At present, traditional shield/TBM misses the stop is that boring in orbit installs counter-force support, by shield/TBM propelling cylinder top
Support counter-force supports and shield machine is moved forward, and then reach counter-force supports and carries out subsequent cycle；Shield often moves circulation needs
Having bad luck a Post Orbit, the time that each operation delays is the most, and shield is missed the stop slow and be there is certain potential safety hazard.
Summary of the invention:
In order to solve the problems referred to above, the invention provides the stepping platform that a kind of shield/TBM shield body is quickly missed the stop.
The technical solution adopted for the present invention to solve the technical problems:
The stepping platform that a kind of shield/TBM shield body is quickly missed the stop, including shield body, hydraulic system and electrical system, the bottom of shield body
Both sides are welded with some limited blocks and lifting frame, and described lifting frame is connected with return cylinder and elevating ram by oil cylinder pin, shield
Being provided with flat travelling carriage bottom body, the bottom of described flat travelling carriage is provided with positioning guide pulleys, and flat travelling carriage is provided with pushing tow
Oil cylinder, one end of described pipe bending cylinder is provided with pipe bending cylinder fixture block, and described pipe bending cylinder fixture block is bolted on back seat,
The bottom of described back seat is provided with positioning guide pulleys.
Described lifting frame is divided into upper and lower, upper by oil cylinder pin and lifting frame respectively of return cylinder upper end, lower end
Portion and bottom connect, and described elevating ram upper end is linked together by the top of oil cylinder pin with described lifting frame, described lifting
Oil cylinder lower end is freely placed on concrete foundation face, and described flat travelling carriage and pipe bending cylinder are connected by oil cylinder pin.
Described return cylinder, elevating ram and pipe bending cylinder are by HYDRAULIC CONTROL SYSTEM.
Described hydraulic system is powered by electrical system, and described electrical system system uses 380V alternating current.
Owing to using technical scheme as above, the present invention has a following superiority:
1, the present invention improves the speed of shield stepping, decreases the manpower needed for shield stepping；
2, the present invention uses all-hydraulic transposition stepping, it is achieved that the automated job of shield stepping, improves the peace of shield stepping

Detailed description of the invention:
Can be explained in more detail the present invention by the following examples, the open purpose of the present invention is intended to protect the scope of the invention
All interior changes and improvements, the invention is not limited in the following examples；
The stepping platform quickly missed the stop in conjunction with a kind of shield/TBM shield body described in accompanying drawing, including shield body, hydraulic system 10 and electricity
Gas system 11, the two bottom sides of shield body is welded with some limited blocks 2 and lifting frame 4, and described lifting frame 4 is by oil cylinder pin 7 and returns
Drawing oil cylinder 12 and elevating ram 5 to connect, be provided with flat travelling carriage 1 bottom shield body, the bottom of described flat travelling carriage 1 is provided with location
Directive wheel 3, flat travelling carriage 1 is provided with pipe bending cylinder 8, and one end of described pipe bending cylinder 8 is provided with pipe bending cylinder fixture block 9, described
Pipe bending cylinder fixture block 9 is bolted on back seat 6, and the bottom of described back seat 6 is provided with positioning guide pulleys 3.
Described lifting frame 4 is divided into upper and lower, and return cylinder 12 upper end, lower end are respectively by oil cylinder pin 7 and lifting frame 4
Upper and lower connect, described elevating ram 5 upper end is linked together by the top of oil cylinder pin 7 with described lifting frame 4, institute
State elevating ram 5 lower end and be freely placed on concrete foundation face described flat travelling carriage 1 and pipe bending cylinder 8 by oil cylinder pin 7
Connect.
Described return cylinder 12, elevating ram 5 and pipe bending cylinder 8 are controlled by hydraulic system 10.
Described hydraulic system 10 is powered by electrical system 11, and described electrical system 11 system uses 380V alternating current.
Limited block 2, lifting frame 4 upper end are welded into entirety with shield/TBM shield body, and return cylinder 12 upper end, lower end lead to respectively
Crossing oil cylinder pin 7 to be connected with the upper and lower of lifting frame 4, described elevating ram 5 upper end is by oil cylinder pin 7 and described lifting frame 4
Top link together, described elevating ram 5 lower end is freely placed on concrete foundation face；Positioning guide pulleys 3 has jointly
There is flat travelling carriage 1, and link together；Back seat 6 is bolted with pipe bending cylinder fixture block 9；Pipe bending cylinder fixture block 9 is right
Pipe bending cylinder 8 limits；Pipe bending cylinder 8 is linked together by oil cylinder pin 7 with flat travelling carriage 1.
During work, being connected in return cylinder 12 lower end and lifting frame 4 bottom with oil cylinder pin 7, return cylinder 12 is regained, and drives
Ground is left in lifting frame 4 bottom；Pipe bending cylinder 8 extends, under the effect of pipe bending cylinder 8, elevating ram 5, return cylinder 12 and
Lifting frame 4 and shield/TBM shield body the transmission of the flat travelling carriage 1 with positioning guide pulleys 3 and limited block 2 guiding next
Distance with the 2100mm that moves forward；After shield/TBM shield body reach 2100mm, return cylinder 12 extends, and lifting frame 4 lower end is put off till mixed
During solidifying face, soil, remove the oil cylinder pin 7 bottom return cylinder 12；Elevating ram 5 extends jack-up shield/TBM shield body, make shield/
TBM shield body leaves flat travelling carriage 1 to certain distance；Under the restriction of pipe bending cylinder fixture block 7, pipe bending cylinder 8 piston rod is retracted,
Back seat 6 is with pipe bending cylinder 8 piston rod reach 2100mm；Elevating ram 5 is slowly fully retracted, until shield/TBM shield body drops completely
Falling on flat travelling carriage 1, now a cycle of operation completes.
The most carefully stating part in above content is prior art, therefore does not runs business into particular one and state.
