As shown in figure 1, a kind of preposition mixed spraying mechanism of Open TBM, including operating platform 1 and whitewashing dolly 2, dolly of whitewashing
2 are hinged with operating platform 1, and whitewashing dolly 2 can rotate with the operational platform 1.Operating platform 1 is provided with road wheel, walking
Wheel is arranged in track 5, and road wheel is connected with Shift cylinder 4, and track 5 is welded in TBM main body, and road wheel is in mobile oil
Moved under the drive of cylinder 4 on its track 5, track 5 is welded in TBM main body.Whitewashing dolly 2 is provided with nozzle 3, nozzle 3
Bottom is connected with shotcrete pipe 10.Disconnection is crossed in the connection that shotcrete pipe 10 can efficiently complete pipeline, can adapt to breaking surrounding rock
With complete two kinds of situations of country rock, the progress of other processes is not influenceed.Support frame and operating platform 1 are to departing from the tunnel of shield supporting
Road face is timely, effective supporting, and can realize machinery（It is unartificial）Formula is mixed spray mode and protected automatically.TBM main body
Middle part and top be equipped with track 5, Shift cylinder 4 is fixed on TBM crossbeam, and track 5 and Shift cylinder 4 make operating platform
1 rotates.
Preferably, bull gear 9 is fixed with operating platform 1, whitewashing dolly 2 is provided with travelling gear 8 and drive assembly 7,
Drive assembly 7 is connected with travelling gear 8, and travelling gear 8 is meshed with bull gear 9.Whitewashing dolly 2 passes through the He of drive assembly 7
Travelling gear 8 does gyration on bull gear 9.Drive assembly 7 can drive whitewashing dolly 2 to move, the work of its dolly 2 of whitewashing
Industry area can cover whole section, 360 ° without dead angle, comprehensive covering region herein.
Preferably, operating platform 1 divides for symmetrical two parts, operating platform 1 include symmetrical left arcuate structure and
Right arcuate structure, left arcuate structure and right arcuate structure include the front arc structure and rear arc structure being parallel to each other, left arc
Shape structure and right arcuate structure are separate structures, motion that can be independent.Whitewashing dolly 2 be arranged on front arc structure and
Between rear arc structure, bull gear 9 is fixed on the middle part of front arc structure, and whitewashing dolly 2 passes through roller and rear arc structure phase
Connection, allows whitewashing dolly 2 to be moved up and down around operating platform 1, convenient that tunnel various pieces are carried out with mixed spray.Whitewashing dolly
