The specific embodiment
In order to understand the present invention better, below in conjunction with embodiment and accompanying drawing technical scheme of the present invention is done further explanation, referring to Fig. 1 to Fig. 7:
A kind of rock sample core taking fixture by the present invention implements includes platform 6, and platform 6 fixes on the ground through stone bolt 5, and its maintenance is smooth.Circular and irregular core uses circular core clamp assembly and irregular core clamp assembly for clamping, the different shared same platform 6 of anchor clamps of two covers, but do not use simultaneously.
During clamping circle core 1, core stands on the platform 6, adopts the circular core clamp assembly of at least two covers to be uniformly distributed in core surface clamping along the core axis; Circular core clamp assembly comprises annulus 8, jaw components 3, and annulus 8 circumference evenly are provided with three supporting legs 10, and supporting leg 10 offers connecting hole; Column 9 is fixedly connected on the platform 6 after passing connecting hole; Be arranged with sleeve 2 outside the column 9 that adjacent annulus is 8, sleeve 2 external diameters are greater than connecting hole, at column 9 axis direction clamping ringss 8.Annulus 8 sidewalls are provided with and have screwed hole, screwed hole place Connection Card claw assembly 3, and for guaranteeing the steadiness of clamping core, the jaw components 3 of clamping core periphery is set to three covers, along annulus 8 circumference uniform distributions.Jaw components 3 includes claw 12, connecting rod 14, fastening nut 16; Connecting rod 14 cars have screw thread; Be screwed in the annulus 8 and terminally be fixed with claw 12 from screwed hole with sunk screw 13; Connecting rod 14 head ends are combined with fastening nut 16, connecting rod 14 is screwed to rotates fastening nut 16 again after the desired location and make claw 12 push against the outer wall of circular core 1.At fastening nut 16 and 8 of annulus back-up ring 15 is set, back-up ring 15 is welded on annulus 8 sidewalls.
During the irregular rock sample 19 of clamping; Use irregular core clamp assembly, be drilled with equally distributed bolt hole array on the platform 6, irregular core clamp assembly comprises step location-plate 21 and positioning bolt 17; Step location-plate 21 is the L type; Step location-plate 21 bottoms offer locating hole, and pressing plate 18 is stamped in the locating hole top, and positioning bolt 17 connects with the respective threads hole after passing pressing plate 18 and locating hole.In the present embodiment, step location-plate 21 uses four, and four step location-plates 21 clamp the rock side.According to the size and the shape of irregular core, four step location-plates 21 respectively with screwed hole array 22 in respective screw hole connect, the locating hole of step location-plate 21 bottoms is set to slotted hole 23 so that the position of step location-plate 21 is finely tuned.
Implementation process of the present invention is: circular core clamp assembly is support with three columns that are uniformly distributed with 9; Axially assemble sleeve 4, circular core clamp assembly, sleeve 2, circular core clamp assembly and sleeve 11 from bottom to top successively along column 9; The nut at column 9 two is tightened in assembling at last then.Circular core clamp assembly is connected with platform 6 with six bolts that are uniformly distributed with.Put into the circular core 1 of the clamping of wanting; Stand on the platform 6; Tighten three connecting rods 14 of bottom clamping assembly, and fixing with fastening nut 16, guarantee that core is in the center of annulus 8; Claw 12 surperficial crest lines are fully contacted with the core outer round surface, tighten successively more topmost and the connecting rod 14 of middle.
During the irregular rock sample 19 of clamping, circular core clamp assembly is unloaded, rock sample 19 is positioned on the backing plate 20 of platform 6 middle positions, four step location-plates 21 are through pressing plate 18 and bolt and platform 6 corresponding bolts hole matching and fixing, clamping rock side.Round core core and out-of-shape rock that the present invention can the clamping diameter wait keep the stability of each rock sample, so that drill through the rock sample of the dimensions that is applicable to that laboratory research needs.
Above disclosedly be merely preferred embodiment of the present invention, can not limit the present invention's interest field certainly with this, the equivalence of therefore doing according to claim of the present invention changes, and still belongs to protection scope of the present invention.
