Abstract
Provided is a mine hoisting machine electronic control system. An intermediate relay is increased between an allowable switch series circuit on a well mouth signal platform and a programmable logic controller cabinet module input port. A structure that the intermediate relay is increased between the allowable switch series circuit on the well mouth signal platform and the programmable logic controller cabinet module input port is adopted. By the structure, a normally-opened point of the intermediate relay controls whether to work, so that an induced current does not directly affect an induced electricity programmable logic controller system, direct effect of induced electricity on the programmable logic controller system is removed , and safe operation of equipment can be ensured. Through continuous use of more than two years, failure phenomenon does not occur again, and effect is obvious. The mine hoisting machine electronic control system is simple in method, easy to implement, obvious in effect, convenient to maintain, and suitable for humid environment under a mine well, and completely solves the direct effect of the induced current on the programmable logic controller system, and enables allowed driving to have a safety guarantee function.
Description
Technical field
The utility model relates to the mine hoist field, specifically a kind of Electric Control System of Mine Hoister.
Background technology
The multi-rope friction type mine hoist is being undertaken the lifting task of personnel and material.Wherein the electric-control system of gig comprises technology controlling and process, Stroke Control, supervisory system, safety return circuit, brake system, speed governing system and signal system etc.Electric-control system adopts programmable logic controller (PLC) (PLC) technology and DC speed regulation technology.Electric-control system is directly connected to the safe handling of gig, for ensure the personnel in the pit can be safely cage up and down, each stage casing simple signal platform is installed a permission switch in the down-hole, with their series connection together, connect with the permission switch on the hole top signal platform again, be input to programmable logic controller (PLC) (PLC) cabinet module input mouth, whether this port control convenience in program turns round, and realizes that down-hole switch is to the control action of gig.As shown in Figure 2, wherein 0YKA allows switch on the hole top signal platform, and 1YKA～7YKA allows switch on 1～7 stage casing signal bridge of down-hole.When gig need to turn round, allow switch 0YKA～7YKA to be in closure state.If cage is parked in the stage casing, down-hole when having personnel and material up and down, the signalman disconnects the permission switch, makes programmable logic controller (PLC) (PLC) cabinet module input mouth (00302) be in off state, guarantees that gig is in the emergency state.But because mine down-hole inclement condition, the moist water of the borehole wall is large, produce easily inducing current, present electric-control system is not eliminated the inducing current device, cause as the signalman to disconnect the permission switch, gig is when dead ship condition, and input port (00302) also is in normal working, this state causes the maloperation generation person or equipment breakdown easily, gives safety in production lower hidden danger.
The utility model content
Technical problem to be solved in the utility model is to overcome the inducing current that mine down-hole in the prior art produces impact causes the shortcoming that causes easily the maloperation generation person or equipment breakdown and a kind of Electric Control System of Mine Hoister that provides on electric-control system.
Adopt following technical scheme for solving technical matters of the present utility model:
A kind of Electric Control System of Mine Hoister increases by an intermediate relay with allowing on the hole top signal platform between switch circuit series and the programmable logic controller (PLC) cabinet module input mouth.
Described intermediate relay is installed in the hole top signal platform.
The utility model is to adopt to allow to increase between switch circuit series and programmable logic controller (PLC) (PLC) the cabinet module input mouth structure of an intermediate relay on the hole top signal platform.By this structure, by intermediate relay often make war control whether work, inducing current is not directly exerted an influence to induction electricity programmable logic controller (PLC) (PLC) system, eliminate inducing current to the direct impact of programmable logic controller (PLC) (PLC) system, can guarantee again the device security running, through the continuous use more than 2 years, above-mentioned phenomenon of the failure did not appear again, and effect is apparent in view.The utility model method is simple, and is easy to implement, successful, easy to maintenance, relatively be suitable for the relatively moister environment of mine down-hole, thoroughly solved because inducing current directly affects programmable logic controller (PLC) (PLC) system, make to allow to drive to play the safety control effect.
Description of drawings
Fig. 1 is the utility model scheme drawing;
Fig. 2 is prior art electric-control system scheme drawing;
Fig. 3 is the intermediate relay circuit diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, 2, a kind of Electric Control System of Mine Hoister at first is together in series the permission switch on the hole top signal platform, allows access air switch ZK between switch circuit series and the power supply in each stage casing, down-hole.Because when extraordinary circumstances occur in the down-hole, such as faults such as electric leakage, short circuits, can turn off air switch ZK, breaking is transported to the power supply of down-hole, and fault is not directly exerted an influence to programmable logic controller (PLC) (PLC) system.Allow to increase by an intermediate relay 1 between switch circuit series and programmable logic controller (PLC) (PLC) the cabinet module input mouth at the hole top signal platform, the model of intermediate relay 1 is JZ7 5A.Intermediate relay 1 is installed in the hole top signal platform, and independent current source and switch are set, and down-hole electric part and programmable logic controller (PLC) (PLC) system is disconnected fully.According to shown in Figure 3, connect with intermediate relay 1 normal the battle allowing switch on the hole top signal platform, be input to input port (00302) in programmable logic controller (PLC) (PLC) system, make this input port (00302) carry out work according to signalman's instruction.If down-hole part et out of order, can break and be transported to the power supply of down-hole, intermediate relay 1 normal the battle carried out short circuit, input port (00302) only has permission switch control on the hole top signal platform, it doesn't matter with downhole system, the all right normal operation of gig this moment is convenient to service personnel to the down-hole looking up the fault.Handle after the fault, system is recovered normal.
The utility model technology is the characteristics stronger according to the mine down-hole induction electricity, by allow to increase between switch circuit series and the input port structure of an intermediate relay 1 in the mouth signal bridge, not direct programmable logic controller (PLC) (PLC) system of inducing current is exerted an influence, stopped the possibility of post worker's maloperation, improved equipment service efficiency and safety performance, be mainly used in the underground signal system.
