The invention discloses a method and device for carrying out X-
ray transillumination by utilizing a GIS
barrel body as support. According to the method, a mechanical lifting device is arranged on the GIS
barrel body to carry out the X-
ray transillumination. The device comprises the GIS
barrel body (10), the two faces, right opposite to each other, located on the upper portion of the GIS barrel body (10) are provided with hoisting pulleys (5) which are provided with hoisting ropes (3), the two ends of each hoisting
rope (3) wind around the hoisting pulleys (5) and are connected with a hand-
crank capstan (2) located on the lower portion of the GIS barrel body (10), the hoisting
rope located on one face of the GIS barrel body (10) is provided with a DR plate assembling hanging frame (4), and the hoisting
rope (3) located on the other face of the GIS barrel body (10) is provided with an X-
ray machine hanging mechanism (8). The method and device can effectively solve the problems that in the prior art, when X-ray detecting is carried out on a GIS, the method of lifting and fixing an X-ray
machine and a DR plate is unpractical,
transillumination is inconvenient, the occupied space is large and the field space cannot meet the demands easily.
