Description

Technical Field

[0001] This utility model relates to the field of high-speed rail engineering technology, specifically to an automatic wheel disc flipping device for high-speed rail. Background Technology

[0002] During the disassembly and maintenance of EMU wheelsets, the wheel discs at both ends of the wheelset need to be unloaded and reassembled. This requires either flipping the vertically removed discs horizontally for placement or flipping the horizontally placed wheelset vertically before assembling it with the axle. Because the discs are large and heavy, traditional disc flipping processes typically require complex machinery and multiple manual operators, demanding high skill levels. This is not only time-consuming but also prone to accidents, especially dangerous for novice or physically weak workers. Furthermore, traditional manual flipping is susceptible to damage from human error, making it difficult to ensure the discs remain undamaged. Therefore, there is an urgent need for an automatic disc flipping device suitable for loading and unloading discs to overcome the aforementioned shortcomings of existing technologies. Utility Model Content

[0003] The purpose of this invention is to provide an efficient, convenient, safe and reliable automatic wheel disc flipping device for high-speed train wheelsets, which can quickly and automatically flip horizontally placed wheel discs into a vertical state or flip vertically placed wheel discs into a horizontal state, greatly shortening the flipping time and improving work efficiency.

[0004] To achieve the above objectives, this utility model is specifically implemented through the following technical solution:

[0005] An automatic wheel disc flipping device for high-speed trains includes a base, a flipping drive mechanism, a flipping seat, a wheel disc support frame, and a control cabinet. The flipping drive mechanism is movably mounted on one end of the base via a motor rotating frame, the flipping seat is movably mounted on the other end of the base via a rotating frame, and the wheel disc support frame is mounted on the top of the flipping seat.

[0006] The tilting drive mechanism includes a motor mounting bracket, a tilting drive motor, and a push rod. The motor mounting bracket is connected to the motor rotating frame. The housing of the tilting drive motor is fixedly mounted on the motor mounting bracket. The output end of the tilting drive motor is longitudinally connected to the push rod through a worm gear assembly. One end of the push rod is movably connected to the bottom of the tilting base. The control cabinet is connected to the tilting drive motor for control.

[0007] Furthermore, bearing seats are provided on both sides of the top of the motor frame and the rotating frame. The two sides of the motor fixed seat are movably connected to the motor frame through the bearing seats, and the two sides of the tilting seat are movably connected to the rotating frame through the bearing seats.

[0008] Furthermore, a connecting rod is horizontally arranged at the bottom of the flip seat, and the push rod is movably connected to the middle of the connecting rod.

[0009] Furthermore, the disc support frame is connected to the tilting seat via a lifting mechanism. The lifting mechanism includes a lifting drive module and a lifting guide rod mounted on the tilting seat. The disc support frame is mounted on the movable outer end of the lifting guide rod, and the lifting drive module is connected to the control cabinet.

[0010] Furthermore, a lifting sensor assembly is installed on the lifting drive module, and the lifting sensor assembly is connected to the control cabinet.

[0011] Furthermore, a horizontal tilting limit block and a vertical tilting limit block are provided on the outside of the tilting seat. The horizontal tilting limit block and the vertical tilting limit block abut against the rotating frame and limit the movement in the horizontal and vertical states, respectively.

[0012] Furthermore, a horizontal flip sensor and a vertical flip sensor are installed on the outside of the flip seat. The horizontal flip sensor and the vertical flip sensor sense the rotating frame in the horizontal and vertical states, respectively.

[0029] like Figures 1 to 4 As shown, this utility model discloses an automatic wheel disc reversing device for high-speed trains, comprising a base 1, a reversing drive mechanism 2, a reversing seat 3, a disc support frame 5, and a control cabinet. The reversing drive mechanism 2 is movably mounted on one end of the base 1 via a motor rotating frame 7, and the reversing seat 3 is movably mounted on the other end of the base 1 via a rotating frame 8. The disc support frame 5 is mounted on top of the reversing seat 3. This utility model's reversing device is integrated into a conveyor line or other equipment requiring connection, integrating automatic loading and unloading functions. It can automatically reverse horizontal wheel discs transported by the conveyor line into an upright state, facilitating manual lifting and transfer. Alternatively, manually lifted upright wheel discs can be placed on the reversing device to automatically reverse them into a horizontal state.

[0030] The flipping drive mechanism 2 includes a motor mounting bracket 21, a flipping drive motor 22, and a push rod 23. The motor mounting bracket 21 is connected to the motor rotating bracket 7. The housing of the flipping drive motor 22 is fixedly mounted on the motor mounting bracket 21. The output end of the flipping drive motor 22 is longitudinally connected to the push rod 23 through a worm gear assembly. One end of the push rod 23 is movably connected to the bottom of the flipping base 3. The control cabinet is connected to the flipping drive motor and the start and stop of the flipping are controlled by the buttons on the control cabinet.

[0031] The push rod 23 and the worm gear assembly form a worm gear transmission. The rotation output end of the flip drive motor 22, which is fixed on the motor mounting bracket 21, drives the push rod 23 longitudinally through the worm gear assembly, which further pushes the bottom of the flip seat 3 to swing back and forth to achieve flipping. During the flipping process, the push rod 23 has a small amplitude swing. Therefore, through the rotational connection between the motor rotating bracket 7 and the motor mounting bracket 21, the flip drive motor can also swing during the flipping process, ensuring that the worm gear transmission between the push rod 23 and the flip drive motor 22 will not disengage.

[0032] The control cabinet is equipped with a control button box, which can have only three buttons: one horizontal, one vertical, and one emergency stop. Users can perform the wheel disc flipping action with a single button operation without professional training, greatly reducing the difficulty of operation and improving the ease of use of the device. Its high-power motor, combined with a wide-range wheel disc bearing platform, enables it to adapt to various sizes and weights of high-speed rail wheel discs, making it widely applicable.

[0033] In a preferred embodiment, bearing seats 9 are provided on both sides of the top of the motor frame 7 and the rotating frame 8. The motor fixing seat 21 is movably connected to the motor frame 7 on both sides through the bearing seats 9, and the flipping seat 3 is movably connected to the rotating frame 8 on both sides through the bearing seats 9.

[0034] In some embodiments, a connecting rod 31 is horizontally arranged at the bottom of the flip seat 3, and the push rod 23 is movably connected to the middle of the connecting rod 3.

[0035] In a further preferred embodiment, the disc support frame 5 is connected to the tilting seat 3 via a lifting mechanism 4. The lifting mechanism 4 is mounted on the top surface of the tilting seat 3, and the disc support frame 5 is mounted on the top surface of the lifting mechanism 4. The control cabinet is connected to the lifting mechanism 4. The lifting mechanism 4 includes a lifting drive module 41 and a lifting guide rod 42 mounted on the tilting seat 3. The lifting drive module 41 can be a cylinder. The disc support frame 5 is mounted on the movable outer end of the lifting guide rod 42. The lifting drive module is connected to the control cabinet. The cylinder of the lifting drive module 41 uses compressed air to drive the piston rod and the lifting guide rod 42 to move up and down, realizing the lifting and lowering action. The disc support frame 5 is mounted above the lifting mechanism 4, driving the entire disc support frame 5 to move up and down, the purpose of which is to detach the disc from the conveyor line and other equipment, preventing collisions during the tilting process.

[0036] In a preferred embodiment, a lifting sensor assembly is installed on the lifting drive module 41. The lifting sensor assembly is connected to the control cabinet. The lifting sensor assembly can be configured as two status position sensors for extension and retraction. The sensor type can be a magnetic switch, used to determine whether the lifting platform has extended to the correct position and whether it has retracted to the correct position. Only after the position signal is triggered can the next action be performed to ensure safety.

[0037] In some embodiments, a horizontal flipping limit block 32 and a vertical flipping limit block 33 are provided on the outside of the flipping seat 3. The horizontal flipping limit block 32 and the vertical flipping limit block 33 abut against the rotating frame 8 in the horizontal and vertical states, respectively, which can limit the extreme position during the flipping of the disc, forcibly stop the flipping action, prevent the flipping action from not stopping under abnormal conditions, damage the equipment or cause a safety accident, and prevent accidents from happening.

[0038] In a preferred embodiment, a horizontal flip sensor 34 and a vertical flip sensor 35 are provided on the outside of the flip base 3. The horizontal flip sensor 34 and the vertical flip sensor 35 sense the rotating frame 8 in the horizontal and vertical states, respectively. Both the horizontal flip sensor 34 and the vertical flip sensor 35 are connected to the control cabinet.

[0039] In some embodiments, the disc support frame 5 includes a base frame 51 and a top frame 52. A buffer limit block 53 is provided between the base frame 51 and the top frame 52, and anti-slip blocks 54 are provided on the inner sides of the top frame 52 and the base frame 51. The buffer limit block 53 can limit the extreme position of the disc within the disc support frame 5 during the disc flipping process, preventing the flipping action from continuing under abnormal conditions, thus preventing damage to the equipment or safety accidents. The anti-slip blocks 54 can support and position the disc within the disc support frame 5, and also provide buffering and anti-slip functions.

[0040] The specific embodiments described herein are merely illustrative of the invention and are not intended to limit it. Those skilled in the art can make modifications to these embodiments without contributing any inventive step after reading this specification, but such modifications are protected by patent law as long as they fall within the scope of the claims of this invention.
