Background technology
Core holding unit is widely used in rock core related property testing experiment, is generally required in core test to a large amount of
Rock core does the parameter measurement of each side, and its operating process has complicated property.At present, conventional core holding unit is generally using centre
Cylinder, the mode of both ends plug control space to form sealing, and inner barrel is placed with the packing element of clamping rock core, and packing element is by both ends
Plug positions.At work, rock core control confined pressure is formed by injecting hydraulic oil into the confined space of cylinder and packing element, stifled
Head both ends injection displacing medium simulated formation water, oil etc..Need to remove both ends plug during demolition, installation rock core and use push rod
Release rock core, operation it is excessively cumbersome, long-term use be unfavorable for the seal of device, for this reason, it is necessary to design it is a kind of more efficiently,
Efficiently core holding unit works to complete rock core dependence test so that the demolition, installation work of rock core is more convenient.
The content of the invention
The purpose of this utility model is to solve the above problems, and proposes a kind of easy to use, the rock core folder of efficient work
Holder completes the work of quick demolition, installation to realize in rock core test to the rock core in the range of certain length.
The purpose of this utility model is achieved through the following technical solutions：It is a kind of can quick demolition, installation rock core clamper, it is main
To include left plug, end cap, ring flange, cylinder, right plug, ring flange is connected by screw is placed in two in cylinder both ends, packing element
Coordinate between ring flange and with cone angle at the top of ring flange, via hole, Liang Zhefen are provided with the outside of the big end of end cap and right plug
It is not connected through a screw thread with cylinder both ends ring flange, left plug coordinates with circular hole in the middle part of end cap, and push rod passes through with left plug afterbody
Threaded connection, left plug and right plug and rock core cooperative end part offer air slot, and inside offers medium holes, in packing element
Portion is rock core chamber, and cylinder body bottom offers inlet opening and outage.
Convex is provided with the top of end cap small end, sealing slot cross-section is less than end, is advantageous to the stability of sealing ring；Push rod is cut
Face is that opening is fan-shaped, is easy to pipeline to pass in and out.
The beneficial effects of the utility model are：(1) left plug is built-in expansion with respect to end cap, and tail end can be connected by screw thread
Push rod is connect, internal rock core, simple operation can be ejected by left plug by only needing to remove right plug after completing to test；(2) push rod
Section is that opening is fan-shaped, is easy to pipeline to pass in and out, is attached in the case where not influenceing left plug afterbody pipeline with left plug.
