Abstract
The invention relates to a box door closure detection system for an irradiation box. The system includes the following parts: an irradiation box door body, a box body, a box door locking device and a detection part. The box door locking device includes door fixing blocks, a connecting rod, connecting plates, bolts, frame fixing blocks. The detection device is installed at a maze corridor entrance of an irradiation chamber. Firstly, the heights of the parts of the closed bolts, exposed at the upper end of the box body of the irradiation box are detected and secondly, the width of the gap between the irradiation box door body and the box body is detected. The detection device can selectively adopt a sensor such as an optical fiber, a photoelectric switch, a proximity switch and a travel switch and the like. The irradiation box is produced in mass and has a limited dimension error. After the irradiation box door is latched, the heights of the parts of the connecting rod, exposed outside the irradiation box, have an identical value. If the height of the connecting rod is larger than a designed height or the gap between the box door body and the box body is larger than a width during normal closure, it shows that the box door is not closed normally and then the detection device sends an alarm, and then source reduction and operation stop of a transmission link are performed so that it is convenient for users to perform debugging timely and prevent happening of serious accidents.
Description
Technical field
The present invention relates to irradiation safety monitoring technology, especially irradiation box chamber door occlusion detection system.
Background technology
The gamma rays (gamma-rays) that 60Coradiation source produces, because its penetration capacity is strong, food that directly processing and packing is good, medicine, medical equipment etc., carry out irradiation to processed article, to make it, as sterilization, material modification, biomutation etc.But due to the singularity of nuclear matter, probably cause nuclear pollution if go wrong, to local society, public security is brought and is had a strong impact on, therefore countries in the world are all quite paid attention to its safe operation, irradiation box specification in prior art, chamber door open-and-close mode disunity, also there is aborning Co 60 radioactive source in RADIATION PROCESSING process, with the goods scratching of being equipped with in irradiation box or the irradiation box of goods, make to produce and cannot normally move and radioactive source is blocked the accident that can not return to safely down-hole and occurs, overhaul owing to manually cannot entering radiation chamber, goods is shone initiation fire for a long time, bring about great losses, even cause Radiation Center to be scrapped.For preventing above-mentioned condition, the invention provides a kind of irradiation box safety monitoring system, before making irradiation box enter radiation chamber, can carry out automatic safe inspection, if occur, irradiation chamber door is not closed tight, irradiation chamber door is closed tight but automatically out of service while thering is no the situations such as locked, the goods of machinery expenditure irradiation box outline, radiation chamber internal source is fallen in water automatically, and Realtime Alerts.
Summary of the invention
Irradiation box chamber door occlusion detection system comprises irradiation chamber door body, casing, chamber door blocking device and several parts of pick-up unit.Wherein chamber door blocking device is made up of door fixed block, connecting rod, web joint, latch, frame fixed block, offside at irradiation chamber door body door-hinge respectively arranges a fixed block up and down, interior expense hole, irradiation box casing correspondence position arranges connecting rod, a latch is respectively established by web joint in the upper and lower two ends of connecting rod, connecting rod is fixedly connected with irradiation casing by the frame fixed block with pin-and-hole being positioned on irradiation casing, and connecting rod can be moved up and down along frame fixed block pin-and-hole, and frame fixed block can prevent that connecting rod from rotating in pin-and-hole; Latch for and the pin-and-hole of door on fixed block coordinate, realize the closure of chamber door, the latch that moves up separates with door fixed block, a door body can be opened, and moves down latch and inserts the pin-and-hole on door fixed block, door locking.Pick-up unit is arranged on porch, radiation chamber fan road, and the one, detect closed latch and be exposed at the height of irradiation box casing upper end; The 2nd, detect irradiation chamber door body and casing gap width, pick-up unit can be selected the sensors such as optical fiber, optoelectronic switch, approach switch, travel switch.
Irradiation box unified specification, unidirectional vertical hinged door, the direction of opening the door is for opening from left to right.
Irradiation box is batch production, and specification error is limited, and it is unified value that irradiation chamber door inserts firmly the rear exposed connecting rod height in irradiation box outside, casing and door body gapless.If there is following situation: 1, latch normally falls, and does not insert pin-and-hole, though now connecting rod height is not higher than normal value, but chamber door normally do not close, and now width when chamber door body and casing Gap-Ratios normally closed wants large; If 2 connecting rod height are greater than design height, illustrate that latch does not fall the pin-and-hole that inserts door body fixed block; 3, goods expenditure irradiation box outline; No matter occur which kind of situation, pick-up unit all can send warning, falls source, stop chain running, facilitates user to process in time, guarantees irradiation process safety, normal.
brief description of the drawings: Fig. 1 is the structural representation of irradiation chamber door body, casing and chamber door blocking device;
Though Fig. 2 is that connecting rod falls, latch does not insert pin-and-hole, the state that chamber door is not closed;
Fig. 3 is that connecting rod does not fall, the state that chamber door is not closed;
Fig. 4 connecting rod falls latch and inserts pin-and-hole, the state of chamber door closure;
Fig. 5 is the B-B sectional view of Fig. 1.
embodiment:as shown in Figure 1
,irradiation box chamber door occlusion detection system comprises irradiation chamber door body 1, casing 2, chamber door blocking device 3 and several parts of pick-up unit.Wherein chamber door blocking device 3 is by door fixed block 3-4, connecting rod 3-3, web joint 3-2, latch 3-1, frame fixed block 3-5 composition, door fixed block 3-4 is fixedly mounted on the offside of irradiation chamber door body 1 door-hinge, respectively there is up and down one, interior expense hole, at irradiation box casing 2 correspondence positions, connecting rod is set, a latch 3-1 is respectively established by web joint 3-2 in the upper and lower two ends of connecting rod 3-3, frame fixed block 3-5 is positioned on casing 2, for connecting rod 3-3 and irradiation casing 2 are fixed together, expense hole in frame fixed block 3-5, make connecting rod 3-3 to move up and down can not rotate (shown in Fig. 5) along the pin-and-hole of offering on frame fixed block 3-5, latch 3-1, for coordinating with the pin-and-hole of door fixed block 3-4, realizes the closure (Fig. 4) of chamber door.Pick-up unit is arranged on porch, radiation chamber fan road, and the one, detection connecting rod is exposed at the height of irradiation box casing upper end; The 2nd, detect irradiation chamber door body and casing gap width, pick-up unit can be selected the sensors such as optical fiber, optoelectronic switch, approach switch, travel switch.
