Description

Technical Field

[0001] The present invention belongs to the technical field of drilling equipment, and particularly relates to a drilling device for high-steep slopes. Background Art

[0002] Down-the-hole drills are commonly used drilling equipment in civil engineering construction. Many existing drilling equipment can only operate in relatively flat or low areas. On these complex terrains, the stability and operability of the equipment will be greatly affected, and even normal construction cannot be carried out, which limits the application of the vegetation hole construction technology under different terrain conditions.

[0003] For existing non-self-propelled or poorly mobile drilling equipment, it is rather difficult to transfer between high-steep slope construction areas. External hoisting equipment or a large amount of manpower is required for handling and repositioning, which greatly increases the non-operation time during the construction process and reduces the construction efficiency. It has insufficient adaptability to complex terrains such as mountains, steep slopes, and rugged terrains.

[0004] In the prior art, a self-propelled slope drilling trolley disclosed in a Chinese patent (CN222066637U), which belongs to the technical field of civil engineering construction, includes a traveling mechanism. The traveling mechanism is formed by connecting and fixing several steel pipes through cross fasteners. A winch and a steel wire rope arranged on the winch are provided at the bottom of the traveling mechanism. An anti-disengagement hook is provided at the end of the steel wire rope. The winch is driven to rotate by a variable-speed motor. The anti-disengagement hook at the end of the steel wire rope is connected to an anchor bar at the top of the slope. A drill rig holding frame is welded on the side wall of the traveling mechanism, and a down-the-hole drill is connected to the drill rig holding frame; This method has the following defects: When arranging the drilling trolley to a fixed construction position for drilling operations, the construction worker needs to be lowered to the construction position in advance, set up a mechanical fixed anchor bar at the top of the slope, connect the anti-disengagement hook of the steel wire rope to the fixed anchor, and use the winch to lower the drilling trolley to the drilling position. During the drilling process, due to the vibration generated by the down-the-hole drill, it is easy for the trolley to be affected by the vibration and shake. The shaking of the trolley will cause the drill rig to shake during the drilling process, resulting in the drill pipe shaking during the downward drilling process, reducing the drilling efficiency and affecting the drilling effect; and when drilling operations are carried out on the surface of a rock slope, generally, concrete-cast anchor bolts need to be set at the top of the slope. The fixed anchor bolts are used to fix the anti-disengagement hook. During the process of lowering the equipment with the anti-disengagement hook, the hook will be displaced due to vibration, and the steel wire rope directly contacts the rock surface, which is prone to wear and reduces the service life.

[0005] In the prior art, a device for drilling in rocky high slopes disclosed in a Chinese patent (CN117846489A) includes: a chassis, a first winch, a second winch, a down-the-hole drill, and a first electric push rod. There are two first winches, and the two first winches are respectively fixedly installed on the front and rear sides of the upper end of the chassis. This device is connected to an electric hoist through a steel wire rope, facilitating vertical movement. During the movement, four rollers can respectively perform telescopic movement on one side of the chassis, making it easy for the device to stably pass through uneven places when crawling on the slope. On one side of the bracket, a slide bar is slidably connected through a third electric push rod. On the upper end of the slide bar, a fixed box is slidably connected through a second electric push rod. The upper end of the fixed box is slidably connected to an installation platform, and the down-the-hole drill is fixedly installed on the upper end of the installation platform, changing the lateral position of the down-the-hole drill to drill holes at different lateral positions of the slope body and improving the drilling efficiency; This method has the following defects: When adjusting the angle of the drill on the surface of the rock slope, the surface of the rock is complex. The chassis falling on the rock surface causes the angle of the drill to be adjusted from various angles in three-dimensional space. This device can only be adjusted in the lateral direction of the drill, making it difficult to ensure the accuracy of drilling.

[0006] In summary, the prior art has the following defects: First, during the drilling process, due to the vibration generated by the down-the-hole drill, it is easy for the trolley to be affected by the vibration and shake. The shaking of the trolley will cause the drill to shake during the drilling process, causing the drill pipe to shake during the downward drilling process, reducing the drilling efficiency and affecting the drilling effect; Second, during the process of lowering the equipment by the anti-disengagement hook, the hook will be displaced due to vibration, and the steel wire rope directly contacts the rock surface, easily causing wear and reducing the service life; Third, the chassis falling on the rock surface causes the angle of the drill to be adjusted from various angles in three-dimensional space. This device can only be adjusted in the lateral direction of the drill, making it difficult to ensure the accuracy of drilling.

[0007] Therefore, this article provides a high-steep slope drilling device. Summary of the Invention

[0022] In this embodiment, the following problems exist in the prior art: The inventor found the following defects in the prior art: First, during the drilling process, due to the vibration generated by the down-the-hole drill rig, it is easy for the trolley to be affected by the vibration and shake. The shaking of the trolley will cause the drill rig to shake during the drilling process, resulting in the drill pipe shaking during the downward drilling process, reducing the drilling efficiency and affecting the drilling effect; Second, during the process of lowering the equipment by the anti-disconnection hook, the hook will be displaced due to vibration, and the steel wire rope directly contacts the rock surface, which is easy to cause wear and reduce the service life; Third, the chassis lands on the rock surface, resulting in the need to adjust the angle of the drill rig from various angles in the three-dimensional space. This device can only be adjusted in the lateral direction of the drill rig, making it difficult to ensure the drilling accuracy of the drill rig. Embodiment 1

After that, the fixed bracket is removed, the fixed bracket is set at the fixed point, the bracket fixing anchor rod 10 is taken out, and the bracket fixing anchor rod 10 is driven into the ground. After grouting and pouring for fixation, the fixed bracket is passed through the bracket fixing anchor rod 10 and fixed; After setting the operation anchor rod for the construction worker on the slope top, the construction worker descends to the position where drilling is required using a safety rope, drills a positioning hole at the drilling point using a hand drill, puts the drilling fixing anchor 9 into the positioning hole, and then the construction worker moves to a safe position; After that, the construction worker on the slope top buckles the front end of the hoist a6 to the upper end of the fixed bracket using a safety buckle, and controls the hoist a6 through the control cabinet 5 to lower the device from the slope top to the drilling point. The construction worker on the slope surface connects the base fixing anchor 8 and the drilling fixing anchor 9 to fix the device; After fixing the mobile base 1, the construction worker controls the drilling adjustment bracket and the fixed bracket through the control cabinet 5 to adjust the angle of the hydraulic down-the-hole drill 2, so that the drill can drive the drill pipe from the correct position. During the drilling process, the down-the-hole drill rig unit 3 and the compressed air unit provide power and compressed air for the drill, drive the drill pipe into the slope surface, and blow out the dust and slag to complete the drilling work; After completing the drilling work on the vertical slope surface, when the device needs to be moved left and right, the device is retracted upward to the slope top. Then, the fixing of the fixed bracket by the bracket fixing anchor rod 10 is released, the fixed bracket is removed, transferred and fixed to another fixed point, and the fixed bracket is fixed in the same way, and the construction is carried out again in the same steps.

At the same time, the driving motor 19 drives the gear a 20 to rotate, causing the gear b 21 to rotate. The rotation of the gear b 21 causes the moving sliding cylinder 22 to drive the connecting sliding cylinder 18 to move on the fixed rod 16, so as to adjust the position of the connecting sliding cylinder 18, so that the angle of the mounting seat a 14 on the hydraulic rod can change.
