Description
Technical field
It the utility model is related to tower crane frame field, and in particular to a kind of complete split type spelling tower crane for being readily transported and stacking
Frame.
Background technology
Tower crane is that a kind of most common crane gear, tower crane pass through a section tower crane frame in architectural engineering（Or it is
Tower crane section, standard section of tower crane）Assembling is built, and tower crane frame is generally by four main chords, more diagonal web members, cross bar and connection set group
Into.
Traditional tower crane section assemble method is as follows：First main chord is welded and fixed by diagonal web member, cross bar etc., connector,
Alignment pin original paper is welded at the both ends of main chord, then by large-scale lathe by the positioning hole forming of alignment pin original paper, so shaping
Tower crane frame be the very big monoblock type of size frame structure, can not be split between each parts, when carrying out positioning hole machined
Very inconvenient, processing efficiency is relatively low；Need first to determine main chord, diagonal web member etc. by frock during welding fabrication
Position, is then needed to weld successively in multiple angles, substantial amounts of welding sequence be present, and welding procedure, Forming Quality and processing are imitated
Rate has large effect.
Moreover, the tower crane frame being so molded transports in use, because tower crane frame sheet is as space frame structure after shaping,
Size is again larger, and space-consuming is big, and a usual lorry can only carry several tower crane frames, larger to compartment space waste, relatively
