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 plane framework 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 a 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, 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 pylon and cantilever generally all are to adopt truss structure.
Consider transportation and assembly unit requirement, the pylon of present tower crane generally manufactures and designs according to standard block, 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 big, 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 to arrive up to a hundred meters and do not wait.The cantilever quality is several tons or tens tons, according to overlength transportation tissue, 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 big, and maintenance cost is high, in addition; The 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 supporting frock, makes and organizes comparatively complicacy.
Simultaneously, tower crane standard block and cantilever elementary cell contour dimension is big, quality is big, 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, tower crane standard block and cantilever elementary cell are welded structure, when situation such as indivedual Deformation Member, impaired destruction in transportation, carrying and use, occurring, can only change whole unit, the maintenance cost height.
Moreover tower crane standard block and cantilever elementary cell are welded structure, occur weld defect easily, influence 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.
Summary of the invention
The purpose of the utility model is to provide a kind of plane framework tower crane; To solve in the prior art, just can only change whole unit and cause the high problem of maintenance cost because of tower crane standard block and cantilever elementary cell are in a single day welded structure situation such as indivedual Deformation Member, impaired destruction occur in transportation, carrying and use.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of plane framework tower crane; Comprise that pylon and rotation are assemblied in the cantilever of pylon upper end; Said pylon and cantilever are assembled by elementary cell; Said elementary cell comprises the two leading role's steel that are parallel to each other that extend along the length direction of pylon or cantilever; Two adjacent elementary cells fixedly are bolted together through corresponding removable between both leading role's steel, removable be fixed with and these two leading role's steel are formed Z-shaped dowels between the other end of an end of leading role's steel of each elementary cell and another root leading role steel, and the straight line at the reinforced rib place of two adjacent elementary cells intersects; Be 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, 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 pylon and the cantilever of the utility model are 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; That is to say that the utility model was loose mail before assembling, the single-piece quality is little, and interchangeability is strong; Help improving the manufacturing process standardization level, be 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.
