Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paving machine used for mechanized construction of thin-layer pavement using a resin-based color paving material (hereinafter sometimes simply referred to as paving material).

[0002]

2. Description of the Related Art Resin-based color pavement materials used as color pavement materials for aesthetically paving road surfaces such as park sidewalks and facility approaches are generally resins and aggregates (natural stones, artificial stones) as binders. , Rubber chips, etc.) and additives, and the pavement work has a pavement thickness of about 7 mm.
It is a very thin layer of about 35 mm. Moreover, since the binder (resin-based binder) used as an additive has a strong adhesive property, at present, the paving work is performed mainly by manual construction. As a construction method, generally, at the construction site, after mixing the resin-based color pavement materials described above by a specified amount with a mixer, etc., transport them to the pavement site by human power or a machine such as a tire shovel, and rake etc. Therefore, the process of manually laying down to the specified pavement thickness and pressing down with a plastering iron for finishing is carried out.

In short, a paving machine dedicated to thin layer paving of resin color paving material has not yet been developed. On the other hand, as a finisher for asphalt pavement used when a general asphalt mixture is used as a pavement material, a structure as shown in FIG. 16 has heretofore been known and put to practical use. In the figure, a is a crawler of the traveling mechanism, b
Is a leveling arm connected to the pivot shaft c of the crawler a and arranged rearward, d is a screw scraper, and e is a screed plate.

[0004]

As described above, in the resin-based color paving material, various resin-based binders such as two-component reactive flexible epoxy resin and acrylic resin are used as the binder as an additive. Therefore, the viscosity of the mixture is several times higher than that of the asphalt mixture during paving, and the mixture becomes sticky. Further, the resin-based color paving material has a property that the curing is promoted with the lapse of time after mixing, the viscosity becomes higher, and the tackiness does not disappear after the curing. Since the resin-based color pavement material has the above-mentioned characteristics and is a thin layer pavement with a pavement thickness of approximately 7 mm to 35 mm,
When the conventional asphalt pavement finisher as shown in FIG. 16 is used, the following problems are pointed out. When the resin-based color paving material is used, it is badly attached to the hopper that holds the asphalt mixture and the bar feeder that conveys the asphalt mixture from the hopper to the screed plate e of the paving mechanism. In particular, regarding the bar feeder, due to the strong adhesion of the resin-based color paving material, the aggregate is caught between the bar feeders,
There is a drawback that the material cannot be fed uniformly. The paving material adhering to the hopper and the bar feeder is removed by cleaning after construction, but this cleaning is very difficult due to its structure and cannot be sufficiently cleaned. The pavement material that could not be removed by cleaning then adheres and hardens, causing a decline in machine function. In the conventional screw scraper d, the adhesion of the resin-based color pavement material is so bad that it cannot be laid smoothly. In the conventional planar screed plate e, the length L of the leveling surface is as long as about 30 cm, so that the resin-based color paving material with strong adhesion adheres to the screed plate surface and drags to the paving finish surface. Occurs, and the pavement surface is roughened.

Due to the above-mentioned disadvantages and problems, it is very difficult to apply a resin-based color paving material to a conventional asphalt paving finisher for mechanization. Accordingly, an object of the present invention is to receive a resin-based color paving material in a hopper, automatically convey the paving material to a leveling mechanism (screed plate), level it to a predetermined thickness, and finish it. It is an object of the present invention to provide a paving machine having a series of paving functions and to which a resin-based color paving material can be applied. Furthermore, in order to prevent the adverse effects of strong adhesion, which is a characteristic of resin-based color paving materials, a polyethylene board on which the resin-based color paving material is non-adhesive is attached to the hopper, feeder, and screw scraper to form a screed. By improving the shape of the plate and further heating the screed plate surface by electric heating, it is possible to prevent the adverse effects due to the adhesion of the paving material and enable thin layer paving.
Moreover, it is an object of the present invention to provide a paving machine for thin-layer paving of resin-based color paving material, which finishes the paving surface cleanly.

[0006]

As a means for solving the above-mentioned problems of the prior art, a paving machine for thin layer paving of a resin-based color paving material according to the present invention is shown in FIGS.
As shown in the example in FIG. 4, a traveling mechanism that is self-propelled on the road by power, a hopper 3 of the resin-based color paving material 20 equipped on the traveling mechanism, and the hopper 3 for resin-based color paving. A belt conveyor type feeder 4 for supplying an appropriate amount of the material 20 to a front portion of a screw scraper 5 for leveling, which will be described later, and a predetermined height above the road surface at a rear portion of the traveling mechanism at a position substantially perpendicular to the traveling direction. The screw scraper 5 for leveling, which is horizontally installed in h and is driven to rotate in a certain direction, and the screw scraper 5 which is located further rearward than the screw scraper 5 and is located at a height h corresponding to the pavement thickness from the road surface. A board 1 which is composed of a screed plate 8 and on which the resin-based color paving material 20 does not adhere to the inner surface of the hopper 3, the surface of the feeder 4, and the blade surface portion of the screw scraper 5. It is affixed, and said screed plate 8 is characterized in that flat part 8b following the front portion of the curved surface 8a is formed relatively short.

In the paving machine of the present invention, a vibration exciter 21 is attached to the screed plate 8, and skis 22 having a height h substantially equal to the paving thickness are provided downward on both sides of the screed plate 8. In addition, the roller 30 whose rotation speed and rotation direction can be freely switched in both forward and reverse directions by the arrangement close to the rear part of the screed plate 8 and whose height and distance between the screed plate 8 and the screed plate 8 can be adjusted is substantially It is installed horizontally, and the heater cable 27 is laid on the entire surface of the screed plate 8 in contact with the resin-based color paving material 20, and the temperature is raised to a temperature at which the sliding property with the paving material 20 is increased by a thermostat. Each is also characterized by management.

[0008]

[Operation] Inside of hopper 3, conveyor type feeder 4
The non-adhesive resin-based color paving material 20 is attached to the surface of the belt and the blade surface portion of the screw scraper 5 in FIG. Harm is prevented in advance. Further, the feeder 4 can perform smooth and uniform feeding without causing clogging or biting of the paving material. Cleaning after use is relatively easy and reliable. Feeder 4
The paving material supplied to the front part of the screw scraper 5 by the feed (transverse feed) action is smoothly and reliably carried out without adhering to the blade surface portion of the screw scraper 5. . The paving material 20 that has been spread evenly on the roadbed by the screw scraper 5 is subsequently pressed by the curved surface 8a at the front part of the screed plate 8 and the aggregates mesh with each other to increase the material density (FIG. 8). ). Further, the flat portion 8b of the screed plate 8 excited by the vibration exciter 21 further increases the density and receives a compaction effect to spread the layer to a predetermined layer thickness. The paving thickness of the paving material is the height h of the ski 22 of the screed plate 8.
Is mechanically defined as (FIG. 10). Lateral spillage of paving material is also prevented by the ski 22.
The curved surface 8c at the rear end of the screed plate 8 prevents unnecessary adhesion and rolling up due to the adhesiveness of the paving material (FIG. 8). Roll 3 located behind screed plate 8
0 excludes the paving material that tends to adhere to the rear end of the screed plate 8 (FIG. 13). At the same time, the finish is improved by the action of stroking the surface of the paving material laid on the roadbed. The screed plate 8 electrically heated by the heater cable 27 reduces the adhesion of the resin-based color paving material 20 and improves the finishing effect on the paving surface (FIGS. 12 and 14).

[0009]

EXAMPLES Next, examples of the present invention shown in FIGS. 1 to 14 will be described. The paving machine shown in FIGS. 1 to 4 has a resin system at the front part on a traveling mechanism (mechanism including vehicle body elements) that travels on an endless track (crawler) 2 driven by a power unit 1 such as an internal combustion engine. A hopper 3 for accommodating the color paving material is provided, and the hopper 3 is divided into two at the center thereof, and the paving material in the hopper 3 is placed in a rearward direction in the traveling direction. A belt-conveyor-type feeder 4 for supplying an appropriate amount to the front part of the hopper 5 is installed in a gap portion at the bottom of the hopper 3. The traveling mechanism is operated by an occupant 7 who rides on a board 9 at the rear of the vehicle body by steering a steering wheel 6. The leveling screw scraper 5 is located at a position just behind the endless track 2 described above.
It is placed at a right angle to the traveling direction, and is installed substantially horizontally from the roadbed surface at a height h slightly larger than the pavement thickness (about 7 mm to 35 mm). This screw scraper 5
The paving material, which is rotatably driven in a forward / reverse bidirectional manner by the power guided from the power unit 1 described above by a transmission mechanism (not shown), and sent to the substantially central portion by the feeder 4 to both outsides. Laying is performed by the action of lateral feeding.
Therefore, the spiral direction of the screw scraper 5 is formed in the opposite direction with the central portion as a boundary. A screed plate 8 is installed at a position further rearward than the screw scraper 5 at a height position h corresponding to the above-mentioned pavement thickness from the roadbed surface.

As shown in FIG. 5, the above-mentioned hopper 3 has its inner edges connected to the vehicle body by hinges 10 on both sides of the feeder 4 located in the gap at the center bottom, so that it is as if a bird were winged. Is installed so that it can be swung as if it had been expanded (see also FIGS. 3 and 4). The other end of the hydraulic jack 12 whose one end is supported by the bracket 11 on the vehicle body side by a pin is pin-connected to the hopper 3 (FIG. 3), and the hopper 3 is supported by the hydraulic jack 12 and as shown in FIG. It is configured to be tiltable and foldable. Therefore, the hopper 3 can optimally adjust the movement (supply) to the feeder 4 by changing the inclination angle according to the amount of the paving material stored.

As shown in FIG. 7, a sheet 1 having a thickness of 2 mm or more, which is made of an ultra-high molecular weight polymer (ultra-high molecular weight polyethylene) to which a resin-based color paving material is non-adhesive
As shown in FIG. 5, a polyethylene board 15 having the four bonded to each other is bonded to the inner surface of the hopper 3 and fixed by means such as fastening the fastening position with a bolt 16. Therefore, the resin-based color pavement material with strong adhesiveness contained in the hopper 3 smoothly moves to the feeder 4 according to the progress of the feeding action by the feeder 4, and the stagnation and clogging of the pavement material are prevented. Therefore, the cleanability is improved. As shown in FIGS. 5 and 6, the configuration of the portion of the hopper 3 in the vicinity of the feeder 4 is such that the inner edge of the piece 18 is undulated by a hinge 17 on the base of the hopper 3, and the piece 18 is made of a rubber plate 19 It is configured to be pasted together with. That is, during normal paving work, as shown by the solid line in FIG. 5 and also shown in FIG. 6, the piece 18 is laid down so that the rubber plate 19 is in contact with the surface of the feeder 4, and the entire width (belt width) B of the feeder 4 is set. On the other hand, a paving material conveyed by the feeder 4 forms a supply gap having a narrow width b in which there is no fear that the paving material is spilled to both sides of the feeder 4. Therefore, it is possible to prevent the inconvenience that the paving material that is transported by the feeder 4 and supplied to the pavement mechanism at the rear enters the inside of the mechanism of the feeder 4 during transportation. on the other hand,
At the time of cleaning after the paving work is finished, the piece 18 is erected as shown by the chain double-dashed line in FIG. 5, so that the cleaning work inside the feeder 4 and the machine can be easily carried out in every corner.
The above-mentioned non-adhesive polyethylene board 15 (FIG. 7) is also attached to the surface of the piece 18. It is also effective to omit the rubber plate 19 shown in FIG. 6 and implement the configuration in which the piece 18 directly and softly contacts the feeder 4.

The feeder 4 is a so-called belt conveyor. Further, it is configured as a bar feeder in which a large number of feed bars 4a oriented substantially at right angles to the traveling direction are attached to the outer surface of the belt 4b at a constant pitch. As shown in the enlarged view of FIG. 9, a polyethylene board 15 to which the above-mentioned resin-based color paving material 20 is non-adhesive is adhered to the surfaces of the belt 4b and the feed bar 4a, and the resin-based color with strong adhesiveness is used. The paving material 20 is carried along with the recesses between the feed bars 4a located in the front and rear on the feeder 4, and is smoothly dropped at the end.

Although not shown in the drawing, the polyethylene board 1 on which the above-mentioned resin-based color paving material is non-adhesive is adhered to both sides of the blade surface of the screw scraper 5.
5 is attached. Therefore, the feeder 4
The resin-based color paving material 20 having strong adhesiveness that has been conveyed from the hopper 3 by the screw scraper 5 is fed laterally to both sides by the rotation of the screw scraper 5 and is spread (unrolled). Also, the harmful effects caused by the adhesion of the paving material are prevented in advance, and a smooth and appropriate leveling effect is achieved.
Further, cleaning after the paving work is remarkably easy to perform and maintenance is good.

Next, the screed plate 8 is suitable for pressing the paving material, the front portion of which is spread by the screw scraper 5, to sufficiently mesh the aggregates with each other to increase the material density. It is formed on the curved surface 8a having a relatively large radius (a radius of about 150 mm). Subsequently, a flat portion 8b having a length of about 100 mm in the traveling direction is formed in the tangential direction, and the rear end portion has a radius of about 10 mm so as to prevent undesired adhesion or dragging due to the adhesiveness of the paving material and winding. Is formed on a small curved surface 8c (having a roundness) (FIG. 8). A vibrating machine 21 is installed on the screed plate 8, and the exciting action of the vibrating machine 21 mainly excites the paving material by vibrating the paving material to further increase the density and improve the flatness of the paving material. A paving thickness (about 7 mm to 35 mm) is formed. The shaker 21 is configured as a switching type between vertical vibration and horizontal vibration, and selects and uses a vibration mode effective for thin layer paving and finishing of paving material.

The setting of the pavement thickness is mechanically defined as the height h of the ski 22 mounted on both sides of the screed plate 8 in parallel with the traveling direction as shown in FIGS. The pavement thickness can be changed by exchanging and changing the height. This screed plate 8 has a bearing arm 23 whose one end is pin-connected to the frame of the endless track 2, as is apparent from FIGS.
It is installed in a suspended form via a height adjusting mechanism 24. By rotating the handle 24a of the height adjusting mechanism 24, the height position of the screed plate 8 can be finely adjusted. The rear portion of the bearing arm 23 is connected to and supported by the other end of a hydraulic jack 26, one end of which is pin-connected to the vehicle body. Therefore, the height position of the screed plate 8 can be largely changed or fixed by expanding and contracting the hydraulic jack 26 through the control of the hydraulic circuit.

Next, in FIG. 12, heater cables 27, which generate heat when energized, are arranged in a meandering pattern on the inner surface of the entire surface of the screed plate 8 in contact with the paving material, and the heater cables 27 are separated. An example of a configuration in which a generator 29 is connected via an electric board 28 is shown. The heater cable 27 uses a thermostat (not shown) and is electrically heated and temperature-controlled so as to enhance the slipperiness of the resin color paving material 20. Distribution board 2
8 and the generator 29 are installed in the position and arrangement of FIG. 1 with respect to the vehicle body. The reason and significance of heating the screed plate 8 is to prevent the adverse effects of the strong adhesion of the resin-based color paving material. That is, the resin-based color pavement material 20 uses, as a binder, a two-component mixed type flexible epoxy resin of a main agent and a curing agent, and the curing is accelerated with time after the two-component mixing. When the workable time range shown in FIG. 15 is exceeded, the curing time band is reached, and the curing of the paving material is accelerated. From the mixing process to the workable time range, when the epoxy resin is heated, it will not cure immediately, but the viscosity of the resin will once drop and the adhesive force (stickiness)
Tends to decrease. After the workable time range, heating accelerates hardening and improves the adhesive force (stickiness), but in the walkable time range, the epoxy resin hardens and loses adhesiveness. Paying attention to the characteristics of such a thermosetting epoxy resin, by heating the surface of the screed plate 8 for pavement, leveling and finishing, the adhesive force of the paving material is reduced, and the adhesion to the surface of the screed plate 8 is reduced. The prevention effect improves the finishing effect on the pavement surface.

A heater cable (heating wire) 2 for the heating means
The reason why 7 is used is that the temperature can be kept constant and the temperature can be easily controlled, and the surface of the screed plate 8 can be uniformly heated and kept warm. Uniform heating and heat retention can be performed by appropriately arranging the heater cables 27, and the temperature can be controlled within ± 1 ° C by a thermostat. The heating temperature is about 80 to 100 ° C., and the temperature is controlled within ± 1 ° C. by a thermostat so as not to drop below the set temperature. The standard wiring pitch of the heater cable 27 is about 10 mm to 30 mm, and the wiring is arranged at a pitch that enables better heating and temperature control. The wiring direction is not only the vertical direction shown in FIG. 12, but also the wiring is carried out in the transverse direction although not shown. The periphery of the heater cable 27 and the inside of the screed plate 8 are filled with a heat insulating material to keep the heat so that the heat retaining effect due to heating does not decrease. As described above, the heating temperature of the surface of the screed plate 8 is set to about 100 ° C., but the heating temperature is controlled according to the type and properties of the thermosetting resin used as the binder of the paving material, and it is effective in preventing adhesion. Set and manage the typical heating temperature. Heating at around 100 ° C does not cause quality deterioration of the paving material. The heating of the paving material 20 by the screed plate 8 results in a paving thickness of 7
Even if the thickness is about 30 mm to 30 mm and the speed of the paving machine is taken into consideration, the same portion is not heated for 30 seconds or more, and deterioration of the resin is not considered. The heating temperature is not locally heated due to the control of the electric heating system.

Next, FIGS. 13A and 13B show an arrangement in the vicinity of the rear portion of the screed plate 8 having the above-described structure and function, in which the rotational speed and the rotational direction can be freely switched between the forward and reverse directions and the height can be freely changed. And the distance k from the screed plate 8
An example is shown in which the adjustable roller 30 is installed substantially horizontally. As shown in FIG. 8, the screw scraper 5 is fed into the front part of the screw scraper 5 and
The resin-based color pavement material 20 spread over the surface of the screed plate 8 is pressed by the curved surface 8a of the front part of the screed plate 8 to increase the density and improve the meshing of the aggregates, and further, the vibration on the screed plate 8 is applied. The density is further increased by the vibration of the machine 21. The resin-based color paving material 20 thus increased in density has a predetermined paving thickness on the flat surface portion 8b of the screed plate 8, and then adheres to the rear portion of the screed plate 8 by the roller 30 attached to the rear of the screed plate 8. The pavement material is removed. In particular, when the roller 30 is rotated in the direction opposite to the traveling direction, the roller 30 rubs the surface of the paving material to greatly enhance the finishing effect. This is comparable to the finishing effect of plastering iron during manual construction.

In the standard condition of pavement construction, the bottom surface of the screed plate 8 and the bottom of the roller 30 are placed at the same height and the paving material is laid. If the finish of the aggregate grain type of the paving material is confirmed and the finishing effect cannot be recognized, the bottom of the roller 30 is slightly lowered (tmm) as compared with the screed plate 8 as shown in FIG. 13A, and the finished surface of the paving material 20. The effect of pressing and stroking the upper part with the roller 30 is improved, and the finished surface is improved. The distance k between the screed plate 8 and the roller 30 is finely adjusted in the front-rear direction by blending the resin-based color paving material 20. When the amount of mortar is large, the gap k between the screed plate 8 and the roller 30 is widened to prevent the gap between the screed plate 8 and the roller 30 from being clogged with resin or mortar. Since the rotation speed of the roller 30 can be freely changed, it can be adjusted to an optimum rotation speed while checking the finished surface according to the paving material used and the traveling speed of the paving machine. The pavement material adhering to the surface of the roller 30 may be removed by pressing a cloth-like auxiliary roller, which is obtained by impregnating the surface of the roller 30 with a release agent, onto the surface of the roller 30 by the action of a spring or the like. FIG. 14 shows an embodiment in which a heater cable 27 is provided not only on the screed plate 8 but also on the surface of the roller 30 to perform heating control of an electric heating system.

Therefore, it is possible to prevent the adverse effect of adhesion when the resin-based color paving material 20 is housed in the hopper 3. Similarly, since the polyethylene board 15 is attached to the surface of the feeder 4, it is possible to prevent the paving material from being clogged or caught during the feeding by the feeder 4, and the resin-based color paving material 20 can be smoothly fed in appropriate amounts. it can. Furthermore, since the polyethylene board 15 is also attached to the blade surface portion of the screw scraper 5, the paving material 20

The screed plate 8 has a curved front surface 8a and a short flat surface portion 8b, and the resin-based color paving material 20 having strong adhesiveness is laid to a predetermined thin layer paving thickness for compaction effect and surface finishing. As a result, the series of work that has been performed until now, such as leveling and surface finishing with human power, are all mechanized, and efficiency can be improved and labor and labor can be greatly saved. In particular, while the resin-based color paving material 20 has strong adhesion, the screed plate 8 is appropriately heated to prevent the resin-based color paving material 20 from adhering to the surface and improve the pavement finish surface (material dragging). (Prevention) and heating effect (heat quality improvement). In addition, since the vibrating machine 21 excites the screed plate 8 to perform compaction and finishing while adjusting the type and strength of vibration, it is possible to support the resin-based color paving material 20 and is suitable for each material. By selecting the vibration, the compaction density can be improved.

Further, for the resin-based color paving material 20 having a strong adhesion viscosity, the screed plate 8 and the roller 30 are combined to prevent the harmful effects due to the adhesion, and it is consistently laid and finished to a predetermined thickness. It is possible to do. Since the roller 30 can freely change the height of the bottom surface and the displacement in the front-back direction, it can be applied to various resin-based color paving materials 20 and various aggregate particle types.
