Free-falling-body-based frame column type electric lifting drill rod detection device and implementation method

Abstract

The invention relates to the technical field of drill rod detection, and particularly relates to a free-falling-body-based frame column type electric lifting drill rod detection device and an implementation method. The mode that a rotating wheel drives a jacking rod to rotate is adopted, the jacking rod is matched with a convex block of a heavy hammer, the heavy hammer can be jacked up firstly, then the heavy hammer and the convex block are separated, and the heavy hammer does free falling body to hammer a stress reset assembly and acts on a steel drill rod mechanism for drill rod detection; the stress reset assembly and the steel drill rod mechanism are matched through clamping jaws and tooth grooves, and the acting strength on the steel drill rod mechanism is the same every time; the clamping jaws are further provided with pull ropes, the pull ropes are tensioned to enable the clamping jaws to be folded and staggered with the tooth grooves, and therefore the steel drill rod mechanism cannot be hindered when moving upwards; and a drill rod pulling assembly is arranged, a drill rod pulling motor drives a lead screw to rotate, a drill rod pulling plate moves upwards under the action of the lead screw, the drill rod pulling plate clamps a convex strip and pulls the steel drill rod mechanism upwards, and therefore the steel drill rod mechanism is pulled up from the ground, the steel drill rod mechanism and the stress reset assembly can be restored to the initial relative position, and subsequent repeated implementation is facilitated.

Description

technical field [0001] The invention relates to the technical field of brazing, and relates to a column-type electric lifting brazing device based on free fall and an implementation method. Background technique [0002] Brazing exploration is to inspect the soil layer below the bottom of the foundation pit according to the regulations after the excavation of the foundation pit reaches the design elevation, judge the softness and hardness of the soil, and detect whether there are pits, ancient tombs, ancient wells, air-raid shelters and underground Burial objects, etc. [0003] Drilling probes generally use steel bars as steel drills, and the drill tip is tapered. When drilling, the steel brazing is driven into the soil with a sledgehammer falling from a high place, and the number of hammering for each certain distance is recorded, based on which the softness and hardness of the soil can be judged. [0004] The Chinese utility model patent with the patent number CN202021259...

AI Technical Summary

Problems solved by technology

First of all, it lacks the function of pulling out the drill rod; after the drill rod is hammered into the ground, it is difficult to pull out the drill rod later, and generally requires additional equipment

Secondly, the linkage assembly adopts the cooperation of the stop groove and the stop pawl, so that the sleeve rod acts on the casing, but after the drilling is completed, it is inconvenient or even unable to realize the reset between the sleeve rod and the casing, and cannot be reused
