[0034] Embodiments of the present disclosure are described in detail below, examples of which 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 only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the embodiment of the present disclosure proposes a mobile face drilling system, including: a platform 2, a plurality of drilling devices 1 and at least one walking device 3, the platform 2 is provided with an arch frame 21 arranged along the circumference of the face 5, the plurality of drilling devices 1 are distributed at intervals along the circumference of the face 5, and the drilling device 1 includes: a lifting mechanism 11, a telescopic mechanism 12 and a drilling equipment 15, the lifting mechanism 11 is arranged on the arch frame 21, and the lifting end of the lifting mechanism 11 is used for radial movement along the face 5, the telescopic mechanism 12 is arranged at the lifting end of the lifting mechanism 11, and the telescopic end of the telescopic mechanism 12 is used for moving along the vertical direction of the face 5, the drilling equipment 15 is arranged at the telescopic end of the telescopic mechanism 12, and the drilling equipment 15 is used for drilling holes in the face 5, and the walking device 3 is arranged at the bottom of the platform 2, and the walking device 3 is used for walking of the platform 2.

[0036] It can be understood that since the platform 2 is provided with an arch 21 arranged along the circumference of the face 5, and the walking device 3 is arranged at the bottom of the platform 2, multiple drilling devices 1 are distributed at intervals along the circumference of the face 5, so that the platform 2 can use the walking device 3 to walk to the face 5, and use the drilling equipment 15 of multiple drilling devices 1 to achieve synchronous drilling at multiple positions around the face 5, so that continuous grooves can be quickly excavated and an empty surface can be formed, which is convenient for realizing the crushing excavation of the face 5. Therefore, the synchronous drilling of the drilling equipment 15 in multiple drilling devices 1 effectively improves the excavation efficiency of the face 5. At the same time, compared with large mechanical equipment, the multiple small drilling equipment 15 arranged on the arch 21 has higher excavation accuracy, thereby reducing the occurrence of over-excavation, under-excavation and other problems, ensuring the flatness of the excavation section, and avoiding the shortcomings of high noise and heavy dust.

[0037] Among them, since the lifting mechanism 11 is arranged on the arch frame 21, and the telescopic mechanism 12 is arranged at the lifting end of the lifting mechanism 11, and the drilling equipment 15 is arranged at the telescopic end of the telescopic mechanism 12, the drilling equipment 15 can use the lifting mechanism 11 to move along the radial direction of the tunnel face 5, and use the telescopic mechanism 12 to move along the vertical direction of the tunnel face 5. Therefore, by using the cooperation of the lifting mechanism 11 and the telescopic mechanism 12, the position of the drilling equipment 15 can be flexibly adjusted to adapt to the drilling requirements at different positions of the tunnel face 5, thereby realizing high-efficiency and high-precision excavation operations of the tunnel face 5.

[0038] It should be noted that the platform 2 is used to support the arch frame 21 and multiple drilling devices 1 on the arch frame 21, and at the same time, auxiliary functions such as walking are realized by using components such as the walking device 3. The specific type of the platform 2 can be set according to actual needs and is not limited to this. For example, the platform 2 can be composed of multiple first longitudinal beams, multiple cross beams and multiple vertical beams. The first longitudinal beams are arranged along the length direction of the tunnel, that is, the vertical direction of the heading 5, the cross beams are arranged along the width direction of the tunnel, that is, the width direction of the heading 5, and the vertical beams are arranged along the height direction of the tunnel, that is, the height direction of the heading 5. Multiple first longitudinal beams, multiple cross beams and multiple vertical beams are connected to each other to form a frame support structure that is close to an inverted U shape.

[0039] The arch frame 21 is used to carry multiple drilling devices 1. The specific type of the arch frame 21 can be set according to actual needs and is not limited to this. For example, the arch frame 21 can be composed of two arc beams and multiple second longitudinal beams. The arc beams are arranged along the circumference of the tunnel, that is, the circumference of the tunnel face 5, and the second longitudinal beams are arranged along the vertical direction of the tunnel face 5, and multiple second longitudinal beams are arranged between the two arc beams. The two arc beams and the multiple second longitudinal beams form an arc frame support structure with an opening facing downward.

[0040] The walking device 3 is used for the walking of the platform 2, so as to facilitate the transfer of the platform 2, for example, to be arranged away from the tunnel face 5, arranged close to the tunnel face 5, moved out of the tunnel, moved into the tunnel, etc. The specific type of the walking device 3 can be set according to actual needs and is not limited to this. The number of the walking devices 3 can be two, three, four, five, etc.

[0041] The drilling device 1 is used for drilling holes in the tunnel face 5 , and the number of the drilling devices 1 may be two, three, four, five, six, seven, eight, etc.

[0042] Among them, the lifting end of the lifting mechanism 11 is used to move along the radial direction of the face 5 to adjust the position of the drilling equipment 15 in the radial direction of the face 5. For example, when the gantry 2 needs to move, the lifting mechanism 11 drives the drilling equipment 15 to move in the direction close to the center of the face 5 to leave walking space and avoid collision; when the face 5 needs to be drilled, the lifting mechanism 11 drives the drilling equipment 15 to move in the direction away from the center of the face 5 so that the drilling equipment 15 can be located on the outer circumference of the face 5, thereby realizing the excavation of continuous grooves and the formation of an open surface; according to actual needs, the lifting mechanism 11 drives the drilling equipment 15 to be located at a preset position in the radial direction of the face 5 to perform drilling operations at the preset position of the face 5. The specific type of the lifting mechanism 11 can be set according to actual needs and is not limited to this.

[0043] The telescopic end of the telescopic mechanism 12 is used to move along the vertical direction of the tunnel face 5 to adjust the position of the drilling equipment 15 in the vertical direction of the tunnel face 5. For example, when the tunnel face 5 needs to be drilled, the telescopic end of the telescopic mechanism 12 gradually extends as the drilling equipment 15 is drilled to advance the drilling equipment 15 until the drilling depth reaches the pre-determined depth. Then, the telescopic end of the telescopic mechanism 12 gradually retracts to achieve coring of the drilling equipment 15, thereby completing the drilling operation. The specific type of the telescopic mechanism 12 can be set according to actual needs and is not limited thereto.

[0044] The drilling equipment 15 is used for drilling operations at the face 5. The specific type of the drilling equipment 15 can be set according to actual needs, and there is no limitation on this. For example, the drilling equipment 15 can be a water-grinding drill. When the drilling is completed and the free surface is formed, the stand 2 drives each component to withdraw, and the blasting machine arrives at the excavation surface for crushing, and the slag is discharged by the loader and dump truck after crushing.

[0045] like Figure 2 and Figure 3As shown, in some embodiments, the lifting mechanism 11 includes: a first support 111, a first slide 112, a second slide 113, a first connecting rod 114, a second connecting rod 115, a first ball screw 116, a second ball screw 117 and a first driving member 118. The first support 111 is arranged on the arch frame 21, and the first slide 112 and the second slide 113 are respectively slidably arranged on the first support 111, the first connecting rod 114 is hinged between the first slide 112 and the telescopic mechanism 12, the second connecting rod 115 is hinged between the second slide 113 and the telescopic mechanism 12, the sliding directions of the first slide 112 and the second slide 113 are perpendicular to the hinge axis of the first connecting rod 114 and the second connecting rod 115, the first ball screw 116 and the second ball screw 117 are connected and rotatably arranged on the first support. The first ball screw 116 and the second ball screw 117 are on the seat 111, and the thread directions of the first ball screw 116 and the second ball screw 117 are opposite, the first ball screw 116 and the first slide 112 are threadedly connected, the second ball screw 117 is threadedly connected to the second slide 113, the driving end of the first driving member 118 is threadedly connected to the first ball screw 116 or the second ball screw 117, and the first driving member 118 is used to drive the first ball screw 116 and the second ball screw 117 to rotate, so that the first slide 112 and the second slide 113 move relative to or away from each other.

[0046] It can be understood that since the first slide 112 and the second slide 113 are respectively slidably arranged on the first support 111, and the first connecting rod 114 is hinged between the first slide 112 and the telescopic mechanism 12, and the second connecting rod 115 is hinged between the second slide 113 and the telescopic mechanism 12, when the first slide 112 and the second slide 113 move relative to or away from each other, the telescopic mechanism 12 can be lifted and lowered on the first support 111, and since the thread directions of the first ball screw 116 and the second ball screw 117 are opposite, the first ball screw 116 and the first slide 112 are threadedly connected, and the second ball screw 117 is threadedly connected to the second slide 113, and the driving end of the first driving member 118 is transmission-connected to the first ball screw 116 or the second ball screw 117, so that when the first driving member 118 drives the first ball screw 116 and the second ball screw 117 to rotate, it can drive the first slide 112 and the second slide 113 to move relative to or away from each other.

[0047] Therefore, through the cooperation of the first support 111, the first slide 112, the second slide 113, the first connecting rod 114, the second connecting rod 115, the first ball screw 116, the second ball screw 117 and the first driving member 118, the lifting function of the lifting mechanism 11 is realized, so that the radial position adjustment of the drilling equipment 15 on the face 5 is realized by utilizing the lifting function of the lifting mechanism 11, thereby realizing flexible and efficient excavation operations.

[0048] It should be noted that the first support 111 is used to carry the first slide 112, the second slide 113, the first ball screw 116, the second ball screw 117, the first driving member 118, etc. The specific type of the first support 111 can be set according to actual needs and is not limited to this. For example, the first support 111 is arranged along the vertical direction of the tunnel face 5, and the first support 111 has a guide rail, which is used for the first slide 112 and the second slide 113 to slide in the vertical direction of the tunnel face 5.

[0049] The first slide 112 and the second slide 113 are used to convert the rotation of the first ball screw 116 and the second ball screw 117 into linear movement to drive the first connecting rod 114 and the second connecting rod 115 to rotate. The specific types of the first slide 112 and the second slide 113 can be set according to actual needs and are not limited to this. For example, the first slide 112 and the second slide 113 can both be slider structures, and the first slide 112 and the second slide 113 are respectively mounted on the guide rails of the first support 111.

[0050] The first connecting rod 114 and the second connecting rod 115 are used to convert the movement of the first slide 112 and the second slide 113 into the lifting and lowering of the telescopic mechanism 12. The specific types of the first connecting rod 114 and the second connecting rod 115 can be set according to actual needs and are not limited to this. For example, one end of the first connecting rod 114 is hinged to the first slide 112, the other end of the first connecting rod 114 is hinged to one end of the telescopic mechanism 12, one end of the second connecting rod 115 is hinged to the second slide 113, and the other end of the second connecting rod 115 is hinged to the other end of the telescopic mechanism 12, and the hinge axis of the first connecting rod 114 and the hinge axis of the second connecting rod 115 are both perpendicular to the vertical direction of the palm face 5.

[0051] The first ball screw 116 and the second ball screw 117 are used to drive the linear movement of the first slide 112 and the second slide 113 by rotation. The specific types of the first ball screw 116 and the second ball screw 117 can be set according to actual needs and are not limited to this. For example, the first ball screw 116 and the second ball screw 117 are connected by a coupling, and the formed integral screw is rotatably arranged on the first support 111 by means of a bearing. The axial direction of the first ball screw 116 and the axial direction of the second ball screw 117 are both parallel to the vertical direction of the tunnel face 5.

[0052] The first driving member 118 is used to drive the first ball screw 116 and the second ball screw 117 to rotate to realize the lifting and lowering of the drilling equipment 15. The specific type of the first driving member 118 can be set according to actual needs and is not limited to this. For example, the first driving member 118 can be a manually operated handwheel, an electrically controlled motor and reducer, etc.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments, the telescopic mechanism 12 includes: a second support 121, a third slide 122, a rack 123, a gear (not shown in the figure), and a second driving member 124. The second support 121 is arranged at the lifting end of the lifting mechanism 11, and the third slide 122 is slidably arranged on the second support 121 along the vertical direction of the tunnel face 5, the drilling equipment 15 is arranged on the third slide 122, the rack 123 is arranged on the second support 121 along the vertical direction of the tunnel face 5, and the gear is rotatably arranged on the third slide 122, the gear and the rack 123 are meshed, the driving end of the second driving member 124 is connected to the gear transmission, and the second driving member 124 is used to drive the gear to rotate, so that the third slide 122 moves along the vertical direction of the tunnel face 5.

[0054] It can be understood that since the third slide 122 is slidably arranged on the second support 121 along the vertical direction of the tunnel face 5, and the drilling equipment 15 is arranged on the third slide 122, when the third slide 122 moves in the vertical direction of the tunnel face 5, the drilling equipment 15 can be extended and retracted in the vertical direction of the tunnel face 5, and since the rack 123 is arranged on the second support 121 along the vertical direction of the tunnel face 5, and the gear is rotatably arranged on the third slide 122, the gear and the rack 123 are meshed, and the driving end of the second driving member 124 is connected to the gear transmission, so that when the second driving member 124 drives the gear to rotate, the cooperation of the gear and the rack 123 can be utilized to drive the third slide 122 to move in the vertical direction of the tunnel face 5.

[0055] Therefore, through the cooperation of the second support 121, the third slide 122, the rack 123, the gear and the second driving member 124, the telescopic function of the telescopic mechanism 12 is realized, so that the position of the drilling equipment 15 in the vertical direction of the tunnel face 5 can be adjusted by utilizing the telescopic function of the telescopic mechanism 12, thereby realizing flexible and efficient excavation operations.

[0056] It should be noted that the second support 121 is used to carry the third slide 122, the rack 123, the second driving member 124, etc. The specific type of the second support 121 can be set according to actual needs and is not limited to this. For example, the second support 121 is arranged along the vertical direction of the palm face 5, and the second support 121 has a guide rail, which is used for the third slide 122 to slide in the vertical direction of the palm face 5.

[0057] The third slide 122 is used to carry the drilling equipment 15. The specific type of the third slide 122 can be set according to actual needs and is not limited to this. For example, the third slide 122 can be a slider structure, and the third slide 122 is mounted on the guide rail of the second support 121.

[0058] The rack 123 and the gear are used for transmission between the second driving member 124 and the third slide 122 to convert rotational motion into linear motion. The specific types of the rack 123 and the gear can be set according to actual needs and are not limited to this. For example, the rack 123 is arranged along the vertical direction of the palm face 5, and the axial direction of the gear is perpendicular to the vertical direction of the palm face 5.

[0059] The second driving member 124 is used to drive the gear to rotate to achieve the extension and retraction of the drilling equipment 15. The specific type of the second driving member 124 can be set according to actual needs and is not limited to this. For example, the second driving member 124 can be an electrically controlled motor and reducer, etc.

[0060] like Figure 2 As shown, in some embodiments, the drilling device 1 also includes: an angle adjustment mechanism 13, the angle adjustment mechanism 13 is arranged between the lifting mechanism 11 and the telescopic mechanism 12, and the angle adjustment mechanism 13 is arranged at the lifting end of the lifting mechanism 11, and the telescopic mechanism 12 is arranged at the adjustment end of the angle adjustment mechanism 13, and the adjustment end of the angle adjustment mechanism 13 is used to rotate around the width direction of the tunnel face 5.

[0061] It can be understood that since the angle adjustment mechanism 13 is arranged at the lifting end of the lifting mechanism 11, and the telescopic mechanism 12 is arranged at the adjusting end of the angle adjustment mechanism 13, the drilling equipment 15 can utilize the angle adjustment mechanism 13 to rotate around the width direction of the face 5, thereby realizing flexible adjustment of the angle of the drilling equipment 15, and then adapting to the drilling requirements of different angles of the face 5, and realizing high-efficiency and high-precision excavation operations of the face 5.

[0062] It should be noted that the adjusting end of the angle adjustment mechanism 13 is used to rotate around the width direction of the tunnel face 5 to achieve angle adjustment of the drilling equipment 15. The specific type of the angle adjustment mechanism 13 can be set according to actual needs and is not limited to this.

[0063] Among them, the adjusting end of the angle adjustment mechanism 13 rotates around the width direction of the tunnel face 5 to adjust the drilling angle of the drilling equipment 15, that is, adjusts the angle between the drilling axis and the vertical direction of the tunnel face 5 in the vertical plane, which can also be called adjusting the elevation angle of the drilling equipment 15.

[0064] like Figure 2 and Figure 3As shown, in some embodiments, the angle adjustment mechanism 13 includes: a third support 131 and a third driving member 132. The third support 131 is arranged at the lifting end of the lifting mechanism 11, and the end of the telescopic mechanism 12 away from the tunnel face 5 is hinged to the end of the third support 131 away from the tunnel face 5, the hinge axis of the telescopic mechanism 12 is perpendicular to the vertical direction of the tunnel face 5, the driving end of the third driving member 132 is connected to the telescopic mechanism 12 by transmission, and the third driving member 132 is used to drive the telescopic mechanism 12 to rotate around the width direction of the tunnel face 5.

[0065] It can be understood that, since the end of the telescopic mechanism 12 away from the tunnel face 5 is hinged to the end of the third support 131 away from the tunnel face 5, the driving end of the third driving member 132 is transmission-connected with the telescopic mechanism 12, so that the third driving member 132 can drive the telescopic mechanism 12 to rotate around the width direction of the tunnel face 5, thereby realizing the angle adjustment function of the angle adjustment mechanism 13. Therefore, by using the angle adjustment function of the angle adjustment mechanism 13, the angle adjustment of the drilling equipment 15 can be realized, thereby realizing flexible and efficient excavation operations.

[0066] It should be noted that the third support 131 is used to carry the third driving member 132, the telescopic mechanism 12, etc. The specific type of the third support 131 can be set according to actual needs and is not limited to this. For example, the third support 131 is arranged along the vertical direction of the tunnel face 5, that is, the third support 131 and the first support 111 are arranged in parallel.

[0067] The third driving member 132 is used to drive the telescopic mechanism 12 to rotate around the width direction of the tunnel face 5. The specific type of the third driving member 132 can be set according to actual needs and is not limited to this. For example, the third driving member 132 can be a hydraulic cylinder, which is arranged between the third support 131 and the telescopic mechanism 12, and the hinge axis between the telescopic mechanism 12 and the third support 131 and the hinge axis between the telescopic mechanism 12 and the third support 131 are both perpendicular to the vertical direction of the tunnel face 5.

[0068] Furthermore, one end of the first connecting rod 114 away from the first slide 112 is hinged to one end of the third support 131, one end of the second connecting rod 115 away from the second slide 113 is hinged to the other end of the third support 131, one end of the second support 121 is hinged to one end of the third support 131, and the third driving member 132 is arranged between the other end of the second support 121 and the other end of the third support 131.

[0069] When the third driving member 132 is not in motion, the telescopic end of the telescopic mechanism 12 telescopes in a direction perpendicular to the palm face 5 , and when the third driving member 132 is in motion, the telescopic end of the telescopic mechanism 12 telescopes in a direction after the angle is adjusted.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, the arch 21 is sequentially provided with a plurality of drilling areas 22 along the circumference of the tunnel face 5, and a plurality of drilling devices 1 are respectively located in the plurality of drilling areas 22; the drilling device 1 further comprises: a position adjustment mechanism 14, the position adjustment mechanism 14 is arranged between the lifting mechanism 11 and the arch 21, and the position adjustment mechanism 14 is located in the drilling area 22, the lifting mechanism 11 is arranged at the adjustment end of the position adjustment mechanism 14, and the adjustment end of the position adjustment mechanism 14 is used to move in the drilling area 22 along the circumference of the tunnel face 5.

[0071] It can be understood that since the position adjustment mechanism 14 is located in the drilling area 22 and the lifting mechanism 11 is arranged at the adjustment end of the position adjustment mechanism 14, the drilling equipment 15 can utilize the position adjustment mechanism 14 to move in the drilling area 22 along the circumference of the tunnel face 5, thereby realizing flexible adjustment of the circumferential position of the drilling equipment 15 on the tunnel face 5, thereby adapting to the drilling requirements at different positions of the tunnel face 5, and realizing high-efficiency and high-precision excavation operations of the tunnel face 5.

[0072] It should be noted that the adjustment end of the position adjustment mechanism 14 is used to move in the drilling area 22 along the circumference of the tunnel face 5 to achieve position adjustment of the drilling device 15 in the drilling area 22. For example, when the tunnel face 5 needs to be drilled, the position adjustment mechanism 14 drives the drilling device 15 to move in sequence along the circumference of the tunnel face 5, so as to form a continuous channel using multiple drill holes in the drilling area 22, and then form an open face. The specific type of the position adjustment mechanism 14 can be set according to actual needs and is not limited to this.

[0073] Among them, by distributing multiple drilling devices 1 in multiple drilling areas 22, segmented synchronous drilling of the outer circumference of the tunnel face 5 is achieved, so that by utilizing the cooperation of multiple drilling devices, efficient excavation operations of the tunnel face 5 can be achieved.

[0074] like Figure 2 and Figure 3 As shown, in some embodiments, the position adjustment mechanism 14 includes: a fourth support 141 and a fourth driving member (not shown in the figure). The fourth support 141 is slidably arranged in the drilling area 22 along the circumference of the tunnel face 5, and the lifting mechanism 11 is arranged on the fourth support 141, the driving end of the fourth driving member is connected to the fourth support 141 by transmission, and the fourth driving member is used to drive the fourth support 141 to move in the drilling area 22 along the circumference of the tunnel face 5.

[0075] It can be understood that, since the fourth support 141 is slidably arranged in the drilling area 22 along the circumferential direction of the tunnel face 5, and the driving end of the fourth driving member is transmission-connected with the fourth support 141, the fourth driving member can drive the fourth support 141 to move in the drilling area 22 along the circumferential direction of the tunnel face 5, thereby realizing the position adjustment function of the position adjustment mechanism 14. Therefore, by utilizing the position adjustment function of the adjustment mechanism, the position adjustment of the drilling equipment 15 in the drilling area 22 can be realized, thereby realizing flexible and efficient excavation operations.

[0076] It should be noted that the fourth support 141 is used to carry the fourth driving member, the lifting mechanism 11, etc. The specific type of the fourth support 141 can be set according to actual needs and is not limited to this. For example, the fourth support 141 can be a two-seat structure, and the two seats are respectively clamped on the lower wing plate of the I-beam of the arch frame 21 using rollers arranged opposite to each other.

[0077] The fourth driving member is used to drive the fourth support 141 to move in the drilling area 22 along the circumference of the tunnel face 5. The specific type of the fourth driving member can be set according to actual needs and is not limited to this. For example, the fourth driving member can be a manual hoist, an electric hoist, etc., and the movement and positioning of the fourth support 141 are achieved by dragging the fourth driving member and the deadweight of the drilling equipment 15, etc.

[0078] like Figure 4 As shown, in some embodiments, the walking device 3 includes: a walking wheel 31 and a fifth driving member 32, the walking wheel 31 is rotatably arranged at the bottom of the stand 2, and the driving end of the fifth driving member 32 is transmission-connected to the walking wheel 31, and the fifth driving member 32 is used to drive the walking wheel 31 to rotate.

[0079] It can be understood that since the walking wheel 31 is rotatably set at the bottom of the platform 2, and the driving end of the fifth driving member 32 is transmission-connected to the walking wheel 31, the fifth driving member 32 can drive the walking wheel 31 to rotate, thereby realizing the walking of the platform 2, and further facilitating the flexible drilling operation of multiple drilling devices 1.

[0080] It should be noted that the running wheels 31 are used for the running of the platform 2, and the specific type of the running wheels 31 can be set according to actual needs, and there is no limitation on this.

[0081] The fifth driving member 32 is used to drive the travel wheel 31 to rotate. The specific type of the fifth driving member 32 can be set according to actual needs and is not limited to this. For example, the fifth driving member 32 can be a motor, and the motor uses a chain transmission between two sprockets to drive the travel wheel 31.

[0082] like Figure 5As shown, in some embodiments, the drilling system further includes: a positioning device 4, which includes: a fifth support 41, a sixth driving member (not shown in the figure), a support shoe 42 and a seventh driving member 43. The fifth support 41 is slidably arranged at the bottom of the platform 2 along the height direction of the tunnel face 5, and the driving end of the sixth driving member is connected to the fifth support 41 by transmission, and the sixth driving member is used to drive the fifth support 41 to move vertically, the support shoe 42 is slidably arranged at the bottom of the fifth support 41 along the width direction of the tunnel face 5, and the driving end of the seventh driving member 43 is connected to the support shoe 42 by transmission, and the seventh driving member 43 is used to drive the support shoe 42 to move along the width direction of the tunnel face 5.

[0083] It can be understood that, since the fifth support 41 is slidably arranged at the bottom of the platform 2 along the height direction of the tunnel face 5, and the driving end of the sixth driving member is connected to the fifth support 41 by transmission, the sixth driving member can drive the fifth support 41 to move vertically, and at the same time, since the shoe 42 is slidably arranged at the bottom of the fifth support 41 along the width direction of the tunnel face 5, and the driving end of the seventh driving member 43 is connected to the shoe 42 by transmission, the seventh driving member 43 can drive the shoe 42 to move along the width direction of the tunnel face 5. Therefore, through the cooperation of the sixth driving member and the seventh driving member 43, the platform 2 can be effectively supported by the fifth support 41 and the shoe 42 and the positioning of the platform 2 can be achieved, thereby ensuring the stable excavation of the tunnel face 5.

[0084] It should be noted that the positioning device 4 is used for positioning and position adjustment of the stand 2. For example, when the sixth driving member drives the fifth support 41 to move in a direction close to the tunnel floor, the support shoe 42 can be used to support the stand 2, so that the walking device 3 is away from the floor, thereby achieving the positioning of the stand 2; when the support shoe 42 supports the stand 2 and the seventh driving member 43 is used to drive the support shoe 42 to move along the width direction of the tunnel face 5, the overall position of the stand 2 in the width direction of the tunnel face 5 can be adjusted.

[0085] The fifth support 41 is used to support the stand 2 using the support shoe 42. The specific type of the fifth support 41 can be set according to actual needs and is not limited to this. For example, the fifth support 41 is slidably set at the bottom of the stand 2 along the vertical direction using a sleeve.

[0086] The sixth driving member is used to drive the fifth support 41 to move vertically. The specific type of the sixth driving member can be set according to actual needs and is not limited to this. For example, the sixth driving member can be a hydraulic cylinder that is hinged between the fifth support 41 and the stand 2.

[0087] The support shoe 42 is used to abut against the tunnel floor and form the stand 2. The specific type of the support shoe 42 can be set according to actual needs and is not limited to this. For example, the support shoe 42 is slidably clamped in the slide groove at the bottom of the fifth support 41.

[0088] The seventh driving member 43 is used to drive the support shoe 42 to move along the width direction of the tunnel face 5. The specific type of the seventh driving member 43 can be set according to actual needs and is not limited to this. For example, the seventh driving member 43 can be a hydraulic cylinder, and the seventh driving member 43 is arranged between the support shoe 42 and the fifth support 41.

[0089] In some embodiments, the platform 2 is provided with at least one walkway board arranged in the horizontal direction, and the platform 2 is provided with at least one fence arranged in the vertical direction, and the fence is located outside the walkway board.

[0090] It can be understood that since the platform 2 is provided with at least one walkway board arranged in the horizontal direction, and the platform 2 is provided with at least one fence arranged in the vertical direction, the fence is located on the outside of the walkway board, so that the operators can use the walkway board to realize walking operations on the platform 2. At the same time, the safety of the operators on the platform 2 can also be guaranteed by the isolation of the fence.

[0091] In some embodiments, the platform 2 is provided with at least one ladder arranged in the vertical direction.

[0092] It can be understood that, since the platform 2 is provided with at least one ladder arranged in the vertical direction, the operator can use the ladder to climb onto the platform 2, thereby making the use of the drilling system more convenient.

[0093] In some embodiments, the scaffolds 2 are arranged along the circumference of the tunnel face 5 and form an avoidance channel 23 .

[0094] It can be understood that since the gantry 2 is arranged along the circumference of the tunnel face 5 and forms an avoidance channel 23, other excavation equipment in the tunnel can use the avoidance channel 23 to pass through the gantry 2, thereby achieving efficient operation of the drilling system while reducing the impact of the drilling system on the operation of other equipment.

[0095] Based on the drilling system of this embodiment, the following tunnel face 5 excavation method can be implemented:

[0096] S1: The drilling system is moved to the tunnel face 5, and the posture of the frame 2 is adjusted by the cooperation of the walking device 3 and the positioning device 4 so that the center of the frame 2 is consistent with the center of the tunnel, and then the positioning device 4 is used to stably support the frame 2 in the tunnel;

[0097] S2: After adjusting the position and angle of the multiple drilling devices 1 on the arch frame 21, the outer circumference of the tunnel face 5 is drilled with a drilling depth of 1 m to form an open surface on the outer circumference of the tunnel. A total of 160 holes can be drilled, and the efficiency of a single hole is 5 min / hole.

[0098] S3: Use the lifting mechanism 11 to lower the height of the drilling equipment 15 on the arch 21, then move the platform 2 backward, and the blasting machine arrives at the excavation surface for crushing, wherein the excavation distance is 1m, and the slag is discharged by the loader and dump truck after excavation;

[0099] S4: The gun moves backward and the carriage 2 moves forward, forming a cycle.

[0100] Therefore, the "drilling + excavation + slag removal" method is repeated three times, with each excavation being 1m, to provide initial support for the excavated tunnel.

[0101] Compared with the manual excavation method using a single water-grinding drill, the drilling system of this embodiment can achieve a penetration of 0.8m, an increase of 60%. Taking 100 holes per cycle as an example, it takes 3 hours and 5 hours to complete each cycle in sandy mudstone and sandstone, respectively, saving 50% and 30% of the time, respectively.

[0102] The drilling system of this embodiment adds a drilling and coring process on the basis of direct excavation by a traditional breaker hammer excavator. Through the integrated stand 2, multiple sets of drilling equipment 15 are constructed simultaneously to quickly form an empty face on the face 5. The blasting machine excavation can greatly improve the construction efficiency on the premise of forming an empty face, and solves the problem of over-excavation and under-excavation of the face 5.

[0103] The drilling system of this embodiment integrates multiple sets of drilling equipment 15 on the mobile platform 2. The equipment has a high degree of automation and can move forward, backward and left and right independently. It can fit the cross-sectional contour according to the cross-sectional conditions and drill multiple holes at the same time, which greatly improves the drilling efficiency and reduces the intensity of manual labor.
