The roughing mill general assembly diagram adopting the protective cover structure is shown in fig. 6, a motor in a matching mode of a traditional protective cover and a wind shield is adopted, an axial distance of about 300mm is required to be reserved between the protective cover and a bearing seat or between the protective cover and a slip ring cover, and an installer talent has enough operation space for installing the joint surface of the protective cover.
Disclosure of Invention
The utility model aims to provide a motor protection cover and wind shield matching installation structure, which can shorten a motor shaft system and realize cost reduction and synergy of a motor; the protective cover is convenient to install: the cover can be smoothly installed without repeatedly disassembling and assembling the two half shields; and the potential safety hazard in the motor installation process can be reduced.
In order to achieve the above purpose, the technical scheme of the utility model is as follows: the motor protection cover and wind shielding ring matching installation structure comprises a protection cover and a wind shielding ring, wherein the shaft passing part of the protection cover is of a door type structure, the wind shielding ring consists of a left wind shielding ring and a right wind shielding ring, and joint surfaces between the left wind shielding ring and the right wind shielding ring are connected through rabbets on the left wind shielding ring and the right wind shielding ring by bolts and nuts; the installed wind guard ring is fixedly connected with the end face of the door-shaped structure at the position of the shield through shaft by bolts and nuts.
Furthermore, before the protective cover is installed, the left wind shielding ring and the right wind shielding ring are firstly arranged in a neutral position between the underframe and the lower end cover, and joint surfaces positioned below the rotating shaft are connected into a whole through bolts and nuts and then pushed to the bearing side.
Further, after the wind guard, the protective cover is directly arranged on the underframe in a falling way through the shaft, and two sides of the protective cover are fixed with the underframe through bolts.
Further, the protection casing is left and right two half symmetrical structure, and left and right two half junction and both ends have tip joint face respectively, and the top surface has top joint face.
The beneficial effects of the utility model are as follows:
1. the motor shafting can be shortened, and the cost reduction and synergy of the motor are realized;
2. the protective cover is convenient to install: the cover can be smoothly installed without repeatedly disassembling and assembling the two half shields;
3. the potential safety hazard in the motor installation process can be reduced.

Detailed Description
The utility model will be further described with reference to the drawings and examples.
As shown in fig. 7 to 11, the motor protection cover and wind deflector cooperation installation structure of the utility model comprises a protection cover 1 and a wind deflector 2. The over-shaft part of the protective cover 1 is a door-shaped structure 3, the wind shielding ring 2 is composed of a left wind shielding ring and a right wind shielding ring, and the joint surface between the left wind shielding ring and the right wind shielding ring is connected by a spigot 6 on the left half piece and the right half piece through bolts and nuts. The mounted wind guard ring 2 is fixedly connected with the end face of the door-shaped structure 3 at the position of the shield through shaft by bolts and nuts.
The protection cover 1 is of a left-right half symmetrical structure, the joint of the left half and the right half and the two ends are respectively provided with an end joint surface 4, and the top surface is provided with a top joint surface 5.
The installation method comprises the following steps: the two wind-shielding rings are installed before the protective cover is installed, the joint surface of the wind-shielding rings is installed at the neutral position between the underframe and the lower end cover, namely the joint surface below the rotating shaft, the joint surfaces of the wind-shielding rings are connected by the joint surfaces of the left and right halves and are connected by bolts and nuts, the wind-shielding rings are not required to be fixed on any other parts, after the wind-shielding rings are installed, the wind-shielding rings are placed in place at the neutral position between the underframe and the lower end cover and then pushed to the bearing side, at the moment, the protective cover is installed, because the shaft-passing position of the protective cover with a new structure is a door type, the two halves are not required to be disassembled, the shaft-passing can be directly carried out, the whole protective cover falls down together, after the protective cover is in place, the two sides of the protective cover are screwed with the fixing bolts of the underframe, thus the labor and the tooling cost for dismounting the protective cover can be saved, the limit of the operation space is greatly improved, the installation problem of the joint surface of the protective cover and the shaft-passing position of the wind-shielding rings is solved, the whole shaft system can be shortened by about 200 mm, the whole shaft system can be shortened by 400mm, the materials of the rotating shaft and the underframe can be roughly reduced by 10 yuan, and 10 rolling units can be realized.
