Description

Technical Field

[0001] This invention belongs to the technical field of underground auxiliary transportation equipment in coal mines, specifically a coal mine production material collection, transportation and distribution equipment and operation method. Background Technology

[0002] With the intensifying contradiction between coal energy supply and demand and the advancement of mining technology, the mining intensity of low-mining, high-facing longwall faces has increased, and vertical shaft coal mines are developing in greater depth. The process of trackless auxiliary transportation is rapidly advancing, but the conditions for using trackless auxiliary transportation vehicles are becoming increasingly limited, and containerized transportation in confined spaces is becoming more difficult to implement. In fully mechanized longwall faces, the passageway on one side of the belt conveyor roadway is relatively narrow, limiting trackless transport vehicles to locations far from the working face. In low-lying coal seams, ordinary trackless vehicles are unusable. Conventional materials such as pipes, grease, and equipment mainly rely on manual handling. As the working face shortens, materials also need to be manually transferred to different locations. In some inclined shaft coal mines with steep slopes, materials are currently transported down the mine using rail-traction mine cars, and then transferred to trackless vehicles for further transport to the unloading point. Material transfer relies on manual labor or the use of underground cranes, resulting in low efficiency. In some vertical shaft coal mines using cage hoisting, shorter vehicles can be directly loaded into the cage, while longer vehicles must be disassembled. The car body and material box are lowered into the cage and then reassembled, resulting in a large workload and low efficiency. Therefore, a container loading and unloading equipment that can efficiently transfer and quickly connect containers in confined spaces should be configured to enable container self-loading and unloading operations in low and narrow alley conditions.

[0003] Trackless auxiliary transportation involves dispersed work locations, numerous links and branches in the transportation routes, and frequent changes required as the working face extends, shortens, or relocates. The transported materials are diverse in type and shape. These characteristics necessitate a variety of auxiliary transportation equipment types, resulting in flatbed trucks, dump trucks, and other vehicle models. Above-ground loading is scattered, while underground unloading and stacking rely primarily on manual labor supplemented by simple machinery such as hand hoists, jacks, and crowbars. This traditional, fragmented auxiliary transportation model requires a large number of personnel and vehicles, is labor-intensive, and suffers from low vehicle turnover and transport efficiency. Furthermore, the materials are piled up at unloading points, making retrieval inconvenient and posing challenges to material management. Therefore, to achieve reduced manpower and increased efficiency in trackless auxiliary transportation, this invention proposes a method for the collection, transportation, and distribution of coal mine production materials. Summary of the Invention

[0004] This invention addresses the current situation of trackless transportation in coal mines. To solve the problems of inconvenient unloading and cumbersome material transfer in adits, inclined shafts, and vertical shafts, it provides a coal mine production material collection and distribution equipment and operation method. It adopts efficient transferable collection and distribution equipment and material containers to carry out centralized material distribution, long-distance transportation, rapid loading and unloading, and full-process material tracking and control. It can reduce the number of operators, reduce labor intensity, improve vehicle turnover rate and transportation efficiency, and realize the intensification of underground auxiliary transportation personnel and equipment and the scientification of material distribution.

[0005] The technical solution adopted in this invention is to provide a coal mine production material collection and distribution equipment, including a container transport vehicle and a container. The container transport vehicle is equipped with a container loading rack for loading the container. The container loading rack has a U-shaped opening structure and is equipped with a container changing mechanism. The container changing mechanism includes a quick-change mechanism and a locking mechanism. The quick-change mechanism is used to lift the container to load it onto the container loading rack and to unload and lower the container from the container loading rack. The locking mechanism is used to restrict and fix the container after it is loaded onto the container loading rack. A container side-moving mechanism is provided on the container for self-movement of the container.

[0006] Furthermore, the container side-shifting mechanism includes a translation mechanism and a lifting mechanism. The translation mechanism includes a base disposed below the container and a third drive unit for moving the container relative to the base. The lifting mechanism includes a support seat disposed on the container for supporting the ground and a fourth drive unit for driving the support seat to extend and retract.

[0007] Furthermore, a guiding mechanism is provided between the base and the container. The guiding mechanism includes a sliding guide sleeve and a guide shaft that are connected in a sleeve. One of the base and the container is fixedly connected to the sliding guide sleeve, and the other is connected to the guide shaft.

[0008] Furthermore, the third drive unit is a push cylinder, and the fourth drive unit is a support leg cylinder. The drive oil for the push cylinder and the support leg cylinder is taken from the container truck.

[0009] Furthermore, the quick-change mechanism is located on both inner sides of the U-shaped opening of the container loading rack. The quick-change mechanism includes a support member pivotally connected to the container loading rack. The support member is connected to the first drive unit to control the pivoting swing of the support member. The end of the support member away from the pivot point is the support part. The container is placed in the U-shaped opening of the container loading rack. The container has locking parts on both sides. The support part acts on the locking parts to swing upward to load the container onto the container loading rack, and swings downward to unload the container from the container loading rack.

[0010] Furthermore, the container transport vehicle includes a front frame for towing container loading racks. The front frame is connected to the drive axle via an adjustable suspension. The suspension includes a swing arm and a tie rod. The front part of the swing arm is fixed to the drive axle, and the rear part is hinged to the front frame. The tie rod is vertically arranged, with one end hinged to the swing arm and the other end hinged to the front frame. Suspension cylinders are symmetrically arranged on both sides of the front frame. The piston rod end of the suspension cylinder is hinged to the swing arm, and the cylinder end is hinged to the front frame.

[0011] Furthermore, the system includes a control system comprising a controller, distance sensors, an electro-hydraulic regulating valve, and a solenoid directional valve. The distance sensors are installed at the highest and lowest points of the front frame to monitor the clearance between the highest point of the equipment and the roadway roof, and the clearance between the lowest point of the equipment and the roadway floor. The outlet of the electro-hydraulic regulating valve is connected to the oil ports of the rod-side and rodless-side chambers of the suspension cylinder to control the flow of hydraulic fluid. The outlet of the solenoid directional valve is connected to the inlet of the electro-hydraulic regulating valve to switch the hydraulic fluid flow between the rod-side and rodless-side chambers of the suspension cylinder. The controller receives the monitoring data from the distance sensors and controls the electro-hydraulic regulating valve and the solenoid directional valve based on the monitoring data to adjust the extension and retraction of the suspension cylinder.

[0012] Furthermore, the method for the controller to control the suspension cylinder includes the following steps: S1. Compare the top clearance data with the set value. If it is lower than or equal to the minimum set value, control the suspension cylinder to lower the front frame. During the descent, compare the ground clearance data with the set value again. If it is lower than or equal to the minimum set value, the vehicle body descent will stop. S2. If the top clearance data exceeds the maximum set value, control the suspension cylinder to raise the front frame. During the raising process, compare the ground clearance data with the set value. If it exceeds the maximum set value, the vehicle body will stop rising.

[0013] The coal mine production material collection and distribution equipment provided by this invention has the following beneficial effects: 1. It enables efficient container transshipment within the confined space of underground coal mines, realizing containerized transportation and mechanized loading and unloading of coal production materials; it also enables rapid connection and convenient transfer of inclined shaft rail traction transportation and vertical shaft cage transportation, improving material transportation efficiency while reducing the intensity of manual transshipment operations and saving the number of underground workers.

[0014] 2. The container can be moved to the side of the tunnel underground without occupying the tunnel's passage width. It uses a quick-connect coupling to take power from the vehicle body and does not require other underground power sources.

[0015] 3. The electro-hydraulic coordinated control system enables active height adjustment of the collection and distribution equipment, which can improve the adaptability of the roadway.

[0016] This invention also provides a method for the collection, transportation, and distribution of coal mine production materials, employing the aforementioned collection, transportation, and distribution equipment, and comprising the following steps: S1. Material Outbound: Based on the material requirements for production, the Inoue Warehouse Center prepares materials, and the transportation team collects the materials. S2, In-ground loading: The transport team uses containers to consolidate materials into integrated units; S3. Downhole Transportation: Depending on the application location of the materials and the tunnel development method, container trucks are called to load containers and drive them directly to the mine, or they are transferred to rail flatbed cars and pulled down the mine by steel wire ropes, or they are transferred to cages and sent down the mine by cages, and then the containers are loaded and transported by container trucks in the mine. S4. Underground unloading: After the container truck arrives at the unloading point, it unloads the container and moves it to the side of the tunnel. S5. Material Usage: Containers serve as temporary warehouses, and materials can be retrieved as needed.

[0017] Furthermore, a material control system is used for management. In S1, material code information is obtained when the goods leave the warehouse; in S2, the material is bound to the container information; in S3, the container is bound to the vehicle information and the material is tracked; in S4, the transportation team and the production team hand over the materials and the container and vehicle information are unbound; in S5, the material consumption is statistically analyzed and feedback is provided, and the supply and demand balance is analyzed through the container material control system.

[0018] The present invention provides a method for the collection, transportation, and distribution of coal mine production materials, which has the following beneficial effects: 1. By adopting efficient interchangeable collection and distribution equipment and material containers, centralized material distribution, long-distance transportation, rapid loading and unloading, and full-process material tracking and control can be achieved. This enables rapid connection and convenient transfer between inclined shaft rail traction transportation and vertical shaft cage transportation, improving material transportation efficiency while reducing the intensity of manual transfer operations and saving the number of underground workers.

[0019] 2. Track and control the entire process of container material outbound, loading, transportation, unloading and use, and establish a coal mine production material collection and distribution model with self-optimization of transportation and self-balancing of material use, which will significantly improve transportation efficiency and achieve lean material management.

[0020] 3. It solves the problems of inconvenient unloading and cumbersome material transfer in adits, inclined shafts and vertical shafts, improves vehicle turnover and transportation efficiency, and realizes the intensification of underground auxiliary transportation personnel and equipment and the scientification of material distribution.

Detailed Implementation

[0034] To better understand the purpose, structure, and function of this invention, the following detailed description, in conjunction with the accompanying drawings, provides an equipment and method for collecting, transporting, and distributing coal production materials according to this invention.

[0035] like Figures 1-5 As shown, a coal mine production material collection and distribution equipment includes a container transport vehicle and a container 5. The container transport vehicle is equipped with a container loading rack 2 for loading the container 5. The container loading rack 2 has a U-shaped opening structure and is equipped with a container transfer mechanism 3. The container transfer mechanism 3 includes a quick-change mechanism 3-1 and a locking mechanism 3-2. The quick-change mechanism 3-1 is used to lift the container 5 to load it onto the container loading rack 2 and to unload and lower the container 5 from the container loading rack 2. The locking mechanism 3-2 is used to restrict and fix the container 5 when it is loaded onto the container loading rack 2. A container side-moving mechanism 4 is provided on the container 5 for self-movement of the container 5.

[0036] The container loading rack 2 of this invention has a U-shaped opening structure, and the container 5 is independent of the container loading rack 2. When the two are assembled, the container 5 is located within the U-shaped frame of the container loading rack 2 and is connected to the container loading rack 2 through the container transfer mechanism 3. This invention can efficiently transfer the container 5 in the confined space of underground coal mines, realizing the containerized transportation of coal production materials and mechanized loading and unloading operations.

[0037] like Figure 2 and Figure 5 As shown, in this embodiment, the quick-change mechanism 3-1 consists of two sets of parallelogram-shaped linkage mechanisms symmetrically arranged on both sides of the U-shaped opening of the container loading rack 2. Each set of parallelogram-shaped linkage mechanisms includes a first support member 3-1-1, a connecting rod 3-1-2, and a second support member 3-1-3. The first support member 3-1-1 is connected to the first drive unit. The two ends of the connecting rod 3-1-2 are hinged to one end of the first support member 3-1-1 and one end of the second support member 3-1-3, respectively. The other ends of the first support member 3-1-1 and the second support member 3-1-3 are hinged to the container loading rack 2. It can be understood that the linkage mechanism connected to the first drive unit is not necessarily the first support member 3-1-1; it could also be the connecting rod 3-1-2 or the second support member 3-1-3, depending on the lifting force and equipment layout. In addition, in this embodiment, the first drive unit adopts quick-change cylinders 8-7, which are symmetrically arranged inside the main beams on both sides of the container loading frame 2. The piston rod end of the quick-change cylinder 8-7 is connected to the first support member 3-1-1, and the cylinder end is hinged to the container loading frame 2.

[0038] like Figure 5 and Figure 6As shown, the locking mechanism 3-2 includes a pin fixing frame 3-2-1 and two pins 3-2-2. The pin fixing frame 3-2-1 is fixed to the second drive unit, which controls the extension and retraction of the pin fixing frame 3-2-1. The two pins 3-2-2 are symmetrically located on both sides of the pin fixing frame 3-2-1 and are fixed to the pin fixing frame 3-2-1 by bolts. In this embodiment, the second drive unit adopts a locking cylinder 8-8, which is located inside the front beam of the container loading frame 2. The piston rod end of the locking cylinder 8-8 is hinged to the container loading frame 2, and the cylinder end is connected to the pin fixing frame 3-2-1.

[0039] like Figure 3 and Figure 4 As shown, container 5 includes a front pallet 5-1, two middle side pallets 5-2, two rear side pallets 5-3, and a container body 5-6. The front pallet 5-1 and rear side pallets 5-3 are at the same horizontal level as the container body 5-6. The front pallet 5-1 is welded to the front side of the container body 5-6. A hole is provided on the front pallet 5-1 corresponding to the position of pin 3-2-2. The maximum diameter of pin 3-2-2 is slightly smaller than the diameter of the hole in the front pallet 5-1. The end of pin 3-2-2 has a conical design to facilitate insertion into the corresponding hole in the front pallet 5-1. The two middle side pallets 5-2 and the two rear side pallets 5-3 are symmetrically welded to both sides of the container body 5-6.

[0040] The container side-moving mechanism 4 enables the container 5 to move independently, allowing it to move laterally to the side of the tunnel underground without obstructing the tunnel's passage width. In this embodiment, the container side-moving mechanism 4 includes a translation mechanism 4-1 and a lifting mechanism. The translation mechanism 4-1 includes a base 4-1-1 positioned below the container 5 and a third drive unit that moves the container 5 relative to the base 4-1-1. The lifting mechanism includes a support seat 4-2 positioned on the container 5 to support the ground and a fourth drive unit that extends and retracts the support seat 4-2.

[0041] The translation mechanism 4-1 consists of an L-shaped base 4-1-1, two first lugs 4-1-2, and two guide shafts 4-1-3. The third drive unit is a push cylinder 8-10. There are two push cylinders 8-10, which are arranged in parallel between the container 5 and the base 4-1-1. The holes of the two first lugs 4-1-2 are coaxial, and they are welded one in front of the other between the vertical plate and the horizontal plate of the base 4-1-1. The first lugs 4-1-2 are hinged to the piston rod end of the push cylinder 8-10, and the cylinder barrel end of the push cylinder 8-10 is hinged to the container 5. The two guide shafts 4-1-3 are parallel and are welded one in front of the other to the vertical plate of the base 4-1-1.

[0042] Two push guide sleeves 5-4 and two second lugs 5-5 are provided at the bottom of the container body 5-6. The second lugs 5-5 are hinged to the cylinder end of the push cylinder 8-10. The two parallel push guide sleeves 5-4 are welded to the bottom of the container body 5-6 one in front of the other. When the container side-shifting mechanism 4 is assembled with the container 5, two guide shafts 4-1-3 are inserted into the two push guide sleeves 5-4, and the two are coaxial. The guide shafts 4-1-3 cooperate with the push guide sleeves 5-4 to provide guidance and connection. Their cross-sectional shape is not limited. In addition to being circular, they can also be triangular, rectangular, dovetail-shaped, etc.

[0043] The lifting mechanism includes two support seats 4-2 located at the front and rear of the container body 5-6. The fourth drive unit is outrigger cylinders 8-9. There are four outrigger cylinders 8-9, two of which are symmetrically arranged at the front of the container 5, with the cylinder ends fixed to the container 5 and the piston rod ends hinged to one support seat 4-2 of the container side-shifting mechanism 4. The other two are symmetrically arranged at the rear of the container 5, with the cylinder ends fixed to the container 5 and the piston rod ends hinged to the other support seat 4-2 of the container side-shifting mechanism 4. The four outrigger cylinders 8-9 are located on the same horizontal line. The driving hydraulic fluid for the pushing cylinder 8-10 and the outrigger cylinders 8-9 is taken from the container transport vehicle, which is not limited by the operating environment conditions and does not require the assistance of other mechanical equipment to move the container 5 to the designated position.

[0044] like Figure 2 and Figure 5 As shown, the container transport vehicle includes a front frame 1 that tows the container loading rack 2. The front frame 1 is hinged to the container loading rack 2. The front frame 1 is connected to the drive axle via an adjustable suspension 6. The suspension 6 includes a swing arm 6-1, a tie rod 6-2, and suspension cylinders 8-13. The front part of the swing arm 6-1 is fixed to the drive axle, and the rear part is hinged to the front frame 1. The tie rod 6-2 is vertically arranged, with one end hinged to the swing arm 6-1 and the other end hinged to the front frame 1. Suspension cylinders 8-13 are symmetrically arranged on both sides of the front frame. The piston rod end of the suspension cylinder 8-13 is hinged to the swing arm 6-1, and the cylinder end is hinged to the front frame 1. The swing arm 6-1 can be hinged to the front frame 1 as a single point (A-shape) or as two points (left and right). The suspension 6 enables active height adjustment of the transport and distribution equipment, improving its adaptability to roadways.

[0045] The control system 8 is located on the front frame 1 and is used to control the container transshipment mechanism 3, the container side-shifting mechanism 4, and the suspension 6. For example... Figure 7As shown, the control system 8 includes a hydraulic pump 8-1, a hydraulic oil tank 8-2, a safety valve 8-3, a multi-way valve 8-4, a two-way balance valve 8-5, a one-way balance valve 8-6, a quick-change cylinder 8-7, a locking cylinder 8-8, an outrigger cylinder 8-9, a push cylinder 8-10, a quick connector 8-11, a distributor valve 8-12, a suspension cylinder 8-13, an accumulator 8-14, a distance sensor 8-15, a controller 8-16, an electro-hydraulic regulating valve 8-17, and a solenoid directional valve 8-18.

[0046] The hydraulic pump 8-1, hydraulic oil tank 8-2, safety valve 8-3, multi-way valve 8-4, two-way balance valve 8-5, one-way balance valve 8-6, accumulator 8-14, controller 8-16, electro-hydraulic regulating valve 8-17, and solenoid directional valve 8-18 are installed on the front frame 1. There are four quick-connect plugs 8-11, two of which connect to the multi-way valve 8-4, and the other two connect to the hydraulic oil tank 8-2. The distributor valve 8-12 is installed in container 5.

[0047] Distance sensors 8-15 are installed at the highest and lowest points of the front frame 1, respectively, to measure the distance between the highest point of the equipment and the roof of the roadway, and the distance between the lowest point and the floor of the roadway. The number of distance sensors 8-15 is not limited to two; multiple distance sensors 8-15 can be arranged on the upper and lower parts of the equipment to measure the gap. The controller 8-16 calculates the average value of the multiple measurements and then compares it with the set value.

[0048] Control system 8 can realize the functions of container 5 loading and unloading, container 5 side movement, and vehicle height adaptive adjustment. The specific implementation process is as follows: 1. Container transshipment process: When container 5 needs to be loaded, load it first. Operate the first working link of the multi-way valve 8-4 to allow high-pressure oil to enter the rodless chamber of the quick-change cylinder 8-7 through the two-way balance valve 8-5, causing the piston rod to extend. This causes the first support member 3-1-1 and the second support member 3-1-3 to rotate backward around the container loading frame 2, and the connecting rod 3-1-2 to perform a translational movement, lowering the container quick-change mechanism 3 to its lowest position. Adjust the vehicle position so that the vehicle and container 5 are basically aligned longitudinally. Drive the vehicle until the limiting plate of the first support member 3-1-1 contacts the front end of the two middle side support plates 5-2 of the container 5. Manipulate the first working link of the multi-way valve 8-4 to allow high-pressure oil to enter the rod chamber of the quick-change cylinder 8-7 through the bidirectional balance valve 8-5, causing the piston rod to retract. The first support member 3-1-1 and the second support member 3-1-3 rotate forward around the container loading frame 2, and the connecting rod 3-1-3 makes a translational movement, lifting the container 5 so that the front pallet 5-1 and the two rear side pallets 5-3 fall onto the container loading frame 2. The locking hook of the second support member 3-1-3 hooks the middle side pallet 5-2 of the container 5.

[0049] After locking, operate the second working link of the multi-way valve 8-4 to allow high-pressure oil to enter the rodless chamber of the locking cylinder 8-7 through the one-way balance valve 8-6. The cylinder extends and drives the pin fixing bracket 3-2-1 and the two pins 3-2-2 to move upward until the two pins 3-2-2 are inserted into the corresponding holes of the front support plate 5-1 of the container 5, thus completing the container loading process.

[0050] The container unloading process is the reverse of the loading process; that is, the container is unlocked first, and then unloaded. The specific process will not be described in detail here.

[0051] 2. Container Side-Shifting Process: Connect the four quick-connect plugs 8-11 to the corresponding working ports and return ports of the distributor valve 8-12. Operate the third working link of the multi-way valve 8-4, allowing high-pressure oil to enter the rodless chamber of the outrigger cylinder 8-9 through the one-way valve of the first bidirectional balance valve of the distributor valve 8-12. This causes the piston rod to extend, and the piston rod drives the two support seats 4-2 of the lifting mechanism to move down to contact the ground, simultaneously lifting the container 5. The translation mechanism 4-1 of the container side-shifting mechanism 4 is also lifted along with the container 5. Operate the fourth working link of the multi-way valve 8-4, allowing high-pressure oil to enter the rodless chamber of the push cylinder 8-10 through the one-way valve of the second bidirectional balance valve of the distributor valve 8-12. This causes the piston rod to extend, and the piston rod drives the base 4-1-1 of the translation mechanism 4-1 to move to one side until the base 4-1-1 has moved one stroke of the push cylinder 8-10 or a specified stroke.

[0052] Operating the third working link of the multi-way valve 8-4 allows high-pressure oil to enter the rod chamber of the outrigger cylinder 8-9 via the check valve of the first bidirectional balance valve of the distributor valve 8-12. This retracts the cylinder, causing it to move container 5 downwards until it contacts the ground. Container 5 then moves the translation mechanism 4-1 of the container side-shifting mechanism 4 to the ground. Operating the fourth working link of the multi-way valve 8-4 allows high-pressure oil to enter the rod chamber of the push cylinder 8-10 via the check valve of the second bidirectional balance valve of the distributor valve 8-12. This retracts the cylinder, causing it to move container 5 horizontally, positioning it in its initial assembly position with the translation mechanism 4-1. This completes one step of movement. The operation can be repeated as needed until container 5 is positioned close to the side of the aisle.

[0053] After the container is moved to the side, disconnect the quick plug 8-11 from the liquid distribution valve 8-12.

[0054] 3. Vehicle height adaptive adjustment process: Please refer to... Figure 8The distance sensor 8-15 on the upper part of the front frame 1 measures the equipment's overhead clearance in real time, and the distance sensor 8-15 on the lower part of the front frame 1 measures the equipment's ground clearance in real time. The controller 8-16 first compares the overhead clearance data with the set value. If it is lower than or equal to the minimum set value, the vehicle body needs to descend. The controller 8-16 outputs a descent command, controlling the four electro-hydraulic regulating valves 8-17 and the two solenoid directional valves 8-18 to switch directions. The solenoid directional valves 8-18 are in the right position, and high-pressure oil enters the rod chamber of the two suspension cylinders 8-13. The cylinders contract, and the oil in the rodless chamber returns, and the vehicle body begins to descend. During the descent, the controller 8-16 again compares the ground clearance data with the set value. If it is lower than or equal to the minimum set value, the descent of the vehicle body must stop. The controller 8-16 outputs a stop descent command, controlling the electro-hydraulic regulating valve 8-17 to return to its original position, cutting off the high-pressure oil entering and exiting the suspension cylinders 8-13, thereby stopping the descent.

[0055] If the ground clearance data exceeds the maximum set value, the vehicle body can rise. Controller 8-16 outputs a rise command, controlling the four electro-hydraulic regulating valves 8-17 and two solenoid directional valves 8-18 to switch positions. Solenoid directional valves 8-18 are in the left position, allowing high-pressure oil to enter the rodless chambers of the two suspension cylinders 8-13. The cylinders extend, and the oil in the rod chambers returns, initiating the rise of the vehicle body. During the rise, controller 8-16 compares the ground clearance data with the set value. If it exceeds the maximum set value, the rise must stop. Controller 8-16 outputs a stop rise command, controlling the electro-hydraulic regulating valve 8-17 to return to its original position, cutting off the high-pressure oil supply to and from the suspension cylinders 8-13, thus stopping the rise.

[0056] Lower the vehicle body in low-ceilinged aisles to reduce the loading and unloading height of container 5, and raise the vehicle body in higher aisles to improve the driver's visibility.

[0057] like Figure 9 As shown, the present invention provides a method for the collection, transportation, and distribution of coal mine production materials, employing the aforementioned collection, transportation, and distribution equipment. The operational flow is as follows: S1. Material Outbound: Based on production material requirements, the Inoue Warehouse Center prepares materials, and the transportation team collects them. A container material control system is used to obtain material code information upon outbound processing. S2, Loading at the Well: The transport team uses container 5 to consolidate materials into integrated units. The information of the materials is then linked to that of container 5. S3. Downhole Transportation: Depending on the material application location and tunnel development method, the downhole transportation process should at least include the following: Figures 10-12 The three schemes shown in the diagram are illustrated. The dashed arrows indicate the direction of movement for consolidation, distribution, and assembly, and the dashed arrows also indicate the direction of movement for the containers. like Figure 10The first solution shown is to use the coal mine production material collection and distribution equipment of the present invention to load container 5 and drive it directly underground; like Figure 11 The second option shown is as follows: Container 5 is transferred to a rail flatcar via a collection and distribution equipment, and the rail flatcar is pulled down into the well by a steel wire rope. Then, the collection and distribution equipment in the well loads Container 5. like Figure 12 The third option shown is: Container 5 is transferred to the cage by the collection and distribution equipment, sent down the well by the cage, and then loaded into the container by the collection and distribution equipment in the well. During the above transportation process, container 5 will be linked to vehicle information to track the materials; S4. Underground unloading: After the collection and distribution equipment arrives at the unloading point, it unloads container 5 and moves container 5 to the side of the roadway. The transportation team and the production team hand over the container 5 and complete the unbinding of the information between the container and the vehicle. S5. Material Usage: Container 5 becomes a temporary warehouse, and materials are retrieved as needed. If the length of the working face changes, the collection and distribution equipment is called to move Container 5. During use, the material consumption is statistically analyzed and feedback is provided, and the supply and demand balance is analyzed through the container material management system.

[0058] Through the above process, using special containers equipped with material information for transportation, it is possible to complete the containerized distribution of materials and mechanized loading and unloading operations, while also achieving closed-loop information management of the entire material flow process.
