Description

Technical Field

[0001] The utility model relates to the technical field of blasting engineering, in particular to a self-propelled rock drilling stand which can be raised and lowered. Background Art

[0002] When conducting tunnel excavation and blasting operations, especially when transitioning from a branch tunnel to a main tunnel or underground space, it is necessary to raise and expand the excavation and convert from a small section to a large section. Currently, when conducting tunnel blasting and excavation, the commonly used drilling methods are manual rigs and rock drilling rigs.

[0003] Artificial gantry: It is a metal working platform of fixed size welded with I-beams according to the size of the tunnel excavation section, commonly known as the "gantry", and then the workers stand on the gantry to perform drilling and blasting work; when using this method, due to the fixed size of the gantry, when the cross-sectional position of the tunnel changes, it can only be moved or remade, and the work intensity is relatively high. There are handles at both ends of the rock drill and a chisel head on one side. The workers hold the handles on the gantry and drill the tunnel with the chisel head. Long-term use will cause a certain degree of damage to the body.

[0004] Rock drilling rig: It has a high degree of automation. People can drill holes by operating the mechanical arm. It is suitable for both large and small sections. It has its own power system and can move autonomously.
