Embodiment:
With reference to figure, the utility model patent roadway surrounding rock displacement comprises brake cable pipe 4, displacement transfer line 5, back up pad 1, ring flange 2, displacement detecting appearance 6 from the face monitoring device.Brake cable pipe 4 one ends are fixed on the back up pad 1 through hollow bolt 3; Back up pad 1 is fixed on the crag of displacement to be measured; The other end of brake cable pipe 4 is fixed on the web joint 9 through hollow bolt 3, and web joint 9 is fixed on the displacement detecting appearance 6, and displacement transfer line 5 one ends are fixed in the rock stratum from opening lock 8 through petrosal foramen; The other end of displacement transfer line 5 passes the displacement sensing mechanism of back up pad 1, brake cable pipe 4, web joint 9 connection displacement detecting appearance, and web joint 9 is fixed on the housing of displacement detecting appearance 6;
The two ends of brake cable pipe 4 must closely be fixed on respectively on back up pad 1 and the web joint 9; Make its two ends receive displacement transfer line pulling force when extrusion internally, brake cable pipe 4 does not produce compression deformation, and tubing such as other metals that the also available compressive strength of brake cable pipe 4 is high and can appropriateness crooked or plastics replace.
Described displacement transfer line 5 is the stainless steel flexible cord; Displacement transfer line 5 one ends are fixed on opening certainly on the lock 8 in the petrosal foramen; Be fixed in the petrosal foramen in the rock stratum from opening lock 8; Displacement transfer line 5 places brake cable pipe 4, and displacement transfer line 5 other ends pass the displacement sensing mechanism that the web joint 9 that is fixed on the displacement detecting appearance 6 connects displacement detecting appearance 6, and top, tunnel, base plate and two help displacement to be delivered to the displacement converted mechanism of displacement detecting appearance 6 through brake cable pipe 4 and displacement transfer line 5 combined mechanisms;
Described back up pad 1 and the position mounting flange 2 of crag surface of contact corresponding to stepping brake spool 4, installing and locating sleeve pipe 10 on ring flange 2, the displacement transfer line 5 in the brake cable pipe 4 is through locating sleeve 10.
The utility model patent roadway surrounding rock displacement from the face monitoring device can back up pad be installed on tunnel top, the base plate, the country rock surface; One end of displacement transfer line is fixed in the rock stratum from opening lock through petrosal foramen; When back, base plate, country rock crag and rock stratum produce displacement; Be fixed on the displacement that the back up pad on back, base plate, the country rock crag also produces equivalent together with brake cable pipe and web joint, because an end of displacement transfer line is fixed in the rock stratum that does not produce displacement, the other end is on the reel of displacement detecting appearance displacement converted mechanism; Displacement transfer line in the brake cable pipe and brake cable pipe produce and relatively move; Its amount of movement equals the displacement that back, base plate, country rock crag and rock stratum produce, and the reel that the displacement transfer line drives in the throw-over gear of displacement detecting appearance rotates, after the information acquisition processing unit processes in the displacement detecting appearance; Through visualization processing, can demonstrate back and country rock strata displacement Changing Pattern figure again.The utility model patent roadway surrounding rock displacement both can have been monitored the absolute displacement amount of rock stratum from the face monitoring method, but also displacement monitoring rate of change is realized underworkings top, base plate and the remote real-time automatic monitoring of country rock body strata displacement.When displacement or rate of displacement surpassed safety margin, system can implement report to the police automatically to underworkings from ground monitoring master station, avoids the security incident that causes because of roof collapse, impulsion pressure.
Above-described embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that the common engineering technical personnel in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
