Embodiment 1

[0023] Embodiment 1: When performing rock friction angle testing, the drive motor 12 is connected to an external power supply to supply power to the drive motor 12, and the counterclockwise rotation of the drive motor 12 drives the rotating shaft 14 to rotate, and also drives the test piece supporting plate 15 to rotate. While looking at the angle value on the display screen, when the angle value shows 0 degrees, turn off the power switch, put two rock specimens on top of each other and put them on the front end of the specimen supporting plate 15, due to the weight of the rock specimen It may be that the angle value has a certain change, which can be readjusted to 0 degrees through the switch. After the adjustment is completed, the drive motor rotates clockwise by adjusting the switch. The moment the rock specimen slides and falls, turn off the power switch and record the angle value. The test is complete.

Embodiment 2

[0024] Embodiment 2: When carrying out the rock point load test, the driving motor 12, the rotating shaft 14 and the supporting plate in the embodiment 1 are removed, and then a certain pressure is applied by the hydraulic pump to make the piston rod in the jack 2 rise by a certain amount. Connect the centering block 3, the axial displacement transmission plate 4, and the lower pressure head 11 into a whole, and put the groove at the bottom of the centering block 3 on the piston rod of the jack 2, and adjust the linear displacement The probe at the lower part of the sensor 6 is in contact with the axial displacement transmission plate 4, and the crushing receiving plate 10 of the test piece is fixed on the lower pressing head 11 through the round hole in the middle, and then the point load test piece is placed on the upper pressing head 9 and the lower pressing head 9. In the middle of the head 11, apply a little pressure through the oil pump to make the upper pressure head 9 a...

Embodiment 3

[0025] Embodiment 3: Install the axial displacement transmission rod 4 on the rock triaxial test pressure chamber 16 to form a whole, and put the processed cylindrical test piece into the chamber of the rock triaxial test pressure chamber 16 , insert the upper and lower pressure heads, put the rock triaxial test pressure chamber 16 between the jack 2 and the pressure sensor 7, the upper and lower pressure rods are respectively connected to the jack and the pressure sensor 7, and the telescopic probe at the bottom of the linear displacement sensor 6 is adjusted to the The axial displacement transmission rod 4 is in contact. At this time, the hydraulic rod of the jack 2 slowly rises through the slow pressure applied by the oil pump, so that the upper pressure rod in the rock triaxial test pressure chamber 16 contacts the pressure sensor 7 and generates a certain pressure. At this time, a certain confining pressure is applied to the oil reservoir in the rock triaxial test pressure...

Abstract

The invention provides a modular portable rock mechanics parameter tester, which comprises a machine frame, wherein a jack is arranged at the bottom part in the machine frame; a pressure sensor is arranged in the rack and corresponds to the upper part of the jack; one end of the jack is detachably connected with a lower pressing head or a rock triaxial test pressure cabin; a test piece crushing and receiving disc is arranged on the lower pressing head; one end of the pressure sensor is detachably connected with an upper pressing head; a linear displacement sensor is arranged on the machine frame; an axial displacement transmission plate is arranged on the lower pressing head; the side surface of the machine frame is detachably connected with a driving motor, and one end of the driving motor is connected with a horizontal rotating shaft; a test piece supporting plate is detachably connected to the rotating shaft; and an inclination angle sensor is arranged on the test piece supporting plate. The modular portable rock mechanics parameter tester provided by the invention is convenient to operate and can be used for outdoor detection.

Description

technical field [0001] The invention relates to the technical field of rock testing devices, in particular to a modular portable rock mechanics parameter tester. Background technique [0002] Engineering survey is the basic link of the whole project construction. In our country, hundreds of engineering accidents are caused every year due to inadequate preliminary surveys. The large deformation of tunnels and the collapse of railways have brought economic losses, which also threaten the safety of people's lives. In the traditional way, surveyors conduct field surveys , carry out on-site sampling, and bring the rock samples back to the laboratory for data analysis by means of people carrying horses. It can be seen that the characteristics of traditional survey methods are: long cycle and high cost. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a modular portable rock me...
