Description

Technical Field

[0001] This utility model relates to the technical field of guide rail type vehicle roof cleaning device, specifically a guide rail type vehicle roof cleaning device. Background Technology

[0002] The rail-guided carriage roof cleaning device is a specialized piece of equipment for the automated cleaning of the roofs of rail vehicles such as trains, subways, and light rails. These rail vehicles accumulate dirt, bird droppings, and other stains during operation and use. Due to their height, it is difficult to clean the roofs during routine cleaning, leading to the accumulation of dirt that affects the vehicle's appearance and can cause rust, accelerating the vehicle's aging. Therefore, it is necessary to clean the carriage roofs.

[0003] Currently, the cleaning of the roof of rail-guided carriages mainly relies on roller brushes. This involves spraying cleaning agent onto the roof and using a motor-driven roller brush to scrub the surface as the vehicle passes at a constant speed. However, different carriage models have different roof structures. For example, some freight carriages lack pantographs and vents, while passenger carriages do. Furthermore, different vehicle models have different roof shapes; some carriages have rounded or sloping roofs. Because existing cleaning methods cannot accurately conform to the different shapes of the carriage roofs and cannot clean stains around the pantograph or vents, the cleaning scope is limited and the cleaning effect is poor. Therefore, to address these issues, a rail-guided carriage roof cleaning device is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, and to address the problems that existing technologies cannot be applied to cleaning the roofs of carriages with different structures and shapes, and cannot clean the protruding parts of the carriages, resulting in a limited scope of application and poor cleaning effect, this utility model proposes a rail-guided carriage roof cleaning device.

The spray washing assembly 3 includes a No. 3 fixing plate 31 fixed to the side of the lifting plate 12. Multiple fixing pipes 32 are fixed through the No. 3 fixing plate 31, and the top ends of the multiple fixing pipes 32 are connected to an external steam generating device through hoses. Rotating sleeves 33 are rotatably installed at the bottom ends of the fixing pipes 32. End caps 34 are fixed to the bottom ends of the rotating sleeves 33. Evenly distributed nozzles 35 are provided on the outer wall of the end caps 34. Impellers 36 are fixed inside the rotating sleeves 33.

[0018] The multiple brushing components 2 are arranged in two rows horizontally, with the two rows of brushing components 2 staggered. The spraying components 3 are connected to an external steam generator via hoses. A second fixing plate 15 is horizontally fixed inside the support frame 11, and the second fixing plate 15 is located on the side opposite to the lifting plate 12 of the spraying components 3. A second nozzle 16 is evenly distributed under the second fixing plate 15. A second infrared rangefinder 18 is evenly distributed under the first infrared rangefinder 17. A first nozzle 14 is evenly distributed under the first fixing plate 13.

[0019] An annular limiting plate 23 is fixedly connected to the bottom opening of the transmission sleeve 22, and the limiting rod 26 is inserted through the hole in the middle of the annular limiting plate 23. The annular limiting plate 23 is provided with a guide groove 27 in the middle hole, and a guide strip 28 is provided on the side wall of the limiting rod 26 to slide and limit the guide groove 27.

[0020] The drive assembly 4 includes an inner spline sleeve 41 that passes through and is rotatably mounted on the top of the support frame 11. A spline shaft 42 is slidably fitted inside the inner spline sleeve 41, and the bottom end of the spline shaft 42 is fixed to the top of one of the pulleys 211.

[0021] A first gear 43 is fixedly connected to the outer wall of the inner spline sleeve 41. A second gear 45 is provided next to the first gear 43 and is connected to it in a transmission. A motor 44 is provided on the second gear 45 and is connected to it in a transmission. The motor 44 is fixed on the support frame 11.

[0022] The lifting assembly 5 includes a lifting groove 51 opened on the side wall of the support frame 11. A support plate 52 is fixed to the lower edge of the opening of the lifting groove 51. Two hydraulic rods 53 are fixed on the support plate 52. Pressure sensors 54 are fixed to the top of each of the two hydraulic rods 53. The lifting plate 12 is simultaneously fixed to the two pressure sensors 54 inside the two lifting assemblies 5.

[0023] During operation, the existing cleaning method cannot accurately adhere to the top of the carriage with different shapes and cannot clean the stains at the pantograph or vent, resulting in a small cleaning range and poor cleaning effect. In this solution, in the initial state, the spring 25 will always push the baffle 24 downward so that the baffle 24 adheres to the annular limiting plate 23, thereby keeping the limiting rod 26 in the extended state. During use, the train is controlled to pass under the support frame 11 and from the side opposite to the spray washing assembly 3 of the lifting plate 12. At this time, the infrared rangefinder 17 will detect the distance between it and the top of the train in order to control the falling height of the lifting plate 12. When the lifting plate 12 falls, the hydraulic rod 53 is controlled to retract, thereby driving the lifting plate 12 and its components to descend. The cleaning is then evenly sprayed on the surface of the carriage using the nozzle 14 to make the stains easier to remove. When the lifting plate 12 descends to a certain height, the brush plate 210 will adhere to the top of the train, and the control hydraulic rod 53 will continue to retract. At this time, the baffle 24 will press the spring 25 upward to retract it, and the limit rod 26 will retract into the transmission sleeve 22. By making the extension and retraction lengths of multiple limit rods 26 different, it can be adapted to cleaning the top of the carriage with different shapes. At this time, under the universal transmission action of the universal joint 29, the brush plate 210 can adaptively adhere to the top of the train to clean the top of the carriage with different shapes. When the brush plate 210 adheres to the surface of the carriage, under the reaction force of the spring 25, the weight of the component borne by the pressure sensor 54 will also be reduced, which makes it easier to monitor the adhesion pressure between the brush plate 210 and the surface of the carriage, ensuring that the brush plate 210 has sufficient downward pressure to clean the stains and ensure the cleaning effect. In coordination with the operation of the control motor 44, the motor 44 drives the inner spline sleeve 41 to rotate. When the inner spline sleeve 41 rotates, it drives one of the pulleys 211 connected to it at the bottom to rotate through the spline shaft 42. The adjacent brushing components 2 are connected by belt drive, so that multiple brushing components 2 can rotate. The pulley 211 drives the drive shaft 21 to rotate, and the drive shaft 21 drives the drive sleeve 22 to rotate. Under the sliding engagement limit of the guide bar 28 and the guide groove 27, the limit rod 26 is driven to rotate. The limit rod 26 drives the brush plate 210 to rotate through the universal joint 29. Under the action of the universal joint 29, the brush plate 210 can rotate at different angles, thereby cleaning the top of the carriage with different shapes, effectively improving the cleaning application range and the cleaning effect. Then, the carriage is moved under the second fixed plate 15, and the second nozzle 16 can be used to rinse the washed carriage with clean water in order to wash away the stains. As the carriage moves forward, the first infrared rangefinder 17 continuously monitors its distance from the top of the carriage. When the carriage structure has components such as a pantograph, the distance data detected by the first infrared rangefinder 17 will decrease. The data detected by the first infrared rangefinder 17 and the second infrared rangefinder 18 will be transmitted to the control terminal simultaneously. When the detected distance value decreases, the terminal equipment will immediately control the hydraulic rod 53 to extend, thereby raising the height of the lifting plate 12 and its components, thus preventing damage from collisions between the carriage components and the cleaning device. At this time, the terminal equipment will also control the steam generator to operate, delivering high-temperature steam to the spray washing group. Inside component 3, when steam enters the spray cleaning assembly 3, it will enter multiple fixed pipes 32 respectively, and then enter the rotating sleeve 33 through the fixed pipes 32. Due to the high speed of the steam, the impeller 36 will rotate, which will in turn drive the rotating sleeve 33 and the end cover 34 to rotate. When the end cover 34 rotates, the high temperature steam will be sprayed through the nozzle 35, which will then perform high temperature steam multi-angle washing on the pantograph and other components passing below, so as to clean the stains on the pantograph and other components. When the pantograph and other components pass under the second infrared rangefinder 18, the hydraulic rod 53 will retract again so that the brush plate 210 will re-adhere to the surface of the carriage. It effectively cleans the roof of the carriage and can clean the roof of carriages with different shapes and structures, thus improving the applicability of the carriage cleaning device and achieving better cleaning results.
