Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to a working platform for constructing long anchor cable holes in underground mines. Background Technology

[0002] As the Jinchuan Mine expands its production and construction to depths below 1,000 meters, long anchor cables are widely used as an effective reinforcement method in high-pressure and fractured rock strata support. The fractured chambers in the mining area are generally characterized by thin upper and lower rock strata, well-developed rock joints, and large chamber spans, resulting in long service lives. Therefore, according to the construction design requirements of the fractured chambers, long anchor cable construction is necessary for the entire fractured chamber. However, due to the generally large cross-section of the fractured chambers, frequent movement of the down-the-hole drill rig is difficult and time-consuming when constructing long anchor cables across the entire cross-section, severely impacting construction efficiency. Utility Model Content

[0003] This utility model provides a working platform for constructing long anchor cable holes in underground mines, in order to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A working platform for constructing long anchor cable holes in underground mines includes parallel guide rails, with channel steel bases adjustablely connected to the guide rails. The top of the channel steel bases is vertically and symmetrically provided with telescopic outer cylinders, and the top of the telescopic outer cylinders is movably connected with pads.

[0005] Furthermore, multiple first U-shaped clips are slidably connected to the guide rail, and each of the first U-shaped clips is detachably connected to the channel steel base.

[0006] Furthermore, each telescopic outer cylinder is movably fitted with a telescopic inner rod, and a horizontal bar is fixedly connected to the top of the telescopic inner rod. Multiple second U-shaped clips are movably connected to the horizontal bar, and each second U-shaped clip is detachably connected to the pad plate.

[0007] Furthermore, multiple adjustment holes are provided on the side walls of both the telescopic outer cylinder and the telescopic inner rod.

[0008] Furthermore, reinforcing ribs are provided between the telescopic outer cylinder and the channel steel base.

[0009] Furthermore, the outer diameter of the telescopic inner rod is smaller than the inner diameter of the telescopic outer cylinder, and the telescopic inner rod and the telescopic outer cylinder are connected by a pin.

[0010] This utility model has the following beneficial effects: This utility model provides a working platform for constructing long anchor cable holes in underground mines, including guide rails, a base, an inner extension rod, and an adjusting bracket. The base consists of a channel steel base and a telescopic outer cylinder. The telescopic mechanism consists of a telescopic inner rod and a crossbar. The adjusting bracket consists of a pad and a U-shaped clamp. The guide rails enable horizontal movement of the down-the-hole drill rig. By adjusting the height of the telescopic outer cylinder and the inner extension rod, and matching the displacement and rotation of the pad, the height and angle of the down-the-hole drill rig can be adjusted, thus enabling efficient construction of long anchor cable holes. This platform has a simple and detachable structure, allows for lateral movement, and its height and angle are adjustable, making the construction of long anchor cable holes more convenient. It effectively reduces the labor intensity of construction personnel, ensures construction safety, and improves overall construction efficiency. It effectively solves the problem that the movement and adjustment process of the down-the-hole drill rig is time-consuming, labor-intensive, and has low precision in current long anchor cable hole construction in underground mines.

According to the anchor cable hole positions marked in the early stage, the first U-shaped clip 10 is used to install the channel steel base 3 on the guide rail 1. Then, the telescopic inner rod 5 is inserted into the telescopic outer cylinder 4. After adjusting the height, the position of the telescopic inner rod 5 is fixed by passing a pin through the adjustment hole 11 on the telescopic outer cylinder 4. Then, the second U-shaped clip 9 is used to install the pad 7 on the crossbar 6. Finally, the down-the-hole drill is installed on the pad 7. After the anchor cable holes in the current row are completed, loosen the fastening nut 8 of the first U-shaped clip 10 on the channel steel base 3 appropriately, move the entire working platform laterally to the next row of construction positions, tighten the fastening nut 8 after determining the position, then pull out the pin on the telescopic outer cylinder 4, adjust the height of the down-the-hole drill, insert the pin into the adjustment hole 11 on the telescopic outer cylinder 4, and then fix the telescopic inner rod 5 securely. Finally, loosen the fastening nut 8 of the second U-shaped clip 9 on the pad 7 appropriately, adjust the angle of the down-the-hole drill, tighten the fastening nut 8, and after fixing it securely, continue the drilling construction in a cycle, and so on until the anchor cable holes in the entire chamber are completed.
