Sealed steel wire rope drive system

Abstract

The invention discloses a sealed steel wire rope drive system. The system comprises a wall penetrating pipe assembly and a steel wire rope assembly, wherein the wall penetrating pipe assembly penetrates through a wall body; the steel wire rope assembly penetrates through the wall penetrating pipe assembly, and comprises an indoor steel wire rope (8), an outdoor steel wire rope (16) and a connecting shaft (11); the indoor steel wire rope (8) is connected and fixed to a first end of the connecting shaft (11); the outdoor steel wire rope (16) is connected and fixed to a second end of the connecting shaft (11); a corrugated pipe (9) is sleeved on the connecting shaft (11); a first end of the corrugated pipe (9) is fixed on the wall penetrating pipe assembly in a sealed mode; and a second end of the corrugated pipe (9) is fixed on a second end of the connecting shaft (11) in a sealed mode. According to the invention, during the process of axial moving of the connecting shaft, the corrugated pipe stretches along with the moving of the connecting shaft, so that the problem that radioactive harmful gases such as Alpha aerosols leak through a clearance between the connecting shaft and the wall penetrating pipe assembly is solved, and the safety of operators is ensured.

Description

technical field [0001] The invention relates to a sealing system, in particular to a steel wire rope sealing transmission system, which is suitable for the transmission seal between the active mechanical arm and the driven mechanical arm in the hot cell manipulator. Background technique [0002] The hot cell is a shielded small room for high radioactive experiments and operations. The outer wall is a heavy concrete structure to prevent the radioactive substances in the hot cell from affecting the physical and mental health of outdoor operators. The front wall of the hot cell is generally equipped with a peep window of lead glass or high-density liquid, and the manipulator is used for remote operation, that is, the movement of the active mechanical arm outside the hot cell is transmitted to the driven machine in the hot cell through the steel wire rope in the wall tube. The arm enables remote operation inside the thermal chamber. [0003] The wall-piercing pipe is usually in...
