Mountain cutting and rock drilling tunnel stone splitting machine

Abstract

The invention relates to a mountain cutting and rock drilling tunnel stone splitting machine, belongs to the technical field of stone splitting machines, and provides the mountain cutting and rock drilling tunnel stone splitting machine which solves the problems that field working is lack of electricity and power and is capable of achieving mechanical-electrical-hydraulic integration and saving manpower, high in efficiency, safe and environmentally friendly. The mountain cutting and rock drilling tunnel stone splitting machine comprises a chassis, a big arm, a small arm, a main machine body and a hydraulic system; the chassis, the big arm and the small arm are rotatably connected in sequence, and the small arm is connected with the main machine body through an angle adjusting device; the main machine body comprises three pushing oil cylinder sets, a gear case, a drill rod, a drill bit, splitting devices and a pushing slideway, the first pushing oil cylinder set is connected with the gear case through a universal coupling, the second pushing oil cylinder set and the third pushing oil cylinder set are each connected with the corresponding splitting device through a universal coupling, and the hydraulic system comprises a hydraulic motor, two overflow valves, six magnetic exchange valves, a high-pressure oil pump and a pressure meter. The mountain cutting and rock drilling tunnel stone splitting machine is mainly applied to the mountain cutting and rock drilling tunnel aspect.

Description

technical field

[0001] The invention relates to a rock splitter for rock-drilling tunnels, and belongs to the technical field of rock splitters. Background technique

[0002] With the rapid development of the national economy and the country's increasing demand for mineral resources, the importance of rock engineering and mining engineering has become increasingly prominent. In traditional rock and mining mining, whether it is surface mining or underground mining, the most basic work is to break the rock out of the rock mass. At present, most of the mining methods are drilling and blasting, concrete expansion and the use of breaking hammers. Considering the development of my country's economy, environmental protection and the safety of construction personnel, coupled with the increasing cost of explosives and the cumbersome approval procedures for blasting, and the geological disasters caused by the blasting method on the mountain, these are The social problems caused by tr...
