Remote replacement device for O-shaped ring

Abstract

The invention discloses a remote replacement device for an O-shaped ring. The remote replacement device for the O-shaped ring comprises an O-shaped ring supporting mechanism and a lever mechanism used for controlling the O-shaped ring to ascend and descend. The supporting mechanism comprises a base and a supporting base, wherein the base and the supporting base are connected through a connecting rod. A center shaft is arranged between the base and the supporting base. The upper end of the center shaft penetrates through the supporting base to be connected with a rotary disk. A plurality of connecting rods are connected to the rotary disk in the circumferential direction. The sliding rods are connected with sliding shafts. The sliding shafts can slide in long straight grooves formed in the supporting base. The upper portions of the sliding shafts are connected with supporting rings. A bearing ring is arranged outside the supporting rings. The bearing ring is connected with the level mechanism. By the adoption of the remote replacement device for the O-shaped ring, the O-shaped ring can be replaced under the condition of remote operation. The remote replacement device for the O-shaped ring is particularly suitable for a radioactive environment or a toxic environment. Operators can be prevented from touching a radioactive medium or a toxic medium, the danger coefficient of an operator is greatly reduced, and the replacement safety is improved.

Description

technical field [0001] The invention relates to the technical field of O-ring replacement, in particular to a device capable of realizing long-distance replacement of the O-ring, which can increase the diameter of the O-ring and install it in a mounting groove of the O-ring. Background technique [0002] The present invention is proposed for the radioactive or toxic environment, and is an O-ring device used in the radioactive or toxic environment. like figure 1 As shown, the O-ring is installed in the sealing groove B of the flange, at the position indicated by A in the left figure, and the enlarged view of the position indicated by A in the right figure. When the seal ring needs to be replaced, it cannot be replaced by hand. For direct replacement, it is necessary to clean and decontaminate the environment in which the equipment is located to reach the level of pollution acceptable to personnel, and then replace it directly by hand. This replacement method not only reduces...
