Description

Technical Field

[0001] This utility model belongs to the field of drive device technology, specifically a drive device for a UAV detection radar turntable. Background Technology

[0002] The UAV detection radar turntable drive unit is a key component used to drive the radar turntable to rotate, enabling the radar to detect and track targets in different directions. The UAV detection radar turntable drive unit typically includes core structures such as servo motors, transmission mechanisms, and limit and locking components. For example, the servo motor drives the radar mounting base to rotate, and the turntable base, steering seat, and other mechanical structures achieve azimuth and pitch angle adjustments. Its limit unit may use a telescopic cylinder to push a push plate, and a pressure arm drives a fixed ring to make tight contact with a variable-diameter sleeve shaft, thereby locking the rotating shaft and ensuring the stability of the turntable at a specific angle. This type of device, by precisely controlling the radar's pointing angle, can achieve 360° all-around detection of targets in the airspace. The output shaft of the existing UAV detection radar turntable and drive unit is difficult to disassemble and assemble. When it is necessary to quickly move or change the detection scene, it will affect the mission response speed and also increase the risk of equipment damage due to the complexity of operation. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a UAV detection radar turntable drive device, which effectively solves the problem that the output shaft of the existing UAV detection radar turntable and drive device is difficult to disassemble and assemble, which affects the mission response speed when a rapid transfer or change of detection scene is required, and also increases the risk of equipment damage due to complex operation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a UAV detection radar turntable drive device, comprising a drive device body, four support legs fixedly installed at the bottom of the drive device body, a drive shaft fixedly installed at the upper part of the drive device body, a mating sleeve sleeved on the surface of the drive shaft, locking holes on both sides of the drive shaft, a rotating platform fixedly installed at the top of the mating sleeve, a receiver fixedly installed at the top of the rotating platform, and a handwheel provided on one side of the mating sleeve. The front and rear sides of the coupling sleeve are provided with slots, and the slots are provided with locking rods. The ends of the two locking rods that are far apart from each other are fixedly installed with pushing plates, and the ends of the two pushing plates that are far apart from each other are fixedly installed with contact heads. The surfaces of the two locking rods are covered with springs, and the two ends of the two springs are fixedly connected to the pushing plates and the interior of the slots, respectively. A transmission component is provided on one side of the handwheel. The transmission component is connected to the two contact heads. When the handwheel is rotated, the power is output to the two contact heads through the transmission component, so that the two contact heads drive the two locking rods into the interior of the two locking holes through the two pushing plates for limiting.

[0005] Preferably, sliding sleeves are fixedly installed on the upper and lower sides of the two pushing discs, and sliding rods are inserted inside the sliding sleeves. One end of each of the four sliding rods is fixedly connected to the inside of the two slots.

[0006] Preferably, the transmission assembly includes a rotating shaft, with bearings rotatably mounted on the surface of the rotating shaft. The upper part of each bearing is fixedly connected to the bottom of the rotating table via a fixing rod. A threaded rod is fixedly mounted on one end of the rotating shaft, and one end of the threaded rod is rotatably connected to one end of the mating sleeve. A threaded sleeve is threadedly connected to the surface of the threaded rod, and a support arm is fixedly mounted on the surface of the threaded sleeve. Push bars are fixedly mounted on both ends of one side of the support arm.

[0007] Preferably, both ends of the support arm are fixedly installed with limit sleeves, and limit rods are inserted inside the two limit sleeves. Both ends of the two limit rods are fixedly connected to the bottom of the rotating table through a hanger.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: During installation, the operator puts the docking sleeve at the bottom of the rotating table onto the surface of the drive shaft, and then the operator rotates the handwheel in the forward direction. When the handwheel rotates, it drives the rotating shaft to rotate inside the bearing. When the rotating shaft rotates, it drives the threaded sleeve to move through the threaded rod. When the threaded sleeve moves, it drives the two pushing bars to move through the support arm. When the pushing bars move, they all drive the limiting sleeve to slide along the surface of the limiting rod, which increases the stability of the two pushing bars when they move. When the two push bars move, they push the two contact heads towards each other. When the two contact heads move towards each other, the two push plates drive the two locking rods to move towards each other. As the push plates move, they both drive the sliding sleeves to slide along the surface of the sliding rods and simultaneously compress the springs, thereby increasing the stability of the two locking rods when they move. When the two locking rods move towards each other, they will lock into the inside of the two locking holes for limiting, thus quickly completing the installation. When disassembling, the operator rotates the handwheel in the opposite direction, causing the handwheel to drive the two push bars away from the two contact heads. After the pushing force of the two push bars is lost, the elastic force of the two springs will push the two locking rods to move in opposite directions, thus moving to the outside of the two locking holes to release the limiting, thereby quickly completing the disassembly. This allows the output shaft of the UAV detection radar turntable and drive device to be quickly assembled and disassembled. When it is necessary to transfer or change the detection scene, it can improve the mission response speed. The simple and quick operation also reduces the risk of equipment damage.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0012] Depend on Figures 1 to 5 As shown, this utility model includes a drive device body 1, four support legs 2 are fixedly installed at the bottom of the drive device body 1, a drive shaft 3 is fixedly installed at the top of the drive device body 1, a docking sleeve 5 is sleeved on the surface of the drive shaft 3, and a locking hole 4 is opened on both sides of the drive shaft 3. A rotating platform 6 is fixedly installed on the top of the docking sleeve 5, a receiver 25 is fixedly installed on the top of the rotating platform 6, and a handwheel 7 is provided on one side of the docking sleeve 5. Slots 8 are provided on both the front and rear sides of the docking sleeve 5. A locking rod 9 is inserted into the slot 8. A pushing plate 12 is fixedly installed at the far end of the two locking rods 9. A contact head 11 is fixedly installed at the far end of the two pushing plates 12. A spring 10 is sleeved on the surface of the two locking rods 9. The two ends of the two springs 10 are fixedly connected to the pushing plate 12 and the inside of the slot 8, respectively. A transmission component is provided on one side of the handwheel 7. The transmission component is connected to the two contact heads 11. When the handwheel 7 rotates, the power is output to the two contact heads 11 through the transmission component, so that the two contact heads 11 drive the two locking rods 9 into the inside of the two locking holes 4 through the two pushing plates 12 for limiting. Sliding sleeves 13 are fixedly installed on the upper and lower sides of the two pushing plates 12. Sliding rods 14 are inserted into the inside of each sliding sleeve 13. One end of each of the four sliding rods 14 is fixedly connected to the inside of the two slots 8.

[0013] During installation, the operator places the mating sleeve 5 at the bottom of the rotating table 6 onto the surface of the drive shaft 3. Then, the operator rotates the handwheel 7 in the forward direction. When the handwheel 7 rotates, it pushes the two contact heads 11 to move towards each other through the transmission component. When the two contact heads 11 move towards each other, they drive the two locking rods 9 to move towards each other through the two pushing discs 12. When the pushing discs 12 move, they drive the sliding sleeve 13 to slide along the surface of the sliding rod 14 and simultaneously compress the spring 10, thereby increasing the stability of the two locking rods 9 when they move. When the two locking rods 9 move towards each other, they will be locked into the inside of the two locking holes 4 for limiting, thereby quickly completing the installation. During disassembly, the operator rotates the handwheel 7 in the opposite direction, causing it to move away from the two contact heads 11 via the transmission assembly. This, in turn, pushes the two locking levers 9 to move in opposite directions under the elastic force of the two springs 10, thus moving them to the outside of the two locking holes 4 to release the limit and quickly complete the disassembly. This allows for quick assembly and disassembly of the UAV's detection radar turntable and the output shaft of the drive device. When it is necessary to transfer or change the detection scene, this improves the mission response speed, and the simple and quick operation also reduces the risk of equipment damage.

[0014] The transmission assembly includes a rotating shaft 15, on which bearings 16 are rotatably mounted. The upper part of each bearing 16 is fixedly connected to the bottom of the rotating platform 6 via a fixing rod 17. A threaded rod 18 is fixedly mounted at one end of the rotating shaft 15. One end of the threaded rod 18 is rotatably connected to one end of the mating sleeve 5. A threaded sleeve 19 is threadedly connected to the surface of the threaded rod 18. A support arm 20 is fixedly mounted on the surface of the threaded sleeve 19. Push bars 24 are fixedly mounted at both ends of one side of the support arm 20. Limit sleeves 21 are fixedly mounted at both ends of the support arm 20. Limit rods 23 are inserted inside the two limit sleeves 21. Both ends of the two limit rods 23 are fixedly connected to the bottom of the rotating platform 6 via a hanging rod 22.

[0015] During installation, the operator rotates the handwheel 7 clockwise. When the handwheel 7 rotates, it drives the shaft 15 to rotate inside the bearing 16. When the shaft 15 rotates, it drives the threaded sleeve 19 to move through the threaded rod 18. When the threaded sleeve 19 moves, it drives the two pushing bars 24 to move through the support arm 20. When the pushing bars 24 move, they both drive the limiting sleeve 21 to slide along the surface of the limiting rod 23, which increases the stability of the two pushing bars 24 when they move. When the two pushing bars 24 move, they push the two contact heads 11 to move towards each other.

[0016] During disassembly, the operator rotates the handwheel 7 in the opposite direction, causing the handwheel 7 to move the two push bars 24 away from the two contact heads 11. Thus, after losing the pushing force of the two push bars 24, the two contact heads 11 will be pushed to move in opposite directions by the elastic force of the two springs 10.
