[0029] An arc frame 5 is arranged on the upper side of the adjusting frame 2, and the lower side of the arc frame 5 is plugged into the upper side of the adjusting frame 2. A limiting groove is arranged on the upper side of the arc frame 5, and a cross bar 6 is plugged into the limiting groove. The connection screws are threadedly connected at the connection between the cross bar 6 and the limiting groove, and the connection screws are also threadedly connected at the connection between the lower side of the arc frame 5 and the upper side of the adjusting frame 2.

[0030] A rack 7 is embedded inside the base frame 1, inside the adjustment frame 2 and on the top of the crossbar 6, and an annular frame 8 is sleeved outside the base frame 1, outside the adjustment frame 2 and outside the crossbar 6. A first rectangular through hole is provided inside the annular frame 8, and a gear 9 meshing with the rack 7 is rotatably connected inside the first rectangular through hole. A circle of positioning holes is evenly opened on the surface of the gear 9, and positioning components are provided on both sides of the first rectangular through hole. A monitoring component is installed on the outside of the annular frame 8.

[0031] The monitoring component includes an assembly box 10, a connecting seat 11 is welded on one side of the assembly box 10, the upper and lower sides of the connecting seat 11 are connected to the outer side of the annular frame 8 by screws, an adjusting screw 12 is rotatably connected to the inner wall of one side of the assembly box 10 through a bearing, one end of the adjusting screw 12 is threadedly connected to a transmission block 13, one side of the transmission block 13 is connected to a monitoring sensor 14, and a first limit plate 15 is arranged in the middle part of the transmission block 13.

[0032] A circular through hole corresponding to the monitoring actuator is opened on one side of the assembly box 10, the monitoring sensor 14 passes through the circular through hole and extends out from the inside of the assembly box 10, a rotating wheel 16 is arranged in the middle part of the adjusting screw 12, and a second rectangular through hole corresponding to the position of the rotating wheel 16 is opened on the front side of the assembly box 10.

[0033] The fixing assembly includes a concave fixing block 17. Dovetail grooves are provided on both sides of the adjustment frame 2 and the base frame 1. Dovetail blocks corresponding to the dovetail grooves are provided on the inner walls on both sides of the concave fixing block 17. The dovetail blocks inside the concave fixing block 17 are plugged into the dovetail grooves.

[0034] A limiting rod 18 is inserted into one side of the concave fixing block 17 . An external thread is formed on one side of the limiting rod 18 . A connecting nut 19 is threadedly connected to the external thread.

[0035] The positioning assembly includes a fixing plate 20 installed on the inner side of the annular frame 8, a connecting rod 21 is inserted into the middle part of the fixing plate 20, a second limiting plate 22 is connected to one side of the connecting rod 21, a return spring 23 is sleeved on the outer side of the connecting rod 21, a positioning rod 24 corresponding to the positioning hole is connected to one side of the second limiting plate 22, and the positioning rod 24 is inserted into the positioning hole opened on the gear 9.

[0036] When it is necessary to perform real-time deformation monitoring operation on the rock mass surrounding rock tunnel, the operator first plugs the lower side of the arc frame 5 with the upper side of the adjusting frame 2, and reinforces the plug-in place with connecting screws, then plugs the cross bar 6 with the upper limit groove of the arc frame 5, and also reinforces the plug-in place with connecting screws, and then inserts the upper and lower sides of the I-shaped block 4 into the strip-shaped slots on the upper side of the base frame 1 and the lower side of the adjusting frame 2, and the protrusions on the upper and lower sides of the I-shaped block 4 will be inserted into the limit opening. At this time, the operator can adjust the insertion height of the I-shaped block 4 according to the internal height of the tunnel. The device is adjusted by inserting the concave fixing block 17 into the joint between the I-shaped block 4 and the strip slot, and the connecting bolt is used to penetrate the I-shaped block 4 and is threadedly connected with the inner wall of the strip slot, thereby ensuring the tightness of the connection between the I-shaped block 4 and the base frame 1 and the adjustment frame 2, ensuring the overall stability of the device, and preventing the connection from loosening. At the same time, the limit rod 18 is plugged into one side of the concave fixing block 17, and the limit rod 18 is fixed with the connecting nut 19, further increasing the tightness of the connection between the I-shaped block 4 and the base frame 1 and the adjustment frame 2. The device as a whole can be quickly disassembled and assembled, which is convenient for operators to carry. The monitoring component is retractable as a whole, and it is highly practical.

[0037] After the assembly is completed, the operator can use the moving wheel 3 to move the device to the specified position inside the tunnel, and then use the positioning anchor rod 25 to fix the position of the device. After the device is fixed, the operator can use the circular pull ring 26 to pull the connecting rod 21 to drive the second limiting plate 22 and the positioning rod 24 to move. At the same time, the second limiting plate 22 compresses the reset spring 23 and separates the positioning rod 24 from the positioning hole opened on the gear 9. At this time, the position of the annular frame 8 outside the base frame 1, the adjustment frame 2 and the cross bar 6 can be moved. During the adjustment process, the gear 9 located inside the first rectangular through hole will rotate with the movement of the annular frame 8 and cooperate with the rack 7. After the annular frame 8 reaches the expected position, the operator stops pulling the connecting rod 21, the reset spring 23 is reset, and the positioning rod 24 is driven to re-insert with the positioning hole to limit the gear 9. At this time, the position of the annular frame 8 is fixed and cannot be moved, so that the position adjustment of the monitoring sensor 14 for surrounding rock deformation and the annular frame 8 can be realized.

[0038] Subsequently, the operator can rotate the rotating wheel 16 extending from the second rectangular through hole, thereby driving the adjusting screw 12 to rotate, so that the monitoring sensor 14 can be driven to extend from the inside of the assembly box 10 through the transmission block 13. At the same time, the distance between the monitoring sensor 14 and the inner wall of the tunnel can be adjusted so that the outer end of the monitoring sensor 14 is aligned with the inner wall of the tunnel, and thus the deformation of the inner wall of the tunnel can be monitored at the first time. A limiting slide bar 27 parallel to the adjusting screw 12 is provided on the inner wall of one side of the assembly box 10, and the first limiting plate 15 is slidably connected to the limiting slide bar 27 to increase the stability of the transmission block 13 during the adjustment process. The assembly box 10 is connected to the annular frame 8 through the connecting seat 11, and the operator can remove the assembly box 10 and perform maintenance operations on the monitoring sensor 14.

[0039] Finally, this technical solution can realize synchronous automatic surrounding rock deformation monitoring at multiple key positions inside the rock tunnel. The monitoring position is adjustable, the monitoring process is convenient and efficient, the monitoring area is large, the monitoring process is safe and reliable, and the number of devices can be adjusted according to usage requirements, thereby ensuring the accuracy of monitoring the internal deformation of the surrounding rock tunnel.

[0040] A positioning anchor rod 25 is inserted into the inner side of the base frame 1 to limit the position of the device and increase the stability of the device during operation.

[0041] A circular pull ring 26 is connected to one side of the connecting rod 21 to facilitate operators to pull the connecting rod 21 .

[0042] A limiting slide bar 27 parallel to the adjusting screw rod 12 is disposed on the inner wall of one side of the assembly box 10 , and the first limiting piece 15 is slidably connected to the limiting slide bar 27 to increase the stability of the transmission block 13 during the adjustment process.

[0043] A connecting bolt is inserted into one side of the concave fixing block 17 , and the connecting bolt passes through the I-shaped block 4 and is threadedly connected to the inner wall of the strip groove to ensure the tightness of the connection between the I-shaped block 4 and the base frame 1 and the adjustment frame 2 .

[0044] One side of the annular frame 8 is connected with a gate-type protection frame 28 by screws. Since stones may splash easily during construction inside the tunnel, the gate-type protection frame 28 can protect the gears 9 and connecting rods 21 and other components exposed inside the device.

[0045] Guide grooves are provided on the front and rear sides of the adjustment frame 2, the base frame 1 and the cross bar 6. Fastening bolts 29 corresponding to the guide grooves are threadedly connected on both sides of the annular frame 8. A rough layer is provided inside the guide groove. The guide groove can increase the stability of the movement of the annular frame 8. The fastening bolts 29 cooperate with the rough layer to increase the stability of the annular frame 8 after being fixed.
