Detailed description of the invention
In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
See accompanying drawing 1, basis is novel to be made up of seat board 4, slide plate 8, propelling hydraulic cylinder 3, lifting mechanism 1, pull bar 6 and after-poppet 7.Described lifting mechanism 1 is located at seat board 4 front part sides, described after-poppet 7 is connected to seat board 4 rear portion by pull bar 6, described pull bar 6 two ends respectively with seat board 4 and after-poppet 7 hinged, described seat board 4 is provided with the slide plate 8 for supporting TBM front portion above, described slide plate 8 back is provided with propelling hydraulic cylinder 3, otic placode 5 on the other end of propelling hydraulic cylinder 3 and seat board 4 is hinged, and the mounting plate 101 of described lifting mechanism is connected with the left and right side shield of TBM.During work, slide plate 8 is connected with TBM front portion.
See accompanying drawing 2 and accompanying drawing 3, described seat board 4 is parallel is above provided with two protruding guide rails 10, the both sides of seat board 4 are respectively provided with a guiding side plate, and described slide plate 8 both sides are equipped with the directive wheel 9 supporting with the side plate that leads and guide pad 2, slide against on seat board 4 at the driving lower skateboard 8 of propelling hydraulic cylinder 3.Shield at the bottom of TBM is directly seated on slide plate 8, and slide plate 8 is placed on seat board 4 and can slides on seat board 4 together with TBM, and seat board 4 and slide plate 8 directly support TBM front weight.There is directive wheel 9 slide plate 8 both sides, and be limited in the guiding side plate of seat board 4 two ends, described directive wheel 9 and guide pad 2 slide on guiding side plate, and this guiding side plate meets instructions for use.Propelling hydraulic cylinder 3 is connected with slide plate 8 by bearing pin one end, and the other end is connected with seat board 4.Seat board 4 above has slideway, oiling can reduce frictional force between slide plate 8 and seat board 4.Described slide plate 8 there are directive wheel 9 and guide pad 2.
See accompanying drawing 4, before and after described seat board 4 bottom, guide wheel 11 is installed, directly slide on flat concrete base plate 14 during stepping, concrete floor 14 need reserve longitudinally guiding groove along tunnel axis direction, and seat board 4 bottom surface guide wheel 11 has slided stepping guide effect in base plate gathering sill.
See accompanying drawing 5, lifting mechanism by lifting hydraulic cylinder 102, draw and lift hydraulic cylinder 103, guide peg 104, mounting plate 101, bottom plate 105 form, lifting mechanism mounting plate 101 is welded on TBM left and right side shield, for being elevated TBM front weight.After-poppet 7 bolt connects with TBM saddletree, for supporting TBM rearward weight.
See accompanying drawing 6, pull bar 6 two ends link with bearing pin with seat board 4 and after-poppet 7 respectively, and after-poppet 7 is linked by bolt with TBM saddletree, support TBM rearward weight when TBM rear support leg lifts by after-poppet 7.
See accompanying drawing 7, when lifting hydraulic cylinder 102 falls, TBM front weight is seated on slide plate 8 and seat board 4, and when TBM rear support leg hydraulic cylinder lifts, rearward weight drops on after-poppet 7.Utilizing between slide plate 8 and seat board 4 is metal, and its contact friction is little, and between seat board and concrete floor, friction is large, thus there is the principle of frictional drop, promotes slide plate slide forward along seat board together with TBM by propelling hydraulic cylinder.Carry out the next one again after propulsion cylinder stroke terminates and slide circulation, finally make TBM arrive the face that starts.
See accompanying drawing 1 and accompanying drawing 7, adopt the utility model stepping process as follows:
1.TBM rear support leg lifts, and after-poppet 7 is supported in ground to support TBM rear portion; Lifting hydraulic cylinder 102 pressure release, TBM front weight is pressed on slide plate 8 and seat board 4; Lift and draw hydraulic cylinder 103 bottom plate 105 is mentioned to depart from ground to have certain interval.
2. hydraulic power station is that propelling hydraulic cylinder 3 pressurizes, and promotes TBM together with slide plate 8, along seat board 4 slideway forward slip stroke.
3. after propelling hydraulic cylinder 3 propelling reaches a stroke, lift and draw hydraulic cylinder 103 pressure release, bottom plate 105 lands, and lifting hydraulic cylinder 102 and TBM rear support leg hydraulic cylinder connect hydraulic oil, lift TBM front and rear weight respectively.Now TBM front portion is lifted together with slide plate 8, and forms gap between seat board 4, and after-poppet 7 is also lifted away from ground.
4. the propelling hydraulic cylinder 3 of step device shrinks, and drives seat board 4 to move ahead, and simultaneously by the pull bar 6 between seat board 4 and after-poppet 7, after-poppet 7 is also slided forward along the dragging track on TBM girder together with TBM saddletree support boots, completes and change step.
5. lifting hydraulic cylinder 102 falls to making slide plate 8 and TBM front portion be seated on seat board 4, and TBM rear support leg lifts and makes after-poppet 7 flooring support TBM rear portion, enters next stepping and advances circulation.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
