Description

Technical Field

[0001] The invention relates to the technical field of coal mine drilling machines, and in particular to a compact split automatic drilling vehicle with a sinking drill rod frame. Background Art

[0002] China's industrialized coal production process has now entered an era of safe and efficient mining. Coal mines are reasonable spaces dug by humans when digging geological layers rich in coal. They usually include tunnels, shafts, and mining faces. When drilling holes in coal mines, a drilling vehicle device is used. The drill rod drill bit on the drilling vehicle device rotates through power output and drills holes in the coal mine. As the demand for drilling in coal mines increases, the number of meters required for continuous drilling increases, and more and more drill rods need to be installed accordingly. Equipping a large number of drill rods not only makes the load of the drill rig heavier, but also makes the drill rod frame of the drill rig larger, making the drill rig body large, heavy and lengthy, which is not conducive to the flexible application of the drill rig in narrow and long mine tunnels.

[0003] my country's coal resources are unevenly distributed and vary greatly from region to region, so the scale of coal production varies. The self-propelled drilling vehicle has all its functional parts integrated into one, which makes the size of the whole machine too large, and some coal mines cannot use it at all. Therefore, split drilling vehicles are currently used. In addition, the original small and medium-sized coal mines have low automation and unmanned drilling rigs, and there is currently a great market demand for automatic drilling vehicles. However, due to the limited space in the lanes of small and medium-sized coal mines, the requirements for automatic drilling vehicles are not only automation and high unmanned, but also reduce staffing and labor intensity of workers. In terms of appearance and size, they must also be compact and small in size, and can be easily transported to the operating area, and can complete the operation freely in the limited lane space.

[0004] However, the existing split drilling vehicles are still not compact enough, with a height of about 1.87 meters and a slide extension length of about 4.7 meters. For small-scale production mines, the tunnel cross-section is relatively small, and the required equipment dimensions are relatively small. The existing split drilling vehicles are still too large and need to be disassembled and transported to the mine for reassembly, which is time-consuming, labor-intensive and has low stability. Therefore, for complex equipment, effectively controlling its volume is a prerequisite for the smooth lowering and underground transportation of the equipment.

[0005] In summary, the compactness of split drilling rigs is the current research direction of the industry, and achieving continuous and efficient production in small-scale mines is a technical problem that the industry urgently needs to solve. Summary of the invention

[0041] Working principle: In order to meet the market demand of small and medium-sized coal mines, this embodiment provides a split automatic drilling vehicle suitable for small and medium-sized coal mines, which adopts a split structure to separate the working mechanism from the power (including hydraulic system and pump station) mechanism. This split structure can not only shorten the length of the whole machine, but also make the structure more compact and reduce the size because the working mechanism removes the power and hydraulic parts.

[0043] In addition to the split structure, in order to reduce the size of the machine body and to make the height of the main machine lower than 1500mm, the original drill rod box adopts a sunken structure, so that the bottom of the original drill rod box "sinks" into the inside of the main machine frame, thereby reducing the overall height; the slide structure of the working mechanism is also optimized, so that the slide is shortened to the greatest extent without reducing the operating angle range of the working mechanism.

[0044] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the present invention.
