Description

Technical Field

[0001] The utility model relates to the technical field of chemical pipeline removal, in particular to a chemical pipeline removal fracture plugging mechanism. Background Art

[0002] Chemical pipelines refer to pipelines for transporting chemical raw materials, which are mainly made of steel or alloys. They have good wear resistance and corrosion resistance. However, due to their certain firmness, chemical pipelines are difficult to dismantle when chemical buildings are demolished. As a result, when dismantling chemical buildings, chemical pipelines need to be blocked to prevent chemicals from being scattered in the air. However, the existing chemical pipeline dismantling fracture blocking mechanism has some shortcomings when used;

[0003] In order to ensure the sealing performance and to better enable the chemical pipeline dismantling fracture plugging mechanism to plug chemical pipelines of different diameters, the existing chemical pipeline dismantling fracture plugging mechanism is basically customized, which leads to the lack of versatility of the existing chemical pipeline dismantling fracture plugging mechanism and the high cost of customization, which increases the cost of use. In addition, the existing chemical pipeline dismantling fracture plugging mechanism has a single function and can only play a plugging role. In this way, when the chemical pipeline is dismantled, a large amount of toxic chemicals will be directly dispersed in the air, thereby polluting the environment. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a chemical pipeline dismantling fracture sealing mechanism to more accurately solve the problem that chemical pipelines of different diameters cannot be universally used and the functional structure is single.

[0005] The utility model is realized by the following technical solutions:

[0006] The utility model proposes a chemical pipeline dismantling fracture sealing mechanism, comprising a sleeve tube, an automatic telescopic rod is fixedly arranged on the inner wall of the sleeve tube, a telescopic ring is fixedly arranged on the output end of the automatic telescopic rod, a sliding block is slidably arranged on the surface of the sleeve tube, a moving cylinder is fixedly arranged on the surface of the sliding block, a plug-in rod is movably inserted into the top end of the moving cylinder, a cover plate is threadedly connected to the front face of the sleeve tube, an adsorption carbon layer is fixedly arranged inside the moving cylinder, and a sponge layer is fixedly arranged on the inner wall of the moving cylinder.

[0007] Furthermore, four sets of grooves are fixedly provided at the top and bottom ends of the sleeve tube, and the grooves are adapted to the plug-in rod, ensuring that the plug-in rod can be movably plugged into the grooves at the top and bottom ends of the sleeve tube, thereby utilizing the clamping connection between the plug-in rod and the groove to fix the moving position of the movable tube.

[0008] Furthermore, both sides of the sleeve tube are fixedly provided with slide grooves, and the slide grooves and the sliding blocks are adapted to ensure that the sliding blocks can slide inside the slide grooves, thereby utilizing the movement of the sliding blocks to assist and limit the movement trajectory of the moving tube.

[0009] Furthermore, sixteen groups of balls are movably arranged on the inner wall of the telescopic ring, and the balls are fixedly connected to the telescopic ring by springs. The elasticity of the springs is used to drive the balls to move and reset, and the rolling of the balls can facilitate the movement of the telescopic ring on the surface of the chemical pipeline, making it convenient for the telescopic ring to be sleeved on the surface of the chemical pipeline.

[0010] Furthermore, there are two groups of the plug-in rods, which are respectively located at the top and bottom ends of the moving cylinder. The plug-in rods and the moving cylinder are fixedly connected by springs, and the elasticity of the springs is used to facilitate the movement and resetting of the plug-in rods, and also to avoid the loss of the plug-in rods.

[0011] Furthermore, the cross-sectional diameter of the moving cylinder is larger than the cross-sectional diameter of the sleeve cylinder, thereby ensuring that the movement of the moving cylinder can drive the sponge layer to seal the telescopic ring inside the sleeve cylinder.

[0012] Furthermore, a handle is fixedly provided on the front side of the cover plate, so that the user can rotate the cover plate through the handle to realize the removal of the cover plate.

[0013] Furthermore, the sponge layer is located on the back of the adsorption carbon layer, and both the adsorption carbon layer and the sponge layer are compatible with the moving cylinder, ensuring that the sponge layer can be used to seal the telescopic ring and the activated carbon layer can be used to adsorb toxic chemicals.

[0014] Beneficial effects of the utility model:

[0015] The utility model drives the telescopic ring to automatically telescope by an automatic telescopic rod, so that the telescopic ring can be sleeved on chemical pipelines of different diameters, and the outlet of the telescopic ring is sealed by the movement of the sponge layer and the moving cylinder to ensure the sealing tightness, thereby finally making the device universal.

[0016] The utility model can adsorb toxic chemicals through the activated carbon layer, and can ensure the disassembly of the cover plate through rotation, and then the sponge layer and the adsorption carbon layer can be disassembled and replaced, thereby reducing the dispersion of toxic chemicals and protecting the atmospheric environment. The overall structure is simple, the operation is easy, and the utility model has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] As an implementation method in this embodiment, Figure 2 and Figure 3As shown, four groups of grooves are fixedly provided at the top and bottom ends of the sleeve tube 1, and the grooves are matched with the plug-in rod 6 to ensure that the plug-in rod 6 can be movably plugged into the grooves at the top and bottom ends of the sleeve tube 1, so that the clamping connection between the plug-in rod 6 and the grooves is used to fix the moving position of the moving tube 5; sliding grooves are fixedly provided on both sides of the sleeve tube 1, and the sliding grooves are matched with the sliding block 4 to ensure that the sliding block 4 can slide inside the sliding grooves, so that the movement of the sliding block 4 is used to assist and limit the moving trajectory of the moving tube 5.

[0027] As an implementation method in this embodiment, Figure 1 and Figure 4 As shown, there are two groups of plug-in rods 6, which are respectively located at the top and bottom ends of the moving cylinder 5. The plug-in rods 6 and the moving cylinder 5 are fixedly connected by a spring, and the elasticity of the spring is used to facilitate the movement and resetting of the plug-in rods 6, and the loss of the plug-in rods 6 can also be avoided; the sponge layer 9 is located on the back of the adsorption carbon layer 8, and the adsorption carbon layer 8 and the sponge layer 9 are both adapted to the moving cylinder 5, ensuring that the sponge layer 9 can be used to seal the telescopic ring 3, and the activated carbon layer 8 can be used to adsorb toxic chemicals.

[0028] Working principle: When in use, the telescopic ring 3 is directly pushed manually to expand, so that the telescopic ring 3 will push the automatic telescopic rod 2 to shrink, and then the telescopic ring 3 is directly sleeved on the chemical pipeline, and then the ball on the inner wall of the telescopic ring 3 is used to facilitate the telescopic ring 3 to move on the chemical pipeline, and in this process, the automatic telescopic rod 2 will automatically reset and push the telescopic ring 3 to shrink, so that the telescopic ring 3 shrinks and clamps the chemical pipeline, and then pull the plug rod 6 upward, so that the plug rod 6 will compress the spring, and manually push the moving cylinder 5 to slide on the surface of the sleeve cylinder 1, so that the moving cylinder 5 will drive the sliding block 4 slides in the slide groove on the surface of the sleeve tube 1, so that when the moving tube 5 moves, it will drive the adsorption carbon layer 8 and the sponge layer 9 to move synchronously, so that when the moving tube 5 moves, it will drive the sponge layer 9 to seal the outlet of the telescopic ring 3, and adsorb the toxic chemicals through the activated carbon layer 9. When the moving tube 5 moves to the predetermined position, the plug rod 6 can be released, so that the plug rod 6 will be re-inserted into the groove on the surface of the sleeve tube 1 under the reset action of the spring, so as to achieve the position fixation between the moving tube 5 and the sleeve tube 1, thereby achieving the sealing of the chemical pipeline.
