The mounting column is plugged into the connecting column at the bottom side of the frame. By rotating the actuating bracket and the second bolt to tighten the nut, the abutment ring pushes the end face of the connecting column, causing the mounting column to move outward along the plug-in rod and adjustment hole. The mounting bracket then pushes the gears to mesh and rotate at the top of the toothed plate, pushing and lifting the abutment plate at the top. This causes the outer end of the abutment plate to rotate and lift, securing it against the side of the baffle. Simultaneously, the first bolt passes through the abutment ring and presses against the end face of the connecting column, while the second bolt passes through the actuating bracket and presses against the surface of the connecting column. This ensures a stable and secure mounting connection, allowing the gears to press against the abutment plate, thus securing the outer end of the abutment plate against the baffle. This enhances the strength of the outer bottom of the frame and prevents deformation and bending of the roll mill frame.

[0020] The first reinforcing support mechanism includes an abutment plate 12 rotatably mounted on the bottom outer side of the frame 1, baffles 11 fixed at the four corners of the top of the base 32 to block the outer end of the abutment plate 12, and a gear 20 rotatably mounted on the bottom of the abutment plate 12 to push the abutment plate 12 to rotate.
[0021] The base 32 is horizontally set, and the bottom outer side of the frame 1 is fixed with a first side plate 8. The side of the first side plate 8 has a first connecting hole 15. The top of the abutment plate 12 is slidably inserted between the two first side plates 8. The top side of the plate 12 has a second connecting hole 19. The first connecting hole 15 and the second connecting hole 19 slide through the first screw 9. The two ends of the first screw 9 are connected with nuts.
[0022] A toothed plate 10 is fixed to the top of the base 32. The toothed plate 10 is fixed between the baffle 11 and the frame 1 and is horizontally set. The baffle 11 is vertically set and the outer end of the abutment plate 12 is inclined to abut against the inner side of the baffle 11. The gear 20 is meshed and connected to the top of the toothed plate 10.
[0023] Rotating columns 21 are fixed at both ends of the gear 20. A mounting bracket 22 is installed on one side of the gear 20. The outer end of the rotating column 21 is rotatably connected to both ends of the mounting bracket 22. The mounting bracket 22 has a C-shaped structure and is horizontally set. A mounting column 23 is fixed in the middle of the outer side of the mounting bracket 22. The mounting column 23 has a threaded column structure.
[0024] The mounting bracket 22 drives the gear 20 to mesh and rotate at the top of the toothed plate 10, and pushes up the abutment plate 12 at the top, so that the outer end of the abutment plate 12 rotates and lifts up, and is fastened to the side of the baffle 11.
[0025] A connecting column 14 is fixed to the bottom outer side of the frame 1. An adjustment hole 17 is opened inside the connecting column 14. A plug rod 16 is fixed inside the adjustment hole 17. A plug groove 31 is opened in the middle of the mounting column 23. The mounting column 23 slides into the adjustment hole 17. The plug rod 16 slides into the plug groove 31. Both the plug groove 31 and the plug rod 16 are horizontally set and are rectangular structures.
[0026] A tightening nut 27 is connected to the surface of the mounting post 23. An abutment ring 30 is fixed to one side of the tightening nut 27. The abutment ring 30 is slidably sleeved on the surface of the mounting post 23 and abuts against the end face of the connecting post 14. A third connecting hole 29 is evenly opened on the surface of the abutment ring 30. The third connecting hole 29 is a threaded hole structure, and a first bolt 28 is inserted into the internal thread. The inner end of the first bolt 28 is tightened against the end face of the connecting post 14.
[0027] The two sides of the tightening nut 27 are fixed with a lever 24. The lever 24 has an L-shaped structure and is horizontally slidably set on the outside of the connecting column 14. The outer end surface of the lever 24 has a fourth connecting hole 26. The fourth connecting hole 26 has a threaded hole structure, and a second bolt 25 rotates through it. The inner end of the second bolt 25 is fastened to the surface of the connecting column 14.
[0028] After the roll mill frame is installed on the ground, the gear 20 is installed on the top of the tooth plate 10 through the meshing of the mounting bracket 22 and the mounting column 23. The mounting column 23 is inserted into the connecting column 14 at the bottom side of the frame 1. Therefore, by rotating the tightening nut 27 by turning the actuating bracket 24 and the second bolt 25, the abutment ring 30 is driven to push the end face of the connecting column 14, so that the mounting column 23 moves outward along the insertion rod 16 and the adjustment hole 17.
[0029] The second reinforcing support mechanism includes a support plate 4 rotatably mounted at the top corner of the outer side of the frame 1, a hinge seat 5 hinged to the bottom of the support plate 4, and a pad 7 fixedly mounted to the bottom of the hinge seat 5 for fastening and stabilizing the installation on the ground.
[0030] The outer top of the frame 1 is fixed with a second side plate 2. The surface of the second side plate 2 has a fifth connecting hole 13. The top of the support plate 4 has a sixth connecting hole 18. The top of the support plate 4 is slidably inserted between the two second side plates 2. The second screw 3 slides through the interior of the fifth connecting hole 13 and the sixth connecting hole 18. The two ends of the second screw 3 are fastened and connected with nuts. The support plate 4 is set at an angle. The pad 7 is set horizontally. The two ends of the pad 7 have a seventh connecting hole 6 for connecting with the ground.
[0031] After the roll mill frame is installed on the ground, rotate the support plate 4 so that the bottom pad 7 of the support plate 4 is firmly installed on the ground, keeping the support plate 4 firmly against the top of the outer side of the frame 1, thereby strengthening the top of the frame 1, reducing the loosening, deformation or even bending of the roll mill frame due to vibration during use, and maintaining the stable use of the tube rolling mill.
[0032] Working method: The abutment plate 12 is rotatably installed between the four corners of the top of the base 32 and the bottom outer side of the frame 1. Therefore, after the roll mill frame is installed on the ground, the gear 20 is installed on the top of the tooth plate 10 through the meshing of the mounting bracket 22 and the mounting column 23. The mounting column 23 is inserted into the connecting column 14 at the bottom side of the frame 1. Therefore, by rotating the tightening nut 27 through the actuating bracket 24 and the second bolt 25, the abutment ring 30 is driven to push the end face of the connecting column 14, so that the mounting column 23 moves outward along the insertion rod 16 and the adjusting hole 17, and pushes the gear 20 on the tooth plate through the mounting bracket 22. The top of the gear 10 engages and rotates, pushing and lifting the top abutment plate 12, causing the outer end of the abutment plate 12 to rotate and lift, and to be firmly abutted against the side of the baffle 11. At the same time, the first bolt 28 passes through the abutment ring 30 and abuts against the end face of the connecting column 14, and the second bolt 25 passes through the actuating frame 24 and abuts against the surface of the connecting column 14. Thus, the mounting column 23 is kept firmly and stably connected, which in turn causes the gear 20 to press against the abutment plate 12, thereby allowing the outer end of the abutment plate 12 to be firmly abutted against the baffle 11. In this way, the strength of the bottom outer side of the frame 1 can be enhanced, and deformation and bending of the roll frame can be avoided.
[0033] The support plate 4 is rotated and installed at the outer top corner of the frame 1. After the roll mill frame is installed on the ground, the support plate 4 is rotated so that the bottom pad 7 of the support plate 4 is firmly installed on the ground, keeping the support plate 4 firmly against the outer top of the frame 1, thereby strengthening the top of the frame 1, reducing the loosening, deformation or even bending of the roll mill frame due to vibration during use, and maintaining the stable use of the tube rolling mill.
[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
