Abstract
The invention discloses a double independent driving system for a shield machine, which comprises a front shield housing, a central cutting knife plate, a main knife plate, a soil bin, a cutting ground outlet and a screw conveyor, wherein the central cutting knife plate is mounted in the center of the main knife plate of the shield machine; and a central knife independent driving device is mounted above the central cutting knife plate. The double independent driving system has the benefits that as the central knife independent driving device is mounted above the central cutting knife plate, the central cutting knife plate can rotate fast to break lithosphere, and the main knife plate rotate in a low speed to break a soft soil layer, so as to ensure that the speeds of the main knife plate and the central cutting knife plate are the same while being used for breaking special stratums, which realizes the smooth excavation of the shield machine.
Description
Technical field
The present invention relates to a kind of shield machine, relate in particular to the two independent driving systems of a kind of shield machine.
Background technology
Shield machine is the special engineering that is used to the tunnel machinery in a kind of constructing tunnel; The cutterhead velocity of rotation of large-diameter shield machine is very low; Be generally per minute one right side of turning left, when shield machine passes through viscous soil horizon, can can't turn round because of the obstruction of the clay of compacting after fixed because cutterhead is positive; Other peripheral soil body is almost motionless especially relatively in the centre of major diameter cutterhead, greatly reduces the operating efficiency of shield machine; Yet when in the process of driving, running into some special stratum; Be when being the stratum of hard formation below the weak soil layer above for example running into, shield machine is under the huge geological conditions of two-layer attribute difference, because rock stratum stability is high; This moment cutterhead can the cutting moment of torque to occur huge; And shield machine housing and only produced the frictional force of part between the stratal surface that tunnels, when moment of friction can't balance knife cutting stratum the moment of torsion that the soil body produced the time, will cause the vibrations of shield machine self.Will produce some bad influences after the shield machine vibrations, as influence the assembly unit of section of jurisdiction, even can damage the section of jurisdiction, also can cause the deflection of tunnel axis.
Summary of the invention
The object of the present invention is to provide the two independent driving systems of a kind of shield machine, the center cutter rotating speed that occurs in the present constructing tunnel is too small can't realize the problem of driving smoothly to solve.
The object of the invention is realized through following technical scheme:
The two independent driving systems of a kind of shield machine; Comprise anterior shield housing, central cutting cutterhead, operator dish, Tu Cang, the outlet of cutting ground, conveying worm; The center of said shield machine operator dish is equipped with the central cutting cutterhead, and center cutter drive device is installed on the said central cutting cutterhead.
Especially; Said center cutter drive device carries out transmission by bearing and drive sleeve; Said drive sleeve is connected with the transition panel through bolt; The rotary inner ring of said transition panel and secondary base bearing is through Bolt Connection, and the rotary inner ring of said secondary base bearing is provided with internal gear and matches with the external gear of the output of secondary drive system, and the rotation outer ring of said secondary base bearing and secondary drive system are passed through Bolt Connection on the main casing of secondary base bearing; The main casing of said secondary base bearing links to each other through the load-carrying ring of bolt and cutterhead, and the rotation inner ring that is provided with internal tooth of base bearing matches with the gear of output end of main drive system; The static outer ring of base bearing links to each other through bolt with the base bearing main casing, and said main drive system is fixed on the base bearing main casing.
Especially, on the said central cutting cutterhead single-blade hobboing cutter and twolip hobboing cutter are installed.
Especially, said central cutting cutterhead is installed in the cutterhead of the annulus a that is welded with two symmetries and annulus b in the heart, and the central cutting cutterhead can rotate within it.
Especially, be provided with the MULTIPLE DYNAMIC sealing between transition panel and the main casing, and can relatively rotate.
Especially, rotary joint is fixed in the commentaries on classics of base bearing main casing, and said rotary joint is connected with the output hydraulic circuit with the input hydraulic pressure oil circuit, and the output hydraulic circuit is connected with the secondary drive system of hydraulic motor.
Beneficial effect of the present invention is: owing on the central cutting cutterhead center cutter drive device is installed; So can realize central cutting cutterhead quick rotation; In order to cracking lithosphere, the operator dish slowly runs cracking the weak soil layer, thereby realizes that operator dish and central cutting cutterhead are when cracking some special stratum; The progress that guarantees the two is consistent, to realize the smooth driving of shield machine.
