Description
Technical field
The utility model is related to coal mine safety monitoring equipment, particularly a kind of dress of portable monitoring fall of ground hidden danger
Put.
Background technology
Fall of ground is one of major security risk of China's coal-mine safety in production, once occurring, can cause huge people
Member's injures and deaths and economic loss.A key factor for causing colliery roof collapse disaster is exactly that back has absciss layer phenomenon, also
Be in roof strata below rock stratum lose and contact with rock stratum above, finally develop into completely falling off, roof fall.Tunneling
Due to roof strata absciss layer information can not be directly obtained in journey, so that supporting measure can not be taken in advance, roof fall accident is caused.
During tunnelling, in order to prevent mainly using roof separation indicator on the generation of roof fall accident, current colliery
To monitor, in testing at the scene, roof separation indicator is to pass through multiple fixing devices in roof hole with the value of formation variations to measure
Steel wire rope reflection is to being located on the survey reading plotter of top board surface, by the displacement difference of top plate different layers position, judges that tunnel is pushed up
The stability of plate and the supporting effect in tunnel.In whole process, due to the having differences property of setting of drilling, the manual work of miner
Industry has the influence of human factor, so as to can not accurately judge the supporting effect of butt entry roof.
Before tunnel working face men working excavation, roof fall hidden danger is also investigated by some measures, miner uses one
Stock is tapped to the rock mass of top plate and both sides, so as to exclude roof fall hidden danger, and custom is referred to as tapping, this is also due to pair
Top plate hidden danger monitors a kind of inaccurate remedial measure, and there is also risk.
Based on problem above, it is necessary to research and develop it is a kind of it is new tap device, test is carried out whenever and wherever possible, to the greatest extent may be used
All positions can be spread to there is provided reliable roof delamination data, inspection and management to roadway construction quality ensure construction peace
Entirely, but so far there are no is publicly reported.
Utility model content
For above-mentioned situation, to overcome the defect of prior art, the purpose of the utility model is just to provide a kind of portable
The device of fall of ground hidden danger is monitored, can effectively solve to monitor fall of ground hidden danger, it is ensured that the problem of production safety.
The technical scheme that the utility model is solved is, including handle, display and supersonic generator, the hollow cavity of handle
It is equipped with vivo on power supply, supersonic generator and controller, handle outer wall and display, the front end of handle and the rear end of pull bar is housed
It is connected, the front end of pull bar is equipped with the antenna for receiving and dispatching, handle outer wall top is equipped with alarm lamp（Also buzzer report can be used
It is alert）, power end of the power supply respectively with display, supersonic generator be connected, controller respectively through wire and Explosion proof joint with it is aobvious
Show that device, supersonic generator and antenna are connected, alarm lamp is connected with controller, electricity of the power supply through wire and on housing
Source switch is connected with the power end of controller.
The utility model is simple in construction, novel and unique, carries easy to use, effect is good, can be effectively used for monitoring tunnel and emits
Push up hidden danger, it is ensured that coal mine production safety, there is good economic and social benefit.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model（Partly cut-away）.
Embodiment
