Zusammenfassung: | The invention discloses a structure of an auxiliary beam reversing device of an internal climbing type movable arm tower crane and a construction method of the auxiliary beam reversing device. The beam reversing device is composed of two sets of monorail crane I-shaped steel rails, two sets of electric winches, electrical control equipment and the like. The I-shaped steel rail of the monorail crane is fixed on a box beam in a downward hanging mode, and the box beam is fixed on a standard knot outer frame below a tower crane rotation assembly. The electric hoist is composed of a walking mechanism and a hoisting mechanism, the walking mechanism adopts a motor to drive a driving wheel to walk on an I-shaped steel rail, and therefore the electric hoist can reach the position needing to be used. The hoisting mechanism is composed of a traditional winch and used for steel beam reshipment and hoisting operation. And the mechanisms are connected through the gear couplings, so that the problem that the normal work of |
