Description
Technical field
The utility model relates to a kind of diametral compression test device, particularly relates to a kind of diametral compression test device being applicable to right cylinder and cube coal petrography sample.
Background technology
Diametral compression test is one of basic mechanical experiment of coal petrography, has usually been come by coal petrography diametral compression test device.Existing coal petrography diametral compression test device comprises base, steel wire is provided with on base, put coal petrography sample, steel wire and backing plate successively again, the nut eventually passing the right and left is fixed, opening pressure testing machine, along with pressure testing machine loading gradually, first can with pad contact above, and it is compressed, the distance between base and backing plate can be reduced, thus cause coal petrography sample substantially along the direction cracking that steel wire is placed.
In above-mentioned coal petrography sample cleaving process; because coal petrography sample and pressurized backing plate above are not fixed; in pressure testing machine compression process; coal petrography sample and backing plate can produce slip; therefore; in this experimentation, need one to two people to be fixed backing plate above and coal petrography sample with hand always; consume a large amount of manpowers and time; and due to artificial factor; the result of experiment neither be reliable especially; frequent meeting well cannot be fixed it because the long personnel of causing of experimental period are tired, causes splitting poor effect.
Utility model content
The purpose of this utility model aims to provide a kind of easy to operate, coal petrography diametral compression test device that reliability is high.
The utility model is by the following technical solutions:
A kind of coal petrography diametral compression test device, comprise the backing plate above base and base, base top surface is provided with spacing hole, and backing plate bottom surface is provided with the fixed leg corresponding with spacing hole, and backing plate is inserted in the spacing hole of base by fixed leg; Described backing plate bottom surface is provided with locating piece, and base is provided with the lower locating piece corresponding with upper locating piece, and upper locating piece is provided with relative thimble with lower locating piece.
Described base is provided with the fixed mechanism being positioned at lower locating piece outside, and fixed mechanism comprises the arc on the base plate of lower locating piece both sides and base plate, and two arcs are oppositely arranged.
Described base is provided with the fixed mechanism being positioned at lower locating piece outside, and fixed mechanism comprises the flat board on the base plate of lower locating piece both sides and base plate, and two flat boards are oppositely arranged.
The cross section of described upper locating piece and lower locating piece is triangle.
Be provided with cushion block between described base and backing plate, base both sides are provided with the parcel tray adapted with cushion block.
Described base takes the shape of the letter U channel-shaped.
The beneficial effects of the utility model are:
(1) coal petrography sample is placed in the middle of base, removes cushion block, backing plate decline and with coal petrography sample contacts, opening pressure testing machine just can carry out diametral compression test, and structure is simple, easy to operate, improves test efficiency;
(2) fixed leg is reliable with coordinating of spacing hole, avoids backing plate movement in the horizontal direction, can improve precision and the fiduciary level of experiment well;
(3) fixed mechanism be oppositely arranged and with the upper locating piece of thimble, lower locating piece, fixing reliable, split-position is accurate, makes test figure reliability high.
Accompanying drawing explanation
