Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Such as Figures 1-3As shown in the figure, an aircraft converter disassembly and assembly lifting trailer includes a tray rack 1 and a plurality of locking universal wheels 2 installed at the bottom thereof, and further includes: an installation lifting mechanism for lifting and installing the converter components to be installed. The installation lifting mechanism is located above the tray rack 1. The installation lifting mechanism includes a scissor lift 3 and a top plate 4. The bottom and top of the scissor lift 3 are respectively connected with an installation plate 5 and a lift plate 501. Both sides of the top of the lift plate 501 are fixedly connected with fixing plates 502. The outer wall of the fixing plate 502 is fixedly connected with a servo motor 504. The output end of the servo motor 504 is fixedly connected with a rotating shaft 503, and the rotating shaft 503 rotates and extends between the two fixing plates 502. The outer side walls of the rotating shaft 503 and the bottom of the installation plate 5 are both fixedly connected with plug-in plates 505. One side of the plug-in plate 505 is provided with a limit chute, and a jack is opened inside the limit chute. An installation magnet 5010 is fixedly connected inside the jack. One side of the top of the tray rack 1 and one side of the top plate 4 are both slidably connected with sliding plug rods 506. One end of the sliding plug rod 506 is fixedly connected with a protective shell 508. Both sides of the outer wall of the sliding plug rod 506 are fixedly connected with tension springs 507. One end of the sliding plug rod 506 away from the protective shell 508 is fixedly connected with a sliding magnet 509;

[0027] The present invention is further specifically described in detail. Plug-in slots are opened at the top of the tray rack 1 and the bottom of the top plate 4. The plug-in plate 505 is slidably arranged with the plug-in slot. One end of the sliding plug rod 506 where the sliding magnet 509 is located slides and extends into the plug-in slot. One end of the tension spring 507 away from the sliding plug rod 506 is connected to the outer walls of the tray rack 1 and the top plate 4, and both the tension spring 507 and the sliding plug rod 506 are located inside the protective shell 508. The sliding magnet 509 and the installation magnet 5010 are arranged to attract each other with opposite poles. The sliding plug rod 506 and the jack are correspondingly slidably arranged. The outer side wall of the sliding plug rod 506 is slidably fitted with the inner side wall of the limit chute;

[0028] As can be seen from the above, by the action of the scissor lift 3, the converter components can be placed above the top plate 4 and lifted, so that the relatively large-sized converter can be correspondingly installed with the aircraft, and correspondingly, it is convenient for the staff to move and adjust the angle of the components, thereby improving the work efficiency of the staff in disassembling and assembling the converter;

[0029] When the scissor lift 3 is damaged and needs to be disassembled and replaced, the protective shell 508 is pulled to drive the sliding plug rod 506 to disengage from the socket on the plug board 505, release the fixing effect between the plug board 505 and the tray frame 1 and the top plate 4, and then the scissor lift 3 can be removed. When installing it, the plug board 505 is inserted into the inside of the plug slot, and the limiting slide groove on one side of it slides correspondingly with the sliding plug rod 506. When the sliding plug rod 506 corresponds to the socket, according to the sliding The moving magnetic block 509 and the installation magnetic block 5010 have the effect of attracting each other with opposite poles, so that the sliding plug rod 506 can be inserted into the socket, and the plug-in board 505 can be plugged and fixed, so that the scissor lift 3 can be installed and used. Through the setting of this structure, according to the corresponding plug-in effect of the sliding plug rod 506 and the socket, the installation method of the scissor lift 3 is simplified, and it is convenient for the staff to disassemble and install the scissor lift 3, thereby improving the work efficiency of the staff to disassemble and install the converter components using the scissor lift 3;

[0030] It should be noted that one side of the protective shell 508 does not fit with one side of the tray frame 1 and the top plate 4 in the initial state, and only fits with the outer wall of the tray frame 1 and the top plate 4 when the sliding rod 506 is inserted into the insertion hole;

[0031] Through the cooperation between the servo motor 504 and the rotating shaft 503, by rotating the servo motor 504 forward or reversely, the rotating shaft 503 can drive the plug-in board 505 to rotate and tilt, and the top plate 4 can adjust the tilt angle, thereby improving the use effect of this device.

[0032] Furthermore, the present design application is applied to the field of disassembly and assembly of aviation inverters.
