Abstract
The utility model relates to a seal retaining ring of shield tunneling machine shield cutter head mechanism, which is widely applied to subway, railway, road, municipal or hydropower tunnel project. The outer end surface of the seal retaining ring is provided with a ring groove (1). The seal retaining ring of shield tunneling machine shield cutter head mechanism is characterized in that: the innerwall of the ring groove (1) of the seal retaining ring is surfacingly welded with wear-resistant alloy material (2). Through surfacingly welding the wear-resistant alloy material at the inner wall ofthe ring groove of the seal retaining ring, the seal retaining 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 seal retaining 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 groove inwall of earth and seal retainer outer face annular groove constantly produces friction, cause the groove inwall heavy wear of described seal retainer outer face annular groove, and described fray can not reprocess in the tunnel, have a strong impact on the application life of seal retainer like this.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can prolong the seal retainer shield cutter-head mechanism of shield tunnel boring machine seal retainer in application life greatly.
The purpose of this utility model is achieved in that a kind of seal retainer of shield cutter-head mechanism of shield tunnel boring machine, and described seal retainer outer face is provided with annular groove, and the groove inner wall overlaying of the annular groove of described seal retainer has wear resistant alloy material.
The beneficial effects of the utility model are: the utility model is by the groove inner wall overlaying wear resistant alloy material at the seal retainer annular groove, can improve the hardness and the anti-wear performance of described built-up welding part, thereby prolong the application life of shield cutter-head mechanism of shield tunnel boring machine seal retainer greatly.
(4) description of drawings
Fig. 1 is the seal retainer 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.
Among the figure: annular groove 1, wear resistant alloy material 2.
(5) specific embodiment
Referring to Fig. 1～2, the seal retainer of the utility model shield cutter-head mechanism of shield tunnel boring machine, described seal retainer outer face is provided with annular groove 1, and the groove inner wall overlaying of the annular groove 1 of described seal retainer has wear resistant alloy material 2.
Claims (1)
1, a kind of seal retainer of shield cutter-head mechanism of shield tunnel boring machine, described seal retainer outer face is provided with annular groove (1), it is characterized in that: the groove inner wall overlaying of the annular groove of described seal retainer (1) has wear resistant alloy material (2).
