The frame lateral system of described mainframe is connected between the frame back timber of left and right, between left and right frame back timber and left and right frame bottom girder, connects by framework pillar.
Described pillar construction is connected to form through the upright post flat contact by left and right two root posts.
Described front launching nose structure is connected to form through front launching nose lateral system by two of left and right front launching nose.
Described left and right frame back timber, left and right front launching nose are arranged at intervals with respectively cable wire rope and connect hanger.
Described left and right pillar top is provided with respectively cable wire rope and connects hanger.
The described left and right retaining mechanism that is arranged on mainframe with set up the beam section and be connected.
The utility model adopts the cable-styled flexible structure of oblique pull, and structure is the triangle stress system, 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, good stability during traveling, safety factor is high; Complete machine structure is simple, easy for installation, easily operation, and, from heavy and light, be convenient to the bridge line style and control; When the bridge interval changes, 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 front launching nose lateral system, can satisfy the demand.Therefore, the complete machine transformation is convenient, and applicability is strong, has solved the problems of conventional rigid structure Bridge Erector.

The specific embodiment
Now further illustrate by reference to the accompanying drawings the utility model and how to implement, in Fig. 1, arrow points is the place ahead along the bridge.
The utility model Bridge Erector comprises mainframe, pillar construction, front launching nose structure, cable wire rope, retaining mechanism, running mechanism, hoisting system, mainframe is 1-3 through framework pillar 1-4 be formed by connecting (seeing Fig. 4,5,6) by left and right frame back timber 1-1, left and right frame bottom girder 1-2 and frame lateral; Pillar construction is formed by connecting through upright post flat contact 2-2 by left and right two root post 2-1; Left and right two column 2-1 symmetries are fixed in the left and right frame back timber 1-1 leading section of mainframe, have node C(to see Fig. 1,7,8); The front launching nose structure is that 3-2 is formed by connecting by two of left and right front launching nose 3-1 through the front launching nose lateral; Two front launching nose 3-1 respectively with the left and right 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 and is connected hanger F, E, B, A on left and right frame back timber 1-1 and left and right front launching nose 3-1; Left and right pillar 2-1 top O four hangers separately, company's hanger of connection hanger F, the E by cable wire rope 4-4,4-3,4-2 and 4-1 and left and right frame back timber 1-1 and left and right front launching nose 3-1 connects that B, A are corresponding is connected anchoring respectively; Two cover running mechanisms 6 be laid in respectively left and right frame bottom girder 1-2 under, it is upper that each two covers hoisting system 7 of left and right is separately positioned on left and right two front launching nose 3-1, each two cover lockings mechanism 5 of left and right is separately positioned on mainframe, and sets up the corresponding connection of beam section Y.
While setting a roof beam in place work, as shown in Figure 1, this Bridge Erector is supported on to frame sections Y by running mechanism 6 upper, and makes mainframe 1 and frame sections Y locking (see figure 1) by retaining mechanism 5.By hoisting system 7, hung and treated 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 take axle power as main.Front launching nose structure, pillar construction, cable wire rope 4-1 form the triangle stress system of Δ AOC; Front launching nose structure, pillar construction, cable wire rope 4-2 form the triangle stress system of Δ BOC; The frame back timber 1-1 of mainframe, pillar construction, cable wire rope 4-3 form the triangle stress system of Δ EOC; The frame back timber 1-1 of mainframe, pillar construction, cable wire rope 4-4 form 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 form 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 spacing L2 of bridge changed, only needing the frame back timber lateral of change mainframe was 1-3, and upright post flat contact 2-2 and front launching nose lateral are the lateral dimension of 3-2, can satisfy the demand.Therefore, the complete machine transformation is convenient, and applicability is strong.
