The utility model discloses can realize the purpose of multiple index monitoring dead zone top bottom plate, simple structure, simple to operate can show the numerical value of displacement and pressure, again can be when reaching early warning value automatic alarm, realize the function of remote monitoring and record, the practicality is strong.
Description
Technical field
The utility model relates to mining area safety monitoring system, is specifically related to a kind of beacon dead zone line pressure shift monitor and alarm system can being monitored dead zone roof and floor pressure and displacement.
Background technology
Non-coal mine in recent years, particularly Gypsum Mine dead zone large area cave-in accident occurs repeatedly, and causes huge economy and personal casualty loss.The immediate cause producing disaster is the stress equilibrium that the mining activity of crossbeam destroys Rock in Well, when pressure reaches the support strength limit of rock, will occur crushing, the phenomenon such as floor projection, ore pillar fracture, can the caving in of occurrence of large-area when overstepping the extreme limit.
In conventional art, the monitoring method for dead zone uses timber wedge method, distance pole method and beacon method mostly, and beacon method utilizes rod etc. to be supported between the roof and floor of dead zone exactly, utilizes the deformation of rod to send signal to operating personnel.In prior art, though using rock noise instrument, dead zone roof and floor displacement monitor to a certain extent dead zone to be monitored, but function singleness, pressure can not be measured with displacement simultaneously.
Summary of the invention
The utility model is in order to solve original monitoring method insufficiency, the problem of warning effect difference, it is provided that a kind of technical ability pressure measurement also can displacement, and realize the beacon dead zone line pressure shift monitor and alarm system of multiple type of alarm.
The utility model realizes by the following technical solutions, beacon dead zone line pressure shift monitor and alarm system, including being arranged on the cylinder of scalable fixing beacon between top board and base plate, the lower section of cylinder is provided with support means, cylinder is connected with support means elasticity, being provided with the display device reading displacement between cylinder and support means, elastic joint part is provided with adjusting means, and display device connects alarm.
Observing for convenience and report to the police, described display device is spring measurement device, and pogo barrel is provided with pointer and scale, is provided with the travel switch triggering alarm outside pogo barrel upper end.
In order to regulate spring range and reset, the lower section of described spring measurement device is provided with adjusting screw rod.
In order to realize monitoring more accurately, described display device is to use the electronic monitor system of electronic devices and components.
Of the present utility model it is beneficial in that, it is possible to realize the purpose of many indexes monitoring dead zone roof and floor, simple in construction, easy for installation, can show the numerical value of displacement and pressure, again can when reaching early warning value automatic alarm, realize the function of remotely monitoring and record, practical.
