Description

Technical Field

[0001] The utility model belongs to the technical field of special vehicles for airports, and in particular relates to a working platform for an aircraft water cleaning vehicle. Background Art

[0002] Airport special vehicles, namely airport ground handling vehicles, include aircraft guide vehicles, passenger elevator vehicles, airport shuttle vehicles (remote parking positions), barrier-free boarding vehicles (remote parking positions), crew buses, conveyor belt vehicles, lift trucks, airport trains (luggage carts), lifting garbage trucks, ground power trucks, ground air conditioning trucks, ground air source trucks, sewage trucks, clean water trucks, aviation fuel trucks, aircraft cleaning trucks, airline catering trucks, de-icing trucks, aircraft tractors, etc.

[0003] Among them, the aircraft water tanker is a special ground vehicle for adding drinking water for passengers on the aircraft. The drinking water filling port of the aircraft is located in the belly of the aircraft, which is relatively high relative to the ground. When supplying water to the aircraft, a working platform is required. The operator stands on the working platform to connect the water pipe to the filling port of the belly of the aircraft. After searching CN212047938U, a working platform for an aircraft water tanker is disclosed, including a first support beam, a second support beam, a third support beam, a first column and a second column. The first column is installed on the side of the first support beam close to the rear of the vehicle, and the bottom of the second support beam away from the rear of the vehicle is connected to the first column in a dislocated manner; the second column is installed on the side of the second support beam close to the rear of the vehicle, and the bottom of the third support beam away from the rear of the vehicle is connected to the second column in a dislocated manner. The front end of the first column is not flush with the front end of the second support beam, and is connected in a dislocated manner. The space at the rear of the vehicle for designing and installing the working platform is limited. When the height of the step ladder is constant, the number of steps can be increased. When the operator adds water to the aircraft, he can choose the corresponding step ladder according to his height.

[0004] However, the inventors have discovered that this technical solution still has at least the following defects:

[0005] In the above device, the steps are arranged so that the operator can select the corresponding step according to his / her height to add water to the aircraft. However, each step of the steps is relatively narrow, and the standing area for the operator is small. It is not convenient for the operator to stand on the steps to add water. In addition, there is a height difference between adjacent steps of the steps. It is easy to be inconvenient for the operator to connect the water filling pipe to the filling port on the belly of the aircraft when standing on adjacent steps.

[0006] In view of this, the present utility model is proposed. Utility Model Content
