Description
Technical field
The present invention relates to container in hoisting status field more particularly to a kind of container cranes and its stabilizer.
Background technology
Currently, container crane is in operation process, due to the effect of the load such as horizontal inertial force and wind-force, container
Suspender will generate in vertical plane and oscillate and generated in horizontal plane torsional oscillation, to hanger twist lock and container angle
The precise alignment of accessory and the accurate stacking of container bring very big difficulty.The stabilizer of suspender is exactly that swing is made to decline rapidly
Subtract, container spreader is allowed to be restored to stationary state in the shortest possible time（Equilbrium position）Or the amplitude of oscillation is reduced to allowable range
It is interior, to improve operating efficiency.Existing countries in the world are to lift by crane liftoff 10m to the performance requirement of sling anti-sway device, trolley with
Normal speed is run, and after Brake stop in 6s, the swing-scanning control of suspender is within ± 100mm.Existing suspender subtracts the mode of shaking such as
A kind of Quayside container bridge crane damper formula nacelle protective device disclosed in 104326367 B of Chinese patent literature CN,
Including damper, mobile pulley, fixed pulley, slideway, rear crossbeam structure, steel wire rope, the rear crossbeam structure is fixed with resistance
Buddhist nun's device bearing；The damper bearing is hinged on the axis of damper；The piston rod head of the damper passes through oscillating bearing

It is connected with the first fixing axle；Mobile pulley is connected in first fixing axle；Crossbeam structure lower left is also associated with after described
Fixed pulley；The hoist rope coils through mobile pulley and fixed pulley.Using the viscous damping of damper as
Working media provides power without extraneous, without energy expenditure, while playing the dual of fixed support pulley and nacelle protection
Effect；Simple in structure, good economy performance has the characteristics that energy-saving and environmental protection.But the damper on traditional container crane is only capable of
Opposite between suspender and door frame being waved into row buffering, can not lead to suspender itself to the swing of suspender itself into row buffering
The problem of being waved there are still small size high frequency, container still can high frequency wave.

Damper is three-in-one decelerating motor, and two subtract and shake the damper that unit connects relatively independent setting.
The beneficial effects of the invention are as follows：
When damping wheel is damped device limitation and damping rotary, when container crane can be started and be shut down by damping wheel
The impact force action that impact force traction body is received is to damper, to absorb this part of impact force by damper, and because of resistance
Buddhist nun's device and damping wheel are located on suspender, so as to buffer waving for suspender itself, reduce suspender itself rocking tendency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the stabilizer of crane in the present invention.
Specific implementation mode
Come that the present invention will be described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case of, the feature in embodiment and embodiment in the present invention can be combined with each other.
The embodiment of container crane in the present invention：The trolley that the container crane is mainly arranged by door frame and thereon
Mechanism forms.Door frame uses existing portal support or single-arm shift bracket.Trolley body is by trolley body and stabilizer group again
At.
Stabilizer is subtracted by suspender and its long side symmetrically arranged two to be shaken unit and forms.Subtract that shake unit include reel 1, volume
Winding connects flexible and linear traction body on cylinder 1, after traction body self reel 1 is drawn pile warp be located at movable pulley on suspender,
Damping wheel 5 on suspender and the fixed pulley on trolley frame and be fixed on reel 1 or trolley frame, damping wheel 5 with lead
Draw body engagement cooperation or frictional fit or occlusion cooperation, the damper on suspender, damping wheel are sequentially connected on damping wheel 5
5 can rotate relative to trolley frame around horizontal linear direction.Damping wheel 5 is sprocket wheel, and traction body includes that cooperation is engaged with damping wheel 5
It chain segment 4 and is connected to first length of cable 2 of 4 one end of chain segment, is connected to the second length of cable 3 of 4 other end of chain segment.
The axis of damping wheel 5 and the axis of reel 1 are mutually parallel, fixed pulley and each own a pair of movable pulley, are closed with two movable pulley of centering
It is symmetrical in damping wheel 5, it is symmetrical about reel 1 with two fixed pulley of centering.Damper be three-in-one decelerating motor, two subtract shake unit company
Connect the damper of relatively independent setting.
The stabilizer is using sling upper rack as carrier, and steel cord ends are connected by transition apparatus with roller chain, chain
For item with the damping sprocket wheel on sling upper rack to engaging, the three-in-one decelerating motor of sprocket wheel postposition provides electromagnetic damping for sprocket wheel, should
Damping sprocket wheel also has the function of that suspender verts adjustment, meets the function that the revolution, Transverse needed for container hanging incline.For the short time
The rocking tendency of suspender is inside set to be reduced to tolerance interval, the carry out container heap that container door machine driver can be effectively
Code handling operation, the present invention provide a kind of sling upper rack using electromagnetic damping stabilizer, are consumed using swing mechanism action is subtracted
Suspender waves kinetic energy, to enable suspender to be rapidly achieved stable stationary state（Equilbrium position）, improve operating efficiency.
The operation principle of the stabilizer is：In the startup and braking process of container trolley, cause the first length of cable
2, the variation of 3 length of the second length of cable drives chain movement, with the swing of suspender and container, chain along sprocket wheel into
Row moves back and forth, and under the action of three-in-one decelerating motor, suspender carries out the reciprocating motion under big damping action, and realization, which subtracts, shakes work
With.It drives chain to carry out the reciprocating motion under big damping action using three-in-one damping motor, makes container spreader inertia kinetic energy
It is released, realizes that container spreader subtracts and shake, quickly recover to stationary state（Equilbrium position）Or the amplitude of oscillation is reduced to allowable range
It is interior.
The other embodiment of container crane in the present invention：Chain can also use the replacements such as synchronous belt, friction belt,
To realize engaging between traction body and damping wheel or frictional drive.
The embodiment of stabilizer in the present invention：Subtract in the structure of stabilizer and above-described embodiment in the present embodiment and shakes dress
The structure set is identical, therefore repeats no more.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, it will be understood by those of ordinary skill in the art that：It still may be used
With technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features；
And these modifications or replacements, various embodiments of the present invention technical solution that it does not separate the essence of the corresponding technical solution spirit and
Range.
