Detailed Description
Example 1. A helicopter ground transition tool is shown in figures 1-7 and comprises a main lifting tool for fixing a front landing gear joint of a helicopter and a tail lifting tool for fixing a rear landing gear joint of the helicopter; the main lifting tool comprises a long base 1, support frames 2 are arranged at positions, close to two ends, of the long base 1, the tops of the support frames 2 are connected with pressing blocks 3, and circular groove structures 4 used for fixing joints of the front landing gear of the helicopter are dug between the tops of the support frames 2 and the pressing blocks 3; the tail lifting tool comprises a base assembly, wherein an upright post 6 is arranged on the base assembly, and a fixing frame 7 used for fixing a joint of a rear landing gear of the helicopter is arranged on the upper portion of the upright post 6.
The inner wall of the circular groove structure 4 is covered with a rubber pad 5. The rubber pad 5 is used for preventing the tooling from scratching the fixed position of the helicopter.
The two support frames 2 are symmetrical about the central axis of the long base 1. The structure can ensure the reliable fixation of the position of the front landing gear of the helicopter.
A connecting seat 8 is arranged on the column body of the upright column 6, the connecting seat 8 is connected with one end of a connecting rod 9, and the other end of the connecting rod 9 is connected with the helicopter body; the connecting rod 9, the upright post 6 and the fixing frame 7 form a triangular supporting structure for the helicopter body. The triangular support structure can increase the stability of fixation.
The height of the connecting seat 8 can be adjusted along the column body of the upright post 6; the length of the connecting rod 9 is adjustable. This structure can adjust the equipment according to actual conditions, and the adaptability is stronger.
The base assembly comprises a base plate 10, wherein the base plate 10 is connected with a damping spring 11 and a damping plate 12; the shock absorption plate 12 is provided with a vertical column 6.
The helicopter fixing operation steps are as follows:
placing the helicopter rotating tool on the flat trailer 13 by using a forklift, and preliminarily determining the position;
hoisting the helicopter by using a complete machine hanger and a truss hanger, and slowly moving the helicopter to the position above the trailer transferring tool;
the truss crane is controlled to slowly move downwards to the connecting point of the tail lifting tool, and a rear landing gear joint of the helicopter and a fixed frame 7 of the tail lifting tool are connected and fixed through a mounting bolt; preferably, the upright post 6 is connected with the helicopter body by the connecting rod 9 to form a triangular supporting structure, so that the position of the rear landing gear of the helicopter is more reliably fixed;
