[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: Please refer to Figure 1-3 A small twenty-high rolling mill - intermediate roll transverse shifting mechanism device in this embodiment includes a mounting frame 1 and an intermediate roll 4. A transverse shifting cylinder 2 is arranged on the mounting frame 1. A connecting member 3 is arranged between the transverse shifting cylinder 2 and the intermediate roll 4. The connecting member 3 includes a connecting plate and a mounting seat. The mounting seat is fixedly mounted on one side of the connecting plate. The mounting seat is rotatably connected to one end of the intermediate roll 4. One side of the connecting plate is fixedly connected to the telescopic end of the transverse shifting cylinder 2 to facilitate supporting the rotation of the intermediate roll 4. The transverse shifting cylinder 2 is fixedly mounted on the mounting frame 1. The telescopic end of the transverse shifting cylinder 2 is fixedly connected to one side of the connecting member 3. One end of the intermediate roll 4 is rotatably connected to one side of the connecting member 3.

[0022] By adopting the above technical scheme, it is possible to control the extension and retraction of the transverse cylinder 2 by using the displacement sensor 5, thereby driving the intermediate roller 4 to move laterally through the connecting piece 3, and it is convenient to use the feed assembly 12 to control the fixed block 10 to withdraw from the interior of the positioning frame 9, thereby releasing the fixed connection between the positioning frame 9 and the connecting frame 8, so as to facilitate the staff to disassemble and repair the transverse cylinder 2 and the displacement sensor 5, thereby reducing the labor intensity of the staff. In addition, the structure is simple, the reliability is high, and the transverse force is large, which can well solve the problem of complex structure and high failure rate of the connecting rod push-pull type small twenty-roller intermediate transverse device.

[0023] Example 2: Please refer to Figure 1-3On the basis of the first embodiment, a displacement sensor 5 for controlling the extension and retraction of the transverse cylinder 2 is fixedly installed on one side of the mounting frame 1, and a guide assembly 6 for limiting the moving trajectory of the connecting member 3 is arranged on the top of the mounting frame 1. The guide assembly 6 includes a connecting sleeve and a guide rod. The connecting sleeve is fixedly installed on the top of the mounting frame 1, and the guide rod is slidably connected to the inner wall of the connecting sleeve. One end of the guide rod is fixedly connected to the left side of the connecting plate to limit the moving trajectory of the connecting member 3. A mounting plate 7 is arranged on one side of the mounting frame 1, and a connecting frame 8 is fixedly connected to the left side of the mounting plate 7. A positioning frame 9 located inside the connecting frame 8 is fixedly connected to the outside of the mounting frame 1. Two fixing blocks 10 with one end penetrating and extending to the inside of the connecting frame 8 are slidably installed inside the positioning frame 9. The connecting sleeve and the mounting frame 1 are fixedly connected to the inner wall of the positioning frame 9 respectively. The top and bottom of the positioning frame 9 are provided with grooves, and one end of the fixing block 10 penetrates and extends to the inside of the groove, so that the fixing block 10 is inserted into the groove to connect the positioning frame 9 and the connecting frame 8.

[0024] By adopting the above technical scheme, it is possible to utilize the displacement sensor 5 on one side of the mounting frame 1 to control the extension and retraction of the transverse cylinder 2, so that the transverse cylinder 2 drives the intermediate roller 4 to move laterally through the connecting piece 3. Moreover, during inspection and maintenance, the two fixed blocks 10 can be controlled to move to opposite sides until the fixed blocks 10 exit the grooves provided inside the connecting frame 8, thereby releasing the connection between the connecting frame 8 and the positioning frame 9, and then disassembling the intermediate roller 4 and the connecting piece 3, thereby facilitating the disassembly and inspection of the displacement sensor 5 and the transverse cylinder 2.

[0025] In the implementation of this example, two limit assemblies 11 for limiting the moving range of the fixed block 10 are provided inside the positioning frame 9. The two limit assemblies 11 both include a limit rod and a through slot. The limit rod is fixedly installed inside the positioning frame 9, and the through slot is opened inside the fixed block 10. The outer surface of the limit rod is slidably connected to the inner wall of the through slot, so as to limit the fixed block 10 to move up and down only on the outer surface of the limit rod. The top and bottom of the connecting frame 8 are provided with feed assemblies 12 for controlling the up and down movement of the fixed block 10. The two feed assemblies 12 both include a support frame and an electric push rod. The support frame is fixedly installed on the outer surface of the connecting frame 8, and the electric push rod is fixedly installed on the support frame. The telescopic end of the electric push rod is fixedly connected to one end of the fixed block 10, so as to control the up and down movement of the fixed block 10.

[0026] By adopting the above technical solution, it is possible to control the two fixed blocks 10 to move to opposite sides on the outer surface of the limit rod by starting the electric push rod in the feed assembly 12 until the fixed blocks 10 exit the grooves opened inside the connecting frame 8.

[0027] The working principle of the above embodiment is:

[0028] When in use, the small twenty-roll rolling mill-intermediate roller transverse movement mechanism device uses the displacement sensor 5 on one side of the mounting frame 1 to control the extension and retraction of the transverse movement cylinder 2, so that the transverse movement cylinder 2 drives the intermediate roller 4 to move transversely through the connecting piece 3. During inspection and maintenance, the electric push rod in the feed assembly 12 can be started to control the two fixed blocks 10 to move toward the opposite side on the outer surface of the limit rod until the fixed blocks 10 exit the grooves provided inside the connecting frame 8, thereby releasing the connection between the connecting frame 8 and the positioning frame 9, and then disassembling the intermediate roller 4 and the connecting piece 3, so as to facilitate the disassembly and inspection of the displacement sensor 5 and the transverse movement cylinder 2.
