Abstract
The invention relates to a building safety door, in particular to an anti-pinch X-ray protection door. The anti-pinch X-ray protection door comprises an upper rail and a lower rail which are arranged at the upper end and the lower end of a door opening, wherein the two rails extend towards the left side; an X-ray protection door body is arranged between the upper rail and the lower rail through an upper group of guide rollers and a lower group of guide rollers; the lower group of the guide rollers comprise a driven wheel and a driving wheel; the driving wheel is provided with a driving motor; the anti-pinch X-ray protection door is characterized in that a column of four infrared emitters are arranged on the right side of the door opening; four infrared receivers are arranged on the right side of the X-ray protection door body in a manner of corresponding to the four infrared emitters and are connected with a relay at the same time in a control manner; the relay is connected with a controller for controlling the driving motor. According to the anti-pinch X-ray protection door, the safety problem that a person forcibly entering the protection door during closing of the door is easy to hurt by pinching is solved; the anti-pinch X-ray protection door is mainly used in an X-ray working machine room.
Description
Technical field
The present invention relates to building safety door, especially a kind of anti-pinch X-ray protection door of hurting sb.'s feelings.
Background technology
Along with market competition is day by day fierce; the raising of national sector standard; available 250KV X-ray machine X of past carries out workpiece transillumination; need now with 300KV and even higher voltage apparatus transillumination; this has directly caused exposure service depot's body of wall requirement than thicker in the past; supporting plumbous door weight is increasing; protective door more and more thick and heavy (what have weighs several tons); without any protection in the situation that; protective door close in service; may occur to squeeze wound to the staff and the pedestrian that enter suddenly exposure room, gently injured, severe one threat to life.
Summary of the invention
Object of the present invention will solve existing exposure service depot protective door does not exactly have safety precautions, easily squeezes the problem of hurting sb.'s feelings, and a kind of anti-pinch X-ray protection door of hurting sb.'s feelings is provided.
Concrete scheme of the present invention is: improve for existing protective door, it includes and is arranged on getting on the right track and lower railway of the upper and lower two ends of door opening, two tracks extend to the left, on, between lower railway, pass through upper, lower two groups of guide rollers are provided with X-ray protection door, the one group of guide roller in below includes a driven pulley and a driving wheel, driving wheel is fitted with drive motors, it is characterized in that: four RF transmitters of row are installed on the right side of door opening, on the right side of X-ray protection door, corresponding four RF transmitters are provided with four infrared receivers, four infrared receivers relay of control connection simultaneously, relay connects controller control drive motors.
Described in the present invention in four RF transmitters one of below overhead 300mm is high, the spacing between four RF transmitters is 200mm.
Protective door of the present invention is owing to being provided with four RF transmitters and four corresponding infrared receivers, and under the prerequisite without any stopping, signal feedback, to controller, makes protective door can normally close operation.When there being any a branch of infrared rays of people or object blocks, will cause infrared signal to be interrupted, by relay, controller, drive motors is quit work immediately, make the operation of protective door phase down.Thereby reach the protective effect that anti-pinch is hurted sb.'s feelings.The present invention is simple in structure, and reliable operation is suitable for the improvement of various exposure room protective doors.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-gets on the right track, 2-guide roller, 3-protective door, 4-infrared receiver, 5-door opening, 6-RF transmitter, 7-driven pulley, 8-lower railway, 9-driving wheel, 10-drive motors, 11-controller, 12-relay.
The specific embodiment
Referring to Fig. 1, the present invention includes be arranged on door opening Shang Xia 5 two ends get on the right track 1 and lower railway 8, two tracks extend to the left, on, between lower railway 1 and 8, pass through upper, lower two groups of guide rollers 2 are provided with X-ray protection door 3, the one group of guide roller 2 in below includes a driven pulley 7 and a driving wheel 9, driving wheel 9 is fitted with drive motors 10, particularly: four RF transmitters 6 of row are installed on the right side of door opening 5, on the right side of X-ray protection door 3, corresponding four RF transmitters 6 are provided with four infrared receivers 4, four infrared receivers 4 relay 12 of control connection simultaneously, relay 12 connects controller 11 and controls drive motors 10.
Described in the present embodiment in four RF transmitters 6 one of below overhead 300mm is high, the spacing between four RF transmitters 6 is 200mm, above size also can be adjusted accordingly according to actual conditions.
