bevel gear 1034 will drive the first bevel gear 1033 to rotate, which will cause the connecting rod 1036 to rotate.

[0043] A baffle 1017 is provided at the connection between the connecting rod 1036 and the reciprocating lead screw 1032.

[0044] A connecting pipe 106 is fixedly installed inside the cooling platform 1, and the connecting pipe 106 is connected to the water tank 2. The filtered water will fall into the interior of the cooling platform 1 for sedimentation. The sedimented water can enter the water tank 2 through the connecting pipe 106 for reuse.

[0045] The cooling platform 1 has two rotating shafts 1011 rotatably connected to both sides inside. Each of the two rotating shafts 1011 has a baffle 1017 fixedly installed on the outer surface of the two rotating shafts 1011 on one side inside the cooling platform 1. The height of the two baffles 1017 is less than the height of the connecting pipe 106. When the rotating shafts 1011 rotate, they will drive the baffles 1017 to rotate. When the two baffles 1017 rotate to the vertical position, the baffle 1017 on one side of the connecting pipe 106 will block the opening of the connecting pipe 106. When the two baffles 1017 rotate to the horizontal position, they will no longer block the opening of the connecting pipe 106, so that the settled water can enter the water tank 2 through the connecting pipe 106.

[0046] Two rotating shafts 1011 are each fixedly mounted with a first pulley 1016 at one end extending outside the cooling platform 1. When the first pulley 1016 rotates, it will drive the rotating shaft 1011 to rotate, which in turn will drive the baffle 1017 to rotate.

[0047] The outer surface of the cooling platform 1 is rotatably connected to two second pulleys 1013 on one side of the first pulley 1016. The outer surfaces of the two second pulleys 1013 and the two first pulleys 1016 are respectively fitted with two belts 1012. Through the transmission of the belts 1012, when the second pulleys 1013 rotate, they will drive the first pulleys 1016 to rotate.

[0048] A first gear 1014 is fixedly installed on one side of the outer surface of each of the two second pulleys 1013, and the two first gears 1014 mesh. A first motor 1015 is fixedly installed on the outer surface of the cooling platform 1 on one side of the first gear 1014. The first motor 1015 is powered by an external power source, and the output shaft of the first motor 1015 is fixedly connected to one of the first gears 1014. The first motor 1015 drives one of the first gears 1014 to rotate, so that the two first gears 1014 can rotate in opposite directions, which in turn causes the two rotating shafts 1011 and the two baffles 1017 to rotate in opposite directions.

[0049] Two support blocks 5 are fixedly installed on the outer top surface of the cooling platform 1. The outer top surfaces of the two support blocks 5 are arc-shaped so as to better fit the outer surface of the steel pipe. Moreover, the top surfaces of the two support blocks 5 are rotatably connected to movable rollers 501.

[0050] The working principle of this utility model is as follows: the steel pipe to be cooled is placed on the top surface of two support blocks 5, and then the sliders of the two electric slide rails 2011 drive the two support plates 2012 to move closer to the steel pipe until the two fixing blocks 2015 clamp and fix the steel pipe, so that the second spray head 207 is inserted into the inside of the steel pipe. Then the water pump 202 transmits the water in the water tank 2 to the first spray head 4 and the second spray head 207 to spray water to the outside and inside of the steel pipe to cool the steel pipe.

[0051] Water sprayed onto the steel pipe falls into the cooling platform 1, where three filter plates 101 filter it to remove impurities. The filtered water then falls into the cooling platform 1 to settle. Once the settled water reaches a certain height, the first motor 1015 drives one of the first gears 1014 to rotate, causing the two first gears 1014 to rotate in opposite directions. This, combined with the transmission of the belt 1012, causes the two rotating shafts 1011 to drive the two baffles 1017 to rotate until the two baffles 1017 rotate to a horizontal position. The settled water then enters the water tank 2 through the connecting pipe 106 for reuse.

[0052] When the micro motor 1035 is powered on, it drives the second bevel gear 1034 to rotate, which in turn drives the first bevel gear 1033 and the connecting rod 1036 to rotate. The connecting rod 1036 then drives the reciprocating screw 1032 to rotate. The connecting plate 103, along with the rotation of the reciprocating screw 1032, drives the three movable rods 102 and the three brush plates 104 to reciprocate. The brush plates 104 then wipe and clean the filter plate 101.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
