On rail 2.15.
2.12 lower end of roller mount is provided with connecting plate 2.16, and connecting plate 2.16 is to be arranged in roller mount 2.12 and horizontal beam
U-shaped structure between 2.8, including the lower flange fixed with horizontal beam 2.8, in the mobile rear and main couple 1 in place of roller mount 2.12
The web of the top flange and the upper and lower edge of a wing of connection that are bolted.By bolt arrangement by connecting plate 2.16 and main couple 1
It is fixed together, can be adjusted in 2 position of front leg strut and complete to lock together the two, avoid generating rolling in use
It is dynamic.
In use, using region according to Bridge Erector, survived by corresponding elevation using multiple section assemblings of relative populations
Quill 2.2 is fixed in fixes sleeve 2.1 by moving sleeve 2.2 by bolt, is then hung main couple 1 by gantry crane
It transports on the assembled bridge floor completed, completes the erection of Bridge Erector.
The position that support base 2.4 is adjusted by secondary overhead traveling crane 3 drives position of the front leg strut 2 on main couple 1 by motor 2.14
It sets, 2 lower end of front leg strut is made to correspond to support base 2.4, adjust the first jacking cylinder 2.3, accurately adjust the vertical height of front leg strut 2,
The lower end of front leg strut 2 is shelved on to the upper surface of support base 2.4.
When Bridge Erector moved across when, quill 2.2 risen by the first jacking cylinder 2.3 of driving, makes it
It is detached from support base 2.4, is moved across after the completion, secondary 3 handling support base 2.4 of overhead traveling crane is below the front leg strut 2 to after moving in place, before adjusting
The position of supporting leg 2 is supported on it again on support base 2.4.
It is as shown in Figures 4 and 53 structural schematic diagram of middle front leg strut of the present embodiment, middle front leg strut 3 is supported on prefabricated bent cap 10
On, middle front leg strut 3 is that upper end is slidably connected to the vertical supporting structure of main couple 1, anchoring lower ends on prefabricated bent cap 10.In before
Supporting leg 3 include along horizontal cross arrangement crossbeam 3.1, on crossbeam 3.1 laterally spaced arrangement two groups of 3.2 and of roller group
Vertical supporting bar 3.3 positioned at 3.1 both ends of crossbeam is provided with lateral pushing structure between two groups of roller groups 3.2.Support rod 3.3
Upper end is fixed on crossbeam 3.1, and lower end is set to for the anchor pole 3.4 fixed with prefabricated bent cap 10, between two support rods 3.3
Stull 3.5 is set.3.3 structure of support rod of the present embodiment is similar to the flexible of quill in front leg strut 2 and fixes sleeve
Structure can vertically adjust the height of entire supporting leg.Roller group 3.2 is slid by driving device drives edge main couple 1, real
The adjusting of 3 position of front leg strut in existing.
Roller group 3.2 includes the sliding bottom 3.6 being socketed on crossbeam 3.1, and lateral pushing structure includes being located at two groups to slide
Lateral pushing oil cylinder 3.7 and gag lever post 3.8 between dynamic pedestal 3.6, the shell of lateral pushing oil cylinder 3.7 are fixed on crossbeam 3.1
On, pushing end is fixed on one group of sliding bottom 3.6, and gag lever post 3.8 is that both ends are hingedly connected in two groups of sliding bottoms 3.6
On the changeable telescoping rod of its axial length.Changed between two groups of sliding bottoms 3.6 by pushing tow lateral pushing oil cylinder 3.7
Distance, the position of centre of gravity of entire main couple 1 can be adjusted, the variation of anchoring lower ends position is adapted to this, when there is the gradient
The stability of main couple 1 can be kept by center-of-gravity regulating position.
The lower end of support rod 3.3 is also equipped with ball hinged support, and the gradient that can adapt to a small range is adjusted, support rod 3.3
It needs to be anchored on prefabricated bent cap 10, therefore lower end is provided with anchor pole 3.4, be anchored on prefabricated bent cap 10 by anchor pole 3.4.
As shown in figure 3, the structural schematic diagram of the middle rear support leg 4 for the present embodiment, middle rear support leg 4 is the present embodiment main couple
1 driving power device, middle rear support leg 4 include the tail trimmer 4.1, vertically arranged for being fixed on 1 both lateral sides lower part of main couple
Attachment beam 4.2 and the cross-brace beam 4.3 that is fixedly connected with two 4.2 lower ends of attachment beam of both ends, tail trimmer 4.1 is along horizontal horizontal
To arrangement, there are the gaps that overhead traveling crane hoist cable passes through between two tail trimmers 4.1, and two attachment beams 4.2 are along horizontal cross interval cloth
Set, upper and lower ends be fixedly connected respectively with tail trimmer 4.1 and supporting beam 4.3 formed with tail trimmer 4.1 and supporting beam 4.3 it is hollow
Cyclic structure.It forms circular hollow structure and is easy for capable of having foot when handling Precast Pier Columns 8, prefabricated bent cap 10 and steel girder 11
Enough passes through space.
