[0002] The bogie of a subway train is a core component of a subway vehicle, and its performance is directly related to the safety and stability of the train. During the long-term operation of a subway train, a large amount of dirt, such as dust, oil stains, and scale, will accumulate on the surface of the bogie. These dirts not only affect the appearance of the bogie, but may also have a negative impact on the performance of the bogie, such as reducing the lubrication effect and accelerating the wear of components. Therefore, it is very important to clean the bogie of a subway train regularly.

[0003] At present, the cleaning process of subway train bogies generally relies on the method of crane hoisting. Specifically, the bogies are hoisted to the designated cleaning pool for cleaning by crane. However, this traditional cleaning method has some significant shortcomings.

[0028] The following is combined with Figure 1 - Figure 6 The utility model is described in further detail.

[0029] The utility model embodiment discloses a subway train bogie cleaning tool.

[0030] Example 1

[0031] Reference Figure 1 - Figure 6A subway train bogie cleaning tool comprises a frame 1, a lifting and steering assembly 2 and a mounting frame 3, wherein the frame 1 is bolted to the top of a tank body 10. The device directly mounts the frame 1 on the tank body 10. To facilitate the installation and fixing of the frame 1, a U-shaped opening is provided at the bottom of the frame 1, the U-shaped opening is stuck at the top of the tank body 10, and then the frame 1 is fixed to the side of the tank body 10 by bolts to ensure the structural stability of the frame 1 when in use. When in use, firstly, the bogies that are in small batches or that are missed due to negligence and need to be cleaned separately are directly hoisted to the position of the frame 1 by driving, and then The bogie is placed on the mounting frame 3. To prevent the bogie from moving, a limit bolt 4 is evenly threadedly connected on the surface of the placement portion of the mounting frame 3. The limit bolt 4 can limit the bogie and effectively prevent it from moving. The threaded connection is easy to disassemble, and the connection position can be changed to adapt to bogies of different volumes. Then, the lifting steering assembly 2 on the frame 1 and the mounting frame 3 cooperate with each other to achieve the cleaning operation of small batches or bogies that need to be cleaned separately due to negligence. The use of this device ensures that the cleaning process no longer affects the normal use of the vehicle, thereby significantly improving the efficiency of transportation and cleaning.

[0032] The structure of the lifting and steering assembly 2 is as follows: the lifting and steering assembly 2 includes a base plate 21, a hydraulic lifting column 22, a guide rod 23, a lifting platform 24, a connecting column 25 and a rotating drive mechanism 26. The base plate 21, the hydraulic lifting column 22, the guide rod 23, the lifting platform 24, the connecting column 25 and the rotating drive mechanism 26 are all located inside the frame 1, and only one end of the connecting column 25 passes through the top of the frame 1 for fixed connection with the mounting frame 3. When in use, oil is supplied to the inside of the hydraulic lifting column 22 through an external hydraulic station. After the hydraulic lifting column 22 is supplied with oil, its top moves upward. The top of the hydraulic lifting column 22 moves upward and synchronously drives the lifting platform 24 to move upward along the inner wall of the frame 1 and the outer surface of the guide rod 23 respectively. The lifting platform 24 moves and synchronously drives the connecting column 25 and the rotating drive mechanism 26 to move upward synchronously. The connecting column 25 moves upward and synchronously drives the mounting frame 3 to move upward. The mounting frame 3 moves upward and synchronously drives the bogie placed on the mounting frame 3 to move upward. As the hydraulic oil is continuously injected into the hydraulic lifting column 22, the hydraulic lifting column 22 continues to drive the lifting platform 24, the connecting column 25, the rotating drive mechanism 26, the mounting frame 3 and the bogie to move upward. When the mounting frame 3 is higher than the top of the tank body 10, one end of the rotary drive mechanism 26 contacts the inner top wall of the frame 1 and is passively triggered. The triggering of the rotary drive mechanism 26 will synchronously drive the connecting column 25, the mounting frame 3 and the bogie to rotate, so that they slowly move from the outside of the tank body 10 to the inside of the tank body 10. When the rising stroke of the top of the hydraulic lifting column 22 reaches the maximum value, the rotary drive mechanism 26 has synchronously driven the connecting column 25, the mounting frame 3 and the bogie to rotate 180°. At this time, the mounting frame 3 and the bogie are already inside the tank body 10 and above the cleaning liquid. Then, The external hydraulic station discharges the hydraulic oil inside the hydraulic lifting column 22. With the reflux of the hydraulic oil, the top of the hydraulic lifting column 22 gradually descends until the hydraulic lifting column 22 is completely reset. In this process, the descent of the hydraulic lifting column 22 synchronously drives the lifting platform 24, the connecting column 25, the rotary drive mechanism 26, the mounting frame 3 and the bogie to descend. The bogie descends into the interior of the tank body 10 and is immersed in the cleaning liquid for cleaning operations. The descent of the rotary drive mechanism 26 is not triggered again, so that the bogie can maintain the set angle and descend vertically without contacting the tank body 10, and the use effect is good.

[0033] The structures and connection relationships of the above components are as follows: the bottom plate 21 is fixedly connected to the inner wall of the frame 1, the hydraulic lifting column 22 is fixedly connected to the top of the bottom plate 21, the guide rod 23 is evenly fixedly connected to the top of the bottom plate 21 and is located on the outside of the hydraulic lifting column 22, the lifting platform 24 is fixedly connected to the top of the hydraulic lifting column 22 and is sleeved on the outside of the guide rod 23, the lifting platform 24 is slidably connected to the inner wall of the frame 1 and the outer surface of the guide rod 23, the connecting column 25 is rotatably connected to the top of the lifting platform 24, one end of the connecting column 25 passes through the top of the frame 1 and is fixedly connected with the mounting frame 3, the rotating drive mechanism 26 is fixedly connected to the top of the lifting platform 24 and is located on one side of the connecting column 25, the rotating drive mechanism 26 is connected to the connecting column 25, and one end of the rotating drive mechanism 26 is connected to the inner top wall of the frame 1. It should be noted that in order to ensure the stable lifting of the lifting platform 24, a limiting boss is fixedly connected to the inner wall of the frame 1, a limiting groove is provided on the surface of the lifting platform 24, and the surface of the limiting boss is slidably connected to the inner wall of the limiting groove.

The one-way transmission 269 in the present device can only realize transmission when the lifting platform 24 rises. When the lifting platform 24 rises to a set height (that is, the bottom of the mounting frame 3 exceeds the top of the pool body 10), the top of the transmission rod 264 is aligned with the inner surface of the frame 1 The top wall is in contact, and under the extrusion of the frame 1, the transmission rod 264 moves vertically downward and compresses the spring 265. The transmission rod 264 moves downward and synchronously drives the cam 267 to move downward. The cam 267 moves downward and synchronously cooperates with the spiral guide groove 268 to synchronously drive the rotating drum 266 to rotate. The rotation of the rotating drum 266 synchronously drives the one-way transmission 269 to operate. The operation of the one-way transmission 269 synchronously drives the first gear 261 to rotate. The rotation of the first gear 261 synchronously drives the second gear 262 to rotate. The rotation of the second gear 262 synchronously drives the connecting column 25 to rotate, wherein the rotation angle of the connecting column 25 is between 0° and 180°. When it is at 0°, the bogie is located outside the pool body 10. When it is at 180°, the bogie moves to the inside of the pool body 10 and is located above the cleaning liquid.

When the switch is turned on, the annular electromagnet 52 is energized to tightly adsorb the surface of the connecting column 25, effectively preventing the connecting column 25 from rotating. When the switch is turned off, the annular electromagnet 52 is no longer magnetically fixed to the connecting column 25, and the connecting column 25 can rotate freely to achieve angle adjustment, with good use effect.
