Detailed description of the invention
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 2～Fig. 5, the utility model embodiment comprises the chamber body 1 of radiographic inspection chamber, the hermatic door body 2 of protective door, the guiding bleeder mechanism 3 at top, the load-bearing running gear 4 of bottom.
Hermatic door body 2 is obliquely installed, and has certain inclination angle, makes hermatic door body 2 and chamber body 1 clearance constant, operates steadily, and sealing is good; In the present embodiment, the angle of inclination of hermatic door body 2 is 5 degree, and sealing is better.Hermatic door body 2 comprises tiltler 5, top vertical body 6, bottom vertical body 7; Top vertical body 6 tilts to be fixed on the top of tiltler 5, forms the top of hermatic door body 2; Bottom vertical body 7 tilts to be fixed on the bottom of tiltler 5, forms the bottom of hermatic door body 2; Tiltler 5, top vertical body 6, bottom vertical body 7 are as a whole.Tiltler 5 is parallelogram, fits tightly with chamber body 1.Top vertical body 6 and bottom vertical body 7 are rectangle.Under hermatic door body 2 heeling conditions, top vertical body 6 and bottom vertical body 7 are in plumbness, and tiltler 5, in heeling condition, is so not only convenient to dividing potential drop and load-bearing, and have increased the sealing of hermatic door body 2.
Guiding bleeder mechanism 3 has guiding and dividing potential drop double action, and it comprises orbit 8 and guide wheel 9.Pre-buried chamber body 1 top that is fixed on of orbit 8, and arrange along the folding direction of hermatic door body 2.Guide wheel 9 is arranged on the side of top vertical body 6, and guide wheel 9 contacts with orbit 8 and moves along orbit 8, and this structure plays dual parts guiding and dividing potential drop.Guide wheel 9 has lateral forces to orbit 8.This guide wheel 9 not only play the guiding role, and also chamber body 1 is had to certain pressure-acting, can effective guarantee chamber body 1 and hermatic door body 2 between gap≤10mm.Guide wheel 9 is one, restraint of liberty degree, and dimension is unique.The lateral vertical on guide wheel 9 and hermatic door body 2 tops, the specifically lateral vertical of guide wheel 9 and top vertical body 6, dividing potential drop is effective.
Load-bearing running gear 4 comprises limit track 10, BOGEY WHEEL 12, Load-bearing rail 14, mount pad 13.Limit track 10 is fixed in bottom vertical body 7.Load-bearing rail 14 is fixed on chamber body 1 bottom.Mount pad 13 is fixed on Load-bearing rail 14.BOGEY WHEEL 12 is arranged on mount pad 13, and BOGEY WHEEL 12 contacts with limit track 10 and moves along limit track 10, and limit track 10 has limited the traffic direction of BOGEY WHEEL 12.Mount pad 13 is a kind of bilateral stopping means, can carry out BOGEY WHEEL 12 bilateral spacingly, prevents that BOGEY WHEEL 12 from departing from from Load-bearing rail 14.BOGEY WHEEL 12 is one, adopts single-wheel load-bearing, restraint of liberty degree, and dimension is unique.
Chain drive system 11 is connected with BOGEY WHEEL 12.Protective door is when chain drive system 11 drives operation, and omnibearing BOGEY WHEEL 12 spatial degrees of freedom that limited of mount pad 13 and limit track 10, operate steadily protective door.
