Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Embodiment of the present utility model is specifically set forth below in conjunction with accompanying drawing.
A rotary joint device for rectangular shield push-bench, described rectangular shield push-bench comprises cutter head, shield structure, drive unit, conveying worm and Rear impact.
A rotary joint device for rectangular shield push-bench as shown in Figure 1, comprises joint shell 2, main drive shaft tail end 3, bearing 7, main shaft end cap 8 and spacer 12.Joint shell 2 is connected in driving box main shaft transparent cover 1 by bolt 11, float between driving box main shaft transparent cover 1 and joint shell 2 and be located by connecting, described floating be located by connecting be stay between joint shell 2 and driving box main shaft transparent cover 1 apertured, when eccentric load is applied to joint shell 2, joint shell 2 just can produce the small size changing of the relative positions relative to driving box main shaft transparent cover 1.Main drive shaft tail end 3 stretches out from the center of driving box main shaft transparent cover 1.
Joint shell 2 is enclosed within main drive shaft tail end 3, and main drive shaft tail end 3 can rotate in joint shell 2 along with main drive shaft.Main drive shaft tail end 3 is upwards provided with passage 5 at central axis, is provided with welding pipeline 6 in passage 5, and welding pipeline 6 is fixing by being welded on main drive shaft tail end 3.Accordingly, main drive shaft tail end 3 is provided with respectively with passage 5 with weld the through hole 13 and through hole 14 that pipeline 6 communicates in radial direction.Joint shell 2 is built-in with respectively the through hole be connected with through hole 14 with through hole 13.The through hole of joint shell 2 is respectively equipped with import A and import B, import A both sides are respectively equipped with revolution Glais ring 4, and import B both sides are respectively equipped with revolution Glais ring 4.Revolution Glais ring 4 sealed outer ring is embedded in the pre-groove of joint shell 2, and revolution Glais ring 4 inner ring and main drive shaft tail end 3 surface are close to.
Welding pipeline 6 in the revolution lattice Lay coil 4 of import A, import A both sides, o shape sealing ring, main drive shaft tail end 3 forms passage A; Passage 5 in the revolution Glais ring 4 of described import B, import B both sides, main drive shaft tail end 3 forms channel B.Wherein, as indicated by the dashed arrow in fig. 1, the flow direction of channel B is as shown in solid arrow for the flow direction of passage A.
Bearing 7 is arranged on the left and right edges of main drive shaft tail end 3 respectively and is embedded in joint shell 2, and bearing 7 lays respectively at the outside of passage A and channel B.Main shaft end cap 8 is connected with main drive shaft tail end 3 by bolt 10, and o shape sealing ring 9 is arranged in main shaft end cap 8.Spacer 12, for the inner ring of floating location left hand edge bearing 7, has gap between left hand edge bearing 7 and spacer 12, and when bearing 7 forward slip of left hand edge, spacer 12 pairs of left hand edge bearings 7 are protected.
Installation process: be first welded on passage 5 by welding pipeline 6 built-in for main drive shaft tail end 3, then clears up passage 5 and welding pipeline 6 dregs; The bearing 7 of spacer 12 and left hand edge is installed; Again revolution Glais ring sealing 4 is all built in joint shell 2, and mates with main drive shaft tail end 3; Then load the bearing 7 of right hand edge, tight a bolt and 11 joint shell 2 is fixed in driving box main shaft transparent cover 1, finally main shaft end cap 8 bolt 10 being built-in with o shape sealing ring 9 is connected on main drive shaft tail end 3.
The course of work: when the jacking of rectangular shield push-bench, the non-homogeneous eccentric load that cutter head produces when cutting stratum is delivered to rotary joint device region by main drive shaft, this load that main drive shaft tail end 3 is subject to passes to joint shell 2 by two, front side bearing 7, and joint shell 2 is fixed on driving box main shaft transparent cover 2 by bolt 11, final load is delivered to stratum by the shield structure of driving box and rectangular shield push-bench, joint shell 2 just can produce the small size changing of the relative positions relative to driving box main shaft transparent cover 1, reduce the impact that non-homogeneous eccentric load seals revolution Glais ring 4, bearing 7 reduces mainly for making main drive shaft tail end 3 and revolution Glais ring 4 seals contact even or offset, thus the life-span of prolongation rotary joint device, bearing 7 inner ring and main drive shaft tail end 3 elastic conjunction, and utilize that spacer 12, main shaft end cap 8 and bolt 10 control axial float water or foam utilization passage A, channel B is injected into cutter head place and carries out injecting the improvement that dregs, swell soil etc. have stirred dregs.The number of passage can be increased according to actual needs.
