Abstract

The invention discloses a coring drilling machine for a wood structure in an ancient building wall and a sampling method. The coring drilling machine is provided with a drill body, a spiral drill rod, a rotating head, a locker, a laser distance measuring instrument, a digital display instrument, a laser distance measuring switch, a power driving device, a control switch, a scrap sampling collector, a hollow drill bit, a plurality of elastic telescopic rods, a rotating fixing disc and a drill rod telescopic adjuster. The power driving device is provided with a connecting body fixedly connected with the drill body, a driven gear, a plurality of connecting rods, four small motors, four transmission shafts, four driving gears and four pairs of bearing seats. The drill rod telescopic adjuster is provided with a limiting channel, an ejector rod pushing the spiral drill rod to extend outwards from the limiting channel, a rear spring, an ejector rod switch and an ejector rod buckle. The invention further provides a sampling method for the wood structure in the ancient building wall. Two specifications of a bulk sample and a core-shaped sample can be obtained according to different detection requirements, and both a fragment-shaped sample and a columnar sample are visible samples, so that sampling and observation are convenient, and the machine is economical, practical, convenient and rapid.

Description

technical field [0001] The invention relates to a wooden structure coring drill, in particular to a wooden structure coring drill inside an ancient building wall, which can be used in the field of civil engineering, especially ancient building engineering. The invention also relates to a sampling method for wooden structures inside ancient building walls. Background technique [0002] Existing samplers can only take (taking refers to sampling, sampling) debris-like samples of wood components, and it is inconvenient to disassemble. After sampling, the sample holder needs to be replaced, and the sampling status cannot be observed at any time. It is better to detect wood material, decay condition, moisture content and other items. [0003] Related patent documents: CN109025878A discloses a core drilling rig, which includes a power head and a fixing seat that can be fixed inside the roadheader. frame; wherein, the fixed seat is detachably connected to the advancing beam, and t...
