Abstract
The invention discloses a kind of sealing device and shield machine people's hatch doors, the sealing device includes T connected in stars and the lip packing item that is arranged in the T connected in stars, the lip packing item includes T shapes seal and at least one lip packing muscle, the T shapes seal and the T connected in stars phase configuration, the lip packing muscle is arranged at the top of the T shapes seal, and the lip packing muscle stretches out the setting of T connected in stars.The present invention can make lip packing item and the firm position of T connected in stars reliable by the extruding force of T shape mating surfaces；Meanwhile lip packing muscle decrement is relatively large, also can preferably ensure air-tightness requirement when being deformed by sealing element (such as people's hatch door).
Description
Technical field
The invention belongs to Tunnel Engineering technical field more particularly to a kind of sealing device and shield machine people's hatch doors.
Background technology
Shield machine is a kind of special engineering machinery for tunnel piercing, be widely used in subway, railway, highway,
The Tunnel Engineering such as municipal administration, water power.People cabin (also referred to as people's lock or airlock) is the important safety equipment of shield machine, it is mainly used
In shield driving on the way operating personnel with the needs for being pressed into cabin.As manned pressure vessel, the air-tightness in cabin is more demanding,
If cabin occurs revealing and will jeopardize the life security of personnel in cabin during carrying out pressurization or pressurize, can also it cause ground when serious
Face sedimentation is even caved in, and the sealing of people's hatch door is one of maximum structure of airlock sealing area, sealing reliability requirement
Higher.
Currently used people's hatch door sealing device, it is as shown in Figure 1 and Figure 2, close although the installation of this sealing device is simple
Envelope positioning is unreliable, and seal compression deficiency easily occurs when people's hatch door deforms and revealed so as to cause people cabin, gives
Operating personnel brings larger life security risk.
Invention content
In order to solve the problems, such as that people's hatch door existing in the prior art sealing is insufficient, the present invention provide a kind of sealing device and
Shield machine people's hatch door.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of sealing device, including T connected in stars and the lip packing item that is arranged in the T connected in stars, the lip
Sealing strip includes T shapes seal and at least one lip packing muscle, the T shapes seal and the T connected in stars phase configuration, described
Lip packing muscle is arranged at the top of the T shapes seal, and the lip packing muscle stretches out the setting of T connected in stars.
According to the above technical scheme, the bottom of the T shapes seal is equipped with dovetail groove.
According to the above technical scheme, it is coated with viscose glue on the outer surface of the inner surface of the T connected in stars and/or T shape seals.
According to the above technical scheme, the lip packing item is double-lip seal item, and the double-lip seal item includes two lips
Sealed muscle.
According to the above technical scheme, the lip of the lip packing muscle is towards identical.
A kind of shield machine people hatch door, including people's hatch door ontology and above-mentioned sealing device, the T connected in stars are opened in people's hatch door
The both ends of ontology.
According to the above technical scheme, the lip of the lip packing muscle is towards the directions Tu Cang of shield machine.
The beneficial effect comprise that：Groove is designed as T shapes by the present invention, and the seal of lip packing muscle is set
The T shapes of phase configuration are calculated as, by the extruding force of T shape mating surfaces, can make the firm position of lip packing item and T connected in stars can
It leans on；Meanwhile lip packing muscle decrement is relatively large, also can preferably be protected when being deformed by sealing element (such as people's hatch door)
Demonstrate,prove air-tightness requirement.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing：
