Description

Technical Field

[0001] This utility model relates to the field of aircraft duct repair technology, specifically to a device for repairing and cleaning dents in metal composite ducts. Background Technology

[0002] Composite conduits account for about 50% of all conduit repairs on an aircraft. Among them, LF2M metal composite conduits are relatively soft and are easily damaged by impacts during disassembly, transportation, and paint removal, resulting in surface dents. Therefore, dents are a common problem with composite conduits during aircraft conduit repairs.

[0003] Indentations can reduce the internal flow area of ​​metal conduits, increase fluid resistance, and weaken the conduit's structural strength. Under cyclic loading, the material near the indentation may prematurely develop fatigue cracks, potentially leading to aircraft accidents. Therefore, the technical requirements for aircraft conduit repair stipulate that the depth of an indentation on the conduit surface cannot exceed 5% of the conduit's outer diameter. If this requirement cannot be met, the conduit must be scrapped and replaced as is.

[0004] Currently, the repair method for dents on the surface of metal composite ducts involves inserting a mandrel into the dented area within the duct's cavity and then using a hammer to tap the deformed area around the dent to repair it. However, in actual repair scenarios, dents are mostly located in the middle of the metal composite duct. Because the mandrel cannot bend, it cannot reach the damaged area, making repair impossible. This limits the repair of dents to the straight sections at both ends of the duct that the mandrel can support. For ducts with unrepairable dents, the entire duct needs to be replaced. Manufacturing and replacing a single metal composite duct requires 27 steps, significantly increasing the workload of aircraft repair, extending delivery cycles, and increasing production costs.

A ball bearing matching the inner diameter of the composite conduit is inserted into the first connecting end of the composite conduit and connected to the second input interface. When the hydraulic repair module of the control cabinet is activated, hydraulic oil enters the composite conduit through the output interface, connecting pipe, second input interface, and first connecting end, pushing the ball bearing to roll forward within the composite conduit. The hydraulic oil and the ball bearing eventually exit from the second connecting end, thus achieving the repair of the dents in the composite conduit.

[0009] As a further improvement of this utility model, the control cabinet is also provided with a gas purging module, which is used to realize the combined purging of the conduit after repair and cleaning.

[0013] As a further improvement of this utility model, the top of the cleaning cabinet is provided with a push-pullable cover to facilitate opening or closing the cleaning cabinet.

[0031] Example

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the device for repairing and cleaning dents in metal composite conduits according to this utility model includes a control cabinet 200 and a cleaning cabinet 300. The control cabinet 200 can be configured as a PLC control cabinet, containing multiple independently operating functional modules. The cleaning cabinet 300 has a rectangular cabinet structure. The composite conduit 100 to be repaired is placed inside the cleaning cabinet 300 to reduce the impact on the composite conduit 100 during the repair process. An output interface 210 is provided on one side of the control cabinet 200, and a second input interface 306 is provided on one side of the cleaning cabinet 300. The output interface 210 and the second input interface 306 are connected via a connecting pipe 500. The control cabinet 200 contains a hydraulic repair module, and the cleaning cabinet 300 contains a support frame 301. The composite conduit 100 to be cleaned is placed inside the cleaning cabinet 300, and the second connecting end 102 of the composite conduit 100 is fixed to the support frame 301. A ball bearing 600 matching the inner diameter of the composite conduit 100 is inserted into the first connecting end 101 of the composite conduit 100 and connected to the second input interface 306. When the hydraulic repair module of the control cabinet 200 is activated, hydraulic oil enters the combined conduit 100 through the output interface 210, connecting pipe 500, second input interface 306, and first connecting end 101, pushing the ball bearing 600 to roll forward within the combined conduit 100. The hydraulic oil and ball bearing 600 eventually exit from the second connecting end 102, thus repairing the dent in the combined conduit 100. Figure 2 As shown, a drain port 305 is also provided at the bottom of the cleaning cabinet 300, through which the hydraulic oil waste generated during the repair of the pressure pit is recycled.

[0033] In this embodiment, the control cabinet 200 and the cleaning cabinet 300 are connected by a connecting pipe 500. A hydraulic repair module is installed in the control cabinet 200, and a support frame 301 is installed in the cleaning cabinet 300. The combined conduit 100 to be cleaned is placed inside the cleaning cabinet 300, and the second connecting end 102 is fixed to the support frame 301. A ball bearing 600 is inserted into the first connecting end 101 and connected to the second input interface 306 of the cleaning cabinet 300, thus realizing the installation of the combined conduit 100. When the hydraulic repair module is activated, the hydraulic repair... The hydraulic oil output from the composite module enters the combined conduit 100 through the connecting pipe 500, and pushes the ball bearing 600 to roll rapidly forward in the combined conduit 100. The hydraulic oil and the ball bearing 600 finally rush out from the second connecting end 102. The rolling of the ball bearing 600 realizes the repair of the dents in the combined conduit 100. It can also easily repair multiple dents at various locations on the entire metal combined conduit, greatly reducing the probability of the metal combined conduit being scrapped and replaced due to the inability to repair the dents, thereby saving manpower, materials, time and other costs.

[0034] In this embodiment, the control cabinet 200 is also equipped with a cleaning module, such as... Figure 5 and Figure 6 As shown, the cleaning cabinet 300 is equipped with a cleaning connecting pipe 307, and a third input interface 308 connected to one end of the cleaning connecting pipe 307 is provided on the other side of the cleaning cabinet 300. When the combined conduit 100 needs to be cleaned, the connecting pipe 500 is connected to the third input interface 308, and the first connecting end 101 is connected to the other end of the cleaning connecting pipe 307. The cleaning module is then activated, and the cleaning fluid enters the combined conduit 100 through the output interface 210, connecting pipe 500, third input interface 308, cleaning connecting pipe 307, and first connecting end 101 to clean the combined conduit 100, and is discharged from the second connecting end 102. At the same time, the waste liquid generated during the cleaning of the conduit can be recovered through the drain port 305 at the bottom of the cleaning cabinet 300.

[0035] In this embodiment, the control cabinet 200 is also equipped with a gas purging module, which is used to purge the combined conduit 100 after repair and cleaning.

[0036] like Figure 2 and Figure 4As shown, the control panel of the control cabinet 200 is equipped with a high-pressure gauge 201, a low-pressure gauge 202, a hydraulic start button 203, a cleaning start button 204, a hydraulic stop button 205, a cleaning stop button 206, a high-pressure regulating valve 207, a low-pressure regulating valve 208, and a cold air switch valve 209. The high-pressure gauge 201, low-pressure gauge 202, hydraulic start button 203, hydraulic stop button 205, high-pressure regulating valve 207, and low-pressure regulating valve 208 are connected to the hydraulic repair module. The cleaning start button 204 and cleaning stop button 206 are connected to the cleaning module. The cold air switch valve 209 is connected to the gas purging module.

[0037] like Figure 4 As shown, a first input interface 211 is provided on the other side of the control cabinet 200, such as... Figure 7 As shown, the first input interface 210 can be connected to the cleaning agent storage cylinder 212, the compressed air source 213, and the hydraulic oil tank 214 respectively, so that when the corresponding functional module is started, the cleaning agent, compressed air, and hydraulic oil enter the control cabinet 200 and are output through the output interface 210. In the hydraulic repair module of the control cabinet 200, a two-position two-way solenoid valve 215 is also provided. The high-pressure regulating valve 207 and the low-pressure regulating valve 208 work together with the two-position two-way solenoid valve 215 to jointly regulate the pressure of the hydraulic oil during crater repair. Specifically, the high-pressure regulating valve 207 is a pilot-operated relief valve, and the low-pressure regulating valve 208 is a direct-acting relief valve. When the solenoid of the two-position two-way solenoid valve 215 is de-energized, the hydraulic system pressure is set by the pilot-operated relief valve. When the solenoid of the two-position two-way solenoid valve 215 is energized, the direct-acting relief valve is connected to the circuit. If the set pressure of the direct-acting relief valve is lower than the set pressure of the pilot-operated relief valve, the hydraulic system pressure is set by the direct-acting relief valve. If the set pressure of the direct-acting relief valve is higher than the set pressure of the relief valve, the hydraulic system pressure is set by the pilot-operated relief valve. That is, the low pressure is regulated by the low-pressure regulating valve 208. When the regulated pressure exceeds the pressure set by the low-pressure regulating valve 208, the low-pressure regulating valve 208 stops working, and the high-pressure regulating valve 207 regulates the hydraulic system pressure.

[0038] like Figure 5 As shown, the cleaning cabinet 300 is also equipped with a barrier net 302, the direction of which corresponds to the movement direction of the marble 600, in order to intercept the marble 600 that rushes out from the second connecting end 102. Correspondingly, an inclined collection trough 304 is also provided below the barrier net 302, and the collection trough 304 extends to the outside of the cleaning cabinet 300 to collect the marble 600.

[0039] like Figure 2 and Figure 5As shown, the top of the cleaning cabinet 300 is equipped with a sliding cover 303 to facilitate opening or closing the cleaning cabinet 300, preventing the ball bearing 600 from being ejected from the cleaning cabinet 300 during the dent repair process, and also preventing liquid from spraying out of the cleaning cabinet 300 during the dent repair cleaning process. Furthermore, the cover 303 can be a glass cover to facilitate real-time observation of the status of the combined conduit 100.

[0040] like Figure 2 As shown, both the control cabinet 200 and the cleaning cabinet 300 are equipped with casters 400 at the bottom for easy movement.

[0041] This embodiment also provides a method for cleaning and repairing cratering in metal composite conduits, which is implemented based on the aforementioned equipment for cleaning and repairing cratering in metal composite conduits, and includes the following steps:

[0042] Step S1: Place the combined conduit 100 to be cleaned into the cleaning cabinet 300. The second connecting end 102 of the combined conduit 100 is fixed to the support frame 301. Insert a ball bearing 600 matching the inner diameter of the combined conduit 100 into the first connecting end 101 of the combined conduit 100 and connect it to the second input interface 306. Then connect the control cabinet 200 to the cleaning cabinet 300 through the connecting pipe 500. Set the hydraulic oil pressure on the operation panel of the control cabinet 200. Further, the output pressure of the hydraulic oil is determined by the diameter and indentation depth of the combined conduit 100. The larger the diameter of the combined conduit 100 and the indentation depth less than or equal to 5% of the outer diameter of the combined conduit 100, the lower the adjusted pressure, and vice versa. In actual operation, first adjust to a smaller pressure. If the ball bearing 600 cannot pass through, gradually increase the output pressure to allow the ball bearing 600 to roll smoothly within the combined conduit 100.

[0043] Step S2: Press the hydraulic start button 203 to start the hydraulic repair module. Hydraulic oil enters the combined conduit 100 through the connecting pipe 500 and pushes the ball 600 to roll forward in the combined conduit 100 to repair the dents on the surface of the combined conduit 100. Press the hydraulic stop button 205 to turn off the hydraulic repair module.

[0044] Step S3: Open the air conditioning switch valve 209 and start the gas purging module. Use compressed gas to blow the residual hydraulic oil in the combined duct 100 to the cleaning cabinet 300 for recovery.

[0045] Step S4: After the hydraulic oil in the combined conduit 100 is purged, press the cleaning start button 204 to start the cleaning module to clean the combined conduit 100, and recycle the waste liquid generated during cleaning.

[0046] Step S5: After the combined duct 100 is cleaned, press the cleaning stop button 206 and open the air conditioning switch valve 209 to restart the gas purging module to purge and dry the combined duct 100. After completion, close the air conditioning switch valve 209.

[0047] Step S6: Remove the combined conduit 100 from the cleaning cabinet 300 and retrieve the ball 600. The conduit dent repair work is completed.

[0048] In this embodiment, the hydraulically driven ball bearing 600 rapidly rolls within the inner cavity of the combined conduit 100 to repair surface dents. This solves the problem of complex-shaped combined conduits 100 being unable to be repaired using a mandrel for support. Furthermore, multiple dents on the same combined conduit 100 can be repaired simultaneously by the ball bearing 600 rolling once, greatly improving work efficiency. At the same time, this embodiment allows for simultaneous dent repair and cleaning / drying of the combined conduit 100, eliminating the need for a separate cleaning and drying process after dent repair, thus saving operation time.

[0049] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
