Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically a high-pressure cleaning device for train carriages. Background Technology

[0002] In railway bulk cargo transportation, various materials often remain on the internal surfaces of open wagons, ore wagons, and other train carriages after unloading or before reloading. These residues mainly include particles scattered on the floor, dust adhering to the side walls and roof, and clumps of material accumulated around connecting components such as couplers. If not thoroughly cleaned, this not only directly affects the accuracy of subsequent loading measurements and the consistency of cargo composition, but may also cause doors to malfunction or couplers to fail due to debris intruding into the door guide rails or coupler mechanism, creating potential safety hazards for train operation.

[0003] To improve cleaning efficiency, the industry has already introduced large-scale mechanized cleaning devices. These devices mostly use fixed-position gas jet or blowing pipes, or actuators with only simple reciprocating or oscillating functions. While these designs can clean particulate dust over large areas of the vehicle compartment, they struggle in areas such as corners, such as narrow transition zones along the edges of the roof, the bends where side and end walls meet, and especially the areas around the hook-up connections that are irregularly shaped, extremely cramped, and poorly visible. Existing devices cannot drive the nozzles to make flexible multi-angle adjustments, nor can they achieve precise alignment and close-range effectiveness with these uneven surfaces or hidden recesses. This makes these critical blind spots cleaning dead zones, seriously affecting the overall cleaning quality. Utility Model Content

[0004] To address the problem that large cleaning equipment not only occupies a lot of space but also makes it difficult to clean the corners of train carriages, this utility model provides a high-pressure cleaning device for train carriages.

[0005] This utility model is achieved through the following technical solution: A high-pressure cleaning device for train carriages includes a water tank, the outlet of which is connected to a pressurized water pump, the pressurized water pump pipeline being connected to a spray cleaning plate, the spray cleaning plate having nozzles evenly distributed thereon; an angle adjustment component is provided on one side of the spray cleaning plate, the angle adjustment component being connected to the spray cleaning plate and adjusting the rinsing direction of the spray cleaning plate; the angle adjustment component is mounted on a second base, the second base being slidably mounted on the track.

[0006] The spray cleaning plate, through the cooperation of the angle adjustment component and the movement of the second base along the track, helps to increase the cleaning area applied to the carriage, provide targeted treatment for corners, and achieve structural optimization, reducing the footprint.

[0007] A further improvement of this invention is that the aforementioned angle adjustment assembly includes a support arm, an adjusting arm, and a telescopic cylinder. The support arm is vertically mounted on the second base, and the adjusting arm is hinged to the top of the support arm. One end of the adjusting arm is connected to a spray plate, and the other end is hinged to a telescopic cylinder. One end of the telescopic cylinder is connected to the adjusting arm, and the other end is connected to the second base. With the cooperation of the support arm, the stability of the adjusting arm's rotation is achieved, thereby controlling the pitch angle of the spray plate. While covering corner areas, the tilted cleaning direction enhances the cleaning power.

[0008] A further improvement of this invention is that the spray surface of the aforementioned spray plate has an obtuse angle structure in the vertical plane; the nozzles are evenly distributed on the spray surface of the spray plate. This helps to improve the combined coverage area and impact effect of the rinsing flow; the obtuse angle structure allows the high-speed medium ejected from the nozzles to naturally form a certain diffusion angle in space, allowing a wider strip area to be covered in a single rinse; at the same time, this structure helps to concentrate the impact force in a more effective direction, which is beneficial for removing stubborn deposits and avoids uneven cleaning results.

[0009] A further improvement of this invention is that the aforementioned angle adjustment component is mounted on the second base via a support platform. The support platform helps to increase the installation height of the angle adjustment component, thereby optimizing the optimal rotation height of the spray wash plate and achieving compatibility with the carriage.

[0010] A further improvement of this utility model is that a first connecting rigid pipe is fixedly installed on the second base. One end of the first connecting rigid pipe is connected to the output port of the pressurized water pump through a first connecting flexible pipe, and the first connecting rigid pipe is connected to the spray plate through a second connecting flexible pipe. The combination of the first connecting rigid pipe, the first connecting flexible pipe, and the second connecting flexible pipe achieves a balance between rigid support and flexible compensation. The first connecting rigid pipe, fixed on the movable second base, provides the main support frame for the pipeline. The first and second connecting flexible pipes effectively absorb the relative displacement and deflection generated when the second base moves and the angle adjustment component operates, preventing the pipeline from being subjected to excessive stress and fatigue damage, thus ensuring the reliability and sealing of the water supply line under continuous pressurization operation of the water pump.

[0011] A further improvement of this utility model is that a first explosion-proof spring is fitted around the outside of the first connecting hose, and a second explosion-proof spring is fitted around the outside of the second connecting hose. The explosion-proof spring can withstand accidental mechanical impacts such as collisions, scratches, and squeezing that may occur in the working environment, preventing damage to the outer layer of the hose; more importantly, when the pressure of the medium inside the hose rises abnormally, the spring structure can restrain and limit the expansion of the hose, greatly reducing the risk of hose rupture and improving the safety of the device in high-pressure working environments.

[0012] A further improvement of this utility model is that an air compressor is provided on one side of the aforementioned pressurized water pump, and the air compressor, the pressurized water pump, and the first connecting hose are connected by a T-junction rigid pipe. The installation of the air compressor and its connection to the pressurized water pump via the T-junction rigid pipe enables convenient mixing and coordinated operation of air and water media; through the T-junction rigid pipe, compressed air can be introduced into the water flow as needed to form an air-water mixed jet flow; this mixed flow combines the high-speed kinetic energy of gas with the wetting and condensing effects of water, which can more effectively remove dirt and simultaneously suppress dust during cleaning, improving cleaning efficiency and environmental performance.

[0013] A further improvement of this invention is that the aforementioned spray plate is connected to a second connecting hose via a second connecting rigid pipe, with one end of the second connecting rigid pipe extending to the outside of the support platform away from the spray plate. This structure optimizes the pipeline layout, improving reliability and aesthetics; it also reduces wear contact between the support platform and the second connecting hose, facilitating daily inspection and maintenance, and enhancing the overall structural compactness of the equipment.

[0014] As can be seen from the above technical solutions, the beneficial effects of this utility model are: combining the spray washing plate with the angle adjustment component and setting it as a whole on the second base that can slide along the track, it achieves a high degree of flexibility and wide coverage of the cleaning operation; the angle adjustment component allows the washing direction of the spray washing plate to be adjusted in real time according to the structure of the carriage, thereby effectively dealing with complex contours such as side walls, end walls and roof edges; and the characteristic of the second base moving along the track allows the device to move along the length of the carriage, realizing continuous and thorough cleaning of the entire inner wall of the carriage, solving the problem of many blind spots in fixed equipment.

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] like Figures 1-4 As shown, this utility model discloses a high-pressure cleaning device for train carriages, including a first base 6. A water tank 2, a pressurized water pump 4, and an air compressor 3 are mounted on the first base 6. The output port of the water tank 2 is connected to the pressurized water pump 4. The air compressor 3 is located on one side of the pressurized water pump 4. The air compressor 3, the pressurized water pump 4, and the first connecting hose 7 are connected by a T-junction rigid pipe 5. The T-junction rigid pipe 5 connects to a spray plate 13, on which nozzles 14 are evenly distributed. The air compressor 3 and its connection to the pressurized water pump 4 via the T-junction rigid pipe 5 facilitate convenient mixing and coordinated operation of air and water media. Through the T-junction rigid pipe 5, compressed air can be introduced into the water flow as needed to form a mixed air-water jet stream. This mixed stream combines the high-speed kinetic energy of gas with the wetting and condensing effects of water, effectively removing dirt and suppressing dust during cleaning, thus improving cleaning efficiency and environmental performance. Of course, the operation of the pressurized water pump 4 and the air compressor 3 can also be controlled separately, so as to select the state of jetting, water spraying or water mist containing aerosols according to different needs. Among them, the state of water mist containing aerosols combines the high-speed jetting of water flow with the breaking effect of gas after contact with the surface of the object, which can accelerate the cleaning intensity of impurities on the carriage.

[0023] The first base 6 is also equipped with a control cabinet 1 that can control the pressurized water pump 4, the air compressor 3 and the angle adjustment component 18. The start-up control of the above-mentioned functional components can be realized by operating the control cabinet 1.

[0024] The water tank 2 has a capacity of ≥50L, the pressurized water pump 4 has a power of 1-2kW and an output pressure of 0.2-0.4MPa; the nozzle 14 adopts a swirling or ultrasonic structure to atomize water into fine water droplets with a particle size of ≤100μm; the mist water and high-pressure gas mix in the nozzle 14 or at the outlet to form a "gas-mist synergistic flow", which not only suppresses dust, but also softens stubborn dirt and improves the cleaning effect.

[0025] The air compressor 3 is a 7.5kW screw air compressor with an output pressure of 0.8MPa; the water tank 2 is 60L; the pressurized water pump 4 is a 1.5kW plunger pump; the nozzle 14 has an orifice diameter of 0.3mm; and the spray plate 13 has a height of 4m.

[0026] For a standard C70 open wagon (13.9m long, 3.1m wide, and 2.9m high), the system automatically completed the cleaning of the entire wagon compartment in an average time of 2 minutes, achieving a cleaning rate of 96%. No personnel entered the wagon compartment during the operation, and the dust concentration decreased from 15mg / m³ to 1.2mg / m³. 3 .

[0027] The spray surface of the spray plate 13 has an obtuse angle structure in the vertical plane; the nozzles 14 are evenly distributed on the spray surface of the spray plate 13. This helps to improve the coverage area and impact effect of the rinsing flow; the obtuse angle structure allows the high-speed medium ejected from the nozzles 14 to naturally form a certain diffusion angle in space, so that a single rinse can cover a wider strip area; at the same time, this structure helps to concentrate the impact force in a more effective direction, which is beneficial for removing stubborn deposits and avoids uneven cleaning effect.

[0028] An angle adjustment component 18 is provided on one side of the spray plate 13. The angle adjustment component 18 is connected to the spray plate 13 and adjusts the rinsing direction of the spray plate 13. The angle adjustment component 18 is mounted on the second base 9 via a support platform 11. The second base 9 is slidably mounted on the track 17 via wheels. With the cooperation of the angle adjustment component 18 and the movement of the second base 9 along the track 17, the spray plate 13 helps to increase the cleaning area applied to the carriage, provide targeted treatment for corners, and achieve structural optimization while reducing the floor space occupied.

[0029] The angle adjustment component 18 is mounted on the second base 9 via a support platform 11. The support platform 11 helps to increase the installation height of the angle adjustment component 18, thereby optimizing the optimal rotation height of the spray wash plate 13 and achieving adaptation to the carriage.

[0030] The angle adjustment assembly 18 includes a support arm 1802, an adjusting arm 1801, and a telescopic cylinder 1803. The support arm 1802 is vertically mounted on the second base 9. The adjusting arm 1801 is hinged to the top of the support arm 1802. One end of the adjusting arm 1801 is connected to the spray plate 13, and the other end is hinged to the telescopic cylinder 1803. One end of the telescopic cylinder 1803 is connected to the adjusting arm 1801, and the other end is connected to the second base 9. With the cooperation of the support arm 1802, the rotation stability of the adjusting arm 1801 is achieved, thereby controlling the pitch angle of the spray plate 13. While covering corner areas, the cleaning power is enhanced by the tilted cleaning direction.

[0031] Specifically, the support arm 1802 and the telescopic cylinder 1803 are mounted on the support platform 11.

[0032] A first connecting rigid pipe 10 is fixedly installed on the second base 9. One end of the first connecting rigid pipe 10 is connected to the output port of the pressurized water pump 4 through a first connecting flexible hose 7. Specifically, the first connecting flexible hose 7 is connected to the end of the tee rigid pipe 5. The first connecting rigid pipe 10 is connected to the spray plate 13 through a second connecting flexible hose 16. The combination of the first connecting rigid pipe 10, the first connecting flexible hose 7, and the second connecting flexible hose 16 has the technical advantage of achieving a balance between rigid support and flexible compensation. The first connecting rigid pipe 10 is fixed on the movable second base 9, providing the main support frame for the pipeline. The first connecting flexible hose 7 and the second connecting flexible hose 16 effectively absorb the relative displacement and deflection generated when the second base 9 moves and the angle adjustment component 18 moves, preventing the pipeline from being subjected to excessive stress and fatigue damage, and ensuring the reliability and sealing of the water supply line under continuous pressurization operation of the water pump.

[0033] The spray plate 13 is connected to the second connecting hose 16 via a second connecting rigid pipe 12, with one end of the second connecting rigid pipe 12 extending to the outside of the support platform 11 away from the spray plate 13. This structure optimizes the pipeline layout, improves reliability and aesthetics, reduces wear contact between the support platform 11 and the second connecting hose 16, facilitates daily inspection and maintenance, and enhances the overall structural compactness of the equipment.

[0034] The first connecting hose 7 is fitted with a first explosion-proof spring 8; the second connecting hose 16 is fitted with a second explosion-proof spring 15. The explosion-proof springs can withstand accidental mechanical impacts such as collisions, scratches, and squeezing that may occur in the working environment, preventing damage to the outer layer of the hose; more importantly, when the pressure of the medium inside the hose rises abnormally, the spring structure can restrain and limit the expansion of the hose, greatly reducing the risk of hose rupture and improving the safety of the device in high-pressure working environments.

[0035] Anti-collision sensors, high-definition cameras, and laser positioning modules can also be installed on the spray cleaning plate 13 to automatically identify the outline of the carriage, obstacles, and target areas, achieving precise positioning. To complement this structure, a PLC controller, human-machine interface (HMI), remote control terminal, and sensor group (including position sensor, pressure sensor, and dust concentration sensor) need to be added to the control cabinet 1. The system has multiple preset cleaning modes (such as "full carriage mode" and "coupler-specific mode"), supporting automatic / manual switching. During operation, the PLC automatically starts the spray cleaning plate 13 for positioning based on the carriage arrival signal, first using high-pressure gas to blow clean, and then synchronously or with a delay to start atomized water spraying. When personnel are detected entering the work area, the safety interlock mechanism immediately cuts off power and stops the machine.

[0036] The nozzle 14 integrates a high-pressure gas nozzle and an atomizing nozzle, with the outlet distance between the two controlled within the range of 5-20mm. This ensures that the high-speed airflow (wind speed ≥50 m / s) and the fine water mist (particle size ≤100μm) mix immediately after leaving the nozzle 14, forming a "gas-mist impact flow" with high kinetic energy and high wettability. This mixed flow can penetrate deep into complex structures such as gaps in the carriage and grooves in the coupler, effectively stripping away adhering materials.

[0037] Fine water mist has an extremely large specific surface area, enabling it to collide, adsorb, and agglomerate with suspended dust particles in the air, increasing their mass and causing them to settle rapidly. Experiments show that when the water mist particle size is controlled between 10 and 100 μm, the collection efficiency for PM10 and PM2.5 dust can reach over 90%. Simultaneously, the water mist covering the vehicle's surface can pre-wet residual materials, reducing the likelihood of them being stirred up by airflow, thus achieving "dust suppression at the source."

[0038] Compared to traditional high-pressure water jet cleaning (consuming 50-100L of water per wash), this device only requires 5-10L of water to suppress dust throughout the entire cargo compartment, and generates no wastewater. The water mist evaporates quickly after dust suppression, without affecting subsequent loading operations, making it especially suitable for bulk cargo that is sensitive to moisture content (such as coal, fertilizer, and grain).

[0039] Without water mist, high-pressure gas cleaning causes the dust concentration in the work area to spike to over 20 mg / m³ instantly; after activating the aerosol synergy mode, the dust concentration is stably controlled below 1.5 mg / m³.

[0040] The high-pressure cleaning device for train carriages described in this utility model combines a spray plate with an angle adjustment component and is integrally mounted on a second base that can slide along the track, achieving high flexibility and wide coverage in cleaning operations. The angle adjustment component allows the spray plate to be adjusted in real time according to the carriage structure, effectively addressing complex contours such as side walls, end walls, and roof edges. The second base's ability to move along the track allows the device to travel along the length of the carriage, achieving continuous, thorough cleaning of the entire carriage interior, thus solving the problem of numerous blind spots in fixed equipment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
