[0023] according to Figure 1-5 As shown: the utility model provides a high-stability hot rolling mill that is easy to adjust: it includes a base 1; two fixed columns 2 are fixedly arranged on the base 1, and a slide groove 3 is opened in the fixed column 2, and a sliding column 4 is slidably arranged in the slide groove 3; the sliding column 4 is fixedly connected to a support plate 6 upward, and a support frame 5 is fixedly arranged below the support plate 6, and an upper hot rolling roller structure 7 is arranged in the support frame 5; a motor 17 is arranged in the base 1, and a screw rod 15 is fixedly connected to the output shaft of the motor 17; a lifting plate 14 is threadedly connected to the screw rod 15, and the lifting plate 14 can drive the sliding column 4 to slide synchronously; a wheel body frame 18 is fixedly arranged below the lifting plate 14, the wheel body frame 18 passes through the base 1, and a roller 16 is arranged in the wheel body frame 18.

[0024] By setting the motor 17 and the screw rod 15 structure, the roller body spacing can be adjusted stably and conveniently, and the roller body lifting structure can drive the roller 16 to rise and fall, which facilitates the movement of the hot rolling mill and ensures the working stability of the hot rolling mill.

[0025] Two corresponding mounting plates 9 are fixedly arranged on the two fixing columns 2, and a lower hot rolling roller structure 8 is arranged between the two mounting plates 9. The upper hot rolling roller structure 7 and the lower hot rolling roller structure 8 both include a power device 10, and a rotating shaft 11 is fixedly connected to the output shaft of the power device 10, and the hot rolling roller body is fixedly connected to the rotating shaft 11; the power device 10 of the upper hot rolling roller structure 7 is fixedly arranged in the support frame 5, and the power device 10 of the lower hot rolling roller structure 8 is fixedly arranged on the mounting plate 9.

[0026] When adjusting the distance between the upper and lower hot rolling rollers, the lower hot rolling roller structure 8 is kept stationary, and only the upper hot rolling roller structure 7 needs to be adjusted.

[0027] A connecting groove 12 communicating with the slide groove 3 is provided in the base 1 , and the sliding column 4 extends downward into the connecting groove 12 ; a connecting rod 13 is fixedly connected to the lifting plate 14 , and the connecting rod 13 is fixedly connected to the sliding column 4 .

[0028] The arrangement of the connecting groove 12 and the sliding column 4 can limit the rotation of the lifting plate 14 , thereby converting the rotation of the screw rod 15 into the movement of the lifting plate 14 , and then driving the sliding column 4 to slide up and down through the connecting rod 13 .

[0029] A fixed block 21 is fixedly connected to the bottom of the base 1, and a sliding block 19 is slidably arranged in the fixed block 21; a support leg 20 is fixedly connected below the sliding block 19, a bolt hole 22 is provided on the sliding block 19, and the fixed block 21 and the sliding block 19 are fixedly connected by a fixing bolt 23.

[0030] The setting of the sliding block 19 facilitates changing the height of the supporting leg 20. When the roller 16 is used to move the hot rolling mill, the supporting leg 20 is raised to prevent the friction between the supporting leg 20 and the ground from affecting the movement of the hot rolling mill; the setting of the two bolt holes 22 facilitates the connection and fixation of the sliding block 19 and the fixed block 21; the height of the supporting leg 20 is lower than the height of the roller 16 to ensure that the supporting leg 20 is in contact with the ground, thereby ensuring the stability of the hot rolling mill during operation.

[0031] Principle of the utility model

[0032] When the height of the hot rolling roller needs to be adjusted, the motor 17 is directly started to make the sliding column 4 slide up and down driven by the lifting plate 14 and the connecting rod 13; the position of the lower hot rolling roller structure 8 remains fixed, and the height of the upper hot rolling roller structure 7 rises and falls with the rise and fall of the height of the sliding column 4 and the support plate 6, so the distance between the upper and lower hot rolling rollers can be adjusted; therefore, it is very convenient to use the motor 17 to adjust the distance between the upper and lower hot rolling rollers, which greatly saves manpower; at the same time, the threaded connection structure of the motor 17 screw rod 15 is self-locking, and the stability of the upper hot rolling roller structure 7 can be guaranteed after the adjustment is completed.

[0033] When the hot rolling mill is operating normally, Figure 4 The state shown, that is, the support leg 20 is in contact with the ground, and the roller 16 is suspended, can ensure the stability of the entire hot rolling mill. When the hot rolling mill needs to be moved, the upper and lower hot rolling rollers will no longer work; first start the motor 17 to move the lifting plate 14 downward until the roller 16 in the wheel frame 18 is flush with the support leg 20; at this time, the roller 16 is also in contact with the ground, remove the fixing bolt 23, retract the sliding block 19 into the fixing block 21, and then use the fixing bolt 23 to re-fix the sliding block 19; at this time, the height of the support leg 20 is higher than the height of the wheel body, to prevent the support leg 20 from rubbing against the ground when the wheel body is in use and affecting the normal operation of the hot rolling mill. When the hot rolling mill moves to the specified position, first put down the sliding block 19 and the support leg 20 so that the support leg 20 is in contact with the ground; reverse the motor 17 to drive the roller 16 to move upward so that the roller 16 is off the ground, and the support leg 20 is completely in contact with the ground.

[0034] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
