Pull-up steel wire rope (1) afterwards, the steel wire rope (1) being connected between bracing frame (21) and upper frame (7) is tightened up,
Then bracing frame (21) is upper moves, and now supporting spring (11) gradually becomes level, supporting spring by outer low and inner high
(11) active force gradually becomes thrust downwardly and outwardly by original pulling force inside upwards, then supports
Handss (14) gradually open, after supporting handss (14) to withstand the borehole wall, due to supporting handss (14) and the borehole wall
Between frictional force effect, make that support handss (14) are no longer upper to be moved, bracing frame (21) also cannot be in stake
In hole, upper shifting, continues to pull up steel wire rope (1), in the work of bracing frame (21) and the steel wire rope of upper frame (7)
With under, force upper frame (7) to produce huge lower pressure, upper frame (7) passes through pressure column (16) and pushes up downwards
Pressure drill bit frame (24), force taper bit (27) to be downwardly in the native stone of bottom hole, meanwhile, with prop up
Support (21) passes through drill bit folding drawstring (22) with respect to the upper shifting of pressure column (16), bracing frame (21)
Pull taper bit (27) gradually close, native stone is caught, now supporting spring (11) gradually become interior low
Outer height, supporting spring (11) produces pulling force inside downwards, so supporting handss (14) place diameter gradually to subtract
Little, the diameter until supporting handss to be located is less than bored aperture, makes bracing frame (21) leave the borehole wall, now
Steel wire rope (1) is carried on continuation, outside equipment is proposed stake holes together with the native stone that taper bit (27) is grabbed,
The extension entering above until unloading extension neck (3) unloads device (prior art, in figure is not drawn into), unloads extension disk (2)
Unloaded device by extension to hook, then decentralization steel wire rope (1), the steel wire between upper frame (7) and bracing frame (21)
Rope (1) becomes slack, in taper bit (27), bracing frame (21), support arm (15) and support handss (14)
And under the action of gravity of drill bit assembly, bracing frame (21) glides in pressure column (16) appearance, drill bit is opened
Close drawstring (22) gradually to relax, taper bit (27) opens under gravity, discharge grabbed native stone,
Until bracing frame (21) reaches or close to disk (31)；Drill bit frame (24) reaches or under simultaneously
The latch (30) at end, the space between disk (31) and push rod (29) be enough to accommodate hook (28)
Hook portion, continues to loosen steel wire rope, and the outer rim of disk (31) withstands the lower end inclined-plane of hook (28), makes extension
Hook (28) is flared out and continues to move down until that hook (28) hooks disk (31).Then go up
Carry steel wire rope (1), because drill bit frame (24) is still within the lower end of pressure column (16), so push rod (29)
It is not in contact with linking up with (28), hook (28) continues holding and hooks disk (31).Steel wire rope is carried on continuation
(1), in the presence of hook (28), steel wire rope (1) is tightened, but bracing frame (21) will not be to
Upper slip, equipment is above carried, and until unloading extension disk (2), upper top hangs the self-lock switch unloading in device again, hangs and unloads device
Automatically decontrol and unload extension disk (2), then decentralization steel wire rope (1), equipment is again introduced into stake holes, continues next
The work of circulation.
