Description
Technical field
The present invention relates to shield machine technical field, more particularly to a kind of shield machine center steering body leakage-preventing sealing device.
Background technology
Center steering body is the important component part of shield machine hydraulic pressure, water gas system, at the same be also measurement cutterhead rotating speed and
The important device of the cutterhead anglec of rotation, its Main Function is as follows：1) additive foam or bentonite addition are conveyed to cutter head panel
Agent, to improve dregs performance, beneficial to the conveying of dregs；2) to cutterhead backbreak knife or imitation-shaped knife delivery hydraulic pressure oil, there is provided knife of backbreaking
Or the power that imitation-shaped knife is flexible, while carrying out the transmission of signal to the flexible stroke of knife of backbreaking；3) rotating speed and the wink of cutterhead are measured
When the anglec of rotation.
Act on based on more than, center steering body gyroaxis must keep being rigidly connected with cutterhead is excavated.In Japanese Mitsubishi, little
In the brand shield machine such as pine, center steering body gyroaxis is generally divided into two parts：Anterior gyroaxis is connected by bolt with cutterhead,
To prevent native storehouse dregs and aqueous vapor to anterior shield internal leakage, lip packing is installed in anterior shield dividing plate and gyroaxis contact position；Afterwards
Portion's gyroaxis then carries out ring flange and is connected by bolt and front portion.During shield machine construction, due to support pressure mistake
The sealing surface of big or lip packing enters dregs, and the sealing lip that may make lip packing is pressed anti-or Fast Wearing, causes Tu Cang
Pressure drop, dregs or underground water are poured in inside anterior shield, are caused the sedimentation on ground or even are caved in.When lip packing serious wear or
When function is lost, it is necessary to change sealing ring in time, and changing such sealing ring needs to disassemble anterior gyroaxis, because of underground activities bar
Part is severe, and narrow space, pressure is higher, dangerous larger, disassembles anterior gyroaxis extremely difficult；Meanwhile, when sealing is changed, shield
Structure machine must stop operation, and the such sealing of general replacement needs 7-10 days, duration nervous even schedule delays be caused, to construction party
Bring huge economic loss.Further, since vibrating larger in shield machine construction, cutterhead and gyroaxis connecting bolt are likely to result in
Loosen, and then cause gyroaxis axis deviation, further result in the leakage of lip packing.Based on above reason, it is necessary to invent

It is arranged in the first spherically mounted seat 2 and firm banking 1 by screw thread.Needing to adjust the first spherically mounted seat and firm banking
The axis direction along shield machine gyroaxis relative position when, fastening bolt of outwarding winding makes the first ball by turn puller bolt
Face mounting seat moves to the position of needs, that is, realize the adjustment of the amount of axially engaging of the first spherically mounted seat 2 and firm banking 1,
Then the relative position of the two is locked by the second spherically mounted seat is locked on firm banking by fastening bolt again.Separately
Outward, between sealing plate and the first spherically mounted seat, the relative position between sealed installing seat and the second spherically mounted seat can
Realized using structure like above, structure is identical with principle, will not be described here.But it is important to note that above-mentioned tune
In whole structure, between the first spherically mounted seat and firm banking in adjustment, what essence was adjusted is the tune of the first spherically mounted seat
The depth of whole insertion firm banking, i.e. axial displacement.And between the first spherically mounted seat and sealing plate, and the second sphere
It is due to being all the sphere-contact for adopting between them, i.e., identical when relative position between mounting seat and sealing installing plate is adjusted
The sphere-contact in the center of circle, therefore when their relative position is adjusted, what is substantially played is aligning effect.
In addition, between the firm banking and anterior shield dividing plate, the lateral surface of the adjustment portion of the first spherically mounted seat with
Between the medial surface of the firm banking, between the first spherical outside surface of the first spherically mounted seat and the first Internal Spherical Surface of sealing plate,
And second spherically mounted seat the second spherical outside surface and the second Internal Spherical Surface of sealed installing seat between be respectively equipped with O-ring seal,
To reach best sealing function.
The gyroaxis connecting plate is two semicircular structure.Plus man-hour, overall processing, subdivision is two semicircular after processing, is passed through
Bolt and gyroaxis flange jointing plate, gyroaxis connecting plate subdivision is that after two semicircular structure, each welding on semicircle end face connects
Steel plate is connect, through hole is designed with steel plate, after being connected with gyroaxis ring flange in order to gyroaxis connecting plate, two semicircular structure can be with
It is again coupled to be integrally formed by bolt.
The second spherically mounted seat is provided with rubber plate washer with the contact surface of gyroaxis connecting plate.
After sealing device is installed, seal grease is injected in annular seal space first with the grease holes on sealing plate, treated
Start cutterhead after grease is filled in annular seal space to be operated.
As can be seen here：1) ensure sealing property by the device need not disassemble gyroaxis, substantially reduce maintenance cycle, change
It has been apt to working environment；2) device can adjust impact of the gyroaxis axis deviation to sealing structure, it is ensured that sealing structure
Sealing property；3) device installs whole parts in installation process by need to only disassembling the pipeline in center steering body case,
It is convenient and swift.
