Technical Field

[0001] The utility model relates to the field of rock triaxial instrument equipment, in particular to a high-temperature and high-pressure rock triaxial instrument. Background Art

[0002] The high-pressure rock triaxial testing system is used to complete triaxial rock experiments based on a large load and high pressure load frame with high precision requirements. In specific applications, some rocks need to be used in high-temperature environments, and the existing rock triaxial testing system cannot perform load detection on rocks in high-temperature environments.

[0003] According to the patent document with the existing publication number CN205103104U, a high-temperature and high-pressure rock triaxial instrument device is disclosed, which includes a test chamber arranged on a frame, in which a rock sample to be tested is placed, and pressure devices are provided on the upper side, front side and left side of the test chamber. The pressure device includes a pressure cylinder arranged on the outside of the test chamber and a pressure plate connected to the pressure cylinder and arranged inside the test chamber, and a heating plate is provided on the pressure plate near the rock sample. When this technical solution is in use, a heating plate is provided on the pressure plate, and a steam generating device capable of filling the test chamber with steam is provided at the bottom of the frame, so that the rock sample in the test chamber can be subjected to a high-pressure load test in a high-temperature environment. At the same time, the control system can control the opening and closing of the heating plates on different pressure plates, and can perform load tests on the rock when different surfaces are heated. Regarding the above technical solution, although this solution realizes high-temperature load testing, it is not convenient to quickly discharge the internal rock after the test, which is inconvenient during use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a high-temperature and high-pressure rock triaxial instrument to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. When in use, the limit seat is pulled out from the inside of the movable seat. After being pulled out, the movable seat loses its limiting force. The movable seat rotates through the rotating column to discharge the rock inside the ring seat to one side, thereby facilitating the later cleaning of the rock inside the ring seat.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a high-temperature and high-pressure rock triaxial instrument, including a triaxial instrument body, the triaxial instrument body including a fixed seat, a support seat fixedly installed on the top of the fixed seat, a mounting seat fixed on the top of the support seat, a hydraulic mechanism fixedly installed on the mounting seat, an extrusion plate fixed at one end of the hydraulic mechanism, a pressure sensor fixedly installed inside the extrusion plate, a lifting mechanism installed on the side of the hydraulic mechanism, the lifting mechanism fixedly installed on the mounting seat, and a movable barrel fixedly installed at one end of the lifting mechanism.

[0006] Furthermore, a heating mechanism is fixedly installed inside the movable barrel, and the extrusion plate is movably installed on the top of the movable barrel.

[0007] Furthermore, a movable seat is movably installed between the fixed seats, a ring seat is fixed on the top of the movable seat, and the ring seat is movably installed on the bottom of the movable barrel.

[0008] Furthermore, a rotating column is rotatably installed on the side of the movable seat, a limiting block is fixed at one end of the rotating column, a limiting groove is opened on the inner wall of the fixed seat, and the limiting block is movably installed inside the limiting groove.

[0009] Furthermore, a limit seat is movably installed at the bottom of the movable seat, a handle is fixed on the side of the limit seat, a sliding groove is opened on the side of the limit seat, a slider is movably installed inside the sliding groove, and one end of the slider is fixed on the fixed seat.

[0010] Furthermore, an installation cavity is opened inside the limiting seat, a pushing mechanism is fixedly installed inside the installation cavity, and one end of the pushing mechanism is matched with the movable seat.

[0011] The beneficial effects of the present invention are as follows: the present invention provides a high-temperature and high-pressure rock triaxial instrument, comprising a fixed seat; a supporting seat; a mounting seat; a hydraulic mechanism; a lifting mechanism; an extrusion plate; a movable barrel; a movable seat; a limit seat; a handle; a mounting cavity; a pushing mechanism; a slide groove; a rotating column; a limit block; a ring seat; a heating mechanism; a slider; and a limit groove.

[0012] 1. This high-temperature and high-pressure rock triaxial instrument, when in use, the limit seat is pulled out from the inside of the movable seat. After being pulled out, the movable seat loses its limiting force. The movable seat rotates through the rotating column to discharge the rock inside the ring seat to one side, thereby facilitating the later cleaning of the rock inside the ring seat.

[0013] 2. This is a high-temperature and high-pressure rock triaxial instrument. The driving mechanism moves upward and then drives the movable seat upward. After the movable seat rises, it matches with the descending extrusion plate and simultaneously completes the extrusion test on the rock inside the ring seat to test the force load of the rock after heating.

[0014] 3. In this high-temperature and high-pressure rock triaxial instrument, the extrusion disk moves to cooperate with the top of the movable barrel to block the top of the movable barrel. After blocking, the high temperature inside the heating barrel is prevented from leaking out, causing the heating speed to be too slow. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 6 The utility model provides a technical solution: a high-temperature and high-pressure rock triaxial instrument, comprising a triaxial instrument body, the triaxial instrument body comprising a fixed seat 1, a support seat 2 is fixedly installed on the top of the fixed seat 1, a mounting seat 3 is fixed on the top of the support seat 2, a hydraulic mechanism 4 is fixedly installed on the mounting seat 3, the hydraulic mechanism 4 is a hydraulic push rod, the hydraulic push rod pushes the extrusion plate 6 to move upward, one end of the hydraulic mechanism 4 is fixed with the extrusion plate 6, a pressure sensor is fixedly installed inside the extrusion plate 6, the pressure sensor is installed at the bottom of the extrusion plate 6, and monitors the pressure applied to the extrusion plate 6, a lifting mechanism 5 is installed on the side of the hydraulic mechanism 4, the lifting mechanism 5 is an electric push rod, the electric push rod pushes the movable barrel 7 up and down, the lifting mechanism 5 is fixedly installed on the mounting seat 3, one end of the lifting mechanism 5 is fixedly installed with the movable barrel 7, a heating mechanism 17 is fixedly installed inside the movable barrel 7, the extrusion plate 6 is movably installed on the top of the movable barrel 7, the heating mechanism 17 is composed of an electric heating wire, and the high temperature generated by energizing the electric heating wire is used to heat the rock.

[0024] In this embodiment, a movable seat 8 is movably installed between the fixed seats 1, and a ring seat 16 is fixed on the top of the movable seat 8, and the ring seat 16 is movably installed on the bottom of the movable barrel 7. A rotating column 14 is rotatably installed on the side of the movable seat 8, and a limiting block 15 is fixed at one end of the rotating column 14. A limiting groove 19 is opened on the inner wall of the fixed seat 1, and the limiting block 15 is movably installed inside the limiting groove 19. A limited seat 9 is movably installed on the bottom of the movable seat 8, and a handle 10 is fixed on the side of the limiting seat 9. A slide groove 13 is opened on the side of the limiting seat 9, and a slider 18 is movably installed inside the slide groove 13. One end of the slider 18 is fixed on the fixed seat 1, and an installation cavity 11 is opened inside the limiting seat 9. A pushing mechanism 12 is fixedly installed inside the installation cavity 11, and one end of the pushing mechanism 12 cooperates with the movable seat 8. The pushing mechanism 12 is an electric push rod. After the electric push rod pushes the movable seat 8 upward, it cooperates with the hydraulic mechanism 4 to achieve bidirectional extrusion of the rock.

[0025] The device provides the required electrical energy to the electrical appliances inside the device through an external power supply. When using the device, the rock to be tested is first placed inside the ring seat 16, and then the lifting mechanism 5 is started to push the movable barrel 7 downward. The movable barrel 7 moves to the side of the ring seat 16, and the movable barrel 7 limits the ring seat 16 while avoiding the influence of the movable seat 8 shaking on the rotating column 14. After the movable barrel 7 descends, the hydraulic mechanism 4 pushes the extrusion plate 6 to enter the top of the movable barrel 7 and seals it. After sealing, the heating mechanism 17 is started to heat the rock inside the ring seat 16. After heating, a temperature sensor is fixedly installed inside the movable barrel 7 to monitor the temperature of the rock in real time and observe the load of the rock under high temperature. After the high-temperature test of the rock, the heated rock can be tested. The rock is subjected to an extrusion test, and an extrusion test can also be performed before the rock is heated. When the rock needs to be extruded, the hydraulic mechanism 4 is started to push the extrusion plate 6 into the interior of the movable barrel 7. The extrusion plate 6 realizes the extrusion of the rock inside the ring seat 16. While extruding, the pushing mechanism 12 pushes the movable seat 8 upward to move upward, providing two-way extrusion for the rock inside the ring seat 16. After the rock is crushed after extrusion, the pressure value borne by the rock is monitored. When the rock inside the ring seat 16 needs to be cleaned, the bottom of the movable seat 8 loses its supporting force after the limit seat 9 is pulled outward, and the movable seat 8 rotates and tilts in the direction opposite to the moving direction of the limit seat 9. After tilting, the movable seat 8 rotates 90 degrees and is limited by the limit seat 9. The rock inside the ring seat 16 is discharged outward, which is convenient for later cleaning.
