Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a large vehicle cleaning system. Background Technology
[0002] Large vehicles include general passenger vehicles, medium-sized buses, and large special-purpose vehicles. To maintain the cleanliness and appearance of the vehicles and to ensure safety, they need to be washed regularly to clean areas covered with mud and other materials, such as the exterior surfaces and headlights, so as not to affect the driver's vision. Moreover, mud obscuring license plates and reflective markings can also affect other vehicles' ability to identify and avoid them; oil or corrosive substances can also accelerate tire aging.
[0003] For large vehicles, manual washing, while achieving a better finish in hard-to-reach areas, is inefficient, time-consuming, and labor-intensive. While automatic car washes, such as the common tunnel-type machines, can automatically spray and wash, these standardized automatic car washes cannot be directly applied to large vehicles. Even with size modifications, the standard cleaning process remains relatively simple and inflexible. For example, a roller brush cannot reach many areas, especially the tires of construction vehicles, which are prone to accumulating mud and oil, making it difficult for a single roller brush to effectively clean them.
[0004] Therefore, this utility model provides a large vehicle cleaning system that modifies the integrated roller brush cleaning process, focusing on cleaning the lower parts of the vehicle and improving the cleaning effect of the tires and other lower structure parts. Utility Model Content
[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a large vehicle cleaning system.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A large vehicle cleaning system includes a mobile gantry frame. Vertical brush assemblies and wheel brush assemblies that can be driven to rotate are spaced apart on both sides of the inner wall of the gantry frame. Hydraulic assemblies are provided between the vertical brush assemblies and wheel brush assemblies and the gantry frame. The hydraulic assemblies control the vertical brush assemblies and wheel brush assemblies on both sides to move closer or further apart. Multiple nozzles with valves are provided on the front and rear sides of the upper end of the gantry frame and on the two side walls between the vertical brush assemblies and wheel brush assemblies. Multiple sets of blowers are provided on both sides and the top wall of the inner wall of the gantry frame. Electric heating wires are provided in the air outlet of the blowers.
[0008] Preferably, it also includes a height-adjustable horizontal brush assembly.
[0009] Preferably, the gantry frame is provided with multiple sets of trusses, each with a pulley block installed at its upper end. A winch is installed at the upper end of the gantry frame, and two stacked lifting straps are wound on the traction sheave of the winch. One lifting strap is wound around the pulley block near the winch and then docks with the end of the horizontal brush assembly near the winch. The other lifting strap is wound around the pulley block away from the winch and then docks with the end of the horizontal brush assembly away from the winch.
[0010] Preferably, guide pulleys are provided on both sides of the inner wall of the gantry near the upper end for vertical traction and guidance of the two sets of hoisting belts.
[0011] Preferably, the nozzles are divided into water gun nozzles with duckbill blades, atomizing nozzles, and PA nozzles.
[0012] Preferably, it also includes a vertical frame set on the side of the gantry and along the moving trajectory of the gantry, and the vertical frame is provided with a drag chain that cooperates with the gantry.
[0013] Preferably, the support frame is equipped with a water-blocking curtain.
[0014] Compared with the prior art, this utility model provides a large vehicle cleaning system with the following advantages:
[0015] 1. Compared with the vertical brush in the traditional tunnel car wash machine, this utility model is also equipped with a smaller wheel brush, and the contact between the wheel brush and the wheel is controlled by a hydraulic assembly, which is specifically used to clean the local area of the wheel, thereby improving the cleaning effect on the tire.
[0016] 2. In this utility model, an electric heating wire is counterweighted in the air outlet of the blower to form a hot air drying system, thereby improving drying efficiency.
[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-9 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0029] Example 1: In order to improve the overall cleanliness of large vehicles, especially the cleaning of the tire area, this example provides a large vehicle cleaning system, including a mobile gantry 1.
[0030] The gantry frame 1 is constructed from welded stainless steel, forming a portal-shaped structure. The overall frame height of gantry 1 is suitable for most large vehicles. For a single type of vehicle, such as a truck, the height is typically 2.2-4.5 meters. Therefore, the internal height of gantry 1 only needs to accommodate the vehicle's height and the retraction space of the cleaning system. Stainless steel sheet metal is welded or bolted to the outer surface of the gantry frame 1, forming an outer shell. Boxes are located on both sides of this outer shell, serving as toolboxes and control cabinets.
[0031] The gantry frame 1 is equipped with a heavy-duty rail-mounted system, including drive assemblies 2 located on the front and rear sides of the lower ends of both sides of the gantry frame 1, and steel rails 3 mounted on the foundation in a forward and backward direction. (See attached diagram.) Figure 8 As shown, the drive assembly 2 includes a wheel frame fastened to the gantry frame 1. A geared motor is bolted to the wheel frame. A bearing housing is located at the bottom of the gantry frame 1, and the axle of a double-flanged wheel is embedded in the inner ring of the bearing within the bearing housing, allowing the double-flanged wheel to rotate. The double-flanged wheel is mounted on a rail 3, allowing it to move only along the rail 3. Sprockets are mounted on the output shaft of the geared motor and on the axle of the double-flanged wheel, with chains mounted on the two sprockets. The geared motor drives the double-flanged wheel to rotate in both directions, thus moving the gantry frame 1 back and forth. The chain drive is tensioned. The bearing housing in the attached diagram can be adjusted up and down by tightening bolts and nuts to adjust the center distance; alternatively, an idler pulley can be directly installed on the wheel frame for tensioning. Alternatively, the output shaft of the geared motor can be directly connected to the axle of the double-flanged wheel via a coupling for direct drive output.
[0032] The inner walls of both sides of the gantry 1 are equipped with rotatable vertical brush assemblies 4 and wheel brush assemblies 5. The height of the vertical brush assembly 4 is close to the height of the internal space of the gantry 1 to meet the washing requirements of the sides of the vehicle that can pass through the gantry 1. The wheel brush assembly 5 is lower, not exceeding 1 / 2 the height of the vertical brush assembly 4. The vertical brush assembly 4 and the horizontal brush assembly 8 have the same structure, only differing in size.
[0033] Hydraulic assemblies 6 are provided between the vertical brush assembly 4 and the wheel brush assembly 5 and the gantry frame 1. The hydraulic assemblies 6 control the vertical brush assembly 4 and the wheel brush assembly 5 on both sides to move closer or further apart. The hydraulic assembly 6 includes two sets of deflection frames 601 and hydraulic rods 602. The two sets of deflection frames 601 are rotatably mounted on the gantry frame 1 through bearing seats. A second reduction motor is also fixed on the upper deflection frame 601. The output end of the second reduction motor is connected to the brush shaft, thereby driving the brush body to rotate for brushing. The two sets of deflection frames 601 are respectively set at both ends of the brush shaft of the vertical brush assembly 4 or the wheel brush assembly 5 and are rotatably connected to the brush shaft through bearings, thereby completing the deflection mounting base of the vertical brush assembly 4 or the wheel brush assembly 5. The fixed end of the hydraulic rod 602 is rotatably mounted on the gantry 1 via a bearing seat, and the movable end is rotatably connected to the non-end part of the upper deflection frame 601. Then, the extension of the hydraulic rod 602 controls the deflection of the vertical brush assembly 4 and the wheel brush assembly 5, thereby realizing the approach and separation of the vertical brush assembly 4 and the wheel brush assembly 5 on both sides.
[0034] Multiple nozzles 16 are installed on the front and rear sides of the upper end of the gantry frame 1, as well as on the two side walls between the vertical brush assembly 4 and the wheel brush assembly 5. Each nozzle 16 is connected to a pipe, and an electric valve is installed at the interface between the pipe and the nozzle 16 to control the opening and closing of the nozzle 16. Different tanks are connected to the pipes, which are externally mounted on the foundation or directly mounted on the gantry frame 1 (but this increases the load on the gantry frame 1 and makes water replenishment inconvenient during movement). The different tanks are used to store clean water, detergent, and softener / cleaning foam, respectively. A pump is also installed between the tanks and the pipes for high-pressure delivery.
[0035] Multiple blowers 15 are installed on both sides and the top wall of the inner wall of the gantry frame 1, and electric heating wires are installed in the air outlet of the blower 15.
[0036] Based on the above technical solution:
[0037] During operation, the vehicle is locked in place on the grid plate between two steel rails 3. Then, the drive assembly 2 starts, moving the gantry 1 back and forth along the steel rails 3. The first back-and-forth movement sprays water to wet the vehicle body; the second movement sprays detergent and softener to soften stains; the third movement drives the hydraulic assembly 6 to deflect and press the vertical brush assembly 4 against the sides of the vehicle body for scrubbing. During this movement, the hydraulic assembly 6 also moves to a position in front of the wheels, driving the wheel brush assembly 5 to deflect and press against the wheels for scrubbing. This scrubbing process can be repeated multiple times. After scrubbing, clean water is sprayed to rinse the vehicle clean. Finally, the blower 15 is activated to provide high-pressure air, blowing away and drying the water droplets on the vehicle surface. The electric heating wire can also be activated to create a hot air system, achieving a drying effect and reducing water residue that could cause watermarks. After cleaning, the equipment is reset, and the vehicle can drive away.
[0038] Example 2 includes large vehicles, including buses, whose roofs require washing, and truck cab roofs also require washing. Therefore, in this example, a retractable horizontal brush assembly 8 is provided. When the roof needs washing, the horizontal brush assembly 8 lowers and rests against the roof to wash it.
[0039] To achieve the lifting and lowering of the horizontal brush assembly 8, the gantry frame 1 has multiple sets of front-to-back trusses, each with a pulley block 10 bolted to its upper end. The attached diagram shows three sets of pulley blocks 10. A winch 9 is mounted on the upper end of the gantry frame 1, with two stacked lifting straps 11 wound around its traction sheave. One lifting strap 11 winds around the pulley block 10 closest to the winch 9 and connects to the end of the horizontal brush assembly 8 closest to the winch 9. The other lifting strap 11 drapes over all the pulley blocks 10 and winds around the pulley block 10 furthest from the winch 9 before connecting to the end of the horizontal brush assembly 8 furthest from the winch 9. By simultaneously winding the two sets of lifting straps 11 by the traction sheave of the winch 9, both ends of the horizontal brush assembly 8 are lifted synchronously, thus achieving the lifting and lowering of the horizontal brush assembly 8.
[0040] Alternatively, two sets of vertical hydraulic rods 602 can be installed on both sides of the horizontal brush assembly 8 for driving lifting. However, these hydraulic rods 602 need to be inverted and extend upwards excessively, which increases the overall installation space requirements of the equipment.
[0041] In this embodiment, guide pulleys 12 are provided on both sides of the inner wall of the gantry frame 1 near the upper end for vertical traction and guidance of the two sets of lifting belts 11, so that both ends of the horizontal brush assembly 8 receive vertical lifting force.
[0042] In this embodiment, the bearing seats at both ends of the horizontal brush assembly 8 are fastened with slide seats 13 by bolts, and the inner side of the gantry 1 is provided with a vertical slide rail 14. The slide seats 13 are slidably mounted on the slide rail 14 to guide the lifting and lowering of the gantry and prevent the horizontal brush assembly 8 from deviating.
[0043] In this embodiment, the accompanying drawings show that the brush shaft of the horizontal brush assembly 8 is directly driven by a reduction motor fixed on the slide block 13.
[0044] Example 3, a further embodiment of this solution, wherein several of the nozzles 16 are divided into water gun nozzles 16 with duckbill blades, atomizing nozzles 16 and PA nozzles 16, which are respectively connected to tanks storing clean water, detergent, and softener / cleaning foam agent, and are used to spray clean water, atomized detergent and clump foam agent.
[0045] In a further embodiment of this solution, Example 4 includes a support frame 17 disposed on the side of the gantry frame 1 and along the moving trajectory of the gantry frame 1. The support frame 17 is equipped with a drag chain 7 that cooperates with the gantry frame 1. In this case, the wiring of each electrical device on the gantry frame 1 passes through the drag chain 7 and connects to the outside along the support frame 17, making the external wiring connection more aesthetically pleasing and neat.
[0046] The pipe connected to the nozzle 16 is clamped and fixed on the gantry 1 by a clamp; the hose extending outside the gantry 1 is a flexible hose, which can be installed in the cable chain 7 and guided by the cable chain 7 to prevent the pipe from becoming tangled.
[0047] Alternatively, drag chains 7 can be installed on both uprights 17 on both sides, with one drag chain 7 used to guide the line and the other drag chain 7 used to guide the pipeline, thus separating the installation to avoid water leakage and short circuit when the lines are installed in an intersecting manner.
[0048] In this embodiment, the support frame 17 is equipped with a water-blocking curtain. This prevents excessive splashing during car washing, thus creating an isolated space.
[0049] In Example 5, a further embodiment of this solution, each blower 15 is equipped with an air guide hood. There are an even number of air guide hoods, symmetrically divided into two groups, with the two groups facing opposite directions. The upper group of air guide hoods faces upwards at an angle, and the lower group faces downwards at an angle. Compared to a horizontal arrangement, this disperses and swells the airflow, resulting in better water droplet dispersion.
[0050] Preferably, the air deflector can be oriented in the direction of travel so that the wind blows obliquely toward the vehicle surface, blowing the water column on the vehicle surface away from the dry side instead of surging to the other side, resulting in a better drying effect.
[0051] The attached diagram in this solution shows a cleaning system designed for passenger buses. For other types of vehicles, other models can be selected. The vertical dimensions of the gantry 1 and the supporting facilities of different models are different to make it suitable for various vehicle types.
