Description

Technical Field

[0001] The present application relates to the technical field of coal mine tunnel support drilling, and in particular to a positioning guide device and an anchor rod and cable drilling vehicle. Background Art

[0002] In recent years, with the increasing scope and breadth of coal resource mining, complex geological conditions and high ground stress environment have made it increasingly difficult to control the surrounding rock of the tunnel. With the continuous advancement of science and technology, the coal tunnel support method has gradually developed from passive support forms such as steel support and retractable support to active support forms such as pure anchor support, anchor mesh support, and anchor and cable combined support. A large number of research results have been achieved, and a lot of valuable experience has been accumulated in engineering practice. Coal mining tunnels need to drive anchors or cables into the rock mass, and then anchor them tightly to reinforce the tunnel support: At present, the machine tunnel roof is supported by resin anchor rods, anchor cables, and anchor nets. The spacing between anchor rods and rows is about 800mm, and the spacing between anchor cables and rows is about 2400mm. The upper and lower walls of the machine tunnel are supported by resin anchor rods and anchor nets, and the spacing between anchor rods and rows is 800mm. The diameter of the anchor rod is about 18mm and the length is about 1800mm; the diameter of the anchor cable is about 17.8mm and the length is about 5200mm. During the anchor rod construction, the MQT-130 anchor rod machine is used to drill the anchor rod eye. The diameter of the anchor rod eye hole construction is 28mm, and the depth of the anchor rod eye is 50-100mm shorter than the full length of the anchor rod body. The coal and rock powder in the drilled anchor hole must be cleaned, free of water and debris. When installing the resin anchor rod, use the MSK-2350 resin drug roll to continuously stir at a uniform speed for 8~15s and stop. After the stirring stops, wait for 41~90s until the gel is formed and then withdraw the anchor rod drilling rig. After the waiting time of the anchoring agent reaches 5 minutes, the anchor drill can be used to tighten the nut until the plastic pad is pushed out of the tail of the anchor, the tray is close to the wall, and the anchor is exposed to the nut for 10mm~50mm; the pre-tightening torque of the anchor nut shall not be less than 120N.m; and shall not be greater than 150N.m. It can be seen from this that the number of holes required for tunnel support is huge, and manual handheld drilling rigs are mostly used for drilling, which has low drilling efficiency, and the drilling positioning direction is prone to deviation, and the anchoring effect does not meet the design requirements; at the same time, when workers perform a large number of drilling operations, they consume a lot of physical energy, and the directional drilling effect is poor, which greatly affects the construction progress and cannot meet the directional drilling needs.

DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0019] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should be understood by people with ordinary skills in the field to which this disclosure belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] In order to facilitate the understanding of the positioning and guiding device and the anchor cable drilling vehicle provided in the embodiment of the present application, the application scenario is first explained. The positioning and guiding device and the anchor cable drilling vehicle are mainly used for coal mine tunnel support drilling. At present, the machine tunnel roof is supported by resin anchors, anchor cables, and anchor nets. The anchor spacing and row spacing are both about 800mm, and the anchor cable spacing and row spacing are both about 2400mm; the upper and lower sides of the machine tunnel are supported by resin anchors and anchor nets, and the anchor spacing and row spacing are both 800mm. The diameter of the anchor rod is about 18mm and the length is about 1800mm; the diameter of the anchor cable is about 17.8mm and the length is about 5200mm. During the anchor construction, the MQT-130 anchor machine is used to drill the anchor eye. The diameter of the anchor eye hole construction is 28mm, and the depth of the anchor eye is 50-100mm shorter than the full length of the anchor rod body. The coal and rock powder in the drilled anchor hole must be cleaned, free of water and debris. To install the resin anchor, use the MSK-2350 resin drug roll to continuously stir at a uniform speed for 8 to 15 seconds before stopping. After the stirring stops, wait for 41 to 90 seconds until the gel is formed and then withdraw the anchor drill. The anchor drill can be used to tighten the nut after the waiting time of the anchor agent reaches 5 minutes, until the plastic pad is pushed out of the tail of the anchor, the tray is close to the wall, and the anchor is exposed to the nut for 10mm to 50mm; the pre-tightening torque of the anchor nut shall not be less than 120N.m; and shall not be greater than 150N.m. It can be seen from this that the number of holes required for tunnel support is huge, and manual handheld drills are mostly used for drilling, which has low drilling efficiency, and the drilling positioning direction is prone to deviation, and the anchoring effect does not meet the design requirements; at the same time, when workers perform a large number of drilling operations, they consume a lot of physical energy, and the directional drilling effect is poor, which greatly affects the construction progress and cannot meet the directional drilling needs. In view of this, the positioning guide device and anchor rod and cable drilling vehicle in this application can perform multi-station operations by accurately adjusting the anchoring spacing, thereby improving the drilling speed, and multi-hole collaboration ensures accurate drilling positioning, reduces construction difficulty, reduces workload, and speeds up the tunnel support process.

[0021] refer to Figure 1 , Figure 1 The structural diagram of the positioning and guiding device. The positioning and guiding device provided in the embodiment of the present application includes a multi-directional adjustment component 100 connected to a mobile carrier and a positioning component 200 connected to the multi-directional adjustment component 100; the positioning and guiding device in the present application can match the corresponding mobile carrier according to the height and width requirements of the tunnel, and the mobile carrier needs to have a stable bottom foundation to bear the reverse impact force generated during multi-hole collaborative drilling; the worker controls the mobile carrier to be located at the anchor hole opening position, and the multi-directional adjustment component 100 adjusts the corresponding drilling angle according to the design requirements, and pushes the positioning component 200 to achieve multi-hole synchronous drilling, which greatly improves the construction efficiency and the stability of the drilling guide.

[0022] The multi-directional adjustment component 100 in the present application includes a lifting device 110; the lifting device 110 is located on a mobile carrier, and the lifting device 110 uses a hydraulic telescopic rod. During the lifting process, the lifting device 110 can make corresponding adjustments to the anchor hole positioning areas at different heights, thereby greatly meeting the height requirements and being suitable for different tunnels. The multi-directional adjustment component 100 also includes a multi-directional adjustment arm. The multi-directional adjustment arm in the present application uses a three-axis robotic arm. Of course, when drilling holes for more complex working conditions, a five-axis robotic arm can also be used. The multi-directional adjustment arm locates the anchor hole opening points through system scanning, and automatically adjusts or manually adjusts remotely. These are all commonly used technical means in three-axis robotic arms, and will not be described in detail here.

[0023] The multi-directional adjustment arm includes a first arm section 130, a large arm section 140 and a terminal arm section 150; wherein, a telescopic dust cover 160 is mounted at the axial joint between the large arm section 140 and the terminal arm section 150. The three-axis mechanical arm is used as the precise adjustment body, which greatly improves the anchor hole drilling accuracy. In addition, during the drilling process, part of the dust generated is shielded by the telescopic dust cover 160, which improves the use environment of the multi-directional adjustment arm.

[0024] In the present application, the top of the lifting device 110 is fixedly equipped with a positioning plate 120, and the first arm section 130 of the multi-directional adjustment arm is rotatably connected to the positioning plate 120 through a bearing 121. Circumferential rotation is achieved, which is convenient for adjustment according to different working conditions. A servo motor is installed in the positioning plate 120, and the first arm section 130 is driven by the motor to rotate circumferentially, which can effectively meet the construction requirements. In the process of anchor hole drilling, upward inclined drilling is often used, so that the anchor rod has a higher anchoring effect after installation. To this end, in the present application, the upper arm 140 and the last arm 150 cooperate with each other to adjust the angle, and the overall preliminary adjustment and positioning are accurate.

[0025] At the same time, combined Figure 2 and Figure 3 As shown in the figure, the telescopic device 170 is installed on the end arm 150 in the present application, and the telescopic device 170 is used for linear motion to reduce the position deviation caused by the previous manual propulsion process, and the telescopic device 170 is a multi-section hydraulic telescopic rod, and the extension length of the telescopic device 170 is not less than 1800mm. The propulsion stroke is met, and the larger range is convenient for construction.

[0026] At the same time, the positioning assembly 200 in the present application is fixedly installed at the end of the telescopic device 170. The positioning assembly 200, as the distribution adjustment body in the present application, makes corresponding adjustments according to the anchor point requirements of the preset distribution, and two drilling rigs 300 or four drilling rigs 300 can be used for synchronous operation, thereby realizing multi-point collaborative operation. It needs to be specifically explained that the drilling rig 300 in the present application can use the same model of drilling rig 300, and replace different drill bits according to the drilling requirements, or use anchor drilling rigs and high-power anchor cable drilling rigs respectively. The telescopic device 170 provides a relatively stable linear propulsion force according to the inclination angle to reduce the loss of the drilling rig.

[0027] For example, when the anchor rod spacing and row spacing are both 800 mm, by locating the anchor rod hole positions, the positioning assembly 200 is used to adjust the distribution of multiple drilling rigs so that two or four drilling rigs are respectively located at the drilling points. After the drilling rigs are started, they are slowly pushed forward by the telescopic device 170 to quickly realize the synchronous formation of two or four hole positions, and during the drilling process, the drilling inclination in the same area can be kept consistent, and the anchor spacing between each other is in the optimal state, thereby enhancing the anchoring effect.

[0028] Specifically, in the present application, four drilling rigs are preferably used for synchronous and cooperative operation; the positioning assembly 200 includes a power disk 210 and a gear disk 220 fixedly connected to the power disk 210; the gear disk 220 is cross-distributed with slide grooves 221, and a drilling rig assembly plate 222 is slidably mounted inside each slide groove 221; the gear disk 220 is also layered with four cross-distributed racks 212, and any two racks 212 of the same layer are arranged oppositely and move synchronously in opposite directions; each rack 212 is fixedly connected to the corresponding drilling rig assembly plate 222, and the gear disk 220 is internally rotatably connected with a double-layer gear that simultaneously meshes with four racks 212; the power disk 210 is fixedly connected to the telescopic device 170, and the power disk 210 is internally equipped with a driving motor 211 for driving the double-layer gear to rotate; the four drilling rig assembly plates 222 are all flush with the surface of the gear disk 220. It has synchronous coordination.

[0029] It can be seen from the above structure that, through the rotation of the double-layer gear, the four racks 212 are synchronously meshed and telescopically moved, so that the center of the drill rig on each drill rig assembly plate 222 is consistent with the center of the gear plate 220; when the anchor rod spacing and the row spacing are both 800mm, the spacing between the two drill rigs on the same straight line is also 800mm; for special locations, when it is impossible to synchronize and coordinate four drill holes, two or three of the drill rigs can be used to operate, to ensure that the drill rod has a mutual check and balance effect during drilling, and to ensure the guiding stability during drilling.

[0030] At the same time, the center of the gear plate 220 in the present application is provided with a drilling rig installation position 223. The drilling rig installation hole position is used to adapt to the installation of the anchor cable. The required depth of the anchor cable installation drilling hole is relatively large, and it is very easy to deviate; for this reason, the drilling rig used for anchor cable installation is installed at the center position of the gear plate 220 in the present application. This position greatly ensures the stability of drilling, and the drill bit is positioned on the two opposite drilling rig installations on the matching drilling rig installation plate, which can ensure that the angle is always within the standard range during the drilling process. Optional installation is performed according to different construction scenes or construction spacings. When the multi-section drill rod is deep, the drilling rig on the drilling rig installation plate no longer generates drilling work, but only provides a propulsion and guidance function. These are all technologies that can be actually obtained by people in this field, and will not be described in detail here.

[0031] In the present invention, multiple machines are used to work in coordination, and the spacing between each machine position is adjusted during the rotation of the double-layer gear to meet the construction requirements; the multi-directional adjustment arm performs multi-directional precise adjustment according to the anchor hole distribution requirements and the inclined drilling requirements, and the same telescopic device 170 is used for slow advancement. During the drilling process, multiple drill rods can achieve the effect of mutual coordinated positioning, and simultaneously meet the precise guidance of multiple anchor holes. Its precise positioning and construction convenience are both outstanding, which speeds up the support progress and reduces the construction cost.

[0032] In addition, in order to better improve the construction accuracy and speed up the construction progress, the present application also provides an anchor cable drilling vehicle; Figure 4 As shown in , the anchor rod and cable drilling vehicle includes a drilling vehicle body, and the drilling vehicle body adopts a crawler body to meet different working conditions. The drilling vehicle body has a rotating table 10, the bottom of the rotating table 10 is equipped with track wheels 11, and a plurality of spirit levels 13 are installed on the rotating table 10. Perform preliminary leveling to meet different working conditions. A bulldozer 12 is installed at either end of the drilling vehicle body. It is convenient to clean up the construction site. First of all, at the initial stage of work, the drilling vehicle body is ensured to be located on a relatively flat lane surface, and a bulldozer 12 is provided to level the ground, and the spirit level 13 can visually check the flatness to avoid the ground settlement caused by the relative pressure generated by the drilling hole in the later stage and cannot be adjusted in time.

[0033] The drilling vehicle body is equipped with a positioning guide device, which is slidably mounted on the rotating table 10, and the rotating table 10 is equipped with a driving system 15 for driving the sliding displacement of the positioning guide device; the rotating table 10 is provided with a mounting groove 14 along the length direction, and a mounting table is slidably mounted inside the mounting groove 14, and the bottom of the lifting device 110 is fixedly mounted on the mounting table; the driving system 15 is a hydraulic telescopic rod, and the driving system 15 is connected to one end of the mounting table. It can be adjusted in multiple directions to meet the construction needs.

[0034] At the same time, in order to better cope with the gravity pressure caused by the inclined upward drilling, the drilling vehicle body in the present application is equipped with a flexible support and positioning tube 17 on the rotating table 10; it should be specifically explained that the flexible support and positioning tube 17 in the present application has a certain resilience toughness, and irregular bending occurs during the continuous adjustment of the position of the multi-directional adjustment component 100. Figure 5 As shown in the figure, the support and positioning tube 17 includes: a double-walled corrugated tube 1701 and a flexible sleeve 1702 sleeved inside the double-walled corrugated tube 1701; the magnetorheological fluid is filled in the flexible sleeve 1702. It is bendable and has a certain toughness. At the same time, after irregular bending, the magnetorheological fluid changes its characteristics to achieve auxiliary support and offset part of the vibration force, ensuring that the drilling guidance is accurate and reliable.

[0035] When the supporting effect is realized specifically, a positioning clamp ring 18 is installed at the connection between the last arm 150 and the telescopic device 170. The positioning clamp ring 18 is made according to the shape of the connection and is locked with bolts. A rotating ring 19 is rotatably connected to the positioning ring, and the top of the supporting positioning tube 17 is connected to the rotating ring 19. The rotating ring 19 can offset the entanglement caused by the circumferential rotation of the upper arm 140, so that the supporting positioning tube 17 is always located at the bottom for support.

[0036] In the specific implementation of flexible bending and having a certain auxiliary strength support, the interior of the support positioning tube 17 in the present application is filled with magnetorheological fluid, and the rotating table 10 is provided with an electromagnetic generator 16 electrically connected to the magnetorheological fluid; the anchor rod and anchor cable drilling vehicle also includes a drilling rig fixedly connected to four drilling rig assembly plates 222 and a drilling rig installation position 223; when the positioning guide device adjusts the positioning hole position, the electromagnetic generator 16 is not electrically connected to the magnetorheological fluid, and the magnetorheological fluid is a Newtonian fluid; when the telescopic device 170 propels the drilling rig for synchronous drilling operations, the electromagnetic generator 16 is electrically connected to the magnetorheological fluid, and the magnetorheological fluid is a Bingham fluid.

[0037] It can be seen that during the initial positioning, the magnetorheological fluid inside the supporting positioning tube 17 exhibits the characteristics of a low-viscosity Newtonian fluid, and in the process of continuous adjustment of the position of the multi-directional adjustment component 100, it is subjected to the pressure and produces irregular bending. When the telescopic device 170 starts to advance the drilling, the magnetorheological fluid presents a high-viscosity, low-fluidity Bingham fluid at the millisecond level, which has a stable supporting effect and can reduce the vibration according to the regionality of the rock formation being drilled.

[0038] In the present application, the drilling vehicle body is used to reduce human intervention, and the support positioning tube 17 is used to assist in support, thereby offsetting the vibration force during the drilling process, making the anchor hole drilling angle more accurate, greatly improving the support progress, and reducing the construction cost.
