Description

Technical Field

[0001] This utility model relates to the field of aircraft radar technology, and more specifically, to an aircraft radar dome lifting device that is easy to assemble and disassemble. Background Technology

[0002] Aircraft radar is an electronic device that uses radio waves to detect and locate targets. It can be used for navigation and positioning, helping aircraft to accurately determine their position and course. In terms of weather detection, pilots can obtain real-time weather information ahead and avoid severe weather through weather radar. It also has military applications, capable of detecting and tracking enemy targets and providing pilots with battlefield information.

[0003] An aircraft radome is a hemispherical fiberglass dome on the nose of an aircraft. It serves as a protective shell for the radar system. The radome is designed to protect the internal radar antenna from harsh external environments such as high-speed airflow, rain, and hail, while ensuring that electromagnetic radiation can pass through freely without affecting the radar's detection performance.

[0004] Current aircraft radome lifting equipment, such as Chinese patent CN202322109904.5 "An aircraft radome lifting device that is easy to install and disassemble," uses a screw-mounted fixing component and several lateral positioning screw holes to adjust the horizontal position and number of the fixing component, achieving stable fixing of radomes of different specifications. Then, it is lifted by a lifting mechanism to achieve stable fixing of aircraft radomes of different sizes and specifications, and also facilitates the maintenance of the suction cup. However, in practical applications, the aircraft radome is fixed on the top of the positioning plate. When the radome is docked with the aircraft nose, the position of the fixing base plate needs to be frequently adjusted, making the installation and disassembly of the radome difficult. Furthermore, since the radome is usually streamlined, the fixing component needs to be replaced according to the radome model when supporting the radome, which is time-consuming and labor-intensive. Therefore, it needs to be improved and optimized. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an aircraft radome lifting device that is easy to install and disassemble, which has the advantage of facilitating the installation and removal of the radome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aircraft radome lifting device that is easy to assemble and disassemble, comprising a lifting platform and an aircraft radome, wherein each of the four corners of the bottom of the lifting platform is rotatably mounted with a movable wheel, and a fixed base is fixedly mounted on the top of the lifting platform. The top of the fixed base has first guide grooves on both the front and rear sides. A first lead screw is rotatably installed inside the first guide groove on the front side, and a guide rod is fixedly installed inside the first guide groove on the rear side. Slider blocks are movably installed inside both sets of first guide grooves. A moving platform is fixedly installed on the top of the two sets of sliders. A motor is fixedly installed on the right side of the fixed base. The output shaft of the motor is fixedly connected to the first lead screw.

[0018] 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.

[0019] like Figures 1 to 6 As shown, this utility model provides an aircraft radome lifting device that is easy to assemble and disassemble, including a lifting platform 1 and an aircraft radome 3. The four corners of the bottom of the lifting platform 1 are rotatably mounted with moving wheels 2, and the top of the lifting platform 1 is fixedly mounted with a fixed seat 4. The top of the fixed base 4 has first guide grooves 5 on both the front and rear sides. A first lead screw 7 is rotatably installed inside the front first guide groove 5, and a guide rod 6 is fixedly installed inside the rear first guide groove 5. Slider 10 is movably installed inside both sets of first guide grooves 5. A moving stage 9 is fixedly installed on the top of the two sets of slider 10. A motor 8 is fixedly installed on the right side of the fixed base 4. The output shaft of the motor 8 is fixedly connected to the first lead screw 7. The front slider 10 and the first lead screw 7 are threaded together, and the rear slider 10 and the guide rod 6 are sleeved together. The front and rear sides of the top of the mobile platform 9 are provided with horizontal grooves 12. A clamping block 17 is movably installed inside the horizontal groove 12. A first suction cup 18 is fixedly installed on the top of the clamping block 17, and the clamping block 17 and the first suction cup 18 fix the aircraft radar dome 3.

[0020] When installing the aircraft radome 3, the operator first rotates the rotating disk 21 according to the length of the radome 3. The rotation of the rotating disk 21 drives the second lead screw 20 to rotate. The second lead screw 20 then drives the positioning pin 22, which is threaded onto it, to move along the second guide groove 19. After moving to the appropriate position, the operator lifts the aircraft radome 3 to the top of the moving platform 9 and aligns the right end of the aircraft radome 3 with the second suction cup 23 to complete the positioning of the right end of the aircraft radome 3. Then, the operator activates the three sets of cylinders 11 in sequence. The operation of the cylinders 11 drives the moving block 13 to move towards the center of the positioning chamber 14. Furthermore, the rack 15 at one end of the moving block 13 drives the gear 16 meshing with it to rotate. At this time, the two sets of moving blocks 13 move towards the center of the positioning chamber 14 synchronously, and the distance between the two sets of clamping blocks 17 shortens, making... The first suction cup 18 supports and fixes the outer wall of the aircraft radome 3. After fixing, the front and rear clamping blocks 17 move synchronously, so that the aircraft radome 3 is located in the center of the moving platform 9, which facilitates the subsequent docking of the aircraft radome 3 with the aircraft. Then, the staff moves the lifting platform 1 to a suitable position and starts the lifting platform 1, so that the aircraft radome 3 is lifted to the nose position of the aircraft. Then the motor 8 is started. The operation of the motor 8 drives the first lead screw 7 to rotate. The first lead screw 7 further drives the slider 10, which is threaded with it, to move to the left, so that the moving platform 9 moves to the left side of the fixed seat 4. Further, the aircraft radome 3 is moved to the nose position of the aircraft, which facilitates the installation and removal of the aircraft radome 3 by the staff. When installing the aircraft radome 3, the positioning post 22 is used to abut against it to prevent the aircraft radome 3 from shifting or misaligning.

[0021] It is worth noting that the casters 2 at the bottom of the lifting platform 1 can be braked at any time, which is existing technology and will not be described in detail.

[0022] By sequentially activating three sets of cylinders 11, the moving blocks 13 are simultaneously moved towards the center of the positioning chamber 14, and the distance between the two sets of clamping blocks 17 is shortened, thus fixing the aircraft radome 3. Then, by operating the motor 8, the first lead screw 7 drives the threaded slider 10 to move to the left, achieving docking between the aircraft radome 3 and the aircraft nose. Compared to traditional devices, this device can not only fix and clamp the outer wall of different models of aircraft radome 3, ensuring that the aircraft radome 3 is centered on the moving platform 9, but also, through the operation of the motor 8, move the aircraft radome 3 to the aircraft nose position, facilitating the installation and removal of the aircraft radome 3 by the staff, reducing the workload and improving work efficiency. The right side of the top of the mobile platform 9 is provided with a second guide groove 19, and a second lead screw 20 is rotatably installed inside the second guide groove 19. A positioning post 22 is movably installed inside the second guide groove 19. The bottom of the positioning post 22 is threadedly connected to the second lead screw 20. A second suction cup 23 is fixedly installed on the top of the positioning post 22. The second suction cup 23 firmly suctions and fixes the right end of the aircraft radome 3. A rotating disk 21 is rotatably installed on the right side of the moving platform 9. The rotating disk 21 is fixedly connected to the second lead screw 20.

[0023] The staff first rotates the rotating disk 21 according to the length of the aircraft radome 3. The rotation of the rotating disk 21 will drive the second lead screw 20 to rotate. The second lead screw 20 will then drive the positioning pin 22, which is threadedly connected to it, to move to the left along the second guide groove 19. After moving to the appropriate position, the staff lifts the aircraft radome 3 to the top of the moving platform 9 and aligns the right end of the aircraft radome 3 with the second suction cup 23 to complete the positioning of the right end of the aircraft radome 3.

[0024] By rotating the rotating disk 21, the second lead screw 20 drives the positioning pin 22, which is threadedly connected to it, to move to the left along the second guide groove 19, further aligning the right end of the aircraft radome 3 with the second suction cup 23, thus completing the positioning of the right end of the aircraft radome 3. Compared with traditional devices, this device can not only position the aircraft radome 3 through the positioning pin 22 and the second suction cup 23, but also prevent the aircraft radome 3 from shifting or misaligning during docking and installation, thus ensuring efficient assembly and disassembly.

[0025] The moving platform 9 has a positioning chamber 14 inside, which is connected to the transverse groove 12. Moving blocks 13 are movably installed on both the front and rear sides inside the positioning chamber 14, and the top of the moving blocks 13 is fixedly connected to the clamping block 17.

[0026] By synchronously displacing the two sets of moving blocks 13, the clamping block 17 is moved toward the center of the positioning chamber 14, ensuring that the aircraft radar dome 3 is located in the center of the moving platform 9.

[0027] The positioning chamber 14 has a gear 16 rotatably mounted in the center, and a rack 15 is fixedly mounted on one end of the moving block 13. Both ends of the gear 16 mesh with the rack 15.

[0028] The operation of cylinder 11 will cause the moving block 13 to move towards the center of positioning chamber 14. Furthermore, the rack 15 at one end of the moving block 13 will drive the gear 16 meshing with it to rotate. At this time, the two sets of moving blocks 13 will move towards the center of positioning chamber 14 synchronously.

[0029] Among them, a cylinder 11 is fixedly installed on the outer wall of the moving platform 9. The telescopic end of the cylinder 11 extends into the positioning chamber 14 and is fixedly connected to one of the moving blocks 13.

[0030] The spacing of the clamping blocks 17 can be adjusted by the operation of the cylinder 11.

[0031] The length of the slider 10 is half that of the first guide groove 5, and the moving stage 9 can extend its left end to the left side of the fixed base 4.

[0032] Among them, the lifting platform 1 is an SJG2-2T scissor lift platform, which is used to lift the aircraft radome 3.

[0033] After the staff moves the lifting platform 1 to a suitable position, they start the lifting platform 1 to raise the aircraft radome 3 to the nose of the aircraft. The lifting platform can bear a load of 2T and can lift radomes that generally do not exceed 1.5T.

[0034] Hydraulic support rods 25 are fixedly installed on both the front and rear sides of the lifting platform 1, and ratchet straps 24 are provided on the top of the moving platform 9. There are two sets of ratchet straps 24, and the two sets of ratchet straps 24 fix the aircraft radar dome 3.

[0035] After securing the aircraft radome 3, workers can use the ratchet strap 24 to fix it onto the moving platform 9. When using the ratchet strap 24, simply pass the strap through the aircraft radome 3, then pass the other end of the strap through the ratchet tensioner. Next, by rotating the ratchet tensioner, the strap is gradually tightened to the desired degree. Finally, ensure that the ratchet locking mechanism is locked to complete the fixing operation. This is a common fixing device for transportation. When lifting the aircraft radome 3, workers can activate the hydraulic support rod 25 to provide stable support and cushioning for the lifting platform 1.

[0036] Working principle and usage process of this utility model: When installing the aircraft radome 3, the operator first rotates the rotating disk 21 according to the length of the radome 3. The rotation of the rotating disk 21 drives the second lead screw 20 to rotate. The second lead screw 20 then drives the positioning pin 22, which is threaded onto it, to move along the second guide groove 19. After moving to the appropriate position, the operator lifts the aircraft radome 3 to the top of the moving platform 9 and aligns the right end of the aircraft radome 3 with the second suction cup 23 to complete the positioning of the right end of the aircraft radome 3. Then, the operator activates the three sets of cylinders 11 in sequence. The operation of the cylinders 11 drives the moving block 13 to move towards the center of the positioning chamber 14. Furthermore, the rack 15 at one end of the moving block 13 drives the gear 16 meshing with it to rotate. At this time, the two sets of moving blocks 13 move towards the center of the positioning chamber 14 synchronously, and the distance between the two sets of clamping blocks 17 shortens, making... The first suction cup 18 supports and fixes the outer wall of the aircraft radome 3. After fixing, the front and rear clamping blocks 17 move synchronously, so that the aircraft radome 3 is located in the center of the moving platform 9, which facilitates the subsequent docking of the aircraft radome 3 with the aircraft. Then, the staff moves the lifting platform 1 to a suitable position and starts the lifting platform 1, so that the aircraft radome 3 is lifted to the nose position of the aircraft. Then the motor 8 is started. The operation of the motor 8 drives the first lead screw 7 to rotate. The first lead screw 7 further drives the slider 10, which is threaded with it, to move to the left, so that the moving platform 9 moves to the left side of the fixed seat 4. Further, the aircraft radome 3 is moved to the nose position of the aircraft, which facilitates the installation and removal of the aircraft radome 3 by the staff. When installing the aircraft radome 3, the positioning post 22 is used to abut against it to prevent the aircraft radome 3 from shifting or misaligning.
