Description

Technical Field

[0001] This utility model relates to the field of aviation ground support equipment technology, and in particular to a folding aircraft canopy seat hoisting device. Background Technology

[0002] Currently, the main body of aircraft canopies and seat cranes used for military aviation ground support is connected by welding, which means they cannot be disassembled. There is no room for structural optimization or improvement. Furthermore, the base and support legs are welded and cannot be folded or retracted, making it impossible to operate at different altitudes. They require a spacious operating environment and cannot rotate freely 360°, causing significant inconvenience for use and transport. In addition, existing aircraft canopy and seat cranes can only be operated by the operator based on intuition, which poses certain safety hazards and results in low lifting efficiency.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] See Figure 1 , Figure 2 A folding aircraft canopy seat hoisting device includes a chassis system, a rotating system, a telescopic system, and a hoisting system. The rotating system is mounted on the chassis system, the telescopic system is mounted on the rotating system, and the hoisting system is mounted on the telescopic system. The telescopic system includes a hydraulic unit and a multi-stage gear transmission unit. The hydraulic unit drives the hoisting system to move up and down, and the multi-stage gear transmission unit drives the hoisting system to telescopically move.

[0025] In this embodiment, the chassis system includes a chassis 1, on which four support components are provided. Each support component is equipped with transfer wheels 4 and support feet 3. The transfer wheels 4 are mounted on the chassis 1 via fixed brackets, and the support feet 3 are mounted on the fixed brackets and can rotate with the fixed brackets. The support feet 3 are equipped with a lifting mechanism. When the hoisting device is working, the support feet 3 support the entire device. When the hoisting device needs to be moved, the support feet 3 are retracted, and the hoisting device is moved by the transfer wheels 4.

[0026] In this embodiment, the chassis 1 is also equipped with a traction rod 5 and a rotating handwheel 2. The hoisting device can be moved manually or by a tractor through the traction rod 5. In addition, the rotating handwheel 2 is connected to the rotating system, and the rotating system can be driven to rotate by rotating the handwheel 2.

[0027] In this embodiment, the rotating system includes a horizontal rotating platform 6, which is mounted on a chassis 1 and has a support frame 7 connected to the telescopic system. The horizontal rotating platform 6 also includes a lifting winch 24 and a hanging ring 23. The lifting winch 24 is equipped with a wire rope 21, which is mounted on the telescopic system and the hoisting system and connected to the hook 22 of the hoisting system. The hanging ring 23 is used to secure the hook 22 when the hoisting device is moved.

[0028] In this embodiment, the telescopic system includes three boom sections 10. One end of each boom section 10 is connected to the support frame 7, and the other end is connected to the hoisting system. The boom sections 10 are also connected to the horizontal rotating platform 6 via a hydraulic unit.

[0029] In this embodiment, the hydraulic unit includes a hydraulic mechanism 8 and a support shaft 9. One end of the hydraulic mechanism 8 is mounted on the horizontal rotating platform 6, and the other end is connected to the three-section boom 10. One end of the support shaft 9 is mounted on the horizontal rotating platform 6, and the other end is connected to the three-section boom 10. The hydraulic mechanism 8 and the support shaft 9 enable horizontal and oblique displacement of the three-section boom 10. After reaching the predetermined position, the support shaft 9 locks its length, the hydraulic mechanism 8 releases pressure, and the support shaft 9 acts as a load-bearing component.

[0030] In this embodiment, the multi-stage gear transmission unit includes a first handwheel 12 and a second handwheel 15. The first handwheel 12 is equipped with a first locking pin 13 and a first gear and rack mechanism 14; the second handwheel 15 is equipped with a second locking pin 16 and a second gear and rack mechanism 17. The first gear and rack mechanism 14 and the second gear and rack mechanism 17 drive the three-section boom 10 to perform telescopic movement. When the hoisting device is working, the locking pins (including the first locking pin 16 and the second locking pin 16) are pulled out, and the handwheels (including the first handwheel 12 and the second handwheel 15) are manually rotated. The gears drive the racks (including the first gear and rack mechanism 14 and the second gear and rack mechanism 17) to achieve telescopic movement of the three-section boom 10. After telescopic movement to the designated position, the locking pins (including the first locking pin 16 and the second locking pin 16) are inserted.

[0031] In this embodiment, the three-section boom 10 is equipped with boom detection sensors 11. The boom detection sensors 11 include one or more of attitude sensors and load sensors. The attitude sensors and load sensors can monitor the tilt angle and load distribution of the boom in real time. In conjunction with a controller, such as a PLC, the boom detection sensors 11 upload the collected boom information to the PLC. The output terminal of the PLC is connected to the hydraulic mechanism 8. The PLC can automatically adjust the start and stop of the hydraulic mechanism 8, further improving the safety and work efficiency of operating the lifting device.

[0032] In this embodiment, the hoisting system includes a horizontal boom mechanism 20 and a hook 22. The horizontal boom mechanism 20 is connected to the three-section boom 10 via a hinge mechanism 18. An inclined support beam 19 is also provided between the horizontal boom mechanism 20 and the three-section boom 10. When the hoisting device is working, the horizontal boom mechanism 20 rotates to a predetermined position via the hinge mechanism 18 and unfolds the inclined support beam 19. The inclined support beam 19 connects and fixes the horizontal boom mechanism 20 and the three-section boom 10. It should be noted that a support attachment point is provided on the three-section boom 10 to support the inclined support beam 19. This support attachment point is used to support the horizontal boom mechanism 20 when the hoisting device is working (see [reference]). Figure 1 Furthermore, a tightening attachment point is provided on the support shaft 9 for tightening the inclined support beam 19. This tightening attachment point is used to fix the inclined support beam 19 when the hoisting device is transferred (see [reference]). Figure 2 The hook 22 is connected to the lifting winch 24 via a wire rope 21. The wire rope 21 is mounted on the three-section boom 10 and the horizontal boom mechanism 20. Safety protection devices, such as tensioners and weight limiters, can also be installed on the three-section boom 10 or the horizontal boom mechanism 20.
