Description

Technical Field

[0001] The invention belongs to the technical field of fire prevention and control in coal mine goafs, and in particular provides a device and a method for quickly laying bundle pipes in coal mine goafs. Background Art

[0002] my country's energy structure is mainly coal-based, and coal production must meet the needs of national economic and social development. Due to geographical restrictions, my country's coal production mainly adopts underground mining. Once a disaster occurs underground, it is much more difficult to deal with than on the ground. Therefore, it is particularly important to implement a series of preventive measures in coal mines.

[0003] The five major disasters faced by coal mines include: gas disasters, floods, fires, roof falls and mine dust disasters. Fires will not only destroy a large number of equipment and coal resources, but may also cause secondary disasters such as gas and coal dust explosions, while generating high-temperature smoke and toxic and harmful gases, seriously threatening the lives of underground workers. Once a fire occurs underground in a coal mine, it will bring huge losses to enterprises, society and even the country. For coal mines, when the mined coal seams have the characteristics of spontaneous combustion, especially in the top coal mining method, the amount of coal left in the goaf is large. If there is air leakage, these remaining coals will gradually heat up and store heat under oxidation, and may eventually cause spontaneous combustion, leading to fires in the goaf. By studying the spontaneous combustion process of the remaining coal in the goaf, it is found that it is a gradual development process. According to the differences in temperature and gas content caused by the heat storage and heat release of the remaining coal in different areas of the goaf, the goaf can be divided into three natural "zones": heat dissipation zone, oxidation warming zone and asphyxiation zone. Accurately understanding the distribution of the natural "three zones" in the goaf is crucial for determining whether there is a fire hazard underground in a coal mine, predicting fire risks, and implementing fire prevention and extinguishing measures.

[0004] At present, the division of the natural "three zones" in the goaf mainly relies on measuring the gas content and temperature in different areas of the goaf. The specific method is to lay bundle pipes and temperature measuring wires in the goaf to collect gas and detect temperature. Usually, bundle pipes and temperature measuring wires are laid in the air intake or return air lane of the coal mining face. During the process, the bundle pipes and temperature measuring wires pre-wound on the ground need to be passed through the steel pipe in turn and connected section by section. As the length of the steel pipe increases, the total resistance of the bundle pipe and the temperature measuring wire through the steel pipe gradually increases, which requires continuous increase in pulling force until the laying is completed. The entire process relies entirely on manpower, requires the participation of more people, and is time-consuming and labor-intensive. Summary of the invention

[0009] When the working unit is in the initial state, the output shaft of the motor is in the extended state, and the driving gear on the motor and the linkage gear in the roller mechanism are respectively separated from the transmission gear in the transmission wheel mechanism; at this time, the motor, the reducer and the double rocker device are in the connected state, the end of the threading tube is passed through the fixed hole and fixed on the roller, and the threading tube is rolled up on the outer peripheral surface of the roller; when the threading tube is transported, the front end of the threading tube is passed between the upper roller ring and the lower roller ring, and the proportional pneumatic pressing device is activated, and the upper roller ring and the lower roller ring clamp the threading tube; start the motor and make the motor rotate forward, and transmit the power to the double rocker device through the reducer, and the upper roller ring and the lower roller ring of the double rocker device drive the transmission of the threading tube through rotation;

[0010] When the threading tube is recovered, the output shaft of the motor is in a retracted state, and the driving gear on the motor is meshed with the transmission gear in the transmission wheel mechanism. At the same time, the position of the roller support connecting beam of the roller mechanism is moved to make the linkage gear mesh with the transmission gear, and then the roller support connecting beam is fixed to the chassis. At this time, the transmission gear of the transmission wheel mechanism is meshed with the driving gear on the motor and the linkage gear in the roller mechanism; the end of the threading tube is taken out from the fixing hole, and taken out from the upper roller ring and the lower roller ring, and then the end of the threading tube is fixed on the roller through the fixing hole again; the motor is started and reversed, and the roller is reversed through the transmission of the driving gear, the transmission gear and the linkage gear, so that the threading tube is rolled up on the outer circumference of the roller.

[0018] Furthermore, a connecting hole for installing a detection pipeline is provided on the side end surface of the chassis.

[0019] The present invention also provides a method for quickly laying bundled pipes in a coal mine goaf area, and applies the device for quickly laying bundled pipes in a coal mine goaf area. The construction process is as follows:

[0020] Step 1: Prepare the pipeline bundle on the ground for laying in the detection pipeline:

[0021] Several detection points are set in the detection pipeline, and the distance between each detection point is L;

[0022] The detection pipeline includes a plurality of detection tubes, a plurality of tees, a plurality of flanges and a plurality of connecting bolts. A tee is installed between two adjacent detection tubes through flanges and connecting bolts, and a tee is also installed on the front end surface of the frontmost detection tube through flanges and connecting bolts. The number of tees is the same as the number of detection points and corresponds to the positions of the detection points.

[0023] A pipe bundle is manufactured according to the position and number of detection points to be set in the detection pipeline. The pipe bundle includes several groups of pipe bundle monomers of different lengths. The number of pipe bundle monomers is the same as the number of detection points. Each group of pipe bundle monomers includes a bundle tube, a temperature measuring wire and a temperature sensor. The ends of the bundle tube and the temperature measuring wire are aligned and placed in parallel. The front end of the temperature measuring wire is indented by a distance L5 from the front end of the bundle tube. The front end of the temperature measuring wire is installed with a temperature sensor. After the ends of each group of pipe bundle monomers are aligned, they are tied together from the end to the front end along the length direction of each group of pipe bundle monomers to form a pipe bundle; wherein, in each group of pipe bundle monomers, a non-binding section with a length of L1 is provided from the front end of the bundle tube to the rear, that is, in the non-binding section, the bundle tube and the temperature measuring wire are not tied and fixed with glass tape; at the same time, a binding section with a length of L2 is provided at the end of each group of pipe bundle monomers for binding with the lead-in tube; the length difference between two adjacent groups of pipe bundle monomers is L;

[0024] Step 2: Downhole detection pipeline connection:

[0025] In the underground coal mining working face tunnel, each detection pipe and each tee and flange in the detection pipeline are connected, and one end of the detection pipeline with a tee at the front end is close to the goaf, and the other end is far away from the goaf;

[0026] Step 3: Lay the lead pipe in the test pipeline:

[0027] The pipeline bundles and the quick laying device for the bundled pipes in the coal mine goaf prepared on the ground are lowered together into the tunnel of the coal mining working face, the working unit is transported to the end of the detection pipeline by the mobile unit, and then the working unit is taken off the mobile unit with the help of a handle and placed next to the detection pipeline; the output shaft of the motor is in an extended state and separated from the transmission gear in the transmission wheel mechanism, and at the same time, the position of the roller support connecting beam of the roller mechanism is moved away from the tool box to separate the linkage gear from the transmission gear, and then the roller support connecting beam is fixed to the chassis; at this time, the transmission gear of the transmission wheel mechanism is separated from the driving gear on the motor and the linkage gear in the roller mechanism;

[0028] Connect the detection tube at the end of the detection pipeline to the connection hole on the chassis through the flange and the connecting bolts to prevent the pipeline or the working unit from moving when the working unit pushes the guide tube into the detection pipeline, thereby increasing the pushing resistance. After the connection is completed, connect the forward air duct interface on the motor to the air supply pipeline in the lane through the air duct; then manually pass the front end of the guide tube on the drum through the inverted U-shaped guide buckle, between the upper roller ring and the lower roller ring, and the guide tube in turn and send it into the detection tube connected to the chassis;

[0029] The proportional pneumatic pressing device is activated, the upper roller ring and the lower roller ring clamp the threading tube, the motor is started to rotate forward, and the power is transmitted to the double rocker device through the reducer. The upper roller ring and the lower roller ring of the double rocker device drive the threading tube to be transported by rotation. At this time, the roller rotates forward with the transportation of the threading tube, realizing the continuous transportation of the threading tube in the detection pipeline;

[0030] Step 4: After the guide tube is delivered to the right place, adjust the motor output shaft to the retracted state, so that the driving gear on the motor is meshed with the transmission gear of the transmission wheel mechanism. At the same time, move the position of the roller support connecting beam, so that the linkage gear in the roller mechanism is meshed with the transmission gear, and then fix the roller support connecting beam to the chassis;

[0031] Then, the end of the guide tube is taken out from the fixing hole, and gradually withdrawn from the inverted U-shaped guide buckle, between the upper roller ring and the lower roller ring, and the guide tube. Then, the end of the guide tube is fixed in the fixing hole on the roller again, so that the guide tube loses the constraint of the guide tube, the upper roller ring, the lower roller ring and the inverted U-shaped guide buckle.

[0032] Step 5: Connect the binding section of the prepared pipe bundle to the front end of the guide tube in the detection pipeline;

[0033] Step 6: Recover the lead pipe and lay the pipe bundle in the detection pipeline:

[0034] Connect the reversing air duct interface on the motor to the air supply pipeline in the lane through the air duct, then start the motor and reverse it. At this time, the driving gear, transmission gear and linkage gear drive the drum to reverse, and the threading pipe is rolled up on the outer surface of the drum. During the continuous rotation of the drum, the threading pipe will pull the pipe bundle into the detection pipeline until the laying of the pipe bundle in the detection pipeline is completed. Then, the motor is turned off and the recovery of the threading pipe is stopped.

[0035] Step 7: After the threading pipe is recovered, each bundle tube and temperature measuring wire in the pipeline bundle are found one by one through each tee, and then the flower tube is installed on each tee, and each bundle tube and each temperature sensor is fixed in each flower tube;

[0036] Step 8: Check whether each bundle tube is transparent and check the initial resistance of each temperature sensor;

[0037] Step 9. Transfer or recover the quick laying device for bundled pipes in the goaf of coal mines: release the connection between the working unit and the detection pipeline and the air supply pipeline, lift the working unit onto the mobile unit, and then transfer or recover it.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] (1) The device for quickly laying bundle pipes in coal mine goaf of the present invention comprises a moving unit and a working unit. The working unit is moved underground by the moving unit, and is flexible and convenient to operate. The working unit realizes the laying of the pipe bundle in the underground detection pipeline by setting a motor, a reducer, a double rocker arm device, a roller mechanism and a transmission wheel mechanism, thereby reducing the number of workers, effectively reducing the work intensity and improving the work efficiency.

[0040] (2) The motor and roller mechanism in the device for quickly laying bundle pipes in the goaf of a coal mine of the present invention can be moved and disassembled and installed on the chassis. First, the motor drives the double rocker arm device to transport the guide pipe into the underground detection pipeline, and then the guide pipe is fixed to the pipeline bundle. By moving the position of the motor and the roller mechanism, the driving gear on the motor, the linkage gear in the roller mechanism and the transmission gear of the transmission wheel mechanism are engaged to realize transmission, so that the guide pipe is recovered, and the pipeline bundle is driven to be laid in the detection pipeline, and each bundle pipe and each temperature sensor in the pipeline bundle is made to correspond to the position of each detection point of the detection pipeline.

[0041] (3) In the process of conveying the guide tube, the present invention uses a guide tube and an inverted U-shaped guide buckle to limit the conveying direction of the guide tube. The front end of the guide tube of the present invention is conical and is made of a material with light weight, high corrosion resistance, strong plasticity and certain bending resistance, so that it is more convenient to move in the detection pipeline.

[0042] (4) The motor in the device for quickly laying bundle pipes in coal mine goaf of the present invention can be a pneumatic motor, which does not require a preset power supply line, and the operation process is safer and more reliable. In addition, the device of the present invention has a simple structure, is easy to disassemble and move, and has a simple operation method, which is convenient for large-scale promotion and application underground.

A tee 4300 is installed between two adjacent detection tubes 4100 via a flange 4200 and a connecting bolt 4500, and a tee 4300 is also installed on the front end surface of the frontmost detection tube 4100 via a flange 4200 and a connecting bolt 4500. The number of tees 4300 is the same as the number of detection points and corresponds to the positions of the detection points.

[0091] The pipeline bundle is manufactured according to the position and number of the detection points to be set in the detection pipeline. The pipeline bundle 3000 includes a plurality of pipeline bundle monomers of different lengths. The number of pipeline bundle monomers is the same as the number of detection points. Figure 8 As shown, each group of pipe harness monomers includes a bundle tube 3001, a temperature measuring wire 3002 and a temperature sensor 3003. The ends of the bundle tube 3001 and the temperature measuring wire 3002 are aligned and placed in parallel. The front end of the temperature measuring wire 3002 is retracted by a distance L5 from the front end of the bundle tube 3001 to facilitate the installation of the temperature sensor 3003. The front end of the temperature measuring wire 3002 is installed with the temperature sensor 3003. After the ends of the bundle tube monomers of each group are aligned, the bundle tube 3001 and the temperature measuring wire 3002 are automatically connected along the length direction of each bundle tube monomer. The end is bound and fixed to the front end by glass tape 5000 to form a pipe bundle 3000; wherein, in each group of pipe bundle monomers, a non-binding section with a length of L1 is provided from the front end of the bundle tube 3001 to the rear, that is, in the non-binding section, the bundle tube 3001 and the temperature measuring wire 3002 are not bound and fixed by glass tape 5000; at the same time, a binding section with a length of L2 is provided at the end of each group of pipe bundle monomers for binding with the lead-in tube 2406; the length difference between two adjacent groups of pipe bundle monomers is L;

[0092] Step 2: Connect the underground detection pipeline: Connect the detection pipeline in the underground coal mining working face tunnel. The front end of the detection pipeline has a tee 4300, one end is close to the goaf, and the other end is far away from the goaf;

[0093] Step 3: Lay the lead pipe 2406 in the detection pipeline:

[0094] The pipeline bundle 3000 prepared on the ground and the quick laying device for the bundle pipe in the coal mine goaf are lowered into the tunnel of the coal mining face, and the working unit is transported to the end of the detection pipeline (that is, the detection pipeline is located at the end away from the goaf) by the mobile unit, and then the working unit is removed from the mobile unit by means of the handle 2002 and placed next to the detection pipeline, and the working unit is checked to ensure that it is in the initial state. At this time, the transmission gear 2500 of the transmission wheel mechanism and the driving gear 2104 on the motor 2100 and the linkage gear 2404 in the roller mechanism are in a separated state;

[0095] like Figure 6 As shown, the detection tube 4100 at the end of the detection pipeline is connected to the chassis 2001 through the flange 4200 and the connecting bolt 4500 (when connecting, the bottom hole of the flange 4200 on the detection tube 4100 is connected to the connecting hole 2004 on the chassis 2001) to prevent the pipeline or the working unit from moving when the working unit pushes the guide tube 2406 into the detection pipeline and increasing the pushing resistance. After the connection is completed, the forward air duct interface 2101 on the motor 2100 is connected to the air supply pipeline in the lane through the air duct; at this time, the front end of the guide tube 2406 on the roller 2400 is manually passed through the inverted U-shaped guide buckle 2003, between the upper roller ring 2302 and the lower roller ring 2303, and the guide tube 2304 in turn and sent into the detection tube 4100 connected to the chassis 2001;

[0096] The proportional pneumatic pressing device 2301 is activated, the upper roller ring 2302 and the lower roller ring 2303 clamp the threading tube 2406, the motor 2100 is started to rotate forward, and the power is transmitted to the double rocker device 2300 through the reducer 2200. The upper roller ring 2302 and the lower roller ring 2303 of the double rocker device 2300 drive the threading tube 2406 to be transported by rotation. At this time, the roller 2400 rotates forward with the transportation of the threading tube 2406, so as to realize the continuous transportation of the threading tube 2406 in the detection pipeline;

[0097] Step 4: Figure 7 As shown, adjust the position of the motor 2100 and the roller 2400 so that the transmission gear 2500 of the transmission wheel mechanism is in meshing state with the driving gear 2104 on the motor 2100 and the linkage gear 2404 in the roller mechanism, and reconnect the guide tube 2406 to the roller 2400:

[0098] After the threading tube 2406 is delivered to the position, the output shaft of the motor 2100 is adjusted to be in a retracted state, so that the driving gear 2104 on the motor 2100 is meshed with the transmission gear 2500 in the transmission wheel mechanism. At the same time, the position of the roller support connecting beam 2407 of the roller mechanism is moved so that the linkage gear 2404 is meshed with the transmission gear 2500, and then the roller support connecting beam 2407 is fixed to the chassis 2001; at this time, the transmission gear 2500 of the transmission wheel mechanism is in a meshing state with the driving gear 2104 on the motor 2100 and the linkage gear 2404 in the roller mechanism;

[0099] Then, the end of the guide tube 2406 is taken out from the fixing hole 2405, and gradually withdrawn from the inverted U-shaped guide buckle 2003, between the upper roller ring 2302 and the lower roller ring 2303, and the guide tube 2304, and then the end of the guide tube 2406 is fixed to the fixing hole 2405 on the roller 2400 again, so that the guide tube 2406 loses the constraint of the guide tube 2304, the upper roller ring 2302, the lower roller ring 2303 and the inverted U-shaped guide buckle 2003, and the guide tube 2406 is rolled up and wound on the roller 2400;

[0100] Step 5: Connect the binding section of the prepared pipe bundle 3000 to the front end of the guide tube 2406 in the detection pipeline through glass tape or wear-resistant and tough thin wire;

[0101] Step 6: Recover the threading tube 2406 and lay the pipeline bundle 3000 in the detection pipeline:

[0102] Connect the reversing air duct interface 2102 on the motor 2100 to the air supply pipeline in the lane through the air duct, then start the motor 2100 and reverse the motor 2100. At this time, the driving gear 2104, the transmission gear 2500 and the linkage gear 2404 drive the roller 2400 to reverse, and the threading tube 2406 is rolled up on the outer peripheral surface of the roller 2400. During the continuous rotation of the roller 2400, the threading tube 2406 will pull the pipe bundle 3000 into the detection pipeline until the laying of the pipe bundle 3000 in the detection pipeline is completed, and then the motor 2100 is turned off to stop the recovery of the threading tube 2406.

[0103] Step 7: Reference Fig.10 After the threading tube 2406 is recovered, each bundle tube 3001 and each temperature measuring wire 3002 in the pipeline bundle 3000 are found one by one through each tee 4300, and then the flower tube 4400 is installed on each tee 4300 (the flower tube 4400 is installed at the top of the vertical pipe of the tee 4300 through the flange 4200 and the connecting bolt 4500), and each bundle tube 3001 and each temperature sensor 3003 are respectively fixed in each flower tube 4400;

[0104] Step 8: Check whether each bundle tube 3001 is transparent and check the initial resistance of each temperature sensor 3003: Use a portable negative pressure extractor to check whether each bundle tube is transparent again to avoid bundle tube blockage and affect the subsequent gas component detection; at the same time, use a multimeter to measure and record the initial resistance value of each temperature sensor;

[0105] Step 9: Transfer or recover the quick laying device of bundled pipe in coal mine goaf:

[0106] The connection between the working unit and the detection pipeline and the air supply pipeline is released, and the working unit is lifted and placed on the mobile unit for transfer or recovery. Then, as the coal mining face continues to advance, the gas entering each detection point in the goaf is detected every day, the resistance value is obtained through the temperature sensor, and the gas is collected through the bundle tube. The range of the three spontaneous combustion zones in the goaf is determined by calculating its temperature change and monitoring its gas composition.

[0120] In this embodiment, the bundle tube 3001 is a hollow tube with a diameter of 8 mm for mining. The temperature measuring wire 3002 is a two-wire wire, and the temperature sensor 3003 is a pt100 temperature sensor. The bundle tube 3001 and the temperature measuring wire 3002 in each group of pipe bundle monomers are in different colors for easy identification.

[0121] L1=0.3m-0.5m, L2=0.5m-2.5m, L5=0.1m-0.2m;

[0122] Step 2: Connect the underground detection pipeline: Connect the detection pipeline in the underground coal mining working face tunnel. The front end of the detection pipeline has a tee 4300, one end is close to the goaf, and the other end is far away from the goaf;

At this time, the transmission gear 2500 of the transmission wheel mechanism and the driving gear 2104 on the motor 2100 and the linkage gear 2404 in the roller mechanism are in a separated state;

[0125] The detection tube 4100 at the end of the detection pipeline is connected to the chassis 2001 through the flange 4200 and the connecting bolt 4500 (when connecting, the bottom hole of the flange 4200 on the detection tube 4100 is connected to the connecting hole 2004 on the chassis 2001) to prevent the pipeline or the working unit from moving when the working unit pushes the guide tube 2406 into the detection pipeline and increasing the pushing resistance. After the connection is completed, the forward air duct interface 2101 on the motor 2100 is connected to the air supply pipeline in the lane through the air duct; at this time, the front end of the guide tube 2406 on the roller 2400 is manually passed through the inverted U-shaped guide buckle 2003, between the upper roller ring 2302 and the lower roller ring 2303, and the guide tube 2304 in turn and sent into the detection tube 4100 connected to the chassis 2001;

[0126] The proportional pneumatic pressing device 2301 is activated, the upper roller ring 2302 and the lower roller ring 2303 clamp the threading tube 2406, the motor 2100 is started to rotate forward, and the power is transmitted to the double rocker device 2300 through the reducer 2200. The upper roller ring 2302 and the lower roller ring 2303 of the double rocker device 2300 drive the threading tube 2406 to be transported by rotation (the pushing speed of the double rocker device 2300 is set to 1m / min-4m / min). At this time, the roller 2400 rotates forward with the transportation of the threading tube 2406, so as to realize the continuous transportation of the threading tube 2406 in the detection pipeline;

[0127] Step 4: Adjust the position of the motor 2100 and the roller 2400 so that the transmission gear 2500 of the transmission wheel mechanism is in meshing state with the driving gear 2104 on the motor 2100 and the linkage gear 2404 in the roller mechanism, and reconnect the threading tube 2406 to the roller 2400:

At the same time, the position of the roller support connecting beam 2407 of the roller mechanism is moved so that the linkage gear 2404 is meshed with the transmission gear 2500, and then the roller support connecting beam 2407 is fixed to the chassis 2001; at this time, the transmission gear 2500 of the transmission wheel mechanism is in a meshing state with the driving gear 2104 on the motor 2100 and the linkage gear 2404 in the roller mechanism;

[0129] Then, the end of the guide tube 2406 is taken out from the fixing hole 2405, and gradually withdrawn from the inverted U-shaped guide buckle 2003, between the upper roller ring 2302 and the lower roller ring 2303, and the guide tube 2304, and then the end of the guide tube 2406 is fixed to the fixing hole 2405 on the roller 2400 again, so that the guide tube 2406 loses the constraint of the guide tube 2304, the upper roller ring 2302, the lower roller ring 2303 and the inverted U-shaped guide buckle 2003, and the guide tube 2406 is wound around the roller 2400 during the winding process;

[0130] Step 5: Connect the binding section of the prepared pipe bundle 3000 to the front end of the guide tube 2406 in the detection pipeline through a glass tape 5000 or a wear-resistant and tough thin wire;

[0131] Step 6: Recover the threading tube 2406 and lay the pipeline bundle 3000 in the detection pipeline:

[0132] Connect the reversing air duct interface 2102 on the motor 2100 to the air supply pipeline in the lane through the air duct, then start the motor 2100 and reverse the motor 2100. At this time, the driving gear 2104, the transmission gear 2500 and the linkage gear 2404 drive the roller 2400 to reverse, and the threading tube 2406 is rolled up on the outer peripheral surface of the roller 2400. During the continuous rotation of the roller 2400, the threading tube 2406 will pull the pipe bundle 3000 into the detection pipeline until the laying of the pipe bundle 3000 in the detection pipeline is completed, and then the motor 2100 is turned off to stop the recovery of the threading tube 2406.

[0135] A portable negative pressure extractor is used to test the first bundle tube 3100, the second bundle tube 3400 and the third bundle tube 3700 again to see if they are permeable, so as to avoid bundle tube blockage and affect the subsequent gas component detection; at the same time, a multimeter is used to measure and record the initial resistance values ​​of the first temperature sensor 3300, the second temperature sensor 3600 and the third temperature sensor 3900;

[0136] Step 9: Transfer or recover the quick laying device of bundled pipe in coal mine goaf:

[0137] The connection between the working unit and the detection pipeline and the air supply pipeline is released, and the working unit is lifted and placed on the mobile unit for transfer or recovery. Then, as the coal mining face continues to advance, the gas entering each detection point in the goaf is detected every day, the resistance value is obtained through the temperature sensor, and the gas is collected through the bundle tube. The range of the three spontaneous combustion zones in the goaf is determined by calculating its temperature change and monitoring its gas composition.

After the ends of each group of pipe bundle monomers are aligned, they are tied together along the length direction of each group of pipe bundle monomers from the end to the front end with glass tape to form a pipe bundle; wherein, In each group of pipe harness monomers, a non-binding section with a length of L1 is provided from the front end of the bundle tube to the rear, that is, in the non-binding section, the bundle tube and the temperature measuring wire are not tied and fixed with glass tape; at the same time, a binding section with a length of L2 is provided at the end of each group of pipe harness monomers for binding with the lead-through pipe; the length difference between two adjacent groups of pipe harness monomers is L; Step 2: Downhole detection pipeline connection: In the underground coal mining working face tunnel, each detection pipe and each tee and flange in the detection pipeline are connected, and one end of the detection pipeline with a tee at the front end is close to the goaf, and the other end is far away from the goaf; Step 3: Lay the lead pipe in the test pipeline: The pipeline bundles and the quick laying device for the bundled pipes in the coal mine goaf prepared on the ground are lowered together into the tunnel of the coal mining working face, the working unit is transported to the end of the detection pipeline by the mobile unit, and then the working unit is taken off the mobile unit with the help of a handle and placed next to the detection pipeline; the output shaft of the motor is in an extended state and separated from the transmission gear in the transmission wheel mechanism, and at the same time, the position of the roller support connecting beam is moved away from the tool box to separate the linkage gear from the transmission gear, and then the roller support connecting beam is fixed to the chassis; at this time, the transmission gear of the transmission wheel mechanism is separated from the driving gear on the motor and the linkage gear in the roller mechanism; Connect the detection tube at the end of the detection pipeline to the connection hole on the chassis through the flange and the connecting bolts to prevent the pipeline or the working unit from moving when the working unit pushes the guide tube into the detection pipeline, thereby increasing the pushing resistance. After the connection is completed, connect the forward air duct interface on the motor to the air supply pipeline in the lane through the air duct; then manually pass the front end of the guide tube on the drum through the inverted U-shaped guide buckle, between the upper roller ring and the lower roller ring, and the guide tube in turn and send it into the detection tube connected to the chassis; The proportional pneumatic pressing device is activated, the upper roller ring and the lower roller ring clamp the threading tube, the motor is started to rotate forward, and the power is transmitted to the double rocker device through the reducer. The upper roller ring and the lower roller ring of the double rocker device drive the threading tube to be transported by rotation. At this time, the roller rotates forward with the transportation of the threading tube, realizing the continuous transportation of the threading tube in the detection pipeline; Step 4: After the threading tube is delivered to the right place, adjust the motor output shaft to the retracted state, so that the driving gear on the motor is meshed with the transmission gear of the transmission wheel mechanism. At the same time, move the position of the roller support connecting beam, so that the linkage gear in the roller mechanism is meshed with the transmission gear, and then fix the roller support connecting beam to the chassis; Then, the end of the guide tube is taken out from the fixing hole, and gradually withdrawn from the inverted U-shaped guide buckle, between the upper roller ring and the lower roller ring, and the guide tube. Then, the end of the guide tube is fixed in the fixing hole on the roller again, so that the guide tube loses the constraint of the guide tube, the upper roller ring, the lower roller ring and the inverted U-shaped guide buckle. Step 5: Connect the binding section of the prepared pipe bundle to the front end of the guide tube in the detection pipeline; Step 6: Recover the lead-in pipe and lay the pipe bundle in the test pipeline: Connect the reversing air duct interface on the motor to the air supply pipeline in the lane through the air duct, then start the motor and reverse it. At this time, the driving gear, transmission gear and linkage gear drive the drum to reverse, and the threading pipe is rolled up on the outer surface of the drum. During the continuous rotation of the drum, the threading pipe will pull the pipe bundle into the detection pipeline until the laying of the pipe bundle in the detection pipeline is completed. Then, the motor is turned off and the recovery of the threading pipe is stopped. Step 7: After the threading pipe is recovered, each bundle tube and temperature measuring wire in the pipeline bundle are found one by one through each tee, and then the flower tube is installed on each tee, and each bundle tube and each temperature sensor is fixed in each flower tube; Step 8: Check whether each bundle tube is transparent and check the initial resistance of each temperature sensor; Step 9. Transfer or recover the quick laying device for bundled pipes in the goaf of coal mines: release the connection between the working unit and the detection pipeline and the air supply pipeline, lift the working unit onto the mobile unit, and then transfer or recover it.
