The flat contact of the frame of described mainframe is connected between the frame back timber of the left and right sides, between left and right sides frame back timber and the left and right sides frame bottom girder, connects by framework pillar.
Described pillar construction by about two root posts connect to form through the flat contact of column.
Described front launching nose structure by about two front launching noses connect to form through the contact of leading Liangping.
Described left and right sides frame back timber, left and right sides front launching nose are arranged at intervals with cable wire rope respectively and connect hanger.
Described left and right pillar top is provided with cable wire rope respectively and connects hanger.
The described left and right sides retaining mechanism that is arranged on mainframe with set up the beam section and be connected.
The present invention adopts suspension cable formula flexible structure, and structure is the triangle stress system, and stressed clear and definite, loading force is disperseed, and front launching nose structure and mainframe adopt articulated joint, and the front launching nose dead load is little, after machine gravity leans on, and good stability during traveling, safety factor height; Complete machine structure is simple, and is easy for installation, operation easily, and from heavy and light, be convenient to the control of bridge line style; When the bridge internode when changing, only need to change the structural hoisting point position of front launching nose and get final product; When two main couple spacings of bridge change, for adapting to the variation of bridge, only need the unified lateral dimension of revising frame, column and the contact of leading Liangping, can satisfy the demand.Therefore, the complete machine transformation is convenient, and applicability is strong, has solved the problems of conventional rigid structure bridge formation machine.

The specific embodiment
Now further specify the present invention by reference to the accompanying drawings and how to implement, arrow points is the place ahead along the bridge among Fig. 1.
Bridge formation machine of the present invention comprises mainframe, pillar construction, front launching nose structure, cable wire rope, retaining mechanism, running mechanism, hoisting system, mainframe by the flat contact of left and right sides frame back timber 1-1, left and right sides frame bottom girder 1-2 and frame 1-3 through framework pillar 1-4 be formed by connecting (seeing Fig. 4,5,6); Pillar construction by about two root post 2-1 be formed by connecting through the flat contact of column 2-2; About two column 2-1 symmetries be fixed in the left and right sides frame back timber 1-1 leading section of mainframe, have node C(to see Fig. 1,7,8); The front launching nose structure by about two front launching nose 3-1 be formed by connecting through leading Liangping contact 3-2; Two front launching nose 3-1 respectively with the left and right sides frame back timber 1-1 front end of mainframe by bearing pin hinged (seeing Fig. 1,9,10); Left and right pillar 2-1 top O is respectively equipped with four and connects hangers, is interval with respectively on left and right sides frame back timber 1-1 and the left and right sides front launching nose 3-1 to be connected hanger F, E, B, A; Left and right pillar 2-1 top O four hangers separately connect by cable wire rope 4-4,4-3,4-2 and 4-1 and the company's hanger that is connected hanger F, E and left and right sides front launching nose 3-1 of left and right sides frame back timber 1-1 respectively that B, A are corresponding to be connected anchoring; Two cover running mechanisms 6 be laid in respectively left and right sides frame bottom girder 1-2 under, about each two cover hoisting system 7 be separately positioned on about on the two front launching nose 3-1, about each two cover locking mechanism 5 be separately positioned on the mainframe, and set up the corresponding connection of beam section Y.
When setting a roof beam in place work, as shown in Figure 1, this bridge formation machine is supported on the frame sections Y by running mechanism 6, and makes mainframe 1 and frame sections Y locking (see figure 1) by retaining mechanism 5.Hung by hoisting system 7 and to treat that frame sections D moves to frame sections Y, treating that the load of frame sections D passes to the front launching nose structure by hoisting system 7, the front launching nose structure is passed to load the frame back timber 1-1 of mainframe by cable wire rope.Because of mainframe with the locking of frame sections Y, the load for the treatment of frame sections D is by the balance with it of frame sections Y, the front launching nose structure only is subjected to the effect of moment of flexure and axle power in this process, but moment of flexure is very little, mainly based on axle power.Front launching nose structure, pillar construction, cable wire rope 4-1 constitute the triangle stress system of Δ AOC; Front launching nose structure, pillar construction, cable wire rope 4-2 constitute the triangle stress system of Δ BOC; The frame back timber 1-1 of mainframe, pillar construction, cable wire rope 4-3 constitute the triangle stress system of Δ EOC; The frame back timber 1-1 of mainframe, pillar construction, cable wire rope 4-4 constitute the triangle stress system of Δ FOC; Frame back timber 1-1, the cable wire rope 4-1 of front launching nose structure, mainframe, cable wire rope 4-4 constitute the triangle stress system of Δ AOF.These triangle stress systems are stressed clear and definite, and loading force is disperseed, and the front launching nose dead load is little simultaneously, and after machine gravity leaned on, the complete machine security performance increased substantially.
When bridge subsection spacing L1 changes, only need to change the structural hoisting point position of front launching nose, can satisfy the demand; When two main couple spacings of bridge L2 changes, only need to change the flat contact of the frame back timber 1-3 of mainframe, the lateral dimension of column flat contact 2-2 and leading Liangping contact 3-2 can be satisfied the demand.Therefore, the complete machine transformation is convenient, and applicability is strong.
