Drill rod lifting mechanism, auxiliary continuous drill rod replacing device and control method

Abstract

The invention discloses a drill rod lifting mechanism, an auxiliary continuous drill rod replacing device and a control method. The drill rod lifting mechanism is provided with a platform, a position adjusting mechanism is arranged on the platform, a drill rod conveying body is carried on the position adjusting mechanism, and a drill rod placing seat is carried on the drill rod conveying body; the drill rod placing seat is conveyed along the drill rod conveying body, and the conveying mode of the drill rod conveying body is scraper conveying; and the position adjusting mechanism drives the drill rod conveying body to realize position adjustment in a three-dimensional space. Movement is flexible, safety is good, and work is reliable; multiple degrees of freedom are achieved, flexible arrangement can be achieved according to site space, and roadway adaptability is high; during construction, manual filling is not needed, labor force is liberated to the maximum extent, the operation auxiliary time is shortened, and the rod replacing efficiency of the drilling machine is improved.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a drill pipe lifting mechanism, an auxiliary continuous drill pipe replacement device and a control method. Background technique [0002] Power head drilling rigs are widely used in drilling construction such as water exploration and drainage, gas drainage, roof and floor grouting, and geological structure exploration. In recent years, with the rapid development of intelligent technology and the continuous improvement of the level of intelligence, power head drilling rigs have also undergone automation and intelligent upgrades. The automatic rod changing device has become the basic configuration of a new generation of power head drilling rigs. The structure of the automatic rod changing device is also different for the power head drilling rig according to different requirements. At present, most drilling rigs use an automatic rod changing device composed of a manipulator and a ...

Problems solved by technology

However, limited by the conditions of downhole use, the size of the pallet equipped with the drilling rig is small, and the number of drill pipes stored is also small

When the drill pipes in the tray are used up, they still need to be loaded manually, which does not liberate the labor force to the maximum extent, increases the auxiliary time of the operation, and affects the rod changing efficiency of the drilling rig to some extent.
