Detailed description of the invention
Now further illustrate the present invention by reference to the accompanying drawings how to implement, in Fig. 1, arrow points is front along the bridge.
Bridge Erector of the present invention comprises mainframe, pillar construction, front launching nose structure, cable wire rope, retaining mechanism, running mechanism, hoisting system, mainframe is formed by connecting (see Fig. 4,5,6) by left and right frame back timber 1-1, left and right frame bottom girder 1-2 and frame lateral system 1-3 through framework pillar 1-4; Pillar construction contacts 2-2 by left and right two root post 2-1 through upright post flat and is formed by connecting; Left and right two column 2-1 symmetry is fixed in the frame back timber 1-1 leading section, left and right of mainframe, has node C(to see Fig. 1,7,8); Front launching nose structure is formed by connecting through front launching nose lateral system 3-2 by two, left and right front launching nose 3-1; Two front launching nose 3-1 pass through hinge (see Fig. 1,9,10) with the left and right frame back timber 1-1 front end of mainframe respectively; Left and right pillar 2-1 top O is respectively equipped with four and connects hanger, and left and right frame back timber 1-1 is connected hanger F, E, B, A with left and right front launching nose 3-1 is interval with respectively; Left and right pillar 2-1 top O four hangers separately, to connect with connection hanger F, E of left and right frame back timber 1-1 and company's hanger of left and right front launching nose 3-1 respectively by cable wire rope 4-4,4-3,4-2 and 4-1 that B, A are corresponding is connected anchoring; Two cover running mechanisms 6 are laid in immediately below the frame bottom girder 1-2 of left and right respectively, and each two cover hoisting systems 7 in left and right are separately positioned on the two front launching nose 3-1 of left and right, and left and right Ge Liang cover locking mechanism 5 is separately positioned on mainframe, correspondingly with setting up beam section Y connects.
