[0002] When assembling the bogie of an urban rail vehicle, the air springs need to be assembled after the bogie is completed. Before assembly, lubricating grease needs to be applied to the air spring guide column, and the air spring cavity needs to be checked for foreign objects.

[0003] However, after the air springs arrive, two air springs are stacked together. Before assembling the upper air spring, it is impossible to check whether there are foreign objects in the inner cavity. After being hoisted to the frame, it is also impossible to check on the bogie platform. Only after the frame is transferred to the next process can a special person conduct an inspection, which wastes manpower and cannot guarantee the assembly quality.

[0028] like Figures 1 to 2 As shown, this utility model embodiment provides an air spring detection device, including a first support base 100 and a second support base 200. The first end and the second end of the second support base 200 are distributed along the axial direction of the second support base 200. The first end is used to support the air spring, and the second end is rotatably connected to the first support base 100 through a rotating component 300.

[0029] The air spring testing device of this utility model mainly consists of a first support base 100 and a second support base 200. The first support base 100 and the second support base 200 are rotatably connected by a rotating component 300, that is, the first support base 100, the rotating component 300, and the second support base 200 are coaxially arranged. The second support base 200 has a first end and a second end at its two ends in the axial direction. The first end contacts and supports the air spring to be tested, and the rotating component 300 is arranged between the second end and the first support base 100 to realize the rotatable connection between the second support base 200 and the first support base 100, so that the second support base 200 can rotate around the axis on the first support base.

[0030] This invention addresses the needs of pre-construction preparation and on-site testing of air springs. Through analysis of the work site, a convenient air spring testing device is designed and manufactured. The air spring to be tested is placed on a second support base 200. The second support base 200 not only supports and fixes the air spring but also allows it to rotate 360°, achieving omnidirectional testing. This invention solves the problems of difficult air spring testing methods and complex construction. Its simple structure makes it suitable for work environments where the device is easy to handle, lightweight, and occupies little space. It saves work space, is highly mobile, reduces the cost of manufacturing large devices and the time required for multiple people to move large devices, improves work efficiency, and ensures assembly quality.

[0031] Before assembling the air spring, lithium-based No. 3 lubricating grease needs to be applied to the air spring guide post. This cannot be applied inside the tooling and can only be applied during hoisting, which violates hoisting management regulations and poses a safety hazard.

[0032] According to one embodiment of the present invention, the second support 200 is provided with a positioning hole 210 extending along its axial direction, and the side wall of the support is formed with a hollow portion 220 communicating with the positioning hole 210.

[0033] In this embodiment, the second support base 200 can be an integral structure, generally cylindrical. When the air spring is placed on the second support base 200, the air spring guide column to be tested can be inserted into the positioning hole 210 in the middle of the second support base 200. The side wall of the second support base 200 is provided with a hollow part 220, which extends towards and communicates with the positioning hole 210. The operator can enter the positioning hole 210 through the hollow part 220 to apply lubricant to the air spring guide column. Thus, this utility model realizes the preparation and testing work before air spring assembly, achieves the functions of applying lubricant to the air spring guide column and testing the air spring, and also realizes the advantages of rapid device movement and small site occupation area.

[0034] According to one embodiment of the present invention, the second support base 200 includes a first support plate 230, a second support plate 240, and a column 250. The first support plate 230 is adapted to support an air spring and has a first through hole 231. The second support plate 240 corresponds to and is arranged parallel to the first support plate 230. The second support plate 240 is rotatably connected to the first support base 100 via a rotating component 300. One end of the column 250 is connected to the first support plate 230, and the other end is connected to the second support plate 240.

[0035] In this embodiment, the second support base 200 mainly consists of a first support plate 230, a second support plate 240, and a column 250. The first support plate 230, the column 250, and the second support plate 240 are arranged sequentially along the axial direction of the second support base 200. Therefore, the first support plate 230 is the first end of the second support base 200, and the second support plate 240 is the second end of the second support base 200. The first support plate 230 and the second support plate 240 are arranged opposite to each other and remain parallel to each other. The column 250 supports the first support plate 230. The first support plate 230 is connected to the second support plate 240. A first through hole 231 is provided in the middle of the first support plate 230, making the first support plate 230 a ring structure. Multiple columns 250 are also distributed along the ring and connected to the second support plate 240. Thus, the space between two adjacent columns 250 can be a hollow part 220. After the first through hole 231 of the first support plate 230 is connected to the space enclosed by the column 250, a positioning hole 210 is formed. Alternatively, a second support base 200 structure can be formed where the hollow part 220 and the positioning hole 210 are connected.

[0036] In this embodiment, there are four columns 250, which are evenly distributed between the first support plate 230 and the second support plate 240. The first support plate 230, the columns 250 and the second support plate 240 are arranged sequentially from top to bottom. The hollow part 220 formed by the columns 250 has a larger space, making it more convenient to check the air spring and apply lubricant to the guide column.

[0037] According to one embodiment of the present invention, the column 250 is threadedly connected to at least one of the first support plate 230 and the second support plate 240.

[0038] In this embodiment, both ends of the column 250 are provided with threads, and the first support plate 230 and the second support plate 240 are provided with corresponding threaded holes. After aligning the two ends of the column 250 with the threaded holes of the first support plate 230 and the second support plate 240, the column 250 is screwed in so that the two ends of the column 250 are screwed into the threaded holes of the first support plate 230 and the second support plate 240, thus completing the connection of the first support plate 230, the column 250 and the second support plate 240.

[0039] Furthermore, the threaded connection can also adjust the distance between the first support plate 230 and the second support plate 240. That is, by screwing the column 250, the threaded end on the column 250 can be screwed out or screwed into the threaded hole of the first support plate 230 or the threaded hole of the second support plate 240, thereby changing the length of the column 250 between the first support plate 230 and the second support plate 240, and thus changing the height position of the first support plate 230 relative to the second support plate 240. This can be applied to different models of air springs.

[0040] In other embodiments, the column 250 may have a thread on only one end, and the support plate connected to the threaded end may have a threaded hole, while the other support plate may have a smooth hole for insertion into the other end of the column 250.

[0041] According to one embodiment of the present invention, the second support base 200 further includes a limiting post 260, the limiting post 260 is disposed on the second support plate 240, the first support base 100 is provided with a limiting hole 110, and the limiting post 260 is inserted into the limiting hole 110.

[0042] In this embodiment, the second support base 200 mainly consists of a first support plate 230, a column 250, a second support plate 240, and a limiting post 260. The first support plate 230, the column 250, the second support plate 240, and the limiting post 260 are arranged sequentially from top to bottom. The first support base 100 is located below the second support plate 240. The first support base 100 is provided with a limiting hole 110 that cooperates with the limiting post 260. The second support base 200 is detachably connected to the first support base 100.

[0043] When the second support 200 is placed on the first support 100, the limiting post 260 is inserted into the limiting hole 110, which can maintain the stable installation of the second support 200 on the first support 100. The cooperation between the limiting post 260 and the limiting hole 110 can ensure the relative positioning of the first support 100 and the second support 200 in the horizontal direction, and prevent the second support 200 from shifting horizontally on the first support 100.

[0044] According to one embodiment of the present invention, the second support plate 240 is provided with a second through hole 241, and the limiting post 260 is provided with a third through hole 261 extending along its axial direction, and the second through hole 241 and the third through hole 261 are connected.

[0045] In this embodiment, the second support plate 240 is provided with a second through hole 241 along the axial direction of the second support base 200, and the limiting post 260 is provided with a third through hole 261 along the axial direction of the second support base 200. Therefore, the second support base 200 is connected from top to bottom along its axial direction by the first through hole 231, the space between the post 250, the second through hole 241, and the third through hole 261 to form a through connection. Through the second through hole 241 of the second support plate 240 and the third through hole 261 of the limiting post 260, the extension space of the air spring guide post is increased, while the overall weight of the second support base 200 is reduced, making it convenient for disassembly, installation, and transportation.

[0046] According to one embodiment of the present invention, the rotating component 300 is arranged around the limiting hole 110.

[0047] In this embodiment, the rotating component 300 is arranged in a ring around the limiting hole 110. Thus, when the second support 200 rotates on the first support 100 via the rotating component 300, the limiting post 260 always rotates synchronously within the limiting hole 110, thereby limiting and stabilizing the second support 200. This is equivalent to the second support 200 rotating around the limiting post 260.

[0048] According to one embodiment of the present invention, the rotating component 300 includes a mounting base 310 and a rolling part 320. The mounting base 310 is provided with a groove and is disposed on one of the first support base 100 and the second support plate 240. The rolling part 320 is partially disposed in the groove, and the portion protruding from the groove makes rolling contact with the other of the first support base 100 and the second support plate 240.

[0049] In this embodiment, the rotating component 300 mainly consists of a mounting base 310 and a rolling part 320. The mounting base 310 has a groove, and the rolling part 320 can be embedded in the groove and roll within it. Only a portion of the rolling part 320 is located within the groove, while the remaining portion protrudes from the groove opening. The mounting base 310 is connected to one of the first support base 100 and the second support plate 240, while the portion of the rolling part 320 protruding from the groove contacts the other of the first support base 100 and the second support plate 240. The rotating component 300 can be mounted on either the first support base 100 or the second support base 200. When the second support base 200 rotates on the first support base 100, the rolling part 320 rolls within the groove.

[0050] In this embodiment, the rolling part 320 is a rolling ball, and the groove of the mounting base 310 is a spherical groove. One mounting base 310 corresponds to one rolling ball to form a rotating component 300, and multiple rotating components 300 are evenly distributed around the limiting hole 110. The rotating part of the rolling ball makes the rotational engagement between the second support base 200 and the first support base 100 more flexible and reliable. In other embodiments, the mounting base 310 can also be an annular structure, with an annular groove arranged around the limiting hole 110, and the rolling part 320 can be a cylindrical roller, which can also achieve the rotational engagement between the second support base 200 and the first support base 100.

[0051] According to one embodiment of the present invention, the mounting base 310 is disposed on the first support base 100, and the rolling part 320 is in rolling contact with the second support plate 240.

[0052] In this embodiment, the mounting base 310 is disposed on the first support base 100 and can be connected by bolts. The rolling part 320 protrudes from the groove and contacts the second support plate 240. Thus, the rotating part 300 is disposed on the first support base 100. The mounting base 310 is equivalent to supporting the rolling part 320 from below, making the installation and rolling of the rolling part 320 more stable. When the second support base 200 is installed on the first support base 100, the second support plate 240 falls above the rolling part 320.

[0053] In other embodiments, the rotating component 300 is disposed on the second support 200, and the mounting base 310 is equivalent to wrapping the rolling part 320 above it. The mounting base 310 is disposed on the second support plate 240 and can be connected by bolts. When the second support 200 is installed on the first support 100, the rolling part 320 falls on the first support 100.

[0054] According to one embodiment of the present invention, the rotating component 300 further includes a mounting plate 330, on one side of which a mounting base 310 is mounted, and on the other side which is connected to the first support base 100.

[0055] In this embodiment, the rotating component 300 mainly consists of a mounting base 310, a rolling part 320, and a mounting plate 330. When the rotating component 300 is installed on the first support base 100, all the mounting bases 310 are fixed to one side of the mounting plate 330, and the other side of the mounting plate 330 is connected to the first support base 100. Thus, the mounting plate 330 integrates all the mounting bases 310 into a single component, facilitating installation and removal on the first support base 100.

[0056] According to one embodiment of the present invention, the first support base 100 is composed of a column 140, a third support plate 120 and a fourth support plate 130. The third support plate 120 and the fourth support plate 130 are supported and connected by four columns 140. The fourth support plate 130 has a circular structure, which reduces the weight of the overall component. The surface area of ​​the fourth support plate 130 is larger than that of the third support plate 120, thereby increasing the contact area between the first support base 100 and the ground.

[0057] In use, the rotating component 300 is placed above the third support plate 120 of the first support base 100, and the second support plate 240 of the second support base is placed on the rotating component, and positioned by the limiting post 260.

[0058] When inspecting and applying grease to the air spring, the air spring is placed above the first support plate 230 of the second support base 200. The air spring is inspected through the hollow structure of the column 250 and the rotation of the rolling part 320. When applying grease to the air spring guide column, it can be applied directly through the hollow between the columns 250, achieving the preparation work before inspection and assembly.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
