Description

Technical Field

[0001] This utility model relates to the field of wheelset and bogie replacement technology, and specifically to a wheelset and bogie replacement device. Background Technology

[0002] Wheelset bogies are an important component of railway locomotives and rolling stock, playing a crucial role in train operation. They are devices that press-fit one axle and two wheels together. During operation, the motor transmits power to the wheelset through a transmission system consisting of the power transmission line and the bogie, propelling the entire train to move.

[0003] Wheelset bogies require maintenance after a period of use. During maintenance, the entire vehicle frame needs to be supported to facilitate bogie replacement. However, in some cases, the width of the vehicle bogies may differ, which can lead to compatibility issues during replacement.

[0004] According to Chinese Patent Publication No. CN219115457U, "A Bogie (Wheelsset) Replacement Device," the device mainly describes a system consisting of a fixed mounting block, a fixed hydraulic rod, a fixed connector, a fixed connecting rod, and a fixed support mechanism. When the device is moved to a designated position, the fixed hydraulic rod presses downwards on the fixed connector and the fixed connecting rod, thus acting on the fixed support mechanism. This allows the fixed support mechanism to interact with the ground, providing support and fixation for the entire device. While allowing movement of the device, it also ensures its stability and ease of use. However, during vehicle bogie maintenance, the width of the vehicle bogie may differ from the replacement device, leading to compatibility issues during replacement.

[0005] Therefore, a wheelset bogie replacement device is proposed to solve the problem that the width of the vehicle bogie may differ from that of the replacement device during vehicle bogie maintenance, which can easily lead to compatibility issues during replacement. Utility Model Content

[0006] The technical problem to be solved by this utility model is that during the maintenance of vehicle bogies, the width of the vehicle bogie may differ from that of the replacement equipment, which may lead to compatibility issues during replacement. Therefore, a wheelset bogie replacement equipment is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a wheelset bogie replacement device, including a base plate and a movable wheel. Two base plates are provided. A first motor is fixedly connected to one base plate, and an adjusting rod is fixedly connected to the output end of the first motor. A fixing sleeve is threaded onto the adjusting rod, and the fixing sleeve is fixedly connected to the other base plate. Grooves are provided on opposite sides of both base plates. A second motor is fixedly connected to one base plate located on the side of the groove. A first screw is fixedly connected to the output end of the second motor. A movable plate is threaded onto the first screw. A clamp is in contact with the upper end of the movable plate. A second screw is rotatably connected to the bottom end of the clamp. The second screw is threadedly connected to the movable plate. A connecting plate is rotatably connected to the bottom end of the second screw. A third motor is fixedly connected to the bottom end of the connecting plate, and the output end of the third motor is fixedly connected to the second screw.

[0008] As a preferred technical solution of this utility model, an extension plate is inserted into the movable plate. The extension plate is located between the two base plates. By setting the extension plate, the width between the two base plates can be easily adjusted.

[0009] As a preferred technical solution of this utility model, a positioning rod is threadedly connected to the movable plate, and the end of the positioning rod contacts the extension plate. By setting the positioning rod, the extension plate and the movable plate can be limited.

[0010] As a preferred technical solution of this utility model, the upper sides of the base plate are rotatably connected to support plates, one side of the support plate is fixedly connected to a bracket, and the end of the bracket away from the support plate is fixedly connected to a pad. By setting the pad and support plate, the contact surface between the bogie and its support device and the replacement equipment is increased, thereby improving the stability during replacement.

[0011] As a preferred technical solution of this utility model, a synchronization plate is in contact with the moving plate, and the synchronization plate is fixedly connected to one side of the clamp by bolts. By setting the synchronization plate, the stability of the clamp can be increased.

[0012] As a preferred technical solution of this utility model, a connecting sleeve is fixedly connected to the bottom end of the moving plate, a pressure rod is threadedly connected to the bottom end of the connecting sleeve, and a turntable is fixedly connected to the pressure rod. By setting the connecting sleeve and the pressure rod, the friction can be increased and the equipment can be prevented from shaking.

[0013] The present invention has the following advantages: by setting a fixing sleeve and an adjusting rod between the two base plates, the distance between the two base plates can be adjusted. At the same time, the upper support plate and the pad on the base plate provide support, and the moving plate is driven to move by the first screw, which can provide position adjustment, facilitate the connection between the clamp and the bogie shaft, and improve adaptability.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-3 The diagram illustrates a wheelset bogie replacement device, comprising a base plate 1 and movable wheels 2. Two base plates 1 are provided. A first motor is fixedly connected to one base plate 1, and an adjusting rod 3 is fixedly connected to the output end of the first motor. The first motor drives the adjusting rod 3 to rotate, thereby increasing or decreasing the distance between a fixed sleeve 4 and the adjusting rod 3, thus adjusting the distance between the two base plates 1 to accommodate different bogie axles. A fixed sleeve 4 is threaded onto the adjusting rod 3, and the fixed sleeve 4 is fixedly connected to the other base plate 1. Grooves are formed on opposite sides of both base plates 1. A second motor is fixedly connected to one base plate 1 located on the side with the groove. The second motor drives a first screw 5 to rotate, enabling… The movable plate 6 can move on one side of the base plate 1, and drive the clamp 7 to move, so that the clamp 7 corresponds to the shaft of the bogie. The output end of the second motor is fixedly connected to the first screw 5, and the movable plate 6 is threadedly connected to the first screw 5. The upper end of the movable plate 6 contacts the clamp 7. The bottom end of the clamp 7 is rotatably connected to the second screw 8, and the second screw 8 is threadedly connected to the movable plate 6. The bottom end of the second screw 8 is rotatably connected to the connecting plate 9, and the bottom end of the connecting plate 9 is fixedly connected to the third motor. The output end of the third motor is fixedly connected to the second screw 8. The third motor drives the second screw 8 to rotate, which can cause the clamp 7 to move upward, so that a gap appears between the bogie and the replacement equipment, making it easier to replace.

[0020] Among them, the movable plate 6 is connected to the extension plate 10, which is located between the two base plates 1. By setting the extension plate 10, it can provide adaptive changes after the fixed sleeve 4 and the adjusting rod 3 are adjusted.

[0021] The extension plate 10 contacts the end of the positioning rod 11, and the positioning rod 11 is threadedly connected to the moving plate 6. By setting the positioning rod 11, the pressure on one side of the moving plate 6 and the extension plate 10 is increased, thereby improving the stable connection effect.

[0022] The pad 13 is fixedly connected to the side of the bracket away from the support plate 12, and the support plate 12 is rotatably connected to both sides of the upper end of the base plate 1. By setting the pad 13 and the support plate 12, the contact surface can be increased and the adaptability of the replacement equipment to different chassis can be improved.

[0023] One side of the clamp 7 is fixedly connected to the synchronization plate 14 by bolts. The synchronization plate 14 is in contact with the upper side of the moving plate 6. By setting the synchronization plate 14, the two clamps 7 can move synchronously, thus improving stability.

[0024] The turntable 17 is fixedly connected to the pressure rod 16, the pressure rod 16 is threaded to the bottom end of the connecting sleeve 15, and the connecting sleeve 15 is fixedly connected to the bottom end of the moving plate 6. By setting the pressure rod 16 and the connecting sleeve 15, the pressure rod 16 can be connected to the ground to increase the friction, thereby preventing the moving wheel 2 from moving.

[0025] Working principle: The first motor drives the adjusting rod 3 to rotate, which increases the distance between the adjusting rod 3 and the fixed sleeve 4. Then, the positioning rod 11 limits the distance between the extension plate 10 and the moving plate 6, moving the device to the bottom of the bogie. At the same time, the second motor drives the first screw 5 to rotate, causing the moving plate 6 to move laterally to correspond to the axle of the bogie. The clamp 7 is moved upward by the third motor driving the second screw 8 to provide a limit. The support plate 12 and the pad plate 13 increase the contact surface and improve the stability of the bogie. At this time, the adjusting rod 16 makes the bottom end of the rod 16 contact the ground, providing friction and preventing the moving wheel 2 from moving due to external force, thus enabling the bogie to be replaced.

[0026] The above are merely preferred embodiments of this utility model. 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 should also be considered within the scope of protection of this utility model.

[0027] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
