Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for efficiently and completely removing unnecessary or changed road sign lines on a road surface.

Conventional methods for removing road sign lines, etc., involve removing them using a drum-type cutter that has a blade on the cylindrical surface of the drum. However, after the removal process is completed, the road surface has countless irregularities caused by the blade digging into it. At the same time, paint remains in spots and cannot be removed completely.After the removal process, the road surface to be removed is manually corrected, and in some cases, paint with a color similar to that of the asphalt is applied. I needed to finish it.

When removing road sign lines, etc. from the road surface, it is important to ensure that the removal does not damage the road surface and create bumps or rough surfaces, so that it does not become an obstacle to vehicle driving. An even more important issue is to completely and efficiently remove the paint.

In view of the above, an object of the present invention is to provide a device for deleting road sign lines, etc. on a road surface, which completely and efficiently deletes sign lines, etc., without creating steps, rough surfaces, etc. on the road surface after deletion. That is.

They mesh, and their rotation loci overlap at the center, and this cutting edge 14 is provided to be replaceable.

The main shaft 13 is rotatably supported by a main shaft cylinder 15, and this main shaft cylinder 15 is supported on the support body 2 so as to be movable up and down.Furthermore, a spline shaft 16 is provided at the upper end of the main shaft 13, and the main shaft cylinder 15 is rotatably supported. A vertical rack 17 is provided on one side. The rotating means 12 includes a prime mover 18 fixed to the upper part of the support 2.
The rotation of the drive pulley 19 fixed to the shaft end of the V-belt 20
The force is transmitted to the driven pulley 21, and the drive bevel gear 22, which is disposed on the lower end of the same shaft as the driven pulley 21, is meshed with a pair of driven helical gears 23, 23.

This driven bevel gear 23 is supported by the support body 2 by upper and lower bushes 24 and 25, both of which have the same number of teeth, and has a shaft hole 26 in the center of the lower part of the shaft hole 26. It is spline-coupled to the spline koji 16 at the upper end so as to be vertically slidable. The rotational force of the prime mover 18 is transmitted to the driving bevel gear 22, and through the driven bevel gears 23, 23, the pair of rotary cutting tools 10, 10 are caused to rotate synchronously in opposite directions at the same rotation speed. On the other hand, the moving means 1
1, a screw gear 27 that meshes with the rack 17 of the main shaft cylinder 15 is supported on the support 2, a worm 29 is meshed with a worm wheel 28 fixed to the same axis as the screw gear 27, and the worm 29 is rotated. Screw gear 27
to move the main shaft 13 up and down together with the main shaft cylinder 15,
The rotary cutting tool 10 is moved in the vertical direction, respectively.

As shown in FIG.
31 are connected to each other, and synchronous gears 32, 32 having the same number of teeth are fixed to both operating shafts 31, 31, and both gears 32, 31 are connected to each other.
A sliding gear 33 that meshes with 32 at the same time is provided on the motion operating shaft 34, and when the sliding gear 33 and the synchronous gear 32 are adjacent to each other, the rotating operation of the interlocking operating shaft 34 allows both rotary cutting tools 10, 1 to be rotated.
0 can be moved up and down by the same amount at the same time, and when they are not engaged, they can be moved up and down separately by rotating the independent operating shafts 31, 31.

Further, the pair of rotary cutting tools 10, 10' have different rotational directions, their axes are inclined, and they are provided obliquely inwardly from the bottom to the top.

Further, as described above, the rotary cutting tool 10 is swung together with the support 2 by the swinging means 4 about the pivot shaft 5 of the support 2 as shown in FIG.
0 is tilted forward at a slight angle 8 with respect to the road surface 35, and when the cutting blade 14 is replaced, etc., it is rotated to a horizontal position as shown by the chain line. The pivot shaft 5 of the support body 2 is provided forward of the axis ○ of the rotary cutting tool 10 and further offset forward of the front end green of the cutting blade 14, so that when the rotary cutting tool 10 swings rearward, it will not touch the road surface. This prevents the cutting blade 14 from biting into the 35. In addition, in FIG. 1, reference numeral 36 indicates cutting shoulders provided on both sides of the lower part of the support body 2 to prevent scattering. To explain the cutting state by the above-mentioned removing device 1, the height of the pair of rotary cutting tools 10, 10 is adjusted by the moving means 11 for vertical movement, and the front head inclination angle 8 with respect to the road surface 35 is adjusted.
is adjusted by the swinging means 4 of the support body 2 and rotated around the axis by the rotating means 12, the cutting blade 14 cuts the road surface 35 as well as the coating layer 37 such as the marking line.

As shown in FIG. 4, since the pair of rotary cutting tools 10 and 10 are tilted inwardly, the cut portion 38 of the road surface 35 is cut deeply along with the coating layer 37. , remove the sides so that they become shallower. Furthermore, since the rotary cutting tools 10, 10 are tilted forward, the fifth
As shown in the figure, a slightly arcuate surface appears in the deleted portion 38 of the road surface 35. As mentioned above, the reason why the rotary cutting tools 10 and 10 are moved inward from each other is to make the boundary between the road surface 36 and the removed portion 38 smooth so that no step is generated, and the slope of the removed surface is 1/100. ~ If it is about 1.5/100,
The deepest part of the deletion part 38 is about 1 to 1.5 feet deep and is close to the road surface 3.
It does not impair the function of 5.

Moreover, when the rotary cutting tools 10, 10 are tilted in the forward direction, the removal layer material is not bitten by the rear side of the cutting blade 14, and the cutting blade 1
In this case, the height of the arc generated by the removed surface is a minute value and does not impair the function of the road surface 35. Further, when the pair of rotary cutting tools 10, 10 are rotated and cut so that their rotation directions are opposite to each other, the removal resistances for cutting the road surface 35 are canceled out and balanced, and the running and work of the trolley 3 are stabilized. .

In the above example, the rotational force of the prime mover 18 is transferred to the V-belt 2.
Transmission from 0' has the effect of absorbing vibrations during the removal operation, but other chain transmission or direct gear transmission mechanisms may also be used.

Further, the structure in which the rotary cutting tools 10, 10 are inclined inwardly using a pair of driven bevel gears 23, 23 can be changed to both rotary cutting tools 10, 10 by meshing with spur gears or other gears.
It is also possible to have a structure in which they are provided parallel to each other and perpendicular to each other. Furthermore,
In the moving means 11 shown in FIG.
The universal joint 30 can be made unnecessary by adopting a meshing structure in which the gears are bevel gears. FIG. 6 shows the removing device IA mounted on a power vehicle 39 so as to be suitable for large-scale work.
0 is equipped with a prime mover 41 that mainly provides driving power,
The output shaft 42 drives the wheels 43 forward or backward.

The pivot shaft 5 of the support body 2 is swingably supported in the center of the truck 40, and is connected to the prime mover 41 by a drive shaft 44 to drive the rotary cutting tool 10 in rotation. Reference numeral 45 denotes an operating handle for the swinging means 4, and 46 indicates an operating handle for the vertically moving means 11, which are provided on a hand bar 47.

48 is a hood for collecting removed waste, 49 is a dust collector, 50 is a seat, 51 is a mirror, and the hand bar 47 is attached to a motor vehicle 3.
In addition to the control lever 52 of 9, various operating devices are attached.

When this hand bar 47 is fixed in front of the seat 5, the operator can sit on the seat 5 and carry out the work while observing the cutting state of the rotary cutting tool 10 through the mirror 51 in the same way as when walking. I can do it. In addition, when deleting,
As shown in FIG. 8, a pair of rotary cutting tools 10, 10 are rotated inwardly in synchronization, and the cutting blade 14 is used to cut the coating layer 3 such as a marker line.
7 are sequentially removed together with the removed portion 38 of the road surface 35, and the removed calendar material is sucked and stored in the dust collector 49 from the hood 48. Fig. 7 shows the removal device IB mounted on a hand truck 53 to be suitable for small-scale work. A support body 2 equipped with a cutting tool 10 is swingably supported,
It is equipped with a hood 48, a dust collector 49, and an operation handle 46 for vertical movement, and runs on wheels 54.

Therefore, according to the device of the present invention as described above, a pair of rotary cutting tools are provided on a support body that is swingably supported in the traveling direction of the traveling carriage and are movable up and down, and the rotary cutting tools are rotated in different directions. and the mari-shins are inclined inward to each other,
The cutting blade at the tip of this rotary cutting tool removes marking lines, etc. and thinly removes the surface skin of the road surface, making it possible to completely remove the paint layer that is stubbornly adhered to the road surface with good work planning. Furthermore, the road surface after deletion is smooth without any bumps or rough surfaces, does not interfere with vehicle driving, effectively maintains the function of the road surface, and does not require post-processing. This allows road sign lines, etc. to be deleted efficiently and neatly.

Furthermore, since the rotary cutting tool can be placed in the forward direction of the traveling carriage, the life of the cutting blade can be extended without biting the cutting blade on the rear side of the cutting blade.
