| description | The utility model relates to the field of tools for mine machinery, in particular to a high-strength tool of a shield tunneling machine. The high-strength tool comprises a shank and a body. The body is rectangular; the bottom of the body is welded to the top end of the shank; the body is evenly provided with a plurality of ribs; the ribs evenly incline on the lateral face and upper surface of the body; joints of the ribs and the body are chamfered for transition; the ribs incline at the angle of 120 degrees to 160 degrees; the faces, fixed to the body, of the ribs are smooth; the outer faces, far away from the body, of the ribs are arced; the front of the shank is provided with a mounting hole in a stepped form. The high-strength tool has the advantages that the high-strength tool is simple in structure, convenient to produce and manufacture and low in cost, and the rib structural design and the rectangular body help improve strength of the tool and prolong its service life. |
