[0001] The utility model relates to the technical field of rolling high positions, and specifically relates to a flat steel rolling inlet guard assembly. Background Technique

[0002] A guard refers to a device that is installed before and after the roll pass during the section steel rolling process to help the rolled piece enter and exit the roll pass accurately and stably in a predetermined direction and state. Generally speaking, guards are divided into rolling guards and sliding guards. Flat steel is a steel material with a rectangular cross-section and slightly blunt edges, and a rolling inlet guard is required for guiding during rolling.

[0003] In the existing rolling guard assembly, the distance between the two guide rollers is fixed, and it is impossible to adjust the distance of the rolling guard according to the actual use situation of the flat steel, resulting in limitations in the use of the rolling guard. Secondly, the guide roller is a consumable part, and the guide roller will be worn after long-term use and needs to be replaced. In the existing rolling guard, the guide roller is fixed by multiple bolts, making it inconvenient for the staff to replace the guide roller. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a flat steel rolling inlet guide guard assembly, including a bottom plate 1, the upper surface of the bottom plate 1 is fixedly welded to the support plate 2, the upper surface of the support plate 2 is rotatably connected to one end of the connecting shaft 3, the other end of the connecting shaft 3 is rotatably connected to the support plate 2, the outside of the connecting shaft 3 is fixedly welded to the side plate 4, the connecting shaft 3 is located at the end of the side plate 4, a rectangular groove 5 is opened on the upper surface of the bottom plate 1, one end of the threaded rod 6 is rotatably connected to the inside of the rectangular groove 5, the outside of the threaded rod 6 is threadedly connected to the moving block 7, one side of the moving block 7 is hinged to one end of the hinge plate 8, one side of the moving block 7 is fixedly welded to one end of the connecting plate 9, the bottom surface of the side plate 4 is fixedly welded to the slide block 10, the side surface of the side plate 4 is fixedly welded to the mounting plate 11, the mounting plate 11 is rotatably connected to the outside of the first rotating plate 12, a first slot 13 is opened on the upper surface of the first rotating plate 12, the mounting plate 11 is rotatably connected to the outside of the second rotating plate 14, the upper surface of the second rotating plate 14 is fixedly welded to the fixed cylinder 15, a guide roller 16 is arranged on the first rotating plate 12, a second slot 17 is opened at the center of the guide roller 16, a rotating cylinder 18 is arranged on the mounting plate 11, the rotating cylinder 18 is rotatably connected to one end of the insertion plate 19, and the side surface of the support plate 2 is fixedly connected to the guide guard 20.

[0022] In order to facilitate the adjustment of the distance between the guide rollers 16, the side plate 4 is hinged to the upper surface of the bottom plate 1 through the connecting shaft 3. The number of the side plates 4 is two and they are symmetrically distributed. A threaded hole is opened on one side of the moving block 7, and the moving block 7 is threadedly connected to the outside of the threaded rod 6 through the threaded hole. One end of the threaded rod 6 extends to the outside of the bottom plate 1 and is fixedly welded to the hand wheel. By rotating the hand wheel, the threaded rod 6 rotates, so that the moving block 7 moves inside the rectangular groove 5, thereby driving the hinge plates 8 on both sides to make the side plate 4 rotate around the connecting shaft 3 as the center, realizing the adjustment of the distance between the guide rollers 16 on both sides.

[0023] To ensure the synchronous movement of the guide rollers 16 on both sides, the inner part of the rectangular groove 5 is slidably connected to the outer side of the moving block 7. One end of the hinged plate 8 is hinged to the side of the moving block 7 through the hinge groove, and the other end of the hinged plate 8 is hinged to the side of the side plate 4. The side plate 4 is pushed to move through the hinged plate 8. At the same time, a chute is formed on the surface of the connecting plate 9, and the connecting plate 9 is slidably connected to the outer side of the slider 10 through the chute. When the side plate 4 moves, the slider 10 moves inside the chute of the connecting plate 9, and the stability of the side plate 4 during guiding is improved through the connecting plate 9 and the slider 10.

[0024] To reduce the difficulty of replacing the guide roller 16, the mounting plate 11 is slidably connected to the outer side of the rotating plate one 12 through a bearing sleeve. The rotating plate one 12 and the rotating plate two 14 are respectively located on the upper and lower sides of the guide roller 16. The rotating plate one 12 and the rotating plate two 14 are both provided with a slot one 13. The outer side of the inserting plate 19 is movably inserted into the slot one 13 and the slot two 17. The outer side of the fixed cylinder 15 is provided with threads, and a threaded groove is formed inside the rotating cylinder 18. The rotating cylinder 18 is threadedly connected to the outer side of the fixed cylinder 15 through the threaded groove.

[0025] Working principle: When in use, the staff moves one end of the flat steel out of the guide guard 20 under the guidance of the guide rollers 16 on both sides. By rotating the handwheel, the threaded rod 6 rotates, causing the moving block 7 to move inside the rectangular groove 5, thereby driving the hinged plates 8 on both sides to make the side plate 4 rotate around the connecting shaft 3 as the center, realizing the adjustment of the distance between the guide rollers 16 on both sides. When the side plate 4 moves, the slider 10 moves inside the chute of the connecting plate 9, and the stability of the side plate 4 during guiding is improved through the connecting plate 9 and the slider 10. When replacing the guide roller 16, rotate the rotating cylinder 18 to disengage from the outer side of the fixed cylinder 15, and then pull up the rotating cylinder 18 until the inserting plate 19 is successively disengaged from the slot one 13 of the rotating plate one 12 and the inside of the slot two 17. Subsequently, take out the slot two 17 from the rotating plate one 12, place the new guide roller 16 on the surface of the rotating plate one 12, and then pass the slot two 17 through the slot one 13 and the slot two 17 in sequence. Connect the rotating cylinder 18 to the fixed cylinder 15 by rotation and install and fix the guide roller 16. The guide roller 16 will rotate during guiding under the action of the rotating plate one 12 and the rotating plate two 14.
