Description

Technical Field

[0001] The invention relates to the technical field of car washing equipment for washing various small vehicles, in particular to an overpass type contact-free car washing machine. Background Art

[0002] With the continuous improvement of urban taste, the number of cars owned in cities is constantly increasing. At the same time, the corresponding car washing businesses are distributed in various areas of the city. At present, the car washing industry widely uses two forms: brush washing machines and contactless car washing machines.

[0003] Among them, some car washers will inevitably leave scratches on the surface of the car because the brush is in close contact with the surface of the car. Although this cleaning method can remove dirt to a certain extent, the scratches that may appear on the surface of the car affect the user's experience.

[0004] To solve the drawbacks of brush-type car washers, contact-free car washers have emerged on the market. Contact-free car washers use high-pressure water and detergent to clean the vehicle, avoiding direct contact with the surface of the car, thereby reducing the risk of scratches.

[0005] However, most of the current contact-free car washers are walk-behind designs, which are large in size and easily limited by site space, and cannot be installed and used in small or irregular sites. In addition, the existing contact-free car washers can only drive the spray pipe to move back and forth in a straight line, which is difficult to adjust according to the height change of the vehicle, and cannot ensure that the water vapor evenly covers the surface of the vehicle, which affects the cleaning effect.

[0006] In addition, the spray pipe of the existing contact-free car washing machine is also difficult to adjust the angle, resulting in poor cleaning effects on the front and rear of the car, making it difficult to achieve effective cleaning of the vehicle in all directions. Therefore, an improved solution that can solve the above problems is urgently needed to improve the cleaning efficiency and cleaning effect of the contact-free car washing machine, while reducing the requirements for the installation site. Summary of the invention

DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0052] Example 1

[0053] See also Figure 1, 3 , 7, 11, 14, an overpass type contact-free car washing machine, comprising a traveling trolley 1, a lifting assembly 2, a reversing assembly 3, and a spraying assembly 4, the traveling trolley 1 moves in a straight direction, the lifting assembly 2 is assembled on the traveling trolley 1, the reversing assembly 3 is assembled on the movable part of the lifting assembly 2, and the spraying assembly 4 is matched with the reversing assembly 3.

[0054] The reversing assembly 3 includes a rotating seat 31 , an adjusting motor B32 , and a reversing mechanism 33 . Two sets of rotating seats 31 are rotatably mounted on the movable part of the lifting assembly 2 . The adjusting motor B32 maintains power connection with the two sets of rotating seats 31 through the reversing mechanism 33 .

[0055] The spray assembly 4 includes two groups that are symmetrically arranged. The two groups of spray assemblies 4 include a main bracket 41, a sub-bracket 42, a main spray pipe 43, a sub-spray pipe 44, and an inner sleeve 45. The main bracket 41 is fixedly connected to the rotating seat 31, the sub-bracket 42 is slidably installed at the bottom of the main bracket 41 and moves up and down in the vertical direction. The main spray pipe 43 and the sub-spray pipe 44 are respectively assembled to the main bracket 41 and the sub-bracket 42. The inner sleeve 45 is fixedly installed on the main bracket 41 and maintains a sealing fit with the inner wall of the sub-spray pipe 44. The sub-bracket 42 maintains a power connection with the lifting assembly 2 through a transmission assembly.

[0056] The car washing machine is mainly used for washing various types of small vehicles. The traveling trolley 1 is placed above the space and reciprocates in a straight line, driving the lifting component 2, the reversing component 3, and the spray component 4 to operate synchronously. When washing the vehicle, the small vehicle is parked under the path of the traveling trolley 1 and placed between two groups of symmetrically distributed spray components 4.

[0057] The lifting component 2 can drive the reversing component 3 and the main bracket 41 to move up and down synchronously. During this process, it can synchronously drive the sub-bracket 42 to move up and down in the vertical direction in the opposite direction. That is, when the main bracket 41 descends (or rises) to a specific height, the sub-bracket 42 synchronously rises (or descends) to a specific height, so that the sub-bracket 42 always maintains a set distance from the ground, avoiding the lifting movement of the main bracket 41 affecting the position and posture of the sub-bracket 42, thereby affecting the effective cleaning effect of the vehicle tires and side skirts.

[0058] By adjusting the height of the main bracket 41 through the lifting component 2, it can adapt to small vehicles of different heights, so that the water vapor sprayed from the main spray pipe 43 and the auxiliary spray pipe 44 on the main bracket 41 and the auxiliary bracket 42 can effectively act on the vehicle parked inside, thereby improving the cleaning efficiency and cleaning quality of the vehicle.

[0059] The main spray pipe 43 is arranged along the extension direction of the main bracket 41, and the main spray pipe 43 is evenly equipped with main nozzles 431 arranged toward the inside. The auxiliary spray pipe 44 is arranged along the extension direction of the auxiliary bracket 42, and the auxiliary spray pipe 44 is evenly equipped with auxiliary nozzles 441 arranged toward the inside.

[0060] The auxiliary spray pipe 44 extends upward to a certain height on the main bracket 41. During the lifting and lowering movement of the auxiliary bracket 42, it can ensure that the main spray pipe 43 and the auxiliary spray pipe 44 have an overlapping part in height, thereby ensuring that the water vapor sprayed by the main nozzle 431 and the auxiliary nozzle 441 can be evenly distributed on the inner side of the spray assembly 4.

[0061] When the auxiliary bracket 42 is in a raised position relative to the main bracket 41, the inner sleeve 45 can block the auxiliary nozzle 441 at the top of the auxiliary spray pipe 44 that overlaps with the main spray pipe 43, thereby preventing the water vapor sprayed from this part of the auxiliary nozzle from overlapping with the water vapor sprayed from the main nozzle 431 at the bottom of the main spray pipe 43, thereby avoiding waste of water resources while ensuring that the main spray pipe 43 and the auxiliary spray pipe 44 spray water vapor evenly.

[0062] The spray pipe can not only supply clean water, but also supply cleaning agent or a mixture of cleaning agent and clean water. The combined use of cleaning agent and clean water can ensure the cleanliness of vehicle cleaning.

[0063] For the reversing mechanism 33, the adjusting motor B32 can drive the two groups of rotating seats 31 to rotate in opposite directions at the same angle through the reversing mechanism 33, thereby driving the spray assembly 4 assembled on the two groups of rotating seats 31 to rotate synchronously. The spray assembly 4 during the flipping process can effectively clean the front and rear parts of the small vehicle.

[0064] Example 2

[0065] Please refer to 1 and 2. In order to ensure that the traveling trolley 1 can be stably assembled and stably move in a straight direction, and then the traveling trolley 1 drives the lifting component 2, the reversing component 3, and the spray component 4 to operate stably, so as to achieve contact-free cleaning of the small vehicle parked under the traveling trolley 1 and inside the spray component 4, the following technical solution is provided.

[0066] It also includes a steel frame channel 5, which is fixedly installed on the horizontal ground. Two groups of connecting frame plates 51 arranged along the length direction of the steel frame channel 5 are fixedly connected to the top of the steel frame channel 5. The upper and lower sides of the two groups of connecting frame plates 51 are respectively fixedly installed with upper guide rails 511 and lower guide rails 512. The traveling trolley 1 is assembled on the upper guide rails 511 and the lower guide rails 512 and travels along the traveling guide rails.

[0067] The steel frame channel 5 is composed of multiple groups of uniform arc-shaped brackets 52, each group of arc-shaped brackets 52 is fixedly connected by multiple sections of reinforcing rods 53 arranged horizontally, and a mounting pad 521 is welded at the bottom of each group of arc-shaped brackets 52, and the mounting pad 521 can be fixed on the horizontal foundation by a bolt assembly. In order to prevent the steel frame channel 5 from interfering with the spatial movement of the running traveling trolley 1 and the lifting assembly 2 assembled thereon, a clearance groove 54 is opened at the top of the steel frame channel 5, and the traveling trolley 1 and the lifting assembly 2 are placed in the clearance groove 54.

[0068] When installing the car washing machine indoors or near a wall in a narrow space, the steel frame channel 5 structure may not be used, and the connecting frame plate 51 may be fixedly installed on the indoor roof or wall, and the upper guide rail 511 and the lower guide rail 512 may be fixedly installed on the connecting frame plate 51. It is only necessary to ensure that the traveling trolley 1 moves along a straight line and has many advantages of flexible use of the site.

[0069] In order to facilitate the cleaning of the bottom of the vehicle, a ground spray pipe is installed under the ground on one side of the entrance of the steel frame channel 5. The ground spray pipe is provided with a vertical nozzle arranged vertically upward. The vertical nozzle can spray cleaning agent and clean water upward to flush the chassis part of the vehicle entering the steel frame channel 5.

[0072] Two sets of active shafts 11 and passive shafts 12 are rotatably mounted on the traveling trolley 1. Both ends of the active shaft 11 are fixedly connected to active running wheels 111 arranged on the outside of the traveling trolley 1. The active running wheels 111 are assembled on the top of the upper guide rail 511. Both ends of the passive shaft 12 are fixedly connected to passive running wheels 121 arranged on the outside of the traveling trolley 1. The passive running wheels 121 are assembled on the bottom of the lower guide rail 512.

[0073] A reduction motor 13 is also fixedly installed inside the traveling trolley 1 , and the reduction motor 13 is dynamically connected to one of the driving shafts 11 . A transmission sprocket 112 is fixedly connected to the two driving shafts 11 , and the two transmission sprockets 112 realize chain transmission through a transmission chain 113 .

[0074] The upper guide rail 511 , the lower guide rail 512 , the active running wheel 111 , and the passive running wheel 121 are matched in combination to ensure that the traveling vehicle 1 can stably travel along the straight line direction where the upper guide rail 511 and the lower guide rail 512 are located.

[0075] A strip through hole 14 arranged in the vertical direction is opened on the side wall of the traveling trolley 1, and an adjusting shaft 141 for height adjustment along the length direction of the strip through hole 14 is installed in the suitcase assembly through hole. The adjusting shaft 141 is fixed to a specific height of the strip through hole 14 by a locking nut 142, and a tensioning sprocket 143 is rotatably installed on the adjusting shaft 141. The tensioning sprocket 143 meshes with the transmission chain 113 and keeps the transmission chain 113 in a tensioned state.

[0076] When the reduction motor 13 is running, it can drive the driving shaft 11 directly connected to it to operate stably, and then drive the other driving shaft 11 to operate synchronously through the combination of the transmission sprocket 112 and the transmission chain 113, so as to drive each group of active walking wheels 111 to operate synchronously, and with the cooperation of the active walking wheels 111 and the passive walking wheels 121 as well as the upper guide rails 511 and the lower guide rails 512, the stable movement of the traveling trolley 1 is achieved.

[0078] A locking head 151 is fixedly connected to the active shaft 11 and the passive shaft 12, and a sliding plate 152 is slidably installed on the traveling trolley 1. Both ends of the sliding plate 152 are fixedly connected with locking grooves 153 that are nested and matched with the locking head 151, and the locking grooves 153 are arranged throughout the active shaft 11 or the passive shaft 12; a positioning cylinder 154 is fixedly installed on the traveling trolley 1, and the movable end of the positioning cylinder 154 is fixedly connected to the sliding plate 152.

[0080] When the traveling trolley 1 is operating normally, the positioning cylinder 154 is in a retracted state, and the locking groove 153 and the corresponding locking head 151 are in a separated posture. At this time, the active shaft 11 and the passive shaft 12 can drive the locking head 151 thereon to stably rotate at the axis position where the locking groove 153 is located. When the traveling trolley 1 is in a parking state and needs to be locked and positioned, the positioning cylinder 154 is controlled to extend to drive the sliding plate 152 and the locking groove 153 thereon to slide along the axis where the active shaft 11 and the passive shaft 12 are located, so that the locking groove 153 and the corresponding locking head 151 are nested and locked to limit the operation of the active shaft 11, the passive shaft 12 and the active running wheels 111 and the passive running wheels 121 thereon, thereby locking the traveling trolley 1 to the specific positions of the upper guide rail 511 and the lower guide rail 512.

The installation shaft 331 is rotatably installed at the bottom of the lifting bracket 22. Two sets of driving bevel gears B332 that are symmetrically arranged are fixedly connected at both ends of the installation shaft 331. Transmission bevel gears B333 are fixedly connected to the two sets of rotating seats 31. The transmission bevel gear B333 is meshed with the driving bevel gear B332 on the same side. The worm wheel 334 is fixedly connected to the installation shaft 331, and the worm 335 is fixedly connected to the output shaft of the adjustment motor B32.

[0089] The power of the adjusting motor B32 can be transmitted to the installation through the combination of the worm 335 and the worm wheel 334. Since the structure of the worm wheel 334 and the worm 335 has the effect of reducing speed and increasing torque, the torque of the adjusting motor B32 can be amplified to drive the installation shaft 331 to be stable and uniform. At the same time, it has a self-locking effect, that is, power can only be transmitted to the worm wheel 334 through the worm 335, and power cannot be transmitted to the worm 335 through the worm wheel 334. After the adjusting motor B32 drives the worm 335 and the worm wheel 334 to operate to adjust the deflection angle of the spray component 4 and turns off the adjusting motor B32, the two groups of spray components 4 are in a locked state and cannot passively adjust their deflection angles, ensuring that the spray component 4 is not disturbed by other forces during operation, thereby improving its stability.

[0090] Since the two sets of driving bevel gears B332 are arranged symmetrically, when the two sets of driving bevel gears B332 are driven to operate synchronously through the installation shaft 331, the two sets of transmission bevel gears B333 and the rotating seat 31 can be driven to operate in the opposite direction, thereby driving the two sets of spray assemblies 4 to always maintain constant speed reverse deflection, so as to effectively clean the front and rear of small vehicles and avoid collision between the deflected spray assemblies 4 and the vehicle being cleaned.

[0091] Example 5

[0092] See also Figure 7 , 8 , 12, in order to ensure that the main bracket 41, the auxiliary bracket 42 and the main spray pipe 43 and the auxiliary spray pipe 44 installed thereon can effectively wrap the vehicle being cleaned, and at the same time ensure that the auxiliary bracket 42 can be stably raised and lowered along the main bracket 41, the following technical solution is provided.

[0093] The main bracket 41 includes a transverse bracket 411, a vertical bracket 412 and an oblique bracket 413 fixedly connected between the transverse bracket 411 and the vertical bracket 412. The end of the transverse bracket 411 is fixedly connected to the bottom of the rotating seat 31, and the auxiliary bracket 42 is slidably installed at the bottom of the vertical bracket 412.

[0094] A secondary lead screw 414 arranged in the vertical direction is rotatably installed at the bottom of the vertical bracket 412, and the top of the secondary bracket 42 is rotationally connected to the secondary lead screw 414; a horizontal connecting shaft 415, a vertical connecting shaft 416, and an oblique connecting shaft 417 are rotatably installed in the horizontal bracket 411, the vertical bracket 412, and the oblique bracket 413 respectively, and the horizontal connecting shaft 415 is dynamically connected to the main lead screw 23 through a transmission assembly, the vertical connecting shaft 416 is coaxially fixedly connected to the secondary lead screw 414, and both ends of the oblique connecting shaft 417 are dynamically connected to the horizontal connecting shaft 415 and the vertical connecting shaft 416 through universal joints 418.

[0095] The main bracket 41 is designed as an L-shaped structure composed of a horizontal bracket 411, a vertical bracket 412, and an oblique bracket 413, and cooperates with the auxiliary bracket 42 below, so that the spray assembly 4 can be set up on both sides of the vehicle to be cleaned, and cooperate with the main spray pipe 43 and auxiliary spray pipe 44 installed thereon to effectively clean the surroundings of the vehicle.

[0096] When the adjusting motor A24 in the lifting assembly 2 drives the main screw 23 to operate, it can drive the transverse connecting shaft 415 installed in the transverse bracket 411 to operate synchronously. Through the setting of the universal joint 418, the power is transmitted to the auxiliary screw 414 along the transverse connecting shaft 415, the oblique connecting shaft 417, and the vertical connecting shaft 416. The operating auxiliary screw 414 drives the auxiliary bracket 42 to move up and down in the vertical direction.

[0097] By designing the spiral direction of the thread grooves on the main screw 23 and the auxiliary screw 414, it can be ensured that while the lifting bracket 22 drives the main bracket 41 to move downward, the auxiliary screw 414 drives the auxiliary bracket 42 to rise, so that the auxiliary screw 414 always remains relatively still and maintains a specific distance from the ground.

[0098] See also Fig. 9 , 10 , 12, 13, in order to realize the power connection between the main screw 23 and the transverse connecting shaft 415 and ensure that the power of the main screw 23 is stably distributed to the transverse connecting shafts 415 in the two groups of spray assemblies 4, the following technical solution is provided.

[0099] The transmission assembly includes a transmission shaft 61, a spline shaft 62, and a transmission seat 63. The transmission shaft 61 is rotatably installed at the axis center of the rotating seat 31. The transmission shaft 61 and the transverse connecting shaft 415 are respectively fixed with a reversing bevel gear A611 and a reversing bevel gear B4151 that are kept in meshing. Two groups of transmission seats 63 are rotatably installed on the traveling trolley 1. The two groups of transmission seats 63 are respectively coaxially arranged with the two groups of rotating seats 31. The spline shaft 62 is coaxially fixed on the transmission shaft 61. The spline shaft 62 and the transmission seat 63 are kept in sliding connection. Two groups of synchronous wheels A232 are fixed at the bottom of the main screw 23, and a synchronous wheel B631 is fixed at the bottom of the transmission seat 63. The two groups of synchronous wheels A232 are respectively connected to the two groups of synchronous wheels B631 through two groups of synchronous belts to achieve power connection.

[0100] When the main screw 23 rotates, it drives the two sets of synchronous wheels A232 thereon to rotate synchronously, and then drives the synchronous wheels B631 and the transmission seat 63 on both sides to rotate synchronously through the synchronous belt. The transmission seat 63 is rotatably installed on the assembly wing plate 211 of the fixed bracket 21 and the traveling trolley 1.

[0101] During the lifting and lowering operation of the lifting bracket 22 and the rotating seat 31 thereon, the spline shaft 62 and the transmission seat 63 always maintain a power connection, so that the power of the transmission seat 63 is transmitted to the transverse connecting shaft 415 through the spline shaft 62, the transmission shaft 61 and the meshing reversing bevel gears A611 and B4151, and the transverse connecting shaft 415 can drive the auxiliary screw 414 to operate stably.

[0102] Since the transmission shaft 61 is rotatably mounted at the axis of the rotating base 31 , when the reversing assembly 3 and the lifting assembly 2 operate independently, they will not cause motion interference to each other.

[0104] See also Figure 8-14 In order to ensure a stable supply of clean water and cleaning agent to the main spray pipe 43 and the auxiliary spray pipe 44 and to ensure that the inner sleeve 45 can be stably assembled on the main bracket 41, the following technical solution is provided.

[0105] A water inlet is provided at the top port of the main spray pipe 43 , a connecting seat 451 is fixedly connected to the inner sleeve 45 , the connecting seat 451 is fixedly installed on the vertical bracket 412 , and a water inlet is provided at the top end of the inner sleeve 45 .

[0106] The water inlet and the water inlet are used to connect the water supply pipe, and the water supply pipe supplies clean water or cleaning agent to the main spray pipe 43 and the inner sleeve 45, and the clean water or cleaning agent in the inner sleeve 45 is further supplied to the auxiliary spray pipe 44.

[0107] A tow cable rack is also installed on the outside of the steel frame channel 5, or the tow cable rack is directly installed on the wall, so that water pipes, cables, air pipes and other components can swing back and forth when the traveling trolley 1 moves.
