Description

Pavement lane cleaning method {PAVEMENT LANE CLEANING METHOD}

The present invention provides a lane cleaning method for quickly and cleanly cleaning a contaminated line of various lines such as an automobile pavement or other (airway guide line of a runway, guide line of a square, etc.) at low cost. On the general pavement, the lanes are drawn with yellow lines or white lines to prevent safety accidents, but the lanes themselves are contaminated with various pollutants and the color is not changed or vivid. As the condition is maintained, especially at night, it caused a safety accident and inconvenience when driving a car, and relates to a lane cleaning method for pavement to prevent such a problem.

Tire lanes, dust, sand, and snow types (such as snow and ice) generated by road brakes or airport runways that have not been managed so far in the past, such as when a car is braked or a plane lands. Even if you are contaminated with paints or mud, cement or asphalt, and other types of stains when entering or going to the construction site, you have to leave it until you repaint it. It was.

Repainting contaminated lanes or plane guides, etc., could not be repainted every time due to budgetary shortages. Moreover, as the number of lanes increases, the number of cases of leaving contaminated lanes increases, but until now, even in developed countries, they have not found a solution in terms of cleaning technology and cost.

Accordingly, the present invention is simple and low-cost quickly by grinding (cutting only to clean only the contaminated surface) or stamping (cleaning only to clean the contaminated surface) using a grinding machine (cutting only). It is an object of the present invention to provide a lane cleaning method for maintaining the clearness of the lane.

Therefore, the main body 1 is configured to be used to replace the vertical rotary grinding (cutting) blade 12 and the horizontal rotary grinding (cutting) blade 27 according to the purpose of convenient use.

Fig. 7 is a principle diagram of a lane surface grinding (cutting) method according to the present invention, where "a" is a principle of a method of working by mounting the types of vertical rotary grinding (cutting) blades 12 as an example.

Contaminants 30, 31, and 32 contaminated in the lanes 33 drawn on the surface layer 34 of the pavement are first removed by the horizontal brush 13 to remove the fluid contaminants (30-types of garbage). Sedimentary contaminants (31-one example; mud, cement, ice and snow, asphalt etc.) are scraped off by the blade 14 and are removed from the surface of the lane 33 (32-one example; tire marks, dust, etc.). , Oil, paint, stinging, etc.) is a grinding (cutting) blade (12) is a principle of grinding (cutting) by only peeling off or wiping only the dirt on the surface.

When the cleaning operation reduces the frictional heat generated on the rotating grinding blade 12, the blades that are weak to heat are sprayed 28 to protect them from the generated heat. The dust was collected in the dust collecting container as the dust collecting device 86 through the dust collecting suction number 4 through the dust collecting suction port 5.

"I" is the same as "A", but using the type of horizontal rotary grinding (cutting) cutting edges (27) instead of the vertical rotary grinding (cutting) blade (12) in the example of "A" to obtain the same effect as "A" to be. This is because the lanes sometimes have irregularities and ups and downs, so that you have to work properly using methods such as "a" and "me" to get a precise and good effect. Therefore, when only the surface of the lane 33 contaminated with the contaminants 30, 31, and 32 for the purpose of cleaning the lane 33 is ground (cut) as described above, the lane 33 is clearly exposed. It's a principle.

Here, the grinding (cutting) part is only to wipe off the extremely thin contaminated surface as much as necessary, so that there is little effect on the lane 33.

Figure 8 shows another example of the grinding (cutting) machine according to the present invention, "d" is a device for rotating the grinding (cutting) blades (27 <1>, 27 <8>) by an electric motor. "D" means that the small internal combustion engine 40 is installed to rotate the grinding (cutting) blades 27 <1> and 27 <8>.

For this reason, the maneuverability is good in a narrow space, the operation of the cleaning vehicle according to the present invention is inconvenient or not working, such as a small safety zone line or crosswalk, where the efficiency is low, such grinding (cutting) machine ( C) the cleaning workers directly use it to ensure rapid cleaning.

9 is an exploded perspective view of "d" as an example to help understand the grinding machine in FIG. 8, wherein two posts 46 and 47 having bolt holes 45 are coupled to the grinding machine. In the center, the nut 50, the left and right hollow hollow shaft 48 and the hollow longitudinal axis 49, the bracket 51 for mounting the electric motor 42 <1> and the hollow spindle ( 48 has a crosshead to which a gear 41 <1> is fixed.

In addition, there is an angular bolt 44 to which the gear 41 is coupled and an electric motor 42 equipped with the gear 41 <1> to move the crosshead composed of the hollow spindle 48 and the hollow longitudinal axis 49 up and down. It is configured to be.

In addition, a rotating plate 57 is formed, and a plurality of gears 41 <3> to 41 <10> and bearings 52 <2> to 52 <17> and 53 <1> to 53 <16> therein. The internal gear facilitates the rotation of the gears.

In addition, a number of small grinding (cutting) blades (27 <1>, ~ 27 <8>) are bound by the chucks (60, 60 <1>, ~ 60 <7>), and the vibration and pressure generated during operation And springs (10 <2> to 10 <9>) are built in to absorb shock.

The rotor plate 57 was sealed with a casing 55 to increase the safety of the parts, while the rotor plate 57 was caused to rotate the electric motor 42 <1> as the belts 59, 59 <1>. .

Here, the pins 54 are formed on the axes of the gears 41 <3> to 41 <10>, which are embedded in the rotary plate 57, and the roles of the pins 54 are chucks 60, 60 <1>, 60 < 60 >), the pins 54 are formed as space holes 61 that can move up and down, respectively, on the shaft of the chuck to prevent the coupling of the components and prevent the separation.

The grinding (cutting) machine having such a structure is not only composed of the electric motor 42 <1> or the small internal combustion engine 40 but is completed, but also the hydraulic motor 11 is included in the cleaning vehicle which becomes the hydraulic circuit device according to the present invention. Of course it is complete.

FIG. 10 illustrates, by way of example only the pivotal plate 57 of the sectional view taken along the line A-A 'in FIG. 8 to further aid in understanding of FIG.

The driven gears 41 <5> and 41 <9> are built around the main shaft gears 41 <2> bound to the hollow spindle 48 so that the electric motors 42 <1> are belts 59, 59. When rotating the rotary plate 57 as a <1>, the teeth of the driven gears 41 <5> and 41 <9> are caught by the teeth of the main shaft gear 41 <2>, and the driven gear 41 <5> is rotated. Chucks (60 <2>, 60 <4>, 60 <6>), which are subordinate to (41 <9>), are then rotated and thus the grinding (cutting) blades (27 <3>, 27 <7>) which are subordinate together. ) Will also rotate together. At this time, the rotation speed of the grinding (cutting) blades 27 <3> and 27 <7> was configured to be faster than the rotation speed of the rotating plate 57 to increase the work effect.

Here, the wheels 37 <2> mounted on the posts 46 are configured to be located in the center space of the grinding (cutting) blades 27 <3> and 27 <7>, so that they are completely different from the grinding (cutting) blades. It will not interfere or be interrupted, and the grinding blade will be leveled with the surface of the grinding lane. The grinding blade will be used during the grinding of the lane surface (27 <3>). , 27 <7>).

On the other hand, the angular bolt 44 to control the rotating plate 57 up and down during the cleaning operation was to be controlled while being rotated forward and reverse by the electric motor 42.

In addition, a suction lake (4 <1>) is formed to suck dust or other contaminants generated during the cleaning operation into the dust collecting container, and it is necessary to protect some grinding blades (27 <3>, 27 <7>). A water pipe 6 <1> and a nozzle 7 <1> are configured together to reduce the generated frictional heat.

Figure 11 illustrates a number of types as an example to assist in understanding the grinding (cutting) blades according to the present invention, wherein the use of such various types of grinding (cutting) blades in the present invention is a condition of a contaminated lane to be cleaned. This is because a good effect is obtained only by selecting the blade suitable for the purpose according to the condition and the like. This is a very important completion condition in the present invention.

For example, a method of effectively selecting and using a grinding blade such as "e" is effective for removing solidified mud, cement, asphalt, or ice (ice) that has solidified on the lane surface. Grinding blades are ineffective.

However, in the case of tire traces or crushed dust, grinding blades such as "a" are effective, and blades such as "e" are not effective for excessive surface grinding (cutting).

Therefore, the selective use conditions of the grinding (cutting) blade according to the present invention is to appropriately deal with the contaminated lane according to the pollution degree of the lane and the painted period of the lane, so as to obtain the best effect, and therefore various kinds of grinding (cutting) The purpose of the present invention is to achieve the best cleaning effect by selecting and using the blade.

12 shows an example to help understand the rotary plates 62 and 63 according to the present invention, and a plurality of grinding (cutting) blades B, C, and D are spirally formed on the rotary plate 62 of the "car". The grinding (cutting) blades (B, C, D) can have the same effect as in Fig. 11, but the rotating plate 62 of this structure is simple to replace and replace. It is very effective and has the advantage that it can be used in both the grinding (cutting) in Figures 4, 5 and 8.

Spring (10 <10>,-10 <15>) for the protection of grinding blades (B, C, D) during cleaning and for effective grinding (cutting) by buffering irregular irregularities in lanes. Together.

"Ka" is composed of a plurality of rod round bar shaft 64 on the rotating plate 63 and a number of blades (65,65 <1>) on the round bar shaft 64 to the centrifugal force action when the rotating plate 63 is rotated This allows the blades 65,65 <1> to be ground (cut) while rubbing the lane surface.

Here, 65 blades are steel wires made mainly of spring steel or Incheondong, which have good elasticity, and blades of "65 (1)" are composed of diamond, hard stone, or tool steel at the end of the blades. ; Cement, etc.) is to be strongly ground (cut).

Therefore, when arranging the grinding (cutting) blades used in accordance with the present invention, the grinding (cutting) blades used in the present invention, both large and small, according to the cleaning operation conditions as described above to use the best cleaning effect The grinding blades used in the present invention are made of various kinds of brushes including spring steel wire, and tool steel type and abrasive stone made of cemented carbide, ceramic, cermet, diamond, and stubstone. It is made of various grinding wheels and sandpapers, including brush.The type of brush is classified and used according to the thickness and elasticity of the wire, and the edge of tool steel type is saw tooth type, gear type, end mill type or cutter blade type. It is classified into and used as file type and file size, and the specification of abrasive, grindstone and sandpaper particles can be variously different. The lane surface contamination using tack is grinding (cutting). Such a reason is also because it selects the most effective in consideration of the work efficiency due to the loading phenomenon according to the conditions and circumstances to be cleaned, which is a very important condition in completing the present invention as described above. For reference, the rotary plate 57 of FIG. 9 and the rotary plate 62 of FIG. 12 include a plurality of grinding (cutting) blades, which may be used as one type of blade, but may be used as necessary. The grinding (cutting) blade is composed of different configurations can be used to achieve an excellent effect depending on the working conditions. For example, the contaminated lane has been painted for a long time, and the contaminated cleaning conditions caused by malignant contaminants (e.g., soft contaminants <gum type> and solid contaminants <cement type>, etc.) At the same time, the grinding (cutting) blades are composed synthetically, but some of the grinding (cutting) blades are composed by brushing and wiping, and some are composed of tool steel grinding (cutting) blades and soft contaminants. It is used to remove solid contaminants by forming a blade of grinding wheel and diamond, and partly to remove solid contaminants. The effect is better than using it.

In addition, the most important thing is that if you use the blades as described above are not suitable for the purpose does not obtain a clean cleaning effect.

For example, it is necessary to clean lanes contaminated with old tire lanes or oily paint or automotive engine oil, but the brush type is less effective. Therefore, the present invention can achieve the intended effect only by wiping the surface with a grinding wheel (cutting) with a brush while wiping it with a brush. If it is not possible, surface grinding with a tool steel blade will not be effective, as it can only be achieved by wiping the lane surface with a brush blade of moderate strength.

Therefore, the present invention removes and cleans various malignant contaminants, including contaminated new lanes, stray lanes, and the like, according to a certain type of lane, an airplane guide line, a safety line, and the like. It is also a feature of the present invention to obtain excellent cleaning effects by selecting and using various types of grinding (cutting) blades in a timely manner.

Fig. 13 shows an example in which a grinding machine 68 according to the present invention is installed in a cleaning vehicle according to the present invention, and the booms 67, 67 < 1 > 67 on the front and left and right sides of the cleaning vehicle 66. <2>, 67 <3>), and attach the grinding machine 68 to the necessary parts of the cleaning vehicle according to the working conditions (68 <1>, 68 <2>, 68 <). 3>) to use it.

Fig. 14 shows a side view of the grinding machine 68 according to the present invention installed in a cleaning vehicle according to the present invention. As an example, “ta” is an example of the cleaning vehicle 66 shown in Fig. 13 as a side view. As an example, there is a loading box 70 in which various equipments are built, and a warning light is provided to inform cleaning.

"Wave" in the present invention, such as small heavy loaders or other small livestock machinery type for use in small spaces (safe zone line or crosswalk line) or alley where it is inconvenient to clean with a large cleaning vehicle It is the cleaning vehicle completed suitably for invention.

15 is an exemplary view of a hydraulic circuit according to the present invention, in which two hydraulic pumps 74 and 74 <1> are operated by an internal combustion engine 73, but a large hydraulic pump 74 has a grinding (cutting) blade. In order to operate only the hydraulic motor 11 which rotates (12, 27), the motor 11 is configured so as not to receive unnecessary interference in order to operate smoothly and uniformly, and the small capacity pump 74 <1> has the remaining motor. (11 <1>) and the cylinders 15, 15 <1> and 15 <5> were made to operate.

When the internal combustion engine 73 is operated, the pump 74 sucks oil from the oil tank 75 through the filter 76 and ejects the oil at high pressure to rotate the motor 11. It is introduced into the oil tank 75 through 77.

The oil is introduced into the motor 11 in an appropriate amount, but the quality of the flow is controlled by the operator by the solenoid valve 83. At this time, since the oil heat passes through the cooler 78, the oil temperature is maintained at an appropriate temperature and the motor 11 is safely operated.

Here, the pressure reducer 82 is configured to obtain stable hydraulic pressure and to protect the hydraulic device.

On the other hand, the flow rate discharged from the other pump 74 <1> operates the motor 11 <1> and the cylinders 15, 15 <1>, and 15 <5>. 83 <1>, ˜83 <7>), and otherwise, flows into the oil tank 75 through the relief valve 77 <1>.

In order to increase the efficiency of the hydraulic pressure, the pressure reducer 82 <1> is configured here.

In addition, the thermometer 80 and the temperature switch 79 were configured to maintain the proper oil temperature of the oil, and the impeller driving source 86 was collected in the internal combustion engine 73 so as not to install a separate motor.

FIG. 16 shows an example of a direct current (DC) electric circuit according to FIG. 15. When the power is energized, current flows through the fuse 87 so that the solenoid valve 83 is operated according to the operation of the switch 88. .

At this time, the solenoid valve 83 is opened and closed in a required direction by a switch operation.

Part of the current opens and closes the solenoid valve 83 <1> by operating the switches 83 <1> and 88 <2> through the fuse 87 <1>, wherein the motor 11 <1> The rotation angle of the motor 11 <1> was adjusted by opening and closing by the limit switches 88 <3> and 88 <4> provided at positions necessary for the rotation angle of the.

Based on this principle, the circuit of the solenoid valve is to be operated, where the switches (88 <1>, 88 <16>) are all in a square form when one side is excited so that one side is broken so that the two are not operated at the same time.

Here, the cooling fan 89 is operated when the temperature switch 79 is turned on when the set temperature exceeds the set temperature so that the current through the fuse of “87 (8)” is energized by the cooling fan motor 89 to operate. When the temperature switch 79 is turned off, the current of the cooling fan motor 89 is cut off and the operation is stopped.

With the same principle, the spraying motor 90 also turns on the "88 (17)" switch, which causes the current through the fuse 87 <9> to operate the spraying motor 90, and the "88 (17)" switch is turned off. If the power is cut off and the motor 90 is stopped.

Hereinafter, the warning lamps 69,69 <1>, 69 <2> are operated in the same principle.

Fig. 17 is an example of an alternating current (AC) three-phase electric circuit by the generator 91 according to the present invention. The internal combustion engine 73 < 1 > operates the generator 91 to generate a current regulator. And flowed through the circuit breaker 93 at a proper voltage again.

Here, when the switch 88 <21> is turned on to operate the electric motor 42 <1>, the coil 97 of the electromagnetic switch is excited. Therefore, the electromagnetic switch contact 98 of the motor circuit is also turned ON, and the motor 42 <1> rotates.

In addition, when the "96" switch is turned OFF to stop the rotation of the electric motor 42 <1>, the rotation is stopped. However, since the rotation of the electric motor 42 <1> may be delayed by inertia, the counter electromotive force may flow in this case, so the timer 94 is configured to prevent damage by the counter electromotive force.

Here, the rotation speed of the electric motor 42 <1> is configured to be determined by the set speed of the inverter 95.

In addition, when the switch 88 <22> is turned on to operate the watering motor 90, the coil 97 <1> of the electromagnetic switch is excited. Therefore, the electric switch contact point 98 <2> of the motor 90 circuit is also turned on so that the motor 90 rotates. When the "96 (1)" switch is turned off in the operated state, the motor 90 rotates. Is stopped.

As the circuit of the "42" motor, two electromagnetic switches 97 <2> and 97 <3> were used as an example of the forward rotation and the reverse rotation circuits.

The principle of operation is the same as the principle described above. When the " 88 (23) " switch is turned ON, the electric motor 42 rotates forward and the " 96 (2) " switch is turned OFF.

When the "88 (24)" switch is turned ON again, the "97 (3)" electronic switch is excited and the "98 (5)" contact of the motor 42 circuit is turned ON. It will reverse.

To stop the reverse rotation of the electric motor 42, turn off the " 96 (2) " switch to stop the rotation.

In the forward rotation, even if the “88 (24)” switch is operated due to a misoperation, the contact point (99 <1>) is placed in front of the coil of the electronic switch (97 <3>) to form an interlock circuit that serves as a protection circuit against malfunction. did.

It is shown as an example to help understand that the electric circuit in the dashed line can be used with an alternating current (AC) current as a direct current (DC) electrical circuit.

For example, the direct and reverse rotation circuits of a 42 motor using direct current (DC) are constructed. The principle of operation is that current flows through the fuse (87 <17>) and the "88 (25)" switch is turned on. In this case, some electric current is energized by the electric motor 42, and the electric motor 42 performs forward rotation.

At this time, since the "88 (26)" switch is kept OFF, the current flows only toward the forward rotation when the "88 (25)" switch is turned ON.

When the "88 (25)" switch is turned OFF, the forward rotation of the "42" motor is stopped.

On the contrary, when the "88 (26)" switch is turned on to reverse rotation, the current polarity is reversed to the coil of the electric motor 42. Therefore, the "42" motor reversely rotates.

In order to stop the electric motor 42 which has been rotated in reverse, it is stopped by turning off the "88 (26)" switch.

The " 88 (25), 88 (26) " switches here have been configured as the shallow switches described above.

In addition, when you want to turn on the warning lights (69,69 <1>, 69 <2>) at the same time, turn on the "88 (27)" switch and turn off when you want to turn off. It became a circuit.

The direct current (DC) or alternating current (AC) is, of course, used in a variety of necessary circuit configuration as needed.
