Description

Technical Field

[0001] This invention relates to the technical field of anchor bolt support, and more particularly to a telescopic and compact anchor bolt drilling rig. Background Technology

[0002] Bolt support is a fast, safe, and economical method of roadway and tunnel support. It represents the most advanced roadway and tunnel support technology and is the future direction of support technology for coal mine roadways and surface tunnels. Bolt support is an economical and effective support technology for coal roadways.

[0003] However, the level of automation in support operations for underground roadways and surface tunnels is still relatively low at present. Most roadway and tunnel support is carried out using machine-mounted ordinary anchor drilling rigs or manual handheld single drilling rigs. This has many hidden dangers and risks, such as long support time, a large number of workers, high labor intensity, low support efficiency, serious occupational disease hazards, and the need for operators to be in the unsupported area during working hours. As a result, mining and excavation are severely unbalanced, support time is long, and the progress of tunneling and coal mining efficiency are seriously affected. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a retractable and compact anchoring drill capable of fully automated support for roadways.

[0005] This invention provides a retractable and compact anchoring drilling rig, characterized in that it includes a frame, on which a drilling mechanism, an anchoring mechanism and a two-stage feed mechanism are provided;

The rising connecting plate is sleeved on the third guide posts and connected to the driving assembly. The drill box or the anchor box is connected to the rising connecting plate. Driving the driving assembly causes the rising connecting plate to move along the third guide posts, thereby causing the drill box or the anchor box to move along the third guide posts to advance the drill rod or the anchor rod.

[0009] Optionally, the drive assembly includes a fourth drive member, guide wheels, and a chain. The fourth drive member is disposed between the frame and the third guide column. The guide wheels are disposed on both sides of the top of the fourth drive member. The chain is arranged around the guide wheels. A swing mechanism is provided on the frame. One end of the chain is connected to the swing mechanism, and the other end is connected to the rising connecting plate.

[0010] Optionally, the rising connecting plate is provided with an electromagnet locking mechanism, which is used to position the drill box or the anchor box when the rising connecting plate moves.

[0011] Optionally, it also includes a switching mechanism, which includes multiple switching guide plates, a fixed base, a slide, two connecting plates, a third driving component, and a double switching block;

[0012] The fixed base is disposed at the bottom of the frame, the third driving member is disposed on the fixed base, the sliding groove is disposed on the frame, and the bottom of the third driving member is provided with a protrusion, the protrusion being adapted to slide along the sliding groove;

[0013] The two connecting plates are respectively disposed on opposite sides of the drill box and the anchor box. The double switching block is disposed on the third driving member, and its two sides are respectively connected to the two connecting plates. The top of the multiple switching guide plates is provided with a track. The two connecting plates are provided with guide members adapted to the track. The third driving member is driven to drive the drill box and the anchor box to move synchronously and switch.

[0014] Optionally, it also includes a support column mechanism, which includes a support column frame and a second guide column. The second guide column is disposed on one side of the support column frame. A first guide column and a guide rail are disposed on one side of the frame opposite to the second guide column, and a first driving member is disposed on both sides of the frame to drive the first driving member to move the support column mechanism along the guide rail.

[0015] Optionally, the support column mechanism further includes a top cone, a clamping link, and a fifth driving member. The top cone is disposed at the top of the support column, and the clamping link is disposed on one side of the support column. The fifth driving member is driven to open and close the clamping link so that the drill rod or anchor rod can pass through.

[0016] The lower end of the clamping link is inverted conical.

[0017] Optionally, it also includes a centering rod mechanism, which includes two sets of centering components. The two sets of centering components are respectively disposed on both sides of the frame, and the two sets of centering components are respectively used to fix the drill rod and the anchor rod.

[0018] Both sets of centering components include a ferrule, an outer sleeve, an inner sleeve, and a sixth drive member. The outer sleeve is disposed on the ferrule, and the inner sleeve is disposed inside the outer sleeve. Both the outer sleeve and the inner sleeve are hinged to the sixth drive member. The sixth drive member drives the inner sleeve to move along the axial direction of the outer sleeve. A central block is disposed on one side of the inner sleeve, and a positioning fork is disposed on the central block. Clamping wheels are respectively disposed on the two branches of the positioning fork, and the two clamping wheels limit the drill rod or the anchor rod.

The roller is mounted on the second fixed base. One end of the wire rope is wound around the roller, and the other end passes through and slides within the nozzle assembly. The seventh driving member is connected to the roller, and the eighth driving member is connected to the nozzle assembly. An anchoring agent is placed in the nozzle assembly. Driving the eighth driving member causes the nozzle assembly to move vertically to insert into a pre-drilled hole. Driving the seventh driving member causes the roller to rotate, thereby causing the wire rope to move along the inside of the nozzle assembly to deliver the anchoring agent into the borehole.

[0020] Optionally, the nozzle assembly includes a steel pipe, a flip cover, a handle, and a pipe clamp. The steel pipe has a receiving space for accommodating the anchoring agent. An opening is formed on the surface of the steel pipe. One end of the flip cover is hinged to the opening and covers the opening. The handle is disposed on the flip cover, and the pipe clamp is sleeved on the flip cover and the steel pipe.

[0021] The technical solution provided by the embodiments of the present invention has the following beneficial effects compared with the prior art:

[0022] This embodiment provides a telescopic and compact anchoring drill. By setting a two-stage feed mechanism on the frame, the second drive component is driven to extend, causing the entire frame to move upward in the vertical direction. At the same time, the drill box or anchor box also rises. At this time, the first slide moves along the surface of the first guide column, providing guidance for the frame movement and improving the stability of the frame movement, thus realizing the first stage of the anchoring drill. The drive component is then driven, causing the rising connecting plate to move upward along the third guide column, thereby driving the drill box and drill rod to rise until the drill rod reaches the set hole depth and stops moving. At this time, the drilling is completed, or the anchor box and anchor rod are driven to rise, thus realizing the second stage of the anchoring drill. This further compresses the height of the drill frame, allowing the anchoring drill to adapt to low tunnels and improving the applicability of small intelligent drills. At the same time, this anchoring drill realizes automatic drilling, improving work efficiency.

[0023] This retractable and compact anchor drilling rig improves construction safety and significantly reduces the incidence of occupational diseases. Traditional support equipment operators are prone to danger due to being in open roof areas. Hundreds of roof collapse accidents occur annually in anchor-supported roadways, and approximately 400,000 people in the anchoring industry suffer from pulmonary selenium. After using the retractable and compact anchor drilling rig, no manual operation is required, and operators can be kept away from the construction area, ensuring the safety and health of the operators. At the same time, the retractable and compact anchor drilling rig reduces the number of operators and increases production efficiency. A traditional single anchor drilling rig requires 3 to 4 people to work together, while the retractable and compact anchor drilling rig only requires 1 to 2 people, reducing the number of people on the work face and reducing labor costs.

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the invention, and not all embodiments.

[0039] Reference Figures 1 to 10 As shown, this embodiment provides a telescopic and compact anchoring drill, including a frame 1, on which a drilling mechanism 2, an anchoring mechanism 3 and a secondary feed mechanism 4 are provided.

[0040] Among them, reference Figure 1 , Figure 2 and Figure 3 As shown, the frame 1 includes a frame 101, on which a first guide post 102 is provided. The drilling mechanism 2 and the anchoring mechanism 3 are both provided on the frame 101. The drilling mechanism 2 includes a drill box 201 and a drill rod provided on the drill box 201. The anchoring mechanism 3 includes an anchor box 301 and an anchor rod provided on the anchor box 301. The drill box 201 and the anchor box 301 are both slidably provided on the secondary feed mechanism 4. The frame 1 is made of metal, preferably a high-strength alloy steel structure, but it can also be a carbon fiber structure.

[0041] Reference Figure 4 and Figure 5As shown, the secondary feed mechanism 4 includes a frame 401, a rising connecting plate 402, a second driving member 403, and a driving assembly. One end of the second driving member 403 is connected to the frame 101, and the other end is connected to the frame 401. The secondary feed mechanism 4 has a first sliding groove 404 on one side opposite to the first guide post 102. Driving the second driving member 403 causes the frame 401 to move along the extension direction of the first guide post 102. The frame 401 has two third guide posts 405 inside. The rising connecting plate 402 is sleeved on the third guide posts 405 and connected to the driving assembly. The drill box 201 or the anchor box 301 is connected to the rising connecting plate 402. Driving the driving assembly causes the rising connecting plate 402 to move along the third guide post 405, thereby causing the drill box 201 or the anchor box 301 to move along the third guide post 405 to advance the drill rod or anchor rod feed. Specifically, the second driving component 403 connects the frame 401 and the frame 101. The frame 401 has a connecting lug 411 on one side where the first sliding groove 404 is located. One end of the second driving component 403 is connected to the connecting lug 411, driving the second driving component 403 to extend, causing the frame 401 to move vertically upwards. Simultaneously, the drill box 201 or anchor box 301 also rises. At this time, the first sliding groove 404 moves along the surface of the first guide post 102, providing guidance for the movement of the frame 401 and improving the stability of the frame 401's movement. This achieves the first stage of the anchor drilling rig's ascent, driving the drive assembly to move the rising connecting plate 402 upwards along the third guide post 405, thereby driving the drill box 201 and drill rod upwards until the drill rod reaches the set hole depth and stops moving. At this point, drilling is complete. This can either raise the anchor box 301 and the anchor rod, achieving a two-stage rise for the anchor protection drilling rig, or drive the drive assembly to make the rising connecting plate 402 move downward along the third guide column 405, thereby lowering the drill box 201 and the drill rod, or lowering the anchor box 301 and the anchor rod. When the drive assembly descends to its limit, it drives the second drive component 403 to retract, causing the frame 401 to move downward vertically as a whole, while the drill box 201 also descends until it falls to the bottom of the frame 101, completing the automatic drilling, or the anchor box 301 falls to the bottom of the frame 101. This anchor protection drilling rig can perform two-stage rises, thereby further compressing the height of the drilling frame, making the anchor protection drilling rig adaptable to low tunnels, improving the applicability of small intelligent drilling rigs, and achieving automatic drilling, thus improving work efficiency.

[0042] This retractable and compact anchor drilling rig improves construction safety and significantly reduces the incidence of occupational diseases. Traditional support equipment operators are prone to danger due to being in open roof areas. Hundreds of roof collapse accidents occur annually in anchor-supported roadways, and approximately 400,000 people in the anchoring industry suffer from pulmonary selenium. After using the retractable and compact anchor drilling rig, no manual operation is required, and operators can be kept away from the construction area, ensuring the safety and health of the operators. At the same time, the retractable and compact anchor drilling rig reduces the number of operators and increases production efficiency. A traditional single anchor drilling rig requires 3 to 4 people to work together, while the retractable and compact anchor drilling rig only requires 1 to 2 people, reducing the number of people on the work face and reducing labor costs.

[0043] Further, continue to refer to Figure 4 As shown, the drive assembly includes a fourth drive member 406, a guide wheel 407, and a chain 408. The fourth drive member 406 is disposed between the frame 401 and the third guide column 405. The guide wheel 407 is disposed on both sides of the top of the fourth drive member 406. The chain 408 is arranged around the guide wheel 407. A swing mechanism 409 is provided on the frame 401. One end of the chain 408 is connected to the swing mechanism 409, and the other end is connected to the rising connecting plate 402. Specifically, the fourth driving component 406 is a lifting driving cylinder. Guide wheels 407 are located on both sides of the top of the cylinder barrel of the lifting driving cylinder. The chain 408 includes two chains, which are respectively arranged around the two guide wheels 407. One end of the chain 408 is fixed to the swing mechanism 409, so that the force on the chain 408 is reduced during the drilling process and the service life of the chain 408 is extended. The other end is connected to the lifting connecting plate 402, so that when the cylinder barrel of the lifting driving cylinder moves, it can drive the chain 408 to rotate, thereby driving the lifting connecting plate 402 to move along the third guide post 405, thereby driving the drill box 201 or the anchor box 301 to move.

[0044] Reference Figure 6 As shown, an electromagnet locking component 410 is provided on the rising connecting plate 402. The electromagnet locking component 410 is used to position the drill box 201 or the anchor box 301 when the rising connecting plate 402 moves.

[0045] In some embodiments, refer to Figure 3As shown, it also includes a switching mechanism 5, which includes multiple switching guide plates 501, a first fixed seat 502, a second slide groove 503, two connecting plates 504, a third driving member 505, and a double switching block 506. The first fixed seat 502 is located at the bottom of the frame 101, the third driving member 505 is located on the first fixed seat 502, the second slide groove 503 is located on the frame 101, and the bottom of the third driving member 505 is provided with a protrusion, which is adapted to slide along the second slide groove 503. The two connecting plates 504 are respectively located on opposite sides of the drill box 201 and the anchor box 301. The double switching block 506 is located on the third driving member 505, and its two sides are respectively connected to the two connecting plates 504. The top of each of the multiple switching guide plates 501 is provided with a track 507, and the two connecting plates 504 are provided with guide members adapted to the track 507. The third driving member 505 drives the drill box 201 and the anchor box 301 to move synchronously and switch. Specifically, multiple switching guide plates 501 are arranged side by side, with one side connected to the rising connecting plate 402 and the other side slidably connected to the drill box 201 and the anchor box 301. The third driving component 505 drives the drill box 201 and the anchor box 301 to slide along the switching guide plates 501. Each side of the drill box 201 and the anchor box 301 is connected to a connecting plate 504, and both connecting plates 504 have grooves. The double-connecting block 506 has protrusions on both sides facing the two connecting plates 504 that fit the grooves, allowing the double-connecting block 506 to connect with the two connecting plates 504. This connects the third driving component 505 to the drill box 201 and the anchor box 301, enabling the third driving component 505 to slide. 05 can drive the drill box 201 and anchor box 301 to move synchronously and switch. At the same time, the bottom of the third drive component 505 is provided with a protrusion that is adapted to the second slide groove 503, which not only guides the movement of the third drive component 505, but also improves the stability of the movement of the third drive component 505. Meanwhile, the top of the multiple switching guide plates 501 is provided with a track 507, and the two connecting plates 504 are provided with guides adapted to the track 507. The guides and the track 507 are arranged horizontally. When the frame 201 is lowered to the lowest position, the third drive component 505 can drive the guides on the drill-anchor box connecting plate 504 to slide on the track 507, which facilitates the simultaneous movement of the drill box 201 and anchor box 301.

[0046] In other embodiments, reference is made to Figure 5 and Figure 7As shown, it also includes a support column mechanism 6, which includes a support column frame 601 and a second guide column 602. The second guide column 602 is disposed on one side of the support column frame 601. A guide rail 103 is disposed on the side of the frame 101 opposite to the second guide column 602, and a first driving member 104 is disposed on both sides of the guide rail 103. The first driving member 104 drives the support column mechanism 6 to move along the guide rail 103. The support column mechanism 6 also includes a top cone 603, a clamping link 604 and a fifth driving member 605. The top cone 603 is disposed on the top of the support column frame 601, and the clamping link 604 is disposed on one side of the support column frame 601. The fifth driving member 605 drives the clamping link 604 to open and close so that the drill rod or anchor rod can pass through. The lower end of the clamping link 604 is inverted conical. Specifically, the top-connecting cone 603 can reliably contact the coal wall, and the fifth driving component 605 is a clamping cylinder. The clamping cylinder can drive the clamping connecting rod 604 to open and close. The lower end of the clamping connecting rod 604 is inverted conical, which can guide the drill rod and anchor rod when they pass through the clamping jaws. Driving the first driving component 104 can drive the support column mechanism 6 to move along the guide rail 103, thereby realizing the top-connecting of the anchoring drilling rig.

[0047] Reference Figure 8 As shown, in order to position the drill rod at the theoretical drilling position, a centering rod protection mechanism 7 is also included. The centering rod protection mechanism 7 includes two sets of centering components, which are respectively arranged on both sides of the frame 101. The two sets of centering components are used to fix the drill rod and the anchor rod respectively. Each set of centering components includes a sling arm 701, an outer sleeve 702, an inner sleeve 703, and a sixth driving member 704. The outer sleeve 702 is arranged on the sling arm 701, and the inner sleeve 703 is arranged inside the outer sleeve 702. Both the outer sleeve 702 and the inner sleeve 703 are connected to the sixth driving member 704. The sixth driving member 704 drives the inner sleeve 703 to move along the axial direction of the outer sleeve 702. A central block 705 is arranged on one side of the inner sleeve 703. A positioning fork 706 is arranged on the central block 705. A clamping wheel 707 is arranged on the two branches of the positioning fork 706. The two clamping wheels 707 limit the drill rod or the anchor rod. Specifically, a sliding arm is provided on the frame 101, and a closing arm 701 is provided on the sliding arm, so that the centering assembly is set on the frame 101 as a whole. Two sets of clamping wheels 707 are used to clamp the drill rod and the anchor rod respectively, so that the drill rod can be centered and limited during drilling. Specifically, the outer sleeve 702 and the inner sleeve 703 are restricted to circumferential rotation by an axially provided guide key. The outer sleeve 702 is provided on the sliding arm, and the inner sleeve 703 is connected to the closing arm 701. The sixth driving member 704 drives the inner sleeve 703 to extend and retract along the axial direction of the outer sleeve 702, thereby driving the central block 705, the positioning fork 706 and the clamping wheel 707 to move synchronously to center and limit the drill rod and the anchor rod. At this time, the switching mechanism 5 is driven so that the drill rod and the anchor rod can be switched synchronously.

[0048] Reference Figure 8 and Figure 9 As shown, it also includes a drug delivery mechanism 8, which includes a second fixed base 801, a seventh driving member 802, a roller 803, a steel wire rope 804, a nozzle assembly 809, and an eighth driving member 810. The roller 803 is mounted on the second fixed base 801. One end of the steel wire rope 804 is wrapped around the roller 803, and the other end passes through and slides in the nozzle assembly 809. The seventh driving member 802 is connected to the roller 803, and the eighth driving member 810 is connected to the nozzle assembly 809. An anchoring agent is placed in the nozzle assembly 809. Driving the eighth driving member 810 drives the nozzle assembly 809 to move vertically. The directional movement inserts into the pre-drilled hole, driving the seventh drive component 802 to rotate the roller 803, thereby driving the wire rope 804 to move along the inside of the nozzle assembly 809 to deliver the anchoring agent into the hole. The nozzle assembly 809 includes a steel pipe 805, a flip cover 806, a handle 807, and a pipe clamp 808. The steel pipe 805 has a receiving space for accommodating the anchoring agent, and an opening is provided on the surface of the steel pipe 805. One end of the flip cover 806 is hinged to the opening and covers the opening. The handle 807 is disposed on the flip cover 806, and the pipe clamp 808 is sleeved on the flip cover 806 and the steel pipe 805. Specifically, the eighth drive 810 drives the nozzle assembly 809 to move upward and insert it into the pre-drilled hole. Subsequently, the seventh drive 802 drives the roller 803 to rotate, thereby causing the wire rope 804 to move upward along the inside of the steel pipe 805. At this time, the top of the wire rope 804 contacts the anchoring agent. The upward movement of the wire rope 804 causes the anchoring agent to move upward as well, so that the anchoring agent in the nozzle assembly 809 is delivered into the pre-drilled hole. When loading the anchoring agent into the nozzle assembly 809, the operator can pull up the handle 807 to open the flip cover 806, load the anchoring agent into the steel pipe 805 through the opening, close the flip cover 806, and put the pipe clamp 808 on the flip cover 806 to fix the flip cover 806 to the steel pipe 805 and prevent the anchoring agent from leaking when the flip cover 806 is opened.

[0049] Of course, the integrated anchor bolt 9 can also be used for delivery of the explosive, as described in the following reference. Figure 10 As shown, the integrated anchor bolt 9 includes a sealing ring 901, a expansion plug 902, a fastening nut 903, a tray 904, a hollow rod body 905, and an anchoring agent 906. The anchoring agent 906 is installed in the middle of the hollow rod body 905, and the expansion plugs 902 are installed at both ends. The sealing ring 901 is installed on the lower end face of the hollow rod body 905, which can maintain the seal between the rod body and the anchor box 301 and ensure a certain water pressure.

[0050] This anchoring drilling rig also includes an electrical system, comprising a host computer, sensor array, and controller array. The controller array connects to a wireless remote controller via a receiver to automate the entire anchor support process. Customized settings for anchor drilling procedures under different geological conditions allow operators to visually set drilling parameters, improving work efficiency. Furthermore, it can execute operator commands and provide real-time dynamic feedback on system status, offering data recording, querying, analysis, diagnostics, and early warning functions.

[0051] The hydraulic system uses a CAN bus and solenoid valve group to control each driving component.

[0052] The working process of the above-mentioned retractable and compact anchoring drilling rig is as follows.

[0053] When using ordinary anchor bolts, the first step is to operate the first drive component 104 to drive the support column mechanism 6 to connect to the top, ensuring that the top connection cone 603 is firmly positioned. All states are in the initial position. The centering rod mechanism 7 positions the drill rod at the theoretical drilling position. The anchor box 301 is equipped with anchor bolts, and the nozzle assembly 809 is filled with anchoring agent.

[0054] In the second step, the electrical system starts the automatic drilling program. After the drill box 201 rotates the drill rod, the second drive member 403 extends, driving the entire secondary feed mechanism 4 to rise. The drill box 201 also rises accordingly. When it reaches the limit position, the centering rod mechanism 7, pushed by the sixth drive member 704, causes the drill rod to leave the clamping wheel 707. The cylinder of the fourth drive member 406 begins to move, driving the rising connecting plate 402 to rise along the third guide post 405, which in turn drives the drill box 201 and the drill rod to rise. When the set hole depth is reached, the rise stops. Then, the fourth drive member 406 drives the drill box 6 and the drill rod to descend. After the fourth drive member 406 descends to the limit, the centering rod mechanism 7, pushed by the sixth drive member 704, pushes the drill rod into the clamping wheel 707. Then, the second drive member 403 retracts, driving the entire secondary feed mechanism 4 to descend. The drill box 201 also descends accordingly until it reaches the lowest position, and the automatic drilling program is completed.

[0055] Third, the electrical system starts the automatic drug delivery program. The seventh drive component 802 of the drug delivery mechanism 8 can drive the roller 803 to rotate. Under the action of the roller 803, the wire rope 804 can slide upward along the inside of the nozzle assembly 809, thereby delivering the anchoring agent into the drilled hole.

[0056] In the fourth step, the electrical system starts the automatic switching program, the electromagnet locking component 410 is unlocked, and the drill rod and anchor rod are switched synchronously under the synchronous action of the centering rod mechanism 7, the sixth driving component 704 and the third driving component 505 of the lower switching mechanism 5. The anchor box 301 and the anchor rod enter the working position from the waiting position, the electromagnet locking component 410 is locked, and the automatic switching program is completed.

[0057] Fifth, the electrical system initiates the automatic anchor bolt delivery and fastening procedure. The second drive component 403 extends, driving the entire secondary feed mechanism 4 to rise. The anchor box 301 and the anchor bolt also rise accordingly. After reaching the top, the centering guard rod mechanism 7, pushed by the sixth drive component 704, moves away from the anchor bolt. When the cylinder of the fourth drive component 406 moves, it drives the rising connecting plate 402 to rise along the third guide column 405, thereby driving the anchor box 301 and the anchor bolt to rise. The fourth drive component 406 stops rising when the pressure sensor detects that the tray 905 is in contact with the top. 301 begins to rotate, squeezing out the anchoring agent. Then, the anchor box 301 drives the anchor rod to rotate at high speed, completely stirring the coagulant in the agent roll. After the coagulant completely bonds the anchor rod to the borehole, the fastening nut 903 is tightened. Then, the sixth drive component 704 drives the anchor box 301 to descend. After the sixth drive component 704 descends to its limit, the second drive component 403 retracts, driving the entire secondary feed mechanism 4 to descend. The anchor box 301 also descends along with it until it reaches the lowest position. The switching mechanism 5 returns to the initial position, and the automatic anchor rod feeding and tightening program is completed.

[0058] The electrical system initiates an automatic reset procedure, restoring all positions to their initial positions and awaiting the next work cycle.

[0059] When using the integrated anchor bolt 9, the third step in the above workflow is removed, and the fifth step is replaced by the extension of the second drive component 403, which drives the entire secondary feed mechanism 4 to rise. The anchor box 301 and the integrated anchor bolt 9 also rise accordingly. After rising to the top, the centering guard rod mechanism 7 is pushed away from the anchor bolt by the sixth drive component 704. When the cylinder of the fourth drive component 406 moves, it can drive the rising connecting plate 402 to rise along the third guide column 405, thereby driving the anchor box 301 and the anchor bolt to rise. When the fourth drive component 406 senses that the tray 905 is in contact with the top through the pressure sensor, the rise stops, and the anchor box 301 opens the high-pressure water. A closed water seal is formed between the high-pressure water sealing ring 901 and the anchor box 301. Sufficient pressure is maintained in the middle of the path, and the expansion plug 902 is pushed forward. Under the impetus of high-pressure water, the anchoring agent 906 is delivered into the hole and squeezed out between the drill hole and the anchor rod. Then, the anchor box 301 drives the integrated anchor rod 9 to rotate at high speed to completely stir the coagulant in the agent roll. After the coagulant completely bonds the anchor rod to the drill hole, the fastening nut 903 is tightened. Then, the fourth drive component 406 drives the anchor box 301 to descend. After the fourth drive component 406 descends to its limit, the second drive component 403 retracts, driving the entire secondary feed mechanism 4 to descend. The anchor box 301 also descends with it until it reaches the lowest position. The switching mechanism 5 returns to the initial position, and the automatic delivery of the anchoring agent 906, the anchor rod, and the tightening process are completed.

[0060] The electrical system initiates an automatic reset procedure, restoring all positions to their initial positions and awaiting the next work cycle.

[0061] Traditional support equipment mainly relies on manual carrying, lifting, and hoisting, which is labor-intensive. After using the above-mentioned retractable and compact anchor drilling rig, the entire process of anchoring is automated, eliminating the need for manual delivery of materials, installation of anchor bolts, and tightening, thus greatly reducing the labor intensity of workers.
