Description

Technical Field

[0001] This invention relates to the field of mechanical engineering technology, and in particular to an assembly and towing lift based on airborne radar. Background Technology

[0002] Airborne radar assembly and transport elevators are core auxiliary equipment in the field of mechanical engineering and aviation maintenance. They are mainly used in airport hangars, field support and other scenarios to realize the transfer and assembly of radars. Their mobility and load adaptability directly affect the radar assembly efficiency and component safety. They are key equipment to ensure rapid maintenance of airborne radars and improve equipment uptime.

[0003] Currently, airborne radar assembly and transport vehicles use a fixed wheelbase and a single damping structure. The damping structure absorbs road bumps, and the lifting mechanism is used to adjust the height of the radar components and align them for assembly. However, the fixed wheel position makes the equipment unable to cope with various road conditions. On uneven surfaces such as temporary gravel roads and spliced ​​steel plate roads outside the airport, the fixed wheelbase and single damping are difficult to balance impact resistance and stability, and the radar components are prone to shaking due to road bumps. Furthermore, it cannot adapt to different load conditions. When the radar components exceed the rated load, the fixed wheelbase and single damping cannot disperse the overload impact, which can easily cause stress concentration at a single point on the axle or chassis and structural deformation. When transporting light loads, the fixed wheelbase provides insufficient stability.

[0004] Therefore, to address the above shortcomings, it is necessary to provide a towing and lifting vehicle based on airborne radar assembly, which solves the problems of existing equipment having fixed wheel positions, being prone to shaking on uneven surfaces such as gravel roads and spliced ​​steel plate roads outside the airport, having single-point stress concentration on the wheel axle under heavy loads, and having insufficient stability of the fixed wheel track under light loads. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an airborne radar-based assembly and towing lift vehicle, which addresses the deficiencies in the prior art.

[0006] To address the aforementioned technical problems, this invention provides an airborne radar-based assembly and towing lift vehicle, comprising a reinforcing beam. An adjustment component is fixedly connected to the lower surface of the reinforcing beam. This adjustment component is used to adjust the spatial position of the casters to change the wheelbase and center of gravity distribution of the equipment. The adjustment component includes a mounting base, with a fourth contact plate fixedly connected to the upper surface of the mounting base. A fixed box is fixedly connected to the lower surface of the reinforcing beam. A multi-stage damping adapter component is installed inside the fixed box. This multi-stage damping adapter component provides damping buffers of different rigidities to adapt to different loads and road conditions. One end of the fourth contact plate has a beveled structure, and the other end has a rounded transition structure. The beveled structure achieves smooth contact with the multi-stage damping adapter component, while the rounded transition structure avoids scraping and jamming during reverse movement, thus completing a progressive contact and engagement with the multi-stage damping adapter component.

[0007] Preferably, the adjusting assembly includes a fixed rod, the lower surface of the reinforcing beam is fixedly connected to the fixed rod, the fixed rod has a groove inside, the inner surface of the groove is threaded with a bidirectional lead screw, the left surface of the fixed rod is fixedly connected to a drive motor, and the output end of the drive motor is fixedly connected to the bidirectional lead screw.

[0008] Preferably, the side surface of the bidirectional lead screw is threaded with a slider, the side surface of the slider is fixedly connected to the mounting base, and the inner wall of the mounting base is fixedly connected with a caster wheel.

[0009] Preferably, the multi-position damping adapter assembly includes a first damper, a second damper, and a third damper, the rigidity of which decreases sequentially. The top ends of the first damper, the second damper, and the third damper are all fixedly connected to the inner top wall of the fixed box, and the bottom ends are respectively connected to a first contact plate, a second contact plate, and a third contact plate.

[0010] Preferably, a lead screw seat is fixedly connected to the side surface of the reinforcing beam, a lead screw is fitted inside the lead screw seat, an angular contact bearing is fixedly connected to the side surface of the lead screw, a bearing adapter plate is fixedly connected to the side surface of the reinforcing beam, and the side surface of the angular contact bearing is fixedly connected to the bearing adapter plate.

[0011] Preferably, a flange bushing and a flange seat are fixedly connected to the side surface of the reinforcing beam, a limit rod is provided through the inside of the flange bushing, and a rubber pad is fixedly connected to the lower surface of the limit rod.

[0012] Preferably, a radar is installed inside the reinforcing beam, and a controller is installed on the side surface of the lead screw seat.

[0013] Preferably, the reinforcing beam is provided with a movable rod, one end of which is hinged to the adjacent reinforcing beam via a bushing hinge, and the other end is detachably connected to the reinforcing beam via a butterfly lock.

[0014] Preferably, a handwheel is provided on the lead screw.

[0015] Preferably, a connecting plate is fixedly connected to the side surface of the reinforcing beam, a cylinder is fixedly connected to the upper surface of the connecting plate, and a support plate is fixedly connected to the output end of the cylinder.

[0016] Implementing this invention has the following beneficial effects: 1. This invention, through the setting of adjustment components, multi-position damping adaptation components, and a fourth contact plate, allows for flexible adjustment of the omnidirectional wheel's position, enabling selective contact with three sets of different rigid dampers. This creates a single wheel with multiple modes of adaptation, improving passability in complex road conditions. When facing uneven road surfaces such as gravel roads and spliced ​​steel plate roads outside airports, the omnidirectional wheel's position can be adjusted in conjunction with the high-rigidity damping on the inner side, leveraging its strong impact resistance to balance stability under complex road conditions and prevent radar components from shaking due to bumps. For heavy-load scenarios where radar components exceed their rated load, the omnidirectional wheel retracts and fits against the high-rigidity damping, dispersing overload impacts to the overall frame and preventing stress concentration and structural deformation at single points on the axle or chassis.

[0017] 2. When handling lightly loaded transport, the omnidirectional wheels extend outwards in conjunction with the outermost weak rigid damping. By widening the wheelbase, the instability of a fixed wheelbase is compensated, preventing the equipment from being top-heavy. This effectively filters out minor road bumps, ensuring the micro-motion stability of the radar's precision components and significantly expanding the equipment's applicable operating conditions. When transporting radar components with a medium rated load or traveling on transitional road conditions with slight seams or bumps, the omnidirectional wheels can be adjusted to the middle position to match the medium rigid damping of the middle layer. Through moderate elastic deformation, secondary impacts are absorbed, preventing excessive vibration from being transmitted by the high rigid damping and affecting the components, while also preventing insufficient support from the weak rigid damping that could cause swaying.

[0018] 3. The universal wheel movement of this invention can synchronously realize the dynamic adaptation of the equipment's center of gravity. In the face of temporary local loading scenarios during the assembly of radar components, such as when manually assisting in docking the radar antenna, the load on one side increases for a short time. The universal wheel can be extended to adjust the center of gravity in real time, avoiding the equipment from tilting on one side due to a sudden increase in local load, and ensuring the alignment accuracy of the radar components during the assembly process.

[0019] 4. In this invention, the first contact plate, second contact plate, third contact plate, and fourth contact plate are designed with one end beveled and the other end rounded. This allows the contact plates to make progressive contact when the universal wheel position is adjusted, avoiding the impact load generated by rigid collisions during damping switching. This prevents displacement of precision radar components due to instantaneous vibration. The rounded corners reduce friction and wear between the contact plates, lowering the risk of jamming after long-term use and ensuring a smooth and stable damping switching process. At the same time, it avoids stress concentration caused by frequent contact, which can lead to component fatigue damage. This further improves the durability and fitting accuracy of the multi-position damping adapter component. Attached Figure Description

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 reinforcing beam 1, as the core load-bearing frame of the equipment, has its side surface rigidly fixedly connected to the lead screw seat 8. This ensures that the lead screw seat 8 can stably withstand the axial load during the lifting and lowering of the radar 2, providing a stable foundation for the subsequent transmission of the lead screw 9. The center of the lead screw seat 8 has an internal thread adapted to the lead screw 9. The two work together to form a threaded transmission mechanism to achieve radar 2 height adjustment. Adjusting the radar 2 height via the handwheel 7 and the lead screw 9 is a current technology, meeting the height alignment requirements for the connection position under the aircraft fuselage. An angular contact bearing 6 is fixedly connected to the side surface of the lead screw 9, and a bearing adapter plate 5 is fixedly connected to the side surface of the reinforcing beam 1, with the side surface of the angular contact bearing 6 fixedly connected to the bearing adapter plate 5. This structure transforms the point contact between the lead screw 9 and the surrounding structure into surface contact, significantly improving the stability of the lead screw 9 during lifting and lowering, preventing radar 2 from shifting due to lead screw 9 wobbling, and ensuring the alignment accuracy of the connection point with the aircraft.

[0025] The side surface of the reinforcing beam 1 is fixedly connected to a flange bushing 4 and a flange seat 14, and a limit rod 3 is installed through the inside of the flange bushing 4.

[0026] It should be noted that the reinforcing beam 1 is the core of the equipment's load-bearing frame. Its side surface is rigidly fixed to the flange bushing 4 and flange seat 14 by welding. Both are symmetrically arranged along the length of the reinforcing beam 1 to ensure that the limiting rod 3 remains vertical after installation, providing a structural foundation for lifting and guiding. The inner diameter of the flange bushing 4 matches the outer diameter of the limiting rod 3. The limiting rod 3 penetrates the flange bushing 4 and can slide axially along the inner hole of the bushing. Through the guiding action of the flange bushing 4, the movement trajectory of the limiting rod 3 is constrained, preventing radial deviation during lifting and lowering.

[0027] A rubber pad 11 is fixedly connected to the lower surface of the limiting rod 3.

[0028] It should be noted that the lower surface of the limit rod 3 is fixed with a rubber pad 11 by adhesive bonding. The rubber pad 11 is made of wear-resistant and elastic material. Its function is to prevent the limit rod 3 from directly contacting the ground and causing wear. At the same time, the buffering properties of rubber reduce the impact when the equipment is parked or raised to the correct position.

[0029] Radar 2 is installed inside the reinforcing beam 1.

[0030] It should be noted that the reinforcing beam 1 encloses and forms a square trailer frame, and the radar 2 is placed on the load-bearing plane inside the frame to ensure that the radar 2 is always in the center area of ​​the frame during towing and lifting, so as to avoid misalignment of the connection part with the aircraft due to offset. The reinforcing beam 1 is made of high-strength profile to 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 Figure 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 adjustment component 16 adjusts the center of gravity distribution of the equipment by changing the spatial position of the casters 10. When the radar 2 is under heavy load or when assembling auxiliary tools, the casters 10 can be adjusted inward to bring the center of gravity closer to the center of the equipment, avoiding stress concentration at a single point on the axle or chassis and preventing structural deformation. When under light load, the casters 10 can be extended outward to lower the center of gravity and make the distribution more even. Especially in temporary loading scenarios such as manually assisted docking of the radar 2 antenna or short-term increase in load on one side, the adjustment component 16 can adjust the casters 10 to correct the center of gravity deviation, avoid unilateral tilting of the equipment, and ensure the alignment accuracy of the connection between the radar 2 and the aircraft.

[0036] The adjustment assembly 16 includes a mounting base 1606 and a fixed rod 1601. The lower surface of the reinforcing beam 1 is fixedly connected to the fixed rod 1601. A groove 1602 is provided inside the fixed rod 1601. A bidirectional lead screw 1604 is threadedly connected to the inner surface of the groove 1602. A drive motor 1603 is fixedly connected to the left surface of the fixed rod 1601. The output end of the drive motor 1603 is fixedly connected to the bidirectional lead screw 1604. A slider 1605 is threadedly connected to the side surface of the bidirectional lead screw 1604. The side surface of the slider 1605 is fixedly connected to the mounting base 1606. A caster wheel 10 is fixedly connected to the inner wall of the mounting base 1606. A controller 20 is provided on the side surface of the lead screw seat 8.

[0037] It should be noted that the groove 1602 inside the fixing rod 1601 provides installation space for the double-acting lead screw 1604. The inner surface of the groove 1602 is machined with an internal thread that matches the double-acting lead screw 1604, and the length of the groove 1602 is designed to cover the effective transmission stroke of the double-acting lead screw 1604. The drive motor 1603 is fixed to the left surface of the fixing rod 1601 by bolts, and its output end is rigidly connected to one end of the double-acting lead screw 1604 by a coupling, ensuring that the torque of the drive motor 1603 can be stably transmitted to the double-acting lead screw 1604, realizing the forward and reverse drive of the lead screw and providing a power source for the position adjustment of the caster wheel 10. The drive motor 1603 is protected by a protective cover. A lithium battery is installed on the fixing rod 1601. The drive motor 1603 is electrically connected to the lithium battery and the controller 20. The inner hole of the slider 1605 is machined with an internal thread that matches the double-acting screw 1604. It is threaded and sleeved on the side surface of the double-acting screw 1604. The side surface of the slider 1605 is fixed to the mounting base 1606 by bolts. The inner wall of the mounting base 1606 is rotatably connected to the universal wheel 10 through a bearing. In use, the drive motor 1603 is started to drive the double-acting screw 1604 to rotate. The two sets of sliders 1605, mounting base 1606 and universal wheel 10 on the double-acting screw 1604 move in opposite directions.

[0038] The upper surface of the mounting base 1606 is fixedly connected to the fourth contact plate 19, and the lower surface of the reinforcing beam 1 is fixedly connected to the fixing box 17. The fixing box 17 is equipped with a multi-stage damping adapter assembly 18. The multi-stage damping adapter assembly 18 is used to provide damping buffers with different stiffnesses to adapt to different loads and road conditions. The multi-stage damping adapter assembly 18 includes a first damper 1801, a second damper 1803, and a third damper 1805. The stiffness of the first damper 1801, the second damper 1803, and the third damper 1805 decreases sequentially. The top ends of the first damper 1801, the second damper 1803, and the third damper 1805 are all fixedly connected to the top inner wall of the fixing box 17, and the bottom ends are respectively connected to the first contact plate 1802, the second contact plate 1804, and the third contact plate 1806.

[0039] It should be noted that the mounting base 1606 serves as the load-bearing base for the caster wheel 10. It is rigidly fixed to the fourth contact plate 19, and the connection position ensures that the surface of the fourth contact plate 19 remains horizontal. When the mounting base 1606 moves the caster wheel 10 to adjust its position, it can simultaneously move the fourth contact plate 19 to translate, providing a stable motion basis for subsequent contact and cooperation with the multi-position damping adapter component 18. At the same time, it ensures the uniformity of force during contact and avoids local stress concentration that could lead to component damage. The first damper 1801, the second damper 1803, and the third damper 1805 in the multi-position damping adapter assembly 18 are all fixedly connected to the top inner wall of the fixed box 17 at their top ends, and the three are evenly arranged along the length of the fixed box 17 with a spacing that matches the travel of the fourth contact plate 19. This ensures that when the fourth contact plate 19 moves with the mounting base 1606, it can accurately mate with the contact plates at the bottom of different dampers. At the same time, the bottom ends of the three dampers are respectively connected to the first contact plate 1802, the second contact plate 1804, and the third contact plate 1806. The plate surface size of the contact plate is adapted to the fourth contact plate 19 to ensure the effective force-bearing area when the two are in contact, thereby improving the damping and buffering effect.

[0040] The core function of this invention is to precisely lift the airborne test radar 2, which has a diameter of 800mm, a height of 420mm, and a weight of 50kg, during the entire installation and disassembly process. When the radar 2 is under heavy load, such as bearing the weight of 50kg, or exceeding the rated load by 10%-20% (i.e., the maximum load reaches 60kg), or when the equipment is traveling on rough roads such as gravel roads and deep pits outside the airport, the mounting base 1606 drives the fourth contact plate 19 to connect with the first contact plate 1802 at the bottom of the first damper 1801. Relying on the high rigidity of the first damper 1801, the overload impact and strong road bumps are strongly dispersed, preventing stress concentration and structural deformation at a single point on the axle or chassis. When transporting radar 2 components close to the rated load, such as signal processing equipment of medium weight... When the unit is in operation, or traveling on transitional road conditions with slight seams or small bumps, the fourth contact plate 19 engages with the second contact plate 1804. The moderate rigidity of the second damper 1803 absorbs secondary impacts through moderate elastic deformation, preventing excessive vibration transmission from the high-rigidity damper and its impact on the radar 2, while also preventing insufficient support from the weak-rigidity damper that could cause swaying. When the equipment is lightly loaded, such as when unloaded or carrying only a few assembly tools, or traveling on flat road conditions such as hardened surfaces in a hangar, the fourth contact plate 19 engages with the third contact plate 1806. The weak rigidity of the third damper 1805 can precisely filter high-frequency micro-vibrations from the road surface, ensuring the micro-motion stability of precision components such as the radar 2 antenna array. When the adjustment component 16 drives the mounting base 1606 to adjust the position of the caster wheel 10, the fourth contact plate 19 moves synchronously with the mounting base 1606, automatically engaging with the contact plate of the corresponding damper without additional manual operation. Furthermore, both sets of drive motors 1603 operate synchronously during use.

[0041] The fourth contact plate 19 has a beveled structure at one end and a rounded transition structure at the other end. The beveled structure enables smooth contact with the multi-position damping adapter 18, and the rounded transition structure prevents scraping and jamming during reverse movement.

[0042] It should be noted that the inclined and rounded ends are designed to ensure that when the fourth contact plate 19 moves with the mounting base 1606 to different dampers, it can achieve a smooth transition contact with the corresponding contact plate through the inclined and rounded ends, thus avoiding vertical collisions.

[0043] A connecting plate 21 is fixedly connected to the side surface of the reinforcing beam 1, a cylinder 22 is fixedly connected to the upper surface of the connecting plate 21, and a support plate 23 is fixedly connected to the output end of the cylinder 22.

[0044] It should be noted that the connecting plate 21 is fixedly connected to the side surface of the reinforcing beam 1 by welding. The connection position is selected in the load-bearing area of ​​the reinforcing beam 1, and the surface of the connecting plate 21 is kept horizontal to ensure that the output end can be vertically raised and lowered after the cylinder 22 is installed. The extension and retraction of the output end of the cylinder 22 drives the support plate 23 to rise and press against the ground, thereby supporting the entire equipment and temporarily lifting the casters 10 off the ground or reducing the contact pressure with the ground. The spatial position of the casters 10 can be adjusted by adjusting the component 16 to change the wheel track and adapt to different road conditions and loads, avoiding the casters 10 from being too tightly pressed against the ground due to the weight of the equipment or the pressure of the radar 2, which could cause adjustment jamming or overload damage to the adjustment component 16.

[0045] Working principle: When in use, the position of the caster wheel 10 is adjusted according to different road conditions and usage scenarios. Before adjustment, the start cylinder 22 drives the support plate 23 to move and lift the equipment so that the caster wheel 10 does not contact the ground. The start drive motor 1603 drives the double-acting screw 1604 to rotate. The two sets of sliders 1605, mounting base 1606, and fourth contact plate 19 on the double-acting screw 1604 move in opposite directions to both ends or the center. When the fourth contact plate 19 contacts the first contact plate 1802, it is buffered by the first damper 1801. It is suitable for towing and heavy-load conditions on gravel roads, uneven roads with deep potholes and protrusions outside the airport. When the fourth contact plate 19 contacts the second contact plate 1804, it is buffered by the second damper 1803, which is suitable for medium load and transitional road conditions, such as when the equipment only carries accessories such as the radar 2 signal processing unit or moves on the transitional road surface connecting the hangar and the field. When the fourth contact plate 19 contacts the third contact plate 1806, it is buffered by the second contact plate 1804, which is suitable for light load conditions and flat road conditions.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

The lower surface of the reinforcing beam (1) is fixedly connected to a fixing box (17). The fixing box (17) is internally equipped with a multi-stage damping adapter assembly (18). The multi-stage damping adapter assembly (18) is used to provide damping buffers with different stiffnesses to adapt to different loads and road conditions. The fourth contact plate (19) is used to adjust the spatial position of the casters (10) to change the wheelbase and center of gravity distribution of the equipment. One end of the contact plate (19) is provided with a bevel structure, and the other end is provided with a rounded transition structure. The bevel structure enables smooth contact with the multi-position damping adapter component (18), and the rounded transition structure avoids scraping and jamming during reverse movement, thus completing the progressive contact and cooperation with the multi-position damping adapter component (18). When the mounting base (1606) drives the universal wheel (10) to adjust its position, it simultaneously drives the fourth contact plate (19) to move horizontally. When the adjustment component (16) drives the mounting base (1606) to adjust the position of the universal wheel (10), the fourth contact plate (19) moves synchronously with the mounting base (1606) and automatically docks with the contact plate of the corresponding damper without the need for additional manual operation.
