Abstract
A device for the placement of rod shaped fuel elements and control bars especially in a nuclear reactor, in which a gripper body is adapted for being connected to gripper tools and which gripper tools are engageable with the elements to be placed. The gripper tools are carried in a frame and are moveable in the frame laterally to the axis of the gripper body so as to selectively be engageable therewith. A single power operated device in the gripper body is provided for actuating the gripper elements carried by the gripping tools.
Claims39
A gripping device especially for use in connection with the placement of fuel elements and control bars of a reactor core;
- a tubular member, a gripper body moveable axially in said member, gripper tools adapted for being coupled to the lower end of said gripper body, a single power operable device in said gripper body for actuating said gripper tools, said gripper tools having like upper and lower guiding means, said upper guiding means being engageable by the lower ends of said gripper body, said lower guiding means being engageable with elements to be placed, said upper guiding means telescopically engaging the lower end of said gripper body, abutment means limiting said telescopic engagement, and connecting means substantially positively connecting the gripper body to a gripper tool in telescopic engagement therewith.
A gripping device especially for use in connection with the placement of fuel elements and control bars of a reactor core;
- a tubular member, a gripper body moveable axially in said member, gripper tools adapted for being coupled to the lower end of said gripper body, a single power operable device in said gripper body for actuating said gripper tools, said single power operable device being a fluid motor in said gripper body, spring means acting on the fluid motor in a direction to cause closing of said gripper tools, remotely controlled means for actuating said motor in tool opening direction, said gripper tool having an adjustable body therein, said fluid motor including an element engageable with said adjustable body, and connector means for connecting said element to said adjustable body.
a. A gripping device for use in connection with the placement of longitudinal bodies, especially of fuel elements and control bars of a reactor core, comprising:
- b. a tubular member,
- c. a gripper body movable axially in said member,
- d. at least two various gripper tools each of which is determined for another group of longitudinal bodies and has upper guiding means,
- e. the upper guiding means of all gripper tools being adapted to the same guiding means at the lower end of the gripper body,
- f. in such a manner that selectively only one of said gripper tools may be attached to the gripper body in its operational position and coupled to the gripper body by connector means,
- g. said gripper body containing a power operable device for actuating any one gripper tool which will be coupled to the gripper body.
