Abstract

The invention discloses a stone excavation fragmentation device for a fractured rock layer and a method for installing and using the same. The fragmentation device comprises a fragmentation drilling device, a hydraulic energy supply device and a walking system. The fragmentation drilling device comprises a vertical drilling head, an expander, a positioning oil cylinder, a fragmentation vibrator, avertical adjustment oil cylinder and a fragmentator oil pump. The hydraulic energy supply device includes a fragmentator positioning telescopic arm, a fragmentator telescopic arm supporting frame, afragmentator oil supply system and an oil supply pipe. The walking system includes a generator set, an operation room, a walking track, a walking system supporting frame, a power line and a control line. The stone excavation fragmentation device intends to replace a traditional construction process with an automatic large-scale mechanical device to achieve the purpose of reducing safety risks andimproving production efficiency. By technical comparison analysis and defect analysis of current stone excavation construction links of the fractured rock layer, we find that a conventional drilling and blasting excavation process has the problem that a large amount of fire work materials must be used and the safety guarantee coefficient is low.

Description

technical field [0001] The invention relates to the technical field of highway engineering construction, in particular to a device for excavating and fragmenting rock formations and a method for using the same. Background technique [0002] As domestic and international communities pay more and more attention to safety issues, the field of rock blasting has always been a major source of danger. How to reduce the safety risk caused by stone excavation is a focus in the construction field. The current development trend of stonework excavation in broken rock formations is roughly as follows: ①Due to the development of large-scale mechanization in the construction field of highway engineering, the mechanical operation methods for stonework excavation in broken rock formations are more and more widely used, which makes the fragmentation Large-scale mechanized production of rock excavation has become a trend; ②The current construction period of highway engineering is getting shor...
