The invention discloses a
geological survey device for underground adverse
engineering, and relates to the technical field of
geological survey and
engineering construction. The problems that an existing
geological survey device needs to manually replace a
drill rod in use, the operation is troublesome in the replacement process, the
workload of workers is large, meanwhile, the replacement speed is low, and the working efficiency is low are solved. The device comprises a survey
machine body, wherein a set of rotating seats are rotationally connected to the right side of the survey
machine body; a set of
drill rod grabbing driving pieces are fixedly connected to the upper portion of the front end face of a grabbing seat; two sets of grabbing blocks are connected to the rear portion of the grabbing seat in an up-down sliding mode; and two sets of bottom
drill rod fixing driving rods are rotationally connected to the inner side of the lower portion of the survey
machine body. According tothe device, a series of actions such as automatic fixing of the drill rod on the lower portion, automatic loosening of the drill rod, automatic grabbing of the drill rod, automatic feeding of the drill rod and automatic tightening of the drill rod are achieved, automatic drill rod adding is achieved, the
automation degree is high, the operation of workers is greatly reduced, and the labor efficiency is improved.
