Please refer to FIG. 1 . FIG. 1 is a schematic structural diagram of the lifting platform 100 . This embodiment provides an elevator platform 100 for aircraft maintenance, which has the function of enabling maintenance personnel to move in multiple directions, so as to facilitate maintenance of areas that are difficult to access to the aircraft. When maintenance personnel repair the aircraft through the traditional maintenance platform, there are many areas on the aircraft that cannot be approached and thus cannot be maintained, which has a great impact on the maintenance work of the aircraft. The lifting platform 100 provided in this embodiment can well solve the above problems.

The lifting platform 100 mainly includes a supporting unit 110 , a moving unit 120 , a lifting unit 130 , a rotating unit 140 and an adjusting unit 150 . The moving unit 120 , the lifting unit 130 , the rotating unit 140 , and the adjusting unit 150 are all connected to the supporting unit 110 . The moving unit 120 can drive the lift platform 100 to move as a whole, so that maintenance personnel can perform maintenance on most areas of the aircraft through the lift platform 100 . The lifting unit 130 is used to adjust the height of the maintenance personnel. The rotation unit 140 can be rotated in the horizontal plane, thereby adjusting the angle between the maintenance personnel and the aircraft. The adjustment unit 150 can be extended and retracted in the horizontal plane, so as to adjust the distance between the maintenance personnel and the aircraft.

The supporting unit 110 mainly includes a base 112 , a first supporting member 114 , a second supporting member 116 and a third supporting member 118 . The base 112 provides a mounting base for the lift platform 100 . The moving unit 120 is mounted on the base 112 , and moves the lift platform 100 as a whole by moving the base 112 . The base 112 is connected to the first support member 114 through the lift unit 130 , and the height of the first support member 114 is adjusted by the lift unit 130 . The first support member 114 and the second support member 116 are connected by a rotating unit 140 , and the angle between the second support member 116 and the aircraft is adjusted by the rotating unit 140 . The third support 118 provides an operating platform for maintenance personnel. The third supporting member 118 is connected to the second supporting member 116 through the adjusting unit 150 , and the adjusting unit 150 is extended and retracted with the second supporting member 116 as a base, so the third supporting member 118 can be connected with the second supporting member 118 under the action of the adjusting unit 150 . The relative displacement of the member 116 occurs, thereby adjusting the distance between the third support member 118 and the aircraft.

At the same time, since the relative heights of the third support member 118 , the second support member 116 and the first support member 114 remain unchanged, when the lifting unit 130 is lifted and lowered, the second support member 116 and the third support member 118 will also follow the A support member 114 is lifted and lowered simultaneously. In addition, since there is no relative rotation between the third support member 118 and the second support member 116 , when the rotating unit 140 rotates, the third support member 118 rotates synchronously with the second support member 116 .

Further, a plurality of guardrails 119 are also provided on the edge of the third support member 118 . The guardrail 119 can play a protective role for the maintenance personnel, reduce the possibility of the maintenance personnel falling from the air when maintaining the aircraft on the third support 118, increase the operational safety factor of the maintenance personnel, and improve the life safety of the maintenance personnel. guarantee.

Please refer to FIGS. 2 and 3 . FIG. 2 is a schematic structural diagram of the third supporting member 118 when the guardrail 119 is erected, and FIG. 3 is a schematic structural diagram of the third supporting member 118 when the guardrail 119 is retracted. In this embodiment, the plurality of guardrails 119 are all rotatably connected to the third support member 118 , and the rotation directions of the plurality of guardrails 119 are all toward the inner side of the third support member 118 (as shown in FIG. 3 ). When the guardrail 119 affects the work of the maintenance personnel, the maintenance personnel can turn the guardrail 119 down (as shown in FIG. 3 ), so as to facilitate the subsequent work. After the maintenance is completed, the guardrail 119 is rotated to the original position (as shown in FIG. 2 ). Due to the setting of the rotation direction of the guardrail 119, the guardrail 119 will not rotate to the outside of the third support member 118. Therefore, when the third support member 118 moves, the rotated and lowered guardrail 119 will not collide with the aircraft, and will not cause damage to the aircraft and maintenance. work affects.

Of course, in other embodiments, the plurality of guardrails 119 may also be detachably connected to the third support member 118 . When the maintenance personnel are maintaining the aircraft on the third support 118, when the guardrail 119 affects the maintenance work, the maintenance personnel can disassemble the guardrail 119 and place it on the third support 118. After the maintenance is completed, the guardrail 119 can be removed. The guardrail 119 is installed back in place. However, there is a problem in this. During the work process of the maintenance personnel, the guardrail 119 may be accidentally kicked off from the third support 118, which may cause damage to the aircraft or even the personnel below, and has a great potential safety hazard.

Please refer to Figure 1 again. In this embodiment, the moving unit 120 mainly includes a plurality of scroll wheels 122 . The plurality of scroll wheels 122 are mounted on the base 112 . Further, the rolling wheel 122 can be a universal wheel with brake pads. The setting of the universal wheel makes the movement of the lifting platform 100 more flexible and the steering more convenient. At the same time, the existence of the brake pads also enables the lifting platform 100 to stop moving in time, and the positioning is more accurate. Moreover, the setting of the brake pads can also make the lifting platform 100 stay in place without moving after it stops moving, so that the fixing of the lifting platform 100 is more reliable, and a relatively stable operation platform is provided for the maintenance personnel on the third support 118. Enhance the work safety factor of maintenance personnel and ensure the work accuracy of maintenance personnel.

Please refer to FIG. 1 and FIG. 4 . FIG. 4 is a schematic structural diagram of the lifting unit 130 when it is lifted.

The lifting and lowering of the diamond-shaped telescopic frame 132 is controlled and adjusted through the telescopic expansion of the first telescopic cylinder 134 . After the diamond-shaped telescopic frame 132 is lifted and lowered, the angle between the diamond-shaped telescopic frame 132 and the telescopic end of the first telescopic cylinder 134 will change. That is, it can be ensured that the telescopic end of the first telescopic cylinder 134 can always be connected to the diamond-shaped telescopic frame 132 .

Please refer to Figure 1 again. In this embodiment, the rotating unit 140 includes a rotating shaft 142 and a driving motor 144 . One end of the rotating shaft 142 is fixed to the first support member 114 through a bearing (not shown in the figure), and the other end is fixedly connected to the second support member 116 . Therefore, the second supporting member 116 can rotate relative to the first supporting member 114 under the driving of the rotating shaft 142, thereby adjusting the angle between the second supporting member 116 and the aircraft. The driving motor 144 is mounted on the first support member 114 . A gear 143 is provided on the rotating shaft 142 , and the gear 143 is located between the first support member 114 and the second support member 116 . The driving motor 144 is connected to the rotating shaft 142 in a transmission through the gear 143 . The rotation of the rotating shaft 142 is controlled by the transmission of the drive motor 144 and the gear 143, thereby controlling the angle between the maintenance personnel and the aircraft. Of course, in other embodiments, the rotating unit 140 may also adopt other settings, for example, the second support 116 is screwed to the first support 114, etc., as long as the second support 116 can rotate relative to the first support 114. function.
