- Oct 18, 2017-

The container side loader is characterized in that the scissors support device comprises an external scissor holder, inside scissors frame, hinge axis, fixed plate, lifting cylinder and tilt swing arm device, the upper end of the vehicle chassis are respectively provided with inner scissors frame and outside scissor frame, the inner scissors frame and the outer scissor frame are hinged by hinge axis, Container Side Loader and the lower end of the inner scissors frame is hinged with the connecting rod respectively. The connecting rod ends are connected with the vehicle chassis, and the lower end of the lifting cylinder is hinged with the car chassis, Container Side Loader the upper end is hinged with the top of the inner scissor frame, and the bottom of the scissors frame is hinged with the front part of the vehicle chassis, and the upper end is hinged with the rear of the tilting arm device and the conveying platform, and the tilting arm device comprises a folded arm cylinder and a tilting swinging arm. The upper end of the tilting arm is connected with the transmitting platform, the lower end is hinged with the outer scissors frame, Container Side Loader the lower end of the folded arm is hinged with the outer scissor frame, the upper end is hinged with the tilting arm, and has the advantages of novel structure, high general performance, fast docking and high transportation efficiency.

The container loader is the special ground equipment of the air cargo transportation industry, which can effectively improve the high fuel consumption and large discharge of the traditional diesel container loader. In the actual working process of container loader, because of the change of container quality, accumulator State of Charge, Container Side Loader SOC and temperature, the operation load of the loader, the initial SOC of the accumulator and the initial temperature of the accumulator are all uncertain. Therefore, the control strategy should meet the performance requirements of loader under different operating conditions, Container Side Loader and realize the goal of energy saving and discharge reduction. The main research contents of this paper are as follows: ① analyzes the actual working characteristics of the container loader, determines the working cycle diagram of the loader, Container Side Loader establishes the engine numerical model of the container loader, the motor/generator efficiency model, the battery charge and discharge model and the temperature rise model of the accumulator. The control logic and control strategy of the loader based on the rules are designed according to the characteristics of the engine ②, the efficiency of the motor and the operating conditions of the loader. Through the orthogonal experiment design method, based on the minimum fuel consumption in a working cycle, the control parameters of the loader are optimized, the parameters are the charge torque limit, Container Side Loader the control torque of the engine when charging, the torque limit of the spark, the control torque of the engine and the high SOC threshold of the battery. ③ using Simulink to establish the fuel economy simulation model of loader, and simulate the operation of loader under different operating conditions, the results show that: the loader at different load, different battery initial temperature operating, for different battery initial SOC, At the end of the working condition, Container Side Loader the battery SOC is within reasonable range, and when the initial SOC value of the battery is within the commonly used range, the battery soc reaches the load balance at the end of the working condition, and the engine and the motor are mostly running in the high efficiency area when the load is run. The container loader equipped with energy recovery system is less than the equivalent fuel consumption under different load and different battery initial soc, Container Side Loader and the fuel saving rate is more than 8%. The fuel consumption of hybrid power loaders with energy recovery systems has been reduced by more than 21% compared to traditional loaders. ④ the temperature rise of accumulator under different working conditions was studied. The simulation results show that the end temperature of the accumulator is not more than 45.1 ℃ in the reasonable temperature range when the accumulator is working under different load, different initial temperature and different initial soc, and the battery temperature is higher when the initial SOC is higher or lower.
