Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance equipment, in particular to a cleaning device for road engineering. Background Technique

[0002] Due to the influence of sunlight, rain, dust adhesion, etc., road markings are contaminated to varying degrees, resulting in unclear road markings, which can easily cause traffic accidents. In order to keep the guiding and directing functions of urban road markings good, it is necessary to clean or re-mark the markings regularly.

[0003] At present, the existing cleaning methods are mainly the following two: one is to manually hold a spray gun for flushing, and the other is to use a more complex cleaning vehicle for cleaning. For the first method, its operation depends on manual labor, which increases the working intensity of sanitation workers and has certain risks. For the second method, it is more resource-consuming because the cleaning work of road markings is not a long-term daily operation. The complex equipment structure will result in high costs, and the equipment is idle for a long time, resulting in low equipment utilization rate and low economy and practicability; at the same time, for the existing cleaning vehicles currently, during the cleaning process, the sewage generated by cleaning cannot be effectively treated, so it will cause sewage to flow everywhere, which not only reduces the cleaning efficiency, but also makes the sewage easily carry other impurities on the road surface and flow into the sewer, and thus is very likely to block the sewer for a long time.

[0004] In addition, the existing cleaning equipment cannot be adjusted according to the widths of different road markings for cleaning, resulting in low cleaning efficiency and poor cleaning effect. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 5, this embodiment provides a cleaning device for road engineering, including a frame 1 and a control device 9. Downward-facing brush guards 2 are respectively provided on both sides of the bottom of the frame 1, and the two brush guards 2 are distributed in an inverted V shape; a high-pressure water cleaning component 3 for spraying high-pressure water to clean the marking line is provided at the larger opening of the two brush guards 2, and a sewage collection component 4 for sucking sewage is provided at the smaller opening of the two brush guards 2. A polishing and cleaning component 5 for polishing and cleaning the surface of the marking line is provided between the high-pressure water cleaning component 3 and the sewage collection component 4; a first lifting mechanism 6 and a second lifting mechanism 7 are provided at the bottom of the frame 1. The movable end of the first lifting mechanism 6 is connected to the polishing and cleaning component 5 to realize the lifting of the polishing and cleaning component, and the movable end of the second lifting mechanism 7 is connected to the sewage collection component 4 to realize the lifting of the sewage collection component; the high-pressure water cleaning component 3 includes a horizontally distributed water spraying pipe 31 and a number of high-pressure nozzles 32 installed at intervals along the side wall of the water spraying pipe 31. A water storage tank 35 is provided at the top of the frame 1. The water spraying pipe 31 is connected to the water storage tank 35 through a water supply pipeline 33, and a first water pump 34 is installed on the water supply pipeline 33. The frame 1 is provided with an adjustment component 11 for driving the water spraying pipe 31 to rotate. The two brush guards play a role in converging sewage and preventing sewage from flowing outwards. First, use high-pressure water to wash the marking line, and then use the polishing and cleaning component for polishing and cleaning, which has a good cleaning effect, and suck and recycle the sewage generated during the cleaning process to avoid sewage flowing across; at the same time, by setting the adjustment component, the water spraying pipe can be rotated to adjust the width range of its water spraying and flushing, so as to effectively clean marking lines of different widths and improve the cleaning efficiency.

[0028] In some specific embodiments, refer to Figures 2 to 4 , the adjustment component 11 includes a servo motor 111, an adjustment rotating shaft 112, and a fixing ring 113. The servo motor 111 is connected to the frame 1. The adjustment rotating shaft 112 is vertically distributed. The upper end of the adjustment rotating shaft 112 is connected to the output shaft of the servo motor 111, and the lower end of the adjustment rotating shaft 112 is connected to the fixing ring 113. The fixing ring 113 is connected to the middle part of the water spraying pipe 31. By starting the servo motor, the water spraying pipe can be driven to rotate forward and backward, so as to well adapt to cleaning marking lines of different widths.

[0029] In some specific embodiments, refer to Figures 1 to 3 , the sewage collection component 4 includes a sewage collection cover 41 with a negative pressure suction port. A water collection tank 42 is provided at the top of the frame 1. The sewage collection cover 41 is connected to the water collection tank 42 through a telescopic hose 43, and a second water pump 44 is connected to the telescopic hose 43. By starting the second water pump, a suction force can be generated, so as to suck the sewage converged at the sewage collection cover and transfer it to the water collection tank for collection.

[0030] As an improved implementation manner, such as Figure 3 shown, a vertically distributed partition plate 421 is arranged in the inner cavity of the water collecting tank 42. The partition plate 421 divides the inner cavity of the water collecting tank 42 into a first cavity 422 and a second cavity 423. The bottoms of the first cavity 422 and the second cavity 423 are communicated; the water collecting tank 42 is provided with a sewage filtering structure, and the sewage filtering structure includes a filter mesh cover 424 and a filter packing layer 425. The filter mesh cover 424 is arranged at the upper part of the first cavity 422, and the filter packing layer 425 is arranged at the middle and lower parts of the second cavity 423. In this way, the sewage is first preliminarily filtered by the filter mesh cover in the first cavity. The filtered water body flows into the lower part of the first cavity, and after standing and sedimentation, it flows into the second cavity from the lower part of the water collecting tank, so as to further filter the water during the upward flowing process of the filter packing layer to obtain clean and clear water.

[0031] In some specific implementation manners, the filter packing layer 425 includes an upper support mesh plate, a lower support mesh plate, and a filter adsorption material located between the upper support mesh plate and the lower support mesh plate.

The reflux assembly 8 includes a reflux pipeline 81 and a third water pump 82 arranged on the reflux pipeline 81. One end of the reflux pipeline 81 is connected to the upper part of the second cavity 423, and the other end of the reflux pipeline 81 is connected to the upper part of the water storage tank 35. In this way, the filtered clean water can be input and refluxed into the water storage tank by the third water pump, improving the utilization rate of water and reducing the waste of water resources.

[0033] In some specific implementation manners, referring to Figures 1 to 3 and Figure 5 , the grinding and cleaning assembly 5 includes a fixing frame 51 and at least one grinding motor 52 installed on the fixing frame 51. The output shafts of each grinding motor 52 are all vertically downward. The output shaft of the grinding motor 52 is connected with a disc brush 53. As an example, two grinding motors and two disc brushes are symmetrically arranged. The rotation directions of the two disc brushes are opposite and both rotate towards the inside, so that the marking line can be better cleaned. During the process of cleaning the marking line, the two disc brushes can push the water towards the direction of the sewage collection cover while rotating and cleaning, avoiding the outward diffusion of sewage.

[0034] In some specific implementation manners, both the first lifting mechanism 6 and the second lifting mechanism 7 are electric telescopic rods. Of course, in some other implementation manners, cylinders or hydraulic cylinders can also be used.

[0035] In some specific embodiments, referring to Figure 1 , on both sides of the frame body 1, there are symmetrically distributed moving wheels 12. The frame body 1 is provided with a handrail frame 13, and the handrail frame 13 is provided with a control switch 91 connected to the control device 9. By operating the control switch on the handrail frame, the operation convenience is improved; by grasping the handrail frame, the cleaning device can be pushed and pulled while cleaning the marking line.

[0036] In some specific embodiments, referring to Figure 1 , the top of the water storage tank 35 has a water filling port 351, which is convenient for replenishing water.

[0037] In some specific embodiments, the blocking brush 2 includes a fixing strip and a plurality of vertically distributed bristles installed on the fixing strip.

[0038] In some specific embodiments, the control device 9 can adopt a PLC control module, which is connected to a power supply, and the power supply can adopt a storage battery.

[0039] Referring to Figures 1 to 5 , during use, by operating the control switch 91, first rotate the water spray pipe 31 according to the width of the marking line, so as to adjust the appropriate cleaning width range; then, start the first lifting mechanism 6 and the second lifting mechanism 7, so as to release the grinding and cleaning assembly 5 and the sewage collection cover 41; after that, start the first water pump 34 to start spraying high-pressure water to wash the marking line, start the grinding motor 52 to drive the disc brush 53 to rotate to clean the marking line, and the formed sewage flows into the sewage collection cover 41 under the converging action of the blocking brushes 2 on both sides and is sucked into the water collection tank 42 for filtration; by starting the third water pump 82, the filtered clean water can be sucked and returned to the water storage tank 35 for reuse.
