[0002] When conducting underground mining operations, the ground often rises or sinks due to disturbances. In severe cases, it can cause instability of buildings and the ground above the ground, resulting in cracks, deflections, collapses or uneven subsidence. Monitoring of ground subsidence and deformation has become an important part of the construction of necessary engineering facilities. During the construction of mine management, it is necessary to monitor the ground deformation, and the electronic micrometer is a common component for monitoring ground deformation.

[0023] A method for using a ground deformation monitoring device for mine management construction comprises the following steps:

[0024] S1. Insert the ground plug into the ground for mine management construction to be monitored, install the second fixing frame and the first fixing frame on the pre-prepared piles by bolts, the length of the shaft rod can be selected according to actual needs, and the remaining devices are supported and installed by the second fixing frame, the first fixing frame and the shaft rod;

[0025] S2. When the ground for mine management construction to be monitored undergoes deformation such as settlement, convexity or cracking, the ground plug will move accordingly. When the ground plug moves downward, the ground plug pulls down the swing rod through the support rod, causing the swing rod to swing downward, and the swing rod drives the V-shaped rod to rotate clockwise. One of the ratchets and the lever will push the second ratchet, and the other ratchet and lever will drag on the periphery of the first ratchet, so that the first ratchet and the second ratchet can drive the shaft to rotate clockwise. Similarly, when the ground plug moves upward, the swing rod will be pushed up by the support rod, causing the swing rod to swing upward, and the swing rod drives the V-shaped rod to rotate counterclockwise. One of the ratchets and the lever will push the first ratchet, and the other ratchet and lever will drag on the periphery of the second ratchet, so that the first ratchet and the second ratchet can drive the shaft to rotate counterclockwise.

[0026] S3. Initially, the pen core is located at the center line of the recording tape. A vertical scale line can be set on the outer wall of the recording tape to facilitate observation of the marking direction and distance of the pen core. The middle of the recording tape is supported by the support seat to facilitate marking of the pen core on the recording tape. The setting of the limit slide plate and the return spring enables the end of the pen core to always fit the surface of the recording tape.

[0027] S4. The clockwise and counterclockwise rotation of the shaft can respectively drive the first bevel gear to rotate clockwise and counterclockwise, the first bevel gear drives the insert cylinder to rotate through the second bevel gear, the insert cylinder drives the cross shaft to rotate, the cross shaft drives the second winding roller to rotate, when the second winding roller rotates clockwise, the second winding roller can rewind the recording tape, on the contrary, the first winding roller can release the recording tape, so that the recording tape moves left relative to the pen core, and the pen core is used to draw a line on the recording tape, and when the second winding roller rotates counterclockwise, the second winding roller The recording tape can be released. On the contrary, the first winding roller can wind up the recording tape, so that the recording tape moves rightward relative to the pen core. The pen core is used to draw a line on the recording tape. The sinking or convexity of the ground plug can be obtained by observing the direction and distance of the line. It should be noted that the winding spring is always in a tightened state, so that when the second winding roller releases the recording tape, the first winding roller can wind up the recording tape under the action of the spring elastic force, and when the second winding roller winds up the recording tape, it can further tighten the winding spring;

[0028] S5. In order to prevent the pen core from always drawing lines back and forth on the same horizontal position of the recording tape, so that different line segments cover each other and it is not possible to clearly observe the ground deformation frequency and the degree of each deformation, during the rotation of the insert, one of the sleeves can be driven to rotate under the action of the first sprocket, the second sprocket and the chain, and the sleeve drives the transmission bevel gear fixed thereto to rotate. Under the action of the third bevel gear, the two transmission bevel gears rotate synchronously in opposite directions. The transmission bevel gear can drive the U-shaped block inside it to revolve, and the two U-shaped blocks revolve in opposite directions. When the wedge inside one of the U-shaped blocks When the block can push the fourth ratchet, the wedge block inside the other U-shaped block can be moved on the outer periphery of the third ratchet by continuously shrinking. On the contrary, when the wedge block inside one of the U-shaped blocks can be shrunk and moved on the outer periphery of the fourth ratchet, the wedge block inside the other U-shaped block can push the outer periphery of the third ratchet, so that no matter the second sprocket rotates forward or backward, the third ratchet and the connecting shaft always drive the connecting shaft to rotate in the same direction, so that the screw rod can rotate unidirectionally. Under the action of the thread groove, the supporting seat can move up along the outer wall of the screw rod. At this time, the cross shaft moves up inside the insert cylinder, and the vertical plate moves up inside the first fixing frame;

[0029] S6. As the recording tape is rolled up and the horizontal plate moves upward, each line drawn by the pen core is an oblique line. When the horizontal distance remains unchanged and the ground deforms multiple times, the continuous broken lines on the recording tape can clearly show the degree, frequency and direction of deformation.

[0030] The working principle and beneficial effects of the present invention are:

[0031] 1. In the present invention, a shaft is provided between the second fixed frame and the first fixed frame, and a synchronization mechanism is connected between the shaft and the ground plug. When the ground plug is displaced such as sinking or cracking, the shaft can be rotated accordingly through the synchronization mechanism. The clockwise and counterclockwise rotation of the shaft can respectively drive the first bevel gear to rotate clockwise and counterclockwise. Under the action of the second bevel gear, the insert cylinder, the cross shaft and other structures, the second winding roller and the first winding roller can respectively wind up and release the recording tape, so that the recording tape moves left or right relative to the pen core, so that the pen core can draw a line on the recording tape, and the sinking or convex degree of the ground plug can be obtained by observing the direction and distance of the line. It is simple and clear, and has strong practicality.

[0032] 2. In the present invention, in order to prevent the pen core from always drawing lines back and forth on the same horizontal position of the recording tape, so that different line segments cover each other and it is impossible to clearly observe the ground deformation frequency and the degree of each deformation, in the process of synchronous driving of the transmission component and the supporting mechanism, the presentation component can be driven and supported by the lifting component, so that the trajectory can be drawn on the presentation component by the recording component, that is, in the process of retracting and releasing the recording tape, the cross plate can be moved up accordingly, so that each line drawn by the pen core is an oblique line. Under the condition of unchanged lateral distance (to facilitate penetrating the deformation amplitude), when the ground is deformed multiple times, the continuous broken lines on the recording tape can clearly derive the deformation degree, frequency and direction. The structure is simple and easy to use, and it provides a simple and efficient monitoring means for monitoring ground deformation in mine management construction, and has high use value and application prospects.

[0075] In this embodiment, when the wedge block 7064 inside one of the U-shaped blocks 7063 is able to push the fourth ratchet 7073, the wedge block 7064 inside the other U-shaped block 7063 is able to be moved around the outer periphery of the third ratchet 7071 by continuously contracting. Conversely, when the wedge block 7064 inside one of the U-shaped blocks 7063 is able to be contracted and moved around the outer periphery of the fourth ratchet 7073, the wedge block 7064 inside the other U-shaped block 7063 is able to be moved around the outer periphery of the third ratchet 7071 by continuously contracting. 64 can push the outer periphery of the third ratchet 7071, so that no matter the second sprocket 902 rotates forward or backward, the third ratchet 7071 and the connecting shaft 7072 always drive the connecting shaft 7072 to rotate in the same direction, so that the screw rod 704 can rotate in one direction. Under the action of the threaded groove 506, the supporting seat 503 can move up along the outer wall of the screw rod 704. At this time, the cross shaft 601 moves up inside the insert tube 802, and the vertical plate 602 moves up inside the first fixed frame 10.

[0076] In this embodiment, as the recording tape 504 is rolled up and the horizontal plate 603 moves upward, each line drawn by the pen core 401 is an oblique line. When the horizontal distance remains unchanged and the ground deforms multiple times, the continuous broken lines on the recording tape 504 can clearly show the degree, frequency and direction of deformation.

[0077] Working principle and usage process: First, insert the ground plug 1 into the ground for mine management construction to be monitored, install the second fixing frame 11 and the first fixing frame 10 on the pre-prepared piles (not shown in the figure) through bolts, and the length of the shaft rod 2 can be selected according to actual needs. The remaining devices are supported and installed by the second fixing frame 11, the first fixing frame 10 and the shaft rod 2.

[0078] In actual monitoring work, when the ground for mine management construction to be monitored sinks, bulges or cracks, the ground plug 1 will move accordingly. When the ground plug 1 moves down, the ground plug 1 pulls down the swing rod 302 through the support rod 301, so that the swing rod 302 swings down, and the swing rod 302 drives the V-shaped rod 303 to rotate clockwise, and one of the ratchet teeth 304 and the lever 305 will push the second ratchet 308, and the other ratchet tooth 304 and the lever 305 will drag the outer periphery of the first ratchet 307, so that the first ratchet The wheel 307 and the second ratchet 308 can drive the shaft 2 to rotate clockwise. Similarly, when the ground plug 1 moves up, the support rod 301 will push the rocker bar 302 upward, causing the rocker bar 302 to swing up, and the rocker bar 302 drives the V-shaped rod 303 to rotate counterclockwise. One of the ratchet teeth 304 and the shift rod 305 will push the first ratchet 307, and the other ratchet tooth 304 and the shift rod 305 will drag the outer periphery of the second ratchet 308, so that the first ratchet 307 and the second ratchet 308 can drive the shaft 2 to rotate counterclockwise.

[0079] Initially, the pen core 401 is located at the center line of the recording tape 504. Vertical scale lines can be set on the outer wall of the recording tape 504 to facilitate observation of the marking direction and distance of the pen core 401. The middle of the recording tape 504 is supported by the supporting seat 503 to facilitate the pen core 401 to mark on the recording tape 504. The setting of the limiting slide 404 and the return spring 406 enables the end of the pen core 401 to always fit the surface of the recording tape 504.

[0080] The clockwise and counterclockwise rotation of the shaft 2 can respectively drive the first bevel gear 801 to rotate clockwise and counterclockwise, the first bevel gear 801 drives the insert cylinder 802 to rotate through the second bevel gear 803, the insert cylinder 802 drives the cross shaft 601 to rotate, the cross shaft 601 drives the second winding roller 502 to rotate, when the second winding roller 502 rotates clockwise, the second winding roller 502 can rewind the recording tape 504, on the contrary, the first winding roller 501 can release the recording tape 504, so that the recording tape 504 moves left relative to the pen core 401, and the pen core 401 is used to draw a line on the recording tape 504, and when the second winding roller 502 rotates counterclockwise, the second winding roller 502 can rewind the recording tape 504, on the contrary, the first winding roller 501 can release the recording tape 504, so that the recording tape 504 moves left relative to the pen core 401, and the recording tape 504 is drawn by the pen core 401, and when the second winding roller 502 rotates counterclockwise, the second winding roller 502 can release the recording tape 504. On the contrary, the first winding roller 501 can wind up the recording tape 504, so that the recording tape 504 moves to the right relative to the pen core 401. The pen core 401 is used to draw a line on the recording tape 504. The degree of settlement or convexity of the ground plug 1 is obtained by observing the direction and distance of the line. It should be noted that the coil spring 507 is always in a tightened state, so that when the second winding roller 502 releases the recording tape 504, the first winding roller 501 can wind up the recording tape 504 under the action of the elastic force of the coil spring 507, and when the second winding roller 502 winds up the recording tape 504, it can further tighten the coil spring 507.

[0081] In order to prevent the pen core 401 from always drawing back and forth on the same horizontal position of the recording tape 504, so that different line segments cover each other and it is impossible to clearly observe the ground deformation frequency and the degree of each deformation, during the rotation of the insert cylinder 802, one of the sleeves 705 can be driven to rotate under the action of the first sprocket 901, the second sprocket 902 and the chain 903, and the sleeve 705 drives the transmission bevel gear 7061 fixed thereto to rotate. Under the action of the third bevel gear 708, the two transmission bevel gears 7061 rotate synchronously in opposite directions, and the transmission bevel gear 7061 can drive the U-shaped block 7063 inside it to revolve, and the two U-shaped blocks 7063 revolve in opposite directions. When the wedge block 7064 inside one of the U-shaped blocks 7063 can revolve on the fourth ratchet 7073 When the second sprocket 902 is pushed, the wedge block 7064 inside the other U-shaped block 7063 can be pushed on the outer periphery of the third ratchet 7071 by continuously shrinking. On the contrary, when the wedge block 7064 inside one of the U-shaped blocks 7063 can be shrunk and moved on the outer periphery of the fourth ratchet 7073, the wedge block 7064 inside the other U-shaped block 7063 can push the outer periphery of the third ratchet 7071, so that no matter the second sprocket 902 rotates forward or backward, the third ratchet 7071 and the connecting shaft 7072 always drive the connecting shaft 7072 to rotate in the same direction, so that the screw rod 704 can rotate unidirectionally. Under the action of the thread groove 506, the supporting seat 503 can move up along the outer wall of the screw rod 704. At this time, the cross shaft 601 moves up inside the insert cylinder 802, and the vertical plate 602 moves up inside the first fixing frame 10.

[0082] As the recording tape 504 is rolled up and the horizontal plate 603 moves upward, each line drawn by the pen core 401 is an oblique line. When the horizontal distance remains unchanged and the ground deforms multiple times, the continuous broken lines on the recording tape 504 can clearly show the degree, frequency and direction of deformation.
