Abstract
The utility model discloses a safety interlock device for industrial fault detection carrying out security control for the existing flaw detector. The bad result caused by the flaw x-ray radiating human body can be prevented. The major technique is that an audible and visual alarm is arranged in the flaw detection chamber; the entrance and exit point of the flaw detection chamber are provided with a parking gate travel switch. The staff in the flaw detection and the operating staff of the flaw detector respectively hold an emergency switch and a controlling switch of circumvention proof. The device has simple line construction and can be linked with multiple flaw detectors. The flaw detector can be controlled safely and the work efficiency of the industry flaw detection can be improved.
Description
A kind of industrial flaw detection safety interlock.
Industrial, the pressure vessel weld bond is checked, is extensive use of the x ray flaw detector, because the x ray is harmful to health, therefore, the measure of the anti-evil of X-ray detectoscope is very important.Existing defectoscope does not have the measure of anti-evil to scene of detecting a flaw and operating personnel.Though defectoscope by the next door, the thing of being visited in the crack detection room is detected a flaw, but the personnel that often occur in the crack detection room also withdraw (as, the obedient sheet of certain staff flaw detection place in pressure vessel at the end, do not hear that other people call out and withdraw sound) or other staff be strayed into phenomenons such as crack detection room, make the existing staff who hinders of flaw detection or be strayed into the on-the-spot personnel of flaw detection, because of the defectoscope control system lacks the measure of the anti-evil of necessary security, occurred repeatedly by x radiation exposure incident.Even more serious is, utilize the x ray flaw detector directly to someone irradiation (joke or have a mind to and frame), and can not be felt that " occupational illness " of Chu Xianing or the be unwilling phenomenon of being engaged in this work is brought harmful effect and consequence to individual or unit therefrom according to the people.
The utility model purpose: design a kind of industrial flaw detection safety interlock of the on-the-spot domestic and foreign work personnel that detect a flaw being taked anti-evil safeguard measure.
The utility model technical solution:
Audible-visual annunciator is set inside and outside crack detection room, and place, crack detection room gateway is provided with a position travel switch, the interior staff of crack detection room and defectoscope operating personnel and holds EmS and master cock respectively.This device primary structure is; by the master cock normally opened contact; crack detection room door position travel switch normally opened contact; the jack normally closed contact; the EmS normally closed contact; relay coil and time relay delayed contact are connected successively; make each position switch of this branch road and contact only under designated state; relay coil is just switched on; its normally opened contact is connected each defectoscope bulb high tension loop respectively, makes defectoscope enter duty, in the course of the work; each situation that takes place is respectively by sound; light is reported to the police, and controls defectoscope automatically; take safeguard measure.
The utility model advantage:
1, because master cock has only by special key and could start this device, control the defectoscope high tension loop, therefore, except that the operator with this key, other people can not arbitrarily operate defectoscope, have avoided the human accident generation.
2, the EmS of this device setting has two, and one is positioned on the flaw detection interior walls, and another can be carried, be used for the interior staff of crack detection room stays in the crack detection room for a certain reason by mistake, can connect this switch this moment, cuts off bulb high voltage control loop, guarantees to stay personal security to withdraw by mistake.
3, be provided with chronotron, the personnel that prenotice in 8～10 seconds before defectoscope work inside and outside the crack detection room withdraw or away from crack detection room.
4, at place, crack detection room gateway door position switch is set, in the time of can preventing defectoscope work, people are strayed into crack detection room.
5, the defectoscope course of work or when one of above-mentioned situation occurring all report to the police by audible-visual annunciator, and this device is taked the corresponding protection measure automatically.
6, this device can connect machine with several defectoscopes simultaneously, and under its safety interlock control, safety can be done, and improves the flaw detection work efficiency.
Below in conjunction with description of drawings the utility model most preferred embodiment.
Accompanying drawing is the utility model line construction schematic diagram.
