Abstract
The utility model discloses a kind of warning device for grate cooler movable grate; Belong to alarm technique field; Its technical essential comprises movable guide plate, described movable guide plate side is provided with approach switch, the signal output part of approach switch is connected with auxiliary reclay, the normally open contact KA1 of auxiliary reclay is in series with very first time relay, and the first time closing normally opened contact KT1 on very first time relay is in series with electric bell; The normally closed interlock KA2 of auxiliary reclay is in series with second time relay, and the second time closing normally opened contact KT2 on second time relay is connected in parallel on the first time closing normally opened contact KT1 two ends; The utility model aims to provide a kind of rational in infrastructure, respond well warning device for grate cooler movable grate; For detection of whether normally operation of grate.
Description
Technical field
Whether normally the utility model relates to a kind of warning device, more particularly, relate in particular to a kind of for detection of the grate warning device of operation.
Background technology
Grate cooler is mainly the cooling operations equipment that is applied in the grogs such as cement mill, the movable grate of grate cooler is in the time of operation, may occur that driving chain breaks or miscellaneous equipment causes the improper running of grate, staff cannot find fault in time, and carry out fault handling, thereby affect the production of production line.
Summary of the invention
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of rational in infrastructure, respond well warning device for grate cooler movable grate is provided.
The technical solution of the utility model is achieved in that a kind of warning device for grate cooler movable grate, comprise movable guide plate, wherein said movable guide plate side is provided with approach switch, the signal output part of approach switch is connected with auxiliary reclay, the normally open contact KA1 of auxiliary reclay is in series with very first time relay, and the first time closing normally opened contact KT1 on very first time relay is in series with electric bell; The normally closed interlock KA2 of auxiliary reclay is in series with second time relay, and the second time closing normally opened contact KT2 on second time relay is connected in parallel on the first time closing normally opened contact KT1 two ends.
Above-mentioned a kind of warning device for grate cooler movable grate, described very first time relay two ends are parallel with pilot lamp.
The utility model adopts after said structure, in the time that movable guide plate does normal to-and-fro movement, provides auxiliary reclay a switching signal, and auxiliary reclay normally open contact KA1 is in series with pilot lamp, now pilot lamp flicker; In movable guide plate is parked in approach switch induction range, auxiliary reclay continues to be powered, armature is attracted to magnetic conductor, normally open contact KA1 closure, normally closed interlock KA2 disconnects, and when normally open contact KA1 closure time is greater than the reciprocating time of movable guide plate, very first time relay sends signal, the first time closing normally opened contact KT1 closure, electric bell gives the alarm; Outside movable guide plate is parked in approach switch induction range, the normally closed interlock KA2 of auxiliary reclay is always closed; In the time that normally closed interlock KA2 closure time is greater than the movable guide plate to-and-fro movement time, second time relay sends signal, the second time closing normally opened contact KT2 closure, and electric bell gives the alarm.The sound sending by light on and off and the electric bell of pilot lamp, staff can find rapidly and handling failure, avoid affecting the running of production line.
Brief description of the drawings
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
In figure: movable guide plate 1, approach switch 2, auxiliary reclay 3, very first time relay 4, electric bell 5, second time relay 6, pilot lamp 7.
Embodiment
Consult shown in Fig. 1, a kind of warning device for grate cooler movable grate of the present utility model, comprise movable guide plate 1, wherein said movable guide plate 1 side is provided with approach switch 2, utilize the reciprocal operation of movable guide plate 1 to make approach switch 2 generations logical, disconnected signal, the signal output part of approach switch 2 is connected with auxiliary reclay 3, the normally open contact KA1 of auxiliary reclay 3 is in series with very first time relay 4, time for detection of movable guide plate 1 in approach switch 2 induction ranges, very first time relay 4 two ends are parallel with pilot lamp 7, the first time closing normally opened contact KT1 on very first time relay 4 is in series with electric bell 5, the normally closed interlock KA2 of auxiliary reclay 3 is in series with second time relay 6, time for detection of movable guide plate 1 outside approach switch 2 induction ranges, the second time closing normally opened contact KT2 on second time relay 6 is connected in parallel on the first time closing normally opened contact KT1 two ends.In the time that movable guide plate 1 does normal to-and-fro movement, pilot lamp 7 glimmers, in movable guide plate 1 is parked in approach switch 2 induction ranges, the normally open contact KA1 closure of auxiliary reclay 3, when normally open contact KA1 closure time is greater than the reciprocal time of movable guide plate 1, very first time relay 4 sends signal controlling electric bell 5 and gives the alarm; Outside movable guide plate 1 is parked in approach switch 2 induction ranges, the normally closed interlock KA2 of auxiliary reclay 3 is always in closure state, when normally closed interlock KA2 closure time is greater than the reciprocal time of movable guide plate 1, second time relay 6 sends signal controlling electric bell 5 and gives the alarm.
Above illustrated embodiment is preferred embodiments of the present utility model, only be used for facilitating explanation the utility model, not the utility model is done to any pro forma restriction, under any, in technical field, have and conventionally know the knowledgeable, if not departing from the scope of technical characterictic that the utility model is carried, utilize technology contents that the utility model discloses to do the local equivalent embodiment that changes or modify, and do not depart from technical characterictic content of the present utility model, all still belong in the scope of the utility model technical characterictic.
