Description

Technical Field

[0001] This utility model relates to the field of pipeline descaling technology, specifically to a descaling system. Background Technology

[0002] The purpose of descaling is to remove iron oxide scale to prevent it from pressing into the surface and causing defects, thereby improving the surface quality of the product. Methods include: bamboo branches, apricot twigs, salt, or roller presses, wire brushes, compressed air, steam purging, descaling machines, and high-pressure water, etc. High-pressure water descaling boxes and high-pressure water nozzles before and after the rolling mill are most suitable, with water pressure increased from 12MPa to 15-25MPa or higher, and even higher for alloy steel. In the pipeline production process of steel mills, the iron oxide scale generated after pipeline heating needs to be removed by high-pressure water jetting. Strict requirements are placed on the jetting distance. In actual production lines, various specifications of steel pipes are involved, corresponding to several descaling manifolds. When changing to other specifications of steel pipes, the descaling manifold also needs to be replaced.

[0003] Patent CN114453444A discloses a quick-change descaling manifold device, comprising a base, a housing fixedly mounted on the base, a conveying assembly mounted on the base and located within the housing, and a descaling mechanism mounted on the housing. The housing has an inlet and an outlet. The descaling mechanism includes a switching mechanism and four descaling components mounted on the switching mechanism. Each descaling component includes a mounting shell, an annular guide tube within the mounting shell, and high-pressure nozzles evenly arranged on the annular guide tube. The mounting shell has a channel hole for the pipe to pass through, and the high-pressure nozzles all face the center of the annular guide tube. A connecting pipe is provided on the mounting shell, with one end connected to the annular guide tube and the other end connected to the switching mechanism. The mounting shells within the descaling components are connected together by connectors. In practical use, this device allows for descaling of pipes of different specifications without disassembling the manifold, making it more convenient to use.

[0004] In practical applications, since the pipes requiring descaling have different diameters, a conveying assembly is needed to support and transport the pipes. In existing technologies, when conveying pipes of different diameters, the axial position of the pipes cannot be kept in the same position as the pipe diameter changes. This means that when switching to different descaling assemblies to descale the pipes, the pipes are not in the center of the descaling assembly, resulting in inconsistent distances between the pipe surface and the spray nozzles in the descaling assembly, which affects the descaling effect on the pipe surface. Utility Model Content

[0005] The purpose of this invention is to provide a descaling system that can effectively solve the technical problem in the prior art where the axial position of the pipe cannot be kept in the same position as the pipe diameter changes. This results in the pipe not being in the center of the descaling component when switching to different descaling components, leading to inconsistent distances between the pipe surface and the spray head in the descaling component, thus affecting the descaling effect on the pipe surface.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A descaling system includes a base, a conveying assembly mounted on the base for carrying a pipeline, the conveying assembly including a bearing housing, a carrying unit rotatably mounted on the bearing housing, and a drive mechanism mounted on the bearing housing for driving the carrying unit to rotate.

[0008] The bearing unit includes a bearing shaft, a first support part and a second support part slidably disposed on the bearing shaft, and a bearing surface for contacting the pipe is provided on both the first support part and the second support part. A V-shaped bearing area is formed between the bearing surfaces on the first support part and the second support part.

[0009] The first support and the second support are connected by an adjustment mechanism, which is used to adjust the distance between the first support and the second support.

[0010] Furthermore, a guide portion is provided on the bearing shaft, and a sliding groove is provided on the first support portion and the second support portion. The first support portion and the second support portion are slidably mounted on the bearing shaft through the sliding groove and the guide portion, so that the first support portion and the second support portion can move in the radial direction of the bearing shaft.

[0011] Furthermore, a limiting part is provided at the middle position of the bearing shaft, and the adjustment mechanism is installed on the limiting part and then connected to the first support part and the second support part.

[0012] Furthermore, the adjustment mechanism includes an adjustment shaft with oppositely rotating threads. Both the first support and the second support are provided with threaded holes that are threadedly engaged with the adjustment shaft. The adjustment shaft is rotatably mounted on the limiting part.

[0013] Furthermore, the adjusting shaft is rotatably mounted on the limiting part via a bearing.

[0014] Furthermore, the adjustment shaft extends into a first support portion and a second support portion, and a protruding polygonal structure is provided at one end of the adjustment shaft.

[0015] Furthermore, the drive mechanism is a drive motor.

[0016] Furthermore, wear-resistant pads are provided on the bearing surface.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model is mainly used to support and transport pipes to be descaled. During use, the position of the contact point between the pipe to be descaled and the bearing surface can be adjusted by adjusting the positions of the first and second support parts. In existing technologies, multiple descaling components are used to descale pipes of different diameters. When the pipe diameter is different, the pipe axis changes when the pipe is placed on the bearing unit, resulting in varying distances between the inner wall of the pipe and the spray nozzle in the descaling component. In this application, the distance between the first and second support parts is adjusted by an adjustment mechanism, ensuring that the axes of different pipes are all in the same position. This allows the pipe to pass through the center of the descaling component, ensuring that the distance from the outer wall of the pipe to the spray nozzle in the descaling component is the same, thereby guaranteeing the descaling effect.

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] See Figures 1-4 This embodiment discloses a descaling system, including a base 101, a conveying assembly 103 disposed on the base 101 for carrying a pipe 102, the conveying assembly 103 including a bearing seat 104, a carrying unit 105 rotatably mounted on the bearing seat 104, and a driving mechanism 106 mounted on the bearing seat 104 for driving the carrying unit 105 to rotate.

[0035] In actual use, the base 101 is equipped with a box 107 and a descaling component 108;

[0036] The bearing unit 105 includes a bearing shaft 109, a first support portion 110 and a second support portion 111 slidably disposed on the bearing shaft 109, and a bearing surface 112 for contacting the pipe 102 is provided on both the first support portion 110 and the second support portion 111. A V-shaped bearing area 113 is formed between the bearing surfaces 112 on the first support portion 110 and the second support portion 111.

[0037] The first support part 110 and the second support part 111 are connected by an adjustment mechanism 114, which is used to adjust the distance between the first support part 110 and the second support part 111.

[0038] This utility model is mainly used to support and transport the pipe 102 to be descaled. During use, the position of the contact point between the pipe 102 and the bearing surface 112 can be adjusted by adjusting the positions of the first support part 110 and the second support part 111. In the prior art, multiple descaling components are used to descale pipes 102 of different diameters. When the pipe diameter is different, the axis of the pipe 102 changes when placed on the bearing unit 105, resulting in varying distances between the inner wall of the pipe 102 and the spray nozzle in the descaling component 108. In this application, the distance between the first support part 110 and the second support part 111 is adjusted by the adjustment mechanism 114, ensuring that the axes of different pipes 102 are all in the same position. This allows the pipe 102 to pass through the center of the descaling component 108, ensuring that the distance from the outer wall of the pipe 102 to the spray nozzle in the descaling component is the same, thereby guaranteeing the descaling effect.

[0039] Furthermore, in practical use, the bearing shaft 109 is provided with a guide portion, and the first support portion 110 and the second support portion 111 are provided with sliding grooves. The first support portion 110 and the second support portion 111 are slidably mounted on the bearing shaft 109 through the sliding grooves and the guide portion, so that the first support portion 110 and the second support portion 111 can move in the radial direction along the bearing shaft 109. This arrangement allows the first support portion 110 and the second support portion 111 to rotate with the bearing shaft 109 under the action of the sliding grooves and the guide portion when the bearing shaft 109 rotates.

[0040] Furthermore, in some preferred embodiments, the bearing axis 109 can be configured as a polygonal axis.

[0041] The bearing shaft 109 has a limiting part 115 at the middle position, and the adjusting mechanism 114 is installed on the limiting part 115 and then connected to the first support part 110 and the second support part 111.

[0042] Furthermore, the adjustment mechanism 114 includes an adjustment shaft 116, on which threads with opposite directions of rotation are provided. The first support portion 110 and the second support portion 111 are both provided with threaded holes 117 and are threadedly engaged with the adjustment shaft 116. The adjustment shaft 116 is rotatably mounted on the limiting portion 115.

[0043] The adjusting shaft 116 is rotatably mounted on the limiting part 115 via the bearing 118.

[0044] In practical use, by rotating the adjusting shaft 116, the first support part 110 and the second support part 111 can move closer to each other or further away from each other under the action of the threads with opposite directions, so as to adjust the position of the first support part 110 and the second support part 111, and adjust the contact point between the pipe 102 and the bearing surface 112 on the first support part 110 and the second support part 111, so as to ensure that the axis of the pipe 102 is basically in the same position.

[0045] Furthermore, the adjusting shaft 116 extends to form a first support portion 110 and a second support portion 111, and a protruding polygonal structure 119 is provided at one end of the adjusting shaft 116. In actual use, the adjusting shaft 116 can be rotated by using a tool in conjunction with the polygonal structure 119.

[0046] Furthermore, in actual use, an adjustment handwheel can be installed at the end of the adjustment shaft 116.

[0047] In the futures market, the drive mechanism 106 is a drive motor.

[0048] Furthermore, wear-resistant pads are provided on the bearing surface 112. The wear-resistant pads provide protection.

[0049] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
