Technical Field

[0001] The utility model relates to the technical field of tunnel surrounding rock deformation monitoring devices, in particular to a multi-point delamination instrument and a coupling monitoring device using the multi-point delamination instrument. Background Art

[0002] The roof of a coal mine is a typical layered structure. When mining coal seams underground, the balance of the rock mass around the working face is destroyed. As the working face continues to advance, the roof will lose support and sink to varying degrees. The amount of sinking determines the safety of the roof. The displacement monitoring of the old roof and the direct roof is a necessary technical means to judge the safety of the roof. When encountering complex roofs such as thick coal mine roofs, fragile roofs, or soft rock mass, relying solely on two monitoring points cannot meet the needs of tunnel safety monitoring. A multi-point delamination instrument is required to carefully observe the safety of the roof. For the same reason, the deformation of the two sides of the tunnel also requires a multi-point delamination instrument to carefully observe the safety of the two sides of the tunnel. The existing multi-point delamination monitor has a complex structure and cannot measure the deformation of each side of the tunnel. This is the shortcoming of the existing technology. Summary of the invention

The multi-point delamination meter has a simple structure and can effectively monitor the displacement of the rock strata in the tunnel; the multi-point delamination meter is equipped with a millimeter-wave radar ranging sensor, and the respective deformation amounts on both sides of the tunnel can be obtained through the coupling of the multi-point delamination meter and the millimeter-wave radar ranging sensor.

[0004] The present scheme is realized through the following technical measures: a multi-point separation instrument, comprising a shell, in which a multi-point separation instrument sensor is arranged, the multi-point separation instrument sensor comprises a sensor shell, in which a wire wheel is arranged, the wire wheel is connected with a mainspring, the wire wheel can rotate synchronously with the rotation system of a potentiometer, and the potentiometer is connected with a circuit board; a steel wire rope I is arranged on the wire wheel, the steel wire rope I can be connected with an anchor claw steel wire rope, the anchor claw steel wire rope is connected with the anchor claw, and a plurality of anchor claws are arranged.

[0005] Preferably, when in use, a plurality of anchor claws are respectively arranged at different positions of the tunnel rock formation.

[0006] Preferably, the number of the reel, the mainspring, the potentiometer, the wire rope I, and the anchor wire rope corresponds to the number of the anchor claws.

[0007] Preferably, the wire wheel is connected to the rotation system of the potentiometer via an adapter sleeve.

[0008] Preferably, the circuit board is connected to the connector via a communication cable.

[0009] Preferably, the shell is fixedly connected with a guide tube, an anchor head is provided at the upper end of the guide tube, and the anchor claw wire rope passes through the guide tube, the anchor head and is connected with the anchor claw.

[0012] A coupling monitoring device comprises a multi-point delamination instrument, on which a millimeter wave radar ranging sensor is arranged.

[0013] Compared with the prior art, the utility model has the following advantages:

The steel wire rope I is connected to the anchor claw steel wire rope through a connecting block.

When the rock formation is displaced, the steel wire rope I drives the reel to rotate, and the reel is connected to the rotation system of the potentiometer through an adapter sleeve, so that the rotation system of the potentiometer rotates synchronously with the reel. The potentiometer converts the received signal into an electrical signal and transmits it to the circuit board to monitor the displacement of the rock formation.
