Truss-like crane ' s major girder and jib are the frame constructions of rod member welding, and height reaches as high as several meters more than 1500mm, and the cross section is rectangle, and width is generally also more than 1m.More than the about 15000kg of quality reaches.The traffic requirements oversize vehicle, carrying needs lifting appliance, and on-the-spot bolt or the pin of using connects.
Existing Bridge Erector adopts welded construction, and the single-piece quality is large, and maintenance cost is high, in addition, the Bridge Erector standard block of different model and diversified in specifications, the type steel model of use are also different, the Bridge Erector of different model needs different manufacturing process and matching tooling, makes and organizes comparatively complexity.
Simultaneously, truss-like Bridge Erector end carriage, girder gabarite is large, quality is large, and transportation is inconvenient with carrying, and transportation is high with landed cost.In the mountain area or the poor area of road technical condition use and be restricted.
Secondly, the Bridge Erector standard block is welded construction, 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 the Bridge Erector standard block is welded construction, weld defect occurs easily, affects application life, has reduced and has repeated the number of times that assembly unit is used.Have emergentness because welding destroys, occur easily because member and weld fatigue destroy the security incident that causes in use procedure.
The utility model content
The purpose of this utility model is to provide a kind of Bridge Erector, take solve in the prior art because of the elementary cell of crane ' s major girder as welded construction 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 Bridge Erector, comprise two girders that be arranged in parallel and the jib that two girders are coupled together, the two ends of every girder are all supported and are provided with supporting leg, described girder is assembled by rod member, described girder comprises 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 are supported the dowel that is provided with a pair of composition V-arrangement between the angle steel, the end that a pair of dowel is separated from each other is removable fixing with two adjacent ends that support angle steel respectively, the end that a pair of dowel joins is all on the removable part that is fixed between the other end that corresponding leading role's steel is in two adjacent support bars, and each end that dowel is separated from each other is all towards same leading role's steel.
It is all removable fixing by two junction plates and two leading role's steel that each supports angle steel, two junction plates are fixed on leading role's steel by the outside is removable respectively, the inboard of two junction plates is removable fixing with the two ends of supporting angle steel respectively, the end that described a pair of dowel is separated from each other respectively by with corresponding junction plate between removable the fixing in termination of removable fixing and corresponding support angle steel, the end that a pair of dowel is separated from each other is removable respectively to be fixed on the corresponding leading role's steel of being in of corresponding junction plate and to support on the part between the angle steel, the end that a pair of dowel joins is removable fixing with corresponding leading role's steel by a junction plate, the removable inboard that is fixed on corresponding junction plate of the end that a pair of dowel joins, the outside of this junction plate is removable to be fixed on corresponding leading role's steel.
All pass through bolts assemblies between described leading role's steel, support angle steel and dowel and the junction plate.
Girder of the present utility model is assembled by rod member, and leading role's steel of girder, dowel and the annexation that supports between the angle steel are removable fixing, that is to say that the utility model was loose mail before assembling, the single-piece quality is little, interchangeability is strong, be conducive to improve the manufacture process standardization level, be convenient to realize the lean manufacturing.And if the rod member damage appears in transportation or use procedure, can change rod member and keep in repair the wasting of resources that reduction causes owing to the replacing of one-tenth section, saving maintenance cost by the scene.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.
