Abstract
The invention discloses a vertical shaft safety gate self-controlled lock. The vertical shaft safety gate self-controlled lock is mainly composed of an alternating-current transformer, a limiting switch, limiting magnetic steel, a control circuit and a latching circuit, wherein the control circuit and the latching circuit are mounted in a power distribution box, the power distribution box is mounted on a middle horsehead gate, the limiting magnetic steel is mounted on one side of a cage, and the limiting switch is mounted on an interrupted horsehead gate. The vertical shaft safety gate self-controlled lock is easy to install, convenient to operate, resistant to damp and low in cost.
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 that the major arteries ，Ta Gei enterprise of mine hoisting has brought considerable benefit, and safety shaft Ye Shi bargh is to a heavier link of looking simultaneously.Due to the imperfection of safety shaft facility, many casualty accidents, the machinery on market and automatically controlled safety shaft door lock have therefore been caused, 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 the electronic control lock of safety door for vertical shaft is complex structure, and cost is high, and because the environment of down-hole is moister, the electronic component using 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 to a kind of safety door for vertical shaft self-control lock, cost is low, simple structure, can adapt to wet environment operation, effectively ensure personnel's safety, prevented from occurring that workman is strayed into vertical shaft in operation, caused falling accident.
The present invention for the technical scheme that technical solution problem provides as follows:
A kind of safety door for vertical shaft electric control lock, mainly by AC transformer, limit switch, spacing magnet steel, control circuit, latching circuit, formed, 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 a side of cage, and limit switch is arranged on the ingate of interruption.
Described control circuit connects intermediate relay by 36V power supply through normally closed contact ZC ,FC mono-tunnel, and another road is through limit switch normal opened contact K
2connecting time relay K T normally closed contact, intermediate relay KM
1with with time relay KT normally closed contact, intermediate relay KM
1time relay KT in parallel.
Described latching circuit by AC transformer transformation after 12V power supply one tunnel through electric control lock and intermediate relay KM
1normal opened contact series connection ，Yi road through lamp and the intermediate relay KM of unblanking
1normal opened contact series connection ，Yi road through run indicator, connect with the normal opened contact of intermediate relay KM2, three parallel circuit parallel connections.
The intermediate relay KM connecting with electric control lock in described latching circuit
1normal opened contact hand push button QA in parallel.
The invention has the advantages that: self-control lock is installed simple, easy to operate, is not afraid of humidity, and cost is low.
The schematic circuit diagram that description of drawings 1 is 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.
Specific embodiment safety door for vertical shaft electric control lock is mainly by 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 a side of cage, and limit switch is arranged on the ingate of interruption.
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 KM
2power supply, KM
2obtain after electric rear adhesive KM
2normal opened contact closed, at this moment run indicator lights, when spacing magnet steel runs to the ingate of each interruption, limit switch and spacing magnet steel meet, and are arranged on the limit switch normal opened contact K in stage casing
2meet with spacing magnet steel S.N, the normal opened contact K of limit switch
2closure, at this moment intermediate relay KM
1, time relay KT adhesive, intermediate relay KM
1the normal opened contact closure indicator lamp of unblanking light, 12V power supply passes through KM
1normal opened contact makes electric control lock R obtain electric-opening, and at this moment, the safety door in stage casing is opened.The normally closed contact of time relay KT is opened after 4,5 seconds at electric control lock R, and time relay KT normally closed contact disconnects, and electric control lock R dead electricity prevents that electric control lock R from switching on and burning for a long time.Intermediate relay KM
1while breaking down, can connect circuit 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 moves, 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 the indicator lamp of unblanking is bright.
(3) cage is not when the stage casing of work, and safety door cannot be opened.
(4) on personnel, mine car, after tank, shut safety door, safety lock is automatically locked, cage operation.
(5) self-control lock has two kinds of control methods, manually controls and automatically controls.
(6) what self-control lock was used is that safety voltage is respectively 36V, 12V.
(7) self-control lock is installed simply, easy to operate, is not afraid of humidity, and cost is low.
Claims (2)
1. a safety door for vertical shaft electric control lock, it is characterized in that: mainly by 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 a side of cage, and limit switch is arranged on the ingate of interruption;
