Problems solved by technology
In addition, due to the large size of the landing gear and the large wheel diameter of the tires, it sometimes hinders the activities of the maintenance personnel.
[0004] The working surface of the existing maintenance working ladder is small, so that the maintenance personnel need to frequently move the maintenance working ladder to adjust the position of the working surface when overhauling the wheel well, which reduces the efficiency of the maintenance work; at the same time, in order to maintain the maintenance work The stability of the ladder, its underframe occupies a large area, and it is easy to interfere with the landing gear of the aircraft

The invention provides an A330 series airplane wheel well and landing gear maintenance working ladder. The A330 series airplane wheel well and landing gear maintenance working ladder is large in working surface, safe and reliable, and aims to enable a worker to use the ladder to respectively approach the appropriate positions of a landing gear and a wheel well of an airplane, and when the airplaneis jacked up, the height of a working platform can be correspondingly adjusted without replacing the ladder. In addition, a pulling railing is arranged, when a lifting platform rises to a certain distance away from an opening of the wheel well, operation safety of maintenance personnel can be guaranteed through pulling and lifting of the pulling railing, falling is avoided, and meanwhile, a pullring arranged at the top of the railing provides convenience for the maintenance personnel to adjust the height of the railing.
Description
technical field [0001] The invention relates to a maintenance work ladder, in particular to a maintenance work ladder for wheel wells and landing gear of A330 series aircraft. Background technique [0002] Aircraft maintenance requires access to various parts of the aircraft, including landing gear and wheel wells. However, the landing gear and wheel wells are relatively high from the ground, and it is difficult for maintenance personnel to access without using a ladder. At this time, a suitable maintenance ladder is required. [0003] For the maintenance of the wheel wells and landing gear of A330 series aircraft, since the entrance of the wheel wells is higher than the ground, it is often necessary to figure 1 The maintenance work ladder is shown so that the maintenance engineer can efficiently access the wiring in the wheel well and the drive components of the landing gear. The wheel well entrance of the A330 series aircraft is relatively large, and there are many pipel...
