Description

Technical Field

[0001] The utility model belongs to the technical field of iron and steel metallurgy, and in particular relates to a bulletproof device for disassembling and installing a protective cover of a fast rolling mill. Background Art

[0002] Now the contact surface between the bearing seat and the protective cover of the rolling mill is adjusted with the built-in spring. When the roll gap of the rolling mill is adjusted frequently, it is easy to cause the contact part of the built-in spring of the bearing seat and the protective cover of the rolling mill to pop out. When the matching size is exceeded, the stability of the rolling mill body will be reduced. In the production process, the protective cover is easy to pop out due to improper installation, delaying production and affecting the quality of rolled products. In the 750, 650, 450, 350, and 320 rolling mills, there is a spring under the protective cover to provide elastic force for the rolling mill to start pressing. The function is the same as that of the elastic damping body such as Suye rolling mill and Xihang rolling mill. When repairing the offline Zhonggang rolling mill, the protective cover is removed immediately after the pressing device is removed. Since there is still elastic force in the spring, when half of the screws are removed, the remaining bolts are not enough to tighten the protective cover. The spring elastic force can easily cause the protective cover and the remaining screws to fly, which is very easy to hurt people and poses a great safety hazard. In view of the above problems, in order to eliminate the safety hazards when removing the protective cover, we have designed a bulletproof device for rapid removal and installation of the rolling mill protective cover to solve this problem.
