Abstract
The utility model relates to a force-transmitting ring of shield tunneling machine shield cutter head mechanism, which is widely applied to subway, railway, road, municipal or hydropower tunnel project. The force-transmitting ring is arranged as a secondary lug boss shape, the inner ring of the force-transmitting ring is arranged as a secondary step hole shape. The force-transmitting ring of shield tunneling machine shield cutter head mechanism is characterized in that: the outer peripheral wall of a large-diameter section (1) of the force-transmitting ring is surfacingly welded with wear-resistant alloy material (1.1) of the large-diameter section, the hole wall of a small-diameter hole (2) of the force-transmitting ring is surfacingly welded with wear-resistant alloy material of small diameter hole (2.1). Through surfacingly welding the wear-resistant alloy material at the outer peripheral wall of the large-diameter section of the force-transmitting ring and the hole wall of the small-diameter hole of the force-transmitting ring, the force-transmitting ring of shield tunneling machine shield cutter head mechanism can improve the hardness and wear resistance of the surfacing welding part, thereby greatly extending the service life of the force-transmitting ring of shield tunneling machine shield cutter head mechanism.
Description
(1) technical field
The utility model relates to a kind of shield excavation machine.Be widely used in subway, railway, highway, municipal administration or water power construction of tunnel.Belong to technical field of engineering machinery.
(2) background technology
Shield excavation machine is a kind of special engineering machinery of tunnel piercing.That modern shield structure integrates is mechanical, electrical, liquid, sensing, information technology, has the excavation cutting soil body, carries soil quarrel, the assembly unit tunnel lining, measures function such as the correction of leading.Cutter-head mechanism of shield is the core of shield excavation machine.It mainly is made up of cutter plate driver mechanism, connection supporting leg and cutterhead.Described cutter plate driver mechanism mainly is made up of drive motors, piggyback pod, travelling gear, bull gear, force transmission ring and seal retainer.When shield excavation machine is worked at tunnel excavation, drive motors by cutter-head mechanism of shield transmits power, drive the bull gear rotation by travelling gear, again through force transmission ring be connected supporting leg and drive the cutterhead rotation, cutterhead rotary cutting earth is cut earth and is scattered in the cavity that constitutes between cutterhead and piggyback pod, force transmission ring and the seal retainer.Because the continuous rotary work of force transmission ring, the hole wall of earth and force transmission ring enlarged diameter section periphery wall and force transmission ring small diameter bore constantly produces friction, cause the hole wall heavy wear of described force transmission ring enlarged diameter section periphery wall and force transmission ring small diameter bore, and described fray can not be reprocessed in the tunnel, has had a strong impact on the application life of force transmission ring like this.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of force transmission ring that can prolong the shield cutter-head mechanism of shield tunnel boring machine in force transmission ring application life greatly is provided.
The purpose of this utility model is achieved in that a kind of force transmission ring of shield cutter-head mechanism of shield tunnel boring machine, described force transmission ring is arranged to secondary boss shape, it is poroid that the inner ring of force transmission ring is arranged to two stage steps, the enlarged diameter section periphery wall built-up welding of described force transmission ring has the enlarged diameter section wear resistant alloy material, and the hole wall built-up welding of the small diameter bore of force transmission ring inner ring has the small diameter bore wear resistant alloy material.
The beneficial effects of the utility model are: the utility model passes through at the periphery wall of force transmission ring enlarged diameter section and the hole wall build-up wear-resistant alloy material of force transmission ring inner ring small diameter bore, can improve the hardness and the anti-wear performance of described built-up welding part, thereby prolong the application life of the force transmission ring of shield cutter-head mechanism of shield tunnel boring machine greatly.
(4) description of drawings
Fig. 1 is the force transmission ring structural representation of the utility model shield cutter-head mechanism of shield tunnel boring machine.
Fig. 2 is the I enlarged drawing of Fig. 1.
Fig. 3 is the II enlarged drawing of Fig. 1.
Among the figure: enlarged diameter section 1, small diameter bore 2, enlarged diameter section wear resistant alloy material 1.1, small diameter bore wear resistant alloy material 2.1.
(5) specific embodiment
Referring to Fig. 1～3, the force transmission ring of the utility model shield cutter-head mechanism of shield tunnel boring machine, described force transmission ring are arranged to secondary boss shape, and the enlarged diameter section 1 periphery wall built-up welding of force transmission ring has enlarged diameter section wear resistant alloy material 1.1; It is poroid that the inner ring of described force transmission ring is arranged to two stage steps, and the hole wall built-up welding of the small diameter bore 2 of force transmission ring inner ring has small diameter bore wear resistant alloy material 2.1.
Claims (1)
1, a kind of force transmission ring of shield cutter-head mechanism of shield tunnel boring machine, described force transmission ring is arranged to secondary boss shape, it is poroid that the inner ring of force transmission ring is arranged to two stage steps, it is characterized in that: the enlarged diameter section of described force transmission ring (1) periphery wall built-up welding has enlarged diameter section wear resistant alloy material (1.1), and the hole wall built-up welding of the small diameter bore of described force transmission ring inner ring (2) has small diameter bore wear resistant alloy material (2.1).
