Abstract

The invention relates to hole depth detection equipment, in particular to blasting drilling hole-forming hole depth detection equipment. The invention aims to provide the hole depth detection equipment for the formed hole of the blasting drill hole, which is relatively high in measurement accuracy. The hole depth detection equipment comprises a placing plate, supporting plates, a control box, a first key, cantilevers and the like, the supporting plates are symmetrically arranged on the left side of the top of the placing plate front and back, the cantilevers are arranged on the right sides of the upper portions of the supporting plates, the control box is arranged in the middle of the front side of the top of the placing plate, and the first key is arranged on the upper left portion of the front side of the control box. A steel wire measuring rope can be loosened by taking a first gear motor as a driving force, then the steel wire measuring rope can be downwards transmitted into a blast hole by taking a second gear motor as a driving force, and then the steel wire measuring rope and an elastic arc-shaped rod can be driven to shake up and down by taking a brushless motor as a driving force; the elastic arc-shaped rod is prevented from clamping the hole wall, and the measurement accuracy is ensured.

Description

technical field [0001] The invention relates to a hole depth detection device, in particular to a hole depth detection device formed by blasting drilling. Background technique [0002] Drilling and blasting method has always been the main construction method for rock excavation of underground buildings. After drilling a hole, people need to carry out hole depth detection on the hole, so as to judge whether the hole meets the requirements. [0003] Patent application CN204924224U, published on 20151230, discloses a borehole depth detector for cast-in-place piles, which includes a casing, a wire weight, a measuring wire, a winding shaft, a crank handle and an electronic counting device, and the winding shaft is arranged in the casing; The electronic counting device includes a Hall sensor, an A / D conversion chip, a single-chip microcomputer, a display screen, a switch button and a reset button, the Hall sensor is connected with the A / D conversion chip, the A / D conversion chip i...
