Abstract
The utility model discloses a device for monitoring and early warning roof fall of a roadway, which is mainly used for monitoring and early warning the roof fall of the roadway, and comprises a bolt-anchor tension sensor, a displacement sensor and a secondary meter. The bolt-anchor tension sensor can be used for monitoring tension states of a bolt and an anchor in real time through the secondary meter; the displacement sensor can be used for monitoring bed separation situations of a roof layer in real time through the secondary meter; and the secondary meter is shared by the two sensors, is used for acquiring and storing signals transmitted by the sensors and displaying monitoring data in real time, and has a sound and light alarm function. According to the device, the tension states of the bolt and the anchor and the bed separation situations of the roof layer are monitored in real time, and the monitored data is analyzed and operated, so that the hidden danger of the roof fall of the roadway is recognized; and when the hidden danger of the roof fall is found, the device for monitoring and early warning the roof fall of the roadway can give an sound and light alarm.

The utility model solves the technical scheme that its technical matters adopted:
A kind of tunnel roof fall monitoring and warning appearance comprises anchor shaft anchor cable pulling force sensor, displacement transducer, secondary instrument, the shared secondary instrument of anchor shaft anchor cable pulling force sensor and displacement transducer.Secondary instrument is gathered, is stored the information that each sensor transmits, and shows Monitoring Data in real time, and has sound and light of alarm.
A kind of tunnel roof fall monitoring and warning appearance simultaneously to roadway roof absciss layer value and stressed big or small two association of anchor shaft anchor cable gather, store, analysis, computing, specific targets comprise the stressed size of rate of change, anchor shaft anchor cable of the stressed threshold value of anchor shaft anchor cable, roof delamination amount threshold value, the stressed size of anchor shaft anchor cable and roof delamination amount and frequent degree that the roof delamination amount is undergone mutation etc.
Secondary instrument mainly contains wiring board, shell, plug interface etc.; Wiring board comprises single-chip microcomputer, storer, demonstration special chip, special clock chip and periphery circuit; The input end of single-chip microcomputer is connected with anchor shaft anchor cable pulling force sensor, displacement transducer, the corresponding respectively corresponding end that shows special chip that is connected to of the nucleus module output terminal of single-chip microcomputer.
Displacement transducer is provided with a plurality of displacement basic points at the top board different depth, and is provided with special-purpose displacement amplification device, monitors the roof delamination situation in real time through secondary instrument.
The anchor shaft anchor cable pulling force sensor is monitored the stressed variation of anchor shaft anchor cable in real time through secondary instrument.
The beneficial effect of the utility model:
This kind tunnel roof fall monitoring and warning appearance through simultaneously to roadway roof absciss layer value and stressed big or small two association of anchor shaft anchor cable gather, store, analysis, computing discern tunnel roof fall hidden danger; When finding roof fall hidden danger, carry out sound and light alarm, improved the reliability of tunnel roof fall monitoring and early warning greatly.
2. anchor shaft anchor cable pulling force sensor and displacement transducer simultaneously to roadway roof absciss layer with anchor shaft anchor cable is stressed monitors in real time, and with data automatic recording, can be understood anchor shaft anchor cable supporting situation and top board condition through secondary instrument preferably.
3. its said displacement transducer is provided with a plurality of displacement basic points at the top board different depth, and is provided with displacement amplification device, has improved the degree of accuracy of roof delamination monitoring, has enlarged the top board monitoring range, the real-time monitoring of more convenient realization top board displacement.
Description of drawings
When combining accompanying drawing to consider; Through with reference to following detailed, can more completely understand the utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide the further understanding to the utility model; Constitute the part of the utility model; Illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model, wherein:
