Oil-burning and electrically drive two-purpose forklift

Abstract

The oil-burning and electrically driven two-purpose forklift includes a frame, a power system, a gear box, a walking system, a hydraulic pump station, a hydraulic system, an operation system, an automatic control system, a cable reel, a reel oil motor and a walking oil motor. The power system includes one oil-burning engine and one AC motor; the hydraulic pump station includes one engine driven hydraulic pump station and one motor driven hydraulic pump station connected via a two-position three-way valve to the hydraulic system; the motor driven hydraulic pump station provides hydraulic oil to the reel oil motor and the walking oil motor, while the engine drives the input shaft of the gear box; and the automatic control system controls the forklift under the driving of the motor. The present invention can save fuel oil, reduce environmental pollution caused by oil burning tail gas and lower operation cost.

Description

technical field [0001] The invention relates to a forklift, in particular to a dual-purpose fuel and electric forklift which can be used alternately in fuel and electric driving modes. Background technique [0002] A forklift is a kind of engineering work vehicle, which can travel long distances on the road like a general vehicle. Handling and other operations. Forklifts in the prior art are driven by fuel, that is, the diesel engine drives the forklift to walk and the hydraulic system on the vehicle is driven by the diesel engine to make the forklift arm and other operating parts move. Fuel powered forklifts are the most commonly used type of forklifts in the prior art. Fuel drive has the advantages of high power and long driving distance, but during forklift operation, the forklift moves back and forth on a small site, and the exhaust gas and noise pollution of the fuel engine have a great impact on the staff on site. There are also forklifts driven by electricity in th...

AI Technical Summary

Problems solved by technology

Electric-driven forklifts do not have the problem of exhaust gas and noise pollution during forklift operation. However, due to the limited energy reserve of the battery and low power, it cannot drive the forklift for a long distance, nor can it provide a higher driving speed. , there is another prominent problem, that is, the pollution of waste batteries to the environment is very serious.

[0003] How to make forklifts can be driven by fuel oil during long-distance driving, and can be driven by electricity during operation, while avoiding environmental pollution caused by waste batteries. There is no technical solution that meets the above-mentioned requirements in the prior art.
