Detailed Implementation

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0046] With the rapid development of urban transportation in my country, high-speed trains have become a major mode of transportation. Currently, most high-speed trains operating in China use hollow axles, which not only helps to reduce axle weight, improve mechanical properties, and enhance the stability and safety of train operation, but also facilitates the detection of fatigue defects in axles.

[0047] Currently, during the axle flaw detection process at the EMU depot, a vehicle adapter needs to be fabricated to connect the flaw detection feed mechanism with the actual axle to be inspected. To improve the flaw detection progress, multiple adapters need to be fabricated for each axle diameter to ensure continuous operation of the flaw detection feed mechanism.

[0048] However, each aperture model requires the installation of multiple adapters in the early stages, which increases labor costs. Furthermore, equipping multiple adapters increases the user's procurement costs and occupies storage space. In addition, the adapters are complex in structure, large in size, heavy, and inconvenient for users to operate.

[0049] For this reason, see Figure 1 and Figure 5 This application provides a novel adapter 100 for a hollow axle flaw detection device. Figure 1 This is a schematic diagram of the hollow axle flaw detection equipment adapter 100 in the first embodiment of this application. Figure 5 This is a schematic diagram of the hollow axle flaw detection equipment adapter 100 in the second embodiment of this application. The hollow axle flaw detection equipment adapter 100 is used in a hollow axle flaw detection feed device (not shown).

[0050] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the hollow axle flaw detection equipment adapter 100 is located at one end of the flaw detection feed structure 200 in the hollow axle flaw detection feed device. Figure 2 for Figure 1 The diagram shown illustrates the installation of the hollow axle flaw detection equipment adapter 100 onto the flaw detection feed structure 200. Figure 6 for Figure 5 The diagram shows the hollow axle flaw detection equipment adapter 100 installed on the flaw detection feed structure 200.

[0051] The hollow axle flaw detection device adapter 100 is disposed at one end of the flaw detection feed structure 200 facing the wheelset to be tested (not shown), and the hollow axle flaw detection device adapter 100 can be connected to the axle end 310 of the hollow axle 300 of the wheelset to be tested. The hollow axle flaw detection feed device performs flaw detection on the hollow axle 300 of the wheelset to be tested through the flaw detection feed structure 200.

[0052] The wheelsets under test here are typically those of railway trains (locomotives) such as bullet trains or high-speed trains. Typically, the wheelset under test includes a hollow axle 300 and two wheel discs (not shown). The two wheel discs are symmetrically arranged on the two hollow axles 300. Both ends of the hollow axles 300 extend axially through the wheel discs. The hollow axles 300 are connected to the locomotive, and can drive the wheelset under test to rotate when the locomotive moves.

[0053] The flaw detection feed structure 200 of this application is mainly used for flaw detection of the hollow axle 300 of the wheelset under test. Furthermore, the hollow axle 300 is typically a hollow shaft. When flaw detecting the hollow axle 300, the flaw detection feed structure 200 can engage with the hollow axle 300 and extend into the inner cavity of the hollow axle 300, thereby achieving flaw detection on the hollow axle 300 and ensuring the accuracy of the flaw detection.

[0054] Furthermore, one end of the hollow axle 300 is a shaft end 310, and one end of the hollow axle flaw detection equipment adapter 100 is connected to the shaft end 310 of the hollow axle 300. This allows the flaw detection feed structure 200 to extend into the inner cavity of the hollow axle 300 via the shaft end 310 through the hollow axle flaw detection equipment adapter 100 to perform flaw detection on the hollow axle 300. After flaw detection is completed, the hollow axle flaw detection equipment adapter 100 separates from the shaft end 310 of the hollow axle 300.

[0055] Furthermore, the flaw detection feed structure 200 includes a flaw detection rod (not shown), which is disposed at the end of the flaw detection feed structure 200 facing the wheelset to be tested, and the flaw detection rod is telescopically oriented. When the hollow axle flaw detection equipment adapter 100 is connected to the hollow axle 300, the flaw detection feed structure 200 can drive the flaw detection rod through the hollow axle flaw detection equipment adapter 100 and extend into the inner cavity of the hollow axle 300 to perform flaw detection on the inner cavity of the hollow axle 300.

[0056] The hollow axle flaw detection equipment adapter 100 of this application can establish a connection between the flaw detection feed structure 200 and the hollow axle 300 of the wheelset to be tested. This allows the flaw detection feed structure 200 to connect to various hollow axles 300 of the same model via the hollow axle flaw detection equipment adapter 100, eliminating the need for an adapter on each hollow axle 300, reducing labor costs, and decreasing the number of hollow axle flaw detection equipment adapters 100, thus lowering procurement costs. Furthermore, the hollow axle flaw detection equipment adapter 100 has a simple structure, shortened axial length, and reduced weight, making it easy for operators to use.

[0057] The following describes the specific structure of the hollow axle flaw detection equipment adapter 100 in one embodiment.

[0058] See Figures 1 to 8 In one embodiment, the hollow axle flaw detection equipment adapter 100 includes a connecting plate 110 and a connecting sleeve 120. The connecting plate 110 is disposed at the end of the flaw detection feed structure 200 facing the wheelset to be tested, and the connecting plate 110 has a first flaw detection hole 111 extending through its axial direction in the middle. The connecting sleeve 120 is disposed at the end of the connecting plate 110 facing the wheelset to be tested, and the connecting sleeve 120 has a second flaw detection hole 121 extending through its axial direction.

[0059] The second flaw detection hole 121 is coaxially arranged and connected, and the end of the connecting sleeve 120 away from the connecting plate 110 is used to connect the shaft end 310 of the hollow axle 300. Figure 3 for Figure 1 The front view of the hollow axle flaw detection equipment adapter 100 shown is shown. Figure 4 for Figure 3 The cross-sectional view shown is of the hollow axle flaw detection equipment adapter 100. Figure 7 for Figure 5 The front view of the hollow axle flaw detection equipment adapter 100 shown is shown. Figure 8 for Figure 7 The cross-sectional view of the hollow axle flaw detection equipment adapter 100 shown.

[0060] The connecting plate 110 is the main component connecting the hollow axle flaw detection equipment adapter 100 to the flaw detection feed structure 200, and the connecting sleeve 120 is the main component connecting the hollow axle flaw detection equipment adapter 100 to the hollow axle 300. The connecting plate 110 is disposed on the surface of the flaw detection feed structure 200 facing the wheelset to be tested, and the connecting sleeve 120 is disposed on the end of the connecting plate 110 facing the wheelset to be tested.

[0061] Furthermore, both the connecting plate 110 and the connecting sleeve 120 have circular longitudinal cross-sectional shapes. This facilitates the connection between the connecting plate 110 and the flaw detection feed structure 200, and also facilitates the connection between the connecting sleeve 120 and the hollow axle 300. The connecting sleeve 120 is coaxially arranged with the connecting shaft, so that the flaw detection feed structure 200 can drive the flaw detection rod through the connecting plate 110 and the connecting sleeve 120 and extend into the inner cavity of the hollow axle 300.

[0062] Furthermore, the connecting disc 110 has a first flaw detection hole 111 extending through its axial direction, and the connecting sleeve 120 has a second flaw detection hole 121 extending through its axial direction. Here, the axial direction refers to the central axis of the connecting disc 110, and the circumferential direction refers to the circumferential direction of the connecting disc 110. This axial and circumferential direction also applies to the connecting sleeve 120, and will not be elaborated further below.

[0063] The first flaw detection hole 111 and the second flaw detection hole 121 are coaxially arranged and connected. When the hollow axle flaw detection equipment adapter 100 is connected to the flaw detection feed structure 200 and the hollow axle 300, the flaw detection rod of the flaw detection feed structure 200 can pass through the first flaw detection hole 111 and the second flaw detection hole 121 and extend into the inner cavity of the hollow axle 300 to perform flaw detection on the hollow axle 300.

[0064] The hollow axle flaw detection equipment adapter 100 of this application is equivalent to an adapter, which can directly connect the flaw detection feed structure 200 to the hollow axle 300 of the wheelset to be tested. The hollow axle flaw detection equipment adapter 100 of this application has a simple structure. It directly connects to the axle end 310 of the hollow axle 300 through the connecting sleeve 120, which greatly reduces the overall length and weight of the hollow axle flaw detection equipment adapter 100.

[0065] Meanwhile, the hollow axle flaw detection equipment adapter 100 of this application is set on the flaw detection feed structure 200. The shaft ends 310 of each hollow axle 300 of the same model are connected through the connecting sleeve 120 of the hollow axle flaw detection equipment adapter 100. It is not necessary to set the hollow axle flaw detection equipment adapter 100 on each hollow axle 300, thereby reducing the number of hollow axle flaw detection equipment adapters 100 and eliminating the step of connecting the hollow axle flaw detection equipment adapter 100 to the hollow axle 300.

[0066] The hollow axle flaw detection equipment adapter 100 of the above embodiment connects to the flaw detection feed structure 200 via a connecting plate 110 and to the shaft end 310 of the hollow axle 300 via a connecting sleeve 120, thereby establishing a connection between the flaw detection feed structure 200 and the hollow axle 300 of the wheelset to be tested. In this way, the flaw detection feed structure 200 can connect to various hollow axles 300 of the same model via the hollow axle flaw detection equipment adapter 100, eliminating the need to install an adapter on each hollow axle 300, reducing labor costs, and reducing the number of hollow axle flaw detection equipment adapters 100, thus lowering procurement costs. At the same time, the hollow axle flaw detection equipment adapter 100 has a simple structure, shortened axial length, and reduced weight, making it easy for operators to use.

[0067] In one embodiment, the connecting plate 110 and the connecting sleeve 120 are an integral structure. This ensures the structural strength of the connection between the connecting plate 110 and the connecting sleeve 120, thereby ensuring that the hollow axle flaw detection equipment adapter 100 can accurately connect the flaw detection feed structure 200 and the hollow axle 300, facilitating the flaw detection feed structure 200 to perform flaw detection on the hollow axle 300.

[0068] Of course, in other embodiments of this application, the connecting plate 110 and the connecting sleeve 120 may also be separately provided and reliably connected by means of threaded connection, welding or other methods.

[0069] See 1. Figure 2 , Figure 5 and Figure 6 In one embodiment, the flaw detection feed structure 200 further includes a mounting plate 210, which is disposed at one end of the flaw detection feed structure 200 facing the wheelset to be tested. The mounting plate 210 is used to mount the connecting plate 110 of the hollow axle flaw detection equipment adapter 100.

[0070] The mounting plate 210 is hollow, and the connecting plate 110 of the hollow axle flaw detection equipment adapter 100 can be installed into the mounting plate 210. Furthermore, the edge of the connecting plate 110 can engage with the edge of the mounting plate 210. The mounting plate 210 enables the installation and fixation of the connecting plate 110, so that the connecting plate 110 is reliably fixed to the flaw detection feed structure 200.

[0071] See Figures 1 to 8 In one embodiment, the hollow axle flaw detection equipment adapter 100 further includes a limiting member 130, which is disposed on the connecting plate 110. The limiting member 130 can be installed in the limiting groove 211 of the flaw detection feed structure 200 so that the connecting plate 110 is positioned on the flaw detection feed structure 200.

[0072] The limiting member 130 is disposed on the surface of the connecting plate 110 facing the flaw detection feed structure 200. The limiting member 130 can realize the installation positioning between the hollow axle flaw detection equipment adapter 100 and the flaw detection feed structure 200, so as to ensure that the hollow axle flaw detection equipment adapter 100 is accurately installed on the flaw detection feed structure 200, thereby enabling the connecting sleeve 120 to accurately align with the shaft end 310 of the hollow axle 300, thereby ensuring the accuracy of the flaw detection results.

[0073] Specifically, the mounting plate 210 of the flaw detection feed structure 200 has a limiting groove 211, which is recessed into the connecting plate 110 and corresponds to the position of the limiting member 130 on the connecting plate 110. Thus, when installing the hollow axle flaw detection equipment adapter 100 onto the mounting plate 210, the limiting member 130 is first aligned with the limiting groove 211, and then the connecting plate 110 is pushed into the mounting plate 210, so that the limiting member 130 is installed in the limiting groove 211, achieving accurate installation between the connecting plate 110 and the mounting plate 210.

[0074] See Figures 1 to 8 In one embodiment, the limiting member 130 is disposed on the edge of the connecting disk 110 and protrudes from the outer peripheral surface of the connecting disk 110. That is, the limiting member 130 is disposed on the edge of the surface of the connecting disk 110 facing the flaw detection feed structure 200 and extends radially along the connecting disk 110, with the limiting member 130 protruding from the outer peripheral surface of the connecting disk 110.

[0075] Thus, through the positioning and cooperation of the limiting member 130 with the limiting groove 211 of the mounting plate 210, the connecting plate 110 can be accurately installed into the mounting plate 210. At the same time, the limiting member 130 is located on the outer periphery of the connecting plate 110, which facilitates the correspondence between the limiting member 130 and the limiting groove 211, thereby ensuring the accuracy of the installation of the connecting plate 110.

[0076] See Figure 3 and Figure 4 In one embodiment, the limiting member 130 and the connecting plate 110 are an integral structure. That is, the limiting member 130 and the connecting plate 110 are integrally formed. This ensures the accurate positioning of the limiting member 130 relative to the connecting plate 110, thereby ensuring the accurate installation of the connecting plate 110, and at the same time, simplifies the assembly process.

[0077] See Figure 7 and Figure 8In one embodiment, the limiting member 130 is separately disposed from the connecting plate 110. The edge of the connecting plate 110 facing the flaw detection feed structure 200 has a recess, the limiting member 130 is disposed in the recess, and the limiting member 130 is reliably fixed to the connecting plate 110 by fasteners such as screws. In this way, the positioning of the connecting plate 110 can also be achieved.

[0078] See Figures 1 to 8 In one embodiment, the hollow axle flaw detection equipment adapter 100 further includes a positioning member 140. The connecting plate 110 has a first positioning hole 112, and the flaw detection feed structure 200 has a second positioning hole (not shown). The first positioning hole 112 and the second positioning hole are coaxially arranged, and the positioning member 140 passes through the first positioning hole 112 and is installed in the second positioning hole.

[0079] The connecting plate 110 has a first positioning hole 112 extending through it along its axial direction, and the first positioning hole 112 is located on the side of the first flaw detection hole 111. The mounting plate 210 has a second positioning hole extending along its axial direction, and the first positioning hole 112 and the second positioning hole are correspondingly provided. The positioning member 140 can be positioned and engaged with the first positioning hole 112 and the second positioning hole to further ensure the accuracy of the installation of the connecting plate 110.

[0080] When installing the hollow axle flaw detector adapter 100 onto the mounting plate 210, first align the positioning member 140 with the limiting groove 211, then push the connecting plate 110 into the mounting plate 210 so that the positioning member 140 is installed in the limiting groove 211. At this time, the first positioning hole 112 and the second positioning hole are aligned. Subsequently, the end of the positioning member 140 is inserted through the first positioning hole 112 and installed into the second positioning hole. In this way, the positioning member 140 can further position the connecting plate 110, achieving accurate installation between the connecting plate 110 and the mounting plate 210.

[0081] See Figure 4 and Figure 8 In one embodiment, the hollow axle flaw detection equipment adapter 100 further includes a locking component 150, which is disposed on the positioning member 140. The locking component 150 can limit the installation of the positioning member 140, and at the same time, it can reliably fix the connecting plate 110 to the mounting plate 210.

[0082] See Figure 4 and Figure 8In one embodiment, the locking assembly 150 includes a threaded member 151 and a stop member 152. The threaded member 151 is disposed on the outside of the positioning member 140. The stop member 152 is rotatably disposed on the threaded member 151. The stop member 152 is used to limit the distance by which the positioning member 140 extends into the second positioning hole and can abut against the end face of the connecting disc 110.

[0083] The threaded part 151 is sleeved on the outside of the positioning part 140, and the stop part 152 is sleeved on the threaded part 151. When the positioning part 140 is installed into the second positioning hole through the first positioning hole 112, the threaded part 151 can be located in the first positioning hole 112, and the stop part 152 can rotate along the threaded part 151 and fit against the surface of the connecting plate 110 to limit the distance that the positioning part 140 extends into the first positioning hole 112.

[0084] Meanwhile, the stop 152 can also restrict the positioning member 140 to prevent the positioning member 140 from slipping out of the first positioning hole 112, so that the positioning member 140 can be reliably installed into the first positioning hole 112 and the second positioning hole, thereby achieving reliable positioning of the connecting plate 110 and the mounting plate 210.

[0085] Optionally, the stop 152 is a nut, and the threaded part 151 is a threaded cylinder. Optionally, the positioning part 140 is a pin. Of course, in other embodiments of this application, the positioning part 140 may also be a positioning rod or other structure that can cooperate with the first positioning hole 112 and the second positioning hole for positioning.

[0086] See Figure 1 , Figure 2 , Figure 5 and Figure 6 In one embodiment, the connecting disc 110 further includes an anti-detachment portion 113, which is disposed on the surface of the connecting disc 110 facing the connecting sleeve 120. The anti-detachment portion 113 is used to connect the tension lock 220 of the flaw detection feed structure 200.

[0087] The flaw detection feed structure 200 also includes a tension lock 220, one end of which is movably disposed on the flaw detection feed structure 200, and the other end has a hook portion, which is used to hook the anti-detachment portion 113 of the hollow axle flaw detection equipment adapter 100.

[0088] The anti-detachment part 113 is provided on the surface of the connecting plate 110 away from the flaw detection feed structure 200. After the anti-detachment part 113 cooperates with the tension lock 220 of the flaw detection feed structure 200, the connecting plate 110 can be locked and fixed in the mounting plate 210 to prevent the connecting plate 110 from falling out of the mounting plate 210.

[0089] After the connecting plate 110 is installed onto the mounting plate 210, tighten the tension lock 220 and hook the hook at the front end of the tension lock 220 onto the anti-detachment part 113 to lock the connecting plate 110 to the front end of the flaw detection feed structure 200, thus completing the installation of the hollow axle flaw detection equipment adapter 100 and reliably fixing the connecting plate 110 into the mounting plate 210 to prevent the position of the connecting plate 110 from shifting.

[0090] In this embodiment, the anti-detachment part 113 is a groove. Of course, in other embodiments of this application, the anti-detachment part 113 may also be a protrusion, a buckle, or other structure that can cooperate with the tension lock 220 to lock.

[0091] In this embodiment, there are two anti-detachment parts 113, which are symmetrically arranged on both sides of the connecting plate 110. Correspondingly, there are also two tension locks 220, which are symmetrically arranged. Each tension lock 220 cooperates with the corresponding anti-detachment part 113.

[0092] Of course, in other embodiments of this application, the anti-detachment part 113 may be one or other numbers, and the number of tension locks 220 may be adapted to the number of anti-detachment parts 113.

[0093] See Figures 1 to 4 In the first embodiment of this application, the connecting sleeve 120 has a connecting end 122 at the end away from the connecting disk 110, and the diameter of the connecting end 122 gradually decreases from the end near the connecting disk 110 to the end away from the connecting disk 110. The connecting end 122 is used to connect to the flared portion 320 of the shaft end 310.

[0094] In this embodiment, the inner hole at the end where the hollow axle 300 connects to the connecting sleeve 120 is a smooth hole. At this time, the connecting sleeve 120 directly connects to the shaft end 310 of the hollow axle 300 via the connecting end 122. Thus, the flaw detection rod of the flaw detection feed structure 200 can directly pass through the connecting plate 110 and extend into the hollow axle 300 via the connecting sleeve 120.

[0095] Furthermore, the diameter of the connecting end 122 gradually decreases from the end closer to the connecting plate 110 to the end farther away from the connecting plate 110. In other words, the connecting end 122 is tapered. In this way, when the hollow axle flaw detection equipment adapter 100 is connected to the hollow axle 300, the connecting end 122 fits perfectly into the flared portion 320 of the hollow axle 300, ensuring accurate connection between the connecting sleeve 120 and the hollow axle 300.

[0096] In this embodiment, when the hollow axle flaw detection equipment adapter 100 is installed onto the flaw detection feed structure 200, the positioning member 140 on the connecting plate 110 is aligned with the limiting groove 211 of the mounting plate 210 of the flaw detection feed structure 200. The connecting plate 110 is then pushed into the mounting plate 210. At this time, the first positioning hole 112 of the connecting plate 110 is aligned with the second positioning hole of the mounting plate 210. Subsequently, the positioning member 140 is inserted through the first positioning hole 112 and installed into the second positioning hole, thus completing the alignment of the connecting plate 110 and the mounting plate 210.

[0097] Subsequently, tighten the tension lock 220, hooking the front end of the tension lock 220 onto the anti-detachment part 113, and lock the hollow axle flaw detection equipment adapter 100 to the mounting plate 210 at the front end of the flaw detection feed structure 200, completing the installation of the hollow axle flaw detection equipment adapter 100. Then, the connecting sleeve 120 can be used to connect to the shaft end 310 of the hollow axle 300 to perform flaw detection on the hollow axle 300. After flaw detection, the process of disassembling the hollow axle flaw detection equipment adapter 100 is the reverse process of the above-described installation of the hollow axle flaw detection equipment adapter 100, and will not be described again below.

[0098] See Figures 5 to 8 In the second embodiment of this application, the hollow axle flaw detection equipment adapter 100 further includes a threaded sleeve 160. The connecting sleeve 120 has a first threaded portion 123 facing the outer wall of the hollow axle 300. The threaded sleeve 160 has a second threaded portion 161 near the inner wall of the connecting sleeve 120, and a third threaded portion 162 away from the outer wall of the connecting sleeve 120. The threaded sleeve 160 is connected to the connecting sleeve 120 through the engagement of the second threaded portion 161 and the first threaded portion 123, and the threaded sleeve 160 is connected to the hollow axle 300 through the third threaded portion 162.

[0099] In this embodiment, the inner hole at the end where the hollow axle 300 connects to the connecting sleeve 120 is a threaded hole, that is, the hollow axle 300 is a threaded shaft. At this time, the outer wall of the connecting sleeve 120 has an external thread, which is the first threaded part 123, and the threaded sleeve 160 has an internal thread and an external thread, which are the second threaded part 161 and the third threaded part 162, respectively.

[0100] The threaded sleeve 160 is screwed into the connecting sleeve 120 through the engagement of the second threaded portion 161 and the first threaded portion 123. The threaded sleeve 160 is screwed into the threaded hole of the hollow axle 300 through the third threaded portion 162, so that the threaded sleeve 160 is installed on the shaft end 310 of the hollow axle 300.

[0101] Thus, in this embodiment, the hollow axle flaw detection equipment adapter 100 directly connects to the shaft end 310 of the hollow axle 300 via the threaded sleeve 160. This allows the flaw detection rod of the flaw detection feed structure 200 to directly pass through the connecting plate 110, connecting sleeve 120, and threaded sleeve 160 into the hollow axle 300. When the threaded sleeve 160 is damaged, it can be directly unscrewed and replaced with a new one, reducing the cost of the hollow axle flaw detection equipment adapter 100.

[0102] In this embodiment, when the hollow axle flaw detection equipment adapter 100 is installed onto the flaw detection feed structure 200, the positioning member 140 on the connecting plate 110 is aligned with the limiting groove 211 of the mounting plate 210 of the flaw detection feed structure 200. The connecting plate 110 is then pushed into the mounting plate 210. At this time, the first positioning hole 112 of the connecting plate 110 is aligned with the second positioning hole of the mounting plate 210. Subsequently, the positioning member 140 is inserted through the first positioning hole 112 and installed into the second positioning hole, thus completing the alignment of the connecting plate 110 and the mounting plate 210.

[0103] Subsequently, tighten the tension lock 220, hooking the front end of the tension lock 220 onto the anti-detachment part 113, and lock the hollow axle flaw detection equipment adapter 100 to the mounting plate 210 at the front end of the flaw detection feed structure 200, completing the installation of the hollow axle flaw detection equipment adapter 100. Then, the connecting sleeve 120 can be used to connect to the shaft end 310 of the hollow axle 300 to perform flaw detection on the hollow axle 300. After flaw detection, the process of disassembling the hollow axle flaw detection equipment adapter 100 is the reverse process of the above-described installation of the hollow axle flaw detection equipment adapter 100, and will not be described again below.

[0104] It is worth noting that the hollow axle flaw detection equipment adapter 100 of the first embodiment is substantially the same as that of the hollow axle flaw detection equipment adapter 100 of the second embodiment. The only difference is that the hollow axle flaw detection equipment adapter 100 of the second embodiment has an additional threaded sleeve 160 for connecting the hollow axle 300 with threads, while the hollow axle flaw detection equipment adapter 100 of the first embodiment directly connects to the hollow axle 300 with a light hole. The rest of the hollow axle flaw detection equipment adapter 100 of the first embodiment and the hollow axle flaw detection equipment adapter 100 of the second embodiment are the same.

[0105] The hollow axle flaw detection equipment adapter 100 of this application directly establishes a connection between the flaw detection feed structure 200 and the hollow axle 300 of the wheelset to be tested. Thus, the flaw detection feed structure 200 can connect to various hollow axles 300 of the same model via the hollow axle flaw detection equipment adapter 100, eliminating the need for an adapter on each hollow axle 300, reducing labor costs, and reducing the number of hollow axle flaw detection equipment adapters 100, thereby lowering procurement costs. Simultaneously, the hollow axle flaw detection equipment adapter 100 has a simple structure, a shortened axial length, saves storage space, reduces weight, and is easy for operators to use.

[0106] This application also provides a hollow axle flaw detection feeding device, including a flaw detection feeding structure 200 and a hollow axle flaw detection equipment adapter 100 as described in any of the above embodiments. The hollow axle flaw detection equipment adapter 100 is disposed at one end of the flaw detection feeding structure 200 and can be connected to the hollow axle 300 of the wheelset to be tested. The hollow axle flaw detection feeding device has a flaw detection rod, which can pass through the hollow axle flaw detection equipment adapter 100 and extend into the hollow axle 300 to detect flaws in the hollow axle 300.

[0107] It is worth noting that the specific structure and flaw detection principle of the flaw detection feed structure 200 are existing technologies and will not be described in detail later.

[0108] The hollow axle flaw detection feed device of this application, after adopting the hollow axle flaw detection equipment adapter 100 of the above embodiment, can connect with the hollow axle 300 of the wheelset to be tested, and realize flaw detection of the hollow axle 300. At the same time, the hollow axle flaw detection feed device can connect various hollow axles 300 of the same model through connecting bone sections, eliminating the need to install an adapter on each hollow axle 300, reducing labor costs, reducing the number of hollow axle flaw detection equipment adapters 100, reducing procurement costs, and facilitating operation by operators.

[0109] See Figure 2 and Figure 6 In one embodiment, the top of the flaw detection feed structure 200 has a movable handle 230, which is used to move the flaw detection feed structure 200. The movable handle 230 is located on the top of the flaw detection feed structure 200, making it convenient for operators to move the flaw detection feed structure 200 to the required position.

[0110] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0111] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
