Abstract
The utility model discloses a rotatable tearing cutter for a shield tunneling machine. The rotatable tearing cutter comprises elastic clamps, a cutter holder, an abrasion-resistant layer, a hard alloy head and a hard alloy blade and also comprises a cutter formed by a cutter handle and a cutter bit; the lower part of the cutter bit is a cylinder; the upper part of the cutter bit is a truncated cone body; the top end of the truncated cone body is provided with a braze hard alloy head cylindrical hole; seven braze hard alloy blade grooves are arranged at the periphery of the truncated cone body; the elastic clamps are clamped in the inner groove on the excircle of the cutter handle and the outer groove in a cylindrical hole of the cutter holder; the cutter is mounted in the cylindrical hole of the cutter holder by the cutter handle and the elastic clamps; the cutter holder is welded on a cutter disc of the shield tunneling machine by a chamfer on the bottom surface; the abrasion-resistant layer is arranged on the outer surface of the cuter bit by surfacing. The rotatable tearing cutter for the shield tunneling machine is high in safety factor, lower in cost, and capable of effectively solving the problem of non-uniform abrasion of the traditional tearing cutter of the shield tunneling machine, so the service life of the cutter is prolonged, the risk brought by the fact that the cutter of the shield is frequently replaced is reduced, and compared with the traditional cutter, the rotatable tearing cutter has certain advantages.
Description
Technical field
The utility model relates to constructing tunnel field, the rotatable cutter of tearing that particularly a kind of shield machine is used.
Background technology
Along with developing rapidly of urban track traffic, shield method tunnel construction is used widely.Especially in the higher stratum of sandy gravel content, be welded on the tearing cutter uneven wear of tearing for stratum trench digging on cutterhead serious, application life is shorter.And at present, in similar stratum, how to solve the problem of shield machine tearing cutter uneven wear, there is no good reply solution.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the shortcoming of above-mentioned background technology, a kind of cutter hub rotatable tearing cutter of rotating shield machine on tool rest is provided, make hard alloy head, hard metal tip, cutter hub on it first-class in construction even wearing, thereby rationally utilize Hardmetal materials, improve application life.
The technical solution of the utility model is: the rotatable cutter of tearing of a kind of shield machine, it comprises elastic card, tool rest, wearing layer, hard alloy head, hard metal tip, also comprise the cutter hub being formed by cutter hub handle and cutter hub head, described cutter hub head bottom is cylinder, top is truncated cone body, the top of truncated cone body is provided with cylindrical hole, external week of truncated cone is provided with seven grooves, on described cutter hub handle cylindrical, be provided with the inner groovy that clamps elastic card, described hard alloy head is brazed in the cylindrical hole of cutter hub head by its underpart cylinder and transition body, described hard metal tip has in seven seven grooves that are brazed in respectively in cutter hub head periphery, described elastic card is installed in the inner groovy and the outer groove in tool rest cylindrical hole on cutter hub handle cylindrical, described cutter hub is installed in the cylindrical hole of tool rest by cutter hub handle and elastic card, tool rest is welded on the cutterhead of shield machine by the chamfering on bottom surface, wearing layer heap is welded on the external surface of cutter hub head.
Described elasticity khaki shape is the cover body with opening, and two ends are provided with easy-disassembling-assembling chamfering.
Its shape of described tool rest is cylindrical body, and the angle of its bottom surface and axis is at least 10 degree to 20 degree, and is provided with the large chamfering for welding, and lower end is also provided with the rectangular aperture for dismounting cutter hub.
The shape of described hard alloy head is that its upper end is truncated cone body, and truncated cone body lower end is thick cylinder, and thick cylinder lower end is for the transition body of soldering and thin cylinder.
The beneficial effects of the utility model are: the utility model safety factor is high, and cost is lower, efficiently solve the problem that shield machine tradition is torn cutter uneven wear, extended cutter life, reduce the risk that the frequent tool changing of shield structure brings, compared conventional tool, had some superiority.

The specific embodiment
The present embodiment is the rotatable cutter of tearing of a kind of shield machine, and it comprises elastic card (1), tool rest (2), wearing layer (5), hard alloy head (6), hard metal tip (7), also comprises the cutter hub being comprised of cutter hub handle (3) and cutter hub head (4).
As shown in Figure 1, cutter hub head (4) bottom is cylinder, top is truncated cone body, the top of truncated cone body is provided with cylindrical hole, external week of truncated cone is provided with seven grooves, on described cutter hub handle (3) cylindrical, be provided with the inner groovy that clamps elastic card (1), described hard alloy head (6) is brazed in the cylindrical hole of cutter hub head by its underpart cylinder and transition body, described hard metal tip (7) has in seven seven grooves that are brazed in respectively in cutter hub head (4) periphery, described elastic card (1) is installed in the inner groovy and the outer groove in tool rest (2) cylindrical hole on cutter hub handle (3) cylindrical.
As shown in Figure 3, Figure 4, described cutter hub is installed in the cylindrical hole of tool rest (2) by cutter hub handle (3) and elastic card (1), tool rest (2) is welded on the cutterhead (8) of shield machine by the chamfering on bottom surface, as shown in Figure 2, wearing layer (5) heap is welded on the external surface of cutter hub head (4).
Described elastic card (1) is the cover body with opening, and two ends are provided with the chamfering that is easy to demolition, installation.
Described tool rest (2) is cylindrical body, and the angle of its bottom surface and axis is at least 10 degree to 20 degree, and is provided with the large chamfering for welding, and lower end is also provided with the rectangular aperture for dismounting cutter hub.
The shape of described hard alloy head (7) is that its upper end is truncated cone body, and truncated cone body lower end is thick cylinder, and thick cylinder lower end is for the transition body of soldering and thin cylinder.
Adopt after said structure, because the number of hard metal tip (7) is odd number, the suffered resistance of tearing cutter cutter hub periphery during work is asymmetric, force it in the upper rotation of tool rest (2), make the wearing and tearing such as hard alloy head (6) on it, hard metal tip (7) be tending towards even, thereby rationally utilized Hardmetal materials, improved application life.
