A kind of change triangle start lifting rope rope tower crane
Technical field
The present invention relates to hoisting crane technical field, relate in particular to a kind of change triangle start lifting rope rope tower crane.
Background technology
Hoisting crane refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods.The work characteristics of hoisting crane is to do intermittent exercise, and in a working cycle, the corresponding mechanism of the action such as feeding, migration, unloading is alternation.Elevator machinery used in bridge construction engineering, the difference according to its structure and performance, generally can be divided into small-sized weight-lifting equipment, bridge type crane tool and jib type hoisting crane, the large class of cable crane four.Small-sized weight-lifting equipment is as jack, air hoist, electric block, balance cucurbit (having another name called balance crane), winch etc.; Crane span structure class heavy-duty lifting machine is as beam crane etc.; Jib type hoisting crane is as stationary slewing crane, tower crane, car hosit, wheel-mounted crane, crawler crane etc.Wherein, tower crane is divided into fixedly tower crane and track driving tower crane.
In prior art, by lifting running gear mobile position of controlling suspension hook on arm, and rope is feeded and discharging by emitting or regaining.Yet, owing to lifting by crane running gear and suspension hook on a vertical line, the application force of arm is also concentrated on to the region that lifting running gear is positioned at, by-local forces what to arm is larger, easily cause wearing and tearing, and in material process of rising or falling, may rotate, cause fluctuation of service, easily cause danger.
Summary of the invention
The present invention proposes a kind of change triangle start lifting rope rope tower crane, reduce the application force to arm part, and avoid material rotation to cause rope to be wound around.
A kind of change triangle start lifting rope rope tower crane that the present invention proposes, 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 away from one end of tower body; Lifting running gear, is arranged on and hangs wall near one end of tower body, and can to fixed pulley, move along length of boom direction; Movable pulley, by rope, be arranged between lifting running gear and fixed 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 through fixed pulley successively with movable pulley, can under the driving of driving disc spacing pressing, regain or emit rope; Suspension hook is arranged on the below of movable pulley; The movable counterweight running gear of installing 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 emits rope; When getting material, first move lifting running gear to initial position, then regain rope.
Preferably, movable pulley is two that are arranged side by side, and diameter is identical.
In the present invention, at arm, away from one end of tower body, one fixed pulley is set, lifting running gear is arranged on arm near one end of tower body, and can to fixed pulley, move along length of boom direction, on suspension hook, connect 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 through fixed pulley successively with movable 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 be to the larger application force of the local generation of arm; And the rope that shape triangular in shape distributes can be avoided rotating and being intertwined under material drives.
Accompanying drawing explanation
Fig. 1 is a kind of change triangle start lifting rope rope tower type crane structure figure that the embodiment of the present invention 1 proposes.
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.
The specific embodiment
The embodiment of the present invention 1 has proposed a kind of change triangle start lifting rope rope tower crane, be used 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 tops; Turntable 3, between tower body 2 and pinnacle of a pagoda 10; Turntable 3 left and right sides are fixed with arm 4 and equilibrium arm 6; Fixed pulley 12, is positioned at arm 4 away from one end of tower body 2; Lifting running gear 5, is arranged on and hangs, 4 one end near tower body 3, and can to fixed pulley 12, move along length of boom direction; Movable pulley 11, by rope 13, be arranged between lifting running gear 5 and fixed pulley 12, rope 13 one end are fixed on lifting running gear 5, the other end is connected back the active rotating disk on lifting running gear 5 through fixed pulley 12 successively with movable pulley 11, can under the driving of driving disc spacing pressing, regain or emit rope 13; Suspension hook 7 is arranged on the below of movable pulley 11; The movable counterweight running gear 9 of installing with counterweight 8 on equilibrium arm 6, for moving along equilibrium arm 6 directions under the driving of motor, to keep balance in arm 4 working processs.
In working process, by movement, lift by crane the position of running gear 5 on arm 4, can control the drop point of suspension hook 7, 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 points.Then, will lift by crane running gear 5 fixing, and by active rotating disk in lifting running gear 5, carry out folding and unfolding rope 13 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 be to the larger application force of the local generation of arm; And the rope that shape triangular in shape distributes can be avoided rotating and being intertwined under material drives.
Preferably, lifting running gear 5 can be arranged in arm 4, and lifting running gear 5 bottom surfaces are provided with roller, in arm 4, are provided with slide rail.
Preferably, during feeding, lifting running gear 5 first moves to assigned address, then emits rope; When getting material, first mobile lifting running gear 5 arrives initial position, then regains rope.
Preferably, movable pulley is two that are arranged side by side, and diameter is identical.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
