Mechanism for automatically changing drill rod

Abstract

The invention discloses a mechanism for automatically changing a drill rod, comprising a centre shaft and an end part clutch combination, a rotary shaft combination, a frame combination, a swing mechanism combination, a positioning oil cylinder and six tension shafts. The centre shaft and the end part clutch combination comprises a centre shaft component, two sets of drill rod storing discs, an end part disc clutch, an axial retainer ring A and two sealing rings A. The rotary shaft combination comprises two sets of claw combinations, a rotary shaft, a sealing ring D, a sealing ring C, an axial retainer ring B, a shaft-end press cover, a bolt G, a sealing pad B and an O-shaped ring D. The frame combination comprises an upper frame combination, a lower frame combination, four sets of vertical column welding pieces, and two retainer ring welding pieces which are provided with openings. The swing mechanism combination comprises an oil cylinder with a grab rod, a spline handle, a connection arm, and a swing oil cylinder. The mechanism for automatically changing the drill rod has the following advantages: the mechanism can be applied on mining drill carriages to automatically change the drill rod, so that the use efficiency of the mining equipment is greatly improved, the production efficiency is improved, and the labor strength of changing the drill rod is reduced.

Description

technical field [0001] The invention relates to a mechanism for exchanging drill rods, in particular to an automatic exchanging mechanism for drill rods, which is applied to mining rigs. Background technique [0002] At present, the mining drilling rigs used in the mining operations of metal mines such as copper and iron mines, as well as the expansion engineering of large-section engineering tunnel sections, all use manual replacement of drill rods for mining operations and expansion operations, that is, operation When drilling or returning drill rods, manual replacement of drill rods is required, and 17 to 27 drill rods need to be frequently replaced, and manual replacement of drill rods is labor-intensive, low in production efficiency, and poor in site operation safety. The above are the deficiencies in the prior art. Contents of the invention [0003] The purpose of the present invention is to provide an automatic drill rod exchange mechanism, which is applied to a mi...
