Abstract
Description
Technical Field
[0001] This application relates to the field of rail transit facility maintenance technology, specifically to a separate sweeping and suction device and a railway track bed vacuum truck. Background Technology
[0002] Due to its reliability and large carrying capacity, rail transit is not only used for people's travel, but also for freight transportation, such as coal, which is mainly transported by rail transit.
[0003] Currently, the coal trains used on dedicated railway coal transport lines all have open roof structures. When these trains enter or exit tunnels, and when vehicles pass each other within the tunnels, the resulting airflow turbulence can blow coal dust and some coal chunks out of the carriages and scatter them on the track surface inside the tunnel. The coal dust kicked up by the passing trains can severely impair the train driver's visibility. When the coal dust and coal chunks accumulate to a thick layer, they can bury the rails, sleepers, track spikes, fasteners, and electrical equipment, making maintenance impossible and endangering train safety.
[0004] Currently, mechanical devices for collecting loose coal dust and lumps have a fixed cleaning cross-section, resulting in a narrow range of application. They are only suitable for specific lines and cannot be universally applied. However, in practical applications, due to the different types of sleepers used in coal transport tunnels, the distribution of loose coal dust varies. On some lines, coal dust is distributed across the entire track surface, on others it is concentrated in the middle, while on some lines (such as the Datong-Qinhuangdao Railway), there is almost no coal dust in the middle of the rails. Existing vacuum trucks' sweeping and suction devices cannot be adapted to all sleeper types because their cleaning range cannot be changed. They are inefficient on unsuitable lines, necessitating the design of different cleaning devices for different line types. This results in high R&D costs, long development cycles, and incompatible components among various cleaning devices, leading to high maintenance costs. Summary of the Invention
[0005] To address one of the aforementioned technical deficiencies, this application provides a separate sweeping and suction device and a railway track bed vacuum truck using such a sweeping and suction separation device.
[0006] According to a first aspect of the embodiments of this application, a detachable sweeping and suction device is provided, comprising at least two sets of sweeping and suction assemblies, each set of sweeping and suction assemblies comprising a sweeping and suction assembly frame, a cleaning component and a suction component, the cleaning component and the suction component being mounted on the sweeping and suction assembly frame; a sweeping and suction assembly separation device, connected to the sweeping and suction assemblies and used to drive the two sets of sweeping and suction assemblies to move relative to or away from each other to change the cleaning range; and a swinging suction tube, one end of which is connected to the suction component of the sweeping and suction assembly, and the swinging suction tube can swing along with the movement of the sweeping and suction assemblies.
[0007] According to a second aspect of the embodiments of this application, a railway track bed vacuum truck is provided, including the detachable sweeping and suction device as described above.
[0008] The separate sweeping and suction device provided in this application embodiment can be used to clean all types of rails, as well as in environments where there are no rails and cleaning is required. The separate sweeping and suction device provided in this application embodiment has two sets of sweeping and suction components. These two sets of sweeping and suction components can be arranged side by side in the longitudinal direction. They can be brought together to clean the middle part of the rail, or they can be separated laterally to clean both sides of the rail. The lateral movement distance can be adjusted as needed.

[0021] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0022] In the process of developing this application, the inventors discovered that the current domestic mechanical collection devices for loose coal dust and coal lumps have a fixed cleaning section, are only applicable to specific lines, and are not universal. They are not efficient for unsuitable lines, which means that different cleaning devices need to be designed according to different line types. The research and development costs are high and the cycle is long. In addition, the components of various cleaning devices are not universal, and the maintenance costs are also very high.
[0023] To address the aforementioned issues, this application provides a separate sweeping and suction device, and specifically illustrates its application on a sewage suction truck for railway track bed.
[0024] In this embodiment of the application, the length direction of the railway track vacuum truck, which is also the direction of track extension, is called longitudinal, the width direction is called transverse, the height direction is called vertical, the direction towards the running direction of the railway track vacuum truck is called front, the direction towards the opposite direction of the running direction of the railway track vacuum truck is called rear, the direction towards the central axis of the track is called inward, and the opposite direction is called outward.
[0025] Figure 1 and Figure 2 All of these are schematic diagrams of the separate sweeping and suction device provided in this application. Figure 1 It is in the closed state. Figure 2It is a separated state, such as Figure 1 The illustrated detachable sweeping and suction device includes two sets of sweeping and suction assemblies 131, two sets of sweeping and suction assembly separation devices 132, and two swinging suction tubes 133. Each set of sweeping and suction assemblies 131 includes a sweeping and suction assembly frame 1311, a cleaning component, and a suction component, which are mounted on the sweeping and suction assembly frame 1311. The sweeping and suction assembly separation device 132 is connected to the sweeping and suction assembly 131 and is used to drive the two sets of sweeping and suction assemblies 131 to move relative to or away from each other to change the cleaning range. One end of each swinging suction tube 133 is connected to the suction component of one set of sweeping and suction assemblies 131, and the swinging suction tube 133 can swing along with the movement of the sweeping and suction assembly 131.
[0026] The sweeping and suction assembly 131 is responsible for sweeping up the ballast on the track bed and sucking it up through negative pressure. The sweeping and suction assembly separation device 132 drives the sweeping and suction assembly 131 to rise, fall, or move horizontally within its working plane according to the operator's instructions. When the area to be cleaned is in the middle of the rail or the cleaning width is small, the two sets of sweeping and suction assemblies 131 close together. Figure 1 As shown, when the area to be cleaned is on both sides of the railway track or the cleaning width is wide, the two sets of sweeping and suction components 131 separate as shown. Figure 2 The operation is as shown. The separation width between the two sets of sweeping and suction components 131 can be adjusted according to the actual track type. Therefore, the sewage suction truck using the separate sweeping and suction device of this application embodiment has strong versatility, cleans thoroughly, covers a wider range, has better track applicability, and higher utilization rate of the working device. The swing suction pipe 133 is used to transport the ballast sucked in by the sweeping and suction components 131 to the subsequent processing device. The swing suction pipe 133 swings with the sweeping and suction components 131, which can reduce the transport resistance of ballast such as coal powder in the pipeline and improve the operating efficiency.
[0027] This application provides a specific implementation of a sweeping and suction component separation device. Figure 3 This is a schematic diagram of the structure of the sweeping and suction component separation device provided in the embodiments of this application, as shown below. Figure 3 As shown, the sweeping and suction component separation device 132 includes a lateral moving component and a lifting component. The lifting component is connected to the lateral moving component, and the sweeping and suction component 131 is connected to the lifting component. The lifting component drives the sweeping and suction component 131 to move up and down in the vertical direction, and the lateral moving component drives the lifting component and the sweeping and suction component 131 to move laterally.
[0028] Furthermore, the lateral movement assembly includes a fixed beam 1321, a movable beam 1322, and a movement drive component. The fixed beam 1321 is a hollow structure, the movable beam 1322 is nested within the fixed beam 1321, and the movement drive component is mounted on the movable beam 1322 and can drive the movable beam 1322 to slide in or out of the fixed beam 1321. The lateral movement assembly is used to adjust the size of the cleaning cross-section of the sweeping and suction assembly 131 to accommodate the needs of different gauge rails. The movement drive component is specifically a movable hydraulic cylinder 1323.
[0029] Furthermore, the lifting assembly includes a hollow fixed base 1324, a lifting column 1325, and a lifting drive component. The fixed base 1324 is vertically fixed to the moving beam 1322. The lifting column 1325 is nested within the fixed base 1324. The lifting drive component is mounted on the lifting column 1325 and can drive the lifting column 1325 to slide up and down within the fixed base 1324. The sweeping and suction assembly 131 is fixed to the bottom end of the lifting column 1325. The lifting assembly is used to adjust the height of the sweeping and suction assembly 131. When not in operation, it is raised to protect the device; when in operation, it is lowered to the working plane for easy operation. The lifting drive component is specifically a lifting cylinder 1326.
[0030] The movable cylinder 1323 and the lifting cylinder 1326 can be replaced by mechanical components with similar functions, such as cylinders, gear racks, worm gears, etc., which will not be elaborated here.
[0031] This application also provides a specific implementation method for the sweeping and suction component 131. Figure 4 This is a schematic diagram of the structure of the sweeping and suction assembly provided in the embodiments of this application, as shown below. Figure 4 As shown, the cleaning component is a roller brush 1312, of which there are two sets, rotatably mounted on the sweeping and suction assembly frame 1311. The two sets of roller brushes 1312 are arranged parallel to each other. The suction component is a suction hood 1313, which is installed between the two sets of roller brushes 1312. The lower end of the suction hood 1313 is the suction opening, and the upper end passes through the sweeping and suction assembly frame 1311 and is connected to the swing suction pipe 133. Each roller brush 1312 has a rotating shaft, which is rotatably mounted on the sweeping and suction assembly frame 1311 via a bearing seat 1314. A roller brush drive device 1315 is mounted on the roller brush rotating shaft outside the bearing seat 1314. In some specific embodiments, the roller brush drive device 1315 is a drive motor. During operation, the roller brush drive device 1315 drives two sets of roller brushes 1312 to rotate, raising the sludge and sucking it into the swing suction pipe 133 through the suction hood 1313.
[0032] Furthermore, the suction hood 1313 adopts a double-layer structure consisting of an inner and an outer opening. That is, a certain width gap is provided between the inner and outer openings of the suction hood 1313. This gap allows for supplemental airflow to the suction hood, preventing coal dust and other pollutants from accumulating and clogging the openings, thus affecting suction efficiency. A guide plate is installed below the suction hood opening. The central plane of the suction hood 1313 is at a certain angle to the vertical direction, making it easier for coal dust swept by the roller brush to enter the suction hood.
[0033] To further improve work efficiency, in some preferred embodiments, a swingable suction hood 1313 is adopted. Figure 5 This is a schematic diagram of the structure of the suction hood provided in the embodiments of this application, as shown below. Figure 5 As shown, the suction hood 1313 is equipped with a suction hood swinging device that propels the suction hood 1313 to swing between two sets of roller brushes 1312. The suction hood swinging device includes a suction hood driving component 1316, a suction hood swing shaft 1317, and a suction hood swing shaft connector 1318. The suction hood swing shaft connector 1318 is fixed to the outer wall of the suction hood 1313. One end of the suction hood swing shaft 1317 is rotatably connected to the suction hood swing shaft connector 1318 via a bearing. The other end of the suction hood swing shaft 1317 is connected to the suction hood driving component 1316. The suction hood driving component 1316 is fixed on the sweeping and suction assembly frame 1311 and can drive the suction hood swing shaft 1317 to rotate. In some specific embodiments, the suction hood driving component 1316 is a hydraulic cylinder. In other specific embodiments, a pneumatic cylinder is used. The cylinder body of the hydraulic cylinder or pneumatic cylinder is fixed on the sweeping and suction assembly frame 1311, and one end of the piston is rotatably connected to the suction hood swing shaft 1317. The extension and retraction of the piston drives the suction hood swing shaft 1317 to rotate, and the rotation of the suction hood swing shaft 1317 can push the suction hood 1313 to swing back and forth. When the railway track bed vacuum car equipped with the separate sweeping and suction device provided in this embodiment of the application is running back and forth, the suction hood drive component 1316 drives the suction hood swing shaft 1317 to drive the suction hood 1313 to swing back and forth, so that its opening always faces the roller brush 1312 which is forward relative to the running direction. No matter which direction the railway track bed vacuum car is operating, maximum vacuuming efficiency can be guaranteed.
[0034] Furthermore, there are two sets of oscillating devices for the suction hood, symmetrically installed on both sides of the suction hood 1313. This symmetrical arrangement helps to ensure the balance and stability of the suction hood's oscillation.
[0035] This application also provides a specific implementation method for the swinging straw 133. Figure 6 This is a schematic diagram of the structure of the swinging straw provided in the embodiments of this application, as shown below. Figure 6As shown, the oscillating suction pipe 133 includes an oscillating flexible hose 1335 and an oscillating rigid tube 1334. One end of the oscillating flexible hose 1335 is connected to the suction component in the sweeping and suction assembly 131, and the other end of the oscillating flexible hose 1335 is connected to the front end of the oscillating rigid tube 1334. The rear end of the oscillating rigid tube 1334 is connected to subsequent equipment through a ball joint 1331. The oscillating rigid tube 1334 is equipped with an oscillating suction pipe drive device 1332 that pushes the oscillating rigid tube 1334 to oscillate to both sides. The oscillating suction pipe drive device 1332 provides the power for the overall oscillation of the oscillating suction pipe 133, ensuring that the inlet section of the oscillating suction pipe 133 is always directly above the interface connecting it to the suction hood 1313, keeping the hose vertical and ensuring suction efficiency. The use of a flexible hose in the lower section of the oscillating suction pipe 133 can compensate for positional errors with the suction hood opening. In some specific embodiments, the swing suction pipe drive device 1332 is a swing pipe cylinder. The cylinder body of the swing pipe cylinder is fixed on a fixed device (the fixed device can be a frame or the outer wall of a subsequent processing device, etc., a structure that does not move relative to the frame). The piston of the swing pipe cylinder is rotatably connected to the outer wall of the swing rigid pipe 1334. The extension and retraction of the piston of the swing pipe cylinder drives the swing rigid pipe 1334 to swing around the ball joint 1331, which connects to the subsequent equipment.
[0036] Furthermore, the oscillating rigid tube 1334 is also equipped with a pipeline explosion-proof valve 1333. The pipeline explosion-proof valve 1333 allows for the opening and closing of the oscillating suction tube, while also providing dust explosion protection. The pipeline explosion-proof valve 1333 can serve as the aforementioned downstream equipment.
[0037] like Figure 7 As shown in the figure, this application embodiment also provides a railway track bed vacuum truck, which includes a working vehicle 1 and a power vehicle 2 connected together by a connector. The working vehicle 1 includes a working frame 11, a detachable sweeping and suction device 13 as described above, a separation and filtration device 14, and a fan assembly 15. The sweeping and suction device 13 is installed at the bottom of the working frame 11, and the separation and filtration device 14 and the fan assembly 15 are installed on the working frame 11. The sweeping and suction device 13 is connected to the separation and filtration device 14 through a pipe, and the separation and filtration device 14 is connected to the fan assembly 15 through a pipe. The power vehicle 2 includes a power vehicle frame 21 and a power transmission device 23. The power transmission device 23 is installed on the power vehicle frame 21 and provides power to the entire vehicle.
[0038] During operation, the work vehicle 1 follows the power vehicle 2. The separate sweeping and suction device 13 sweeps up the ballast on the track and sucks it into the separation and filtration device 14. In the separation and filtration device 14, the ballast that enters with the airflow is settled and filtered, and finally, clean air is directly discharged. The collected ballast is recycled after the cleaning work is completed. The fan assembly 15 provides negative pressure for the separate sweeping and suction device 13 and the separation and filtration device 14. The separate sweeping and suction device 13 can move on its working plane, extending outward or retracting inward. Regardless of the track type, it can be delivered to the area that needs cleaning, making it highly versatile. The entire set of equipment can complete the cleaning work fully or semi-automatically, replacing the current manual cleaning method, reducing the number of workers, reducing labor intensity, improving work efficiency, and enhancing work safety.
