In prior art, by lifting running gear mobile position controlling suspension hook on arm, and undertaken feeding and discharging by releasing or regain rope.But, because lifting running gear and suspension hook are on a vertical line, the application force of arm is also concentrated on to the region of lifting by crane running gear and being positioned at, larger to the by-local forces of arm, easily cause wearing and tearing, and may rotate in material process of rising or falling, cause fluctuation of service, easily cause danger.
Utility model content
The utility model proposes a kind of change triangle start lifting rope rope tower crane, reduce the application force to arm local, and avoid material rotation to cause rope to be wound around.
The one that the utility model proposes becomes triangle start lifting rope rope tower crane, comprising: base, tower body, turntable, arm, lifting running gear, equilibrium arm, suspension hook, counterweight, counterweight running gear, pinnacle of a pagoda, bracket, baffle plate, rope; Wherein, tower body, is fixed on base; Pinnacle of a pagoda, is located at tower body top; Turntable, between tower body and pinnacle of a pagoda; The turntable left and right sides is fixed with arm and equilibrium arm; Fixed pulley, is positioned at arm one end away from tower body; Lifting running gear, is arranged on and hangs wall one end near tower body, and can move to fixed pulley along length of boom direction; Movable pulley, be arranged between lifting running gear and fixed pulley by rope, rope one end is fixed on lifting running gear, and the other end is connected back the active rotating disk on lifting running gear successively with movable pulley through fixed pulley, can regain under the driving of driving disc spacing pressing or release rope; Suspension hook is arranged on the below of movable pulley; The movable counterweight running gear installed with counterweight on equilibrium arm.
Preferably, lifting running gear can be arranged in arm, and lifting running gear bottom surface is provided with roller, is provided with slide rail in arm.
Preferably, during feeding, lifting running gear first moves to assigned address, then releases rope; When getting material, first mobile lifting running gear is to initial position, then regains rope.
Preferably, movable pulley is two that are arranged side by side, and diameter is identical.
In the utility model, at arm, one fixed pulley is set away from one end of tower body, lifting running gear is arranged on arm one end near tower body, and can move along length of boom direction to fixed pulley, suspension hook connects a movable pulley, rope one end is fixed on lifting running gear, and the other end is connected back the active rotating disk on lifting running gear successively with movable pulley through fixed pulley; Fixed pulley, movable pulley and lifting running gear form a triangle, and weight of material is evenly assigned on fixed pulley and lifting running gear, can not produce comparatively noticeable effort to arm local; Further, the rope of shape distribution triangular in shape can be avoided rotating under material drives being intertwined.
Accompanying drawing explanation
Fig. 1 is that the one that the utility model embodiment 1 proposes becomes triangle start lifting rope rope tower type crane structure figure.
Reference numeral:
1, base; 2, tower body; 3, turntable; 4, arm; 5, lifting running gear; 6, equilibrium arm; 7, suspension hook; 8, counterweight; 9, counterweight running gear; 10, pinnacle of a pagoda; 11, movable pulley; 12, fixed pulley; 13, rope.
Detailed description of the invention
The utility model embodiment 1 proposes a kind of change triangle start lifting rope rope tower crane, for transporting material 14, as shown in Figure 1, comprising: base 1, tower body 2, turntable 3, arm 4, lifting running gear 5, equilibrium arm 6, suspension hook 7, counterweight 8, counterweight running gear 9, pinnacle of a pagoda 10, movable pulley 11, fixed pulley, rope 13.Wherein, tower body 2, is fixed on base 1; Pinnacle of a pagoda 10, is located at tower body 2 top; Turntable 3, between tower body 2 and pinnacle of a pagoda 10; Turntable 3 left and right sides is fixed with arm 4 and equilibrium arm 6; Fixed pulley 12, is positioned at arm 4 one end away from tower body 2; Lifting running gear 5, be arranged on and hang, 4 near one end of tower body 3, and can move along length of boom direction to fixed pulley 12; Movable pulley 11, be arranged between lifting running gear 5 and fixed pulley 12 by rope 13, rope 13 one end is fixed on lifting running gear 5, the other end is connected back the active rotating disk on lifting running gear 5 successively with movable pulley 11 through fixed pulley 12, can regain under the driving of driving disc spacing pressing or release rope 13; Suspension hook 7 is arranged on the below of movable pulley 11; The movable counterweight running gear 9 installed with counterweight 8 on equilibrium arm 6, for moving along equilibrium arm 6 direction under the driving of motor, to keep balance in arm 4 working process.
In working process, by the mobile lifting position of running gear 5 on arm 4, the drop point of suspension hook 7 can be controlled, specifically, lifting running gear 5, fixed pulley 12 and movable pulley 11 form equicrural triangle, and the drop point of movable pulley 11 is the upright position of lifting running gear 5 and fixed pulley 12 line mid point.Then, lifting running gear 5 is fixed, carry out folding and unfolding rope 13 by active rotating disk in lifting running gear 5 and carry out feeding discharging.Because fixed pulley, movable pulley and lifting running gear form a triangle, weight of material is evenly assigned on fixed pulley and lifting running gear, can not produce comparatively noticeable effort to arm local; Further, the rope of shape distribution triangular in shape can be avoided rotating under material drives being intertwined.
Preferably, lifting running gear 5 can be arranged in arm 4, and lifting running gear 5 bottom surface is provided with roller, is provided with slide rail in arm 4.
Preferably, during feeding, lifting running gear 5 first moves to assigned address, then releases rope; When getting material, first mobile lifting running gear 5 is to initial position, then regains rope.
Preferably, movable pulley is two that are arranged side by side, and diameter is identical.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
