Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a lifting device for an unmanned aerial vehicle (UAV) hangar platform. Background Technology

[0002] Unmanned aerial vehicles (UAVs) can be used for aerial photography, resource surveys, patrols, and delivery of disaster relief supplies. With the popularization of aircraft attitude control systems and aerospace technology, UAVs of various sizes are gradually entering the civilian market. The UAV hangar platform lifting device is a vertical scheduling device that can move the UAV carrier plate up and down inside the hangar.

[0003] For example, Chinese Patent Application No. 202220206833.3 discloses a lifting device for a drone hangar platform, belonging to the field of drone hangar technology. It includes a receiving platform for receiving landing drones, and a lifting mechanism for controlling the vertical movement of the receiving platform. The lifting mechanism includes a base and a fixed platform support. The upper end of the fixed platform support is connected to the receiving platform, and a lifting support sleeve is fixed to the lower end of the fixed platform support. A lead screw and a transmission assembly for rotating the lead screw are rotatably arranged on the upper side of the base. A lifting block is slidably arranged inside the lifting support sleeve. A threaded hole is opened in the middle of the lifting block, and the lead screw is threadedly connected to the lifting block through the threaded hole. An elastic buffer assembly is arranged between the lifting block and the lifting support sleeve, and the lifting block drives the lifting support sleeve to move vertically through the elastic buffer assembly. This device provides shock absorption and cushioning for the drone when it lands on the receiving platform or during movement and transportation.

[0004] However, the lifting device described above uses a lead screw to control the lifting process, which results in low lifting efficiency and cannot meet the efficiency requirements for rapid dispatch of drones. Therefore, those skilled in the art have provided a drone hangar platform lifting device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a lifting device for an unmanned aerial vehicle (UAV) hangar platform to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0014] By adopting the above technical solution, the brake can achieve self-locking of the rotating shaft, preventing the receiving platform from sliding down on its own due to load.

[0015] As a further description of the above technical solution:

[0016] A through groove is provided on one side of the connecting housing, and the size of the through groove is adapted to the size of the metal gear.

[0026] This utility model has the following beneficial effects:

[0027] 1. Compared with existing technologies, this drone hangar platform lifting device, by setting up a lifting mechanism, controls the lifting of the receiving platform. After the lifting rack rises and falls, it drives the receiving platform fixed to it to move vertically. Even in the power failure state, the self-locking of the rotating shaft by the brake can effectively maintain the stationary position of the receiving platform and prevent it from sliding down due to load. It is safe and reliable, and can achieve both stable low-speed operation and high lifting speed, which can meet the efficiency requirements of rapid drone dispatch.

[0028] 2. Compared with the existing technology, the lifting device of this drone hangar platform is equipped with a stabilizing mechanism.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-4 In this embodiment of the utility model, a lifting device for an unmanned aerial vehicle hangar platform includes a mounting base 1, a metal bracket 2 fixed to the top of the mounting base 1, a lifting mechanism 3 fixed to one side of the metal bracket 2, a receiving platform 4 connected to the top of the lifting mechanism 3, a placement groove 5 opened on the top of the receiving platform 4, and a stabilizing mechanism 6 installed on the top of the mounting base 1.

[0036] The lifting mechanism 3 includes a support base 31, a connecting housing 32 fixed to the top of the support base 31, a lifting rack 33 extending outwards movably inserted into the connecting housing 32, a metal seat 34 fixed to the top of the mounting base 1, a metal pad 35 mounted on the top of the metal seat 34, a servo motor 36 fixed to the top of the metal pad 35, a rotating shaft 38 fixed to one end of the output shaft of the servo motor 36, a brake 37 fixed to the top of the mounting base 1, a metal gear 39 fixed to the outside of the rotating shaft 38, the metal gear 39 meshing with the lifting rack 33, and the lifting rack 33 being fixedly connected to the receiving platform 4. When the rotating shaft 38 drives the metal gear 39 to rotate, it can drive the lifting rack 33 and the receiving platform 4 to move vertically. The brake 37 has a mounting hole inside, the size of which is adapted to the size of the rotating shaft 38. The brake 37 can complete the self-locking of the rotating shaft 38 to prevent the receiving platform 4 from sliding down due to the load. A through groove is opened on one side of the connecting housing 32. The size of the through groove is adapted to the size of the metal gear 39 to ensure that the metal gear 39 rotates normally. The support base 31 and the mounting base 1 are fixedly connected, and the servo motor 36 and the metal pad 35 are fixed together by bolts.

[0037] The stabilizing mechanism 6 includes a fixed frame 61, a fixed plate 62 fixed on one side of the fixed frame 61, a lifting threaded column 63 movably inserted into the top of the fixed plate 62 and passing through its bottom, a support sleeve 64 fixed to the top of the lifting threaded column 63, a handle pad 65 connected to the bottom of the fixed plate 62, and two limit nuts 66 threadedly connected to the outer side of the lifting threaded column 63. The fixed frame 61 and the mounting base 1 are fixedly connected, and the inner wall of the support sleeve 64 fits against the rotating shaft 38.

[0038] The working principle of this utility model is as follows: When controlling the lifting and lowering of the receiving platform 4, the servo motor 36 on the top of the metal pad 35 can be activated. The output shaft of the servo motor 36 drives the rotating shaft 38 to rotate. After the rotating shaft 38 drives the metal gear 39 to rotate, the metal gear 39 drives the lifting rack 33 meshing with it to move vertically. The connecting housing 32 plays a role in limiting the lifting rack 33. After the lifting rack 33 rises and falls, it drives the receiving platform 4 fixed to it to move vertically. Even in the power failure state, the brake 37 achieves self-locking of the rotating shaft 38, which can effectively maintain the stationary position of the receiving platform 4 and prevent it from sliding down due to load. It is safe and reliable, and can achieve both smooth low-speed operation and high speed operation. The high lifting speed can meet the efficiency requirements of rapid drone dispatch. With the stabilizing mechanism 6, when the rotating shaft 38 is locked for a long time, the user can rotate the two limit nuts 66 on the outside of the lifting threaded column 63 to make the corresponding surface of the limit nuts 66 move away from the fixed plate 62. Then, push the handle pad 65 vertically to make the handle pad 65 move the lifting threaded column 63. After the support sleeve 64 at the top of the lifting threaded column 63 is in contact with the rotating shaft 38, rotate the two limit nuts 66 on the outside of the lifting threaded column 63 to make the corresponding surface of the limit nuts 66 press tightly against the fixed plate 62. This can lock the position of the support sleeve 64 and provide auxiliary support for the rotating shaft 38 to ensure the structural stability after the rotating shaft 38 is locked.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
