Description

Seamless steel pipe inner wall cleaning tool without disassembly Technical Field

[0001] This utility model relates to the field of steel pipe cleaning technology, and in particular to a tool for cleaning the inner wall of seamless steel pipes without disassembly. Background Technology

[0002] Seamless steel pipes, as an important type of pipe material, are widely used in many fields such as petroleum, chemical, power, and machinery manufacturing. In oil transportation, they undertake the long-distance transportation of crude oil and refined oil. In chemical production, they are key channels for various chemical reactions and material transportation. In the power industry, they are used for steam and water transportation to ensure the normal operation of power generation equipment. In the machinery manufacturing field, they are also often used to manufacture various mechanical parts. However, during long-term use, the inner wall of seamless steel pipes will inevitably accumulate dirt. The sources of this dirt are diverse. In oil transportation, impurities, waxes, and silt in crude oil will adhere to the pipe wall. In chemical production, reaction products and catalyst residues will gradually deposit. In water transportation systems, calcium and magnesium ions and microorganisms in the water will form scale and biofilm. The accumulation of dirt will not only reduce the inner diameter of the pipe and increase the resistance of fluid transportation, leading to a significant increase in energy consumption, but will also cause corrosion, seriously threatening the safe operation of the pipeline and shortening its service life.

[0003] Traditional methods for cleaning the inner walls of seamless steel pipes, involving manual brushing and soaking in chemical cleaning solutions, have many drawbacks. Manual brushing is extremely inefficient and difficult to guarantee cleaning quality, easily leaving cleaning dead spots. Chemical cleaning is not only costly but also causes serious environmental pollution. Furthermore, fixing different steel pipes requires disassembling and fixing equipment, which not only consumes a lot of manpower, resources, and time but also affects the normal operation of the entire production system, causing losses. Using a clamping structure to fix different steel pipes can effectively clean the dirt on the inner walls of different steel pipes. However, for non-circular steel pipes, the clamping structure is difficult to fit well with the surface of the steel pipe and cannot provide uniform fixing force. This makes the steel pipe prone to displacement during the cleaning process, making it difficult to guarantee the comprehensiveness and uniformity of the cleaning. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a tool for cleaning the inner wall of seamless steel pipes without disassembly. It aims to improve the existing technology, which has the problem that it is difficult to make good contact with the surface of non-circular steel pipes and cannot provide uniform fixing force, making it easy for the steel pipe to shift during the cleaning process and making it difficult to ensure the comprehensiveness and uniformity of the cleaning.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please refer to Figures 1, 3, and 4. One embodiment of this utility model provides a tool for cleaning the inner wall of seamless steel pipes without disassembly.

A motor 8 is connected, and a gear 9 is fixedly connected to the output end of the motor 8. Two T-blocks 10 are slidably connected to the left side of the motor 8. A toothed strip 11 is fixedly connected to each adjacent side of the T-block 10. The outer wall of the toothed strip 11 meshes with the outer wall of the gear 9. A locking plate 12 is fixedly connected to each opposite side of the T-block 10. A steel pipe fitting 13 is locked between adjacent locking plates 12. A telescopic rod 14 is fixedly connected to the middle of the left side of the support platform 7. A locking disc 15 is fixedly connected to the other end of the telescopic rod 14. A cleaning mechanism 2 is provided on the top of the support plate 3. The cleaning mechanism 2 is used to clean the inner wall of the steel pipe.

[0032] Specifically, a telescopic rod 4 is fixedly connected to the middle right side of support plate 2 3, and a bearing plate 5 is fixedly connected to the other end of telescopic rod 4, providing a platform for placing the steel pipe. Two fixing plates 6 are fixedly connected to the left side of support plate 2 3. The outer wall of the bearing plate 5 and the adjacent positions of the fixing plates 6 can be slidably connected, so that the bearing plate 5 can be removed after the steel pipe is fixed, so that the steel pipe is suspended in the air for easy cleaning. The outer wall of the toothed strip 11 meshes with the outer wall of the gear 9, ensuring stability and accuracy during operation. Steel pipe fittings 13 are engaged between adjacent clamping plates 12, ensuring the stable fixation of steel pipe fittings 13 during the cleaning process and avoiding incomplete cleaning and damage to the inner wall of the steel pipe caused by the movement of steel pipe fittings 13. A telescopic rod 2 14 is fixedly connected to the middle left side of support platform 7, and a clamping disc 15 is fixedly connected to the other end of telescopic rod 2 14. The cooperation and fixation of the clamping disc 15 allows the steel pipe fittings 13 to be more effectively fixed in the appropriate position, thereby carrying out efficient cleaning operations.

[0033] Please refer to Figures 1, 2 and 5. The cleaning mechanism 2 includes a support plate 201. The bottom left side of the support plate 201 is fixedly connected to the top of the support plate 3. A liquid storage tank 202 is fixedly connected to the top left side of the support plate 201. A connecting pipe 203 is connected to the bottom right side of the liquid storage tank 202. A high-pressure pump 204 is fixedly connected to the middle of the connecting pipe 203. The bottom of the high-pressure pump 204 is fixedly connected to the top right side of the support plate 201. A telescopic pipe 205 is connected to the right end of the connecting pipe 203. A sprayer 206 is connected to the right end of the telescopic pipe 205.

[0034] Specifically, support plate 1 201 is a structural support point capable of withstanding certain pressure and weight. The bottom left side of support plate 1 201 is fixedly connected to the top of support plate 2 3, ensuring the stability of the entire cleaning mechanism 2. The liquid storage tank 202 stores the liquid used for cleaning operations. A connecting pipe 203 connects to the bottom right side of the liquid storage tank 202, enabling it to withstand the transport of high-pressure liquid. The high-pressure pump 204 is the power source for the entire cleaning mechanism 2; it can transport the liquid in the liquid storage tank 202 to the injector 206 under high pressure. The bottom of the high-pressure pump 204... It is also fixedly connected to the top right side of the support plate 201 to ensure the stable operation of the high-pressure pump 204. The telescopic tube 205 can adapt to different cleaning environments. The right end of the telescopic tube 205 is connected to the injector 206. The injector 206 is responsible for spraying the high-pressure liquid through the nozzle 207. The nozzle 207 can spray the high-pressure liquid evenly to the area to be cleaned. A top plate 208 is fixedly connected to the middle of the nozzle 207. This top plate 208 is to prevent the liquid from splashing out during the cleaning process and can effectively control the spray range of the liquid.

[0035] Please refer to Figures 2, 4 and 5. A display screen 24 is fixedly connected to the top of the high-pressure pump 204. An anti-slip sleeve 25 is fixedly connected to the outer wall of the injector 206. A button 26 is fixedly connected to the front top of the injector 206. An adaptive sleeve 27 is fixedly connected to the bottom of the capping plate 208. A waste liquid collection tank 18 is fixedly connected to the top center of the bottom plate 1. A liquid outlet pipe 19 is connected to the rear right end of the waste liquid collection tank 18.

[0036] Specifically, the display screen 24 can display the working status and related parameters of the high-pressure pump 204 in real time, providing an intuitive operating interface for the operator. A non-slip sleeve 25 is fixedly connected to the outer wall of the injector 206 to ensure that the injector 206 can be firmly held during use, thereby improving the safety and comfort of operation. The start and stop of the injector 206 can be controlled by pressing the button 26, making operation more convenient. The adaptive sleeve 27 can be adjusted according to different usage environments and conditions to ensure the stability and sealing of the top plate 208. The main function of the waste liquid collection tank 18 is to collect the waste liquid generated during use to maintain the cleanliness of the working environment. Through the outlet pipe 19, the waste liquid can be guided to a designated location for treatment and recycling, thereby achieving environmental protection and rational utilization of resources.

[0037] Please refer to Figures 1, 2 and 3. A valve 22 is fixedly connected to the top left end of the connecting pipe 203. A nameplate 23 is fixedly connected to the right side of the support plate 201. An anti-slip pad 16 is fixedly connected to the bottom of the base plate 1. A protective sleeve 17 is fixedly connected to the left side of the locking disc 15. An observation window 20 is fixedly connected to the front side of the liquid storage tank 202. A scale plate 21 is fixedly connected to the right side of the observation window 20. The rear side of the scale plate 21 is fixedly connected to the front right end of the liquid storage tank 202.

[0038] Specifically, valve 22 is designed to control fluid flow. The nameplate 23 will indicate relevant equipment information for identification and understanding. Anti-slip pad 16 can effectively prevent the equipment from sliding during use, ensuring safety. Protective cover 17 is to protect the clamping disc 15 from damage to the steel pipe during use. Observation window 20 allows for direct observation of the liquid level in storage tank 202, and a scale plate 21 is fixedly connected to its right side. The liquid level seen through observation window 20, combined with the scale on scale plate 21, makes it easy to read the liquid volume and facilitate timely replenishment.

[0039] Working principle: After the steel pipe fitting 13 is placed on top of the bearing plate 5, the motor 8 drives the gear 9 to rotate. The rotation of the gear 9 causes the meshing toothed strip 11 to rotate, thereby moving the T-block 10 towards each other, and then moving the locking plate 12. At the same time, the telescopic rod 14 drives the locking disc 15 to achieve triangular fixation of the steel pipe fitting 13. This allows force to be applied to the steel pipe fitting 13 from multiple directions, keeping it stable during the cleaning process and preventing shaking and displacement from affecting the cleaning effect, or even causing damage to cleaning tools and hindering the cleaning work. The position and extension degree of the T-block 10 and the locking disc 15 can be adjusted to adapt to different situations. The steel pipe fittings 13 with different diameters, lengths, and shapes improve the equipment's versatility for various specifications of steel pipe fittings 13, reduce the need to replace fixing devices due to different specifications of steel pipe fittings 13, reduce costs, and improve work efficiency. After fixing, the support plate 5 is moved by the telescopic rod 4 to move the support plate 5 away, suspending the steel pipe fitting 13 to facilitate cleaning of the inner wall of the steel pipe fitting 13. Waste residue and waste liquid generated during the cleaning process can fall directly from the inside of the steel pipe fitting 13 without being blocked by the support plate 5, which is conducive to the discharge and collection of waste residue and waste liquid, reduces the cleaning work during the cleaning process, and also reduces the risk of secondary pollution of the cleaned parts by waste residue and waste liquid.

[0040] Because the telescopic tube 205 is telescopic and movable, the position of the capping plate 208 can be adjusted to cover the top of the steel pipe fitting 13. Then, the liquid stored in the storage tank 202 is transmitted to the sprayer 206 through the connecting pipe 203 by the high-pressure pump 204, and sprayed onto the inner wall of the steel pipe fitting 13 by the nozzle 207. The capping plate 208 covers the top of the steel pipe fitting 13, which can effectively form a relatively closed space, preventing the high-pressure sprayed storage liquid from splashing out from the top during the cleaning process, avoiding pollution to the surrounding environment, reducing the risk of cleaning personnel being splashed by liquid, improving the safety of the cleaning work and the cleanliness of the working environment, and helping to maintain the stability of the internal cleaning environment of the steel pipe fitting 13. This allows the entire inner wall of the steel pipe fitting 13 to receive a relatively uniform cleaning effect during the cleaning process, avoiding the problem of uneven cleaning intensity caused by the top opening, and facilitating a comprehensive and uniform cleaning effect from the top to the bottom of the steel pipe fitting 13.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
