The invention relates to underground coal mine heading supporting equipment, in particular to self-moving advanced supporting equipment of a heading machine. The equipment comprises two groups of supports which are arranged back and forth, wherein a front support implements net installation by adopting a slewing beam to support an exposed top plate; a rear support is responsible for pushing the front support to move. According to the equipment, with hydraulic pressure as power, the supports can be self-moved; the slewing beam supports, manages and controls the top plate in advance; as the net installation is implemented by skilfully using the slewing beam, and then an anchor rod is stricken, the damage to the top plate is furthest decreased; the safety of operators is protected, the labour production rate is improved, and the physical labour of workers is decreased; the problems of low efficiency, bad safety reliability, great labour intensity of the workers and the like of an existing supporting technology are solved; the needs of heading safety, high efficiency and rapid footage are met; the comprehensive mechanization of coal mine heading tunnel supporting construction is realized.
Description
technical field [0001] The invention relates to coal mine underground tunneling support equipment, in particular to a self-moving advanced support equipment of a roadheader. Background technique [0002] Advance support is one of the auxiliary measures taken ahead of tunnel face excavation to ensure the stability of tunnel excavation face. With the improvement of the mechanization degree of coal mine roadway excavation system, the application of high-power roadheader, and the popularization of bolt-mesh support method with large section of roadway, advance support is becoming more and more important. [0003] The previous excavation production process is that when the excavation machine is in the excavation process, after each cycle of coal cutting footage, it is necessary to use simple iron pipes to temporarily support the roof, and then use the bolter to drive the bolts and hang the nets, and the personnel are exposed to danger. Under the roof of the roadway, the support ...
