Rock sampling and detecting device in geological drilling

Abstract

The invention discloses a rock sampling and detecting device in geological drilling, and belongs to the technical field of geological drilling, the rock sampling and detecting device comprises a base, a sampling mechanism for collecting rock is arranged on the base, and a detecting mechanism for detecting the collected rock is arranged on the side edge of the sampling mechanism; the sampling mechanism comprises an adjusting mechanism which is mounted on the base and is used for changing the position of the device, a drilling mechanism is arranged on the adjusting mechanism, the detection mechanism comprises a fixing mechanism for fixing a sample rock, and a testing mechanism for detecting the pressure of the rock is arranged on the fixing mechanism; through cooperation of a fixing cylinder, a drilling cylinder and a grooving cylinder on the drilling mechanism, the adaptation rate can be increased, two clamping plates arranged in a placement groove extrude each other to extrude an internal rock sample, and the rock is conveniently taken out; meanwhile, through mutual cooperation of three arc-shaped extrusion plates on the fixing mechanism, rocks of different sizes can be fixed, pressure is given to the sample rocks from different directions for fixing, and the stability of the sample rocks is improved.

Description

technical field [0001] The invention belongs to the technical field of geological drilling, in particular to a rock sampling detection device in geological drilling. Background technique [0002] In geological exploration, drilling methods are often used to observe the natural state of rock and soil layers and the geological structure of each layer. Drilling refers to the use of drilling rigs to drill holes in the layers to identify and divide subsurface layers, and to take samples along the depth of the drill holes. A method of exploration that yields deep geological data. In the existing geological drilling, after the rock samples are drilled, the rock samples are generally inside the drill pipe, and then brought out with the removal of the drill pipe, but when carrying, the rock is not tightly fixed, so that the samples are in the original borehole. It is not easy to take out inside, which increases the difficulty of workers' operation. At the same time, the samples are ...

AI Technical Summary

Problems solved by technology

In the existing geological drilling, after the rock samples are drilled, the rock samples are generally inside the drill pipe, and then brought out with the removal of the drill pipe, but when carrying, the rock is not tightly fixed, so that the samples are in the original borehole. It is not easy to take out inside, which increases the difficulty of workers' operation. At the same time, the samples are generally equipped with a fixed testing platform when testing. However, the samples taken out are different in size, and different testing platforms need to be customized, resulting in waste of cost, and pressure testing is carried out on the testing platform. When the rock is not firmly fixed, it is easy to slip during the pressure measurement, resulting in inaccurate pressure measurement
