Description

Technical Field

[0001] The utility model relates to the technical field of mine subsidence monitoring, in particular to multifunctional mine subsidence monitoring equipment. Background Art

[0002] Mine subsidence refers to the phenomenon that the surface or underground structure sinks or falls during the mining process. This subsidence phenomenon is mainly caused by the collapse of the goaf, changes in surface water levels, surface extrusion and collapse of underground cavities. In order to ensure the safety and stability of mining projects, various instruments are usually used to monitor the mining area. The most important thing is to ensure the safety of people who step on the air underground, so it is particularly important to monitor the subsidence below the mine.

[0003] At present, most of the existing mine subsidence monitoring equipment uses laser measuring instruments to measure the height of the ground in the mine from the cave top, so as to determine the subsidence situation. However, it cannot support the mine while measuring, and cannot improve safety protection measures, resulting in a large number of casualties when accidents occur. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the existing technology, the utility model provides a multifunctional mine settlement monitoring equipment, which has the advantages of being able to provide stop support force in the mine while monitoring the settlement, further improving the support effect on the original support structure, and improving the safety of mine construction. It solves the problem that the current monitoring instruments are single and cannot play a role in supporting the mine while monitoring, resulting in a large number of casualties in the event of an accident.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional mine settlement monitoring device, including a support assembly and a monitoring assembly, the support assembly including a support tube, on which two regulating rings are movably hinged, the regulating rings are threadedly connected to the sides of the support rod, and the support rod is movably sleeved in the support tube, both ends of the support tube are provided with holes, and support rods are sleeved in the holes, the shape of the holes is consistent with the shape of the sides of the support rod, limiting the support rod to move up and down in the support tube but not to rotate, so that the support rod can be telescopically moved by rotating the regulating ring clockwise or counterclockwise, which can meet the function of supporting mines of different heights.

[0008] The monitoring component includes a monitor movably connected to a support rod, a connecting ring is movably hinged at one end of the monitor, the connecting ring is threadedly connected to the support rod, a connecting tube is movably sleeved at the other end of the monitor, a telescopic rod is movably sleeved in the connecting tube, a contact rod is fixed at one end of the telescopic rod, and a signal transmitter is fixed in the connecting tube, and a signal receiver is fixed at one end of the telescopic rod, and the signal transmitter corresponds to the signal receiver. The two support rods are both installed with a monitoring component. When the support component is in the supporting process, the contact rod is made to fit the corresponding top surface and ground of the mine cave. At the same time, the signal transmitter can set the interval time for each time it sends command information, and control the operation of the signal transmitter according to the interval time, send command information to the signal receiver, and receive the command information through the signal receiver. The total time taken from sending the command to receiving the command is used to judge the height of the settlement, so that when settlement occurs, the telescopic rod is retracted into the connecting tube under pressure, so that the signal receiver is close to the signal transmitter, thereby shortening the distance of signal transmission, and judging the height of the settlement by the time from signal transmission to reception.

[0009] As a further improvement of the above solution, one end of the monitor is movably hinged with an adjustment ring, and the adjustment ring is threadedly connected to the side of the connecting tube.

[0010] Through the above technical solution, when the adjusting ring is rotated clockwise, the connecting tube moves up and down under the force of the threaded connection between the adjusting ring and the side of the connecting tube, so that the height of the contact rod can be adjusted so that the top of the contact rod can fit the top surface or the ground of the mine.

[0011] As a further improvement of the above solution, a limiting block is fixed in the monitor, and a limiting sliding groove is provided on the side of the connecting tube, and the limiting block is slidably connected in the limiting sliding groove.

[0012] Through the above technical solution, when the connecting tube telescopes and moves in the monitor, the limit block slides in the limit slide groove to prevent the connecting tube from detaching from the monitor. At the same time, when the adjusting ring rotates, it can also prevent the connecting tube from rotating at the same time, so that the connecting tube can telescope and move smoothly in the monitor.

[0013] As a further improvement of the above solution, a tension spring is fixed in the connecting tube, and one end of the tension spring is fixed to one end of the telescopic rod.

[0014] Through the above technical solution, the tension spring has the function of expanding and pushing the telescopic rod, so that the telescopic rod can fit into the top surface or the ground of the mine. When subsidence occurs, the telescopic rod is subjected to pressure, the tension spring is tightened, and the telescopic rod moves deeper into the monitor. When not under pressure, the tension spring pushes the telescopic rod to move outward from the inside of the monitor.

[0015] As a further improvement of the above scheme, a conical block is fixed on the side of the monitor, a mounting tube is fixed on the conical block, a push rod is movably sleeved in the mounting tube, and a positioning ring is movably hinged at one end of the mounting tube, and the positioning ring is threadedly connected to the side of the push rod.

[0016] Through the above technical solution, four conical blocks are fixed in a ring on the side of the monitor. The inclined surface of the conical block is 45°, and a mounting tube is fixed on the inclined surface. The side of the top rod is octagonal and coincides with the inside of the mounting tube, and the side is connected to the inner thread of the positioning ring. By rotating the positioning ring clockwise or counterclockwise, the top rod can be telescoped and moved to set the support height.

[0017] As a further improvement of the above solution, an extension rod is inserted into one end of the push rod, and a fixing screw is fixed to one end of the extension rod.

[0018] Through the above technical solution, a hole is opened at the tail end of the extension rod, and the depth of the hole is half of the length of the extension rod, so that after the top end of the extension rod is subjected to force, it moves from the front end of the top rod to the tail end. When the front end of the top rod fits into the depth of the hole, it achieves a supporting function to prevent the mine from collapsing. At the same time, the device is fixed by being threadedly connected to the top surface or ground of the mine through the fixing screw.

[0019] As a further improvement of the above solution, a mounting rod is fixed to the side of the mounting tube, a stabilizing rod is fixed to one end of the mounting rod, and a socket block is fixed to one end of the extension rod, and the socket block is movably socketed on the side of the stabilizing rod.

[0020] Through the above technical solution, when the extension rod is forced to move downward, the sleeve block slides on the side of the stabilizing rod, thereby improving the stability of the extension rod's telescopic movement.

[0021] As a further improvement of the above solution, a spring rod is movably sleeved on the side of the stabilizing rod, and the spring rod is movably connected between the sleeve block and the mounting rod.

[0022] Through the above technical solution, the spring rod has the function of expanding and pushing the sleeve block to move upward, so that the extension rod fits on the top surface or the ground of the mine.

[0023] As a further improvement of the above solution, one end of the stabilizing rod is threadedly connected to a limiting ring, and the limiting ring is fitted on the sleeve block.

[0024] Through the above technical solution, the limiting ring is rotated clockwise or counterclockwise so that the limiting ring moves on the side of the stabilizing rod, thereby achieving the function of limiting the length of the extension rod support.

[0025] Compared with the prior art, the utility model provides a multifunctional mine subsidence monitoring device, which has the following beneficial effects:

[0026] 1. The multifunctional mine settlement monitoring equipment, through the cooperation of the support tube and the support rod, makes the monitoring components installed at the top and bottom fit on the corresponding positions of the mine cave top surface and the ground, and adjusts the length of the top rod so that during the settlement process, the extension rod moves downward and is supported by the top rod. At the same time, during the support process, the top end of the contact rod fits on the mine cave top surface or the ground. During settlement, the contact rod is subjected to pressure, so that the telescopic rod moves deep into the connecting tube, and the internal signal transmitter sends command information to the signal receiver in real time. The settlement height is judged by the duration of the command received by the signal receiver. The shorter the duration, the closer the signal receiver is to the signal transmitter, and the greater the settlement height, and the longer the duration, the farther the distance between the signal receiver and the signal transmitter, and the smaller the settlement height. Therefore, it can effectively and accurately monitor the settlement height and time while playing a role in supporting the mine cave.

[0027] 2. This multifunctional mine settlement monitoring equipment controls the outward movement length of the support rod by rotating the regulating rings at both ends of the support tube and the force of the threaded connection between the regulating ring and the side of the support rod, so that the device can be used for monitoring and support work in mines at different heights, further improving the practicality and flexibility of the device.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Embodiment 1

[0038] See also Figure 1-5 As shown, the multifunctional mine settlement monitoring equipment proposed in this embodiment includes a support component 1 and a monitoring component 2. The support component 1 includes a support tube 101, and two regulating rings 102 are movably hinged on the support tube 101. The regulating ring 102 is threadedly connected to the side of the support rod 103, and the support rod 103 is movably sleeved in the support tube 101. Holes are opened at both ends of the support tube 101, and support rods 103 are sleeved in the holes. The shape of the hole is consistent with the shape of the side of the support rod 103, which limits the support rod 103 to move up and down in the support tube 101 but not to rotate. Therefore, by rotating the regulating ring 102 clockwise or counterclockwise, the support rod 103 can be telescopically moved, which can meet the function of supporting mines of different heights.

[0039] The monitoring assembly 2 includes a monitor 201 movably connected to the support rod 103, one end of the monitor 201 is movably hinged with a connecting ring 202, the connecting ring 202 is threadedly connected to the support rod 103, the other end of the monitor 201 is movably sleeved with a connecting tube 204, a telescopic rod 206 is movably sleeved in the connecting tube 204, one end of the telescopic rod 206 is fixed with a contact rod 211, and a signal transmitter 205 is fixed in the connecting tube 204, and a signal receiver 207 is fixed at one end of the telescopic rod 206, and the signal transmitter 205 corresponds to the signal receiver 207. The monitoring assembly 2 is installed on both of the support rods 103. When the support assembly 1 is on the support During the support process, the contact rod 211 is made to fit the corresponding top surface and ground of the mine cave. At the same time, the signal transmitter 205 can set the interval time for each time it sends command information, and control the operation of the signal transmitter 205 according to the interval time, send command information to the signal receiver 207, and receive the command information through the signal receiver 207. The total time taken from sending the command to receiving the command is used to judge the height of the settlement. Therefore, when settlement occurs, the telescopic rod 206 is retracted into the connecting tube 204 under pressure, so that the signal receiver 207 is close to the signal transmitter 205, thereby shortening the distance of signal transmission, and judging the height of the settlement by the time from signal transmission to reception.

[0040] The working principle of the multifunctional mine settlement monitoring device proposed in this embodiment is: when in use, the device is moved as a whole into the mine cave, and in a vertical placement state, the top and bottom monitoring components 2 are aligned with the monitoring positions of the required settlement on the top and ground of the mine cave. At this time, the top and bottom regulating rings 102 are rotated one by one to extend the support rod 103 until the fixing screws 217 of the monitoring components 2 on both sides are attached to the corresponding surfaces of the mine cave, and the fixing screws 217 are drilled into the top and bottom of the mine cave to make it reach a fixed state. At this time, the positioning ring 214 is rotated clockwise or counterclockwise to adjust the length of the top rod 215 at a depth, so that after the mine cave settles to a certain height, the extension rod 216 moves downward until the top rod 215 is close to the deepest part of the aperture opened by the extension rod 216 for support, and during installation, By rotating the adjustment ring 203, the connecting tube 204 drives the contact rod 211 to move upward at the same time, so that the top and bottom contact rods 211 are attached to the top surface or the ground of the mine, and the internal signal transmitter 205 and signal receiver 207 are controlled to operate. At the same time, the signal receiver 207 is connected to the external alarm, and the signal transmitter 205 sends out a light signal in real time according to the set interval time. When the light signal is sent, the timing is automatically started (the timing data is accurate to milliseconds) until the signal receiver 207 receives the total time of the light signal, so as to determine the distance between the signal receiver 207 and the signal transmitter 205, thereby monitoring the settlement height of the mine in real time, and by setting the timeline of the signal receiver 207 receiving, when the receiving time is less than the set timeline, the connected external alarm is automatically controlled to sound an alarm.

[0041] Furthermore, an adjustment ring 203 is movably hinged at one end of the monitor 201 , and the adjustment ring 203 is threadedly connected to the side of the connecting tube 204 .

[0042] More specifically, when the adjusting ring 203 is rotated clockwise, the connecting tube 204 moves up and down under the force of the threaded connection between the adjusting ring 203 and the side of the connecting tube 204, thereby adjusting the height of the contact rod 211 so that the top of the contact rod 211 can fit the top surface or the ground of the mine.

[0043] Furthermore, a limiting block 209 is fixed inside the monitor 201 , and a limiting sliding groove 210 is provided on the side of the connecting tube 204 , and the limiting block 209 is slidably connected in the limiting sliding groove 210 .

[0044] More specifically, when the connecting tube 204 telescopes and moves in the monitor 201, the limit block 209 slides in the limit slide groove 210, preventing the connecting tube 204 from being separated from the monitor 201, and preventing the adjusting ring 203 from rotating and driving the connecting tube 204 to rotate at the same time, so that the connecting tube 204 can move telescopically and smoothly in the monitor 201.

When subsidence occurs, the telescopic rod 206 is subjected to pressure, the tension spring 208 is tightened, and the telescopic rod 206 moves deeper into the monitor 201. When not subjected to pressure, the tension spring 208 has the effect of pushing the telescopic rod 206 to move from the inside of the monitor 201 to the outside.

[0047] Furthermore, a conical block 212 is fixed to the side of the monitor 201, a mounting tube 213 is fixed on the conical block 212, a top rod 215 is movably sleeved in the mounting tube 213, and a positioning ring 214 is movably hinged at one end of the mounting tube 213, and the positioning ring 214 is threadedly connected to the side of the top rod 215.

[0049] Furthermore, an extension rod 216 is inserted into one end of the top rod 215 , and a fixing screw 217 is fixed to one end of the extension rod 216 .

[0050] More specifically, a hole is provided at the tail end of the extension rod 216, and the depth of the hole is half the length of the extension rod 216, so that after the top end of the extension rod 216 is subjected to force, it moves from the front end of the top rod 215 to the tail end. When the front end of the top rod 215 fits into the depth of the hole, it achieves a supporting function to prevent the mine from collapsing. At the same time, it is threadedly connected to the top surface or ground of the mine through the fixing screw 217 to achieve the function of fixing the device.

[0051] Furthermore, a mounting rod 218 is fixed to the side of the mounting tube 213 , a stabilizing rod 219 is fixed to one end of the mounting rod 218 , and a sleeve block 220 is fixed to one end of the extension rod 216 , and the sleeve block 220 is movably sleeved on the side of the stabilizing rod 219 .

[0052] More specifically, when the extension rod 216 is forced to move downward, the sleeve block 220 slides on the side of the stabilizing rod 219, thereby improving the stability of the extension rod 216 in telescopic movement.

[0053] Furthermore, a spring rod 222 is movably sleeved on the side of the stabilizing rod 219 , and the spring rod 222 is movably connected between the sleeve block 220 and the mounting rod 218 .

[0054] More specifically, the spring rod 222 has the function of expanding and pushing the sleeve block 220 to move upward, so that the extension rod 216 is attached to the top surface or the ground of the mine.

[0055] Furthermore, one end of the stabilizing rod 219 is threadedly connected to a limiting ring 221 , and the limiting ring 221 is fitted on the sleeve block 220 .

[0056] More specifically, by rotating the limiting ring 221 clockwise or counterclockwise, the limiting ring 221 moves on the side of the stabilizing rod 219 , thereby limiting the length of the extension rod 216 .
