Description
Technical field
The utility model relates to industrial irradiation device technique field, and the optoelectronic switch that is specifically related to a kind of irradiation devices is checked and verified device.
Background technology
In order to guarantee irradiation devices operating personnel's in the irradiation production run personal safety, at present, one of technical measures that domestic irradiation devices are taked are in door inboard, product gateway and personnel channel's entrance door installed inside " anti-people's optoelectronic switch ".In case there is the people to be strayed into radiation area at the device run duration, optoelectronic switch will be triggered then and to report to the police immediately and fall the source automatically, and the source frame that is about to be equipped with radioactive source rolls back home, is not shone by the ray mistake with the assurance personnel.For guaranteeing that this safety practice is reliably effective, must make regular check on checking to the validity of optoelectronic switch.But because unapproachable radiation areas of personnel when producing, its installation site, inspection work must be carried out after the source falls in stopping production, and can only check optoelectronic switch itself this moment, can't verify but whether its electric control loop can correctly finish the function of falling the source.In order to address this problem, individual device has adopted the electric remote control device to check, mechanism's complexity not only, and under radiation environment, also have the possibility that lost efficacy.
Summary of the invention
The purpose of this utility model is the defective at prior art, a kind of optoelectronic switch testing fixture of full machinery is provided, can at the source chord position during in duty, check and verify the actual validity of anti-people's optoelectronic switch, guarantee its reliable effectively work all the time.
Realize the technical scheme of the utility model purpose: a kind of optoelectronic switch is checked and verified device, comprise slideway support, movable shadow shield, wire rope, leading block assembly, fixed mechanism, upper limit bar and lower limit bar, the optoelectronic switch reflector is fixedly arranged on the base plate of described slideway support, the both sides of slideway support base plate are welded with the groove shape slideway of die mould, movable shadow shield is installed on the described slideway, movable shadow shield upper end is connected with an end of wire rope, and wire rope places on the fixed mechanism through the leading block assembly traction other end; The upper limit bar is equipped with in the slideway upper end of slideway support, in the bottom of slideway support base plate the lower limit bar is housed.
Aforesaid a kind of optoelectronic switch is checked and verified device, and the leading block assembly comprises two leading blocks and passes the pre-pipe laying of shielding body of wall.
Aforesaid a kind of optoelectronic switch is checked and verified device, and fixed mechanism is the fixedly support that is complementary with the wire rope end handle.
Effect of the present utility model is: the reflector of optoelectronic switch is installed in the slideway support, slideway in the support is provided with the movable shadow shield by the haulage cable suspention, wire rope causes safe operational zone through leading block, by the place height of operating personnel by folding and unfolding wire rope control shadow shield, rush the situation of photoelectricity with simulation personnel mistake.This device is an easy full mechanical, and the malfunctioning possibility of electric remote control device has been avoided in manual operation.In addition, this device can at the source chord position during in duty, be checked and verified the actual validity of anti-people's optoelectronic switch.
