Description
Technical field
The present invention relates to shield machine construction technical field, more particularly to a kind of shield tail brush and fast disassembly type tail sealing device of shield.
Background technology
The advanced method that Urban Metro Construction is subway work mainstream, soil pressure balance shielding are carried out using shield machine driving technology
Structure machine is constructed, and existing tail sealing device of shield is made of three tail sealing brushes and two oil pockets.Shield machine in tunneling process,
Elastic steel sheet, the steel wire of tail sealing brush should keep the state mutually extruded with the section of jurisdiction formed by concrete lining all the time, by
This forms two closed grease chambers；After injecting grease to grease chamber, one of closely knit grease collar will be formed and be close to section of jurisdiction
Outer surface, so as to close the gap between shield shell and section of jurisdiction, forms the plug of sealing pressurize, sealing when reaching driving, section of jurisdiction with
The purpose only starched when Dong Bi gaps are in the milk.However, tail sealing has the following disadvantages in the prior art：
（1）Former tail sealing brush mounting means is uniformly to arrange welding along 360 ° of circumferential directions of tail shield inner wall, due to shield tail brush number
Amount is big, and generally at 300 or so, time-consuming and laborious using welding manner installation, efficiency is low；
（2）Often worked a bid section, need to all exclude shield tail brush and weld again；In tunneling construction, such as need to change
The shield tail brush damaged, need to move into welding equipment in tunnel, and extremely inconvenient, execution conditions are severe, and time-consuming.

The setting of plate not only facilitates the self-strength of enhancing shield tail brush body, and brush filament layer can also be suppressed and fixed to keep away
Exempting from brush filament layer, brush filament spreads out during the work time.
Improved as one kind to shield tail brush of the present invention, be additionally provided with and multiple detachably connect between said base and pedestal
Fitting.The setting of the removable connector is beneficial to further enhance the bonding strength between pedestal and pedestal, and will not increase and tear open
Unload, install the difficulty of shield tail brush body.
Improved as one kind to shield tail brush of the present invention, said base outer surface is enclosed with seal.Seal
Setting help to strengthen the sealing performance of pedestal and pedestal installation, that is, be beneficial to enhancing shield tail brush body and shield tail brush mounting base peace
The sealing performance of dress.
Improved as one kind to shield tail brush of the present invention, above-mentioned pedestal inner surface is equipped with reticulate pattern.The reticulate pattern with it is upper
State seal and mutually extrude the multi-stage sealed effect that can be realized and be installed between pedestal and pedestal, shield tail brush body greatly improved
The sealing performance installed between shield tail brush mounting base.
Present invention also offers a kind of fast disassembly type tail sealing device of shield for including above-mentioned shield tail brush, including tail shield housing, on
State tail shield inner walls and be equipped with least one support ring, and the support ring is equipped with multiple pedestals, and pedestal is internally provided with base
Seat.
In fast disassembly type tail sealing device of shield of the present invention, support ring is mainly used for mounting body, and is set inside pedestal
There is pedestal, such design is so that form grease chamber, and cause the fast disassembly type tail sealing dress between two neighboring support ring
The structure put is more simple, reliable, it is even more important that after pedestal is installed on pedestal inside, two neighboring pedestal appearance
Face is wrapped up in the seal set and can mutually be pushed against to block existing gap between two neighboring pedestal, is conducive to strengthen the fast disassembly type
The sealing performance of tail sealing device of shield.In addition, because fast disassembly type tail sealing device of shield of the present invention includes the shield of said structure
Ventral brush, therefore the fast disassembly type tail sealing device of shield also has the advantages that to be rapidly assembled and disassembled shield tail brush, easy to use.
Improved as one kind to fast disassembly type tail sealing device of shield of the present invention, circle of multiple above-mentioned pedestals along support ring
All inner walls are evenly distributed in support ring.Multiple pedestals are uniformly distributed along the circumferential inner wall of support ring, help to further enhance
The sealing performance of the fast disassembly type tail sealing device of shield, so as to prevent the grease in grease chamber from oozing out.
It is all to be not specifically noted in addition, in technical solution of the present invention, can be by using normal in this area
Rule means realize the technical program.
