Description

Technical Field

[0001] This invention relates to the field of top anchor cable support technology, and in particular to a double-arm automatic anchor cable drilling rig for roadway anchor cable support. Background Technology

[0002] Currently, in roadway anchor cable support operations, due to the depth of the anchor cable holes, frequent connection and disconnection of drill rods is required during drilling. However, most existing anchor cable drilling rigs require manual connection and replacement of drill rods, a cumbersome process. Furthermore, during drill rod replacement, issues such as borehole deviation and inaccurate straightness of multiple drill rod connections can lead to borehole collapse, ultimately resulting in low anchor cable support efficiency. Existing drilling rigs also suffer from a small working platform area, hindering operators from performing tasks such as threading anchor cables, mixing, and tensioning after automatic drilling. When the working platform is raised, it is difficult for workers to safely disembark, affecting the safety of the working environment. Additionally, the inconvenient operation can easily lead to borehole deviation, affecting drill rod connections and consequently impacting support strength. Summary of the Invention

[0022] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown, one embodiment of the present invention provides a dual-arm automatic anchor cable drilling rig for roadway anchor cable support. The dual-arm automatic anchor cable drilling rig 100 includes: The walking unit 101 has a front body 122 and a rear body 116 detachably connected to it. The working platform 117 is located above the walking unit 101. The end of the working platform 117 away from the rear body 116 is hinged to the front connecting beam 124. The end of the front connecting beam 124 away from the working platform 117 is hinged to the end of the front body 122 facing the rear body 116. The end of the working platform 117 facing the rear body 116 is hinged to the central passage ladder. The end of the central passage ladder 123 away from the working platform 117 is hinged to the rear body 116. The front body 122, the rear body 116, the front connecting beam 124, the central passage ladder 123 and the working platform 117 form a four-bar linkage mechanism. The platform lifting cylinder 121 is hinged at one end to the end of the front body 122 away from the rear body 116, and the other end of the platform lifting cylinder 121 is hinged to the end of the working platform 117 facing the rear body 116.

[0024] The dual-arm automatic anchor cable drilling rig 100 includes a traveling section 101, a front body 122 and a rear body 116 located on both sides of the traveling section 101 along its length, and a working platform 117 located above the traveling section 101. The end of the working platform 117 away from the rear body 116 is hinged to a front connecting beam 124, and the end of the working platform 117 facing the rear body 116 is hinged to a central access ladder 123. The end of the front connecting beam 124 away from the working platform 117 is hinged to the end of the front body 122 facing the rear body 116, and the end of the central access ladder 123 away from the working platform 117 is hinged to the rear body 116. The front body 122, rear body 116, front connecting beam 124, central access ladder 123, and working platform 117 form a four-bar linkage. One end of the platform lifting cylinder 121 is hinged to the end of the front body 122 away from the rear body 116. The other end of cylinder 121 is hinged to the end of the work platform 117 facing the rear body 116. When the platform lifting cylinder 121 extends, the work platform 117 and the central passage ladder 123 are raised away from the traveling part 101, realizing the raising of the work platform 117 and the connection of the central passage ladder 123, making it convenient for workers to enter the work platform 117 through the central passage ladder 123. When the platform lifting cylinder 121 retracts, under the power of the hinge point and the platform lifting cylinder 121, the work platform 117 and the central passage ladder 123 move towards the traveling part 101, realizing the lowering of the work platform 117. At this time, workers can also enter the work platform 117 through the central passage ladder 123, improving the convenience for workers to reach the work platform 117, improving the safety of workers getting on and off the vehicle, and providing a good working environment for workers.

[0025] It should be noted that the walking unit 101 is a hydraulically driven tracked walking mechanism that can adapt to the working environment of the tunnel. The track has internal support components. The front body 122 and the rear body 116 are fixedly connected to the support components, which can usually be bolted and / or keyed, forming the chassis of this double-arm automatic anchor cable drilling rig 100, which becomes the fixed base for other components.

[0026] For example, a pin seat can be provided on the front body 122, and a hinge shaft can be inserted into the pin seat. It can be connected with the hinge shaft on the front connecting beam 124, the central passage ladder 123 and the working platform 117 to form a four-bar linkage mechanism. This four-bar linkage mechanism is then hinged to the platform lifting cylinder 121. The lifting and lowering of the working platform 117 is realized through the extension and retraction of the platform lifting cylinder 121, thereby improving the stability and reliability of the lifting and lowering of the working platform 117.

[0027] For example, the central access ladder 123 is hinged at both ends to the work platform 117 and the rear body 116 via pins, allowing the central access ladder 123 to adjust its angle as the work platform 117 rises and falls. The central access ladder 123 is located between a pair of front connecting beams 124, and a pair of platform lifting cylinders 121 are located outside the pair of front connecting beams 124, further improving the reliability and stability of supporting the lifting of the work platform 117. The central access ladder 123 is typically about 1 meter wide, with each ladder surface forming a small four-bar linkage structure via an internal connecting rod, a support plate on the side of the ladder surface, the ladder surface, and the hinge shaft between the internal connecting rod and the support plate. When the support plate swings with the front connecting beams 124, the internal connecting rod swings along with it, ensuring that the ladder surfaces hinged to both remain horizontal. This ensures that each ladder surface remains horizontal during the lifting of the work platform 117. Figure 5 As shown, this allows workers on the vehicle to smoothly and quickly board and disembark from the work platform 117, regardless of its height, and to stand on any step. This is the same principle behind how the work platform 117 maintains a horizontal position through a four-bar linkage.

[0028] In one feasible implementation, such as Figure 1 and Figure 2 As shown, the dual-arm automatic anchor cable drilling rig 100 also includes: Workbench flaps 110 are located at both ends of the work platform 117 and are hinged to the work platform 117. The flip-plate retraction cylinder 109 is hinged at one end to the work platform 117, and the other end of the flip-plate retraction cylinder 109 is hinged to the end of the worktable flip plate 110 away from the work platform 117. The hinge point between the flip-plate retraction cylinder 109 and the work platform 117 is lower than the hinge point between the flip-plate retraction cylinder 109 and the worktable flip plate 110.

[0029] in, Figure 1 The left and right sides of the working platform 117 are connected to the flap retraction cylinder 109 via hinge shafts. The other end of the flap retraction cylinder 109 is hinged to the worktable flap 110. The flap retraction cylinder 109 extends and retracts, allowing the worktable flap 110 to be retracted or extended to adapt to different space requirements. For example, when the flap retraction cylinder 109 extends, the worktable flap 110 is approximately 180° to the working platform 117, further expanding the operating space. When the roadway is too narrow, the flap retraction cylinder 109 can be retracted, causing the worktable flap 110 to rotate around the working platform 117, gradually turning towards the working platform 117. This reduces the width of the double-arm automatic anchor cable drilling rig 100, facilitating passage through narrow areas or working in narrow areas, thus increasing the applicability of the double-arm automatic anchor cable drilling rig 100.

[0030] In one feasible implementation, such as Figure 1 As shown, the dual-arm automatic anchor cable drilling rig 100 also includes: The sliding box 102 is fixedly installed at the end of the working platform 117 away from the rear body 116; The sliding box telescopic arms 103 are provided at both ends of the sliding box section 103, and the sliding box telescopic arms 103 are configured to extend and retract within the sliding box section 102. A pair of sliding box telescopic arms 103 extend toward the side of the walking section 101 away from the front body 122. The first drill arm 107 and the second drill arm 118 are respectively disposed at the ends of a pair of sliding box telescopic arms 103 away from the sliding box section 102 via connecting components.

[0031] The front end of the working platform 117 is fixedly connected to the sliding box section 102 via positioning pins, stops, and bolts, allowing the sliding box section 102 to rise and fall together with the working platform 117, that is, enabling the first drill arm 107 and the second drill arm 118 to rise and fall simultaneously. A secondary telescopic square tube, namely the sliding box telescopic arm 103, is provided on both sides of the sliding box section 102. This telescopic arm 103 achieves a large stroke extension and retraction from a spacing of 1.9 meters to 5.0 meters via the extension and retraction of an internal telescopic cylinder, meeting the requirement of drilling a row of top anchor cable holes in the tunnel roof along the width of the dual-arm automatic anchor cable drilling rig 100 in a single stop, thus improving the efficiency of drilling anchor cable holes. It is understood that the fixing connection of positioning pins, stops, and bolts is a common technique in this field and will not be elaborated further.

[0032] For example, a sliding box section 102 can be provided, divided into two spaces by a partition. A sliding box telescopic arm 103 is installed in each of the two spaces, allowing both sliding box telescopic arms 103 to work simultaneously. This arrangement ensures that the first drill arm 107 and the second drill arm 118 have the same height. Alternatively, two sliding box sections 102 can be stacked along the height of the dual-arm automatic anchor cable drilling rig 100, with the opening of one sliding box section 102 facing... Figure 1 On the left side, an opening of a sliding section 102 faces... Figure 1 On the right side, a sliding box telescopic arm 103 is respectively set in the two sliding box sections 102. The extension and retraction of the pair of sliding box telescopic arms 103 respectively drive the first drill arm 107 and the second drill arm 115 in the width direction of the double-arm automatic anchor cable drilling rig 100. Figure 1 For the movement in the left and right directions, such a setup requires the lengths of the first drill arm 107 and the second drill arm 118 to be the same as the height difference between the two stacked sliding box sections 102.

[0033] In one feasible implementation, such as Figure 4 As shown, the connection components include: The sliding box drill arm connecting shaft 104 is located at the end of the sliding box telescopic arm 103 away from the sliding box part 102. The sliding box drill arm connecting shaft 104 is rotatably connected to the sliding box telescopic arm 103 and passes through the sliding box telescopic arm 103. The drill arm connecting seat 105 is fixedly connected to the end of the sliding box drill arm connecting shaft 104 facing the working platform 117; The drill arm front and rear adjustment cylinder 106 has one end hinged to the drill arm connecting seat 105 on the side away from the slide box drill arm connecting shaft 104, and the other end of the drill arm front and rear adjustment cylinder 106 is connected to the first drill arm 107. The second drill arm 118 is connected in the same way as the first drill arm 107.

[0034] It should be noted that the end of the sliding box telescopic arm 103 is provided with a rotatable sliding box drill arm connecting shaft 104. The end of the sliding box drill arm connecting shaft 104 opposite to the sliding box telescopic arm 103 is provided with a square stop and a connecting flange. The sliding box drill arm connecting shaft 104 and the drill arm connecting seat 105 are connected by the square stop, the connecting flange and bolts. The drill arm connecting seat 105 is connected to the drill arm front and rear adjustment cylinder 106 and the first drill arm 107 through a hinge shaft. The extension and retraction of the drill arm front and rear adjustment cylinder 106 can drive the first drill arm 107 to swing in the front and rear direction, that is, swing back and forth in the traveling direction of the double-arm automatic anchor cable drilling rig 100. Specifically, when the drill arm front-to-back adjustment cylinder 106 extends, the first drill arm 107 swings towards the rear body 116; when the drill arm front-to-back adjustment cylinder 106 retracts, the first drill arm 107 swings towards the front body 122; when the drill arm front-to-back adjustment cylinder 106 is in the middle extended position, the first drill arm 107 can be vertically upward. This setting can meet the angle adjustment of the double-arm automatic anchor cable drilling rig 100 in the front-to-back direction, and is suitable for drilling different anchor cable holes, thus improving the applicability of the double-arm automatic anchor cable drilling rig.

[0035] It should be noted that the connection method of the second drill arm 118 is the same as that of the first drill arm 107, and will not be repeated here.

[0036] In one feasible implementation, the connection component further includes: The articulated plate is fixedly installed at one end of the sliding box drill arm connecting shaft 104 away from the working platform 117; A pair of drill arm left and right adjustment cylinders 119 are located at the upper and lower ends of the hinge plate, respectively. One end of the drill arm left and right adjustment cylinder 119 is hinged to the hinge plate, and the other end of the drill arm left and right adjustment cylinder 119 is hinged to the end of the slide box telescopic arm 103 away from the slide box part 102.

[0037] Among them, the end of the sliding box drill arm connecting shaft 104 away from the drill arm connecting seat 105 is connected by a hinge plate. Figure 1 Two hydraulic cylinders 119, hinged vertically, adjust the left and right sides of the drill arms. By extending the upper and lower cylinders 119 to different lengths, the swing angles of the first drill arm 107 and the second drill arm 118 are controlled. For example, if the extension length of the upper cylinder 119 is greater than that of the lower cylinder 119, the first and second drill arms 107 and 118 swing away from the working platform 117. If the extension length of the lower cylinder 119 is greater than that of the upper cylinder 119, the first and second drill arms 107 and 118 swing closer to the working platform 117. If the extension length of the upper cylinder 119 is equal to that of the lower cylinder 119, the first and second drill arms 107 and 118 are vertically upward. This allows for angle adjustment of the anchor cable hole in the width direction of the dual-arm automatic anchor cable drilling rig 100, making it suitable for drilling different anchor cable holes and expanding the applicability of the dual-arm automatic anchor cable drilling rig.

[0038] In one feasible implementation, such as Figure 1 and Figure 2 As shown, the dual-arm automatic anchor cable drilling rig 100 also includes: An anchor cable conveyor 130 is disposed at the end of the first drill arm 107 and the second drill arm 118 away from the connecting assembly. The conveying center of the pair of anchor cable conveyors 130 is coaxially disposed with the drilling center of the first drill arm 107 and the second drill arm 118, respectively. The drill arm support cylinder 108 is located at the end of the first drill arm 107 and the second drill arm 118 away from the connecting assembly. The drill arm support cylinder 108 is located on the side of the anchor cable conveyor 130 away from the worktable 117.

[0039] An anchor cable conveyor 130 is fixedly installed at the end of the first drill arm 107 and the second drill arm 118 away from the walking part 101. The conveying center of the anchor cable conveyor 130 is coaxially set with the drilling center of the drill arm (first drill arm 107 and second drill arm 118). After the operator inserts the medicine roll into the drill arm automatic drilling machine, he can directly thread one end of the anchor cable into the hole, and then control the anchor cable conveyor 130 to clamp the anchor cable and convey it upward. Specifically, after the drilling arms (first drilling arm 107 and second drilling arm 118) complete the drilling operation, the operator only needs to accurately insert the anchoring cartridge into the borehole, and then hold one end of the anchor cable. With the help of the coaxial positioning structure between the drilling center of the drilling arm and the anchor cable conveyor 130, the end of the anchor cable can be easily threaded into the formed borehole. Then, the anchor cable conveyor 130 is controlled by the front operating panel 113 to perform the anchor cable clamping action, so that it can clamp the anchor cable smoothly and firmly. After the clamping action is completed, the anchor cable conveyor 130 is controlled by the front operating panel 113 to perform the anchor cable pushing action, so that the anchor cable advances at a constant speed along the center line of the hole under the action of coaxial force until the preset installation depth is reached. The anchor cable can be pushed in by lifting and lowering the drilling arm. This structural design allows the anchor cable conveyor 130 to be in different positions before and after drilling without affecting the movement of mechanical components within the process. Furthermore, during anchor cable delivery, it eliminates the need for secondary alignment after drilling; the anchor cable is directly fed into the hole via the anchor cable conveyor 130. This prevents anchor cable misalignment, improves the coaxiality of the anchor cable and the anchor cable hole, and enhances the safety and reliability of anchor cable installation. It is understood that the anchor cable conveyor can be purchased and installed directly at the designated location in this application, thus fulfilling the usage requirements of this application.

[0040] Furthermore, a drill arm support cylinder 108 is fixedly installed on the end of the first drill arm 107 and the second drill arm 118 away from the traveling part 101. Through the different extension and retraction strokes of the drill arm support cylinder 108, the first drill arm 107 and the second drill arm 118, which are raised and lowered synchronously, are supported at the same time and reach the uneven top surface of the roadway caused by over-excavation or under-excavation. The first drill arm 107 and the second drill arm 118 are respectively tightly connected to the top of the roadway. Relying on the telescopic nature of the drill arm support cylinder 108, the front end of the drill arm support cylinder 108 can stably contact the extreme position of the uneven top surface, making the contact between the front end of the drill arm support cylinder 108 and the uneven top surface formed by over-excavation or under-excavation of the roadway more secure and reliable. This adds a second fixed position and avoids the problem of insufficient contact between the front end plane of the first drill arm 107 and the second drill arm 118 and the uneven top surface formed by over-excavation or under-excavation of the roadway, which would cause the drill arm to be unstable or even suspended between itself and the roadway top. This ensures that the first drill arm 107 and the second drill arm 118 do not move relative to each other during drilling, thus improving the stability of the drilling.

[0041] In one feasible implementation, such as Figures 1 to 3As shown, the dual-arm automatic anchor cable drilling rig 100 also includes: The material hopper 111 is fixedly installed on the work platform 117, and the work area lighting lamp 112 is provided on the material hopper 111 via a universal joint; The front operating platform 113 is fixedly installed on the working platform 117. The front operating platform 113 is located on the side of the material hopper 111 away from the rear body 116.

[0042] The work platform 117 can be equipped with multiple material hoppers 111. In this embodiment, two material hoppers 111 form a group, and two groups of material hoppers 111 are set on the work platform 117. The two material hoppers 111 in each group have different dimensions, that is, different lengths and widths, and the depths can be the same or different. This allows for the classified storage of materials such as trays, drill rods, locks, and anchoring agents, making it convenient for workers to access them. The material hoppers 111 are fixedly connected to the work platform 117 by support columns and bolts. The height of the support columns is set according to the height that is convenient for workers to access, or the support columns can be set to a telescopic form, making it easy for workers to adjust the height of the material hoppers.

[0043] Furthermore, a working area lighting lamp 112 can be connected to the material hopper 111 via a universal joint. The working area lighting lamp 112 typically shines upwards, facilitating observation of the tunnel roof by workers and improving the accuracy of observation. This provides a stable working foundation for subsequent drilling and anchor cable installation. The universal joint can be used to adjust the angle, expanding the observation range. Universal joints are commonly used angle-changing connection mechanisms and will not be elaborated further.

[0044] It should be noted that the work platform 117 is also equipped with a front control panel 113, which facilitates the operation of the double-arm anchor cable drilling rig 100 by the operator. The front control panel 113 is mainly used to control the drilling actions of the drill arms (first drill arm 107 and second drill arm 118) and the anchor cable tensioning (anchor cable conveyor 130). The rear control panel 125 mainly controls the movement of the walking unit 101, the lifting and lowering of the work platform 117, the lifting and lowering of the outriggers (front support leg 127 and rear support leg 126), the water pump switch, and the tensioning and centralized lubrication of the tracks of the walking unit 101. The two work together to enable the operator to operate the equipment normally for work.

[0045] In one feasible implementation, such as Figure 2 and Figure 3 As shown, the front body 122 and the rear body 116 are connected as a single structure by positioning pins and / or bolts. The rear body 116 is provided with an oil tank pump station 115, which is configured to provide power to each oil cylinder. Anchor cable storage clips 114, a pair of anchor cable storage clips 114 are fixedly installed on the oil tank pump station 115 along the length of the double-arm automatic anchor cable drilling rig 100.

[0046] The oil tank pump station 115 provides hydraulic power to the entire dual-arm automatic anchor cable drilling rig 100, meaning it is typically used to provide hydraulic power to each cylinder. Since the anchor cable is usually 5 to 10 meters long, it cannot be placed in a typical material hopper. Therefore, a pair of anchor cable storage clamps 114 can be installed on the oil tank pump station 115. This allows the anchor cable to be clamped at both ends, improving the stability of the anchor cable storage and preventing the anchor cable from swaying or falling off during the movement of the dual-arm automatic anchor cable drilling rig 100.

[0047] It should be noted that the anchor cable storage clamp 114 may include a base with multiple first grooves. A top plate is hinged to one end of the base, and multiple second grooves are provided on the side of the top plate facing the base. The first and second grooves form a receiving space for accommodating the anchor cable, and the size of the receiving space matches the size of the anchor cable. After the top plate and the base are closed, they can be fixedly connected by bolts or locating pins to clamp the anchor cable. When it is necessary to re-clamp the anchor cable, the bolts or locating pins can be opened, the top plate can be rotated, and the anchor cable can be placed. After the anchor cable is placed, the top plate and the base can be fixed together with bolts or locating pins to clamp the anchor cable. Rubber pads can be placed in the first and second grooves to avoid squeezing the anchor cable and causing damage, and to improve the reliability and stability of the anchor cable clamping.

[0048] In one feasible implementation, such as Figure 2 As shown, the dual-arm automatic anchor cable drilling rig 100 also includes: Cable reel 128 and cable guide 129 are mounted on the rear body 116. Cable reel 128 and cable guide 129 are positioned opposite the oil tank pump station 115. The central passage ladder 123 is located between the oil tank pump station 115 and the cable reel 128. Cable reel 128 and cable guide 129 are configured to reel in and unload the cable of the double-arm automatic anchor cable drilling rig 100. The rear control panel 125 is mounted on the cable reel 128, and the rear control panel 125 is located at one end of the cable reel 128 near the central passageway ladder 123.

[0049] The rear body 116 is also equipped with a cable reel 128 and a cable guide 129. The cable reel 128 and cable guide 129 are positioned opposite the oil tank pump station 115, meaning they are located on either side of the central passageway ladder 123. The cable reel 128, controlled by a motor, can reel in and unelute the cable. In this embodiment, the cable reel 128 can store approximately 100 meters of cable. This cable reeling and unelute mechanism avoids dependence on cable length when the dual-arm automatic anchor cable drilling rig 100 moves forward and backward. The cable guide 129 is located at the outlet of the cable reel 128 and can have two shafts. The cable is wound around the cable reel 128 after passing through the two shafts, resulting in more even cable reeling and unelute.

[0050] It should be noted that a scraper can be installed on the cable guide 129, i.e., the direction in which the axis faces the cable, to scrape off any adhering substances on the cable surface and prevent them from being carried into the cable reel 128, which could cause malfunctions in the cable reel 128. The scraper can be a brush or a rubber sheet, with the brush or sheet facing the cable and interfering with it. Through the interference force and the elastic material of the scraper, adhering substances on the cable can be effectively removed, keeping the cable clean before entering the cable reel 128. Typically, a pair of scrapers are installed opposite each other to improve the efficiency of removing adhering substances from the cable. The scrapers are usually located on the side of the cable guide 129 away from the cable reel 128 to reduce the possibility of adhering substances falling into the cable reel 128.

[0051] Furthermore, the main functions of the rear control panel 125 include controlling the movement of the walking unit 101, raising and lowering the work platform 117, raising and lowering the outriggers (front support leg 127 and rear support leg 126), switching on and off the water pump, and tensioning and lubricating the tracks of the walking unit 101. The front control panel 113 and the rear control panel 125 work together to enable the operator to operate the double-arm automatic anchor cable drilling rig 100 normally.

[0052] In one feasible implementation, such as Figure 3 As shown, a pair of front support legs 127 are provided on the end of the front body 122 away from the rear body 116, and the pair of front support legs 127 are located at both ends of the width direction of the front body 122. A pair of rear support legs 126 are provided on the end of the rear body 116 away from the front body 122, and the pair of rear support legs 126 are located at both ends of the width direction of the rear body 116. Among them, the front support leg 127 and the rear support leg 126 are telescopic support legs.

[0053] It should be noted that at both ends of the front body 122 and the rear body 116, that is, in the width direction of the double-arm automatic anchor cable drilling rig 100, two front support legs 127 and two rear support legs 126 are respectively provided. By extending and retracting the front support legs 127 and the rear support legs 126, stable support can be achieved for the double-arm automatic anchor cable drilling rig 100. When working in a certain fixed position, the stability of the drilling operation of the double-arm automatic anchor cable drilling rig 100 can be increased.

[0054] Understandably, the movement of each hydraulic cylinder and the traveling unit 101 can be controlled via remote control, and the drilling angle and drilling depth can be automatically controlled through chip programming. Functions include automatic drill rod connection according to preset depth, automatic calculation and comparison of drilling depth, automatic drill rod unloading, automatic drill rod return to the storage compartment, automatic anti-blocking during automatic drilling, and manual intervention in feed speed during automatic drilling. Specifically, the dual-arm automatic anchor cable drilling rig 100 possesses highly integrated automated control capabilities, achieving full-dimensional intelligent operation from action execution to process control, greatly improving construction efficiency and accuracy. Each hydraulic cylinder is equipped with a sensor. Hydraulic cylinders without stroke reading requirements are equipped with pressure sensors; when their output pressure reaches a predetermined value, the action is complete. Hydraulic cylinders with stroke reading requirements are equipped with stroke sensors or proximity switches, allowing the automatic program to monitor their stroke in real time and provide the next action requirement at the appropriate position.

[0055] The system supports remote control of all cylinder movements and the movement of the traveling mechanism of the dual-arm automatic anchor cable drilling rig 100. Operators can flexibly control the equipment's basic movements such as steering, movement, and cylinder extension / retraction within a safe area, adapting to the flexible operation needs in complex construction environments. Simultaneously, thanks to the programmed operation of a high-performance microcontroller chip, fully automated control of drilling angle and drilling depth is achieved. By pre-setting construction parameters, the chip can automatically drive the actuator to adjust the posture of the drill arms (first drill arm 107 and second drill arm 118), ensuring that the drilling angle error is controlled within the allowable range. At the same time, it can adjust the drilling speed and feed rate in real time to accurately match the preset depth requirements, avoiding deviations caused by manual operation. To ensure the precise execution of each action, the system is equipped with dedicated sensors for all cylinders, employing differentiated detection schemes based on the control requirements of different actions: for cylinders without stroke reading requirements, high-precision pressure sensors are installed. When the hydraulic cylinder drive mechanism reaches the preset position, the pressure inside the cylinder rises sharply and reaches the preset threshold. The sensor captures this pressure signal in real time and feeds it back to the control system, which serves as the basis for determining whether the action is in place, ensuring the reliable completion of actions such as cylinder locking and mechanism positioning. For hydraulic cylinders that require real-time monitoring of the stroke, a stroke sensor or proximity switch is configured. The stroke sensor can dynamically collect precise displacement data of the cylinder's extension and retraction, while the proximity switch can trigger a signal when the cylinder reaches a specific position. Both devices can transmit the stroke information to the automatic control program in real time. The program analyzes the data to determine the current progress of the action and automatically issues the next action command when the preset position is reached (such as the preset drilling depth or the critical position for drill rod connection and disconnection), achieving seamless process connection.

[0056] The system deeply integrates the entire drilling process requirements and has developed a series of automated functions covering the entire process from drilling initiation to drill rod retrieval: Automatic rod connection and depth control: When the drilling depth reaches the effective length of a single drill rod, the system detects depth data through a stroke sensor, automatically stops drilling, and executes the rod connection process—driving a robotic arm to grab a new drill rod, precisely aligning it with the drill rod threads and locking it in place. Simultaneously, it automatically calculates the total drilling depth, compares it with the preset construction depth in real time, and dynamically adjusts subsequent drilling parameters; Automatic rod unloading and storage: After drilling is completed, the system automatically disassembles the drill rod according to the reverse process. A pressure sensor confirms the drill rod locking mechanism is released, and then the robotic arm transports the disassembled drill rod to a dedicated storage compartment for orderly storage, avoiding safety hazards and efficiency losses caused by haphazardly stacked drill rods; Automatic anti-clogging. Drilling Protection: During automatic drilling, the system monitors parameters such as drilling pressure, torque, and feed rate in real time. Combined with a preset geological adaptation model, it determines whether there is a risk of drill blockage in the hole. When abnormal parameters are detected (such as a sudden increase in torque or a decrease in feed rate), the anti-blocking program is automatically activated. This involves adjusting the drilling direction, pausing feed, or reversing rotation to promptly clear accumulated cuttings in the hole, ensuring smooth drilling. Manual Intervention for Feed Rate: Considering the possibility of temporary parameter adjustments under complex geological conditions (such as hard rock or fractured strata), the system includes a manual intervention interface. Operators can manually adjust the feed rate during automatic drilling via remote control or control panel without interrupting the automatic program. This ensures flexibility in special working conditions without affecting the overall automated process. The control system of this application, through a dual control mode of "remote + automatic," precise sensing and detection technology, and full-process automation, achieves high efficiency, precision, and safety in drilling operations, significantly reducing manual labor intensity. It is particularly suitable for large-scale, high-precision drilling scenarios.

[0057] Meanwhile, the dual-arm automatic anchor cable drilling rig 100 of this application has a large working platform 117 and a worktable flip-up plate 110, expanding the working area. It also has a central passage ladder 123 hinged to the working platform 117, eliminating the need for manual unloading of drill rods. The drill arms (first drill arm 107 and second drill arm 118) automatically complete the process, resulting in a tighter connection of the drill rods, better straightness, and better prevention of hole collapse due to drilling deviation. This application also includes an anchor cable conveyor 130, making post-drilling support work more convenient and improving the efficiency of support work.

[0058] The drill arm pipe rack 120 is mainly assembled from steel plates. Its lower part is located inside the pair of drill arm left-right adjustment cylinders 119 and is hinged to the sliding box telescopic arm 103. Its upper part is hinged to the outer shell of the drill arms (first drill arm 107 and second drill arm 118). It primarily houses some of the hydraulic oil pipes of the double-arm automatic anchor cable drilling rig 100, serving a storage function. When the drill arms (first drill arm 107 and second drill arm 118) are adjusted left-right, the pipelines can be constrained, allowing the hydraulic oil pipes to move with the left-right adjustment of the drill arms, preventing interference between the pipelines and mechanical components and affecting the normal operation of the equipment.
