Abstract

The invention discloses a hydraulic control system of a dust removal and outburst prevention integrated heading machine and belongs to the technical field of excavation equipment. The hydraulic control system comprises a heading machine host control system, a dust removal fan motor control system, an outburst prevention drilling machine control system, a pump station system and a control oil system; a heading machine host, a dust removal fan motor and an outburst prevention drilling machine share the same pump station system, so that the integration level of the hydraulic system is improved, and meanwhile, the utilization ratio of a pump station is increased; by using the outburst prevention drilling machine control system, the drilling range of the outburst prevention drilling machine is widened, the slip problem caused when the drilling machine drills at a large inclined angle is effectively solved, and the safety and the reliability of outburst prevention drilling are improved; a load-sensing technology is adopted in the hydraulic control system, so that the efficiency of the control system is increased, and a better energy-saving effect is achieved; and a load-sensing proportional directional valve is adopted in the hydraulic control system, so that the control precision of an executive component is improved, and the hydraulic control system is simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of excavation equipment, in particular to a hydraulic control system of a roadheader integrating functions such as excavation, dust removal, geophysical exploration and anti-outburst drilling. Background technique [0002] The roadheader is an excavation equipment specially used for excavating underground roadways. With the development of technology, the roadheader in the existing technology has integrated technical applications such as excavation, dust removal, geophysical exploration and anti-outburst drilling, and can realize continuous cutting, loading, and transportation. Operation. [0003] Yet there are many shortcomings in the roadheader hydraulic control system in the prior art, as: [0004] 1. The load sensitivity of the hydraulic control system is poor, resulting in low efficiency and high energy consumption of the hydraulic control system. [0005] 2. The sensitivity of the reversing valve used...
