Description

Technical Field

[0001] This invention relates to the technical field of rapid tunneling and intelligent support equipment for coal mine roadways, and in particular to an integrated tunneling and anchoring machine. Background Technology

[0002] Currently, integrated tunnel boring and anchoring machines are widely used in coal mine roadway excavation to achieve integrated operations of cutting, loading, transportation, and anchoring. However, roof and sidewall mesh laying is still mainly done manually, with low automation and poor process coordination. This has become a core bottleneck restricting rapid and intelligent tunneling, and the main problems are as follows: (1) The method of laying the net is outdated and the safety risks are high. Traditional net laying relies on manual handling, lifting and splicing of metal mesh. Workers need to work in close proximity in open roof areas and narrow side areas, facing safety hazards such as broken side, falling rocks and falling from heights. The quality of manual splicing and connection is unstable, and it is easy to have insufficient mesh splicing and insecure fixation, which affects the reliability of the support.

[0003] (2) The roof and side mesh laying are separated, resulting in low efficiency. Most existing tunneling and anchoring machines are only equipped with simple roof mesh laying mechanisms, and there are basically no automated mesh laying devices for the side. Roof and side mesh laying need to be done in separate sequences and by separate personnel, resulting in long downtime and waiting time, which directly affects the efficiency of tunneling and support.

[0004] (3) Poor integration and insufficient spatial adaptability of the net laying device. Most of the publicly available automatic net laying schemes are single top plate net roll and net laying mechanisms, installed on the front exploration beam or temporary support. They are simple in structure and single in function, and do not take into account the net laying needs of both sides. Some devices interfere with the cutting section, temporary support and drilling frame, occupy a lot of space, are not very applicable, and cannot adapt to the continuous laying characteristics of lightweight high-strength fiber net.

[0005] (4) The application of fiber mesh is not compatible with automated equipment. Fiber mesh is lightweight, tough, corrosion resistant and easy to roll and continuously lay, and is gradually replacing traditional metal mesh. However, the existing tunneling and anchoring machines lack a dedicated automatic laying, flattening, positioning and tensioning mechanism for fiber mesh in the top and side areas. Manual assistance is still required for unfolding and fixing, which fails to give full play to the high efficiency and safety advantages of fiber mesh. Summary of the Invention

[0019] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of this application, it should be noted that the terms "inner", "outer", "left", "right", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] In the description of this application, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” shall be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components.

[0022] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0023] Example Reference Figures 1-15 This invention provides a tunneling and anchoring integrated machine, including a tunneling and anchoring integrated machine body, and an automatic side-laying net device 1 respectively arranged on both sides of the tunneling and anchoring integrated machine body in the forward direction; the automatic side-laying net device 1 includes an extension platform 12 and a first net roll assembly 18, the lower end surface of the extension platform 12 is provided with a guide rail assembly 11, and the guide rail assembly 11 is used to connect with the tunneling and anchoring integrated machine body; an extension drive assembly is provided on the tunneling and anchoring integrated machine body, and one end of the extension drive assembly is connected to the extension platform 12, enabling the extension platform 12 to reciprocate along a first direction; a rotary reducer 14 is provided on the extension platform 12, a lifting mechanism 15 is provided on the rotary reducer 14, a swing frame 16 is provided on the lifting mechanism 15, and the first net roll assembly 18 is arranged on the swing frame 16; a first pressing assembly 17 is provided on the swing frame 16, the first pressing assembly 17 is used to abut against the fiber net roll on the first net roll assembly 18 and maintain the fiber net roll with a pressing force.

[0024] In some embodiments, the tunneling and anchoring machine mainly consists of an automatic side net laying device 1, an automatic top net laying device 2, a top anchor bolting machine assembly 3, a side anchor bolting machine assembly 4, a cutting device 5, a loading device 6, a scraper conveyor 7, a chassis 8, a hydraulic system 9, and an electrical system 10.

[0025] An automatic top net laying device 2 is installed at the upper end of the main body of the tunneling and anchoring machine. The automatic top net laying device 2 is set on two automatic side net laying devices 1. The automatic top net laying device 2 and the automatic side net laying device 1 lay the net synchronously during the movement of the equipment. The side anchor bolt assembly 4 and the top anchor bolt assembly 3 provide synchronous support and fixation, so as to realize automatic continuous net laying.

[0026] One end of the extension drive component of the automatic paving net device 1 is set on the main body of the tunneling and anchoring machine. The extension drive component is used to move the extension platform outward. The front of the extension platform 12 is provided with the mounting flange interface of the top anchor bolt assembly 3, and the middle position is provided with a sinking platform for installing the rotary reducer 14, thereby reducing the overall installation height of the automatic paving net device 1.

[0027] The guide rail assembly 11 is the slide of the extension platform 12, which allows the automatic side netting device 1 to extend to both sides of the main body of the tunneling and anchoring machine. The extension stroke is not less than 600mm. The automatic side netting device 1 is retracted when the equipment is moving or when personnel are passing by on the side, and it is extended when the equipment stops laying the side netting. This can increase the working space for personnel and also hold the side netting against the side, which helps the anchor netting to be flat.

[0028] The extension platform 12 is the mounting base for the automatic siding netting device 1. It can slide left and right on the guide rail assembly 11 to meet the positioning requirements of personnel supporting the anchor bolts.

[0029] A personnel platform component 13 is installed on the extended platform. This component comprises a top anchor operating platform, a side anchor operating platform, and a transition platform. The personnel platform component 13 is integrally screwed onto the extended platform 12 and can slide outwards, satisfying both the operational needs of personnel and the external sliding support requirements of the top anchor bolting machine, without affecting the machine's width. The top anchor operating platform provides the operating range for the top anchor bolting machine operators, the side anchor operating platform provides the operating range for the side anchor bolting machine operators, and the transition platform serves as a connecting passage between the top and side anchor operating platforms, ensuring both the minimum height of the side anchor bolting machine support position and the continuity of the personnel movement platform.

[0030] The rotary reducer 14 enables the lifting mechanism 15 to swing within a certain range, generally controlling the lifting mechanism 15 to swing within a 90° range. The rotary reducer is the rotating power component of the automatic net laying device. The first roll of net assembly 18 can swing from the inside to the outside, or from the outside to the inside. Swinging to the inside reduces the width of the entire machine, facilitating equipment movement and pedestrian passage. Swinging to the outside tightens the fiber net, which is beneficial for automated fiber net laying and flattening it against the roadway side.

[0031] A swing frame 16 is provided on the lifting mechanism 15. The lifting mechanism 15 can raise and lower the swing frame 16, that is, adjust the height of the swing frame 16; the lifting stroke is not less than 700mm. When the equipment is moving, the lifting mechanism 15 can lower the first roll of netting assembly 18 below the set height of the machine body; during automated netting laying, the lifting mechanism 15 lifts the first roll of netting assembly 18 to the top of the roadway, realizing the laying of fiber netting from top to bottom on the roadway sidewall.

[0032] The first roll net assembly 18 is mounted on the swing frame 16. The first roll net assembly 18 can achieve multi-dimensional adaptive adjustment such as swing and height adjustment.

[0033] The first roll assembly 18 is used to hold the fiber web roll. During the unwinding process, the first pressing assembly 17 abuts against the fiber web roll, so that the fiber web roll maintains a pressing force during the unwinding process, and the fiber web can maintain a certain tension.

[0034] The auxiliary components 19 arranged to ensure the functional integrity of the integrated drilling and anchoring machine mainly include an extended displacement sensor 191, an auxiliary multi-way valve 192, a handheld remote controller 193, and a grouting box 194. The extended displacement sensor 191 is used to monitor the slippage data of the extended platform 12, the auxiliary multi-way valve 192 is the control and debugging unit for the automatic mesh laying action, the handheld remote controller 193 is the remote control unit for the automatic mesh laying action, and the grouting box 194 is the grouting unit of the integrated drilling and anchoring machine.

[0035] This integrated tunneling and anchoring machine achieves automatic and integrated laying of top and side netting. It integrates two independent netting systems on a single machine, with a reasonable structural layout and no interference between their operations. It overturns the traditional single netting laying and multi-equipment operation mode, and can match tunneling and anchoring construction simultaneously, effectively improving the automation level of roadway support and overall construction efficiency.

[0036] The automatic sidewall netting device 1 adopts a multi-dimensional adaptive structure with telescopic, lifting, rotating, and tilting functions, which can flexibly adjust its state according to different working conditions such as equipment movement, personnel passage, and netting operation. It can reduce the size of the equipment body, ensure passage safety, and adapt to complex roadway conditions and equipment tilting, ensuring that the sidewall netting is laid flat, standardized, and has a good fit.

[0037] The automatic netting laying device 1 adopts an integrated structure of hydraulic pre-tensioning and active drive netting release. The first clamping component 17 continuously pre-tensions the net roll to prevent loosening and deviation, and the first rotary motor 175 enables controllable winding and unwinding of the net roll. The entire process is automated, requiring no manual intervention, and the netting tension is uniform, ensuring stable quality of netting construction.

[0038] Reference Figure 3 and Figure 4In an optional embodiment, the lifting mechanism 15 includes an inner sleeve 151, an outer sleeve 153, and a lifting cylinder 152; the lifting cylinder 152 is disposed inside the inner sleeve 151, the outer sleeve 153 is sleeved on the inner sleeve 151, and the movable end of the lifting cylinder 152 extends out of the inner sleeve 151 and is connected to the outer sleeve 153. An oscillating cylinder 154 is provided on the outer sleeve 153. One end of the oscillating cylinder 154 is used to connect to the outer sleeve 153, and the other end is used to connect to the oscillating frame 16.

[0039] In some embodiments, the lifting cylinder 152 of the lifting mechanism 15 enables the outer sleeve 153 to be raised and lowered relative to the inner sleeve 151. The lifting mechanism 15 saves space and can effectively resist the lateral forces generated during net laying at any rotation angle. The sliding stroke of the lifting cylinder 152 is not less than 600mm. In the walking state, the lifting mechanism 15 can be lowered to the lowest position to ensure that it does not affect the walking. In the net laying state, the lifting mechanism 15 can be raised to the highest position to ensure that the fiber net is laid along the roof of the tunnel.

[0040] The sway cylinder 154 is hinged at one end to the outer sleeve 153 of the lifting mechanism 15 via a pin, and at the other end to the swing frame 16, which can control the up and down swing of the swing frame 16 and the first clamping assembly 17.

[0041] Reference Figure 7 In an optional embodiment, the first pressing assembly 17 includes a swing seat 171, and a first swing pin 173 is provided at one end of the swing seat 171; the first swing pin 173 is used to connect with a first hinge seat 155 on the outer sleeve 153. A telescopic seat 172 is provided on the swing seat 171, and a first telescopic cylinder 174 is provided between the swing seat 171 and the telescopic seat 172; a first mounting bracket 177 is provided at both the upper and lower ends of the telescopic seat 172, a first rotary motor 175 is provided on the first mounting bracket 177, and a first mesh-deflecting sprocket 176 is assembled at the movable end of the first rotary motor 175, the first mesh-deflecting sprocket 176 is used to abut against the fiber web roll.

[0042] Reference Figure 5 and Figure 6 In an optional embodiment, the swing frame 16 includes an upper support frame 161 and a lower support frame 162; the upper end of the swing seat 171 is provided with the upper support frame 161, and the lower end of the swing seat 171 is provided with the lower support frame 162; a cylinder lug seat 163 is provided on the upper support frame 161, and one end of the sway cylinder 154 is connected to the cylinder lug seat 163; An upper clamping mechanism 164 is provided at one end of the upper support frame 161 away from the swing seat 171, and a lower clamping mechanism 165 is provided at one end of the lower support frame 162 away from the swing seat 171. The upper clamping mechanism 164 is provided with a movable buckle and a pin hole; the lower clamping mechanism 165 is provided with a small tray 1651, and two positioning protrusions 1652 are provided on the small tray 1651. The lower end of the small tray 1651 has a lower flange 1655, which is rotatably mounted on the lower clamping mechanism 165 via a thrust ball bearing 1653. A limiting plate 1654 is provided on the lower flange 1655 to prevent the lower flange 1655 from disengaging from the lower clamping mechanism 165.

[0043] In some embodiments, the swing seat 171 of the first clamping assembly 17 is connected to the first hinge seat 155 of the outer sleeve 153 via the first swing pin 173; the upper support frame 161 and the lower support frame 162 of the swing frame 16 are bolted to the upper and lower ends of the swing seat 171; an upper clamping mechanism 164 is bolted to the upper support frame 161, and a lower clamping mechanism 165 is bolted to the lower support frame 162.

[0044] A telescopic seat 172 is provided on the swing seat 171, and the movable end of the first telescopic cylinder 174 is connected to the telescopic seat 172; two first mounting brackets 177 are provided on the telescopic seat 172, and a first rotary motor 175 is fixed on the first mounting bracket 177. The first rotary motor 175 can make the first net pulling sprocket rotate. The telescopic seat 172 and the swing seat 171 are installed by a sliding groove. Through the action of the first telescopic cylinder 174, the telescopic seat 172 can extend and retract. The stroke must be at least greater than the radius of the fiber web roll to ensure that the first sprocket 176 can always maintain a certain pressure on the fiber web roll as it is gradually released and its diameter decreases.

[0045] The first sprocket 176 is locked to the first rotary motor 175 by axial and radial positioning, and can rotate under the action of the first rotary motor 175. Its pitch circle diameter is in a fixed ratio with the diameter of the fiber web roll, and this ratio can be adjusted according to the web winding speed and the speed of the first rotary motor 175. The first pressing assembly 17 has a centrally symmetrical arrangement of the first sprocket 176, the first rotary motor 175 and the first mounting bracket 177, which is beneficial to the first sprocket 176 pressing the fiber web roll symmetrically from top to bottom and from side to side, and the force is more even.

[0046] One end of the sway cylinder 154 is connected to the cylinder lug 163. The sway cylinder causes the swing frame 16 to tilt up and down or left and right. This is used to adjust the laying angle of the first roll net assembly 18 when the equipment is tilted left and right or forward and backward, so as to ensure that the laying direction is always along the direction of the roadway.

[0047] Reference Figure 8 In an optional embodiment, the first wire mesh assembly 18 includes a first wire mesh shaft 181, with first edge guide wheels 183 provided at both ends of the first wire mesh shaft 181, and the first edge guide wheels 183 extending from both ends of the first wire mesh shaft 181; a first positioning hole 184 matching the positioning protrusion 1652 is provided on the first edge guide wheel 183; and a plurality of first straight hooks 182 are provided on the first wire mesh shaft 181.

[0048] Both ends of the first roll of the fiber web assembly 18 protrude from the first edge wheel 183. The middle of the first roll of the fiber web assembly 181 is welded with evenly arranged first straight hooks 182 for fixing the starting end of the fiber web. Two first edge wheels 183 are welded on both sides for supporting the fiber web roll. The two ends of the first roll of the fiber web assembly 181 are respectively inserted into the upper clamping mechanism 164 and the lower clamping mechanism 165. The movable buckle and the pin hole of the upper clamping mechanism 164 cooperate to enable the first roll of the fiber web assembly 18 to be quickly connected and separated from the upper clamping mechanism 164.

[0049] A rotating hole is provided on the small tray 1651 of the lower clamping mechanism 165, and one end of the first roll spool 181 is inserted into the rotating hole of the small tray 1651. The first positioning hole 184 on the first side guard wheel 183 matches the positioning protrusion 1652 on the small tray 1651, so that the first side guard wheel 183 and the small tray 1651 rotate synchronously. The lower flange 1655 of the small tray 1651 is mounted on the lower clamping mechanism 165, and a thrust ball bearing 1653 is mounted on the lower flange 1655, so that the small tray 1651 rotates smoothly on the lower clamping structure.

[0051] The automatic roof netting device 2 is equipped with an adaptive fitting structure and a deviation adjustment mechanism, which can adapt to uneven roadway roofs. It can also automatically correct the netting direction based on equipment deviation during tunneling, ensuring the netting trajectory is precisely aligned with the roadway tunneling direction. The device adopts an anti-interference structural design, effectively avoiding conflicts during machine operation, resulting in enhanced operational safety and adaptability.

[0052] Both the automatic side net laying device 1 and the automatic top net laying device 2 have a large-capacity net storage design to meet the needs of continuous operation in a single shift; and both are equipped with an independent and dedicated net storage and rolling mechanism. The top net and side net are respectively adapted to high-strength fiber nets of different specifications. The net storage capacity is sufficient to meet the needs of continuous net laying operations in a single production shift in the well, greatly reducing the frequency of net replacement and improving the continuous operation capability and construction efficiency of the equipment.

[0053] Reference Figure 11 , Figure 12 and Figure 13 In an optional embodiment, one of the mounting net bags 232 is provided with a mounting retaining ring 235, and a rolling bearing 234 is provided inside the mounting retaining ring 235; the other mounting net bag 232 is provided with a movable cover plate 236, and the movable cover plate 236 fixes the rolling bearing 234 on the mounting net bag 232. Reference Figure 14 The second web assembly 24 includes a second web shaft 241, and a second edge wheel 243 is provided at each end of the second web shaft 241, with the second edge wheel 243 extending from both ends of the second web shaft 241. A plurality of second straight hooks 242 are provided on the second roll shaft 241, and both ends of the second roll shaft 241 are respectively assembled in a rolling bearing 234.

[0054] Referring to 15, in an optional embodiment, a second clamping assembly 25 is also included, the second clamping assembly 25 including a second telescopic cylinder 255, a telescopic plate 233, a second mounting bracket 252, and a second rotary motor 253; A telescopic frame 251 is provided at the lower end of the mounting connecting plate, and the telescopic plate 233 is slidably mounted on the telescopic frame 251. One end of the second telescopic cylinder 255 is hinged to the telescopic frame 251, and the other end is connected to the telescopic plate 233. A second mounting bracket 252 is provided on the telescopic plate 233, and the second rotary motor 253 is mounted on the second mounting bracket 252. A second mesh-deflecting sprocket 254 is assembled at the movable end of the second rotary motor 253, and the second mesh-deflecting sprocket 254 is used to abut against the fiber web roll. Reference Figure 10 In an optional embodiment, a front drive plate is provided on the front support plate 211, a mounting ball head 215 is provided on the front drive plate, and a floating ear seat 22 is provided on the mounting ball head 215. An adjustment lug 214 is provided on the lower end face of the front drive plate, and an adjustment cylinder 26 is provided on the adjustment lug 214. The movable end of the adjustment cylinder 26 is connected to the main stiffener plate 231. A drive ear 213 is also provided on the lower end face of the front drive plate, and the drive ear 213 is used to connect with the front drive assembly.

[0055] The front connecting body 21 is the mounting base of the automatic roof netting device 2. A front support plate 211 is provided on the front connecting body 21, and a central base 212 is provided on the front support plate 211. The central hole of the main stiffening plate 231 of the netting storage mechanism 23 is connected to the central base 212. The main stiffening plate 231 can swing within a small range to ensure that the netting direction can still be adjusted along the edge of the roadway roof when the tunneling and anchoring machine tilts left and right in the roadway.

[0056] The front support plate 211 has a concave design, which can meet the installation space requirements of the net storage mechanism 23 without affecting the vertical tilting of the cutting boom of the integrated tunneling and anchoring machine. The central base 212 is the swing center of the net storage mechanism 23.

[0057] A front drive plate is provided on the front support plate 211. Two adjustment lugs 214 are provided on the front drive plate. Two adjustment cylinders 26 are connected to the main stiffening plate 231, which can make the main stiffening plate 231 swing within a small range. The adjustment cylinders 26 are used to adjust the forward and backward tilt of the mesh storage device. When the equipment deviates from the center line of the roadway and moves and excavates, the mesh laying direction can also be adjusted accordingly.

[0058] A drive lug 213 is provided on the front drive plate. The front drive assembly is located on the main body of the tunneling and anchoring machine. The front drive assembly raises and lowers the front drive plate, thereby realizing the height adjustment of the automatic roof netting device 2, so that the top fiber netting fits the roof plate better.

[0059] The floating lug 22 is fixed on the mounting ball head 215. When the floating lug 22 is in contact with the roadway roof, it can self-adjust and level itself, thereby pressing the roof fiber mesh tightly onto the roof.

[0060] The mounting net 232 is an auxiliary support mechanism for the fiber web roll, and its inner diameter is larger than the diameter of the fiber web roll. A mounting net 232 is provided at both ends of the mounting connecting plate. The mounting net 232 is provided with a mounting interface for connecting with the second web roll assembly 24. One side is fixed by a rolling bearing 234 and a mounting retaining ring 235, which is generally not disassembled. The other side is fixed by a rolling bearing 234 and a movable cover plate 236, which is frequently disassembled for quick replacement of the second web roll assembly 24.

[0061] The first clamping assembly 17 and the second clamping assembly 25 function similarly. The second telescopic cylinder 255 of the second clamping assembly 25 enables the second rotary motor 253 to clamp the fiber web roll, providing initial preload to prevent the web roll from loosening. At the same time, the second rotary motor 253 drives the second sprocket 254 to rotate the web roll forward and backward, thereby realizing the unwinding and rewinding of the web.

[0062] The first roll assembly 18 and the second roll assembly 24 are storage compartments for fiber web rolls. The fiber web is rolled on the roll shaft. The maximum diameter of the roll that can be stored at one time is 300mm, and the length of the fiber web with specification 200KN / m is 20m, which can meet the continuous laying needs of a production shift.

[0063] The lifting mechanism 15 of the automatic siding netting device 1 of the tunneling and anchoring integrated machine provided by the present invention can adjust the height of the swing frame 16, and the rotary reducer 14 can make the swing frame 16 rotate, thereby continuously pre-tightening the fiber netting roll to prevent loosening and deviation; and in conjunction with the first pressing component 17, the fiber netting roll can be controlled to be wound and unwound, thereby achieving automation without manual intervention, with uniform netting tension, which can stably ensure the quality of netting construction.

[0064] The automatic sidewall mesh laying device 1 is the first to adopt the design concept of "active mesh laying". Compared with the previous "passive mesh laying" solution where the fiber mesh roll is directly placed into the mesh bag on the side of the tunneling and anchoring machine and unfolds as the machine moves, this technical solution can effectively control the state of the fiber mesh roll. When the machine starts moving, the automatic sidewall mesh laying device 1 begins to actively lay the mesh, and the laying speed is slightly greater than the moving speed. After the mesh roll is unfolded, the tension of the unfolded fiber mesh and its flatness with the roadway sidewall can be achieved through multi-degree-of-freedom movements, solving the problems of uncontrollable fiber mesh laying direction, automatic slack, automatic spread-out, and inability to flatten in previous sidewall mesh laying devices.

[0065] The automatic sidewall mesh laying device 1 is highly integrated with the walkway platform. After integration, the automatic sidewall mesh laying device does not affect the overall machine's tunneling, support, and transportation functions, nor does it affect the operating space for the anchor bolting machine operators. Compared to the previous integrated tunneling and anchoring machine walkway platform where operators of the top and sidewall anchor bolting machines had to manually lay the mesh and drill, this technical solution significantly reduces the labor intensity of operators and improves work efficiency through automatic mesh laying.

[0066] An automatic web-laying device is designed with fiber web as its core. Fiber web has the characteristics of being lightweight, flexible, and strong in tensile strength, which can realize continuous web laying, reduce the number of interconnection links, and improve efficiency.

[0067] The automatic top netting device 2, similar to the automatic side netting device 1, also adopts the design concept of "active netting release". It is highly integrated with the temporary support, which not only does not affect the up and down movement of the cutting boom, but also ensures the length of netting stored at one time, meeting the single-shift advance requirements.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
