Abstract
A kind of radiographic inspection interlock, it relates to a kind of X-ray detection apparatus X.It is limited for serviceable life that the utility model solves lead limit switch, and during closedown, impact causes greatly lead limit switch to hit even to break from its installation site, and then provides error signal; And the thermoluminescence switch that existing self reliant rebuilding uses can produce misoperation when radiation irradiation, and suffer damage, also can affect the problem in serviceable life.The utility model radiographic inspection interlock is by warning device, infrared electro pick-up unit, and roentgen dose X pick-up unit is formed.The utility model adopts infrared electro and Geiger tube radiation dose redundancy detection, reliable and stable signal can be provided, the locking of crack detection room personnel protection door in flaw detection process can also be realized, prevent the generation of by mistake irradiating, greatly promote crack detection room radiation protection level.
Description
Technical field
The utility model relates to a kind of X-ray detection apparatus X.
Background technology
The requirement of shelter of China to radioactive isotope and isotope application is more and more higher, more and more concrete, the protection level of industrial x-ray crack detection room is also more and more paid attention to, install door-machine interlock safety device is the project enforced in relevant national standard, door-machine safety interlock (comprising the door-machine interlocking device of Tech. Physics Inst., Sci. Academy of Heilongjiang Prov.'s development nineties) that current each industrial enterprise uses uses lead limit switch substantially to the detection of protective door state, in use procedure, failure rate is high, and impact is produced.The interlocking connection that novel χ ray flaw detector (the German ERESCO 65MFS) instructions of Bei Che group (former Qiqihar Vehicle Factory) buying in 2007 provides still uses lead limit switch, and the interlocking related description of each Novel flaw detection instrument that Dandong produces also is like this.Lead limit switch is mechanical contact-type, serviceable life is limited, and more seriously protective door is all lead protection door, weight is large, impact during closedown is very large, lead limit switch can be caused to hit even break from its installation site, and then occur that protective door does not close position and provides error signal, cause the protective action of door-machine interlock safety device not play and cause possible mistake to irradiate.Some factory and enterprises (as Harbin Turbine) self reliant rebuilding once used thermoluminescence switch (Photoelectric infrared switch), although it is low to χ, gamma-rays susceptibility, but because during flaw detection, radiation irradiation amount is large, so can misoperation be produced, and be in radiation field due to equipment self, can suffer damage, also can affect serviceable life.
Utility model content
The utility model is limited for serviceable life in order to solve lead limit switch, and during closedown, impact causes greatly lead limit switch to hit even to break from its installation site, and then provides error signal; And the thermoluminescence switch that existing self reliant rebuilding uses can produce misoperation when radiation irradiation, and suffer damage, also can affect the problem in serviceable life, and a kind of radiographic inspection interlock provided.
Radiographic inspection interlock is by warning device, infrared electro pick-up unit, and roentgen dose X pick-up unit is formed; Wherein warning device is provided with danger button in crack detection room inside; Roentgen dose X pick-up unit comprises power-supply filter, high pressure generator, Geiger counter tube, pulse processing circuit, burst transmissions circuit and probe composition; Roentgen dose X pick-up unit is aluminum hollow cylinder, and inside is provided with circuit board and counter tube, and counter tube is fixing, and circuit board is connected with accessory power outlet on circuit boards, and outer cover has aluminum hollow cylindrical sleeve.
Whether warning device is used for monitoring protection door and closes completely, and whether have dosage to reveal when carrying out radiographic inspection, whether crack detection room inside has the situations such as personnel stop.
The utility model adopts infrared electro and Geiger tube radiation dose redundancy detection, reliable and stable signal can be provided, the locking of crack detection room personnel protection door in flaw detection process can also be realized, prevent the generation of by mistake irradiating, greatly promote crack detection room radiation protection level.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Fig. 2 is the circuit diagram of the utility model roentgen dose X pick-up unit.
