Hydraulic driving two-stage feeding dovetail groove guiding asymmetrically-arranged anchor drilling machine

Abstract

The invention belongs to the technical field of anchor drilling machines, in particular to a hydraulic driving two-stage feeding dovetail groove guiding asymmetrically-arranged anchor drilling machine, solving the problems existed in the conventional anchor drilling machine. A carriage assembly of the hydraulic driving two-stage feeding dovetail groove guiding asymmetrically-arranged anchor drilling machine comprises a carriage; the rear end of the carriage is of an outer dovetail shape; the rear end of the carriage and a front guiding pressure plate with an inner dovetail shape form a translational pair; a short feed oil cylinder and a long feed oil cylinder are respectively arranged outside the carriage assembly and symmetrically arranged at two sides; the back side of a frame assembly is connected to a rear guiding pressure plate; the rear guiding pressure plate is of the inner dovetail shape; the rear guiding pressure plate and an outer dovetail guide rail in the sleeve of a support column assembly form the translational pair; a drilling box assembly is arranged at the front side of a guiding connection plate; the back side of the guiding connection plate is provided with the inner dovetail shape; and the back side of the guiding connection plate and the carriage of which the front end is of the outer dovetail shape form the translational pair. The hydraulic driving two-stage feeding dovetail groove guiding asymmetrically-arranged anchor drilling machine, disclosed by the invention, has the advantageous effects of complete functions, compact structure, adaptability for various types of working conditions, convenience for installing on underground carrier equipment, high anchor drilling efficiency, good anchor installation quality, high automation degree and low labor intensity.

Description

technical field [0001] The invention belongs to the technical field of rock bolt rigs, and in particular relates to a hydraulically driven two-stage feed dovetail groove-guided asymmetrically arranged rock bolt rig. Background technique [0002] Bolt support is a fast, safe and economical roadway support method. It is the representative of advanced support technology and the development direction of coal mine roadway technology. Bolt support has been widely used in major coal-producing countries abroad. my country's bolt support has been using a single hydraulic or pneumatic bolter to drill holes and manually install the bolt. This single-body rock bolt rig is generally composed of three parts: the rotating mechanism, the propulsion mechanism and the power device. It is operated with low automation, high labor intensity, poor safety, slow operation speed, and difficult to control the quality of anchor protection. defect. Contents of the invention [0003] In order to so...
