Abstract
The present invention relates to an energy-accumulation hydraulic power station of a hanger without electric cables, which comprises an upper frame of a container hanger, a lower frame of the hanger, a pulley block installed on the upper frame of the hanger, a hydraulic energy accumulation device installed on a hanger structure, a nitrogen bottle, an oil tank and an electric generator which are connected with the hydraulic energy accumulation device through a pipeline, a storage battery which is connected with the electric generator and is charged by the electric generator and an oil motor which is connected with the electric generator and is controlled through an electromagnetic valve so that electric energy is deposited and balanced. The energy-accumulation hydraulic power station without electric cable hangers of the present invention is driven by a hydraulic oil pump, and energy-accumulation power energy is formed. Except that energy is provided for all actions on the hangers, the energy-accumulation hydraulic power station can also provide power for a remote controller, an electromagnetic valve, a limit switch, a signal lamp, etc. The present invention solves the technical problems when the hanger without the electric cables carries out the operation actions by hydraulic drive and the energy problem of the hanger without the electric cables, and omits hanging cables of the hanger.
Description
This case is that application number is: 01113425.9 divide an application, the applying date is: 2001.6.13, denomination of invention is: hanger without electric cable.
Technical field
The present invention relates to container handling machinery, particularly a kind of energy-accumulating hydraulic power station of hanger without electric cable.
Background technology
One more than 60 meter long suspender cable all is housed between suspender on the existing container handling machinery and the machine tool, is used for the power and the signal transmission of each action of suspender.Suspender hoists, descends when loading and unloading operation, and the suspender cable is stored effectively by cable storage frame or tension cable reel.Owing to hoist with little vehicle speed constantly increases and when running into strong wind in the course of the work, the suspender cable is cisco unity malfunction usually, cable takes place when particularly adopting cable storage frame frame even hooked to break, and causes hoisting crane to shut down.On certain meaning, can the suspender cable normal operation be the key that can hoisting crane all weather operation.Moreover the vertical cable of suspender is worth expensive, if be damaged, changing vertical cable must increase expense.
If change the folding and unfolding that realizes cable by the suspender cable drum into, then on the dolly of hoisting crane, increase by a cover complicated mechanical electric apparatus, make dolly layout trouble, manufacturing cost increases.
Common container spreader generally overlaps hydraulic power station as propulsion source by a direct motor drive one, and electrical motor is generally 7.5kW, for to its power supply, the suspender cable must be housed, and the shortcoming of bringing thus also is unavoidable.
Summary of the invention
Task of the present invention provides a kind of energy-accumulating hydraulic power station of hanger without electric cable, and it has solved the hydraulically powered technical matters of each action of hanger without electric cable operation, makes it to form the energy-storage type power source.
Technical scheme of the present invention is as follows:
A kind of energy-accumulating hydraulic power station of hanger without electric cable, it comprises that container spreader is put on the shelf and the suspender undercarriage, and the assembly pulley of on suspender is put on the shelf, installing, it also comprises the hydraulic accumulator that is installed on the hanger structure, passes through pipeline bonded assembly nitrogen gas cylinder, fuel tank with hydraulic accumulator, electrical generator, be connected with electrical generator and by the storage battery of generator charging, and be connected oil motor, with savings and balance electric energy by solenoid control with electrical generator.
The energy-accumulating hydraulic power station of hanger without electric cable of the present invention is driven by hydraulic oil pump, forms the energy-storage type power source, except for the everything on the suspender provides the energy, also can be remote control equipment (RCE), electromagnetic valve, limit switch, signal lamp etc. power supply is provided.
In the present invention, the mechanical rotation of pulley is unbalanced at work in order to overcome suspender, when the mechanical energy of bringing when pulley is excessive, can absorb and store unnecessary energy; When the mechanical energy of bringing when pulley is not enough, can replenish the required energy of each actuating unit of suspender automatically again.
The invention solves the energy problem of hanger without electric cable, saved the vertical cable of suspender,, cable also can not occur and go out the frame problem, thereby improve the serviceability rate of hoisting crane greatly for obstacle has been cleared away in the operation of hoisting crane weather-proof.
Description of drawings
Fig. 1 is the main TV structure scheme drawing of a kind of hanger without electric cable energy-accumulating hydraulic power station of the present invention.
Fig. 2 is by plan structure scheme drawing shown in Figure 1.
Fig. 3 is the work scheme drawing of Fig. 1 hanger without electric cable energy-accumulating hydraulic power station.
The specific embodiment
Referring to Fig. 1 to Fig. 3, the present invention is a kind of energy-accumulating hydraulic power station of hanger without electric cable, and it comprises that container spreader puts 2 and suspender undercarriage (not shown) on the shelf, and the assembly pulley 3 of putting on the shelf and installing on 2 at suspender.On each pulley of assembly pulley 3 gear ring 4 is housed, puts on the shelf at suspender and gear 5 is housed on 2.Falk flexible coupling 6 is installed on gear wheel shaft 51.
Energy-accumulating hydraulic power station 9 of the present invention also comprises the hydraulic accumulator 91 that is installed on the hanger structure 1, pass through pipeline bonded assembly nitrogen gas cylinder 92 with hydraulic accumulator 91, fuel tank 93, electrical generator 94, be connected with electrical generator 94 and by electrical generator 94 storage batteries 95, and be connected oil motor 96 by solenoid control with electrical generator 94.
Energy-accumulating hydraulic power station 9 is connected with bidirectional ram formula hydraulic oil pump 8 by hydraulic circuit,, is made and forms an energy-storage type power source on the suspender to energy-accumulating hydraulic power station 9 intakes by bidirectional ram formula hydraulic oil pump 8.
Energy-accumulating hydraulic power station 9 is being equipped with the shock absorber 13 of shock-absorbing effect with the installation site of hanger structure 1.
The hydraulic oil of bidirectional ram formula hydraulic oil pump rotating output is to the oil-filled energy storage of leather bag type hydraulic accumulator, or to the oil-filled energy storage of piston hydraulic energy storage, used during in order to the suspender action.Just compress the nitrogen in the leather bag when hydraulic oil enters hydraulic accumulator, perhaps promote Piston Compression nitrogen, oil pressure is high more, and leather bag is compressed more little, and oil storage is also many more.If hydraulic efficiency pressure system needs hydraulic oil, can utilize electromagnetic valve that the hydraulic accumulator oil circuit is opened and discharge each mechanism of hydraulic oil driving suspender.When the hydraulic oil of bidirectional ram formula hydraulic oil pump output to the hydraulic accumulator pressurising during to q.s, pressure relay sends signal and makes the solenoid-driven oil motor, oil motor drives electrical generator again to battery charge.
Dexterously suspender is put on the shelf the rotation function of assembly pulley of idle running of the present invention is converted into hydraulic pressure energy and electric energy, and these energy are stored, and forms an energy-storage type power source on the suspender thereby make.This energy-storage type power source can not only drive the everything on the suspender, and can provide power supply for remote control equipment (RCE), electromagnetic valve, limit switch, signal lamp etc., saved the suspender cable, its modern design, original creation can be widely used in the container handling machinery industry.
