The technical solution of the utility model is: a kind of oblique box beam bridge formation machine, comprise two parallel girders, the door shape crossbeam of girder and anterior crossbeam, afterbody is connected to form rectangular frame, below girder, be provided with middle part walking crossbeam and anterior walking crossbeam, the crossbeam lower end of forwardly walking is provided with the front cross travelling wheel, walking crossbeam lower end, middle part is provided with two middle part travelling wheels (bidirectional walking in length and breadth), and anterior travelling wheel and middle part travelling wheel can slide on the rail of correspondence.Can realize normal bridge erection construction when walking crossbeam in middle part is all vertical with girder with anterior walking crossbeam; When carrying out the oblique bridge erection, described anterior walking crossbeam becomes oblique with girder, connected mode achieves a fixed connection between girder and walking crossbeam by adjusting, anterior walking crossbeam is positioned at same vertical plane with anterior travelling wheel, rail, and two middle part travelling wheels change that to walk on the same one steel rail be to walk on two one steel rails simultaneously.Bridge formation machine of the present utility model is on the basis of existing moulding quadrature box beam bridge formation machine, front portion walking crossbeam and middle part travelling wheel are improved and adjust, bridge formation organizational security after the improvement has been held the stability on bridge formation machine level and the vertical direction, and can do tiltedly laterally walking on rail.
Further feature is: described anterior walking crossbeam links to each other with girder by connecting bearing, and it is parallel with anterior walking crossbeam to connect the straight line that bearing connected into.
Described middle part walking crossbeam intersects vertically with girder and fixedlys connected.
Described anterior walking crossbeam realizes that by the flange combination wherein the bolt hole on the end flanges dish is the arc groove shape with the fixedly connected of bearing that be connected of girder, realizes oblique by the contraposition of reversing between flange.
With respect to prior art, the utlity model has following remarkable advantage:
1, on the basis of existing moulding quadrature box beam bridge formation machine, the front portion walking crossbeam and the middle part travelling wheel of bridge formation machine to be improved and adjust, adjusted bridge formation function is done tiltedly horizontal the walking on rail, finish the erection construction operation of oblique case beam;
2, the original horizontal connected mode of bridge formation machine is constant, and does not all change at other positions, has still kept bridge formation machine integral body stability in the horizontal and vertical directions;
3, the utility model just at the improvement of bridge formation machine walking crossbeam and travelling wheel, does not need to redesign new bridging equipment, has avoided the overlapping investment in the design, has reduced engineering cost.

Among the figure, 1-girder, 2-door shape crossbeam, the anterior crossbeam of 3-, 4-middle part walking crossbeam, the anterior walking of 5-crossbeam, the anterior travelling wheel of 6-, 7-middle part travelling wheel, 8,9, the 10-rail, 11-vertical shift dolly, on 12,12 times-flange, 13-connects bearing, 14-lifts by crane dolly, the 15-strong point.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Oblique box beam bridge formation machine of the present utility model is the reasonable transformation of carrying out on existing moulding bridge formation machine basis, as shown in Figure 1, comprise two parallel girders 1, girder 1 is connected to form rectangular frame with the door shape crossbeam 2 of anterior crossbeam 3, afterbody, below girder 1, be provided with middle part walking crossbeam 4 and anterior walking crossbeam 5, crossbeam 5 lower ends of forwardly walking are provided with anterior travelling wheel 6, walking crossbeam 4 lower ends, middle part are provided with two middle part travelling wheels 7, and anterior travelling wheel 6 and middle part travelling wheel 7 can slide on the rail of correspondence; Described anterior walking crossbeam 5 length are enough, and fixedly connected with 1 one-tenth oblique form of girder, and anterior walking crossbeam 5 is positioned at same vertical plane with anterior travelling wheel 6, rail 8; Rail 9 is parallel double track with rail 10, and parallel with rail 8, and two middle part travelling wheels 7 lay respectively on rail 9 and the rail 10.Length direction two girder 1 upper ends respectively is provided with a rail, is placed with vertical shift dolly 11 on rail, and a lifting dolly 14 is arranged on every vertical shift dolly 11, also is respectively arranged with to connect bearing 13 below the afterbody of girder 1.The rail 8 of anterior walking crossbeam 5 lower ends is arranged on the bent cap, the rail 9 and the rail 10 of walking crossbeam lower end, middle part are arranged on the case beam that frame is good, vertical shift dolly 11 can vertically slide on the rail at girder 1 top, and, connect bearing 13 and mainly play a part girder 1 and the anterior crossbeam 5 of walking by 14 liftings of lifting dolly, installation precast beam.
Described anterior walking crossbeam 5 links to each other with girder 1 by connecting bearing 13, and the straight line that connection bearing 13 is connected into is parallel with anterior walking crossbeam 5.
Described middle part walking crossbeam 4 intersects vertically with girder 1 and fixedlys connected.
Described connection bearing 13 by on the flange 12,12 times fixing, wherein the bolt hole under the end flanges dish 12 is the arc groove shape, carries out flange and can center on reversing of axle center during contraposition up and down, can realize the needs of oblique.
When oblique box beam bridge formation machine of the present utility model is installed, respectively the travelling wheel at the walking crossbeam of front portion and middle part is reequiped and adjust.Anterior walking crossbeam 5 links to each other with girder 1 by connecting bearing 13, it is mobile forward or backward and fixing on girder 1 that one of them is connected bearing 13, make anterior walking crossbeam 5 change the oblique form into the quadrature form that two vertical girders 1 are connected, the angle of its oblique is decided according to the position of job site bent cap, this process is connected and fixed realization by the contraposition of reversing on the flange 12, under 12, as shown in Figure 2; Because anterior walking crossbeam 5 is positioned at same vertical plane with anterior travelling wheel 6, rail 8, corresponding anterior travelling wheel 6 and rail 8 also are adjusted into the form with girder 1 oblique, adjust the anterior travelling wheel 6 in back and can do tiltedly laterally walking on rail 8.
Simultaneously, middle part travelling wheel 7 is also adjusted.Because middle part walking crossbeam 4 is generally approved product, middle part travelling wheel 7 can planar horizontally rotate, and go up this position on construction ground and have enough spaces to utilize, therefore the crossbeam 4 of walking in the middle part of keeping intersects vertically with girder 1 and fixedlys connected, at two middle part travelling wheels rail 9 and rail 10 are set for 7 times respectively, rail 9 is parallel double track with rail 10, and parallel with rail 8, realizes that two middle part travelling wheels 7 do tiltedly laterally walking respectively on rail 9 and rail 10.
Through to after the repacking of the anterior crossbeam of bridge formation machine and middle part travelling wheel and adjusting, the bridge formation machine can be done tiltedly laterally walking on rail, as shown in Figure 4, four strong points of bridge formation machine become trapezoidal layout by original parallelogram, but original crossbeam connected mode does not become, all does not change at other positions yet, has still guaranteed the stability of bridge formation machine at level and vertical direction.During operation, carry out construction operation according to the origin operation method and get final product.
