Description

Technical Field

[0001] This utility model relates to the manufacturing and application of coal mine roadway support equipment and blast hole construction equipment, and in particular to an integrated rock roadway drilling and anchoring machine. Background Technology

[0002] Currently, coal mine roadway excavation technology has not yet fully achieved mechanization and automation, especially in the construction of blast holes and anchor bolt / cable support in rock roadways. Most of these processes still rely on traditional handheld drilling rigs. This not only affects the quality of anchor bolt support and blast hole construction, such as the accuracy of drilling direction, depth, and diameter, as well as the quality of anchor bolt installation and blasting, but also presents problems such as poor operator safety, high labor intensity, poor working conditions, and low support efficiency.

[0003] Besides manual construction, existing rock tunnel excavation methods include two other approaches. One involves using a TBM (Tunnel Boring Machine), which integrates two or more onboard rock bolting rigs into one unit, enabling a single machine to perform both hard rock excavation and rock bolt / anchor cable support. However, this equipment has disadvantages such as high price, large size, heavy weight, and long installation time, making it unsuitable for short-distance tunnel excavation and resulting in low cost-effectiveness. The other approach uses a combination of two types of equipment: a rock drilling rig for drilling blast holes and a rock bolting rig for rock bolt / anchor cable support. This method involves dispersed processes and frequent equipment switching, leading to long operation times and low efficiency. Furthermore, the coordination of multiple machines in narrow tunnels is more difficult due to the influence of other equipment at the working face, requiring more space and presenting challenges such as difficulty in equipment entry, exit, and passing, further slowing down the construction progress.

[0004] In view of the above, it is necessary to develop a multifunctional rock tunnel drilling and anchoring integrated machine to solve the existing problems in rock tunnel excavation and support, and achieve a comprehensive improvement in safety, efficiency, sustainability and quality standardization. Utility Model Content

The traveling part 12 is connected to the lower part of the main body 15 to drive the drilling and anchoring machine to move back and forth. The four-bar linkage 16 and swing arm mechanism 17 are connected to the upper front center of the main body 15, working together to lift the working platform 18. The working platform 18 is also connected to the upper front center of the main body 15 via a hydraulic cylinder pin, allowing it to be lifted 1000mm under the action of the hydraulic cylinder. The front support mechanism 2, drill arm mechanism 3, and drill arm operating table mechanism 5 are all connected to the working platform 18. Two drill arm mechanisms 3 are symmetrically arranged on both sides of the front support mechanism 2. The drill arm operating table mechanism 5 is mounted on the working platform 18 and does not move with the drill arm mechanism 3, ensuring convenience, stability, and operator safety. The drilling mechanism 1 is located at the free end of the drill arm mechanism 3 and can swing at any angle within the front hemisphere of the drill-anchor integrated machine. The support base group 6 is connected to the upper middle part of the main body 15, and the oil tank part 10, the cover plate part 13, the motor oil pump part 14, and the rear support mechanism 11 are connected to the rear of the main body 15.

[0047] Specifically, refer to Figure 2 As shown, the drilling mechanism 1 mainly includes: a rock drill 1-1, a slide assembly 1-2, a frame assembly 1-3, and a sliding base 1-4. The rock drill 1-1 is movably mounted on the upper part of the slide assembly 1-2, and slides on the slide assembly 1-2 via a primary hydraulic cylinder and a chain assembly. The slide assembly 1-2 is movably mounted on the upper part of the frame assembly 1-3, and slides on the frame assembly 1-3 via a secondary hydraulic cylinder, enabling the drilling mechanism to complete a two-stage propulsion. The bottom of the sliding base 1-4 is used to movably connect with the drill arm mechanism 3. The side of the frame assembly 1-3 is provided with a connecting seat 1-5, and the lower part of the connecting seat 1-5 is slidably connected to the side of the sliding base 1-4. The frame assembly 1-3 slides along the sliding base 1-4 under the action of the sliding hydraulic cylinder 1-6 to increase the stroke of the propulsion mechanism and facilitate drilling blast holes. The rock drill 1-1 also includes a clamping mechanism 1-7 and a drill bit holder assembly 1-8. The lower part of the clamping mechanism 1-7 is fixedly connected to the end of the frame assembly 1-3 via a telescopic hydraulic cylinder, and the drill bit holder assembly 1-8 is fixedly connected to the end of the slide assembly 1-2.

[0048] The rock drill 1-1 is an existing impact rock drill with a drill tail adapter sleeve, which can meet the construction operations of drilling blast holes and installing anchor bolts on the same machine. The bottom of the rock drill 1-1 is also equipped with a wear-resistant plate for direct contact with the upper part of the slide assembly 1-2, ensuring smoothness and wear resistance during the rock drill's advance. The drill bit holder assembly 1-8 uses double drill bit holders. These double drill bit holders, together with the clamping mechanism, enable the rock drill to maintain high accuracy and stability during operation, reducing sway and increasing efficiency.

[0049] Reference Figure 3 As shown, the front support mechanism 2 includes: a support top plate assembly 2-1, a support leveling assembly 2-2, a support telescopic assembly 2-3, and a front-to-back telescopic assembly 2-4. The cylinder base of the front-to-back telescopic assembly 2-4 is bolted to the bottom of the working platform 18. The moving end of the cylinder of the front-to-back telescopic assembly 2-4 is mounted to the outer sleeve of the support telescopic assembly 2-3 via a pin and a baffle. The extension and retraction of the cylinder of the front-to-back telescopic assembly 2-4 can drive the support telescopic assembly 2-3 to rotate back and forth around the pin at the connection between the working platform 18 and the support telescopic assembly 2-3. The lower middle part of the outer sleeve of the support telescopic assembly 2-3 is mounted to the front middle of the working platform 18 via a pin and a baffle. The inner sleeve of the support telescopic assembly 2-3 is connected to the bottom of the support leveling assembly 2-2 via a pin, used to drive the support leveling assembly 2-2 and the support top plate assembly 2-1 to adjust up and down. The support leveling assembly 2-2 includes two adjusting ears 2-2-1 extending downwards from the middle top plate of the support top plate assembly 2-1. An adjusting cylinder 2-2-2 is movably connected between the two adjusting ears 2-2-1, allowing for angle adjustment of the support top plate assembly 2-1 by extending and retracting the adjusting cylinder 2-2-2. The support top plate assembly 2-1 includes a middle top plate 2-1-1 and side top plates 2-1-2 hinged to both sides. A telescopic cylinder is provided between the side top plates 2-1-2 and the middle top plate 2-1-1 for extending and retracting the side top plates 2-1-2. Thus, the support top plate assembly 2-1 can retract when the drilling rig is moving, maintaining the stability of the drilling rig, and unfold into an arch shape during drilling operations for temporary support of the open roof. The front support mechanism 2 also has the function of lifting heavy objects (such as: roof mesh, W-shaped steel strips, I-beams, etc.), greatly reducing the labor intensity of workers.

One end of the drill arm rotation assembly 3-1 is movably connected to the working platform 18 via a pin and a baffle, and the other end is movably connected to the outer sleeve of the drill arm telescopic assembly 3-3 and the fixed end of the telescopic cylinder of the drill arm support assembly 3-2 via a rotary seat. When the rotary cylinder of the drill arm rotation assembly 3-1 extends, it drives the rotary seat to rotate outward, and when the cylinder retracts, it drives the rotary seat back to its original position. The outer sleeve of the drill arm telescopic assembly 3-3 is installed on the rotary seat of the drill arm rotation assembly 3-1 via a pin and a baffle. The fixed end of the inner telescopic cylinder of the drill arm telescopic assembly 3-3 is connected to the outer sleeve of the drill arm telescopic assembly 3-3 via a pin, and the moving end of the telescopic cylinder is connected to the drill arm via a pin. The inner sleeve of the telescopic assembly 3-3 extends and retracts via a hydraulic cylinder. The fixed end of the hydraulic cylinder of the drill arm support assembly 3-2 is connected to the rotary seat of the drill arm rotation assembly 3-1 via a pin, and the moving end is connected to the bottom of the outer sleeve of the drill arm telescopic assembly 3-3 via a pin. When the hydraulic cylinder of the drill arm support assembly 3-2 extends, it lifts the drill arm telescopic assembly 3-3 upward; when the hydraulic cylinder of the drill arm support assembly 3-2 retracts, it retracts the drill arm telescopic assembly 3-3 back to its original position. The drill arm leveling assembly 3-5 is connected to the top of the inner sleeve of the drill arm telescopic assembly 3-3 via a pin. The extension of the inner telescopic hydraulic cylinder of the drill arm leveling assembly 3-5 adjusts the angle of the arm rotation assembly 3-6. The boom slewing assembly 3-6 is connected to the drill arm leveling assembly 3-5 via a pin. The boom slewing assembly 3-6 also includes two axially vertical swing cylinders. The first swing cylinder is rotatably connected to the sliding base 1-4 of the drilling mechanism 1.

The support base 6-2 is bolted to the upper part of the main body 15; the air tank assembly 6-1 is bolted to the upper part of the support base 6-2. The air tank assembly 6-1 is used to store the compressed air from the air compressor unit 13-1 and plays a role in stabilizing the air pressure.

[0053] Refer to Figure 4 As shown, the drill arm leveling assembly 3-5 of the drill arm mechanism 3 in this embodiment is also equipped with a pneumatic triplet 3-4. Thus, the air compressor unit 13-1, the air tank assembly 6-1, and the pneumatic triplet 3-4, connected sequentially through pipelines, form an aerosol lubrication mechanism that provides lubricating oil mist to the rock drill 1-1, thereby improving the working efficiency of the rock drill 1-1 and extending its service life. Specifically, the air compressor unit 13-1 compresses air to 0.8 MPa and stores it in the air tank assembly 6-1. The pneumatic triplet 3-4 first filters the compressed air in the air tank assembly 6-1 to remove moisture, then reduces its pressure to 0.1 MPa. The filtered air then carries oil mist through an oil injector into the rock drill 1-1, lubricating the drill bit, and also providing heat dissipation, dust prevention, preventing rock cuttings from entering the rock drill, and sealing the rock drill, thereby extending its service life.

[0054] Reference Figure 7 As shown, the rear support mechanism 11 includes a connecting frame 11-1, a telescopic cylinder assembly 11-2, and a support leg 11-3.

This integrated drilling and anchoring machine obtains power from the hydraulic pump and then transmits the power to each actuator through the hydraulic lines, cooperating with the corresponding control valves of each actuator to complete drilling and other actions.

[0057] In this embodiment, the integrated drilling and anchoring machine for rock tunnels, when retracted, has dimensions of 7000mm in length, 1400mm in width, and 2600mm in height, making it suitable for operation inside tunnels with a width of 6000mm and a height of 4700mm. When the drilling rig reaches the working position for construction, workers work on both sides of the working platform 18. During operation, the telescopic cylinders and their operating valves at the drill arm mechanism 3 and the front support mechanism 2 allow the front support mechanism 2 to provide timely support against the roof, eliminating the need for roof-mounted work. The drill arm mechanism 3 can be adjusted up and down, left and right, and extended and retracted forward and backward, allowing the drilling mechanism 1 to reach the drilling position. Then, under the control of the electrical system 9 and the hydraulic system 7, the drilling operation is completed.

[0058] This embodiment of the integrated rock drilling and anchoring machine features a rational overall structure, high-strength and rigid components, a compact design, full hydraulic control, and a high degree of mechanization. Its crawler-type movement utilizes a reliable hydraulic-mechanical transmission, resulting in a small turning radius and flexible maneuverability. Two drill arms provide simultaneous roof and sidewall support, improving support efficiency. The machine employs operator access from both sides of the working platform and a retractable arched front support mechanism, ensuring good safety, reducing worker fatigue, improving the working environment, and adapting to harsh conditions. It is an ideal safety device for underground coal mining. This integrated rock drilling and anchoring machine can achieve the goals of safe, efficient, and mechanized operations in my country's coal mining industry, enriching the variety of anchor drilling rigs suitable for coal mine roadways in my country.

[0059] This utility model of a rock tunnel drilling and anchoring integrated machine enables drilling and anchoring to be completed in one step, without the need to switch equipment, thus improving efficiency. In essence, it is a concentrated embodiment of the coal mining industry's demand for efficient, safe, and low-cost construction, solving problems such as high labor intensity for workers, low support efficiency, poor safety, and frequent misalignment. It meets the operational requirements of different work tasks and working conditions, and effectively solves problems in tunnel support and other auxiliary operations.
