Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of aero-engine test runs, and in particular, to an aero-engine test run system. Background Art
[0002] The full-engine test run of an aero-engine is an essential and important test step in the engine development process. Conducting the full-engine test is the only means to finally determine whether the various indicators of the engine meet the design requirements. To simulate the various performance indicators of the aero-engine in the installed state, corresponding intake systems and exhaust systems need to be set up in the test workshop. Since the large-power turboprop engine has a large air flow rate and a high flow velocity during the test, high noise is easily generated during the test. If the flow field in the test workshop is uneven, problems such as gas backflow are extremely likely to occur. Therefore, it is necessary to reasonably design and layout the structure of the test workshop to meet the test requirements of the large-power turboprop engine and subsequent transformation needs.
[0003] In this regard, Chinese invention patent CN116104336A provides a turboprop engine test workshop, which includes a test workshop and an exhaust workshop arranged in sequence along the air flow direction of the engine. The front end of the test workshop is provided with an intake muffler arranged horizontally, and the end of the exhaust workshop is provided with an exhaust muffler arranged horizontally. Although this structure can better meet the intake requirements and exhaust requirements of the aero-engine, since the intake direction and the exhaust direction are set in a straight line direction, the overall layout of the workshop is relatively long, occupying a large space and having high requirements for the site.

[0019] The following detailed description of embodiments of the present invention is provided in conjunction with the accompanying drawings. However, the present invention may be implemented in a variety of different ways as defined and covered below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The term "and / or" used herein includes all or any unit and all combinations of one or more associated listed items. The terms "first" and "second" etc. in the description and claims of the present invention are used to distinguish different objects, rather than to describe a specific order.
[0021] Figures 1 to 17 Collectively show the aviation engine test run system provided by an embodiment of the present invention, which is used for conducting ground tests on aviation engines to detect the performance, reliability, durability, etc. of the aviation engines, can meet the working conditions of the aviation engines and has a better noise reduction effect, and has a reasonable and compact overall layout, occupies a small space, and has strong applicability.
[0022] Please refer to Figure 1 and Figure 2 , the aviation engine test run system 1000 includes a test workshop 4, an intake silencing tower 5, a gas exhaust silencing tower 6, and a propeller flow exhaust silencing chamber 7. The test workshop 4 is used for testing the aviation engine. The intake silencing tower 5 is arranged at the front end of the test workshop 4 along the air flow direction of the aviation engine. The gas exhaust silencing tower 6 and the propeller flow exhaust silencing chamber 7 are sequentially arranged at the rear end of the test workshop 4 along the air flow direction of the aviation engine.
[0023] Furthermore, the intake silencing tower 5 extends vertically upward and its intake end is arranged vertically downward. The gas exhaust silencing tower 6 is arranged between the test workshop 4 and the propeller flow exhaust silencing chamber 7. The gas exhaust silencing tower 6 extends vertically upward and its exhaust end is arranged vertically upward. The exhaust end of the propeller flow exhaust silencing chamber 7 extends horizontally along the length direction of the test workshop 4. The intake silencing tower 5 is used to introduce air into the test workshop 4. The gas exhaust silencing tower 6 is used to discharge the gas generated by the aviation engine in the test workshop 4. The propeller flow exhaust silencing chamber 7 is used to discharge the propeller flow exhaust gas generated by the aviation engine in the test workshop 4. Multi-stage silencing structures and rectifying structures are provided in the intake silencing tower 5, the gas exhaust silencing tower 6, and the propeller flow exhaust silencing chamber 7.
[0024] In the aero-engine test run system 1000, the intake end of the intake silencing tower 5 intakes air downward in the vertical direction, the exhaust end of the gas exhaust silencing tower 6 exhausts gas upward in the vertical direction, and the exhaust end of the propeller flow exhaust silencing chamber 7 exhausts gas horizontally, realizing a structural layout of vertical intake and horizontal exhaust. While meeting the intake requirements and exhaust requirements of the aero-engine, the overall layout is more reasonable and compact, occupies less space, can adapt to different sites, has stronger applicability. Moreover, since the gas exhaust silencing tower 6 and the propeller flow exhaust silencing chamber 7 are independently arranged, the gas can be better exhausted, effectively avoiding the problem of gas backflow during the test, and improving the test safety and test effect. Secondly, since multi-stage sound absorption structures and rectification structures are provided in the intake silencing tower 5, the gas exhaust silencing tower 6 and the propeller flow exhaust silencing chamber 7, hierarchical sound absorption and rectification can be achieved, the exhaust effect is better, and the test noise can be prevented from spreading outward, ensuring the test safety.
[0025] As Figure 1 shown, the aero-engine test run system 1000 further includes an assembly workshop 3 and an auxiliary workshop 8 provided on one side of the test workshop 4. The assembly workshop 3 is used for assembling aero-engines. The assembly workshop 3 is provided at the intake end of the test workshop 4, and the auxiliary workshop 8 is provided at the exhaust end of the test workshop 4. The auxiliary workshop 8 has two floors in the height direction. The first-floor auxiliary workshop includes a lubricating oil storage room 81, an electrical equipment room 82, and a fuel room 83 arranged in sequence along the direction away from the assembly workshop 3. The second-floor auxiliary workshop includes a dressing and sound insulation room 84, a control room 85, and a data analysis room 86 arranged in sequence along the direction away from the assembly workshop 3. The control room 85 is provided directly above the electrical equipment room 82 and is used to control the electrical equipment in the electrical equipment room 82.
[0026] Specifically, the lubricating oil storage room 81 is used for storing lubricating oil, and the fuel oil room 83 is used for storing fuel oil. Arranging the lubricating oil storage room 81 near the engine installation position of the test workshop 4 is beneficial for subsequent lubricating oil filling, preparation of various test equipment, and connection of pipelines. Placing the fuel oil room 83 at a position far from the engine installation position of the test workshop 4 can enhance safety and prevent fuel from directly contacting high temperatures. Secondly, since the auxiliary workshop 8 has two floors in the height direction, the dressing and soundproofing room 84, control room 85, and data analysis room 86 that do not require large equipment are sequentially arranged on the second floor. This can not only efficiently utilize the longitudinal space, making the overall layout more reasonable and compact, but also facilitate the pipeline connection and installation between the control room 85 and the electrical equipment room 82, enabling the control room 85 to quickly control the electrical equipment in the electrical equipment room 82. Moreover, the dressing and soundproofing room 84 is used to soundproof and reduce noise for the control room 85 and data analysis room 86. While facilitating entry and exit for dressing in the control room 85 and data analysis room 86, it can effectively reduce the noise impact of the test process in the test workshop 4 on the control room 85 and data analysis room 86.
[0027] Preferably, the electrical equipment room 82 includes a process equipment room 821, an electrical room 822, and a loading cabinet room 823 arranged in sequence along the direction away from the assembly workshop 3. The process equipment room 821 is used for arranging the oil supply station, air system, and circulating cooling water system. The oil station specifically includes a lifting platform oil station, a hydraulic loading oil station, an oil seal oil station, etc. Since the process equipment room 821 is relatively close to the test workshop 4, it is convenient for the oil station, air system, and circulating cooling water system to be connected to the test workshop 4. Secondly, the electrical room 822 is used for arranging electrical control cabinets and power cabinets, and the loading cabinet room 823 is used for arranging electrical loading cabinets. The loading cabinets are independently set to reduce the impact of their heat dissipation operations on other electrical equipment, and the adjacent arrangement of the electrical room 822 and the loading cabinet room 823 facilitates unified management.
[0028] Furthermore, the electrical equipment room 82 further includes an accessory storage room 824 and an air compressor room 825 arranged in sequence at the rear end of the loading cabinet room 823 along the direction away from the assembly workshop 3. The accessory storage room 824 is used for storing accessories, and the air compressor room 825 is used for installing air compressors. Different equipment is separated by multiple workshops to avoid mutual influence.
[0029] Furthermore, the dressing and soundproofing room 84 includes a dressing room 841 and a soundproofing room 842 arranged in sequence along the direction away from the assembly workshop 3, achieving double sound insulation for the control room 85 through the dressing room 841 and the soundproofing room 842.
[0030] Further, the control room 85 includes an instrument room 851 and an operation room 852 arranged in sequence along the direction away from the assembly workshop 3. The instrument room 851 is used for arranging instruments and meters, and the operation room 852 is used for operating the instruments and meters. Separating the instrument room 851 and the operation room 852 can avoid the operation room 852 from being too messy, and at the same time, further sound insulation can be achieved for the operation room 852 through the instrument room 851.
[0031] Further, a washroom 87 is also provided on one side of the data analysis room 86 away from the control room 85 to facilitate the testers in the control room 85 and the data analysis room 86.
[0032] Please refer to Figure 3 and Figure 5 , on the wall between the electrical equipment room 82 and the test workshop 4, there is a pipeline installation module 91. The pipeline installation module 91 includes two fixing plates 911 for fitting the opposite sides of the wall, a plurality of pipeline channels 912 arranged between the two fixing plates 911, and sound insulation materials 913 filled on the outer periphery of the pipeline channels 912. The pipeline channels 912 are provided with connection ports for docking equipment pipelines on the fixing plates 911. Among them, at least some of the pipeline channels 912 have different diameters to meet different pipeline installations. By docking the equipment pipelines through the pipeline channels 912, while facilitating the transportation of substances such as lubricating oil, fuel oil, hydraulic oil, and coolant, a good sound insulation and noise reduction effect can also be achieved, and the noise in the test workshop 4 can be prevented from spreading outward along the pipeline installation position.
[0033] Please refer to Figure 4 and Figure 6 , on the wall between the control room 85 and the test workshop 4, there is a wire threading module 92. The wire threading module 92 includes a plugging plate 921 embedded in the wall, a plurality of wire threading holes 922 arranged on the plugging plate 921, and a sealing plug for detachably plugging the wire threading holes 922. At least some of the wire threading holes 922 have different diameters. Wiring personnel can take out the sealing plugs at the corresponding positions according to needs, and then pass the cables in the test workshop 4 through the corresponding wire threading holes 922 to the control room 85. This structure not only ensures the sealing of the test workshop 4, but also reduces the physical vibration of the cables during transmission, ensures the constant temperature and humidity environment of the control room 85, and thus increases the accuracy and precision of data transmission.
[0034] Preferably, a constant temperature and humidity system (not shown in the figure, the same below) for adjusting temperature and humidity is provided in both the control room 85 and the data analysis room 86. The temperature and humidity of the control room 85 and the data analysis room 86 are adjusted through the constant temperature and humidity system to ensure that relevant instruments and meters are maintained in a suitable working environment and avoid being affected by the high temperature in the test workshop 4.
[0035] Please refer to Figures 7 to 12 , the aero-engine test system 1000 further includes a suspended rail soundproof door 1. The rail-mounted soundproof door 1 is provided between the test workshop 4 and the assembly workshop 3. Through structural optimization, it can achieve a larger opening and closing area and has a good soundproof effect, meeting the requirements for the entry and exit of large equipment and test sound insulation. It can be applied to the aero-engine test system to achieve sound insulation and noise reduction between the assembly workshop 3 and the test workshop 4.
[0036] Please refer to Figure 7 and Figure 8 , the suspended rail soundproof door 1 includes a wall body 11, a suspended rail 12, a soundproof door leaf 13, and a translation mechanism (not shown in the figure, the same below). A door opening 111 adapted to the soundproof door leaf 13 is opened on the wall body 11. The suspended rail 12 is installed on the wall body 11. The suspended rail 12 is located above the door opening 111 and extends horizontally to one side of the door opening 111. The soundproof door leaf 13 is slidably installed on the suspended rail 12. The translation mechanism is connected to the soundproof door leaf 13 and is used to drive the soundproof door leaf 13 to slide open and close along the suspended rail 12. Further, the translation mechanism may specifically include a translation motor provided on the wall body 11 and a driving wheel connected to the output shaft of the translation motor. The driving wheel abuts against the soundproof door leaf 13 to drive the rolling movement of the driving wheel through the translation motor to drive the soundproof door leaf 13 to translate. In other embodiments, the driving wheel may also be set as a gear, and a rack meshing with the gear is provided on the soundproof door leaf 13. The translation of the rack is driven by driving the gear to rotate through the translation motor, and a more precise translation driving action can be achieved.
[0037] As Figure 9As shown, a sealing flange 112 is provided on the side of the wall 11 facing the soundproof door leaf 13. The sealing flange 112 is provided above the door opening 111 and extends in the direction towards the soundproof door leaf 13. A first sealing mechanism 14 is provided on the top surface of the sealing flange 112. The soundproof door leaf 13 includes a door leaf main body 131 and a sealing strip 132. The first end of the sealing strip 132 is fixedly connected to the door leaf main body 131 in the horizontal direction. The second end of the sealing strip 132 is inserted vertically into the first sealing mechanism 14. The middle position of the sealing strip 132 is provided with an arc-shaped structure or a right-angle structure so that its first end and second end are arranged in different directions. The first sealing mechanism 14 is used to clamp the sealing strip 132 after the soundproof door leaf 13 is closed, thereby sealing the gap between the soundproof door leaf 13 and the wall 11. The first sealing mechanism 14 is also used to loosen the sealing strip 132 when the soundproof door leaf 13 moves, so as not to affect the opening and closing movement of the soundproof door leaf 13.
[0038] Specifically, the suspended-rail soundproof door 1 adopts a sliding door structure and is driven to open and close by the translation mechanism, avoiding the situation that the soundproof door is too large in volume and too heavy to be manually opened and closed. Thus, it can meet the sealing requirements of large-sized door openings and adapt to the scenario of large-volume equipment entering and exiting. Moreover, with a suspended-rail design, compared with the ground-rail structure, it can avoid the problems that the ground is uneven and there are protrusions, which are not conducive to the entry and exit of large equipment. More importantly, a first sealing mechanism 14 is provided on the wall 11, which can clamp the sealing strip 132 on the soundproof door leaf 13 after the soundproof door leaf 13 is closed, thereby sealing the gap between the soundproof door leaf 13 and the wall 11, effectively solving the problem of poor sealing effect of conventional sliding doors, increasing the area of the door opening 11 while ensuring the sound insulation and noise reduction effect, and being able to meet the transportation requirements and noise reduction requirements of large aero-engine tests at the same time.
[0039] Please combine Figure 10 As shown, the first sealing mechanism 14 includes two first soundproof air cushions 141, a return spring 142 elastically pressed between the two first soundproof air cushions 141, and an electromagnet 143 provided on the first soundproof air cushion 141. Specifically, the two first soundproof air cushions 141 are respectively arranged on the opposite sides of the second end of the sealing strip 132, that is, the second end of the sealing strip 132 is inserted vertically between the two first soundproof air cushions 141. The return spring 142 is used to push the two first soundproof air cushions 141 apart to a preset spacing state to loosen the sealing strip 132. The electromagnet 143 is used to attract the two first soundproof air cushions 141 in the energized state to drive the two first soundproof air cushions 141 to clamp the sealing strip 132.
[0040] The working principle of the first sealing mechanism 14 is as follows: when the electromagnet 142 is in a power-off state, it has no magnetic force. At this time, the elastic force of the reset spring 142 can push the two first sound-absorbing air cushions 141 apart to a preset spacing state, so that the first sound-absorbing air cushions 141 are separated from the sealing strip 132, enabling the sound-absorbing door leaf 13 to open and close smoothly; when the electromagnet 142 is in a powered-on state, the magnetic force generated by the electromagnet 142 can overcome the elastic force of the reset spring 142 and suck the two first sound-absorbing air cushions 141 together, so as to clamp the sealing strip 132 through the two first sound-absorbing air cushions 141, realizing efficient sealing of the gap between the sound-absorbing door leaf 13 and the wall 11. The sealing structure is simple and efficient, and the air cushion structure is used for sealing, which can ensure that the first sound-absorbing air cushion 141 closely adheres to the sealing strip 132, and the air cavity in the first sound-absorbing air cushion 141 can be used for sound absorption, effectively improving the sound absorption effect.
[0041] Preferably, the first sealing mechanism 14 further includes a mounting seat 144 disposed between the two first sound-absorbing air cushions 141, and two limiting components 145 respectively disposed at both ends of the mounting seat 144. The limiting component 145 includes a limiting block 1451 and a transmission rod 1452 connected to the limiting block 1451. The end of the transmission rod 1452 away from the limiting block 1451 passes through a preset limiting hole on the mounting seat 144 and is connected to the first sound-absorbing air cushion 141, and the transmission rods 1452 of the two limiting components 145 are connected to the two first sound-absorbing air cushions 141 in a one-to-one correspondence. The reset spring 142 abuts against the side of the limiting block 1451 away from the transmission rod 1452. The limiting block 1451 is used to move to a state of abutting against the inner wall of the mounting seat 144 under the elastic force of the reset spring 142 and limit the maximum moving stroke of the first sound-absorbing air cushion 141.
[0042] The limiting component 145 limits the maximum moving stroke of the first sound-absorbing air cushion 141 through the cooperation of the limiting block 1451 and the mounting seat 144 to prevent the first sound-absorbing air cushion 141 from loosening. The cooperation of the limiting block 1451 and the preset limiting hole on the mounting seat 144 can also be used to guide the moving direction of the first sound-absorbing air cushion 141, effectively improving the stability of the first sound-absorbing air cushion 141 and preventing the first sound-absorbing air cushion 141 from deflecting and affecting the clamping and sealing effect.
[0043] Preferably, the first sound-absorbing air cushion 141 is provided with the electromagnets 143 on both the upper and lower sides of the return spring 142, so as to simultaneously attract the first sound-absorbing air cushion 141 by the electromagnets 143 on both sides, ensure that the first sound-absorbing air cushion 141 is uniformly stressed, and be able to achieve a stable translational movement. In this embodiment, the electromagnets 143 are provided at corresponding positions on the two first sound-absorbing air cushions 141 to enhance the magnetic attraction effect and ensure the sealing strength; in other embodiments, the electromagnet 143 may also be provided only on one of the first sound-absorbing air cushions 141, and a metal part for the electromagnet 143 to magnetically attract is provided on the other first sound-absorbing air cushion 141, and the two first sound-absorbing air cushions 141 can also be controlled to be attracted by the electromagnet 143.
[0044] As Figure 11 shown, the suspended-rail sound-absorbing door 1 further includes a second sealing mechanism 15 provided at the bottom of the sound-absorbing door leaf 13. The second sealing mechanism 15 includes a second sound-absorbing air cushion 151 and a lifting assembly 152. The second sound-absorbing air cushion 151 is slidably connected to the bottom of the sound-absorbing door leaf 13 in the vertical direction, and the lifting assembly 152 is connected to the second sound-absorbing air cushion 151 and is used to drive the second sound-absorbing air cushion 151 to move up and down, so as to control the second sound-absorbing air cushion 151 to move up and down to a state of abutting against the ground or separating from the ground.
[0045] Specifically, after the sound-absorbing door leaf 13 is closed, the lifting assembly 152 can be used to drive the second sound-absorbing air cushion 151 to move downward to a state of tightly abutting against the ground, so as to seal the bottom gap of the sound-absorbing door leaf 13. Sealing through the air cushion structure can ensure that the second sound-absorbing air cushion 151 closely adheres to the ground, and the air cavity in the second sound-absorbing air cushion 151 can also be used for sound absorption, effectively improving the sound absorption effect at the bottom position, and further improving the sound insulation and noise reduction effect of the suspended-rail sound-absorbing door 1.
[0046] Preferably, the lifting assembly 152 includes a motor 1521 provided on the wall 11, a first crank 1522 connected to the output shaft of the motor 1521, a second crank 1523 rotatably provided on the sound-absorbing door leaf 13 in the horizontal direction, a screw rod 1524 rotatably installed in the sound-absorbing door leaf 13 in the vertical direction, a universal joint 1525 provided between the second crank 1523 and the screw rod 1524 and used to transmit the rotational power of the second crank 1523 to the screw rod 1524, and a lifting transmission member 1526 connected to the second sound-absorbing air cushion 151. The lifting transmission member 1526 is provided with a threaded hole threadedly connected to the screw rod 1524. The first crank 1522 is used to abut against the second crank 1523 after the sound-absorbing door leaf 13 is closed and transmit the rotational power of the motor 1521 to the second crank 1523.
[0047] Specifically, the first crank 1522 and the second crank 1523 are both provided with overlapping portions at a preset angle. When the soundproof door leaf 13 is in the open state, the second crank 1523 moves with the soundproof door leaf 13 to a state of separating from the first crank 1522; when the soundproof door leaf 13 is in the closed state, the second crank 1523 moves with the soundproof door leaf 13 to the working position of the first crank 1522. At this time, by driving the first crank 1522 to rotate through the motor 1521, the overlapping portion on the first crank 1522 can be rotated to the state of overlapping the second crank 1523 and drive the second crank 1523 to rotate. Thus, through the cooperation of the second crank 1523 and the universal joint 1525, reverse transmission is realized and the screw 1524 is driven to rotate. Furthermore, the lifting transmission member 1526 is driven to lift and move through thread cooperation, and the second soundproof air cushion 151 is driven to lift and move by the lifting transmission member 1526. Since the motor 1521 is arranged separately from the soundproof door leaf 13, the load of the soundproof door leaf 13 can be reduced, the opening and installation structure on the soundproof door leaf 13 can be reduced, and the smooth movement and soundproof effect of the soundproof door leaf 13 can be ensured.
[0048] Furthermore, there are two second soundproof air cushions 151, and the two second soundproof air cushions 151 are respectively arranged on the opposite sides of the soundproof door leaf 13. The two ends of the lifting transmission member 1526 respectively penetrate through the opposite sides of the soundproof door leaf 13 and are correspondingly connected to the two second soundproof air cushions 151 one by one. And the second soundproof air cushion 151 extends upward to cover the through holes of the lifting transmission member 1526 on the soundproof door leaf 13. By synchronously driving the two second soundproof air cushions 151 to lift and move through the lifting transmission member 1526, the two second soundproof air cushions 151 can jointly clamp the soundproof door leaf 13 to achieve a double-layer sealing effect, and the openings on the soundproof door leaf 13 can also be covered by the second soundproof air cushion 151 to ensure the soundproof effect.
[0049] Furthermore, the lifting assembly 152 further includes a mounting bracket 1527 arranged in the inner cavity of the soundproof door leaf 13. The mounting bracket 1527 is arranged above the screw 1524, and the screw 1524 is rotatably installed on the mounting bracket 1527. The mounting bracket 1527 limits the installation of the screw 1524 to improve the stability of the screw 1524.
[0050] Please combine Figure 7 and Figure 12, there are two walls 11. The two walls 11 are arranged at intervals and enclose to form a sound insulation cavity 113. The door openings 111 and the hanging rails 12 are provided on both walls 11. There are two sound insulation door leaves 13. The two sound insulation door leaves 13 are respectively arranged on the hanging rails 12 of the two walls 11. When the two sound insulation door leaves 13 are closed, they are used to block the door openings 111 on the two walls 11 at the same time and seal the sound insulation cavity. The hanging rail type sound insulation door 1 forms a cavity structure through two walls 11 arranged at intervals. After the two sound insulation door leaves 13 are closed at the same time, the sound insulation cavity 113 can be in a completely sealed state, effectively improving the sound insulation effect. After testing, the 160dB noise generated in the test workshop of the aero-engine test system can be reduced to 70dB.
[0051] Preferably, the door leaf main body 131 sequentially includes a first sound insulation board, a damping layer, a steel frame, sound insulation cotton, a composite sound insulation module and a second sound insulation board from the outside to the inside. By sequentially arranging multiple sound insulation structures, the noise can be greatly reduced, and the multiple sound insulation structures are supported by the steel frame, which can ensure the structural strength of the door leaf main body 131 and avoid deformation affecting the sealing effect.
[0052] Preferably, an infrared detection component (not shown in the figure, the same below) and / or a pressure detection component 16 are provided on the sound insulation door leaf 13. The infrared detection component includes an infrared sensor, which is used to detect whether there are obstacles in the closing direction of the sound insulation door leaf 13 through infrared signals. The pressure detection component 16 includes a safety airbag 161 and a pressure sensor arranged in the safety airbag 161. The safety airbag 161 is arranged on the side wall of the sound insulation door leaf 13, and the pressure sensor is used to detect the air pressure change of the safety airbag 161 to judge whether the safety airbag 161 touches an obstacle.
[0053] In this embodiment, both the infrared detection component and the pressure detection component 16 are provided on the sound insulation door leaf 13. By double anti-collision detection, it is judged whether there are obstacles in the closing direction of the sound insulation door leaf 13, effectively improving the safety.
[0054] Furthermore, a limiting wheel 121 is provided on the hanging rail 12. The limiting wheel 121 is used to abut against the sound insulation door leaf 13 and limit the opening and closing movement stroke of the sound insulation door leaf 13 to ensure the high-precision opening and closing of the sound insulation door leaf 13.
[0055] Please combine Figures 13 to 17, the aero-engine test run system 1000 further includes a hoisting device 2, which is used to achieve the rapid transfer of the aero-engine between the pre-assembly station in the assembly workshop 3 and the test station in the test workshop 4, and can realize the parallel operation of multiple pre-assembly stations, effectively improving the transfer efficiency and test efficiency of the aero-engine, reducing manual operation, and enhancing safety.
[0056] Please refer to Figure 13 and Figure 14 , the hoisting device 2 includes a crane 21, two parallel mounting tracks 22 for being mounted on the roof of the assembly workshop 3, a transfer track 23 spanning between the two parallel mounting tracks 22, and a pre-assembly track 24 and a transport track 25 provided on one side of the parallel mounting track 23 away from the other parallel mounting track 23. The pre-assembly track 24 is used to be arranged above the pre-assembly station, and the transport track 25 is used to extend to the roof of the test workshop 4. A moving mechanism (not shown in the figure, the same below) is provided on the transfer track 23, and the moving mechanism is used to drive the transfer track 23 to move along the length direction of the parallel mounting track 22 to a state of docking with the pre-assembly track 24 or docking with the transport track 25. The crane 21 is used to hoist the aero-engine on the pre-assembly station and drive the aero-engine to move along the pre-assembly track 24, the transfer track 23 and the transport track 25.
[0057] Specifically, the hoisting device 2 spans and installs the transfer track 23 through the two parallel mounting tracks 22, and the pre-assembly track 24 and the transport track 25 are provided on the outer side (the side away from the transfer track 23) of the parallel mounting tracks 22. While realizing the stable installation of the transfer track 23, the transfer track 23 can move along the parallel mounting track 22 with high precision to a state of docking with any pre-assembly track 24 or docking with the transport track 25, so that the crane 21 can move into different pre-assembly tracks 24 to hoist the aero-engine on the corresponding pre-assembly station, and can also move from different pre-assembly tracks 24 to the transfer track 23 and move along the transfer track 23 to the transport track 25, facilitating the crane 21 to directly lift the aero-engines on different pre-assembly stations in the assembly workshop 3 to the test stations in the test workshop 4, reducing the use of transfer vehicles, thereby reducing the clamping and positioning processes between the transfer vehicle and the pre-assembly station and between the transfer vehicle and the crane. Only through one hoisting operation can it be directly transferred from the pre-assembly station to the test station to achieve rapid replacement and transportation. Secondly, multiple pre-assembly stations can be operated in parallel by arranging multiple pre-assembly tracks 24 on the outer side of the parallel mounting tracks 22, enabling the assembly and lifting preparation work of multiple aero-engines to be carried out simultaneously, effectively improving the transport efficiency and facilitating the batch testing of multiple aero-engines.
[0058] Furthermore, the moving mechanism includes a first roller provided on both ends of the transfer rail 23, a first moving motor connected to the first roller and used to drive the first roller to roll, the first roller is embedded in a first roller groove preset in the assembling rail 22, and the first moving motor drives the first roller to roll along the first roller groove, thereby driving the transfer rail 23 to move along the assembling rail 22.
[0059] Please combine Figure 14 and Figure 15 The transport track 25 is provided with a gap 251 at the position of the muffler door 1 between the assembly workshop 3 and the test workshop 4. The hoisting device 2 further includes a turning track 26 rotatably provided at the gap 251. The turning track 26 is used to rotate to a state aligned with the transport track 25 to fill the gap 251 (at Figure 15 As shown in FIG), the direction-changing track 26 is also used to rotate to a state where it is staggered from the transport track 25 to form an escape space for closing the muffler door 1 at the gap 251 (in FIG). Figure 14 shown in ).
[0060] Specifically, the changing track 26 is arranged to rotate along a horizontal plane, and a changing motor (not shown in the figure, the same below) is provided on the changing track 26 for driving the changing track 26 to rotate. When the changing track 26 is driven by the changing motor to rotate to a state aligned with the transport track 25, the gap 251 can be filled, so that the crane 21 can move along the transport track 25 between the assembly workshop 3 and the test workshop 4; and when the test workshop 4 is conducting a test, the changing track 26 can be driven by the changing motor to rotate to a state offset from the transport track 25, and an escape space for the silencing door 1 to close can be formed at the gap 251, so that the silencing door 1 can be smoothly closed and seal the test workshop 4, which is conducive to achieving the sound insulation and noise reduction effect of the test workshop 4.
[0061] Preferably, the transport track 25 is provided on both parallel installation tracks 22, and the transport tracks 25 on the two parallel installation tracks 22 are used to extend to different test workshops 4. In other words, the hoisting device 2 can flexibly transport aircraft engines from multiple pre-installation stations to different test workshops 4, enabling parallel operation of at least two test workshops 4 and further improving testing efficiency.
[0062] like Figure 16As shown, the transport rails 25 on the two parallel rails 22 are arranged opposite each other, and the two ends of the transfer rail 23 are used to simultaneously connect with the transport rails 25 on the two parallel rails 22. Since the transport rails 25 on the two parallel rails 22 are arranged opposite each other, only one positioning position is required to simultaneously connect the transfer rail 23 with the two transport rails 25, thereby reducing the number of docking positioning structures on the transfer rail 23, simplifying the hoisting device 2, and making the overall structure simpler and more efficient.
[0063] Preferably, multiple pre-installation rails 24 are provided at intervals along the length of each of the two parallel installation rails 22. The multiple pre-installation rails 24 are used to be provided above multiple pre-installation stations in a one-to-one correspondence. By providing multiple pre-installation rails 24 on each of the two parallel installation rails 22, it is convenient to arrange more pre-installation stations and meet the transportation needs of more pre-installation stations. It should be understood that each pre-installation station can be used to assemble an aircraft engine separately, or different assembly processes of an aircraft engine can be carried out separately through multiple pre-installation stations. The hoisting device 2 can realize the flexible movement of the crane 21 between multiple pre-installation stations, meeting different usage needs and having strong applicability.
[0064] like Figure 14 As shown, the pre-installed rails 24 on the two parallel rails 22 are arranged in a one-to-one correspondence, and the ends of the transition rail 23 are used to simultaneously connect with the pre-installed rails 24 on the two parallel rails 22. Similarly, because the pre-installed rails 24 on the two parallel rails 22 are arranged opposite each other, only one positioning position is required to allow the transition rail 23 to simultaneously connect with the two pre-installed rails 24, thereby reducing the number of docking and positioning structures on the transition rails 23, simplifying the hoisting device 2, and making the overall structure simpler and more efficient.
[0065] Preferably, a rail locking mechanism (not shown, the same below) is provided at the end of the transfer rail 23. The rail locking mechanism is used to lock and secure the transfer rail 23 relative to the pre-installed rail 24 or to lock and secure the transfer rail 23 relative to the transport rail 25. The rail locking mechanism positions and secures the transfer rail 23, ensuring that the transfer rail 23 is stably docked with the pre-installed rail 24 or the transport rail 25, thereby enabling the crane 21 to move smoothly between the transfer rail 23 and the pre-installed rail 24 or between the transfer rail 23 and the transport rail 25.
[0066] Further, the track locking mechanism includes a telescopic assembly and a track locking pin connected to the telescopic assembly. The telescopic assembly may specifically adopt a pneumatic rod and a hydraulic rod, or include a motor and a linear transmission component connected to the output shaft of the motor. The telescopic assembly is connected to the track locking pin and is used to drive the track locking pin to telescopically move, so that the track locking pin extends and inserts into a preset positioning hole on the pre-installed track 24 or the transportation track 25, realizing the locking and fixing of the transfer track 23.
[0067] As Figure 17 shown, the crane 21 includes two lifting assemblies 211 arranged side by side. The lifting assembly 211 includes a drum 2111, a steel wire rope 2112, a pulley 2113, and a hook 2114 connected in sequence. There are two steel wire ropes 2112. The two steel wire ropes 2112 are arranged at intervals along the axial direction of the pulley 2113 and are both wound around the outer periphery of the pulley 2113. The drum 2111 is connected to the steel wire rope 2112 and is used to drive the steel wire rope 2112 to wind or unwind, thereby driving the pulley 2113 and the hook 2114 to move up and down.
[0068] Since the lifting assembly 211 includes two steel wire ropes 2112 arranged at intervals along the axial direction of the pulley 2113, and the steel wire ropes 2112 are wound around the outer periphery of the pulley 2113, so that the two ends of the steel wire rope 2112 are respectively arranged on opposite sides of the pulley 2113, thus the two steel wire ropes 2112 together form four pulling points, and the steel wire rope 2112 is arranged around the hook 2114, effectively ensuring the stability of the hook 2114 in three-dimensional directions, and being able to prevent the hook 2114 from tilting in any direction. Compared with the conventional hook structure, it can effectively ensure the stable transportation of the lifted object and prevent swinging during the lifting process. Secondly, since the crane 21 includes two lifting assemblies 211 arranged side by side, the two sides of the aeroengine are respectively lifted by the hooks 2114 on the two lifting assemblies 211. Thus, the position of the aeroengine can be flexibly adjusted by separately controlling the lifting height of any one of the hooks 2114, ensuring that the aeroengine is in a horizontal state during lifting and further improving the lifting stability.
[0069] Preferably, the cross-sections of the pre-installed track 24, the transfer track 23, and the transportation track 25 are all set to an "I"-shaped structure. The drum 2111 is provided with a double-hook driving assembly, and the double-hook driving assembly is used to clamp the opposite sides of the "I"-shaped structure and is used to move along the pre-installed track 24, the transfer track 23, and the transportation track 25.
[0070] Specifically, the pre-installed track 24, the transfer track 23, and the transportation track 25 are all made of I-beams, with a simple and efficient structure. The double-hook drive assembly includes two inverted "L"-shaped hooks arranged oppositely. By respectively clamping the two defined sides of the I-beam with the two inverted "L"-shaped hooks, multi-directional limiting of the crane 21 can be achieved, improving stability.
[0071] Furthermore, a second roller and a second moving motor connected to the second roller are provided at the bottom of the inverted "L"-shaped hook. The second roller abuts against the upper surface of the flange of the I-beam. By driving the second roller to roll along the I-beam through the second moving motor, the crane 21 can be driven to move along the pre-installed track 24, the transfer track 23, and the transportation track 25.
[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
