A drilling device

Abstract

The invention discloses a drill rod detection device. The drill rod detection comprises a drill rod and a guiding frame; the drill rod comprises an inserting calibrated rod and a hammering guiding rodwhich are arranged coaxially as well as a hammering disk arranged on the hammering guiding rod in a sleeving manner; the hammering disk and the hammering guiding rod are connected fixedly; the upperside of the hammering guiding rod is further sleeved with a steel hammer; through holes are formed in the hammering disk; rotating shafts rotationally connected with the hole walls of the through holes are arranged in the through holes; jacking rods are fixedly connected to shaft bodies of the rotating shafts; and the rotating shafts rotate to drive the jacking rods to jack the steel hammer and then release the steel hammer to enable the steel hammer to fall freely to hammer the hammering disk, so that the inserting calibrated rod is hammered into a to-be-surveyed soil layer. According to thedrill rod detection, the jacking rods are controlled by a driving motor to rotate, and the steel hammer is jacked and released during rotation of the jacking rods to fall to hammer a counting disk, sothat the workload of a worker is reduced greatly, and the condition that the worker gets tired easily after long-time operation is avoided.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a brazing device. Background technique [0002] Before the construction of the building, it is necessary to survey the condition of the foundation soil layer to understand the condition of the soil layer. Engineers and technicians can detect the concealed structure in the soil layer or estimate the allowable bearing capacity of the soil layer according to the number of hammering required for the drill rod to enter a certain depth of the foundation to be detected. Therefore, during the drilling process, it is necessary to accurately record the number of hammer blows required to enter the specified depth of the foundation. The current drilling needs to manually lift the steel hammer and then let go of the steel hammer, making it fall freely to hammer the drill rod so that the drill rod gradually penetrates into the foundation soil layer that needs to be surveyed.

Problems solved by technology

The current drilling needs to manually lift the steel hammer and then let go of the steel hammer, making it fall freely to hammer the drill rod so that the drill rod gradually penetrates into the foundation soil layer that needs to be surveyed. Repeatedly lifting the steel hammer will make the workers extremely fatigued , at the same time, it is also necessary to manually record the number of hammering

These operations have greatly increased the workload of the workers, and there are often inaccurate manual counts due to the negligence of the operators, resulting in inaccurate data obtained, and engineers and technicians cannot accurately judge the real situation of the ground.
