Abstract
The utility model relates to a position sensor for stringing electric locomotive, comprising an electromagnet, a Hall switching element, and an amplifying circuit, wherein, the amplifying circuit has the property of delayed release. The power source of the electromagnet is supplied by that a contact line passes through the pantograph of an electric locomotive, auxiliary conductors, and a resistor for stopping currents. The power of electromagnet coils is switched on when the pantograph of the electric locomotive contacts with the auxiliary conductors, a magnetic field is generated, the Hall switching element transmits signals, a relay moves after the signals are magnified, the signals are transmitted by contact points, high levels can also be transmitted by collecting electrodes of a triode, and the signals which are transmitted are delayed. The sensor has the advantages that the sensitivity is high, motions are reliable, and the auxiliary conductors are short.
Description
The utility model is a kind of sensor of measuring the stringing electrical locomotive position.
The sensor of present this purposes, formal manufacturer production mainly contain two kinds: a kind of is auxiliary traverse formula sensor, and another kind is an infrared ray sensor.
With in parallel with capacitor again after relay is connected, the other end of resistance is connected with auxiliary traverse auxiliary traverse formula sensor by resistance, and the other end of relay is connected with rail.Auxiliary traverse is fixed by bolts on the support by the embowment of band steel, with insulating clamp support is installed on the osculatory of powering into electric locomotive again.Do not have electricity on the auxiliary traverse at ordinary times, when the electric locomotive pantograph contacted with it, the voltage on the osculatory promptly was added on the relay coil actuating of relay by pantograph, auxiliary traverse after the resistance step-down; Auxiliary traverse is when sending electricity to relay, also to the capacitor charging, when the electric locomotive pantograph was left auxiliary traverse, capacitor discharged to relay through resistance, makes its slow putting.The shortcoming of auxiliary traverse formula sensor is low, the slow motion of sensitivity, when the electric locomotive travelling speed is too fast, the tripping situation can appear once in a while, reason is that used here relay all is 110 volts or 220 volts of relays, coil turn is many, inductance is big, the starting time is long, another shortcoming is that used auxiliary traverse is not only grown but also heavy, and general length is at 1.0～1.3 meters.
Infrared ray sensor in type approval test, the not high problem of reliability also occurred recently, and analyzing its reason is that temperature height and trickle cause owing to coal dust under the coal mine is big.Coal dust might luminophor or photoreceptor covers or part covers, and water has absorption to infrared ray.
The purpose of this utility model provides a kind of highly sensitive, reliable in action, can be used for the stringing electrical locomotive position transducer of rugged surroundings under the coal mine.
Task of the present utility model realizes as follows: press polar requirement at the intensive place of magnetic flux of electromagnet and place the Hall switch element, the pin 1 of Hall switch element connects positive-negative-positive transistor emitter and positive source, pin 3 connects the base stage of triode by resistance R b, pin 2 ground connection also connect the collector plate of triode by relay and diode, are connecting capacitor between A ', the B ' of circuit point or between B ', C ' point.Electromagnet connects power supply through current-limiting resistance, auxiliary traverse, electric locomotive pantograph and osculatory.Auxiliary traverse is made up of soft resilient conductor, support and insulating clamp, there is not electricity at ordinary times when the electric locomotive pantograph contacts with it, be about to the power supply on the osculatory, pass to electromagnet coils through current-limiting resistance, electromagnet produces magnetic field makes the Hall switch element send signal, makes the triode conducting, the actuating of relay after amplifying circuit amplifies, by its contact output signal, also can be from the collector output high level V of triode
o
The sensor that the utility model provides, the electromagnet coils number of turn is few, electric current is little, self-induced e.m.f is little during energized, the starting time short, highly sensitive, reliable in action, and auxiliary traverse can shorten.
Below in conjunction with accompanying drawing the utility model is done further narration.
Fig. 1 is embodiment circuit theory diagrams of the utility model.
Fig. 2 is another embodiment circuit theory diagrams.
Fig. 3 is another delay circuit figure among the embodiment.
In Fig. 1, Fig. 2,250 volts or 550 volts of DC voltage are arranged on the osculatory (7), auxiliary traverse (8) is fixed by bolts on the support by after soft, the resilient conductor embowment, with insulating clamp support is installed on the osculatory (7) again, does not have at ordinary times; Resistance (9) one ends connect auxiliary traverse (8), and the other end connects an end and the diode D of electromagnet coils
1Negative pole, the electromagnet coils other end connects diode D
1Positive pole and rail 10; Electromagnet (4) is made up of coil and soft magnetic material, and Hall switch element (5) is installed in by polar requirement in the slit of soft magnetic material or near the end of soft magnetic material and installs; The pin 1 of Hall switch element (5) connects emitter and the positive source of positive-negative-positive triode BG1, and pin 3 connects the base stage of BG1 by resistance R b, and pin 2 ground connection are connected relay J and diode D between the collector of BG1 and the ground
2, these several elements connect to form amplifying circuit (6); The time-delay release performance of amplifying circuit realizes that by the capacitor C that A ', B ' point-to-point transmission connect capacitor C also can be connected B ', C ' point-to-point transmission; Amplifying circuit adopts 6～24 volts of D.C. regulated power supplies.
In Fig. 3, relay tip J(11), (13) are back contact, J(11), (12) are normally opened contact, J(12) connect B ' point, J(11) connect the capacitor C positive pole, J(13) connect capacitor C negative pole and C ' point, B ' point, C ' point link to each other with B ' point, the C ' point of amplifying circuit respectively, constitute another kind of delay releasing circuit.
When electric locomotive pantograph and auxiliary traverse (8) when contacting, power supply on the osculatory (7) is passed to the coil of electromagnet (4) after resistance (9) current limliting, electromagnet produces magnetic field, make Hall switch element (5) send signal, amplify BG1 conducting, relay J action through amplifying circuit (6), by its contact output signal, also can be by the collector output high level V of BG1
oResistance R b be the base resistance of BG1 be again the current-limiting resistance of Hall switch element (5).With electromagnet coils diode connected in parallel D
1Effect be when coil blackout, for the electric current in the coil provides path, protective resistance (9); In like manner, D
2Protection BG1.
With reference to Fig. 2, before use, being connected on the capacitor C of circuit B ', C ' point-to-point transmission does not have electric charge, when beginning to send electricity, can make BG1 conducting, the actuating of relay by BG1, Rb to the C charging because of power supply; In addition, behind long-term the power failure, because C slowly discharges, also above-mentioned situation can appear when recovering to send electricity, so this delay circuit only should be used in the amplifying circuit of reliable source of power.
With reference to Fig. 3, the delay circuit that is connected on B ', C ' point-to-point transmission produces time-delay after the actuating of relay, so only should be used in the amplifying circuit of high sensitive relay.
