Description

Technical Field

[0001] This utility model relates to the field of drilling rig structure technology, and in particular to a boom structure for a mining drilling rig. Background Technology

[0002] Currently, traditional deep-hole drilling in underground mines typically uses imported fully hydraulic drilling rigs. Traditional deep-hole drilling rigs mostly employ a horizontal boom structure. The drawback of this structure is that the rock drill is located in front of the propulsion mechanism. Due to the obstruction of the propulsion mechanism, compensation frame, and horizontal boom, the operator cannot see the drill bit and rock drill from the cab, making precise positioning impossible. The operator must carry the control platform to the front of the drilling rig to operate it, which is usually located in an unprotected tunnel, posing a significant danger. In underground mining, safety is paramount. Drill rig cabs meet FOPS & ROPS (Falling Rock Protection & Rollover Protection) standards, effectively ensuring operator safety. Operating from a cab that does not meet FOPS & ROPS standards would threaten the operator's life. Utility Model Content
