DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0027] Reference below Figures 1 to 6 , describing the shield system of the anchor and miner according to an embodiment of the present invention.

[0028] See also Figure 1 The shield system of the anchor-mining machine according to an embodiment of the present invention includes a shield mechanism 1, a slide assembly 2, a wing-spreading roof assembly 4, a temporary support 6 and a strut assembly 8.

[0029] The shield mechanism 1 includes a main frame 12, a sliding top plate 11 and a front probe 15. The sliding top plate 11 and the main frame 12 are slidably connected, and the front probe 15 is used to drive the sliding top plate 11 to move forward and backward. The slide assembly 2 is arranged between the main frame 12 and the sliding top plate 11, and the slide assembly 2 is slidably connected to the sliding top plate 11. The wing ceiling assembly 4 is arranged on both sides of the sliding top plate 11. The top end of the temporary support member 6 is connected to the left and right ends of the slide assembly 2, and the temporary support member 6 is retractable. The top end of the strut assembly 8 is connected to the left and right sides of the main frame 12.

[0030] The main frame 12 is the main support structure of the entire shield system, used to carry the slide assembly 2 and the wing-spreading ceiling assembly 4. The main frame 12 is also the installation platform for the temporary support 6 and the strut assembly 8. The sliding top plate 11 and the wing-spreading ceiling assembly 4 are connected together, and the entire body is telescopically moved by the front probe 15, thereby extending into the undeveloped area of the tunnel. The number and specific type of temporary support members 6 and front probes 15 are designed according to actual needs. The temporary support members 6 and front probes 15 can be single-stage or multi-stage telescopic mechanisms, and there is no specific limitation on this. For example, the number of front probes 15 is one, and the number of temporary support members 6 is two. The temporary support members 6 and front probes 15 are single-stage cylinders, which can achieve precise position control and meet high load requirements. The slide assembly 2 realizes the expansion of the support range in the front-to-back direction. The slide assembly 2 enables the sliding top plate 11 and the wing-spreading ceiling assembly 4 to move in the front-to-back direction without offset. The wing-spreading ceiling assembly 4 is used to achieve the expansion of the support range in the left-to-right direction.

[0031] It can be seen that the temporary support 6 supports the slide assembly 2, and the strut assembly 8 supports the main frame 12, which can distribute the load from the sliding top plate 11 and the slide assembly 2 more evenly on the temporary support 6, ensuring that the force point of the temporary support 6 is better and avoiding local overload.

[0032] The shield system of the embodiment of the present invention needs to be installed on the anchor and digging machine when in use. The installation method is as follows: the bottom end of the temporary support 6 is connected to the chassis of the anchor and digging machine, the bottom end of the strut assembly 8 is connected to the frame of the anchor and digging machine, and the rear end of the shield mechanism 1 is connected to the frame of the anchor and digging machine. In the initial state of the shield system of the embodiment of the present invention, the slide assembly 2 and the sliding top plate 11 are fully retracted. When the shield system is in the supporting state, the front probe 15 is fully extended, the sliding stroke of the slide assembly 2 is S1, and the sliding stroke of the sliding top plate 11 relative to the slide assembly 2 is S2. Then, the sliding stroke of the sliding top plate is S, S=S1+S2.

[0033] According to the shield system of the anchor-drilling machine according to the embodiment of the present invention, a retractable sliding roof and wing-spreading roof assembly are provided. The shield system can be equipped on the anchor-drilling machine. The sliding roof and wing-spreading roof assembly can be extended into the unsupported empty roof area in front of the excavation working face in advance to form a temporary protective barrier, thereby realizing zero-empty roof distance advance support operation at the head of excavation, improving the adaptability and reliability of underground excavation operations to roof control, and ensuring the safe, stable and efficient operation of the excavation operation.

[0034] Combine Figure 1 and Figure 2 As shown, in some embodiments, the shield mechanism 1 further includes a support arm 13, a screw adjustment mechanism 14, and a first pin 16. The front end of the support arm 13 is fixedly connected to the main frame 12 via multiple first pins 16. The screw adjustment mechanism 14 is located at the end of the support arm 13. The number and installation position of the first pins 16 are selected according to actual needs. The screw adjustment mechanism 14 is equipped with a screw 141. By rotating the screw 141, its working length can be adjusted, thereby changing the height and angle of the main frame 12, so that the shield mechanism 1 better fits the tunnel roof.

[0035] The main frame 12 includes a box beam structure and side arms 124. The side arms 124 are located on both sides of the rear of the box beam structure. Sliding grooves 123 are provided on the side walls of the box beam structure. A first mounting seat 121 is provided at the bottom of the rear side of the main frame 12. Second mounting seats 122 are provided on both sides of the middle portion of the main frame 12. The first mounting seat 121 is connected to the rear end of the front probe 15, and the second mounting seat 122 is connected to the top end of the strut assembly 8. In one example, the cross-section of the box beam structure is rectangular, compact, and has high space utilization.

[0036] Tracks 111 are provided on both sides of the rear of the sliding top plate 11. A special-shaped plate with a higher center and lower sides is provided at the front end of the sliding top plate 11. Tracks 111 are slidably connected to the box girder structure. Long grooves 113 are provided on the sidewalls of track 111. A third mounting seat 112 is provided at the bottom of the special-shaped plate, which is connected to the front end of the front probe 15. Roof interfaces 114 are provided at the bottom of each end of the special-shaped plate. These interfaces 114 can be connected to the wing-spreading ceiling assembly 4 via ball joints. A portion of track 111 is embedded within the main frame 12, improving guidance accuracy and reducing the risk of deformation.

[0037] Displacement sensors are provided in the temporary support 6 and the front probe 15 to detect the extended length of their respective push rods, thereby matching the front probe depth with different mining heights. The front probe depth can be adjusted through the program to correspond to the mining height parameters, and different mining heights can set different front probe depths.

[0038] Combine Figures 1 to 5As shown, in some embodiments, the carriage assembly 2 includes a frame 21, two connecting rods 24, a slider shaft 25, a second pin 26, and two sliding blocks 27. The sidewalls of the frame 21 are rotatably connected to the connecting rods 24 via the second pin 26 to achieve a certain degree of swinging freedom. The slider shaft 25 is connected to the two connecting rods 24, and the sliding block 27 is connected to the connecting rods 24 and separated from the connecting rods 24. The slider shaft 25 passes through the elongated slot 113 and the sliding slot 123. The sliding block 27 is located inside the elongated slot 113, and the connecting rods 24 are located outside the sliding slot 123. When the shield system is in operation, the front probe 15 drives the sliding top plate 11, which drives the sliding block through the sliding slot. The sliding block drives the connecting rod, achieving the forward or backward movement of the carriage assembly.

[0039] The structural design of the slide assembly 2 not only ensures the stability of the sliding top plate 11 during movement, but also improves flexibility through the rotational connection between the connecting rod 24 and the frame 21, and is suitable for the needs of anchor drilling operations under complex tunnel conditions.

[0040] like Figure 5 As shown, fourth mounting bases 22 are provided at both ends of the frame 21, and the fourth mounting bases 22 are connected to the top of the temporary support member 6. The frame 21 is also provided with a net hanging block 23 for hanging the anchor net. The specific type of the net hanging block 23 is set according to actual needs and is not limited thereto. For example, the net hanging block 23 contains a magnetic member to easily attract the anchor net, thereby adsorbing and fixing the anchor net mesh.

[0041] like Figure 1 As shown, the support rod assembly 8 includes a sleeve 81, a support rod 82, and a latch 83. The support rod 82 is disposed in the sleeve 81. The sleeve 81 is provided with a plurality of insertion holes at intervals. The top end of the sleeve 81 is provided with a connecting hole 84, which is connected to the second mounting base 122. By plugging the latch 83 into the connecting hole 84 at different positions, the extension length of the support rod 82 can be adjusted.

[0042] like Figure 6 As shown, in some embodiments, the wing-spreading ceiling assembly 4 includes an adaptive roof panel 41, an anchor mesh support 42, a mesh fixing block 43, a mounting plate 44, a curved guard plate 45, and a dust curtain 46. The curved guard plate 45 is located at the front end of the adaptive roof panel 41, which is located above both sides of the special-shaped plate. The anchor mesh support 42 is connected to the rear end of the adaptive roof panel 41, and the anchor mesh support 42 has a hollowed-out center. The mesh fixing block 43 is located on the anchor mesh support 42, the mounting plate 44 is located at the bottom of the adaptive roof panel 41, and the dust curtain 46 is connected to the mounting plate 44. When the shield system is in operation, the adaptive roof panel 41 maintains uniform contact with the top coal and rock layer of the tunneling roadway. The adaptive roof panel 41 provides evenly distributed support for the roof, and can automatically adjust its state according to environmental conditions.

[0043] Combine Figure 1 and Figure 2 As shown, the wing-spreading canopy assembly 4 also includes a net storage assembly 3 and a net restraining assembly 7. These are positioned, from front to back, above the shield mechanism 1 to store and hang the anchor net. In one example, the net storage assembly 3 and the net restraining assembly 7 are vertical rods that are detachably mounted on the shield mechanism 1.

[0044] The shield system for the anchor miner also includes a dust collector interface 5, a dust collector 51, a transition frame 52, and an air duct 53. The dust collector interface 5 is located on the main frame 12 and is used to mount the dust collector 51. The air duct 53 and transition frame 52 are arranged in sequence at the bottom of the main frame 12 from front to back to collect headwind. The specific type of dust collector 51 is not limited.

[0045] The shield system of the anchoring and mining machine of the embodiment of the present invention is generally integrated into the whole system of the anchoring and mining machine adapted to the operation with smaller empty top distance. When the mining height is determined, the screw adjustment mechanism and the strut assembly at the rear of the shield system are adjusted. Then the shield system coordinates with the cutting system to complete the cutting operation; secondly, the shield system cooperates with the anchor drilling system to complete the anchoring operation. During the anchoring operation process, the empty top distance can be reduced to zero through the pre-set two-stage forward probe telescopic mechanism. Since there is a certain correspondence between the effective length of the screw, the telescopic length of the forward probe and the mining height of the tunnel, when the mining height changes, it is necessary to adjust the screw and the forward probe extension.

[0046] The shield system for the anchor miner according to the above-mentioned embodiment of the invention has the following beneficial effects: 1. The above embodiment can be equipped on a drilling and anchoring equipment, especially an integrated drilling and anchoring machine, to perform advance support on the head of the excavation working face, thereby realizing zero-clearance advance support operation on the head of the excavation working face.

[0047] 2. The shield system of the above-mentioned embodiment of the invention has a screw adjustment and a two-stage forward adjustment mechanism, which can adapt to different mining heights and operations under abnormal conditions. It improves the adaptability of the drilling and anchoring equipment to different mining heights and different roof conditions, and the equipment has a wide range of adaptability.

[0048] 3. The shield system of the above-mentioned embodiment of the invention has a built-in displacement sensor, which can detect and control the extension of the forward probe in real time, thereby improving the degree of automation of the support system.

[0049] 4. The shield system of the embodiment of the invention has a mesh fixing plate provided on the wing-shaped ceiling, which can absorb the mesh and has strong functionality.

[0050] 5. The shield system of the above-mentioned invention embodiment adopts the telescopic mechanism of the slide assembly to realize the sliding stroke S of the sliding top plate. The sliding stroke of the slide assembly is S1, and S>S1; that is, it ensures that the force point of the supporting drive member is better, and only one actuator is used to achieve advanced support for the head.

[0051] 6. The shield mechanism of the above-mentioned embodiment of the invention is provided with interfaces for multiple dust removal modes, which can integrate multiple dust removal modes and has high dust collection adaptability. In combination with other auxiliary mist reduction mechanisms, the amount of dust encountered can be greatly reduced.

[0052] 7.
