Problems solved by technology

However, since the photographic inspection uses high-energy rays above 9 MeV, it is more harmful to human health. According to the safety operation regulations for workers in the radiation environment, the operator must wait for half an hour after each photograph is completed before entering the radiation work. area, so the efficiency of photographic inspection is very low

Embodiment Construction

[0014] Referring to the accompanying drawings, the present invention includes a frame 3 , a bracket 9 and a base 1 connected to the frame 3 . The base 1 is provided with a film box capable of airtightly storing films, which is composed of a housing 2 connected to the upper plane of the base 1 and a movable film holder 13 that can be airtightly buckled with the housing 2 . A plurality of sheets of film 14 can be placed vertically evenly on the moving film holder 13, and the bottom of the moving film holder 13 is connected with a rotary mechanism 15 that can make it rotate. The slewing mechanism 15 is a rotating width structure formed by an external gear and an internal ring gear driven by a motor. The bottom of the slewing mechanism 15 is connected with the push-pull mechanism one 16 which is horizontally fixed in the base 1 . Push-pull mechanism one 16 is made up of motor and spiral width, and motor and the screw mandrel that is connected with motor output shaft are fixed in ...

Abstract

This invention relates to a high energy x-ray photo taken device for changing films automatically. A film box is set on the base closely storing films composed of a shell connected with the plane on the base and a moving film frame closely locked with the shell. Multiple films are vertically and uniformly distributed on the frame, bottom of the frame is connected with a slewing gear driving the frame rotate, bottom of the slewing gear is connected with a drag gear horizontally fixed at the base. Said bracket is scarfly jointed on the middle of the frame by the horizontal slideway above the film box, claws with lifting structure are lifted vertically mounted on the bracket capturing films, a lifting unit and a pull unit are set between the bracket and the frame driving the bracket move vertically and horizontally.

Description

technical field [0001] The invention relates to the technical field of non-destructive radiation detection, in particular to an automatic film changing device for high-energy ray X-ray photography. Background technique [0002] When using high-energy radiography to inspect products, the method of X-ray film radiographic inspection is usually used. In the prior art, every time a piece of film is photographed, the staff must enter the testing site to replace the film for the next photographing. However, since the photographic inspection uses high-energy rays above 9 MeV, it is more harmful to human health. According to the safety operation regulations for workers in the radiation environment, the operator must wait for half an hour after each photograph is completed before entering the radiation work. area, so the efficiency of photographic inspection is very low. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the obje...
