Abstract
The utility model discloses a safety detection device for a switch latch of an irradiated box. According to the utility model, two detection travel switches capable of detection of a latch position, safety detection of an E-shaped latch on the irradiated box and real-time alarm signal output for an unclosed latch are respectively disposed on two sides in a forward direction of a hanging frame at front and rear sides at the entrance and exit of the irradiated box. The detection travel switches are connected to a PLC control system in an irradiation main control room via a signal line. The safety detection device for the switch latch of the irradiated box has the beneficial effects of being capable of real-time detection of an unclosed latch and outputting an alarm signal; being simple in structure, safe and reliable; being capable of achieving expected detection results; and eliminating safety risks.
Description
Technical field
The utility model relates to irradiation field, and particularly a kind of irradiation devices suspended chain is carried the switch latch safety detection device of hanging box.
Background technology
60Coradiation device for irradiation processing, conventionally by hanging chain induction system, carry hanging box, in hanging box, be mounted with the irradiation box of product to be irradiated, a general hanging box is high 3 meters, minute two-layer, fills two irradiation box, for machinery vanning is furnished with roller at the bottom of facilitating frame, due to the play in course of conveying, for preventing that irradiation box from protruding from while causing entering the intensive irradiation in the irradiation Room outside hanging box irradiation box knock against each other or clashing into spoke source cover, generally has in hanging box and add E type fence gate outward.Irradiation box is when loading and unloading goods and changing layer operation, sometimes the cylinder actuating length that promotes irradiation box is not in place, can cause E type fence gate not close and put in place, but be stuck in above irradiation box, thereby cause irradiation box to protrude from outside hanging box, the safe operation of irradiation devices is caused to potential safety hazard.
In view of this, the inventor furthers investigate for above-mentioned defect, then has this case to produce.
Summary of the invention
In order to overcome above shortcomings part in prior art, the purpose of this utility model is to provide a kind of device that can automatically detect the E type fence gate position of the switch of installing in irradiation box, and the E type fence gate not shutting is reported to the police, so that alert device operating personnel process in time, the irradiation box switch latch safety detection device eliminating safe hidden trouble.
For achieving the above object, the utility model adopts following concrete technical scheme: a kind of irradiation box switch latch safety detection device, it is characterized in that: described safety detection device respectively arranges a detection travel switch that can pair of latches position detects to, the E type bolt position in irradiation box is carried out safety detection and the bolt not shutting carried out to the output of Realtime Alerts signal for the working direction both sides of both sides, front and back hanging box in turnover irradiation box, and described detection travel switch is connected with the PLC control system in irradiation master-control room by signal wire.
Preferably, described detection travel switch is installed on both sides, the front and back vertical columns of irradiation box working direction.
Adopt technique scheme, irradiation box switch latch safety detection device described in the utility model, the beneficial effect having is:
1) can detect in real time the bolt not shutting, and have alerting signal output;
2) apparatus structure is simple, safe and reliable, can reach the detection effect of expection, eliminates safe hidden trouble;
3) this device can carry out safety interlocking with carrier chain, thoroughly eliminates safe hidden trouble.
Accompanying drawing explanation
Fig. 1 is that irradiation box switch latch safety detection device described in the utility model is used view.
Embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Irradiation box switch latch safety detection device as described in the utility model in Fig. 1 is used as shown in view, irradiation box open and close latch system comprises E type bolt 1 movable up and down, the cylinder bolt mechanism 2 that opens the door, E type bolt 1 is located on the column 3 of both sides, front and back hanging box 5 of hanging box 5 turnover irradiation box 4, and the cylinder bolt mechanism 2 that opens the door is installed on the station frame of turnover irradiation box 4; Safety detection device is for respectively arranging a detection travel switch 6 that can pair of latches position detects to, the E type bolt position in irradiation box is carried out safety detection and the bolt not shutting carried out to the output of Realtime Alerts signal in hanging box 5 working direction both sides, detect travel switch 6 and be installed on both sides, the front and back vertical columns 7 of irradiation box 3 working direction, and detection travel switch 6 is connected with the PLC control system in irradiation master-control room by signal wire.
During concrete use, suspender is in loading or when changing layer operation and completing, likely because container distortion or the skew of container position (suspender bolt position can be high when normal) not in place when suspender bolt is fallen after rise detect the both sides that travel switch is arranged on suspender traffic direction, a little more than the normal position of suspender bolt.When bolt falls suspender not in place at operation process safety detection travel switch after rise, suspender bolt will touch detection travel switch, cause detecting travel switch action, detect travel switch and to the PLC in master-control room, send the signal that bolt does not close by signal wire.PLC receives after the signal that bolt do not close, after the automatic processing of CPU internal program, send the alarm sound that bolt does not close, field personnel should process suspender bolt immediately after hearing chimes of doom, presses reset switch button after finishing dealing with, and removes the alarm that bolt does not close.When the alarm sound not closing when bolt rises, field personnel fails in time suspender bolt to be processed, and the 30 seconds rear drive chains of time delay of reporting to the police will be automatically out of service, to eliminate safe hidden trouble.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
Claims (2)
1. an irradiation box switch latch safety detection device, it is characterized in that: described safety detection device respectively arranges a detection travel switch that can pair of latches position detects to, the E type bolt position in irradiation box is carried out safety detection and the bolt not shutting carried out to the output of Realtime Alerts signal for the working direction both sides of both sides, front and back hanging box in turnover irradiation box, and described detection travel switch is connected with the PLC control system in irradiation master-control room by signal wire.
2. a kind of irradiation box switch latch safety detection device according to claim 1, is characterized in that: described detection travel switch is installed on both sides, the front and back vertical columns of irradiation box working direction.
