For convenience of assembling and maintenance, to guarantee after the second lower sealing ring 12 and the first lower sealing ring 13 surface abrasion still simultaneously
Holding closely cooperates, and as shown in figs. 1 and 12, fixed installation regulation set 16 in described trocar sheath 20, regulation set 16 is positioned at core pipe 8
Periphery, is provided with locating ring 37 inside regulation set 16, and locating ring 37 is positioned at above the first lower sealing ring fixed cover 38, the first lower seal
Ring fixed cover 38 is movably installed in core pipe 8 periphery, and the first lower sealing ring fixed cover 38 energy core pipe 8 relatively is vertically movable, first time
At least offer three the second spring eyes 40 on sealing ring fixed cover 38 upper surface, each in each second spring eye 40 install one the
Two springs 15, the second spring 15 coordinates with locating ring 37 provides downforce for the first lower sealing ring fixed cover 38, it is ensured that first time
Sealing ring 13 and the second lower sealing ring 12 coordinate closely.Second spring eye 40 should be uniformly distributed as far as possible so that the first lower sealing ring is solid
Surely 38 uniform force are overlapped.Installing the second alignment pin 17 between first lower sealing ring fixed cover 38 and locating ring 37, locating ring 37 leads to
Crossing the second alignment pin 17 drives the first lower sealing ring fixed cover 38 to rotate, and prevents the second lower sealing ring 12 at the first lower seal simultaneously
Rotate under the drive of ring 13.For realizing the most accurately handling further, described regulation set 16 is threadeded with trocar sheath 20.First
It is provided with the first sealing ring 3 between lower sealing ring fixed cover 38 and regulation set 16.
Due to described sealer can be profound down to underground with drilling rod position, and depths hydraulic pressure is higher, therefore, for further
Prevent the second upper sealing ring 25 and the first upper sealing ring 26 not tight at hydraulic pressure effect lower seal, design below scheme: such as Figure 11 institute
Showing, the inner surface of described first upper sealing ring fixed cover the 1, second upper sealing ring 25 and the first upper sealing ring 26 is coplanar.Same
Reason, the periphery of described first lower sealing ring fixed cover 38 is provided with the first balance ring 42, outside the second lower sealing ring fixed cover 39
Being provided with the second balance ring 43 week, the difference of the first balance ring 42 internal-and external diameter is equal to the difference of the second balance ring 43 internal-and external diameter.Regulation set 16
Bottom be provided with sheath 41, sheath 41 is positioned at the first balance ring 42 and the second balance ring 43 periphery, and sheath 41 balances ring with first
42 and second balance composition annular chamber 44 between ring 43, both can ensure that hydraulic balance, and can prevent again the solid dirt heap in mud
Amass and affect pressure balance in annular chamber 44.The hydraulic balance of the second lower sealing ring 12 and the first lower sealing ring about 13 both sides can
Improve sealing effectiveness further so that this rig depth drill expands the serviceability of end face of cylinder rotating seal not because of underwater penetration
Strengthen and reduce.Convenient rotation regulates set 16, as shown in figure 12, the sidewall of sheath 41 is offered installing hole 14, passes through installing hole
Insert reinforcing bar in 14 or handle can conveniently rotate sheath 41.
As shown in figure 12, the upper end of described first balance ring 42 is inclined-plane, in order to blowdown in annular chamber 44.
As shown in figure 12, the internal diameter of described second lower sealing ring 12 and the first lower sealing ring 13 is more than the external diameter of core pipe 8, core
Oil extraction dirt chamber 45 is constituted, on the second lower sealing ring fixed cover 39 between pipe 8 and the second lower sealing ring 12 and the first lower sealing ring 13
Offering drain oil 11, drain oil 11 communicates with oil extraction dirt chamber 45, it is simple to oil extraction is dirty and changes new oil.
As it is shown in figure 1, the periphery fixed installation of described core pipe 8 upwards supports the spacing torr of the second lower sealing ring fixed cover 39
Ring 9, spacing filler ring 9 is connected with the second lower sealing ring fixed cover 39 by the first alignment pin 10, the second lower sealing ring fixed cover 39
It is connected by spacing filler ring 9 is fixing with core pipe 8.This design can conveniently be installed and overhaul.
Power and energy is expanded for realizing boring, as it is shown in figure 1, install one-way rotation mechanism between described core pipe 8 and trocar sheath 20,
One-way rotation mechanism makes trocar sheath 20 be only capable of driving core pipe 8 to rotate to a direction.Due on the second upper sealing ring 25 and first
Excellent sealing effect between sealing ring 26 and the second lower sealing ring 12 and the first lower sealing ring 13, single described in whole work process
To rotating mechanism all in closing space, will not be affected by extraneous water or mud.
As shown in Fig. 1, described one-way rotation mechanism can be connected and composed by pawl seat 21, upper ratchet 22 and bottom ratchet wheel 23.
Pawl seat 21 is fixing with trocar sheath 20 to be connected；Pawl seat 21 bottom is provided with vertical slot, and the periphery activity of core pipe 8 is installed
Upper ratchet 22, upper ratchet 22 top is provided with inserted block 28；The inserted block 28 of upper ratchet 22 coordinates with the slot of pawl seat 21, makes
Upper ratchet 22 is only capable of relative pawl seat 21 and pumps.Upper ratchet 22 bottom is provided with lower ratchet 18, bottom ratchet wheel 23
Top is provided with ratchet 19, and lower ratchet 18 and upper ratchet 19 coordinate, and upper ratchet 22 is only capable of driving bottom ratchet wheel 23 to a side
To rotation.Bottom ratchet wheel 23 is fixing with core pipe 8 to be connected.When holing, lower ratchet 18 and upper ratchet 19 are engaged, trocar sheath 20
Core pipe 8 can be driven to rotate, and core pipe 8 alternatively referred to as drill bit connecting rod；When needing capstan, trocar sheath 20 cannot be by upper spine
Wheel 22 drive bottom ratchet wheel 23 rotates, and therefore, the relative ground static of core pipe 8, core pipe 8 rotates relative to trocar sheath 20, this process
On in, ratchet 22 moves back and forth up and down all the time.Described one-way rotation mechanism can also be to be connected and composed by ratchet and pawl, tool
Body structure is as follows: ratchet is installed in the periphery of core pipe 8, and trocar sheath 20 inwall installs ratchet, only when trocar sheath 20 rotates forward, and can
Core pipe 8 is driven to rotate by pawl-and-gearing.But, through great many of experiments repeatedly understand, by pawl seat 21, upper ratchet 22 and under
The one-way rotation mechanism that ratchet 23 is constituted, compared with the one-way rotation mechanism of other structures, has that weight-bearing load ability is strong, work
Stablize and the advantage of length in service life, therefore, be more suitable for equipment on rotation expansion machine and use.
The technical solution of the utility model is not restricted in the range of embodiment described in the utility model.
