Description

Technical Field

[0001] The utility model belongs to the technical field of rock drilling trolleys, and more specifically, particularly relates to a double-bend rock drilling trolley. Background Art

[0002] A rock drilling rig, also known as a drilling rig, is a rock drilling equipment used in tunnel and underground engineering construction using the drill and blast method. It can move and support multiple rock drills to perform drilling operations simultaneously. The working mechanism is mainly composed of a thruster, a drill arm, a rotary mechanism, and a translation mechanism. The rock drilling rig can be divided into a horizontal tunnel excavation drill rig, a mining drill rig, an anchor drill rig, and a rock drilling rig for open-pit mining.
