The invention discloses an automatic traction system for large-scale tower-type crane standard-knot removal and installation and relates to the technical field of building construction machinery. The automatic traction system solves the technical problem that the existing traction system for tower-type crane standard-knot removal and installation adopts a manual traction method so that operation carried out by removal and installation operators is difficult and has low efficiency. A traction mechanism (5) of the automatic traction system is installed on a tail of a single-track introduction beam (2). An end of the single-track introduction beam (2) is provided with a leading sheave. The traction mechanism (5) passes through and is wound by a traction steel wire rope (6). A long end (7) of the traction steel wire rope (6) bypasses the leading sheave and then is fixed to an introduction trolley (3) by a rope cappel. A short end (8) of the traction steel wire rope (6) is connected to a rope tensioning device (10) on the introduction trolley (3). An introduction trailer (4) is connected to a standard-knot (9) by steel wire ropes. Two sides of the introduction trailer (4) are respectively provided with lifting lugs (11). Two sides of the introduction trolley (3) are respectively provided with angle steel mount points (13).
Description
technical field [0001] The patent of the invention relates to the technical field of construction machinery, in particular to an automatic traction system for installing and dismantling standard sections of various types of tower cranes. [0002] Background technique [0003] See attached Figure 11 , the current general-purpose introduction system for installing and dismantling standard sections of tower cranes uses manpower for traction. The standard section traction system is mainly composed of two introduction beams and an introduction trolley. The introduction device for the installation and disassembly of the standard section of the tower crane that is more common now is composed of three major components: the jacking hook, the introduction beam, and the introduction trolley. Hook the imported trolley, use bolt pins to connect the imported trolley to the standard section, and then lift it to the introduction beam of the standard section where the installation and lowe...
