A core sampling drilling rig

Abstract

The invention provides a core sampling drilling rig, which includes a main rack, a walking mechanism, a power head, an automatic rod feeding mechanism and an automatic rod taking mechanism. The automatic rod feeding mechanism includes a storage mechanism, a transporting mechanism and a supporting mechanism, and the automatic taking mechanism includes a lifting mechanism, a grasping spindle attitude transformation mechanism and a manipulator grasping mechanism. According to the technical scheme, the core sampling drilling rig has the effects that structural design of the automatic rod feeding mechanism is ingenious, and automatic transmission of rod pieces with two or more sizes can be realized; structural design of the automatic rod taking mechanism is ingenious, alternate automatic grasping of the rod pieces with two or more different diameters and sizes can be realized, the rod pieces are automatically and additionally installed onto the inclined or vertical power head, or the rod pieces on the power head are disassembled in sequence for recycling, core sampling misering, rotary excavating misering, well drilling or deep hole drilling and other drilling functions can be achievedby simply changing a drilling tool at the tail end; and the degree of automation of the whole core sampling drilling rig is high, automation of core sampling or outer casing pipe loading and unloadingis realized, and tedious manual operation is avoided.

Description

technical field [0001] The invention relates to the field of geological engineering exploration equipment, in particular to a core sampling drilling rig. Background technique [0002] With the continuous development of geological engineering exploration equipment, fully hydraulic core sampling drilling rigs have become the main force of exploration equipment and have made great contributions to the development of geological exploration. However, the fully hydraulic core sampling drilling rigs currently on the market have the defects of low automation and intelligence, and cannot automatically and alternately install or disassemble two or more drill pipes or casings of different sizes during inclined or vertical drilling. It needs to be manually added or disassembled one by one. Moreover, the core sampling rig is not fully integrated with functions such as real-time monitoring of the overall situation and the coring process, real-time monitoring of drilling parameters, autom...

Problems solved by technology

However, the fully hydraulic core sampling drilling rigs currently on the market have the defects of low automation and intelligence, and cannot automatically and alternately install or disassemble two or more drill pipes or casings of different sizes during inclined or vertical drilling. Need to rely on manual installation or disassembly one by one

Moreover, the core sampling rig is not fully integrated with functions such as real-time monitoring of the overall situation and the coring process, real-time monitoring of drilling parameters, automatic adjustment of the mast inclination, and remote precise positioning of the rig position information.

In addition, the expansion ability is poor, and the function expansion cannot be directly performed, and the drilling rig cannot be used to realize the online in-situ detection of the rock and soil layer

[0003] In-situ detection is a very important process in the core sampling drilling process. However, none of the core drilling rigs on the market is equipped with a systematic in-situ detection device. Manpower, poor working environment, and potential safety hazards
