Description
Affiliated technical field
The utility model is that the maintenance cantilever of tower crane hangs, and lifting mechanism parts, torque arm mechanism components and the electric cabinet etc. that can utilize cantilever to hang will will to keep in repair on the tower machine hang ground.
Background technology
The maintenance cantilever of at present domestic tower crane hangs and can only rotate and luffing, but when being hung in rotation, cantilever is easy to run into miscellaneous part, such as equilibrium arm pull bar etc., so just can not rotate by 360 degree, cause some parts can hang less than, thereby such cantilever hangs the effect of just not playing lifting fully.
Summary of the invention
When being hung in rotation, above-mentioned cantilever is easy to run into miscellaneous part in order to overcome, the utility model re-constructs the structural shape of cantilever beam, change original fixed boom beam into cantilever beam and 4 synthetic movable boom beams of roller set, cantilever is hung can both freedom 360 be rotated, and gives full play to the effect of its lifting.
The technical scheme that its technical matters that solves the utility model adopts is:
The maintenance cantilever of tower crane hangs, the maintenance cantilever of tower crane hangs, and it comprises that winch, pulley, cantilever hang mount pad, strut, cantilever beam, pulley casing, pulley yoke, cover of wedge, wedge, bearing pin, bearing pin, spring cotter, roller, travelling wheel and cantilever hung mount pad be fixed on the equilibrium arm; Pulley is contained in cantilever and hangs in the mount pad, connects with bearing pin, plugs spring cotter; Winch is installed in cantilever and hangs on the mount pad; Strut is installed in cantilever and hangs in the mount pad; Pulley is installed in the strut, connects with bearing pin, plugs spring cotter; Earlier two rollers are installed in strut by on two following positions, connect, plug spring cotter with bearing pin; Cantilever beam is installed on the roller of strut; 2 rollers are installed in two positions above the strut, connect, plug spring cotter, bearing pin is inserted in the strut, plug spring cotter, cantilever beam is not slided on strut with bearing pin; Four travelling wheels are installed on the pulley casing; The pulley casing that four travelling wheels have been installed is installed on the cantilever beam; Pulley is installed on the pulley casing, connects with bearing pin 11, plugs spring cotter; , earlier pulley is installed on the pulley yoke, connect with bearing pin, plug spring cotter, again pulley yoke is installed on the pulley casing, connect with bearing pin, plug spring cotter; Steel rope in the winch is hung the mount pad middle pulley by cantilever, arrive the strut middle pulley again, arrive the pulley casing middle pulley again, arrive the pulley yoke middle pulley again, be fixed on the pulley casing with wedge and cover of wedge at last.
The utility model re-constructs the structural shape of cantilever beam, changes original fixed boom beam into cantilever beam and 4 synthetic movable boom beams of roller set, and cantilever is hung can both freedom 360 be rotated, and gives full play to the effect of its lifting.
