Embodiment Construction

[0020] Such as Figure 1-Figure 5 As shown, the drop-mounted engine installation vehicle is composed of a traveling mechanism, a lifting mechanism, a traversing mechanism, a rolling mechanism, a propulsion mechanism, a fine-tuning mechanism and a hydraulic system.

[0021] The lifting mechanism is installed at the upper end of the traveling mechanism, and the connecting beam 12 fixes the lifting mechanism, the traversing mechanism and the rolling mechanism together, and a propulsion mechanism and a fine-tuning mechanism are installed at the upper end of the traversing mechanism.

[0022] Such as figure 2 As shown, the walking mechanism is: the chassis 1 is provided with wheels 2 and load-bearing feet 3, and a group of steering traction devices are respectively installed at both ends of the chassis 1. The steering traction device is that the two ends of the tie rod 4 The end is fixed with the chassis 1 through the steering knuckle 5, the middle part of the tie rod 4 is connec...

Abstract

The invention relates to a fall-mounted type engine installing vehicle. According to the adopted technical scheme, the fall-mounted type engine installing vehicle is composed of a walking mechanism, a lifting mechanism, a transverse moving mechanism, a transverse rolling mechanism, a pushing mechanism, a fine adjustment mechanism and a hydraulic system. The lifting mechanism is arranged at the upper end of the walking mechanism, and the lifting mechanism, the transverse moving mechanism and the transverse rolling mechanism are fixed together through connecting beams. The pushing mechanism and the fine adjustment mechanism are arranged at the upper end of the transverse rolling mechanism. The fall-mounted type engine installing vehicle has the basic requirements for easy operation, high safety and reliability, reasonable design and layouts, convenient maintenance and the like and meets the requirements for reliability, maintainability, testability, supportability, safety and environment practicability. By means of the fall-mounted type engine installing vehicle, the posture adjustment of six freedom degrees including longitudinal movement, lifting, transverse movement, pitching, transverse rolling and deflecting of an engine can be efficiently, accurately and safely achieved.

Description

technical field [0001] The invention relates to the installation of aircraft engines, is particularly suitable for the installation of drop-mounted engines from top to bottom, and belongs to the field of aviation manufacturing engineering / aircraft assembly. Background technique [0002] With the continuous development of aircraft engines, the installation methods of aircraft body and engines are also constantly updated. The original engine installation vehicle is difficult to adapt to the requirements of the new situation, and cannot meet the docking work between the engine and the airframe. Through the detailed analysis of the installation forms of aircraft engines currently in service and under development in China, the existing installation forms of aircraft engines mainly include a series of engine installation vehicles such as drop-mounted, propulsion, small mechanical and small electric vehicles. Therefore, how to integrate various forms together to achieve generaliza...
