Positioning device convenient in mine drilling position seeking

Abstract

The invention discloses a positioning device convenient in mine drilling position seeking. The positioning device comprises a hole position indicating rod. A hanging ring is disposed at the upper end of the hole position indicating rod. A sleeve is disposed on the hole position indicating rod. At least three support legs are disposed at the outer edge of the sleeve. Each support leg includes an upper support leg and a lower support leg which are connected through a threaded shaft, and a ball-shaped support part is disposed at the bottom of the lower support leg. The positioning device further comprises a position sensing device disposed on the hole position indicating rod. The position signals of the position sensing device is received by a receiver. The positioning device is simple in structure, convenient to machine, low in cost, convenient to use, convenient to store, wind resistant and falling resistant, recyclable, and capable effectively increasing work efficiency.

Description

technical field [0001] The invention belongs to the field of mining machinery, and relates to a drill hole locator, in particular to a mine drill hole position locator that is easy to find. Background technique [0002] It is well known that perforation blasting is the most important link in the production process of open pit mines. The quality of perforation blasting directly affects the overall production of open-pit mines. The layout of drilling positions is the first step before perforation. The main factor for whether the drilling rig can perform construction according to the design is the accurate layout of drilling positions. Therefore, the layout of drilling positions is particularly important in open-pit mines. [0003] The layout method of the existing open-pit mine drilling layout is: according to the perforation design, use a ruler to measure and determine the drilling position, and the technicians use the stones in the site to pile up a stone pile as a sign at ...

AI Technical Summary

Problems solved by technology

[0004] 1. The positions of the holes are distributed more, and it is not easy to find when the drilling rig is drilling;

[0005] 2. Since each hole is made of 3-4 stones of different sizes and shapes, there is a certain deviation between the arranged holes and the actual position, and the point error is 10-30cm

[0006] 3. Heavy workload

Each hole requires 8 kg or more stones. It is easy to pick up stones when the weather is good, but it is necessary to pick up stones from muddy water and snow in rainy days and winter, which also increases the difficulty of hole layout.

At the same time, rocks are also easily covered by heavy snow, making it difficult for drillers to accurately locate holes
