A water-saving automatic adjustment device for making cylindrical samples of rock or concrete

Abstract

The invention discloses a water-saving automatic adjustment rock or concrete cylinder sample making device, which comprises a first oil cylinder, a second oil cylinder and a horizontal guide rail, and the first oil cylinder is vertically fixed on the horizontal guide rail by its cylinder barrel The second oil cylinder is horizontally arranged on the other end of the horizontal guide rail by its cylinder barrel, and the first oil cylinder installed vertically can adjust the size of the installation space of the sample, and then can make samples of any height according to needs; The pressure plate and rubber plate are used to install the sample, the sample is driven by a coaxial motor, and the grinding changes from passive to active. At the same time, there is also a grinding assembly driven by the second oil cylinder that can slide left and right. According to the distance between the grinding assembly and the center of the sample, cylindrical samples of different diameters can be produced. At the same time, it is equipped with a control system that can be accurately and automatically supported. seat; the cooling water pipe slides with the vertical slider, saving water and energy; the invention has a simple structure and can complete the production of cylindrical samples at one time, saving time, labor and effort.

Description

technical field [0001] The invention relates to the field of geotechnical engineering instruments, which belongs to a sample making tool, in particular to a water-saving automatic adjustment rock or concrete cylindrical sample making device. Background technique [0002] Existing laboratory rock or concrete sampling machines can only take samples with fixed diameter and limited length. Sampling cannot be achieved if the length of the sample taken exceeds the maximum limit or the diameter of the sample is not the caliber of the existing tool. [0003] Furthermore, in the existing laboratory rock or concrete sampling machines, during the sampling process, with the increase of the drilling depth, the drill pipe tends to swing a little from side to side, which will directly cause the side of the cylindrical sample taken out to be rough. , Sometimes there will be a large dislocation phenomenon, resulting in sampling failure, and the subsequent sample work cannot be carried out, ...

Sampling cannot be achieved if the length of the sample taken exceeds the maximum limit or the diameter of the sample is not the caliber of the existing tool

[0003] Furthermore, in the existing laboratory rock or concrete sampling machines, during the sampling process, with the increase of the drilling depth, the drill pipe tends to swing a little from side to side, which will directly cause the side of the cylindrical sample taken out to be rough. , and sometimes there will be a large dislocation phenomenon, resulting in sampling failure, unable to be used for subsequent sample work, time-consuming, laborious and laborious

[0004] In addition, in the process of drilling and sampling, if there are cracks or joints in the rock, when the tool rotates at high speed, the specimen is easily broken at the joints, which will also lead to sampling failure

[0005] If the height of the required cylindrical sample is less than the depth of the drilling sampler, sometimes it is difficult to grasp the depth of the drilling tool. time

[0006] In addition, the existing stone grinding machine needs to continuously spray water to cool the entire grinding disc surface during grinding, which seriously wastes water resources
