Description

Technical Field

[0001] This invention relates to the field of rapid underground tunneling and support equipment technology in coal mines, and in particular to a compact five-arm anchor bolt and cable drilling rig. Background Technology

[0002] After the excavation of underground roadways in coal mines is completed, rock bolt support must be implemented immediately to control the deformation of the surrounding rock and prevent the collapse of the roof and sidewalls. This is a core process to ensure the continuity of mining and the safety of underground operations. Currently, underground support equipment is mainly divided into four categories: 1. Manual single-unit rock bolt drilling rigs: These rely entirely on manual lifting and positioning for drilling. Personnel are in the dangerous area of ​​an open roof for a long time. The support efficiency is extremely low, the labor intensity is high, and the risk of dust and falling rocks is prominent. They are only suitable for small-scale sporadic support. 2. Two-arm and four-arm single-roof rock bolt drilling rigs: These are equipped only with roof drilling rigs and no matching sidewall drilling rigs. Sidewall rock bolt support requires secondary manual drilling, which disconnects the excavation and support processes. The equipment needs to be moved and repositioned multiple times, which greatly slows down the excavation cycle speed. 3. Six-arm rock bolt drilling rigs: These adopt a 4-roof and 2-sidewall layout. The overall length and width of the machine are large, the turning radius is large, and the passage in narrow cross-section roadways is obstructed. The high height makes it unusable in low-lying roadways; the integrated top and side anchor mechanisms interfere with each other, preventing completely independent and synchronous operation; 4. A limited number of five-arm support devices: Existing five-arm drilling rigs generally suffer from three major defects: ① The lifting platform's four-link system is located entirely above the main body, resulting in significant height redundancy and limiting access to thin coal seams and low-lying roadways; ② The drilling rig's sliding stroke is short, insufficient for full coverage support of wide roadway roofs, preventing one-time coverage of wide roadway roofs; ③ The integrated arrangement of the top and side anchor platforms and the side anchor actuators causes severe motion interference, preventing unlimited synchronous construction of the top and side drilling rigs, requiring separate operations, resulting in prolonged support cycle times and low support efficiency. 4. The drilling rig's attitude adjustment structure is simple, with a small telescopic sliding range, poor adaptability, and inability to simultaneously achieve precise centering adjustments and large-scale coverage on both sides.

[0003] Current intelligent rapid tunneling systems for coal mines require "synchronous matching of tunneling and support," which imposes stringent requirements on support equipment, including simultaneous operation of the roof and walls, compact and low profile, wide drilling coverage, flexible attitude adjustment, and comprehensive safety protection.

[0004] Based on this, this application creates a novel compact five-arm anchor bolt and cable drilling rig with a completely new structure. It systematically innovates the overall layout, lifting and bearing mechanism, drilling rig sliding platform, top and side split execution mechanism, and graded angle adjustment, so as to meet the above-mentioned working conditions simultaneously and become a target that the industry urgently needs to improve. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a compact five-arm anchor bolt and cable drilling rig, which makes systematic innovations in terms of overall layout, lifting and bearing mechanism, drilling rig sliding platform, top and side split execution mechanism, and graded angle adjustment, so as to meet the above working conditions at the same time and overcome the shortcomings of existing anchor bolt and cable drilling rigs.

[0006] To address the aforementioned technical problems, this invention provides a compact five-arm anchor bolt and cable drilling rig, comprising a main body and three top anchor bolt drilling rigs disposed at its upper front end, and two side anchor bolt drilling rigs disposed in the middle of its upper part. The side top anchor bolt drilling rigs located on the sides are symmetrically fixed to an integrated folding mechanism.

[0007] The integrated folding mechanism includes a standing platform and a folding operating table mounted thereon, as well as a first lateral movement mechanism located on the front side of the standing platform. The side-top anchor drilling rig is connected to the first lateral movement mechanism.

[0008] The inner end of the manned platform is hinged to the fixed platform of the main body, and can be vertically folded inward and horizontally unfolded outward under the action of the platform tilting cylinder; the operating table is set on the manned platform through the swing cylinder, and can be parallel to the upper surface of the platform when folded and perpendicular to the upper surface of the platform when in use; the first transverse movement mechanism includes a first transverse movement speed-multiplying cylinder, a first sliding seat and a first drilling rig angle adjustment mechanism, one side of the first sliding seat is fixed to the chain of the first transverse movement speed-multiplying cylinder, and the other side is connected to the first drilling rig angle adjustment mechanism;

[0009] The first drilling rig angle adjustment mechanism includes a mounting plate, a rotary drive, a drive connecting seat, a drilling rig connecting seat, and a drilling rig adjustment cylinder. One side of the mounting plate is fixedly connected to the first sliding seat, and the other side is connected to the rotary drive. The drive connecting seat is connected to the rotary drive and is driven to rotate by it. The drilling rig connecting seat adopts a U-shaped structure for fixing the side-top anchor drilling rig. One end of the U-shaped structure is connected to the drive connecting seat through a pin. One end of the drilling rig adjustment cylinder is connected to the drive connecting seat, and the other end is connected to the drilling rig connecting seat. Under the action of the rotary drive, the side-top anchor drilling rig can rotate left and right to ensure that the manned platform remains vertically set in both vertically folded and horizontally unfolded states. This allows for compact folding when the drilling rig is moving and top anchor support during operation. The side-top anchor drilling rig can also adjust its front and rear angles under the action of the drilling rig adjustment cylinder, and can also move laterally by the first transverse speed-multiplying cylinder when the manned platform is horizontally unfolded.

[0010] In a further improvement, the first drilling rig angle adjustment mechanism also includes a rotation limiting mechanism. The rotation limiting mechanism includes a limiting component and a limiting block. The limiting component is disposed on the rotary disk of the drive connecting seat, and the limiting block is disposed on the mounting plate or the housing of the rotary drive. The limiting block restricts the excessive rotation of the rotary disk by abutting against the limiting component, thereby limiting the rotation angle of the drive connecting seat and realizing the left and right 95° rotation of the side-top anchor drilling rig.

[0011] In a further improvement, the platform includes an outer sleeve, an inner sleeve, and a telescopic cylinder. The outer sleeve is fitted over the inner sleeve and extends and retracts along the inner sleeve under the action of the telescopic cylinder. The operating table and the first lateral movement mechanism are both mounted on the outer sleeve.

[0012] The upper part of the inner sleeve of the platform is provided with a bearing seat that is hinged to one end of the platform tilting cylinder. The outer sleeve of the platform is provided with a clearance groove to avoid the bearing seat. The other end of the platform tilting cylinder is hinged to the fixed platform of the main body. The extension and retraction of the platform tilting cylinder can drive the inner sleeve and the outer sleeve of the platform to fold and unfold without affecting the extension and retraction of the outer sleeve of the platform.

[0013] In a further improvement, the operating platform includes a mounting base, a swing cylinder, a frame assembly, an operating valve, and a protective cover; the mounting base is fixed to the upper part of the outer sleeve of the platform, the swing cylinder is fixed to the mounting base, the frame assembly is mounted to the swing cylinder through connecting plates on both sides, the protective cover is disposed on the upper part of the frame assembly, and the operating valve is disposed inside the protective cover, so that the swing cylinder can drive the frame assembly, the operating valve, and the protective cover to swing together;

[0014] The protective cover includes a housing and an upward-flipping door on its front side. The protective cover also includes an operating valve protection mechanism, which includes a U-shaped locking rod, a locking nut, and corresponding limiting grooves on the left and right sides of the housing. Each limiting groove includes a horizontal groove and a locking groove and a release groove extending downwards from the bottom of both ends of the horizontal groove. Each locking groove and release groove includes two slots corresponding to the rod of the U-shaped locking rod. The two slots of the locking groove are located on either side of the operating handle of the operating valve. The U-shaped locking rod passes through the locking groove on one side of the housing to the locking groove on the other side and is then fixed by the locking nut, thus limiting and locking the operating handle. When the operating handle needs to be released, the U-shaped locking rod and the locking nut connected to it are moved upwards from the locking groove and into the release groove for placement when the U-shaped locking rod releases the operating handle.

[0015] In a further improvement, a lifting mechanism is provided at the upper front end of the main body. The lifting mechanism includes a lifting platform, a four-bar linkage, a front lifting cylinder, and a rear lifting cylinder. The bottom of the four-bar linkage is located in a groove at the front end of the main body, and its top is hinged to the bottom of the lifting platform. The front lifting cylinder and the rear lifting cylinder are respectively located between the lifting platform and the main body, and the lifting action of the lifting platform is realized with the four-bar linkage.

[0016] The lifting platform has its two sides hinged to the standing platforms of the integrated folding mechanism. A second lateral movement mechanism is located at the front end of the lifting platform. This second lateral movement mechanism includes a second lateral movement speed-multiplying cylinder, a second sliding seat, and a second drilling rig angle adjustment mechanism. One side of the second sliding seat is fixed to the chain of the second lateral movement speed-multiplying cylinder, and the other side is connected to the second drilling rig angle adjustment mechanism. The second drilling rig angle adjustment mechanism includes left-right angle adjustment seats, front-back angle adjustment seats, left-right adjustment cylinders, and front-back adjustment cylinders. The left-right angle adjustment seats have an L-shaped structure, and one end of the L-shaped structure is connected to the second sliding seat via a pin. The front and rear angle adjustment seat adopts a U-shaped structure of a fixed center-top anchor drilling rig. One end of the U-shaped structure is hinged to the other end of the L-shaped structure via a pin. One end of the left and right adjustment cylinder is connected to the second sliding seat, and the other end is connected to the left and right angle adjustment seat. One end of the front and rear adjustment cylinder is connected to the left and right angle adjustment seat, and the other end is connected to the center-top anchor drilling rig. Under the action of the left and right adjustment cylinder, the center-top anchor drilling rig can achieve left and right angle adjustment of ±5°, and under the action of the front and rear adjustment cylinder, it can achieve front and rear angle adjustment of ±5°. It can also move laterally under the drive of the second transverse speed-multiplying cylinder.

[0017] Further improvements include a nine-valve control panel on the lifting platform for controlling the actions of the central anchor drilling rig. The nine-valve control panel includes a control panel frame, a nine-valve assembly, a nine-valve assembly cover, and a nine-valve limit group. The control panel frame is fixed to the lifting platform, the nine-valve assembly cover is fixed to the upper part of the control panel frame, the nine-valve assembly is fixed inside the nine-valve assembly cover, and the operating handles of the nine-valve assembly extend beyond the top of the nine-valve assembly cover. The nine-valve limit group includes a limit plate and limit bolts, with nine corresponding operating handles of the nine-valve assembly located in the middle of the limit plate. The limiting hole is T-shaped, with the elongated hole of the T-shaped hole for the operating handle to perform actions, and the short hole restricting the operation of the operating handle. The limiting plate has elongated holes on both sides. The limiting bolts pass through the elongated holes to movably mount the limiting plate on the top plate of the nine-way valve assembly cover, allowing the limiting plate to move left and right. When the limiting plate moves to the right, the operating handle enters the short hole of the limiting hole, restricting its operation; when the limiting plate moves to the left, the operating handle enters the elongated hole of the limiting hole, releasing its operation.

[0018] Further improvements include a temporary support mechanism on the lifting platform. This mechanism comprises a telescopic outer sleeve, a telescopic inner sleeve, a support adjustment cylinder, a support sleeve, left and right telescopic beams, and front and rear telescopic beams. The telescopic inner sleeve extends and retracts along the telescopic outer sleeve under the action of the cylinder. The bottom of the support sleeve is hinged to the extended end of the telescopic inner sleeve. An angle adjustment cylinder is provided between the support sleeve and the telescopic inner sleeve to adjust the support angle. The left and right telescopic beams are respectively located on the left and right sides of the support sleeve and can extend and retract left and right under the action of the cylinder. The front and rear telescopic beams are respectively located in the left and right telescopic beams, and the extension positions of the front and rear telescopic beams in the left and right telescopic beams are limited by a structure of positioning pins and multiple limiting holes.

[0019] One end of the telescopic outer sleeve and the support adjustment cylinder are both hinged to the column of the lifting platform, and the other end of the support adjustment cylinder is hinged to the lower part of the other end of the telescopic outer sleeve. The extension and retraction of the support adjustment cylinder can drive the telescopic outer sleeve and the support sleeve to adjust the support height.

[0020] In a further improvement, the lifting platform is also equipped with a six-valve operating console for controlling the temporary support mechanism. The six-valve operating console includes a six-valve assembly, a six-valve assembly cover, and a six-valve limiting assembly. The six-valve assembly cover is fixed to the side of the operating console frame, the six-valve assembly is fixed inside the six-valve assembly cover, and the operating handle of the six-valve assembly extends out of the side of the six-valve assembly cover. The six-valve limiting assembly includes two fixing plates opposite to each other on both sides of the six-valve assembly cover, two limiting rods, and fixing screws fixed to both ends of the limiting rods. The two fixing plates are respectively provided with corresponding F-shaped grooves. The two horizontal grooves of the F-shaped grooves are respectively located on the upper and lower sides of the operating handle of the six-valve assembly. The two limiting rods are respectively fixed in the two horizontal grooves to limit the operation of the operating handle. When the operating handle needs to be operated, the two limiting rods are moved into the vertical grooves of the F-shaped grooves to release the operating handle.

[0021] In a further improvement, a support anchor sliding mechanism is provided in the upper middle part of the main body. The support anchor sliding mechanism includes a sliding base, a sliding guide plate, a sliding box, and a sliding drive cylinder. The sliding base is fixed on the main body, and the sliding guide plate and the sliding base together form a sliding guide. The sliding box includes a left sliding box and a right sliding box, which are slidably matched and mounted on the sliding guide. The sliding drive cylinder drives the left sliding box and the right sliding box to extend or retract to the left or right along the sliding guide.

[0022] The left and right sliding boxes are respectively equipped with anchor lifting assemblies. Each anchor lifting assembly includes an inner lifting sleeve, an outer lifting sleeve, a lifting cylinder, a speed-multiplying lifting mechanism, and a connecting seat assembly. The bottom end of the inner lifting sleeve is fixed to the left or right sliding box, and the outer lifting sleeve is located outside the inner lifting sleeve. The lifting cylinder drives the outer lifting sleeve to move up and down along the inner lifting sleeve. The speed-multiplying lifting mechanism is fixed to the outer lifting sleeve, and the connecting seat assembly is connected to the speed-multiplying lifting mechanism and can move up and down along the outer lifting sleeve. The anchor drilling rig is connected to the front side of the connecting seat assembly through a first drilling rig angle adjustment mechanism, which enables the anchor drilling rig to rotate left and right and adjust its front and rear angles. The anchor drilling rig also moves up and down under the action of the lifting cylinder and the speed-multiplying lifting mechanism.

[0023] In a further improvement, the outer side of the connecting seat assembly is also connected to the anchor tilting platform, and the rear side of the connecting seat assembly is also connected to the anchor operating platform.

[0024] The upper rear end of the main body is provided with an oil tank, an electric motor oil pump, a cover plate, an electrical system, a cable winding section, a mounting frame assembly, a hydraulic system, and a water system;

[0025] The bottom of the main body is connected to the walking part, the lower front end of the main body is connected to the shovel plate part, and the lower rear end of the main body is connected to two support leg assemblies respectively.

[0026] The width of the five-arm anchor bolt and cable drilling rig is 2 meters when it is retracted.

[0027] With this design, the present invention has at least the following advantages:

[0028] 1. This invention relates to a compact five-arm anchor bolt and cable drilling rig. It employs an integrated folding mechanism to mount two side-mounted anchor bolt drilling rigs, and a side-mounted anchor bolt drilling rig to mount two side-mounted anchor bolt drilling rigs using a side-mounted sliding mechanism. This design results in a small, compact size in its retracted state, with a width of only 2 meters. During operation, all five drilling arms can work simultaneously, improving efficiency and enabling anchor bolt and cable support up to 6.5 meters in width. In contrast, similar wide-body anchor bolt drilling rigs are only suitable for continuous mining and dual-roadway excavation processes. This equipment solves the problem of insufficient roof support in wide roadways and addresses the issues of poor maneuverability and inconvenient relocation in narrow roadways, making it applicable to a wider range of construction techniques. Furthermore, when the two side-mounted anchor bolt drilling rigs are extended to a horizontal position on the work platform, they can be synchronously rotated via an electrical system to maintain a vertical position, improving efficiency, reducing operational difficulty, and allowing the drilling rig to be used with various excavation processes. This enhances mechanization, simplifies operation, frees up labor, and improves safety and efficiency.

[0029] 2. Furthermore, the lifting mechanism reduces the height of the drilling rig to only 2.8 meters, effectively solving the problems of traditional four-link lifting systems occupying too much vertical space, having a large overall height, and poor passageway capability in low-ceilinged roadways. The drilling rig angle adjustment mechanism also addresses the issue of a single drilling rig attitude adjustment mode, which cannot simultaneously achieve small-scale centering adjustments and large-scale rotational alignment on both sides. Finally, the retractable personnel platform solves the problems of lacking a retractable safety platform, inadequate protection for personnel working at height, and the space occupied during site transfers.

[0030] 3. Furthermore, the foldable operating table allows the platform to be folded horizontally when it is in the retracted state, reducing space occupation; during operation, the operating table can be flipped vertically to the platform for easy operation.

[0031] 4. Furthermore, by setting up the operating valve limit group and the six-way valve limit group, the limit rod can be moved in parallel to cleverly restrict and release the operating handle. This is simple, convenient, safe, and effective, preventing accidental operation. Additionally, the T-hole in the nine-way valve limit group and the elongated hole in the limit plate cleverly achieve the cooperation between the limit plate and the operating handle, satisfying the requirements for limiting and releasing the operating handle. This is scientific, reasonable, simple, and efficient.

[0032] 5. Furthermore, the addition of a sliding and lifting mechanism for the side anchoring allows the side anchor drilling rig to extend laterally and move vertically, meeting its anchoring needs and enabling synchronous operation with the top anchor drilling rig without interference, thus improving support efficiency. This invention's compact five-arm anchor bolt and cable drilling rig meets the requirements of "synchronous matching of tunneling and support," achieving the overall effects of simultaneous top and side anchoring operations, a compact and low profile, a wide drilling coverage area, flexible posture adjustment, and comprehensive safety protection.

[0060] See attached document Figures 3 to 5 As shown, in this embodiment, a lifting mechanism 130 is also provided at the upper front end of the main body 10. The lifting mechanism 130 includes a lifting platform 131, a four-bar linkage 132, a front lifting cylinder 133, and a rear lifting cylinder 134. The bottom of the four-bar linkage 132 is disposed in a groove 103 at the front end of the main body 10, and its top is hinged to the bottom of the lifting platform 131. The front lifting cylinder 133 and the rear lifting cylinder 134 are respectively disposed between the lifting platform 131 and the main body 10, and together with the four-bar linkage 132, the lifting platform 131 is lifted, achieving a 1000mm lift, which is stable and reliable.

[0061] For details, see attached. Figure 2 As shown, the three top anchor drilling machines include two parts: a side top anchor drilling machine 101 located on the side and a middle top anchor drilling machine 102 located in the middle, both of which are mounted on the lifting platform 131.

[0062] Among them, the side-mounted anchor drilling rigs 101 are symmetrically fixed on the integrated folding mechanism 1, forming a modular folding structure. (See attached diagram) Figures 6 to 9As shown, the integrated folding mechanism 1 includes a standing platform 11 and a folding operating table 12 mounted thereon, as well as a first transverse movement mechanism 14 located on the front side of the standing platform 11. The side-mounted anchor drilling rig 101 is connected to the first transverse movement mechanism 14. The inner end of the standing platform 11 is hinged to the side of the lifting platform 131, enabling it to fold vertically inward and unfold horizontally outward under the action of the platform tilting cylinder 13. The operating table 12 is mounted on the standing platform 11 via a swing cylinder, allowing it to be parallel to the upper surface of the platform when folded and perpendicular to the upper surface of the platform when in use. The first transverse movement mechanism 14 includes a first transverse speed-multiplying cylinder 141, a first sliding seat 142, and a first drilling rig angle adjustment mechanism. One side of the first sliding seat 142 is fixed to the chain of the first transverse speed-multiplying cylinder 141, and the other side is connected to the first drilling rig angle adjustment mechanism.

[0063] See attached document Figure 10 and 11 As shown, in this embodiment, the first drilling rig angle adjustment mechanism includes a mounting plate 143, a rotary drive 144, a drive connecting seat 145, a drilling rig connecting seat 146, and a drilling rig adjustment cylinder 147. One side of the mounting plate 143 is fixedly connected to the first sliding seat 142, and the other side is connected to the rotary drive 144. The drive connecting seat 145 is connected to the rotary drive 144 and is driven by it to rotate, achieving a 95° rotation from vertical to horizontal. The drilling rig connecting seat 146 adopts a U-shaped structure for fixing the side-top anchor drilling rig 101.

One end of the drilling rig adjusting cylinder 147 is connected to the drive connecting seat 145, and the other end is connected to the drilling rig connecting seat 146. Under the action of the rotary drive 144, the side-top anchor drilling rig 101 rotates left and right to ensure that the manned platform 11 remains vertically set in both vertically folded and horizontally unfolded states, achieving a compact folding when the drilling rig is moving and completing top anchor support during operation. The side-top anchor drilling rig 101 can also achieve a front-to-back angle adjustment of ±5° under the action of the drilling rig adjusting cylinder 147, and can also move laterally by the first transverse speed multiplier cylinder 141 when the manned platform 11 is horizontally unfolded, achieving a left-to-right stroke movement of 840mm.

[0064] Preferably, the first drilling rig angle adjustment mechanism further includes a rotation limiting mechanism 148. The rotation limiting mechanism 148 includes a limiting member 1481 and a limiting block 1482. The limiting member 1481 is disposed on the rotary disk of the drive connecting seat 145, and the limiting block 1482 is disposed on the mounting plate 143 or the housing of the rotary drive 144. The limiting block 1482, by abutting against the limiting member 1481, restricts the excessive rotation of the rotary disk, thereby limiting the rotation angle of the drive connecting seat 145, and realizing a 95° left-right rotation of the side-top anchor drilling rig 101.

[0065] Even better, as shown in the appendix Figure 8 and 9 As shown, the standing platform 11 also includes a platform outer sleeve 111, a platform inner sleeve 112, and a platform telescopic cylinder 113. The platform outer sleeve 111 is fitted outside the platform inner sleeve 112 and, under the action of the platform telescopic cylinder 113, extends and retracts 600mm along the platform inner sleeve 112, expanding the area of ​​the standing platform. The operating table 12 and the first lateral movement mechanism 14 are both mounted on the platform outer sleeve 111. The upper part of the platform inner sleeve 112 is provided with a bearing seat 1121 hinged to one end of the platform tilting cylinder 13. The platform outer sleeve 111 is provided with a clearance groove 1111 to avoid the bearing seat 1121. The other end of the platform tilting cylinder 13 is hinged to the lifting platform 131. The extension and retraction of the platform tilting cylinder 13 can drive the platform inner sleeve 112 and the platform outer sleeve 111 to fold and unfold without affecting the extension and retraction of the platform outer sleeve 111.

The limiting plate 1641 also has elongated holes 1644 on both sides. The limiting bolts 1642 pass through... The elongated hole 1644 allows the limiting plate 1643 to be movably mounted on the top plate of the nine-valve assembly cover 163, and enables the limiting plate 1643 to move left and right. When the limiting plate 1643 moves to the right, the operating handle enters the short hole of the limiting hole 1643, restricting the operation of the operating handle; when the limiting plate 1643 moves to the left, the operating handle enters the long hole of the limiting hole 1643, releasing the operating handle of the nine-valve assembly 162.

[0070] See attached document Figure 15 and 16 As shown, the lifting platform 131 is also equipped with a temporary support mechanism 17.

When the operating handle needs to be operated, the two limiting rods 185 are moved into the vertical grooves 188 of the F-shaped grooves to release the operating handle of the six-valve assembly 181. Even better, the transverse groove 187 is set to tilt downward at a certain angle, which can more stably ensure the safety of the limit position.

[0073] See attached document Figure 1 and 17 As shown, in this embodiment, the upper middle part of the main body 10 is provided with a support anchor sliding mechanism 19. The support anchor sliding mechanism 19 includes a sliding base 191, a sliding guide plate 192, a sliding box 193, and a sliding drive cylinder 194.

The sliding box 193 includes a left sliding box and a right sliding box, which are slidably matched and assembled on the sliding guide 192. The sliding drive cylinder 194 drives the left sliding box and the right sliding box to extend or retract to the left or right along the sliding guide, so as to slide outward by 550mm.

[0074] See attached document Figures 18 to 20As shown, anchor lifting assemblies 21 are respectively installed on the left and right sliding boxes. Each anchor lifting assembly 21 includes an inner lifting sleeve 211, an outer lifting sleeve 212, a lifting cylinder 213, a speed-multiplying lifting mechanism 214, and a connecting seat assembly 215.

The lifting mechanism 214 is connected by a chain and can move up and down along the lifting outer sleeve 212. That is, the connecting seat group 215 can complete two-stage lifting on the guide column of the lifting outer sleeve 212, achieving an upward movement stroke of 2550mm. The anchor bolt drilling machine 201 is connected to the front side of the connecting seat group 215 through the first drilling machine angle adjustment mechanism, realizing the left and right rotation and front and back angle adjustment of the anchor bolt drilling machine 201. The anchor bolt drilling machine 201 also moves up and down under the action of the lifting cylinder 213 and the speed-multiplying lifting mechanism 214.

[0075] The anchor lifting assembly 21 is also connected to the anchor operating platform 217. (See attached image) Figure 20 and 21 As shown, the anchoring control panel 217 includes: a connecting bracket 2171, an operating valve group 2172, a pressure gauge group 2173, and an emergency stop group 2174. The anchoring control panel 217 is divided into two operating panels. One adjustment operation panel is fixed to the rear area of ​​the connecting seat group 215 via the connecting bracket 2171, and the other drilling operation panel is fixed to the frame of the anchoring drill rig 201 via the connecting bracket 2171. The operating valve group 2172 of the adjustment operation panel integrates sliding control, lifting control, angle adjustment control, and platform folding control. The operating valve group of the drilling operation panel integrates drill feed control, drilling motor control, and drill rod clamping control. The pressure gauge group 2173 and the emergency stop group 2174 are also integrated on the anchoring control panel 217. The structure of the operating valve limit group of the anchoring control panel 217 is the same as that of the nine-way valve limit group 164, and it also uses T-holes to limit and release the operating handle.

[0076] As attached Figure 1 and 2 As shown, the outer side of the connecting seat assembly 215 is also connected to the anchor tilting platform 216. (See attached diagram.) Figure 22 and 23As shown, the anchor-supporting tilting platform 216 includes: a protective railing 2161, a platform base plate 2162, a tilting cylinder 2163, and a tilting connecting seat 2164; the tilting connecting seat 2164 is fixed to the side of the connecting seat assembly 215 by bolts, one end of the platform base plate 2162 is connected to the tilting connecting seat 2164 by a pin, and both ends of the tilting cylinder 2163 are respectively connected to the tilting connecting seat 2164 and the platform base plate 2162; when the tilting cylinder 2163 extends, the platform base plate 2162 tilts outward to form a personnel-carrying work platform; when the tilting cylinder 2163 retracts, the platform base plate 2162 folds inward to fit against the tilting connecting seat 2164 to achieve folding; the platform base plate 2162 is equipped with a protective railing 2161 around its perimeter, and the protective railing 2161 folds together with the platform base plate 2162 to prevent the risk of personnel falling.

[0077] See attached document Figure 24 As shown, in this embodiment, the side-top anchor drilling machine 101, the middle-top anchor drilling machine 102, and the side anchor drilling machine 201 have the same structure, all including: a rotary mechanism 1001, a speed doubling mechanism 1002, a propulsion cylinder 1003, a frame assembly 1004, a slide mechanism 1005, a top support mechanism 1006, and a clamping mechanism 1007. The slewing mechanism 1001 is bolted to the guide post of the carriage mechanism 1005 and can slide along the guide post. The slewing mechanism 1001 is bolted and mounted on the chain of the speed-increasing mechanism 1002. As the hydraulic cylinder in the speed-increasing mechanism 1002 extends or retracts, it drives the slewing mechanism 1001 to slide along the guide post. One end of the speed-increasing mechanism 1002 is bolted to the upright plate of the carriage mechanism 1005, and the other end is a chain tensioning mechanism. The extension or retraction of the hydraulic cylinder in the speed-increasing mechanism 1002 drives the chain on it to rotate. The carriage mechanism 1005 is bolted to the upper fixed seat of the frame assembly 1004 and can slide along the guide post. One end of the propulsion cylinder 1003 is bolted to the upright plate of the frame assembly 1004, and the other end is bolted to the carriage mechanism 1005. On the 005 vertical plate, the extension and retraction of the hydraulic cylinder 1003 in the propulsion cylinder can drive the guide column in the slide mechanism 1005 to slide back and forth along the upper fixed seat in the frame assembly 1004; the top support mechanism 1006 is installed on the lower fixed seat in the frame assembly 1004 through the guide column and can slide along the guide column. One end of the telescopic hydraulic cylinder in the top support mechanism 1006 is installed on the vertical plate of the frame assembly 1004 through the pin. The extension and retraction of the hydraulic cylinder can drive the guide column in the top support mechanism 1006 to slide back and forth along the lower fixed seat in the frame assembly 1004; the clamping mechanism 1007 is fixed to the vertical plate of the top support mechanism 1006 by bolts. The extension and retraction of the clamping hydraulic cylinder in the clamping mechanism 1007 pushes the clamping block to move, which can assist the operator in disassembling the drill rod, reducing the labor intensity and improving the work efficiency. Furthermore, the drilling rig can provide a large locking torque, and the anchor rods drilled by this drilling rig do not need to be tightened again, resulting in an extremely low anchor loss rate.

[0078] Furthermore, in this embodiment, the walking unit 20 is bolted to the lower part of the main body 10 and is a tracked heavy-duty walking unit that can be manually or remotely controlled. The outrigger assembly 40 is bolted to the lower part of the main body 10 and to the front and rear of the walking unit 20. When the drilling rig is moving, the outrigger cylinders in the outrigger assembly 40 retract to increase the ground clearance without affecting movement. When the drilling rig is moving, the outrigger cylinders in the outrigger assembly 40 extend to support the base plate, increasing the stability of the drilling rig. The shovel plate part 30 consists of a telescopic cylinder and a shovel plate frame, which is bolted to the front of the main body 10. The telescopic cylinder is connected to the main body 10 at one end via a pin and to the shovel plate frame at the other end. The extension and retraction of the cylinder causes the shovel plate frame to rise or support the ground. The shovel plate part 30 can stabilize the drilling rig during operation and can also lift and clear loose coal in the roadway when the drilling rig is moving.

[0079] In this embodiment, all hydraulic lines of the drilling rig are integrated, eliminating pipe pulling and interference during lifting and sliding. Specifically, the oil tank 50 is bolted to the upper center of the main body 10, storing hydraulic oil for the actuators and serving as the primary mounting location for electrical components; the motor pump 60 is bolted to the upper rear center of the main body 10; the cover plate 70 is bolted to the upper rear center of the main body 10, providing added protection and also serving as a primary mounting location for electrical components; the cable reel 90 is bolted to the upper rear center of the main body 10, primarily for cable reeling, reducing worker workload; and the mounting frame 100 is bolted to the upper rear center of the main body 10, serving as the primary mounting location for electrical components.

[0080] This invention employs full hydraulic control, ensuring a stable and reliable hydraulic system. Each operating valve has an operation indicator, making operation simple and easy to understand. The hydraulic system 110 is connected to at least one of the aforementioned actuators and provides power to at least one of them. The electrical system 80 is connected to at least one of the aforementioned actuators and provides signals to at least one of them. The electrical system 80 of this invention has explosion-proof functionality, and all components comprising the electrical system 80 possess explosion-proof certification and coal mine safety certification, ensuring the safety of operators during drilling rig operation. The water system 120 is connected to at least one of the aforementioned actuators and supplies water to at least one of them.

[0081] Furthermore, in this embodiment, the movements of the walking unit 20, the shovel plate unit 30, the lifting platform 131, the cable reel unit 90, the outrigger assembly 40, and the side-top anchoring platform 11 can all be remotely controlled, which increases operational safety, reduces construction risks, and achieves the effect of reducing manpower and increasing efficiency.

[0082] Based on the above embodiments, the five-arm anchor bolt and anchor cable drilling rig has the following external dimensions when it is in the retracted state: 6400mm long, 2000mm wide, and 2800mm high. When the anchor bolt drilling rig is working, it can cover a range of 6500mm and can tilt forward and backward by ±5°. Both side-top anchor bolt drilling rigs can swing left and right by 95°, which meets the requirements of anchor bolt and anchor cable support.

[0083] When the drilling rig reaches the working position to carry out anchor bolt support construction, the top anchor worker walks to the front of the oil tank section 50 and operates the control valve group to make the side top anchor personnel platforms 11 on both sides extend horizontally outward. At the same time, the two side top anchor drilling rigs 101 rotate synchronously through the electrical system control, always maintaining a vertical state. The worker climbs onto the machine through the ladder inside the side top anchor personnel platform 11, enters the lifting platform 131 from the side top anchor personnel platform 11, and operates the nine-way valve control panel 16 in the middle of the lifting platform 131 to make the side top anchor folding control panel 12 rotate to a vertical state. The workers install the railing on the lifting platform 131 to the outside of the side anchoring platform 11. At this time, the top anchoring workers are ready to board the machine and can carry out the top anchoring support operation. The workers then control the six-way valve control panel 18 to make the temporary support mechanism 17 support the top in the appropriate position. The auxiliary anchoring workers walk to the front of the oil tank section 50 and operate the control valve group to unfold the auxiliary anchoring tilting platform 216 and extend the auxiliary anchoring sliding mechanism 19. At this time, the workers board the machine from the auxiliary anchoring tilting platform 216 and operate the auxiliary anchoring drill 201 to complete the anchoring support operation under the control of the electrical system 80 and the hydraulic system 110.

[0084] When the drilling rig finishes its work and needs to pass other tunneling equipment in the roadway, the workers operate the six-valve control panel 18 and the nine-valve control panel 16 to retract the temporary support mechanism 17, so that the side top anchor control panel 12 rotates to a horizontal position. The workers install the railing on the side top anchor personnel platform 11 to the middle position of the lifting platform 131. The workers get off the machine through the ladder inside the side top anchor personnel platform 11. After the workers put away the ladder, the top anchor workers walk to the front of the oil tank section 50 and operate the control valve group to rotate the side top anchor personnel platforms 11 on both sides inward to a vertical position. At this time, the side top anchor drilling rig 101 rotates synchronously to a vertical position. The side anchor workers get off the side anchor tilting platform 216 and fold the side anchor tilting platform 216 through the control valve group in front of the oil tank section 50. The side anchor sliding mechanism 19 retracts. At this time, the drilling rig retraction is completed and the equipment can pass each other.

[0085] This invention features a compact five-arm anchor bolt and cable drilling rig with a rational overall structure, high-strength and rigid components, a compact design, full hydraulic control, and a high degree of mechanization. It employs a crawler-type locomotive and a reliable hydraulic-mechanical transmission system, resulting in a small turning radius and flexible maneuverability. The layout of three top anchor bolt drilling rigs and two side anchor bolt drilling rigs allows for simultaneous top and side support, improving support efficiency. It utilizes a large-area work platform and a folding tilting platform, ensuring good safety, reducing the labor intensity of workers, improving the working environment, and adapting to harsh conditions. It is an ideal safety support device for underground coal mining. It can achieve the goals of safe, efficient, and mechanized operations in my country's coal mining industry. Compared to similar wide-body anchor bolt drilling rigs that are only suitable for continuous mining and dual-roadway excavation processes, this equipment is applicable to a wider range of construction techniques.
