Description

Technical Field

[0001] This invention relates to the field of track cleaning technology, specifically to a track cleaning vehicle. Background Technology

[0002] Track is a line made of strip steel that allows trains, trams, and other vehicles to run. It allows trains to travel without turning. It generally consists of two parallel steel rails, which are fixed on sleepers. Underneath the sleepers is ballast or a monolithic track bed structure. The rails are fastened to the sleepers by a fastening system.

[0003] In the operating environment of urban rail transit, the tracks inside tunnels may experience accelerated rust and corrosion due to groundwater and moisture over long-term operation. Furthermore, prolonged wheel-rail contact can easily cause rail corrugation, requiring periodic rail grinding to smooth the rails. However, the metal debris generated during rail grinding can easily exacerbate the hazards of stray currents when it falls onto the fastener surface.

[0004] To avoid such hazards, current technologies typically rely on manual cleaning, which is inefficient and prone to generating secondary dust. Furthermore, existing mechanical cleaning equipment cannot effectively remove oil stains from fasteners and welds. Additionally, equipment cleaning of the tracks requires a train permit, making the process cumbersome and demanding in terms of coordination. Summary of the Invention

The lead screw is provided with a slider, and the slider is connected to a first connector and a second connector. The end of the first connector away from the slider is connected to the first cleaning motor, and the end of the second connector away from the slider is connected to the second cleaning motor.

[0011] In one embodiment, a first guide shaft and a second guide shaft are further provided between the first support base and the second support base, and the lead screw is disposed between the first guide shaft and the second guide shaft; both the first guide shaft and the second guide shaft pass through the slider.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Example 1 like Figure 1-4As shown, this embodiment includes a frame module 100, a sweeping module 400, and a dust collection module 200 detachably mounted on the frame module 100. In this embodiment, a cleaning module is also provided on the frame assembly 110, and the cleaning module is detachably mounted on the frame assembly 110. Thus, the dust collection module 200, the sweeping module 400, and the cleaning module can all be quickly assembled and disassembled through standardized interfaces, which facilitates maintenance and upgrades.

[0026] In this embodiment, the multi-module design is adopted to facilitate the direct transport of equipment from the subway platform to the track, enabling rapid installation and disassembly, while also facilitating normal construction operations during operational maintenance windows.

[0027] In this embodiment, the frame module 100 is also equipped with a weld inspection module, a track inspection module, a pipeline inspection module, etc.

[0028] After being exposed to wind and sun and used for a long time, the surface and sides of rails accumulate a large amount of dust, oil, and metal debris, especially in industrial areas or coastal regions. These impurities not only affect the contact performance between the rails and wheels but may also accelerate rail corrosion and reduce track stability. Traditional manual cleaning is inefficient and struggles to completely remove stubborn dirt, while existing mechanical cleaning equipment mainly focuses on cleaning the top surface of the rails and is insufficient for cleaning the sides.

[0029] Therefore, the cleaning module 400 includes two symmetrically arranged cleaning mechanisms 410; in this embodiment, the two cleaning mechanisms 410 have the same structure; and the two cleaning mechanisms 410 are arranged at the rear end of the frame module 100, respectively for synchronous cleaning operations on the two tracks.

[0030] The cleaning mechanism 410 includes a cleaning fixing plate 411 detachably mounted at the first end of the frame module 100. The cleaning fixing plate 411 is connected to a first cleaning motor 431 and a second cleaning motor 441. The output shaft of the first cleaning motor 431 is connected to a first cleaning brush 432, and the output shaft of the second cleaning motor 441 is connected to a second cleaning brush 442. A cleaning channel 440 for the track to pass through is provided between the first cleaning brush 432 and the second cleaning brush 442, ensuring that the first cleaning brush 432 and the second cleaning brush 442 can closely adhere to both sides of a single track during operation. Simultaneously, through the independent drive of the first cleaning motor 431 and the second cleaning motor 441, the first cleaning brush 432 and the second cleaning brush 442 can rotate synchronously or differentially, adapting to the linear speed differences under curved conditions and improving cleaning consistency.

[0031] The dust collection module 200 includes a dust collector 210 and a dust collection pipe connected to the dust collector 210. The dust collection port of the dust collection pipe points to the cleaning channel 440. In this embodiment, the dust collection port is located at the front end or rear end between the first cleaning brush 432 and the second cleaning brush 442 to efficiently suck up the dust and debris raised during the cleaning process.

[0032] The first cleaning brush 432 and the second cleaning brush 442 are equipped with cleaning dust collection hoods 430. The cleaning dust collection hoods 430 cover the top and outside of the first cleaning brush 432 and the second cleaning brush 442. At the same time, the cleaning dust collection hoods 430 have clearance openings for the track to pass through, and the edges of the clearance openings are provided with flexible sealing skirts to suppress dust overflow. A negative pressure chamber is formed inside the cleaning dust collection hoods 430, which, together with the dust collection port, generates directional airflow to effectively guide the dust into the dust collection pipe.

[0033] Current technologies typically rely on manual cleaning, which is inefficient and prone to generating secondary dust. Furthermore, existing cleaning equipment can only clean the inner areas of the tracks, failing to effectively clean the outer areas. The lack of dust collection on the outer tracks means that metal debris from grinding the rails can easily aggravate stray current hazards when it falls onto the fasteners.

[0034] Therefore, the dust collection port is set on the cleaning dust collection hood 430 and communicates with the cleaning dust collection hood 430, and is located at the front end or rear end between the first cleaning brush 432 and the second cleaning brush 442; thus, it can capture particulate matter raised during the cleaning process more efficiently and avoid secondary pollution.

[0035] Meanwhile, the cleaning dust collection hood 430 creates a closed negative pressure environment in the cleaning area, effectively curbing dust diffusion and improving dust collection efficiency; that is, increasing the suction of the dust collection port, thereby better sucking metal debris into the dust collection pipe and preventing it from remaining on the surface of the fastener and aggravating the damage of stray current.

[0036] In one embodiment, the cleaning dust collection hood 430 includes a first cleaning dust collection hood and a second cleaning dust collection hood, which are symmetrically arranged. The first cleaning dust collection hood is composed of a first top plate, a first left plate, a first front plate, and a first rear plate; the second cleaning dust collection hood is composed of a second top plate, a second right plate, a second front plate, and a second rear plate; and a clearance opening for the track to pass through is provided between the first cleaning dust collection hood and the second cleaning dust collection hood; a first cleaning motor 431 is mounted on the first top plate; and a second cleaning motor 441 is mounted on the second top plate.

[0037] In one embodiment, the cleaning dust collection hood 430 includes a first cleaning dust collection hood and a second cleaning dust collection hood, which are symmetrically arranged. The first cleaning dust collection hood is composed of a first top plate, a first bottom plate, a first left plate, a first front plate, and a first rear plate; the second cleaning dust collection hood is composed of a second top plate, a second bottom plate, a second right plate, a second front plate, and a second rear plate; and a clearance opening for the track to pass through is provided between the first cleaning dust collection hood and the second cleaning dust collection hood; a first cleaning motor 431 is mounted on the first top plate; and a second cleaning motor 441 is mounted on the second top plate.

[0038] In one embodiment, the cleaning dust collection hood 430 includes a top plate, a bottom plate, a left plate, a right plate, a front plate, and a rear plate, wherein the bottom plate, the front plate, and the rear plate have clearance openings in the middle for the track to pass through; a first cleaning brush 432 and a second cleaning brush 442 are located on both sides of the clearance openings for cleaning the track.

[0039] A lifting assembly 420 is provided on the cleaning mounting plate 411, and the first cleaning motor 431 and the second cleaning motor 441 are connected to the lifting assembly 420. In this embodiment, a control module is also included, which is electrically connected to the frame module 100, the lifting assembly 420, the first cleaning motor 431, and the second cleaning motor 441. Thus, the control module can automatically adjust the height of the lifting assembly 420 according to the track environment, thereby adjusting the contact pressure between the cleaning mechanism structure and the track to ensure cleaning effectiveness under complex working conditions. Simultaneously, the control module monitors the load status of the first cleaning motor 431 and the second cleaning motor 441 in real time and dynamically adjusts their speed output to achieve energy saving and high-efficiency synergy.

[0040] The lifting assembly 420 includes a first support base 421 and a second support base 422 connected to the cleaning fixing plate 411. A rotary motor 423 is mounted on the first support base 421, and a lead screw 424 is connected to the output shaft of the rotary motor 423. The lead screw 424 passes through the first support base 421 and is rotatably connected to the second support base 422. A slider 425 is mounted on the lead screw 424, and a first connector 426 and a second connector 427 are connected to the slider 425. The end of the first connector 426 away from the slider 425 is connected to the first cleaning motor 431, and the end of the second connector 427 away from the slider 425 is connected to the second cleaning motor 441. When the rotary motor 423 is started, it drives the lead screw 424 to rotate, causing the slider 425 to move along the lead screw axis. Thus, the height positions of the first cleaning motor 431 and the second cleaning motor 441 are synchronously adjusted through the first connector 426 and the second connector 427, thereby achieving automatic obstacle avoidance of the dust collection hood 430 when cleaning the track switch.

[0041] In this embodiment, the first connector 426 includes two parallel first connecting rods. One end of the two parallel first connecting rods is fixed to the slider 425, and the other end is fixed to the first sweeping motor 431. A reinforcing rib is provided between the two first connecting rods to improve structural stability. The structure of the second connector 427 is the same as that of the first connector 426.

[0042] A first guide shaft 428 and a second guide shaft 429 are also provided between the first support base 421 and the second support base 422, and a lead screw 424 is set between the first guide shaft 428 and the second guide shaft 429; both the first guide shaft 428 and the second guide shaft 429 pass through the slider 425; thus, the setting of the first guide shaft 428 and the second guide shaft 429 provides stable guidance for the lifting and lowering of the slider 425, effectively preventing it from deflecting or getting stuck during movement, ensuring the vertical lifting accuracy of the first sweeping motor 431 and the second sweeping motor 441; at the same time, it enhances the overall structural rigidity, reduces the impact of vibration on the sweeping operation, and improves the stability and responsiveness of the equipment in complex track environments.

[0043] The frame module 100 includes a frame assembly 110, a front axle assembly 120 and a rear axle assembly 130 located at the bottom of the frame assembly 110. Both the front axle assembly 120 and the rear axle assembly 130 are fixedly connected to the frame assembly 110 by bolts, ensuring a stable and reliable overall structure. The front axle assembly 120 and the rear axle assembly 130 are each equipped with a set of wheels. These wheels are connected to the axle body via a shock-absorbing mechanism, effectively buffering the impact from uneven tracks and improving the smoothness of equipment operation.

[0044] The frame assembly 110 is equipped with a fixed railing 115, and the dust collector 210 is connected to the fixed railing 115 by bolts; the cleaning fixing plate 411 is connected to the first end of the frame assembly 110 by bolts; thus, the dust collector 210 and the cleaning fixing plate 411 are stably installed on the frame assembly 110 by bolt connection, ensuring that the modules maintain precise relative positions during operation, improving the overall structure's seismic resistance and reliability; at the same time, it facilitates disassembly and maintenance, and improves work efficiency.

[0045] In this embodiment, the dust collection pipe is fixedly connected to the fixed railing 115 via a dust collection connecting rod. Thus, the dust collection connecting rod enhances the connection rigidity of the dust collection pipe, effectively preventing loosening or falling off due to vibration or bumps, and ensuring the continuous stability of the dust suction airflow channel. At the same time, the multi-point connection with the fixed railing 115 optimizes the distribution of the vehicle's center of gravity, improving the equipment's operational stability and structural reliability under complex working conditions.

[0046] The frame assembly 110 is equipped with a driver's seat 150 connected to the frame assembly 110; the control module includes a control display screen 310 mounted on the frame assembly 110, an image acquisition unit 320 electrically connected to the control display screen 310, and a battery assembly 330 connected to the control display screen 310; wherein, the image acquisition unit 320 is located at the second end of the frame assembly 110, that is, the image acquisition unit 320 is located at the front end of the frame assembly 110, and is used to identify track changes in real time; at the same time, the control display screen 310 is electrically connected to the lifting assembly 420, the dust collection module 200, the first sweeping motor 431, and the second sweeping motor 441.

[0047] In this embodiment, the control display screen 310 integrates a control circuit and is electrically connected to the lifting assembly 420, dust collection module 200, first sweeping motor 431, and second sweeping motor 441. The image acquisition unit 320 transmits real-time images of the forward track, and the system intelligently adjusts the sweeping height and suction power based on preset programs. The battery assembly 330 provides stable power to the entire system, ensuring continuous operation over extended periods. The driver's seat 150 is located in the middle of the frame assembly 110, facilitating real-time observation of the operating status and dynamic adjustments by the operator, thus improving operational safety and accuracy.

[0048] When the equipment travels to the turnout area, the image acquisition unit 320 identifies track changes in real time. The control module receives the signal and controls the rotating motor 423 to reverse, so that the slider 425 drives the first cleaning motor 431 and the second cleaning motor 441 to rise synchronously to ensure safe passage. After leaving, the motor rotates forward, the cleaning dust collection hood resets and continues to work.

[0049] The rack assembly 110 is also provided with a cleaning component, which includes a cleaning tank 500 for storing cleaning agent, a first cleaning component and a second cleaning component communicating with the cleaning tank 500; the first cleaning component and the second cleaning component are disposed at the bottom of the rack assembly 110; in this embodiment, the first cleaning component and the second cleaning component are respectively disposed on both sides of the bottom of the rack assembly 110 and are used to perform synchronous cleaning operations on the weld seams of the two tracks.

[0050] Both the first cleaning component and the second cleaning component include a first cleaning nozzle and a second cleaning nozzle (not shown in the figure). The first cleaning nozzle and the second cleaning nozzle are both connected to the cleaning box 500 through pipes. The first cleaning nozzle and the second cleaning nozzle are both facing the track surface or side. Thus, the first cleaning nozzle and the second cleaning nozzle symmetrically spray cleaning agent along both sides of the track to ensure full coverage of the weld area without dead corners. The cleaning agent is quantitatively delivered by the cleaning box 500 through pipes, and the spray volume is precisely controlled in conjunction with the vehicle's travel speed to avoid waste.

[0051] In this embodiment, the first cleaning component and the second cleaning component are located between the front axle assembly 120 and the rear axle assembly 130; both the first cleaning nozzle and the second cleaning nozzle are inclinedly disposed on the frame assembly 110; thus, the inclined angle design allows the cleaning agent to be sprayed onto the track surface or side weld at the optimal angle, enhancing the wetting and penetration effect and effectively removing the oxide layer and residual impurities; this angle range takes into account both the spray coverage width and impact force, avoids splash loss, ensures that the cleaning agent is evenly distributed in the weld area, and improves cleaning efficiency and quality consistency.

[0052] In this embodiment, the frame assembly 110 is also equipped with a vision sensor for identifying track welds. It is located in front of the cleaning module, collects track images in real time and transmits them to the control module; and accurately locates the position and shape deviation of the weld through image recognition algorithm, and dynamically adjusts the spraying timing of the cleaning component.

[0053] In one embodiment, the frame assembly 110 is provided with a plurality of sliding grooves; the sweeping module 400, the dust collection module 200, and the cleaning module are all provided with sliders that are slidably connected to the sliding grooves, so that the sweeping module 400, the dust collection module 200, and the cleaning module can be detachably connected through the setting of the sliding grooves and the sliders; in this embodiment, a threaded hole is provided on one side of the sliding groove and on the frame assembly 110. After the sweeping module 400, the dust collection module 200, and the cleaning module slide into the sliding groove, they are fixedly connected to the threaded hole by bolts, thereby restricting the movement of the sweeping module 400, the dust collection module 200, and the cleaning module.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
