Aircraft maintaining dock

Abstract

The invention discloses an aircraft maintaining dock and belongs to the technical field of aircraft maintaining docks. A walking mechanism is electrically driven and is designed without tracks, pull-push plates are in gear and rack transmission, and a safety rope of a safety protective device is used for being tied and hung on a slide track car. The aircraft maintaining dock comprises a dock main body, the electric walking mechanism, maintaining workbenches, the pull-push plates, pull-push plate manual mechanisms and a safety protective mechanism. The electric walking mechanism is placed at the lower end of the dock main body. A plurality of maintaining workbenches are arranged in the dock main body. The pull-push plates and the pull-push plate manual mechanisms are arranged in the maintaining workbenches. The safety protective mechanism is arranged on a structure beam of the dock main body at the lower end of the maintaining workbenches. The electric walking mechanism comprises a transmission part and a control part. Each pull-push plate manual mechanism comprises a fixing seat, a slide groove, a rack, a gear, a gear shaft, a locking disc, a spring and a spring mounting cylinder. The rack is fixedly arranged on each pull-push plate. The safety protective mechanism comprises a slide track, a limiting block, the track car and a tying-hanging ring.

Description

technical field [0001] The invention belongs to the technical field of aircraft maintenance docks, and in particular relates to an aircraft maintenance in which the traveling mechanism adopts electric drive and has a trackless design, the pull plate adopts gear and rack transmission, and the safety protection device adopts a safety rope to hang on a rail car. dock. Background technique [0002] An aircraft maintenance dock is actually a platform used for aircraft maintenance. Due to the huge size of the aircraft, people's heights are very different from the size of the aircraft under normal circumstances, and they cannot touch all the parts that need to be repaired on the aircraft. In this case, people have designed various platforms to meet the maintenance work of the aircraft. But also because of this reason, it is determined that the overall size of the aircraft maintenance dock will inevitably become very large. [0003] At this stage, there are two main types of aircr...

Problems solved by technology

Due to the aircraft, the size of the maintenance dock has also become larger, and the height from the ground is very high, so the manual towing method is extremely dangerous

[0007] The second is chain drive dragging. This method has a great improvement over the first method and solves the safety problem. However, after a long-term use of the chain, there will be chain wear and pitch elongation, which will lead to its reliability. In addition, in order to realize the telescopic action of the pull plate, the space occupied by the chain dragging mechanism is also very large, which is not conducive to the optimization of the structure of the aircraft maintenance dock

In this way, maintenance personnel need to take off or hang up the safety rope from time to time, which is not conducive to continuous operations such as painting, and it is also difficult to ensure work efficiency. At the same time, it is limited by the structure of the aircraft maintenance dock itself, and some areas cannot be tied for safety. ropes, making it difficult for maintenance personnel to effectively guarantee the safety of their lives when working in these areas
