Abstract
The utility model relates to an automatic protective shield door device that is used for radiation imaging inspection system, belonging to the technical field of radiation protection. The device which comprises a door panel, two slides at each side, racks, gears and an electric motor, is characterized in that the two slides is fixed on the upper plane of the frame and is connected with the door panel with bearing in a sliding way; the racks, fixed on the bottom part of the door panel, engage with the gears which are connected with the motor shaft fixed on the lower part of the frame. The utility model can realize automatic and complete shied protection with no interference to the radiation imaging inspection system, thereby achieving intelligent control and avoid accidental radiation leakage.
Description
Technical field
The utility model belongs to the radiation protection technique field, particularly relates to a kind of automatic protection door apparatus that is applied to radiation imaging check system.
Background technology
In the prior art, the protector that is applied to the access, detection sensitive volume of radiation detection system is generally rubber curtain that accompanies lead layer etc.Because they are passive types, so can affect to wanting inspected object to pass in and out detection system detection sensitive volume smoothly; It is totally enclosed to adopt this form not make, and can have certain radiation leakage, and the protective shielding effect is undesirable.Simultaneously, owing to be subjected to the restriction of this body structure, can only be applied to vertical direction.
Summary of the invention
At above-mentioned problems of the prior art, the purpose of this utility model provides a kind of automatic protection door apparatus that is used for radiation imaging check system, and it can realize automatic, the complete and glitch-free shielding protection to radiation detection system.
To achieve these goals, the utility model is achieved through the following technical solutions:
The automatic protection door apparatus that is used for radiation imaging check system, it comprises door-plate, two wood side-guides, tooth bar, gear and motor.Its design feature is that described two wood side-guides are fixed on the last plane of framework and are slidingly connected with bearing and door-plate.The bottom stationary rack of door-plate and and gears engaged.The motor shaft of gear below being fixed on framework is connected.
According to above-mentioned technical scheme, the lower plane rear and front end of described framework is provided with plays closing the door near switch and opening the door near switch of limit protection effect to door-plate.
According to above-mentioned technical scheme, the rear and front end, last plane of described framework is provided with the rubber link stopper to the effect of door-plate start stop bit.
According to above-mentioned technical scheme, described door-plate is to be made by metal material with radiation proof function or the additional metal material screen layer with radiation proof function of common metal material.
According to above-mentioned technical scheme, described metal material screen layer is a metal.
The utility model has adopted technique scheme, has following beneficial effect:
1) owing to adopted single fan integral protection shield door, therefore can realize fully closed protection fully.
Therefore 2), can the detection sensitive volume that object passes in and out radiation detection system not had any impact because the protective shielding door is by the electrical equipment Based Intelligent Control.
3), can guarantee that radiation detection system can just not begin to detect before the protective shielding door shuts, thereby can avoid unexpected radiation leakage owing to the stopping means that has adopted door-plate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the vertical view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
Referring to Fig. 1～Fig. 3, the utility model comprises door-plate 1, two wood side-guides 2, tooth bar 3, gear 4 and motor 5.Door-plate 1 is to make by the metal material with radiation proof function or by the additional metal material screen layer 8 with radiation proof function of common metal material.Metal material screen layer 8 is a metal.Two wood side-guides 2 are fixed on the last plane of framework 6 and are slidingly connected with bearing 7 and door-plate 1.The bottom stationary rack 3 of door-plate 1 and with gear 4 engagement.The motor 5 spool of gear 4 below being fixed on framework 6 is connected.The lower plane rear and front end of framework 6 is provided with closing the door near switch 9 and open the door near switch 10 1 on door-plate limit position-limiting action.The rear and front end, last plane of framework 6 is provided with the rubber link stopper 11 to door-plate 1 start stop bit effect.
When using the utility model, utilize framework 6 to be installed in the position of shielding it.The keying of motor 5 control door-plates 1.Rubber link stopper 11, close the door near switch 9 and open the door and can be respectively transmit signal near switch 10 and form and utilize the Based Intelligent Control of electrical equipment, avoid the generation of accidental exposure leakage situation door-plate 1 to control system.
