[0029] Refer to Figures 1 to 3An aircraft alternator installation auxiliary device shown in the figure includes a mobile base 10, a lifting platform 20, a rotating seat 30, and a placement bracket 40; the lifting platform 20 is installed on the mobile base 10; the rotating seat 30 is rotatably installed on the lifting end of the lifting platform 20; the placement bracket 40 is hinged to the rotating seat 30, and the placement bracket 40 can be self-locked relative to the rotating seat 30.

[0030] Among them, the lifting platform 20 can be a conventional cylinder lifting platform, a rack and pinion lifting platform, or a shear frame platform, etc. In order to facilitate the movement and fixation of the mobile base 10, several brake wheels 11 are provided at the bottom of the mobile base 10. In addition, an installation position for limiting and fixing the alternator is provided on the placement bracket 40, which is convenient for lifting the alternator.

[0031] See Figure 1 and Figure 2 For the convenience of lifting and improving the stability of lifting, the lifting platform 20 includes a pair of shear frames, a platform plate 22, and an adjusting screw 23. The hinge centers of the pair of shear frames are connected by a connecting shaft 24 and arranged in parallel; the same ends of any two parallel support arms 25 of the two shear frames are hinged to the mobile base 10, and the other ends are slidably installed on the back surface of the platform plate 22. The two ends of the remaining two parallel support arms 25 of the two shear frames are respectively slidably installed on the back surface of the platform plate 22 and the mobile base 10.
