[0002] Ring rolling machine is also called ring expander or hole expander, which is a processing equipment for plastic deformation of ring piece, such as wall thickness reduction, diameter expansion and cross section profile forming, and is widely used in the fields of machinery, automobile and aerospace. The commonly used ring rolling machine comprises a main roller, a core roller, a material supporting plate and a taper roller. The right side of the ring rolling machine is provided with the main roller, and the left side of the ring rolling machine is provided with the taper roller. The core roller and the material supporting plate are arranged between the main roller and the taper roller. The main roller, the core roller and the taper roller are in contact with the outer wall, the inner wall and the end wall of the ring blank respectively. When the ring rolling operation is performed, the ring blank is placed on the material supporting plate, the core roller passes through the ring blank, and the taper roller is close to the ring blank. The ring rolling machine is started, and the ring blank starts to rotate under the driving of the main roller and the core roller. The upper and lower taper rollers press on the two end surfaces of the blank at the same time, and the main roller rolls the ring blank from one side.
[0003] Due to the large tonnage of the ring rolling machine, part of the equipment is installed below the ground structure to reduce the operation height of the equipment. Therefore, a pit is arranged at the working position of the ring rolling machine, and each movement mechanism of the ring rolling machine moves on the pit. In order to prevent the falling of workers or articles, a handrail needs to be arranged around the pit, and an entrance and exit for workers is reserved. In addition, a protective net needs to be arranged on the upper surface of the pit. For the protective net on the upper surface of the pit, due to the long moving distance of each movement mechanism at the working position of the ring rolling machine, the fixedness of the closing and opening positions of the movements between each mechanism, and the high temperature working environment at the working position, it is difficult to use the conventional method to safely protect the pit at the working position.
