Description

Technical Field

[0001] This utility model belongs to the field of road engineering machinery, and specifically relates to a slope drilling rig. Background Technology

[0002] When drilling on slopes, traditional methods involve manually holding a pneumatic drill or using a drill frame to drill holes. These methods have poor stability and safety. Furthermore, the drill frame is usually a fixed structure, which is complex and heavy, and it is inconvenient to adjust the angle, orientation, and flexibility.

[0003] Patent document with application number "CN201921347801X" discloses a mobile drilling device for slope protection, which consists of a frame, a drilling rig, and wheels. The frame, rear frame, and adjustment frame form a triangular frame structure with wheels. Sliding tubes are fitted onto the longitudinal side rods of the adjustment frame, and butterfly bolts are screwed onto the lower ends of the sliding tubes to fix them at any position on the rods. The drilling rig frame is located on the frame at the front end of the adjustment frame, and the front end of the drilling rig frame is axially connected to the front end of the frame. The lower end of the drilling rig is fixed to the middle of the upper end face of the moving drilling frame. A winch driven by a motor is located at the front end of the frame. One end of a wire rope is fixed to the winch's coil, and the other end of the wire rope has a steel hook that is hooked to an anchor pile located at the top of the slope. Although this prior art has advantages such as simple structure and good stability, and can replace manual labor, the drilling rig angle and orientation cannot be adjusted during use, resulting in poor flexibility.

[0016] Compared with existing technologies, this utility model has the following beneficial effects:

[0017] 1. The slope drilling rig of this utility model has two symmetrically arranged reels. The reels suspend the frame through steel cables and locking sleeves. By adjusting the length of the two steel cables, the attitude of the frame can be adjusted. The mounting frame can be driven by the first hydraulic cylinder to swing the angle, thereby facilitating the adjustment of the drilling angle of the drilling unit and giving the device high construction flexibility.

[0018] 2. The first and second horizontal tubes in this utility model can not only install wheels, but also serve as pivots at the ends of the mounting frame, the first hydraulic cylinder, and the diagonal brace, making the overall structure of the device more compact.

[0019] 3. The diagonal brace in this utility model not only plays a role in assisting support and improving the overall strength, but also can install a limiting ring. The limiting ring can restrict the movement of the sleeve. When the drilling rig vibrates, it can protect the first hydraulic cylinder in the extended state from being affected. Furthermore, the baffle on the limiting ring can not only increase the contact area between it and the sleeve, but also improve the overall structural strength of the limiting ring and the ear plate.

[0020] 4. The guide cylinder in this utility model can play the role of positioning and guiding the steel cable. The rounded corners at the end of the inner hole can prevent the steel cable from being damaged by friction during the extension and contraction process. The guide cylinder can be easily disassembled through the cover plate and can be replaced in time when it is severely worn. The two ends of the guide cylinder are provided with flanges, which can limit the axial movement of the guide cylinder and increase the coverage of the rounded corners, thereby further improving its protective effect on the steel cable.

The drilling unit 300 is installed on the mounting frame 110, and two cable reels 400 are installed on the base frame 120. The two cable reels 400 are symmetrically arranged on both sides of the drilling unit 300. The cable reel 400 is provided with a retractable steel cable 410. The end of the steel cable 410 extends outward from the front end of the frame 100 and is provided with a locking sleeve 420. The locking sleeve 420 is formed by the end of the steel cable 410 itself being bent into a ring shape. A buckle is installed at the end of the steel cable 410, and the buckle can be engaged with the middle of the steel cable 410.

[0040] More specifically, the drilling unit 300 includes a guide rail 310, a slide block 320, a guide rod 330, a first end plate 340, a second end plate 350, a pneumatic drill assembly 360, and a second hydraulic cylinder 370. There are two guide rails 310, which are fixedly connected to the mounting bracket 110. The first end plate 340 is fixedly connected to the top of the guide rail 310. The second hydraulic cylinder 370 is fixedly installed between the two guide rails 310. The telescopic rod of the second hydraulic cylinder 370 passes through the first end plate 340 and is fixedly connected to the second end plate 350. The slide block 320 is slidably installed on the guide rail 310. The pneumatic drill assembly 360 is fixedly connected to the slide block 320.

The side of the limiting ring 540 is provided with an opening 541. On both sides of the opening 541, there is an outwardly extending ear plate 542. The two ear plates 542 are connected by locking bolts 543 and nuts 544. A baffle 545 is provided at the end of the limiting ring 540 facing the sleeve 520. The baffle 545 is fixedly connected to both the limiting ring 540 and the ear plate 542. The baffle 545 can abut against the end face of the sleeve 520.

[0042] In addition, two mounting seats 610 are provided on the first horizontal tube 121. The position of the mounting seats 610 corresponds to the position of the cable reel 400. A detachable cover plate 620 is provided on the mounting seat 610. The cover plate 620 is connected to the mounting seat 610 by bolts. The guide cylinder 600 is detachably installed between the mounting seat 610 and the cover plate 620. Outwardly folded flanges 603 are provided at both ends of the guide cylinder 600. An inner hole 601 is provided through both ends of the guide cylinder 600. The axis of the inner hole 601 points to the front end of the frame 100. The steel cable 410 can pass through the inner hole 601. The edges of both ends of the inner hole 601 are provided with rounded corners 602.

[0043] Next, the working principle of a slope drilling rig in this embodiment will be described in detail to enable those skilled in the art to better understand this utility model:

[0044] In use, first, the locking sleeve 420 at the end of the steel cable 410 is placed on a fixed object located at the top of the slope. The fixed object can be a tree, a man-made fixed object, or a heavy object. Then, the two reels 400 are slowly and synchronously released, allowing the steel cable 410 to be extended and the frame 100 to slowly descend along the slope. After the frame 100 descends to the designated position, the drilling position may be offset due to the possible difference in height between the wheels 200 on both sides of the frame 100 and the error in the fixed position. Therefore, the length of the two steel cables 410 can be finely adjusted to adjust the posture and deflection angle of the frame 100. Then, the extension length of the first hydraulic cylinder 130 is adjusted, so the angle between the mounting frame 110 and the base frame 120 can be adjusted as needed, thereby adjusting the drilling angle of the drill bit of the pneumatic drill assembly 360. After adjustment, the locking bolt 543 on the locking limit ring 540 is tightened to securely limit the sleeve 520.

[0045] In summary, the slope drilling rig in this embodiment has two symmetrically arranged reels 400 on the frame 100. The reels 400 suspend the frame 100 through steel cables 410 and locking sleeves 420. By adjusting the length of the two steel cables 410, the attitude of the frame 100 can be adjusted. The mounting frame 110 can be driven by the first hydraulic cylinder 130 to swing, thereby facilitating the adjustment of the drilling angle of the drilling unit 300 and giving the device high construction flexibility.
