Abstract

The invention relates to the technical field of rock drilling equipment, in particular to an anti-borer-clamping hydraulic control system and rock drilling equipment. The anti-borer-clamping hydraulic control system comprises an impact control module, a propelling pressure control module, a propelling speed control module, a variable pump, a rotation motor and a propelling oil cylinder; the impact control module comprises a first proportion reversing valve communicated with a load feedback port of the variable pump and an oil tank, and a guide control port of the first proportion reversing valve is connected with an oil inlet of the propelling oil cylinder; the propelling pressure control module comprises a third proportion reversing valve communicated with the air inlet of the propelling oil cylinder and the oil tank; the propelling speed control module comprises a guide proportion throttling valve connected between the oil tank and the oil inlet of the propelling oil cylinder, and guide control ports of the third proportion reversing valve and the guide proportion throttling valve are connected with an oil inlet of the rotation motor. The rock drilling equipment comprises the anti-borer-clamping hydraulic control system. The anti-borer-clamping hydraulic control system and the rock drilling equipment are in self-adaption with various rock strata and are matched with reasonable impact pressure, propelling pressure and propelling speed.

Description

technical field [0001] The invention relates to the technical field of rock drilling equipment, in particular to an anti-jamming hydraulic control system and rock drilling equipment. Background technique [0002] In related technologies, in tunnel rock drilling operations, hydraulic rock drilling equipment is widely used in railway, highway tunnels and other mine excavation occasions due to its advantages of high rock drilling efficiency, low pollution, and high safety. [0003] The rock drilling principle of the hydraulic rock drill is generally the same. The impact energy generated by the rock drill will be transmitted to the drill bit through the connecting device, and the impact energy will act on the rock formation to break the rock. The rock is crushed by the action, and the crushed rock is taken out of the blasthole by water flushing and drill bit rotation. At the same time, the rock drill propulsion cylinder drives the rock drill to advance, so that the drill bit con...
