Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figures 1 to 3, according to embodiments of the invention, Vehicular concrete pump truck comprises driving engine 1, electric power system, feed system, distribution system and stirring system, and feed system is connected with driving engine 1, and under the driving of driving engine 1 pumping material; Distribution system is connected with electric power system, and distributes material under the driving of electric power system; Stirring system is connected with electric power system, and stirs material under the driving of electric power system.This Vehicular concrete pump truck adopts dual power source to work simultaneously; utilize the feed system that driving engine supply load is larger; utilize distribution system and stirring system that electric power system supply load is lower, the pollution discharge rate of driving engine can be reduced like this, be more conducive to environmental protection; and the service life of driving engine can be extended; meanwhile, effectively utilize the power supply in building site, effectively reduce energy dissipation; improve energy saving, and improve the service life of Vehicular concrete pump truck.This Vehicular concrete pump truck adopts dual power source, and simultaneously for different loads provides power, reduce power demand, applicability is better.
The overall load power of electric power system is less than 40 kilowatts, the scope of the overall load power of distribution system is 10 kilowatts to 25 kilowatts, the scope of the overall load power of stirring system is 5 kilowatts to 14 kilowatts, and the scope of the overall load power of feed system is 70 kilowatts to 155 kilowatts.Distribution major part due to camp site is 40 kilowatts, and this cannot meet the total load requirements of Vehicular concrete pump truck usually, and thus the electric motor system many places of existing Vehicular concrete pump truck are in idle state, cannot be utilized effectively.And adopt the Vehicular concrete pump truck of the present embodiment, drive distribution system and stirring system by electric power system, the overall load of electric power system is no more than 40 kilowatts, and this makes the power supply of camp site to be utilized effectively, and decreases the discharge of pollution.
By the research of the pumping power to Vehicular concrete pump truck, find that pumping dynamicload is divided into following three parts:
Part I is pumping load, and also i.e. feeding load, is the job load by the feeding of master cylinder 3 crank motion, and master cylinder 3 is driven by main oil pump 6 fuel feeding, and its consumed power is comparatively large, is generally 70 to 155 kilowatts;
Part II distributes load, and also namely material distributes, and is the job load being distributed material by oscillating oil cylinder crank motion, this oscillating oil cylinder distributes oil cylinder 10 exactly in the present embodiment, distribute oil cylinder 10 to be driven by constant pressure pump fuel feeding, its consumed power is little, is generally 15.7 kilowatts to the maximum;
Part III stirs load and cooling load, stir load and namely stir material by stirring motor 11, to be cooling load be exactly carries out by water pump and cooling motor etc. the job load that cools, is driven by gear type pump 25 fuel feeding, consumed power is less, is generally 9.3 kilowatts to the maximum.
The overall power requirement of Vehicular concrete pump truck is between 95 to 180 kilowatts.
And existing building site electric power is supplied as about 40 kilowatts external operation power supplys substantially.This electric power supply is difficult to the demand meeting concrete pump truck, and this makes the electrical motor of double dynamical concrete pump truck perform practically no function.
In the present invention, the load of Vehicular concrete pump truck is divided into two parts, respectively by different power source, existing building site electric power can be utilized effectively, economize energy, decreasing pollution discharges.Feeding loading section still adopts diesel engine, and output rating is at about 110 kilowatts.Other non-feeding loads adopt electrical motor, and output rating is less than 30 kilowatts.In addition cancel original driving engine and carry fan cooling system and generator system, adopt the motor fan cooling system of external source and configuration thereof, this part power is about 10 kilowatts.
