(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of balance arm of tower-type crane direction to adhere to detaching device, and it comprises: bracing frame, row's rope sheave, holder rope sheave, suspension hook, rope Locking device, Novel balance arm direction attachment detaching device is welded on equilibrium arm, and described row's rope sheave is fixed on bracing frame with holder rope sheave by two bearing pins, described suspension hook is QTZ63 suspension hook, be fixed on bracing frame foot channel-section steel by two bearing pins at ordinary times, when the attachment of equilibrium arm direction removed by needs time, crane arm suspension hook is risen to top, extract two pulley pin shafts on the suspension hook on equilibrium arm bracing frame out a part, the main rope loosened is made to put into lifting hook pulley, bearing pin fixes after putting into by main rope again, row's rope sheave put into by the main rope in winch direction, and ensure that anticreep works, the main rope in tower cap direction is put into rope Locking device and is locked, then the bearing pin fixing suspension hook on bracing frame is extracted out, off the hook operation is carried out at operator's compartment, suspension hook falls thereupon, be down to attachment place to be removed and carry out dismounting operation.
Preferably, support frame as described above is fixed on tower machine equilibrium arm, and be positioned at directly over the attachment of equilibrium arm direction, height is a little less than winch cylinder.Adopt 10# channel-section steel to be welded, overall one-tenth cuboid, the upper and lower space of suspension hook is left in centre.
Preferably, described row's rope sheave is namely near the pulley of winch position, and this pulley can horizontally slip on bearing pin, can the row's of playing rope effect.
Preferably, described holder rope sheave is namely near the pulley at tower cap place, and this pulley, without the need to horizontally slipping, only plays the effect of holder rope when removing equilibrium arm attachment.
Preferably, described suspension hook uses QTZ63 suspension hook main hook, and two pulley pin shafts of suspension hook can easily be extracted out and fix, and winner is restricted and can put into wherein, suspension hook has certain deadweight, can prevent rope woolding in suspension hook dropping process.
Preferably, described rope Locking device, fixing above holder rope sheave, use loose-leaf rotating manner and by bolt by tight for main rope clamp.
(3) beneficial effect
Attachment detaching device in equilibrium arm direction of the present utility model by increasing a bracing frame, row's rope sheave, holder rope sheave, rope Locking device, suspension hook, the recycling original power of master winch and main rope on equilibrium arm.Making, when removing the attachment of equilibrium arm direction, can vertically hang attachment up-and-down movement, avoiding and using the suspension hook in crane arm direction to carry out oblique pull attachment when removing, brace bar attachedly acutely rock the potential safety hazard brought aloft along with suspension hook.
