The technical solution of the utility model is,
A kind of rock core adds to be held and stripping assembly, described add to hold comprise adding with stripping assembly and hold unit and removable unit; Described adding, hold the unit and be arranged on rock core 11 1 ends to be measured; And described add to hold arrange porosely in the unit, and screw thread or groove button are set in described hole;
Described removable unit is for picking and placeing bar 12, and at the described diameter that picks and places bar 12 1 ends and described to add the hole internal diameter of holding in the unit adaptive; And be provided with described adding and hold screw thread or the notch that mates in the cell orifice at described bar 12 1 ends that pick and place.
In concrete application, described add hold the unit be rock core pad 9 or the compensation pipe nipple.
To regulate plug 6 and closely cooperate with rock core 11 in order to make, the described hole of holding in the unit that adds is through hole, and namely the hole connects whole adding and holds the unit.
In order to make removable unit hold the unit and closely cooperate with adding, hold the whole inner wall surface of cell via or be provided with screw thread or groove button apart from 1-3cm place, two ends, hole in described adding.
In concrete core holding unit, described adding, hold the unit and be arranged on described rock core 11 1 ends, and by regulating plug 6, active catch wing 7 and control hand wheel 8 are fixed in the core holding unit; And by regulating plug 6, active catch wing 7 and control hand wheel 8 are regulated, and will regulate plug 6 and hold out against described rock core 11.
Described removable unit one end inserts and by screw thread or notch and describedly add that to hold the unit fastening.
The opposite side of described rock core 11 is provided with stop plug 3, and adds at rock core and to hold packing element 5 and packing element plug 2 thereof; Be outside equipped with end cap 1 at described packing element plug 2.
The material of described rock core pad 9 is a kind of in stainless steel, teflon or the organic glass, and the described material that picks and places screw 12 is a kind of in plain carbon steel, tygon or the rubber.
A kind of rock core provided by the utility model adds to be held and stripping assembly, and it picks and places with fetching tool and by realizations such as rotary screwing threads, and is simple in structure, reduces the loaded down with trivial details step that picks and places in the rock core operation, reduces the flow chart difficulty, improves operating efficiency.

Embodiment
Below in conjunction with embodiment, further specify the utility model.
Of the present utility model a kind of rock core as shown in Figure 1 adds a kind of rock core pad 9 of holding with stripping assembly, itself and quick fetching rock core pad combination of the present utility model shown in Figure 3 pick and place bar 12 combinations, as shown in Figure 4, have the hole that connects whole rock core pad 9 in the rock core pad 9 of Fig. 1, described rock core pad 9 mesopores are positioned at rock core pad body center, the inwall in described hole is covered with internal thread or groove button 13, and the external thread that picks and places bar 12 among the internal thread in described hole or groove button 13 and Fig. 3 is complementary.The material of described rock core pad 9 is stainless steel, and the described material that picks and places bar 12 is plain carbon steel.
The concrete steps of the using method of embodiment 1 in core holding unit are as follows:
Assemble as shown in Figure 5, the operation handwheel of hand-held stop plug 3 inserts stop plug 3 in the end cap 1, and the direction of regulating stop plug 3 makes the groove of its boss aligning end cap l also continue stop plug 3 is changed in the groove of end cap l, turn clockwise 90 °, stop plug 3 is in place.From the other end of core holding unit main body 4 rock core 11 of packing into, if rock core is shorter, the rock core pad 9 of packing into simultaneously.Pack into according to the method for the stop plug 3 of packing into subsequently and regulate plug 6 and make active catch wing 7 location, the control hand wheel 8 that turns clockwise holds out against rock core 11 until regulate plug 6, guarantees to be filled in the packing element 5, prevents that packing element 5 is damaged when adding confined pressure, even cracked.If the length of rock core pad 9 is improper, need to change, then to be rotated counterclockwise control hand wheel 8, remove the state that holds out against of regulating between plug 6 and the rock core 11, again active catch wing 7 is rotated counterclockwise 90 °, can takes out regulating plug 6, will pick and place bar 12 and be connected with rock core pad 9, change the rock core pad of appropriate length after taking out, can hold out against rock core 11 until regulate plug 6.
After having tested, confined pressure outside the venting packing element 5, at first be rotated counterclockwise control hand wheel 8, remove the state that holds out against of regulating between plug 6 and the rock core 11, active catch wing 7 being rotated counterclockwise 90 ° can take out regulating plug 6 again, in like manner also can take out stop plug 3, because the two ends of rock core 11 all are in free state, be easy to take out from core holding unit.
Embodiment 2
