Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 like Figure 1 As shown in the figure, an embodiment of the present invention provides a towing and lifting vehicle based on airborne radar assembly. A lead screw seat 8 is fixedly connected to the side surface of the reinforcing beam 1. A lead screw 9 is provided in the lead screw seat 8. An angular contact bearing 6 is fixedly connected to the side surface of the lead screw 9. A bearing adapter plate 5 is fixedly connected to the side surface of the reinforcing beam 1. The side surface of the angular contact bearing 6 is fixedly connected to the bearing adapter plate 5. A handwheel 7 is provided on the lead screw 9.

[0024] It should be noted that the reinforced beam 1 is the core bearing frame of the device, and the side surface thereof is rigidly connected with the screw rod seat 8, so that the screw rod seat 8 can stably bear the axial load in the lifting process of the radar 2 and provide a stable foundation for subsequent driving of the screw rod 9. The screw rod seat 8 is provided with an internal thread matched with the screw rod 9 at the center, and the screw rod 9 and the screw rod seat 8 form a threaded transmission mechanism to adjust the height of the radar 2. The height of the radar 2 is adjusted by the hand wheel 7 and the screw rod 9, which is the prior art and meets the height alignment requirement of the connection position under the aircraft belly. The side surface of the screw rod 9 is fixedly connected with the angular contact bearing 6, and the side surface of the angular contact bearing 6 is fixedly connected with the bearing adapter plate 5 fixedly connected with the side surface of the reinforced beam 1. This structure converts the point contact of the screw rod 9 and the surrounding structure into surface contact, greatly improves the stability of the screw rod 9 in the lifting process, avoids the deviation of the radar 2 caused by the shaking of the screw rod 9, and ensures the alignment accuracy of the connection position with the aircraft.

[0025] The side surface of the reinforced beam 1 is fixedly connected with the flange bushing 4 and the flange seat 14, and the inside of the flange bushing 4 is provided with a limiting rod 3.

[0026] It should be noted that the reinforced beam 1 is the core bearing frame of the device, and the side surface thereof is rigidly connected with the flange bushing 4 and the flange seat 14 through welding, and the two are symmetrically arranged along the length direction of the reinforced beam 1, so that the limiting rod 3 can remain vertical after being installed, thereby providing a structural basis for lifting guidance. The inner hole size of the flange bushing 4 is matched with the outer diameter of the limiting rod 3, the limiting rod 3 penetrates the inside of the flange bushing 4 and can slide axially along the inner hole of the bushing, and the movement track of the limiting rod 3 is constrained through the guiding action of the flange bushing 4, thereby preventing the radial deviation of the limiting rod 3 during lifting.

[0027] The lower surface of the limiting rod 3 is fixedly connected with a rubber pad 11.

[0028] It should be noted that the lower surface of the limiting rod 3 is fixedly connected with the rubber pad 11 by adhesion, and the rubber pad 11 is made of wear-resistant and elastic material. The rubber pad 11 can prevent the limiting rod 3 from being directly in contact with the ground and causing wear, and can also reduce the impact of the device when it is parked or lifted into place through the buffering characteristics of rubber.

[0029] The inside of the reinforced beam 1 is provided with the radar 2.

[0030] It should be noted that the reinforced beam 1 forms a square trailer frame, and the radar 2 is placed on the bearing plane inside the frame, so that the radar 2 is always in the central area of the frame during towing and lifting, thereby avoiding deviation of the alignment position with the aircraft. The reinforced beam 1 is made of high-strength section material and can stably support the weight of the radar 2.

[0031] A movable rod 15 is provided on the reinforcing beam 1. One end of the movable rod 15 is hinged to the adjacent reinforcing beam 1 via a bushing hinge 12, and the other end is detachably connected to the reinforcing beam 1 via a butterfly lock 13.

[0032] It should be noted that one end of the movable rod 15 is hinged to the adjacent reinforcing beam 1 via a bushed hinge 12. The bushed hinge 12 includes a hinge shaft and a hinge bushing. The hinge bushing is fixedly sleeved on the outside of the hinge shaft. The end of the movable rod 15 is welded and fixed to one end of the hinge shaft, and the end of the adjacent reinforcing beam 1 is welded and fixed to the other end of the hinge shaft. The axis of the hinge shaft is perpendicular to the length direction of the reinforcing beam 1, ensuring that the movable rod 15 can rotate horizontally around the hinge shaft, providing structural support for the opening and closing function of the frame. The other end of the movable rod 15 is detachably connected to the opposite reinforcing beam 1 via a butterfly latch 13. The latch body of the butterfly latch 13 is fixed to the end of the movable rod 15, and the latch tongue is correspondingly fixed to the corresponding position on the opposite reinforcing beam 1. By rotating the operating handle of the butterfly latch 13, the latch body and the latch tongue can be quickly engaged or disengaged without additional tools, which is suitable for the rapid assembly requirements of airport field applications.

[0033] Example 2 like Figures 1-5 As shown, this embodiment 2 is basically the same as embodiment 1, and the similarities will not be repeated. The difference is that it includes a reinforcing beam 1, and an adjustment component 16 is fixedly connected to the lower surface of the reinforcing beam 1. The adjustment component 16 is used to adjust the spatial position of the universal wheel 10 to change the wheel spacing and center of gravity distribution of the equipment.

[0034] It should be noted that the adjustment component 16 is fixedly connected to the lower surface of the reinforcing beam 1. This connection position has been load-bearing calculated to ensure that the adjustment component 16 can stably bear the total weight of the radar 2, the reinforcing beam 1, and its own structure, while preventing deformation of the reinforcing beam 1 due to localized stress concentration, thus providing a stable foundation for subsequent position adjustment of the casters 10. The adjustment component 16 has no relative displacement when driving the casters 10, and it is also convenient for subsequent component maintenance. At the same time, the installation position of the adjustment component 16 is compatible with the frame structure of the reinforcing beam 1, covering the adjustment stroke of the casters 10, ensuring that the wheel track adjustment range can meet the passage requirements of different road conditions such as gravel roads and spliced ​​steel plate roads in the airport. The adjustment component 16 changes the wheel track by adjusting the spatial position of the casters 10. When facing uneven road surfaces such as gravel roads or spliced ​​steel plate roads outside the airport, the wheel track can be increased by adjusting the component 16 to improve the overall support stability of the equipment and avoid the radar 2 from shaking due to road bumps. When transferring in narrow passages in the hangar, the wheel track can be reduced to improve turning flexibility and meet the passability requirements in different scenarios, thereby improving the applicability range of the equipment.

[0035] The adjusting assembly 16 adjusts the gravity center distribution of the equipment by changing the spatial position of the universal wheel 10. When the radar 2 is assembled and assisted, the universal wheel 10 is adjusted inward to make the gravity center close to the center of the equipment, avoid stress concentration of the wheel shaft or chassis, and prevent structural deformation. When the load is light, the universal wheel 10 is extended outward to make the gravity center move downward and be more evenly distributed. Especially in the temporary loading scene of manual assistance docking of the radar 2 antenna and unilateral short-time load increase, the gravity center deviation can be corrected by adjusting the universal wheel 10 through the adjusting assembly 16 to avoid unilateral inclination of the equipment and ensure the alignment accuracy of the connection part between the radar 2 and the aircraft.

[0036] The adjusting assembly 16 includes a mounting seat 1606. The adjusting assembly 16 includes a fixed rod 1601, the lower surface of the reinforcing beam 1 is fixedly connected with the fixed rod 1601, a groove 1602 is formed in the inner part of the fixed rod 1601, a two-way screw rod 1604 is threadedly connected with the inner surface of the groove 1602, a driving motor 1603 is fixedly connected with the left surface of the fixed rod 1601, the output end of the driving motor 1603 is fixedly connected with the two-way screw rod 1604, a sliding block 1605 is threadedly connected with the side surface of the two-way screw rod 1604, the side surface of the sliding block 1605 is fixedly connected with the mounting seat 1606, the inner wall of the mounting seat 1606 is fixedly connected with the universal wheel 10, and the side surface of the screw rod seat 8 is provided with the controller 20.

[0037] It should be noted that the groove 1602 formed in the inner part of the fixed rod 1601 provides installation space for the two-way screw rod 1604, the inner surface of the groove 1602 is processed with internal threads matched with the two-way screw rod 1604, and the length of the groove 1602 is designed to cover the effective transmission stroke of the two-way screw rod 1604. The driving motor 1603 is fixed on the left surface of the fixed rod 1601 by bolts, and the output end thereof is rigidly connected with one end of the two-way screw rod 1604 by a shaft coupling, so that the torque of the driving motor 1603 can be stably transmitted to the two-way screw rod 1604, the two-way screw rod 1604 is reversely driven, and a power source is provided for the position adjustment of the universal wheel 10. A protective cover is arranged on the outer side of the driving motor 1603 to protect it. A lithium battery is arranged on the fixed rod 1601, the driving motor 1603 is electrically connected with the lithium battery and the controller 20, the inner hole of the sliding block 1605 is processed with internal threads matched with the two-way screw rod 1604, and the sliding block 1605 is sleeved on the side surface of the two-way screw rod 1604 by thread connection. The side surface of the sliding block 1605 is fixed with the mounting seat 1606 by bolts, and the inner wall of the mounting seat 1606 is rotatably connected with the universal wheel 10 by a bearing. During use, the driving motor 1603 is started to drive the two-way screw rod 1604 to rotate, and the two groups of sliding blocks 1605, the mounting seat 1606 and the universal wheel 10 on the two-way screw rod 1604 move in opposite directions.

[0038] The upper surface of the mounting seat 1606 is fixedly connected with a fourth contact plate 19, and the lower surface of the reinforcing beam 1 is fixedly connected with a fixed box 17. The fixed box 17 is internally provided with a multi-gear damping adaptation assembly 18 for providing damping buffers with different rigidities to adapt to different loads and road conditions. The multi-gear damping adaptation assembly 18 includes a first damper 1801, a second damper 1803 and a third damper 1805. The rigidity of the first damper 1801, the second damper 1803 and the third damper 1805 decreases in turn. The top ends of the first damper 1801, the second damper 1803 and the third damper 1805 are fixedly connected with the top inner wall of the fixed box 17. The bottom ends are respectively connected with a first contact plate 1802, a second contact plate 1804 and a third contact plate 1806.

[0039] It should be noted that the mounting seat 1606 serves as a bearing base of the universal wheel 10. The mounting seat 1606 is rigidly connected with the fourth contact plate 19, and the connection position ensures that the surface of the fourth contact plate 19 remains horizontal. When the mounting seat 1606 drives the universal wheel 10 to adjust the position, the fourth contact plate 19 can be synchronously translated to provide a stable movement basis for subsequent contact with the multi-gear damping adaptation assembly 18, and to ensure uniformity of stress during contact and avoid local stress concentration to cause damage to components. The top ends of the first damper 1801, the second damper 1803 and the third damper 1805 in the multi-gear damping adaptation assembly 18 are fixedly connected with the top inner wall of the fixed box 17, and the three are uniformly arranged along the length direction of the fixed box 17. The spacing matches the movement stroke of the fourth contact plate 19 to ensure that the fourth contact plate 19 can be accurately connected with the contact plates at the bottom ends of different dampers when the mounting seat 1606 moves. Meanwhile, the bottom ends of the three dampers are respectively connected with the first contact plate 1802, the second contact plate 1804 and the third contact plate 1806. The surface size of the contact plate is adapted to the fourth contact plate 19 to ensure the effective stress area when the two are in contact and to improve the damping buffer effect.

[0040] The core function of the application is to realize accurate lifting during the whole process of installing and dismounting the airborne test radar 2 with a diameter of 800 mm, a height of 420 mm and a weight of 50 kg. When the radar 2 is in a heavy load state, such as bearing the body weight of 50 kg or exceeding the rated load by 10%-20%, that is, the maximum load reaches 60 kg, or the device travels on the rough road of the airport outside field, the deep pit and other bad road conditions, the fourth contact plate 19 driven by the mounting seat 1606 is connected with the first contact plate 1802 at the bottom end of the first damper 1801. Relying on the high rigidity characteristics of the first damper 1801, the overload impact and strong bumping of the road are dispersed, and the single-point stress concentration and structural deformation of the axle or chassis are prevented. When the radar 2 parts close to the rated load are transported, such as the signal processing unit with medium weight, or the device travels on the transition road with slight splicing joints and small protrusions, the fourth contact plate 19 is connected with the second contact plate 1804, and the moderate rigidity of the second damper 1803 absorbs the secondary impact through moderate elastic deformation, which not only avoids the transmission of too much vibration by the high-rigidity damper to affect the radar 2, but also prevents the shaking caused by insufficient support of the weak-rigidity damper. When the device is lightly loaded, such as empty or only bearing a small amount of assembly tools, or travels on the flat road of the hangar hardened ground, the fourth contact plate 19 is connected with the third contact plate 1806, and the weak rigidity of the third damper 1805 can accurately filter the high-frequency micro-vibration of the road, thereby ensuring the micro-motion stability of the radar 2 antenna array and other precision components. When the mounting seat 1606 adjusts the position of the universal wheel 10, the fourth contact plate 19 moves synchronously with the mounting seat 1606, and can be automatically connected with the contact plate of the corresponding damper without additional manual operation. Moreover, the two groups of driving motors 1603 are used synchronously during use.

[0041] One end of the fourth contact plate 19 is provided with a bevel structure, and the other end is provided with a circular arc transition structure. The bevel structure realizes gentle contact with the multi-gear damping adaptive assembly 18, and the circular arc transition structure avoids scratching and jamming during reverse movement.

[0042] It should be noted that the bevel and the circular end ensure that the fourth contact plate 19 can realize gentle transition contact with the corresponding contact plate through the bevel and the circular surface when the mounting seat 1606 moves to different dampers, thereby avoiding vertical collision.

[0043] The side surface of the reinforced beam 1 is fixedly connected with a connecting plate 21, the upper surface of the connecting plate 21 is fixedly connected with an air cylinder 22, and the output end of the air cylinder 22 is fixedly connected with a support plate 23.

[0044] It should be noted that the connecting plate 21 is fixedly connected with the side surface of the reinforcing beam 1 by welding, the connecting position is selected in the load supporting area of the reinforcing beam 1, the plate surface of the connecting plate 21 is kept horizontal, and the output end can be vertically lifted after the subsequent installation of the cylinder 22. The support plate 23 is lifted and tightly pressed against the ground by the extension and retraction of the output end of the cylinder 22, and then the whole device is supported, so that the universal wheel 10 is temporarily separated from the ground or the contact pressure with the ground is reduced. The spatial position of the universal wheel 10 is adjusted by the adjusting assembly 16 to change the track, adapt to different road conditions and loads, so that the universal wheel 10 is not tightly attached to the ground due to the weight of the device or the pressure of the radar 2, and the adjusting is not stuck or the adjusting assembly 16 is overloaded and damaged.

[0045] Working principle: when using, the use position of the universal wheel 10 is adjusted according to different road conditions and use scenes, the device is lifted by moving the support plate 23 driven by the cylinder 22 before starting, so that the universal wheel 10 is not in contact with the ground, the driving motor 1603 is started to drive the bidirectional screw 1604 to rotate, and the two groups of sliding blocks 1605, mounting seats 1606, fourth contact plates 19 and fourth contact plates 19 on the bidirectional screw 1604 move to the two ends or center in opposite directions, when the fourth contact plate 19 contacts the first contact plate 1802, the first damper 1801 is used for buffering, which is suitable for non-flat road surface dragging and heavy load working conditions such as airport off-site gravel road, deep pit and protrusion. When the fourth contact plate 19 contacts the second contact plate 1804, the second damper 1803 is used for buffering, which is suitable for medium load and transition road conditions, such as the device only carrying radar 2 signal processing unit and other accessories or moving on the transition road surface between hangar and off-site. When the fourth contact plate 19 contacts the third contact plate 1806, the second contact plate 1804 is used for buffering, which is suitable for light load working conditions and flat road conditions.
