[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following description, with reference to the accompanying drawings, describes an anchor drilling rig for coal roadway borehole support provided by an embodiment of the present invention.

[0043] like Figures 1 to 9 As shown, the rock bolt drilling rig for coal roadway drilling support according to an embodiment of the present invention includes a body 1, a robotic arm assembly 2, a drilling rig 3, a walking device 6, and a power device 7. The body 1 is the basic structure of the rock bolt drilling rig and is used to install various components. The drilling rig 3 is used to drill holes in the roadway and anchor the rock bolts. The drilling rig 3 is connected to the body 1 through the robotic arm assembly 2, and the drilling rig 3 can move flexibly with the robotic arm assembly 2, which facilitates rock bolt support at different locations in the roadway.

[0044] Specifically, one end of the robotic arm assembly 2 is connected to the vehicle body 1, and the robotic arm assembly 2 has multiple degrees of freedom to adjust the position of the drilling rig 3.

[0045] The drilling rig 3 includes a drill frame 31 and a drilling and injection assembly 32. The drill frame 31 is connected to the other end of the robotic arm assembly 2, and the drilling and injection assembly 32 is connected to the drill frame 31 and is movable along the length of the drill frame 31.

[0046] The drilling assembly 32 includes a stroke slide bar 321 and a static fluid drill box 10. The static fluid drill box 10 is used to install drill rods and / or anchor bolts. The static fluid drill box 10 is connected to the stroke slide bar 321 and can move along the length of the stroke slide bar 321. The robotic arm assembly 2 first moves the drill frame 31 to the preset anchoring position. Drill rods or anchor bolts are connected to the static fluid drill box 10. The static fluid drill box moves the drill rods or anchor bolts, thereby performing anchor bolt support operations on the surrounding rock in the roadway.

[0047] Specifically, such as Figures 7 to 12 As shown, the statically stable fluid drilling box 10 includes: a base 101, a first rotating shaft 102, a second rotating shaft 103, an anchoring component 104, a driving component 105, and a transmission component 106.

[0048] A first rotating shaft 102 is rotatably mounted on a base 101. The first rotating shaft 102 has a first through hole 1021 extending along its length. At least a portion of a second rotating shaft 103 fits within the first through hole 1021. The second rotating shaft 103 is movable along the length of the first rotating shaft 102. The second rotating shaft 103 has a second pipe through hole 1031 extending along its length. An anchoring member 104 is slidably mounted on the base 101. The anchoring member 104 passes through the second pipe through hole 1031 and is rotatably connected to the second rotating shaft 103. The anchoring member 104 has multiple fluid channels 1043 communicating with the first through hole 1021. A driving member 105 is mounted on the base 101 and is connected to the first rotating shaft 102 via a transmission member 106 to drive the first rotating shaft 102 to rotate.

[0049] The base 101 is L-shaped and includes a horizontal section and a vertical section. The front end of the horizontal section of the base 101 is connected to the lower end of the vertical section of the base 101, and the interior of the vertical section of the base 101 has a receiving cavity.

[0050] Understandably, the first rotating shaft 102 is used to connect with an anchor rod or drill rod (not shown in the figure) for construction to achieve drilling operations. For example, the anchor rod can be inserted into the first through hole 1021 from the front side of the first rotating shaft 102. The inlets of the multiple fluid channels 1043 on the anchoring component 104 correspond one-to-one with multiple medium sources, including water sources, anchoring agents, etc. The anchoring agents include one of resin anchoring agents, pumpable organic anchoring agents, or cement anchoring agents. For example, during drilling, one fluid channel 1043 delivers water to the anchor rod to clean up the coal slag generated during the drilling process. During anchoring, the water supply is turned off, and the other fluid channels 1043 supply anchoring agents to the anchor rod to anchor the anchor rod and the surrounding rock together.

[0051] Furthermore, the anchoring element 104 is slidably mounted on the base 101 in the front-to-back direction, and the second rotating shaft 103 is rotatably connected to the anchoring element 104, so that the second rotating shaft 103 can drive the anchoring element 104 to move in the front-to-back direction during its movement. Moreover, the second rotating shaft 103 can rotate relative to the anchoring element 104, thereby preventing the first rotating shaft 102 from driving the anchoring element 104 to rotate, so that the fluid channel 1043 does not need to rotate with the first rotating shaft 102, thus making the fluid channel 1043 suitable for conveying easily reactive and easily volatile fluid media. Therefore, the second rotating shaft 103 serves as a connecting element between the first rotating shaft 102 and the anchoring element 104.

[0052] Those skilled in the art will understand that the rotation direction during anchor drilling is opposite to the rotation direction during pre-tightening after drilling is completed. For example, if the first shaft 102 rotates clockwise to drive the anchor bolt for drilling, then after the anchor bolt is drilled and anchored, the first shaft 102 rotates counterclockwise to drive the anchor bolt for pre-tightening. Furthermore, during pre-tightening, the portion of the anchor bolt located within the first through hole 1021 will move closer to the anchoring element 104. To avoid interference from the anchoring element 104, the second shaft 103 moves, thereby moving the anchoring element 104 away from the anchor bolt, thus ensuring the normal implementation of the pre-tightening operation.

[0053] The transmission component 106 is located in the receiving cavity of the base 101. The input end of the transmission component 106 is connected to the drive component 105, and the output end of the transmission component 106 is connected to the first rotating shaft 102, so that after the drive component 105 is started, the first rotating shaft 102 is driven to rotate through the transmission effect of the transmission component 106.

[0054] Therefore, the drive component 105 drives the first rotating shaft 102 to rotate via the transmission component 106, thereby realizing the construction operations of anchor bolt drilling and pre-tightening. Fluid medium is delivered to the anchor bolt through the fluid channel 1043 of the anchoring component 104, thus achieving the anchor bolt anchoring operation. Furthermore, the second rotating shaft 103 drives the anchoring component 104 to move, avoiding interference between the anchoring component 104 and the anchor bolt during the anchoring process. The second rotating shaft 103 is also rotatable relative to the anchoring component 104, further preventing the fluid channel 1043 from rotating relative to the surrounding environment during operation, making the fluid channel 1043 suitable for conveying easily reactive and volatile fluid media.

[0055] It should be noted that the robotic arm assembly 2 in this embodiment of the invention has six degrees of freedom, enabling the construction of all top anchor bolts, left side anchor bolts, and right side anchor bolts within two roadway spacings without moving the anchor bolt drilling rig. This ensures that the anchor bolt drilling rig can perform drilling and anchoring operations on the surrounding rock at any location in complex roadway environments.

[0056] The traveling device 6 is located at the bottom of the vehicle body 1 to drive the anchor drilling rig along the roadway. The power unit 7 is used to provide power to the robotic arm assembly 2, the drilling rig 3 and the traveling device 6. The power unit 7 consists of an oil tank, an explosion-proof motor, a hydraulic pump, an electromagnetic starter, a cooler and other components. The power source of the whole vehicle is provided by an electric-driven hydraulic pump station. The power unit 7 of the anchor drilling rig is a mature existing technology and will not be described in detail.

[0057] The rock bolt drilling rig for coal roadway drilling support according to the present invention has a robotic arm assembly 2 with multiple degrees of freedom, which ensures that the rock bolt drilling rig can perform drilling and anchoring operations on the surrounding rock at any location in complex roadway environments. Moreover, it has a high degree of mechanization, which greatly improves the efficiency of rock bolt support in the roadway.

[0058] In some embodiments, the robotic arm assembly 2 includes a mounting base 21, a telescopic arm 22, and a connecting device 23. The mounting base 21 is rotatably connected to the vehicle body 1. The telescopic arm 22 is telescopic along its length. One end of the telescopic arm 22 is rotatably connected to the mounting base 21. One end of the connecting device 23 is connected to the other end of the telescopic arm 22. The connecting device 23 is movable along its length. The drilling rig 3 is rotatably connected to the connecting device 23.

[0059] The mounting base 21 is rotatable relative to the vehicle body 1, meaning it can swing left and right in the horizontal direction, thereby causing the telescopic arm 22 to swing. The telescopic arm 22 is also rotatable relative to the mounting base 21, meaning it can swing up and down in the vertical direction, thereby adjusting its pitch angle. The telescopic arm 22 is extendable and retractable, thereby adjusting the position of the drilling rig 3. The connecting device 23 can move along its length, further adjusting the position of the drilling rig 3 to increase its maximum stroke. Furthermore, the adjustment of the connecting device 23 is a fine-tuning adjustment, allowing for precise adjustment of the drilling rig's position. The position of drill 3; furthermore, drill 3 is rotatable relative to connecting device 23, meaning that drill 3 can rotate circumferentially along connecting device 23, allowing drill 3 to drill and anchor to different wall surfaces. For example, if drill 3 is set vertically, it can drill holes in the top surrounding rock; if drill 3 is set horizontally, it can drill holes in the surrounding rock on both sides. In addition, drill 3 can also rotate in the front-back direction relative to connecting device 23, that is, drill 3 can tilt forward or backward. Due to the unevenness of the tunnel wall, the inclined setting of drill 3 can drill and anchor to wall surfaces at different angles. Thus, drill 3 can perform six different movements, that is, it has six degrees of freedom.

[0060] In some embodiments, the robotic arm assembly 2 includes a first axis and a second axis. The first axis is vertically arranged, and the mounting base 21 is rotatably connected to the vehicle body 1 through the first axis, thereby enabling the mounting base 21 to swing left and right. The second axis is horizontally arranged, and the telescopic arm 22 is rotatably connected to the mounting base 21 through the second axis, thereby enabling the telescopic arm 22 to swing up and down.

[0061] Furthermore, the robotic arm assembly 2 also includes a first telescopic cylinder 24, which is horizontally positioned. One end of the cylinder body of the first telescopic cylinder 24 is rotatably connected to the vehicle body 1, and one end of the piston rod of the first telescopic cylinder 24 is rotatably connected to the telescopic arm 22. When the piston rod of the first telescopic cylinder 24 moves along the cylinder body, it can drive the telescopic arm 22 to swing left and right.

[0062] In some embodiments, the telescopic arm 22 includes a first telescopic arm 221 and a second telescopic arm 222, the first telescopic arm 221 and the second telescopic arm 222 are parallel to each other, and there is a gap between the first telescopic arm 221 and the second telescopic arm 222.

[0063] With this configuration, the mounting base 21, the first telescopic arm 221, the connecting device 23, and the second telescopic arm 222 are connected in sequence to form a four-bar linkage. The four-bar linkage can provide better support for the drilling rig 3, so that the drilling rig 3 can be relatively fixed to the surrounding rock when the anchor drilling rig is working, preventing the drilling rig 3 from shifting during the drilling process.

[0064] Furthermore, a second telescopic cylinder (not shown) is also provided inside the first telescopic arm 221. The first telescopic arm 221 includes a first section and a second section. The first section is sleeved on the outside of the second section. The second section is telescopic along the first section. The second telescopic cylinder is located inside the first section. One end of the cylinder body of the second telescopic cylinder is connected to one end of the first section adjacent to the mounting seat 21. One end of the piston rod of the second telescopic cylinder is connected to the second section.

[0065] Therefore, the piston rod of the second telescopic cylinder extends and retracts along the cylinder body, which in turn drives the first telescopic arm 221 to extend and retract, thereby adjusting the length of the first telescopic arm 221 and thus adjusting the position of the drilling rig 3.

[0066] Similarly, the robotic arm assembly 2 also includes a third telescopic cylinder 26. The second telescopic arm 222 includes a third segment and a fourth segment. The third segment is sleeved on the outside of the fourth segment. The fourth segment is telescopic along the third segment. The cross-sectional area of ​​the second telescopic arm 222 is relatively small, so the third telescopic cylinder 26 is located on the outside of the second telescopic arm 222.

[0067] One end of the cylinder body of the third telescopic cylinder 26 is connected to one end of the third section adjacent to the mounting base 21, and one end of the piston rod of the third telescopic cylinder 26 is connected to the fourth section. The piston rod of the third telescopic cylinder 26 extends and retracts along the cylinder body, which drives the second telescopic arm 222 to extend and retract, thereby adjusting the length of the second telescopic arm 222 and thus adjusting the position of the drilling rig 3.

[0068] It should be noted that when adjusting the length of the telescopic arm 22, the second telescopic cylinder and the third telescopic cylinder 26 should operate simultaneously to ensure that the first telescopic arm 221 and the second telescopic arm 222 can extend or shorten at the same time.

[0069] In some embodiments, the robotic arm assembly 2 further includes a fourth telescopic cylinder 27, one end of the cylinder body of the fourth telescopic cylinder 27 being rotatably connected to the mounting base 21, and one end of the piston rod of the fourth telescopic cylinder 27 being rotatably connected to the first telescopic arm 221.

[0070] The piston rod of the fourth telescopic cylinder 27 extends and retracts along the cylinder body, which can drive the first telescopic arm 221 to swing up and down. At the same time, it can also drive the second telescopic arm 222 to swing up and down simultaneously with the first telescopic arm 221, thereby adjusting the pitch angle of the telescopic arm 22.

[0071] The robotic arm assembly 2 also includes a slide 29 and a fifth telescopic cylinder (not shown). The slide 29 is connected to the telescopic arm 22. The connecting device 23 is disposed in the slide 29 and is connected to the telescopic arm 22 through the slide 29. The connecting device 23 can slide in the slide 29. Since the drilling rig 3 is connected to the connecting device 23, the sliding of the connecting device 23 can drive the drilling rig 3 to move, so as to make fine adjustments to the position of the drilling rig 3. In conjunction with the telescopic arm 22, the drilling rig 3 has a large stroke.

[0072] One end of the cylinder body of the fifth telescopic cylinder is connected to the slide rail 29, and one end of the piston rod of the fifth telescopic cylinder is connected to the connecting device 23. When the piston rod of the fifth telescopic cylinder extends and retracts along the cylinder body, it can drive the connecting device 23 to slide along the slide rail 29.

[0073] In some embodiments, the connecting device 23 includes a mounting plate 231 and a rotary cylinder 232. The mounting plate 231 is connected to the fifth telescopic cylinder, the rotary cylinder 232 is connected to the mounting plate 231, and the output shaft of the rotary cylinder 232 is connected to the drilling rig 3.

[0074] In other words, the connecting device 23 includes a mounting plate 231 and a rotary cylinder 232 mounted on the mounting plate 231. The rotary cylinder 232 is used to drive the drilling rig 3 to rotate. One end of the piston rod of the fifth telescopic cylinder is connected to the mounting plate 231. The action of the fifth telescopic cylinder drives the mounting plate 231 to move, thereby driving the rotary cylinder 232 and the drilling rig 3 to move.

[0075] In addition, the connecting device 23 also includes a third connecting member 233 and a sixth telescopic cylinder 234. The third connecting member 233 is used to connect the drilling rig 3 and the connecting device 23. The third connecting member 233 is plate-shaped. One end of the third connecting member 233 is connected to the mounting plate 231, and the other end of the third connecting member 233 is rotatably connected to the drilling rig 3. One end of the cylinder body of the sixth telescopic cylinder 234 is rotatably connected to the mounting plate 231 or the third connecting member 233, and one end of the piston rod of the sixth telescopic cylinder 234 is rotatably connected to the drilling rig 3.

[0076] With this configuration, the piston rod of the sixth telescopic cylinder 234 can extend and retract along the cylinder body, thereby driving the drilling rig 3 to tilt forward or backward, thus meeting the different angle requirements of the drilling rig 3.

[0077] The rock bolt drilling rig for coal roadway borehole support in this embodiment of the invention has a telescopic boom 22 with a left-right swing angle of 40 degrees, a pitch adjustment angle of 55 degrees, a telescopic boom 22 with a length extension distance of 700 mm, a connecting device 23 with a movement distance of 400 mm, a drilling rig 3 with a left-right rotation angle of 125 degrees, and a front-back rotation angle of 30 degrees. These design parameters, combined with the long-stroke hydraulic drilling rig 3, enable the construction of all top rock bolts, left side rock bolts, and right side rock bolts within two roadway spacings without moving the rock bolt drilling rig when it is located in the middle of the roadway. Compared to conventional rock bolt drilling rigs, this saves time spent moving the rig left and right, effectively improving the roadway support efficiency.

[0078] In some embodiments, there are two robotic arm assemblies 2, which are arranged at intervals along the width direction of the vehicle body 1. Each robotic arm assembly 2 is connected to a drilling rig 3. The two robotic arm assemblies 2 can simultaneously operate the two drilling rigs 3 to perform drilling or anchor bolt support, which can effectively improve the working efficiency of the anchor bolt drilling rig.

[0079] In some embodiments, the drill frame 31 includes a frame 311 and a support slide 312. The frame 311 is provided with a first through hole and a second through hole. The extension direction of the first through hole and the extension direction of the second through hole are parallel to each other. The support slide 312 passes through the first through hole and can slide along the first through hole.

[0080] The drilling assembly 32 includes multiple stroke slides 321 and a static fluid drilling box 10. At least one stroke slide 321 passes through the second through hole and is slidable along the second through hole. The static fluid drilling box 10 is connected to at least one stroke slide 321 and can move along the length of the stroke slide 321.

[0081] In related technologies, anchor drilling rigs generally adopt a V-groove guide rail slider structure to adjust the position of the statically stable fluid drilling box 10. However, the motion coordination accuracy of this type of anchor drilling rig is low, and it is prone to deformation during operation.

[0082] In this embodiment, the drilling rig 3 uses a sliding column guide rail structure instead of the V-groove fit method in the traditional hydraulic anchor drilling rig. Compared with the V-groove structure, the sliding column guide rail structure has more complete motion constraints, thereby improving the fit accuracy of sliding motion. At the same time, it can ensure the structural strength of the anchor drilling rig and will not cause structural deformation due to the fit accuracy of motion during use, thus improving the construction position accuracy of the anchor drilling rig.

[0083] In some embodiments, the first through hole 1021 includes an anchor section 211 and a relief section 212. The relief section 212 is provided with an internal thread, and the outer peripheral wall of the second rotating shaft 103 is provided with an external thread that matches the internal thread. The second rotating shaft 103 located in the relief section 212 is connected to the relief section 212 by a thread.

[0084] It is understandable that the rotation direction of the first rotating shaft 102 is the drilling rotation direction. When the threads of the first rotating shaft 102 and the second rotating shaft 103 are not fully engaged, the first rotating shaft 102 drives the second rotating shaft 103 to translate relative to the base 101 towards the anchor rod. After the threads are fully engaged, the second rotating shaft 103 rotates relative to the base 101. The rotation direction of the first rotating shaft 102 is the pre-tightening rotation direction, and the second rotating shaft 103 translates relative to the base 101 away from the anchor rod.

[0085] Understandably, under the action of the threaded pair, when the first rotating shaft 102 and the second rotating shaft 103 rotate relative to each other, the second rotating shaft 103 will move relative to the first rotating shaft 102 in the front-back direction. Furthermore, the friction between the internal thread of the first rotating shaft 102 and the external thread of the second rotating shaft 103 is much smaller than the friction between the second rotating shaft 103 and the anchor 104, ensuring that when the internal and external threads are not fully engaged, the first rotating shaft 102 rotates and drives the second rotating shaft 103 to move in the front-back direction, thereby driving the anchor 104 to move in the front-back direction.

[0086] For example, the internal thread of the first rotating shaft 102 and the external thread of the second rotating shaft 103 are in a fully engaged state. In this state:

[0087] If the first rotating shaft 102 rotates clockwise, the second rotating shaft 103 cannot move forward relative to the first rotating shaft 102 because the internal and external threads are fully engaged. Therefore, the first rotating shaft 102 drives the second rotating shaft 103 to rotate synchronously, allowing for the drilling of the anchor bolt. Furthermore, since the second rotating shaft 103 is rotatably connected to the anchoring component 104, the anchoring component 104 is prevented from rotating.

[0088] If the first rotating shaft 102 reverses, since the second rotating shaft 103 can move backward relative to the first rotating shaft 102, and the frictional force of the threads between the first rotating shaft 102 and the second rotating shaft 103 is less than the frictional force of the rotation between the second rotating shaft 103 and the anchoring member 104, the first rotating shaft 102 drives the second rotating shaft 103 to move backward, thereby driving the anchoring member 104 to move backward, so that the anchor bolt pre-tightening operation can be performed.

[0089] Therefore, the first rotating shaft 102 rotates clockwise and drives the anchor rod to perform drilling operations, and the first rotating shaft 102 rotates counterclockwise and drives the anchor rod to perform pre-tightening operations. Furthermore, when the first rotating shaft 102 rotates counterclockwise, it simultaneously drives the anchor injection component 104 to move backward, so as to avoid the anchor injection component 104 interfering with the pre-tightening of the anchor rod.

[0090] Similarly, the internal thread of the first rotating shaft 102 and the external thread of the second rotating shaft 103 are not fully engaged. At this time, the first rotating shaft 102 rotates forward and drives the second rotating shaft 103 to move forward, thereby driving the anchor 104 to move forward until the internal and external threads are fully engaged and the anchor 104 stops moving forward.

[0091] Furthermore, the distance between the anchor rod and the anchoring element 104 within the first through hole 1021 is kept infinitely close. This ensures a small gap between them while preventing contact, thus preventing a large amount of fluid medium delivered by the anchoring element 104 from entering the first through hole 1021. Additionally, depending on the actual working conditions, the pitch of the internal and external threads must be greater than or equal to the pitch of the tail thread of the construction anchor rod to avoid interference between the anchoring element 104 and the anchor rod during pre-tightening.

[0092] In some embodiments, the anchor injection member 104 includes a liquid dispensing slider 1041 and a liquid guiding column 1042. The liquid dispensing slider 1041 is slidably disposed on the base 101 along the length direction of the first rotating shaft 102. The first end of the liquid guiding column 1042 is connected to the liquid dispensing slider 1041. The liquid guiding column 1042 passes through the second tube through hole 1031. The second rotating shaft 103 is rotatably connected to the liquid guiding column 1042. A fluid channel 1043 is disposed on the liquid dispensing slider 1041 and the liquid guiding column 1042.

[0093] It is understandable that during the movement of the second rotating shaft 103, the second rotating shaft 103 drives the liquid guiding column 1042 and the liquid dispensing slider 1041 to move synchronously.

[0094] Furthermore, the liquid guiding column 1042 penetrates the clearance section 212 of the first through hole 1021, and the second end (front end) of the liquid guiding column 1042 is located inside the anchor bolt section 211, so that the work of the anchor injection component 104 to deliver fluid medium into the anchor bolt (that is, the anchor injection work) is carried out inside the anchor bolt section 211.

[0095] Optionally, the fluid channel 1043 includes a vertical channel on the liquid dispensing slider 1041 and a transverse channel on the liquid guiding column 1042. The upper end of the vertical channel is the medium inlet and is located on the upper end face of the liquid dispensing slider 1041. The transverse channel extends in the front-rear direction, the lower end of the vertical channel is connected to the rear end of the transverse channel, and the front end of the transverse channel is the medium outlet and is located on the front end face of the liquid guiding column 1042.

[0096] In some embodiments, the static fluid drilling box 10 further includes a first limiting member 1032 and a second limiting member 1033, which are respectively disposed in the second pipe perforation 1031. The first limiting member 1032 and the second limiting member 1033 are respectively used to limit the displacement of the liquid guiding column 1042 in the length direction of the first rotating shaft 102.

[0097] Optionally, the liquid guiding column 1042 includes a first segment, a second segment, and a third segment connected sequentially from front to back, wherein the diameters of the first segment and the third segment are smaller than the diameter of the second segment. A first limiting member 1032 is provided on the front side of the second segment, thereby limiting the forward movement of the liquid guiding column 1042, and a second limiting member 1033 is provided on the rear side of the second segment, thereby limiting the backward movement of the liquid guiding column 1042.

[0098] Specifically, both the first limiting member 1032 and the second limiting member 1033 are bearings. The first limiting member 1032 and the second limiting member 1033 are sleeved on the liquid guiding column 1042, and the second tube through hole 1031 has steps and protrusions for securing the first limiting member 1032 and the second limiting member 1033, thereby realizing a rotatable connection between the second rotating shaft 103 and the liquid guiding column 1042.

[0099] In some embodiments, the static fluid drilling box 10 further includes a limiting slide bar 1011, the liquid dispensing slider 1041 is provided with a limiting hole, the limiting slide bar 1011 is provided on the base 101 and passes through the limiting hole, and the limiting slide bar 1011 is used to limit the rotation of the anchor injection member 104.

[0100] Optionally, the central axis of the limiting hole is not coaxial with the central axis of the first rotating shaft 102, the limiting slide rod 1011 is arranged in the front-back direction, and the limiting hole extends in the front-back direction. The limiting slide rod 1011 passes through the limiting hole so that the liquid dispensing slider 1041 can slide along the length direction of the limiting slide rod 1011 and plays a role in limiting the rotation of the liquid dispensing slider 1041.

[0101] In some embodiments, there are multiple limiting slide rods 1011 and limiting holes, and they correspond one-to-one. The multiple limiting slide rods 1011 are distributed at intervals around the liquid guiding column 1042.

[0102] Specifically, there are four limiting slide rods 1011 and four limiting holes, with the four limiting holes located at the four corners of the liquid dispensing slider 1041. Furthermore, the four limiting slide rods 1011 also serve to support the anchor injection component 104.

[0103] In some embodiments, the housing 10 further includes an anchor bolt adapter 107, which is detachably connected to the first rotating shaft 102. The anchor bolt adapter 107 is provided with a mounting hole 1071 that matches the anchor bolt, and the central axis of the mounting hole 1071 is coaxial with the central axis of the first through hole 1021.

[0104] Optionally, such as Figures 1 to 6 As shown, the anchor bolt adapter 107 is located at the front end of the first rotating shaft 102. Both the anchor bolt adapter 107 and the first rotating shaft 102 have corresponding screw holes so that they can be detachably connected, thereby facilitating replacement.

[0105] In some embodiments, the drive member 105 is a hydraulic motor, and the transmission member 106 includes a first gear 1061 and a second gear 1062 that mesh with each other. The first gear 1061 is sleeved on the output shaft of the drive member 105, and the second gear 1062 is sleeved on the first rotating shaft 102.

[0106] It is understandable that when the output shaft of the hydraulic motor rotates forward, it drives the first gear 1061 to rotate forward, which in turn drives the second gear 1062 to rotate in reverse, thereby driving the first shaft 102 to rotate in reverse. Similarly, when the output shaft of the hydraulic motor rotates in reverse, it drives the first gear 1061 to rotate in reverse, which in turn drives the second gear 1062 to rotate forward, thereby driving the first shaft 102 to rotate forward.

[0107] Therefore, the statically stable fluid drilling box 10 has the following motion characteristics:

[0108] Under the action of the first limiting member 1032, the anchoring member 104 can only rotate relative to the second rotating shaft 103 and cannot translate relative to the second rotating shaft 103 along its length. That is, when the second rotating shaft 103 translates relative to the surrounding environment, the second rotating shaft 103 drives the anchoring member 104 to translate together. When the second rotating shaft 103 rotates relative to the surrounding environment, under the action of the limiting slide rod 1011, the anchoring member 104 remains stationary relative to the surrounding environment.

[0109] During the drilling stage, the first rotating shaft 102 rotates under the drive of the driving component 105 and the transmission component 106, thereby driving the anchor bolt adapter 107 to transmit power to the anchor bolt for drilling. During this process, the internal and external threads are fully engaged, and the first rotating shaft 102 drives the second rotating shaft 103 to rotate forward together. Based on the aforementioned motion characteristics, the anchoring component 104 does not rotate with the second rotating shaft 103, but remains stationary relative to its surroundings; that is, the fluid channel 1043 is stationary relative to its surroundings. If the internal and external threads are not fully engaged, under the action of the threaded pair, the first rotating shaft 102 drives the second rotating shaft 103 to translate relative to its surroundings, and the anchoring component 104 also translates relative to its surroundings until the threads are fully engaged. Then, the second rotating shaft 103 rotates synchronously with the first rotating shaft 102, and the anchoring component 104 remains stationary relative to its surroundings. Therefore, during the entire drilling process, the anchor 104 does not rotate relative to the surrounding environment and will not cause violent shaking of the fluid medium being transported therein.

[0110] During the anchoring stage, an external medium source is delivered to the space between the anchor bolt and the surrounding rock through fluid channel 1043 to anchor the anchor bolt to the surrounding rock.

[0111] During the pre-tightening stage, the threads are initially fully engaged, and the first rotating shaft 102 rotates in the opposite direction. Under the action of the threaded pair, the first rotating shaft 102 drives the second rotating shaft 103 to move relative to the surrounding environment, leaving space for the anchor bolt pre-tightening and preventing the anchor bolt from being squeezed by the anchoring component 104 during pre-tightening. The threads gradually change from fully engaged to partially engaged until the pre-tightening of the anchor bolt is completed.

[0112] In some embodiments, the drill frame 31 further includes a top plate 33, the upper end of the support slide column 312 is connected to the top plate 33, and the top plate 33 is provided with a positioning hole 331. During the operation of the anchor drilling machine, the support slide column 312 first slides upward along the first through hole until the top plate 33 abuts against the surrounding rock. Then, the static fluid drill box 10, in conjunction with the stage stroke slide column 321, drives the drill rod or anchor rod through the positioning hole 331 to drill or anchor the surrounding rock.

[0113] In some embodiments, the drilling rig 3 further includes a support cylinder 34. One end of the cylinder body of the support cylinder 34 is connected to the frame 311, and one end of the piston rod of the support cylinder 34 is connected to the top plate 33. Since the top plate 33 is connected to the upper end of the support slide column 312, the piston rod of the support cylinder 34 extends and retracts along the cylinder body, which can drive the support slide column 312 to rise or fall along the frame 311, thereby adjusting the position of the top plate 33.

[0114] In some embodiments, the stroke slide 321 includes a primary stroke slide 3211 and a secondary stroke slide 3212. The primary stroke slide 3211 and the secondary stroke slide 3212 are connected and parallel to each other. The primary stroke slide 3211 is slidable along the second through hole. The static fluid drilling box 10 is connected to the secondary stroke slide 3212 and is slidable along the secondary stroke slide 3212.

[0115] First, the primary stroke slide column 3211 can slide along the second through hole. Simultaneously, the primary stroke slide column 3211 moves the secondary stroke slide column 3212 and the static fluid drill box 10, allowing the static fluid drill box 10 to move within its primary stroke. Furthermore, the static fluid drill box 10 can slide along the secondary stroke slide column 3212, allowing it to move within its secondary stroke. The cooperation of the primary stroke slide column 3211 and the secondary stroke slide column 3212 significantly increases the maximum stroke of the static fluid drill box 10, enabling it to drill longer boreholes. In practical applications, the maximum stroke of the drilling rig 3 can reach 2.6 meters. This allows for the one-time construction of a full-length anchor bolt, greatly improving the efficiency of anchor bolt support.

[0116] The frame 311 includes a vertical plate 3111, a first horizontal plate 3112, and a second horizontal plate 3113. The second horizontal plate 3113 is located at the bottom end of the vertical plate 3111. The upper ends of the first-stage stroke slide column 3211 and the second-stage stroke slide column 3212 are both connected to the first horizontal plate 3112, and the lower ends of the first-stage stroke slide column 3211 and the second-stage stroke slide column 3212 are connected. It can be understood that both the first horizontal plate 3112 and the second horizontal plate 3113 are perpendicular to the vertical plate 3111. The second horizontal plate 3113 is connected to the bottom end of the vertical plate 3111, while the first horizontal plate 3112 is not connected to the vertical plate 3111.

[0117] With this configuration, when the first-stage stroke slide column 3211 slides along the first through hole, it can drive the second-stage stroke slide column 3212 to move simultaneously. The function of the second horizontal plate 3113 is described below.

[0118] Furthermore, the frame 311 also includes a first connector 3114 and a second connector 3115. The first connector 3114 is located at the top of the vertical plate 3111. The first through hole and the second through hole are both located on the first connector 3114. The lower ends of the first-stage stroke slide column 3211 and the second-stage stroke slide column 3212 are both connected to the second connector 3115.

[0119] The first connecting member 3114 has a first through hole and a second through hole, and the first connecting member 3114 is connected to the top of the vertical plate 3111. The first-stage stroke slide 3211 passes through the second through hole of the first connecting member 3114. The structure of the second connecting member 3115 is similar to that of the first connecting member 3114, and it also has a through hole. The lower ends of the first-stage stroke slide 3211 and the second-stage stroke slide 3212 pass through the through hole on the second connecting member 3115 and are threaded to the nut. Thus, the lower ends of the first-stage stroke slide 3211 and the second-stage stroke slide 3212 are connected through the second connecting member 3115. The upper ends of the first-stage stroke slide 3211 and the second-stage stroke slide 3212 are both connected to the first horizontal plate 3112, and the connection between the first-stage stroke slide 3211 and the second-stage stroke slide 3212 is more stable.

[0120] The drilling rig 3 also includes a first-stage stroke cylinder 35 and a second-stage stroke cylinder 36. One end of the cylinder body of the first-stage stroke cylinder 35 is connected to the second horizontal plate 3113, and one end of the piston rod of the first-stage stroke cylinder 35 is connected to the first horizontal plate 3112. The second horizontal plate 3113 is used to support the first-stage stroke cylinder 35. The piston rod of the first-stage stroke cylinder 35 extends and retracts along the cylinder body, which can drive the first horizontal plate 3112 to rise or fall. At the same time, since the upper ends of the first-stage stroke slide column 3211 and the second-stage stroke slide column 3212 are both connected to the first horizontal plate 3112, the first-stage stroke slide column 3211 and the second-stage stroke slide column 3212 are driven to rise or fall simultaneously along the second through hole.

[0121] One end of the piston rod of the second-stage stroke cylinder 36 is connected to the static fluid drilling box 10, and one end of the cylinder body of the second-stage stroke cylinder 36 is connected to the first horizontal plate 3112 or the second horizontal plate 3113. Thus, the piston rod of the second-stage stroke cylinder 36 can drive the static fluid drilling box 10 to rise or fall along the second-stage stroke slide column 3212 by extending and retracting along the cylinder body.

[0122] It should be noted that in some embodiments, a movable pulley assembly can be added to the secondary stroke cylinder 36 to increase the maximum stroke of the static fluid drilling box 10. Specifically, the cylinder body of the secondary stroke cylinder 36 is connected to the second horizontal plate 3113. A movable pulley is installed at one end of the piston rod of the secondary stroke cylinder 36, and one end of a chain or steel cable is connected to the static fluid drilling box 10, while the other end passes around the movable pulley and is connected to the cylinder body of the secondary stroke cylinder 36. This configuration can double the stroke of the secondary stroke cylinder 36, thereby further increasing the maximum stroke of the anchor drilling rig.

[0123] There are two support slides 312, two first-stage stroke slides 3211, and two second-stage stroke slides 3212. The two support slides 312 are arranged at intervals along the width direction of the drill frame 31, the two first-stage stroke slides 3211 are arranged at intervals along the width direction of the drill frame 31, and the two second-stage stroke slides 3212 are arranged at intervals along the width direction of the drill frame 31. This can increase the structural strength of the drill frame 31 and the stroke slides 321.

[0124] In some embodiments, the bolt drilling rig used for coal roadway borehole support also includes a top mesh device 9, which is used to lay a steel mesh and place the steel mesh on the surrounding rock at the top of the roadway to prevent falling rocks from injuring workers.

[0125] Specifically, the top mesh device 9 includes a lifting column 91, a sliding column 92, and a support plate 93. The length of the lifting column 91 is adjustable. One end of the lifting column 91 is rotatably connected to the vehicle body 1, and the other end of the lifting column 91 is connected to the sliding column 92. The length of the sliding column 92 is adjustable along the width direction of the vehicle body 1. The support plate 93 is located at both ends of the sliding column 92. In use, the position of the sliding column 92 is adjusted by rotating the lifting column 91 and adjusting its length, so that the support plate 93 located at both ends of the sliding column 92 abuts against the surrounding rock. The length of the sliding column 92 can also be adjusted according to the width of the tunnel, thereby laying the steel mesh on the top of the tunnel.

[0126] In some embodiments, the walking device 6 is located below the vehicle body 1, and the walking device 6 is preferably a track wheel set.

[0127] Tracked wheel sets include tracks and wheelsets that drive the tracks forward. Each wheelset includes a drive sprocket, an idler sprocket, and a trailing sprocket. Power is supplied to the wheelset via a power unit 7. Tracked wheel sets are characterized by high driving force, low contact pressure, good off-road performance and stability, high climbing ability, small turning radius, and good maneuverability.

[0128] The bolt drilling rig used for coal roadway borehole support also includes a clearing plate, which is rotatably connected to the vehicle body 1. The angle of the clearing device can be adjusted by a hydraulic cylinder. The clearing plate is located in front of the traveling device 6 and is inclined towards the rear end of the vehicle body 1 from bottom to top. When there is loose coal in the roadway that has not been cleaned, the clearing mechanism can remove the obstacle as the drilling rig moves forward, clearing a relatively flat traveling path for the traveling device 6.

[0129] In some embodiments, the rock bolt drilling rig for coal roadway borehole support further includes an operating platform 4 and a canopy 5. The operating platform 4 is detachably connected to the robotic arm assembly 2, and the canopy 5 is connected to the robotic arm assembly 2. The operating platform 4 is adjacent to the drilling rig 3, and the canopy 5 is located above the operating platform 4. The height of the canopy 5 is adjustable. The operating platform 4 is used for workers to step on, and the canopy 5 provides protection against falling objects from the top of the roadway wall, thus improving the safety of the rock bolt drilling rig. The adjustable height of the canopy 5 allows it to accommodate operators of different heights.

[0130] The operating platform 4 is detachably connected to the robotic arm assembly 2. When the anchor bolt drilling rig needs to be moved, the operating platform 4 can be detached. When the anchor bolt or drill rod needs to be replaced, it can be installed back onto the robotic arm assembly 2. This will not affect the movement of the anchor bolt drilling rig and ensures the anchor bolt support efficiency of the anchor bolt drilling rig in the roadway.

[0131] The operating platform 4 includes a first connecting rod 44 and a first pedal 41. The upper end of the first connecting rod 44 is detachably connected to the robotic arm assembly 2, and the lower end of the first connecting rod 44 is connected to the first pedal 41.

[0132] Optionally, the upper end of the first connecting rod 44 is bolted to the robotic arm assembly 2. Specifically, the first connecting rod 44 has a through hole, and the robotic arm assembly 2 has a threaded hole. The bolt passes through the through hole in the first connecting rod 44 and engages with the threaded connection in the robotic arm assembly 2, thereby detachably connecting the first connecting rod 44 and the robotic arm assembly 2. The lower end of the first connecting rod 44 can be detachably connected to the first pedal 41, or it can be non-detachably connected, as long as sufficient connection strength is ensured.

[0133] The operating platform 4 also includes a second pedal 42, which is flip-able with the first pedal 41 between a first position and a second position. In the first position, the second pedal 42 is located on one side of the first pedal 41 in the width direction of the vehicle body 1, and in the second position, the second pedal 42 is perpendicular to the first pedal 41.

[0134] The second pedal 42 is used to increase the stepping area of ​​the operating platform 4 to facilitate the operation of workers. The second pedal 42 is connected to the first pedal 41 in the width direction of the vehicle body 1. With this arrangement, the first pedal 41 can be set at a position not exceeding the sides of the vehicle body 1. When the second pedal 42 is in the first position, it extends beyond the sides of the vehicle body 1. When the anchor drilling rig needs to be moved, the second pedal 42 can be rotated to the second position, where the second pedal 42 is perpendicular to the first pedal 41. At this time, both the second pedal 42 and the first pedal 41 extend beyond the sides of the vehicle body 1, and the anchor drilling rig can move normally.

[0135] Furthermore, the operating platform 4 also includes a third pedal 43, which is rotatably connected to the second pedal 42, and the third pedal 43 can be flipped between a third position and a fourth position. In the third position, the third pedal 43 is located on one side of the second pedal 42 in the length direction of the vehicle body 1, and in the fourth position, the third pedal 43 is stacked on top of the second pedal 42.

[0136] Similarly, the third pedal 43 can further increase the area of ​​the operating platform 4, and the third pedal 43 and the second pedal 42 are connected in the length direction of the vehicle body 1. When the operator changes the drill rod or anchor rod, the third pedal 43 is rotated to the first position. When it is necessary to move the drilling rig, the third pedal 43 is first rotated to the second position so that it overlaps with the second pedal 42, and then the second pedal 42 is rotated to the second position. At this time, the third pedal 43 and the second pedal 42 are both perpendicular to the first pedal 41 and do not exceed the two sides in the width direction of the vehicle body 1, so that the anchor rod drilling rig can move normally.

[0137] In some embodiments, the operating platform 4 further includes a fence 45, which is detachably connected to at least one of the first pedal 41, the second pedal 42, and the third pedal 43. The fence 45 surrounds the outside of the first pedal 41, the second pedal 42, and the third pedal 43. The fence 45 serves a protective function to prevent workers from falling off the anchor drilling rig during operation. The fence 45 is detachably connected to at least one of the three pedals. When workers are working on the operating platform 4, the fence 45 needs to be installed first. When it is necessary to fold the pedals or remove them from the anchor drilling rig, the fence 45 can be removed.

[0138] Specifically, at least one of the first pedal 41, the second pedal 42, and the third pedal 43 is provided with a fourth connector 46 on its periphery. The fourth connector 46 has a through hole with the opening direction of the through hole being vertical. The fence 45 includes multiple connecting pipes 451 and limiting members 452 provided on the connecting pipes 451. The connecting pipes 451 are inserted into the through hole of the fourth connector 46, and the limiting members 452 are locked at the top of the fourth connector 46.

[0139] Understandably, the fence 45 features a quick-connect design. During installation, simply insert the connecting pipe 451 of the fence 45 into the through hole of the fourth connector 46. The limiting member 452 prevents the fence 45 from being positioned too low. This quick-connect design saves time on the installation and disassembly of the fence 45, improving the working efficiency of the anchor drilling rig.

[0140] In some embodiments, the rock bolt drilling rig for coal roadway borehole support also includes a cable reel device 8, which is a cylindrical component and is rotatably disposed at the rear end of the vehicle body 1 for reeling in and unelevating the cable during the forward and backward movement of the rock bolt drilling rig.

[0141] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to 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 invention.

[0142] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
