Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for petrochemical equipment, and in particular to a device for cleaning and oiling threads. Background Technology

[0002] In the petrochemical industry, the installation of oil pipes is a fundamental and crucial task. Oil pipes are connected by threaded connections, and to ensure the sealing and stability of these connections, it is essential to clean and lubricate the pipe threads before installation.

[0003] Existing thread cleaning and lubrication devices primarily utilize a cleaning strip and an lubrication ring to perform their functions. Lubrication nozzles are installed on the inner wall of the lubrication ring. The cleaning brush on the cleaning strip cleans the outer threads of the thread, while simultaneously spraying lubricating oil onto the threads through the lubrication nozzles. However, with existing cleaning brush methods, dust tends to adhere to the brush after each cleaning cycle, potentially affecting the cleaning of subsequent threads. Furthermore, directly spraying lubricating oil onto the threads through the lubrication nozzles makes it difficult to ensure even coverage of the entire thread surface. Some areas may have excessive lubricating oil, resulting in waste, while others may have insufficient oil, failing to provide adequate lubrication and protection. Utility Model Content

[0025] Figure 1 This is a schematic diagram of the structure of the thread cleaning and oiling device in this utility model; Figure 2 yes Figure 1 Enlarged view of point A in the middle; Figure 3 This utility model is a three-dimensional device for cleaning and oiling threads. Figure 1 ; Figure 4This utility model is a three-dimensional device for cleaning and oiling threads. Figure 2 Please see Figures 1 to 4 The diagram illustrates a preferred embodiment of a thread cleaning and oiling device, comprising a base 1, a drive component 2, a mounting base 3, cleaning mechanisms 4, and oiling mechanisms 5. The drive component 2 is located at the lower end of the base 1, and the mounting base 3 is located at the upper end of the base 1. The drive component 2 is connected to the mounting base 3. Two cleaning mechanisms 4 and two oiling mechanisms 5 are located at the upper end of the mounting base 3, facing each other. In this embodiment, the two cleaning mechanisms 4 are used to clamp the external thread segment of the thread, while the two oiling mechanisms 5 are used to clamp the external thread segment of the thread, first cleaning the external thread segment and then applying oil to it. When the two cleaning mechanisms 4 clamp the external thread section, the driving component 2 drives the mounting base 3 to rotate, which in turn drives the cleaning mechanism 4 to rotate, thus cleaning the external thread section. Then the cleaning mechanism 4 releases the external thread section, and the two oiling mechanisms 5 clamp the external thread section again. The driving mechanism drives the mounting base 3 to rotate again, which in turn drives the oiling mechanism 5 to rotate, so that the oiling mechanism 5 evenly applies lubricating oil to the external thread section.

[0026] Furthermore, as a preferred embodiment, the two cleaning mechanisms 4 and the two oiling mechanisms 5 are arranged in a rectangular shape. A support base 6 is provided at the upper end of the base 1, and a mounting base 3 is provided on the support base 6. The mounting base 3 is mounted on the upper end of the base 1 via the support base 6. A rotary joint 7 is provided inside the support base 6, and the rotary joint 7 is connected to the mounting base 3. The driving component 2 includes a hydraulic motor, and the output shaft of the hydraulic motor is connected to the rotary joint 7, which can drive the mounting base 3 and the cleaning mechanism 4 and the oiling mechanism 5 above it to rotate. This arrangement allows the cleaning mechanism 4 and the oiling mechanism 5 to perform all-round cleaning and oiling operations around the threaded external section during operation, further improving work efficiency and processing quality. At the same time, a quick-change connector 8 is provided on one side of the base 1 to facilitate connection with external equipment and improve the versatility and convenience of the device. The quick-change connector 8 is used to connect with the flange at the end of an external six-axis robot arm.

[0027] Furthermore, as a preferred embodiment, the cleaning mechanism 4 includes a first mounting frame 401, a first bracket 402, a first dual-axis cylinder 403, a first mounting block 404, and a cleaning steel brush 405. The first mounting frame 401 is provided at the upper end of the mounting base 3. The first dual-axis cylinder 403 is provided on the first mounting frame 401. The first bracket 402 is provided at the output end of the first dual-axis cylinder 403. The first mounting block 404 is provided inside the first bracket 402. The cleaning steel brush 405 is provided at one end of the first mounting block 404. An air pipe connector 406 is provided on one side of the first mounting block 404, and several air outlets are opened at one end of the first mounting block 404. An air pump can be bolted to the outer wall of the mounting base 3. The air pump is connected to the air pipe connector 406 via an air pipe to pump air into the first mounting block 404, causing the air to be ejected from the air outlet and sprayed onto the cleaning steel brush 405, removing dust adhering to the cleaning steel brush 405. This eliminates the need for manual shutdown, improving work efficiency. In this embodiment, the first mounting block 404 is mounted inside the first bracket 402 with long bolts. The first bracket 402 is bolted to the output end of the first dual-axis cylinder 403. The cleaning steel brush 405 can be welded to the first mounting block 404. The first mounting frame 401 has a slotted hole 407, and an adjusting bolt 408 is installed inside the slotted hole 407. The first mounting frame 401 is connected to the upper end of the mounting base 3 via the adjusting bolt 408, facilitating the adjustment of the position of the first mounting frame 401.

[0028] In this embodiment, see Figure 2 As shown, it also includes a first guide rod 409. A guide hole is provided in the middle of the first dual-axis cylinder 403. One end of the first guide rod 409 is connected to the first bracket 402, and the other end of the first guide rod 409 extends into the guide hole. The first guide rod 409 facilitates the guidance of the first bracket 402 and improves the stability of the movement of the first bracket 402.

[0029] In this embodiment, the cleaning mechanism 4, compared with the traditional cleaning strip, allows the cleaning steel brush 405 to have a closer and more comprehensive contact with the threaded outer wall, thus more effectively removing impurities and dirt.

[0030] Furthermore, as a preferred embodiment, the oiling mechanism 5 includes a second mounting bracket 501, a second dual-axis cylinder 502, a second support 503, a second mounting block 504, and an oiling brush 505. The second mounting bracket 501 is located at the upper end of the mounting base 3. The second dual-axis cylinder 502 is mounted on the second mounting bracket 501. The second support 503 is located at the output end of the second dual-axis cylinder 502. The second mounting block 504 is located inside the second support 503, and the oiling brush 505 is located at one end of the second mounting block 504. In this embodiment, the oiling brush 505 can evenly apply lubricating oil to the outer thread of the thread. The second dual-axis cylinder 502 can precisely control the contact force and movement trajectory between the oiling brush 505 and the thread, ensuring that the lubricating oil evenly covers the entire thread surface. This not only avoids the problem of applying too much or too little oil but also allows the lubricating oil to better penetrate into the thread gaps, improving lubrication and protection effects. A second guide rod is also provided on the second dual-axis cylinder 502 and the second bracket 503 to facilitate the stable movement of the second bracket 503.

[0031] In this embodiment, an oil pipe connector 506 is provided at the upper end of the second mounting block 504. One end of the second mounting block 504 has several oil outlets. The oil pipe connector 506 can be connected to an external oil pump via an oil pipe to inject lubricating oil into the second mounting block 504. The lubricating oil enters the oiling brush 505 from the oil outlets and is absorbed by the oiling brush 505. When the oiling brush 505 contacts the external thread section of the thread, the oiling brush 505 is squeezed, and the internal lubricating oil is applied to the external thread section. The oiling brush 505 can be a sponge brush.

[0032] In this embodiment, a groove is provided in the middle of the upper end of the mounting base 3, which can be used to collect dripping oil and some dust, making it convenient for centralized collection and treatment later.

[0033] In use, the quick-connect coupling 8 is connected to the flange at the end of the external six-axis robot arm, allowing the device to move to the designated position. This allows the threaded section of the external thread to enter between the cleaning mechanism 4 and the oiling mechanism 5. Then, the two first dual-axis cylinders 403 work synchronously, driving the two cleaning steel brushes 405 to adhere to the threaded section. The driving component 2 then drives the mounting base 3 to rotate, which in turn drives the cleaning mechanism 4 to rotate, thus cleaning the threaded section. After cleaning, the two first dual-axis cylinders 403 drive the cleaning steel brushes 405 to reset. Then, the two second dual-axis cylinders 502 work synchronously, driving the two oiling brushes 505 to press against the threaded section. The driving component 2 then drives the mounting base 3 to rotate, which in turn drives the oiling mechanism 5 to rotate, evenly applying lubricating oil to the threaded section. After application, the second dual-axis cylinders 502 drive the oiling brushes 505 to reset.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
