Geological prospecting device

Abstract

The invention discloses a geological prospecting device, which comprises an underframe, a prospecting drilling machine base is fixedly connected to a side position of the top end of the underframe, asteel frame is fixedly connected to one end of the prospecting drilling machine base, and a convenient connecting, detaching and positioning mechanism is fixedly connected to the position, corresponding to the steel frame, of one end of the prospecting drilling machine base; the convenient connecting, detaching and positioning mechanism comprises a connecting disc, a rotary base, a cavity, a rotary groove, a positioning groove, a positioning block, a roller, a reset spring, a sliding block, a lifting ring, a bump, a connecting rod and a movable sleeve ring. The device is scientific and reasonable in structure and safe and convenient to use, the convenient connecting, detaching and positioning mechanism is arranged, the movable sleeve ring is pushed to ascend through extension of an electric telescopic rod, therefore, clamping blocks are pushed through the movable sleeve ring to move along a movable groove, the distance between the clamping blocks is reduced, the clamping blocks clamp adrill rod according to the diameter of the drill rod, the drill rod is fixed, and meanwhile a rotating block is pushed in the ascending process of the movable sleeve ring.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a geological exploration device. Background technique [0002] Geological prospecting is an investigation and research activity in which the geology is surveyed and detected through various means and methods to determine the appropriate bearing layer, determine the foundation type and calculate the foundation parameters according to the foundation bearing capacity of the bearing layer. The exploration methods mainly include pits, Trenching, drilling and geophysical prospecting, etc., in which drilling is performed by drilling holes into the ground to collect soil for detection; [0003] However, when the existing exploration drilling rig connects the drill pipes, the drill pipes are not fixed, so that the drill pipes are prone to offset when they are connected, causing misalignment between the drill pipes, which affects the efficiency of the drill pipe connection. ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a geological prospecting device, which can effectively solve the problem that the exploration drilling rig proposed in the above background technology does not fix the drill rod when connecting the drill rod, so that the drill rod is prone to offset when connecting, and the gap between the drill rods Misalignment occurs, which affects the efficiency of the drill pipe connection
