Description

Technical Field

[0001] This utility model relates to the field of EMU fan replacement technology, and in particular to an EMU fan replacement device based on an electric push rod. Background Technology

[0002] In the design of high-speed trains, the various fans under the train play a crucial role. These fans, including the condenser fan for the driver's cab air conditioning and the exhaust fan for the passenger compartment air conditioning, together form a complex and precise heat dissipation network. This network effectively removes the heat generated by critical components during operation, ensuring that the components operate within a suitable temperature range. This not only reduces component wear and tear and improves overall operating efficiency but also extends component lifespan and reduces the risk of component damage due to excessive temperature, thereby significantly improving the quality of train operation and maintenance.

[0003] The fans in high-speed trains not only reduce component wear and improve overall operating efficiency, but also extend component lifespan and reduce the risk of component damage caused by excessive temperature, thus significantly improving the operation and maintenance quality of high-speed trains. Therefore, it is necessary to inspect the fans in high-speed trains every once in a while.

[0004] During maintenance, replacing a wind turbine requires the cooperation of two maintenance personnel. One person is responsible for disassembling and replacing the turbine's bolts, while the other person needs to steadily support the turbine throughout the operation. Due to the large size and weight of the turbine, the workload of the workers is increased, and the turbine may fall and cause injury. Utility Model Content

[0005] The purpose of this utility model is to provide a high-speed train fan replacement device based on an electric push rod, so as to solve the problem mentioned in the background art that in the maintenance operation, the fan replacement requires two maintenance personnel to work together, which increases the workload.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A train fan replacement device based on an electric push rod includes a mounting plate and a transmission assembly. The transmission assembly is disposed on the top of the mounting plate and includes a control box. The control box is fixedly connected to the top of the mounting plate. A stepper motor is fixedly connected to the top of the control box. A drive shaft is fixedly connected to the bottom of the stepper motor. A gear is fixedly connected to the bottom of the drive shaft. A lead screw is fixedly connected to the inner side of the gear. A bearing is fixedly connected to the outer side of the lead screw. A synchronization controller is disposed on one side of the control box, and a support assembly is disposed on the top of the control box.

[0008] More preferably, the support assembly includes an outer shell, which is fixedly connected to the top of the control box. A slider is provided inside the outer shell, a buffer rubber ring is fixedly connected to the top of the lead screw, a push rod inner tube is movably connected inside the outer shell, a load-bearing plate is fixedly connected to the top of the push rod inner tube, and a sliding assembly is provided on the top of the load-bearing plate. By installing the sliding assembly, fans of different sizes and models can be clamped.

[0009] More preferably, the sliding component includes a support plate, which is fixedly connected to the top of the load-bearing plate. A groove is provided on the top of the load-bearing plate, and a second slider is slidably connected to the inner side of the groove. Extension plates are fixedly connected to both sides of the second slider, and a fixing component is provided on the top of the extension plate. By installing the fixing component, the second slider can be prevented from sliding.

[0010] More preferably, the fixing component includes a threaded hole one, which is opened at the top of the extension plate. The inner cavity of the threaded hole one is threadedly connected to a threaded rod, and an adjustment knob is fixedly connected to the top of the threaded rod. The top of the support plate is provided with a threaded hole two, and the bottom of the mounting plate is provided with a moving component. By installing the moving component, the direction of movement of the device can be controlled by the casters during movement. On a flat road surface, the planetary wheels are limited by the simultaneous contact of two wheels with the ground, and do not rotate. When the device encounters a high obstacle, the rotating shaft drives the planetary wheels to rotate for alternating support, allowing the device to flexibly overcome the obstacle.

[0011] More preferably, the movable component includes a support plate, which is fixedly connected to the bottom of the mounting plate. A mounting base is fixedly connected to the bottom of the support plate. A rotating hole is opened on the inner side of the mounting base. A rotating shaft is rotatably connected to the inner cavity of the rotating hole. A planetary gear is sleeved on the outer side of the rotating shaft. A universal wheel is provided on one side of the planetary gear. A handle is fixedly connected to the other side of the support plate. A storage component is provided on the top of the support plate.

[0012] More preferably, the storage component includes a storage box, which is disposed on the top of the support plate. A buckle is snapped onto the outer side of the outer shell, and the buckle is fixedly connected to the storage box. A partition is fixedly connected to the inner side of the storage box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) In this utility model, by installing transmission components and support components, four stepper motors are controlled to start working simultaneously by a synchronous controller. The stepper motors drive the six gears inside the control box to form a speed change structure. After the speed change structure changes speed, it pushes the inner tube of the push rod to move, so that the support plate contacts the bottom of the EMU fan and supports the fan. There is no need for two workers to carry out maintenance, reducing the workload and preventing personnel injury.

[0015] (2) In this utility model, by installing the moving component, the direction of movement of the device can be controlled by the universal wheel when moving. The planetary wheel is restricted from rotating on a flat road surface because the two wheels are in contact with the ground at the same time. When the device encounters a high obstacle, the rotating shaft drives the planetary wheel to rotate for alternating support, so that the device can flexibly overcome the obstacle.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, the support assembly 3 includes an outer shell 301, which is fixedly connected to the top of the control box 201. A slider 302 is provided inside the outer shell 301. A buffer rubber ring 303 is fixedly connected to the top of the lead screw 205. A push rod inner tube 304 is movably connected inside the outer shell 301. A load-bearing plate 305 is fixedly connected to the top of the push rod inner tube 304. A sliding assembly 4 is provided on the top of the load-bearing plate 305. The lead screw 205 pushes the push rod inner tube 304 to move within the outer shell 301, and the slider 302 inside the outer shell 301 acts as a limit. Then, the push rod inner tube 304 pushes the support plate 401 to contact the bottom of the train fan.

[0029] In this embodiment, as Figure 1 and Figure 6 As shown, the sliding component 4 includes a support plate 401, which is fixedly connected to the top of the load-bearing plate 305.

A threaded rod 502 is threadedly connected to the inner cavity of the threaded hole 501. An adjusting knob 503 is fixedly connected to the top of the threaded rod 502. A threaded hole 504 is located on the top of the support plate 401. A moving component 6 is located at the bottom of the mounting plate 1. The adjusting knob 503 is used to screw the threaded rod 502 into the threaded holes 501 and 504 to fix the slider 403 and ensure the stability of the train's fan during disassembly.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the moving component 6 includes a support plate 601, which is fixedly connected to the bottom of the mounting plate 1. A mounting base 602 is fixedly connected to the bottom of the support plate 601. A rotating hole 603 is provided on the inner side of the mounting base 602.

On a flat road surface, the planetary gear 605 is limited by the two wheels contacting the ground at the same time and does not rotate. When the device encounters a high obstacle, the rotating shaft 604 drives the planetary gear 605 to rotate and provide alternating support, so that the device can flexibly overcome the obstacle.

[0032] In this embodiment, as Figure 1 and Figure 7 As shown, the storage component 7 includes a storage box 701, which is located on top of the support plate 601.

[0033] The usage method and advantages of this utility model: The working process of this EMU fan replacement device based on electric push rod is as follows:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, when using the device, the operator first disconnects the power to the synchronization controller 207, then presses and releases the up and down buttons on the remote control. After the remote control indicator light flashes for two seconds, the synchronization controller 207 is reconnected for ten seconds. Pressing the remote control button again indicates successful pairing. The operator then moves the device to the desired location using the handle 607. During movement, the universal wheels 606 control the device's direction. On a flat surface, the planetary gears 605, due to the limitation of two wheels simultaneously contacting the ground, do not rotate. When the device encounters a high obstacle, the shaft 604 drives the planetary gears 605 to rotate, providing alternating support, allowing the device to flexibly overcome obstacles. The synchronization controller 207 then controls four stepper motors 202 to start working simultaneously. The stepper motors 202 drive the drive shaft 203, which in turn drives the gear 204, controlling... The box 201 contains six gears 204, which form a speed-changing structure. After the speed-changing structure changes speed, the gears 204 drive the lead screw 205 to rotate, and the lead screw 205 pushes the inner tube of the push rod 304 to move in the outer shell 301. The slider 302 inside the outer shell 301 acts as a limit. Then, the inner tube of the push rod 304 pushes the support plate 401 to contact the bottom of the EMU fan. The position of the slider 403 inside the slide groove 402 is adjusted according to the size and shape of the EMU fan. Then, the adjusting knob 503 is used to screw the threaded rod 502 into the threaded hole 501 and the threaded hole 504 to fix the slider 403 and ensure the stability of the EMU fan during disassembly. Finally, during disassembly, the staff can place the tools in the storage box 701 according to their model, and the tools are separated by the partition plate 703.
