Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
As shown in Figure 1, 2, the present invention provides a kind of anti-sway multifunctional hanging tool of lifting posture adjustment, which is characterized in that described to hang
Tool includes swing mechanism 1, hanger 2, rope traction and parallel-connection mechanism and gyroscope 6, and the rope traction and parallel-connection mechanism includes controller, rope
Rope enabled device, wire drive, Universal pulley 3 and rope 4.
The upper end of swing mechanism 1 is connect with tower crane, and lower end is connect with hanger 2, can drive the 360 ° of models in the horizontal direction of hanger 2
It does in enclosing and rotates at any angle；Hanger 2 has n bracket, symmetrically opens at umbrella shape, is hollow structure, the controller, rope
Enabled device and wire drive are located at the inside of hanger 2, and the Universal pulley 3 has 2n, and two one group is symmetrically distributed in
The stent ends of hanger 2, the rope 4 has 2n root, nonelastic, is controlled by rope release device, wears from the stent ends of hanger
Out, after Universal pulley 3, prefabricated components 5 are connected；The gyroscope 6 is angular movement detection device, is arranged on prefabricated components 5,
It wirelessly communicates and connects with the controller of rope traction and parallel-connection mechanism, acquire the angular move-ment signals of prefabricated components 5 in real time, and be sent to control
Device processed；Controller receives the angular move-ment signals of gyroscope transmission, and controls rope enabled device and wire drive makes phase
The movement answered；Rope enabled device controls the enabled of rope 4, so that the input quantity of rope 4 is controlled, wire drive control
The length of rope 4.
The angular move-ment signals and lift detailed location information that the rope traction and parallel-connection mechanism is detected according to gyroscope 6, pass through
Change the input quantity of rope 4 and the length of investment rope 4, is able to achieve the six-freedom motion of prefabricated components 5.And according to movement
It learns and determines mechanism, the quantity for the swing for avoiding prefabricated components 5, the rope 4 of the suspender should be greater than number of degrees of freedom, therefore n >=4, n are got over
Greatly, the device stability is better, adjusts finer, n=6 in the present embodiment, i.e., there are six brackets, Universal pulley 3 six for hanger 2
Group, rope have 12.
As shown in figure 3, a kind of lifting control method of the anti-sway multifunctional hanging tool of posture adjustment, the control method are as follows: control
The angular move-ment signals and lifting detailed location information, generation control instruction that device is fed back according to gyroscope 6 send the enabled dress of rope to
It sets and wire drive changes the appearance of prefabricated components 5 under rope enabled device and the synergistic effect of wire drive
State, the new angular move-ment signals that gyroscope 6 will test feed back to controller, loop back and forth like this, until prefabricated components 5 reach
Hoisting Position.
The workflow of the above-mentioned anti-sway multifunctional hanging tool of lifting posture adjustment is as follows:
All ropes 4 are hinged with prefabricated components 5, crane is operated, is transported to prefabricated components 5 by tower crane
Above Hoisting Position, hanger 2 is driven to rotate in the horizontal direction by swing mechanism 1 substantially uniform with lifting direction；Further
According to lifting detailed location information and gyroscope 6 transmit angular move-ment signals, rope traction and parallel-connection mechanism is first by prefabricated components 5
Centre of gravity adjustment is to horizontal position, then controls the movement and rotation of 5 horizontal direction of prefabricated components, and gyroscope 6 believes new angular movement
Number rope traction and parallel-connection mechanism is fed back to, rope traction and parallel-connection mechanism adjusts prefabricated components 5 again, until prefabricated components 5 reach
Hoisting Position.Rope traction and parallel-connection mechanism can change the input quantity of rope 4 by rope enabled device, pass through wire drive
Change the length of rope 4, thus change the spatial distribution of rope 4 and the direction of restraining force, to adjust the center of gravity of prefabricated components 5,
And realize the posture adjustment of the six degree of freedom of prefabricated components 5.
The quantity of the rope 4 of the suspender is greater than number of degrees of freedom, belongs to kinematics and determines mechanism, can be to avoid prefabricated components 5
Swing；But there are a variety of interference during lifting, if unbalance during posture adjustment, it would still be possible to swing, a side
The face suspender can increase the input quantity of rope 4 by rope traction and parallel-connection mechanism, increase restraining force, make the qualitative enhancing of stable gravity center；
On the other hand the suspender constantly feeds back angular move-ment signals, first adjusts the center of gravity of prefabricated components 5 to horizontal position, can adjust weight rapidly
The heart, to avoid the swing of prefabricated components 5；Therefore the suspender can be actively anti-sway, and takes into account posture adjustment and anti-sway.
Explain why rope traction and parallel-connection mechanism is able to achieve pair with the kinetic model of Fig. 4 rope traction and parallel-connection mechanism below
The posture adjustment of component and anti-sway.If fixed coordinate system is O-XYZ, reference point P is the geometric center of prefabricated components 5, rope 4 and pulley
3 tie point is Bi, PiFor the hinge centres that rope 4 is connected with prefabricated components 5, r is the mass center of prefabricated components 5 relative to ginseng
The position vector of examination point P, feAnd MeThe external force not considered including gravity and the moment of face being respectively applied on reference point P.
Ifli=∣ Li∣,ui=Li/li, tiFor the pulling force of i-th rope, which generates one and acts on prefabricated components
Pulling force T on 5i=tiui, and
When rope traction and parallel-connection mechanism moves, the general movement of Theory of free rigid body can be regarded as.Being gained knowledge by Theory of free rigid body power can
It releases rope 4 and drives kinetics equation of the prefabricated components 5 relative to end effector reference point P:
Had according to Newton's equation:
Had according to Eulerian equation:
Wherein m represents the quality of prefabricated components 5, and g is acceleration of gravity, and v, w respectively represent speed and the angle of prefabricated components 5
Speed,Respectively represent the acceleration and angular acceleration of prefabricated components 5.
Since prefabricated components 5 are mostly the relatively regular cuboid of shape, mass center is overlapped with reference point P, i.e. r=0, equation
It can simplify are as follows:
In local coordinate system, the inertial matrix of load is I ', and the inertial matrix I in global coordinate system is
I=RI'RT
R is local coordinate system P-XpYpZpThe transformation matrix of opposite global coordinate system O-XYZ, if local coordinate system P-XpYpZp
It is respectively γ, β, α relative to the X-axis of global coordinate system O-XYZ, Y-axis, the rotation angle of Z axis, then:
Being write as matrix form has
Wherein
F=JTT
Fe=[fe Me]T
G=[0 0 mg 00 0]
Wherein, E3For three rank unit matrixs, T is the set of rope tension,The respectively mobile acceleration of prefabricated components 5
Set, the set of speed and angular speed with angular acceleration, subscript m=2n are the quantity of rope 4, and n is the bracket number of hanger 2
Amount.
It is apparent from by the kinetic model, prefabricated components 5 are controlled by the angular speed w that gyroscope 6 measures, and make inertia, external force, rope
The gravity balance of prefabricated components 5 and posture adjustment are able to maintain under the collective effect of pulling force and gravity, therefore rope traction and parallel-connection mechanism can be simultaneous
It cares for the posture adjustment of prefabricated components 5 and anti-sway.
In summary, by a kind of above-mentioned anti-sway multifunctional hanging tool of lifting posture adjustment and its control method, have following
The utility model has the advantages that
(1) device can realize the pose adjustment of prefabricated components quickly, accurately, automatically, by lifting by semi-artificial adjustment turn
