Description
Technical field
The present invention relates to container in hoisting status field, more particularly to a kind of container crane and its stabilizer.
Background technology
At present, container crane is in operation process, due to the effect of the load such as horizontal inertial force and wind-force, container
Suspender will produce in vertical plane and oscillate and produced 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 swing is declined rapidly
Subtract, allow container spreader to return to inactive state within the time as short as possible（Equilbrium position）Or the amplitude of oscillation is reduced to allowed band
It is interior, so as to improve operating efficiency.Existing countries in the world are to the performance requirement of sling anti-sway device, lift by crane liftoff 10m, dolly 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 protection device disclosed in the B of Chinese patent literature CN 104326367,
Including damper, mobile pulley, fixed block, slideway, rear crossbeam structure, steel wire rope, described rear crossbeam structure is fixed with resistance
Buddhist nun's device bearing；The damper bearing is hinged on the axle 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 the first described fixing axle；The rear crossbeam structure lower left is also associated with
Fixed block；Described hoist rope coils through mobile pulley and fixed block.By the use of damper viscous damping as
Working media, power is provided without the external world, without energy expenditure, while serving the dual of fixed support pulley and nacelle protection
Effect；It is simple in construction, good economy performance, the characteristics of with energy-saving and environmental protection.But the damper on traditional container crane is only capable of
To waving relatively into row buffering between suspender and door frame, it is impossible to which row buffering is entered in the swing to suspender itself, causes suspender itself
The problem of being waved there are still small size high frequency, container still can high frequency wave.
The content of the invention
The present invention is intended to provide a kind of stabilizer for reducing suspender itself rocking tendency, is used while additionally providing one kind
The container crane of the stabilizer.
In order to solve the above technical problems, the technical scheme of stabilizer is as follows in the present invention：

In the damper on suspender, damping wheel can be rotated relative to trolley frame around horizontal linear direction.
Damping wheel is sprocket wheel, and traction body includes be engaged the chain segment of cooperation with damping wheel and is connected to the of chain segment one end
One length of cable, the second length of cable for being connected to the chain segment other end.
The axis of damping wheel and the axis of reel are parallel to each other, and fixed pulley and movable pulley are each own a pair, dynamic with centering two
Pulley is symmetrical on damping wheel, symmetrical on reel with the fixed pulley of centering two.
Define reel, fixed pulley, movable pulley, damping wheel and traction body composition to subtract and shakes unit, subtract and shake unit and there are two, two subtract
Shake unit symmetrical in suspender long side direction.
Damper is three-in-one reducing motor, and two subtract the damper for shaking the relatively independent setting of unit connection.
The technical scheme of container crane is as follows in the present invention：
Container crane, including door frame and the wheeling mechanism that sets thereon, wheeling mechanism include trolley frame, reel
And suspender, the flexible and linear traction body of winding connection on reel, traction body is located on suspender from pile warp after reel extraction
Movable pulley, the damping wheel on suspender and the fixed pulley on trolley frame and be fixed on reel or trolley frame, damping wheel
Cooperation or frictional fit are engaged with traction body or occlusion coordinates, the damper on suspender is connected with damping wheel, hinders
Buddhist nun's wheel can be rotated relative to trolley frame around horizontal linear direction.
Damping wheel is sprocket wheel, and traction body includes be engaged the chain segment of cooperation with damping wheel and is connected to the of chain segment one end
One length of cable, the second length of cable for being connected to the chain segment other end.
The axis of damping wheel and the axis of reel are parallel to each other, and fixed pulley and movable pulley are each own a pair, dynamic with centering two
Pulley is symmetrical on damping wheel, symmetrical on reel with the fixed pulley of centering two.
Define reel, fixed pulley, movable pulley, damping wheel and traction body composition to subtract and shakes unit, subtract and shake unit and there are two, two subtract
Shake unit symmetrical in suspender long side direction.
Damper is three-in-one reducing motor, and two subtract the damper for shaking the relatively independent setting of unit connection.
The beneficial effects of the invention are as follows：
When damping wheel is damped device limitation and damping rotary, impact when container crane can be started and shut down by damping wheel
The impact force action that power traction body is received is to damper, to absorb this part of impact force by damper, and because of damper
It is located at damping wheel on suspender, so that waving for available buffer suspender itself, reduces suspender itself rocking tendency.
Brief description of the drawings
Fig. 1 is the structural representation of the stabilizer of crane in the present invention.
Embodiment
Describe the present invention in detail below with reference to accompanying drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case of, the embodiment in the present invention and the feature in embodiment can be mutually combined.
The embodiment of container crane in the present invention：The dolly that the container crane is mainly set by door frame and thereon
Mechanism is constituted.Door frame uses existing portal support or single-arm shift bracket.Trolley body is by trolley body and stabilizer group again
Into.
Stabilizer symmetrically arranged two subtracts on suspender and its long side and shakes unit and constitute.Subtract and shake unit including reel 1, volume
The flexible and linear traction body of winding connection on cylinder 1, traction body be located at from pile warp after the extraction of reel 1 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 is with leading
Draw body engagement to coordinate or frictional fit or occlusion cooperation, the damper on suspender, damping wheel are connected with damping wheel 5
