Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The attached tower cantilevered bale handle in high-altitude, a kind of mountain area purlin crane system as illustrated in the drawing, it comprises English truss braced structures, main beam structure is hung in purlin and jack machinism, English truss braced structures is connected to king-post sidewall, purlin is hung main beam structure and is arranged in English truss braced structures, and jack machinism is arranged on purlin and hangs on main beam structure.
In the present embodiment:
English truss braced structures comprises lower built-in fitting 1 in king-post and upper built-in fitting 3, lower built-in fitting 1 supports 2 with upper built-in fitting 3 by triangular truss and is connected, lower built-in fitting 1, upper built-in fitting 3 and triangular truss support 2 and form stable rigid structures, be used for support top column supporting structural and purlin hang main beam structure, the basis of whole system structure, as the auxiliary operation platform of construction; Traversing and vertical shift space can also be reserved for the steel truss girder component promoted, reduce the height promoted as far as possible.
English truss braced structures and purlin are hung between main beam structure and are provided with column supporting structural, column supporting structural comprises oblique column supporting structural 4 and right cylinder braced structures 5, between oblique column supporting structural 4 and right cylinder braced structures 5 horizontal direction, there is distance, described oblique column supporting structural 4 and right cylinder braced structures 5 lower end are fixed on English truss and support 2 tops, oblique column supporting structural 4 is connected with king-post by king-post built-in fitting 6 with right cylinder braced structures 5 upper end, to strengthen the stability of structure; Right cylinder braced structures 5 top is connected by welding beam 7 and supported purlin hangs main beam structure.Because mountain construction place is limited, setting up of column supporting structural can be arranged according to actual field ground situation, also can arrange separately and also can arrange both sides simultaneously in both sides, left and right limit, its Main Function is: reduce purlin and hang whole height, and reserves traversing and vertical shift space for the component of cantilever end lifting; The English truss braced structures apical side height of adjustment king-post both sides, makes purlin hang main beam structure and is in equilibrium state.
Purlin is hung main beam structure and is comprised purlin and hang girder 8, and purlin is hung girder 8 lower end and is fixedly connected with crossbeam 7, and purlin is hung girder 8 upper end and is equipped with rail 9, and rail 9 is provided with car stop structure 10.
It is three-legged structure that girder 8 cross section is hung in purlin, and purlin is hung girder 8 lower end and is connected with crossbeam 7 by four strong points, can ensure that resistance to overturning and the safety of girder are hung in purlin like this.
Purlin is hung between the cantilever end of girder 8 and king-post and is provided with connecting rod 15, and described connecting rod 15 one end is hung girder 8 with purlin and is connected, and connecting rod 15 other end is connected with the built-in fitting 14 in king-post, and design can increase the stability that girder 8 is hung in purlin like this.
Girder 8 is hung for unit in charge of construction's existing structure in purlin, is connected can be used by amendment local; Rail 9 connects in the usual way; Car stop structure 10 is installed, in order to carry out spacing to it after jack machinism Overstroke according to jack machinism stroke.
Purlin is hung main beam structure and is comprised Main Function and be: component can lift by crane from two ends cantilever; Support jack machinism is traversing to be run with vertical shift; The stroke that restriction jack machinism is traversing within the scope of construction requirement.In addition, according to job site landform, component also can only lift by crane from side cantilever end.
Jack machinism comprises wheeling mechanism 11, traveling mechanism of the larger traveller 12 and hoisting mechanism 13, traveling mechanism of the larger traveller 12 is arranged on rail 9, wheeling mechanism 11 is arranged on traveling mechanism of the larger traveller 12, hoisting mechanism 13 is arranged on the crossbeam of wheeling mechanism 11, and the lower end of hoisting mechanism 13 is by suspension hook and lifting steel truss girder.The lifting of jack machinism as steel truss girder component, the actuating unit of traversing and vertical shift, can select existing equipment or customization according to construction requirement.
The invention has the advantages that:
1, the present invention can realize steel truss girder member lifts, traversing and vertical shift, solves the upper air installing problem of large scale, large wt pts;
2, the present invention is attached on king-post by built-in fitting, solves the problem that landform construction plant, complex mountainous is little;
3, purlin is hung girder and is adopted existing crane main beam structure, and crane is existing product, can reuse, and structure processing and installation process shorten greatly, has feature that is easy for installation, that dismantle simple and fast, can repeat to have enough to meet the need use.
