Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an apparatus for peeling and removing a road marking such as a white line drawn on a road.

[0002]

[Prior art]

 Conventionally, a cutter type peeling device has been used to peel off road markings such as white lines drawn on roads. This requires a lot of work time because it cannot be performed at a speed higher than a certain level because the rotating cutter cuts the road surface. In addition, the loud noises not only disturb the local residents and passersby, but also the dust that has been removed from the road markings, such as white lines on the road surface, is thrown up by the cutter blades and scattered as fine powder around. It was very annoying to roadside houses and passers-by. Also, it took time to remove and clean the scattered dust and dust. Furthermore, when trying to completely separate the boundary between the road markings such as the white line and the road surface, there was a defect that the road surface was cut too much. For this reason, it was necessary to pay attention to the work, and the workability was not good. In particular, pavement roads that are permeable to rainwater and are used on many roads, including highways, are soft and excessively cut, resulting in the formation of grooves on the road surface. On expressways, steps due to trenches are not allowed, so renovation work for embedding trenches was costly and time-consuming. In addition, in the case of a cutter-type peeling device, it is necessary to replace the wear of the blade of the cutter for cutting the road sign, which requires an operation cost.

As shown in FIG. 4, the separator 24 includes a cylindrical storage container 42, a cylindrical separation container 43 disposed in the storage container 42, and a hopper disposed below the separation container 43. 47.

A suction port 20 is formed in the upper part of the inner circular wall of the separation container 43 through which the suction hose 20 is inserted. The blowing port 46 opens toward the center on the plane of the separation container 43. The number of the blowing ports 46 may be plural. Further, an inner lid 53 is mounted on the upper surface of the separation container 43. Four first discharge ports 44 are formed in the inner lid 53. Further, a filtering member 36 is inserted inside the separation container 43. The filtering member 36 can open the outer lid 54 and the inner lid 53 on the upper surface of the storage container 42 and pull it out upward.

The filtering member 36 includes five filters 36 a, 36 b, 36 c, 36 d, 36 e made of a punched metal formed in a circular shape, and a holding member 52 penetrating through the center of the filters 36 a to 36 e.

(Compressor D) Compressor D is pressurized air for injecting colliders from the injection nozzle 12 and decompressed intake air for sucking colliders and white line and other dusts such as white lines from the recovery nozzle 14. Supply. For example, a DPS180SPD-2 type compressor can be used.

(Generator E) The generator E supplies electric power to the road surface working device A and the compressor D. For example, a YDG-S series generator can be used.

In the road marking peeling device of the present invention, the first storage tank 23 and the second storage tank 25 of the injection and recovery device B constitute storage means for storing the impactor, and the compressor D and the injection and recovery device B The colliding element supply hose 18 and the injection nozzle 12 of the road surface working device A constitute injection means for injecting the colliding element. The compressor D, the suction hose 20 of the injection and recovery device B, and the road surface working device A The collection nozzle 14, the dust collector, the first storage tank 23, and the second storage tank 25 constitute a collection unit that collects the collider and the dust marked on the road, such as a white line, and the collision by the separator 24. It constitutes a separating means for separating particles and dust.

The operation of this embodiment will be described below. The road surface working device A travels on the road surface such that the opening 110 of the working unit 1 contacts the road marking such as a white line, and the injection recovery device B, the dust collecting device C, the compressor D, and the generator E are connected to the road surface working device A. Work by loading on the truck to be run.

The compressor D is operated, and the collision element 13 is supplied from the first storage tank 23 of the injection device to the injection nozzle 12 of the working unit 1 via the collision element supply hose 18 so that the road surface, such as a white line, is cut off. Spray on sign. As a result, road markings such as white lines are peeled off. The dust and collider 13 on the road marking such as the peeled white line are collected through the collection nozzle 14. Dust on road markings such as the collider 13 and the white line is sent from the compressor D to the separator 24 through the suction hose 20 by applying reduced-pressure air through the suction hose 20.

Since the inside of the separator 24 is depressurized by the compressor D to be in a negative pressure state, the impactor 13 having a large specific gravity passes through the filter member 36 including a plurality of filters 36 a to 36 e in the separator 24 and a lower hopper. 47. On the other hand, dust on the road marking such as a white line having a small specific gravity is collected by the dust collector C via the delivery pipe 38 by the action of the compressor D.

First, the impactor and the separated dust are conveyed together with the compressed air through the suction hose 20 into the separation container 43. At the same time, since the pressure is reduced by the compressor D to be in a negative pressure state, the impactor and the dust are rapidly diffused at high speed to the inner wall surface of the separation container 43, the lower surface of the inner lid 53, and the upper surface of the uppermost filter 36a. At this time, the dust having a small specific gravity is blown out from the first discharge port 44 by the action of the compressor, passes through the space between the outer upper surface of the separation container 43 and the back surface of the outer lid 54 of the storage container 42, and passes through the delivery pipe 38. And collected by the dust collector C. Next, the collider and the dust not discharged from the first discharge port 44 fall onto the filter 36b and collide with the upper surface of the filter 36b to be separated. Here, the dust having a small specific gravity is sowed again, and is blown out from the first discharge port 44 through the punched hole of the filter 36a. Further, the impact element and the dust that have passed through the punched hole of the filter 36b and fallen onto the filter 36c are separated again as if they were separated on the filter 36b.

After such a process, finally, the collider and the dust that have passed through the filter 36 e fall below the hopper 47. From the outlet pipe 38 through the space between the outer wall surface of the separation container 43 and the inner wall surface of the storage container 42.

The collision element 13 housed in the hopper 47 of the separator 24 is housed in the second storage tank 25 by the switching valve 30. Here, when the first storage tank 23 is emptied, when the switching valve 32 switches to the second storage tank 25 and supplies the colliding element 13 to the injection nozzle 12, the colliding element 13 is not replenished. Work can be continued. When a plurality of second storage tanks 25 are provided, the collision elements 13 to be supplied to the injection nozzles 12 are switched and used, so that the supply of the collision elements to be injected can be continuously performed. Work can be performed more efficiently.

As shown in FIG. 6, the filtering member 36 of the separator 24 is formed in a circular shape and has circular filters 36a, 36b, 36c, 36d, 36e each having a plurality of through holes. And a holding member 52 penetrating the center of these filters.

In the separator 24, there are six stages of separation between the dust and the collider, so that the separation due to the difference in the specific gravity is completely performed, and the collision of the collected dust dust is performed. The child is also exfoliated.

[Effect of the invention]

 According to the present invention, the road markings are separated by the collider ejected from the injection nozzle, and the dust and the colliders by the road marking such as the separated white line are sucked from the collection nozzle and collected. Since there is almost no scattering and the waste is collected at the same time as the work, the surrounding houses and passers-by are not bothered, and the work of removing the scattered dust can be eliminated. Furthermore, the noise can be kept extremely low. In addition, since the jetted impactor is separated by the collision action, it is possible to prevent the road surface from being excessively ground, and it is possible to eliminate wasteful work such as refilling a groove on a road marking separated road surface such as a white line.

In addition, since the collider ejected for the separation is immediately collected at the site and reused, not only there is no consumable member but the cost can be reduced, but also the efficiency of the continuous operation can be improved.

Further, since the vehicle can travel along a road mark such as a white line where the user wants to peel off the set of devices, work efficiency can be improved.
