Description
Technical field
The utility model relates to monitoring equipment, particularly a kind ofly is used for stroke and the hydraulic pressure value that resource exploitation process stope mine pressure monitor is monitored hydraulic support.
Background technology
Coal-face safety is the important component part of Safety of Coal Mine Production, and therefore the reliability of hydraulic support, improves the support reliability through hydraulic support pressure and stroke monitoring and seem particularly important for the work plane conclusive effect of having kept the safety in production.Coal mining enterprise mainly uses pointer detector and resistance-type detector now, and the suffered hydraulic pressure value of hydraulic support is detected the good effect of having played.
But pointer detector prohibited data detection is true, and it is imperfect to detect content, lacks storage analytic function and warning system; The resistance-type detector lacks warning system equally, and the instrument volume is bigger, uses complicacy, poor stability.Therefore, it is little, simple to operate to design a kind of volume, and possesses the hydraulic support detector of storage analysis and warning system and important.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of stope mine pressure monitor, can possess the function of storage analysis and warning.
The stope mine pressure monitor of the utility model; Comprise measuring instrument, hydrostatic sensor and displacement transducer; Said measuring instrument links to each other with displacement transducer with hydrostatic sensor respectively; Wherein, said hydrostatic sensor is installed on the hydraulic valve of hydraulic support, and said displacement transducer is fixed on the hydraulic support.
Wherein, Be provided with data acquisition unit and data processing unit in the said monitor; Said data acquisition unit is connected with said data processing unit; To data processing unit, whether said data processing unit carries out analyzing and processing according to hydrostatic sensor and displacement transducer sensing signal safe and reliable to confirm hydraulic support with the hydrostatic sensor that collects and displacement transducer sensing signal transmission for said data acquisition unit.
Wherein, In said monitor; Further be provided with data passes unit and display unit; Said data passes unit is connected with said display unit, and said data passes unit is connected with said data processing unit, and said data passes unit will be passed to said display unit through hydraulic pressure value and the stroke that said data processing unit is analyzed gained and show.
Further, said display unit is arranged on the said monitor or separates with said monitor.
In addition, said measuring instrument can further be connected with anchor pole (rope) pulling force sensor, and the data acquisition unit in the said measuring instrument is gathered anchor pole (rope) pulling force of said anchor pole (rope) pulling force sensor sensing.
Further, said displacement transducer is arranged in the measuring instrument or with said measuring instrument and separates setting.
The beneficial effect of the utility model is: according to the stope mine pressure monitor of the utility model; Through measuring instrument is linked to each other with displacement transducer with hydrostatic sensor respectively; Whether thereby it is safe and reliable to confirm hydraulic support to carry out analyzing and processing according to the signal that hydrostatic sensor and displacement transducer sense; This monitor possesses the function of storage analysis and warning system, and volume is little, and is simple to operate.
