Description

Technical Field

[0001] This invention relates to the field of drilling technology, specifically to a drilling rig-based drilling device for rock drilling. Background Technology

[0002] A rock drilling rig is a mechanized equipment for geotechnical engineering that integrates rock drilling, positioning, and movement. It mainly consists of a drill arm, drilling mechanism, positioning system, and chassis, and automates drilling operations through hydraulic / electric drive. It is widely used in mining, tunnel excavation, road and bridge slope protection, and water conservancy project foundation pit construction, for drilling operations such as blasting holes, anchor bolt holes, and grouting holes. It significantly improves drilling efficiency and accuracy while reducing manual labor intensity, making it a core piece of equipment for large-scale geotechnical engineering construction. However, existing rock drilling rigs operate with the drill bit directly contacting the rock surface. The high-frequency vibrations generated during drilling can easily loosen the rock surface, causing surface rock dust to fall into the hole, affecting drilling accuracy and subsequent processes. Furthermore, existing devices lack effective rock surface stabilization and protection structures, relying solely on direct drill bit penetration. This allows vibrations to continuously penetrate deeper into the rock, exacerbating the risk of fracture expansion and rock fragment detachment. Therefore, it is necessary to propose a laser-positioned rock drilling rig-based drilling device for drilling operations. Summary of the Invention

[0003] To address the problems in the prior art, this invention provides a laser-positioned rock drilling rig with a hole-drilling device.

[0004] The technical solution adopted by this invention to solve its technical problem is: a laser-positioned rock drilling rig with a hole-drilling device, including a turntable, a laser emitter installed at the top edge of the turntable, a sliding frame at the top of the turntable, a sliding arm slidably engaged at the inner end of the sliding frame, a stabilizing component at the front end of the sliding arm, the stabilizing component including a mounting block installed at the front end of the sliding arm, an arc-shaped rod 1 longitudinally penetrating on both sides of the mounting block, an arc-shaped rod 2 laterally arranged in the middle of the mounting block, a plate fixedly connected to both ends of the arc-shaped rod 2, a plurality of pins fixedly connected to the outer wall of the plate, an arc-shaped inner groove in both the longitudinal and transverse directions of the inner end of the mounting block, a slider slidably engaged at the inner end of the arc-shaped inner groove, a ball stop between two sliders, and a circulating liquid storage chamber in the inner end of the plate, the liquid storage chamber circulating to the inner end of the pins.

[0005] Specifically, a cylinder is provided between the sliding arm and the sliding frame, and a drilling assembly is provided at the top of the sliding arm. The drilling assembly includes a support frame mounted on the sliding arm. Two cylinders are fixedly connected to the inner wall of the support frame. A sliding frame is fixedly connected to the output end of the cylinders. A drive motor is fixedly connected to the outer wall of the sliding frame, and a drill bit rod is fixedly connected to the output end of the drive motor.

[0006] Specifically, a limiting block is fixedly connected to the bottom of the sliding frame, the limiting block is slidably engaged with a groove opened at the top of the sliding arm, and a laser receiver is installed at the top of the sliding frame.

[0007] Specifically, the second arc-shaped rod is located inside the two first arc-shaped rods.

[0008] Specifically, the contact surfaces of the two sliders and the ball are provided with grooves that match the ball.

[0009] Specifically, a rubber stopper is embedded at the liquid inlet end of the liquid storage chamber.

[0010] Specifically, the two sliders are respectively positioned near the central axis of the arc-shaped inner groove.

[0011] The beneficial effects of this invention are: On the one hand, the design of the stabilizing components effectively solves the problems of rock surface loosening and rock powder falling into the hole caused by drilling vibration. Arc rod one and arc rod two can adaptively deform with the curvature of the rock surface, and together with the sliding and rolling of the slider and the ball, ensure that the plate fits tightly against different uneven rock surfaces; On the other hand, the insertion of the pin into the rock surface achieves initial fixation. The non-Newtonian medium in the liquid storage chamber hardens upon vibration, absorbs vibration energy, and strengthens the rigidity of the pin. After the vibration disappears, it returns to a fluid state, which not only avoids rock powder falling into the hole and affecting the drilling quality, but also protects the rock surface structure and improves the safety of operation. It is especially suitable for drilling scenarios with fractured and fissured rock surfaces. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0016] like Figures 1-6 As shown, the present invention provides the following technical solution: Example 1: A laser-based rock drilling rig includes a turntable 1, a laser emitter 10 mounted on the top edge of the turntable 1, a sliding frame 11 at the top of the turntable 1, a sliding arm 12 slidably engaged at the inner end of the sliding frame 11, a cylinder 110 between the sliding arm 12 and the sliding frame 11, a drilling assembly 2 at the top of the sliding arm 12, the drilling assembly 2 including a support frame 21 mounted on the sliding arm 12, two cylinders 22 fixedly connected to the inner side wall of the support frame 21, a sliding frame 23 fixedly connected to the output end of the cylinders 22, a drive motor 25 fixedly connected to the outer wall of the sliding frame 23, a drill bit rod 26 fixedly connected to the output end of the drive motor 25, a limit block 24 fixedly connected to the bottom end of the sliding frame 23, the limit block 24 slidably engaged with a groove 101 opened at the top of the sliding arm 12, and a laser receiver 20 mounted at the top of the sliding frame 23.

[0017] The cylinder 110, cylinder 22, and drive motor 25 are connected to an external power source via a controller on the vehicle body. In use, the device is moved to the work area, and the laser emitter 10 is activated to project hole positioning marks onto the working rock surface. The laser receiver 20 captures the positioning signal and, in conjunction with cylinder 110, pushes the sliding arm 12 along the sliding frame 11 to adjust its position, aligning the drill rod 26 with the target hole. Cylinder 22 is activated, pushing the sliding frame 23 to slide smoothly along the slide groove 101. The limiting block 24 acts as a guide and limiter, preventing the sliding frame 23 from shifting. After adjustment, the drive motor 25 is activated, rotating the drill rod 26, while cylinder 22 continues to advance, completing the single-hole drilling operation. Repeating the above steps completes the drilling of the entire row of holes.

[0018] Example 2: The technical solution of this example, which differs from Example 1, includes: a stabilizing component 3 is provided at the front end of the sliding arm 12. The stabilizing component 3 includes a mounting block 31 installed at the front end of the sliding arm 12. A first arc-shaped rod 32 is longitudinally arranged through both sides of the mounting block 31. A second arc-shaped rod 33 is laterally arranged in the middle of the mounting block 31. A plate 34 is fixedly connected to both ends of the second arc-shaped rod 33. Several pins 35 are fixedly connected to the outer wall of the plate 34. An arc-shaped inner groove 301 is formed in both the longitudinal and transverse directions at the inner end of the mounting block 31. A slider 330 is slidably engaged at the inner end of the groove 301. A ball stop 331 is provided between the two sliders 330. A liquid storage chamber 302 is provided at the inner end of the plate 34. The liquid storage chamber 302 extends to the inner end of the insert pin 35. The second arc rod 33 is located inside the two first arc rods 32. The contact surfaces of the two sliders 330 and the ball stop 331 are provided with ball grooves that match the ball stop 331. A rubber stopper 36 is embedded at the liquid inlet end of the liquid storage chamber 302. The two sliders 330 are respectively located near the central axis of the arc inner groove 301.

[0019] The slider 330 and the ball 331 work together. The slider 330 slides along the arc-shaped inner groove 301 and the ball 331 rolls. The auxiliary plate 34 adapts to the curvature of the rock surface to further improve the bonding effect. The liquid storage chamber 302 is used to store non-Newtonian media. The rubber stopper 36 is used to seal the liquid storage chamber 302 to prevent media leakage. The ball groove on the slider 330 matches the ball 331 to ensure that the ball 331 rolls smoothly. The two sliders 330 are set close to the central axis of the arc-shaped inner groove 301 to ensure uniform force.

[0020] In use, first remove the rubber stopper 36, inject a suitable non-Newtonian medium into the storage chamber 302 to seal the rubber stopper 36; when adjusting the position of the sliding arm 12, the stabilizing component 3 moves synchronously with the sliding arm 12, pushing the mounting plate 34 to adhere to the working rock surface, and the pin 35 is inserted into the rock surface (without damaging the rock surface) to achieve initial fixation; the arc rod 1 32 and arc rod 2 33 can adaptively deform according to the curvature or unevenness of the rock surface (when one end of arc rod 1 or 2 is pressed by the rock surface, it drives the ball 331 to roll and pulls the other end of arc rod 1 or 2 to slide and adapt, so as to achieve proper adhesion of the mounting plate 34 to different uneven rock surfaces). The slider 330 slides synchronously along the arc-shaped inner groove 301, further assisting the mounting plate 34 to adhere tightly to the rock surface. It can adhere to walls with different concave and convex surfaces. The slider 330 slides along the arc-shaped inner groove 301, and the ball 331 rolls between the two sliders 330 to assist the mounting plate 34 to adhere to the rock surface. When high-frequency vibration is generated during drilling, the non-Newtonian medium in the storage chamber 302 and the needle 35 hardens upon encountering vibration, absorbs vibration energy, strengthens the rigidity of the needle 35, and prevents rock powder from falling into the hole. After the vibration disappears, the medium returns to a fluid state, ensuring the adhesion stability of the mounting plate 34. The rest of the drilling operation is the same as in Example 1.
