Technical Field
[0001] This invention relates to the field of coal mine roadway support, and in particular to an integrated robot for automatic anchoring of the entire cross-section of coal mine roadways, which aims to improve the automation and intelligence of anchoring operations, reduce the labor intensity of workers, and improve work efficiency and safety. Background Technology
[0002] In the process of anchoring in coal mine roadways, traditional manual operation has many problems such as high labor intensity, low efficiency, and poor safety. With the development of coal mining towards intelligentization, traditional manual anchoring operations can no longer meet the high efficiency and safety requirements of modern coal mine production. Therefore, it is of great significance to develop an integrated robot for full-section automatic anchoring in coal mine roadways. Summary of the Invention
[0003] This invention addresses the problems of low anchoring efficiency and roof rock collapse and spalling in existing coal mine roadways by proposing an integrated robot for full-section automatic anchoring of coal mine roadways.
[0004] The technical solution is as follows: The robot of this invention mainly comprises the following modules: walking module, power source and control module, laser radar positioning module, net storage module, net retrieval module, net transportation module, net laying module, and anchoring module.
[0005] The aforementioned walking module includes drive wheels, tracks, track rollers, trolley frame, support rollers, tensioning device, guide wheels, chassis platform, and hydraulic motor; different bandwidths can be selected and replaced according to the ground pressure of different terrains to adapt to complex coal mine roadway terrain, and its power comes from the aforementioned hydraulic pump station.
[0006] The power source and control module includes an integrated electrical control cabinet, a hydraulic pump station, guardrails, pressure control valves, a cooling fan, an oil tank, a main pump, and an auxiliary pump. The main pump and auxiliary pump draw hydraulic oil from the oil tank and supply it to the traveling module, net storage module, net retrieval module, net laying module, and anchoring module, as well as draw back hydraulic oil. The pressure control valve controls the flow of hydraulic oil through different valves. The guardrails protect the power source and control module from being scraped by the tunnel wall.
[0007] The lidar positioning module includes a data processing center, a laser transmitter, a signal feedback sensor, a lidar frame, and a lidar mounting base; the lidar positioning module is responsible for three-dimensional modeling and real-time positioning of the tunnel, providing high-precision navigation and work area identification.
[0008] The aforementioned net storage module adopts a scissor-type hydraulic lifting net storage box design, including an anchor net box, a lifting platform support, a gravity sensor, and a scissor-type lifting hydraulic cylinder. It serves to store anchor nets and automatically adjust the height of the anchor net box according to the decrease in the number of anchor nets in the box.
[0009] The net-retrieval module includes a horizontal moving screw, a vertical moving screw, a gantry column, an anchor net retrieval robot, a fixing sleeve for the retrieval robot, a gravity interconnection sensor, a crossbeam, and a connecting beam. The horizontal and vertical moving screws are used to adjust the position of the anchor net retrieval robot. The anchor net retrieval robot is used to grab the anchor net from the anchor net box in the net storage module. The gravity interconnection sensor is used to receive the gravity sensor signal to prepare for net retrieval. The gantry column, crossbeam, and connecting beam are used to fix the horizontal and vertical moving screws and protect the net storage module, thereby achieving precise grabbing and transportation of the anchor net.
[0010] The net conveying module adopts a double-layer anchor net conveyor structure, mainly including a drive motor, an anchor net electromagnetic fixing plate assembly, a pressure sensor, a net conveying module base, and upper and lower conveyors. The anchor net electromagnetic fixing plate assembly fixes both ends of the anchor net through an electromagnetic field, and the anchor net is transported to the net laying module by the drive motor and the conveyor. The pressure sensor is responsible for sensing the pressure brought by the anchor net. When the pressure drops, it transmits the signal to the gravity sensor and gravity interconnection sensor, thereby realizing the continuous supply of anchor net.
[0011] The net laying module includes an anchor net laying robot and a net laying module base. The anchor net laying robot includes two side net laying robots and a central roof net laying robot. The net laying module automatically lays nets across the entire cross-section of the coal mine roadway by grabbing the anchor nets in the net transport module.
[0012] The anchoring module includes a top plate anchoring module, a top plate anchoring module fixing seat, a side wall anchoring module, gantry columns, and crossbeams; the anchoring module starts up simultaneously with the mesh laying module, realizing simultaneous anchoring and mesh laying operations.
[0013] The aforementioned fully automated integrated anchoring robot for coal mine roadways addresses the problems of high labor intensity, low efficiency, and poor safety in full-section anchoring operations in coal mine roadways. It proposes a highly automated and safe fully automated integrated anchoring robot. The robot's structure includes multiple modules, which coordinate to achieve an automated anchoring operation process. The basic working process of this invention is as follows: The robot is started via a remote control center, activating the walking module, which drives the hydraulic motor-driven tracked chassis to move the robot forward and enter the coal mine roadway. This process is achieved by the aforementioned power source and control module; the robot... After the robot enters the tunnel, the laser radar positioning module is activated. This module uses the laser emitter and the signal feedback sensor to perform a three-dimensional scan of the tunnel, generating a three-dimensional image of the tunnel. This enables precise anchoring and navigation control, ensuring the robot can accurately reach the work area. When the robot reaches the anchoring work area, the net transport module is activated. The net transport module consists of a double-layer anchor net transport machine and a synchronous belt drive mechanism. Through a chain drive mechanism, the anchor nets in the storage and retrieval modules are transported to the net laying module. The anchor nets pre-installed on the net transport module are delivered to their designated positions after positioning. This prepares for subsequent netting operations. After the netting module is activated, the anchor netting laying robot begins work. This module consists of two sidewall netting laying robots and one roof netting laying robot. The anchor netting laying robot grabs the anchor netting from the netting transport module and lays it on the roof and sidewall areas of the roadway. Simultaneously, the anchoring module is activated. This module includes two sidewall anchoring modules and one roof anchoring module. This module uses a bolt drilling rig to reinforce the roof, sidewalls, and anchor netting, ensuring that the bolts fix the roadway and the anchor netting are firmly fixed to the roadway surface, enhancing the stability and safety of the roadway support. When the net transport module detects a decrease in the number of anchor nets, it automatically activates the net retrieval module. The net retrieval module uses the anchor net retrieval robot to extract new anchor nets from the net storage box and transport them to the anchor net electromagnetic fixing plate group of the net transport module. After the anchor net is fixed on the anchor net electromagnetic fixing plate group of the net transport module, the net transport module is activated again to transport the anchor net to the net laying module. At the same time, the scissor-type hydraulic lifting net storage box in the net storage module automatically adjusts its height according to the decrease in the weight of the anchor net, ensuring the smooth progress of the net retrieval process. This process is repeated repeatedly to ensure continuous anchoring operations in the roadway.
[0014] The advantages of this invention are:
[0015] 1. The net-laying module of the robot of this invention adopts a multi-degree-of-freedom manipulator collaborative net-laying structure design. The anchoring module adopts a structure layout of one top anchor and two side anchors, covering the area at the junction of the roof and sidewalls to ensure the full-section net-laying effect. The anchoring module anchors the roof and sidewalls through an anchor drilling machine and monitors the drilling depth in real time to ensure the roadway support strength.
[0016] 2. The robot of this invention adopts an automated net supply and grasping system. The net storage module and net retrieval module monitor the remaining amount of anchor net in real time through gravity sensors and gravity interconnection sensors, and automatically adjust the storage height and supply status of anchor net to ensure a stable supply of anchor net. At the same time, the grasping manipulator equipped with the net retrieval module can accurately locate and grasp the anchor net and place it in the net transport module, reducing errors and improving the accuracy of operation.
[0017] 3. The robot of this invention adopts a double-layer net transport structure. The net transport module uses a double-layer conveyor to ensure the stability of the anchor net during transportation and reduce the risk of slippage or falling. The upper and lower sets of anchor net electromagnetic fixing plates can firmly fix the anchor net during transportation. The pressure sensor of the net transport module can monitor the remaining quantity of anchor net in real time and transmit the signal to the net transport module and the net retrieval module to ensure that there is enough anchor net to supply, so that the net laying module and the anchoring module can work continuously.
[0018] 4. The robot of this invention adopts a precise lidar positioning system. Through the lidar positioning module, the robot can perform real-time three-dimensional scanning of the tunnel environment and generate a high-precision three-dimensional model, providing accurate data support for the collaboration of various modules. Compared with traditional manual positioning, this system ensures the accuracy of the anchor position, avoids repetition or omission, and improves the intelligence and safety of tunnel support operations.
[0019] 5. The walking module of the robot of this invention adopts a four-track design. This structure can not only evenly distribute the weight of the equipment and reduce damage to the tunnel surface, but also cross complex terrain. This structure can also travel for a long time on soft ground and in long tunnels, and is suitable for various types of tunnels. Attached Figure Description

The control module 2 is bolted to the rear of the walking module 1; the net storage module 4 is bolted to the walking module 1 and located at the front of the power source and control module 2; the net retrieval module 5 is bolted to the walking module 1 and surrounds the net storage module 4; the net transport module 6 is bolted to the walking module 1 and located at the front of the net retrieval module 5; the net laying module 7 is bolted to the walking module 1 and located at the front of the net transport module 6; the anchoring module 8 is bolted to the walking module 1 and located at the front of the net laying module 7, to achieve efficient anchoring. Figure 1 and Figure 2 The image shows the details of the robot's full-section anchoring process. Figure 3 The diagram shows the overall structure of the robot.
[0044] Reference Figure 4 and Figure 5The walking module 1 includes a drive wheel 10, tracks 11, track rollers 12, a trolley frame 13, support rollers 14, a tensioning device 15, guide wheels 16, a chassis platform 17, and a hydraulic motor 18. The drive wheel 10, tracks 11, track rollers 12, support rollers 14, tensioning device 15, guide wheels 16, and hydraulic motor 18 in the walking module 1 are all mounted on the trolley frame 13. In this invention, the walking module 1 adopts a four-track design. Compared with the traditional double-track or wheeled structure, this structure has better stability. The four tracks can distribute the weight of the equipment more evenly, especially in complex terrain or poor geological conditions in coal mine roadways, effectively reducing the risk of overturning. Coal mine roadways are often accompanied by obstacles such as gravel, water, and muddy ground. The four-track design increases the ground contact area of the equipment, enhances its ability to pass through, and ensures continuous and safe anchoring operations. Compared to dual-tracked equipment, four-tracked equipment can better traverse obstacles, making the robot more adaptable to various tunnel terrains. The four-tracked system also offers better steering flexibility, allowing for easy turning and maneuvering in narrow tunnels, facilitating operation. The four-tracked system balances the load on the equipment, reducing the pressure on each track and effectively minimizing damage to the tunnel floor, thus extending the tunnel's service life, especially suitable for soft ground and long-distance construction tunnels. The four-tracked equipment incorporates an advanced automation and intelligent control system, precisely controlling the movement of each track, resulting in smoother operation in complex terrain and the ability to adjust operations based on real-time terrain conditions, improving work efficiency. The tracks distribute the load, reducing friction and wear between the ground and the equipment, extending its service life. Furthermore, the four-tracked system allows the equipment to continue operating even with partial track failures, reducing downtime caused by equipment maintenance.

Figure 23 The laser radar positioning module 3 is bolted to the gantry column 30. The laser radar positioning module 3 is crucial in the operation of the automatic anchoring robot for full-section coal mine roadways, primarily responsible for environmental perception, location positioning, and navigation. First, when the robot starts and enters the coal mine roadway, the laser emitter 85 emits a laser beam to perform a high-precision scan of the surrounding roadway, acquiring real-time three-dimensional environmental data. This data is fed back to the data processing center 84 via the signal feedback sensor 86, generating a detailed three-dimensional roadway model.

It is responsible for accurately locating the anchoring position and providing directional navigation; it can identify obstacles and structural features in the tunnel to ensure that the robot chooses the best travel path and avoids collisions; during the net laying operation, the laser radar positioning module 3 guides the precise movement of the net laying module 7 and the anchoring module 8 by monitoring the relative position of the robot and the target position; it can provide real-time feedback and adjust the actions of the net laying module 7 and the anchoring module 8 to ensure that the anchor net 9 is accurately placed in the predetermined position; for the unanchored area at the junction of the roof and sidewalls, the laser radar positioning module 3 can identify it in time and guide the net laying module 7 and the anchoring module 8 to make remedial measures to ensure uniform coverage of the entire cross section.
[0052] The principle of this invention: The fully automated coal mine roadway anchoring robot of this invention addresses the problems of high labor intensity, low efficiency, and poor safety in coal mine roadway anchoring by employing a series of efficient and automated modules working collaboratively. The robot's walking module 1 is driven by the hydraulic motor 18, providing stable movement. Its positioning function is achieved by the laser radar positioning module 3, which includes the laser emitter 85 and the signal feedback sensor 86. This module is responsible for acquiring real-time three-dimensional data of the roadway, generating a coal mine roadway model through the data processing center 84, and determining the anchoring position and direction. When the robot enters the working area, the net transport module 6 begins to transport the pre-installed anchor net 9 to the laying... Netting module 7; the anchor netting robot 60 of the netting module 7 is responsible for grasping and laying anchor nets 9. The robot includes multiple adjustable motion parts, which can accurately grasp the anchor nets 9 and adjust its posture according to the roadway conditions to ensure effective netting laying on the roof, side walls, and their junctions. At the same time, the anchoring module 8 is activated to drive anchor bolts into the roof, side walls, and their junctions to ensure the stability of the roadway structure. When the number of anchor nets decreases, the netting module 5 is activated to send the anchor nets 9 to the anchor net electromagnetic fixing plate group 45 of the netting transport module 6 for fixing, so that the nets 9 can be transported again for the next laying. The whole process is monitored and controlled by a remote control center to ensure that the robot can complete the anchoring operation of the coal mine roadway efficiently and continuously.
