Abstract

The invention discloses a hydraulic anti-jamming control system for a drill loader. The hydraulic anti-jamming control system comprises a plunger pump, a multi-path reversing valve, a pilot oil source valve set, a pilot oil control valve set, an anti-jamming valve set, a pushing oil cylinder, an impactor and a rotating motor, wherein an oil outlet of the plunger pump is respectively connected with the multi-path reversing valve and the pilot oil source valve set; oil return holes of the multi-path reversing valve and the pilot oil source valve set are connected with an oil tank by a cooler; a first joint of the multi-path reversing valve is connected with the anti-jamming valve set; the anti-jamming valve set is connected with the pushing oil cylinder by a balance valve set; a second joint of the multi-path reversing valve is connected with the impactor; and a third joint of the multi-path reversing valve is connected with the rotating motor. The hydraulic anti-jamming control system for the drill loader can set multi-stage pushing and impact pressure, so as to be adaptive to different geological conditions, thereby effectively and actively preventing jamming; moreover, the control system can control the impactor and the pushing oil cylinder to transfer to a light-impact and light-pushing operation during jamming, so as to repair drilling and improve the anti-jamming effect.

Description

technical field [0001] The patent of the present invention relates to the technical field of mining comprehensive tunneling equipment, in particular to a hydraulic anti-jamming control system of a mining drilling machine. Background technique [0002] Drilling machine is a comprehensive tunneling equipment integrating drilling, loading and conveying. It is mainly used in the tunneling of small and medium-sized hard rock roadways in coal mines in my country, and can also be used in tunneling projects in metallurgy, railways, highways, hydropower and other departments. The prospects are extremely bright. The drilling rig is mainly composed of a raking unit, a drilling rig unit, a feeding hopper, a traveling unit, a frame unit, a supporting unit, and a transport unit. [0003] The drilling machine mainly adopts the full hydraulic rock drilling method. Due to the harsh working environment and complex and changeable working conditions of the drilling machine, it is easy to get st...
