Description

Pigtail recycling in source detects safety-type gamma-ray detection apparatus
Technical field
The utility model relates to radioactive source non-destructive testing defectoscope, more particularly to the source pigtail of the detection source γ nondestructive inspection machine is The device of no safe retrieving.
Background technique
Gamma-ray detection apparatus predominantly detects one of equipment for industrial nondestructive testing field, it is using the source γ as radioactive source.It visits When triage is surveyed, shielding body is drawn into outer catheter with source pigtail in the source γ, executes exposure film making operation, after working, source pigtail It needs accurately to recycle in shield machine body.There are a technical problem underlyings to be the absence of confirmation source pigtail safe retraction for existing defectoscope Confirmation device in place, once there is radioactive source not with source pigtail safe retrieving or source pigtail there is a situation where being broken, it can not from outside Perception, continuing subsequent operations will cause human body radiation to injure because of radiation leaks.Therefore, the safety of defectoscope It can be in urgent need to be improved.
Summary of the invention
The purpose of the invention of the present invention is to provide a kind of assistance operating personnel recognize in time source pigtail whether normally recycling, It improves and detects safety-type gamma-ray detection apparatus using the source pigtail recycling of security protection performance.Pigtail recycling in source provided by the utility model Detect safety-type gamma-ray detection apparatus, technical solution, main technical content is: provenance pigtail recycling detects safety-type gamma-rays Defectoscope, active pigtail safe retrieving detection device is arranged on the drive end bearing bracket of body, this detection device includes the reset of pressure door bolt, pressure door bolt Spring and emergency deadbolt, pressure door bolt are slideably positioned in the core road of drive end bearing bracket, are horizontally placed in front of shield source channels, and pressure, which latches, to be equipped with The cunning chamber channel that source pigtail through-hole and emergency deadbolt are crossed, pressure door bolt top are pierced by drive end bearing bracket;Guiding sliding pin and sense in deadbolt of meeting an urgent need It should sell and be fixed on the saddle plate for crossing sliding chamber channel in parallel, guiding sliding pin and induction pin are located at pressure door bolt front side, rear side, along cunning Chamber channel is slidably matched with pressure door bolt, and guiding sliding pin therein and pressure door bolt front end face lower part are arranged equipped with latch hook upper and lower corresponding, emergency Induction pressure spring is equipped between deadbolt and pressure door bolt.
Pigtail recycling in source disclosed by the utility model detects safety-type gamma-ray detection apparatus technical solution, pigtail safety in source therein Recycling detection device can help operator to find that source pigtail is not normally recycled or is broken in time, and operator is helped accurately to sentence Whether the disconnected source γ has been in safe storage configuration.The technical program has simple and reasonable for structure, and mechanism composition does not influence existing work Make state, guarantees safety and the permanent protective property energy of defectoscope work.
Detailed description of the invention
Fig. 1 is the external structure of the utility model.
Fig. 2,3 are respectively the element structure figure for pressing door bolt and emergency deadbolt.
Fig. 4, Fig. 5 are respectively the cut-away structure chart of normal closed state, readiness of making film.
Cut-away structure chart when Fig. 6, Fig. 7 are respectively normal recycling state, are broken.
Specific embodiment
Pigtail recycling in source disclosed by the utility model detects safety-type gamma-ray detection apparatus, as shown, radioactive source shield 20 are fixedly installed in cylindrical chassis 11, casing 11, shield 20, forward and backward end plate 16,2, the composition of forward and backward end cap 12,3 source γ The body of 23 security masks storage.The rear connector 6 of front connector 13 and rear end cap 3 on drive end bearing bracket 12 is shield source channels The outer connection unit that 19 forward and backward channels extend.
Active pigtail safe retrieving detection device is set on drive end bearing bracket 12.
The source pigtail safe retrieving detection device, including pressure door bolt 18, the reset spring 27 of pressure door bolt 18 and emergency deadbolt 15.
The pressure door bolt 18 is slideably positioned in the core road of drive end bearing bracket 12, is horizontally placed on the front end of shield source channels 19, multiple Position spring 27 is located at the lower part of pressure door bolt 18, and the top 31 of pressure door bolt 18 is pierced by drive end bearing bracket 12.
The cunning chamber channel 33 that pressure door bolt 18 is equipped with source pigtail through-hole 32 and deadbolt 15 of meeting an urgent need is crossed.The emergency deadbolt 15: Pin 24 is parallel is fixed on the saddle plate 16 for crossing sliding chamber channel 33 for guiding sliding pin 10 and induction, and be located at pressure fasten with a bolt or latch on front side of in the of 18, Rear side is slidably matched with pressure door bolt 18, and what guiding 10 front end face of sliding pin was equipped with is pierced by 12 shifting block 9 of drive end bearing bracket, emergency deadbolt 15 and pressure Induction pressure spring 26 is equipped between door bolt 18;It is oriented to sliding pin 10 and pressure 18 front end face lower parts of door bolt is arranged equipped with 30 upper and lower corresponding of latch hook, be used for Cooperate with the annular groove port of source channels external catheter or front connector plug 14.As shown, being pressed to increase emergency deadbolt 15 The stability slid on door bolt 18, induction pin 24 fasten with a bolt or latch in the guide chute 34 on rear side of in the of 18 in pressure and are oriented to sliding.
The source γ 23 is in security mask storage position and after front connector connects dedicated conduits 25, the latch hook of pressure door bolt 18 30 are caught in the port annular groove of plug 14 or dedicated conduits 25, at this point, pressure door bolt 18 source pigtail through-hole 32 just with shield source channels 19 It connects, plug 4 is made to be in reliable air-tight state or the film making of the source γ 23 readiness, the state.Deadbolt 15 of meeting an urgent need is fastened with a bolt or latch with pressure 18 are in upper rest position, and induction pin 24 is in 19 outside of source channels, and source pigtail 7 freely can draw or withdraw, and latch hook 30 is locked Determine dedicated conduits 25, also ensures dedicated conduits 25 when making film work or when source pigtail 7 is not normally recycled and is broken It can not remove.
After film making, if source pigtail 7 is normally recovered to screening-off position, the top 31 for fastening 18 with a bolt or latch is pressed by outer push at this time, With pressure door bolt 18, downlink, the induction pin 24 of downlink can be touched to source pigtail 7 deadbolt 15 of meeting an urgent need together under the action of incuding pressure spring 26, into And continued traveling downwardly by the prevention of source pigtail 7, and door bolt 18 is pressed to may continue to downlink, so that its latch hook 30 is detached from dedicated conduits 25, no longer by about The dedicated conduits 25 of beam can be removed, and fill in the closing of plug 14, complete the source γ reclaimer operation.
When source pigtail 7 fails normally to withdraw or be broken, even if operator does not know under inside information, still routinely operation is pressed The top 31 of door bolt 18 is pushed, deadbolt 15 of meeting an urgent need, with the downlink together of door bolt 18 is pressed, incudes pin in downlink under the action of incuding pressure spring 26 24 do not touch to source pigtail 7, can continue traveling downwardly with pressure door bolt 18, until guiding sliding pin 10 is caught in the port ring of dedicated conduits 25 by top Slot, though latch hook 30 has completely disengaged dedicated conduits 25 at this time, but dedicated conduits 25 still by 15 lock card of emergency deadbolt and can not be by It removes, so that it is abnormal to remind operator not have the recycling of the source γ to occur.It is intended to release the state, it is only necessary to stir shifting block 9.
