Abstract

The invention provides a pincer device which can be used in water narrow space of radiation environment of a nuclear power station. The extraction force of the pincer device is larger than 2000 N. Thepincer device comprises a pincer mechanism, a first hydraulic cylinder, a cylinder body, a hose, a winding wheel, a pressure sensor, a second hydraulic cylinder and a control system. The control system provides power for the pincer mechanism. The first hydraulic cylinder synchronous with the second hydraulic cylinder achieves opening and closing while driving the pincer mechanism to do reciprocating linear motion. Due to multi-directionality of force vector for workpiece extracting of pincers and workpiece clamping of clamping toes, the pincer mechanism has good stability at the stroke limitposition of the clamping toes. By means of the design of the geometrical shape of the clamping toes, the bearing face can be enlarged, it is ensured that the clamping toes do not deform, and the clamping stability and safety are improved. The pincer device is a long-distance tail end execution mechanism, developed by integrating the characteristics of high radiation, narrow space, high flexibilityand capability of operating in water, of an irradiation-resistant robot and a mechanical arm.

Description

technical field [0001] The invention relates to a non-standard clamp device for extracting workpieces in a narrow space in water of a nuclear power plant, in particular to a device for realizing safe clamping and extraction of parts with the help of sensors. It is a clamping device suitable for working in a radioactive environment, which can firmly clamp and extract parts that cannot be entered by people and shielded in the container. It can be used as a remote control end effector for radiation-resistant robots and mechanical arms. Background technique [0002] The first consideration in the operation and maintenance of nuclear power plants is to reduce the impact of radioactive substances on the environment, and to provide workers on site with optimal working conditions for radiation protection. At the same time, the use environment of the clamp device, the size of the operating space, and the firmness and safety of the clamp should be considered. The clamping devices wi...
