Description

Technical Field

[0001] The invention belongs to the technical field of locomotive maintenance, and in particular refers to a locomotive maintenance radiator disassembly and assembly lifting device. Background Art

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

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

The gravity of the aircraft radiator is used to compress the gas into an airbag. The airbag has strong deformability. The airbag realizes adaptive fitting clamping and fixation of the aircraft radiator to ensure stability during radiator maintenance. The aircraft radiator can be quickly unlocked by utilizing a unique electromagnetic control and air circuit linkage mechanism. Thanks to the delayed closing design of the solenoid valve, each component can automatically and orderly restore to its original position to prepare for the next clamping operation.

[0012] Compared with the prior art, the present invention adopts the above structure to achieve the following beneficial effects: 1. After the aircraft radiator is disassembled, it can be stably and accurately lifted to facilitate maintenance personnel to quickly and safely separate the three main parts of the aircraft radiator, and move 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 turn to one side, so as to perform maintenance operations on the three main parts of the aircraft radiator separately, without any obstruction between them; 2. The contact roller is pressed down by the gravity of the aircraft radiator. The contact roller drives the mobile bracket to be pressed down by the gravity. The mobile bracket drives the clamping arms on both sides to be tightened through the connecting rod, thereby clamping the aircraft radiator. The gas in the piston cylinder 1 is compressed by gravity. The gas in the piston cylinder 1 is transmitted to the airbag through the air pipe 1, and is transmitted to the piston cylinder 2 through the air pipe 3. The piston in the piston cylinder 2 is driven by the gas to move the electromagnetic block away from the magnet. The airbag has very strong deformability, so the airbag can be adaptively attached to the outer side surfaces 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, so that it has a wide range of applications and reduces the cost and management complexity of airlines that need to equip a variety of special maintenance tools for different aircraft models. 3. When the aircraft radiator needs to be lifted off, the unique electromagnetic control and air circuit linkage mechanism plays a key role. By switching the switch, the delayed effect of the second electromagnetic valve and the change of the magnetic pole direction of the electromagnetic block are used to realize the piston movement in the second piston cylinder and the switching of the air circuit flow direction. First, the force is accumulated for preparation, and then the air pressure is released instantly to push the mobile bracket upward, quickly unfold the clamping arm, and at the same time, the airbag is quickly exhausted and flattened. The whole unlocking process is fast and smooth, which greatly facilitates the maintenance personnel to remove the radiator from the device, and significantly improves the convenience and efficiency of maintenance operations; 4. After the radiator is removed, the switch is turned back to the initial state. Thanks to the delayed closing design of the solenoid valve 2, each component can automatically return to its original position in an orderly manner, the gas in the piston cylinder 1 and the piston cylinder 2 is rebalanced, and the clamping arm returns to the initial open state, ready for the next clamping operation. No complicated manual reset operation is required, which reduces the labor intensity of maintenance personnel and ensures the continuity and stability of the device's cyclic use; 5. Through auxiliary lifting and stable clamping, maintenance personnel do not need to use manpower to support and fix the aircraft radiator for a long time, which reduces the physical burden of maintenance personnel. Especially when handling heavy aircraft radiators or performing long-term maintenance operations, it can enable maintenance personnel to maintain a good working state and reduce safety accidents caused by fatigue operations. It also helps to improve the work enthusiasm and work efficiency of maintenance personnel; 6. In the process of lifting and separating the three parts of the radiator, the device can effectively prevent the aircraft radiator from colliding with surrounding objects due to improper operation or causing damage to the internal structure due to uneven force. Accurate lifting and stable clamping can ensure that the aircraft radiator remains in good condition before, during and after maintenance, thereby ensuring the quality of maintenance and reducing the increase in maintenance costs and potential flight safety hazards caused by secondary damage during the maintenance process.

A contact pressure roller 816 is rotatably arranged in the movable 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 movable bracket 811, a slide groove 8121 is provided on the top wall of the connecting rod 812, a counterweight block 8122 is slidably arranged in the slide groove 8121, and an airbag 8131 is arranged on the clamping surface of the clamping arm 813; the pressure inflation fitting component 82 includes a piston cylinder 1 821, a piston cylinder 2 822, an electromagnetic block 823 and a magnet 824, the piston cylinder 1 821 and the piston cylinder 2 822 are fixedly arranged on the support plate 2, the output end of the piston cylinder 1 821 is fixedly connected to the movable bracket 811, and the bottom end of the piston cylinder 1 821 is connected to the airbag 8 131 is connected with an air pipe 1 825, an electromagnetic block 823 is fixedly installed on the bottom wall of the piston in the piston cylinder 2 822, a magnet 824 is fixedly installed on the bottom wall of the piston cylinder 2 822, an air pipe 2 826 is connected between the top of the piston cylinder 2 822 and the airbag 8131, an air pipe 3 827 is connected between the bottom end of the piston cylinder 1 821 and the bottom end of the piston cylinder 2 822, an electromagnetic valve 1 828 is installed on the air pipe 1 825, and an electromagnetic valve 2 829 is installed on the air pipe 2 826. The electromagnetic valve 2 829 is a time-delay electromagnetic valve, and the time-delay electromagnetic valve adopts a FESTO time-delay valve. The electromagnetic block 823 is a reversing electromagnet. The pressure inflation fitting component 82 also includes a switch. One end of the electromagnetic block 823 is connected to the switch, and the other end of the electromagnetic block 823 is divided into two paths, one The first circuit is connected to one end of the electromagnetic valve 828, and the other circuit is connected to one end of the electromagnetic valve 829. The other ends of the electromagnetic valve 828 and the electromagnetic valve 829 are both normally open contacts. In the initial state, the electromagnetic valve 828 is opened and the electromagnetic valve 829 is closed. At this time, the electromagnetic block 823 and the magnet 824 are in a mutually repelling state. The contact roller 816 is pressed down by the gravity of the aircraft radiator. The contact roller 816 drives the movable bracket 811 to be pressed down under the action of gravity. The movable bracket 811 drives the clamping arms 813 on both sides to tighten through the connecting rod 812, thereby clamping the aircraft radiator. When the movable bracket 811 moves downward, the gas in the piston cylinder 821 is compressed, and the gas in the piston cylinder 821 is transmitted to the airbag 8131 through the air pipe 825.The force is transmitted to the piston cylinder 822 through the air pipe 827. The airbag 8131 has a very strong deformability, so that the airbag 8131 can adaptably fit the outer sides of the three main parts of the aircraft radiator to ensure the stability of the clamping performance. When the aircraft radiator needs to be lifted away from the device, the knife of the switch and the normally open contact of the solenoid valve 829 are closed. At this time, the solenoid valve 828 is closed, and the solenoid valve 829 is opened with a delay. The electromagnetic direction of the electromagnetic block 823 changes, and the electromagnetic block 823 and the magnet 824 attract each other. The electromagnetic block 823 is attracted and moves a short distance to store force, but due to the delayed opening of the solenoid valve 829, the electromagnetic The air pressure on the upper and lower sides of the magnetic block 823 is basically unchanged, so the electromagnetic block 823 is affected by the pressure in the piston cylinder 822, which makes it unable to move too much. When the electromagnetic valve 829 is opened, the electromagnetic block 823 will move instantly, and the electromagnetic block 823 drives the piston in the piston cylinder 822 to move downward, and transports the gas in the piston cylinder 822 back to the piston cylinder 1 821 through the air pipe 827, thereby suddenly giving the piston cylinder 1 821 an air pressure effect and driving the mobile bracket 811 to move upward. The upward movement of the mobile bracket 811 drives the clamping arms 813 on both sides to unfold, and the gas in the airbag 8131 is instantly released through the air pipe 826 Entering piston cylinder 2 822, airbag 8131 becomes flat, the aircraft radiator will be unlocked faster and easier to take out, and then the switch is turned back to the initial state, solenoid valve 1 828 is opened, solenoid valve 2 829 is closed with a delay, and the electromagnetic direction of electromagnetic block 823 returns to the initial state and repel each other with magnet 824. Since electromagnetic valve 2 829 has not been closed due to the delay, electromagnetic block 823 is affected by the repulsive force and can move upward in piston cylinder 2 822. At this time, electromagnetic block 823 drives the piston in piston cylinder 2 822 back to its original position, and a small amount of gas in piston cylinder 1 821 enters piston cylinder 2 822. Because the piston in piston cylinder 2 822 moves When the piston moves upward, the gas in the upper part of the piston cylinder 822 will be pressed into the airbag 8131. Then, as the piston in the piston cylinder 821 also moves upward, part of the gas in the piston cylinder 821 will enter the lower part of the piston cylinder 822 through the air pipe 827. In this way, the internal air pressure of the piston cylinder 821 is reduced, and the gas in the airbag 8131 will be sucked into the lower part of the piston cylinder 821 through the air pipe 825, ensuring that the airbag 8131 will not be in an expanded state, so as not to affect the clamping action on the aircraft radiator next time, so that the clamping arm 813, the airbag 8131, the piston cylinder 821 and the piston cylinder 822 all return to their original state.

[0020] When in use, the device is pushed as a whole to the lower position of the belly of the aircraft, and the scissor lift 3 is started. The scissor lift 3 drives the support plate 2 to rise, and the support plate 2 drives the first bracket 51, the second bracket 61 and the third bracket 71 above to rise to the aircraft radiator, and then the aircraft radiator is detached. The first bracket 51, the second bracket 61 and the third bracket 71 support the aircraft radiator accordingly, and the contact roller 816 is pressed downward by the gravity of the aircraft radiator. The contact roller 816 drives the movable bracket 811 to be pressed downward under the action of gravity, and the movable bracket 811 drives the clamping arms 813 on both sides to be tightened through the connecting rod 812, so as to clamp the aircraft radiator; In the initial state, the electromagnetic valve 1 828 is opened, and the electromagnetic valve 2 829 is closed. At this time, the electromagnetic block 823 and the magnet 824 are in a mutually repelling state. The contact roller 816 is pressed down by the gravity of the aircraft radiator. The contact roller 816 drives the movable bracket 811 to be pressed down under the action of gravity. The movable bracket 811 drives the clamping arms 813 on both sides to be tightened through the connecting rod 812, so as to clamp the aircraft radiator. When the movable bracket 811 moves downward, the gas in the piston cylinder 1 821 is compressed. The gas in the piston cylinder 1 821 is transmitted to the airbag 8131 through the air pipe 1 825, and is transmitted to the piston cylinder 2 822 through the air pipe 3 827. The airbag 8131 has very strong deformability, so that the airbag 8131 can be adaptively attached to the outer side surfaces of the three main parts of the aircraft radiator to ensure the stable clamping performance. 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 respectively drive the first moving platform 415 and the second moving platform 416 to slide, then the first moving platform 415 drives the first support plate 5 to move through the connecting shaft 1 4151, the second moving platform 416 drives the third support plate 7 to move through the connecting shaft 2 4161, the first support plate 5 and the third support plate 7 respectively drive the first bracket 51 and the third bracket 71 in opposite directions away from the second bracket 61, and the first moving platform 415 and the second moving platform 416 drive the first support plate 51 and the third bracket 71 to move away from the second bracket 61. When the first gear 421 and the second gear 423 of the top wall 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 under the action of the first side rack 422 and the second side rack 424 respectively, the first gear 421 drives the first support plate 5 to rotate through the connecting shaft 1 4151, and the second gear 423 drives the third support plate 7 to rotate through the connecting shaft 2 4161, thereby driving the first bracket 51 and the third bracket 71 to turn and extend respectively, and separating the three main parts of the aircraft radiator stably clamped on the first bracket 51, the second bracket 61 and the third bracket 71, so as to perform maintenance operations on the three main parts of the aircraft radiator respectively; When the aircraft radiator needs to be lifted off the device, the knife of the switch and the normally open contact of the electromagnetic valve 829 are closed. At this time, the electromagnetic valve 828 is closed, and the electromagnetic valve 829 is opened with a delay. The electromagnetic direction of the electromagnetic block 823 changes, and the electromagnetic block 823 and the magnet 824 attract each other. The electromagnetic block 823 moves a short distance to accumulate power due to the attraction. However, due to the delayed opening of the electromagnetic valve 829, the air pressure on the upper and lower sides of the electromagnetic block 823 remains basically unchanged. Therefore, the electromagnetic block 823 is affected by the pressure in the piston cylinder 822, which makes it unable to move too much. When the electromagnetic valve 829 is opened, the electromagnetic block 823 is opened with a delay. When it is turned on, the electromagnetic block 823 will move instantly, and the electromagnetic block 823 drives the piston in the second piston cylinder 822 to move downward, and the gas in the second piston cylinder 822 is transported back to the first piston cylinder 821 through the third air pipe 827, so that the first piston cylinder 821 is suddenly given an air pressure effect, and the mobile bracket 811 is driven to move upward. The upward movement of the mobile bracket 811 drives the clamping arms 813 on both sides to unfold, and the gas in the airbag 8131 instantly enters the second piston cylinder 822 through the second air pipe 826, and the airbag 8131 becomes flat, and the aircraft radiator is unlocked faster, which is convenient for removal; Then the switch is turned back to the initial state, solenoid valve 1 828 is opened, solenoid valve 2 829 is closed after a delay, and the electromagnetic direction of electromagnetic block 823 returns to the initial state and repels each other with magnet 824. Since electromagnetic valve 2 829 has not been closed after a delay, electromagnetic block 823 is repelled and can move upward in piston cylinder 2 822. At this time, electromagnetic block 823 drives the piston in piston cylinder 2 822 to return to its original position, and a small amount of gas in piston cylinder 1 821 enters piston cylinder 2 822. Because the piston in piston cylinder 2 822 moves upward, the gas in the upper part of piston cylinder 2 822 will The airbag 8131 is pressed in, and then since 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 is reduced, 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 will not be in an expanded state, thereby not affecting the clamping effect on the aircraft radiator next time, so that the clamping arm 813, the airbag 8131, the piston cylinder 1 821 and the piston cylinder 2 822 all return to their original states.
