[0013] 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.

[0014] Please see Figure 1-3This utility model provides a technical solution: a guide base for an inlet guide of a high-speed bar mill, comprising a mounting plate 1. Two sets of parallel connecting grooves 2 are formed along the length of the upper inner side of the mounting plate 1. Two sets of first lugs 3 are slidably connected inside the connecting grooves 2 via clearance fit. Mounting blocks 4 are fixedly connected to the upper part of the first lugs 3 by welding. Threaded holes 5 are formed in the middle of the mounting blocks 4 along the thickness direction for fixing with mounting bolts at the lower part of the guide. A first threaded rod 7 is threadedly connected inside the first lug 3. A first connecting frame 8 is rotatably connected to the outer side of the first threaded rod 7 via a deep groove ball bearing. The left and right sides of the first connecting frame 8 are welded together. Two sets of second lugs 9 are fixedly connected. Two sets of symmetrical second connecting frames 10 are fixedly connected to the lower part of the mounting plate 1 along the width direction by welding. A guide rod 12 is slidably connected inside one side of the second connecting frame 10 through clearance fit. The two ends of the guide rod 12 are fixedly connected to the inside of the second connecting frame 10 on that side by welding, providing left and right adjustment guidance. A second threaded rod 11 is threadedly connected inside the second lug 9 on the other side. The end of the second threaded rod 11 away from the second lug 9 is rotatably connected to the inside of the second connecting frame 10 on the other side through a deep groove ball bearing. Rotating the second threaded rod 11 can drive the first connecting frame 8 to move the mounting block 4 and the guide left and right. The upper part of the mounting plate 1 has two sets of sliding grooves 6 that communicate with the connecting groove 2. The mounting block 4 is slidably connected to the inside of the sliding groove 6 through clearance fit, and cooperates with the first ear 3 of the connecting groove 2 to restrict the rotation of the mounting block 4, ensure that the threaded hole 5 is accurately aligned with the guide mounting hole, and ensure that the upper part of the mounting block 4 is flush with the mounting plate 1. Two sets of symmetrical support plates 13 are fixedly connected to the lower part of the mounting plate 1 along the length direction by welding. A lifting plate 14 is fixedly connected to the lower part of the two sets of support plates 13 by welding. A base 15 is slidably connected to the outside of the lifting plate 14 by clearance fit. The lifting plate 14 is slidably connected to the sliding cavity inside the upper side of the base 15 to realize up and down lifting. The middle part of the lifting plate 14 is connected to a third threaded rod 16 by a thread. The lower part of the third threaded rod 16 is connected to a first bevel gear 17 by a key. The first bevel gear 17 is meshed with a second bevel gear 18 on one side. The tail of the second bevel gear 18 penetrates the side wall of the base 15 and is fixedly connected to a rotating cap 19 by welding. Rotating the rotating cap 19 drives the third threaded rod 16 to rotate through the bevel gear transmission, thereby causing the lifting plate 14 to slide up and down. Two sets of symmetrical rotating shafts 20 are rotatably connected to the lower side of the base 15 via deep groove ball bearings. The upper part of the rotating shaft 20 is connected to a fourth threaded rod 22 via a key. The fourth threaded rod 22 is threaded to the inner side of the lifting plate 14. A transmission belt 21 is sleeved on the lower outer side of the rotating shaft 20 and the third threaded rod 16. The two transmission belts 21 are staggered to ensure that when the third threaded rod 16 rotates, the rotating shaft 20 and the fourth threaded rod 22 are driven to rotate synchronously through the transmission belt 21. The fourth threaded rod 22 and the third threaded rod 16 work together to support the lifting plate 14, distribute the load, and avoid overload deformation of a single threaded rod. An isolation plate 23 is fixedly connected to the lower side of the base 15 by welding. The isolation plate 23 is located below the third threaded rod 16 and the fourth threaded rod 22, above the transmission belt 21, to prevent impurities such as iron oxide chips and lubricating oil from entering the transmission belt and bevel gear during the rolling process, thus avoiding jamming and corrosion.

[0015] Working principle: When using this utility model: according to the position of the lower mounting hole of the guide to be installed, rotate the two sets of first threaded rods 7. The first threaded rods 7 rotate through the deep groove ball bearing, driving the first lug 3 to slide along the connecting groove 2; the mounting block 4 slides synchronously with the first lug 3 along the sliding groove 6 until the threaded hole 5 of the mounting block 4 is precisely aligned with the lower mounting hole of the guide. Stop rotating the first threaded rods 7, and fix the guide to the upper part of the mounting block 4 by passing the bolt through the guide mounting hole and the threaded hole 5, thus completing the initial fixation of the guide; Rotate the second threaded rod 11. The second threaded rod 11 rotates through the deep groove ball bearing, driving the second lug 9 and the first connecting frame 8 to slide along the guide rod 12. The mounting block 4 and the guide move left and right synchronously with the first connecting frame 8. The centering detection device built into the rolling mill is used to observe until the center of the guide is aligned with the center of the rolling mill pass. Stop rotating the second threaded rod 11 to complete the left and right positioning. Rotating the rotating cap 19 causes the second bevel gear 18 to rotate, meshing with the first bevel gear 17 to drive the third threaded rod 16 to rotate. The third threaded rod 16 moves the lifting plate 14 along the base 15 via the threaded transmission belt 21, and simultaneously drives the rotating shaft 20 and the fourth threaded rod 22 to rotate synchronously via the staggered transmission belts 21. The fourth threaded rod 22 and the third threaded rod 16 work together to support the lifting plate 14 and prevent tilting. Adjust the guide height to suit the rolling requirements, stop rotating the rotating cap 19, and complete the upper and lower positioning. Start the high-speed bar mill. The guide is stabilized under the support of the double threaded rod to resist rolling vibration and ensure the straightness and surface quality of the bar.
