Abstract
The invention belongs to the technical field of anchor drills for underground excavation roadway support in coal mines, in particular relating to a hydraulic five-arm anchor drill for the coal mine. With the adoption of the hydraulic five-arm anchor drill provided by the invention, the problem of low supporting efficiency caused by that the traditional four-arm anchor drill for the coal mine cannot be applicable to roadway support in the need of five-anchor-rod support can be solved. The hydraulic five-arm anchor drill comprises an anchor drilling system, wherein the anchor drilling system comprises five drilling arms; three drilling arms are mounted on a fixed sliding rail; and two drilling arms are respectively mounted on a left-sliding sliding rail and a right-sliding sliding rail. The hydraulic five-arm anchor drill provided by the invention has the advantages of being more suitable for the roadway supported by using the five anchor rods, being more common in application, and better meeting requirements for efficiently and rapidly tunneling mine coal faces with high yield. The hydraulic five-arm anchor drill provided by the invention can be used with a continuous miner so that the driving speed can be increased to 1.7 times that of the four-arm anchor drill used with the continuous miner. Therefore, the contradiction between excavating and supporting can be solved and the hydraulic five-arm anchor drill provided by the invention has a wide market prospect.
