Abstract

The invention discloses a roadheader suitable for vertical shaft drilling in presence of a pilot shaft. The roadheader comprises a main body rack, a rock breaking drill bit, a drive system, a support system and a control system, wherein the drive system comprises a rotation drive sub-system and a pushing drive sub-system; the rock breaking drill bit, the rotation drive sub-system, the pushing drive sub-system, the support system and the control system are mounted on the main body rack respectively; the rotation drive sub-system is in transmission connection with the rock breaking drill bit; the rock breaking drill bit comprises a cutter head and a guide device. The roadheader can be used for drilling vertical shafts with designed diameters sequentially in the presence of the pilot shaft, and when the roadheader is used for vertical shaft drilling, correction equipment is not required under the condition that the borehole deflection degree of the pilot shaft is guaranteed.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a roadheader suitable for drilling shafts with guide shafts. Background technique [0002] In the prior art, the existing rock formation mine construction projects mostly adopt the common method of sinking construction, requiring the staff to go down to the narrow and small excavation working face with a depth of several hundred meters, and use drilling rigs to drill blast holes, pack explosives, and work on the working face. Blasting, lifting the rocks broken by blasting to the ground through buckets, draining the working face, and then performing support and other operations. The level of mechanization is low, the labor input is high, the working environment is difficult, the safety conditions are poor, accidents occur frequently, and the blasting disturbs the surrounding rock greatly, the stress of the original rock changes greatly, and the support is difficult. Among them, ro...
