Description

Technical Field

[0001] The utility model relates to the technical field of cooling rollers, in particular to a motor direct drive cooling roller which is easy to maintain. Background Technique

[0002] The water-cooled motor is a brushless structure, with excellent load characteristics, good low-speed performance, large starting torque, small starting current, meeting the need of frequent starting of electric vehicles, saving electric energy. The water-cooled high-temperature-resistant special frequency conversion motor is developed and designed based on series motors such as frequency conversion speed regulation, special roller tables and multi-speed furnace motors according to the working conditions of metallurgical continuous casting machines and billet discharging sites. At the same time, water-cooled motors are widely used in coal mine production. According to the publication number: CN208369406U, a motor direct drive cooling roller is disclosed, which includes a water-cooled roller body, on which there are a motor housing, a water inlet, a connecting edge, a water-cooled roller housing, a water seal sleeve, a water outlet, a roller core, a roller core water injection port, an inner layer positioning sleeve of the roller core, a rotating drain pan, a connecting and fixing chuck, a roller core water outlet, fixing screws, and fixing rings. At the bottom of the water-cooled roller body, there is a side connecting flange, and both sides of the side connecting flange are provided with screw fixing holes. The motor housing, water seal sleeve, and rotating drain pan on the water-cooled roller body are fixedly connected through the side connecting flange. The water-cooled roller body is cooled by cooling the roller core and the motor housing with water, and the double water-cooling method can quickly cool down, greatly improving the cooling speed. However, the above technology still has some defects. For example, the outer roller of the existing cooling roller is directly fixed at the top of the central shaft. After long-term use, when the outer roller is damaged, it cannot be replaced, resulting in the situation that it cannot be used continuously, and the practicability is poor, so it needs to be improved.

After long-term use, when it is necessary to replace the outer roll 9, the rotating handle 15 can be pinched and rotated, so that the threaded rod 14 rotates upward inside the fixing block 12 through the rotating groove 13. When the threaded rod 14 completely rotates out of the inside of the fixing block 12 through the rotating groove 13, then the fixing block 12 is pinched and pulled to the left, so that the stop block B 11 slides out of the surface of the central shaft 1, and then the outer roll 9 can be taken out from the surface of the central shaft 1 for replacement, avoiding the situation that the existing cooling roll cannot continue to be used because the outer roll 9 is directly fixed at the top of the central shaft 1 and the outer roll 9 cannot be replaced after long-term use. The rotating cover 3 is rotatably connected to the central shaft 1, and the conduit 4 is rotatably connected to the central shaft 1, which is more convenient for the rotating cover 3 and the conduit 4 to rotate, preventing the situation that the rotating cover 3 and the conduit 4 cannot continue to rotate because the rotating cover 3 and the conduit 4 are stuck by the central shaft 1 during use. The clamping plates 8 are evenly distributed on the surface of the central shaft 1, the outer roll 9 is slidably connected to the clamping plates 8, the outer roll 9 is slidably connected to the stop block A 7, and the clamping groove 10 is slidably connected to the clamping plates 8, which is more convenient for the outer roll 9 to slide, avoiding the situation that the outer roll 9 cannot continue to slide because the outer roll 9 is stuck by the clamping plates 8 during use. The fixing blocks 12 are symmetrically distributed at the upper and lower ends on the left side of the stop block B 11, and the fixing blocks 12 are slidably connected to the central shaft 1, which is more convenient for the fixing blocks 12 to slide, preventing the situation that the fixing blocks 12 cannot continue to slide because the fixing blocks 12 are stuck by the central shaft 1 during use. The threaded rod 14 is rotatably connected to the fixing block 12, the threaded rod 14 is rotatably connected to the central shaft 1, the threaded rod 14 is rotatably connected to the fixing groove 6, and the rotating handle 15 is rotatably connected to the fixing block 12, which is more convenient for the threaded rod 14 to rotate, avoiding the situation that the threaded rod 14 cannot continue to rotate because the threaded rod 14 is stuck by the fixing block 12 or the central shaft 1 during use.

[0026] Embodiment Two

[0027] Please refer to Figures 1-3 Figures 6, a protective cover 16 is slidably connected to the surface of the outer roller 9, a cover plate 17 is slidably connected to the left side of the protective cover 16, a soft pad 18 is fixedly installed on the inner wall of the cover plate 17, a limiting plate 19 is fixedly installed on the left side of the cover plate 17, which is more convenient to protect the outer roller 9 during transportation. Before transportation, first pinch the protective cover 16, align it with the outer roller 9 and pull it to the left. After the protective cover 16 completely slides onto the surface of the outer roller 9, pinch the cover plate 17, align it with the protective cover 16 and pull it to the right. After the cover plate 17 drives the soft pad 18 to completely slide onto the surface of the protective cover 16, the soft pad 18 can firmly clamp the cover plate 17 on the surface of the protective cover 16, thereby preventing the outer roller 9 from being damaged due to being knocked during use. The protective cover 16 is slidably connected to the central shaft 1, the cover plate 17 is slidably connected to the outer roller 9, the soft pads 18 are evenly distributed on the inner wall of the cover plate 17, the soft pads 18 are slidably connected to the protective cover 16, and the limiting plate 19 is slidably connected to the outer roller 9, which is more convenient for the cover plate 17 and the soft pads 18 to slide, and avoids the situation that the cover plate 17 and the soft pads 18 are stuck by the outer roller 9 or the protective cover 16 during use, resulting in the cover plate 17 and the soft pads 18 being unable to slide continuously.

[0028] Working principle: After it is produced, the protective cover 16 can be pinched to correspond to the outer roller 9 and pulled to the left until the protective cover 16 completely slides onto the surface of the outer roller 9. Then, pinch the cover plate 17 and push it to the right corresponding to the left side of the protective cover 16, so that the cover plate 17 drives the soft pad 18 to slide towards the protective cover 16. When the right side of the limit plate 19 touches the left side of the protective cover 16, it is okay. At this time, the soft pad 18 firmly clamps the cover plate 17 on the surface of the protective cover 16. When in use, remove the cover plate 17 and the protective cover 16, fixedly install the central shaft 1 at the required position, and then connect the connecting pipe to the left side of the rotary cover 3 through the water inlet 5 to start using. After long-term use, when maintenance and replacement of the outer roller 9 are required, first remove the central shaft 1, then pinch the rotary handle 15 and rotate it, so that the threaded rod 14 rotates upward through the rotating slot 13 inside the fixed block 12. When the threaded rod 14 completely rotates out of the inside of the fixed block 12 through the rotating slot 13, it can rotate out of the inside of the central shaft 1 through the fixed slot 6. Then, pinch the fixed block 12 and pull it to the left, so that the fixed block 12 drives the stop block B11 to slide to the left on the surface of the central shaft 1. When the stop block B11 completely slides out of the surface of the central shaft 1, it is okay. Then, pinch the outer roller 9 and pull it to the left, so that the right side of the outer roller 9 disengages from the left side of the stop block A7 and the outer roller 9 slides to the left on the surface of the clamping plate 8 through the card slot 10. When the outer roller 9 completely slides out of the surface of the central shaft 1, maintenance or replacement can be carried out. At this time, the operator can also pinch the rotary cover 3 and rotate it, so that the rotary cover 3 rotates to the left through the joint 2. When the rotary cover 3 completely rotates out of the surface of the joint 2, it is okay. Then, the conduit 4 can be taken out of the inside of the central shaft 1 through the rotary cover 3 for maintenance.

[0029] The above are only the preferred embodiments of the present invention, and are not limitations to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
