Description

Technical Field

[0001] This utility model relates to the field of locomotive maintenance technology, and in particular to a machine tool device for maintaining bogies. Background Technology

[0002] A bogie is a key component located at the bottom of a vehicle (such as a railway locomotive, passenger car, freight car, and urban rail transit vehicle). It is an independent running gear, usually consisting of front and rear wheels. Since wheels are prone to wear during operation, wheel maintenance is an essential part of routine upkeep.

[0003] When maintaining existing bogie wheels, the bogie is placed into the machine tool's working area in a certain way, the wheels are positioned or clamped, and the front and rear wheels are rotated by the drive device. Then, under the control of the CNC system, the cutting tool cuts the wheel tread and flange according to the preset machining parameters (such as depth, feed rate, etc.). Since the front and rear wheels are connected by a drive shaft, when one wheel rotates, it will drive the other wheel to rotate through the drive shaft. If the other wheel, which does not need to be cut, rotates unexpectedly on the track, it may cause the entire vehicle to shake or shift, making it impossible to process the other wheel normally. Therefore, when processing the front and rear wheels, the operator can only remove the drive shaft between the front and rear wheels. The disassembly and assembly of the drive shaft is inconvenient and time-consuming. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a machine tool device for maintaining bogies, which can complete the maintenance of the front and rear wheels on the bogies without removing the drive shaft, making disassembly and assembly convenient and easy to maintain.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A machine tool device for maintaining a bogie, comprising:

[0007] A base, on both sides of which are equipped with guide rails for guiding the rolling of the bogie;

[0008] The lifting mechanism includes at least two lifting mechanisms, each pair of which are arranged opposite to each other and located on the sides of the two guide rails respectively. The lifting mechanism includes a lifting member and a lifting drive member. The lifting member is movably connected to the base and can move up and down along the Z-axis. The lifting drive member is used to drive the lifting member to move up and down along the Z-axis. The lifting drive member is used to lift the bogie when moving upward along the Z-axis.

[0009] Furthermore, the lifting mechanism includes a mounting base and a mounting base drive component. The mounting base is movably connected to the machine base and can move up and down along the Z-axis. The lifting component is mounted on the mounting base. The lifting drive component is used to drive the mounting base to move up and down along the Z-axis. The mounting base drive component is used to drive the mounting base to move along the Y-axis.

[0010] Furthermore, the mounting base is provided with a pushing mechanism, which includes a pushing component and a pushing drive component. The pushing component includes a pushing seat, which is movably mounted on the mounting base and used to mount the lifting component. The pushing seat can move along the Y-axis direction to drive the lifting component to move along the Y-axis direction. The pushing drive component is used to drive the pushing seat to move along the Y-axis direction.

[0011] Furthermore, the pusher includes a push rod, one end of which is connected to the push seat, and the other end of which is connected to the push drive.

[0012] Furthermore, the pusher seat is provided with a movable bracket, the lifting member is installed on the movable bracket, the lifting drive member is connected to the movable bracket, and is used to drive the movable bracket to move along the Z-axis direction after the pusher seat moves along the Y-axis direction, so that the lifting member moves along the Z-axis direction.

[0013] Furthermore, the mounting base is also provided with a support mechanism, which includes a support member and a support member drive member. The support member can move closer to or away from the movable bracket along the X-axis direction, and is used to extend into the bottom of the movable bracket after moving closer to the movable bracket to support the movable bracket.

[0014] Furthermore, the support member includes a support rod arranged along the X-axis direction, and the support member drive member is used to drive the support rod to move in the X-axis direction. The support rod is used to extend into the bottom of the movable bracket after moving close to the movable bracket in the X-axis direction.

[0015] Furthermore, a support plate is provided at one end of the support rod near the movable bracket. The support plate includes a first plate segment and a second plate segment. The first plate segment is used to extend into the bottom of the movable bracket after the support plate moves close to the movable bracket. The second plate segment is arranged perpendicularly to the first plate segment and is used to abut against the outer periphery of the movable bracket after the first plate segment extends into the bottom of the movable bracket.

[0016] Furthermore, there are at least four lifting mechanisms, and each of the mounting bases is equipped with a pushing mechanism.

[0017] Furthermore, the lifting member includes at least two rollers, which are used to abut against the wheel surface of the bogie when moving upward along the Z-axis direction.

[0018] In summary, the machine tool device for maintaining bogies provided by this utility model has the following technical effects: after the bogie rolls to the designated position on the machine base along the guide rail, when maintenance of the front or rear wheel is required, the lifting drive component is simply used to drive the lifting component to move upward along the Z-axis to lift the wheel that does not need maintenance and remove it from the guide rail. In this way, even if the wheel that does not need maintenance rotates normally under the drive of the drive shaft, it will not cause the bogie to shake or shift due to its own rotation because it is in a suspended state, thus not interfering with the processing of the other wheel. Therefore, the operator does not need to remove the drive shaft during the maintenance process, making the operation simple, time-saving and labor-saving. Attached Figure Description

[0025] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] See Figures 1 to 4 This utility model discloses a machine tool device for maintaining a bogie, including a machine base 10 and a lifting mechanism 20. Guide rails 11 are installed on both sides of the machine base 10 to guide the rolling of the bogie. There are at least two lifting mechanisms 20, which are arranged opposite to each other and located on the sides of the two guide rails 11 respectively. The lifting mechanism 20 includes a lifting member 21 and a lifting drive member 23. The lifting member 21 is movably connected to the machine base 10 and can move up and down along the Z-axis. The lifting drive member 23 is used to drive the lifting member 21 to move up and down along the Z-axis. The lifting drive member 23 is used to lift the bogie when moving upward along the Z-axis.

[0029] Based on the above structure, taking the Z-axis direction as the height direction of the base 10 as an example, during assembly, each pair of lifting mechanisms 20 is set near the side of the guide rail 11 and is set on the two guide rails respectively. When each pair of lifting members 21 is driven by the lifting drive member 23 to move upward along the Z-axis direction (that is, the height direction of the base 10), it lifts the bogie, so that the wheels on the bogie can be removed from the rail.

[0030] Specifically, taking the grinding of the front wheels of the bogie as an example, the bogie is first rolled with the bottom wheels of the bogie and the guide rail 11 to move the bogie to the processing area of ​​the machine base 10. Specifically, the bogie can be rolled until the rear wheels are aligned with the lifting mechanism 20. Then the bogie is clamped. At this time, the two lifting drive members 23 on the side of the two guide rails 11 drive the two lifting members 21 to lift the two rear wheels of the bogie upward along the Z-axis, so that the rear wheels are disengaged from the guide rails 11 and are suspended in the air. Then, the front wheels on the guide rails 11 are rotated by the drive device on the machine tool or the power source of the bogie itself and ground. Since the rear wheels are disengaged from the guide rails 11, even when the front wheels rotate, the rear wheels are rotated by the drive shaft, and the rear wheels are rotated freely in the air and will not cause the bogie to roll and be displaced. This allows the bogie to always be locked in the processing area so that the front wheels can be ground normally while rotating.

[0031] Similarly, when the rear wheels need to be ground, the two front wheels are simply lifted by the two lifting members 21, so that the front wheels are suspended and rotate in the air. In this way, the bogie will not be displaced along the guide rail 11 due to simultaneous rotation with the rear wheels, allowing the rear wheels to be ground normally. Therefore, when using the machine tool device for user maintenance of the bogie in this embodiment, since the other wheel that does not need to be ground can be lifted by the lifting member 21 when either the front or rear wheel is being repaired, even if the front and rear wheels rotate synchronously under the drive of the drive shaft, the bogie will not be displaced, allowing the grinding operation to be carried out normally. Therefore, it is not necessary to remove the drive shaft connecting the front and rear wheels, and one wheel can be ground normally, making the maintenance process faster, saving time and effort.

[0032] It should be noted that the lifting drive component 23 in this embodiment can be selected from existing cylinder drive, hydraulic drive, or drive motor. When cylinder drive or hydraulic drive is used, the lifting component 21 is connected to the piston rod of the cylinder body so that the lifting component 21 can move up and down along the Z-axis by the reciprocating movement of the piston rod. When the lifting drive component 23 is a drive motor, the motor shaft of the drive motor can be connected to the lifting component 21 so that the lifting component 21 can move up and down along the Z-axis by the rotation of the motor shaft.

[0033] In addition, the lifting mechanism 20 is set in an even number, specifically two, four, six or more. Each pair of lifting mechanisms 20 is set on two guide rails so that each pair of lifting members 21 can lift a pair of wheels at the same time, which is convenient for maintenance. Specifically, the lifting member 21 can be a block, plate or rolling wheel structure to abut against the bogie. When a plate or block structure is used, the lifting member 21 can abut against the end face of the bogie near the wheel after the bogie moves close to the bogie, so that the bogie can rotate normally after being lifted, and will not jam due to contact with the lifting member 21, causing the other wheel being maintained to jam as well. When the lifting member 21 is a rolling wheel, the lifting member 21 can directly abut against the wheel when it moves upward along the Z-axis. In this way, the rolling wheel will also rotate after the wheel is lifted, without interfering with the normal rotation of the wheel.

[0034] Preferably, the lifting member 21 in this embodiment includes at least two rollers, which are used to abut against the wheel surface of the bogie when moving upward along the Z-axis.

[0035] When the lifting component 21 uses at least two rollers to abut against the wheel surface of the upper wheel of the bogie and moves upward, the rolling contact method of the rollers can significantly reduce the contact friction. Compared with the planar contact lifting method, the rollers and the wheel surface have rolling friction. After the wheel is lifted by the rollers, the wheel is not likely to be unable to rotate due to excessive friction. This avoids the phenomenon that when one wheel is lifted, the other wheel connected to it cannot rotate normally.

[0036] Meanwhile, since the lifting member 21 includes at least two rollers, the contact area between the lifting member 21 and the wheel is increased by the at least two rollers, so that the wheel is supported more stably by the at least two rollers. The specific number of rollers can be designed to be three, four or more depending on the size of the wheel on the bogie.

[0037] Furthermore, the lifting mechanism 20 includes a mounting base 22 and a mounting base drive. The mounting base 22 is movably connected to the base 10 and can move up and down along the Z-axis. The lifting member 21 is mounted on the mounting base 22. The lifting drive 23 is used to drive the mounting base 22 to move up and down along the Z-axis. The mounting base drive is used to drive the mounting base 22 to move along the Y-axis.

[0038] Specifically, in this embodiment, the lifting member 21 can be installed on the mounting base 22 to make the structure more stable. Then, by connecting the mounting base 22 to the power output end of the lifting drive member 23, the lifting drive member 23 can directly drive the mounting base 22 to move along the Z-axis direction, thereby driving the lifting member 21 to move along the Z-axis direction. Alternatively, the mounting base 22 can be slidably installed on the machine base 10, and the lifting drive member 23 can drive the mounting base 22 to slide along the Z-axis direction, thereby driving the lifting member 21 to move in the Z-axis direction.

[0039] More specifically, since the mounting base drive can also drive the mounting base 22 to move along the Y-axis, if the lifting member 21 is not aligned with the wheel position of the bogie in the horizontal direction after the mounting base 22 moves along the Z-axis, the mounting base drive can drive the mounting base 22 to drive the lifting member 21 to move along the Y-axis, so that the lifting member 21 can move more accurately to the designated position and more easily lift the bogie or wheel.

[0040] It should be noted that the Y-axis direction can be the length direction of the base 10. When the mounting base 22 can move along the Y-axis direction, during assembly, the mounting base 22 can be movably mounted on a movable plate that can move along the Z-axis on the base, and can move along the Y-axis direction. The lifting drive 23 is connected to the movable plate to drive the movable plate up and down along the Z-axis direction, thereby driving the mounting base 22 and the lifting member 21 on the mounting base 22 to move along the Z-axis direction. The mounting base drive can be mounted on the movable plate and directly connected to the mounting base 22 to drive the mounting base 22 to move along the Y-axis direction. In this way, the mounting base 22 and the lifting member 21 can be driven to move along the Z-axis direction by the lifting member drive 23. At the same time, the mounting base drive can also drive the mounting base 22 and the lifting member 21 to move along the Y-axis direction, so that the lifting member 21 can be adjusted in multiple dimensions to more accurately lift the bogie. Specifically, the mounting base drive can be an existing cylinder drive, hydraulic drive, or drive motor.

[0041] Furthermore, the mounting base 22 is provided with a pushing mechanism, which includes a pushing component and a pushing drive component 32. The pushing component includes a pushing seat 31, which is movably mounted on the mounting base 22 and used to mount the lifting component 21. The pushing seat 31 can move along the Y-axis direction to drive the lifting component 21 to move along the Y-axis direction. The pushing drive component 32 is used to drive the pushing seat 31 to move along the Y-axis direction.

[0042] Specifically, the lifting component 21 is installed on the pusher seat 31, and then the pusher seat 31 is movably installed on the mounting seat 22, specifically, it can be slidably connected to the mounting seat 22. Thus, when the mounting seat 22 moves along the Z-axis, the pusher seat 31 also moves along the Z-axis, so that the lifting component 21 located on the pusher seat 31 moves along the Z-axis. When the lifting component 21 moves along the Z-axis, there is a deviation in the Y-axis direction ((the length direction of the base 10)), and it cannot lift the bogie or the wheel. At this time, the pusher drive component 32 drives the pusher seat 31 to move along the Y-axis, thereby driving the lifting component 21 installed on the pusher seat 31 to move in the Y-axis direction, so as to adjust the position of the lifting component 21 in the Y-axis direction.

[0043] It should be noted that the push drive component 32 can be a drive cylinder, a hydraulic drive, or a drive motor, etc. The drive rod (such as a piston rod or a motor shaft) of the push drive component 32 is set along the Y-axis and connected to the push seat 31 to drive the push seat 31 to move along the Y-axis. Alternatively, the piston rod of the push drive component 32 can be connected to the push seat 31 through a connecting rod, a transmission shaft, or a push block, etc., which can achieve the same effect.

[0044] More specifically, in this embodiment, the pusher includes a push rod 33. During assembly, the push rod 33 is set along the Y-axis direction, and one end of the push rod 33 is connected to the push seat 31, while the other end of the push rod 33 is connected to the push drive 32. Thus, when the push drive 32 drives the push rod 33 to move along the Y-axis direction, it can simultaneously push the push seat 31 to move along the Y-axis direction.

[0045] Compared to directly connecting the push drive 32 to the push seat 31, the push rod 33 acts as a buffer between the push seat 31 and the push drive 32. When the movement speed of the push drive 32 changes suddenly or encounters resistance, the push rod 33 can absorb some of the impact force, reducing the risk of damage to the push seat 31 and the push drive 32 due to the impact force, and indirectly improving the service life of the structure.

[0046] Furthermore, the pusher seat 31 is provided with a movable bracket 34, the lifting member 21 is installed on the movable bracket 34, the lifting drive member 23 is connected to the movable bracket 34, and after the pusher seat 31 moves along the Y-axis direction, it drives the movable bracket 34 to move along the Z-axis direction, so that the lifting member 21 moves along the Z-axis direction.

[0047] Specifically, if the lifting component 21 is first raised along the Z-axis and then its position is adjusted along the Y-axis during use, its center of gravity will rise and its stability will decrease because the lifting component 21 is already at a high position. If a deviation occurs during adjustment along the Y-axis, the lifting component 21 may lose its balance, leading to equipment damage or even endangering the safety of the operator. Therefore, in this embodiment, a movable bracket 34 is set on the pusher seat 31, and the lifting component 21 is installed on the movable bracket 34. When the bogie 40 rolls to the designated position on the base 10, it can be first... The push drive 32 drives the push seat 31 to move along the Y-axis to adjust the position of the lifting member 21 in the Y-axis direction. After it is aligned with the wheel on the bogie 40, the lifting drive 23 drives the movable bracket 34 to move upward along the Z-axis until it touches the wheel, thereby lifting the wheel on the bogie 40. In this way, the position is adjusted when the lifting member 21 is not raised. Even if an operation error occurs, it will not cause serious safety accidents due to the height of the lifting member 21, such as the lifting member 21 tipping over, thus improving the safety during operation.

[0048] In addition, after the lifting component 21 is raised, the operating space around it will be somewhat restricted, which is not conducive to accurately adjusting the position in the Y-axis direction. This may make it difficult for the lifting component 21 to be accurately aligned with the wheel, increasing the difficulty and uncertainty of operation. Therefore, in this example, by adjusting the position of the lifting component 21 in the Y-axis direction first, the lifting component 21 can be more accurately aligned with the wheel on the bogie 40 before it is raised. In this case, the operator can clearly observe the relative position of the lifting component 21 and the wheel, avoiding collision between the lifting component 21 and the wheel during the raising process.

[0049] Furthermore, a support mechanism is provided on the mounting base 22. The support mechanism includes a support member and a support member drive member 35. The support member can move closer to or further away from the movable bracket 34 along the X-axis direction, and after moving closer to the movable bracket 34, it extends into the bottom of the movable bracket 34 to support the movable bracket 34.

[0050] Specifically, after the bogie 40 is lifted by the lifting member 21, the movable support 34 bears the weight of the bogie 40. It may sway due to uneven force distribution or external disturbances (such as vibration or minor impacts). Therefore, this embodiment includes a support mechanism. When the movable support 34 moves upward along the Z-axis, the support member can be driven by the support member drive 35 along the X-axis (e.g., ...). Figure 1 As shown in the figure, the pusher seat 31 moves closer to the bottom of the movable support 34 in the width direction until it abuts against the bottom of the movable support 34 to support the movable support 34. The support of the support can effectively reduce the sway of the movable support 34, making the bogie 40 more stable after being lifted, which facilitates the subsequent maintenance of the bogie 40.

[0051] It should be noted that the movable bracket 34 can be connected to the push seat 31 by a sliding connection. The support drive component 35 can also be an existing drive cylinder, hydraulic drive, or drive motor. The drive rod (such as a piston rod or motor shaft) of the support drive component 35 is set along the X-axis and connected to the support to drive the support to move along the X-axis. Alternatively, the drive rod of the support drive component 35 can be connected to the support through a connecting rod, transmission shaft, or push block, which can also achieve the above effect. The support can be a support rod 36 or a support plate 37 connected to the drive rod of the support drive component 35.

[0052] More specifically, the support member in this embodiment includes a support rod 36, which is set along the X-axis direction. The support rod 36 is driven to move along the X-axis direction by the support member drive member 35, so that after the support rod 36 moves close to the movable bracket 34 along the X-axis direction, it extends into the bottom of the movable bracket 34 to support the bottom of the movable bracket 34.

[0053] Furthermore, a support plate 37 is provided at one end of the support rod 36 near the movable bracket 34. The support plate 37 includes a first plate segment and a second plate segment. The first plate segment is used to extend into the bottom of the movable bracket 34 after the support plate 37 moves close to the movable bracket 34. The second plate segment is arranged perpendicular to the first plate segment and abuts against the outer periphery of the movable bracket 34 after the first plate segment extends into the bottom of the movable bracket 34.

[0054] Based on this structure, when the support rod 36 extends into the bottom of the movable bracket 34 along the X-axis direction for support, the movable bracket 34 may experience a certain lateral displacement when subjected to lateral forces (such as equipment vibration, slight collisions, etc.) due to the contact between the support rod 36 and the bottom of the movable bracket 34. However, the second plate segment is set perpendicular to the first plate segment and abuts against the outer periphery of the movable bracket 34, which can effectively limit the lateral movement of the movable bracket 34. For example, in a workshop environment, if other equipment or personnel accidentally touch the bogie 40 that has been lifted, the second plate segment can prevent the movable bracket 34 from shifting, ensuring that the bogie 40 is stably in the lifted state.

[0055] In addition, since the first plate segment extends into the bottom of the movable support 34 to provide the main upward support force, and the second plate segment abuts against the outer periphery of the movable support 34 to share some of the lateral force and torsional force, this multi-directional support method makes the distribution of support force more reasonable, can better cope with complex stress conditions, and further enhances the overall stability of the movable support 34 and the bogie 40.

[0056] Furthermore, in this embodiment, there are at least four lifting mechanisms 20. During assembly, at least four lifting mechanisms 20 are respectively installed on both sides of two guide rails 11. Every two lifting mechanisms 20 are arranged opposite each other and spaced apart. In addition, each mounting base 22 is provided with a pushing mechanism so that each lifting component 21 can move in the Z-axis, Y-axis and X-axis directions to adapt to multiple sets of front and rear wheels on both sides of the bogie. In this way, when multiple wheels on the bogie need to be maintained, the operator only needs to align the multiple wheels with the multiple lifting mechanisms 20 on the machine tool. When a single wheel needs to be lifted, the corresponding lifting component 21 is driven to move in the Z-axis, Y-axis or X-axis direction so that the lifting component 21 can be more accurately aligned with the wheel to accurately lift the wheel. There is no need to frequently move the bogie to the lifting mechanism 20, which indirectly saves maintenance time.

[0057] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
