Abstract
The utility model relates to a dual-energy system of a mobile crane and a mobile crane. The dual-energy system comprises a storage battery set, a generator, a solar charging device, and a crane electric appliance element. The storage battery set, the generator, and the solar charging device are arranged in parallel. When operating, the generator charges the storage battery set and supplies power to the crane electric appliance element. When the generator does not operate, the solar charging device charges the storage battery set and supplies power to the crane electric appliance element. On the basis that the mobile crane uses a generator as main energy, the dual-energy system adds the solar charging device in order to charge the storage battery set when the electric energy of the mobile crane is insufficient. The dual-energy system satisfies a power requirement of a standby device, compensates the power of the storage battery set, provides new energy for the mobile crane, saves fuel consumption, and improves use economical efficiency.
Description
Technical field
The utility model relates to engineering machinery field, is specifically related to a kind of Dual-energy source system of mobilecrane and the mobilecrane with this Dual-energy source system.
Background technology
Mobilecrane refers to the crane that complete machine can move freely, and carries out the installment work of the outdoor equipments such as petrochemical industry, high ferro, wind-powered electricity generation, mainly relies on engine as power source, and hydraulic system and the control system energy are provided.The electric energy that control system needs is by engine driven generators, and direct driving control system element after rectifying and wave-filtering, also to charge in batteries.Now electric power system is all provided by engine.The storage battery that mobilecrane uses is mainly used in diesel engine starting, flashing relay (simultaneously opening direction indicator lamp all around for clutch), Engine ECU (data record, storage etc.), GPS(Geographic mapping, information and uploads etc.) etc. electric equipment power supply and illumination etc., when being charging, operation principle utilize outside electric energy to make inner active material regeneration, electrical power storage, be chemical energy, in the time of need to discharging, again chemical energy be converted to electric energy output.
But mobilecrane is divided into the chassis two kinds of operating modes of operation of travelling and get on the bus, when travel in chassis, generator can be endlessly to charge in batteries, while getting on the bus operation, not generally continuous, pilot engine, operation, flame-out work period be short, while there is no job task for capable of saving fuel oil, driver can not stop working immediately, and generator is short to the charging interval of control system, and starting often, power consumption is large, causes discharged or defective battery serious.
