Engineering driller for automatically loading and unloading drill stem

Abstract

The invention discloses an engineering driller for automatically loading and unloading a drill stem, and particularly to a coal mining driller specific to end slope mining of an open mine. The engineering driller comprises a driller frame body; a driller platform which is arranged on the driller frame body and used for placing the drill stem and a propeller to be loaded and unloaded, wherein a loading-unloading drill stem transfer channel is arranged on the driller platform corresponding to the position between the drill stem to be loaded and unloaded and the propeller for placing the loaded and unloaded drill stem; a drill stem angle phase position adjusting mechanism, which is arranged at the bottom part of the driller platform and used for adjusting the circumference angle of the loading and unloading drill stems thereon, so that the drill stem is normally abutted; a drill stem horizontal transfer mechanism; a drill stem vertical transfer mechanism. The angle phase positions of the loading and unloading drill stems are adjusted from the bottom part of the driller platform, and the drill stem to be loaded and unloaded is transported; the engineering driller solves the problem that the drill stem angle phase position adjusting mechanism and the drill stem conveying device of the existed engineering driller need to be arranged at the side face of the driller, and construction channel space out of the driller shall be occupied independently, and auxiliary hoisting device needs to configure.

Description

technical field [0001] The invention relates to the technical field of engineering drilling rigs, in particular to an engineering drilling rig for automatically loading and unloading drill rods, in particular to a coal mining drilling rig for edge mining in open-pit mines. Background technique [0002] During the construction of engineering drilling rigs, especially for the mining of inclined coal seams in open-pit mines, the engineering drilling rig itself needs to be fixed to provide back support for the advancement of the drill bit. In order to save construction time and avoid frequent movement of the drilling rig, it is necessary After advancing the length of a drill rod, the propeller and the drill rod are separated and the drill rod is lengthened to continue drilling. [0003] The drill pipe that the coal mining system adopts in the prior art, such as Figure 9 As shown, it includes a first drill rod 101 to be loaded and unloaded, a second drill rod 102 for lengthening...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is to overcome that the engineering drilling rig in the prior art needs to be provided with a slide table and hoisting equipment on the side of the drill rig, and the drill pipe angle phase adjustment mechanism and the drill pipe conveying mechanism are arranged on the slide table, which needs to occupy a large amount of time. The construction channel space cannot be applied to the construction environment with less space, so an engineering drilling rig for automatically loading and unloading drill pipes is provided, and the engineering drilling rig includes:
