Non-cylindrical rock core surface acquisition apparatus

Abstract

The invention which relates to a non-cylindrical rock core surface acquisition apparatus belongs to the fields of geophysics and information storage technologies. The acquisition apparatus comprises a pedestal, fixtures, a table top elevating adjusting rod, a countertop, a camera, a connecting rod, a slide block connector, an annular guide rail, a drive shaft, timing belt wheels, a timing belt, adecelerator, a motor and the like. The pedestal is provided with an upper connecting frame, a lower part of the upper connecting frame is provided with the countertop by guide rails, and the countertop is provided with the fixtures; a fixed plate which is arranged on an upper part of the upper connecting frame is provided with the motor and the decelerator, and a middle part of the fixed plate isprovided with the drive shaft; and the annular guide rail is arranged on the lower fixed plate, the connecting rod is fixedly arranged on a lower part of the drive shaft by a nut, and the connecting rod is provided with the camera and a lantern. According to the present invention, the rock core is vertically arranged on the countertop, the camera can rotate around the rock core through a horizontal annular moving mechanism, so the rock core surface can be acquired. Current problems that surfaces of crushed rock cores can not be acquired and scanned because the rock cores which are arranged horizontally are rotated by rollers and cylindrical surfaces of the rock cores must be intact are overcome.

Description

Technical field: [0001] The invention relates to a non-cylindrical core surface acquisition instrument, which belongs to the technical field of geophysics and information storage. Background technique: [0002] Cores and cuttings are one of the most precious materials for underground mineral resources research. At present, the description of the oil content of cores and cuttings at home and abroad has been changed from the process described by human observation with the naked eye to the use of a fluorescence image high-resolution acquisition instrument, which greatly improves the acquisition accuracy and efficiency. However, when using the core Puguang cuttings image high-resolution collector to collect the outer surface image, the cylindrical core is placed horizontally on two parallel cylindrical rollers, and the core is driven by the rotation of the rollers. The camera of the collector is not fixed. The collector of this structure requires that the cylindrical surface of the ...

Problems solved by technology

However, when the high-resolution acquisition instrument for general light and cuttings images of rock cores is used to collect images of the outer surface, the cylindrical core is placed horizontally on two parallel cylindrical rollers, and the rotation of the rollers drives the rotation of the core. The camera of the acquisition instrument is not fixed. The collection instrument of this structure requires that the cylindrical surface of the core must be intact to rotate on the top roller, and the broken cylindrical surface core cannot rotate on the top roller, so the collection instrument cannot collect

But sometimes the surface oil content of some broken cores has very good research value, but because the existing image acquisition instrument cannot collect the surface oil content of broken cylindrical cores, a large number of broken cores are wasted, which wastes manpower and material resources. waste of core resources
