Description

  The present invention uses a fine cleaning material as a cleaning material, a dry cleaning device used for cleaning a painted surface, concrete ground treatment, rust removal on a steel surface, and the like, and the lane mark in a tunnel on a highway mainly. The present invention relates to a road lane mark cleaning method for removing dirt.

  In general, cleaning for the purpose of cleaning the painted surface, surface treatment when casting concrete, removing rust on the surface of steel, etc. is performed by mixing abrasives and detergents made of solid material for cleaning into the liquid agent. The method of brushing the surface is generally used.

  Also, in highway tunnels, exhaust gas and dirt from the road surface are deposited along with oil and accumulated, especially when it becomes difficult to see the lane mark consisting of white lines drawn on the shoulder, the driver identifies the shoulder. It becomes difficult and causes an accident. For this reason, it is necessary to actively clean the surface of this type of lane mark in the tunnel.

  However, since the conventional cleaning device uses a liquid agent, it takes time and cost to remove the liquid agent after cleaning, and the cleaning material after use becomes industrial waste, and the processing cost is very high. There was a problem that it took.

  In particular, lane marks such as white lines and yellow lines that divide traveling sections of expressways are difficult to see if the surface becomes dirty, so it is necessary to clean the lane marks in the tunnel. In addition, beads are mixed in a resin material to be a paint. These beads are used for the purpose of increasing the brightness by reflecting the lights of automobiles, and it is necessary to prevent the beads from being damaged during cleaning. However, with conventional cleaning methods, there is a problem with the treatment of the liquid agent after cleaning. In addition, there is a problem that the beads are damaged and the luminance is lowered.

  In view of such a conventional problem, the present invention provides a dry cleaning device that can easily collect and process a cleaning material after cleaning and has a high cleaning effect, and the surface of a lane mark without using the beads to damage the surface. It was made for the purpose of providing a road lane mark cleaning method that can remove dirt.

  A feature of the invention described in claim 1 for solving the conventional problems as described above and achieving an intended purpose is that a cleaning surface cover enclosing a predetermined range including a cleaning surface and forming a space therein. , A vacuum means for sucking air in the cleaning surface cover, and a cleaning material injection nozzle having a tip opened in the cleaning surface cover and injecting finely cleaned cleaning material toward the cleaning surface in the cleaning surface cover Cleaning material supply and injection means for jetting the cleaning material at a high speed from the cleaning material injection nozzle; and dust removing means for removing solid components including the cleaning material from the air in the cleaning surface cover sucked by the vacuum means. The cleaning surface cover is moved along the cleaning surface, and the cleaning material is sprayed onto the cleaning surface from the cleaning material spray nozzle at a high speed to remove deposits on the surface of the cleaning surface. In the cleaning device.

  A feature of the invention described in claim 2 is that, in addition to the structure described in claim 1, the cleaning material is a baking soda having a fine particle shape.

  According to a third aspect of the present invention, there is provided a cleaning surface cover surrounding a predetermined range including a cleaning surface and forming a space therein, a vacuum means for sucking air in the cleaning surface cover, and the cleaning surface cover A cleaning material injection nozzle that has a front end opened therein and that injects the finely cleaned cleaning material toward the cleaning surface in the cleaning surface cover, and a cleaning material supply injection that injects the cleaning material at a high speed from the cleaning material injection nozzle. And a dry cleaning device comprising dust removing means for removing solid components including the cleaning material from the air in the cleaning surface cover sucked by the vacuum means, and the cleaning surface cover of the dry cleaning device is used as a road By moving along the surface of the lane mark drawn by applying a beaded paint on the surface, using finely divided baking soda as the cleaning material, and spraying the cleaning material onto the surface of the lane mark In the road lane mark cleaning method for removing the dirt surface Te.

  In the present invention, in the cleaning surface cover including a predetermined range including the cleaning surface, a solid cleaning material is sprayed from the nozzle onto the cleaning surface, and the dust in the cover is sucked by the vacuum means. Because the cleaning material does not leak to the surroundings, the entire amount is collected together with the dirt removed from the cleaning surface, and it can be separated almost completely from the air by dust removal means using the same cyclone that is commonly used. The generation of industrial waste can be minimized.

  In addition, by using powdered baking soda as a cleaning material, the oil content on the concrete surface and steel surface can be removed suitably, the surface treatment of the concrete surface, the removal of graffiti on the concrete wall, the oil content and rust on the steel surface. Effective for dropping.

  Furthermore, by using this for cleaning lane marks on highways, etc., the road can be used immediately after passing through this device, so the road closure time for cleaning is extremely short, and the traffic situation is not deteriorated. The work can be performed, and the beads contained in the lane mark paint are not damaged. Therefore, the lane mark having substantially the same brightness as that when the new paint is applied can be restored.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  FIG. 1 shows an outline of the entire apparatus of the present invention. In this apparatus, a cleaning head unit 2 is mounted on a carriage 1. The carriage 1 is provided with wheels 3 at the four corners of the bottom so that it can run on a cleaning surface such as a road.

  The cleaning head unit 2 has a cleaning surface cover 4 that covers a certain area on the cleaning surface A. The cleaning surface cover 4 has a box shape with an opening facing downward, and a cylindrical peripheral wall portion 4a that hangs downward around the four circumferences, and a downwardly funnel-shaped upper surface covering portion 4b that closes the upper portion. And a space is formed inside.

  As shown in FIG. 2, a peripheral edge shielding plate 5 made of a rubber plate is suspended downward from the periphery of the opening of the cleaning surface cover 4. On the outer side of the peripheral edge shielding plate 5, a brush 6 that is continuous along the arrangement is suspended. The peripheral shielding plate 5 and the brush 6 have an auxiliary piece 7 hanging parallel to the inside of the peripheral wall portion 4a, and the upper end side is inserted into a groove between the auxiliary piece 7 and the peripheral wall portion 4a and screwed. When the carriage 1 is placed on the cleaning surface A, the lower ends of the peripheral oblique side plate 5 and the brush 6 are in elastic contact with the cleaning surface A. In addition, a plurality of vertically oriented long holes 8 are formed in the peripheral wall portion 4a.

  In the cleaning surface cover 4, an intermediate partition 8 (shown in FIG. 1) that partitions a lower space portion surrounded by the peripheral wall portion 4 a in the front-rear direction is installed at a portion about 1/3 of the front side.

  On the rear side of the cleaning surface cover 4, a cleaning material injection nozzle 10 is inserted obliquely forward and downward on the treetop. This cleaning material injection nozzle 10 is formed in a taper shape having a distal end opening 10a that expands into a flat oblong shape, and a cleaning material supply / injection means communicates with the proximal end side. This is composed of a compressor 11 and a cleaning material supply device 13, and a pneumatic feed path 12 communicating with the compressor 11 is communicated with the cylindrical portion 10 b of the cleaning material injection nozzle 10, and the cleaning material supply device 13 is connected to a tip portion of the pneumatic feed path 12. The cleaning material supply path 14 is open to communicate with the branched arrangement. The cleaning material supply device 13 is configured by connecting a cleaning material supply path 14 via a valve 17 capable of quantitatively discharging the cleaning material from the lower end of a cleaning material tank 16 that accommodates the cleaning material B made of fine particles. The cleaning material B is sucked out by the negative pressure generated in the cleaning material supply path 14 by supplying the compressor 11 high-pressure air to the pneumatic supply path 12 and supplied to the nozzle 10 side.

  A vacuum means communicates with the top of the cleaning surface cover 4. This vacuum means comprises a vacuum pump 20 having a suction port communicating with the top of the cleaning surface cover 4. The discharge-side flow path of the vacuum pump 20 is opened to the atmosphere through the dust removing means.

  The dust removing means is composed of a cyclone 22 and a dust collecting tank 23, and the air in the cleaning surface cover 4 is sent to the cyclone 22 at high speed through the hose 21, where dust is removed by centrifugal force and the air is released into the atmosphere. In addition, the removed dust is stored in the lower dust collection tank 23.

  When using the dry cleaning apparatus configured as described above, for example, when cleaning the lane mark C drawn in the tunnel of the expressway, the cleaning material tank 16 has a diameter of about 100 μ to 300 μm as the cleaning material B. As shown in FIG. 1, the carriage 1 is placed so as to straddle the Ren mark C and can be moved along the same. And the vacuum pump 20 sucks the air in the cleaning surface cover 4. The sprayed cleaning material B collides with the surface of the lane mark and is pulverized into a fine powder, and peels off the dirt including oil on the surface of the lane mark. The dirt peeled off in this way is scattered in the cleaning surface cover 4 together with the cleaning material after jetting, sucked together with air by the vacuum pump 20, put in the cyclone 22, separated into air and dust, and a dust collecting tank. 23.

  In this way, when cleaning the surface of the road lane mark, by using baking soda fine particles as a cleaning material, it does not damage the beads for demonstrating the brightness mixed in the paint, depending on the smoke particles and oil on the surface Dirt can be removed cleanly, and cleaning is performed in a cleaning surface cover that is blocked from the outside, and all the dust after cleaning is sucked by the vacuum, so it can be quickly cleaned without damaging the surrounding environment Can be carried out.

  In addition, the use of dry fine-grained cleaning materials makes it possible to easily separate and remove dust sucked together with air by vacuum, and significantly reduces the amount of industrial waste generated compared to wet cleaning using detergents. it can.

  In the above example, the road lane mark has been described. However, the apparatus according to the present invention can also be used for concrete ground treatment, removal of graffiti on the concrete surface, rust removal on the steel surface, and the like. Moreover, the cleaning material to be used can select and use other materials, such as sand, a hard or soft resin fine particle material suitably according to the cleaning object.
