Description

Technical Field

[0001] The utility model relates to the technical field of train washing devices, in particular to a railway train washing vehicle. Background Technique

[0002] With the development of railway transportation, the cleaning work of trains has become increasingly important. A clean train can not only provide passengers with a comfortable riding environment, but also extend the service life of the train and reduce maintenance costs. The traditional railway train cleaning method mainly relies on manual use of simple tools such as high-pressure water guns and brushes for cleaning. This method has a high labor intensity, low work efficiency, and unsatisfactory cleaning effect. Especially in the northeastern region, the outdoor temperature is relatively low, and the fixed gantry cleaning machines on both sides of the track cannot be used for outdoor cleaning. The train cleaning work can only be carried out in the vehicle depot maintenance shed. Although the existing cleaning vehicles can clean the outer surfaces of both sides of the train body, there are still many problems with the cleaning effect.

[0003] The severe cold climate in the northeastern region makes it necessary to carry out train cleaning work indoors. In order to ensure the cleaning effect of the train, the cleaning vehicle cleans the parked train in the vehicle depot maintenance shed. However, the existing cleaning vehicles mainly focus on cleaning the outer surfaces of both sides of the train body, and the cleaning effect on the side of the car body is not ideal. As Figure 10 and Figure 11 shown, the side of the car body is mostly an arc-shaped structure. Specifically, the side of the car body includes an upper top arc part and a lower bottom skirt part. The upper top arc part and the lower bottom skirt part are very difficult to clean, and manual cleaning operations are required for both, which is time-consuming and laborious. The traditional vertically arranged brushes are difficult to fully cover and clean thoroughly. This cleaning method not only increases the labor intensity of workers, but also leads to low work efficiency, and it is difficult to meet the needs of the rapid development of railway transportation.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 11 , the present utility model provides a railway train washing vehicle, including a traveling vehicle 1, a spraying mechanism 2 and a rotating brush mechanism 3. The rotating brush mechanism 3 includes an installation cover 31, a rotating brush shaft 32, brush bristles 33, a first motor 34, a driving rod 35 and a linear driving assembly 36.

[0031] The mounting cover 31 is connected to the walking vehicle 1. The mounting cover 31 is semi-circular. A hinge seat 311 is mounted on the bottom wall of the mounting cover 31. A shaft sleeve 321 is rotatably connected to the lower end of the brush roller shaft 32. The shaft sleeve 321 is rotatably connected to the hinge seat 311. The brush hairs 33 are distributed on the brush roller shaft 32. A first motor mounting bracket 341 is arranged outside the first motor 34. The first motor 34 is fixedly connected to the first motor mounting bracket 341. The upper end of the brush roller shaft 32 passes through the bottom wall of the first motor mounting bracket 341 and is rotatably connected to the bottom wall of the first motor mounting bracket 341. The driving rod 35 is fixedly connected to the first motor mounting bracket 341. An installation cavity 312 is arranged at the upper end of the mounting cover 31. The linear driving assembly 36 is installed in the installation cavity 312. A chute 313 is formed in the bottom wall of the installation cavity 312. The driving rod 35 passes through the chute 313 and is connected to the linear driving assembly 36.

[0032] During use, the walking vehicle 1 is driven to the side of the train 5, and the brush hairs 33 of the brush roller mechanism 3 are brought into contact with the side wall of the train. Subsequently, the spraying mechanism 2 and the brush roller mechanism 3 are started. The spraying mechanism 2 sprays water on the side wall of the train 5. At the same time, the first motor 34 drives the brush roller shaft 32 to rotate, and the brush roller shaft 32 drives the brush hairs 33 to rotate, and the rotating brush hairs 33 clean the side wall of the train 5. As Figure 9 and Figure 11 shown, when it is necessary to clean the upper top arc part 51 and the lower bottom skirt part 52 of the train 5, the linear driving assembly 36 is started. The linear driving assembly 36 drives the first motor mounting bracket 341 to move through the driving rod 35, and the first motor mounting bracket 341 drives the brush roller shaft 32 to rotate relative to the hinge seat 311. When it is necessary to clean the upper top arc part 51 of the train 5, the brush hairs 33 are adjusted to the second state as shown in Figure 11 shown. At this time, the side surface and the upper top arc part 51 of the train 5 can be cleaned by means of the brush hairs 33. When it is necessary to clean the lower bottom skirt part 52 of the train 5, the brush hairs 33 are adjusted to the first state as shown in Figure 10 shown. At this time, the side surface and the lower bottom skirt part 52 of the train 5 can be cleaned by means of the brush hairs 33.

[0033] By providing the walking vehicle 1, the spraying mechanism 2 and the brush roller mechanism 3, especially the mounting cover 31, the brush roller shaft 32, the brush hairs 33, the first motor 34, the driving rod 35 and the linear driving assembly 36 included in the brush roller mechanism 3, the cleaning vehicle can efficiently clean the train in the vehicle depot maintenance shed. At the same time, the angle of the brush roller shaft 32 is adjusted by the linear driving assembly 36, so that the brush hairs 33 can clean the side surface, the upper top arc part 51 and the lower bottom skirt part 52 of the train 5, eliminating the need for manual cleaning operations, reducing the manual labor intensity and improving the work efficiency.

[0034] Specifically, the linear drive assembly 36 includes a second motor 361, a screw 362, a first mounting block 363, a second mounting block 364, a sleeve 365, and a guide shaft 366. The second motor 361 and the guide shaft 366 are fixedly installed in the installation cavity 312. The output end of the second motor 361 is connected to the screw 362. One end of the screw 362 away from the second motor 361 is rotatably connected to the inner wall of the installation cavity 312. The screw 362 passes through the first mounting block 363 and is threadedly connected to the first mounting block 363. The guide shaft 366 passes through the second mounting block 364 and is slidably connected to the second mounting block 364. The sleeve 365 is connected between the first mounting block 363 and the second mounting block 364. The sleeve 365 is a rectangular sleeve, and the cross-section of the drive rod 35 is also rectangular. The drive rod 35 passes through the sleeve 365 and is slidably connected to the sleeve 365.

[0035] Start the second motor 361. The output end of the second motor 361 drives the screw 362 to rotate. The screw 362 drives the first mounting block 363 to perform a linear motion. The first mounting block 363 drives the sleeve 365 to perform a linear motion. The sleeve 365 drives the drive rod 35 to move. Since the motion of the drive rod 35 is a swing centered at the hinge seat 311, during the motion of the drive rod 35, it slides relative to the sleeve 365, and at the same time, the sleeve 365 also rotates relative to the first mounting block 363 following the drive rod 35. The driving of the drive rod 35 is realized, and at the same time, the drive rod 35 drives the brush roller shaft 32 to rotate relative to the hinge seat 311 through the first motor mounting bracket 341. Furthermore, the adjustment of the inclination angle of the bristles 33 is realized.

[0036] During the motion of the sleeve 365, the second mounting block 364 rotates relative to the guide shaft 366. The setting of the guide shaft 366 has a guiding effect on the motion of the sleeve 365, ensuring the smooth and stable motion of the sleeve 365.

[0037] Specifically, the number of the brush roller mechanisms 3 is two. Designing two brush roller mechanisms 3 can effectively improve the cleaning effect on the train 5.

[0038] Specifically, the spraying mechanism 2 includes a water storage tank 21, a pump 22, a three-way pipe 23, two spray pipes 24, and a plurality of nozzles 25. The water storage tank 21 is installed on the walking vehicle 1, and the pump 22 is also installed on the walking vehicle 1. The input end of the pump 22 is connected to the water storage tank 21, and its output end is connected to the three-way pipe 23. The two spray pipes 24 are respectively connected to the three-way pipe 23, and a plurality of nozzles 25 are equidistantly installed on each spray pipe 24. Among them, the spray pipe 24 is arranged on the side of the installation cover 31. After starting the pump 22, the pump 22 transports the water in the water storage tank 21 to the three-way pipe 23, and the water flow is distributed to the two spray pipes 24 through the three-way pipe 23, and finally sprayed onto the side of the train 5 by the nozzles 25 on the spray pipes 24. In order to improve the cleaning effect, detergent can be selectively added to the water storage tank 21, so as to enhance the dissolution and removal effect of the dirt on the side of the train 5.

[0039] Specifically, the nozzle 25 is a fan-shaped nozzle. The design of the fan-shaped nozzle can make the water flow evenly cover the surface of the train, increase the cleaning area, and improve the cleaning efficiency and effect. The water flow sprayed by the fan-shaped nozzle is fan-shaped, which can better cover the side of the train 5.

[0040] Specifically, a railway train washing vehicle further includes a lifting mechanism 4, and the brush rolling mechanism 3 is connected to the walking vehicle 1 through the lifting mechanism 4. Since trains 5 of different models may have different heights, the present invention also provides a lifting mechanism 4 to adjust the height of the brush rolling mechanism 3 through the lifting mechanism 4 to meet the cleaning requirements of trains of different heights.

[0041] Specifically, the lifting mechanism 4 includes a base 41, two rails 42, a hydraulic telescopic rod 43, a lifting frame 44, and a connecting rod 45. The base 41 is fixedly installed on the walking vehicle 1, the two rails 42 are fixedly connected to the base 41, the lifting frame 44 is slidably installed between the two rails 42, the hydraulic telescopic rod 43 is fixedly installed on the base 41, the output end of the hydraulic telescopic rod 43 is connected to the lifting frame 44, and the installation cover 31 is fixedly connected to the lifting frame 44 through the connecting rod 45.

[0042] When the height of the brush rolling mechanism 3 needs to be adjusted, start the hydraulic telescopic rod 43. The hydraulic telescopic rod 43 drives the lifting frame 44 to move upward. The lifting frame 44 drives the installation cover 31 to move upward through the connecting rod 45. The installation cover 31 drives the brush rolling shaft 32 and the brush bristles 33 to move upward, so as to effectively clean different height positions of the train 5. At the same time, after adjusting the height of the brush bristles 33, the angle of the brush bristles 33 can also be adjusted, which has strong practicability.

[0043] Specifically, rollers 46 are provided on the side of the lifting frame 44, and the rollers 46 are in contact with the inner wall of the track 42. The rollers 46 are designed to reduce the friction between the lifting frame 44 and the inner wall of the track 42. At the same time, they also make the lifting movement of the lifting frame 44 smoother.

[0044] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
