Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples as follows：
As shown in Figure 1-Figure 3, rock mechanics tests bearing system under high temperature and pressure multi- scenarios method, including force snesor is lifted
Seat 1 is used to jack the jack 2 that force snesor lifts seat 1 with MTS hydraulic servo platform 5 is supported in；
The force snesor lifts seat 1 and includes the terminal pad 11 being connected with jack 2, is used to support MTS three-axis force biography
The support plate 12 of sensor and operating walk way 13 for carrying out MTS triaxial force sensor dismounting；It is arranged in the terminal pad 11
The groove 111 of oriented lower recess, the support plate 12 is located in groove 111 and free support is in terminal pad 11, and by groove
111 side wall constitutes radial limit to support plate 12；The terminal pad 11 and support plate 12 are the ring that middle part is provided with through-hole
Shape is made of manipulation operating walk way 13 through-hole in terminal pad 11 and support plate 12；And it is provided with for preventing MTS three-axis force from passing
The limiting device of sensor disengaging support plate 12.
The utility model, force snesor lift seat 1 for lifting force snesor, force snesor lift seat 1 be supported in it is very heavy
On top 2, seat 1 is lifted by the jacking force snesor of jack 2 and lifts force snesor to position to be installed, or passes through jack
2, which retract force snesor, lifts seat 1 and removes force snesor from the rigid post in triaxial chamber.
And lift the terminal pad 11 in seat 1 and be connected with jack 2, support plate 12 is used to support MTS triaxial force sensor.
12 free support of support plate is in terminal pad 11, i.e., terminal pad 11 constitutes support plate 12 in lower section and limits, and avoids support plate 12
It falls vertically downwards, still, connector etc. is not provided between support plate 12 and terminal pad 11, the two links together, the two
Between can radially relatively move, can also circumferentially rotate.Due to can be opposite between support plate 12 and terminal pad 11
It is mobile, so that by support plate 12 being set in the groove 111 of terminal pad 11, by the side wall of groove 111 to 12 structure of support plate
It radially limits, avoids support plate 12 from diametrically sliding along terminal pad 11 and be disconnected disk 11, to limit support plate 12
With moving radially for terminal pad 11, but make only its axis rotation of support plate 12 so that rotary support tray 12 can be passed through
