Introduction

The remote operation device of radioactive materials plays a key role in the fields of nuclear energy and nuclear technology, and has a profound impact on the safe operation and environmental protection of the nuclear industry.

Its core function is to perform maintenance, dismantling, and operation tasks in a high-radiation environment, effectively isolating operators from radioactive materials.

This type of device not only ensures the safety and health of workers, but also improves work efficiency and reduces it reduces production and operation costs and is an important tool that is indispensable for the safe and efficient operation of the nuclear industry.

GB/T 45523 "Remote Operation Device for Radioactive Materials" focuses on mechanical master-slave manipulators, electric follow-up master-slave manipulators, power machinery these types of manipulators meet various needs with their respective control flexibility, load capacity and applicable scenarios.

The scientific and reasonable selection, deployment and continuous maintenance of these remote operation devices can effectively reduce the operator's Radiation exposure level, effectively control production and operation costs, and improve operating efficiency and overall system safety. This is not only a technological advancement it is an important contribution to human health, environmental protection and sustainable development. Therefore, we continue to optimize the design of the device and improve the automation level.

The key to promoting the sustainable development of remote operation technology of radioactive materials is to strengthen personnel training and management.

GB/T 45523 "Remote Operation Devices for Radioactive Materials" is planned to consist of five parts.

3 Terms and definitions

The terms and definitions defined in GB/T 45523.1 and GB/T 45523.2 and the following apply to this document.

leak-tight connector an intermediate device installed between the clamp and the straight bar.

Note. Used to maintain the continuity of the seal and transmit the clamping movement in the sealed state.

4 Structure and function

4.1 The sword-shaped manipulator is mainly composed of an end effector, a tubular straight rod and a handle. The transmission element in the straight rod realizes the connection between the end effector and the handle.

The sword-type manipulator is usually installed on a shielded wall or a sealed box, or it can be installed on a carrier or operated directly by an operator.

Take over and hold.

4.2 The sword-type manipulator can directly transmit the operator's actions from the handle to the end effector. The sword-type manipulator is installed on a shielded wall or a closed when sealing the box, a protective cover assembly can be installed to ensure the airtightness of the box and prevent contamination of the robot.

4.3 Depending on the intended use, a removable or non-removable end effector may be used.

The manipulator is divided into horizontal sword-type manipulator and vertical sword-type manipulator. The vertical sword-type manipulator has a longer straight rod and a larger diameter.

According to the different structures, both horizontal sword-type manipulators and vertical sword-type manipulators can be divided into three types. rigid straight-rod type, joint straight-rod type and wrist joint type.

4.4 The horizontal sword manipulator has a moderate load capacity. The horizontal sword manipulator is generally used in environments with small operating spaces to perform a
