Description

Technical Field

[0001] The present invention belongs to the technical field of aircraft maintenance, and specifically refers to a device for disassembling, installing, lifting and supporting a radiator for aircraft maintenance. Background Art

[0002] With the development of aviation technology, the structure of aircraft radiators has become increasingly complex and precise, usually consisting of multiple parts, such as three main parts: a core heat dissipation unit, an inlet and outlet liquid pipeline connection part, and a heat dissipation fin assembly. When maintaining and repairing an aircraft radiator, it is often necessary to disassemble it from the aircraft and further separate these three parts for detailed inspection, cleaning, repair or replacement of damaged components.

[0003] Traditional maintenance methods face many challenges during the disassembly and installation of radiators: when disassembling the radiator, there is no suitable device that can stably and accurately lift and support the radiator and adapt to its different shapes and structures, which makes it extremely difficult for maintenance personnel to separate the three parts. This not only increases the labor intensity but also prolongs the maintenance time and reduces the maintenance efficiency. Existing general clamping tools are difficult to closely cooperate with the complex and variable outer contour of the aircraft radiator and cannot provide uniform and stable clamping force. When performing maintenance operations on the radiator, such as disassembling or installing connecting bolts, replacing seals, etc., if the clamping is not firm, the radiator may shift or shake, which will not only affect the accuracy and quality of the maintenance operation but also may lead to safety accidents, such as tool slipping, component dropping, etc., posing a threat to the personal safety of maintenance personnel. Summary of the Invention

[0004] To solve the above problems, the present invention provides a device for disassembling, installing, lifting and supporting a radiator for aircraft maintenance, which can stably and accurately assist in lifting the radiator after disassembling the aircraft radiator, facilitating maintenance personnel to quickly and safely separate the three main parts of the radiator, so that maintenance personnel can perform maintenance operations on the three main parts. By using the gravity of the aircraft radiator to compress gas into the airbag, the airbag has strong deformability, and the airbag realizes adaptive and fitting clamping and fixing of the aircraft radiator, ensuring stability during radiator maintenance. By using a unique electromagnetic control and gas circuit linkage mechanism, the aircraft radiator can be quickly unlocked. Thanks to the design of solenoid valve two with delayed closing, each component can automatically return to its original position in an orderly manner, preparing for the next clamping operation, without complex manual reset operations, reducing the labor intensity of maintenance personnel, and also ensuring the coherence and stability of the device's cyclic use.

The three groups of connecting rod clamping assemblies are respectively arranged on the first support, the second support and the third support. The three groups of pressure inflation fitting assemblies are respectively arranged under the first support, the second support and the third support. The connecting rod clamping assembly is connected to the pressure inflation fitting assembly. The connecting rod clamping assembly includes a moving bracket, a connecting rod and a clamping arm. Slots are penetrated through the top sides of the first support, the second support and the third support. Side groove rails are penetrated through both sides of the first support, the second support and the third support. The moving bracket is slidably arranged in the slot. A contact pressure roller is rotatably arranged in the moving bracket. The bottom end of the clamping arm is hinged in the side groove rail. One end of the connecting rod telescopically slides at the bottom end of the clamping arm. The other end of the connecting rod is hinged to the bottom end of the moving bracket.

The other path is connected to one end of the second solenoid valve. The other ends of the first solenoid valve and the second solenoid valve both have normally open contacts.

[0012] Compared with the prior art, the present invention adopts the above structure to achieve the following beneficial effects:

[0013] 1. After the aircraft radiator is disassembled, it can be stably and accurately assisted in lifting, facilitating the maintenance personnel to quickly and safely separate the three main parts of the aircraft radiator. While moving the two parts at the two outer ends of the three main parts of the aircraft radiator in opposite directions away from the middle part, and then turning to one side, so as to respectively perform maintenance operations on the three main parts of the aircraft radiator, and there is no occlusion between them;

[0014] 2. Utilize the gravity of the aircraft radiator to press down on the contact roller. Under the action of gravity, the contact roller drives the moving bracket to press down. The moving bracket drives the clamping arms on both sides to tighten through the connecting rod, thereby clamping the aircraft radiator. Compress the gas in the first piston cylinder by gravity. The gas in the first piston cylinder is transmitted to the airbag through the first air pipe and to the second piston cylinder through the third air pipe. The piston in the second piston cylinder drives the electromagnetic block away from the magnet under the action of the gas. The airbag has very strong deformability, so the airbag adaptively fits the outer sides of the three main parts of the aircraft radiator. The unique adaptive fitting clamping mechanism can be adjusted and fixed according to the specific shape of the aircraft radiator, making it have a wide range of applications, reducing the cost and management complexity for airlines to equip multiple special maintenance tools for different aircraft models;

[0015] 3. When it is necessary to lift the aircraft radiator, the unique electromagnetic control and air circuit linkage mechanism plays a key role. By switching the switch, using the time delay of the second solenoid valve and the change of the magnetic pole direction of the electromagnetic block, the piston movement in the second piston cylinder and the air circuit flow direction are switched. First, it is in the energy storage preparation stage, and then the air pressure is instantaneously released to push the moving bracket upward, quickly unfolding the clamping arms. At the same time, the airbag quickly exhausts air and becomes flat. The entire unlocking process is rapid and smooth, greatly facilitating the maintenance personnel to remove the radiator from the device and significantly improving the convenience and efficiency of the maintenance operation;

[0016] 4. After completing the operation of removing the radiator, turn the switch back to the initial state. Thanks to the design of the second solenoid valve with delayed closing, each component can automatically return to its original position in an orderly manner. The gas in the first piston cylinder and the second piston cylinder rebalances, and the clamping arms return to the initial open state, preparing for the next clamping operation. There is no need for complex manual reset operations, reducing the labor intensity of the maintenance personnel and ensuring the coherence and stability of the device's cyclic use;

[0017] 5. Through auxiliary lifting and stable clamping, the maintenance personnel do not need to support and fix the aircraft radiator with manpower for a long time, reducing the physical burden on the maintenance personnel. Especially when dealing with heavier aircraft radiators or performing long-term maintenance operations, it can enable the maintenance personnel to maintain a good working state, reduce safety accidents caused by fatigue operations, and at the same time help improve the work enthusiasm and work efficiency of the maintenance personnel;

[0018] 6. During the process of lifting and separating the three parts of the radiator, the device can effectively avoid collisions between the aircraft radiator and surrounding objects caused by improper operation or damage to the internal structure due to uneven force. Precise lifting and stable clamping and fixing can ensure that the aircraft radiator remains in good condition before, during, and after maintenance, thus guaranteeing the maintenance quality and reducing the increase in maintenance costs and potential flight safety hazards caused by secondary damage during the maintenance process.

[0033] The adaptive fitting clamping mechanism 8 includes a connecting rod clamping assembly 81 and a pressure inflation fitting assembly 82. Three sets of the connecting rod clamping assembly 81 are arranged on the first support 51, the second support 61, and the third support 71 respectively. Three sets of the pressure inflation fitting assembly 82 are arranged under the first support 51, the second support 61, and the third support 71 respectively. The connecting rod clamping assembly 81 is connected to the pressure inflation fitting assembly 82. The connecting rod clamping assembly 81 includes a moving bracket 811, a connecting rod 812, and a clamping arm 813. Slots 814 penetrate through the top sides of the first support 51, the second support 61, and the third support 71. Side groove rails 815 penetrate through both sides of the first support 51, the second support 61, and the third support 71. The moving bracket 811 is slidably arranged in the slot 814. A contact pressure roller 816 is rotatably arranged in the moving bracket 811. The bottom end of the clamping arm 813 is hinged in the side groove rail 815. One end of the connecting rod 812 is hinged to the clamping arm 813, and the other end of the connecting rod 812 is hinged to the bottom end of the moving bracket 811. A chute 8121 is formed on the top wall of the connecting rod 812, and a counterweight 8122 is slidably arranged in the chute 8121. An airbag 8131 is arranged on the clamping surface of the clamping arm 813. The pressure inflation fitting assembly 82 includes a first piston cylinder 821, a second piston cylinder 822, an electromagnet block 823, and a magnet 824. The first piston cylinder 821 and the second piston cylinder 822 are fixedly arranged on the support plate 2. The output end of the first piston cylinder 821 is fixedly connected to the moving bracket 811. An air pipe 825 is communicated between the bottom end of the first piston cylinder 821 and the airbag 8131. The electromagnet block 823 is fixedly installed on the bottom wall of the piston in the second piston cylinder 822, and the magnet 824 is fixedly installed on the inner bottom wall of the second piston cylinder 822. An air pipe 826 is communicated between the top end of the second piston cylinder 822 and the airbag 8131. An air pipe 827 is communicated between the bottom end of the first piston cylinder 821 and the bottom end of the second piston cylinder 822. A first solenoid valve 828 is installed on the air pipe 825, and a second solenoid valve 829 is installed on the air pipe 826. The second solenoid valve 829 is a time-delay solenoid valve, and the time-delay solenoid valve adopts a FESTO time-delay valve. The electromagnet block 823 is a commutation electromagnet. The pressure inflation fitting assembly 82 further includes a switch. One end of the electromagnet block 823 is connected to the switch, and the other end of the electromagnet block 823 is divided into two paths. One path is connected to one end of the first solenoid valve 828, and the other path is connected to one end of the second solenoid valve 829. The other ends of the first solenoid valve 828 and the second solenoid valve 829 both have normally open contacts. In the initial state, the first solenoid valve 828 is open, and the second solenoid valve 829 is closed. At this time, the electromagnet block 823 and the magnet 824 are in a mutually repulsive state. The contact pressure roller 816 is pressed down by the gravity of the aircraft radiator. The contact pressure roller 816 drives the moving bracket 811 to press down under the action of gravity. The moving bracket 811 drives the clamping arms 813 on both sides to tighten through the connecting rod 812, so as to clamp the aircraft radiator. While the moving bracket 811 moves downward, the gas in the first piston cylinder 821 is compressed, and the gas in the first piston cylinder 821 is transmitted to the airbag 8131 through the air pipe 825.It is transmitted into the piston cylinder two 822 through the air pipe three 827. The airbag 8131 has very strong deformability, so that the airbag 8131 fits adaptively on the outer sides of the three main parts of the aircraft radiator, ensuring the stable performance of clamping. When it is necessary to lift the aircraft radiator from this device, the knife of the switch closes with the normally open contact of the solenoid valve two 829. At this time, the solenoid valve one 828 closes, and the solenoid valve two 829 is delayed to open. The electromagnetic direction of the electromagnet block 823 changes. The electromagnet block 823 and the magnet 824 attract each other. The electromagnet block 823 will move a short distance to store energy under the attraction force. However, due to the solenoid valve two 829 that is delayed to open, the air pressures on the upper and lower sides of the electromagnet block 823 are basically unchanged. Therefore, the electromagnet block 823 is affected by the pressure in the piston cylinder two 822 and cannot move too much. When the solenoid valve two 829 opens, the electromagnet block 823 will move instantaneously. The electromagnet block 823 drives the piston in the piston cylinder two 822 to move downward, and the gas in the piston cylinder two 822 is transported back into the piston cylinder one 821 through the air pipe three 827, thus suddenly applying an air pressure to the piston cylinder one 821 and driving the moving bracket 811 to move upward. The upward movement of the moving bracket 811 drives the clamping arms 813 on both sides to unfold. And the gas in the airbag 8131 instantaneously enters the piston cylinder two 822 through the air pipe two 826, and the airbag 8131 becomes flat. The unlocking of the aircraft radiator will be faster and it is convenient to take out. Then the switch is turned back to the initial state. The solenoid valve one 828 opens, and the solenoid valve two 829 is delayed to close. The electromagnetic direction of the electromagnet block 823 returns to the initial state and repels the magnet 824. Due to the solenoid valve two 829 that has not been closed yet due to the delay, the electromagnet block 823 can move upward in the piston cylinder two 822 under the action of the repulsive force. At this time, the electromagnet block 823 drives the piston in the piston cylinder two 822 back to the original position. A small amount of gas in the piston cylinder one 821 enters the piston cylinder two 822. Because the piston in the piston cylinder two 822 moves upward, the gas in the upper part of the piston cylinder two 822 will be pressed into the airbag 8131. Then, because the piston in the piston cylinder one 821 also moves upward, part of the gas in the piston cylinder one 821 will enter the lower part of the piston cylinder two 822 through the air pipe three 827. In this way, the internal air pressure of the piston cylinder one 821 decreases, and the gas in the airbag 8131 will be sucked into the lower part of the piston cylinder one 821 through the air pipe one 825, ensuring that the airbag 8131 is not in an inflated state, so it does not affect the clamping effect on the aircraft radiator next time. Thus, the clamping arms 813, the airbag 8131, the piston cylinder one 821, and the piston cylinder two 822 all return to the original state.,

[0034] During specific use, the entire device is pushed to the position below the belly of the aircraft. Then, the scissor lift 3 is activated, and the scissor lift 3 drives the support plate 2 to rise. The support plate 2 drives the upper first support seat 51, second support seat 61, and third support seat 71 to rise to the position of the aircraft radiator. Subsequently, the aircraft radiator is detached, and the first support seat 51, second support seat 61, and third support seat 71 correspondingly support the aircraft radiator. By the gravity of the aircraft radiator, the contact roller 816 is pressed down. Under the action of gravity, the contact roller 816 drives the moving bracket 811 to press down. The moving bracket 811 drives the clamping arms 813 on both sides to tighten through the connecting rod 812, thereby clamping the aircraft radiator.

[0035] In the initial state, the first solenoid valve 828 is opened, and the second solenoid valve 829 is closed. At this time, the electromagnet block 823 and the magnet 824 are in a mutually repulsive state. By the gravity of the aircraft radiator, the contact roller 816 is pressed down. Under the action of gravity, the contact roller 816 drives the moving bracket 811 to press down. The moving bracket 811 drives the clamping arms 813 on both sides to tighten through the connecting rod 812, thereby clamping the aircraft radiator. While the moving bracket 811 moves downward, the gas in the first piston cylinder 821 is compressed. The gas in the first piston cylinder 821 is transmitted to the airbag 8131 through the first air pipe 825 and to the second piston cylinder 822 through the third air pipe 827. The airbag 8131 has very strong deformability, so that the airbag 8131 adaptively fits on the outer sides of the three main parts of the aircraft radiator, ensuring the stable performance of clamping.

[0036] After removing the bolts from the three main parts of the aircraft radiator, start the drive motor 417. The drive motor 417 drives the central gear 418 to rotate. The central gear 418 drives the first rack 411 and the second rack 412 to move in opposite directions. The first rack 411 and the second rack 412 drive the first moving platform 415 and the second moving platform 416 to slide respectively. Then, the first moving platform 415 drives the first support plate 5 to move through the first connecting shaft 4151, and the second moving platform 416 drives the third support plate 7 to move through the second connecting shaft 4161. The first support plate 5 and the third support plate 7 drive the first support seat 51 and the third support seat 71 to move away from the second support seat 61 in opposite directions. When the first gear 421 and the second gear 423 on the top wall driven by the first moving platform 415 and the second moving platform 416 move to the positions of the first side rack 422 and the second side rack 424 respectively, the first gear 421 and the second gear 423 rotate respectively under the action of the first side rack 422 and the second side rack 424. The first gear 421 drives the first support plate 5 to rotate through the first connecting shaft 4151, and the second gear 423 drives the third support plate 7 to rotate through the second connecting shaft 4161, thereby driving the first support seat 51 and the third support seat 71 to turn and extend respectively, separating the three main parts of the aircraft radiator stably clamped on the first support seat 51, the second support seat 61 and the third support seat 71, so as to perform maintenance operations on the three main parts of the aircraft radiator respectively;

[0037] When it is necessary to lift the aircraft radiator off the device, the blade of the switch closes with the normally open contact of the solenoid valve two 829. At this time, the solenoid valve one 828 closes, and the solenoid valve two 829 is delayed to open. The electromagnetic direction of the electromagnet block 823 changes. The electromagnet block 823 and the magnet 824 attract each other. The electromagnet block 823 will move a short distance to store energy under the attraction force. However, due to the solenoid valve two 829 with delayed opening, the air pressure on the upper and lower sides of the electromagnet block 823 is basically unchanged. Therefore, the electromagnet block 823 is affected by the pressure in the piston cylinder two 822 and cannot move too much. When the solenoid valve two 829 opens, the electromagnet block 823 will move instantaneously. The electromagnet block 823 drives the piston in the piston cylinder two 822 to move downward, and transports the gas in the piston cylinder two 822 back to the piston cylinder one 821 through the air pipe three 827, thereby suddenly applying an air pressure to the piston cylinder one 821 and driving the moving bracket 811 to move upward. The upward movement of the moving bracket 811 drives the clamping arms 813 on both sides to unfold, and the gas in the airbag 8131 instantaneously enters the piston cylinder two 822 through the air pipe two 826. The airbag 8131 becomes flat, and the unlocking of the aircraft radiator will be faster and easier to take out;

[0038] Then, turn the switch back to the initial state. Solenoid valve 1 828 opens, and solenoid valve 2 829 closes with a time delay. The electromagnetic direction of the electromagnet block 823 returns to the initial state and repels the magnet 824. Due to solenoid valve 2 829 that has not closed yet because of the time delay, the electromagnet block 823 can move upward in the piston cylinder 2 822 under the action of the repulsive force. At this time, the electromagnet block 823 drives the piston in the piston cylinder 2 822 back to the original position. A small amount of gas in the piston cylinder 1 821 enters the piston cylinder 2 822. Because the piston in the piston cylinder 2 822 moves upward, the gas in the upper part of the piston cylinder 2 822 will be pressed into the airbag 8131. Then, because the piston in the piston cylinder 1 821 also moves upward, part of the gas in the piston cylinder 1 821 will enter the lower part of the piston cylinder 2 822 through the air pipe 3 827. In this way, the internal air pressure of the piston cylinder 1 821 decreases, and the gas in the airbag 8131 will be sucked into the lower part of the piston cylinder 1 821 through the air pipe 1 825, ensuring that the airbag 8131 is not in an inflated state, so it does not affect the clamping effect on the aircraft radiator next time. Thus, the clamping arm 813, the airbag 8131, the piston cylinder 1 821, and the piston cylinder 2 822 all return to the original state.

[0039] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, creatively design a structural manner and an embodiment similar to this technical solution, they shall fall within the protection scope of the present invention.
