Abstract

The invention discloses an extended ranging device for assisting a gamma ray detector in measuring a hole. The extended ranging device comprises a plurality of knuckles and connecting rotating shaftsfor connecting the adjacent knuckles. The connecting rotating shafts include first rotating shaft connecting pieces, second rotating shaft connecting pieces and rotating shaft latches; windows for accommodating the second rotating shaft connecting pieces are arranged at the middle parts of the first rotating shaft connecting pieces; the first rotating shaft connecting pieces include first back surfaces and first fitting surfaces; and the second rotating shaft connecting pieces include second back surfaces and second fitting surfaces. First connecting surfaces and second connecting surfaces arearranged at the two ends of the knuckles; the first back surfaces are connected with the first connecting surfaces of the knuckles; and the second back surfaces are connected with the second connecting surfaces of the adjacent knuckles. The extended ranging device has advantages of light weight, small size, and high portability; and the working efficiency of the hole measuring is improved and thelabor intensity of the hole measuring is reduced.

Description

technical field [0001] The invention relates to the field of auxiliary tools for radiation detection, in particular to an extension ranging device for assisting gamma-ray detectors in measuring holes. Background technique [0002] The γ-ray detector is the main detection instrument for radioactive minerals. According to the difference in detection purposes, the γ-ray detector can be divided into a surface detector and a borehole detector. The borehole detector is used to detect γ-rays on the surface of the hole at different depths strength. [0003] Existing borehole detectors mainly include a cylindrical probe, a host, and wires used to connect the probe and the host. The length of the wire determines the maximum detection depth of the borehole detector; when the borehole detector is used to measure holes, its probe passes Use the screw to advance into the hole step by step. During the advancing process, the screw needs to be continuously replenished. During the advancing ...
