Embodiment
In order more clearly to understand above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.It should be noted that, in the situation that not conflicting, the application's embodiment and the feature in embodiment can combine mutually.
A lot of details have been set forth in the following description so that fully understand the present invention; but; the present invention can also adopt other to be different from other modes described here and implement, and therefore, protection scope of the present invention is not subject to the restriction of following public specific embodiment.
Fig. 1 and Fig. 2 show an embodiment of front handling mobile crane potential energy recycling system provided by the invention.The shown front handling mobile crane potential energy of this embodiment recycling system comprises vehicle frame 1, the jib basic segment 2 hinged with vehicle frame 1, collection utilizes front handling mobile crane jib potential energy, the elastic device between vehicle frame 1 and jib basic segment 2, and elastic device comprises, accumulation of energy oil cylinder 31, hydraulic oil pipe 32, transition block 33, reduction valve 331, one-way valve 332, relief valve 333 and accumulator 34.
This accumulation of energy oil cylinder---accumulator combination embodiment's elastic device, the fundamental diagram of its hydraulic system as shown in Figure 2, accumulation of energy oil cylinder---accumulator elastic device hydraulic system is closed type hydraulic system, on shared existing front handling mobile crane, give the variable displacement pump 334 of main system fuel feeding, when initial start-up system, variable displacement pump 334 is given system fuel feeding, from variable displacement pump 334 hydraulic oil source out, except giving main system P fuel feeding, part hydraulic oil is through reduction valve 331, one-way valve 332 enters accumulator 34, when accumulator 34 supercharging pressures reach the pressure of relief valve 333 settings, relief valve 333 is opened, system overflow, 333 safety effects of relief valve, now variable displacement pump 334 is no longer given potential energy recycling system fuel feeding, and only to main system P fuel feeding.When needs lifting arm support, in accumulator 34, the energy of storage discharges, and the piston rod of two accumulation of energy oil cylinders 31 stretches out lifting arm support, and auxiliary pitching oil cylinder provides lifting force for jib; When needs bend down jib, the auxiliary pitching oil cylinder of accumulation of energy oil cylinder 31 provides support power, the piston rod of two accumulation of energy oil cylinders 31 is retracted under the effect of jib gravitational potential energy, the hydraulic oil of accumulation of energy oil cylinder rodless cavity is extruded, accumulator 34 is opened topping up, absorb this part stored energy in accumulator 34, when jib needs lifting again, this part energy being stored discharges the lifting for accumulation of energy oil cylinder 31 again.
The working principle of front handling mobile crane potential energy recycling system embodiment of the present invention shown in Fig. 1, Fig. 2 is:
When pitching oil cylinder is retracted, jib bends down, elastic device between vehicle frame 1 and jib basic segment 2 decomposes the pressure of a part of jib to pitching oil cylinder, auxiliary pitching oil cylinder provides the support force of a part to jib, and the gravitational potential energy that the jib that decomposition is born bends down stores; Because elastic device provides supplemental support power to jib, so the support force that pitching oil cylinder need to provide load obtained reduction, and then the meter out on pitching oil cylinder oil circuit reduces, and system heating reduces; And need again steeve while mentioning load when jib, elastic device discharges the potential energy of storage when jib bends down, auxiliary pitching oil cylinder lifting arm support, so the required lifting force providing of pitching oil cylinder is reduced, and reaches energy-conservation effect.
Fig. 3 shows another embodiment of front handling mobile crane potential energy recycling system of the present invention.When different from the accumulation of energy oil cylinder-accumulator technical side scheme shown in Fig. 1, Fig. 2, the present embodiment Elastic device adopts is mounted in the spring 4 between vehicle frame 1 and jib basic segment 2, directly utilizes spring 4 to store and discharge the gravitational potential energy of jib.When jib bends down, spring 4 provides supplemental support power and is depressed, and the elastic potential energy that the gravitational potential energy of jib is converted into spring 4 stores, when needs lifting arm support, the elastic potential energy of spring 4 storages discharges and assists pitching oil cylinder that lifting force is provided, the lifting of auxiliary jib.Elastic device adopts the front handling mobile crane potential energy recycling system easy realization simple in structure of spring, transformation of energy mode is the conversion of gravitational potential energy and elastic potential energy, Conversion of Energy loss is little, selects suitable spring rate, can farthest recycle gravitational potential energy.
In sum, front handling mobile crane potential energy recycling system provided by the invention, simple in structure easy to implement, realized recovery and utilization to front lift heavy power potential energy, reach the effect that makes front handling mobile crane energy saving of system; The energy being slatterned by Hydraulic System Fever during due to recovery front handling mobile crane jib nutation, has reduced the heating of hydraulic system, has improved performance and the operating life of hydraulic system.The present invention also provides a kind of front handling mobile crane.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
