Background technology
High speed development along with China's modernization economic construction, construction of tunnel building cause take subway as representative just is surging forward, such as underground warehouse, water conservancy hole letter, the large-scale tunnel engineering construction such as highway, railway tunnel is more and more, the Shield Construction Method Used method is widely used in the tunnel construction, and not only efficient is high for it, safety is good, and economic environmental protection, be the optimal selection of modern during construction of tunnel, and shield machine is the modern professional equipment of using in the Shield Construction Method Used method.Heavy tearing cutter is to replace hobboing cutter to be installed in cutter head of shield machine under the sand gravel geology condition to be used for the dedicated tool that sandy gravel is peeled off in cutting, they or combination install or be arranged separately on the cutterhead and when constructing tunnel by in the injection sand-pebble layer, cutterhead is realized revolution under whirligig drives simultaneously, makes heavy tearing cutter knock continuously to prize to peel off to sandy gravel and makes its fragmentation.
Shield machine cutter comprises handle of a knife, cutter hub in the prior art, and the cutting edge of described cutter hub is provided with the groove that extends along edge direction, is welded with cemented carbide body in the described groove.The shield machine cutter of this structure in use; because the groove periphery of cutter hub cutting edge section does not arrange the abrasionproof safeguard measure of cemented carbide body; so during the higher soil of the lithosphere in running into the tunnel or grit layer isodensity; the wearing and tearing of cutter hub cutting edge are very fast; be easy to make the cemented carbide body in the cutter hub cutting edge section groove to come off, cutting-tool's used life is shortened, so just increased the replacing number of times of cutter; thereby increased construction cost, affected construction speed.
Summary of the invention
In order to address the above problem, the purpose of this utility model provides a kind ofly has sufficient intensity, each basil of knife edge part is reasonable, abrasion resistance good and install and change the heavy tearing cutter of shield machine that can adapt to easily all kinds of sand gravel geology conditions.
For achieving the above object, the utility model adopts technical scheme as described below:
The heavy tearing cutter of a kind of shield machine, comprise cutter hub, major cutting edge, auxiliary knife edge and assistant alloy post tooth and cutter shaft, described cutter hub two sides all offer step groove, described major cutting edge connects firmly in step groove, the cutter hub top offers U-lag, described auxiliary knife edge is embedded in the U-shaped groove and exceeds the cutter hub end face, and described assistant alloy post tooth connects firmly front end face and the rear end face at cutter hub; The front end face of cutter hub is provided with shoulder hole, and described cutter shaft one end connects firmly in shoulder hole, and the other end is positioned at the cutter hub outside.
For better implementing the invention, described cutter hub is set to rectangle, and along the cutter hub width two step grooves is set at least.
Further, the front end face of described cutter hub and rear end face are equipped with wearing layer.
Further, described auxiliary cutter alloy column tooth is set at least four rows.
Owing to adopt technique scheme, the utlity model has following superiority:
Heavy tearing cutter described in the utility model rigidly fixes welding by the shoulder hole that cutter shaft passes on the cutter hub, be installed on the cutterhead of shield machine, face the face that excavates by major cutting edge and auxiliary knife edge that carbide alloy forms, when rotating, cutterhead revolves round the sun with cutterhead, equally face is knocked continuously at sandy gravel face image-stone craftsman's chisel and to excavate out ring-shaped groove, smash closely knit sand-pebble layer loosening and peel off; And the various blade anterior angles of heavy tearing cutter itself, relief angle and drift angle are reasonable, low cost of manufacture, structural strength is reliable, anti-wear performance is good, impact resistance is large, changes easy accessibility in the tunnel, can Effective Raise application life of heavy tearing cutter.
