Four-arm anchor rod transshipment unit for coal mine

Abstract

The invention discloses a four-arm anchor rod transshipment unit for a coal mine, and belongs to the technical field of coal mine underground development equipment. According to the technical scheme, the four-arm anchor rod transshipment unit comprises a machine body part, two operation platforms, a conveying part, four onboard jumbolters, two front drilling arms, two angle-adjustable two-way sliding type drilling arm devices, a protection plate part, an electrical system and a hydraulic system. The machine body part is installed below the rear parts of the operation platforms, the two operation platforms are symmetrically arranged on the two sides of the front end of the machine body part correspondingly, the conveying part is installed in the middle of the machine body part, the four onboard jumbolters are installed on the two front drill arms and the two angle-adjustable two-way sliding type drill arm devices, and the two front drill arms are symmetrically arranged on the upper surface of the front end of the machine body part left and right; the two angle-adjustable two-way sliding type drill arm devices are symmetrically arranged on the upper surface of the middle section of the machine body part left and right; the protection plate part is installed on the left rear side of the machine body part; the electrical system is installed on the right rear side of the machine body part; and the hydraulic system is installed on the rear left side of the machine body part and located under the protection plate part. The problems that digging and anchoring connection is tight, and digging and anchoring operation is unbalanced due to digging and anchoring alternate operation can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of coal mine development equipment, and in particular relates to a four-arm bolt reloading unit for coal mines. Background technique [0002] At present, the domestic coal mine excavation roadway generally adopts the operation mode that the roadheader is equipped with a bolter, and the two machines are cross-adjusted, or the roadheader is equipped with an airborne bolter, and the bolting is alternated; Parallel operation of excavation and support cannot be fully realized, resulting in long auxiliary operation time, low excavation efficiency and high labor intensity. However, the operation mode of the roadheader's supporting bolt transfer unit is still in the stage of exploration and research due to the constraints of domestic coal mine geological conditions and supporting equipment. [0003] In view of the tight connection and unbalanced mining of coal mine roadway, it is urgent to develop a bolt transfer u...
