Description

Technical Field

[0001] This utility model relates to the technical field of peeling devices, specifically a peeling device for the anti-corrosion layer of gas pipelines. Background Technology

[0002] A gas pipeline anti-corrosion coating stripping device is a specialized piece of equipment used to remove the outer anti-corrosion coating from gas pipelines. Because gas pipelines are buried underground for extended periods, they are subject to erosion by corrosive media in the soil. Therefore, the anti-corrosion coating stripping device plays a crucial role in the maintenance and management of gas pipelines. This device is primarily used to remove the anti-corrosion coating from the surface of gas pipelines to facilitate pipeline inspection, repair, or recoating. It helps maintenance personnel quickly and efficiently remove the pipeline anti-corrosion coating, improving work efficiency and the quality of pipeline maintenance. Anti-corrosion coating stripping devices typically employ either mechanical or chemical stripping methods. Mechanical stripping uses the friction between mechanical parts such as blades or brushes and the pipeline surface to peel off the anti-corrosion coating. Chemical stripping utilizes chemical solvents to react with the anti-corrosion coating, softening it and making it easier to peel off.

[0003] When using existing devices, there is a lack of professional tools on the market for peeling off the anti-corrosion coating of gas pipelines. This makes the peeling process rely on manual operation or simple mechanical tools, which is not only inefficient but also easy to damage the pipeline. Therefore, we need to propose a gas pipeline anti-corrosion coating peeling device. Utility Model Content

[0004] The purpose of this utility model is to provide a gas pipeline anti-corrosion layer peeling device. The mounting shell is used to install the cutting blade, and a knob is used to drive the first screw to rotate. The first screw and the internal threaded ring generate threaded movement, controlling the first screw to pass through the through hole on the cutting blade and enter the interior of the limiting hole, which limits the cutting blade and facilitates disassembly and replacement of the cutting blade. At the same time, the two ends of the mounting shell are provided with a first fixing rod and a second fixing rod, and the anti-slip sleeve and the movable sleeve facilitate the operator to apply force, making it easier for the cutting blade to peel off the anti-corrosion layer, thereby solving the problems mentioned in the background art.

The cutting blade 2 has two symmetrically distributed through holes 3 inside, and a first screw 4 is provided inside each of the two through holes 3. A knob 5 is fixedly connected to the upper end of the first screw 4. An internal threaded ring 6 is threadedly connected to the outer side of the first screw 4. Two symmetrically distributed limiting holes 7 are opened at the inner bottom of the mounting shell 1. The two limiting holes 7 are rotatably connected to the two first screws 4 respectively. A first fixing rod 8 is fixedly connected to the side wall of the mounting shell 1. An anti-slip sleeve 9 is fixedly connected to the outer side of the first fixing rod 8. A second fixing rod 10 is fixedly connected to the other side of the mounting shell 1. A movable sleeve 11 is slidably connected to the outer side of the second fixing rod 10.

[0022] The mounting housing 1 is used to install the cutting blade 2. At the same time, the knob 5 is used to drive the first screw 4 to rotate. The first screw 4 and the internal threaded ring 6 will have a threaded movement. The first screw 4 is controlled to pass through the through hole 3 on the cutting blade 2 and enter the interior of the limiting hole 7, which limits the cutting blade 2 and facilitates disassembly and replacement of the cutting blade 2. At the same time, the two ends of the mounting housing 1 are provided with a first fixing rod 8 and a second fixing rod 10. The anti-slip sleeve 9 and the movable sleeve 11 facilitate the operator to apply force and facilitate the cutting blade 2 to peel off the anti-corrosion layer. Multiple evenly distributed protrusions 12 are fixedly connected to the side wall of the movable sleeve 11, and the protrusions 12 serve as anti-slip.

[0023] The internal threaded ring 6 is fixedly connected to the mounting shell 1, and the internal threaded ring 6 is in contact with the knob 5.

[0024] For example, the mounting housing 1 serves to mount the internal threaded ring 6, and the internal threaded ring 6 limits the position of the knob 5.

[0025] The movable sleeve 11 is rotatably connected to a second screw 13. The second fixed rod 10 has a threaded groove 14 inside, which is threadedly connected to the second screw 13.

[0029] The working principle of this utility model is as follows: When in use, the mounting shell 1 is used to install the cutting blade 2, and the knob 5 is used to drive the first screw 4 to rotate. The first screw 4 and the internal thread ring 6 generate threaded movement, controlling the first screw 4 to pass through the through hole 3 on the cutting blade 2 and enter the interior of the limiting hole 7, which limits the cutting blade 2 and facilitates disassembly, making it easy to replace the cutting blade 2.

[0030] Rotating handle 17 causes rotating disk 16 to rotate, which in turn causes second screw 13 to rotate. The second screw 13 and threaded groove 14 move together. The second screw 13 causes movable sleeve 11 to slide outside the second fixed rod 10, which facilitates adjusting the distance between movable sleeve 11 and anti-slip sleeve 9. When movable sleeve 11 slides, guide rod 18 slides inside slide groove 19, which guides movable sleeve 11. Fixed ring 15 installs and limits the second screw 13.
