Description
Technical Field
The utility model relates to the technical field of aviation ground equipment, in particular to a double-power container cargo loader for an airport.
Background
The cargo loader is an indispensable large-scale, special self-running mechanical device for the aviation cargo transportation industry, and the main function of the device is to convey the aviation standard container or the cargo board cargo from the ground to the aircraft cargo hold, or to discharge the aviation standard container or the cargo board cargo from the aircraft cargo hold to the ground, and is a device which is necessary to be equipped in civil airports, and the cargo loader is mainly classified into 7 ton type, 14 ton type, 20 ton type, 27 ton type and 35 ton type according to the maximum allowable loading quality.
The working characteristics of the cargo loader are as follows:
the use condition of the cargo loader in the airport special vehicle is special, and the equipment has two conditions in the operation process:
(1) and (3) traveling: the equipment is in a running state from a parking space to a cargo compartment door of the aircraft;
(2) loading: the equipment is stopped at the cargo compartment door of the aircraft, the support is put down, the cargo of the container or the container plate is loaded and unloaded, the equipment is motionless at the moment, and only the lifting platform works.
The actual operation condition of the container cargo loader for docking one aircraft is as follows: the loading operation is carried out 90% of the time, 10% of the time is in driving, the working time of the next flight is normally about 1 hour, and the working time of the next transport flight is about 2-2.5 hours. Because the running speed of the container cargo loader is lower, the highest running speed is 11 km/h, and the container cargo loader in a standby state is parked in a special vehicle parking area near a machine position.
The power of the existing cargo loader comes from a diesel engine, the diesel engine power of the 7-ton cargo loader is 75kW, the diesel engine power of the 14-ton cargo loader is 105kW, and the average oil consumption per hour is about 10 liters, so that the generated diesel engine tail gas contains 456g of CO, 150g of CH+NOX and 12g of PM (particulate matters). Because the container cargo loader has no cab, the operation desk is arranged on the bridge platform, and the diesel engine and the exhaust outlet thereof are arranged below the bridge platform, the tail gas pollution of the diesel engine directly affects the health of operators, and particularly, when in loading operation, the vehicle is motionless, the tail gas of the diesel engine is directly discharged nearby the operators, and the tail gas pollution of the operator to the vehicle is seriously affected; meanwhile, the tail gas can also enter the cargo hold of the aircraft and even enter the cabin of the aircraft to pollute the air of the cabin, so the tail gas pollution of the cargo loader is an urgent problem to be solved in special equipment of the airport.
In order to solve the problem of diesel engine pollution, many manufacturers use battery packs as power to purely electric loaders. But it is not enough: (1) the battery is long-lived, the lead-acid power battery used under the working condition needs to be replaced integrally in two years, the cost is about 15 ten thousand, the battery is required to be replaced integrally in five years, the cost is about 40 ten thousand, and the electricity cost is cheaper than the oil cost, but the purchase cost and the battery maintenance cost of the battery are replaced every two years, the running cost is always equal, namely the battery is environment-friendly but does not save money; (2) the safety of batteries, especially those of the "lithium batteries" type, is also at risk, and problems with batteries and the like are faced; (3) because the position of the vehicle for placing the battery is not too many, the capacity of the battery cannot be matched much, so that the endurance mileage of the pure electric container cargo loader is shorter, namely more than ten kilometers, and when the container cargo loader needs maintenance or overhaul, the vehicle is difficult to start to a repair shop and can only be pulled back to the repair shop.
Although the pure electric loader has the above-mentioned disadvantages, the purchasing intention of the user for the vehicle is still strong, because the vehicle realizes zero pollution and zero emission during loading and unloading operation.
In order to solve the above technical problems, the present company applies for patent number 2010201824059 to the national institutes at 2010-5-27, and has the name: the utility model patent of a double-power device of a container lifting platform truck with an electric pump, which has the substantial defects that: during control, an experienced operator is required to operate, and when a motor or an engine is about to fail, the operator cannot perceive the motor or the engine, so that the operator cannot maintain equipment in time, and loading efficiency is affected.
