Consider transportation and assembly unit requirement, the girder of present transfer crane is generally according to the standard cell design manufacturing, and the standard block of girder 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.
Existing transfer crane adopts welded structure, the single-piece quality is large, maintenance cost is high, in addition, the transfer crane standard block of different model and diversified in specifications, the type steel model that uses is also different, and the transfer crane of different model needs different manufacturing process and matching tooling, makes and organizes comparatively complexity.
Simultaneously, transfer crane standard block contour dimension 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 engineering factor use and be restricted.
Secondly, the transfer crane standard block is 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 the transfer crane standard block is welded structure, weld defect occurs easily, affects service 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 safety misadventure that causes in use procedure.
The utility model content
The purpose of this utility model is to provide a kind of transfer crane easy to maintenance, take solve in the prior art because of the standard knot of transfer crane 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 standard knot, cause the high problem of maintenance cost.
For achieving the above object, the utility model adopts following technical scheme: a kind of transfer crane easy to maintenance, comprise girder, and the leg of the two end supports of girder setting, 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, all has a center connecting plate between per two adjacent support angle steel, each piece center connecting plate all is between two leading role's steel, a side that is respectively equipped with an end and center connecting plate between the both sides of each center connecting plate and the two leading role's steel is removable fixing, being provided with an end between the two ends that the other end and the corresponding removable fixing connecting angle of leading role's steel, each root support angle steel and the corresponding center connecting plate fixes with the termination of support angle steel is removable, the dowel that the other end links to each other with the corresponding termination of center connecting plate.
It is all removable fixing by two connecting panels and two leading role's steel that each supports angle steel, two connecting panels are all by the outside 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, and the corresponding end of corresponding dowel is removable fixing by the removable fixing termination with corresponding leading role's steel on corresponding connecting panel.
All pass through bolts assemblies between described leading role's steel, support angle steel, connecting angle and dowel and connecting panel or the center connecting plate.
Girder of the present utility model is assembled by rod member, annexation between leading role's steel, dowel, support angle steel and the center connecting plate of composition girder is removable fixing, that is to say that girder of the present utility model was loose mail before assembling, the single-piece quality is little, interchangeability is strong, be conducive to improve girder manufacturing process standardization level, be convenient to realize the lean manufacturing.And if in transportation or use procedure, rod member occurs and damage, can change the plane framework maintenance by on-the-spot, reduce owing to become section to change a wasting of resources that causes, save service expenditure.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.
