Abstract
The utility model relates to a safety door used for a gamma-irradiation device test wire channel inlet. The safety door comprises a test wire channel, a test wire conveying chain, a test box, an optoelectronic switch, an electromagnetic switch and a safety door body. The test wire conveying chain used for hanging and conveying the test box is arranged in the test wire channel, and the safety door body is arranged in the test wire channel, wherein opening and closing of the safety door body are controlled by the optoelectronic switch and the electromagnetic switch in a matched mode. When the text box is hung on the test wire conveying chain, enters a radiation chamber and reaches the safety door body, the test box triggers an optoelectronic signal controller, test wires stop conveying the test box, the safety door body is opened at the same time, the test wires begin to convey when the safety door body is completely opened, the test box triggers the optoelectronic signal controller after passing through the safety door body, the test wires stop conveying the test box, the safety door body is closed at the same time, and after the safety door body is closed, the test wires continue to operate to convey the test box to a prescribed position of the radiation chamber. The safety door used for the gamma-irradiation device test wire channel inlet is reasonable in layout, simple in structure, convenient to use, safe and reliable, and suitable for multiple-channel hung-type test wires. By arranging the safety door at the position of the test wire channel inlet, automatic operation can be achieved, safety can be guaranteed, and radiation accidents can be avoided.
Description
Technical field
The utility model relates to radiotechnology field, especially a kind of safety door that is applied to Dynarad test wire feeder connection.
Background technology
Dynarad is the important component part of civilian nuclear technology, and the Co 60 active source that Dynarad uses is to have dangerous I class source, in case the accident of meeting accident will cause serious personal casualty, bad social influence and serious economic loss.This test wire is small-sized suspension conveying-type irradiation devices, is the corollary equipment of BTF-II type Dynarad, is mainly used in scientific research and sample irradiation.Because existing weaponry and equipment does not arrange safety door at test wire feeder connection place, may cause having personnel's accident to enter, it is dangerous that radiation accident occurs.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of safety door that is applied to Dynarad test wire feeder connection is provided, be intended to solution personnel's accident in the irradiation operational process and enter and cause radiation accident, the warranty test line normally uses simultaneously.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of safety door that is applied to Dynarad test wire feeder connection, comprise test wire passage, test wire chain, proofing box, photoelectric switch, electromagnetic switch and safety door, be equipped with in the test wire passage and hang the test wire chain that transmits proofing box, it is characterized in that: be equipped with one in described test wire passage and coordinate by photoelectric switch and electromagnetic switch the safety door of controlling automatic open and close.
And described safety door is coordinated by electromagnetic switch and photoelectric switch to be controlled, and is specially: in the test wire passage of safety door one side, photoelectric switch G1 is installed, photoelectric switch G2 and photoelectric switch G3 are installed in the test wire passage of safety door opposite side; At the safety door off position, one electromagnetic switch C1 is installed, the safety door open position is equipped with another electromagnetic switch C2.
Advantage of the present utility model and good effect are:
The utility model is rationally distributed, simple in structure, esy to use, safe and reliable, be applicable to test wire and the manufacturing line of multiple channel type, at test wire or manufacturing line feeder connection place, the intrinsic safety air cock is set, can automatically move unlatching, close, warranty test line safety, effectively stop personnel's accident and enter, avoid occuring radiation accident.
Description of drawings
Fig. 1 is the utility model plan structure schematic diagram;
Fig. 2 is the structure side view of safety door opening of the present utility model;
Fig. 3 is the structure side view of safety door closed condition of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
Photoelectric switch in Figure of description and electromagnetic switch installation site are schematically, setting actual in the place.
A kind of safety door that is applied to Dynarad test wire feeder connection, comprise test wire passage 4, test wire chain 5, proofing box 2, photoelectric switch, electromagnetic switch and safety door 3, be equipped with in the test wire passage and hang the test wire chain that transmits proofing box, this test wire chain drives operation by motor 1, test wire passage front portion is equipped with one and coordinates by photoelectric switch, electromagnetic switch the safety door of controlling open and close, and this safety door drives open and close by cylinder (in figure not label).
Innovative point of the present utility model is:
Described test wire feeder connection place is equipped with a closable safety door, safety door is coordinated by electromagnetic switch and photoelectric switch to be controlled automatically, wherein photoelectric switch is for detection of the proofing box position signal, electromagnetic switch is for detection of the safety door position signal, concrete installation site is, in the test wire passage of safety door one side, photoelectric switch G1 is installed, photoelectric switch G2 and photoelectric switch G3 are installed in the test wire passage of safety door opposite side; At the safety door off position, one electromagnetic switch C1 is installed, triggers electromagnetic switch C1 when safety door is closed; The safety door open position is equipped with another electromagnetic switch C2, triggers electromagnetic switch C2 when safety door is opened.
The concrete installation site of described photoelectric switch G1, photoelectric switch G2, photoelectric switch G3, electromagnetic switch C1 and electromagnetic switch C2 arranges according to actual place size.
This is not described in detail for electric-controlled circuit structure.
Below in conjunction with accompanying drawing, the utility model specific works is described, the step that proofing box enters radiation chamber is:
The first step, proofing box is when initial position, and safety door is in closed condition;
Second step, starting outfit, proofing box is moved by motor-driven, moves to the position of triggering photoelectric switch G1 when proofing box, the motor time-out, proofing box suspends wait, and the safety door unlatching is until trigger electromagnetic switch C2, motor continuation operation driving proofing box continuation operation;
The 3rd step, continue to move to the position of triggering photoelectric switch G3 when proofing box, motor suspends, and safety door is closed until trigger and be arranged on electromagnetic switch C1, and motor continues to move to the radiation chamber assigned address.
The concrete steps that radiation chamber is left in proofing box are:
The first step, proofing box move to and trigger photoelectric switch G2, and motor suspends, and the test wire door is opened into and triggers electromagnetic switch C2, and motor continues the operation of motoring ring test case.
Second step, when initial position was got back in proofing box, motor stopped, and the test wire door is closed.
