Abstract
The utility model relates to an engine compartment of shield tunneling machine shield cutter head mechanism, which is characterized in that: the outer periphery wall of a hatch (1) of the engine compartment is surfacingly welded with wear-resistant alloy material (2). Through the wear-resistant alloy material (2) surfacingly welded at the outer periphery wall of the hatch (1) of the engine compartment, the engine compartment of shield tunneling machine shield cutter head mechanism can improve the hardness and wear resistance of the surfacing welding part, thereby greatly extending the servicelife of the engine compartment 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.Piggyback pod is the cardiac component of whole drive unit of shield cutter head, and institute is dynamic during shield-tunneling construction is all passed by this piggyback pod.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 the hole wall of earth and force transmission ring enlarged diameter section periphery wall and force transmission ring small diameter bore, piggyback pod hatch periphery wall and seal retainer outer face annular groove constantly produces friction, cause the hole wall heavy wear of the hole wall and the seal retainer outer face annular groove of described piggyback pod hatch periphery wall, 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 piggyback pod like this.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of piggyback pod that can prolong the shield cutter-head mechanism of shield tunnel boring machine in piggyback pod application life greatly is provided.
The purpose of this utility model is achieved in that a kind of piggyback pod of shield cutter-head mechanism of shield tunnel boring machine, and the periphery wall built-up welding of the hatch of described piggyback pod has wear resistant alloy material.
The beneficial effects of the utility model are: the utility model is by the periphery wall build-up wear-resistant alloy material at the piggyback pod hatch, 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 piggyback pod greatly.
(4) description of drawings
Fig. 1 is the piggyback pod 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: hatch 1, wear resistant alloy material 2.
(5) specific embodiment
Referring to Fig. 1～2, the piggyback pod of the utility model shield cutter-head mechanism of shield tunnel boring machine, the periphery wall built-up welding of the hatch 1 of this piggyback pod has wear resistant alloy material 2.
Claims (1)
1, a kind of piggyback pod of shield cutter-head mechanism of shield tunnel boring machine is characterized in that: the periphery wall built-up welding at the hatch (1) of described piggyback pod has wear resistant alloy material (2).
