Abstract

The invention relates to a rock-drilling drill carriage with a foldable arm and an automatic drill rod replacing device, which belongs to the technical field of rock-drilling machinery equipment. A cab is mounted on a rotating platform of a chassis assembly, and the rotating platform is located above a framework platform and can circularly rotate; a control system of the cab is connected with a power and pneumatic control system, and an operating and displaying terminal is a liquid crystal display screen; the extension angle of the foldable arm, the extension quantity of a pushing beam, the rotation angle of the cab and actions of a rock-drilling machine are controlled by the control system; the foldable arm is integrally connected onto a drill carriage platform via an auxiliary arm and an arm folding cylinder, the pushing beam and the foldable arm are mounted in a slide fit manner via a supporting plate on a bracket, the supporting plate is sleeved in a double-side bending structure of the pushing beam, and a telescopic end of an extending cylinder is fixedly connected onto the pushing beam; and the drill rod replacing device is fixed on the pushing beam and located below a transmission rod, and the rock-drilling machine is fixed at the upper end of the pushing beam. System efficiency is high, integral stability is good, and drill rods can be replaced automatically.

Description

technical field [0001] The invention relates to a rock drilling rig with a foldable boom, in particular to a rock drilling rig with a foldable boom provided with a drill changing device, which belongs to the technical field of rock drilling machinery. 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. The use of mechanical equipment can improve the mechanization level and work efficiency of engineering blasting, and at the same time reduce energy consumption and labor intensity of workers. [0003] At present, the excavator-type hydraulic cutting drilling rig commonly u...
