The utility model solves the technical scheme that its technical matters adopted: novel body of the tower joint imported unit, and comprise and introduce crossbeam and add regulating device, it is characterized in that:

Described introduction crossbeam is made up of beam body, pull bar, guardrail, block; Described beam body which is provided with pulley bracket and is connected otic placode by two I-beam sections and the angle steel truss structure that is welded; Pull bar and beam body through be connected otic placode, bearing pin is fixed together, the fixed installation guardrail in beam body both sides, at the terminal block of installing of beam body,

The described regulating device that adds is made up of introduction dolly, suspender, transmission device; Introduce dolly and be installed on the bottom wing listrium of beam body master string, below introducing dolly, suspender is installed;

Described transmission device comprises pulley, major axis, minor axis, big gear wheel, miniature gears, reel, handwheel, bracing frame, steel rope; Several pulleys are installed on the pulley bracket of beam body; Front end at the beam body is installed bracing frame; A major axis is installed on bracing frame, is respectively equipped with minor axis in the major axis both sides, reel is sleeved on the minor axis; At the major axis central mounting handwheel is arranged, between major axis and the minor axis through intermeshing miniature gears and big gear wheel transmission; Steel rope is wrapped on the reel, is fixed on the front end of introducing dolly through pulley one end, and the other end is fixed on the rear end of introducing dolly.

The beneficial effect of the utility model: during use, install this novel body of the tower joint imported unit additional in the appropriate location of tower machine, when tower machine jacking supernumerary segment; On ground the suspender of imported unit is connected fasteningly with the body of the tower joint, amplitude variation trolley and suspension hook through tower machine self play sling, and it is hung on the introduction dolly of introduction beam; Installation personnel shakes the handwheel in the imported unit transmission device; Introduce the dolly on the crossbeam through rope traction, be with standard knot together to get in the stock, after the body of the tower of introducing saves main chord and the body of the tower main chord aligns; Handwheel stops operating; Make introduce the body of the tower joint be parked in body of the tower directly over, begin to shrink jacking cylinder, the body of the tower joint that makes introducing and body of the tower with turn round undersetting and link to each other.Squeeze into to connect and use bearing pin, connects fastening after, with suspender with introduce the standard knot disengaging, the contrarotation handwheel makes introduction dolly and suspender shift out stock, begins to prepare next supernumerary segment process.The unloading process of body of the tower joint is the inverse operation of introducing process.The utility model can improve increasing of Large Towers machine and unloading process, and the workmen of being convenient to simple in structure operates, and is safe and reliable, time saving and energy saving.
