Description

Technical Field

[0002] The bogie assembly process for rail vehicles refers to the process of assembling key components such as wheelsets, axle boxes, suspension systems, traction devices, and braking systems into a complete bogie according to process requirements. It is the core process of rail vehicle manufacturing and directly determines the safety and comfort of vehicle operation.

[0003] In the bogie installation process, not only is accurate positioning and assembly of each component required, but also measurement and adjustment of wheelset positioning parameters and assembly precision. After installation, the bogie must undergo no-load testing and performance verification to confirm its flexible operation and reliable braking. Therefore, as a key component connecting the car body and the track, high-quality bogie installation is fundamental to ensuring the high-speed, stable, and safe operation of rail vehicles, and is also one of the core aspects of rail equipment manufacturing.

[0004] The existing bogie installation process has at least the following problems: During bogie installation, it is impossible to guarantee accurate alignment between the various parts of the wheelset axle boxes and their corresponding positions on the frame, making components prone to collision damage during frame descent. In particular, if the two sets of wheelsets are not on the same plane during frame descent, it is highly likely that the wheelset axle box positioning nodes will not be correctly embedded into the frame positioning nodes.

[0005] Especially during the adjustment and testing phase after completion, if the bogie is used for a different model, the existing platform may not be able to accurately support the axle box due to inconsistent wheelbase, requiring frequent adjustments and replacements of the support mechanism, which increases the difficulty of adjustment and testing. More importantly, in the process of diagonal measurement, coupling assembly, and wheelset fixing, it is impossible to effectively and accurately fix and position the wheelset.

[0036] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0037] like Figures 1 to 7As shown, the bogie assembly and adjustment device of the present invention includes an assembly platform 100 and an adjustment platform 200. The assembly platform 100 is used during the assembly stage of the bogie assembly process to achieve relative positioning of the two sets of wheelsets by calibrating and positioning the inner surfaces of the wheel bodies of the two sets of wheelsets. By locking and supporting each axle box and adjusting its height, it ensures that the positioning nodes of each axle box are on the same assembly plane, thereby enabling the two sets of wheelsets to be accurately positioned on the centerline of the track 130 before the frame assembly is completed, improving the accuracy of subsequent frame assembly and installation. The adjustment platform 200 is located at the next step after the assembly platform 100. After the frame assembly and installation are completed, the adjustment platform 200 suspends the bogie by supporting the axle boxes and locks and fixes the two sets of wheelsets of the bogie respectively. Furthermore, the adjustment platform 200 can be flexibly adjusted based on the different wheelbases of the two sets of wheelsets of the bogie, improving the device's adaptability to bogies of different wheelbase models. Therefore, the device described in this embodiment of the invention can realize the rapid connection between the wheelset axle box assembly and the frame assembly, and has the universality of multiple vehicle models (including different wheelbases and / or inner distances), realize the bogie assembly precision control and dimensional adjustment precision control, realize the stability improvement of the bogie assembly connection, thereby realizing the precise assembly of each component after the bogie is assembled and meeting the mating dimensional relationship.

[0038] In the apparatus of this embodiment of the invention, such as Figure 1 and Figure 4 As shown, the adjustment platform 200 includes a two-way locking mechanism 230. Two-way locking mechanisms 230 are respectively provided between the wheels of the two sets of wheelsets of the bogie. The two-way locking mechanisms 230 are adapted to lock the wheelsets to a stationary state at any stage of bogie assembly. Therefore, during bogie assembly, this bogie assembly adjustment device can effectively and accurately fix and position the wheelsets through the two-way locking mechanisms 230, significantly improving the operational accuracy and efficiency of the bogie assembly process.

[0039] It should be noted that the bogie described in this embodiment of the invention is preferably a swing arm type bogie. The bogie comprises a frame and two sets of wheelset axle boxes. The two sets of wheelset axle boxes are respectively connected to the front and rear ends of the frame. Each set of wheelset axle boxes includes a wheelset and an axle box body, with the axle box body mounted on the axle ends on both sides of the wheelset. The axle box bodies are respectively connected to positioning nodes via swing arms. In the two sets of wheelset axle box assemblies, the swing arms of the two sets of axle box bodies face the side beams on the corresponding sides of the frame.

[0040] It should be noted that the bogie installation and adjustment device described in this embodiment of the invention is applied to the complete bogie installation process and can perform the following bogie installation and adjustment method. The bogie installation process mainly includes an installation stage and an adjustment and testing stage. The operation procedures involved in the installation stage include, but are not limited to, positioning and placing the wheelset axle box components in the corresponding positions, selecting and assembling axle box springs, supporting and positioning the axle box positioning nodes, installing and connecting the frame, connecting the positioning arm of the swingarm bogie, lifting the wheelset, connecting the suspension components such as the shock absorber and traction motor, connecting the drive unit coupling, and assembling the wheel flange lubrication system. Furthermore, the wheelset positioning parameters and assembly accuracy are measured and adjusted during the installation stage. All the operation procedures in the above installation stage can be completed at the installation platform 100. In the adjustment and testing stage after installation, the bogie can be reliably suspended using the adjustment platform 200, thereby performing no-load testing and performance verification of the bogie to confirm that the bogie operates flexibly and brakes reliably. Therefore, as a key component connecting the car body and the track, the completion of a high-quality bogie is the foundation for ensuring the high-speed, stable, and safe operation of rail vehicles, and is also one of the core links in rail equipment manufacturing.

[0041] It should be noted that, in this invention, "front" and "rear" refer to the length direction of the bogie, i.e., the vehicle length direction; "left" and "right" refer to the width direction of the bogie, i.e., the vehicle width direction, i.e., the two sides of the axle end of the wheelset; "up," "down," "raise," and "lower" all refer to the height direction of the bogie, i.e., the vehicle height direction. "Inner side" refers to the direction inside the vehicle; conversely, "outer side" refers to the direction outside the vehicle, i.e., the direction of the axle end of the wheelset.

[0042] The following is for reference Figure 2 and Figure 3 The placement platform 100 described in the apparatus of this embodiment will be described in detail.

[0043] In some embodiments, such as Figure 2 As shown, the bogie erection platform 100 includes an erection platform 110, multiple erection support mechanisms 120, and multiple baffles 140. During the bogie erection process, the erection platform 100 uses the erection platform 110 to determine the bogie's erection reference surface, utilizes the baffles 140 to calibrate the wheelsets, and uses the erection support mechanisms 120 to support and position the positioning nodes of the axle box bodies. This ensures that the axes of the two sets of wheelsets remain in a rectangular state relative to the frame, thereby ensuring the smooth erection, connection, and assembly of the wheelset axle box components with the frame, avoiding difficulties such as resistance, component damage, and the inability to embed certain parts during the connection process.

[0044] In some specific embodiments, such as Figure 2As shown, the upper surface of the bogie placement platform 110 serves as the main platform for bogie placement, providing support and a working platform for bogie assembly, as well as a reference for bogie assembly. The platform's planar accuracy is controlled within 0.02mm, effectively ensuring the reference for bogie assembly. The placement platform 110 is equipped with tracks 130, which are used for bearing, transporting, and positioning wheelsets. Preferably, the tracks 130 are fixed to the placement platform 110 with bolts, allowing for the placement of bogies with different inner distances for different vehicle models. The bogie inner distance, also known as the wheelset inner distance, refers to the minimum distance between the inner surfaces of the left and right wheelsets in the same wheelset. The tracks 130 are laid with two rails according to the specific requirements of the bogie wheelbase or inner distance, ensuring that the two wheelsets can bear the load on both rails.

[0045] In some specific embodiments, such as Figure 2 As shown, multiple baffles 140 are disposed on the platform 110, and each baffle 140 is arranged parallel to the track 130. The multiple baffles 140 are used for calibration and positioning of the wheelsets. Preferably, each baffle 140 is fixed to the inner side of the track 130 to facilitate reliable calibration of the inner distance of the wheelsets. Preferably, at least one wheel of the wheelset has a baffle 140 on its inner surface, and at least two baffles 140 are located on the same side of the two sets of wheelsets; the two baffles 140 located on the same side of the two sets of wheelsets are located in the same plane. Since the two baffles 140 located in the same plane are equidistant from the centerline of the track, the inner distance of the two sets of wheelsets is thus guaranteed to be equal. In other words, the device can use the platform 110 to limit the parallelism and flatness of the track 130, and meet the requirement that the two baffles 140 are on the same plane and parallel to the track 130. Thus, by limiting the flatness of the two baffles 140 on the same plane, the inner distance of the two sets of wheelsets can be reliably limited. During the hoisting of the wheelset axle box assembly, the two sets of wheelsets are placed close to the baffles 140 on the same side, thus ensuring that when the inner sides of the two sets of wheelsets are placed on the track 130, they can ultimately achieve the purpose of being on the same plane. This ensures that when the frame is lowered into the wheelset axle box assembly, each component can be correctly embedded, improving the completion accuracy and work efficiency.

[0046] For example, such as Figure 2As shown, the preferred baffle 140 includes a connecting plate and a positioning plate. The connecting plate is placed flat on the lowering platform 110. The positioning plate is connected to the side of the connecting plate closest to the corresponding side of the rail body. The connecting plate and the positioning plate are angled, with the side of the positioning plate facing the rail body always aligned with the vehicle height direction, used for calibrating and positioning the inner surface of the wheelset's inner rim. The connecting plate is fixed to the lowering platform 110 with bolts, serving to fix and support the baffle 140. To facilitate adjustment of the distance between different baffles 140 and the inner surface of the rail body, the preferred connecting plate is provided with several elongated holes, the length of which is aligned with the vehicle width direction. The preferred distance between the baffle 140 and the inner surface of the rail body is the distance between the inner surface of the wheelset's rim and the 70mm centerline of the wheelset tread.

[0047] In some specific embodiments, such as Figure 2 and Figure 3 As shown, multiple placement support mechanisms 120 are arranged in pairs on the placement platform 110 along both sides of the track 130. The axle boxes at both ends of each wheelset are supported by a pair of placement support mechanisms 120 through positioning nodes. The placement support mechanism 120 is used to support and adjust the height of the axle box composed of the wheelset axle box. It can reliably adjust the height of the axle box by adjusting and supporting the height of the positioning nodes of the swing arm, ensuring that the upper accessories of the axle box are horizontally set relative to the reference plane (i.e., the assembly plane), and improve the placement versatility for various types of bogies by adjusting the height of the axle box.

[0048] For example, such as Figure 3 As shown, the preferred bogie support mechanism 120 includes a first support base 1201, a second support base 1202, a lifting drive assembly, and a limiting assembly. The first support base 1201 is adapted to support the bottom of the positioning node of the corresponding axle box, and is used to contact and support the swing arm height of the axle box. The second support base 1202 is disposed on the bogie platform 110. The lifting drive assembly is connected between the first support base 1201 and the second support base 1202. The lifting drive assembly is used to drive the relative lifting between the first support base 1201 and the second support base 1202, thereby adjusting the height positioning of the swing arm to ensure that the swing arm heights of the four axle box bodies of the bogie are all on the same assembly plane, realizing reliable positioning of the two sets of wheelset axle box assemblies during the bogie assembly stage, ensuring that the assembled bogie can form a rectangular structure at the frame height, and achieving high-quality bogie assembly. The limiting assembly is connected between the first support base 1201 and the second support base 1202. The limiting component is used to limit the relative lifting and lowering of the first support 1201 and the second support 1202, that is, to provide bidirectional guidance for the relative lifting and lowering of the first support 1201 and the second support 1202, so as to improve the accuracy of the swing arm height adjustment.

[0049] For example, such as Figure 3As shown, the preferred lifting drive assembly includes a drive rod 1209, a drive bevel gear 1206, a transmission bevel gear 1205, and a lifting screw 1204. The drive rod 1209 is connected to the first support base 1201 via a bearing portion 1210. During the rotation of the drive rod 1209, the bearing portion 1210 can both bear the driving load, ensuring reliable power transmission for the lifting drive, and ensure smooth rotation of the drive rod 1209. Furthermore, the bearing portion 1210 is positioned and connected to the first support base 1201, allowing the lifting drive assembly to reliably move the first support base 1201 relative to the second support base 1202. The drive bevel gear 1206 passes through the drive rod 1209, and the transmission bevel gear 1205 meshes with the drive bevel gear 1206 at an angle. The meshing connection of the drive bevel gear 1206 and the transmission bevel gear 1205 forms a gear transmission pair. Preferably, the rotation shaft of the transmission bevel gear 1205 is arranged along the vehicle height direction. This allows the drive bevel gear 1206 and the transmission bevel gear 1205 to be connected at an angle, enabling the rotation of the drive rod 1209 at any angle to be transmitted to the transmission bevel gear 1205 via the drive bevel gear 1206, reliably changing the direction of force transmission. One end of the lifting screw 1204 passes through the transmission bevel gear 1205, and the other end is connected to the second support base 1202. The lifting screw 1204 can rise and fall relative to the second support base 1202 while rotating. Thus, by changing the direction of the rotational driving force, the rotational power of the horizontally positioned drive rod 1209 is converted into the rotational power of the lifting screw 1204 along the vehicle height direction, ensuring that the relative movement direction between the first support base 1201 and the second support base 1202 is sufficiently accurate, reliable, and effortless. Furthermore, the combination of the angled transmission of the bevel gear and the spiral lifting structure of the lifting screw 1204 enables the lifting drive assembly to have a double locking capability, thereby improving the lifting safety and stability of the support mechanism 120.

[0050] For example, such as Figure 3As shown, the preferred first support base 1201 includes a first base body. A cavity is provided within the first base body, and a lifting drive assembly is disposed within the cavity. The second support base 1202 is at least partially inserted within the cavity, thereby forming a nested structure between the first support base 1201 and the second support base 1202. The second support base 1202 is connected to the first support base 1201 within the cavity of the first support base 1201 via the lifting drive assembly, thus utilizing the outer shell of the first base body and the second support base 1202 to form a primary motion limit, improving the reliability and stability of the lifting mechanism. More preferably, the drive rod 1209 of the lifting drive assembly is horizontally positioned at the top of the cavity of the first base body, generating a horizontal driving force through rotation. Correspondingly, the drive bevel gear 1206 is vertically inserted into the drive rod 1209, and the rotation center of the drive bevel gear 1206 is the axis of the drive rod 1209, i.e., the horizontal direction. The transmission bevel gear 1205 meshes with the drive bevel gear 1206 in the horizontal direction, thus the drive bevel gear 1206 and the transmission bevel gear 1205 are set at right angles, thereby converting the horizontal driving force into the vertical driving force. The side wall of the first body is fitted with the outer sleeve of the bearing part 1210. One end of the drive rod 1209 is connected to the shaft hole of the bearing seat 1208, and the other end of the drive rod 1209 is inserted into the other side wall of the first body opposite to the bearing part 1210 and connected to the rotating wheel 1213. The lifting control can be achieved by manually rotating the rotating wheel 1213.

[0051] Understandably, the drive rod 1209 can also be directly connected to a drive mechanism, such as a drive motor.

[0052] For example, such as Figure 3 As shown, the preferred first support 1201 further includes a support platform 1207 and a bearing housing 1208. The support platform 1207 is disposed on the top of the first support body and is used to contact and support the bottom of the positioning node of the axle box. Preferably, the support platform 1207 is located at the geometric center of the top of the first support body to improve the stability and reliability of the supporting force. The bearing housing 1208 connects the support platform 1207 and the first support body. A thrust bearing is assembled inside the bearing housing 1208. The thrust bearing can reliably bear axial force, improving the load-bearing capacity of the first support 1201 on the axle box.

[0053] For example, such as Figure 3 As shown, the preferred second support 1202 includes a base 1203 and a second body. The base 1203 is fixed to the platform 110. The bottom of the second body is connected to the base 1203. The second body at least partially passes through the cavity of the first body. The base 1203 can increase the contact area of ​​the second support 1202 on the platform 110, thereby improving the pressure-bearing capacity of the second support 1202.

[0054] For example, the preferred limiting component includes a limiting groove 1212 and a limiting block 1211. The limiting groove 1212 is disposed vertically along the bogie in one of the first support 1201 and the second support 1202; the limiting block 1211 is disposed in the other of the first support 1201 and the second support 1202, and the limiting block 1211 is slidably assembled within the limiting groove 1212. By utilizing the reliable assembly and limiting of the limiting groove 1212 and the limiting block 1211, the lifting direction of the first support 1201 and the second support 1202 can be more reliably and accurately limited, ensuring more precise and reliable guidance for the relative lifting of the first support 1201 and the second support 1202.

[0055] In this embodiment, as Figure 3 As shown, the cross-sectional structure of the preferred limiting groove 1212 and the limiting block 1211 is V-shaped, thereby further improving the limiting stability. To ensure more reliable relative sliding between the limiting groove 1212 and the limiting block 1211, a bottom plane can be added to the bottom of the V-shaped cross-section, thereby making the cross-sections of the limiting groove 1212 and the limiting block 1211 trapezoidal. Specifically, in this embodiment, the limiting block 1211 is preferably formed on the inner surface of the first support 1201 and on the outer surface of the second support 1202, thereby reducing the processing difficulty of the limiting groove 1212 and the limiting block 1211.

[0056] The following is for reference Figures 4 to 7 The adjustment platform 200 described in the embodiment of the present invention will be described in detail.

[0057] In some embodiments, such as Figure 4 As shown, the preferred adjustment platform 200 includes an adjustment platform 210, multiple adjustment support mechanisms 220, and the aforementioned bidirectional locking mechanism 230. To ensure accurate bogie dimensional inspection and avoid inspection errors and rework, during the bogie assembly process, the adjustment platform 200, through the adjustment platform 210, provides a base plane for subsequent adjustments and inspections of the bogie after the assembly stage. The multiple adjustment support mechanisms 220 provide reliable support for the corresponding axle boxes on the two sets of wheelsets of the bogie, thereby placing the entire bogie in a suspended state. The bidirectional locking mechanism 230 is used to lock the wheelsets, ensuring that the wheelsets are stationary.

[0058] In some specific embodiments, such as Figure 4As shown, multiple adjustment support mechanisms 220 are arranged in pairs on the adjustment platform 210. Each wheelset's two ends are supported by a pair of adjustment support mechanisms 220 via axle box bodies. A bidirectional locking mechanism 230 is provided between each pair of adjustment support mechanisms 220. Thus, this device, through the reliable support of the axle box bodies by the adjustment support mechanisms 220, enables the bogie to stably hover off the ground during the adjustment and testing phase, thereby achieving high-precision and stable testing of the bogie's inner wheelset distance, diagonal, and wheelbase dimensions after the bogie's completion phase.

[0059] Understandably, to ensure the accuracy of bogie dimensional inspection, the device in this embodiment uses the horizontal position of each component of the wheelset and frame as the inspection benchmark. This ensures that the assembly relationship of each component is not affected and avoids dimensional measurement errors caused by assembly. Therefore, the device in this embodiment selects the lower part of the axle box as the support point, supporting the wheelset bearings and upper components of the axle box to ultimately achieve overall bogie lifting. Consequently, the adjustment support mechanism 220 in this embodiment places the bogie adjustment platform 200 support mechanism at the lower part of the axle box.

[0060] For example, such as Figure 4 As shown, preferably, four sets of adjustment support mechanisms 220 are respectively set below the corresponding axle box on the outer side of the track 130, and the four sets of adjustment support mechanisms 220 are set in pairs corresponding to the positions of the two sets of wheelsets. Since the top height of each set of adjustment support mechanisms 220 is located on the same adjustment plane, the four-point equal height dimension adjustment method can be fully utilized to achieve the stable suspension of the bogie during the adjustment and inspection process, thereby stabilizing the stability of dimension inspection and reducing the rework rate of bogie dimension inspection.

[0061] Understandably, the four-point equal-height dimensional adjustment method described in this embodiment refers to the following: To achieve stability in bogie dimensional inspection, during bogie dimensional adjustment and inspection (i.e., the adjustment and inspection phase), four sets of adjustment support mechanisms 220 are used to coordinate the entire bogie on the same adjustment plane. Through comparison, the lower part of the axle box is selected as the support position, suspending the bogie in the air, and ensuring that the height of the four support points is less than or equal to 0.02mm, thus ensuring equal height at the four points. The four-point equal-height dimensional adjustment method can further improve the stability of bogie dimensional inspection and reduce the rework rate of bogie dimensional inspection.

[0062] For example, such as Figure 4 , Figure 5 and Figure 6As shown, preferably each adjustment support mechanism 220 has a sliding amount at least in the axle length direction of the wheelset. Thus, the pair of adjustment support mechanisms 220 can flexibly adjust the spacing of each pair of adjustment support mechanisms 220 in the vehicle width direction to flexibly adapt to bogies with different wheelbases and different inner distances of wheelsets, thus expanding the versatility of this device.

[0063] In some specific embodiments, such as Figure 7 As shown, the bidirectional locking mechanism 230 includes an adjusting wheel 2303, two push rods 2304, and two clamping parts 2306. The adjusting wheel 2303 is used to uniformly control the rotation of the push rods 2304, thereby controlling the clamping state and position of the clamping parts 2306 on the inner side of the wheelset body. One end of each push rod 2304 is connected to the adjusting wheel 2303. The other end of each push rod 2304 is respectively equipped with a clamping part 2306. The adjusting wheel 2303 is used to synchronously drive the two push rods 2304 to rotate in opposite directions, so that the two clamping parts 2306 can be synchronously locked and fixed to the inner side of the two wheelsets. Thus, the bidirectional locking mechanism 230, based on the above structure, can reliably lock the wheelset during the adjustment and inspection stage, especially during the dimensional inspection process, preventing the wheelset from rotating, and can also play a role in fixing the wheelset during the torque engraving process of the rotating components above the wheelset. The bidirectional locking mechanism 230 is placed between the two wheels of the wheelset during use, and ultimately achieves the locking function of the wheelset.

[0064] For example, such as Figure 7 As shown, preferably, the two push rods 2304 are provided with opposite rotation directions, thereby realizing the synchronous drive of the single wheel to the reverse movement of the two rods, and finally realizing the synchronous extension and retraction of the two clamping parts 2306 relative to the two connected push rods 2304, so that the clamping parts 2306 can synchronously clamp against the inner side of the two wheel bodies of the wheelset, stopping and restricting the rotation of the wheelset.

[0065] Understandable, such as Figure 4 In this embodiment, the adjustment platform 210 is equipped with two sets of bidirectional locking mechanisms 230 at the front and rear ends of the two sets of wheelsets on the bogie, respectively, so as to reliably lock the two sets of wheelsets. All push rods 2304 of the two sets of bidirectional locking mechanisms 230 are set parallel to the axle, that is, along the vehicle width direction, so as to lock the wheelsets at the angle with the least effort.

[0066] For example, such as Figure 7As shown, preferably, one end of the push rod 2304 is fixed to the rotating shaft of the adjusting wheel 2303, and the rotation of the adjusting wheel 2303 drives the push rod 2304 to rotate. Preferably, two push rods 2304 are respectively connected to both ends of the rotating shaft of the adjusting wheel 2303, thereby ensuring that both push rods 2304 can rotate with the rotation of the adjusting wheel 2303. The other end of the push rod 2304 is rotatably fitted into the threaded hole of the tightening part 2306 through the threaded part 2305. Preferably, the threaded part 2305 of one of the two push rods 2304 is connected to the corresponding tightening part 2306 through a left-hand thread, and the threaded part 2305 of the other push rod is connected to the corresponding tightening part 2306 through a right-hand thread, ensuring that the rotation of the adjusting wheel 2303 drives the two push rods 2304 to rotate in opposite directions. The end face of the tightening part 2306 facing away from the push rod 2304 is provided with a pushing plane to improve the locking force of the tightening part 2306 on the wheelset and increase the friction.

[0067] For example, such as Figure 7 As shown, the bidirectional locking mechanism 230 also includes a reference base 2301 and two sets of locking support seats 2302. The reference base 2301 is mounted on the adjustment platform 210. The adjusting wheel 2303 is mounted on the reference base 2301. The two sets of locking support seats 2302 are respectively located on both sides of the reference base 2301. Each set of locking support seats 2302 is equipped with a tightening part 2306. The two sets of locking support seats 2302 are used to support the two tightening parts 2306 respectively.

[0068] For example, such as Figure 7 As shown, the tightening part 2306 passes through the top of the locking support 2302, and its height is consistent with the axis of the push rod 2304. To ensure that the tightening part 2306 can move linearly in the top shaft hole of the locking support 2302, it is preferable that the tightening part 2306 and the top shaft hole of the locking support 2302 are assembled by a flat key 2307. When the adjusting wheel 2303 is rotated, it drives the two push rods 2304 to rotate in opposite directions, and through the threaded parts 2305 with different directions of rotation at the ends of the two push rods 2304, the two tightening parts 2306 are finally synchronized in the shaft holes of the two locking support 2302, thereby ensuring that the two tightening parts 2306 are more reliably supported on the basis of synchronously locking the two wheels of the wheelset.

[0069] Understandably, the reference seat 2301 can be preferably positioned at any location between the two wheels of the wheelset, and the synchronous locking of the two wheels of the wheelset can be achieved simply by changing the lengths of the two push rods 2304. However, the reference seat 2301 is preferably located on the center line of the bogie width, so as to ensure that the locking force of the reference seat 2301 on both sides of the clamping parts 2306 is more balanced and stable.

[0070] In some specific embodiments, such as Figure 5 and Figure 6 As shown, the preferred adjustment support mechanism 220 includes a support column 2204 and multiple sets of sliding pairs. A detection assembly is mounted on the support column 2204, which is used for precise measurement, dimensional inspection, no-load testing, and performance verification of the bogie during the adjustment and inspection phase. The sliding pairs are connected via the support column 2204. One set of sliding pairs is located on the adjustment platform 210, serving to position the adjustment support mechanism 220 relative to the adjustment platform 210; another set of sliding pairs connects to the axle box, ensuring a reliable connection between the adjustment support mechanism 220 and the axle box. The sliding pairs are angled relative to each other, and at least one set of sliding pairs has a sliding amount in the axle length direction of the wheelset. Therefore, based on the above structure, the adjustment support mechanism 220 can flexibly adjust the specific position of the support column 2204 relative to the axle box in the vehicle width direction. The axle box receives axially stable support from the support column 2204, thus allowing each pair of adjustment support mechanisms 220 to flexibly adapt to bogies with different wheelbases and different wheelset inner distances.

[0071] For example, such as Figure 5 and Figure 6 As shown, the preferred sliding pair includes a slider seat and a sliding groove. The slider seat is provided with a slide rail. At least one end of the slide rail is provided with a limiting plate. The sliding groove is assembled to the slider seat and can slide along the slide rail. One of the slider seat and the sliding groove is connected to a support column 2204. The sliding groove is slidably connected to the slider seat, thereby allowing the support column 2204 to flexibly adjust its position relative to the slide rail, thus more flexibly adapting to the axle box body. The limiting plate is used to stop and limit the sliding of the slider seat, preventing the slider seat from derailing.

[0072] For example, such as Figure 4 As shown, in the adjustment support mechanism 220 of this embodiment, two sets of sliding pairs are respectively connected to both ends of the support column 2204. One set of sliding pairs is disposed on the adjustment platform 210, and the other set of sliding pairs is connected to the axle housing. The two sets of sliding pairs are arranged at an angle, and at least one set of sliding pairs has a sliding amount in the axle length direction of the wheelset. This structure is the simplest and most reliable. (Refer to...) Figure 5 and Figure 6As shown, one set of slider pairs includes a first slider seat 2201 and a first slide groove 2203. The first slider seat 2201 is fixed to the adjustment platform 210 by bolts, and the slide rail of the first slider seat 2201 is arranged along the vehicle width direction. The first slide groove 2203 is slidably assembled to the first slider seat 2201. The first slider seat 2201 is connected to the bottom end of the support column 2204. First limiting plates 2202 are respectively provided at both ends of the slide rail of the first slider seat 2201. Another set of slider pairs includes a second slider seat 2205 and a second slide groove 2206. The second slider seat 2205 is connected to the top end of the support column 2204, and the slide rail of the second slider seat 2205 is arranged along the vehicle length direction. The second slide groove 2206 is slidably assembled to the second slider seat 2205. A bearing body is supported on the second slide groove 2206. Second limiting plates 2207 are respectively provided at both ends of the slide rail of the second slider seat 2205. This configuration allows the adjustment support mechanism 220 to be adjusted in both the width and length directions. The second slide groove 2206 serves as the direct contact point with the axle box, employing sliding support to achieve adjustment support for different wheelbases. Preferably, the second slide groove 2206 is a tapered structure. When the bidirectional locking mechanism 230 secures the locking wheel pair axle box assembly, the adjustment support mechanism 220 utilizes the tapered second slide groove 2206 to ensure the lower part of the axle box fits closely with the bogie, achieving a four-point outward support for the bogie above the four sets of adjustment support mechanisms 220, thus stabilizing the bogie's support structure. Preferably, the second slider seat 2205 and the support column 2204 are connected using a T-shaped structure. The support column 2204 is connected to the first slide groove 2203 via the lower T-shaped structure, ultimately enabling adjustment of the adjustment support mechanism 220 in four directions: front-back, left-right, and right-right.

[0073] For example, such as Figure 5 and Figure 6 As shown, the preferred detection component includes a mounting base 2208. The mounting base 2208 is mounted on a support column 2204. The mounting base 2208 is provided with a measuring mounting section 2209 and / or a detection mounting section 2210. The measuring mounting section 2209 is used to mount a measuring instrument, as shown in the reference diagram. Figure 5 As shown; the detection mounting section 2210 is used to mount the detection board, see reference. Figure 6 As shown. The measuring instrument and inspection plate can be flexibly replaced or simultaneously installed according to inspection needs, enabling precise adjustment and dimensional inspection of the wheelbase and inner distance of the wheelset. This configuration improves the inspection accuracy of the device in this embodiment from the original visual adjustment method to an accuracy control of 0.01mm. Furthermore, through the dual cooperation of the measuring mounting part 2209 and the inspection mounting part 2210, the device can achieve precise positioning of the wheelbase and inner distance support for different types of bogies, improving the accuracy adjustment to 0.005mm compared to the original manual adjustment method during bogie assembly.

[0074] The bogie assembly and adjustment method according to an embodiment of the present invention will be described in detail below. The bogie assembly and adjustment method described in this embodiment is performed using the bogie assembly and adjustment device described above. Therefore, the specific operation flow of the method in this embodiment is basically the same as the usage process of the device described above. Parts not mentioned in the following method can be referred to in the specific description of the device described above.

[0075] The bogie commissioning and adjustment method in this embodiment includes a commissioning stage and an adjustment and testing stage.

[0076] For example, the completion stage includes the following operation process: using the completion platform 100 to perform relative positioning of the two sets of wheelsets of the bogie, and to perform height positioning and support on the positioning nodes of the axle box body so that the positioning nodes of each axle box body are on the same assembly plane, thereby completing the positioning and assembly of the two sets of wheelset axle box assemblies; and to perform the completion and assembly of the frame on the two sets of wheelset axle box assemblies after the assembly is completed.

[0077] For example, the adjustment and testing phase includes the following operation process: adjusting the adjustment platform 200 based on the wheelbase of the bogie; using the adjustment platform 200 to suspend the completed bogie, and using the aforementioned bidirectional locking mechanism 230 to lock the wheels of the wheelset to a stationary state; and testing the bogie on the adjustment platform 200.

[0078] Therefore, the device and method described in this embodiment are based on an analysis of the current operational status of the bogie assembly process for railcar 130, aiming to improve the quality and efficiency of bogie assembly and meet the final usage requirements of each bogie component. In the device and method of this embodiment, during the assembly stage, two baffles 140 located on the same plane are used to achieve relative positioning of the two sets of wheelsets of the bogie, and the assembly support mechanism 120 is used to achieve height positioning and support of the positioning nodes of the axle box, so that the positioning nodes of each axle box are all on the same assembly plane, thereby realizing the rapid assembly and construction of the wheelset axle box composition and frame, while ensuring that the two axles of the bogie always maintain a rectangular structure, avoiding the collision and impact of components. During the adjustment and testing phase, the wheelset is reliably stationary by utilizing the cooperation of the bidirectional locking mechanism 230 and the adjustment support mechanism 220. Based on the four-point equal height dimension adjustment method, the bogie is adjusted and tested, and the bogie is made universally compatible with different inner distances of wheelsets and different wheelbases. Furthermore, the implementation of the four-point equal height dimension adjustment method further improves the accuracy of bogie dimension testing and enhances the stability of bogie operation.
