Abstract
The utility model discloses a kind of sealing device and shield machine people's hatch doors, the sealing device includes T connected in star and the lip packing item that is arranged in the T connected in star, the lip packing item includes T shape seal and at least one lip packing muscle, the T shape seal and the T connected in star phase configuration, the top of the T shape seal is arranged in the lip packing muscle, and the lip packing muscle stretches out the setting of T connected in star.The utility model passes through the extruding force of T shape mating surface, and lip packing item and the firm position of T connected in star can be made reliable；Meanwhile lip packing muscle decrement is relatively large, also can preferably guarantee air-tightness requirement when being deformed by sealing element (such as people's hatch door).
Description
Technical field
The utility model belongs to Tunnel Engineering technical field more particularly to a kind of sealing device and shield machine people's hatch door.
Background technique
Shield machine is that a kind of special engineering for tunnel piercing is mechanical, 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 requirement in cabin is higher,
If cabin occurs revealing and will jeopardize the life security of personnel in cabin during carrying out pressurization or pressure maintaining, can also it cause ground when serious
Face sedimentation is even collapsed, and the sealing of people's hatch door is one of maximum structure of airlock sealing area, sealing reliability requirement
It is 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 occurs easily when people's hatch door deforms so as to cause the leakage of people cabin, gives
Operating personnel brings biggish life security risk.
Utility model content
In order to solve the problems, such as that people's hatch door sealing existing in the prior art is insufficient, the utility model provides a kind of sealing dress
It sets and shield machine people's hatch door.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of sealing device, including T connected in star and the lip packing item being arranged in the T connected in star, the lip shape
Sealing strip includes T shape seal and at least one lip packing muscle, the T shape seal and the T connected in star phase configuration, described
The top of the T shape seal is arranged in lip packing muscle, and the lip packing muscle stretches out the setting of T connected in star.
According to the above technical scheme, the bottom of the T shape seal is equipped with dovetail groove.
According to the above technical scheme, viscose glue is coated on the outer surface of the inner surface of the T connected in star and/or T shape seal.
According to the above technical scheme, the lip packing item is double-lip seal item, and the double-lip seal item includes two lip shapes
Sealing bar.
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 star are provided with 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 direction Tu Cang of shield machine.
The beneficial effect that the utility model generates is: groove design is T shape by the utility model, and by lip packing muscle
Seal is designed as the T shape of phase configuration, by the extruding force of T shape mating surface, can make the positioning of lip packing item Yu T connected in star
It is solid and reliable；Meanwhile lip packing muscle decrement is relatively large, it also can be compared with when being deformed by sealing element (such as people's hatch door)
Guarantee air-tightness requirement well.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
