Abstract

The invention discloses a gadder with a safety supporting unit, used in raise borers. The gadder comprises the safety supporting unit; the safety supporting unit comprises a drill stand and hydraulic legs; the hydraulic legs comprise upper hydraulic legs and lower hydraulic legs; the upper hydraulic legs used for supporting a tunnel roof are vertically disposed above the drill stand and are horizontally aligned; the lower hydraulic legs used for supporting the drill stand are disposed below the drill stand and are perpendicular to the ground or of a certain angle relative to the ground. The gadder has the advantages that the hydraulic legs are provided, the problems that the existing upper and lower supports are difficult to adjust and prone to loosening, so that offset of drill pipes and the like occur are solved, a lot of manpower and resources are saved, work efficiency is greatly improved, two setting modes of the lower hydraulic legs, namely vertical and tilted modes, are provided to allow flexible adjustment of the drill pipes when the offset occurs, and the drill stand can be more stable and easy to operate during construction.

Description

technical field [0001] The invention relates to the technical field of raise drilling rigs, in particular to a drilling rig vehicle with a safety supporting device. Background technique [0002] In the construction of soft rock mines, the traditional manual excavation of small pilot shafts is used for the construction of shafts and inclined shafts, which has the disadvantages of difficult groundwater discharge, difficult slag removal, poor ventilation conditions, and difficulty in ensuring the construction safety of vertical crossing operations, making the vertical shaft The construction of inclined shafts and inclined shafts is more difficult, especially the construction of vertical shafts and inclined shafts with a height difference or a length greater than 100m is even more difficult. The use of raise drilling rigs to construct pilot wells is a safe, efficient, economical, short construction period and less resource allocation construction technology. [0003] Raise dril...
