Description
Technical field
The utility model relates to a kind of transfer crane, and relating in particular to a kind of girder is by the assembled transfer crane of rod member, belongs to the elevator machinery field.
Background technology
Transfer crane of the prior art generally has the girder of horizontally set, is provided with leg in the two end supports of girder, and leg is used for girder is supported on the ground, and install on the ground the lower end of leg, and the upper end and the girder of leg are fixed.The girder of transfer crane belongs 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, girder, be in curved, press the complicated applied force state that combines.In order better to distribute internal force, to optimize structure, reduce wind loading, present girder generally all is to adopt truss structure.
Consider transportation and assembly unit requirement, the girder of present transfer crane generally manufactures and designs according to standard block, 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 big, 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 big, and 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 supporting frock, makes and organizes comparatively complicacy.
Simultaneously, transfer crane standard block contour dimension is big, quality is big, and transportation is inconvenient with carrying, and transportation is high with landed cost.In the mountain area or the area of road engineering factor difference use and to be restricted.
Secondly, the transfer crane standard block is a welded structure, when situation such as indivedual Deformation Member, impaired destruction in transportation, carrying and use, occurring, can only change whole unit, and maintenance cost is high.
Moreover the transfer crane standard block is a welded structure, occurs weld defect easily, influences 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.
Summary of the invention
The purpose of the utility model is to provide a kind of transfer crane; The elementary cell because of main beam of gantry crane is in a single day situation such as indivedual Deformation Member, impaired destruction appear in welded structure in transportation, carrying and use in the prior art to solve; Just can only change whole unit, cause the high problem of maintenance cost.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of transfer crane; Comprise girder; And the two end supports of girder is arranged on leg; Said girder is assembled by rod member, and said girder comprises two leading role's steel that are parallel to each other, between two leading role's steel on both length directions equidistance be laid with that removable fixing, the other end of an end and leading role's steel and another root leading role steel are removable to be fixed 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 adjacent two ends that support angle steel respectively, and the end that a pair of dowel joins is all removable to be fixed on cooresponding leading role's steel and to be on the part between the other end of two adjacent strut bars, and each end that dowel is separated from each other is all towards same leading role's steel.
It is all removable fixing through two connecting panels and two leading role's steel that each supports angle steel; The outside of two connecting panels is removable respectively to be fixed on leading role's steel; The inboard of two connecting panels 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 through and cooresponding connecting panel between the end that is separated from each other of removable fixing and the removable fixing a pair of dowel in cooresponding support angle steel termination removable respectively be fixed on corresponding on the part between corresponding leading role's steel of being in of connecting panel and the support angle steel; The end that a pair of dowel joins is through a connecting panel and cooresponding leading role's steel; The removable inboard that is fixed on corresponding connecting panel of the end that a pair of dowel joins, the outside of this connecting panel is removable to be fixed on cooresponding leading role's steel.
All pass through bolts assemblies between said leading role's steel, support angle steel and dowel and the connecting panel.
The girder of the 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; It is little to that is to say that the utility model was loose mail single-piece quality before assembling; Interchangeability is strong, helps improving the manufacturing process standardization level, is convenient to realize the lean manufacturing.And damage if rod member in transportation or use, occurs, can keep in repair, reduce, practice thrift service expenditure owing to become section to change the wasting of resources that causes through the field replacement rod member.And because single-piece quality and institute's duty are all less, can realize the transportation of freight container traffic or containerization, can or lack under the situation of large-scale handling machinery, rely on manual work to carry and assembly unit fully, practice thrift transportation and trucking expenses in hard transportation.
