[0054] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0055] As the capacity and efficiency of coal mining gradually improve, the development of tunnel anchoring equipment lags behind that of tunneling, the degree of automation of coal mining machinery is low, and the working conditions of tunneling working faces are relatively complex.

[0056] In the related art, the mining system includes a bolter, a transfer machine, a monorail crane, a drilling and anchoring machine, a self-propelled tail and an anchor drill. The excavation part of the bolter is responsible for tunnel excavation, the bolter is responsible for tunnel anchoring, and the anchor drill is responsible for tunnel supplementation. Since the bolter of the existing mining system is generally installed on the airborne platform of the bolter, it is easy to cause the anchor cable area of ​​the bolter to be limited and inconvenient to move.

[0057] In order to solve at least one of the technical problems existing in the prior art or related technology, the present invention provides an anchor mechanism, which includes an anchor drill, a frame and a swing mechanism, wherein a connecting frame is provided at the bottom of the frame, and the connecting frame is used to connect with a self-moving tail; the swing mechanism is installed on the frame; the anchor drill is installed on the swing mechanism, and the swing mechanism is used to drive the anchor drill to swing on the frame to change the relative position between the anchor drill and the frame. After the anchor mechanism provided by the present application is connected to the self-moving tail through the connecting frame, it can increase its anchor cable area, and through the setting of the swing mechanism, it can also adjust its working position in the tunnel according to the on-site tunnel conditions to meet the requirements of tunnel anchoring.

[0058] The following describes the bolt mechanism, the self-moving tail and the mining system according to some embodiments of the present invention with reference to the accompanying drawings.

[0059] See also Figures 1 to 5 An embodiment of the present invention provides an anchor mechanism, which is applied to a mining system. The anchor mechanism includes an anchor drilling rig 1, a frame 2 and a swing mechanism 3. A connecting frame 4 is provided at the bottom of the frame 2, and the connecting frame 4 is used to connect with a self-moving tail 5; the swing mechanism 3 is installed on the frame 2; the anchor drilling rig 1 is installed on the swing mechanism 3, and the swing mechanism 3 is used to drive the anchor drilling rig 1 to swing on the frame 2 to change the relative position between the anchor drilling rig 1 and the frame 2.

[0060] Here, the anchor drill rig 1 is used to perform drilling operations on the ceiling and two side walls of the tunnel.

[0061] It should be noted that the self-moving tail 5 used in the belt conveyor in the mining system is mainly used as a device for matching and connecting the transfer machine 7 with the rear belt conveyor, and has the functions of long-distance overlap with the transfer machine 7, self-movement, height adjustment, and conveyor belt deviation adjustment. Here, the self-moving tail 5 is powered by emulsion / hydraulic oil, and its principle is to use friction and serve as fulcrums to achieve self-movement of the tail of the belt conveyor.

[0062] In this embodiment, by providing a connecting frame 4 for connecting to the self-moving tail 5 at the bottom of the frame 2, the entire anchor mechanism can be installed on the self-moving tail 5 through the connecting frame 4, so that the anchor mechanism can move with the self-moving tail 5; at the same time, by installing the anchor drilling rig 1 on the swinging mechanism 3, the anchor drilling rig 1 can be swung on the frame 2 driven by the swinging mechanism 3 to achieve the adjustment of the working position of the anchor drilling rig 1. It can be seen that after the anchor mechanism provided in the present application is connected to the self-moving tail 5 through the connecting frame 4, its anchor cable area can be increased. At the same time, through the setting of the swinging mechanism 3, its working position in the tunnel can be adjusted according to the on-site tunnel conditions to meet the requirements of tunnel anchoring.

[0063] In some possible embodiments, the swing mechanism 3 includes a mounting base 301, a swing arm 302 and a swing cylinder 303. The mounting base 301 is installed on the frame 2; the first end of the swing arm 302 is connected to the mounting base 301; the swing cylinder 303 is connected to the second end of the swing arm 302, and the swing cylinder 303 is connected to the anchor drilling rig 1. The swing cylinder 303 is used to drive the anchor drilling rig 1 to swing circumferentially so that it swings relative to the frame 2 with respect to the anchor drilling rig 1.

[0064] It should be noted that the swing mechanism 3 can also include a mounting frame 304, which is mounted on the second end of the swing arm 302, and the swing cylinder 303 can be mounted on the mounting frame 304. Here, a valve group connected to the swing cylinder 303 can also be installed on the mounting frame 304.

[0065] Here, the swing cylinder 303 can drive the anchor drill 1 to rotate circumferentially to change the relative position between the anchor drill 1 and the mounting seat 301 and the flip angle of the anchor drill 1, thereby adjusting the working position of the anchor drill 1.

[0066] Since the anchor drill 1 can be turned over by the swing cylinder 303 , the anchor drill 1 in this embodiment can perform drilling operations on the ceiling and the two side walls of the tunnel under the turning control of the swing cylinder 303 .

[0067] Furthermore, the swing arm 302 is a telescopic swing arm, which is used to drive the anchor drill rig 1 to move along the length direction of the telescopic swing arm.

[0068] Here, by selecting the swing arm 302 as a telescopic swing arm, the anchor drill 1 can be moved along the length direction of the telescopic swing arm under the extension and retraction of the telescopic swing arm to change the distance between the anchor drill 1 and the mounting seat 301, so that the anchor drill 1 can adjust the working position of the anchor drill 1 by adjusting the length of the telescopic swing arm according to the actual situation of the tunnel.

[0069] Furthermore, the telescopic swing arm includes an arm body and a first telescopic oil cylinder. The arm body is sleeved on the cylinder barrel of the first telescopic oil cylinder. The piston rod of the first telescopic oil cylinder is connected to the swing oil cylinder 303.

[0070] Here, the first end of the arm body is connected to the mounting seat 301, the first telescopic cylinder and the arm body are coaxially arranged, and the free end of the piston rod of the first telescopic cylinder is located at the second end of the arm body.

[0071] In this embodiment, by arranging the telescopic swing arm on the cylinder barrel of the first telescopic cylinder and connecting the piston rod of the first telescopic cylinder to the swing cylinder 303, it is possible to control the length of the telescopic swing arm by controlling the telescopic length of the piston rod of the first telescopic cylinder, so as to adjust the working position of the anchor drilling rig 1 by adjusting the length of the telescopic swing arm.

[0072] For further information, see Figure 1 , Figure 2 and Figure 4 A rotating frame 305 is provided on the mounting seat 301, and the first end of the swing arm 302 is hinged to the rotating frame 305; a second telescopic cylinder is provided under the swing arm 302, the cylinder barrel of the second telescopic cylinder is movably connected to the rotating frame 305, and the piston rod of the second telescopic cylinder is movably connected to the swing arm 302; the swing arm 302 can rotate up and down with the first end of the swing arm 302 as the center under the telescopic drive of the second telescopic cylinder.

[0073] Here, the second telescopic oil cylinder is located below the swing arm 302. The swing arm 302 can be lifted upwards when driven by the extension of the second telescopic oil cylinder; and can be dropped downwards when driven by the retraction of the second telescopic oil cylinder.

[0074] In this embodiment, the first section of the swing arm 302 is hinged with the rotating frame 305, and the second telescopic cylinder is used to connect the rotating frame 305 and the swing arm 302 respectively, so that the swing arm 302 can be driven by the extension and retraction of the second telescopic cylinder to realize the up and down rotation of the swing arm 302 with its first end as the center, so as to realize the adjustment of the working position of the anchor drill 1 connected to the swing arm 302, thereby facilitating the anchor drill 1 to drill anchors in all positions on the entire tunnel ceiling and both sides.

[0075] Alternatively, see Figure 1 , Figure 2 and Figure 3The rotating frame 305 includes a frame body 3051, a first rotating connection part 3052 and a second rotating connection part 3053, the frame body 3051 is connected to the mounting seat 301; the first rotating connection part 3052 is movably connected to the frame body 3051, and the first end of the swing arm 302 is hinged to the first rotating connection part 3052; the first rotating connection part 3052 can rotate relative to the frame body 3051 when the swing arm 302 rotates left and right with its first end as the center; the second rotating connection part 3053 is located below the first rotating connection part 3052 and is movably connected to the frame body 3051, and the cylinder barrel of the second telescopic cylinder is movably connected to the second rotating connection part 3053; when the second telescopic cylinder rotates left and right with the swing arm 302, the second rotating connection part 3053 can rotate relative to the frame body 3051 with the rotation of the second telescopic cylinder. Correspondingly, a third telescopic cylinder is provided on both sides of the swing arm 302, the cylinder barrel of the third telescopic cylinder is connected to the side of the swing arm 302, and the piston rod of the third telescopic cylinder is connected to the frame 3051; the swing arm 302 can rotate left and right with the first end of the swing arm 302 as the center under the telescopic movement of the two third telescopic cylinders.

[0076] Here, by movably connecting the first rotating connection part 3052 and the second rotating connection part 3053 to the frame 3051 respectively, the swing arm 302 connected to the first rotating connection part 3052 and the frame 3051 are made to be softly connected, and the second telescopic oil cylinder connected to the second rotating connection part 3053 and the frame 3051 are made to be softly connected, so that when the third telescopic oil cylinders located on both sides of the swing arm 302 are telescopically moved, the swing arm 302 and the second telescopic oil cylinder can both rotate left and right relative to the frame 3051. For example, when the piston rod of the third telescopic oil cylinder located on one side of the swing arm 302 extends in a direction away from the cylinder barrel, and the piston rod of the third telescopic oil cylinder located on the other side of the swing arm 302 retracts in a direction close to the cylinder barrel, the swing arm 302 rotates to the side of the third telescopic oil cylinder whose piston rod retracts in a direction close to the cylinder barrel under the control of the two third telescopic oil cylinders, and at the same time, the second telescopic oil cylinder is driven by the swing arm 302 and also swings synchronously with the swing arm 302.

[0077] In this embodiment, a first rotating connection part 3052 and a second rotating connection part 3053 movably connected to the frame 3051 are provided to realize that the swing arm 302 connected to the first rotating connection part 3052 can swing left and right relative to the frame 3051, and the second telescopic cylinder connected to the second rotating connection part 3053 swings left and right with the swing arm 302 relative to the frame 3051; and then the third telescopic cylinder located on both sides of the swing arm 302 is used to control the swing arm 302 to swing left and right with its first end as the center, thereby realizing the adjustment of the working position of the anchor drilling rig 1 connected to the swing arm 302 by the two third telescopic cylinders, so as to facilitate the anchor drilling rig 1 to drill anchors in all positions on the entire tunnel ceiling and both sides.

[0078] In some possible embodiments, the connecting frame 4 and the self-moving tail 5 are detachably connected.

[0079] Here, the connection mode between the connecting frame 4 and the self-moving tail 5 is selected as a detachable connection, which can improve the connection flexibility between the connecting frame 4 and the self-moving tail 5, so as to facilitate the replacement and maintenance of the connecting frame 4 by the staff.

[0080] Furthermore, a connecting plate is provided on the self-moving tail 5, and the connecting plate is arranged along the length direction of the tail frame 501 of the self-moving tail 5; the position of the connecting frame 4 can be adjusted on the connecting plate, and the connecting frame 4 is detachably connected to the connecting plate.

[0081] Here, the connecting plate is located on the side of the tail frame 501 of the self-moving tail 5, and the connecting frame 4 can be detachably installed on the connecting plate through a bolt assembly; wherein, both side portions of the self-moving tail 5 can be connected with connecting plates, and each connecting plate can be connected to the connecting frame 4 of two or more anchor rod mechanisms, so that two or more anchor rod mechanisms can be installed on both sides of the self-moving tail 5.

[0085] It should be noted that when two or more of the above-mentioned anchor rod mechanisms are installed on the tail frame 501, the operations of the two or more of the above-mentioned anchor rod mechanisms can be independent of each other, and there is no connection relationship between the two or more anchor rod mechanisms. Therefore, the self-moving tail provided in this embodiment can select the installation quantity and installation position of the anchor rod mechanism according to the row spacing of different lanes to adapt it to the needs of different lanes.

[0086] Since the self-moving tail of this embodiment includes any of the anchor rod mechanisms in the first aspect described above, it has the beneficial effects of any of the above embodiments, which will not be described in detail here.

[0092] When the mining system provided in this embodiment is performing excavation and anchoring operations, after the excavation part of the anchor drill 6 completes the staged excavation target, the anchor drill 8 is used to drill anchors at important parts of the tunnel. While ensuring the safety and stability of the tunnel, the anchor drill 6 can continue to excavate, and the anchors at the remaining positions are supplemented by the anchor mechanism provided on the tail of the self-propelled machine 5. Here, since the anchor mechanism can supplement the anchors that cannot be completed by the anchor drill 8, it is beneficial to improve the excavation and tunneling efficiency of the mining system.
