Detailed Implementation

[0045] The core of this application is to provide a roadway repair machine to improve the efficiency and safety of roadway repair in coal mines.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Traditional coal mine underground roadway support units have a relatively simple function and are difficult to move, requiring the use of transport vehicles or monorail cranes for transport. Meanwhile, coal mine roadways must fulfill critical functions such as ventilation, transportation, and pedestrian access. However, due to geological pressure or mining activities, roadways are prone to deformation or damage, leading to poor ventilation and transportation obstructions, directly impacting mine production efficiency and operational safety. Furthermore, deformed or damaged roadways may cause safety hazards such as roof falls and spalling, increasing the risk of casualties. To maintain normal mine production, ensure safe production, and extend the service life of roadways, regular repairs of coal mine roadways are necessary.

[0048] During the repair of coal mine roadways, it is necessary to break up the coal and gangue in deformed roadways and repair the roadway faces. Furthermore, although the roadway roof is relatively solid, and the roof of roadways in goaf areas is not prone to collapse, it still poses significant safety hazards. Therefore, it is necessary to simultaneously carry out gangue breaking and anchor breaking operations within the coal mine roadway. Gangue breaking is generally done manually using pneumatic picks, while anchor breaking usually involves manual climbing of ladders to lift and break anchors. This results in high labor intensity, poor safety, and low efficiency in coal mine roadway repair.

[0049] Therefore, such as Figure 1 As shown in the figure, this application discloses a roadway repair machine 100, including a base 10, a support 20, a walking component 30, a first lifting drive component 40, an anchor breaking component 50, and a rock breaking component 60. By integrating the rock breaking component 60 and the anchor breaking component 50 into the roadway repair machine 100, manpower is saved and the efficiency and safety of roadway repair in coal mines are improved. At the same time, the liftable support 20 can support the roof of the roadway, thereby playing a supporting role, expanding the application of the roadway repair machine 100 and enriching its functionality.

[0050] The following will combine Figures 1 to 8 The tunnel repair machine 100 disclosed in the embodiments of this application will be explained and described in detail.

[0051] Among them, such as Figure 1 and Figure 2 As shown, the support 20 can be mounted on the base 10, and the support 20 can be raised and lowered on the base 10 to support the roof of the tunnel. Meanwhile, as... Figure 3 and Figure 4As shown, the walking assembly 30 can be installed on both sides of the base 10 to drive the roadway repair machine 100 to move within the roadway. The first lifting drive component 40 is installed on the base 10 and can drive the walking assembly 30 to lift. When the roadway repair machine 100 is not in operation, it can be moved to a location requiring support, such as the roadway advance area, via the walking assembly 30. The first lifting drive component 40 drives the walking assembly 30 to lift, at which point the bottom wall of the base 10 can contact the ground or other supporting surfaces, and the roof of the roadway is supported by the bracket 20, thus providing support for the roadway advance area. It should be noted that the roadway advance area mainly refers to the area where the transport roadway, track roadway, and cut-in face intersect. Due to the disturbance caused by the fully mechanized mining face, the roof pressure in the roadway advance area is high, requiring reinforced support.

[0052] like Figure 1 and Figure 2 As shown, the anchor breaking component 50 can be mounted on the support 20, allowing the support 20 to lift the anchor breaking component 50 to the anchor position on the roadway roof. This allows the anchor breaking component 50 to break the anchor on the roadway roof without requiring manual climbing of ladders to lift the anchor breaking device. Simultaneously, the rock breaking component 60 can be mounted on the base 10. The rock breaking component 60 can be used to break and repair the floor bulges or sidewalls of coal mine excavation roadways, saving manpower and improving the efficiency of coal mine excavation roadway repair.

[0053] In some embodiments, the base 10 may include a bottom plate, a top plate, and two side plates. The side plates may have a T-shaped structure, with the horizontal sections of the side plates parallel to and close to the ground or other supporting surfaces. The top and bottom of the two side plates may be welded to the top plate and the bottom plate, respectively, to ensure the overall strength and stability of the base 10.

[0054] In some embodiments, such as Figure 1 As shown, the support frame 20 may include a top beam 21 and vertical jacks 22. The vertical jacks 22 may include two arranged side-by-side, with their fixed ends connected to the base plate of the base 10 and secured to the two side plates of the base 10 via clamps 23. These clamps are positioned at the two ends of the top plate of the base 10 to prevent overturning and ensure the stability of the support frame 20. Simultaneously, the movable ends of the two vertical jacks 22 are connected to both ends of the top beam 21, allowing the top beam 21 to be raised and lowered via the two vertical jacks 22. This, in turn, supports the roof of the roadway via the top beam 21, providing a support function.

[0055] In some embodiments, such as Figure 1 and Figure 2As shown, the first lifting drive component 40 can be a lifting cylinder, and the fixed end of the lifting cylinder can be installed on the side plate of the base 10. The movable end of the lifting cylinder can be connected to the traveling component 30, so that the traveling component 30 can be lifted and lowered through the movable end of the lifting cylinder, thereby enabling the roadway repair machine 100 to switch between two working modes: movement and support. It should be noted that the first lifting drive component 40 can also be a lead screw motor, a worm gear mechanism, or a lifting cylinder, etc., to drive the traveling component 30 to lift and lower.

[0056] In some embodiments, such as Figure 8 As shown, the traveling assembly 30 may include a track assembly 31, and the track assembly 31 may be provided with a connecting seat 311 connected to the first lifting drive component 40. The track assembly 31 may include a track frame, track plates, drive wheels, guide wheels, support rollers, and carrier rollers. Track plates may contact the ground, and adjacent track plates are connected by track pins to form track links. Drive wheels may be connected to the track frame and mesh with track links to transmit power. Guide wheels may be installed at the front or rear end of the track frame to guide the movement direction of the track links and ensure normal operation. Support rollers may be installed on the track frame via bearings or brackets to support the weight of the equipment and distribute the load evenly on the track links. Carrier rollers may be installed on the upper part of the track frame to support the upper track links and prevent them from sagging. The connecting seat 311 can be located inside the track frame, i.e., on opposite sides of the two track assemblies 31, so as to be connected to the first lifting drive 40 via the connecting seat 311.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, the tunnel repair machine 100 may also include a guide assembly 70. Among them, such as... Figure 1 As shown, the guide assembly 70 may include a guide post 71 and a guide cylinder 72 that cooperates with the guide post 71, and one of the traveling assembly 30 and the base 10 is provided with the guide post 71, while the other is provided with the guide cylinder 72, i.e. Figure 1 and Figure 8 As shown, the guide post 71 can be disposed on the walking component 30, and the guide cylinder 72 can be disposed on the base 10, so that the guide post 71 can slide within the guide cylinder 72, thereby guiding the lifting and lowering action of the walking component 30 and ensuring the stability of the lifting and lowering action of the walking component 30; the guide post 71 can also be disposed on the base 10, and the guide cylinder 72 can be disposed on the walking component 30, so that the guide post 71 can slide within the guide cylinder 72, thereby guiding the lifting and lowering action of the walking component 30 and ensuring the stability of the lifting and lowering action of the walking component 30.

[0058] In some embodiments, when the first lifting drive component 40 is a lifting cylinder, the lifting cylinder can be connected to the emulsion high-pressure system in the coal mine via a connecting pipeline. This allows the emulsion high-pressure system to provide hydraulic power to the lifting cylinder, thereby driving the walking assembly 30 to lift. Furthermore, the column jack 22 can also be connected to the emulsion high-pressure system in the coal mine via a connecting pipeline. This allows the emulsion high-pressure system to provide hydraulic power to the column jack 22, thereby driving the top beam 21 to lift.

[0059] In some embodiments, such as Figure 1 and Figure 2 As shown, the top beam 21 is provided with a mounting bracket 211 facing rearward in the moving direction of the roadway repair machine 100. The mounting bracket 211 is located below the top beam 21 and extends rearward from the top beam 21. The anchor breaking component 50 can be installed on the mounting bracket 211, and the rock breaking component 60 can be installed in front of the base 10 to avoid mutual interference between the anchor breaking component 50 and the rock breaking component 60.

[0060] In some embodiments, such as Figure 1 , Figure 5 and Figure 6As shown, the anchor breaking assembly 50 may include an anchor breaking mounting base 51, a telescopic arm 52, and a breaker 53. The anchor breaking mounting base 51 is mounted on a mounting bracket 211 of the top beam 21 via a first slewing bearing 511, and is rotated by a first slewing drive member 5111 on the mounting bracket 211. The fixed end of the telescopic arm 52 is hinged to the anchor breaking mounting base 51, and the anchor breaking mounting base 51 is provided with a first rotary drive member 512 capable of driving the telescopic arm 52 to rotate, so that the fixed end of the telescopic arm 52 can rotate around a hinged position with the anchor breaking mounting base 51. Simultaneously, the breaker 53 is hinged to the movable end of the telescopic arm 52, and the movable end of the telescopic arm 52 is provided with a second rotary drive member 521 capable of driving the breaker 53 to rotate, so that the second rotary drive member 521 can drive the breaker 53 to rotate around a hinged position with the movable end of the telescopic arm 52. Furthermore, the telescopic arm 52 is equipped with a telescopic drive component 522 that can drive the movable end of the telescopic arm 52 to extend or retract. When it is necessary to break the anchorage of the roadway roof, the column jack 22 can drive the anchorage breaking component 50 on the top beam 21 to the height of the anchorage on the roadway roof. The telescopic drive component 522 of the anchorage breaking component 50 drives the telescopic arm 52 to extend, and the first rotary drive component 5111 drives the anchorage breaking mounting seat 51 to rotate, so that the breaker 53 moves to the anchorage position on the roadway roof. At this time, the first rotary drive component 512 and the second rotary drive component 521 can cooperate with each other to make the breaker 53 fit on the outside of the anchorage on the roadway roof, and the breaker 53 breaks the anchorage on the roadway roof. It should be noted that the first rotary drive component 5111, the first rotating drive component 512, the second rotating drive component 521, and the telescopic drive component 522 can be driven by hydraulic cylinders, or by pneumatic cylinders, motors, etc. Furthermore, the breaker 53 can adopt a conventional breaker structure used for cutting roadway roof anchors, which will not be elaborated upon here.

[0061] like Figure 1 , Figure 2 and Figure 7 As shown, the coal crushing assembly 60 may include a robotic arm assembly 61 and a breaker hammer 62. The robotic arm assembly 61 may be connected to the base 10, and the breaker hammer 62 is connected to the robotic arm assembly 61 so that the robotic arm assembly 61 drives the breaker hammer 62 to crush the coal and gangue.

[0062] In some embodiments, such as Figure 1 , Figure 2 and Figure 7As shown, the robotic arm assembly 61 may include a fixed base 611, a first connecting arm 612, a second connecting arm 613, and a third connecting arm 614. A crushing mounting base 12 may be provided at the front end of the two side plates of the base 10, and the fixed base 611 can be mounted on the end face of the crushing mounting base 12 of the base 10 via a second slewing bearing 6111. A second slewing drive member 6113 capable of driving the fixed base 611 to rotate may be provided on the crushing mounting base 12, so that the second slewing drive member 6113 can drive the fixed base 611 to rotate. The first connecting arm 612 can be engaged in a slot in the fixed base 611, and the fixed base 611 is provided with a second lifting drive member 6112 capable of driving the first connecting arm 612 to rise and fall, so that the second lifting drive member 6112 can drive the first connecting arm 612 to rise and fall. The second connecting arm 613 is hinged to the first connecting arm 612, and the first connecting arm 612 is provided with a first swing drive member 6121 that can drive the second connecting arm 613 to swing, so that the first swing drive member 6121 can drive the second connecting arm 613 to swing. The third connecting arm 614 is hinged to the second connecting arm 613, and the second connecting arm 613 is provided with a second swing drive member 6131 that can drive the third connecting arm 614 to swing, so that the second swing drive member 6131 can drive the third connecting arm 614 to swing. The breaker hammer 62 is hinged to the third connecting arm 614, and the third connecting arm 614 is provided with a flip drive member 6141 that can drive the breaker hammer 62 to flip, so that the breaker hammer 62 can be flipped through the flip drive member 6141. Through the cooperation of the fixed base 611, the first connecting arm 612, the second connecting arm 613, and the third connecting arm 614, the breaker hammer 62 can be adjusted with multiple degrees of freedom, thereby facilitating the crushing of coal and gangue. It should be noted that the second rotary drive 6113, the second lifting drive 6112, the first swing drive 6121, the second swing drive 6131 and the tilting drive 6141 can be driven by hydraulic cylinders, or by pneumatic cylinders, motors and other types of drives.

[0063] In some embodiments, the first connecting arm 612 may have an approximately T-shaped structure, and the first connecting arm 612 includes a first connecting portion and a second connecting portion disposed perpendicularly to the first connecting portion. One end of the first connecting portion may be connected to the fixed end of the first swing drive member 6121, and the other end of the first connecting portion may be connected to the movable end of the second lifting drive member 6112. Simultaneously, the second connecting portion may be engaged in a slot in the fixed base 611 to limit the movement of the first connecting arm 612, and the side wall of the second connecting portion may be provided with an ear plate. The second connecting arm 613 may be hinged to the ear plate, so that the movable end of the second lifting drive member 6112 can drive the first connecting arm 612, the second connecting arm 613, and the third connecting arm 614 to move up and down.

[0064] In some embodiments, such as Figure 2 and Figure 7 As shown, the movable end of the tilting drive 6141 can be connected to the breaker 62 via the connecting rod 6142, and the movable end of the tilting drive 6141 can be connected to the third connecting arm 614 via the swing rod 6143, thereby ensuring the stability of the tilting drive 6141 in driving the breaker 62 to tilt.

[0065] The roadway repair machine 100 disclosed in this application can move within a coal mine excavation roadway via walking components 30 mounted on both sides of the base 10. It can also use a rock-breaking component 60 to break and repair the floor bulges or sidewalls of the excavated roadway, and a rock-breaking component 50 to break and cut the anchors on the roadway roof. Furthermore, the roadway repair machine 100 can be moved to a location requiring support, and the roof of the roadway can be supported by a bracket 20, thereby providing support for the advanced areas of the roadway.

[0066] The roadway repair machine 100 disclosed in this application integrates both a rock-breaking component 60 and an anchor-breaking component 50, which saves manpower and improves the efficiency and safety of roadway repair in coal mines. At the same time, the liftable support 20 can support the roof of the roadway, thereby playing a supporting role, expanding the application of the roadway repair machine 100 and enriching its functionality.

[0067] like Figure 1 and Figure 2 As shown, the roadway repair machine 100 may further include a power component 90 capable of driving the movement of the traveling component 30 and the operation of the rock breaking component 60 and the anchor breaking component 50. A power mounting base 11 for mounting the power component 90 may be provided at the rear end of the two side plates of the base 10. The power mounting base 11 may be welded to the two side plates of the base 10 so that the power component 90 can be mounted at the rear end of the base 10. This allows it to achieve a balanced state with the rock breaking component 60 located at the front end of the base 10 while driving the movement of the traveling component 30 and the operation of the rock breaking component 60 and the anchor breaking component 50, thus preventing the roadway repair machine from overturning.

[0068] In some embodiments, such as Figure 1 and Figure 2 As shown, the power assembly 90 may include an air source interface, a pneumatic motor, and an oil pump 91. The pneumatic motor is connected to the oil pump 91 via a gearbox, and the air source interface can connect the pneumatic motor to an air pipeline in the underground coal mine roadway, thereby providing power through the air pipeline in the underground coal mine roadway.

[0069] In some embodiments, such as Figure 1 and Figure 2As shown, the power assembly 90 may also include a gas source processing triplet 92, which can filter and pressurize the gas entering the pneumatic motor from the gas pipeline in the underground coal mine roadway, so that the gas supplied by the gas pipeline in the underground coal mine roadway is high-pressure gas, thereby providing high-pressure power to the pneumatic motor.

[0070] In some embodiments, such as Figure 1 and Figure 2 As shown, a first control valve 24 capable of controlling the lifting and lowering of the support 20 can be installed at the rear end of the base 10 to control the support function of the support 20. Simultaneously, a second control valve 80 capable of controlling the operation of the rock-breaking assembly 60 and the anchor-breaking assembly 50 can be installed at the rear end of the base 10. Furthermore, a remote control receiver capable of receiving remote control signals can be installed at the rear end of the base 10, allowing operators to remotely control the roadway repair machine, ensuring the safety of coal mine roadway repair.

[0071] In some embodiments, when the roadway repair machine 100 needs to work, the lifting cylinder and the column jack 22 can be connected to the emulsion inlet and outlet pipelines of the high-pressure emulsion system in the coal mine. Simultaneously, the air source interface at the rear end of the base 10 is connected to the air pipeline in the underground roadway of the coal mine to access high-pressure air. By controlling the first control valve 24 of the support 20, the support 20 in the supported state is lowered to its lowest position. Then, the lifting cylinder extends, causing the track assembly 31 to descend from an ungrounded state to contact the ground or other supporting surface until the base 10 is lifted. At this time, the track assembly 31 can drive the roadway repair machine 100 to move. By opening the main valve of the air pipeline in the underground roadway of the coal mine, compressed air can drive the pneumatic motor, converting air energy into rotational kinetic energy. Simultaneously, the pneumatic motor can be connected to the oil pump 91 through the gearbox, driving the oil pump 91 to work and generate hydraulic power. The track assembly 31 can be moved to the location requiring excavation and crushing via remote control. The remote control operates the robotic arm assembly 61 to adjust its angle, and the breaker hammer 62 is used to crush the bottom drum, gangue, etc. The roadway repair machine 100 is moved to the location requiring anchor breaking, and the remote control operates the telescopic arm 52 to adjust its angle, so that the breaker 53 engages with the anchor cable lock and breaks the anchor cable lock, rendering it ineffective and completing the anchor breaking operation. After the roadway repair machine 100 has completed its operation, it can be moved to the location in the roadway that requires support. The track assembly 31 is lifted by the lifting cylinders on both sides until it is detached from the ground or other supporting surface. At this time, the base 10 contacts the ground or other supporting surface.
