Quick release cushioned T.V. camera mount
First Claim
1. A mounting system for a television camera for use with a refueling machine having a gripper assembly, to facilitate the guidance of the gripper assembly relative to fuel assemblies of a nuclear reactor core comprising:
- a vertically movable mast;
gripper means mounted on said movable mast;
actuator means disposed within said mast for actuating said gripper means;
a television camera, disposed in a housing, coaxially mounted within said mast by means of a shock absorbing system, whereby said television camera is isolated from both vertically upwardly and vertically downwardly directed shock loads;
said shock absorbing system having first spring-biased means normally biased vertically downwardly, and second spring-biased means normally biased vertically upwardly, with said television camera interposed between said first and second spring-biased means; and
a pair of semi-circular support rings disposed around said housing between said first and second spring-biased means, said support rings having an arcuate extent less than 180° and
defining diametrically-opposed, radially extending slots therebetween, said camera housing having a pair of diametrically-opposed, outwardly extending lugs thereon and each of said semi-circular support rings having a recess on the upper portion thereof, whereby said lugs can be aligned with said slots, permitting upward axial movement of said camera housing, so that said lugs can clear said support rings, and said camera housing can be rotated to dispose said lugs within said recesses and lock said camera housing in place.

Abstract
A refueling machine within a nuclear reactor facility includes an inner mast or gripper tube (12) to the bottom of which is secured a gripper assembly (16). An actuator tube (20) controls the gripper mechanisms of the gripper assembly (16), and in order to insure proper and accurate alignment of the gripper mechanisms with the fuel assembly nozzles, a television camera (26) is mounted within the actuator tube (20). A television monitor (34) is operatively connected to the television camera (26), the monitor (34) being disposed upon the refueling machine personnel trolley. The television camera (26) is removably mounted within the actuator tube (20) by a bayonet-type system which includes camera housing lugs (78) which are adapted to pass through slots (76), subsequent to which the camera housing (28) and the lugs (78) are rotated 90° whereby the lugs (78) are seated within recesses (80). The mounting system further includes shock absorbing spring systems (52, 62) for isolating the camera (26 ) for vertically upwardly and vertically downwardly directed shock loads.
