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 plane framework transfer crane of a plurality of elementary cells, 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 plane framework transfer crane; With solve in the prior art because of the transfer crane standard block be welded structure in transportation, carrying and use in case situation such as indivedual Deformation Member, impaired destruction occur; 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 plane framework transfer crane; Comprise girder; And the two end supports of girder is arranged on leg; Said girder is assembled by elementary cell, and said elementary cell comprises the two leading role's steel that are parallel to each other that extend along the length direction of girder, and two adjacent elementary cells fixedly are bolted together through corresponding removable between both leading role's steel; Removable being fixed with these two leading role's steel formed Z-shaped dowel between the other end of one end of leading role's steel of each elementary cell and another root leading role steel; The straight line at the reinforced rib of two adjacent elementary cells place intersects, and is in the removable support angle steel that is fixed with in outer end of two leading role's steel of the elementary cell of outer end, and two adjacent elementary cells are the removable support angle steel that is fixed with between two splice point of both leading role's steel.
Leading role's steel of per two adjacent elementary cells is removable fixing through two connecting panels respectively; Two removable respectively two ends that are fixed on a connecting panel outside of the mutual cooresponding two leading role's steel of elementary cell; Two cooresponding each other two removable respectively two ends that are fixed on another piece connecting panel outside of leading role's steel in addition of elementary cell; The removable respectively inboard that is fixed on two connecting panels, the two ends of cooresponding support angle steel; Two leading role's steel that are in the elementary cell of outer end are also fixed through two connecting panels and cooresponding support angle steel are removable; Be in leading role's steel and removable being fixed on the connecting panel of an end of cooresponding support angle steel of the elementary cell of outer end; Be in another root leading role's steel and removable being fixed on another piece connecting panel of the other end of cooresponding support angle steel of the elementary cell of outer end, the two ends of corresponding dowel are removable respectively be fixed on corresponding on the part between the corresponding leading role's steel of being in of connecting panel and the support angle 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 elementary cell; And leading role's steel of elementary cell, 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 reduce owing to become section to change the wasting of resources that causes, practice thrift service expenditure through the maintenance of field replacement plane framework.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.
