Description

Technical Field

[0001] This application relates to the field of train carriage cleaning, and mainly to a train carriage residual coal cleaning device. Background Technology

[0002] As a vital energy resource in my country, efficient and clean operation of coal transportation via railway is crucial. After unloading coal, a large amount of residual coal remains on the walls and bottom of the train carriages. Traditional manual cleaning methods are not only inefficient and costly, but also pose safety hazards due to working at heights and cause environmental pollution from coal dust. These methods are no longer suitable for the development needs of modern green and intelligent logistics.

[0003] To replace manual labor, the industry has successively developed various mechanized cleaning equipment. Early technologies mostly used high-pressure nozzle flushing or simple robotic arm scraping, which, while achieving functional replacement to some extent, generally suffered from problems such as excessive energy consumption, poor adaptability to complex carriage structures, incomplete cleaning, and easy damage to the carriage interior walls. Subsequent improved technologies introduced negative pressure adsorption and gravity settling systems to reduce dust, but often due to unreasonable structural layout, the cleaning module and suction module interfered with each other, resulting in poor system coordination and bottlenecks in overall operating efficiency.

[0004] Further intelligent upgrades focus on introducing visual monitoring and automated control. However, existing equipment still has significant shortcomings in terms of perception accuracy, decision-making intelligence, and execution adaptability. For example, the lack of accurate perception of the three-dimensional contours of the carriage means that the equipment cannot adapt to the size changes of different vehicle models, posing a collision risk; fixed cleaning parameters cannot be dynamically adjusted according to the distribution of residual coal, resulting in energy waste and cleaning blind spots.

[0005] In conclusion, developing a railway car coal cleaning device that integrates intelligent sensing, adaptive cleaning, efficient dust removal, and residual coal recovery, and can adapt to complex working conditions, is of great practical significance for overcoming existing technological bottlenecks. This will not only completely free up manpower and eliminate safety hazards, achieving efficient recovery of residual coal from the cars, but also significantly improve train turnaround efficiency, driving the coal transportation industry towards full automation, greening, and intelligentization. Utility Model Content

[0006] In view of the technical problems of low efficiency and poor safety of manual operation in the existing technology, and the lack of adaptability and difficulty in dust control of mechanical equipment, this application proposes a coal cleaning device for train carriages to solve the above problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A coal cleaning device for train carriages includes a guide truss, a lifting unit, and a cleaning and dust extraction coordinating unit; The lifting unit is mounted on the guide truss, and the main frame of the sweeping and vacuuming coordination unit is connected to the lifting unit; The cleaning and vacuuming collaborative unit includes a cleaning component and a vacuuming component; The cleaning assembly includes a roller brush, side brushes, and a top brush. The roller brush is located at the bottom of the main frame of the cleaning and vacuuming unit, with its axis perpendicular to the length of the train car and adapted to the train car floor. The side brushes are symmetrically distributed along the axis of the roller brush on both outer sides. The top brush is located below the side beams of the guide truss and corresponds to the top of both side walls of the train car, with its axis aligned with that of the roller brush. The dust collection assembly includes a dual vacuum negative pressure dust collection device, a multi-stage dust collection and filtration device, and a built-in dust collection box.

[0008] The train car coal cleaning device provided in this application achieves comprehensive, no-dead-angle mechanized cleaning of the train car floor, corners, and top through the coordinated operation of the guide truss, lifting unit, and cleaning and dust collection unit. The rational layout of the roller brush, side brush, and top brush effectively removes coal residue from different locations, while the dual-vacuum negative pressure dust collection device and multi-layer filtration system simultaneously achieve dust adsorption and material collection during the cleaning process, significantly improving cleaning efficiency and cleanliness, effectively suppressing dust dispersion, improving the working environment, and greatly reducing the safety risks and labor intensity of manual cleaning.

[0009] Preferably, the guide truss extends along the length of the train car and is equipped with a travel drive mechanism. The travel drive mechanism of the guide truss adopts a combination of motor drive and gear transmission, which has stable and reliable travel capability.

[0010] Preferably, the lifting unit is a hydraulic drive mechanism, which is equipped with an anti-fall device and an oil pipe explosion-proof device. The hydraulic drive structure has the advantages of smooth lifting and high load-bearing capacity, and can stably drive the sweeping and vacuuming auxiliary unit to adapt to different heights of the vehicle body.

[0011] Preferably, the side brush is equipped with a hydraulic adjustment mechanism for adjusting the distance between the side brush and the inner wall of the train carriage. The hydraulic adjustment mechanism can precisely adjust the distance between the side brush and the inner wall of the carriage according to the actual width of the carriage, ensuring that the side brush always performs cleaning operations with optimal pressure and position. This guarantees the cleaning effect while avoiding excessive wear of the side brush or incomplete cleaning due to improper spacing, greatly improving the adaptability and durability of the equipment.

[0012] Preferably, the top brush is mounted below the side beam of the guide truss via a lateral adjustment slide rail assembly. The lateral adjustment slide rail assembly includes a fixed slide rail and a sliding seat. The fixed slide rail extends along the width direction of the guide truss and is fixedly connected to the side beam of the guide truss. The sliding seat is slidably engaged with the fixed slide rail, and the top brush is fixedly connected to the sliding seat. This design of the lateral adjustment slide rail assembly allows the top brush to be laterally adjusted according to the actual position of the top of the carriage side wall.

[0013] Preferably, the suction port of the dual vacuum negative pressure dust collection device is located on the front side of the roller brush and on the rear side of the side brush. This design ensures that while the roller brush and side brush are cleaning up residual coal, the dual vacuum negative pressure dust collection device can immediately suck up the raised coal dust and scattered residual coal, preventing coal dust from spreading inside the carriage.

[0014] Preferably, the multi-stage dust collection and filtration device is equipped with a pulse automatic dust removal mechanism. When the coal dust adhering to the surface of the filter device reaches a certain thickness, the pulse automatic dust removal mechanism will be activated, using high-pressure gas pulses to shake off the coal dust from the filter device and cause it to fall into the built-in dust collection box.

[0015] Preferably, the built-in dust collection box is disposed within the main frame of the sweeping and dust collection co-processing unit, the bottom of the built-in dust collection box is provided with a discharge port, and the built-in dust collection box is provided with a guide slope inclined towards the discharge port.

[0016] More preferably, the dust collection assembly further includes a multi-functional storage hopper, and an RGV transfer vehicle or conveyor line is configured between the multi-functional storage hopper and the built-in dust collection box. When a certain amount of residual coal is collected in the built-in dust collection box, the residual coal can be transferred to the multi-functional storage hopper for centralized storage via the RGV transfer vehicle or conveyor line.

[0017] Preferably, the train carriage coal cleaning device further includes a vision unit, which comprises a high-definition industrial camera and a laser rangefinder. The high-definition industrial camera is mounted at the front end of the main frame of the cleaning and dust collection co-processing unit; the laser rangefinder is mounted on both sides of the main frame of the cleaning and dust collection co-processing unit. The vision unit can provide real-time image information such as the distribution of residual coal inside the carriage, the cleanliness of the carriage walls, the distance between the cleaning and dust collection co-processing unit and the carriage walls, and the carriage's dimensional parameters.

[0018] Compared with the prior art, this application has the following beneficial effects: (1) The train car coal cleaning device of this application constructs a three-dimensional cleaning system through the multi-brush combination design of roller brush, side brush and top brush, realizing all-round cleaning inside the car and significantly improving the thoroughness and work efficiency of a single cleaning. (2) The coal cleaning device for train carriages in this application uses a double vacuum negative pressure dust collection device in conjunction with a multi-stage layer filtration device to achieve immediate and efficient capture and treatment of coal dust, which fundamentally solves the problem of dust pollution during operation, greatly improves the working environment, and meets the requirements of green environmental protection. (3) The train car coal cleaning device of this application is designed with a variety of adjustment mechanisms, which enable the equipment to flexibly adjust the position and angle of the cleaning components, thereby adapting to the differences in width and internal structure of different types of train cars, and solving the problems of poor adaptability and easy damage to the inner wall of the car of the existing equipment; (4) The train car coal cleaning device of this application achieves mechanized operation through the movement of the guide truss, the lifting unit lifting, and the coordinated operation of each brush during the entire cleaning process, without the need for direct human intervention. At the same time, the safety mechanisms such as anti-fall and explosion-proof integrated into the device further ensure the safety and reliability of the equipment itself. (5) The coal cleaning device for train carriages of this application has a built-in dust collection box, which is compact in structure.

Detailed Implementation

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0022] Where there is no conflict, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Figure 1 and Figure 2 The diagrams show the overall structure and installation of a coal cleaning device for train carriages. (For reference) Figure 1 and Figure 2 The coal cleaning device for the train carriage includes a guide truss 1, a lifting unit 2, and a cleaning and dust extraction coordinating unit. The lifting unit 2 is installed on the guide truss 1, and the main frame 3 of the cleaning and dust extraction coordinating unit is connected to the lifting unit 2.

[0024] Specifically, the guide truss 1 extends along the length of the train carriage 4, and the guide truss 1 is equipped with a walking drive mechanism. The walking drive mechanism adopts a combination of motor drive and gear transmission to provide stable and reliable walking power for the device, enabling it to move smoothly along the length of the train carriage 4 and ensuring that the cleaning operation can cover the entire carriage.

[0025] Specifically, the lifting unit 2 is a hydraulically driven mechanism, which provides smooth lifting and strong load-bearing capacity. It is also equipped with an anti-fall device and an oil pipe explosion-proof device. The anti-fall device can quickly take effect when the hydraulic system loses pressure, preventing the cleaning and dust collection unit from falling accidentally and ensuring the safety of equipment and personnel. The oil pipe explosion-proof device can prevent hydraulic oil leakage and equipment failure caused by oil pipe rupture, significantly improving the safety of equipment operation and reducing the risk of accidents.

[0026] Specifically, the cleaning and vacuuming co-processing unit includes a cleaning component and a vacuuming component. The cleaning component includes a roller brush 31, a side brush 32, and a top brush 33. The vacuuming component includes a dual vacuum negative pressure vacuuming device 34, a multi-stage vacuuming filtration device 35, and a built-in dust collection box 36.

[0027] In a specific embodiment, the roller brush 31 is located at the bottom of the main frame 3 of the cleaning and dust collection unit, with its axis perpendicular to the length of the train carriage 4 and adapted to the bottom plate of the train carriage 4, which can effectively remove residual coal from the bottom plate of the carriage.

[0028] In a specific embodiment, the side brushes 32 are symmetrically distributed on the outer sides of both ends of the roller brush 31 along the axis of the roller brush 31, and are equipped with a hydraulic adjustment mechanism 38 for adjusting the distance between the side brushes and the inner wall of the train car. The hydraulic adjustment mechanism 38 can precisely adjust the distance between the side brushes and the inner wall of the train car according to the actual width of the train car 4, ensuring that the side brushes 32 always perform cleaning operations with the best pressure and position. This not only ensures the cleaning effect, but also avoids the problem of excessive wear of the side brushes or incomplete cleaning caused by improper spacing, greatly improving the adaptability and durability of the equipment.

[0029] In a specific embodiment, the top brush 33 is positioned below the side beam of the guide truss 1 and corresponds to the top of both side walls of the train car 4, with its axial direction aligned with that of the roller brush 31. The top brush 33 is installed below the side beam of the guide truss 1 via a lateral adjustment slide rail assembly. This assembly consists of a fixed slide rail and a sliding seat. The fixed slide rail extends along the width of the guide truss 1 and is fixedly connected to the side beam of the guide truss 1. The sliding seat slides in conjunction with the fixed slide rail, and the top brush 33 is fixedly connected to the sliding seat. This design allows the sliding seat to slide flexibly on the fixed slide rail when dealing with cars of different widths, thereby changing the lateral position of the top brush 33. This ensures that the top brush 33 always accurately reaches the residual coal area on the top of the side wall of the car, achieving comprehensive and efficient cleaning and further enhancing the adaptability of the cleaning device to different car models.

[0030] Figure 3 and Figure 4 These are the front view and the AA section view of the coal cleaning device for the train carriage, respectively. (Continue to refer to...) Figure 3 and Figure 4 .

[0031] In a specific embodiment, the suction port of the dual vacuum negative pressure dust collection device 34 is located on the front side of the roller brush 31 and on the rear side of the side brush 32. When the roller brush 31 and the side brush 32 raise the residual coal on the floor of the train car 4 during the cleaning process, the dual vacuum negative pressure dust collection device 34 can use its powerful negative pressure suction to suck up the raised coal dust and scattered residual coal through the suction port immediately. This design effectively avoids the spread of coal dust in the car and reduces the impact of secondary dust on the working environment and personnel health. At the same time, the close cooperation between the dual vacuum negative pressure dust collection device 34, the roller brush 31, and the side brush 32 enables simultaneous cleaning and dust collection, greatly improving cleaning efficiency and allowing the interior of the car to quickly return to a clean state.

[0032] In a specific embodiment, the multi-stage dust collection and filtration device 35 is equipped with a pulse automatic dust removal mechanism 37. During the dust collection process, coal dust enters the multi-stage dust collection and filtration device 35 with the airflow and adheres to its surface. As the filtration time increases, the coal dust adhering to the surface of the multi-stage dust collection and filtration device 35 gradually thickens, which affects the dust collection effect and air circulation of the device. At this time, the pulse automatic dust removal mechanism 37 will be activated in time, using high-pressure gas pulses to shake off the coal dust on the multi-stage dust collection and filtration device 35. The shaken-off coal dust will fall into the built-in dust collection box 36 below, thereby realizing the automatic cleaning of the multi-stage dust collection and filtration device 35, ensuring that the multi-stage dust collection and filtration device 35 always maintains good filtration performance, and ensuring the continuous and efficient operation of the dust collection process.

[0033] In a specific embodiment, the built-in dust collection box 36 is housed within the main frame 3 of the sweeping and dust collection co-processing unit. It has a discharge port at its bottom, and the interior of the built-in dust collection box 36 features a guide slope inclined towards the discharge port. This design allows coal dust falling into the built-in dust collection box 36 to naturally slide down the guide slope to the discharge port, preventing dust accumulation in dead corners and facilitating subsequent smooth discharge. Once a certain amount of residual coal is collected in the built-in dust collection box 36, it can be transferred from the discharge port to a multi-functional storage silo for centralized storage via a configured RGV transfer vehicle or conveyor line. This automated transfer method not only improves work efficiency but also reduces the inconvenience and potential risks associated with manual operation, providing a strong guarantee for the smooth operation of the entire sweeping process.

[0034] Specifically, the train carriage coal cleaning device also includes a vision unit, which comprises a high-definition industrial camera and a laser rangefinder. The high-definition industrial camera is installed at the front end of the main frame 3 of the cleaning and dust collection unit, enabling it to clearly capture key image information such as the distribution of residual coal inside the carriage and the cleanliness of the carriage walls. The laser rangefinder is installed on both sides of the main frame 3 of the cleaning and dust collection unit, accurately measuring the distance between the cleaning and dust collection unit and the carriage walls, as well as important data such as the carriage's dimensions. Through the collaborative work of the high-definition industrial camera and the laser rangefinder, the vision unit provides the cleaning device with comprehensive and accurate environmental perception capabilities. The image information captured by the high-definition industrial camera, after image processing analysis, provides precise basis for cleaning operations, determining which areas require focused cleaning and which areas have already met cleaning standards. The data acquired by the laser rangefinder allows the device to adjust the position and cleaning parameters of the cleaning components in real time, ensuring adaptive cleaning under different train models and different residual coal distribution conditions, further improving the intelligence level and cleaning effect of the cleaning device.

[0035] In other embodiments, the train car coal cleaning device also includes a control unit and a remote operation unit.

[0036] Specifically, the control unit is electrically connected to the vision unit, guide truss 1, lifting unit 2, sweeping assembly, and vacuuming assembly, and is communicatively connected to the remote operation unit. The control unit can receive signals from the vision unit, various sensors, and the remote operation unit, and precisely control the movement of the guide truss, the lifting of the lifting unit, the operation of the sweeping assembly, and the operation of the vacuuming assembly according to preset programs and algorithms.

[0037] Specifically, the remote operation unit provides users with convenient remote monitoring and operation capabilities. Through a wireless network, operators can monitor and operate the cleaning device in real time from a control room far from the work site, using a computer or dedicated operating terminal. The remote operation unit features an intuitive human-machine interface that displays the real-time operating status of the cleaning device, the working parameters of each component, and the cleaning status within the vehicle compartment. Based on this information, operators can issue commands to start, stop, and adjust cleaning parameters at any time, achieving precise remote control of the cleaning device. This remote operation method not only improves operational flexibility and safety but also allows operators to manage the cleaning device in a more comfortable environment, making it particularly suitable for harsh working conditions.
