Abstract
The utility model discloses a novel experiment device for static intrusion of a pressure head to rocks, which comprises an upper plate, a lower plate and vertical posts, wherein the upper plate is mounted on the upper end of a vertical post; the lower plate is mounted on the lower end of the vertical post; a bearing plate is arranged between the upper plate and the lower plate; the bearing plate is connected with the vertical post in a sliding manner; a two-way hydraulic cylinder is arranged on the lower plate; a sliding rail is arranged on the bearing plate; and the sliding rail is sleeved on the vertical post. According to the utility model, the novel experiment device has the advantages that the size of tested block is amplified by 4 to 5 times because of a larger distance between the vertical posts; the maximum experiment force is enhanced to 50 times so as to completely satisfy experiment requires; a sliding rail system is added with or reduced by a steel base plate so as to satisfy demands of experiment blocks in different sizes; application of a two-way oil hydraulic cylinder is used for manually regulating the height of the bearing plate upwards to downwards; the maximum testing force is up to 1000 k N by the loading process of a manual hydraulic pump; and the space of the experiment operation is increased to process a static intrusion experiment on cubic rock samples with larger sizes of 250 mm in lengths, widths and heights so as to satisfy an intrusion experiment for larger rock samples.
Description
Technical field
The utility model relates to a kind of pressure head static(al) and invades the rock test unit, can invade the rock stone and press test.
Background technology
Before constructing tunnel, petroleum drilling, mining, analyze rock mechanics properties, and with regard to fractured rock, rock be pressed into the strength ratio uniaxial compressive strength more near actual conditions.At present; Invade the rock test unit about the pressure head static(al) and be mainly used in hardness and the coefficient of plasticity of measuring rock, maximum test force is less, is generally 10KN-20KN; It is less to test used rock sample, is generally the right cylinder of 50mm height, diameter 50m or the cube of 50 * 50 * 50mm.When the cube rock sample to 200 * 200 * 150mm carried out static(al) intrusion test, maximum test force was obviously not enough.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency provides a kind of novel pressure head static(al) to invade the rock test unit, can invade the large-size test block and press test.
The technical scheme that above-mentioned technical matters adopted that the utility model will solve is:
A kind of novel pressure head is invaded the rock test unit, comprises upper plate, lower plate and column, and upper plate is installed in the column upper end; Lower plate is installed in column lower end; Between upper plate and lower plate, be provided with bearing plate, bearing plate and column are slidingly connected, and lower plate is provided with two-way hydraulic cylinder.
Above-mentioned novel pressure head is invaded the rock test unit, and said bearing plate is provided with slide rail, and slide rail is enclosed within on the column.
Above-mentioned novel pressure head is invaded the rock test unit, is connected with hydraulic hand-pump at the oil-in place of two-way hydraulic cylinder.
Four root posts are fixed upper plate and lower plate through swivel nut, and bearing plate is formed slide rail through four sleeves that are enclosed within on the column, can between upper plate and lower plate, slide up and down.Upper plate leaves the pressure head draw-in groove, can pressure head be fixed on the upper plate with multi-purpose adhesive.Lower plate leaves four screws, can hydraulic cylinder be fixed on the lower plate.
Adopt technique scheme, the advantage of the utility model is following: because the spacing between the column is bigger, can make the test block size enlarge 4-5 doubly.Maximum test force improves 50 times, can satisfy testing requirements fully.Can on slide type rail system, add or reduce billet, to satisfy the requirement of various sizes test block.Adopt two-way oil hydraulic cylinder, manual adjustments bearing plate height loads through hydraulic hand-pump up or down; Maximum test force can reach 1000KN; The test operation space is strengthened, can be to the cube rock sample of large-size, length < 250mm; Carry out static(al) and invade test, satisfy big rock sample and invade test.Adopt two-way oil hydraulic cylinder, height that can the flexible bearing plate loads and adopts hydraulic hand-pump to realize the load test to rock sample, and is simple in structure, easy to operate.
