Technical Field

[0002] In modern mining production, mine safety monitoring is an important link to ensure the safety of workers and the smooth progress of production. The underground mine intelligent dispatching communication terminal is an intelligent device used for mine safety monitoring. It is mainly used for internal mine security. It can detect harmful gases, temperature, humidity and other safety indicators in the mine, and issue timely alarms to ensure the safety of workers. Traditional underground mine intelligent dispatching communication terminals usually rely on the direct connection between the ground host and the detection sensor in the auxiliary tunnel.

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. Example

[0025] In view of the problems raised in the background technology, this embodiment provides an intelligent scheduling communication terminal, such as Figure 1-5 As shown, it includes a background host installed in a ground machine room and a mother machine installed in the main lane. The mother machine is connected to the background host by wire. A storage compartment is provided in the mother machine. A plurality of crawler sub-machines are stored in the storage compartment. The crawler sub-machines are wirelessly connected to the mother machine. The background host can control each crawler sub-machine to execute instructions through the mother machine. The background host can control the movement of each crawler sub-machine through the mother machine to perform safety inspections on the secondary lanes.

[0026] The crawler submachine includes a frame 11 with a crawler moving mechanism 2 installed, a submachine controller, an audio communication module, a side extension detection device 3 and a power supply. The power supply is connected to the submachine controller and is used to provide power to the submachine controller and components connected to the submachine controller. The crawler moving mechanism 2 is connected to the submachine controller. The submachine controller can drive the frame 1 to move through the crawler moving mechanism 2. The crawler moving mechanism 2 is an existing structure and will not be described in detail here. The submachine controller is wirelessly connected to the mother machine. Wireless transceiver modules are deployed on the submachine controller and the mother machine controller. The submachine controller and The mother machine is wirelessly connected through two wireless transceiver modules. When the background host and the crawler sub-machine communicate with each other, a wired connection is used between the mother machine and the background host, which ensures the stability and high speed of the trunk communication line. A wireless connection is used between the crawler sub-machine and the mother machine, which can flexibly respond to changes inside the secondary lane, realizing the complementary advantages of wired and wireless communications. In addition, the mother machine, as a relay station for wireless signals, can significantly enhance the strength of signal transmission between the crawler sub-machine and the background host, reduce signal attenuation or loss caused by the complex environment of the secondary lane, and thus improve the stability of the entire communication.

[0027] The audio communication module is installed on the vehicle frame and connected to the sub-machine controller. The audio communication module is used for real-time voice communication, enabling staff to conduct real-time voice communication inside the mine and on the ground, thereby improving coordination efficiency and emergency response speed.

[0028] The side extension detection device 3 includes a split carrier frame 44, a support frame 55, an opening and closing control mechanism, a camera and a detection module 7. The split carrier frame 4 is fixedly installed on the vehicle frame, and the support frame 5 is horizontally installed in the split carrier frame 4 in a closed state through the opening and closing control mechanism, and the top of the support frame 5 is arranged toward the open side of the split carrier frame 4; the top of the support frame 5 extends forward from the split carrier frame 4 in a closed state, and is installed with a camera connected to the sub-machine controller. The background host can obtain real-time shooting data of the camera through the mother machine, and control the crawler moving mechanism 2 to drive the vehicle frame 1 to move according to the real-time shooting data; the opening and closing control mechanism is connected to the sub-machine controller, and the sub-machine controller can control the split carrier frame 4 to open through the opening and closing control mechanism to drive the support frame 5 to stand upright and extend out of the split carrier frame 4; The split load-bearing frame 4 includes an upper shell frame 41 and a lower shell frame 42 that are split apart, the tail ends of the upper frame shell and the lower frame shell are both rotatably mounted on a fixed shaft 43, and the lower frame shell is fixedly installed on the frame 1; the support frame 5 is arranged between the upper shell frame 41 and the lower shell frame 42, and the front and rear ends of the upper shell frame 41 and the lower shell frame 42 are both provided with notches 44 matching the support frame 5, the bottom end of the support frame 5 passes through the notches 44 at the tail ends of the upper frame shell and the lower frame shell, and is rotatably mounted on the fixed shaft 43; the top end of the support frame 5 passes through the notches 44 at the front ends of the upper shell frame 41 and the lower shell frame 42 and extends out of the load-bearing frame; the support frame 5 is designed to be open at both ends facing the upper frame shell and the lower frame shell; the opening and closing control mechanism is installed in the support frame 5, and is connected to the lower frame shell and the upper frame shell through the openings of the support frames 5 on the left and right sides respectively.

[0029] The opening and closing control mechanism includes a lifting drive assembly 61, a lifting platform 62 and a connecting rod 63. The lifting platform 62 is matched and installed in the support frame 5 through the lifting drive assembly 61. The lifting drive assembly 61 is connected to the sub-machine controller. The sub-machine controller can control the lifting platform 62 to rise and fall along the support frame 5 through the lifting drive assembly 61. Specifically, the lifting drive assembly 61 includes a screw rod 64 rotatably installed in the support frame 5. The top of the screw rod 64 is rotatably connected to a drive motor 65. The drive motor 65 is connected to the sub-machine controller. There are many ways to rotatably install the screw 64, such as: Figure 4 As shown, two platform plates 51 are vertically spaced inside the support frame 5, a screw rod 64 is arranged between the two platform plates 51, and the upper and lower ends of the screw rod 64 are rotatably mounted on the platform plate 51 on the same side through bearings, and a drive motor 65 is fixedly mounted on the upper platform plate 51 and is transmission-connected to the screw rod 64. When the drive motor 65 is working, it will drive the screw rod 64 to rotate synchronously.

[0030] A threaded hole matching the screw rod 64 is provided in the middle of the lifting platform 62, and the lifting platform 62 is fitted onto the screw rod 64. The left and right end surfaces of the lifting platform 62 respectively contact the inner wall of the support frame 5. When the screw rod 64 rotates, the left and right end surfaces of the lifting platform 62 are constrained by the inner wall of the support frame 5 and will not rotate. Therefore, the rotation of the screw rod 64 will drive the lifting platform 62 to rise and fall along the support.

[0031] The lifting platform 62 is symmetrically hingedly installed with connecting rods 63 on the two end surfaces facing the upper shell frame 41 and the lower shell frame 42. The bottom end of the connecting rod 63 is tilted and extends into the shell frame on the same side and is hinged with the shell frame on the same side. When the lifting platform 62 moves downward along the support frame 5, it will drive the support frame 5 to drive the upper frame shell to rotate backward around the fixed axis 43 at a differential speed, and when the upper frame shell is flipped backward around the fixed axis 43 to a horizontal state, the support frame 5 is in an erect state. The detection module 7 is matched and installed in the support frame 5, and is used to detect the air quality of the secondary lane when the support frame 5 is erected and extended to the split carrier frame 4. The background host obtains the detection data of the crawler sub-machine detection module 7 of each secondary lane through the mother machine. Specifically: The rotation speed of the upper frame shell is twice the rotation speed of the support frame 5. When the split load frame 4 is in a closed state, the bottom end of the connecting rod 63 is set toward the rear end of the split load frame 4, and in this state, the angle between the connecting rod 63 and the frame shell on the same side is greater than 5°, which is convenient for controlling the opening and closing of the split load frame 4. When the lifting platform 62 is driven to move downward along the support frame 5 by the lifting drive assembly 61, the connecting rod 63 close to the lower frame shell side will use the bottom end as a fulcrum to push the support frame 5 upward and rotate it to the rear side around the fixed axis 43 to stand upright. During this process, the connecting rod 63 connected to the upper frame shell will use the end connected to the lifting platform 62 as a fulcrum to push the upper frame shell to rotate synchronously around the fixed axis 43 to the rear side. Since the rotation speed of the upper frame shell is twice the rotation speed of the support frame 5, when the upper frame shell is flipped backward to a horizontal state around the fixed axis 43, the support frame 5 is in an upright state, thereby raising the height of the detection module 7. At this time, the side expansion detection device 3 is in a detection expansion state.

[0032] The detection module 7 is installed in the support frame 5 above the opening and closing control mechanism. The support frame 5 above the lifting drive assembly 61 is matched with a platform 52, and the detection module 7 is matched with the platform 52. The detection module 7 includes a sensor array installed on the base, and the sensor array is controlled and connected to the sub-machine controller. The sub-machine controller controls the opening and closing of the sensor array according to the received instructions and receives the detection data transmitted by the sensor array and sends it to the main machine. When the side expansion detection device 3 is in the detection expansion state, the sub-machine controller controls the sensor array to start air detection.

[0033] The sensor array includes an air quality sensor, a harmful gas sensor, a temperature and humidity sensor, and a dust sensor installed on the base. The air quality sensor, the harmful gas sensor, the temperature and humidity sensor, and the dust sensor are all connected to the slave controller. The air quality sensor is used to detect the oxygen concentration, carbon dioxide concentration, etc. The harmful gas sensor is used to detect the concentration of harmful gases such as carbon monoxide (CO), hydrogen sulfide (H2S), and methane (CH4). The temperature and humidity sensor is used to monitor the temperature and humidity of the environment and provide comprehensive environmental data. The dust sensor is used to detect the concentration of dust in the air and evaluate the hazards of mine dust.

[0034] When the intelligent dispatching communication terminal provided in this embodiment is in use, the background host sends a task instruction to the mother machine through a wired connection according to the position of the secondary lane that needs to be detected; after receiving the instruction, the mother machine releases the corresponding number of crawler sub-machines from the storage bin and sends instructions to them wirelessly. The crawler sub-machines move to the designated secondary lanes according to the predetermined path in the instruction and avoid obstacles according to the real-time shooting data of the camera. After reaching the target position, the sub-machine controller of the crawler sub-machine activates the side extension detection device 3 according to the instruction, so that the support frame 5 is erected and extended out of the split carrier frame 4, and the detection module 7 starts to work. The detection module 7 collects environmental data, such as air quality, harmful gas concentration, etc., and transmits it to the mother machine through the sub-machine controller, and then forwarded to the background host by the mother machine; through the audio communication module, the ground command center can have real-time dialogue with the staff in the lane to ensure smooth communication, and the ground command center can observe the situation in each lane in real time through the cameras on each crawler sub-machine. After the detection task is completed, the crawler sub-machine automatically retracts the support frame 5 and returns to the mother machine along the original route to stand by or wait for further instructions. The opening and closing of the open carrier frame can effectively protect the detection module 7. Example

[0035] The difference between Example 2 and Example 1 is that Figure 6 As shown, a telescopic cylinder 53 is vertically installed on the platform 52, and the telescopic cylinder 53 is in a normally retracted state. The detection module is matched and installed on the top of the telescopic cylinder 53, and the top of the support frame on the detection module is matched with a window. An air supply cylinder is installed in the support frame below the lifting platform, and the piston rod of the air supply cylinder is connected to the lifting platform. The air supply cylinder is an existing double-acting cylinder, and the lower chamber of the air supply cylinder is connected to the air inlet of the telescopic cylinder through an air pipe. When the lifting platform descends, the piston rod of the air supply cylinder will be pushed to retract inward, thereby driving the piston of the air supply cylinder to move downward, squeezing the air in the lower chamber of the air supply cylinder into the telescopic cylinder 53, so that the telescopic cylinder 53 drives the detection module to lift upward, pass through the window and extend out of the support frame, thereby further increasing the height of the detection module when the split carrier frame is opened. Example

[0036] The difference between Example 3 and Example 2 is that Figure 6As shown, the upper end surface of the upper shell frame 4 is matched with a support leg 411. When the upper shell frame 4 rotates backward around the fixed axis 43 to fully open the split carrier frame, the support leg will follow the upper shell frame 41 to rotate backward around the fixed axis 43 and come into contact with the ground of the tunnel, thereby supporting the suspended upper shell frame 4. Example

[0037] The difference between Example 4 and Example 3 is that Figure 7 As shown, the upper end surface of the upper shell frame 4 is matched with a negative pressure bellows 81 with an open top. When the upper shell frame 4 rotates backward around the fixed axis 43 to fully open the split carrier frame, the negative pressure bellows will rotate backward around the fixed axis 43 synchronously with the upper shell frame 41 to contact with the tunnel ground, and the opening of the negative pressure bellows will be blocked by the tunnel ground; the support leg 411 is located in the negative pressure bellows, and an energy storage component is provided between the negative pressure bellows and the upper chamber of the air supply cylinder, specifically: the energy storage component The energy storage component comprises an energy storage shell 82 with a piston cavity therein, an energy storage piston 83 is matched and installed in the energy storage shell, and an energy storage spring 84 is matched and installed in the energy storage shell below the energy storage piston 83. The energy storage spring will push the energy storage piston upward and contact the top wall of the energy storage shell in a natural state; the energy storage shell is provided with two air holes connected to the piston cavity below the energy storage piston, the air hole a821 is connected to the upper chamber of the air supply cylinder 9 through the air pipe, and the air hole b822 is connected to the inner air of the negative pressure corrugated cover through the air pipe. The air pipe between the air hole b and the negative pressure bellows is matched with a pressure control valve 85 connected to the sub-machine controller. The pressure control valve 85 is in a normally closed state. During the unfolding process of the split carrier, the piston in the air supply cylinder 9 will move downward synchronously with the platform plate, and the air in the piston chamber below the energy storage piston in the energy storage assembly will be extracted to compensate for the air in the upper chamber of the air supply cylinder, driving the energy storage piston to move downward to squeeze the energy storage spring for energy storage. When the split carrier is fully unfolded, that is, when the negative pressure bellows will rotate backward around the fixed axis 43 synchronously with the upper shell frame 41 and come into contact with the roadway ground, and after the opening of the negative pressure bellows is blocked by the roadway ground, the sub-machine controller controls the pressure control valve to open, so that the internal space of the negative pressure bellows is connected with the piston chamber of the energy storage shell on the lower side of the energy storage piston, and the squeezed energy storage spring will push the energy storage piston upward to move upward instantly, extracting the air inside the negative pressure bellows to generate negative pressure and be sucked together with the roadway ground, thereby fixing the position of the sub-machine. Example

[0038] The difference between Example 5 and Example 4 is that Figure 7 As shown, a threaded hole communicating with the interior of the energy storage shell 82 is vertically provided on the top of the energy storage shell, and a pressure-adjusting bolt 86 is matched and installed in the threaded hole. The compression degree of the energy storage spring in the initial state can be adjusted by controlling the penetration length of the pressure-adjusting bolt through the knob, thereby controlling the suction strength of the negative pressure bellows. Example

[0039] The difference between Example 6 and Example 4 is that Figure 7 As shown, a plurality of hollow tubes are vertically installed on the base of the detection module 7 at the top of the telescopic cylinder 53. The number of the hollow tubes is the same as the number of sensors in the sensor array. The sensors in the sensor array are respectively installed in the corresponding hollow tubes, and a protective net is installed on the top of the hollow tube to prevent falling rocks from falling into the hollow tube and hitting the sensor; a through hole is provided at the bottom end of the hollow tube and is connected to a negative pressure tube, and the other end of the negative pressure tube is connected to a one-way air extraction valve 10, and the suction end of the one-way air extraction valve is connected to the air pipe connecting the pressure control valve and the negative pressure bellows through an air pipe, and the opening negative pressure of the one-way air extraction valve is a, and the negative pressure bellows is in contact with the ground The minimum negative pressure for solid absorption is b, and the energy storage pressure of the energy storage component when the split carrier is fully opened is c, wherein c>a>b. Therefore, during use, when the pressure control valve is opened after the split carrier is unfolded, the energy storage component in the energy storage state will simultaneously suck the air in the hollow tube and the negative pressure bellows. When the air in the hollow tube is sucked, the air in the tunnel will be sucked into the hollow tube through the top of the hollow tube, so that the sensor in the hollow tube can be isolated and detected separately. Moreover, since c>a>b, as the energy storage component is reset, the one-way air extraction valve will be closed first, so as to ensure that the negative pressure is sufficient to support the solid absorption of the negative pressure bellows and the ground.

Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
