Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning vehicle for cleaning subway seats and floors. Background Technology

[0002] In the urban rail transit sector, subways, as an important mode of public transportation, carry a large number of passengers daily. With the continuous increase in subway operating mileage and passenger flow, the cleaning and maintenance of subway interiors has become increasingly important. Subway car seats and floors, due to frequent passenger use, easily accumulate dust, stains, and other debris. If not cleaned promptly, this not only affects the passenger experience but may also breed bacteria, posing a potential threat to passenger health. Therefore, efficient and comprehensive subway cleaning is crucial for ensuring the normal operation of the subway and the health of passengers.

[0003] In traditional subway cleaning operations, the cleaning of seats and floors mainly relies on manual labor. On the one hand, cleaning staff typically use simple tools such as brooms and mops to sweep and wipe the floors, and use cloths to manually clean the seats. On the other hand, some simple vacuum cleaners are also used to remove dust from the floor. While these traditional cleaning methods can accomplish the cleaning task to a certain extent, they require a significant investment of manpower and time. Furthermore, some large cleaning equipment, due to its size and lack of flexibility, is difficult to adapt to the narrow space and complex layout of subway cars, and cannot effectively clean confined areas such as around the seats.

[0004] Traditional subway cleaning methods have significant drawbacks. Manual cleaning is inefficient and cannot meet the demands of large-scale, high-frequency subway cleaning. Furthermore, the cleaning quality is easily affected by the working conditions and skill levels of the cleaning staff, resulting in inconsistent cleaning outcomes. On the other hand, existing large-scale cleaning equipment lacks flexibility and cannot reach key areas such as around seats for thorough cleaning, leaving blind spots in the subway car and failing to achieve the desired cleaning results.

[0005] Therefore, there is an urgent need to design a sweeping vehicle that can be used to clean both the ground and subway seats, specifically for cleaning subway seats. Summary of the Invention

[0006] In order to achieve comprehensive cleaning of subway seats and floors and solve the problem of incomplete cleaning by traditional cleaning methods, this application provides a cleaning vehicle for cleaning subway seats and floors.

[0007] The sweeping vehicle for cleaning subway seats and floors provided in this application adopts the following technical solution: A sweeping vehicle for cleaning seats and floors in a subway includes a frame, a mounting frame installed inside the frame, a sweeping mechanism installed on the bottom side of the frame, a sliding mechanism for driving the sweeping mechanism to extend out of the frame, a steering mechanism arranged on the mounting frame and connected to the sliding mechanism, a cleaning mechanism installed on the steering mechanism, and a roller mechanism arranged on the back side of the frame. The sweeping mechanism includes a rotating disc, a mop mounted on the rotating disc, and a drive motor that drives the rotating disc to rotate. The sliding mechanism includes a sliding track, a sliding block installed in the sliding track, a telescopic motor that drives the sliding block to reciprocate within the sliding track, and a sliding plate installed on the sliding block; The steering mechanism includes a rack 1 disposed on the side of the sliding block, a gear shaft 1 mounted on one side of the rack and meshing with the rack 1, a gear shaft 2 mounted on one side of the gear shaft and meshing with the gear shaft 1, a gear plate disposed on the lower side of the gear shaft 2 and meshing with the gear shaft 2, a sliding groove provided for sliding the gear plate and engaging with the gear block, a rack 2 mounted on the side of the gear plate, and a gear column mounted on the side of the rack 2 and meshing with the rack 2; The cleaning mechanism includes a rotating disc, a telescopic motor II installed in the rotating disc, a long rod arranged on the telescopic motor II, a seat cleaning wheel installed in the long rod, a scraper hinged to the top of the long rod, and an electric telescopic rod hinged to the long rod and the scraper.

[0008] By adopting the above technical solution, the frame provides the installation base for the various components of the sweeper. The sweeping mechanism drives the mop to rotate and sweep the ground through the rotating disc. The sliding mechanism allows the sweeping mechanism to slide out of the frame to expand the sweeping range. The steering mechanism can change the direction of the cleaning mechanism. The cleaning mechanism can clean and scrape the subway seats. The roller mechanism can assist the sweeper in moving and cleaning the ground, thus achieving effective cleaning of subway seats and the ground.

[0009] Optionally, the drive motor is mounted on the bottom side of the sliding plate, and the drive motor is provided with a rotating shaft. The rotating shaft is connected to the rotating disk, and the rotating shaft is installed off-center from the center of the rotating disk. The drive motor drives the rotating shaft to rotate and causes the rotating disk to rotate eccentrically.

[0010] By adopting the above technical solution, the sweeper can achieve eccentric rotation of the sweeping mechanism's rotating disc. Compared with the ordinary rotation method, eccentric rotation can make the mop's cleaning range wider and the cleaning effect better, and can more effectively clean subway seats and floors.

[0011] Optionally, the first gear shaft is perpendicular to the frame, and a gear is provided on one end of the first gear shaft near the frame and a bevel tooth is provided on the other end. The second gear shaft is perpendicular to the axis of the first gear shaft and includes a gear and a bevel tooth, and the bevel tooth and the bevel tooth mesh.

[0012] By adopting the above technical solution, the power transmission between gear shaft one and gear shaft two is realized in the vertical direction, providing a suitable transmission mode for the operation of the steering mechanism, thereby enabling the cleaning mechanism to realize the corresponding steering action and meet the cleaning needs of different angles when cleaning subway seats and the ground.

[0013] Optionally, the toothed plate meshes with the gear, a protruding limiting block is provided on the bottom side of the toothed plate, a groove is provided on the groove, the limiting block and the groove fit together, and the slide is fixedly installed on the mounting bracket.

[0014] By adopting the above technical solution, the sweeper has a frame, a mounting frame, a sweeping mechanism, a sliding mechanism, a steering mechanism, a cleaning mechanism, and a roller mechanism. The sweeping mechanism can sweep the ground, the sliding mechanism can allow the sweeping mechanism to slide out of the frame, the steering mechanism can enable the components to turn, the cleaning mechanism can clean the seat, and the roller mechanism can assist in sweeping. Among them, the toothed plate and the gear mesh, and the limiting block on the bottom side of the toothed plate fits with the groove on the slot. The sliding groove is fixed on the mounting frame, which can ensure that the toothed plate moves stably during the turning process, thereby making the steering mechanism run more stably and improving the working reliability of the sweeper's steering components.

[0015] Optionally, the gear column and the rotating disk are coaxially fixedly connected. The gear column is vertically mounted on the mounting bracket. A third gear is provided on the gear column. The third gear meshes with the second rack. The second rack moves to drive the third gear to rotate and drive the rotating disk to rotate.

[0016] By adopting the above technical solution, the frame, mounting frame, sweeping mechanism, sliding mechanism, steering mechanism, cleaning mechanism, and roller mechanism constitute a sweeping vehicle for cleaning subway seats and floors. The rotating disc and mop of the sweeping mechanism can sweep the floor, the sliding mechanism allows the sweeping mechanism to slide out of the frame to expand the cleaning range, the steering mechanism can adjust the direction, the cleaning mechanism can clean the seats, and the roller mechanism assists the sweeping vehicle in moving. The gear column and the rotating disc are coaxially fixedly connected and vertically mounted on the mounting frame. Gear three meshes with rack two. The movement of rack two drives gear three to rotate, which in turn drives the rotating disc to rotate, thereby realizing the rotation of the cleaning mechanism. The position and angle of the cleaning mechanism can be adjusted to better clean the seats.

[0017] Optionally, the long rod has a square opening inside, in which the seat cleaning wheel is installed. A hinge seat one and a hinge seat two are installed on the middle end of the long rod away from the telescopic motor two. The scraper is hinged to the hinge seat two. A hinge seat three is installed on the top of the scraper. The electric telescopic rod is installed on the hinge seat one and the hinge seat three.

[0018] By adopting the above technical solution, a square opening is set inside the long pole and seat cleaning wheels are installed to clean the subway seats. Hinged seat one, hinged seat two, and hinged seat three are set on the long pole, and a scraper is connected to it through an electric telescopic rod, which allows the scraper to flexibly adjust its angle and work better with the seat cleaning wheels to complete the cleaning of the seats.

[0019] Optionally, the roller mechanism includes a cleaning roller, support frames mounted on both sides of the cleaning roller, a reduction motor mounted on the frame, a synchronous pulley mounted on the reduction motor, a synchronous belt meshing on the synchronous pulley, and a driven pulley meshing on the synchronous pulley and the synchronous belt.

[0020] By adopting the above technical solution, the sweeper is equipped with a roller mechanism including a cleaning roller, a support frame, a geared motor, a synchronous pulley, a synchronous belt, and a driven pulley. The geared motor can drive the synchronous pulley, and the synchronous belt can make the driven pulley rotate, thereby driving the cleaning roller to rotate and achieving the cleaning of the subway floor.

[0021] Optionally, the cleaning roller is provided with rollers on both sides, the rollers are provided with bearings and are installed with the support frame, and the driven wheel is provided on the same side as the reduction motor.

[0022] By adopting the above technical solution, the roller is equipped with bearings and support frames, which makes the cleaning roller rotate more smoothly and stably, reducing friction and wear. The driven wheel and the geared motor are set on the same side, which facilitates the transmission and synchronization of power, ensuring that the cleaning roller can work normally under the drive of the geared motor, and improving the cleaning effect of the subway sweeper on the ground.

[0023] Optionally, the vehicle frame also includes a dust collection mechanism, which includes a dust collection hood, a roller brush installed inside the dust collection hood, and a dust collection box arranged inside the vehicle frame. The roller brush is connected to a brushless motor.

[0024] By adopting the above technical solution, the dust collection mechanism can effectively adsorb dust on subway seats and the ground. The roller brush rotates under the drive of a brushless motor, which can sweep the dust into the dust collection hood. The dust collection box can collect the sucked-in dust, thus cleaning the dust on subway seats and the ground.

[0025] Optionally, a handle is also provided on the back side of the frame for pushing and controlling the direction of the sweeper.

[0026] By adopting the above technical solution, a handle is installed on the back side of the frame to facilitate pushing the sweeper and controlling its direction.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotating disc of the sweeping mechanism drives the mop to rotate eccentrically, which can clean the narrow area around the subway seats, solving the problem of poor flexibility and inability to reach narrow areas by traditional large sweeping equipment; 2. The cleaning system can clean subway seats. With the help of scrapers and electric telescopic rods, it can effectively remove stains from the seats, improve the cleaning effect, and enhance the passenger riding experience. 3. The vacuuming mechanism can pick up dust from the ground, and together with the sweeping and washing mechanisms, it can achieve comprehensive cleaning of subway seats and floors, solving the problem of incomplete cleaning by traditional cleaning methods.

The cleaning vehicle can adapt to the narrow space of subway cars, achieving efficient and comprehensive cleaning of seats and floors. Through the cooperation of various mechanisms, the sweeping mechanism 3 is responsible for floor cleaning, the sliding mechanism 4 expands the cleaning range of the sweeping mechanism 3, the steering mechanism 5 adjusts the position of the cleaning mechanism 6, the cleaning mechanism 6 deeply cleans the seats, and the roller mechanism 7 assists in cleaning the floor, thereby achieving comprehensive cleaning.

[0039] Reference Figure 2As shown, a mounting bracket 2 is installed inside the frame 1. The mounting bracket 2 includes a flat mounting plate 21 and a mounting fixing plate 22 fixed to the mounting plate 21. A sliding mechanism 4 is provided on the bottom side of the mounting plate 21, and a steering mechanism 5 is installed on the mounting plate 21. The power generated by the sliding mechanism 4 acts on the steering mechanism 5, which controls the steering of the cleaning mechanism 6, allowing the seat cleaning wheels 64 and scraper 65 on the cleaning mechanism 6 to come into contact with the seat and clean it.

[0040] Reference Figure 2 and Figure 3 As shown, the sliding mechanism 4 includes a sliding track 41, a sliding block 42 installed in the sliding track 41, a telescopic motor 43 that drives the sliding block 42 to reciprocate in the sliding track 41, and a sliding plate 44 installed on the sliding block 42.

[0041] The sliding rail 41 is installed on the bottom side of the installation platform. A T-shaped groove is provided in the sliding rail 41. A T-shaped sliding block 42 is provided in the groove of the sliding rail 41 to fit the sliding rail 41. A sliding plate 44 is fixedly installed on the sliding block 42. A telescopic motor 43 is installed on the sliding block 42. After the telescopic motor 43 is started, the sliding block 42 reciprocates within the sliding rail 41, thereby realizing the movement of the sliding block 42. The sliding block 42 and the sliding plate 44 are fixedly connected. When the sliding block 42 slides, it will also drive the sliding plate 44 to move together.

[0042] Reference Figure 2 As shown, the sweeping mechanism 3 is located below the sliding plate 44. The sweeping mechanism 3 includes a rotating disk 31, a mop 32 mounted on the rotating disk 31, and a drive motor 33 that drives the rotating disk 31 to rotate. The drive motor 33 is mounted on the bottom side of the sliding plate 44, and the rotating shaft 34 on the drive motor 33 is connected to the rotating disk 31. The rotating shaft 34 is offset from the center of the rotating disk 31, so that the rotating disk 31 moves eccentrically when it rotates, increasing the cleaning area. The reciprocating movement of the sliding plate 44 allows the rotating disk 31 to extend or retract at the bottom of the frame 1. The extended rotating disk 31 can clean the floor under the seat.

[0043] Reference Figure 4 and Figure 5As shown, the steering mechanism 5 includes a rack 51 disposed on the side of the sliding block 42, a gear shaft 52 mounted on the side of the rack 51 and meshing with the rack 51, a gear shaft 53 mounted on the side of the gear shaft 52 and meshing with the gear shaft 52, a gear plate 54 disposed on the lower side of the gear shaft 53 and meshing with the gear shaft 53, a sliding groove provided for sliding the gear plate 54 and engaging with the gear block, a rack 541 mounted on the side of the gear plate 54, and a gear post 56 mounted on the side of the rack 541 and meshing with the rack 541.

[0044] Reference Figure 4 and Figure 5 As shown, the gear shaft 52 is vertically mounted on the base 11 of the frame 1. The base 11 is equipped with a bearing seat for the gear shaft 52 to be rotatably mounted. The gear shaft 52 includes a gear 521 and a bevel gear 522. The gear 521 is meshed with the rack 51 on the side of the sliding plate 44. Meanwhile, a sliding limit block 55 is provided on the mounting plate 21 of the mounting bracket 2. A toothed plate 54 is provided inside the sliding limit block 55. The wedge-shaped block on the toothed plate 54 is installed in the wedge groove inside the sliding limit block 55 to achieve the adaptation between the two. A gear shaft 53 is provided on the toothed plate 54 and is parallel to the base 11. The gear shaft 53 includes a gear 531 and a bevel gear 532. The gear 531 meshes with the toothed plate 54, and the bevel gear 532 meshes with the bevel gear 522. In order to achieve the fixed adaptation and meshing of the gear shaft 53 with the toothed plate 54 and the gear shaft 52, a fixing seat 57 is provided on the mounting plate 21. The gear shaft 53 is rotatably set on the fixing seat 57. A rack 2 541 is provided on one side of the gear plate 54. The rack 2 541 meshes with the gear 3 561 on the gear column 56. The gear column 56 is vertically mounted on the mounting plate 21. At the same time, the base 11 of the gear column 56 is provided with a rotating bearing that can rotate on the mounting plate 21.

[0045] The sliding plate 44 extends out of the base 11 of the frame 1 via the drive of the telescopic motor 43. The rack 51 on the sliding plate 44 drives the gear 521 on the gear shaft 52 to rotate, thus rotating the entire gear shaft 52. The bevel gear 522 on the gear shaft 52 drives the bevel gear 532 on the gear shaft 53 to rotate. The rotation of the gear shaft 53 causes the gear plate 54 to move outward toward the base 11. The rack 541 on the gear plate 54 moves with the gear plate 54, thereby driving the gear column 56 that meshes with it to rotate. The rotation of the gear column 56 rotates the entire cleaning mechanism 6 and extends it to the side of the cleaning vehicle, thus enabling the cleaning of the seats.

[0046] Reference Figure 4 and Figure 6As shown, the cleaning mechanism 6 is mounted on the gear column 56 and includes a rotating disk 61, a telescopic motor 62 mounted inside the rotating disk 61, a long rod 63 arranged on the telescopic motor 62, seat cleaning wheels 64 mounted inside the long rod 63, a scraper 65 hinged to the top of the long rod 63, and an electric telescopic rod 66 hinged to the long rod 63 and the scraper 65. The gear column 56 and the rotating disk 61 are coaxially fixed, and the rotation of the gear column 56 will drive the rotation of the entire rotating disk 61.

[0047] The rotating disc 61 has a notch on its periphery. A telescopic motor 62, installed inside the rotating disc 61, is connected to a long rod 63, which passes through the notch on the rotating disc 61. A square opening is provided on the long rod 63, within which a seat cleaning wheel 64 is installed. Bearings at both ends of the seat cleaning wheel 64 allow it to rotate within the opening of the long rod 63. The seat cleaning wheel 64 extends beyond the underside of the long rod 63 to allow it to better conform to the seat. A hinge seat 631 and a hinge seat 632 are provided at the middle and the end furthest from the telescopic motor of the long rod 63, respectively. A scraper 65 is hinged to the hinge seat 632, and a sponge block 67 is mounted on the scraper 65. A third hinge seat 651 is provided at the other end of the scraper 65. An electric telescopic rod 66 is hinged to both the third hinge seat 651 and the first hinge seat 631.

[0048] Telescopic motor 62 is connected to long rod 63. Telescopic motor 62 controls the extension and retraction of long rod 63, enabling cleaning of seats of different widths. A lint roller can be installed on seat cleaning wheel 64. The lint roller contacts the seat surface, adhering to the dust and completing the cleaning process. When the lint roller is full of dust, the lint side can be peeled off to expose a fresh surface for further cleaning. The sliding electric telescopic rod 66 allows the scraper 65 to tilt and rotate on long rod 63, better conforming to the seat back. The flexible sponge 67 conforms to the creases on the seat back, deforming to clean the creases without affecting the scraper's cleaning. When the sponge 67 becomes dirty, it can be removed from the scraper 65 and replaced with a new one for continued cleaning of the seat back.

[0049] Reference Figure 4 and Figure 7 As shown, the roller mechanism 7 includes a cleaning roller 71, a support frame 73 mounted on both sides of the cleaning roller 71, a reduction motor 74 mounted on the frame 1, a synchronous pulley 75 mounted on the reduction motor 74, a synchronous belt 76 meshing with the synchronous pulley 75, and a driven pulley 77 meshing with the synchronous belt 76.

[0050] Reference Figure 7As shown, roller mounting posts 72 are provided on both sides of the back of the frame 1. Support frames 73 are provided on the roller mounting posts 72, and cleaning rollers 71 are mounted on the support frames 73. Rollers 711 are also installed at both ends of the cleaning rollers 71. Bearings are provided on the rollers 711, and the rollers 711 are adapted to the support frames 73. The cleaning rollers 71 rotate on the support frames 73 to sweep the dust on the ground. A driven wheel 77 is provided on one side of the roller 711. A timing belt 76 is provided on the driven wheel 77, and a timing pulley 75 is also engaged on the timing belt 76. The timing pulley 75 is driven to rotate by a reduction motor 74, which in turn drives the driven wheel 77 to rotate. The rotation of the driven wheel 77 drives the cleaning roller 71 to rotate. The reduction motor 74 and the driven wheel 77 are located on the same side.

[0051] Reference Figure 2 and Figure 3 As shown, the dust collection mechanism 8 is installed at the front end of the sweeper. The dust collection mechanism 8 includes a dust collection hood 81, a roller brush 82 installed inside the dust collection hood 81, and a dust collection box 83 arranged within the frame 1. The dust collection hood 81 is located on the lower side of the base 11 and has a dust collection port (not shown in the figure) on the base 11. The roller brush 82 is installed on the dust collection port, and the roller brush 82 has threads. When the roller brush 82 rotates, the dust collection box 83 simultaneously collects dust from the dust collection port, covering the entire dust collection port. The roller brush 82 is connected to a brushless motor, which drives the roller brush 82 to rotate at high speed. The connection between the brushless motor and the roller brush 82 is existing technology and will not be described in detail. The brushless motor drives the roller brush 82 to rotate at high speed, and the high-speed rotating roller brush 82 sucks dust and other debris from the ground into the dust collection box 83 for collection.

[0052] The implementation principle of a sweeping vehicle for cleaning subway seats and floors according to an embodiment of this application is as follows: a vacuuming mechanism 8, a sweeping mechanism 3, and a roller mechanism 7 clean the floor. When the base 11 needs to be cleaned, the sliding mechanism 4 is activated, and the telescopic motor drives the sliding block 42 to slide within the sliding track 41, thereby causing the sliding plate 44 to slide out of the outside of the base 11, which in turn extends the sweeping mechanism 3, increasing the cleaning drive of the sweeping mechanism 3, and enabling the floor under the seats to be cleaned.

[0053] When the sliding plate 44 moves, the rack 51 on the sliding plate 44 drives the gear 521 on the gear shaft 52 to rotate. The rotation of the entire gear shaft 52 drives the gear shaft 53 to rotate. The gear 531 on the gear shaft 53 drives the toothed plate 54 to move on the fixed seat 57. When the toothed plate 54 moves, the rack 541 on its side drives the gear 561 on the gear column 56 to rotate, thereby rotating the rotating disk 61 on the gear column 56. This causes the entire cleaning mechanism 6 to rotate and extend the sweeper to clean the seat. The seat cleaning wheel 64 on the cleaning mechanism 6 adheres to and absorbs dust on the seat. The tilt of the scraper 65 is adjusted by the electric telescopic rod 66, so that the sponge block 67 on the scraper 65 can better fit with the seat back to clean the seat back. The cleaning rollers 71, located at the rear of the sweeper, are activated by a reduction motor 74 to rotate and clean the ground. A cleaning cloth can be mounted on the cleaning rollers 71. Simultaneously, when the sweeping mechanisms 3 extend to the sides of the sweeper, they cannot reach the middle section of the sweeper. At this point, the cleaning rollers 71 can clean the uncleaned areas in the middle of the sweeper. A handle 13 is located at the rear of the sweeper for easy pushing, and wheels 12 are provided for movement.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
