Description
Technical field
The utility model relates to a kind of alarm, is a kind of alarm that is used for the mine hydraulic support pressure detection, is specially adapted to hydraulic support pressure detection alarm in the comprehensive mechanical coal mining operation.
Background technology
At present, strengthen the technological transformation of middle and small scale coal mine energetically along with China, comprehensive mechanical coal mining has obtained using widely, still, because middle and small scale coal mine all is local and private colliery, technical foundation is relatively poor relatively, the monitoring consciousness weakness is pressed in the ore deposit, and is not tight to first support, the control of maximum allowable working hydraulic pressure of fully mechanized mining supporter, makes bracket support efficient, top board safeguard relatively poor, even, cause roof accident because setting load is not enough, old rostellum is so pressed and prepared deficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and providing a kind of can monitor at any time according to the support of mines applicable cases, and accomplishes the comprehensive mining hydraulic bracket pressure detection alarm of sound and light alarm.
The purpose of this utility model can realize by following technical scheme:
Comprehensive mining hydraulic bracket pressure detection alarm, by isolating switch, the pressure digital displaying meter, pressure transducer, the sound and light alarm lamp, illuminating lamp is formed, one end and the external power source of its isolating switch link, the other end of isolating switch cut-in pressure digital displaying meter in parallel, two sound and light alarm lamps and a plurality of illuminating lamp, pressure transducer and pressure digital displaying meter link, the two ends of the warning output upper limit contact of pressure digital displaying meter are connected in series with a sound and light alarm lamp, the two ends of the warning bottoming contact of pressure digital displaying meter are connected in series with another sound and light alarm lamp, and each illuminating lamp all is connected in series with a luminous lamp switch.Isolating switch, pressure digital displaying meter, pressure transducer, sound and light alarm lamp and illuminating lamp are explosion-proof type.
Principle of work of the present utility model is as follows:
Use the explosion-proof type pressure transducer as pressure detecting element, pressure transducer is installed on the hydraulic support column, the power supply of pressure transducer is taken from explosion-proof type pressure digital displaying meter, the pressure signal that detects directly is sent to explosion-proof type pressure digital displaying meter in real time, promptly show the real-time pressure value, when pressure was greater than or less than setting, explosion-proof type was counted pressure and is shown instrument warning contact (upper limit contact or lower limit contact) closure, make sound and light alarm lamp energising work, note with the caution operating personnel.
Native system has illumination functions, uses explosion-proof type light switch and lighting, is connected in the alarm electric power loop, and switch and lighting are installed on the hydraulic support and (are installed in parallel a plurality of illuminating lamps on a plurality of hydraulic supports).
The major function of the utility model alarm is as follows:
1, old top first weighting, top board rock burst are caused support working hydraulic pressure UHV (ultra-high voltage), carry out with monitoring at any time, and accomplish sound and light alarm.
2, to stent support setting load little (even not connecing the top), the support working hydraulic pressure ultralow pressure that causes is monitored at any time, and is accomplished sound and light alarm.
3, to face roof ore deposit pressure, bracket support intensity, monitor at any time, and accomplish that numeral shows.
4, workplace is thrown light on, realize the bright exploitation in down-hole.
The utility model compared with prior art has following advantage:
1, can monitor at any time according to the support of mines applicable cases effectively, and accomplish sound and light alarm; Can effectively prevent support working hydraulic pressure superelevation or the ultralow security incident that causes.
2, switch and lighting are installed on the hydraulic support workplace are thrown light on, and realize the bright exploitation in down-hole, also can effectively prevent the generation of security incident.
