Multifunctional rock mechanical property tester

Abstract

The invention discloses a multifunctional rock mechanical property tester. The tester comprises a base, a vertical beam and a suspension arm, wherein a conveying platform and a test rotation table are arranged on the base in the direction towards the vertical beam in sequence, the vertical beam is fixed at one end of the base, a vertical sliding rail is arranged at the center, and the suspension arm is arranged in the position, opposite to the test rotation table on the base, of the top of the vertical beam; a left cutting device is connected to the vertical sliding rail through a locking device; a right cutting device is arranged in the position, opposite to a rock specimen, of the base; the suspension arm comprises a vertical power source and an upper vertical telescopic shaft; a detachable hook is further arranged at the bottom of the upper vertical telescopic shaft, so that stretching of the rock specimen is achieved; the bottom of the test rotation table is supported by a jack structure. The rock mechanical property tester has longer service life, and can realize functions of uniaxial and biaxial compression and stretching as well as cutting.

Description

technical field [0001] The invention relates to the technical field of rock mechanics test equipment, in particular to a multifunctional rock mechanics characteristic tester. Background technique [0002] Rock uniaxial compression test, biaxial compression test, direct shear test, tensile test and other mechanical property tests are the basic work for the study of rock mechanical properties. At present, a single test equipment can only complete part of the test work. If you want to carry out All the above-mentioned different types of tests need to be completed on test equipment with different functions. Although some existing testers can perform rock uniaxial compression, biaxial compression and tensile tests, it is time-consuming and labor-intensive to replace different test parts when performing different types of tests. In addition, the structural shape of the loading frame of the existing rock mechanical property tester is usually designed as a door frame type or a doub...

Problems solved by technology

Although some existing testers can perform rock uniaxial compression, biaxial compression and tensile tests, it is time-consuming and labor-intensive to replace different test parts when performing different types of tests

In addition, the structural shape of the loading frame of the existing rock mechanical property tester is usually designed as a door frame type or a double-column type or a four-column type. cut function

Furthermore, the loading frame that can realize the shear test is usually a column type loading frame system composed of horizontal columns and vertical columns. This frame structure is relatively complicated, and the frame of the shear testing machine is usually Only shear tests can be done and no other types of tests can be performed

[0003] There are also some rock mechanical performance testing machines that can test different mechanical properties on the same testing machine, realizing the purpose of one machine with multiple functions, but when it is in use, the shear box will break, and it is easy to break when it is stretched by the cantilever , the stretching effect is not ideal
