Description

  The present invention relates to a road surface restoration apparatus that forms a groove having a predetermined depth by excavating and adjusting a surface of a crushed stone in which a pipe or the like is embedded, and leveling a pavement material at a predetermined height in the groove.

For example, after burying pipes such as gas pipes, water pipes, sewage pipes, telephone lines, etc. in the groove formed on the road, sand, earth and sand, crushed stones are put in the groove, and the pipe body is backfilled, The road surface is restored by laying paving materials such as asphalt.
FIG. 15 is a schematic diagram for explaining the procedure of the road surface restoration work as described above, and is a front view in which a road is cut in a direction perpendicular to the groove. First, as shown in FIG. 15 (a), the ground surface (road) 1 is excavated and trimmed to form a groove 1a, and the pipe body 2 is disposed at the bottom of the groove 1a. Thereafter, as shown in FIG. 15 (b), the crushed stone 3 is put into the groove 1 a to embed the tube body 2. As shown in FIG. 15 (c), after rolling the crushed stone 3, as shown in FIG. 15 (d), the surface of the crushed stone 3 is excavated and trimmed to form a groove 3a having a predetermined depth.

And as shown in FIG.15 (e), the asphalt 4 which is a paving material is thrown into this groove | channel 3a, and the asphalt 4 is leveled in cross-sectional trapezoid shape with the height ensured previously from the ground surface. Finally, using a roller or the like, rolling is performed until the surface of the asphalt 4 becomes the same height as the ground surface 1 as shown in FIG.
Of the above steps, the groove 3a in (d) is mainly performed using a work machine such as a power shovel. However, it takes time and skill to determine the position and depth, and the asphalt 4 in (e) is leveled. Currently, this is done manually using a scoop or rake.

However, the above-mentioned conventional road restoration work is not easy even for a skilled person to finish the thickness and flatness to a high degree, and it takes time and labor, and there are cost problems, and there is a lot of waste on resources, and the finish is finished. If the road surface is excessively uneven, there is a problem in that it causes discomfort during driving. Furthermore, there is a problem in that logistics is adversely affected if the traffic regulation due to work takes a long time.
By the way, Patent Document 1 proposes a work machine such as a power excavator that enables excavation and leveling of a groove by using a drainage plate that is narrower than between the crawler belts.

  The technique described in this document can greatly reduce the work load and work time for trench excavation / correction, and is a prominent proposal. However, only a fixed-width groove corresponding to the earth excavator can be excavated and trimmed, and the earth excavator provided on the excavator etc. is used as it is, so the road surface with unevenness that cannot be followed by an excavator etc. However, there is a problem that the depth of the excavated and trimmed groove may be uneven. In addition, the work machine described in the above document has the disadvantage that it can only perform trench excavation and leveling, and asphalt leveling has to be relied on manually.

The paving unit finisher described in Patent Document 2 is capable of entering a small and narrow area and performing fine paving work. According to this working machine, the leveling work of asphalt is automated. be able to.
However, the dedicated work machine described in this document is large and expensive, and there is a problem that the cost increases when used for a small-scale road restoration work.

  The road surface leveling device for construction described in Patent Document 3 has a leveling plate for groove cutting, a blade for leveling asphalt, and a chamfer for chamfering both sides of the asphalt. Asphalt and other paving materials can be leveled with separate devices, but as with Patent Document 1, the excavator provided on a power shovel or the like can be used as it is, or it can be pulled by a dump truck or the like. Therefore, the problem that the depth of the excavated and leveled groove and the leveling surface of the asphalt may become uneven on an uneven road surface that cannot be followed by a power shovel or a dump truck cannot be solved.

Moreover, in the techniques described in these documents, there is a problem that the smoothness of the surface of the restoration road surface is low and the quality is low because the rolling is performed as it is after leveling the pavement material. Such a problem can be solved by heating and pressing the surface of the pavement after leveling and rolling, but there is a problem that the number of processes increases and the cost increases.

Preferred embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view illustrating a schematic configuration according to an embodiment of a road surface restoration device of the present invention, and FIG. 2 (a) is a diagram in which a top plate of a scraping plate is shifted laterally with respect to a back plate. FIG. 2B is a partially enlarged plan view of a main part for explaining the state when the front plate is shifted laterally with respect to the back plate.

  As shown in FIG. 1, the road surface restoration device 10 is provided with a damper function on an arm of a working machine such as a power shovel that is a traveling body, an arm that is lifted and lowered by a hydraulic cylinder or an air cylinder, and the like. Can be provided. The damper function prevents the arm from rotating or moving against the load generated during excavation and leveling, and if the road surface is uneven, follow the unevenness to the traveling body. The arm is rotated or moved. The damper function can be obtained by adjusting the pressure of the fluid supplied to the hydraulic cylinder or the air cylinder, or by interposing an elastic body such as rubber or a spring between the road surface restoration device 10 and the arm. Obtainable.

  The road surface restoration device 10 is disposed on both sides of the board 10a attached to the tip of the arm, the scraper board 11 attached to the board 10a so that the height position can be adjusted, and the board 10a. A pair of side plates 12 and 12 and a molding member 14 for leveling the side surface of asphalt that is detachably attached to the opposing surfaces of the side plates 12 and 12 with bolts 14a or the like (the other side plate 12 is shown in the figure) And sled skids 13 and 13 that are attached to the lower ends of the side plates 12 and 12 and are in contact with the ground surface 1.

  The scraper plate 11 of this embodiment has a structure in which two flat plates are overlapped, and a back plate 112 fixed with bolts or the like to the substrate 10a and a surface of the back plate 112 are overlapped. A front plate 111 and an L-shaped slide guide 113 attached to the upper end of the front plate 111 are provided. Then, the L-shaped slide guide 113 is engaged with the upper end edge of the back plate 112 and the front plate 111 is suspended from the back plate 112 by the slide guide 113, and the bolt 111b (see FIG. 2B) or the like. The front plate 111 is fixed to the back plate 112 or the substrate 10a. As shown in FIG. 2 (a), the scraper plate 11 having such a configuration slides the front plate 111 and the back plate 112 relatively in the horizontal direction, so that the width of the groove 3a to be excavated / rectified is shown. There is an advantage that the width of the scraper board 11 can be easily changed according to the change of

  For example, as shown in FIG. 2B, all or part of the edge 111 a of the front plate 111 is bent toward the back plate 112, and the bent edge 111 a of the front plate 111 is brought into contact with the back plate 112. Thus, it is possible to suppress the deformation of the front plate 111 when the groove 3a is excavated and trimmed in a state where the width of the scraper plate 11 is widened. In addition, as shown in FIG. 2, by forming the width in the longitudinal direction of the slide guide 113 to be equal to or greater than the maximum width between the side plates 12 and 12, or the maximum width of the scraping plate 11 after the width change, By using this slide guide 113, it is possible to prevent spilling of crushed stone and asphalt to the rear.

  Further, the scraper plate 11 can be adjusted in height with respect to the substrate 10a by a combination of a height adjusting bolt 11a and a fixing bolt 11b as shown in FIG. 6, for example. In the example shown in FIG. 6, the bracket 11c is formed in the vicinity of the upper end of the scraper plate 11 so as to face the upper end surface of the inverted L-shaped substrate 10a, and the spiral hole of the bracket 11c formed by welding a nut or the like. The height adjusting bolt 11a is screwed into the screw. Then, after adjusting the height of the scraping plate 11 with the height adjusting bolt 11a, a nut is fastened to a fixing bolt 11b such as an anchor bolt standing on the upper end surface of the substrate 10a, and the scraping plate with respect to the substrate 10a is tightened. 11 height positions are determined.

  As shown in FIGS. 1 and 2A, the side plates 12 and 12 of this embodiment have flange portions 12a that project in the width direction of the substrate 10a. A hole 12b through which a bolt 12c for attaching the side plates 12, 12 to the substrate 10a is inserted is formed through the flange portion 12a. On the other hand, a hole 10b through which the bolt 12c is inserted is formed through the substrate 10a, and the side plates 12 and 12 are fixed to the substrate 10a by tightening a nut to the hole 12b and the bolt 12c inserted through the hole 10b.

Of the two side plates 12 and 12, at least the side plate 12 that interferes when the front plate 111 is slid with respect to the back plate 112 can change the mounting position on the substrate 10 a by the same amount as the sliding amount of the front plate 111. Like that.
In this embodiment, the space between the side plates 12 and 12 is changed by forming the hole 10b of the substrate 10a as a long hole having a long axis in the left-right direction and changing the insertion position of the bolt 12c in the hole 10b. I can do it.
Further, the holes 12b and 12b formed in the flange portions 12a and 12a of the two side plates 12 and 12 are arranged so that the height positions of the side plates 12 and 12 can be adjusted according to wear of the skids 13 and 13 described later. It is preferable to form a long hole having a long axis in the direction.

The skids 13, 13 attached to the lower ends of the side plates 12, 12 may be of any material and shape as long as they are slippery with respect to the ground surface 1 and do not easily wear.
In addition to resin and metal, it can be formed of rubber. The rear ends of the skids 13 and 13 protrude slightly rearward from the scraper plate 11. The boundary between the skids 13 and 13 and the scraping board 11 applies a pressing force to the scraping board 11 with the excavator etc. of the excavator when excavating and adjusting the groove 3a or leveling the asphalt. It is formed as a pressing point 21a to be applied.

The thickness of the skids 13 and 13 is preferably larger than the level of the asphalt from the ground surface. Of the level of the asphalt that may be leveled using the road surface restoration device 10 of this embodiment, It is preferable to make it slightly larger than the maximum value.
The molded member 14 has inclined surfaces 14b for forming tapered surfaces on both sides of the asphalt when leveling the asphalt. The lower end edge of the inclined surface 14b is positioned at the lower ends of the skids 13 and 13. Is preferred. Therefore, the hole 12d of the side plate 12 through which the mounting bolt 14a is inserted has a long axis in the vertical direction so that the height position of the molding member 14 in the side plate 12, 12 can be adjusted according to wear of the skids 13, 13 and the like. It is good to form as a long hole which has.

  When excavating and adjusting the groove 3a using the scraper plate 11, the lower end of the scraper plate 11 is less than the skids 13 and 13 by the dimension corresponding to the depth of the groove 3a to be excavated and adjusted. Is also positioned below. For example, when the depth of the groove 3a after excavation and leveling is set to 50 mm from the ground surface, the lower end of the scraping plate 11 is 50 mm-α (α is the level of rotation at the time of leveling). It is positioned below by the dimension) considering the settlement due to pressure.

  In addition, when leveling the asphalt 4 using the scraping board 11, the lower end of the scraping board 11 is positioned above the skids 13 and 13 by a dimension corresponding to the leveling height of the asphalt. For example, when the leveling height of the asphalt is 50 mm from the excavation and leveling front of the groove 3a, the lower end of the scraping plate 11 is 50 mm + β from the lower end of the skids 13 and 13 (β is a dimension taking into account pre-scaling). Position it above.

FIG. 3 is an overall view in which the road surface restoration device 10 having the above-described configuration is attached to a soil discharge plate 21 of a power shovel 20 that is a traveling body.

The substrate 10a may be fixed to the earth discharge plate 21 by welding, but it is preferable that the substrate 10a is detachably attached with a bolt or the like in consideration of using the power shovel 20 for other purposes. In this case, the lower edge of the earth discharging plate 21 is positioned at the pressing point 21a. When excavating and adjusting the groove 3a using the scraper plate 11 and leveling the asphalt, the scraper plate 11 and the skid 13 that are in contact with the pressing point 21a are always pressed down. Therefore, even if the surface of the ground surface 1 cannot be followed by the excavator 20, the arm 22 swings following the surface and the groove 3a having a constant depth is formed over the entire length of the recovery section. Asphalt can be leveled to a certain height according to the unevenness of the ground surface.

This will be described with reference to FIGS. 4 (a) and 4 (b). The example of FIG. 4 is a case where the groove 3a is excavated and leveled, but the same applies to asphalt leveling, and illustration and detailed description are omitted for leveling the asphalt.
As shown in FIGS. 4 (a) and 4 (b), even if the ground surface 1 is uneven, a pressing force is always applied to the scraping board 11 through the pressing point 21a. While the arm 22 is swung through the plate 21, the scraper plate 11 moves up and down following the unevenness of the ground surface 1, and the depth of the groove 3a can be kept constant.

On the other surface of the L-shaped bracket 121, a long hole 121a having a long axis in the left-right direction is formed, and a bolt 122 is inserted into the long hole 121a. The bolt 122 is screwed into a spiral hole formed in the front plate 111.
In this way, the side plate 121 and the bracket 121 are fixed to the front plate 111 with the bolts 122. Although not particularly shown, the same applies to the back plate 112 side.

By doing in this way, even if the height positions of the front plate 111 and the back plate 112 are changed, it can be coped with by changing the positions of the bolts 122 inserted through the long holes 12e. Moreover, even if the overlapping angle of the front plate 111 and the back plate 112 is changed, the bolt 122 inserted into the long hole 121a (and the long hole 12e if necessary) (and the long hole 12e as necessary) is inserted. This can be dealt with by changing the position of the bolt 122).
According to the road surface restoration device of this embodiment, for example, a leveling surface of the asphalt 4 as shown in FIGS. 8 (c) (i) (ii) can be obtained.

In the example of (i), the leveling surface of the asphalt 4 is formed in a mountain shape according to the inclination of the ground surfaces 1 and 1 inclined in a bent shape in the shape of a downward “ku”. In the example of (ii), the leveling surface of the asphalt 4 is bent halfway according to the height of the ground surfaces 1 and 1 having a step. In any case of FIGS. 8C, 8I, and ii, the dotted line in the figure indicates the asphalt surface after rolling.
In the road surface restoration device of the present invention, the board 10a, the earth discharging board 21, the front board 111, and the back board 112 are positioned higher than the ground surface 1 by the skid 13, so that FIG. 8 (c) (i) ( When the road surface restoration work as shown in ii) is performed, the ends of the substrate 10a (including the earth discharging plate 21), the front plate 111, and the back plate 112 can be prevented from coming into contact with the ground surface 1.
Thus, according to this embodiment, it becomes possible to apply the road surface restoration apparatus of the present invention to road surface restoration work according to various shapes of the ground surface 1.

  As shown in FIG. 9, the height adjustment mechanism 16 includes a jack 165 disposed substantially at the center of the substrate 10 a to raise and lower the front plate 111 and the back plate 112, and the front plate 111 and the back plate together with the jack 165. And a bolt 161 for supporting each of 112. The front plate 111 and the back plate 112 are respectively formed with through holes 111c and 112c. Bolts 161 are inserted through the long holes 111c and 112c, and a pair of nuts are formed from above and below the long holes 111c and 112c. The front plate 111 and the back plate 112 are fixed to the bolt 161 by fastening 162 and 162.

Between the jack 165 and the flange of the back plate 112, between the flange of the front plate 111 and the flange of the back plate 112, and between the nuts 162 and 162, contact the front plate 111 and the back plate 112 in a point contact state. A spherical or cylindrical rotating support 164 is disposed.
An example of a specific configuration of the rotating support 10 is shown in FIG.
In FIG. 10A, through holes 164b and 164d are formed at the center of a spherical body 164a (the one of (i)) or a cylindrical body 164c (the one of (ii)). Is inserted. This type of rotating support 10 has the advantage that it has a simple configuration and can be manufactured at low cost. In addition, when using the spherical body 164a or the cylindrical body 164c of FIG. 10A as the rotation support body 10, it is preferable to provide a washer 162a as shown in FIGS. 9B and 9C.

  Although the configuration of the spherical body 164a or the cylindrical body 164c in FIG. 10A is simple, the bolt 161 is inserted through the through holes 164b and 164d, so that it is not an ideal point contact state or line contact state. hard. Therefore, in the example shown in FIG. 10 (b), the ball 166b (of (i)) or the roller 166c ((ii)) is formed on one surface of the support plate 166 formed with a through hole 166a through which the bolt 161 is inserted. Is supported by the supports 166d and 166e in a rotatable manner.

  The rotating support 164 as described above is a single point in the case of a spherical shape, and a line in the case of a cylindrical shape, and is in contact with the front plate 111 and the back plate 112. Even if the angle changes, the front plate 111 and the back plate 112 can be supported by changing the contact position freely. When the overlapping angle of the front plate 111 and the back plate 112 is changed, the overlapping portion of the front plate 111 and the back plate 112 is moved up and down by the jack 165. In this case, if necessary, only the upper nut 162 is lightly loosened.

  As shown in (c), the spherical support 164 may be disposed between the upper and lower nuts 162. In this way, the overlapping angle of the front plate 111 and the back plate 112 can be changed only by raising and lowering the jack 165 without loosening the nut 162.

Next, a third embodiment of the present invention will be described with reference to FIG.
FIG. 11A is an overall perspective view of the road surface restoration device according to the third embodiment of the present invention, and FIG. 11B is an enlarged front view of a second introduction plate attached to the molded member.
In this embodiment, as shown in FIG. 11 (a), earth and sand, crushed stone, asphalt, and the like spilled on the ground surface 1 are placed on the tips of the skids 13, 13, and crushed stone excavation and leveling work and asphalt leveling are performed. However, the first introduction plates 180 and 180 to be taken in between the side plates 12 and 12 while performing the work are attached with bolts 181 a via the attachment members 181.

  The first introduction plates 180 and 180 may be formed of a rigid body such as metal, but may be formed of an elastic body such as rubber or resin. Moreover, the main body part attached to the front-end | tip of the skids 13 and 13 may be formed with a metal, and the part which touches the ground surface 1 may be formed with elastic bodies, such as rubber | gum and resin. Further, the pressing force of the first introduction plates 180 and 180 against the ground surface 1 is adjusted by interposing an elastic body such as a spring, rubber or resin block between the head of the bolt 181a and the mounting member 181. Is possible. The first introduction plates 180 and 180 need only be able to take in asphalt or the like between the side plates 12 and 12, and are not limited to the tips of the skids 13 and 13, but may be attached to the tips of the side plates 12 and 12, for example. .

Moreover, as shown to Fig.11 (a), it is good for the 1st introduction plates 180 and 180 to be attached so that the attachment angle can be changed with respect to the side plates 12 and 12. FIG. And when taking in earth and sand, crushed stone, asphalt, etc. on the ground surface 1 between the side plates 12, 12, the first introduction plates 180, 180 are pointed inward as shown by the solid line in FIG. When removing earth and sand, crushed stone, asphalt or the like outside the side plates 12 and 12, they are directed outward as indicated by the phantom lines.
According to this embodiment, since the foreign matter is removed from the ground surface 1 on which the skids 13 and 13 are moved by the first introduction plates 180 and 180, the foreign matter is placed on the leveling surface of the asphalt 4 and the bottom surface of the groove 3a. As a result, the surface of the road can be restored with higher quality.

  Furthermore, in this embodiment, as shown in FIGS. 11 (a) and 11 (b), asphalt 4 taken between the side plates 12 and 12 is inserted into the molding members 14 and 14 attached to the side plates 12 and 12, respectively. Second introduction plates 17 and 17 that are guided toward the inclined surface 14b of the molding members 14 and 14 are attached (in FIG. 11B, the direction in which the asphalt 4 is taken is indicated by an arrow I). The second introduction plates 17 and 17 can be formed by bending a part of a plate-like member such as a steel plate. The second introduction plates 17 and 17 are not limited to the molding members 14 and 14 as long as the asphalt 4 can be guided toward the inclined surfaces 14 b and 14 b of the molding members 14 and 14, for example, the side plates 12 and 12. You may attach to.

  The attachment positions of the second introduction plates 17 and 17 with respect to the molding members 14 and 14 may be any of the front end side, the midway portion, and the rear end side. However, the asphalt 4 is formed by the molding members 14 and 14 immediately before leveling. It is preferable to be taken into the inclined surfaces 14b and 14b and molded at a high density. The mounting position of the second introduction plates 17 and 17 is preferably behind the intermediate portion of the molded members 14 and 14 and more preferably provided on the rear end side as much as possible.

Next, an embodiment of a heating iron that is provided immediately after the scraping board 11 and smoothes the surface of the asphalt 4 leveled by the scraping board 11 will be described with reference to FIG.
FIG. 12 is related to one embodiment of a heating iron provided in the road surface restoration device of the present invention, (a) is a perspective view for explaining the entire configuration, (b) is a diagram for explaining the action of the heating iron.

The heating iron 30 is generally composed of a iron body 310 that heats and smoothly finishes the surface of the asphalt 4 and an attachment portion 320 that attaches the iron body 310 to a frame or an arm of the traveling body so that the height position can be adjusted. .
The iron body 310 is formed in a partial arc shape when viewed from the side, and moves with the traveling body while the partial arc-shaped surface is pressed against the asphalt. For heating the iron body 310, a burner, an electric heater, ignited charcoal, or the like can be used.
In the heating iron 30 of this embodiment, the iron body 310 is divided into two left and right divided bodies 311 and 312, and the divided bodies 311 and 312 are connected by a connecting metal fitting 313 whose connection angle can be adjusted. .

FIG. 12B is a partially enlarged view for explaining an example of the connection fitting 313. Of course, as long as the connection angle of the divided bodies 311 and 312 can be adjusted, the configuration of the connection fitting is not limited to that described below.
L-shaped connection fittings 313 are arranged back to back at corresponding positions of the divided bodies 311 and 312 and are fixed by welding or the like. An angle adjusting wedge 314 for adjusting the angle of the divided bodies 311 and 312 is inserted between the divided bodies 311 and 312. The angles of the divided bodies 311 and 312 are made to coincide with the inclination angle of the leveling surface of the asphalt 4 as shown in FIG. After the angle adjusting wedge 314 is inserted, the nuts 316 are screwed into one end of the bolts 315 through which the connecting fittings 313 and 313 and the angle adjusting wedge 314 are inserted and tightened, so that the divided bodies 311 and 312 are attached to the angle adjusting wedge 314. An angle corresponding to the taper angle, that is, an angle that matches the inclination angle of the leveling surface of the asphalt 4 is set.

  The attachment portion 320 includes a base 321 attached to the iron body 310, a helical shaft 322 that is rotatably supported at the tip of the base 321 and that does not move forward and backward in the axial direction, and the helical shaft 322. A nut 323 that is screwed together, a bracket 324 that attaches the nut 323 to the frame or arm of the traveling body, and a cylindrical guide 325 that is attached to the base 321 and guides the relative up and down movement of the nut 323. ing.

The upper end of the spiral shaft 322 is bent in a substantially horizontal direction, and a handle 322a for manually rotating the spiral shaft 322 is formed.
A groove 325a through which a bracket 324 integrally attached to the nut 323 is inserted is formed on the side surface of the guide 325 from the upper end to the lower end.
The guide 325 and the base 321 may be firmly fixed by welding, bolting, or the like, but may be attached so that the guide 325 can swing to some extent with respect to the base 321. For example, as shown in the figure, a pin 321a erected on the base 321 is inserted into a through hole of a flange 325b formed at the lower end of the guide 325, and a retaining pin 321b is engaged with a pin 321a protruding from the flange 325b. May be.
When the handle 322a is rotated with the heating iron 30 attached to the frame or arm of the traveling body via the bracket 324, the iron body 310 is moved up and down by the action of the spiral shaft 322 and the nut 323.

The pressing point for pressing the iron body 310 against the leveling surface of the asphalt 4 is determined by the attachment position of the attachment portion 320 with respect to the iron body 310. The iron body 310 is preferably pressed against the leveling surface of the asphalt 4 at an optimal pressing point.
Therefore, in the heating iron 30 of this embodiment, the attachment part 320 is attached to the iron body 310 so that the position can be adjusted in the width direction. For example, as shown in the illustrated example, the base 321 of the attachment portion 320 is attached to the upper edge portion of the divided body 311 with a bolt 326, and the bolt 326 is extended along the elongated hole 311a formed in the upper edge portion. The tightening position can be adjusted.
By doing in this way, even if the width of the leveling surface of the asphalt 4 changes as shown in FIG. 13A to FIG. 13B, for example, the pressing point P is set to the optimum position according to this change. Can be moved to.

  Further, when the leveling surface of the asphalt 4 has the horizontal surface 4a and the inclined surface 4b, the position of the boundary between the horizontal surface 4a and the inclined surface 4b (inclination angle change position T) is, for example, from the position of FIG. When it changes to the position of FIG.13 (c), it is necessary to change the position of the press point P while changing the position of the boundary part of the division bodies 311 and 312 according to this change. Therefore, in this embodiment, the fixing position of the bracket 324 with respect to the traveling body or the like can be adjusted in the width direction. Thereby, the position adjustment of the width direction of the heating iron 30 and the position adjustment of the press point P are attained.

FIG. 14 is a diagram for explaining the operation of the heating iron 30 having the above configuration.
FIG. 14A shows the time of excavation / correction of the groove 3a. At the time of excavation and leveling of the groove 3a, the heating iron 30 stands by behind the earth discharging plate 21. At this time, the iron body 310 of the heating iron 30 is preliminarily positioned at a position slightly higher than the ground surface 1 and lower than the height position of the lower edge of the scraper plate 11 when leveling the asphalt 4. .

FIG. 14B shows the leveling time of the asphalt 4. The asphalt 4 is leveled by the scraper board 11. The height position of the iron body 310 is set in advance to the height position where the finished asphalt 4 is smoothed by heating and pressing the smoothed asphalt 4, so that the surface of the smoothed asphalt 4 is immediately The surface is finished smooth by the heating iron 30.
That is, according to the heating iron 30 of the present invention, the leveling of the asphalt 4 and the smoothing by the heating iron 30 are performed simultaneously. Therefore, a dedicated process for finishing the surface of the asphalt 4 smoothly becomes unnecessary, and a high quality restoration road surface can be obtained at low cost.
When the heating iron 30 is pushed forward against the asphalt 4, the asphalt bulge is likely to be generated in front of the heating iron 30, but the heating iron 30 is made swingable like the heating iron 30 of the present invention. Thus, the occurrence of such a bulge can be suppressed.
When it is necessary to temporarily stop the leveling operation for some reason during the leveling of the asphalt 4, the heating iron 30 is heated in order to prevent excessive heating of the asphalt 4 by the heating iron 30. The heat source may be shut off or the handle 322a may be operated to raise the heating iron 30 and be separated from the asphalt 4.

Although the embodiment of the present invention has been described, the present invention is not limited to the above description.
For example, in the above description, a power shovel is taken as an example of the traveling body, but the road surface restoration device 10 can be moved to excavate and adjust the groove 3a and level the asphalt such as the asphalt 4. If there is, another traveling body such as a dump truck can be used. Moreover, it is possible not only to attach to the front part of the traveling body as described above, but also to work while pulling by attaching a road surface restoration device to the rear part of the traveling body.

Further, in the above description, the warp-shaped skids 13 and 13 as the guide member are described as an example, but the guide member can be shaped like a warp as long as it can follow the unevenness of the ground surface. Not only the skids 13 and 13 but other things, such as a roller shape, can be used. Furthermore, in the above description, the guide member is attached to the lower ends of the side plates 12 and 12, but it is also possible to attach the guide member to the substrate 10a, the earth discharging plate 21, the arm 22, and the like.
In the above description, the scraper plate 11 is described as having a structure in which two flat plates are overlapped. However, the scraper plate 11 may be composed of a single flat plate. When changing the groove width for excavation, the flat plate may be replaced with one corresponding to the groove width.

  Further, in the second embodiment, it has been described that the raising and lowering of the scraping board 11 is performed using the jack 165. However, since the scraping board 11 can be raised and lowered and positioned at a preset height position. If there is, it is possible to use not only the jack 16 but also a cylinder, a ball screw / nut mechanism or the like.

  In the third embodiment, both the first introduction plate and the second introduction plate are provided, but either one may be provided. Furthermore, although the third embodiment is based on the road surface restoration device of the first embodiment, it may be based on the road surface restoration device of the second embodiment.

  Furthermore, the heating iron 30 that smoothes the surface of the asphalt 4 is not limited to the above-described aspect, and may be various other aspects. For example, if only the surface of a flat pavement material without an inclination angle is to be finished, the heating iron 30 does not need to be divided into left and right parts, and the connection angle need not be adjustable. Further, if the surface of the paving material is always finished at a constant height, a height adjusting mechanism is not particularly required. If the problem of the pavement bulge does not occur in front of the iron body 310, the iron body 310 does not need to be swingable with respect to the arm or the traveling body.

Further, in the above description, the iron body 310 of the heating iron 30 is described as being divided into two parts, but may be divided into three parts or more.
Further, when the iron body 310 is divided into two or more like the heating iron 30 described in the above embodiment, the attachment portions 320 are provided in each of the divided bodies (the divided bodies 311 and 312 in the above embodiment). May be. By doing in this way, there exists an advantage that the press point P can be positioned in the optimal position in each of the division body (311 and 312). Furthermore, in this case, since the angles of the divided shapes 311 and 312 are determined by the mounting portions 320, it is not particularly necessary to adjust the connecting angle by the angle adjusting wedge 314 or the like as described above.

  The present invention can be widely applied to road surface restoration work after construction of gas pipes, water pipes, sewer pipes, telephone lines and the like. Moreover, the heating iron of this invention is applicable not only to the road surface restoration apparatus of this invention but other road surface restoration apparatuses.
