Automatic drill pipe loading device applied to downhole hydraulic drilling rig and having drill pipe storage function

Abstract

The invention discloses an automatic drill pipe loading device applied to a downhole hydraulic drilling rig and having a drill pipe storage function. The automatic drill pipe loading device comprisesa mechanical device and a power system, wherein the mechanical device comprises a drill pipe box and a manipulator mechanism; multiple drill pipes can be stored in the drill pipe box for one time; a geneva mechanism rotates for a proper angle and a drill pipe is pushed out by a hydraulic cylinder, the manipulator mechanism clamps the drill pipe and takes the drill pipe out, the drill pipe is overturned by a swing cylinder to a drilling coaxial position of the drilling rig and conveyed to the drilling rig in a sliding manner through a linear driving mechanism, and finally, automation of a drillpipe loading process is completed. Automatic loading and unloading of the drill pipes can be finished, original functions of a drill carriage are not changed, functions of the drill carriage are expanded, and automation degree of the drill carriage is improved.

Description

technical field [0001] The invention relates to a device for connecting drill pipes for an underground hydraulic drilling rig, in particular to an automatic rod loading device for an underground hydraulic drilling rig with a rod storage function, and belongs to the technical field of coal mining roadway excavation engineering. Background technique [0002] In the construction process of coal mining and tunnel excavation, hydraulic drilling rigs are often used to drill rock formations or conduct geological exploration, gas exploration, drilling and blasting holes, etc., and in the process of drilling rigs, it is necessary to continuously add drills Rod, in order to achieve the depth requirements of drilling. The process of adding drill pipes, including the handling, alignment, and pre-tightening of drill pipes, is mostly heavy and high in height, and the process of changing drill pipes is mostly manual loading and unloading, or semi-automatic loading and unloading. Due to th...

Problems solved by technology

If the drilling position is high, the worker needs to climb the drilling machine or use other auxiliary equipment, which not only increases the difficulty of changing the rod, but also has certain dangers.

In addition, when the drilling rig is working, it is generally close to the section, and factors such as falling rocks, dust, and noise also pose a great threat to the safety of workers
