Telescopic arm open-cut rock drilling jumbo with drill rod replacing device

Abstract

The invention relates to a telescopic arm open-cut rock drilling jumbo with a drill rod replacing device. The telescopic arm open-cut rock drilling jumbo comprises a cab, a chassis assembly, a propeller assembly, a telescopic arm, the drill rod replacing device, a rock drill, a control system and a power and air control system 36; the cab is arranged on a cab bottom plate of the chassis assembly, the control system is arranged in the cab, and the control system is connected with the power and air control system; the telescopic length, the pitching angle and the deflection angle of the telescopic arm, the elongation of a propelling beam and the pitching angle of the cab are controlled by the control system; the arm seat of the telescopic arm is fixedly arranged at the front end of the cab, the propelling beam is in sliding fit with the telescopic arm through a bracket on a compensation cylinder, the telescopic end of the compensation cylinder is fixedly connected to the propelling beam, and extending compensation of the propelling beam can be realized by stretching of the compensation cylinder; and the drill rod replacing device is fixed on the propelling beam and positioned below a transmission rod, and the rock drill is fixed at the upper end of the propelling beam. The multi-azimuth drilling requirement of the jumbo can be met, and the gravity center of the whole jumbo is kept stable.

Description

technical field [0001] The invention relates to a rock drilling rig, in particular to a rock drilling rig with a telescopic arm, and belongs to the technical field of hydraulic rock drilling equipment. Background technique [0002] At present, high-speed drilling machinery has been widely used in military and civilian fields in other developed countries. In the past two years, it has been widely used in civilian applications in my country. In fields such as transportation, energy, mining, geological disaster management, and urban construction, It is used for tunnel excavation, canal excavation, mining, construction of underground caverns and other projects. [0003] Excavator-type hydraulic cutting drilling rigs are used for effective operations in shallow holes, but the overall design of the system is simple, resulting in low work efficiency. At the same time, it has poor adaptability to rock hardness during work, and does not have a side swing mechanism, and the drilling ra...

Problems solved by technology

[0003] Excavator-type hydraulic cutting drilling rigs are used for effective operations in shallow holes, but the overall design of the system is simple, resulting in low work efficiency. At the same time, it has poor adaptability to rock hardness during work, and does not have a side swing mechanism, and the drilling range is also limited. , the boom is usually set at the tail of the drilling rig, the center of gravity is unstable when working or moving, and it does not have the function of vertical or upward drilling
