Abstract
The utility model provides a jacking warning indicator of a self-dumping car, which comprises a non-contact type proximity switch SQ, a relay KA1, a relay KA2, a work indicating light L1, an alarm lamp L2 and an alarm electric bell DL, wherein, a power supply is divided into three ways from a positive pole, one way returns to the negative pole of the power supply after passing through the non-contact type proximity switch SQ and a relay KA1 coil, the two ends of the relay KA1 coil are connected in parallel with the work indicating light L1; another way returns to the negative pole of the power supply after passing through a normally-closed contact point KA1a of the relay KA1 and the relay KA2 coil; the third way returns to the negative pole of the power supply after passing through a normally-opened contact point KA2a of the relay KA2 and the alarm lamp L2, and the two ends of the alarm lamp L2 are connected in parallel with the alarm electric bell DL. The utility model can be widely applied to the self-dumping car in a mining enterprise and other vehicles with lifting devices.
Description
Technical field
The utility model relates to a kind of warning indicating device, relates in particular to a kind of top lifting warning indicating device that is used for self clearing car.
Background technology
In mining industry is produced, because the frequent descending operation of mine car easily causes oil controlling valve to damage, maloperation takes place easily, promptly rise automatically on the oil top.Under steam, if the driver can not find in time that oily jacking rises and with its landing compartment, abnormally dangerous in then advancing, be easy to cause equipment to scratch, even more dangerous accident, bring loss and painful for company and individual, take place for fear of such accident, design this control device.
The utility model content
The technical problems to be solved in the utility model is: design and a kind ofly solve that warning indication, circuit after the self clearing car non-artificial operation in oil top is in the process of moving risen is simple, reliable operation, expense be low, easy to maintenance, the self-dumping car top lifting warning indicating device that can work under rugged environment.
The technical solution of the utility model is: a kind of self-dumping car top lifting warning indicating device, it is characterized in that: comprise non-contact type approach switch SQ, relay K A1, relay K A2, relay indicating light L1, alarm lamp L2 and warning electric bell DL, the mine car power supply is divided into three the tunnel from positive pole, one the tunnel gets back to power cathode behind described non-contact type approach switch SQ, relay K A1 coil, be parallel with relay indicating light L1 at the two ends of relay K A1 coil; Power cathode is got back in another road behind the normally closed contact KA1a of described relay K A1, relay K A2 coil; Third Road is got back to power cathode behind normal opened contact KA2a, the alarm lamp L2 of described relay K A2, be parallel with warning electric bell DL at the two ends of alarm lamp L2.
The utility model has following advantage compared with the prior art:
1, simple, the reliable operation, easy to maintenance of the utility model circuit.
2, the electrical equipment work of the utility model employing is not subjected to the influence of mine dust, can work under rugged environment.
Description of drawings
Fig. 1 is an electric control circuit schematic diagram of the present utility model;
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In Fig. 1 electric control circuit schematic diagram of the present utility model, self-dumping car top lifting warning indicating device comprises non-contact type approach switch SQ, relay K A1, relay K A2, relay indicating light L1, alarm lamp L2 and warning electric bell DL, power supply is divided into three the tunnel from positive pole, one the tunnel gets back to power cathode behind described non-contact type approach switch SQ, relay K A1 coil, be parallel with relay indicating light L1 at the two ends of relay K A1 coil; Power cathode is got back in another road behind the normally closed contact KA1a of described relay K A1, relay K A2 coil; Third Road is got back to power cathode behind normal opened contact KA2a, the alarm lamp L2 of described relay K A2, be parallel with warning electric bell DL at the two ends of alarm lamp L2.
The workflow of self-dumping car top lifting warning indicating device is as follows: whether non-contact type approach switch SQ is installed between the big frame in mine car compartment and oil top, be used to detect the compartment and separate with big frame; Under the normal condition, the oil top is positioned at the mine car compartment, non-contact type approach switch SQ closure, relay K A1 coil is charged, and its normally closed contact KA1a disconnects, and relay K A2 coil is not charged, relay K A2 normal opened contact KA2a disconnects, alarm lamp L2 and warning electric bell DL are not charged, near switch S Q relay indicating light L1 Chang Liang, indicate working properly near switch S Q; When mine car under steam, when rose unusually on the oil top, non-contact type approach switch SQ opened the contact, relay K A1 dead electricity, its normally closed contact KA1a closure, relay K A2 coil is charged, relay K A2 normal opened contact KA2a closure, and alarm lamp L2 and warning electric bell DL are charged, send sound and light alarm, the prompting unusual automatic rise in driver oil top, thus supervise the driver to check and with in the safe falling compartment, oily top, thus avoid the generation of scratch accident.
Non-contact type approach switch SQ can adopt commercially available inductance type or capacitive approach switch series of products, wherein inductance approach switch belongs to a kind of position transducer that switching value output is arranged, it is made up of LC high frequency oscillator and amplification treatment circuit, utilize metal object when the vibration inductive head that can generate an electromagnetic field, make interior of articles produce eddy current near this.This eddy current reacts near switch, makes near the decay of switch vibration ability, and the parameter of internal circuit changes, identify thus to have or not metal object approaching, and then the on-off of gauge tap.Capacitive approach switch also belongs to a kind of position transducer with switching value output, its measuring head normally constitutes a pole plate of capacitor, and another pole plate is object itself, when object is shifted near switch, object and change near the specific inductive capacity of switch, make the circuit state link to each other with measuring head also change, thus just turning on and off of controllable switch thereupon.
Relay indicating light L1 was bright when non-contact type approach switch SQ was working properly, and when non-contact type approach switch SQ dead electricity or when damaging, relay indicating light L1 extinguishes, thereby can remind driver's not operate as normal of indicating device of reporting to the police.
Self-dumping car top lifting warning indicating device can adopt the mine car DC power supply, and as 24 volts or 36 volt-amperes of full voltages, other element running parameter of corresponding selection gets final product.When the self-dumping car normal operation, excise this warning indicating device power supply, and in operation end mine car cruising process, only need to drop into this warning indicating device power supply, device gets final product operate as normal.
The safeguard protection that the utility model can be widely used in the self-dumping car of mining firm and have other vehicle of jacking equipment.
