The shield machine provided with the combined sealing system further comprises a hydraulic motor or an electric motor for driving the cutter head, the front shield, a middle shield, long pipes injected with bentonite, a man lock, a hydraulic rotary joint, a screw conveyor, the cutter head and the like, wherein hydraulic power is transmitted to hydraulic cylinders on the cutter head through a centre rotating joint to drive abnormal fan shaped isolating doors to be closed; as the cutter box sealing system is additionally arranged, after the cutter head isolating door sealing system and the rotary sealing system between the cutter head and the front shield are started, the cutter changing operating condition can be improved, and meanwhile through the optimization of the main transmission sealing system, the system sealing function of the shield machine can be added, and the equipment performance of the shield machine can be improved.
Description
Technical field
The present utility model relates to a kind of combination sealing system of shield machine, is applied to subterranean tunnel road heading machinery, for tool changing in construction of underground tunnel provides the condition that facilitates, can improve the equipment performance of subterranean tunnel road heading machinery simultaneously.
Background technology
Main transmission sealing system, gate sealing etc. in the combination sealing system of shield machine have been applied decades for shield machine.But the combination sealing system of shield machine is seldom employed.Although traditional main transmission sealing system, gate sealing have obtained sizable engineering achievement for shield machine, particularly, under severe operating mode execution conditions, the sealing system of this traditional type also exists a lot of problems.
Conventionally shield machine is due to the requirement of soil pressure control in the time of tool changing, and construction maintenance personnel are the Tu Cang that enters with pressure often, not only affects construction speed, and severe operational environment danger.Adopt this novel combination sealing system just can, than being easier to overcome above difficulty, can increase the system sealing function of shield machine simultaneously, improve the equipment performance of shield machine.
Summary of the invention
The object of this invention is to provide and be a kind ofly suitable in construction tool changing and the combination sealing system of the shield machine of shield machine equipment functional performance is provided.
For reaching above-mentioned purpose, technical program of the present invention lies in providing a kind of combination sealing system of shield machine, comprise rotary sealing system and main transmission sealing system etc. between cutterhead isolating door sealing system, girff sealing system, cutterhead and anterior shield; In addition, with the shield machine of this novel combination sealing system also comprise drive cutterhead hydraulic pressure or electro-motor, anterior shield, middle shield, inject bentonitic long tube, Ren Zha, hydraulic rotary joint, helical conveyor, cutterhead etc., the special-shaped fan-shaped isolating door of Hydraulic Cylinder that wherein hydraulic power is delivered on cutterhead by centre revolving joint is closed, and then startup cutterhead isolating door sealing system, swell soil and polymer also can arrive cutterhead front portion by centre revolving joint simultaneously, further increase the result of use of cutterhead isolating door sealing system.
When in normal shield-tunneling construction, main transmission sealing system is activated, and the multi-seal system protection main drive gear in main transmission sealing system is normally worked.In the time changing cutter or soil pressure need to keep necessarily setting value under severe ground condition, owing to having increased cutter box sealing system, so when after the rotary sealing system starting between cutterhead isolating door sealing system and cutterhead and anterior shield, the earth outside Tu Cang is prevented from entering Tu Cang.Additive as swell soil etc. also can be simultaneously therefrom the many long tubes on shield enter the outside of shield in shield machine, anterior shield and cutterhead, increase whereby sealing effectiveness.
According to technique scheme, the present invention has following beneficial effect:
1. due to the rotary sealing system having adopted at shield machine between cutterhead isolating door sealing system, girff sealing system, cutterhead and anterior shield, while carrying out tool changing in shield machine construction like this, be easier to operation, improved safety simultaneously.
2. adopt Novel main transmission seal system can improve the sealing performance of the main transmission of shield machine, improved shield machine equipment performance.
