Description
Technical field
The invention belongs to technical field of engineering machinery, be specifically related to a kind of test unit of comprehensive protection device of Strap Transporter in Coal Mine.
Background technology
Belt conveyer claims again belt feeder, is the main transportation equipment of current coal mine operation, is undertaking transportation tasks out such as the coal under coal mine, spoils.Due to complex geologic conditions under coal mine, tomography, rise and fall more frequently, cause the defeated machine fortune of belt coal difficulty.As also the phenomenons such as ribbon, sideslip can occur while running into variable slope segment, and cause transported coal or spoil to shed, affected normal transportation and production.
At present; in order to improve the protection to underground belt conveyor; a kind of integrated belt machine protector is set on belt feeder; the integrated belt machine protector has cycling start delay function, language alarm function, scram defencive function, also has the defencive functions such as coal position to belt feeder, smog, sideslip, temperature, speed.If but the integrated belt machine protector has damage or fault; it need be raised to ground from down-hole keeps in repair; for be raised to the well face keep in repair good after; but because of without condition restriction such as test units; ruuning situation after can not observing the integrated belt machine protector and repairing in real work, more impossible being installed to down-hole on belt feeder carried out actual test.Therefore, to quality and the reliability thereof of the maintenance of integrated belt machine protector, can't be identified.
Summary of the invention
The present invention will solve above-mentioned deficiency exactly, and a kind of check integrated belt machine protector repair quality and efficiency are provided, and the integrated belt machine protector testing table ensured safety in production.
In order to reach above-mentioned effect, the invention provides a kind of integrated belt machine protector testing table, comprise the testing table body, testing table body upper surface is provided with power switch, power light, described power switch, power light are connected to form power circuit by wire and power supply, described testing table body interior is provided with analog signal generator, and described analog signal generator bridge joint is on power circuit; Be parallel with respectively coal bit test unit, smoke test unit, sideslip test unit, humid test unit and speed trial unit on described power circuit.
The preferred version of such scheme is, described analog signal generator is the self-control pulse signal generator, and analog signal generator is provided with the adjusting knob of regulating electric impulse signal frequency size, and described adjusting knob is located at the upper surface of described testing table body.
The preferred version of such scheme is that described coal bit test unit, smoke test unit, sideslip test unit, humid test unit, speed trial unit are respectively equipped with coal bit test button, smoke test button, sideslip test button, humid test button, speed trial button; The output terminal of coal bit test unit, smoke test unit, sideslip test unit, humid test unit, the speed trial unit input end of the coal bit test pilot lamp corresponding with it, smoke test pilot lamp, sideslip test pilot lamp, humid test pilot lamp, speed trial pilot lamp respectively connects; Described test button and pilot lamp all are located at the upper surface of described testing table body.
This belt feeder protector testing table adopts safe voltage 36V Control of Voltage, is controlled the break-make of power supply by a power switch, and it is safe and reliable, and simple to operate; Belt feeder protector testing table upper surface horizontal direction is equipped with the test button and protection pilot lamp of power light, power knob, adjusting knob and coal position, smog, sideslip, temperature, speed, so arranges operation scientific and reasonable and convenient test.
Analog signal generator is the self-control pulse signal generator, economize on electricity pulse signal frequency size that its adjusting knob is adjustable.During detection, the belt feeder protector is electrically connected to testing table, presses power knob, its power light can be bright.As detect belt feeder protector speed protection when test; speed trial button in testing table and belt feeder protector speed protection key are pressed and switched on power; analog signal generator is simulated the belt conveyer roller rotational speed; and this electric impulse signal is offered to the belt feeder protector, make the belt feeder protector determine running status according to the size of speed.By adjusting knob, the electric impulse signal frequency is turned down, also just be equal to the belt feeder travelling speed and reduce.Now, the speed protection pilot lamp on the testing table body is long bright, and the speed protection pilot lamp on the belt feeder protector is also long bright simultaneously, after the self-insurance time delay, stops immediately.After off-test, the electric pulse adjusting knob is transferred to correct position, the simulating signal device just can be supplied with a normal electric impulse signal, and just cycling start has again so just realized the detection test of the speed protection of belt feeder protector.
Similar aforesaid operations, whether the various functions such as the protection of coal position, smog protection, sideslip protection, temperature protection that can detect the belt feeder protector is intact.
Certainly, if the belt feeder protector newly increases function, as emergency stop protection along the line, tearing tape protection, voice alarm function, testing table of the present invention also correspondingly increases cut-off test unit, tearing tape test unit, audio alert test unit etc.
Duty when the present invention can simulate the normal operation of belt feeder, situation in the time of also can simulating other emerged in operation faults, realize the conversion of coal position, smog, sideslip, temperature, speed protection function, but whether complete detection integrated belt machine protector is sensitive reliable when working and malfunction, solid foundation is provided to the rear Performance Detection of integrated belt machine protector maintenance; Improve integrated belt machine protector repair quality and efficiency.
