Pin 63 moves.
The installation of progress sediment improvement equipment is needed after installation is complete in the cutterhead 100 and shield body 10 of shield machine, simultaneously
It needs that native storehouse sealing device is installed, cutterhead 100 and central rotary joint is linked together by transition axis 20.Improve Jie of dregs
Matter is just transported to by transition axis 20 in cutterhead 100 by central rotary joint；And the rotation center of cutterhead 100 and the peace of shield body 10
Tankage 11 can there are certain coaxiality errors due to fabricating and assembling.Structure as the present invention passes through floating ring 60
Tu Cang sealings are carried out, when mounted, transition axis 20 and cutterhead 100 are fixed, and the center of rotation of transition axis 20 is just and cutterhead 100
Center of rotation is consistent, and when the outer circle and the center of rotation of transition axis 20 of transition axis 20, there are floating rings during certain coaxiality error 60
It can float in mounting groove 11 along the length direction of slit 62 so that floating ring 60 can be outer with transition axis 20 always
Circle keeps concentric, avoids the situation to shield body 10 or sealing device contact wear due to transition axis 20 caused by bias, and
When floating, floating ring 60 and mounting groove 11 and transition axis 20 are always maintained at the state of sealing, prevent the dregs of Tu Cang from leaking into
Outside also reduces the difficulty of processing using such structure, the concentricity and transition axis 20 of cutterhead 100 and mounting groove 11
The outer circle center of center of rotation and transition axis 20 can allow larger error.
The center rotary joint, including the housing 40 with through-hole and the shaft 50 being inserted into through-hole, the connecting plate
30 connect with the right side of the transition axis 20, and the shaft 50 is fixedly connected with the connecting plate 30, the housing 40
Inner wall is equipped with the media slot 41 of several annulars, and pipe interface 45, the pipeline are offered on the outer wall of the housing 40
Interface 45 is connected with media slot 41, and the third medium channel 51 is arranged in shaft 50, is additionally provided in shaft 50 and is connect perforation 52,
The perforation 52 that connects connects third medium channel 51 with corresponding media slot 41, adjacent Jie of each two on the housing 40
Inner seal structure there are one being set between matter slot 41；
As shown in figure 3, the inner seal structure includes：
Seal groove 42 and oil-way 43, the seal groove 42 and oil-way 43 are opened on the inner wall of housing 40,
The quantity of the seal groove 42 is two, and the quantity of oil-way 43 is one, and the oil-way 43 is arranged on two sealings
Between slot 42；
Greasing mouth 44, the greasing mouth 44 are opened on the outer wall of the housing 40 and are connected with the oil-way 43；
As shown in figure 4, two lippackings 46, two lippackings 46 are separately mounted to two sealings
In slot 42, the pressure-bearing lip 461 of two lippackings 46 is respectively set back to oil-way 43.
Housing 40 and shaft 50 relatively rotate at work, cut-in operation medium in pipe interface 45, and working media flows into
It, should into media slot 41, then among the third medium channel 51 for connecing perforation 52 and reaching shaft 50 by being connected with media slot 41
Considerable is that the flow direction of working media in real work is not limited to such form, it is also possible to be feelings in contrast
Condition, i.e. working media are reached by third medium channel 51 among pipe interface 45.
Sealing between adjacent media slot 41 realizes that inner seal structure ensures in housing by inner seal structure
40 and shaft 50 relatively rotate during, be between each media slot 41 be isolated from each other, independent state.Each 41 liang of media slot
Side closest to lippacking 46 in seal groove 42 pressure-bearing lip 461 all against the direction of the media slot 41, be used to implement Jie
The sealing of 41 both sides of matter slot, the working media in media slot 41 is mostly non-oleaginous working media, and when there are many working media
It waits and contains the pollutants such as solid particle, be filled in the oil-way 43 between the adjacent seals slot 42 and injected by greasing mouth 44
The lubricant grease come in, the lubricant grease can be filled into the rear portion of the pressure-bearing lip 461 of lippacking 46, have lubricated lip always
The lip contact sealing position of shape sealing element 46, and lubricant grease can have certain pressure in itself, can give lip packing
The rear portion of the pressure-bearing lip 461 of part 46 provides certain support force, also certain that lip is contacted mixed work in sealing
Make medium and solid pollution particulate matter therein squeezes out the effect of lip, particulate matter accelerated wear test is avoided to contact sealing.
