Description

Technical Field

[0001] The invention relates to the technical field of civil aviation maintenance tools, and in particular to a tool frame bracket for passenger aircraft maintenance. Background Art

[0002] HNA now has maintenance bases in Hainan, Northwest, Southwest, Fuzhou and other places. Maintenance personnel at each maintenance base need to carry a plastic tool box when repairing passenger aircraft. The tool box contains maintenance tools commonly used in the maintenance process. When repairing aircraft, it is often necessary to disassemble and assemble the cabin ceiling area. The cabin ceiling area is not too high, but ordinary people cannot reach it when standing. In addition, HNA's maintenance process standards do not allow stepping on the equipment on the aircraft to step on it. Therefore, sometimes maintenance personnel have to use existing tool boxes, stepladders, etc. to climb up. However, the structural strength of the existing plastic tool box does not allow it to serve as a low-height working platform, and the tool box will be very heavy if there are too many maintenance tools. It is time-consuming and laborious to carry and transport, which is very inconvenient. If you want to borrow a portable stepladder in the tool room to carry out maintenance work, there are the following problems: (1) The stepladder is inconvenient to carry; (2) The number of portable stepladders in the tool room is insufficient and it is difficult to meet the work needs; (3) The stepladder's working platform is small and inconvenient to use, which can easily cause personal injury and damage to tools. Furthermore, if the plastic tool boxes at all maintenance bases need to be replaced or upgraded in strength, operating costs will increase significantly. Summary of the invention
