Appliance for clamping rod-like part during maintenance of nuclear power plant

Abstract

The invention discloses an appliance for clamping a rod-like part during maintenance of a nuclear power plant. The appliance comprises a connector, wherein the connector is connected with a stretching mechanism; the stretching mechanism is connected with a clamping piece; the clamping piece comprises two clamping plates; one end of each clamping plate is connected with the stretching mechanism; when the stretching mechanism stretches, the clamping plates move in the direction of a central line between the two clamping plates; and the ends, far away from the stretching mechanism, of the clamping plates are bent to be 90 degrees in the direction of the central line between the two clamping plates, the end surfaces sink inwards to form arc-shaped grooves, and the arc-shaped grooves completely penetrate the end surfaces. The appliance is simple in structure and convenient to use, and can realize accurate and stable grabbing of the rod-like part, direct contact between a human body and the rod-like part on which radiation remains is reduced, and the safety of the human body is protected.

Description

technical field [0001] The invention relates to nuclear power assembly equipment, in particular to an apparatus for clamping rod-shaped components during maintenance of nuclear power plants. Background technique [0002] A nuclear power plant is a power plant that uses the energy released by nuclear fission or fusion reactions to generate electricity. Nuclear power plants currently in commercial operation use nuclear fission reactions to generate electricity. Nuclear power plants are generally divided into two parts: a nuclear island that uses nuclear fission to produce steam (including reactor devices and primary loop systems) and a conventional island that uses steam to generate electricity (including a turbogenerator system). The fuel used is generally radioactive heavy metals: uranium, plutonium. Nuclear power plants use nuclear reactors instead of boilers in thermal power plants, and use nuclear fuel to generate heat in a special form of "combustion" in nuclear reacto...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that it is inconvenient to grab the rod-shaped parts during maintenance in existing nuclear power plants, and the residual radiation is harmful to the human body. The device can achieve accurate and stable grasping of rod-shaped parts, reducing direct contact with the human body, thereby protecting the safety of the human body
