Electrode clamping device of rock specimen electrical performance tester

Abstract

The invention discloses an electrode clamping device of a rock specimen electrical performance tester. The electrode clamping device comprises at least two support parts, a cross beam, at least two connecting parts and fixing parts, wherein the cross beam is arranged on the support parts; the connecting parts are telescopic connecting rods, anda slider is arranged at one end of each telescopic connecting rod and glidingly connected to the cross beam; the fixing parts are arranged at the other ends of the connecting parts, the connecting parts are clamps used for clamping an electrode of the rock specimen electrical performance tester. The electrode clamping device meets demands of electrical performance test of a rock specimen and can guarantee consistence among multiple electrodes duringelectrical performance testing without artificial holding of the electrode, so that the electrical performance test result is more stable and reliable, and meanwhile, the measurement speed and efficiency are improved.

Description

technical field [0001] The invention relates to an electrode clamping device, in particular to an electrode clamping and stabilizing device for a rock specimen electric property tester. Background technique [0002] The rock specimen electrical tester is used to measure electrical parameters such as resistivity and electrical conductivity of concrete test blocks or stones. The equipment is often taken to deep mountains or construction sites where tunnel railways are opened. At present, when using the rock specimen measuring instrument for four-electrode measurement, the contact of the electrodes is usually measured by holding four electrodes. During the process of holding by two people with four hands, the hand-held measurement is due to the difference in the size of the contact point and the downward vertical use force. As well as the difference in contact integrity, it will have a great influence on the measurement results. [0003] The existing electrode clamping device ...

Problems solved by technology

At present, when using the rock specimen measuring instrument for four-electrode measurement, the contact of the electrodes is usually measured by holding four electrodes. During the process of holding by two people with four hands, the hand-held measurement is due to the difference in the size of the contact point and the downward vertical use force. and the difference in contact integrity will have a great influence on the measurement results

[0003] The existing electrode clamping device in the field of metallurgy has complex structure and cumbersome operation

The equipment used for electrical testing of rock specimens needs to be taken to the field for measurement frequently, and the corresponding electrode holding device also needs to be carried to the site, so the requirements for wear resistance and durability are high

However, this field lacks an electrode holding device with strong applicability and easy operation. Therefore, it is necessary to study a suitable electrode holding device to fill the gap in this field.
