[0001] The utility model relates to the technical field of mine shaft equipment, in particular to an intelligent device for analyzing shaft wall safety applied to mine shafts. Background Art

[0002] A mine shaft refers to a passage dug vertically downward from the surface to connect the ground with underground mineral layers. It is an important vertical passage for transporting personnel, materials and ores in mining. It is usually a vertical shaft with a circular or rectangular cross-section, through which miners, equipment, ores, etc. can be transported underground, or ores can be extracted from underground to the ground.

[0003] Mine shafts are often equipped with structures such as wooden supports and steel supports to temporarily support the shaft wall during excavation. Concrete linings, anchor spraying supports and other structures can also be set up to maintain the stability of the shaft for a long time. In other words, mine shafts are key facilities for mine production. Their safety is directly related to the life safety of miners and the smooth progress of mine production. The safety performance and stability of their shaft walls are of vital importance. Before setting up these supporting structures, as well as during the actual working process, it is often necessary to monitor the displacement, stress, strain, etc. of the shaft wall to ensure safety and reliability in the mine shaft. Therefore, it is necessary to design an intelligent detection and analysis device to conduct comprehensive and strict requirements and analysis on the monitoring of the shaft wall. Utility Model Content

[0004] The purpose of the utility model is to provide an intelligent device for safety analysis of shaft walls of mine shafts, which has the characteristics of multi-directional detection, analysis and fixation of shaft walls of mine shafts.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] The present application provides an intelligent device for shaft wall safety analysis applied to mine shafts. The intelligent safety analysis device includes a frame assembly, a connection assembly and a detection assembly. The frame assembly is located between the mine shafts. The connection assembly is arranged around the frame assembly and connected to the inner wall of the mine shaft. The detection assembly includes a displacement detection unit, a crack detection unit, an environment detection unit and a vibration detection unit. The displacement detection unit and the environment detection unit are arranged on the frame assembly, and the crack detection unit and the vibration detection unit are arranged on the connection assembly.

[0007] Furthermore, the frame assembly includes two groups of cross beams and longitudinal beams, and the cross beams and longitudinal beams are respectively provided in two groups, and are connected in pairs to form a square frame. An analysis assembly is provided inside the frame assembly.

[0008] Furthermore, the connecting assembly includes a positioning seat and a telescopic drill. The telescopic drill can rotate, and a propulsion member is provided in the positioning seat to push the telescopic drill to move horizontally.

[0009] Furthermore, the connecting assembly also includes a reinforcing rod, which is arranged on the positioning seat and wrapped around the outside of the telescopic drill. The reinforcing rod is connected to the propulsion member to drive the reinforcing rod to move horizontally through the propulsion member.

[0010] Furthermore, a crack detection portion is provided on the side wall of the reinforcing rod, which surrounds the reinforcing rod and faces the inner wall of the mine shaft.

[0011] Furthermore, the vibration detection part is arranged on the inner wall of the reinforcing rod, and a plurality of vibration detection parts are arranged at even intervals.

[0014] The technical solution provided by the utility model may have the following beneficial effects:

[0015] The utility model provides an intelligent device for analyzing the safety of shaft walls applied to mine shafts. The connecting components are arranged around the frame components to facilitate positioning of the intelligent device for safety analysis between the shaft walls. The connecting components are arranged around the frame components to make the connection more secure. The arrangement of the detection components enables the device to perform various detections on the shaft walls. For example, the displacement detection unit is used to determine whether the device has deviated based on the initial setting center, so as to infer whether the shaft wall has tilted or shaken. The crack detection unit is arranged at the connecting component. Since the connecting component needs to connect the safety analysis device to the shaft wall, it is inevitable to need to connect the connecting component to the shaft wall. Holes need to be drilled for installation, and the location of the holes is the area most likely to produce the first crack due to vibration. Therefore, the crack detection unit can detect cracks more quickly at the connecting components, improving the convenience of detection and analysis; secondly, humidity will affect the strength and stability of the well wall material. High humidity may cause the rock to soften and reduce strength, thereby increasing the risk of well wall collapse. The setting of the environmental detection unit can detect the humidity and temperature of the well wall in a certain area in real time; the vibration detection unit can monitor the vibration of the well wall to detect vibrations caused by blasting operations, mechanical operations, etc., to determine whether they affect the stability of the well wall and ensure the safety of the well wall.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more such features, and are used to distinguish between the described features, without distinction of order or importance.

[0025] In the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] The following combination Figures 1 to 3, describing the embodiments of the utility model provided in this application provides an intelligent device for shaft wall safety analysis applied to mine shafts, the intelligent safety analysis device includes a frame assembly 10, a connection assembly 20 and a detection assembly 30, the frame assembly 10 is located between the mine shafts, the connection assembly 20 is arranged around the frame assembly 10 and is connected to the inner wall of the mine shaft, the detection assembly 30 includes a displacement detection part 31, a crack detection part 32, an environment detection part 33 and a vibration detection part 34, the displacement detection part 31 and the environment detection part 33 are arranged on the frame assembly 10, and the crack detection part 32 and the vibration detection part 34 are arranged on the connection assembly 20.

[0028] Among them, Figure 2 As shown, the frame assembly 10 includes two transverse beams 11 and longitudinal beams 12 . There are two groups of transverse beams 11 and longitudinal beams 12 , which are connected in pairs to form a square frame. An analysis assembly 13 is provided inside the frame assembly 10 .

[0029] It is understandable that, under the condition that the weight does not exceed the standard, the frame assembly 10 can be set to a plurality of cross beams 11 and longitudinal beams 12 staggered and distributed as a square frame to improve the bearing effect of the frame, and, as Figure 2 As shown, a reinforcing rib 14 structure may be provided at the connection position between the cross beam 11 and the longitudinal beam 12 to further improve the connection strength and ensure the positioning effect.

[0030] Of course, the frame assembly 10 is not a hollow frame structure. The square frame composed of the horizontal beam 11 and the longitudinal beam 12 should be provided with flat plate structures at both ends to shield the internal analysis components 13 and circuits.

[0031] Furthermore, if Figure 1 and Figure 3 As shown, the connection assembly 20 includes a positioning base 21 and a telescopic drill 22. The telescopic drill 22 is rotatable, and a propeller 23 is provided within the positioning base 21 to propel the telescopic drill 22 horizontally. The positioning base 21 may be provided with a long slot for the telescopic drill 22 to be inserted therein, thereby positioning the telescopic drill 22 and providing a certain degree of protection.

[0032] For the propulsion member 23, a motor group can be used to provide horizontal movement and spiral rotation to the telescopic drill 22, so that the telescopic drill 22 can be inserted into the inner wall of the vertical shaft to perform positioning of the safety analysis intelligent equipment; and the drilling method has less impact on the wall of the vertical shaft than other hammering installation and extrusion installation methods, reducing the degree of crack opening on the wall of the vertical shaft and ensuring stability.

[0033] Of course, it should be noted that the entire safety analysis intelligent device is not positioned solely by the telescopic drill 22 structure. It also requires additional supporting equipment or a lifting device installed at the top of the shaft for synchronous support to ensure the stable positioning of the entire safety analysis intelligent device during the analysis process.

[0034] Furthermore, if Figure 3 As shown, the connecting assembly 20 further includes a reinforcing rod 24 , which is disposed on the positioning seat 21 and wrapped around the outside of the telescopic drill 22 . The reinforcing rod 24 is connected to the propulsion member 23 to drive the reinforcing rod 24 to move horizontally through the propulsion member 23 .

[0035] As for the reinforcing rod 24, it can be set as a hollow tubular structure, and the head end can be set as a cone-shaped structure inclined toward the center of the telescopic drill 22, so as to facilitate the penetration of a part of the structure of the reinforcing rod 24 into the hole drilled by the telescopic drill 22, so as to perform positioning together with the telescopic drill 22 and the reinforcing rod 24, thereby further improving the positioning effect; of course, as for the propulsion member 23, since it can adopt a motor group structure, one of the motors can be provided to drive the reinforcing rod 24 to move, which is easy to operate, or multiple output heads of the same motor can be used for power transmission to save space.

[0036] That is to say, when in use, the safety analysis intelligent equipment can be first transported to a suitable position through the hanging structure of the mine shaft mouth or other bearing structure, and the telescopic drill 22 can be driven to feed and rotate by the propeller 23, so that the telescopic drill 22 can gradually enter the well wall. After the hole is drilled, the telescopic drill 22 retreats and moves into the hole synchronously with the reinforcing rod 24, so that the reinforcing rod 24 and the telescopic drill 22 enter the hole at the same time. At this time, part of the drill bit of the telescopic drill 22 protrudes from the end of the reinforcing rod 24, which not only improves the positioning effect, but also when the feeding distance is insufficient, the telescopic drill 22 can continue to rotate to increase the feeding rate. The mud, sand, gravel and other structures brought out by the telescopic drill 22 can be partially left between the reinforcing rod 24 and the telescopic drill 22 to fill the reinforcing rod 24, so that the reinforcing rod 24 has an expansion-like effect, further improving the positioning effect.

[0037] In order to facilitate the detection of cracks in the shaft wall, multiple connecting assemblies 20 can be provided and evenly arranged on the outer walls of the crossbeam 11 and the longitudinal beam 12, and a crack detection part 32 is provided on the side wall of the reinforcing rod 24. The crack detection part 32 surrounds the reinforcing rod 24 and faces the inner wall of the mine shaft; in order to ensure a wider detection range, the crack detection part 32 can be provided with a universal head structure to perform multi-angle rotation.

[0038] The crack detection unit 32 may adopt an ultrasonic crack detector or a laser scanning head and perform multi-angle detection on the well wall at a certain distance to determine whether the crack will affect the firmness and safety of the well wall, thereby ensuring the safety and reliability of the well wall.

[0039] Furthermore, a vibration detection unit 34 is arranged on the inner wall of the reinforcing rod 24, and a plurality of vibration detection units 34 are arranged at even intervals. That is to say, a partially hollow structure can be provided in the reinforcing rod 24, and a plurality of vibration detection units 34 can be arranged in the hollow area to perform vibration detection on the reinforcing rod 24 area in real time; since the reinforcing rod 24 and the telescopic drill 22 are directly inserted into the well wall, the detection effect is more accurate.

[0040] As for the vibration detection part 34, it can use a vibration sensor to detect the vibration of the vertical shaft wall in real time to ensure the safety of the shaft wall; in order to improve the detection effect, an additional acoustic wave detector can be set in the reinforcing rod 24 to detect the acoustic wave reflection in the shaft wall, to analyze the cavities, cracks, etc. inside the shaft wall, and further improve the analysis and detection effect.

[0041] In addition, the displacement detection unit 31 is set at the bottom wall edge of the horizontal beam 11 and the longitudinal beam 12, and faces the inner wall of the mine shaft. It can analyze the displacement of the shaft wall, including horizontal and vertical displacement, to help determine whether the shaft wall is deformed or moved, which is an important indicator for judging the stability of the shaft wall.

[0042] The displacement detection unit 31 may include a horizontal sensor, a vertical sensor and a laser rangefinder. By respectively setting a horizontal sensor and a vertical sensor on the crossbeam 11 and the longitudinal beam 12, it is possible to determine in real time whether the entire safety analysis intelligent device has deviated from the initial position, thereby determining whether the well wall connected to the analysis intelligent device has shifted. In addition, the laser rangefinder can detect in real time the distance between the displacement detection unit 31 and the well wall. If the magnitude of the distance change exceeds the safe range, it can be determined whether the safety analysis intelligent device has shifted or the well wall itself has shifted. The detection effect is good and the detection range is wide.

[0043] Further, if Figure 2 As shown, the environment detection unit 33 is disposed inside the frame assembly 10 , and the analysis assembly 13 is connected to the environment detection unit 33 , the vibration detection unit 34 , the displacement detection unit 31 and the crack detection unit 32 respectively.

[0044] The environment detection unit 33 may be provided with a temperature sensor and a humidity sensor, such as Figure 2As shown, a placement groove is provided inside the frame assembly 10, and a filter structure is provided on the surface of the placement groove to reduce the invasion of gravel or large impurities. An environmental detection unit 33 can be provided in the placement groove to perform environmental detection on the area surrounding the safety analysis intelligent equipment to reduce the corrosion and impact on the well wall itself and the safety analysis intelligent equipment caused by changes in temperature and humidity, so as to ensure the stability of the entire vertical shaft.

[0045] In addition, in order to improve the effect of detection and analysis, a gas detector can be additionally installed in the installation tank. Since harmful gases may appear when working underground, the gas detector can simply analyze the gas and obtain a preliminary judgment on whether the gas is harmful. The gas detector can also temporarily store some of the gas to facilitate further analysis and judgment of the gas.

[0046] Of course, for the analysis component 13, it can use a single-chip microcomputer program to control the entire device, and can process and transmit the information collected by the environment detection part 33, the vibration detection part 34, the displacement detection part 31 and the crack detection part 32 to play the function of mid-end processing and transmission; in order to further analyze the data, a data center should be set up outside the vertical shaft to further process, analyze and store the information collected by this equipment, so as to improve the analysis efficiency and effect.

[0047] Furthermore, in an optional embodiment, in order to facilitate the positioning of the safety analysis intelligent device and to facilitate the detection of positions at different depths, a vertical rolling wheel 15 can be provided on the outer edge of the frame assembly 10. The rolling wheel 15 can contact the well wall and is configured as a retractable structure to cope with vertical shafts of different diameters. During use, if detection and analysis at positions at different depths are required, the diving depth of the safety analysis intelligent device can be controlled by the hanging structure outside the vertical shaft. The setting of the rolling wheel 15 can not only play a positioning role, ensuring that the safety analysis intelligent device can remain as horizontal as possible during vertical movement; it can also contact the well wall through the rolling wheel 15, thereby improving the operating stability of the safety analysis intelligent device, reducing collisions with the well wall, and making the operation more reliable and stable.

[0048] Other structures and operations of the intelligent device for safety analysis of shaft walls of mine shafts according to the embodiment of the utility model are known to those skilled in the art and will not be described in detail here.
