Description
Technical field
The utility model relates to a kind of mining safety equipment, especially relates to a kind of colliery with intrinsic safety type live post amount of contracting and hydraulic support pressure monitor
Background technology
Be faced with three the Nature disasters in traditional Safety of Coal Mine Production: gas explosion, top board roof fall, Shuitu go out.Wherein gas explosion is because of the huge property of its harm and the taking place frequently property of accident, and people know and pay attention to the most, and the control of water has also had breakthrough progress along with the appearance of drainaging scheme and high powered water pump.But the research of roof accident does not also catch up with the requirement of Safety of Coal Mine Production development far away, and now, most of colliery rests on machinery instrument measurement, the situation of manual record roof pressure, displacement the monitoring of top board
Summary of the invention
At above problem, the utility model provides a kind of colliery with intrinsic safety type live post amount of contracting and hydraulic support pressure monitor, and the utility model can be monitored hydraulic support live post amount of contracting and pressure in real time, can monitor the movement of roof rule more accurately; And can measure and write down support setting load, design and decision-making foundation are provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of colliery is with intrinsic safety type live post amount of contracting and hydraulic support pressure monitor, comprise housing, be provided with observation circuit in the housing, described observation circuit comprises power supply, signal processing circuit and single-chip microcomputer, be connected with change-over circuit and signal amplification circuit in turn with single-chip microcomputer, wherein be connected with at least one displacement transducer with change-over circuit, be connected with at least one pressure transducer with signal amplification circuit, pressure transducer is communicated with hydraulic oil pipe; Described single-chip microcomputer connects host computer through signal circuit.
Above-mentioned monitor, described pressure transducer are provided with two.
Above-mentioned monitor, described displacement transducer are provided with two.
Above-mentioned monitor is connected with display circuit with single-chip microcomputer.
The hydraulic support pressure transducer links by the hydraulic tube of rapid-acting coupling and tested device, the change in electric amount that foil gauge on the sensor is caused by fluid pressure generation change in resistance sends the monitor electronic section to, through signal amplify, the A/D conversion, show after handling by single-chip microcomputer, storage and information transmission.
Displacement transducer is used to measure the hydraulic prop post amount of contracting alive, and sensor links to each other with monitor by cable, directly displacement signal is converted to voltage signal and sends monitor to.

Embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
As shown in Figure 1, 2, a kind of colliery comprises housing 1 with intrinsic safety type post amount of contracting alive and hydraulic support pressure monitor, is provided with observation circuit in the housing 1, described observation circuit comprises single-chip microcomputer, is connected with signal processing circuit, display circuit, signal amplification circuit and A/D change-over circuit with single-chip microcomputer;
Be provided with two and be used to measure hydraulic support the live displacement transducer 3 of the post amount of contracting, two pressure transducers 2 that are used to measure a column pressure, wherein displacement transducer 3 links to each other with monitor by cable, directly displacement signal is converted to the single-chip microcomputer that voltage signal sends monitor to; Hydraulic support pressure transducer 2 links by the hydraulic tube of rapid-acting coupling and tested device, the change in electric amount that foil gauge on the sensor is caused by fluid pressure generation change in resistance sends electronic section to, through signal amplify, the A/D conversion, show after handling by single-chip microcomputer, storage and information transmission.The utility model can be realized liquid crystal display, the monitoring mode of two spot pressures, two displacement points.
Single-chip microcomputer transmits information through signal circuit: can dock portable collector through infrared communication; Also can connect substation, main website, host computer through bus communication, host computer is to the data processing that performs an analysis, so that provide design and decision-making foundation for stope comes pressure prediction forecast, face timbering design, the design of top coal caving drawing coal technology etc.
Using method: by oil pipe and rapid-acting coupling, pressure transducer 2 is linked to each other with hydraulic cavities, and determine fixed form as the case may be.The wire rope of the displacement transducer 3 of the post amount of contracting of living is fixed on post movable part alive, displacement transducer 3 body parts of the post amount of contracting of living are fixed on the non-movable part of post alive, drag the fastening card that tightens of tight wire rope, the displacement transducer 3 of the hydraulic support post amount of contracting alive connects with instrument by mining signal cable and waterproof aviation plug.As be the situation of combined network communication, by mining communication cable mine intrinsic safety type pressure monitoring substation is carried out bus with instrument and connect.And mine intrinsic safety type pressure monitoring substation is articulated on the rock pressure [in mine system for monitoring displacement by bus mode.This instrument is monitored hydraulic support pressure and the post amount of the contracting displacement situation of living in real time, uploads in real time, and pressure and displacement are forecast prediction.
