Abstract

The invention discloses a fragile coal seam rapid excavation and anchor protection matching device. The matching device is mainly composed of a machine body, a cutting device, a hydraulic device, a shield beam and the like, wherein a transmission rotating shaft I is additionally arranged on the outer side of a crawler belt guiding and tensioning device on the lower portion of a heading machine, abelt guiding and tensioning device is arranged on the machine body, a roller capable of installing an iron gauze is arranged at the joint of the hydraulic device and the shield beam and installed on atransmission rotating shaft III, the transmission rotating shaft I is connected with one side of a transmission rotating shaft II on the belt guiding and tensioning device through a belt I, the otherside of the transmission rotating shaft II is connected with the transmission rotating shaft III driving the roller to rotate through a belt II, and a hydraulic drilling machine for fixing an anchorcable (rod) is fixed on the machine body. According to the matching device, a crawler belt advances to drive the iron gauze to be automatically laid above a roadway, anchoring and protecting are carried out in time, safety and time saving are achieved, and the working efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a roadheader, in particular to a supporting device for rapid tunneling and anchor protection of easily broken coal seams. Background technique [0002] At present, with the widespread use of comprehensive mechanized roadheaders (referred to as "mechanized roadheaders") for underground mining in coal mines, the efficiency of roadway excavation has been greatly improved compared with the traditional "drilling and blasting" operation method. However, due to the influence of rock conditions on the roadway roof, especially during coal roadway excavation, when the roof coal seam is easily broken, the pressure on the coal seam roof is high, and coal wall slabs are prone to occur at the front, which poses a large safety hazard. In order to ensure the safety of the operation, the existing measures are usually to set up the leading anchor rods at the two sides and hang the protective net at...
