Beschreibung
Zusammenfassung:	The invention belongs to the field of nuclear station radiation protection, and specifically discloses a ray shielding device for heavy water reactor power station reactor end face maintenance. The device comprises a trolley, a Z-axis track beam, an electro-hydraulic system, and a shielding chamber. The electro-hydraulic system is arranged above the shielding chamber, the Z-axis track beam is arranged above the electro-hydraulic system, and the trolley is arranged above the Z-axis track beam. The device has enough space where two people can work with tools, the shielding chamber takes lead as the shielding material, the comprehensive shielding efficiency can reach 80%, and the shielding room is capable of providing whole-body shielding protection for the staffs working in the shielding room.
