Secondly, tower crane standard block and cantilever elementary cell are 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 tower crane standard block and cantilever elementary cell are welded structure, weld defect occurs easily, affect 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 procedure.
The utility model content
The purpose of this utility model is to provide a kind of space truss tower crane, take solve in the prior art because of tower crane standard block and cantilever elementary cell 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 unit and cause the high problem of maintenance cost.
For achieving the above object, the utility model adopts following technical scheme: a kind of space truss tower crane, comprise that pylon and rotation are assemblied in the cantilever of pylon upper end, described pylon and cantilever are assembled by elementary cell, described elementary cell comprises that four of extending along the length direction of pylon or cantilever occupy leading role's steel of position of four ribs of four-prism, two adjacent elementary cells fixedly are bolted together by corresponding removable between both leading role's steel, the removable dowel that is fixed with between an end of one in adjacent two leading role's steel on arbitrary side of four-prism of each elementary cell and the other end of another root, be on any side of four-prism and the straight line at two adjacent dowel places intersects, be in the removable support angle steel that is fixed with in outer end of two leading role's steel on any side of four-prism of the elementary cell of outer end, the removable support angle steel that is fixed with between two splice point of the leading role's steel on arbitrary side of four-prism of two adjacent elementary cells.
Leading role's steel of per two adjacent elementary cells is removable fixing by four pairs of connecting panels respectively, two connecting panels of every pair of connecting panel are all mutually vertical and be on two adjacent sides of four-prism, two elementary cells are mutual corresponding two leading role's steel removable two ends that are fixed on a pair of connecting panel outside respectively in twos, the two ends of corresponding support angle steel are the removable inboard that is fixed on two connecting panels respectively, be in leading role's steel of elementary cell of outer end also by the four pairs of connecting panels and corresponding four removable fixing of support angle steel, be on the external end head of each leading role's steel of elementary cell of outer end and all be fixed with a pair of connecting panel, two terminations supporting angle steel that are in the outer end are separately fixed on two corresponding connecting panels.
All pass through bolts assemblies between described leading role's steel, support angle steel and dowel and the connecting panel.
Pylon of the present utility model and cantilever 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, interchangeability is strong, be conducive to improve the 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.
