[0003] The propulsion beams of narrow and low-profile equipment are basically constructed using wire rope, chain, or a combination of both. This design has significant drawbacks: the propulsion beam is relatively long, the wire ropes are prone to breakage, the chains wear out quickly and are difficult to replace, and the motors driving the chains have a high failure rate. While some propulsion beams use a single hydraulic cylinder, this is difficult to achieve with short chisel structures due to limitations imposed by the cylinder mounting distance.

[0021] The W-shaped slide rail inner groove 33 is made in one piece, and consists of a vertical part and two U-shaped bent parts.

[0022] The lower slider 35 is provided with a rectangular slot, and the U-shaped bend of the inner groove 33 of the W-shaped slide rail engages in the rectangular slot on the side wall of the lower slider 35.

[0023] The upper slider 34 is composed of two parts, upper and lower. The U-shaped part of the inner groove 33 of the W-shaped slide rail is engaged in the upper half of the upper slider 34, and the lower half of the upper slider 34 is engaged in the U-shaped part of the inner groove 33 of the W-shaped slide rail.

[0024] A hydraulic cylinder pin 16 is provided on the side wall of the inner push beam 2. The inner push beam 2 is movably connected to the lower push cylinder 14 through the hydraulic cylinder pin 16. The other end of the lower push cylinder 14 is fixed to the outer push beam 1 through the hydraulic cylinder pin 16. The inner push beam 2 is equipped with an upper push cylinder 15 through the hydraulic cylinder pin 16. The other end of the upper push cylinder 15 is installed on the rock drill mounting base 41 through the hydraulic cylinder pin 16. The front of the rock drill mounting base 41 is provided with a docking seat for connection.

[0025] A hydraulic cylinder pin 16 is provided on the side wall of the inner push beam 2. The inner push beam 2 is movably connected to the lower push cylinder 14 through the hydraulic cylinder pin 16. The other end of the lower push cylinder 14 is fixed to the outer push beam 1 through the hydraulic cylinder pin 16. The inner push beam 2 is equipped with an upper push cylinder 15 through the hydraulic cylinder pin 16. The other end of the upper push cylinder 15 is installed on the rock drill mounting base 41 through the hydraulic cylinder pin 16. The front of the rock drill mounting base 41 is provided with a docking seat for connection.

[0026] A drill bit 12 is fixedly installed on the side wall of the outer push beam 1. A drill bit 12 is installed inside the drill bit 11. A drill rod 13 is fixedly installed on the side wall of the drill bit 12. The drill rod 13 is threadedly connected to the rotating head of the rock drill 3. A sensor 4 is installed on the side wall of the drill bit 11. The sensor 4 is fixed to the outer push beam 1 by bolts. A rectangular seat 51 is fixedly installed on the side wall of the drill bit 11. A positioning hole 52 is provided on the rectangular seat 51.

[0027] The telescopic rods of the rear support cylinder 22 and the front support cylinder 24 extend and press against the top and bottom of the roadway, respectively. Fixed plugs 25 are provided at the ends of the telescopic rods of the rear support cylinder 22 and the front support cylinder 24. The presence of fixed plugs 25 makes the position stability of the equipment against the top and bottom stronger, making the propulsion beam less prone to shaking and improving the stability of the equipment. At the same time, a cylinder fixing clamp 23 is fixedly installed on the side wall of the outer propulsion beam 1. The presence of the cylinder fixing clamp 23 and the cylinder mounting seat 21 fixes the rear support cylinder 22 and the front support cylinder 24, improving the working stability of the rear support cylinder 22 and the front support cylinder 24.

[0028] By activating drill rod 13 and lower thrust cylinder 14, oil is introduced into drill rod 13 and lower thrust cylinder 14. After the drill rod 13 is activated, it pushes the inner thrust beam 2 to slide. The activation of lower thrust cylinder 14 pushes the rock drill mounting base 41 to slide. The front end of the inner thrust beam 2 is guided by the lower slider 35 in the inner groove 33 of the W-shaped slide rail, and the rear end of the inner thrust beam 2 is guided by the upper slider 34 above the inner groove 33 of the W-shaped slide rail. The rock drill mounting base 41 is guided by the upper slider 34 above the inner groove 33 of the W-shaped slide rail. Through the cooperation of these three, the stability of the equipment adjustment is improved.

[0029] When the rock drill 3 slides to the position of sensor 4, it automatically stops. Then, the drill rod 13 is clamped with the chuck 11, and the output shaft of the rock drill 3 is reversed, allowing the drill rod 13 to rotate on the output shaft of the rock drill 3, thus removing the drill rod 13. The drill rod 13 and the lower push cylinder 14 are then moved to retract the rock drill 3, returning it to the rear of the equipment. Another drill rod 13 is then taken to connect to the drill rod. After connecting the rod, the above actions are repeated until the required drilling depth is reached. After drilling is completed, the rock drill 3 is returned, and the drill rod is clamped with the chuck 11 to remove the first drill rod 13. Then, the rock drill 3 is pushed forward and screwed into the second drill rod 13. The chuck 11 is released, and the rock drill 3 begins to return. When it reaches the position of the third drill rod 13, the drill rod 13 is clamped, and the rod removal continues. This action is repeated until the rod removal is completed. The entire process is relatively easy to operate.

[0030] Working principle: Step 1: The telescopic rods of the rear support cylinder 22 and the front support cylinder 24 extend and press against the top and bottom of the roadway, respectively. Fixed plugs 25 are provided at the ends of the telescopic rods of the rear support cylinder 22 and the front support cylinder 24. The presence of fixed plugs 25 makes the position of the equipment against the top and bottom more stable, making the propulsion beam less prone to shaking and improving the stability of the equipment. At the same time, a cylinder fixing clamp 23 is fixedly installed on the side wall of the outer propulsion beam 1. The presence of the cylinder fixing clamp 23 and the cylinder mounting seat 21 fixes the rear support cylinder 22 and the front support cylinder 24, improving the working stability of the rear support cylinder 22 and the front support cylinder 24.

[0031] Step 2: By activating drill rod 13 and lower thrust cylinder 14, oil is introduced into drill rod 13 and lower thrust cylinder 14. After the drill rod 13 is activated, it pushes the inner thrust beam 2 to slide. The activation of lower thrust cylinder 14 pushes the rock drill mounting base 41 to slide. The front end of the inner thrust beam 2 is guided by the lower slider 35 in the inner groove 33 of the W-shaped slide rail, and the rear end of the inner thrust beam 2 is guided by the upper slider 34 above the inner groove 33 of the W-shaped slide rail. The rock drill mounting base 41 is guided by the upper slider 34 above the inner groove 33 of the W-shaped slide rail. Through the cooperation of these three, the stability of the equipment adjustment is improved.

[0032] Step 3: When the rock drill 3 slides to the position of sensor 4, it automatically stops. Then, the drill rod 13 is clamped with the chuck 11, and the output shaft of the rock drill 3 is reversed to allow the drill rod 13 to rotate on the output shaft of the rock drill 3, thereby removing the drill rod 13. The drill rod 13 and the lowering cylinder 14 are then moved to retract the rock drill 3 back to the rear of the equipment. Another drill rod 13 is then taken to connect to the drill rod. After connecting the rod, the above actions are repeated until the required drilling depth is reached. After drilling is completed, the rock drill 3 is returned, and the drill rod is clamped with the chuck 11 to remove the first drill rod 13. Then, the rock drill 3 is pushed forward and screwed into the second drill rod 13. The chuck 11 is released, and the rock drill 3 begins to return. When it reaches the position of the third drill rod 13, the drill rod 13 is clamped, and the rod removal continues. This action is repeated until the rod removal is completed. The entire process is relatively easy to operate.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
