Abstract
The invention discloses a rotary joint of a shield machine. The rotary joint comprises an outer sleeve, an inner sleeve and a support wall, wherein the inner sleeve is embedded in the outer sleeve, the inside of the outer sleeve is hollow, the middle of the outer sleeve is connected with the support wall through a screw bolt, one end of the outer sleeve is connected with a baffle disc through a screw bolt, one end of the inner sleeve is connected with a transition disc through a screw bolt, a shaft connected with a cutter disc rotating element is arranged on the transition disc, an annular oil groove arranged in the outer sleeve corresponds to a hydraulic oil hole arranged in the inner sleeve, and a pipe joint is connected onto the hydraulic oil hole.
Description
Technical field
The present invention relates to a kind of shield machine, relate in particular to a kind of shield machine swivel joint.
Background technology
Large-scale shield machine is mainly used in the constructing tunnel, and general employed swivel joint is solid structure, and it is big to take up room, and inside can not be put into other device again, causes the space utilization of each device of shield machine inharmonious.
Summary of the invention
The object of the present invention is to provide a kind of shield machine swivel joint, other device such as the centre drill of in the hollow space of swivel joint, packing into has solved the shield machine interior arrangement irrational problem has been set.
The object of the invention is realized through following technical scheme:
A kind of shield machine swivel joint comprises overcoat, interior cover, supporting walls, is inlaid with interior cover in the said overcoat; Its inside is hollow, and the middle part of said overcoat and supporting walls be by Bolt Connection, one of which end and block plate Bolt Connection; An end and the transition disc of cover link through bolt in said; Said transition disc is provided with the axle that connects the cutterhead revolving part, the said annular oil groove that puts setting outward with said in to put the hydraulic pressure oilhole of setting corresponding, be connected to union on the said hydraulic pressure oilhole.
Further, be connected to high-pressure hose on the said union.
Further, be provided with the high-voltage bidirectional sealing between said overcoat and the interior cover.
Beneficial effect of the present invention is: other the device owing to for hollow, can pack in its inside, save the space; Because an end and the transition disc of interior cover link through bolt; Said transition disc is provided with the axle that connects the cutterhead revolving part; So shield machine swivel joint of the present invention can rotate along with cutterhead together, can make the static liquid in the hydraulic oil hole become mobile liquid with pressure.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is a sectional drawing of the present invention;
Fig. 2 is that the B-B shown in Fig. 1 is to sectional view.
Among the figure:
1, overcoat, 2, interior cover, 3, the high-voltage bidirectional sealing, 4, bolt, 5, transition disc, 6, axle, 7, the hydraulic pressure oilhole, 8, bolt, 9, block plate, 10, annular oil groove, 11, supporting walls, 12, union, 13, hollow parts, 14, bolt.
The specific embodiment
Shown in Fig. 1 to 2, in present embodiment, comprise overcoat 1, interior cover 2, supporting walls 11; Cover 2 in being inlaid with in the overcoat 1 is provided with high-voltage bidirectional sealing 3 between overcoat 1 and the interior cover 2, its inside is hollow parts 13; Hollow parts 13 can wait other device by the mounting center brill, has saved the space, and the middle part of overcoat 1 is connected by bolt 14 with supporting walls 11; Can play the effect of support, the one of which end is connected by bolt 8 with block plate 9; One end and the transition disc 5 of interior cover 2 link through bolt 4, and transition disc 5 is provided with the axle 6 that connects the cutterhead revolving part, and so just the cutterhead of ability and shield machine rotates together.
The hydraulic pressure oilhole 7 of setting is corresponding on the annular oil groove 10 that is provided with on the overcoat 1 and the interior cover 2; Be connected to union 12 on the hydraulic pressure oilhole 7; Be connected to high-pressure hose on the union 12, the hydraulic oil of shield machine needs, low pressure grease, foam sliding agent etc. get in the union 12 entering overcoats 1 through pump like this, get in the annular oil groove 10 again; Get in the hydraulic pressure oilhole 7, along with these liquid of rotation of cutterhead become rotation by inactive state and have the liquid of pressure state.
Claims (3)
