Detailed Description
The invention will be further explained with reference to the drawings:
referring to fig. 1, 2, 3 and 4, the rock core clamping device for simulating the formation inclination angle includes an outer sleeve 1, a manual lifting platform 2, a base 4, a fixing clip 3 and a track 6, wherein the outer sleeve 1 is a cuboid with a hollow opening on one side, the base 4 is a cuboid platform, the fixing clip 3 and the track 6 are welded on the upper end surface of the base 4, the lower end of the manual lifting platform 2 is inserted into the fixing clip 3, the upper end of the manual lifting platform 2 is inserted into a clamping groove 10 of the outer sleeve 1, and an arc groove 7 at the lower end of the outer sleeve 1 falls on the track 6 of the base 4. The bottom surface of the outer sleeve 1 is provided with an ejection threaded hole 8, the side surface of the outer sleeve 1 provided with the clamping groove is provided with two fixed threaded holes 9, the artificial rock core is placed into the outer sleeve 1, the screw is screwed up through the fixed threaded holes 9 on the side surface of the outer sleeve 1, the rock core can be fixed, the effect of reinforcing the rock core is achieved, and the bearing capacity of the rock core is increased. When the stratum inclination angle needs to be simulated, the manual lifter 2 is slowly shaken, the outer sleeve 1 can stretch out and draw back to different heights, and different stratum inclination angles required by the experiment are simulated, so that the experiment is carried out. When dismantling artificial rock core, slowly become flexible the screw of 1 lateral part of outer sleeve to make fixed rock core not hard up, a screw is injected to the ejecting screw hole 8 of rethread outer sleeve bottom surface, screws up the screw, slowly ejecting the rock core through the extension of screw, thereby takes out the rock core. A guide angle of 45 degrees is arranged above the screw.
