Description
Technical Field
[0001] This utility model relates to the field of cold-drawn steel pipe cleaning technology, and in particular to a hoisting cleaning device for precision welded cold-drawn steel pipes. Background Technology
[0002] In modern industrial manufacturing, cold-drawn steel pipes are widely used in various industries such as machinery manufacturing, petrochemicals, and aerospace due to their high precision, high strength, and excellent surface quality. In the production process of precision welded cold-drawn steel pipes, hoisting and cleaning is a crucial step, directly affecting the welding quality and subsequent performance of the pipes. Therefore, developing an efficient, stable hoisting and cleaning device that can adapt to steel pipes of different specifications is of great significance for improving the production quality and efficiency of cold-drawn steel pipes.
[0003] Currently, most existing precision welded cold-drawn steel pipe hoisting and cleaning devices on the market employ fixed-size clamping structures, using hydraulically driven jaws to secure the steel pipe. The technical principle is to utilize the pressure generated by the hydraulic system to push the jaws inward, thereby clamping the steel pipe. During hoisting, a crane or other lifting equipment lifts the device and the steel pipe together, and then the steel pipe is immersed in a cleaning solution for cleaning. This type of device, to a certain extent, meets the hoisting and cleaning needs of cold-drawn steel pipes.
[0004] Existing devices cannot be flexibly adjusted according to changes in the diameter of steel pipes and can only be adapted to steel pipes of specific specifications. When steel pipes of different diameters need to be processed, the clamping structure needs to be frequently replaced or adjusted, which increases the complexity of operation and time cost. To address this issue, a hoisting and cleaning device for precision welded cold-drawn steel pipes is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a hoisting and cleaning device for precision welded cold-drawn steel pipes, which aims to improve the problem that the existing technology can only be used for steel pipes of specific specifications, and that the clamping structure needs to be frequently changed or adjusted when steel pipes of different diameters need to be processed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A hoisting and cleaning device for precision welded cold-drawn steel pipes includes a hanger, a slide rail fixedly connected to the lower surface of the hanger, a connecting plate slidably connected inside the slide rail, an electric hoist fixedly connected to the lower surface of the connecting plate, a hoisting plate provided on the lower surface of the electric hoist, a fixing component provided inside the hoisting plate, a cleaning box provided on the side wall of the hanger, and a filter component provided on the side wall of the cleaning box.

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the screw is driven by a motor to rotate, which drives the fixed plate to move linearly along the telescopic rod. The fixed plate pushes the rotating bar to rotate around the connecting rod through the connecting bar, so that the clamping plate closes and clamps the steel pipe, realizing the clamping of steel pipes of different sizes.

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.
[0035] Reference Figures 1-3 This utility model provides an embodiment of a hoisting and cleaning device for precision welded cold-drawn steel pipes, including a hanger 1, which provides stable support for the entire hoisting system. A slide rail 2 is fixedly connected to the lower surface of the hanger 1, and a connecting plate 3 is slidably connected inside the slide rail 2. An electric hoist 4 is fixedly connected to the lower surface of the connecting plate 3, which is used to lift and lower the steel pipe via a hoisting rope. A hoisting plate 5 is provided on the lower surface of the electric hoist 4, and a fixing component is provided inside the hoisting plate 5. The fixing component is used to stably clamp steel pipes of different sizes, ensuring the smooth progress of the cleaning work and the cleaning quality of the steel pipes. A cleaning tank 14 is provided on the side wall of the hanger 1, which is used to hold the cleaning liquid and the steel pipe to be cleaned, providing a place for cleaning the steel pipes. A filter component is provided on the side wall of the cleaning tank 14 to filter the water flow and achieve recycling.
[0036] The fixing assembly includes a clamping plate 10, located below the lifting plate 5. The clamping plate 10 directly contacts and clamps the steel pipe surface. By adjusting the position and clamping force of the clamping plate 10, it can accommodate steel pipes of different diameters, achieving stable clamping of the steel pipe. A connecting rod 6 is fixedly connected inside the lifting plate 5. A rotating bar 7 is rotatably connected to the side wall of the connecting rod 6. The rotating bar 7 rotates in conjunction with the connecting rod 6, changing the angle and position of the clamping plate 10 to adjust the clamping range according to the diameter of the steel pipe. The side wall of the clamping plate 10 is fixedly connected to the side wall of the rotating bar 7. A motor 11 is fixedly connected inside the lifting plate 5, providing power to the fixing assembly. A screw 12 is fixedly connected to the output end of the motor 11, converting the rotational motion of the motor 11 into linear motion. A fixing plate 8 is threadedly connected to the side wall of the screw 12, moving linearly under the drive of the screw 12. A connecting bar 9 is rotatably connected inside the fixing plate 8, with one end rotatably connected to... The rotating bar 7 and the connecting bar 9 work together with the fixed plate 8 and the rotating bar 7 to perform a linkage movement, converting the linear motion of the fixed plate 8 into the rotational motion of the rotating bar 7, thus achieving the effect of transmitting power and controlling the opening and closing angle of the clamping plate 10. A telescopic rod 13 is fixedly connected to the upper surface of the fixed plate 8. The upper end of the telescopic rod 13 is fixedly connected to the lower surface of the lifting plate 5. The telescopic rod 13 is used to provide guidance and support for the movement of the fixed plate 8, ensuring that the fixed plate 8 remains stable during the movement. At the same time, it plays an auxiliary role in stabilizing the transmission of the screw 12, making the opening and closing action of the clamping plate 10 more stable and reliable. An ultrasonic generator 15 is fixedly connected to the side wall of the cleaning tank 14. The ultrasonic generator 15 is used to generate high-frequency electrical signals to provide energy for ultrasonic cleaning. A transducer 16 is set inside the cleaning tank 14. The transducer 16 is made of piezoelectric ceramic material. Its function is to convert the high-frequency electrical signals generated by the ultrasonic generator 15 into mechanical vibrations, forming ultrasonic waves in the cleaning fluid, generating a cavitation effect, thereby achieving efficient cleaning of dirt on the surface of the steel pipe.
[0037] Reference Figures 4-6The filtration assembly includes a filter box 17, which is used to contain and filter the waste liquid discharged from the cleaning tank 14, extending the service life of the cleaning liquid. The side wall of the filter box 17 is fixedly connected to the side wall of the cleaning tank 14. A connecting pipe 18 is fixedly connected to the side wall of the cleaning tank 14, guiding the waste liquid in the cleaning tank 14 into the filter box 17. One end of the connecting pipe 18 is fixedly connected to the inside of the filter box 17. A water pump 19 is fixedly connected to the side wall of the filter box 17, providing power for the circulation of the cleaning liquid. The water pump 19 draws the filtered cleaning liquid from the filter box 17 and returns it to the cleaning tank 14. The cleaning tank 14 continuously circulates the cleaning fluid, ensuring a constant supply of clean fluid to clean the steel pipes, thus improving cleaning efficiency and quality. A delivery pipe 20 is fixedly connected to the output end of the water pump 19, which transports the cleaning fluid drawn by the pump 19 into the cleaning tank 14. One end of the delivery pipe 20 is located inside the cleaning tank 14. A mounting bracket 22 is fixedly connected inside the filter box 17, and a filter screen 21 is slidably connected inside the mounting bracket 22. The filter screen 21 intercepts impurities in the wastewater, separating iron filings, oil particles, etc., through its fine mesh structure, allowing the wastewater to pass through smoothly. The cleaning solution for filter screen 21 becomes clean, achieving filtration and purification of the cleaning solution. A fixing shell 23 is fixedly connected to the side wall of the mounting bracket 22. An insert block 24 is slidably connected inside the fixing shell 23. The insert block 24 moves linearly with the fixing shell 23, and by inserting into the slot inside the filter screen 21, it achieves the effect of fixing the filter screen 21 and preventing the filter screen 21 from shifting or loosening during the filtration process. The side wall of the insert block 24 is slidably connected to the inside of the filter screen 21. A pull plate 25 is fixedly connected to one end of the insert block 24. The pull plate 25 is used to facilitate the operator to manually pull the insert block 24 to remove the insert block 24 from the filter screen 21. This design facilitates the disassembly and replacement of the filter screen 21, improving the ease of maintenance. A fixing ring 27 is fixedly connected to the side wall of the insertion block 24. The side wall of the fixing ring 27 is slidably connected inside the fixing shell 23, ensuring that the fixing ring 27 can slide stably within the fixing shell 23. A spring 26 is sleeved on the side wall of the insertion block 24. The spring 26 provides elastic force. When the insertion block 24 is inserted into the filter screen 21, the spring 26 is compressed to generate elastic force, causing the insertion block 24 to be tightly inserted into the slot of the filter screen 21, ensuring that the filter screen 21 is firmly fixed. When the pull plate 25 is pulled, the spring 26 is stretched, providing power for the reset of the insertion block 24.
[0038] Working Principle: When using this equipment, the electric hoist 4 first slides along the slide rail 2 to the top of the steel pipe to be hoisted. The hoisting plate 5 then lowers it to a suitable position. The motor 11 drives the screw 12 to rotate, causing the fixed plate 8 to move linearly along the telescopic rod 13. The fixed plate 8, through the connecting strip 9, pushes the rotating strip 7 to rotate around the connecting rod 6, causing the clamping plate 10 to close and clamp the steel pipe. The telescopic rod 13 ensures the smooth movement of the fixed plate 8, preventing the threaded parts from jamming. The electric hoist 4 then lifts the steel pipe into the cleaning tank 14, immersing it in the cleaning solution. The ultrasonic generator 15 generates a high-frequency electrical signal, which is converted into mechanical vibration by the transducer 16. The transducer 16 creates a cavitation effect in the cleaning solution, generating tiny bubbles that burst instantly, impacting impurities on the surface of the steel pipe. The quality, vibration frequency and amplitude can be precisely adjusted by the ultrasonic generator 15 to adapt to steel pipes of different diameters and contamination levels. Then, the water pump 19 is started to pump the sewage in the cleaning tank 14 into the filter tank 17 through the connecting pipe 18. When the sewage flows through the filter screen 21, impurities are intercepted, and the cleaning liquid flows back to the cleaning tank 14 through the delivery pipe 20. The mounting bracket 22 realizes the quick positioning and sliding disassembly of the filter screen 21 through the dovetail groove structure. When the filter screen 21 needs to be replaced, pull the pull plate 25 outward, the insert block 24 compresses the spring 26 to disengage from the filter screen 21 slot, and the filter screen 21 is pulled out along the mounting bracket 22. After replacing the new filter screen 21, release the pull plate 25, the spring 26 pushes the fixing ring 27 to reset the insert block 24 and insert it into the positioning hole of the filter screen 21 to lock it.
