Abstract
The utility model discloses an intelligent type multipoint displacement monitoring and early warning device which comprises a plurality of sets of in-hole fixed devices and an out-hole intelligent data processing terminal; according to the in-hole fixed devices, tension springs are arranged on an anchor blocks, and the anchor blocks are connected with the tension springs through steel wires; the out-hole intelligent data processing terminal consists of a piezoresistor, an intelligent data processor, a display screen, a storage and an early warning module which are electrically connected; the piezoresistor is connected with the tension spring of the corresponding in-hole fixed device; an electric signal generated by the piezoresistor is converted into a displacement signal through the intelligent data processor, the displacement signal is stored by the storage and displayed by the display screen, and the early warning module generates an early warning signal. The diameters of the anchor blocks are unnecessarily large, therefore, ordinary drilling equipment on the engineering field can meet the requirement on the conventional drilling diameter; furthermore, the early warning module is used for analyzing and judging whether the surrounding rock deformation looses stability, thus realizing the safety early warning function.
Description
Technical field
The utility model relates to country rock deep displacement monitoring device, is particularly useful for automatic monitoring and the safe early warning of mine working, highway and railway tunnel deep displacement.
Background technology
At present mine working and the conventional country rock deep displacement monitoring instrument of traffic tunnel have two kinds of mechanical type multiple-point displacement gage and intelligent multipoint displacement meters.Relevant with the application is intelligent multipoint displacement meter.Existing intelligent multipoint displacement meter is comprised of intelligent data processing terminal outside hole inner fixing device and hole; Because hole inner fixing device volume is large, installation requirement bore diameter is large, and (two point form requires bore diameter 60mm, more than bikini requires bore diameter 100mm), the on-the-spot boring apparatus of common engineering is difficult to meet the demands, and outside hole, intelligent data processing terminal does not have the function of safe early warning.
Utility model content
The purpose of this utility model is to provide a kind of intelligent multi-point displacement monitoring warning device that volume is little, easy for installation, have automatic monitoring and safety precaution function that has.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A multi-point displacement monitoring warning device, comprises intelligent data processing terminal outside many trepannings inner fixing device and hole; It is characterized in that, described hole inner fixing device is comprised of anchor block, wire and tension spring, and anchor block is provided with tension spring, and anchor block is connected with tension spring by wire; Outside described hole, intelligent data processing terminal is electrically connected and is formed by voltage dependent resistor (VDR), intelligent data processor, display screen, storer and warning module; The number of voltage dependent resistor (VDR) equates with the tricks of hole inner fixing device, and voltage dependent resistor (VDR) is connected on the tension spring of respective aperture inner fixing device; The electric signal that voltage dependent resistor (VDR) produces is converted into displacement signal by intelligent data processor, and displacement signal shows by memory stores and by display screen, and produces early warning signal by warning module.
In order to protect tension spring, at tension spring, be provided with sleeve pipe outward, sleeve outer wall border is provided with tension spring, by tension spring, sleeve pipe is clamped on the aperture of boring.
The tricks of above-mentioned hole inner fixing device is counted and is determined according to each boring country rock of surveying.
During use, in tunnel or the inner key position of tunnel surrounding set the boring of certain depth, anchor block is pushed to the different depth of boring successively, by the tension spring on anchor block, be stuck on boring country rock wall, and by manually wire being applied to certain power, anchor block and the wall of a borehole are combined closely; Taut wire line is also connected with tension spring separately; The tension spring that intelligent data processing terminal outside hole is fixed on to Wai，Jiang hole, hole inner fixing device is connected with the voltage dependent resistor (VDR) of intelligent data processing terminal outside hole.After connection, carry out primary data zero clearing, distortion early warning value is set simultaneously.
Principle of work of the present utility model is: when country rock stress state variation produces displacement, anchor block is along with country rock synchronizing moving, the surrounding rock displacement at different depth place changes different, thereby cause each tension spring of aperture that elongation in various degree occurs, cause each voltage dependent resistor (VDR) that different variations occurs, export different electric signal, realize the conversion of displacement → power → electric signal, IDT is realized the conversion of electric signal → displacement by plug-in, and shift value is outputed on display screen, store data simultaneously, and realize security early-warning analysis by warning module.
The utility model has the advantages that: because anchor block diameter does not need too slightly, so can adopt conventional bore diameter, the on-the-spot boring apparatus of common engineering just can meet the demands; But also can judge whether unstability of surrouding rock deformation by warning module analysis, realize the function of safe early warning.
