Description

Technical Field

[0001] This utility model relates to the field of automatic car wash technology, and in particular to a tunnel-type single-side drive car wash system. Background Technology

[0002] With the increasing number of car owners, automatic car wash machines, as a new type of car washing equipment, are becoming increasingly popular. Automatic car wash machines offer advantages such as fast washing speed and no damage to the vehicle's surface, saving labor costs for car wash shops and freeing up manpower. A conveyor-driven tunnel-type car wash machine involves the conveyor carrying the vehicle through the tunnel entrance. At this point, a photoelectric sensor is blocked, triggering a signal. The computer PLC processes the signal and issues instructions. Within a certain time frame, the car wash brushes rotate, high-pressure water is used for rinsing, foam is sprayed, wax is applied, and the vehicle is dried by a blower before reaching the exit, completing the car wash process.

[0003] However, most existing car wash machines use a double-chain conveyor to drive vehicles passively inside the machine. The two chains are connected by push rollers for driving. When a vehicle enters the conveyor, it must enter at the right time to avoid the wheels pressing on the push rollers. That is, the vehicle enters the conveyor between the two push rollers. The vehicle being washed needs to time its entry precisely, otherwise it will cause the vehicle to bounce, giving the driver a bad experience. Choosing the right time is essentially waiting, which wastes time. At the same time, when the vehicle is conveyed to the exit of the car wash machine, the front wheels have already left the conveyor. The next push roller needs to push the rear wheels of the vehicle to complete the washing process, causing the washing process to stop and become unsmooth.

[0004] Meanwhile, the car wash machine has two conveyors installed side by side, which results in a large amount of construction work, high investment costs, and a large amount of operation and maintenance work.

[0005] Therefore, how to provide a tunnel-type single-sided drive car wash system that uses a single-rail single-chain conveyor and combines it with a limit bar on the other side to complete the automatic operation of the vehicle washing process, thereby effectively reducing construction costs, has become a technical problem that urgently needs to be solved by those skilled in the art.

[0044] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0045] like Figure 1-10 As shown, a tunnel-type single-sided drive car wash system includes multiple sets of support frames 1, a horizontal drive unit 2, an upper track 4, a lower track 10, a vehicle descending conveyor outlet section 5, and a vehicle ascending conveyor inlet section 6. The vehicle descending conveyor outlet section 5, the multiple sets of support frames 1, and the vehicle ascending conveyor inlet section 6 are sequentially arranged and connected to form a conveyor line. The upper track 4 and the lower track 10 are installed on the inner side above and below the support frame of the conveyor line, respectively. The horizontal drive unit 2 is located on one side of the vehicle descending conveyor outlet section 5. A conveyor pusher device 7 is arranged at the center of the upper track 4, and the horizontal drive unit 2 is connected to the conveyor pusher device 7 through a sprocket and chain assembly, driving the conveyor pusher device 7 to rotate and move, thereby moving the vehicle to be washed forward through the tunnel-type car wash chamber.

[0046] like Figure 2-3As shown, the support frame 1 includes a long support frame 1-1 and a short support frame 1-2, and a suitable number of the long support frames 1-1 and short support frames 1-2 are arranged and connected together in sequence. Specifically, the difference between the long support frame 1-1 and the short support frame 1-2 lies in their overall length and the number of intermediate connecting plates 102 used. For example, in a specific embodiment, the long support frame 1-1 is provided with three intermediate connecting plates 102, while the short support frame 1-2 is provided with two intermediate connecting plates 102, and the spacing between adjacent plates is the same or not significantly different.

[0047] Specifically, the long support frame 1-1 and the short support frame 1-2 have similar structures, including a top side wall 101, a middle connecting plate 102, a first lower support beam 103, a base plate 104, an end connecting plate 106, and a second lower support beam 107. The top side wall 101 is fixedly connected to multiple first lower support beams 103 and two second lower support beams 107 via multiple middle connecting plates 102 and two end connecting plates 106, respectively. The base plate 104 is adjustablely connected to both ends of the lower support beam via screws 105, and the height of the base plate 104 is adjustable. The design of the base plate 104 increases the contact area between the support frame and the construction ground, ensuring stability. The screws 105 are threadedly connected to the lower support beams, enabling the height of the base plate 104 to be adjustable. This allows the entire support frame to have an adjustable height to accommodate more positioning slots and effectively address the problem of uneven bottom surfaces of the positioning slots in the car wash.

[0048] Specifically, the end connecting plate 106 has multiple connecting holes 108 from bottom to top, and two adjacent sets of the support frame 1 are fastened together by bolt assemblies, which are installed at the connecting holes 108.

[0049] like Figure 4-5 As shown, the horizontal drive unit 2 includes a horizontal motor 201 and a reducer 202 connected by a transmission. The output shaft of the reducer 202 is connected to the conveyor outlet shaft 701 of the conveyor pusher device 7 via a sprocket and chain assembly 203. A protective cover 3 is provided above the horizontal motor 201. The horizontal motor 201 is mounted on one end of the lower mounting beam, and the other end of the lower mounting beam is connected to the bottom of the outlet support frame 501. An outlet reinforcing bar 502 and an outlet fixing plate 503 are provided at the end of the track of the outlet support frame 501. The use of the horizontal motor 201 reduces the overall height of the device and reduces the space occupied. The height of the protective cover is almost flush with the ground, allowing the horizontal drive unit to be placed inside without affecting the operation of the vehicles to be washed, effectively reducing the width of the overall car wash booth. The protective cover improves the sealing performance, reduces the impact of dust and other contaminants on the horizontal drive unit, and extends its service life.

[0050] Specifically, such as Figure 4 As shown, a counter 9 is installed at the outlet end of the outlet support frame 501. This counter is electrically connected to the control center and can automatically count the number of vehicles being cleaned, facilitating automated management.

[0051] like Figure 5-7 As shown, the conveyor pusher device 7 includes two sets of rollers 705 at the top, a conveyor trolley 704, a conveyor outlet shaft 701, a conveyor inlet shaft 706, and a conveyor chain. The conveyor chain is fitted onto a conveyor drive sprocket 702 and a conveyor driven sprocket 703. The conveyor drive sprocket 702 and the conveyor driven sprocket 703 are respectively mounted on the conveyor outlet shaft 701 and the conveyor inlet shaft 706. The conveyor outlet shaft 701 is rotatably mounted on the conveyor outlet shaft 701. The conveyor inlet shaft 706 is connected to the inlet support frame 601 through a spring tensioning assembly 11. The track end of the inlet support frame 601 is provided with a fixing plate 604 and a flap 603. The flap 603 is rotatably connected to the inner side of the fixing plate 604 through an inlet flap shaft 602. The fixing plate 604 is connected to the inlet support frame 601 by screws. The design of the spring tensioning assembly 11 effectively ensures the tension of the conveyor chain, thereby making the vehicle run more smoothly.

[0052] like Figure 8-10 As shown, the spring tensioning assembly 11 includes a spring 1101, a rear fixing plate 1103, a guide sleeve 1105, a guide shaft 1106, and an inlet shaft fixing bracket 1108. The inlet shaft fixing bracket 1108 is movably connected to the guide sleeve 1105. The rear fixing plate 1103 is positioned and connected to an intermediate connecting plate of the inlet support frame 601 by an adjusting bolt 1102. An adjusting bolt fixing plate 1104 is provided at the nut of the adjusting bolt 1102. The adjusting bolt fixing plate 1104 and the intermediate connecting plate are fastened together by a bolt assembly. The guide shaft 1106 is placed horizontally and one end is positioned and connected to the guide shaft fixing seat 1107. The other end of the guide shaft 1106 passes through an intermediate connecting plate, a guide sleeve 1105, and another intermediate connecting plate and extends out from the rear fixing plate 1103. An anti-disengagement pin is connected in the pin hole at the other end of the guide shaft 1106. Specifically, the adjusting bolt 1102 has an adjusting nut threaded on the side away from the nut. Rotating the adjusting nut causes the rear fixing plate 1103 to move horizontally along the guide shaft 1106, reducing the distance between it and the guide shaft fixing seat 1107. Under the action of the spring force, the inlet shaft fixing bracket 1108 will move horizontally as a whole, thereby causing the conveyor inlet shaft 706 to move synchronously, away from or closer to the conveyor outlet shaft 701, thus quickly realizing the adjustment of the conveyor chain tension and facilitating the assembly of the conveyor chain.

[0053] Specifically, a protective strip 8 is provided on the inner side of the top sidewall of the conveyor line to protect the wheels and prevent scratches and damage.

[0054] How to use this utility model:

[0055] First, assemble it inside the car wash, specifically placing it in the positioning slot on one side of the excavation, and then electrically connect each drive component to the control center;

[0056] Secondly, after sensing the arrival of the vehicle to be washed, the control center will issue a corresponding command, and the horizontal motor of the horizontal drive device will start, driving the conveyor pusher device 7 to work through the reducer and sprocket chain assembly; the conveyor chain of the conveyor pusher device 7 rotates under the drive of the conveyor drive sprocket 702 and the conveyor driven sprocket 703, and then drives the rollers 705 connected above to move linearly through the conveyor trolley 704. There are two sets of rollers 705, one set abutting against the track and the other set abutting against the wheels, thus pushing the vehicle to be washed forward through the tunnel-type car wash room and successfully completing the car wash operation.
