Description
Technical field
The present invention relates to a kind of ice core borehole opening protection device, in rig running, can prevent implements from falling into ice
Core drilling internal congestion ice core borehole, damage even stuck ice core rig, ensure that ice core drills through being smoothed out for work.
Background technology
Ice core borehole is continuously to drill through more piece ice core vertically downward from superglacial using ice core rig and lift ice core
The hole formed after to ground, ice core borehole extend to subglacial basement rock from the ice core borehole opening of superglacial.
When drilling through ice core, ice core rig is opened by the ice core rig bracket positioned at ice core borehole top and cable multipass ice core borehole
Mouth declines and lifted to drill through and extract ice core, and because exposed ice core borehole opening is parallel to the ground, staff takes with oneself
Instrument, utensil and other articles such as implements such as screwdriver, gloves, marking pen of band are inadvertently fallen off, and are slipped into ice core from ground and are bored
Hole.Due to ice core borehole diameter very little and depth is very deep, it is difficult to which implements are taken out from hole, causes the obstruction of ice core borehole, hard
Hard implements may damage the cutter head of ice core rig, cause ice core rig not to be drilled down into；Another aspect ice core rig also can
Blocked by implements, make ice core rig is stuck can not be proposed in drilling, can only finally abandon ice core rig, cause the Zhi Bingxin to bore
Take the failure of work, it has to select suitable ice core to drill through and a little drill through ice core again, cause the significant wastage of manpower and materials.
The content of the invention
In view of it is above-mentioned, it is an object of the invention to provide a kind of ice core borehole opening protection device, for preventing implements from falling
Enter in ice core borehole.
The object of the present invention is achieved like this：
A kind of ice core borehole opening protection device, is made up of frid, steel ring, block and drill rod, frid be surrounding edge bending to
Under, rectangular box like structure, it is buckled in above ice core borehole.There is hole frid corner, and frid is fixed on ground by drill rod by hole；Steel
Circle is consolidated in the center of frid, and relative with the center of drilling, and block is covered with steel ring, and block center is provided with hole and otch, bores
When taking ice core, the cable being connected with drill bit is placed in hole by otch.
Advantages of the present invention and caused beneficial effect are：
1st, frid of the invention is rectangular box-shaped structure, and box mouth can be buckled in above ice core borehole downwards, and the trough rim of frid can cut into
Superglacial, four fixed drill rods so can effectively prevent rotation, the slip of frid in the horizontal direction from Corner Strapped frid
With the movement in vertical direction so that the present invention keeps fixing with ice core borehole opening relative position, and steel ring is located in frid
The heart, one is consolidated in frid, the center of steel ring is relative with the center to drill, is easy to ice core rig to pass in and out ice core borehole, improves
Ice core drills through the efficiency of work.
2nd, the bore of steel ring is 150 mm on frid of the present invention, more than the mm of ice core borehole diameter 95；The bore 170 of block
Mm is more than the bore of steel ring again, covers on steel ring, prevents block from freezing with steel ring, facilitates the quick of block to cover and remove, keeps away
Exempt to collide with steel ring when ice core rig frequently passes in and out ice core borehole；Block cable through-hole diameter is more than cable size, this sample prescription
Just cable walking in block hole, the friction of cable and block hole hole wall is reduced；Steel ring is erect, and can prevent the ground implements that drop
Slide into ice core borehole；The cable being connected with drill bit is placed in cable through-hole by the otch of block, carries out drilling through and proposing for ice core
Take work.
3rd, the present invention is simple in construction, reasonable in design, can effectively avoid during ice core drills through, implements fall into ice core borehole
It is interior, phenomena such as ice core borehole blocks, ice core rig damages and be stuck occurs, ensures that ice core drills through being smoothed out for work, reduces
The waste of manpower and materials.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
The ice core rig that the present invention uses is aims at the light rig designed under high mountain extreme condition（Model：BZXJ-Ⅱ
D）, the drilling cramp height of the light rig：~ 3 m, bit weight：21 kg, bore bucket length：1.75 m, drill through ice core diameter：94-95
Mm, single drill through ice core length：0.7-0.8 m, power of motor：0.3 kW, mains power：220 V, 2 kW exchange gasoline generate electricity
Mechanical, electrical cable（Model：4H-181A）Length:300 m, cable size（4.72 mm）, bore deep degree：200-250 m.Rig connects
It is as follows to connect mode：Cable is connected after winch extraction by the pulley on drilling cramp with drill bit, and ice core bores bucket and is stuck in chisel edge,
Cutter head, which is arranged on, bores bucket front end, and so whole ice core rig is by cable vertical lifting under drilling cramp.
Technical scheme is described further with reference to the accompanying drawings and examples：
As shown in figure 1, a kind of ice core borehole opening protection device, is made up of frid 1, steel ring 2, block 3 and drill rod 4.Steel ring 2
Bore is 150 mm, more than the mm of ice core borehole diameter 95；The bore of block 3 is 170 mm；Frid 1 is that surrounding edge is downward
Hem with invisible stitches, rectangular box like structure, be buckled in above ice core borehole.1 four jiaos of frid has a hole, and the mm drill rods 4 of length 300 pass through 1 four jiaos of frid
Hole frid 1 is fixed on to the snow of superglacial（Ice）Layer；High 35 mm of steel ring wall, is consolidated in the center of frid 1, and with drilling 5
Center it is relative, block 3 is covered with steel ring 2, the center of block 3 is provided with hole 8 and otch 7, wide 5.5 mm of otch；Hole 8 it is a diameter of
7.5 mm；In drilling 5, the cable 6 being connected with drill bit is placed in hole 8 by otch 7.
During work, after first ice core drills through, the opening of 95 mm ice core borehole 5 is formed, and lifting ice core rig is extremely
Superglacial is simultaneously removed from the opening of ice core borehole 5.The box mouth of frid 1 is first buckled in the glacier table of the opening of ice core borehole 5 down
Face, and allow the center of ice core borehole 5 and the center alignment of steel ring 2, then frid 1 is pressed down on hand, makes the surrounding of frid 1
Trough rim from superglacial cut, until the bottom of frid 1 contacts with superglacial；Frid 1 is each passed through by 4 drill rods 4
Frid 1 is fixed on superglacial by the hole of corner, and taps fixed drill rod 4 downwards with iron hammer, until drill rod 4 gos deep into glacier completely
It is internal.After frid 1 fixes, block 3 is buckled on steel ring 2, completes the protection of ice core borehole opening.When continuation ice core drills through,
Move block 3 away, expose ice core borehole 5, ice core rig vertically declines in the presence of cable, and enters ice core by steel ring 2 and bore
In hole 5, cable 6 is then allowed to be moved on to by the otch 7 in block 3 in the hole 8 of block 3, block 3 covers steel ring 2, continues to fall ice
Core rig to the bottom of ice core borehole 5 carries out drilling through and extracting for ice core.Ice core borehole 5 is finished and is promoted to when a section ice core drills through
During opening, block 3 is removed from steel ring 2, then cable 6 is removed from hole 8 and otch 7, continues to lift up ice core rig extremely
The top of ice core borehole 5, cover steel ring 2 with block 3 immediately, to protect the opening of ice core borehole 5, avoid implements drop ground cunning
Enter ice core borehole.
