Matching coring device convenient for positioning and coring and easy to clamp coring sample

Abstract

The invention relates to a matching coring device convenient for positioning and coring and easy to clamp a coring sample, which is characterized by comprising an organ cover, an infrared positioningdevice, a fixing fixture and a fixed tray with a card slot, wherein the organ cover covers the outer side of a drill pipe and fixed on the lower end of a bearing; the infrared positioning device is mounted on the contact surface of the drill pipe and the bearing; the fixing fixture comprises a spiral rod-type active abutting plate and a passive abutting plate; and the fixed tray with a card slot is used for adjusting and fixing the directions and positions of the spiral rod-type active abutting plate and the passive abutting plate. Sewage can be prevented from splashing to a worker in the casewhen the drill pipe is cored; in the case of coring, due to infrared positioning assistance, the coring position is accurate; due to a pressure dividing baffle, the cored sample can be protected frombeing damaged; and three concrete slabs can be stacked in layers on three pads for simultaneous coring, and the working efficiency is improved.

Description

technical field [0001] The invention relates to protective measures for a drill-pipe coring machine, relates to the optimization of a fixture of the drill-pipe coring machine, and relates to the optimization of the coring accuracy, and is especially suitable for a matching coring machine which is convenient for positioning and coring and easy to clamp the coring sample. core device. Background technique [0002] The model of drill pipe corer commonly used in the laboratory is ZS-100, which is mainly used to take cylindrical test blocks to study impact and creep properties. However, the above drill pipe coring machine has the following problems: when the drill pipe is coring, it is necessary to open the water valve to allow water to flow out from the drill pipe, open the drill pipe, and the high-speed rotating drill pipe will cause water to splash; The position of coring cannot be accurately determined, and there will be deviations during coring, resulting in waste of materi...

Problems solved by technology

But there is following problem in above-mentioned drilling rod coring machine: when drilling rod coring, need to open water valve, allow water to flow out from drilling rod, open drilling rod, the drilling rod of high-speed rotation can make water splash; The position of coring cannot be accurately determined, and there will be deviations during coring, resulting in waste of materials; when fixing the coring specimen, one end of the fixture is fixed with screws, which will cause stress concentration and damage; when taking a similar concrete slab For test pieces, only one sample can be taken at a time, which is inefficient
