Abstract
The utility model discloses a kind of shield structure soil shear failure structure, comprise cutterhead, adpting flange, linking arm, described cutterhead and adpting flange in the form of annular discs, described cutterhead and adpting flange are welded together by linking arm, the outer round surface of described linking arm is welded with the wing plate arranged in the shape of a spiral, a kind of shield structure soil shear failure structure of the present utility model, can fully stir the soil body entering native cabin, realize strong stirring, thoroughly stop the formation of mud cake, the utility model improves the dregs velocity of discharge further, improve shield driving speed, not only operating efficiency is high, but also there is easy manufacture, easy installation, low cost and other advantages.
Description
Technical field
The utility model relates to a kind of stirring structure, refers to a kind of shield structure soil shear failure structure for shield machine especially.
Background technology
When balancing earth-pressure shielding machine carries out set of tunneling construction, if through cutting the soil body entering native cabin, not stirred fully, then easily forming mud cake, affect dregs and discharge, time serious, will quality and the progress of engineering construction be affected.
Utility model content
Problem to be solved in the utility model is the deficiency overcome in background technology, provides a kind of shield structure soil shear failure structure, this shield structure soil shear failure structure, adopt special construction, the abundant stirring to the soil body can be realized, strengthen dregs flowing, promote the dregs velocity of discharge further.
For solving the problem, the utility model takes following technical scheme:
A kind of shield structure soil shear failure structure of the present utility model, comprise cutterhead, adpting flange, linking arm, described cutterhead and adpting flange in the form of annular discs, described cutterhead and adpting flange are welded together by linking arm, and the outer round surface of described linking arm is welded with the wing plate arranged in the shape of a spiral.
A corrective measure of the present utility model is: described linking arm is cylindric.
Further improvement of the utility model measure is: the surface soldered of described wing plate has wearing layer.
Further corrective measure of the present utility model is: described wearing layer adopts wear resistance electrode built-up welding to form.
When the soil body enters native cabin, namely during the position of the soil body between cutterhead and adpting flange, along with the rotation of cutterhead, the wing plate that linking arm is helically arranged is also around the central rotation of cutterhead, in rotary course, stir the soil body, make dregs become fluffy state, promote its mobility.For preventing wing plate from wearing and tearing, on the surface of wing plate with wear resistance electrode build-up wear-resistant layer, improve the application life of wing plate.
A kind of shield structure soil shear failure structure of the present utility model, owing to being welded with the wing plate arranged in the shape of a spiral at the outer round surface of linking arm, therefore, a kind of shield structure soil shear failure structure of the present utility model, can fully stir the soil body entering native cabin, realize strong stirring, thoroughly stopped the formation of mud cake, the utility model improves the dregs velocity of discharge further, improves shield driving speed, not only operating efficiency is high, but also has easy manufacture, easily installation, low cost and other advantages.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of shield structure soil shear failure structure of the present utility model, comprise cutterhead 1, adpting flange 2, linking arm 3, described cutterhead 1 and adpting flange 2 in the form of annular discs, described cutterhead 1 and adpting flange 2 are welded together by linking arm 3, and the outer round surface of described linking arm 3 is welded with the wing plate 4 arranged in the shape of a spiral.
Described linking arm 3 is in cylindric.
The surface soldered of described wing plate 4 has wearing layer.
Described wearing layer adopts wear resistance electrode built-up welding to form.
When the soil body enters native cabin, namely during the position of the soil body between cutterhead 1 and adpting flange 2, along with the rotation of cutterhead 1, the wing plate 4 that linking arm 3 is helically arranged is also around the central rotation of cutterhead 1, in rotary course, stir the soil body, make dregs become fluffy state, promote its mobility.For preventing wing plate 4 from wearing and tearing, on the surface of wing plate 4 with wear resistance electrode build-up wear-resistant layer, improve the application life of wing plate 4.
Should be noted that; the foregoing is only preferred embodiment of the present utility model, be not limited to the present embodiment, all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
