Description

Technical Field

[0001] This utility model relates to the field of steel rolling technology for large coil production lines, and in particular to a long shaft support for a movable guide. Background Technology

[0002] During the steel rolling process on a large coil production line, the rolled wire rod is guided into the coiling drum via a bending guide groove and a moving guide. This part of the equipment is interlocked; when the moving guide rotates to its correct position, a proximity switch receives a signal, and the coil inside the coiling drum begins to rise. Therefore, before the coil rises from the coiling drum, the moving guide must rotate to a vertical position; otherwise, the coil will collide with the moving guide, causing equipment damage. Because the moving guide moves back and forth once for each piece of steel rolled, the rotating shaft of the moving guide rubs frequently with the bushing, causing wear on the bushing. Wear reduces the positioning accuracy of the moving guide's ascent or descent, and in severe cases, it can fail, damaging the equipment and causing steel stacking problems.

[0003] Currently, the moving guide rotating shaft and bushing used in the large coil production line have sliding friction, which results in high frictional resistance. During daily use, the equipment wears out severely, the positioning accuracy decreases, and steel stacking failures caused by inaccurate positioning are prone to occur, seriously affecting the normal operation of the production line. Utility Model Content

[0004] The purpose of this utility model is to provide a long shaft support for a mobile guide to overcome the shortcomings of the prior art. The support is equipped with a bearing. By replacing the support of the mobile guide with a support, the rolling friction of the bearing replaces the original sliding friction of the bushing, thereby reducing frictional resistance, improving the positioning accuracy of the mobile guide, and ensuring the normal operation of the large coil production line.

[0005] According to this utility model, a long shaft support for a mobile guide includes a bearing housing and a through cover. The bearing housing includes a first shaft hole, a second shaft hole, and a third shaft hole for accommodating a rotating shaft. A bearing is installed in the third shaft hole, and a rotating shaft is installed in the bearing. The diameters of the first shaft hole, the second shaft hole, and the third shaft hole increase sequentially. The through cover includes a fourth shaft hole and a fifth shaft hole for accommodating a rotating shaft. The left end of the through cover has a protrusion, and the fourth shaft hole is located in the protrusion. The protrusion engages with the third shaft hole. The bearing housing and the through cover are fixed together by bolts.

[0006] Preferably, the bearing housing is provided with a bolt hole.

[0007] Preferably, the cover is provided with a second bolt hole corresponding to the position of the first bolt hole.

[0008] Preferably, the bearing housing is provided with an oil and gas pipe joint leading to the bearing.

[0009] Preferably, the shaft hole contains lubricating oil.

[0010] Preferably, the number of bolts is two or more.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] This support base contains bearings. By replacing the support of the moving guide with this support base, the rolling friction of the bearings replaces the sliding friction of the original bushing, reducing frictional resistance and improving the positioning accuracy of the moving guide. This support base operates sensitively and without jamming, ensuring accurate positioning of the moving guide, greatly reducing the occurrence of steel stacking failures and guaranteeing the normal operation of the large coil production line.

[0023] See Figures 1-2 , Figure 1 This illustration shows a schematic diagram of a long axis support structure for a mobile guide according to one embodiment of this application. Figure 2 The dimensions of each part of the bearing housing in this embodiment are shown. The support base includes a bearing housing 1 and a through cover 2. The bearing housing 1 has a diameter of 240 mm and a thickness of 60 mm. The bearing housing 1 includes a first shaft hole 7, a second shaft hole 8, and a third shaft hole 9 for accommodating a rotating shaft. The first shaft hole 7, the second shaft hole 8, and the third shaft hole 9 are concentric and penetrate through the bearing housing 1. The rotating shaft 14 can pass through the three shaft holes sequentially. The first shaft hole 7 has a diameter of 94 mm and a thickness of 5 mm, the second shaft hole 8 has a diameter of 140 mm and a thickness of 10 mm, and the third shaft hole 9 has a diameter of 160 mm and a thickness of 45 mm. A bearing 3 is installed in the third shaft hole 9, and the rotating shaft 14 is installed in the bearing 3. The through cover 2 includes a shaft hole 4 10 and a shaft hole 5 11 that can accommodate the rotating shaft 14. The shaft hole 4 10 and the shaft hole 5 11 are concentric and pass through the through cover. The rotating shaft 14 can pass through the shaft hole 4 10 and the shaft hole 5 11 in sequence. There is a protrusion 4 at the left end of the through cover 2. The shaft hole 4 10 is located in the protrusion 4. The protrusion 4 is engaged with the shaft hole 3 9. After the protrusion 4 is inserted into the shaft hole 3 9, it can play an axial positioning role for the bearing 3. The bearing box 1 is also provided with an oil and gas pipe connector 6 leading to the bearing 3. The bearing box of the size of this embodiment can be adapted to a rotating shaft with a diameter of 90mm.

[0024] The bearing housing 1 is provided with bolt holes 12, which are located at the end of shaft hole 9. Multiple bolt holes 12 can be provided as needed. The through cover 2 is provided with bolt holes 13, corresponding to the positions of bolt holes 12. Bolt holes 13 are located at the end of shaft hole 11. Multiple bolt holes 13 can be provided as needed. The bearing housing 1 and the through cover 2 are fixed together with bolts 5, with two or more bolts 5. In one embodiment, preferably, six bolts with a diameter of 12mm are used to fix the bearing housing 1 and the through cover 2, combined with... Figure 2 The distance between the centers of the two bolt holes is 190mm.

[0025] Figure 3A schematic diagram of the support base installation position is shown. During installation, first, the bearing 3 is placed into the shaft hole 9. Then, the rotating shaft 14 of the movable guide 15 passes sequentially through the shaft holes 7, 8, 9, and 10 of the cover in the bearing housing 1, and then exits through the shaft hole 11. The protrusion 4 of the cover 2 is inserted into the shaft hole 9 to provide axial positioning for the bearing 3 in the shaft hole 9. The bolt holes 12 and 23 are aligned, and finally, the bolts 5 are inserted and tightened to secure the bearing housing 1 and the cover 2. The bearing housing 1 is equipped with an oil-gas pipe connector 6 leading to the bearing 3, through which lubricating oil can be injected to lubricate the bearing 3. The diameters of the shaft holes 8 and 10 are larger than the diameter of the rotating shaft 14, and the extra space stores lubricating oil, which can better protect the bearing 3 and extend its service life.

[0026] This support base is installed between the moving guide and the tilting arm, replacing the original bushing sliding friction with bearing rolling friction. This reduces frictional resistance and improves the positioning accuracy of the moving guide. The support base operates sensitively and without jamming, ensuring accurate positioning of the moving guide and significantly reducing the occurrence of steel stacking failures, thus guaranteeing the normal operation of the large coil production line.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
