Description

Technical Field

[0001] The invention relates to the technical field of mining, and in particular to a supporting device used for filling and mining in underground mines. Background Art

[0002] In the process of oilfield development, according to the needs of oilfield adjustment, transformation, improvement and potential tapping, and in accordance with the requirements of process design, a set of ground and underground equipment and tools are used to take various underground technical measures for oil and water wells to increase injection and production volume, improve oil layer seepage conditions and oil and water well technical conditions, and increase oil production speed and final recovery rate. This series of underground construction technology is collectively referred to as underground operations. Mine tunnels are a general term for various underground spaces that are excavated in different rocks along different directions, at different inclinations, and in different sections and lengths, serving different ranges and for different purposes. Mine tunnels are named and classified according to their spatial size, inclination direction, location, service range and purpose. Mine tunnels need to be supported by support devices.

[0003] A support device for underground filling and mining is disclosed in the patent document with application number: CN202110158207.1.

[0004] However, it still has the following shortcomings in practical application:

[0005] First, the supporting effect is not good, because it simply supports the upper end of the well wall, but the side well wall also needs to be supported, and the device in the above-mentioned comparative document is prone to displacement after long-term use (the reasons include but are not limited to collisions with operating vehicles, changes in pressure on the well wall, etc.).

[0006] Second, the safety is poor because after it is completed, the workers in the mine cannot intuitively and quickly understand whether its support for the mine wall is loose; in addition, the workers cannot intuitively and quickly understand whether the pressure of the mine wall on them is abnormal, which results in the workers not being able to receive early warning before the mine collapses, resulting in the workers not being able to repair the problem section of the wall in time or escape. Summary of the invention

[0007] The purpose of the present invention is to solve the shortcomings of the prior art and the problems raised in the above background technology.

[0008] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a supporting device used for filling and excavation in underground mines, comprising a supporting assembly for supporting a shaft wall and a detection assembly arranged on the supporting assembly;

[0009] The support assembly includes a jacking unit and a side thrust unit;

[0010] The detection component includes a pressure detection unit and an alarm unit.

[0011] Furthermore, the jacking unit includes a cross arm and a telescopic rod. The number of cross arms is at least two, and the cross arms are arranged in parallel. Adjacent cross arms are movably connected by a first connecting rod. Telescopic rods are movably arranged at both ends of the cross arm. The cross section of the free rod of the telescopic rod is a regular polygon. Adjacent fixed rods of two telescopic rods at the same end in the mine traveling direction are movably connected by a second connecting rod. A set of transverse screw grooves are symmetrically formed along the long side direction of the second movable rod;

[0012] The side push unit includes bolts rotatably connected symmetrically in the transverse screw grooves and gaskets arranged on the bolts.

[0013] Furthermore, the telescopic rod is hydraulically driven. Bottom plates are fixedly arranged at the bottoms of the telescopic rods. A set of reserved holes are symmetrically formed on the bottom plates. Ground nails matching the reserved holes are inserted through the reserved holes.

[0014] Furthermore, the bolt head of the bolt is rotatably connected in the rotation groove on the gasket. An installation groove coaxial with the bolt is formed through the bolt body of the bolt. A pressure-induced color-changing rod is arranged in the installation groove. The part of the pressure-induced color-changing rod in the rotation groove is extruded by the bolt head.

[0015] Furthermore, the pressure detection unit includes a pressure sensor and a flexible block. A set of flexible blocks are symmetrically distributed on the side wall surfaces of the upper ends of the cross arm and the first connecting rod. Pressure sensors are buried in the flexible blocks;

[0016] The alarm unit includes a warning light and a speaker arranged on the fixed rod.

[0017] Furthermore, any two of the pressure sensors are in a parallel relationship. Indicator lights corresponding to the pressure sensors one by one are arranged on the side wall surfaces of the lower ends of the cross arm and the first connecting rod. The pressure sensors, warning lights, speakers, and indicator lights are all powered by an external power supply and controlled by a control center outside the mine.

[0018] Furthermore, a lighting lamp, an air quality monitor, and a life detector are arranged on the fixed rod.

[0019] Furthermore, a PLC controller for controlling the lighting lamp, the air quality monitor, and the life detector is also arranged on the fixed rod. The PLC controller, the lighting lamp, the air quality monitor, and the life detector are all powered by an emergency storage battery arranged on the fixed rod.

[0020] Furthermore, the PLC controller is controlled by a control center arranged outside the mine, and the PLC controller has an independent identity number in the control system of the control center. The PLC controller is built-in with a wireless communication module and a positioning module.

[0021] Furthermore, a wireless intercom is integrated on the PLC controller, and the keys, microphone and speaker of the wireless intercom are all arranged on the outer surface of the shell of the PLC controller.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0023] 1. Through the design of arranging the jacking unit and the side pushing unit in the support assembly, the present invention supports the mine shaft walls at the top and side ends of the mine through the jacking unit and the side pushing unit respectively, achieving the effect of effectively improving the support and protection of the mine shaft wall.

[0024] 2. Through the design that a bottom plate is fixed at the bottom of the fixed rod in the jacking unit, and reserved holes are opened on the bottom plate, and ground nails are inserted through the reserved holes, the position of the telescopic rod can be firmly fixed by the ground nails, thereby preventing the telescopic rod from shifting.

[0025] 3. Through the design that a pressure-induced color-changing rod is arranged on the bolt in the side pushing unit, and the pressure-induced color-changing rod is squeezed by the gasket and the bolt, it is convenient for workers to judge whether the gasket is tightly pressed against the mine side wall by checking the color of the pressure-induced color-changing rod.

[0026] 4. Through the design that pressure detection units are arranged on both the cross arm and the first connecting rod, and the pressure sensors in the pressure detection units are all controlled by the control center outside the mine. In addition, indicator lights corresponding to the pressure sensors one by one are arranged on the side wall surfaces at the lower ends of the cross arm and the first connecting rod, the control center can thus monitor the pressure change of the mine shaft wall on the support assembly in real time through the pressure sensors and give information feedback to the workers in the mine through the indicator lights.

[0027] 5. By adding an alarm unit, which includes a warning light and a speaker arranged on the fixed rod, the present invention can cooperate with the pressure detection unit to accurately feedback its detection results.

[0028] 6. In the present invention, a lighting lamp, an air quality monitor, a life detector, an emergency battery, and a PLC controller are provided on a fixed rod. The PLC controller is controlled by a control center arranged outside the mine, and the PLC controller has an independent identity number in the control system of the control center. With the design that the PLC controller is built-in with a wireless communication module and a positioning module, the air quality monitor can accurately monitor whether the air quality in each section of the mine meets the standard. At the same time, when a collapse occurs inside the mine, the PLC controller and the life detector can help rescue workers quickly locate the trapped personnel.

[0029] 7. With the design that a wireless intercom is integrated on the PLC controller in the present invention, when a collapse occurs in the mine, the trapped personnel can contact the control center outside the mine through the wireless intercom, thus helping the rescue workers quickly carry out the rescue.

[0048] In order to more clearly understand the above - mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0049] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0050] A support device for underground filling and mining in a mine in this embodiment, with reference to Figure 1-6 : It includes a support component 1000 for supporting the shaft wall and a detection component 2000 arranged on the support component 1000. (I)

[0052] Because the roadway in the mine is not only subjected to huge pressure from the top wall of the roadway, but also the side wall of the roadway will be subjected to horizontal pressure. In addition, the vibration generated during the construction of adjacent roadways will also cause fluctuations in these pressures. Therefore, in order to ensure the stability of the roadway in the mine, a jacking unit 1100 for supporting the top wall of the mine and a side - pushing unit 1200 for supporting the side wall of the mine need to be respectively arranged in the support component 1000.

[0053] (I - I)

[0054] The jacking unit 1100 includes a cross arm 1101 and a telescopic rod 1102. The number of cross arms 1101 is at least two (in this embodiment, for the convenience of description and expression, two cross arms 1101 are taken as an example). The cross arms 1101 are arranged in parallel, and adjacent cross arms 1101 are movably connected by a first connecting rod 1103. Telescopic rods 1102 are movably arranged at both ends of the cross arm 1101. The cross section of the free rod 1104 of the telescopic rod 1102 is a regular polygon (this can effectively prevent the free rod 1104 from spinning during the process of sliding on the fixed rod 1105, thereby improving the stability and reliability of the jacking unit 1100). The fixed rods 1105 of two adjacent telescopic rods 1102 at the same end in the mine traveling direction are movably connected by a second connecting rod 1106. A set of transverse screw grooves 1107 are symmetrically arranged along the long side direction of the second movable rod.

[0055] The telescopic rod 1102 is hydraulically driven because hydraulics has the advantages of convenient operation and control (it can achieve stepless speed regulation over a wide range), automatic overload protection, long service life (because it generally uses mineral oil as the working medium and the relative moving surfaces can lubricate themselves), easy to achieve linear motion, easy to automate the machine (when electro-hydraulic combined control is adopted, not only can a higher degree of automatic control process be achieved, but also remote control can be realized), small motion inertia, and fast response speed.

[0056] Bottom plates 1108 are fixedly arranged at the bottoms of the telescopic rods 1102. Two reserved holes 1109 are symmetrically arranged on each bottom plate 1108. Ground nails 1110 that match the reserved holes 1109 are inserted through the reserved holes 1109. In this way, after the position of the telescopic rod 1102 is fixed, workers can drive the ground nails 1110 through the reserved holes 1109 into the ground, thereby firmly restricting the position of the telescopic rod 1102 and preventing the supporting effect of the supporting component 1000 on the mine shaft wall from decreasing due to the displacement of the telescopic rod 1102.

[0057] (One - Two)

[0058] The side - pushing unit 1200 includes bolts 1201 rotatably connected symmetrically in the transverse screw grooves 1107 and gaskets 1202 arranged on the bolts 1201. In this way, after the worker finishes building the jacking unit 1100, the end gasket 1202 can be firmly pressed against the side wall of the mine by rotating the bolt 1201.

[0059] It should be noted that in the actual application process, the screw and the gasket 1202 can also be applied to the first connecting rod 1103, thereby improving the precise support of the jacking unit 1100 for the mine top wall.

[0060] The bolt head of the bolt 1201 is rotatably connected to the rotating groove 1203 on the gasket 1202. An installation groove 1204 coaxial with it penetrates through the bolt body of the bolt 1201. A pressure-sensitive color-changing rod 1205 is provided in the installation groove 1204. The part of the pressure-sensitive color-changing rod 1205 in the rotating groove 1203 is squeezed by the bolt head of the bolt 1201. In this way, when the bolt 1201 gradually presses the gasket 1202 against the side wall of the mine, the part of the pressure-sensitive color-changing rod 1205 in the rotating groove 1203 will be squeezed by the bolt head of the bolt 1201 and the inner wall of the rotating groove 1203, so that the pressure-sensitive color-changing rod 1205 gradually changes color due to the gradually increasing pressure on it.

[0061] In this embodiment, the color-changing rule of the pressure-sensitive color-changing rod 1205 is that as the pressure increases, the color gradually changes from light red to dark red. In this way, when workers patrol in the mine, they can use the color card carried with them to distinguish the color of the pressure-sensitive color-changing rod 1205, and combine the tightening degree values corresponding to each color marked on the color card (the tightening degree value corresponds to the magnitude of the pressure on the pressure-sensitive color-changing rod 1205 (i.e., the tightening degree between the gasket 1202 and the side wall of the mine)) to quickly understand the tightening degree of the side pushing unit 1200 against the side wall of the mine. (Two)

[0063] Because the pressure on the inner wall of the mine is not constant. Once the pressure balance on the inner wall of the mine is broken, there will be a risk of mine collapse, thus endangering the safety of the mine workers and causing inestimable property losses. Therefore, in order to ensure the safe operation of the mine, a pressure detection unit 2100 for detecting the pressure on the inner wall of the mine (mainly for detecting the pressure from the top wall of the mine) and an alarm unit 2200 for feeding back the detection results of the pressure detection unit 2100 need to be set in the detection component 2000.

[0064] It should be noted that in the actual application of the present invention, the pressure detection unit 2100 can be set on the gasket 1202 in the side pushing unit 1200, so as to accurately detect the pressure on the side wall of the mine.

[0065] (Two - One)

[0066] The pressure detection unit 2100 includes a pressure sensor 2101 and a flexible block 2102. A group of flexible blocks 2102 are symmetrically distributed on the side wall surfaces of the upper ends of the cross arm 1101 and the first connecting rod 1103. Pressure sensors 2101 are buried in the flexible blocks 2102. This is because the inner wall of the mine is not completely flat (but uneven). Therefore, in order to protect the pressure sensor 2101 from being damaged by the sharp edges on the inner wall of the mine, the flexible block 2102 is needed to wrap the pressure sensor 2101, so as to avoid the direct contact between the pressure sensor 2101 and the inner wall of the mine.

[0067] It should be noted that: the position of the flexible block 2102 on the cross arm 1101 and the first connecting rod 1103 is not fixed, but the worker can adjust the position of the flexible block 2102 on the cross arm 1101 and the first connecting rod 1103 according to the actual shape of the inner wall of the mine, so that the pressure sensor 2101 can be fully squeezed by the inner wall of the mine.

[0068] Any two pressure sensors 2101 are in a parallel relationship, and indicator lights 2103 corresponding to the pressure sensors 2101 one by one are arranged on the side wall surfaces at the lower ends of the cross arm 1101 and the first connecting rod 1103; the pressure sensors 2101, warning lights 2201, speakers 2202 and indicator lights 2103 are all powered by an external power supply and controlled by a control center outside the mine. In this way, the control center can correspondingly adjust the color of the indication according to the monitoring value on the pressure sensor 2101. When the monitoring value on the pressure sensor 2101 is normal, the indicator light 2103 emits green. When the monitoring value on the pressure sensor 2101 is abnormal, the indicator light 2103 emits red; and the control center will also send a reminder to the workers in the mine through the alarm unit 2200.

[0069] (Two-two)

[0070] The alarm unit 2200 includes a warning light 2201 and a speaker 2202 arranged on the fixed rod 1105.

[0071] Among them, the warning light 2201 and the speaker 2202 are used to give an audible and visual alarm. Thus, when the environment in the mine is not conducive to work, the control center can use the warning light 2201 and the speaker 2202 to send an alarm to the workers in the mine and help the workers evacuate in time. (Three)

[0073] A lighting lamp 3000, an air quality monitor 4000 and a life detector 5000 are arranged on the fixed rod 1105; among them, the lighting lamp 3000 provides light sources for the workers in the mine, the air quality monitor 4000 is used to monitor the air quality of each section in the mine (including but not limited to oxygen concentration, gas concentration, carbon dioxide concentration, etc.), and the life detector 5000 is used to monitor whether there are trapped people in the mine during a collapse to help the rescue workers carry out rapid real-time rescue.

[0074] A PLC controller 6000 for controlling the lighting lamp 3000, the air quality monitor 4000 and the life detector 5000 is also arranged on the fixed rod 1105. The PLC controller 6000, the lighting lamp 3000, the air quality monitor 4000 and the life detector 5000 are all powered by an emergency storage battery 7000 arranged on the fixed rod 1105.

[0075] The PLC controller 6000 is controlled by a control center located outside the mine, and the PLC controller 6000 has an independent identification number in the control system of the control center. The PLC controller 6000 is built-in with a wireless communication module 6001 and a positioning module 6002; a wireless intercom 6003 is integrated on the PLC controller 6000, and the keys 6004, microphone 6005 and speaker 6006 of the wireless intercom 6003 are all arranged on the outer surface of the housing of the PLC controller 6000. In this way, when a collapse occurs in the mine, the trapped personnel can contact the control center outside the mine through the wireless intercom 6003, so as to help the rescue personnel quickly locate the position and specific situation of the trapped personnel for rescue.

[0076] It should be noted that: the PLC controller 6000 inside the mine can transmit information to an adjacent PLC controller 6000, and then the adjacent PLC controller 6000 transmits the information to the control center outside the mine in a relay transmission manner.

[0077] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
