The specific embodiment
As shown in Figure 1, in when construction, be provided with respectively at least three continuous bridge piers 601,602,603 can be voluntarily front leg strut 501, middle supporting leg 502 and rear support leg 503 (rear support leg 503 also become claim the back auxiliary supporting leg).Front leg strut 501, middle supporting leg 502 are fixed between bridge pier 601,602 last times, two front leg struts, are connected with bag hub 503 (as shown in Figure 3) between two middle supporting legs.The front end of girder 400 is hingedly connected with front launching nose 200, the fixed back launching nose 300 (as shown in Figure 2) that is connected with in rear end.Preceding shoulder pole girder 701 is hung front launching nose 200, and middle shoulder pole girder 702 is hung girder 400 (as shown in Figure 4), and back shoulder pole girder 703 is hung girder 400 (as shown in Figure 8).Back walking shoulder pole girder 704 connects rear support leg 503.450 is concrete box girder among Fig. 2.
Shown in figure 13; The front end of girder 400 is hingedly connected with front launching nose 200; Establish the girder frame 401 that is articulated and connected on the girder 400, establish the front launching nose frame 201 that is articulated and connected on the front launching nose 200, be articulated and connected frame 401 and front launching nose of girder is articulated and connected and connects jointed shaft 280 between the frame 201; Be provided with between girder 400 and the front launching nose 200 to change and push away jack 290.Realize the rotation between girder 400 and the front launching nose 200 like this.
Chassis 100 before being provided with respectively on front leg strut 501, middle supporting leg 502 and the rear support leg 503, middle chassis 150 and back chassis 160.Like Fig. 3, shown in 5 and 7; Chassis 150 is identical with middle chassis 100 structures before in the present embodiment.
As shown in Figure 7, hanging beam 705 is established at the two ends of back walking shoulder pole girder 704 respectively, establishes track 706 on the hanging beam 705, establishes running roller 708 on the hanger 707, and running roller 708 is hung on the track 706, is connected traversing jack 709 between hanger 707 and the hanging beam 705.Hanger 707 lower ends are connected fixing with rear support leg 503.The back chassis of establishing on the rear support leg 503 160, it is traversing oily 162 that the back chassis is set between back chassis 160 and the rear support leg 503, and back chassis 160 is provided with fixing girder bracing frame 163 (as shown in Figure 6).When the traversing jack 709 between hanger 707 and the hanging beam 705 can solve girder and back launching nose vertical shift turning, the interference problem between rear support leg 503 and the bridge pier promptly laterally moved rear support leg 503 and avoids rear support leg 503 and bridge pier collision.
Because preceding chassis 150 is identical with middle chassis 100 structures, explains with middle chassis.As shown in Figure 9, middle chassis 100 comprises bogie frame 101, the bearing 102 that is articulated and connected on the bogie frame 101, about in the present embodiment there being bearing 102 two.The axle 103 that is articulated and connected is set, attaching nut 116 on the axle 103 that is articulated and connected between the base plate 104 of bearing 102 and the bogie frame 101.Establish hinge hole 105 in the present embodiment on the base plate 104, the axle 103 that is articulated and connected passes the bearing of establishing in the hinge hole 105 106.Also be provided with rotational support pad 107 between bogie frame 101 and the bearing 102; Said structure can realize that chassis when supporting the girder rotation, reduces turning radius.Be connected with removable anti-rotation pull bar 108 (shown in figure 11) between bearing 102 and the bogie frame 101, when vertical shift reaches fixedly, guarantee that bearing 102 does not rotate (when needing to rotate, removing anti-rotation pull bar 108) like this.
Bearing 102 is provided with support platform 109, and support platform 109 is through back shaft 110 and bearing 102 in the present embodiment.Support platform 109 is commonly called as balladeur train.One side of bearing 102 is provided with guide roller 111, and is shown in figure 10; About support platform 109 and guide roller 111 on two bearings 102 steady can guarantee the girder vertical shift time.
Like Fig. 9, shown in 11, bogie frame 101 is provided with sideslip oil cylinder 112.Sideslip oil cylinder 112 is connected with track on the middle supporting leg, and chassis 100 is traversing in the realization.
Like Fig. 9, shown in 11, also be provided with the longitudinal-moving device 120 of absolute altitude adjustment jacking cylinder 113 and girder on the bogie frame 101.Absolute altitude adjustment jacking cylinder 113 tops are provided with hinged-support 114, and adpting flange 115 is set on the hinged-support 114.
The longitudinal-moving device 120 of girder is like Fig. 9, shown in 12; It comprises the bracing frame 121 that is located on the bogie frame 101; Bracing frame 121 is provided with vertical shift oil cylinder 122, the piston rod end of the vertical shift oil cylinder 122 vertical shift piston shoes 123 that are articulated and connected, and vertical shift piston shoes 123 are connected with girder 400.Also be connected with anti-skidding stopping device on the bracing frame 121; Anti-skidding stopping device comprises the pull bar 124 that connects on the bracing frame 121, and the end of pull bar 124 connects stopping piston shoes 125, is hingedly connected with unidirectional rocking pin 126 on the stopping piston shoes 125, connects spacer pin 127 on the stopping piston shoes 125.When the girder vertical shift, unidirectional rocking pin 126 is shown the hole on the girder, if girder retreat, the hole that unidirectional rocking pin 126 gets on the girders, spacer pin 128 is spacing with unidirectional rocking pin 126, so unidirectional rocking pin 126 is limited, and avoids girder to retreat.
Said structure makes mould bases have radius box girder construction ability, from satisfying the construction of 400m radius.
