Accompanying drawing explanation
Fig. 1 is the structural representation of shield machine soil sand sealing device;
Fig. 2 is the structural representation of shield machine described in the utility model;
Fig. 3 is the partial enlarged drawing described in Fig. 2.
Detailed description of the invention
Be described further below with reference to accompanying drawing 1 to accompanying drawing 3 pairs of the utility model, but protection domain of the present utility model should do not limited with this.For convenience of explanation with understand the technical solution of the utility model, the noun of locality used below is as the criterion with accompanying drawing.
Contrast accompanying drawing 1 to accompanying drawing 3:
Native sand sealing device 0 described in the utility model comprises lip ring 20 and the ring packing base 10 for pressing described lip ring 20; Arrange sealing plate 30 in the upper end of ring packing base 10, sealing baffle plate 30 is fixed on the top of ring packing base 10 by the mode of welding.An annular pressing plate 40 is established at the right side card of ring packing base 10, this annular pressing plate 40 is fixed by fixture 50, this fixture 50 is the fixture of annular, and arranges flange 501 within it, the cavity that the flange 501 that described annular pressing plate 40 is just fastened on fixture 50 is formed.The right-hand member of this annular pressing plate 40 arranges lip ring 20, and this lip ring 20 is lip-type packing; The right-hand member of this lip ring 20 arranges flange 60, and the right side of this flange 60 arranges toroidal cavity 601, and arranges counterbore 602 in the both sides up and down of flange 60.
When concrete enforcement, annular pressing plate 40 is fixed on the right flank of ring packing base 10 by screw 04, and lip ring 20 is near the right flank of described annular pressing plate 40; Flange 60 and ring packing base 10 are oppositely arranged and lip ring 20 is pressed in the left side of this flange 60, and this toroidal cavity 601 is towards right side; When use is installed, in order to ensure that flange cavity 601 forms good sealing state with needing the device sealed, the first sealing ring 01 and the second sealing ring 02 is set at the upper side of this flange cavity 601 and downside.
In shield machine described in the utility model, it comprises cutterhead 1 and anterior shield soil cabin 2, and this cutterhead 1 and anterior shield soil cabin 2 are linked together by cutterhead bracket 3, and the junction in this cutterhead bracket 3 and anterior shield soil cabin 2 arranges cutterhead bracket junction plate 4.At the described anterior shield soil sidewall in cabin 2 and the junction of cutterhead bracket junction plate 4, aforesaid native sand sealing device 0 is circumferentially set; Described native sand sealing device 0 is also set at the inner side place of the cutterhead bracket 3 of the outermost end of cutterhead bracket junction plate 4, cutterhead bracket junction plate 4 part of the cutterhead bracket 3 of the top namely shown in figure simultaneously.Concrete, the native sand sealing device 0 of top is when installation, and the lower end of ring packing base 10 is welded on the left side of cutterhead bracket junction plate 4, and flange 60 is fixed on the sidewall in anterior shield soil cabin 2 by screw through its counterbore 602; The place of sidewall end contact in the right side of flange 60 and anterior shield soil cabin 2 is provided with the first sealing ring 01 and the second sealing ring 02, because flange cavity 601 and the sidewall end face in anterior shield soil cabin 2 form the guide groove of accommodating cooling medium, therefore, the sidewall end face seal in the native cabin 2 of this flange 60 and anterior shield can be ensured by this first sealing ring 01 and the second sealing ring 02.In the process used, in the guide groove that this flange cavity 601 is formed, water or other cooling mediums can be held, reduce the temperature of lip ring 20 with this, ensure its result of use and application life.In addition, owing to having sealing plate 30 in the welded top of ring packing base 10, therefore in shield machine use procedure, can stop that considerable native sand enters, make sealing performance better, longer service life.
