[0002] A gas pipeline refers to a pipeline system for transporting gases such as natural gas and liquefied petroleum gas. It is an important passage connecting towns or cities with gas production or storage locations, used to transport gas to residential, industrial, and commercial users. To prevent corrosion, a layer of paint is usually applied to the outer periphery of the gas pipeline. To enhance the adhesion effect of the paint on the outer periphery of the gas pipeline, or to scrape off the old paint on the outer periphery of the gas pipeline and then apply a new coat of paint, a gas pipeline cleaning tool is required. Existing gas pipeline cleaning tools can only clean the gas pipeline from one side of the gas pipeline, and it is necessary to clean the gas pipeline from different sides of the gas pipeline multiple times, and it is impossible to complete the cleaning of the gas pipeline at one time. Therefore, we have designed a gas pipeline cleaning tool. Content of the Utility Model

Detailed implementation manners

[0015] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] A gas pipeline cleaning tool, such as Figure 1 、 2As shown in the figure, it includes two C-shaped plates 1. The two C-shaped plates 1 are symmetrically distributed left and right, and the opening directions of the two C-shaped plates 1 face each other. Cleaning devices for cleaning the gas pipeline 100 are respectively provided on the C-shaped plates 1. The two C-shaped plates 1 are installed on the same first cross plate 2, and the two C-shaped plates 1 are located on both sides of the gas pipeline 100. It is characterized in that: one end of the first connecting rod 3 is respectively fixedly connected to the bottom of the C-shaped plate 1, and the other end of the first connecting rod 3 is respectively rotatably connected to the first cross plate 2 through a hinge shaft. A lead screw 4 is fixedly installed on the first cross plate 2, and an internally threaded tube 5 is installed in threaded cooperation with the outer circumference of the lead screw 4. The lead screw 4 and the internally threaded tube 5 are coaxially arranged. The upper end of the internally threaded tube 5 is rotatably installed on the second cross plate 6 through a bearing. A first through hole 7 is provided on the second cross plate 6 corresponding to the lead screw 4. There is a gap between the inner circumference of the first through hole 7 and the outer circumference of the lead screw 4. One end of the second connecting rod 8 is respectively rotatably connected to both sides of the second cross plate 6 through a hinge shaft, and the other end of the second connecting rod 8 is successively rotatably connected to the bottom of the C-shaped plate 1 through a hinge shaft. The structure of the utility model is simple and ingenious. The distance between the left and right cleaning devices can be adjusted, which can be applied to the cleaning of gas pipelines 100 with various diameters, can meet the market demand, and is suitable for popularization. When using the utility model, rotate the internally threaded tube 5 clockwise, the internally threaded tube 5 moves downward, the downward movement of the internally threaded tube 5 drives the second cross plate 6 to move downward, and the downward movement of the second cross plate 6 drives the two C-shaped plates 1 and the first connecting rod 3 to rotate outward along the hinge shaft with the first cross plate 2 through the second connecting rod 8. The second connecting rod 8 rotates around the corresponding hinge shaft. Then hold the lead screw 4 by hand to make the two C-shaped plates 1 located on both sides of the gas pipeline 11. Then rotate the internally threaded tube 5 counterclockwise to make the internally threaded tube 5 move upward. Similarly, the upward movement of the internally threaded tube 5 makes the two C-shaped plates 1 and the first connecting rod 3 rotate inward along the corresponding hinge axes until the cleaning device contacts the outer circumference of the gas pipeline 100, and the outer circumference of the gas pipeline 100 is cleaned and polished by the cleaning device.

[0017] Specifically, as shown in the figure, the cleaning device in this embodiment includes a synchronous pulley 20. Two synchronous pulleys 20 are respectively rotatably installed at the opening of the C-shaped plate 1, and one synchronous pulley 20 is respectively rotatably installed on one side of the C-shaped plate 1 far away from the opening. The three synchronous pulleys 20 on one C-shaped plate 1 are distributed in an isosceles triangle. A synchronous belt 21 is cooperatively provided on the outer periphery of the three synchronous pulleys 20 on the same C-shaped plate 1. The outer periphery of the synchronous belt 21 is respectively fixedly installed with a sand belt 22. The synchronous pulley 20 away from the opening of the C-shaped plate 1 is rotatably installed on the movable end of the spring rod 23 through the first L-shaped rod 24. The outer periphery of one end of the L-shaped rod 24 is rotatably connected to the inner periphery of the corresponding synchronous pulley 20 through a bearing. The other end of the L-shaped rod 24 is fixedly installed on the movable end of the spring rod 23. The fixed end of the spring rod 23 is fixedly installed on the corresponding C-shaped plate 1. Second through holes 25 are respectively opened on the C-shaped plate 1 corresponding to the spring rod 23. The fixed end of the spring rod 23 is fixedly installed in the corresponding second through hole 25. A driving device for driving the synchronous pulley 20 to rotate is respectively provided on the C-shaped plate 1. By driving the corresponding synchronous pulley 20 to rotate through the driving device, the synchronous pulley 20 drives the other two synchronous pulleys 20 to rotate through the synchronous belt 21. While the synchronous belt 21 rotates, it drives the sand belt 22 to rotate. The rotation of the sand belt 22 cleans the outer periphery of the gas pipeline 100. When the two sand belts 22 wrap around the outer periphery of the gas pipeline 100, the movable end of the spring rod 23 can be stretched, driving the corresponding grinding wheel synchronous pulley 20 to move towards each other. Since the length of the sand belt 22 remains unchanged, the length of the sand belt 22 between the two synchronous pulleys 20 at the opening becomes longer at this time, so that the sand belt 22 can be fitted and cooperated with the outer periphery of the gas pipeline 100, so as to increase the contact area between the sand belt 22 and the outer periphery of the gas pipeline 100.

[0018] Specifically, as shown in the figure, the driving device in this embodiment includes two motors 30. The motors 30 correspond to the C-shaped plates 1 one by one. The two motors 30 are sequentially fixedly installed on the corresponding C-shaped plates 1 through the second L-shaped rods 31. The output shaft of the motor 30 is coaxially and fixedly connected to a synchronous pulley 20 at the opening end of the corresponding C-shaped plate 1. Starting the motor 30, the output shaft of the motor 30 rotates to drive the corresponding synchronous pulley 20 to rotate, and then drives the other two synchronous pulleys 20 to rotate through the synchronous belt 21.

[0019] Further, as shown in the figure, one end of a wire 40 is electrically connected to the corresponding motor 30 in this embodiment. Third through holes 41 and through slots 42 are sequentially opened on the first cross plate 2 and the lead screw 4 corresponding to the wire 40. The two wires 40 pass through the third through holes 41 and the through slots 42, and then extend out from the lower end of the lead screw 4 and are electrically connected to the power supply. Passing the wire 40 through the third through hole 41 and the through slot 42 and extending out from the lower end of the lead screw 4 can prevent the wire 40 from being wound around other components.

[0020] Furthermore, as shown in the figure, the two C-shaped plates 1 in this embodiment are staggered in the front and rear directions. The staggered distribution of the two C-shaped plates 1 in the front and rear directions can prevent interference between the two C-shaped plates 1 and the components on the C-shaped plates 1 when the abrasive belt 22 wraps around the outer periphery of the gas pipeline 100.

[0021] Still further, as shown in the figure, stop bars 60 are respectively and fixedly installed at the diagonals of the first horizontal plate 2 in this embodiment, and the hinge axis of the first connecting rod 3 and the first horizontal plate 2 is located at the other two diagonals of the first horizontal plate 2. Through the two stop bars 60, it is possible to prevent the gas pipeline 100 from tilting under the thrust of the abrasive belt 22 when the abrasive belt 22 is pressed against the gas pipeline 100 for alignment and grinding, and the stop bars 60 can come into contact and cooperate with the gas pipeline 100.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
