Description

Technical Field

[0001] This utility model relates to the field of high-pressure oil pipe cleaning technology, specifically a high-pressure oil pipe inner wall cleaning mechanism. Background Technology

[0002] High-pressure oil pipes are widely used in machinery and vehicles. After long-term use, oil stains, carbon deposits and other impurities can easily accumulate on the inner wall, which may block the nozzle during operation, causing the nozzle to be unable to close or block the nozzle, resulting in insufficient oil supply. Therefore, it is necessary to use cleaning equipment to clean the high-pressure oil pipes.

[0003] Utility model patent CN219923978U discloses a cleaning device for high-pressure oil pipes, including a panel. A drying mechanism is located at the top of the panel, and a cleaning mechanism is located at the bottom. The cleaning mechanism includes a mixing component and a purification component. The mixing component and the purification component are located at the top of the panel. The drying mechanism includes a heating chamber, which is fixedly installed on the top of the panel. A jet pipe is fixedly installed on the left side of the heating chamber. When purified water is transported into the mixing tank, a valve is manually opened. When the valve is open, cleaning agent is transported into the mixing tank through a pipe at the bottom of the valve. When the cleaning agent and purified water are mixed, an internal agitator is rotated by a motor. This method not only cleans solid impurities but also removes internal oil stains when cleaning high-pressure oil pipes, resulting in a cleaner interior.

[0004] However, the existing technical solutions described above still have the following shortcomings: the cleaning device separates cleaning and drying into two independent steps. After cleaning, the pipes need to be manually disassembled and replaced with drying equipment, which is cumbersome, inefficient, and may introduce secondary pollution. In addition, during the cleaning and drying process, the high-pressure oil pipes are stationary, resulting in incomplete cleaning of the inner wall and poor cleaning effect.

[0005] Therefore, we propose a high-pressure oil pipe inner wall cleaning mechanism to solve the problems mentioned above. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-6 A high-pressure oil pipe inner wall cleaning mechanism includes a base 1, and a rotary drive mechanism 2 and a position adjustment mechanism 3 are provided on the top of the base 1; A liquid storage tank 4 and a hot air blower 5 are fixed on the top of the base 1. A delivery pump 6 is connected to the surface of the liquid storage tank 4. The output ends of both the delivery pump 6 and the hot air blower 5 are connected to a first three-way pipe 7. Two first solenoid valves 8 are installed on the surface of the first three-way pipe 7. A first support plate 9 is fixed on the top of the base 1. A first rotary joint 10 is fixed on the surface of the first support plate 9. The fixed end of the first rotary joint 10 is connected to one end of the first three-way pipe 7. The other end of the first rotary joint 10 is connected to a first connector pipe 11. A movable plate 12 is set above the base 1. A second support plate 13 is fixed on the top of the movable plate 12. A second rotary joint 14 is fixed on the surface of the second support plate 13. The rotating end of the second rotary joint 14 is connected to a second connector pipe 15. The fixed end of the second rotary joint 14 is connected to a second three-way pipe 16. Two second solenoid valves 17 are connected to the surface of the second three-way pipe 16. A controller 25 is fixed on the top of the base 1.

[0022] Through the above technical solution, the rotary drive mechanism 2 and the position adjustment mechanism 3 work together to realize the rotation of the high-pressure oil pipe and adapt to high-pressure oil pipes of different lengths. The liquid tank 4 stores the cleaning fluid and delivers it through the delivery pump 6. The hot air blower 5 provides hot air for drying. The first three-way pipe 7 and the first solenoid valve 8 control the flow direction of the cleaning fluid or hot air. The first rotary joint 10 allows the first connector pipe 11 to maintain fluid communication when rotating. The movable plate 12 moves through the position adjustment mechanism 3 to adapt to high-pressure oil pipes of different lengths. The second rotary joint 14 and the second connector pipe 15 connect to the other end of the high-pressure oil pipe. The second three-way pipe 16 and the second solenoid valve 17 control the discharge of waste liquid or waste gas. The controller 25 integrates the control of the entire process to realize automated operation.

[0023] A water collection tank 18 is provided on one side of the base 1. A flexible hose 19 is connected above the surface of the water collection tank 18. One end of the flexible hose 19 is connected to the second three-way pipe 16. A drain valve 24 is connected to the surface of the water collection tank 18.

[0024] Through the above technical solution, the water collection tank 18 is connected to one end of the second three-way pipe 16 via the hose 19 to collect the waste liquid generated during the cleaning process. When the cleaning mode is started, the waste liquid flows from the high-pressure oil pipe into the second three-way pipe 16 and enters the water collection tank 18 for temporary storage through the hose 19. The drain valve 24 is used to periodically discharge the accumulated waste liquid to ensure the continuous operation of the system. The flexible design of the hose 19 allows the movable plate 12 to move without affecting the collection of waste liquid, maintaining the continuity and stability of the system.

[0025] A support frame 22 is fixed above the middle of the inner wall of the water collection tank 18, and a filter screen 23 is slidably connected to the top of the support frame 22.

[0026] Through the above technical solution, the filter screen 23 is slidably connected to the top of the support frame 22. When the waste liquid flows from the hose 19 into the water collection tank 18, the filter screen 23 intercepts solid impurities and prevents them from entering the subsequent circulation or discharge system. The filter screen 23 can be slidably disassembled, which is convenient for regular cleaning or replacement and ensures long-lasting filtration effect. The support frame 22 provides stable support and prevents the filter screen 23 from shifting under the impact of liquid flow, thus ensuring the continuity and efficiency of waste liquid treatment.

[0027] The rotary drive mechanism 2 includes four first bearings 201 with mounting brackets. The two first bearings 201 on the left are fixed to the top of the base 1, and the two first bearings 201 on the right are fixed to the top of the movable plate 12. Worms 202 are fixed to the inner rings of the first bearings 201 on both the front and rear sides. Worm wheels 203 are meshed on the surface of the worms 202. The worm wheel 203 on the left is fixed to the surface of the first connector tube 11, and the worm wheel 203 on the right is fixed to the surface of the second connector tube 15. A drive structure is provided above the base 1.

[0028] Through the above technical solution, the rotary drive mechanism 2 fixes the worm 202 through four first bearings 201 with mounting brackets. The worm 202 meshes with the worm wheel 203 for transmission. The left worm wheel 203 drives the first connector tube 11 to rotate, and the right worm wheel 203 drives the second connector tube 15 to rotate, thereby making the high-pressure oil pipe rotate evenly during the cleaning and drying process. The drive structure provides power to ensure the synchronous movement of the worm 202 and the worm wheel 203, realizing the smooth rotation of the oil pipe. The first bearings 201 with mounting brackets reduce friction and wear, and improve transmission efficiency.

[0029] The drive mechanism above the base 1 includes a first motor 206 and two second bearings 204. The first motor 206 and the left second bearing 204 are fixed to the top of the base 1, and the right second bearing 204 is fixed to the top of the movable plate 12. A connecting rod 205 is fixed to the inner ring of the second bearing 204. The output shaft of the first motor 206 is fixedly connected to the left end surface of the left connecting rod 205. A telescopic coupling 207 is fixed between the left and right connecting rods 205. A first bevel gear 208 is fixed to the surface of the connecting rod 205. A second bevel gear 209 meshes with the surface of the first bevel gear 208. The second bevel gear 209 is fixed to the surface of the worm gear 202.

[0030] Through the above technical solution, the power output of the first motor 206 is transmitted through the connecting rod 205. The telescopic coupling 207 adapts to the distance changes caused by the movement of the movable plate 12. The first bevel gear 208 and the second bevel gear 209 transmit the power to the worm gear 202, driving the worm wheel 203 to rotate, thereby driving the joint pipe to rotate. The second bearing 204 supports the connecting rod 205 to ensure the smoothness of power transmission. The controller 25 adjusts the speed of the first motor 206 to achieve an adjustable rotation mode. The whole process adapts to different working conditions and ensures efficient transmission through the cooperation of gears and couplings.

[0031] The position adjustment mechanism 3 includes an electric cylinder 301, which is fixed to the top of the base 1. Two slide rails 302 are fixed to the top of the base 1. Two sliders 303 are slidably connected to the surface of the slide rails 302. The top of the sliders 303 is fixedly connected to the bottom of the movable plate 12. One end of the electric cylinder 301 is fixedly connected to the surface of the movable plate 12.

[0032] With the above technical solution, when the length of the high-pressure oil pipe changes, the electric cylinder 301 controls the extension and retraction through the controller 25 to adjust the position of the movable plate 12, so that the distance between the second connector pipe 15 and the first connector pipe 11 can be adjusted to adapt to oil pipes of different lengths; the slide rail 302 and the slider 303 provide guidance and support to prevent the movable plate 12 from shifting. The whole process is highly automated, responds quickly, and adapts to various oil pipe sizes.

[0033] A second motor 20 is fixed on the top of the liquid storage tank 4. The output shaft of the second motor 20 passes through the inside of the liquid storage tank 4 and is fixed with a stirring rod 21.

[0034] With the above technical solution, when the cleaning solution is stored in the storage tank 4, the second motor 20 drives the stirring rod 21 to rotate, mix the cleaning agent and water, ensure the solution is uniform, prevent sedimentation, and improve the cleaning effect.

[0035] The worm 202, worm wheel 203, first bevel gear 208 and second bevel gear 209 are all made of stainless steel.

[0036] Through the above technical solutions, stainless steel improves the corrosion resistance and wear resistance of transmission components, extends the service life of the overall equipment, and reduces maintenance frequency and costs; at the same time, the high strength of stainless steel ensures stability under high pressure and rotation, avoiding the risk of deformation or breakage; the corrosion resistance makes the equipment suitable for harsh environments.

[0037] The specific working principle of this utility model is as follows: First, the electric cylinder 301 of the position adjustment mechanism 3 drives the movable plate 12 to move along the slide rail 302. Guided by the slider 303, the distance between the second connector tube 15 and the first connector tube 11 is adjusted to accommodate high-pressure oil pipes of different lengths and achieve quick clamping. Then, the high-pressure oil pipe is installed onto the surfaces of the first connector tube 11 and the second connector tube 15. The rotation drive mechanism 2 is started, and the first motor 206 transmits power through the connecting rod 205 and the telescopic coupling 207. The first bevel gear 208 and the second bevel gear 209 direct the power to the worm gear 202. The worm gear 202 meshes with the worm wheel 203, causing the first connector tube 11 and the second connector tube 15 to rotate synchronously, so that the high-pressure oil pipe rotates evenly during cleaning and drying. During cleaning, the controller 25 turns on the front first electromagnetic switch. Valve 8 and the second solenoid valve 17, and the delivery pump 6 draw premixed cleaning liquid from the storage tank 4, which flows into the inner wall of the high-pressure oil pipe through the first three-way pipe 7 and the first rotary joint 10. Waste liquid is discharged into the water collection tank 18 through the second rotary joint 14 and the second three-way pipe 16 via the hose 19. The filter screen 23 intercepts solid impurities, and the drain valve 24 discharges periodically. During air drying, the controller 25 switches the first solenoid valve 8 and the second solenoid valve 17. The hot air generated by the hot air blower 5 is blown into the oil pipe through the same path, and the waste gas is discharged through the second three-way pipe 16. The entire process is automatically coordinated by the controller 25, achieving seamless switching between cleaning, air drying, and rotation, ensuring efficient and thorough cleaning, solving the problems of cumbersome manual operation, uneven cleaning, and secondary pollution, and improving the automation level and reliability of the equipment.

[0038] In summary, this utility model presents a high-pressure oil pipe inner wall cleaning mechanism. By integrating a rotary drive mechanism and a position adjustment mechanism, it achieves multi-length adaptation and rotation of high-pressure oil pipes, ensuring uniform coverage of the inner wall by cleaning fluid and hot air, significantly improving cleaning efficiency and uniformity, and avoiding cleaning dead zones caused by traditional manual operation. Simultaneously, the use of stainless steel transmission components such as worm gears and worm wheels enhances wear and corrosion resistance, extends equipment lifespan, and reduces maintenance requirements. The electric cylinder and slide rail adapt to oil pipes of different lengths, reducing replacement time and improving equipment utilization. The stirring mechanism in the liquid storage tank ensures uniform mixing of the cleaning fluid, improving the cleaning effect. Meanwhile, the water collection tank and filter screen achieve efficient waste liquid treatment and environmentally friendly discharge. This invention solves key problems in high-pressure oil pipe inner wall cleaning, such as low efficiency and secondary pollution caused by manual switching. Automated processes enable continuous operation, significantly improving production efficiency. The rotation function further enhances cleaning capabilities, reduces cleaning agent waste, and lowers overall operating costs, providing an efficient and reliable solution for the industrial cleaning field.
