Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cover device for a road surface groove cutting wheel that cuts a road surface to form a groove having a predetermined depth.

[0002]

[Prior art]

 For example, in order to prevent slippage of the road surface due to freezing of water on the road surface, it is necessary to provide a drainage groove of a predetermined depth on the road surface such as an expressway in order to positively remove molten water or rainwater. Such a ditch has a relatively shallow depth that does not reduce the strength of concrete or asphalt roads, for example, a depth of approximately 5 cm, and corresponds to the ditch of the road surface after the road is completed. It is formed by deleting the part to be used.

Conventionally, two vertical cutting lines having an interval corresponding to the width of a groove to be formed on a road surface are formed by using a diamond cutter for the depth of the groove to be formed, and between the two vertical cutting lines. The chipping was carried out by hammering with a hammer, and after removing the chippings generated by it, the inside of the groove was washed and a waterproof coating was applied to the bottom to ensure the waterproofness of the bottom.

However, such conventional road surface groove forming work requires vertical cutting work, chipping work, chipping debris removing work, and waterproof paint applying work, which requires a long working period and increases the working cost. In addition, since the unevenness is formed at the bottom of the groove by the chipping work, the flow of water is not smooth, and there is a drawback that deposition due to catching dust is likely to occur.

Therefore, in the Japanese Patent Application No. 8-9539 (unpublished technology), the present applicant has a circumference having a width substantially the same as the cross-sectional shape of a groove to be formed on a road surface as shown in FIG. It is proposed to form a groove having a predetermined depth on the road surface by using a road groove cutting wheel in which a plurality of cutting teeth are projected at predetermined intervals in a predetermined direction at a predetermined height.

[0006] By doing so, the road surface made of concrete or asphalt is efficiently removed by cutting, so that the work period can be shortened and the groove forming work can be performed at a lower cost than before. In addition, since the bottom of such a groove is smoother than when performing a chipping operation, the flow of water is smooth and the trapping of dust, which causes dust accumulation, is preferably suppressed. Of.

[0007]

[Problems to be solved by the device]

 However, in the groove forming work using the road surface groove cutting wheel, a large amount of cutting fluid containing mud is generated during cutting, and such cutting fluid is called, for example, “Noro”. If the cutting fluid is left on the road surface and is left unattended, the road surface becomes dirty and it becomes slippery, which causes great inconvenience to pedestrians and vehicles. It was necessary to carry out cleaning work for the above, which resulted in extending the work period and increasing the work cost.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a cover device for a wheel for cutting a road surface groove, which can omit the cleaning work of the cutting fluid after the groove forming work. To provide.

[0009]

 In order to achieve the above object, the first aspect of the present invention is as follows: A road groove cutting wheel cover device for cutting, comprising: (b) a semicircular wheel cover that is fixed to the work vehicle and covers the road groove cutting wheel; and (c) the road surface groove. A through hole that receives the cutting wheel and an annular peripheral wall that is erected around the through hole and into which the wheel cover is fitted are provided. Sliding that slides on the road surface as the work vehicle moves. Member and (d) a first suction pipe provided on the rear side of the annular peripheral wall of the sliding member and for sucking the cutting fluid in the groove formed by cutting the road surface by the road surface groove cutting wheel. And (e) the slide member is installed on the rear side of the first suction pipe. Is characterized by having a blocking plate for blocking the flow to the rear of the cutting fluid in the road surface groove groove formed in the rear of the cutting wheel.

A second aspect of the present invention is the cover device for a road surface groove cutting wheel of the first aspect, wherein the blocking plate has substantially the same width as that of the groove, and a retaining hole formed in the sliding member is used to insert the groove into the groove. It is characterized by being dropped into.

According to a third aspect of the invention, in the road groove cutting wheel cover device of the first aspect, the first suction tube has a lower end portion located in the groove.

[0016]

[Effect of the invention]

 According to the first aspect of the present invention, when the work vehicle is advanced to perform the groove forming work on the road surface, the annular peripheral wall is rubbed against the wheel cover and the sliding member advances, so that the blocking plate causes the road surface groove to move. Prevents the rearward flow of cutting fluid in the groove formed behind the cutting wheel. On the other hand, since the sliding member is pressed against the road surface by its own weight, the lower surface of the sliding member is kept relatively airtight, and the cutting fluid in the groove is easily sucked from the first suction pipe. Therefore, a large amount of cutting fluid containing mud generated by cutting the road surface is removed at the same time as the groove forming work, so it is possible to omit the cutting fluid cleaning operation after the groove forming work. The period is shortened and the work cost is reduced.

According to the second invention, since the blocking plate is dropped through the holding hole, the blocking plate always slides in close contact with the bottom surface of the groove by its own weight, so that the cutting fluid flows backward. Are more preferably prevented.

According to the third invention, since the lower end of the first suction pipe is located in the groove, it is possible to efficiently suck the sediment such as crushed stone mixed with the cutting fluid in the groove. Can be done.

According to the fourth invention, the cutting fluid that could not be sucked by the first suction pipe is washed by being poured from the water injection portion, and the fluid that has been poured into the cleaned cutting fluid is sucked by the second suction pipe. Since it is sucked from the pipe, it is possible to more suitably remove the cutting fluid remaining in the groove, and the inside of the groove is further cleaned. In addition, since the water injection part is installed on the rear side of the second suction pipe, the water flow injected from the water injection part vigorously acts as a barrier and the fluid containing a relatively large amount of cutting fluid is almost sucked by the second suction pipe. As a result, it is difficult to flow into the groove behind the water injection part, so the inside of the groove is even cleaner.

According to the fifth aspect, on the road surface near the groove, the cutting fluid is sucked from the third suction pipe through the slit opening at the peripheral edge of the lower surface of the sliding member. It becomes possible to remove the cutting fluid more preferably.

[0021] According to the sixth aspect of the invention, the brush is planted on the peripheral portion of the lower surface of the sliding member, so that the airtightness between the sliding surface and the sliding member when the sliding member is pressed against the road surface by its own weight. Since it is further improved, the suction force from the peripheral portion of the sliding member is increased and the cutting fluid can be more preferably removed.

According to the seventh aspect of the invention, the brush is planted outside the slit at the peripheral portion of the lower surface of the sliding member, so that the sliding member slides on the road surface when it is pressed against the road surface by its own weight. Since the airtightness with the member is further improved, the suction force from the peripheral edge of the sliding member is increased without being greatly affected by the unevenness of the road surface, and the cutting fluid can be more preferably removed. .

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view for explaining the configuration of a self-propelled road surface groove cutting device 12 to which a cover device 11 for a road surface groove cutting wheel 10 of the present invention is applied.

In FIG. 1, the road surface groove cutting device 12 includes a box-shaped vehicle body 18 supported by a pair of driving wheels, that is, a rear wheel 14 and a pair of front wheels 16. The rear wheel 14 is operatively connected to an engine (not shown) provided in the vehicle body 18 through a transmission, and the front wheel 16 is operated by rotating the vertical handle 20. The vehicle body 18 is supported via a vertical mechanism (not shown).

The front portion of the vehicle body 18 is rotatably supported around a horizontal axis of rotation that is orthogonal to the forward direction of the vehicle body 18 and is rotationally driven through the engine and a transmission belt. A rotating shaft 22 is provided. A road surface groove cutting wheel 10 for cutting the road surface 26 of the road 24 to form a groove 28 is fixed to the shaft end of the rotary shaft 22. The vertical handle 20 is used to adjust the cutting depth of the road surface groove cutting wheel 10, that is, the depth of the groove 28 by changing the vertical position of the front wheel 16 with respect to the vehicle body 18 by its rotating operation.

An arm 34 having a pointer 30 and a roller 32 at its tip is provided on the front of the vehicle body 18 so as to be rotatable around a horizontal axis. When cutting the groove 28, when the vehicle body 18 moves forward, the arm 34 is tilted forward until the roller 32 at the tip thereof comes into contact with the road surface 26 to support the arm 34. Therefore, when the operator moves the vehicle body 18 forward in a direction in which the target line previously attached to the road surface 26 and the pointer 30 coincide with each other, the groove 28 is formed along the target line. ing. When the cover device 11 is attached to the road surface groove cutting device 12, it becomes as shown in FIG.

Next, the configuration of the cover device 11 shown in FIG. 2 will be described in detail. FIG. 3 is a left side view of the cover device 11, FIG. 4 is a right side view, FIG. 5 is a top view, and FIG. 6 is a bottom view. The cover device 11 includes a wheel cover 40 shown in FIG. 7 and a sliding member 42 shown in FIG.

3 to 8, a wheel cover 40 has a semi-circular shape that covers substantially the upper half of the road surface groove cutting wheel 10, and the rotary shaft 22 is provided in the center of the lower end side of the left side surface of the wheel cover 40. Is provided with a hole 43.

Further, on the left side surface of the wheel cover 40, a fixing portion 46 including a bracket 44 and a screw 45 is provided at a front center portion, and a hooking portion 49 including a longitudinal member 47 and a hooking member 48 is provided at a rear center portion. Are provided, and the wheel cover 40 is fixed to the vehicle body 18 by being fastened and locked to a fixing portion (not shown) and a latching portion, which are provided on the right side surface of the vehicle body 18, respectively. A cutting fluid injection unit 50 for injecting a cutting fluid such as water into the road surface groove cutting wheel 10 through a nozzle pipe (not shown) fixed in the wheel cover 40 is provided in the center of the upper surface of the wheel cover 40. Has been.

A rectangular through hole 52 for receiving the road surface groove cutting wheel 10 is provided in the front part of the sliding member 42, and the wheel cover 40 is provided upright around the through hole 52 so as to have a predetermined play. An annular peripheral wall 54 to be fitted therein is provided. The annular peripheral wall 54 is provided lower on the left side surface, that is, on the side of the vehicle body 18 than on the right side surface thereof so as not to overlap with the fixed portion 46. A vertical notch 68 is provided for penetrating the rotary shaft 22 and is made up of a pair of vertical cutting lines that are broadly cut vertically from the upper end to the lower end.

In the sliding member 42, a first suction pipe 56, a holding hole 58, a second suction pipe 60, a water injection section 62, and a third suction pipe 64 are sequentially erected on the rear side of the annular peripheral wall 54, Immediately in front of the peripheral wall 54, a fourth suction pipe 66 is provided with a slight inclination to the front. A vacuum hose extending from a vacuum device (not shown) provided in the road surface groove cutting device 12 is connected to the upper end of each suction pipe.

The holding hole 58 has a blocking plate 78 formed of a metal thick plate having substantially the same radius as the radius of the road surface groove cutting wheel 10 and a width dimension slightly smaller than that of the groove 28. It is a rectangular hole provided with a width and thickness slightly larger than the width and thickness of the blocking plate 78 so that it can be inserted. The water injection part 62 is a rectangular hole having a longitudinal direction parallel to the longitudinal direction of the sliding member 42.

As shown in FIG. 6, a pair of slits 80 are provided in the lower surface peripheral portion of the sliding member 42 adjacent to the long side of the through hole 52, and a slit is provided immediately behind the water injection portion 62. A V-shaped slit 82 is provided. As shown in FIG. 9, the sliding member 42 has a double structure in which a predetermined space is provided above the slits 80 and 82, and the cutting fluid sucked from the slits 80 and 82. Etc. are introduced into the third suction pipe 64 and the fourth suction pipe 66 through these spaces, respectively, and sucked and removed.

Further, the first suction pipe 56 and the second suction pipe 60 have a structure in which the lower end portions of the first suction pipe 56 and the second suction pipe 60 are slightly protruded in the lower surface direction from the sliding member 42 so that they are located in the groove 28 by about 3 cm. A brush 84 is provided on the peripheral portion of the lower surface of the sliding member 42 so as to be continuous with the outside of the slits 80 and 82 only at three sides including a pair of side edges and a rear edge in the longitudinal direction.

As described above, according to the present embodiment, as shown in FIG. 9, when the vehicle body 18 is advanced to perform the groove forming operation on the road surface 26, the groove is formed behind the road surface groove cutting wheel 10. 28 is formed, the sliding member 42 is moved forward by being rubbed by the wheel cover 40 fixed to the vehicle body 18, so that the blocking plate 78 forms the groove 28 formed in the rear of the road surface groove cutting wheel 10. It slides inside to prevent the cutting fluid from flowing backward. On the other hand, since the sliding member 42 is pressed against the road surface 26 by its own weight, the lower surface of the sliding member 42 is kept airtight, and the cutting fluid is easily sucked from the first suction pipe 56. Therefore, a large amount of cutting fluid containing mud generated by the cutting of the road surface 26 is sucked and removed at the same time as the groove forming work as shown by the arrow in FIG. 9, so the cleaning work of the cutting fluid after the groove forming work is performed. Can be omitted, the work period can be shortened, and the work cost can be reduced.

Further, according to this embodiment, since the blocking plate 78 is dropped through the holding hole 58, the blocking plate 78, which is a relatively heavy metal thick plate, is always grooved by its own weight. Since the sliding contact is made with the bottom surface of 28, the backward flow of the cutting fluid is more preferably prevented.

Further, according to the present embodiment, since the lower ends of the first suction pipe 56 and the second suction pipe 60 are located in the groove 28, crushed stones mixed with the cutting fluid from the groove 28 can be prevented. Precipitates can also be sucked efficiently.

Further, according to the present embodiment, since the water pouring portion 62 is provided, the cutting fluid that could not be sucked by the first suction pipe 56 is water-purged to be cleaned, and further into the groove 28. The remaining cutting fluid is sucked from the second suction pipe 60 together with the newly injected fluid as shown by the arrow in FIG. 9, so that the cutting fluid can be removed more preferably. Further, since the water injection part 62 is provided on the rear side of the second suction pipe 60, the water flow that is vigorously injected from the water injection part 62 serves as a barrier to prevent the fluid containing a relatively large amount of cutting fluid from flowing through the second suction pipe 60. Most of the air is sucked, and it is difficult for the water to flow into the groove behind the water injection part 62, so that the inside of the groove is further cleaned.

Further, according to the present embodiment, the cutting fluid is sucked from the third suction pipe 64 on the road surface near the groove 28 through the slit 82 opening to the peripheral portion of the lower surface of the sliding member 42. It becomes possible to more suitably remove the cutting fluid on the road surface near the groove 28.

Further, according to the present embodiment, the brush 84 is planted in the peripheral portion of the lower surface of the sliding member 42, so that the sliding member 42 slides on the road surface 26 when it is pressed against the road surface 26 by its own weight. Since the airtightness with the moving member 42 is further improved, the suction force from the peripheral portion of the sliding member 42 is increased, and the brush 84 is planted outside the slits 80 and 82, so that the The suction force from the peripheral portion of the sliding member 42 increases without being affected by the unevenness so much, and the cutting fluid can be removed more preferably.

Although one embodiment of the present invention has been described above in detail with reference to the drawings, the present invention can be modified in various other ways without departing from the spirit of the invention.
