A Dynamic Loading and Unloading Rod Structure for Raise Drilling Rig

Abstract

The invention discloses a dynamic upper rod disassembling structure for a raise boring machine. The dynamic upper rod disassembling structure comprises a mounting base, a lifting arm, a cylinder, a driving sleeve, a sliding block, a shifting block and a clamping block, wherein the mounting base is connected with a rotary box body; the cylinder drum of the cylinder is connected with the mounting base through a cylinder drum hinge pin; the mounting base is connected with the lifting arm through the lifting arm hinge pin; the piston rod of the cylinder is connected with the lifting arm through the piston rod hinge pin; the sliding block is connected with the lifting arm through a sliding block pin; the sliding block is clamped into a sliding groove of the driving shaft; the shifting block is connected with a rotary power head machine head body through an upper hinge pin; the shifting block is connected with the clamping block through a lower pin shaft. By adopting the dynamic upper rod disassembling structure, a drilling rod of the raise boring machine can be rapidly clamped, so that a drilling rod can be rapidly disassembled, and the operation can be convenient.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, in particular to a dynamic loading and unloading rod structure for a raise drilling machine. Background technique [0002] Raise drilling rig is an important construction equipment in mine raise construction. During the construction process, the auxiliary operation time often becomes an important factor affecting the construction efficiency of raise drilling rig. How to quickly clamp the drill pipe to realize the quick disassembly of the drill pipe thread to reduce the auxiliary operation time is an important aspect that needs to be studied, and it is also an urgent problem to be solved to improve the operating efficiency of the raise drilling rig. As disclosed in Patent No. 201220347247.7, a down-the-hole drilling machine with a hydraulic rod unloading device includes a carriage, and a positioner seat plate installed on the carriage, and a through hole for receiving a drill rod is provi...
