Specific embodiment
The invention will be further described for shown embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, shield machine fish tail knife assembly includes center flange 1, is installed on the slip-casting mud at the middle part of center flange 1
Mouth, the hanger 13 on center flange and lower surface are fixedly installed in the fish tail knife on the center flange 1.
It is the length direction of fish tail knife parallel to the fish tail knife lower surface and along the direction that the longest edge of lower surface extends,
Two ends on the length direction are the left and right end of fish tail knife, and two end faces on thickness direction are front/rear end,
The enhanced edition 2 for improving intensity is respectively provided with the fish tail knife front/rear end, on the left and right end of the fish tail knife respectively
It is provided with the wing plate 3 for fish tail knife to be connected with the spoke on cutter head of shield machine.The left part or the right part set respectively
There are two blocks of wing plates 3, the both sides of the fish tail knife are symmetricly set on two blocks of wing plates 3 of one end.The wing plate 3
One end is welded with the fish tail knife and the other end is welded with the spoke, and the wing plate 3 is high with the end that the fish tail knife is welded
In the lower surface of the fish tail knife, because above-mentioned design is ensureing the intensity at left and right both ends simultaneously to left and right both ends in pick
Certain new variables when entering, preventing from connecting just has caused junction stress concentration and phenomenon of rupture has occurred.
The fish tail knife include the knife body 4 that lower surface is mutually fixedly connected with the center flange 1, be disposed on it is described
Wearing plate 5 on the upper surface of knife body 4, the upper surface of the knife body 4 is in by left and right end phase median rise shape.The fish
