Description

Technical Field

[0001] The utility model relates to the technical field of car washing machines, in particular to a mobile five-brush car washing machine. Background Art

[0002] In the existing gantry mobile bus washing machines, a common design is to clean the surface of the vehicle by combining multiple brushes. Although this type of equipment can cover most of the surface of the vehicle during the cleaning operation, due to the limited freedom of the brush system design, there are blind spots when cleaning the front and rear sides, bottom skirts, wheels and other locations of the bus, and the cleaning effect cannot reach the ideal state. These locations are often due to the complex shape of the vehicle, the narrow space, and the limited range of movement of the brush, which makes the brush unable to fully fit the cleaning, especially the body structure of large vehicles such as buses is relatively large and complex, which increases the difficulty of cleaning. This phenomenon not only affects the car washing effect, but may also cause local residual dirt, reducing the appearance and cleanliness of the vehicle.

[0003] At the same time, in the existing car washing machine technology, the design of the brush mechanism usually relies on the motor to drive the brush to rotate to achieve friction cleaning of the car body. However, when the brush is running at high speed, the cleaning liquid accumulated on the brush surface is easy to splash under the action of centrifugal force. This splashing water may fall on the cleaned car body again, causing secondary pollution. In addition, the water splashing into the surrounding environment not only pollutes the ground, but also may affect the surrounding vehicles or pedestrians. Especially when washing the car in an open environment, the phenomenon of accumulated water flying around will have an adverse effect on the surrounding environment, and the cleaning effect of the car washing cannot be effectively controlled.

[0004] In order to reduce this water splashing phenomenon, some car washing equipment is equipped with a water shield to block the water thrown out by the brush. However, the existing water shield design is easy to collide with the surface of the vehicle when the posture is adjusted with the brush due to its bulky structure and lack of a flexible adjustment system. Especially when washing vehicles with a large body height such as buses, it is difficult to adjust the height and angle of the brush and the water shield. A slight carelessness may cause a collision accident, affecting the safe use of the car washing equipment. In addition, once the water shield collides with the vehicle, it may cause damage to the brush of the car washing machine, affect the normal operation of the equipment, and even cause damage to the surface of the vehicle, increasing the risk and uncertainty in the cleaning process.

[0005] Traditional gantry mobile bus washing machines often rely on fixed mechanical designs and cannot flexibly adjust the brush's movement and cleaning force according to the actual size, shape and cleaning area of ​​the vehicle. This design results in the brush not being able to fully contact the vehicle body when it encounters irregular parts of the vehicle body, resulting in incomplete cleaning. At the same time, during the high-speed rotation of traditional brushes, the water shield cannot adjust its position synchronously with the brush, resulting in improper coordination between the brush and the water shield, further increasing the incidence of cleaning accidents.

[0050] It also includes a top brush mechanism 4, a main brush mechanism 5, and an auxiliary brush mechanism 6. The top brush mechanism 4 is mounted on the top of the gantry 1 and arranged in the horizontal direction. The top brush mechanism 4 is used to clean the top of the bus. The main brush mechanism 5 is mounted on the inner end of the retractable bracket 3 and arranged in the vertical direction. The main brush mechanism 5 is used to clean the front, rear and sides of the bus. The auxiliary brush mechanism 6 is mounted on the inner end of the movable bracket 2 and arranged in the vertical direction. The auxiliary brush mechanism 6 is set lower than the main brush mechanism 5 and is used to clean the wheel hub and skirt of the bus.

[0051] It also includes a walking component 7 and a retractable component 8. The walking component 7 is assembled on the mobile bracket 2 and controls the mobile bracket 2 to walk in the gantry 1. The retractable component 8 is connected to the retractable bracket 3 by power and controls the retractable bracket 3 to slide on the mobile bracket 2.

[0052] The bus to be cleaned is parked on the inner side of the gantry 1. When the gantry 1 moves along its own walking direction, it can drive the movable bracket 2, the retractable bracket 3, the top brush mechanism 4, the main brush mechanism 5, and the auxiliary brush mechanism 6 installed thereon to operate synchronously. Through the coordinated operation of various components, efficient cleaning of the bus can be achieved.

[0053] The inner side of the gantry 1 may also be equipped with components such as a spray pipe, a foam pipe and a fan. The spray pipe is used to spray clean water around the bus, the foam pipe is used to spray cleaning foam on the surface of the bus, and the fan is used to dry the water on the surface of the bus after cleaning.

[0054] The moving bracket 2 can be driven to move in the gantry 1 through the walking component 7, thereby driving the retractable bracket 3, the main brush mechanism 5, and the auxiliary brush mechanism 6 to move synchronously, so that the main brush mechanism 5 and the auxiliary brush mechanism 6 act on the side, wheel hub, and skirt of the bus, and in the process of the reciprocating movement of the gantry 1, the side, wheel hub, and skirt of the bus are cleaned, and the top brush mechanism 4 cleans the top of the bus.

[0055] When cleaning the front and rear of the bus, the main brush mechanism 5 is located at the front or rear side of the bus, and the retractable bracket 3 and the main brush mechanism 5 thereon are driven to move back and forth through the retractable assembly 8. During this process, the main brush mechanism 5 cleans the front and rear of the bus.

[0056] In the specific cleaning process, first, clean water is evenly sprayed onto the surface of the bus with the help of a spray pipe, and the preliminary cleaning of the bus is completed with the help of the top brush mechanism 4, the main brush mechanism 5, and the auxiliary brush mechanism 6. Then, the cleaning foam is evenly sprayed onto the bus with the help of a foam pipe, and the top brush mechanism 4, the main brush mechanism 5, and the auxiliary brush mechanism 6 continue to complete the secondary cleaning of the bus. Then, clean water is continued to be sprayed by the spray pipe to rinse off the foam cleaning agent remaining on the surface of the bus. Finally, the fan works to dry the residual water on the bus. After the cleaning of the bus is completed, the various components of the car washing machine are reset, and the bus can freely drive out of the cleaning station.

[0057] The main brush mechanism 5, the top brush mechanism 4 and the auxiliary brush mechanism 6 all have overlapping cleaning areas, so as to achieve cross-complementary cleaning of the bus, thereby cleaning all surfaces of the bus.

[0058] The gantry 1, the movable bracket 2, and the retractable bracket 3 are all made of flat-packed and welded steel, and the exposed part of the gantry 1 is covered with a stainless steel skin. The steel structure is surface-treated with hot-dip galvanizing and sprayed with high-grade polyester topcoat to ensure the waterproof and corrosion-resistant performance of the gantry 1, the movable bracket 2, and the retractable bracket 3.

[0059] Example 2

[0060] See also Figure 1-3 , 6, 7, in order to ensure that the gantry 1 can move stably in a straight line direction and to ensure that the movable bracket 2 is stably installed in the gantry 1, the following technical solution is provided.

[0061] Traveling guide rails 11 arranged in the horizontal direction are arranged on both sides of the bottom of the gantry 1, and supporting wheels 12 matched with the traveling guide rails 11 are rotatably installed at the bottom of the gantry 1.

[0062] A lateral assembly groove 13 is provided on the inner side wall of the gantry 1 , and the movable bracket 2 is arranged in the lateral assembly groove 13 .

[0063] The coordinated design of the walking guide rails 11 and the supporting wheels 12 can ensure that the gantry 1 can move stably in a straight line direction to ensure the stable cleaning of the bus. The lateral assembly grooves 13 arranged on the inner side of the gantry 1 can ensure that the movable bracket 2 does not occupy the inner space of the gantry 1 when it is retracted, thereby ensuring the normal passage of the bus.

[0064] In order to ensure that the mobile support 2 can move stably in the gantry 1 and ensure that the moving directions of the mobile support 2 and the gantry support remain vertical, the following technical solution is provided.

[0065] A top bracket 14 is fixedly connected to the inner top wall of the gantry 1, and both ends of the top bracket 14 are arranged in the lateral assembly grooves 13. An upper movable guide rail 15 and a lower movable guide rail 16 are mounted on the top bracket 14, and the upper movable guide rail 15 and the lower movable guide rail 16 are both kept perpendicular to the walking guide rail 11.

[0066] An upper moving wheel 21 and a lower moving wheel 22 which are respectively matched with the upper moving guide rail 15 and the lower moving guide rail 16 are rotatably mounted on the moving bracket 2 .

[0067] The setting of the top bracket 14 can ensure that the upper movable guide rail 15 and the lower movable guide rail 16 are stably installed therein, and then cooperate with the upper movable wheel 21 and the lower movable wheel 22 to realize the design requirement of stable movement of the movable bracket 2 in the gantry 1 in a straight direction.

[0068] Since the upper movable guide rail 15 and the lower movable guide rail 16 are arranged vertically with the travel guide rail 11 , the vertical operation requirement of the travel direction of the gantry 1 and the travel direction of the movable bracket 2 is achieved.

[0069] Example 3

[0070] See also Figure 6-9 In order to ensure that the walking assembly 7 can drive the moving bracket 2 to stably run along the direction of the upper moving guide rail 15 and the lower moving guide rail 16, the following technical solution is provided.

[0071] The walking assembly 7 includes a reduction motor 71 and multiple groups of upper mounting shafts 72 and lower mounting shafts 73. The upper mounting shafts 72 and lower mounting shafts 73 are all rotatably mounted on the moving bracket 2. The reduction motor 71 is fixedly mounted on the moving bracket 2 and is dynamically connected to one group of upper mounting shafts 72. The two ends of the upper mounting shafts 72 are fixedly connected to the upper moving wheels 21, and the two ends of the lower mounting shafts 73 are fixedly connected to the lower moving wheels 22.

[0072] When it is necessary to control the movement of the mobile bracket 2, the reduction motor 71 is controlled to operate, thereby driving the upper installation shaft 72 connected to its power and the upper moving wheel 21 thereon to operate, so as to drive the mobile bracket 2 to move stably along the upper moving guide rail 15 and the lower moving guide rail 16.

[0073] A braking system can also be installed on the walking assembly 7 to lock and fix the upper moving wheels 21 and the lower moving wheels 22 to limit the movement of the moving bracket 2, thereby ensuring that the retractable bracket 3, the main brush mechanism 5, and the auxiliary brush mechanism 6 assembled on the moving bracket 2 maintain a stable posture to achieve effective cleaning of the bus.

[0074] In order to ensure that the walking support can be stably installed on the moving support 2 and driven by the retracting assembly 8 to move in a direction parallel to the upper moving guide rail 15 and the lower moving guide rail 16, the following technical solution is provided.

[0075] A guide groove 23 is provided in the movable bracket 2 , and the guide groove 23 is arranged parallel to the upper movable guide rail 15 and the lower movable guide rail 16 .

[0076] The retractable assembly 8 includes an adjusting screw 81 and a driving motor A82. The adjusting screw 81 is rotatably mounted on the movable bracket 2 and is arranged parallel to the guide groove 23. The driving motor A82 is fixedly mounted on the movable bracket 2 and maintains a power connection with the adjusting screw 81. The retractable bracket 3 is rotationally connected to the adjusting screw 81.

[0077] The setting of the guide groove 23 can ensure that the retractable bracket 3 moves stably in a straight line direction. When the retractable component 8 is running, the driving motor A82 is controlled to drive the adjusting screw 81 to operate, thereby driving the retractable bracket 3 to slide stably along the guide groove 23, so as to realize the retractable bracket 3 in the mobile bracket 2. Adjustment along the straight line direction ensures stable adjustment of the retractable posture of the main brush mechanism 5.

[0078] Example 4

[0079] See also Figure 4 , 5 , 10-12, in order to ensure that the top brush mechanism 4 can be stably installed on the inner top of the gantry 1 and can be height-adjusted to achieve effective cleaning of the top of the bus, the following technical solution is provided.

[0080] The top brush mechanism 4 includes a water retaining cover A41, a horizontal brush 42, a main swing frame 43, an auxiliary swing frame 44, a hydraulic telescopic cylinder 45, and a driving motor B46. The horizontal brush 42 is rotatably installed in the water retaining cover A41, and the water retaining cover A41 semi-wrapped arrangement of the horizontal brush 42. The driving motor B46 is fixedly installed on the outside of the water retaining cover A41. A driving bevel gear A461 is fixedly connected to the output shaft of the driving motor B46. A transmission bevel gear that meshes with the driving bevel gear A461 is fixedly connected to the axis of the horizontal brush 42. The two ends of the main swing frame 43 and the auxiliary swing frame 44 are respectively hinged to the water retaining cover A41 and the gantry 1. The two ends of the hydraulic telescopic cylinder 45 are respectively hinged to the main swing frame 43 and the gantry 1.

[0081] During the telescopic movement of the hydraulic telescopic cylinder 45, the water shield A41 and the horizontal brush 42 assembled in the water shield A41 can be driven to rotate around the hinge point between the main swing frame 43 and the gantry 1 through the main swing frame 43, thereby realizing the height adjustment of the water shield A41 and the horizontal brush 42. By adding a secondary swing frame 44, it can be ensured that the water shield A41 always moves at a specific angle, thereby ensuring that the water shield A41 is always above the horizontal brush 42.

[0082] When the driving motor B46 drives the horizontal brush 42 to operate through the driving bevel gear A461 and the transmission bevel gear A421, it can effectively clean the bus, and the water thrown out by the horizontal brush 42 due to the centrifugal force can be stably blocked by the water retaining cover A41 to prevent water droplets from flying around and affecting the surrounding environment.

[0083] In order to ensure that the main brush mechanism 5 can be stably installed on the retractable bracket 3 and realize effective cleaning of the front, rear and sides of the bus, the following technical solution is provided.

[0084] The main brush mechanism 5 includes a water retaining cover B51, a large upright brush 52, a driving motor C53, and a posture adjustment component. The water retaining cover B51 is rotatably installed on the inner end of the retractable bracket 3 and is arranged in the vertical direction. The large upright brush 52 is rotatably installed in the water retaining cover B51. The water retaining cover B51 semi-wrapped the large upright brush 52. The driving motor C53 is fixedly installed on the retractable bracket 3. A driving bevel gear B531 is fixedly connected to the output shaft of the driving motor C53. A transmission bevel gear B521 that meshes with the driving bevel gear B531 is fixedly connected to the axis of the large upright brush 52. The posture adjustment component maintains linkage with the water retaining cover B51.

[0085] When the driving motor C53 is running, it can drive the large vertical brush 52 to operate by driving the bevel gear B531 and the transmission bevel gear B521, so that the bus can be effectively cleaned when it comes into contact with the bus. The water shield B51 is driven to rotate by the posture adjustment component to keep the water shield B51 on the side away from the bus at all times. When the large vertical brush 52 cleans the front, back or sides of the bus, the water shield B51 can be effectively prevented from colliding with the bus.

[0086] The water thrown out by the large vertical brush 52 due to the centrifugal force can be stably blocked by the water retaining cover B51, so as to prevent the water droplets from flying around and affecting the surrounding environment.

[0087] In order to ensure that the posture adjustment component can drive the water shield B51 to operate stably, and in this process ensure that the large vertical brush 52 can be driven by the driving motor C53 to operate stably, the following technical solution is provided.

[0088] The posture adjustment component includes an adjustment motor 541 and a matching combination of a worm wheel 542 and a worm 543. The worm wheel 542 is fixed to the axis of the water retaining cover B51, and the transmission bevel gear B521 is coaxially arranged with the worm wheel 542. The adjustment motor 541 is fixedly installed on the retractable bracket 3 and is connected to the worm 543 in terms of power.

[0089] The water shield B51 and the large vertical brush 52 are arranged coaxially. When the water shield B51 is adjusted through the posture adjustment component, it will not affect the normal operation of the large vertical brush 52, and when the large vertical brush 52 operates normally, it will not interfere with the posture adjustment of the water shield B51.

[0090] When the posture adjustment component is running, the combination of the worm 543 and the worm wheel 542 is driven by the adjustment motor 541 to drive the water shield B51 to rotate around its own axis. The combination of the worm 543 and the worm wheel 542 has the effect of reducing speed and increasing torque, and can amplify the torque of the adjustment motor 541 to drive the water shield B51 to rotate stably. At the same time, the combination of the worm 543 and the worm wheel 542 also has a self-locking effect, and the power can only be transmitted to the worm wheel 542 in one direction through the worm 543. After the posture adjustment of the water shield B51 is completed, the control adjustment motor 541 is turned off to cut off the power. At this time, the water shield B51 and the worm wheel 542 thereon are locked by the worm 543 and will not rotate due to external forces.

[0091] In order to ensure that the auxiliary brush mechanism 6 can be stably installed on the mobile bracket 2 and achieve the effect of cleaning the side wheel hub and skirt of the bus, the following technical solution is provided.

[0092] The auxiliary brush mechanism 6 includes a water shield C61, a small vertical brush 62, and a driving motor D63. The water shield C61 is fixedly installed on the movable bracket 2, and the small vertical brush 62 is rotatably installed in the water shield C61. The water shield C61 semi-wrapped arrangement of the small vertical brush 62, the driving motor D63 is fixedly installed on the outside of the water shield C61, and a driving bevel gear C631 is fixedly connected to the output shaft of the driving motor D63. A transmission bevel gear C621 that meshes with the driving bevel gear C631 is fixedly connected to the axis center of the small vertical brush 62.

[0093] When the driving motor D63 is running, the small vertical brush 62 can be driven to operate by driving the bevel gear C631 and the transmission bevel gear C621, so that the skirt and the wheel hub at the bottom of the bus can be effectively cleaned when they come into contact with them. The water shield C61 is arranged on the outside of the small vertical brush 62. The water thrown out by the small vertical brush 62 due to the centrifugal force can be stably blocked by the water shield B51 to prevent water droplets from flying around and affecting the surrounding environment.
