Description
Technical Field
[0001] The utility model relates to the technical field of pipeline steel impurity removal, in particular to an impurity removal device for pipeline steel production in a steelmaking plant. Background Art
[0002] During the steelmaking process, the purity of pipeline steel directly affects the quality of the final product. Traditional impurity removal for pipeline steel generally involves cleaning the outer wall of the pipeline steel. When cleaning the inner wall of pipeline steel with a larger inner diameter, handheld tools are often used to clean the inner wall of pipeline steel with a smaller inner diameter. When cleaning the inner wall of pipeline steel with a smaller inner diameter, a cleaning brush is often moved back and forth inside the pipeline steel to remove impurities. This impurity removal method is not only inefficient and relatively cumbersome to operate, but also difficult to ensure the effectiveness of the inner wall impurity removal. In addition, the waste chips removed need to be cleaned separately, resulting in significant limitations in the impurity removal operation.
[0003] Therefore, the utility model proposes a steelmaking plant pipeline steel production impurity removal device to solve the above problems.

[0028] Reference Figure 1-4 The cam 32 is fixedly mounted on the front and rear inner walls of the housing 1, and a wide gear 33 is fixedly sleeved on the cam 32. A plurality of tooth plates 31 are slidably mounted on the housing 1 and the inner ring 2. The plurality of tooth plates 31 are meshed with the wide gear 33. The plurality of tooth plates 31 extend outside the housing 1 and are fixedly connected to the corresponding mounting seats 3 respectively, which can provide support for the mounting seats 3 and can adjust the distance between the mounting seats 3 and the housing 1 when the wide gear 33 rotates, so that the device can better adapt to the inner wall impurity removal operation of pipeline steels with different inner diameters. The same rotating rod 34 is rotatably mounted on the front and rear inner walls of the housing 1, and an electric cylinder 35 is radially fixedly mounted on the rotating rod 34. A rotating pin is radially fixedly mounted on the working end of the electric cylinder 35. The pin is rotatably mounted on the front side of the wide gear 33, and can control the wide gear 33 to deflect based on the rotating shaft 32 as needed. A mounting bracket 5 is fixedly mounted on the side of the mounting seat 3 away from the shell 1, and two support shafts 51 arranged parallel to each other are rotatably mounted on the mounting bracket 5. Guide wheels 52 are fixedly sleeved on the two support shafts 51, and a servo motor 53 is fixedly mounted on the mounting bracket 5. The output shaft of the servo motor 53 is axially fixedly connected to one of the support shafts 51, which can control the device to maintain contact with the inner wall of the pipeline steel, and at the same time facilitate the control of the shell 1 to rotate based on the axis of the pipeline steel. A grinding motor 4 is fixedly mounted on the side of the mounting seat 3 away from the shell 1, and a grinding wheel 41 is fixedly mounted on the output shaft of the grinding motor 4. The connecting cylinder 6 is fixedly mounted on the front side of the shell 1, and a plurality of through-holes 12 and a plurality of feed ports 11 are respectively opened on the front side and the outer peripheral side of the shell 1, and the connecting cylinder 6 is connected to the shell 1 through the plurality of through-holes 12, and the connecting pipe 61 is rotatably mounted on the front side of the connecting cylinder 6.
[0029] In this embodiment, in order to ensure the stability of the housing 1 when moving in the pipeline steel, there are two guide wheels 52 located on the same support shaft 51.
[0030] In this embodiment, in order to ensure that the device can be controlled to maintain a moving state inside the pipeline steel when the guide wheel 52 moves along the inner wall of the pipeline steel, the angle between the axis of the rotating shaft 32 and the axis of the shell 1 is 5-15 degrees, and the specific angle is determined according to the width that can be covered by the grinding wheel 41 during grinding.
[0031] In this embodiment, in order to enable the mounting base 3 to be better attached to the outer side of the shell 1 when the device is stored after use, thereby reducing the space occupied in the idle state, the side of the mounting base 3 close to the shell 1 is set to be an arc surface.
[0032] In this embodiment, in order to adapt to both straight pipeline steel and pipeline steel with a certain degree of curvature, the connecting pipe 61 is semi-rigid.
[0033] In this embodiment, in order to effectively increase the friction between the guide wheel 52 and the inner wall of the pipeline steel, thereby ensuring stable movement of the device when removing impurities from the inner wall of the pipeline steel, the outer peripheral surface of the guide wheel 52 is provided with rubber.
[0034] In this embodiment, in order to ensure that the debris in the shell 1 is more efficiently drawn out through the connecting cylinder 6 and the connecting tube 61 under the action of the suction force of the external dust suction device, and to avoid the accumulation of debris in the shell 1, the through-opening 12 is arranged in a circular shape, and the inner wall of the through-opening 12 is flush with the inner wall of the shell 1 away from the axis of the shell 1.
[0035] The grinding motor 4 and servo motor 53 involved and the required circuits all adopt existing technologies, which can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software, circuits and methods.
[0036] Working principle: When in use, first turn on the power and connect the connecting pipe 61 to the external dust collection device, place the device in the pipeline steel that needs to be cleaned, and control the wide gear 33 to deflect based on the rotating shaft 32 through the electric cylinder 35. Under the cooperation of the wide gear 33 and the tooth plate 31, adjust the distance between the mounting seat 3 and the shell 1 so that the multiple guide wheels 52 are in contact with the inner wall of the pipeline steel. Then start the servo motor 53, the grinding motor 4 and the external dust collection device. The grinding motor 4 controls the grinding wheel 41 to remove impurities from the inner wall of the pipeline steel. The servo motor 53 is turned on. The device is controlled by the support shaft 51 and the guide wheel 52 to advance slowly along the inner wall of the pipeline steel, thereby realizing continuous and efficient impurity removal operations. During the impurity removal process, the air on the outer peripheral side of the shell 1 can be extracted through the connecting pipe 61, the connecting cylinder 6, the through-port 12 and multiple feed ports 11 under the action of the external dust suction device, so that the cleaned debris is sucked into the position between the shell 1 and the inner ring 2 through the feed port 11, and then is extracted after passing through the through-port 12, the connecting cylinder 6 and the connecting pipe 61, so that the cleaned debris can be cleaned quickly and efficiently.
[0037] When the cleaning operation is completed, the power supply can be disconnected to stop the grinding motor 4 and the servo motor 53. At this time, the wide gear 33 can be controlled by the electric cylinder 35 to return to the initial position. At the same time, the mounting base 3 can be stored outside the housing 1 to reduce space occupation and facilitate transportation and storage of the device.
[0038] The design of the entire impurity removal device fully considers ease of operation, efficiency and quality, adaptability, and operational safety, making impurity removal in pipeline steel production more efficient and safe. Through its rational structural design, the device is not only suitable for straight pipeline steel, but also well adapted to pipeline steel with certain curvatures, greatly improving the scope of application and effectiveness of impurity removal operations.
[0039] The above is a detailed introduction to the impurity removal device for steel pipeline production in a steelmaking plant provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be pointed out that for ordinary technicians in this technical field, various improvements and modifications can be made to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
