One end of each support angle bar is detachably fixed with one main angle bar, and the other end of each support angle bar is detachably fixed with the other main angle bar. Connecting ribs are arranged between two adjacent support angle bars, two ends of each connecting rib are detachably fixed with the corresponding end heads of one support angle bar respectively, and the connecting ribs and the two support angle bars form a W shape. The straight lines of two adjacent connecting ribs intersect.
Description
Technical field
The utility model relates to a kind of tower crane, and relating in particular to a kind of pylon and cantilever all is by the assembled tower crane of a plurality of elementary cells, belongs to the elevator machinery field.
Background technology
Tower crane of the prior art generally has pylon, and install on the ground the lower end of pylon, and upwards towering in the upper end of pylon, is rotatably equipped with cantilever in the upper end of pylon, and cantilever also is strip structure.Tower crane pylon and cantilever belong to tall and slender structure, and suffered primary load comprises hang oneself its gravity, wind loading and the relevant dynamic load of weight of the gravity of self, cantilever, is in curved, as to press combination complicated applied force state.In order better to distribute internal force, to optimize structure, reduce wind loading, present pylon and cantilever generally all are to adopt truss structure.
Consider transportation and assembly unit requirement, the pylon of present tower crane is generally according to the standard cell design manufacturing, and the pylon standard block is the framed structure of rod member welding, and the height of standard block is more than 2m, and the length of side is generally also about 2m.Standard block single-unit quality is heavy, the standard block volume is large, the traffic requirements full size vehicle, and carrying needs elevator machinery, and on-the-spot bolt or the pin of using connects.
At present the cantilever of tower crane generally is designed to the truss structure of rod member welding, and the tower crane of different model is along with hoisting capacity is different with boom reach, and the length of cantilever has tens meters not wait to up to a hundred meters.The cantilever quality is several tons or tens tons, according to the overlength Transportation Organization, needs full size vehicle during transportation, and carrying needs elevator machinery, and on-the-spot bolt or the pin of using connects.
Existing tower crane adopts welded structure, the single-piece quality is large, maintenance cost is high, in addition, tower crane standard block and the cantilever of different model are diversified in specifications, the type steel model that uses is also different, and the tower crane of different model needs different manufacturing process and matching tooling, makes and organizes comparatively complexity.
Simultaneously, tower crane standard block and cantilever elementary cell contour dimension is large, quality is large, transportation is inconvenient with carrying, and transportation is high with landed cost.In the mountain area or the poor area of road engineering factor use and be restricted.
Secondly, tower crane standard block and cantilever elementary cell are welded structure, when the situation such as indivedual Deformation Member, damages occurring in transportation, carrying and use procedure, can only change whole unit, and maintenance cost is high.
Moreover tower crane standard block and cantilever elementary cell are welded structure, weld defect occurs easily, affect service life, have reduced and have repeated the number of times that assembly unit is used.Have emergentness because welding destroys, occur easily because member and weld fatigue destroy the safety misadventure that causes in use procedure.
Summary of the invention
The purpose of this utility model is to provide a kind of tower crane, take solve in the prior art because of tower crane standard block and cantilever elementary cell as welded structure in transportation, carrying and use procedure in case the situations such as indivedual Deformation Member, damages occur, just can only change whole unit, cause the high problem of maintenance cost.
For achieving the above object, the utility model adopts following technical scheme: a kind of tower crane, comprise that pylon and rotation are assemblied in the cantilever of pylon upper end, described pylon and cantilever are assembled by rod member, described pylon and cantilever include two leading role's steel that are parallel to each other, on both length directions, equidistantly be laid with an end and removable the fixing of leading role's steel between two leading role's steel, the other end and another root leading role steel are removable fixing and perpendicular to the support angle steel of two leading role's steel, adjacent two support be provided with between the angle steel two ends respectively with corresponding termination of supporting angle steel removable fixing and with two support the dowels that angle steel form W shapes, the straight line at adjacent two dowel places intersects.
It is all removable fixing by two connecting panels and two leading role's steel that each supports angle steel, the outside of two connecting panels is removable being fixed on leading role's steel respectively, the inboard of two connecting panels is removable fixing with the two ends of supporting angle steel respectively, the two ends of described dowel respectively by with corresponding two connecting panels between removable fixingly fix with corresponding support angle steel termination is removable, the two ends of dowel are respectively on the removable part that is fixed between the corresponding leading role's steel of being in of corresponding connecting panel and the support angle steel.
All pass through bolts assemblies between described leading role's steel, support angle steel and dowel and the connecting panel.
Pylon of the present utility model and cantilever are assembled by rod member, the annexation that forms leading role's steel, the dowel of pylon and cantilever and support between the angle steel is removable fixing, it is little to that is to say that the utility model was loose mail single-piece quality before assembling, interchangeability is strong, be conducive to improve the manufacturing process standardization level, be convenient to realize the lean manufacturing.And if the rod member damage appears in transportation or use procedure, and can change corresponding rod member by the scene and keep in repair, reduce because service expenditure is saved in the wasting of resources that becomes the section replacing to cause.And because single-piece quality and institute's duty are all less, can realize the transportation of Container Transport or containerization, can or lack in the situation of large-scale handling machinery in the transportation difficulty, rely on manually carry and assembly unit fully, save transportation and trucking expenses.
