Description of drawings
Below in conjunction with embodiment and accompanying drawing thereof the utility model is elaborated.
Fig. 1 is the circuit structure diagram according to the long-range power-down control device of shuttle car of embodiment of the present utility model.
Embodiment
According to embodiment of the present utility model, as shown in Figure 1, wherein the long-range power-down control device of shuttle car illustrates with empty collimation mark, as can be seen from the figure, the long-range power-down control device of shuttle car mainly comprises contact switch, rectifier bridge 5, the coil 6 of vacuum contactor and the contact switch 7 of vacuum contactor of intrinsic safety isolated gate 2, explosion-proof travel switch 3, the coil 4 of first conductance relay, first conductance relay.The long-range power-down control device of shuttle car in the utility model is connected to shuttle car by internal transformer and provides on the power lead of operating voltage, be 2 power supplies of intrinsic safety isolated gate, explosion-proof travel switch 3 is connected on this branch road with the coil 4 of first conductance relay, rectifier bridge 5 is arranged on another branch road in parallel with this branch road, by the work of rectifier bridge 5 output voltages control vacuum contactor.In this embodiment, coil 4 controls of first conductance relay are arranged on the contact switch XJ1 of the first conductance relay of rectifier bridge 5 place branch roads, and coil 6 controls of vacuum contactor are arranged on the contact switch 7 of the vacuum contactor on the shuttle car power supply branch road.That is to say that first conductance relay can be controlled the break-make of vacuum contactor, then the break-make of vacuum contactor can be controlled the break-make to the power supply of shuttle car.
To some parts that wherein relate to be briefly described below.Intrinsic safety isolated gate 2 refers to mining essential safe type isolated gate.Isolated gate is isolated amplifier, and major function is that input signal is nursed one's health, and isolates the corresponding output signal of output.Usually; here said isolated amplifier relates to the amplifier of electric insulation between a kind of input circuit and the output circuit, and its effect is that simulating signal is isolated, and amplifies according to a certain percentage; thereby the raising common-mode rejection ratio is protected electronic equipment and personal safety simultaneously.In the process of isolating, amplifying, need to guarantee that the distorted signals of output is little, so the linearity, precision, bandwidth, isolation is withstand voltage etc., and parameter all will reach request for utilization.Explosion-proof travel switch 3, it is the position switch, be also referred to as limit switch, be a kind of little electric current master control electrical apparatus commonly used (be used for connect and disjunction control circuit make programme controlled device for switching with issue an order or to production run), it utilizes the collision of manufacturing machine moving component to make its contact move to realize to connect or the disjunction control circuit, reaches certain control purpose.Usually, this class switch is used to position or the stroke of limit mechanical motion, make moving component by certain position or stroke stop automatically, counter motion, variable motion or back and forth movement etc. automatically, be used for stroke and the position limitation protection of control plant equipment.In real work, explosion-proof travel switch 3 can be installed in ad-hoc location in advance.In the present embodiment, explosion-proof travel switch 3 is installed in caution fence (being used for intercepting workplace and tunnel).When the bump of the module on the mechanical moving element that is installed in caution fence explosion-proof travel switch 3, the contact action of explosion-proof travel switch 3 realizes the switching of circuit.Therefore, travel switch is a kind of travel position according to moving component and the electrical equipment of commutation circuit, and its action principle and button are similar.Vacuum contactor utilizes the vacuum interrupter arc extinguishing, in order to frequent connection with cut off running current, in being generally used for switching on and off at a distance, 6kV, 380V (660V, the 1140V) AC motor of the frequent start-stop of low pressure.In this embodiment, vacuum contactor can adopt the contactor of the reprinting functional loop of a car of through transport, in actual use, reprints function and does not use, and therefore, in this embodiment this loop is used to the shuttle car power supply.
Principle of work below in conjunction with the long-range power-down control device of shuttle car in the utility model of embodiment describes.In this embodiment, first conductance relay and vacuum contactor are flame-proof switch open in usual, and first conductance relay is optional uses mining leakage relay.Under the normal operating conditions of the long-range power-down control device of shuttle car, when the operating personnel that taking a car of through transport need enter workplace in the tunnel, open as long as will warn fence, then explosion-proof travel switch 3 disconnects, thus, coil 4 dead electricity of elder generation's conductance relay, then make contact switch XJ1 disconnect, be connected rectifier bridge 5 outages of this branch road so, coil 6 outages of vacuum contactor thus, impel its contact switch 7 to disconnect, then stop the shuttle car power supply, shuttle car is out of service then.Fence will be opened and locking as long as will warn, and make explosion-proof travel switch 3 remain in open mode, and shuttle car just keeps off-position always, thereby assurance enters the operating personnel's of workplace personal safety.When operating personnel finish corresponding work, the caution fence can be shut, utilize mechanical chain, explosion-proof travel switch 3 closures, the coil 4 of elder generation's conductance relay, make its contact switch XJ1 closure, thereby rectifier bridge 5, the output direct current is to coil 6 two ends of vacuum contactor, coil 6 electric after, contact switch 7 closures of the vacuum contactor on car of control through transport, (for example 1140V) will power to shuttle car in supply line so, make shuttle car be in normal operating conditions again, continue operation.
The long-range power-down control device of shuttle car provided by the utility model has following characteristics:
1, whole device is realized the control of low pressure intrinsic safety, utilizes explosion-proof travel switch, more strengthens security and reliability, meets the mine safety standard.
2, electric elements are less, simple in structure in the total system, avoided many, the mobile inconvenient difficult problems of equipment of using feed to cause.
3, reasonable in design, can cut off the power supply, guarantee safety by efficient remote control shuttle car.
4, effectively utilized existing equipment vacant components and parts, improved plant factor, cost low, be convenient to promote.
5, practical, can be in time long-range with the shuttle car dump, fundamentally solve a safety management difficult problem.
Although the utility model is to be described by the mode of reference accompanying drawing with above-mentioned preferred embodiment, be appreciated that way of realization of the present utility model is not limited to above-mentioned embodiment.For example alternatively, in space, non-down-hole, can install feed, by the outage of feed control shuttle car.Should be realized that in not deviating from the utility model claim scope required for protection, those skilled in the art can make multiple different variation and adjustment to the utility model.
