Embodiment person of ordinary skill in the field understood.
As depicted in figs. 1 and 2, the invention provides a kind of native storehouse sealing device of novel shield machine, the shield on the right side of native storehouse
The first mounting groove 2 is offered on the right side of body 1, the bottom land of first mounting groove 2 offers the mounting hole 3 connected with Tu Cang,
The native storehouse sealing device includes connecting shaft 4, and the connecting shaft 4 is located in the mounting hole 3, and the native storehouse sealing device is also
Including sealing ring 6 and retainer ring 5, the sealing ring 6 and retainer ring 5 are arranged in order are placed in the first mounting groove 2 simultaneously from left to right
It is set in the connecting shaft 4；The retainer ring 5 is fixedly installed in shield body 1；The left surface of the sealing ring 6 and described the
The bottom land of one mounting groove 2 is tightly connected, and the inwall of the sealing ring 6 and the outer wall of the connecting shaft 4 are tightly connected；The sealing
Ring 6 and the gap of the first mounting groove 2 coordinate, and the sealing ring 6 can be moved radially in first mounting groove 2.
When shield machine works, cutterhead 7, which is rotated, carries out cutting driving, and cutterhead 7 drives connecting shaft 4 to rotate, when connecting shaft 4 is deposited
When certain rich degree deformation either teetertotters or when cutterhead 7 center of rotation and the first mounting groove 2 center not
When with one heart, the periphery that sealing ring 6 is set in connecting shaft 4 moves radially to follow connecting shaft 4 with the rotation of connecting shaft 4
Surface position and keep sealing state, have certain gap between the mounting groove 2 of sealing ring 6 and first, sealing ring 6 is just herein
The adjustment position of connecting shaft 4 is followed in gap.
Sealing ring 6 will not be rotated with connecting shaft 4, be rotary dynamic seal between connecting shaft 4 and sealing ring 6, because sealing
Ring 6 can be with the adjustment position of connecting shaft 4, therefore such rotary dynamic seal is reliable, the left surface of the sealing ring 6 and institute
State the speed of relative motion between the bottom land of the first mounting groove 2 and apart from smaller, belong to half static seal, such half is quiet close
The effect of envelope is also reliable.
The quantity of the retainer ring 5 is more than two, and the retainer ring 5 is arranged in order and is set in from left to right vertically

Mouthfuls 13 and the wall contacts of the connecting shaft 4 simultaneously keep sealing, second lip 14 and corresponding first mounting groove 2 or the
The bottom land of two mounting grooves 8 contacts and keeps sealing.
Sealing ring 6 is combined by the skeleton 11 and sealing ring 12 of annular, and the sealing ring 6 of this structure is simple in construction simultaneously
And lighter weight, excessive because of self gravitation sealing ring 6 will not be caused to hang in connecting shaft 4 when being set in connecting shaft 4,
On the one hand it ensure that the effect of sealing and reliable and stable, on the other hand avoid abnormal contact to each other, prevent sealing ring 6 and even
The occlusion of spindle 4 ultimately results in shield machine failure.
Dust cap 15 is provided with the right of the sealing ring 6, the dust cap 15 is set in connecting shaft 4 and and described
Retainer ring 5 is fixedly connected, and rotation stop pin 10 is fixedly installed on the left side of the dust cap 15, it is left that the rotation stop pin 10 stretches into it
Simultaneously the sealing ring 6 can be limited in the rotation stop groove 9 of side adjacent seals ring 6 to rotate, the sealing ring 6 can be along the rotation stop groove 9
Length direction is moved；Dust ring 16, the lip of the dust ring 16 and the company are provided with the inner hole wall of the dust cap 15
The wall contacts of spindle 4 simultaneously keep sealing.
Dust cap 15 is arranged on the right side of sealing ring 6, and the effect of axial limiting is on the one hand served to sealing ring 6, another
Aspect serves the effect of auxiliary seal to the sealing ring 6 in left side, the reliability of Tu Cang sealings is further enhancing, while also having
Certain external world's dustproof effect, prevent that environmental contaminants from entering in sealing ring 6 sealing state for destroying sealing ring 6, it is to avoid slag
The situation of soil leakage.
Between two adjacent retainer rings 5, between shield body 1 and leftmost side retainer ring 5 and dust cap 15 and the rightmost side
Auxiliary seal ring 17 is provided between retainer ring 5, when the bottom land sealing of the left surface of sealing ring 6 and the first mounting groove 2 in left side
During Joint failure, dregs is entered between the mounting groove 2 of sealing ring 6 and first or the second mounting groove 8, and auxiliary seal ring 17 can be sealed
The dregs firmly leaked outside, dregs by right side sealing ring 6 the first lip 13 and the second lip 14 sealed, will be improved with this
The reliability of multiple-sealed barrier.
Greasing oil duct 18 is provided with the retainer ring 5；Described one end of greasing oil duct 18 connects the greasing pipe of shield machine, separately
The inner chamber of adjacent second mounting groove 8 in inner chamber or left side of adjacent first mounting groove 2 in the left side of one end connection correspondence sealing ring 6.
Greasing oil duct 18 is injected into the right side of sealing ring 6, and the first lip 13 and the second lip 14 of sealing ring 6 are moistened
It is sliding, the life-span of sealing is extended, while the greasing of shield machine has certain pressure, this pressure acts on the He of the first lip 13
The back side of second lip 14, also plays a part of auxiliary seal, the back pressure of this lip 14 of first lip 13 and second to dregs
In the presence of the reliability for further increasing dregs sealing.
As shown in figure 5, the native storehouse sealing device also includes mounting ring 19, it is right that the mounting ring 19 is fixedly mounted on native storehouse
In the shield body 1 of side and it is set in the connecting shaft 4, first mounting groove 2 is arranged on the right side of the connecting shaft 4,
The mounting hole 3 is arranged on the bottom land of first mounting groove 2 and by the left side of mounting ring 19 and the groove of the first mounting groove 2
Bottom is connected.
First mounting groove 2 and mounting hole 3 are arranged in mounting ring 19, mounting ring 19 and shield body 1 are split type structures,
When carrying out the first mounting groove 2 and the processing of mounting hole 3, it is only necessary to be processed mounting ring 19, then mounting ring 19 is installed to
In shield body 1, difficulty of processing can be so reduced, it is ensured that the quality of processing.
The left end of the connecting shaft 4 is fixedly connected with the cutterhead 7 of shield machine, and the right-hand member of the connecting shaft 4 and center are turned round
Section 20 is fixedly connected.The connecting shaft 4 is tubular structure, and some are provided with the inner chamber of the connecting shaft 4 by cutterhead 7
Interface 22 and central rotary joint 20 at the flexible pipe 21 that mutually correspondence is connected of interface 22.
Flexible pipe 21 connects cutterhead 7 and central rotary joint 20, is deposited when to the position of interface 22 on cutterhead 7 and central rotary joint 20
In site error, it can be connected and simply be corrected by flexible pipe 21, so both alleviate the mass of connecting shaft 4, reduced again
The difficulty of processing of connecting shaft 4.
