Embodiment 1

[0046] This embodiment provides a rock drilling jumbo, which includes a walking system 1, a frame 2, a power system 3, a hydraulic system 4, an electrical system 5, a drilling arm assembly 6, a propulsion beam assembly 7 and a replaceable rock drilling Working component 8.

[0047] The walking system is a crawler vehicle, and the frame is arranged on the crawler vehicle, so as to move the position of the frame and other parts installed on the frame by the crawler vehicle, and adjust the frame and Other components mounted on the frame provide effective support.

[0048]The frame includes a front frame and a rear frame, and the front frame and the rear frame are all fixed on the chassis of the tracked vehicle, refer to figure 1 , the front frame is fixed on the left side of the tracked vehicle, and the rear frame is fixed on the right side of the tracked vehicle.

[0049] The power system, hydraulic system, electrical system and wireless remote control system are all installed...

Abstract

The invention discloses a drill jumbo comprising a travelling system, a rack, drill boom assemblies, propelling beam assemblies and replaceable drilling components. The rack is fixed to a chassis of the travelling system so as to move the rack through the travelling system; the drill boom assemblies are fixed to the frame; the propelling beam assemblies are fixed to the corresponding drill boom assemblies; the replaceable drilling components are fixed to the propelling beam assemblies correspondingly. The drill jumbo has the advantages that fast modular installation can be realized when the replaceable drilling components are replaced, parameter readjustment is not required, and the replaceable drilling component on one drill boom assembly is replaced within 10 minutes. The most rational drilling method can be selected according to requirements on the construction site, and the drill jumbo is highly adaptable to formations from soft formation to extremely hard formation as well as highly adaptable to non-blasting construction requirements and non-blasting and drilling blasting combined construction requirements.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a rock drilling jumbo. Background technique [0002] Since the United Kingdom began to build the 770-meter-long Taylor Mountain single-track tunnel and the 2,474-meter-long Victoria double-track tunnel on the railway pulled by steam locomotives in 1826, Britain, the United States, France and other countries have successively built a large number of railway tunnels. In 1861, when building the Shannis Peak Railway Tunnel across the Alps, a pneumatic rock drill was used for the first time instead of manual drilling. In 1867, when the Husak Railway Tunnel was built in the United States, nitroglycerin explosives were used instead of black powder, which further developed the tunnel construction technology and speed. [0003] Since the 1960s, the level of mechanized tunnel construction has been greatly improved. Full-face hydraulic rock drilling rigs and other large construction m...
