[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1-Figure 2The utility model provides a rotating device for a rolling mill arch, wherein the side wall of the rolling mill arch is provided with a protrusion; the device comprises: a bracket 1; the bracket 1 comprises a bottom plate 11, a side plate 12 and a supporting rib 13; the side plates 12 are arranged on both sides of the bottom plate 11 along the vertical direction, the supporting rib 13 is vertically arranged between the side plates 12 and the bottom plate 11, and the side plates 12 are inclined toward the left and right sides of the bottom plate 11; the driving motor 2 is symmetrically arranged on the left and right sides of the rotating device; the rotating shaft 3 passes through the side plate 12, one end of which is connected to the output shaft of the driving motor 2, and the other end is connected to a fixed connecting plate 31; the fixing bolt 4 is provided at the top end of the side plate 12 and is detachably connected to the protrusion. In addition, a fixing groove 311 is provided on the side wall of the fixed connecting plate 31; the fixing groove 311 is used to fix the fixing blocks provided on the left and right sides of the rotating device.

[0030] Reference Figure 1 , the fixing bolts 4 are inserted into the protruding parts of the side walls of the mill arch, and the fixing blocks on the left and right sides of the mill arch are inserted into the fixing grooves 311 on the fixed connecting plate 31; thereby, the fixation of both sides of the mill arch is completed at the same time; at this time, when it is necessary to repair and assemble the mill arch in the horizontal direction, the driving motor 2 is controlled to rotate so that the fixed mill arch is rotated to a horizontal position to complete the repair and assembly of the mill arch; and when it is necessary to repair and assemble the mill arch in the vertical direction, the driving motor 2 is controlled to rotate again so that the mill arch is rotated to the vertical direction to facilitate the maintenance and assembly of the operator.

[0031] The top end of the side plate 12 is rotatably connected to the limit plate 121 through a rotating pin; after the limit plate 121 is rotated, it is used to block the front and rear sides of the rolling mill arch.

[0032] Reference Figure 2 When the mill arch is rotated into a vertical state for maintenance and assembly, the limit plate 121 of the mill arch is rotated and lowered to press against the front and rear sides of the mill arch to prevent the mill arch from shaking and improve the fixing effect of the mill arch.

[0033] The fixing bolts 4 are inclined toward the outside of the side plate 12 .

[0034] Reference Figure 1 In order to improve the fixing effect of the fixing bolts 4 on the protruding part of the side wall of the rolling mill arch, the fixing bolts 4 are inserted obliquely into the top of the side plate 12 and fixedly connected by welding; therefore, when the rolling mill arch rotates, the obliquely arranged fixing bolts 4 can increase the supporting force in both vertical and horizontal directions, thereby strengthening the fixing effect of the rolling mill arch.

[0035] The fixing groove 311 is configured to be in an inverted L-shape; the shape of the fixing block matches the shape of the fixing groove 311 .

[0036] Reference Figure 1When the fixing block is inserted into the fixing groove 311, the inverted L-shaped shape of the fixing groove 311 can provide vertical support force for the fixing block on the side wall of the rolling mill arch, thereby improving the fixing effect of the rolling mill arch.

[0037] Working principle:

[0038] First, insert the fixing bolts 4 on both sides of the rotating device into the protrusions of the side wall of the rolling mill arch, and insert the fixing blocks on the left and right sides of the rolling mill arch into the fixing grooves 311 on the fixed connecting plate 31; thereby, the fixing of both sides of the rolling mill arch is completed at the same time.

[0039] Therefore, when the rolling mill arch needs to be repaired and assembled in the horizontal direction, the driving motor 2 is controlled to rotate so as to rotate the fixed rolling mill arch to a horizontal position, thereby completing the repair and assembly of the rolling mill arch.

[0040] When the mill arch needs to be repaired and assembled in the vertical direction, the driving motor 2 is controlled to rotate again so that the mill arch is rotated to the vertical direction, which is convenient for the operator to repair and assemble.

[0041] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
