Description

Technical Field

[0001] The utility model relates to the technical field of mine rock drilling, and more particularly to a mine rock drilling device. Background Art

[0002] A mining rock drilling device is a device used to drill holes in order to blast rocks during the mining process. However, the mining rock drilling devices in the existing technology generally adopt a fixed structure design and lack a flexible angle adjustment mechanism. This design leads to obvious limitations of the equipment when performing drilling operations at different angles, and it is impossible to flexibly adjust the drilling angle according to actual geological conditions and construction requirements. In the actual construction process, due to the complex and changeable geological conditions of the mine, different areas may require different drilling angles. The fixed structure is difficult to meet such diverse construction needs, which not only reduces construction efficiency, but may also affect the drilling quality. It may even be impossible to complete the drilling operation under certain special terrain conditions, which seriously restricts the application range and construction effect of the equipment. At the same time, since it cannot be adjusted to the optimal drilling angle, it often causes uneven force on the drill bit, accelerates drill bit wear, increases equipment maintenance costs, and reduces construction efficiency.

[0003] The current technology has obvious deficiencies in the design of the drill pipe installation and disassembly mechanism. The operation process is cumbersome and complicated, and requires the use of multiple professional tools for disassembly and assembly. There are many operation steps and it takes a long time. This inefficient replacement method directly affects the construction progress, increases labor intensity and labor costs, and the cumbersome disassembly and assembly process seriously affects work efficiency. At the same time, the complex operation steps also increase safety hazards, which can easily cause operational errors and personal injuries, affecting construction safety. This situation is more prominent in harsh construction environments, seriously affecting the equipment's utilization efficiency and construction progress.

[0004] In the existing technology, although some equipment adopts some quick disassembly and assembly structures to improve the efficiency of drill rod replacement, its structural design is too simple and there are serious safety hazards. The structural strength is insufficient, resulting in loosening and shaking of the connection parts during high-intensity and long-term drilling operations. In severe cases, there is even a dangerous situation where the drill rod falls off. This instability not only affects the drilling accuracy and efficiency, but also aggravates equipment wear, shortens its service life, and increases maintenance costs. What is more serious is that loosening or falling of the drill rod may cause equipment damage and safety accidents, posing a major safety hazard to construction and causing economic losses. In a working environment with continuous vibration and impact, this structural defect is more likely to cause chain failures, affecting the entire construction process. Utility Model Content
