Abstract
Description
Technical Field
[0001] This solution belongs to the technical field of roadway support equipment, specifically involving an advanced support device. Background Technology
[0002] Pre-support is a technique used during tunnel excavation to ensure the stability and safety of the surrounding rock by pre-supporting it. In mining, especially in deep or geologically complex areas, the surrounding rock may lose its original support due to excavation, leading to dangerous situations such as roof collapse or sidewall slippage. To prevent this, pre-support involves installing support structures, such as anchor bolts and pipe roofs, before excavation to enhance the integrity and load-bearing capacity of the surrounding rock, thereby effectively controlling its deformation and failure. By drilling holes and installing anchor bolts in the surrounding rock, the loose and fractured sections of the rock can be effectively fixed together to form a unified whole, thus improving the self-supporting capacity and stability of the surrounding rock.
[0003] During the installation of rock bolts, drilling is required in the surrounding rock, typically using a roadway rock bolt drilling rig. A roadway rock bolt drilling rig is a device specifically designed for drilling operations in narrow roadway environments. It offers high mobility and flexibility, enabling drilling within limited space to achieve advanced support and ensure the safety and efficiency of mining operations.
[0004] A tunnel monorail drilling rig and its construction method are disclosed in the existing publication (announcement) number CN108999570A. The tunnel drilling rig includes a suspension device for being installed at the top of the tunnel; a suspension box body installed below the suspension device and slidably or rollingly connected to the suspension device; a drill arm device installed on the suspension box body for drilling operations in the tunnel; and a machine stabilization support device installed on the suspension box body. Both ends of the machine stabilization support device are telescopic structures for forming support against the two side walls opposite to the tunnel.
[0005] For example, in the aforementioned tunnel drilling rig, when the drill rod is extended to a considerable length, its center of gravity moves away from the support point. This increases the bending moment generated by the drill rod's own weight and external vibrations, making it more prone to bending and vibration. Furthermore, changes in the drilling angle alter the direction and magnitude of the contact force between the drill rod and the surrounding rock, further increasing the drill rod's instability. Under these circumstances, the swaying of the drill rod not only affects the accuracy and quality of the drilling but can also lead to damage to the drill rod, malfunctions in the drilling equipment, and even threaten the safety of construction workers. Utility Model Content
[0006] The purpose of this solution is to provide an advanced support device to address the instability caused by excessively long drill pipe extension in existing roadway drilling rigs.
[0007] To achieve the above objectives, this solution provides an advanced support device, including support equipment and a drilling rig that cooperates with the support equipment. The drilling rig includes a frame body and a traveling mechanism, a support mechanism, a drive mechanism, and a drilling mechanism mounted on the frame body. It also includes a support assembly mounted on the support mechanism, the support assembly comprising:
[0008] A support platform, which is mounted on the support mechanism;
[0009] A first support arm is mounted on a support platform and has a through groove.
[0010] The clamping arms consist of two sets of clamping arms, which are symmetrically arranged on the first support arm. The clamping arms are used to clamp and fix the drill rod of the drilling mechanism.
[0011] A drive unit is used to drive two sets of clamping arms to clamp the drill rod.
[0012] The principle of this solution is as follows: the support equipment is existing technology and will not be elaborated upon here. This solution involves setting a support platform on the support mechanism of the drilling rig, and installing a first support arm on the support platform. A through slot in the support arm is used to accommodate the drill rod, and a clamping arm can clamp and fix the drill rod of the drilling mechanism. Under the control of the drive unit, the clamping arm can apply an appropriate clamping force to the drill rod, ensuring it is clamped during extension and reducing swaying and bending caused by excessive extension of the drill rod.
[0013] The benefits of this solution are: by setting up support components, it solves the problem of swaying and bending that easily occurs when the drill rod extends too far, ensuring the accuracy and quality of drilling, reducing the risk of equipment damage caused by drill rod instability, and improving construction safety.
[0014] Furthermore, the driving unit is a cylinder, and the piston rod of the cylinder is fixedly connected to the clamping arm; the contact surface between the clamping arm and the drill rod is provided with a silicone layer, and the contact surface is "V" shaped.
[0015] The principle and effect of this solution are as follows: the extension and retraction of the piston rod of the cylinder drives the movement of the clamping arms, thereby causing the two sets of clamping arms to move relative to or towards each other, thus clamping the drill rod and preventing unstable swaying caused by an excessively long drill rod. The addition of a silicone layer increases the friction of the clamping arms and acts as a buffer, protecting the drill rod. The "V"-shaped contact surface ensures a uniform distribution of clamping force.
[0016] Furthermore, the support assembly also includes a second support arm, the middle of which is rotatably connected to the support platform. Hydraulic cylinders are symmetrically arranged on both sides of the second support arm, the cylinder body of which is rotatably connected to the support platform, and the piston rod of which is rotatably connected to the second support arm.
[0017] The principle and effect of this solution are as follows: During drilling, the drilling angle changes, which in turn causes the drill rod angle to change. Therefore, a second support arm is installed to follow the angle changes of the drill rod. In this solution, the extension and retraction of the piston rod of the hydraulic cylinder causes the second support arm to rotate accordingly. This allows the second support arm to adjust to the angle changes of the drill rod, ensuring effective support for the drill rod during drilling operations at different angles and preventing drill rod offset or vibration caused by angle changes.
[0018] Furthermore, a guide ring is provided between the first support arm and the second support arm. The guide ring is located on the support platform and has a semi-circular structure. The guide ring has the same radius of curvature as the outer wall of the drill rod.
[0019] The principle and effect of this solution are as follows: by setting a semi-circular guide ring with the same radius of curvature as the outer wall of the drill pipe between the first support arm and the second support arm, a stable guide path is provided for the drill pipe, so that the first clamping arm and the second clamping arm can stably clamp the drill pipe.
[0020] Furthermore, the traveling mechanism is a tracked traveling mechanism, which is located on both sides of the bottom of the vehicle frame body. The traveling mechanism is rotatably connected to the vehicle frame body and is used to drive the vehicle frame body to travel along the alleyway.
[0021] The principle and effect of this scheme are as follows: by setting tracked walking mechanisms on both sides of the bottom of the main frame and rotatably connecting them to the main frame, the entire frame can move and rotate within the tunnel.
[0022] Furthermore, the support mechanism includes a first support frame, a second support frame, and a hydraulic support assembly. One end of the first support frame is rotatably connected to one end of the second support frame. The hydraulic support assembly includes a first hydraulic cylinder, a second hydraulic cylinder, and a third hydraulic cylinder. The cylinder body of the first hydraulic cylinder is rotatably connected to the vehicle frame body, and the piston rod of the first hydraulic cylinder is rotatably connected to the first support frame. The cylinder body of the second hydraulic cylinder is rotatably connected to the vehicle frame body, and the piston rod of the second hydraulic cylinder is rotatably connected to the cylinder body of the first hydraulic cylinder. The cylinder body of the third hydraulic cylinder is rotatably connected to the vehicle frame body, and the piston rod of the third hydraulic cylinder is rotatably connected to the first support frame.
[0023] The principle and effect of this scheme are as follows: the angle of the drill rod is adjusted by the coordinated action of multiple hydraulic cylinders in the hydraulic support assembly. The first hydraulic cylinder directly supports the first support frame, the second hydraulic cylinder provides additional support force through its connection with the first hydraulic cylinder body, and the third hydraulic cylinder provides further support to the first support frame. Through this arrangement, the drill rod can move at any point in three-dimensional space along the X, Y, and Z axes, thereby allowing the drill rod to drill holes at any location in the tunnel.
[0024] Furthermore, the driving mechanism includes a first driving component and a second driving component; both the first driving component and the second driving component are mounted on a first support frame. The first driving component includes a slide table, a linear motor, and a slide rail. The slide rail is mounted on the first support frame, and the slide table is slidably mounted on the slide rail. The linear motor is used to drive the slide table to move along the slide rail. A support platform is provided on the slide table, and the drill rod is mounted on the support platform.
[0025] The principle and effect of this solution are as follows: the linear motor drives the slide table to move along the slide rail, thereby moving the drill rod on the bearing platform on the first support frame, thus controlling the extension and retraction of the drill rod, and thus controlling the drilling depth.
[0026] Furthermore, the second drive assembly includes a fourth hydraulic cylinder, the cylinder body of which is fixedly connected to the first support frame, and the piston rod of which is rotatably connected to the first support frame.
[0027] The principle and effect of this solution are as follows: by extending and retracting the piston rod of the fourth hydraulic cylinder, and cooperating with the hydraulic support assembly, the elevation and tilt angles of the drill rod can be controlled, thereby adapting to different drilling angle requirements.
[0028] Furthermore, the drilling mechanism includes a casing, a first drive motor, and a second drive motor; the casing is mounted on a support platform, the drill rod is mounted inside the casing, the drill rod body has a auger structure, the drill bit of the drill rod is an eccentric drill bit, and the first drive motor and the second drive motor are connected to the free end of the rod body via a coupling.
[0029] The principle and effect of this scheme are as follows: through the coordinated operation of the first and second drive motors, the drill rod with the auger structure rotates within the casing, while the eccentric drill bit performs drilling operations. The auger structure of the drill rod effectively transports drill cuttings, reduces clogging, and improves drilling efficiency. The eccentric drill bit helps generate greater cutting force during drilling, making drilling faster.
[0030] Furthermore, the first drive motor is a forward-rotating motor, the second drive motor is a reverse-rotating motor, and both the first drive motor and the second drive motor are electrically connected to the controller, which is electrically connected to the drive mechanism and the support mechanism.
[0031] The principle and effect of this scheme are as follows: the first drive motor drives the drill rod to drill forward, and the second drive motor drives the drill rod to reverse and pull the drill rod out of the hole. The controller controls and schedules the rotation of the first drive motor and the second drive motor, and controls the drive mechanism and the support mechanism to cooperate with the first drive motor and the second drive motor, thereby controlling the depth and angle of the drilling.

The support equipment includes existing technologies such as anchor bolts and anchor cables. The drilling rig includes a frame body 1 and a traveling mechanism 2, a support mechanism 3, a drive mechanism 4, and a drilling mechanism 5 mounted on the frame body 1.
[0042] Please see Figure 1 The traveling mechanism 2 is a tracked traveling mechanism 2, which is located on both sides of the bottom of the frame body 1. The traveling mechanism 2 is rotatably connected to the frame body 1 and is used to drive the frame body 1 to travel along the roadway. By setting the tracked traveling mechanism 2 on both sides of the bottom of the frame body 1 and rotatably connecting the traveling mechanism 2 to the frame body 1, the movement and rotation of the entire frame body 1 in the roadway can be realized.
[0043] Please see Figures 1-3 The support mechanism 3 includes a first support frame 32, a second support frame 34, and a hydraulic support assembly 33. One end of the first support frame 32 is rotatably connected to one end of the second support frame 34. The hydraulic support assembly 33 includes a first hydraulic cylinder 331, a second hydraulic cylinder 332, and a third hydraulic cylinder 333. The cylinder body of the first hydraulic cylinder 331 is rotatably connected to the frame body 1, and the piston rod of the first hydraulic cylinder 331 is rotatably connected to the first support frame 32. The cylinder body of the second hydraulic cylinder 332 is rotatably connected to the frame body 1, and the piston rod of the second hydraulic cylinder 332 is rotatably connected to the cylinder body of the first hydraulic cylinder 331. The cylinder body of the third hydraulic cylinder 333 is rotatably connected to the frame body 1, and the piston rod of the third hydraulic cylinder 333 is rotatably connected to the first support frame 32. The angle of the drill rod 51 is adjusted by the coordinated action of multiple hydraulic cylinders in the hydraulic support assembly 33. The first hydraulic cylinder 331 directly supports the first support frame 32, the second hydraulic cylinder 332 provides additional support force through its connection with the cylinder body of the first hydraulic cylinder 331, and the third hydraulic cylinder 333 provides further support to the first support frame 32. This configuration allows the drill rod 51 to move at any point in three-dimensional space along the X, Y, and Z axes, enabling it to drill holes at any location within the tunnel.
[0044] Please see Figure 2 and Figure 3The drive mechanism 4 includes a first drive assembly 41 and a second drive assembly 42. Both the first drive assembly 41 and the second drive assembly 42 are mounted on a first support frame 32.

The slide rail 412 is mounted on the first support frame 32, and the slide table 411 is slidably mounted on the slide rail 412. The linear motor drives the slide table 411 to move along the slide rail 412. A support platform 413 is mounted on the slide table 411, and the drill rod 51 is mounted on the support platform 413. By driving the slide table 411 to move along the slide rail 412 through the linear motor, the drill rod 51 on the support platform 413 moves on the first support frame 32, thereby controlling the extension and retraction of the drill rod 51, and thus controlling the drilling depth of the drill rod 51. The second drive assembly 42 includes a fourth hydraulic cylinder 421. The cylinder body of the fourth hydraulic cylinder 421 is fixedly connected to the first support frame 32, and the piston rod of the fourth hydraulic cylinder 421 is rotatably connected to the first support frame 32. By extending and retracting the piston rod of the fourth hydraulic cylinder 421, and cooperating with the hydraulic support assembly 33, the elevation and tilt angles of the drill rod 51 are controlled, thereby adapting to different drilling angle requirements.
[0045] Please see Figure 6 The drilling mechanism 5 includes a casing 52, a first drive motor 53, and a second drive motor 54. The casing 52 is mounted on a support platform 413, and the drill rod 51 is located inside the casing 52. The rod body 511 of the drill rod 51 has a auger structure, and the drill bit 512 of the drill rod 51 is an eccentric drill bit. The eccentric drill bit helps to generate greater cutting force during drilling, making drilling faster. The first drive motor 53 and the second drive motor 54 are connected to the free end of the rod body 511 via a coupling. The first drive motor 53 is a forward rotation motor, and the second drive motor 54... As a reversible motor, the first drive motor 53 and the second drive motor 54 are both electrically connected to the controller. The controller is electrically connected to the drive mechanism 4 and the support mechanism 3. The first drive motor 53 drives the drill rod 51 to drill in the forward direction, and the second drive motor 54 drives the drill rod 51 to reverse and pull the drill rod 51 out of the hole. The controller controls and schedules the rotation of the first drive motor 53 and the second drive motor 54, and controls the drive mechanism 4 and the support mechanism 3 to cooperate with the first drive motor 53 and the second drive motor 54, thereby controlling the depth and angle of the drilling.
[0046] Please see Figures 1-5It also includes a support assembly 31 mounted on the first support frame 32. The support assembly 31 includes a support platform 311, a first support arm 312, a clamping arm 313, and a cylinder 314. The support platform 311 is mounted on the support mechanism 3, and the first support arm 312 is mounted on the support platform 311. The first support arm 312 has a through groove 3121, and the sleeve 52 of the drill rod 51 is located in the through groove 3121. There are two sets of clamping arms 313. Arms 313 are symmetrically arranged on the first support arm 312. The clamping arm 313 is used to clamp the sleeve 52 of the drill rod 51 of the drilling mechanism 5. The piston rod of the cylinder 314 is fixedly connected to the clamping arm 313. The contact surface between the clamping arm 313 and the drill rod 51 is provided with a silicone layer and the contact surface is "V" shaped. The silicone layer increases the friction of the clamping arm 313 and plays a buffering role to protect the drill rod 51. The "V" shaped contact surface makes the clamping force evenly distributed.
[0047] The support assembly 31 also includes a second support arm 315. The structure of the second clamping arm 315 is the same as that of the first clamping arm 312, but the middle part of the second support arm 315 is rotatably connected to the support platform 311. Two hydraulic cylinders 316 are symmetrically arranged on both sides of the second support arm 315. The cylinder body of the hydraulic cylinder 316 is rotatably connected to the support platform 311, and the piston rod of the hydraulic cylinder 316 is rotatably connected to the second support arm 315. A guide ring 317 is provided between the first support arm 312 and the second support arm 315. The guide ring 317 is located on the support platform 311 and has a semi-circular structure. The radius of curvature of the guide ring 317 is the same as that of the outer wall of the drill rod 51. By setting a semi-circular guide ring 317 with the same radius of curvature as the outer wall of the sleeve 52 of the drill rod 51 between the first support arm 312 and the second support arm 315, a stable guiding path is provided for the drill rod 51, so that the first clamping arm 312 and the second clamping arm 315 can stably clamp the drill rod 51.
[0048] Specific working principle: A support platform 311 is set on the first support frame 32 of the drilling rig, and a first support arm 312 is installed on the support platform 311. A through slot 3121 on the first support arm 312 is used to accommodate the drill rod 51. The clamping arm 313 can clamp and fix the drill rod 51 of the drilling mechanism 5. The extension and retraction of the piston rod of the cylinder 314 drives the clamping arm to move, thereby causing the two sets of clamping arms 313 to move relative to or towards each other, thus clamping the drill rod 51 and preventing the drill rod 51 from being too long and causing unstable shaking. At the same time, the extension and retraction of the piston rod of the hydraulic cylinder 316 causes the second support arm 315 to rotate accordingly, thereby allowing the second support arm 315 to adjust with the angle change of the drill rod 51, so that the drill rod 51 can be effectively supported in drilling operations at different angles, avoiding the displacement or vibration of the drill rod 51 caused by angle changes.
[0049] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
