The invention provides an electro-hydraulic control system of an anchor cable drilling machine. The electro-hydraulic control system comprises a variable pump, a feeding hydraulic oil cylinder, a rotating speed sensor, a controller, an anti-explosion electromagnetic proportional multi-way valve, a plurality of target hydraulic oil cylinders and a plurality of pressure sensors, wherein the variablepump is connected with the anti-explosion electromagnetic proportional multi-way valve through a pipeline; all plate valves in the anti-explosion electromagnetic proportional multi-way valve are connected with the plurality of target hydraulic oil cylinders through pipelines respectively; and the multiple target hydraulic oil cylinders are provided with detection points at the piston rod extending-in-place limit position and the piston rod retracting-in-place limit position. The controller controls the explosion-proof electromagnetic proportional multi-way valve according to a plurality of pressure values obtained by pressure detection of detection points by the plurality of pressure sensors, the rotating speed acquired by the rotating speed sensor and the feeding speed and the feeding displacement of a drilling box detected by an encoder, so that the automatic control of the anchor cable drilling machine is realized, and the problems that an existing anchor cable drilling machine control system cannot achieve remote operation, the labor intensity of workers is high and the automation level is low are solved.
Description
technical field [0001] The invention relates to the technical field of cable-anchor drilling rig control, in particular to an electro-hydraulic control system for a cable-anchor drilling rig. Background technique [0002] Anchor cable drilling rigs are used for drilling and resin mixing in anchor cable support work in coal mine roadways. Anchor drilling rig is the key equipment for bolt support, which has a great influence on the quality of anchor cable support and plays an indispensable role in coal mine safety production. [0003] However, the existing hydraulic control system of cable anchor drilling rigs has disadvantages such as low degree of automation, high labor intensity of workers, low support efficiency, harsh working environment, incapable of remote control, and poor safety. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] For this reason, the present...
