Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting and rust removal of steel pipes, and in particular to a sandblasting and rust removal device for coated composite steel pipes. Background Technology

[0002] Plastic-coated composite steel pipe, also known simply as plastic-coated steel pipe, is a special type of steel-plastic composite product. It uses a steel pipe as the base material and plastic powder as the coating material. A layer of plastic is evenly applied to the inner surface of the steel pipe through a melting process, while a plastic layer or other anti-corrosion material layer is coated on the outer surface. Currently, steel pipes are often treated using sandblasting for rust removal. This involves using compressed air to drive quartz sand or corundum at high speed to blast the workpiece surface, effectively removing rust through the impact force of the sand particles.

[0003] In traditional steel pipe sandblasting rust removal operations, operators must hold the spray gun and move it constantly to ensure that the sand fully covers the surface of the steel pipe. However, this method is not only inefficient, but also difficult to control precisely by hand, easily leading to repeated sandblasting and wasting resources. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a sandblasting and rust removal device for coated composite steel pipes. The device uses a limiting component to position the sandblasting seat and, in conjunction with a control mechanism, can precisely control the sandblasting seat to move smoothly along the limiting rail, thereby achieving uniform sandblasting treatment on the area of ​​the steel pipe covered by the limiting component. This design not only significantly reduces the labor intensity of manual sandblasting but also effectively avoids repeated sandblasting, ensuring the uniformity of the sandblasting effect and a significant improvement in work efficiency.

[0006] To achieve the above objectives, this utility model proposes a sandblasting and rust removal device for coated composite steel pipes, comprising a limiting component, a movement control mechanism, and a sandblasting base. The limiting component has an arc-shaped curved surface, and its bottom surface is provided with a serpentine limiting rail. The movement control mechanism includes a lateral moving component and a longitudinal moving component. The lateral moving component is arc-shaped and matches the shape of the limiting component. The lateral moving component is laterally movable at the bottom of the limiting component via a first driving component, and a first sliding groove is formed on one side of the lateral moving component. The longitudinal moving component is linear and perpendicular to the lateral moving component. The longitudinal moving component is longitudinally movable at the bottom of the limiting component via a second driving component, and a second sliding groove is formed on one side of the longitudinal moving component. One side of the sandblasting base has a limiting part for mounting a spray gun, and the other side of the sandblasting base has a slider with three branches. The three branches are respectively slidably disposed within the limiting rail, the first sliding groove, and the second sliding groove.

[0007] This utility model discloses a sandblasting and rust removal device for coated composite steel pipes. First, personnel use a limiting component to position the sandblasting base, specifically covering one side of the steel pipe. Simultaneously, the spray gun is securely installed on the sandblasting base. Then, personnel precisely control the sandblasting base to move smoothly along the limiting rail using a control mechanism, thereby achieving uniform sandblasting treatment on the area of ​​the steel pipe covered by the limiting component. This design not only significantly reduces the labor intensity of manual sandblasting but also effectively avoids repeated sandblasting, ensuring uniform sandblasting results and a significant improvement in work efficiency.

[0008] In addition, the sandblasting and rust removal device for coated composite steel pipes proposed in the application may also have the following additional technical features:

[0009] Specifically, the longitudinal moving member is slidably disposed between the limiting member and the lateral moving member.

[0010] Specifically, a limiting frame is provided on one side of the limiting member, the second driving member is disposed within the limiting frame, and the second driving member includes a moving block, a connecting rope, and two winding wheels. The moving block is slidably disposed within the limiting frame, and its bottom is connected to the longitudinal moving member.

The two ends of the connecting rope are respectively disposed on the two winding wheels, and the connecting rope is fixedly disposed through the moving block.

[0011] Specifically, the other side of the limiting member is provided with a side plate, and the first driving member is provided on the side plate.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following description, in conjunction with the accompanying drawings, describes the sandblasting and rust removal device for coated composite steel pipes according to an embodiment of the present invention.

[0021] like Figures 1-4 As shown, the sandblasting and rust removal device for coated composite steel pipes in this embodiment of the present invention may include a limiting member 10, a movement control mechanism 20, and a sandblasting base 30.

[0022] The limiting member 10 has an arc-shaped curved surface, and the bottom surface of the limiting member 10 is provided with a serpentine limiting rail 101.

[0023] The motion control mechanism 20 may include a lateral moving member 201 and a longitudinal moving member 202. The lateral moving member 201 is shaped to match the limiting member 10, both being arc-shaped. The lateral moving member 201 is laterally movable at the bottom of the limiting member 10 via a first driving member 40. A first sliding groove 2011 is formed on one side of the lateral moving member 201. A side plate 12 is provided on the other side of the limiting member 10, and the first driving member 40 is disposed on the side plate 12. The longitudinal moving member 202 is linearly arranged and perpendicular to the lateral moving member 201. The longitudinal moving member 202 is longitudinally movable at the bottom of the limiting member 10 via a second driving member 50. A second sliding groove 2021 is formed on one side of the longitudinal moving member 202. The longitudinal moving member 202 slidably lies between the limiting member 10 and the lateral moving member 201. A limiting frame 11 is provided on one side of the limiting member 10. The second driving member 50 is located inside the limiting frame 11. The second driving member 50 may include a moving block 501, a connecting rope 502, and two winding wheels 503. The moving block 501 is slidably located inside the limiting frame 11, and its bottom is connected to the longitudinal moving member 202. The two winding wheels 503 are respectively located at both ends of the limiting frame 11, and a drive motor 5031 is connected to each winding wheel 503. The two ends of the connecting rope 502 are respectively located on the two winding wheels 503, and the connecting rope 502 is fixedly installed through the moving block 501.

[0024] It should be noted that the first driving component 40 described in this embodiment has the function of controlling the lateral moving component 201 to move laterally, and it can be a cylinder, telescopic motor, etc.

[0025] It should be noted that by controlling the two take-up wheels 503 to rotate synchronously in opposite directions, the moving block 501 can be driven to move within the limit frame 11 via the connecting rope 502, thereby smoothly driving the longitudinal limit member 10 to move longitudinally on the bottom surface of the limit member 10.

[0026] One side of the sandblasting base 30 is provided with a limiting part 301 (which may be a clamp, etc.) for mounting the spray gun 70, and the other side of the sandblasting base 30 is provided with a slider 302. The slider 302 is provided with three branches 3021, wherein the three branches 3021 are respectively slidably disposed in the limiting rail 101, the first slide groove 2011 and the second slide groove 2021. The slider 302 described in this embodiment is pushed by the transverse moving member 201 and / or the longitudinal moving member 202, and can move accordingly on the limiting rail 101. During the process, the slider 302 can slide accordingly in the first slide groove 2011 and / or the second slide groove 2021.

[0027] It should be noted that the limiting part 301 described in this embodiment can be a clamp. The limiting part 301 can limit the installation of the spray gun 70 of the external sandblasting equipment, so that the sandblasting base 30 can drive the spray gun 70 to move.

[0028] As a possible scenario, when fixing the position of the limiting member 10, relevant personnel may use an external fixing mechanism (such as a support frame) to help the limiting member 10 maintain its position.

[0029] Specifically, in the actual operation, the relevant personnel first use the limiting component 10 to position the sandblasting base 30. Specifically, the limiting component 10 is covered on one side of the steel pipe 60, and the spray gun 70 is firmly installed on the sandblasting base 30 and the spray gun 70 is aligned with the steel pipe 60. At this time, the sandblasting base 30 is located at one end of the limiting rail 101.

[0030] Subsequently, based on the direction of the limiting rail 101, the lateral moving part 201 / longitudinal moving part 202 are selectively manipulated to push the slider 302 to move to the other end of the limiting rail 101. During this process, the sandblasting seat 30 and the spray gun 70 can move smoothly along the limiting rail 101, thereby achieving uniform sandblasting treatment on the area of ​​the steel pipe 60 covered by the limiting part 10. This design not only greatly reduces the labor intensity of manual sandblasting, but also effectively avoids repeated sandblasting, ensuring the uniformity of the sandblasting effect and a significant improvement in work efficiency.

[0031] In summary, the sandblasting and rust removal device for coated composite steel pipes of this utility model uses limiting components to position the sandblasting station, and in conjunction with the control mechanism, it can precisely control the sandblasting station to move smoothly along the limiting rail, thereby achieving uniform sandblasting treatment on the area of ​​the steel pipe covered by the limiting components. This design not only greatly reduces the labor intensity of manual sandblasting, but also effectively avoids repeated sandblasting, ensuring the uniformity of the sandblasting effect and a significant improvement in work efficiency.
