Abstract
The invention discloses a kind of safety door for vertical shaft electric control lock, primarily of AC transformer, limit switch, spacing magnet steel, control circuit, latching circuit composition, control circuit, latching circuit are arranged in switch box, switch box is arranged on the ingate of stage casing, described spacing magnet steel is arranged on the side of cage, and limit switch is arranged on the ingate in stage casing.Self-control lock is installed simple, and easy to operate, be not afraid of humidity, cost is low.
Description
Technical field the present invention relates to a kind of safety shaft door lock, is specifically related to a kind of safety door for vertical shaft self-control lock.
Background technology vertical shaft is the major arteries of mine hoisting, and it brings considerable benefit to enterprise, and safety shaft Ye Shi bargh is to a heavier link of looking simultaneously.Due to the imperfection of safety shaft facility, therefore cause many casualty accidents, the machinery on market and automatically controlled safety shaft door lock, as: safety door for vertical shaft mechanical lock manufacture with install cumbersome, cost is high, uses very heavy, particularly very inconvenient in vertical shaft maintenance; The shortcoming of safety door for vertical shaft Electronic control lock is complex structure, and cost is high, and because the environment of down-hole is moister, the electronic component used easily damages, and brings a lot of inconvenience to production and maintenance.
Summary of the invention is in order to overcome defect and the weak point of existing safety shaft door lock, the invention provides and give a kind of safety door for vertical shaft self-control lock, cost is low, simple structure, wet environment operation can be adapted to, effectively ensure the safety of personnel, prevented from operation, occur that workman is strayed into vertical shaft, cause falling accident.
The technical scheme that the present invention provides for technical solution problem is as follows:
A kind of safety door for vertical shaft electric control lock, primarily of AC transformer, limit switch, spacing magnet steel, control circuit, latching circuit composition, control circuit, latching circuit are arranged in switch box, switch box is arranged on the ingate of stage casing, described spacing magnet steel is arranged on the side of cage, and limit switch is arranged on the ingate in stage casing.
Described control circuit by 36V power supply through normally closed contact ZC, FC mono-tunnel connect intermediate relay, another road is through limit switch normal opened contact K2 connecting time relay K T normally closed contact, intermediate relay KM1 and the time relay KT in parallel with time relay KT normally closed contact, intermediate relay KM1.
Described latching circuit is connected through the normal opened contact of electric control lock with intermediate relay KM1 by 12V power supply one tunnel after AC transformer transformation, connect with the normal opened contact of intermediate relay KM1 through lamp of unblanking in one tunnel, connect through the normal opened contact of run indicator with intermediate relay KM2 in one tunnel, three parallel circuit parallel connections.
The normal opened contact hand push button QA in parallel of the intermediate relay KM1 connected with electric control lock in described latching circuit.
The invention has the advantages that: self-control lock is installed simple, and easy to operate, be not afraid of humidity, cost is low.
Description of drawings 1 is the schematic circuit diagram of control circuit of the present invention;
Fig. 2 is the schematic circuit diagram of latching circuit of the present invention;
Fig. 3 is the normal opened contact of limit switch;
Fig. 4 is the constructional drawing of spacing magnet steel;
Fig. 5 is the block scheme of safety door for vertical shaft electric control lock principle.
Detailed description of the invention safety door for vertical shaft electric control lock is primarily of AC transformer, limit switch, spacing magnet steel, control circuit, latching circuit forms, control circuit, latching circuit are arranged in switch box, switch box is arranged on the ingate of stage casing, described spacing magnet steel is arranged on the side of cage, and limit switch is arranged on the ingate in stage casing.
The principle of work of safety door for vertical shaft electric control lock is: 36V power supply is through normally closed contact ZC, FC, to KM2 power supply, after KM2 obtains electric rear adhesive, the normal opened contact of KM2 closes, at this moment run indicator lights, when spacing magnet steel runs to the ingate in each stage casing, limit switch and spacing magnet steel meet, the limit switch normal opened contact K2 and the spacing magnet steel S.N that are arranged on stage casing meet, the normal opened contact K2 of limit switch closes, at this moment intermediate relay KM1, time relay KT adhesive, the closed indicator lamp of unblanking of normal opened contact of intermediate relay KM1 lights, 12V power supply makes electric control lock R obtain electric-opening by KM1 normal opened contact, at this moment, the safety door in stage casing is opened.The normally closed contact of time relay KT is after electric control lock R opens 4,5 seconds, and time relay KT normally closed contact disconnects, and electric control lock R dead electricity, prevents electric control lock R to be energized for a long time and burn.When intermediate relay KM1 breaks down, circuit can be connected by hand push button QA, electric control lock R is opened.
The feature of safety door for vertical shaft electric control lock is:
(1) when cage runs, the automatic lock of safety door in well head and each stage casing is dead, and run indicator is bright.
(2) when cage runs to the stage casing of work, after coming to a complete stop, safety lock is opened automatically, and indicator lamp of unblanking is bright.
(3) cage is not when the stage casing worked, and safety door cannot be opened.
(4) personnel, mine car shut safety door after tank, safety lock is automatically locked, and cage runs.
(5) self-control lock has two kinds of control methods, Non-follow control and automatically control.
(6) safety voltage that self-control lock uses is 36V, 12V respectively.
(7) self-control lock is installed simple, and easy to operate, be not afraid of humidity, cost is low.
Claims (2)
