Background technology
On market, no matter existing loader is wheel loader or crawler-type loader, is all mainly with fuel engines for power source, and so not only oil consumption is big, and operating cost is high, and environment is also had very big pollution. When fuel engines works, external environment condition severe on building site makes the life-span of electromotor be greatly shortened, thus engine maintenance cost is also very big. Along with becoming increasingly conspicuous of the energy and environmental problem, electric loader is used to be possible not only to its operating cost is greatly decreased, it is achieved zero-emission, it is also possible to the maintenance cost of loader is greatly decreased.
Traditional electric loader, if it were not for direct battery power if it were not for AC power supplies is powered, it does not have the electric loader that a kind of alternating current/accumulator is dual-purpose. When remote suburb powers without electrical network, simple alternating current electric loader will be unable to operation; If when there being AC power supplies, simple accumulator loader also using accumulator, not only to carry out AC-to-DC electricity conversion, and efficiency reduces, and also substantially reduces battery life. Existing simple accumulator electric loader on market, under low speed, torque and overload capacity are little, often lead to operation effectiveness undesirable. Additionally, the feed cable of existing alternating current electric loader is to mop floor or erect on a high pole, such loader is inconvenient when operation, and also can wear and tear cable, brings potential safety hazard. Automatically cable drum is shunk, not only convenience attractive in appearance but also above-mentioned abrasion and safety problem can be reduced if adopting.
Utility model content
For above-mentioned existing electric loader Problems existing and deficiency, this utility model provides a kind of alternating current/accumulator dual-purpose electric loader.
The purpose of this utility model is realized in, including motor, car body, power set, work system, drive system, driver's cabin, radiator, described power set are AC power supplies power set and two groups of accumulator power set, and AC power supplies power set include automatically shrinking cable drum; Accumulator power set include accumulator box; Described radiator is arranged on car body and is positioned at after motor tail, and motor and drive system are linked together by shaft coupling, and are assemblied in the centre of car body; AC power supplies is connected with the triple line automatically shrinking cable drum being arranged on car body, automatically shrinks cable drumThreePhase outlet is connected with the three-phase end of incoming cables on converter; The positive and negative electrode outlet of accumulator box is connected with the positive and negative level input of the direct current on converter respectively; The power line of converter, data line are connected with the AC-to-DC electrical switch on driver's cabin and electric gas pedal respectively; The triple line of motor is connected with the three-phase leading-out terminal on converter; Described work system is linked together by pin and car body, and the tailstock of described loader arranges ballast box.
This utility model power set are AC power supplies power set and two groups of accumulator power set, solve the energy-provision way that traditional electric loader is single, namely can only by accumulator or AC power supplies can only be used. This utility model electric energy replaces fuel oil, it is possible to loader operating cost, environmentally safe are greatly decreased, and comparing fuel engines is power, more energy-conserving and environment-protective, and maintenance cost is also low; Two kinds of energy-provision way coexist, and not by environmental limitation, use convenient, select the energy-provision way being suitable for according to working environment.
