[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figures 1 to 10 As shown, one embodiment of the present invention provides a coal mine tunneling and anchoring integrated device, which includes a body 11, a support device 21, and an adjustment assembly 31. The support device 21 includes a support frame 211 and a guard plate assembly 61. The support frame 211 is connected to the body 11 and is rotatable relative to the body 11 about a straight line in the width direction of the body 11. The support frame 211 includes a first frame 2111 and a second frame 2112 connected to each other. The second frame 2112 is rotatable relative to the first frame 2111 about a straight line in the length direction of the body 11. The guard plate assembly 61 is disposed on the second frame 2112. The adjustment assembly 31 includes a first driver. The output end of the first driver is connected to the second frame 2112 for transmission. The first driver is used to drive the second frame 2112 to rotate relative to the first frame 2111, so that the guard plate assembly 61 adapts to the inclination angle of the roadway roof.

[0041] Specifically, the machine body 11, as the core load-bearing structure of the entire equipment, provides a stable installation foundation and operating space for other components. The support device 21 is connected to the machine body 11 via a support frame 211, and the support frame 211 can rotate relative to the machine body 11 around the straight line of the width direction of the machine body 11. This allows the support frame 211 to adjust the height of the protective plate assembly 61 in the coal mine roadway according to the roof height, ensuring that the support device 21 can accurately position itself to the required support area. In addition, the integrated tunneling and anchoring equipment for coal mines provided by this invention also includes a cutting section 12, a transfer section 13, an onboard dust removal section 14, a transportation section 15, and a control system.

[0042] The support frame 211 can be divided into a first frame 2111 and a second frame 2112 connected to each other. The second frame 2112 can rotate relative to the first frame 2111 around the line along the length of the machine body 11, thus forming a bidirectional rotation adjustment mechanism. Regardless of whether the roadway roof is horizontal, inclined, or has complex curved surface changes, the support frame 211 can adjust itself to the optimal position through its own rotation, preparing for subsequent support work. The protective plate assembly 61 is installed on the second frame 2112 and is the part that directly contacts the roadway roof and provides support force. It can withstand the pressure applied by the roadway roof, effectively preventing roof collapse and ensuring the safety of workers and equipment.

[0043] When the roof of the coal mine roadway tilts, the first actuator activates. Based on a preset program or real-time monitoring of the roof angle, the first actuator drives the second frame 2112 to rotate relative to the first frame 2111. Through this rotational adjustment, the protective plate assembly 61 can quickly adapt to the tilt angle of the roadway roof, maintaining good contact with the roof and providing effective support.

[0044] In summary, the coal mine tunneling and anchoring integrated equipment provided in one embodiment of the present invention achieves efficient integration of tunneling and support through the coordinated work of the machine body 11, support device 21 and adjustment component 31, enabling the equipment to flexibly adapt to various complex conditions in coal mine roadways and providing a safer and more efficient solution for coal mining.

[0045] like Figure 1 , Figure 2 As shown, in some embodiments, the coal mine tunneling and anchoring integrated equipment also includes a controller and a plurality of adjustable support members 41. The two ends of the adjustable support members 41 are respectively connected to the support frame 211 and the machine body 11. The plurality of adjustable support members 41 are respectively arranged on both sides of the machine body 11 along the width direction of the machine body 11. A portion of the plurality of adjustable support members 41 forms a first driver. The controller is used to adjust the extension length of each adjustable support member 41 so that the second frame 2112 rotates relative to the first frame 2111.

[0046] Specifically, the two ends of the adjustable support member 41 are respectively connected to the support frame 211 and the machine body 11. In terms of layout, multiple adjustable support members 41 are arranged along the width direction of the machine body 11 on both sides of the machine body 11. Some of these adjustable support members 41 are combined together through electrical connections or mechanical cooperation to form the first drive. The controller can precisely adjust the extension length of each adjustable support member 41 according to a preset degree or real-time received instructions, thereby changing the support state of the adjustable support member 41 on the support frame 211, causing the second frame 2112 to rotate relative to the first frame 2111, providing greater flexibility and adaptability for the operation of the equipment.

[0047] Furthermore, the controller can also control the extension length of some of the adjustable support members 41 among the multiple adjustable support members 41, so that the support frame 211 rotates relative to the fuselage 11 in the width direction of the fuselage 11.

[0048] In other embodiments of the present invention, the first driver may also be configured as an electric motor, hydraulic motor or other components, as long as it can drive the second frame 2112 to rotate relative to the first frame 2111.

[0049] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the first frame 2111 has a first plate 21111, the second frame 2112 has a second plate 21121, the first plate 21111 and the second plate 21121 are arranged in parallel, and a first rotating shaft 2113 is connected between the first plate 21111 and the second plate 21121. The first rotating shaft 2113 extends along the width direction of the body 11.

[0050] Specifically, the first plate 21111 and the second plate 21121 are rotatably connected by the first rotating shaft 2113, which enables relative rotation between the second frame 2112 and the first frame 2111.

[0051] Furthermore, a fastener 2114 connects the first plate 21111 and the second plate 21121, the fastener 2114 being used to restrict the rotation of the second frame 2112 relative to the first frame 2111. When the second frame 2112 does not need to rotate relative to the first frame 2111, the fastener 2114 can connect the first plate 21111 and the second plate 21121 together, forming a rigid integral structure. When it is necessary to adjust the position of the second frame 2112 relative to the first frame 2111, the operator can temporarily release the restriction of the fastener 2114 on the rotation of the first plate 21111 and the second plate 21121, allowing the second frame 2112 to rotate flexibly and accurately around the first pivot 2113.

[0052] In this embodiment, both the first plate 21111 and the second plate 21121 extend along the width direction of the body 11, thereby allowing for better control of the rotation between the second frame 2112 and the first frame 2111. Both the first plate 21111 and the second plate 21121 are provided with a rotation hole 2115 and a limiting hole 2116, with the first rotating shaft 2113 passing through the rotation hole 2115. The fixing member 2114 is a cylindrical structure, passing through the limiting hole 2116 to achieve the installation and fixation of the first plate 21111 and the second plate 21121.

[0053] Furthermore, there are two limiting holes 2116, which are symmetrically arranged on both sides of the rotating hole 2115, and two fixing members 2114 are provided accordingly, so as to achieve double limiting.

[0054] like Figure 1 and Figure 2 As shown, in this embodiment, the adjustable support member 41 can be disposed at the front end of the support frame 211, and the rear end of the support frame 211 can be hinged to the machine body 11. Two adjustable support members 41 can be provided, located on the left and right sides of the support frame 211 respectively. During the adjustment of the two adjustable support members 41 by the controller, if the extension lengths of the two adjustable support members 41 are the same, the adjustable support members 41 can drive the support frame 211 to rotate relative to the machine body 11 around the width direction of the machine body 11; if the extension lengths of the two adjustable support members 41 are different, due to the height difference between their extension lengths, the second frame 2112 rotates relative to the first frame 2111, thereby supporting the roof plate at different inclination angles. It should be noted that the inclination angle referred to here is the inclination or unevenness of the tunnel roof plate in the left-right direction of the tunnel, and the connection between the adjustable support member 41 and the support frame 211 can also be referred to... Figure 5 .

[0055] Furthermore, the second frame 2112 also includes a first sub-frame 213 and a second sub-frame 214. The first sub-frame 213 is connected to the first frame 2111, and the second sub-frame 214 is rotatably connected to the first sub-frame 213 about the width direction of the fuselage 11. A limiting member 215 is provided between the first sub-frame 213 and the second sub-frame 214 to restrict rotation between them. One end of the adjustable support member 41 is connected to the fuselage 11, and the other end of the adjustable support member 41 can be connected to the second sub-frame 214.

[0056] In other words, a second rotating shaft 218 is provided between the first sub-frame and the second sub-frame. When the two adjustable support members 41 are raised or lowered synchronously, the adjustable support member 41 can drive the second sub-frame 214 as needed, or drive the support frame 211 where the second frame 2112 is located as a whole, thus having more diverse structural forms and being able to adapt to the usage needs of different environments.

[0057] like Figure 5 and Figure 6 As shown, in some embodiments, the first frame 2111 has two support legs 216, which are spaced apart along the width direction of the fuselage 11. The second frame 2112 has two connecting arms 217, which are connected to the support legs 216 in a one-to-one correspondence. At least one of the two sets of support legs 216 and connecting arms 217 is provided with an adjustable support member 41 between them.

[0058] Specifically, two connecting arms 217 and two supporting legs 216 are connected to form two sets. When an adjustable support 41 is provided between one set of supporting legs 216 and connecting arms 217, the controller can adjust the extension length of the adjustable support 41 to adjust the position and attitude of the second frame 2112 relative to the first frame 2111.

[0059] Furthermore, the connecting arm 217 also includes a body 2171, a screw 2172, and a screw seat 2173. The screw 2172 and the screw seat 2173 are connected by a thread. One of the screw 2172 and the screw seat 2173 is connected to the body 2171, and the other of the screw 2172 and the screw seat 2173 is connected to the support leg 216.

[0060] The screw 2172 and the screw seat 2173 are connected by threads. By rotating the screw 2172, the screws on both screws engage with each other. As rotation continues, the screw 2172 will move deeper into or out of the screw seat 2173, thereby achieving relative displacement between them. In terms of specific connection, the screw seat 2173 can be fixed to the body 2171, and one end of the screw 2172 can be connected to the support leg 216. Of course, in some embodiments, the screw 2172 can also be connected to the body 2171, and the corresponding screw seat 2173 is connected to the support leg 216.

[0061] In other words, when an adjustable support member 41 is provided between one of the two sets of support legs 216 and connecting arms 217, the controller can control the extension length of the adjustable support member 41 to make the second frame 2112 rotate around the screw 2172 on the other connecting arm 217, thereby achieving the tilt angle adjustment of the guard plate assembly 61. Similarly, when adjustable support members 41 are provided between both sets of support legs 216 and connecting arms 217, the above effect can also be achieved by controlling the difference in the extension length of the two adjustable support members 41, which will not be elaborated further here.

[0062] It should be noted that the structure of the adjustable support 41 can include hydraulic drive and electric drive depending on the driving method; and can be hydraulic rod-shaped or transmission screw-shaped depending on the transmission method. Therefore, the adjustable support 41 at the front end of the mounting plate 611 and the adjustable support 41 between the support leg 216 and the connecting arm 217 can be selected according to the size requirements, which will not be described in detail here.

[0063] like Figure 2 , Figure 7 and Figure 8As shown, in some embodiments, the guard plate assembly 61 includes a mounting plate 611 and a sliding top plate 51, with a ball connection between the mounting plate 611 and the sliding top plate 51, and an elastic element 617 between the mounting plate 611 and the sliding top plate 51.

[0064] In this embodiment, the sliding roof plate 51 is movable relative to the body 2171 of the second frame 2112 along the length of the machine body 11, extending towards the tunneling face. This allows the sliding roof plate 51 to automatically adjust its position according to the actual conditions of the tunnel roof, always maintaining contact with the tunnel roof. The ball connection refers to the installation of a ball socket 612 and a connecting ball 511 on the mounting plate 611 and the sliding roof plate 51, respectively. The connecting ball can rotate omnidirectionally within the ball socket, giving the mounting plate 611 three degrees of rotational freedom relative to the sliding roof plate 51. This better adapts to uneven surfaces and angle changes on the tunnel roof, ensuring that other components on the guard plate assembly 61 always maintain a suitable working angle.

[0065] The elastic element plays multiple important roles between the mounting plate 611 and the sliding top plate 51. First, the elastic element can act as a buffer and shock absorber. During coal mine tunneling, the equipment is subjected to various vibrations and impacts, such as the tunneling vibration of the tunneling head. At this time, the elastic element can absorb and dissipate these vibrations and impacts through its own elastic deformation, reducing the vibration transmitted to the guard plate assembly 61 and the entire equipment.

[0066] Secondly, the elastic element can provide a certain preload. By adjusting the preload of the elastic element, the mounting plate 611 and the sliding top plate 51 can maintain appropriate contact pressure, ensuring that the guard plate assembly 61 will not loosen or shift due to vibration or external force during operation.

[0067] Furthermore, the elastic element also has a certain self-adjusting capability. When the pressure or shape of the tunnel roof changes, the elastic element can automatically adjust its elastic deformation according to the actual situation, so that the mounting plate 611 and the guard plate assembly 61 can always maintain good contact with the tunnel roof, thereby improving the adaptability and working effect of the guard plate assembly 61.

[0068] In this embodiment, the mounting plate 611 is provided with a ball socket 612, and the sliding top plate 51 is provided with a connecting ball 511. The ball socket 612 is rotatably disposed in the connecting ball 511 to realize the ball connection between the mounting plate 611 and the sliding top plate 51.

[0069] like Figure 7As shown, in some embodiments, the guard plate assembly 61 further includes an outer sleeve 613, an inner sleeve 614, and a front guard plate 615. The outer sleeve 613 is connected to the mounting plate 611, the inner sleeve 614 is slidably connected to the outer sleeve 613, and the front guard plate 615 is hinged to the inner sleeve 614. A second driver 616 is provided between the front guard plate 615 and the inner sleeve 614. The second driver 616 is used to drive the front guard plate 615 to rotate relative to the inner sleeve 614. A sixth driver is provided between the outer sleeve and the inner sleeve. The sixth driver is used to drive the inner sleeve to slide relative to the outer sleeve.

[0070] Specifically, one end of the outer sleeve 613 can be tightly connected to the mounting plate 611 by welding, bolting, or other methods to ensure that the two will not loosen due to equipment vibration or external forces. The front guard plate 615 can contact the coal mine roadway or extend towards the working face to support the front of the equipment. The second drive 616 can adjust the rotation angle of the front guard plate 615 according to actual operational needs, providing reliable protection for the equipment and personnel.

[0071] Optionally, the sixth actuator may be configured as a component such as a hydraulic cylinder or a linear motor.

[0072] Through research by the technical personnel of this invention, it has been found that the support device 21 in the coal mine tunneling and anchoring integrated equipment provided by this invention can realize forward-looking temporary support, achieve zero open roof in advance temporary support, and provide 2×200kN initial support force, effectively ensuring the safety of operators and equipment, and solving the problem that the existing temporary support in the market (which can only provide 50kN initial support force) cannot truly cope with large roof collapses.

[0073] like Figure 1 , Figure 9 , Figure 10 and Figure 11 As shown, in some embodiments, the coal mine tunneling and anchoring integrated equipment also includes an anchoring device 71. The anchoring device 71 includes an installation platform 711, a first anchoring drill 712, and a multi-directional adjustment mechanism 713. The installation platform 711 is located on the machine body 11, and the multi-directional adjustment mechanism 713 is located between the installation platform 711 and the first anchoring drill 712. The multi-directional adjustment mechanism 713 is used to adjust the anchoring position of the first anchoring drill 712.

[0074] Specifically, the mounting platform 711 serves as the basic support structure for the anchoring device 71. The multi-directional adjustment mechanism 713 is located between the mounting platform 711 and the first anchoring drill 712. It is a component that enables the anchoring device 71 to flexibly adjust its anchoring position. It has the function of adjusting in multiple directions, allowing the first anchoring drill 712 to make precise position adjustments in multiple directions such as horizontal, vertical and inclined.

[0075] Furthermore, the multi-directional adjustment mechanism 713 includes a rotary frame 7131, a first sliding frame 7132, and a second sliding frame 7133. The rotary frame 7131 is located between the first sliding frame and the mounting platform 711. The rotation axis of the rotary frame 7131 is parallel to the length direction of the machine body 11. The first sliding frame 7132 is slidably connected to the rotary frame 7131 along a first direction. The second sliding frame 7133 is slidably located on the first sliding frame 7132 along a second direction. The straight line containing the first direction is perpendicular to the straight line containing the second direction. The first anchoring drill 712 is located on the second sliding frame 7133.

[0076] The rotation axis of the slewing frame 7131 is parallel to the length direction of the machine body 11, allowing the first anchoring drill 712 to rotate freely 360 degrees around this axis in the horizontal plane. In practical applications, when anchoring at different locations on the tunnel wall, the rotation of the slewing frame 7131 can quickly adjust the first anchoring drill 712 to the appropriate angle.

[0077] The first sliding frame 7132 is slidably connected to the rotary frame 7131 along the first direction, and the sliding direction of the second sliding frame 7133 is perpendicular to that of the first sliding frame 7132, so that the multi-directional adjustment mechanism 713 can achieve independent position adjustment in two mutually perpendicular directions, further expanding the adjustment range of the first anchoring drill rig 712.

[0078] During actual operation, operators can input the target position parameters that the first anchoring drill rig 712 needs to reach into the controller, based on the geological conditions and design requirements of the tunnel. After receiving the parameters, the controller first controls the rotation of the slewing frame 7131 to adjust the first anchoring drill rig 712 to a suitable angle. Then, based on the displacement requirements in the directions of the first sliding frame 7132 and the second sliding frame 7133, the controller adjusts the movement of the first sliding frame 7132 and the second sliding frame 7133 accordingly. This not only achieves the anchoring of the roof but also the anchoring of the sidewalls.

[0079] In this embodiment, there are two first anchoring drills 712 and two corresponding second sliding frames 7133. The two first anchoring drills 712 are arranged one-to-one on the second sliding frames 7133, so that each first anchoring drill 712 can be adjusted independently. In particular, the first anchoring drill 712 located on the side closer to the middle of the roadway in the left-right direction of the roadway can be accurately moved to the middle area of ​​the roadway to realize the anchoring operation of the middle area of ​​the roadway.

[0080] Furthermore, both the first sliding frame and the second sliding frame include a first guide rail and a first slide block. The first slide block is slidably disposed on the first guide rail, and a fifth driver is provided between the first slide block and the first guide rail. The fifth driver is used to drive the first slide block to slide relative to the first guide rail. In other words, the first sliding frame and the second sliding frame are structurally similar.

[0081] Furthermore, the multi-directional adjustment mechanism 713 also includes a correction component 714, which is located between the first anchoring drill rig 712 and the second sliding frame 7133. The correction component 714 is used to drive the anchor bolt assembly to swing relative to the second sliding frame 7133. That is, the first anchoring drill rig 712 and the second sliding frame 7133 are hinged, and the correction component 714 can fine-tune the position of the first anchoring drill rig 712 after the multi-directional adjustment mechanism 713 has moved into place, so that it can adapt to local changes in the roadway wall.

[0082] like Figure 1 , Figure 9 and Figure 11 As shown, in this embodiment, two first anchoring drills 712 are provided on the second sliding frame 7133, and two anchoring devices 71 are provided on the machine body 11. Each anchoring drill can move independently in the front-back, left-right, and lateral directions through the multi-directional adjustment mechanism 713 to meet the requirements of the spacing between the top and bottom sides, the anchoring angle, and the hole-making operation.

[0083] The workbench has a first connecting plate and a second connecting plate connected to each other, and the first connecting plate and the second connecting plate are arranged in a similar L-shape. The first connecting plate is arranged parallel to the horizontal plane of the machine body, and the second connecting plate extends obliquely from the second connecting plate toward the roof of the tunnel along the height direction of the machine body. The rotary shaft is located on the second connecting plate.

[0084] The first guide rail of the first sliding frame can be set on the rotary seat, the first slide block of the first sliding frame is slidably set on the first guide rail, the first guide rail of the second sliding frame is set on the first slide block of the first sliding frame, and the first anchoring drill is set on the first slide block of the second sliding frame.

[0085] like Figure 11 As shown, in some embodiments, the mounting platform 711 includes a lifting mechanism 7111, which drives the multi-directional adjustment mechanism 713 and the first anchoring drill 712 to move relative to the machine body 11 along the height direction of the machine body 11. The lifting mechanism 7111 can be a scissor mechanism, comprising a third driver, an upper plate, and multiple hinged connecting rods, with both ends of the connecting rods correspondingly connected to the upper plate and the machine body 11. The fixed end of the third driver is mounted on the machine body 11, and the output end of the third driver can be connected to the upper plate. The third driver can be electrically or hydraulically operated.

[0086] The maximum lifting height of the lifting mechanism 7111 can be set to 350mm to 400mm, such as 350mm, 375mm or 400mm.

[0087] like Figure 11 As shown, in some embodiments, the mounting platform 711 further includes a sliding mechanism 7112, which is used to drive the multi-directional adjustment mechanism 713 and the first anchoring drill 712 to move relative to the machine body 11 along the length of the machine body 11. The sliding mechanism 7112 may include a slide rail, a slider, and a transmission device. The slide rail extends along the length of the machine body 11, and the slider is tightly fitted with the slide rail, allowing it to slide smoothly on the slide rail. The transmission device uses a gear and rack drive or chain drive, etc., to transmit power to the slider, causing it to move along the slide rail, thereby transporting the first anchoring drill 712, the multi-directional adjustment mechanism 713, and the correction component 714 to the facing position (the tunneling face of a coal mine roadway). The sliding stroke of the sliding mechanism 7112 is set to 1.5 meters to 2.0 meters, for example, 1.5 meters, 1.75 meters, or 2.0 meters.

[0088] In this embodiment, the lifting mechanism 7111 and the sliding mechanism 7112 are used in combination. The slide rail of the sliding mechanism 7112 can be set on the plate above the lifting mechanism 7111, so that the first anchoring drill rig 712 in the anchoring device 71 can be moved freely in the tunneling direction and height direction of the coal mine roadway as needed.

[0089] Furthermore, the integrated tunneling and anchoring equipment for coal mines also includes a second anchoring drill rig 715. The second anchoring drill rig 715 can include either an upper side anchoring drill rig or a lower side anchoring drill rig. Specifically, in the height direction of the machine body, the second anchoring drill rig 715 can be positioned at 1.6 meters or 2.7 meters, where 1.6 meters and 2.7 meters refer to the distance between the second anchoring drill rig 715 and the roadway roof. This arrangement of the second anchoring drill rig can, on the one hand, adapt to the anchoring requirements of two or three rows of sidewall spacing in the roadway; on the other hand, it can cooperate with the first anchoring drill rig to form a sidewall-anchoring coordinated support scheme, with the first anchoring drill rig rotating to support the sidewall primarily and the second anchoring drill rig 715 as a supplement, achieving full-section support of the sidewalls.

[0090] In some embodiments, the coal mine tunneling and anchoring integrated equipment also includes a lifting mechanism 716, which can be located between the second anchoring drill 715 and the machine body 11. The lifting mechanism 716 is used to drive the second anchoring drill 715 to move in the height direction of the machine body 11 to adapt to the needs of different anchoring heights.

[0091] Optionally, the lifting mechanism 716 can be configured with a similar structure to the lifting mechanism 7111. The lifting stroke of the lifting mechanism 716 can be set to 2 meters.

[0092] like Figure 12 As shown, in some embodiments, the anchoring device 71 further includes a protective cover 717 and a side support 718. The protective cover is disposed above the mounting platform, and the side support is installed on the side of the protective cover. The side support is used to abut against the side of the roadway to improve the stability of the equipment during operation.

[0093] Furthermore, the side support member 718 includes a side support rod 7181 and a fourth actuator 7182, the fourth actuator being used to move the side support rod to adjust the extension length of the side support rod so that it can abut against the side of the tunnel.

[0094] Furthermore, the side support rod 7181 can be configured as a hydraulic rod or a linear motor, etc.

[0095] Optionally, multiple side support members 718 may be provided, and the multiple side support members 718 are spaced apart along the height direction of the fuselage 11.

[0096] In summary, the coal mine tunneling and anchoring integrated equipment provided by the present invention can be used for both permanent and temporary roadway support through the coordinated use of the lifting mechanism 7111, the sliding mechanism 7112, the multi-directional adjustment mechanism 713 and the first anchoring drill 712. The permanent support can be less than or equal to 0.8 meters, and the temporary support has a zero-open-roof support effect.
