Hanging ladder 1-1 is laid along column on the downside of main beam structure 1-3, the top of hanging ladder 1-1 arranges operating room 1-4.
A kind of manufacture method of the dual-purpose straddle truck of this utility model is:Relatively shield machine assembles straddle truck and straddle truck of slagging tap The similarities and differences in version, retain identical version;After shield machine assembling is completed using assembling straddle truck, will assembling Straddle truck is transformed, and keeps straddle truck supporting leg track parallel with tunnel axis direction, and straddle truck is across slagging tap well in tunnel Well head, two oppositely oriented cable drums of fit on, it is left-handed, close steel near deceleration pusher side that cable drum rotation direction is Cord reel pedestal side is dextrorotation.A lifting cross beam is equipped with every trolley simultaneously, 2 groups of dynamic cunnings are installed on the top of crossbeam Wheel group, bottom install 2 dregs bucket suspension hooks, while complete on cable drum and running block steel wire rope winding (due to Cable drum and running block is changed, has needed to change the canoe of steel wire rope);In the two root posts of straddle truck both sides Slag dumping support meanss are installed, 2 (per root posts 1) are installed on every heel post, 4 altogether, the spacing of support meanss is according to slag The size of soil bucket determines that support meanss are welded on the column of straddle truck.When dregs is unloaded, 2 on every heel post support dress The dregs bucket supported in homonymy tunnel is put, in the presence of suspension hook, makes the rollover of dregs bucket complete slag dumping work.
The assembling straddle truck that this utility model is related to transform the straddle truck slagged tap as, and concrete transformation and operational approach are such as Under:
(1) after shield machine assembling straddle truck installs assembly work that is ready and smoothly completing shield machine, change protorosaur door Hang on the reel 1-6 in trolley, it is desirable to which the rotation direction of cable drum is in opposite direction with former cable drum, i.e. steel wire rope It is left-handed near reductor 2-1 sides that winding direction is, is dextrorotation near wire rope roll cylinder base side.
(2) a lifting cross beam 1-8 is equipped with every trolley, 2 groups of movable pulleys are installed on the top of lifting cross beam 1-8 Group 1-7, bottom install 2 dregs bucket suspension hook 3-3, arrange 2 lifting cross beams altogether.Complete steel wire rope 3-1's on assembly pulley 1-7 Winding so that when dregs bucket suspension hook 3-3 or lifting cross beam 1-8 or main suspension hook 3-2 raisings, cable drum rotate counterclockwise (observing from deceleration pusher side).
(3) support meanss 1-10 of dregs bucket are installed in two root posts 1-2 of straddle truck both sides, are installed on every heel post 2 (per root post 1), 4 altogether, the spacing of support meanss is determined according to the size of dregs bucket, the casing 5-2 of support meanss It is welded on the column 1-2 of straddle truck.The slag in 2 support device homonymy tunnels when dregs is unloaded, on every heel post Soil bucket 1-9, dregs bucket 1-9 complete slag dumping operation by rollover hook rollover under the support of support meanss 1-10 draw-in groove 5-1.
Above-mentioned detailed process is:, after tunnel portal completes dress soil, lifting cross beam 1-8 is with reel 1-6 for dregs bucket 1-9 Rotation gradually transfer to hole;The suspension shaft 4-1 of dregs bucket 1-9 is caught on the suspension hook 3-3 that slags tap, operation trolley 1-5 delays Slow lifting dregs bucket 1-9, after dregs bucket 1-9 reaches ground certain altitude, moves horizontally trolley 1-5, makes dregs bucket 1-9 Support shaft 4-2 be respectively supported in the draw-in groove 5-1 of two heel post upper box 5-2;It is slow to decline lifting cross beam 1-8, dregs bucket 1-9 will be turned on one's side around support shaft 4-2 under gravity, so as to complete deslagging work.The follow-up above-mentioned behaviour of slag dumping work repetition Make.
(4) after shield-tunneling construction completes to slag tap, straddle truck of slagging tap can be transformed back original shield assembling straddle truck, makes dragon Gantry crane possesses the function of dismounting shield machine, and the project of transformation is just contrary with above-mentioned steps.
By optimizing configuring technical and the shield-tunneling construction scheme of straddle truck, after the assembling that straddle truck completes shield machine, Necessary transformation is carried out to which so as to possess slag-tapping function, be used for dregs, a tractor serves several purposes can be realized, reduce straddle truck Configuration quantity, reduce the buying expenses of straddle truck, save human and material resources, substantially reduce construction space, big straight There is extensive popularization and reference value in the earth pressure balanced shield, EPBS construction of footpath.
It is although the above-mentioned accompanying drawing that combines is described to specific embodiment of the present utility model, not new to this practicality The restriction of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability Various modifications or deform still in protection model of the present utility model that field technique personnel are made by need not paying creative work Within enclosing.
