Description

  The present invention relates to a road repair work apparatus and a road repair work method, and more particularly to a road repair work apparatus and a road repair work method for eliminating road surface steps that have been used for many years and occur in the process of repairing a road surface.

Among road construction works, road laying that forms the surface of roads is almost free of road surfaces except in special environmental areas because there is little noise such as automobiles, the construction period is short, and construction is simple and inexpensive. Is asphalt paved.
In this asphalt road, the road surface wears out over many years, and a dent is formed, or cracks are caused by repeated weight load, which causes noise generation of the traveling car, Repairing the road that has been used for a certain period of time, especially its surface, is indispensable because it may interfere with the safe driving of the car.

Most of the repair work does not work from the foundation, but pavement work on the surface layer including the pavement surface. In this paving work, a portion corresponding to the surface layer of the road is once peeled off, and then the peeled portion is newly paved to finish the entire road surface flat.
In this case, along the length of the road, there are parts that will be repaired and parts that will not be repaired, in other words, where repair work is necessary (repair section) and where repair work is not required (non-repair section). Will exist.

Also in the width direction of the road, lanes with a large amount of automobile traffic and lanes with a relatively small traffic volume, in particular, the outer driving lane and the inner overtaking lane, or heavy vehicles depending on the region Is designated to pass through the inner lane, and the road surface life tends to be relatively short in the inner lane, so repair work is often performed first from the inner lane.
For example, when the surface layer of the inner lane of the road is stripped, a step corresponding to the thickness of the stripped surface layer is formed between the non-repair section and the repair section.

This level difference will exist until the repair work is completed, and for a passing vehicle, the wheel is dropped when the vehicle crosses the lane, and the driver or the passenger feels an unpleasant shock.
Therefore, it is required to make the road surface such that the vehicle passing there does not feel this step until the repair work is completed.

First, as shown in FIG. 7 as a cross-sectional view of the road, the repair section h of the road is changed to the repair section h between the non-repair section f and the surface layer portion hy of the worn road. A step d that is lower than that of the first step is formed.
When the vehicle travels through the step d, the vehicle's heel may drop, or when the vehicle gets over the step, a shock may occur, which may reduce the riding comfort of the vehicle.
Moreover, although the above description gave the example in which the non-repair section f and the repair section h exist in parallel in the width direction of the road, as shown in FIG. Even when the entire surface is repaired, a step d is produced between the edges of the side grooves s.
In any case, the step is forced to be formed by peeling off the surface layer of the repair section.

  In order to eliminate the level difference formed in the process of such repair work, several ideas have been tried. The first one is shown in Japanese Patent Publication No. 7-88648 listed in Patent Document 1, and moves while rotating a pressure member having a tapered surface that rotates an edge in the length direction of a new road. In this way, an inclined surface is formed along the edge of the new road. The invention disclosed therein intends to eliminate a step generated when a new road is laid, and forms a slope at an edge portion before the laid portion is cured. However, since there is a non-repair section f that has already hardened in the road repair work, a slope cannot be formed at this edge portion.

Further, in the invention disclosed in Japanese Patent Laid-Open No. 9-13307 cited in Patent Document 2, a rubber mat having an inclined surface that becomes lower toward the center side of the road with respect to the step d formed in the repair section. Is laid along the length direction of the road to eliminate the level difference formed by the repair work and smooth the passage of the vehicle.
However, what is shown in this prior invention is effective in the case of a relatively short working length, but it is difficult to lay a rubber mat over a long working section of several hundred meters. Further, it is necessary to remove the rubber mat after the work is completed, and the work is time-consuming and time-consuming, and energy is consumed to transport the rubber mat to the work place.

Further, in the invention disclosed in Japanese Utility Model Laid-Open No. 5-10509 listed in Patent Document 3, as in Patent Document 2, an operation called “slipping” is omitted using a patch corresponding to a rubber mat, and a step is provided. However, it can be applied only to roads with relatively short working sections, and to work on limited places such as around manholes. However, it is not suitable for repair work on roads with long work sections.
Japanese Patent Publication No. 7-88648 JP-A-9-13307 Japanese Utility Model Laid-Open No. 5-10509

  Therefore, the present invention makes it easy to carry out construction work during road repair work, and to easily form the steps formed in the repair work section even if the work target section is a long work section of several hundred meters. It is an object of the present invention to provide an apparatus and a method that can be eliminated and that can perform construction that does not require removal work after the work is completed.

Moreover, it is possible to continuously perform the step elimination work on the repair work road, and to perform an efficient work. Furthermore, there is an effect that, after the work is done, after-work is not required, such as removing what has been laid once.

Here, in the present invention, it is preferable that the pressure-suppressing frame is suspended and supported on both the left and right sides in the working direction, and the left and right of the pressure-suppressing frame are independently moved up and down. In the present invention, it is preferable that the pressure suppressing frame is supported so as to be suspended and supported at two positions on the left and right side surfaces in the working direction.
Further, both the left and right sides of the pressure reducing frame in the working direction are supported by a cylinder rod of a hydraulic cylinder via a ball joint, and driving the hydraulic cylinder causes the left and right sides of the pressure reducing frame to move up and down independently. It is desirable to configure.
Furthermore, the left and right sides of the working travel direction of the crush frame, with are respectively supported by one end of the support member via a ball joint, the hydraulic cylinder cylinder rod is connected to the other end of the respective support member, wherein By extending and retracting the cylinder rod of the hydraulic cylinder in the working direction, each of the left and right support members pivots about one point of the support member, so that the left and right sides of the pressure reducing frame can move up and down independently. It is desirable to configure.

  In this way, the crushing frame is configured so that the left and right can move up and down independently. Can be eliminated.

In the present invention, the pressure suppressing frame is supported by the links on both the left and right sides of the front side in the working direction and supported by the plate so as to be tiltable in the left and right directions at the center of the rear side. It is preferable that one end of the pressure cylinder is connected to a cylinder rod of the hydraulic cylinder so that the pressure suppression frame is inclined by swinging the link, and the pressure suppression frame is moved up and down by driving the hydraulic cylinder.
Since it is comprised in this way, while being able to make the suppression frame into an inclined state, the said suppression cylinder can be moved up and down with a hydraulic cylinder. As a result, the pressure reducing frame can eliminate the step by pressing and leveling the repair material such as asphalt supplied to the step portion by its own weight in a slope shape.

Moreover, it is preferable that the said suppression frame is formed in planar view square shape, and the circumference | surroundings of the said drop port are enclosed by the frame board .
In this way, since the drop opening is surrounded by the frame plate, even if supply unevenness occurs in the supply of road repair material, it can be temporarily stored in the pressure-reducing frame, and a step elimination part that is a continuous inclined surface can be formed. it can.

In the present invention, it is preferable that the hopper is mounted and a tilting base provided to be tiltable with respect to the slider and a tilting mechanism for tilting the tilting base with respect to the slider are provided.
Since the hopper is tilted with respect to the vehicle body in this way, the operator can easily check the outlet for the road repair material formed on the hopper bottom, and the center of the hopper Road repair materials can be supplied appropriately. Further, the operator can easily check the remaining amount of road repair material inside the hopper. Moreover, the repair material adhering to the inner wall of the hopper can be easily cleaned.

In particular, the motor includes a motor provided on the tilt base and a hopper base formed with a gear meshing with a gear attached to the motor, and the hopper mounted on the tilt base includes the motor. If it is configured to be rotatable , the outlet for the road repair material can be rotated with the hopper loading the repair material tilted with respect to the vehicle body, and the outlet for the road repair material can be checked more It is easy to check the remaining amount of road repair material inside the hopper, and the repair material attached to the inner wall of the hopper can be more easily cleaned.

In addition, the present invention supplies repair materials such as asphalt along the step formed in the process of repair work at the boundary between the repair section and the non-repair section, and the non-repair section side is high, the repair section side This is a road repair work method that works so as to eliminate the step by forming an inclined surface so as to lower the level.Therefore, a step eliminating part having an inclined surface by the repair material is provided between the non-repair area and the repair area. Since it forms, the level | step difference formed in a repair road can be removed, and there exists an effect which can maintain the passage of a vehicle smoothly.

The road repair work device of the present invention forms an inclined surface continuously along the length direction of the repair road by simply moving one side of the suppression frame on the non-repair road with respect to the repair work road. Therefore, it is possible to efficiently perform the step elimination work.
Further, the present invention can press and level the repair material such as asphalt supplied to the step portion by its own weight of the pressure suppressing frame, and can eliminate the step. In addition, there is an effect that no post-work such as a withdrawal work is required even after the work.
Further, according to the present invention, even if there is a large or small amount of unevenness in the repair material supplied at the stepped portion, the pressure suppression frame is inclined to the left and right along the work traveling direction, and is moved up and down to the posture. Since it can change, the level | step difference elimination part can be continuously formed in the edge of repair work area.

  First, FIG. 1 is a basic configuration diagram showing an exploded road repair work apparatus according to the present invention. This road repair work device can be broadly divided into a hopper that has the function of loading repair materials and supplying them for use in step resolution, and smoothly supplies the repair materials supplied from the hopper to the repair work target position. Supply control mechanism for reducing the level of the repaired material at the stepped portion of the supplied repair material, and a pressure reducing frame that functions to reduce the surface and form an inclined surface. It is comprised by the vehicle body which can be mounted and can move suitably.

Next, each configuration will be described.
First, in the figure, reference numeral 10 denotes a hopper. This hopper 10 has a square shape in a plan view, and is formed by a side plate 11 whose upper end edge is widened and inclined. Further, the side plate 11 can be opened outward by a hinge 12 at a substantially intermediate position.
As described above, the side plate 11 of the hopper 10 can be rotated outwardly by the hinge 12 along the vertical plane at a substantially intermediate position, so that the opening area of the hopper 10 can be expanded not only in a plane but also in a side surface. The loading work when supplying the repair material to the hopper 10 is facilitated.
In addition, although the hinge 12 may be provided in all the side plates 11, as shown in FIG. 2, you may provide the hinge 12 only in one set among the side plates 11 which oppose. In this case, the hydraulic cylinder 11a is attached to the outer side surface of the side plate 11 on which the hinge 12 is not provided, and the end of the cylinder rod 11b is attached to the side plate 11 on the hinge 12 so that the hydraulic mechanism can move the upper side of the hinge 12 to the side. The face plate 11 can be hinged to the outside.

  The lower portion of the hopper 10 is a base portion 13 having a cylindrical space surrounding the periphery. The base 13 is circular in order to change the posture of the hopper 10 by rotating in plan view, but as described above, the side plate 11 forming the hopper 10 is opened outward by the hinge 12, It may be formed in a rectangular shape instead of a circular shape scheduled for rotation.

  Further, the lower portion of the base portion 13 becomes a continuation portion 14 that connects the supply control mechanism 20 and the hopper 10 described below. The continuation portion 14 has a shape that can cover the periphery of the repair material supplied from the hopper 10 so that the repair material does not spill outside during the process of dropping and moving to the supply control mechanism 20. Although not shown, the continuation unit 14 may be provided with a heat retaining unit made of a burner or the like for heating a repair material made of a composite material such as asphalt.

  The supply control mechanism 20 has a hopper 21 similar to the hopper 10, and the bottom of the hopper 21 has a funnel shape, the lower end of the hopper 21 has a cylindrical shape, and is continuous with a supply portion 22 that is rectangular in plan view. The supply unit 22 is used to smoothly supply a repair material dropped and supplied from the hopper 21 to a pressure-suppressing frame, which will be described later, via a lower opening / closing mechanism. A pair of switches 23 are attached. As shown in FIGS. 1 and 2, the grab bucket type opening / closing machine 23 is supported by a support part 23a via a pin 23b so as to be opened and closed, and each upper part of the support part 23a is supported by hydraulic means in the direction of the arrow. By pulling, it opens and closes like a spear. The opening / closing machine 23 temporarily stores the repair material and can supply the repair material in a timely and appropriate amount to a pressure suppression frame to be described later.

  These are mounted via a mount 42 provided on the vehicle body 40, and can be moved by the vehicle body 40 having wheels 43.

The opening of the opening / closing machine 23 is open to the pressure reducing frame 30, and by opening the opening / closing machine 23, an appropriate amount of repair material can be supplied in a timely manner. The pressure-reducing frame 30 has a square shape in plan view, is surrounded by a frame plate 31, and has a central opening serving as a repair material dropping port 33 in an open window state. The drop opening 33 is set to have an area wider than the opening area (opening area) in a state where the opening / closing machine 23 is fully opened.
A guide portion 32 is formed at the lower end edge of the frame plate 31 so as to have a rim-like periphery. The front end portion and the rear end portion have a skid shape so as not to become a resistance during movement. A guide end 32A is formed with the guide end standing in a curved surface.

In the pressure reducing frame 30, the repair material is supplied to the drop port 33 surrounded by the frame plate 31 located at the center thereof, and once accumulated in this space, the lower edge of the frame plate 31 is moved while being moved along with the movement of the pressure reducing frame 30. The repair material is supplied to the repair location from the gap between 31A and the repair location.
Further, the pressure suppressing frame 30 is formed by the guide portion 32 formed so as to spread along the lower end edge 31A of the frame plate 31 forming the pressure reducing frame 30 to level the repair material H supplied to the step portion during the movement accompanying the repair work. However, it can move with less resistance while being suppressed by its own weight. Since the guide portion 32 is formed so as to extend along the lower end edge 31A of the frame plate 31, it is formed in a round shape, and the lower surface of the guide portion 32 constitutes a pressure surface.

In particular, as shown in FIGS. 2 and 4, the pressure suppressing frame 30 is suspended and supported by the hopper 21 via left and right suspension wires 34L and 34R. Each end of the wires 34L and 34R is divided into two and fixed to support points 35L and 35R provided at two left and right positions and two front and rear positions on the frame plate 31.
Accordingly, if the lengths of the left and right suspension wires 34R and 34L are equal, the pressure suppressing frame 30 maintains a horizontal state and changes the suspension length of the left and right suspension wires 34R and 34L so as to be inclined in the lateral direction. Can take. Actually, if the pressure-suppressing frame comes in contact with the stepped portion, it becomes an inclined posture by its own weight, and one wire is in a loose state.

  In this inclined posture, one side of the left and right side end portions 30L, 30R of the pressure reducing frame 30, for example, as shown in FIG. 3, the left side end portion 30L is placed on the edge of the non-repair section f and the remaining one is repaired section. By setting the h to the grounding state by its own weight from the suspended state, the pressure suppressing frame 30 is inclined in the left-right direction, and the step d formed between the non-repair section f and the repair section h A step eliminating portion D having an inclined surface can be formed.

  Accordingly, the lengths of the left and right suspension wires 34L and 34R can be controlled by the winding wheels 36L and 36R that are rotated by the independent drive portions 38L and 38R via the support wheels 37L and 37R, respectively. Specifically, the left side of the pressure suppressing frame 30 with the end portion placed on the non-repair section f is shortened by the suspension wire 34L, and the right side of the pressure suppression frame 30 is loosened by the suspension wire 34R and its own weight. The end is placed in the repair section h. By taking this posture, both the wires 34L and 34R are changed from the suspended state of the pressure suppression frame 30 to the grounded state and are in a relaxed state, and the stepped portion D made of repair material is formed in the space portion where the step d exists. be able to.

Next, the whole road repair work apparatus of this invention is demonstrated.
As shown in FIGS. 5 and 6, the main part of the vehicle body 40 is configured by a gantry 42 on which the hopper 10, the supply control mechanism 20, the pressure suppressing frame 30, and the engine 41 as a power source are mounted. It is possible to move along the work section via the wheels 43 provided in. Furthermore, at the rear part of the vehicle body 40, there are an operator boarding part 44, and further, operation handles 45 operated by the operator, so that operation of the switching lever 46 of various hydraulic control circuits and the like can be performed together with the steering operation. It has become.

Next, work using the road repair work device of the present invention will be described.
First, the road repair work device is moved to the work position. At this time, the pressure reducing frame 30 is brought into a suspended state by adjusting the lengths of the left and right suspension wires 34L and 34R by the winding wheels 36L and 36R. Specifically, the suspension wire 34L is shortened on the left side of the suppression frame 30 so that the end portion is placed on the non-repair section f, and the suspension wire 34R is loosened on the right side of the suppression frame 30 and repaired by its own weight. The end is placed in the section h to be in a grounded state.
On the other hand, the repair material such as asphalt supplied into the hopper 10 is supplied to the supply unit 22 via the hopper 21 of the supply control mechanism 20 and is stored by the switch 23.

Then, with the pressure suppression frame 30 maintaining the above posture, the opening / closing machine 23 is opened, and the repair material passes through the drop port 33 surrounded by the frame plate 31 positioned at the center of the pressure suppression frame 30, and the lower end edge of the frame plate 31. Supplied to the repair location through the gap between 31A and the repair location. The opening / closing machine 23 is appropriately opened and closed by an operator so that the supply amount of the repair material becomes an appropriate amount.
The repair material is supplied to a space formed between the non-repair section and the repair section, and is leveled by the guide portion 32 of the suppression frame 30 along with the movement of the road repair work device, and is pressed and suppressed by the weight of the suppression frame. In the portion where the level difference d exists, the level difference elimination part D is obtained.

Next, another embodiment of the road repair work device according to the present invention will be described.
In another embodiment, as shown in FIG. 9A, the pressure suppressing frame 30 is not supported by the left and right suspension wires 34 </ b> L and 34 </ b> R but can be rotated by a bent portion with respect to the hopper 21. It is supported by the supporting members 50L and 50R that are supported in a side-view shape.

More specifically, extension parts 31L, 31R having a triangular shape in side view are provided on the left and right sides of the frame plate 31 provided in the pressure suppressing frame 30, and one ends of the support members 50L, 50R are provided above the extension parts 31L, 31R. The support members 50L and 50R are connected to each other via ball joints 51L and 51R, and the other ends of the support members 50L and 50R are connected to cylinder lots 52a of hydraulic cylinders 52L and 52R provided in the hopper 21.
According to this configuration, when the support members 50L and 50R rotate around the support portion by the expansion and contraction of the cylinder lot 52a of the hydraulic cylinders 52L and 52R, as shown in FIG. 9B, the support members 50L and 50R and the frame Since the plates 31L and 31R are connected by the ball joints 51L and 51R, the pressure reducing frame 30 can be inclined in the same manner as the left and right suspension wires 34L and 34R.

Specifically, in a state where the hydraulic cylinders 52L and 52R are unlocked, for example, the left end portion of the pressure reducing frame 30 is placed on the edge of the non-repair section f, and the remaining one is positioned in the repair section h. Thus, the suppression frame 30 is in a grounded state due to its own weight. Thereby, the suppression frame 30 becomes an inclination posture along the left-right direction. And while supplying a repair material to the center space of this suppression frame 30, while pressing a repair material by moving the whole apparatus, the level | step-difference d part formed between the non-repair area f and the repair area h It is possible to continuously form the step elimination part D having the inclined surface.
The moving speed is determined in relation to the supply amount of the repair material, and is determined so that the shortage of the repair material does not occur during the work.

Further, as shown in FIG. 10, the cylinder rods 60a of the hydraulic cylinders 60L and 60R attached to the hopper 21 are directly connected to the left and right sides in the work progress direction of the frame plate 31 of the pressure reducing frame 30 via ball joints 61L and 61R. Also good.
According to this configuration, the pressure suppressing frame 30 can be in an inclined posture with a simple configuration without using the above-described support member having a square shape.

  Furthermore, as shown in FIG. 11, the pressure suppressing frame may be supported by links on the left and right sides of the front side surface in the work progress direction. That is, one end of the links 65L and 65R is attached to the base 64 to which the hopper 21 is attached, and the other end of the links 65L and 65R is attached to the left and right sides of the front side surface of the frame plate 31 with respect to the working direction. It has been.

The pressure reducing frame 30 is supported by a plate 66 and a lever member 67 at the center of the rear side surface of the frame plate 31. One end of the plate 66 is rotatably connected to the connecting portion 31A on the rear side surface of the frame plate 31, and the other end is rotatably connected to one end (plate 67c) of the lever member 67.
The lever member 67 includes the plate 67c, the plate 67b, and a shaft portion 67a that integrally connects the plate 67b and the plate 67c. The shaft portion 67a is rotatably supported by the base 64. ing. The other end (plate 67b) of the lever member 67 is connected to a cylinder rod 68a of a hydraulic cylinder 68 that is swingably attached to the base 64.
The plate 66 is formed with a long hole 66a, and the connecting portion 31A is also formed with a long hole (not shown). Bolts 69a are loosely fitted into these long holes, and a nut 69b is fitted at the tip of the bolt 69a. Are screwed together to prevent the bolt 69a from coming off.

Thus, the bolt 69a is attached to the plate 66 and the connecting portion 67 with rattling, so that the pressure reducing frame 30 can be inclined.
In addition, as shown by an arrow in FIG. 11A, the pressure reducing frame can be moved up and down by driving the hydraulic cylinder 68. Moreover, since it can be operated by one hydraulic cylinder, the cost can be reduced.
Although not shown, it is preferable that the length of either the upper link or the lower link of the links 65L and 65R can be varied. Thus, by varying the length of the link, the height of the front end portion and the rear end portion of the pressure suppressing frame can be changed. That is, the inclination state in the traveling direction of the pressure suppression frame can be varied.

Next, as shown in FIG. 12, a drainage basin H may be provided in a part of the side groove S. In this case, repair work around the drainage basin H, in other words, repair work in the lateral direction (vertical direction) with respect to the work progress direction, or repair work to a position offset from the existing repair work position is performed. Necessary.
However, in the working device in the above-described embodiment, the repair work in the lateral direction (vertical direction) and the repair work to the offset position cannot be performed continuously, the orientation of the work device is changed, or the manual work is performed. Repair work is required.

That is, the positions of the hopper 10, the supply control mechanism 20, and the pressure reducing frame 30 mounted on the slider 80 can be moved in the lateral direction with respect to the work progressing direction.

Next, a tilting mechanism that tilts the hopper 10 and a rotating mechanism that rotates the hopper 10 will be described with reference to FIGS. 17 and 18.
The slider 80 supports shafts 21 a and 21 b provided at both ends of the hopper 21.
Further, the tilt base 81 on which the popper 10 is mounted has the shafts 21a and 21b penetrated and is supported by the shafts 21a and 21b so as to be tiltable. The tilt base 81 is connected to the rod 82a of the cylinder piston 82. The other end of the cylinder piston 82 is connected to the slider 85a. That is, the tilt base 81 is in a horizontal state with the rod 81a of the cylinder piston 82 contracted, and the tilt base 81 is tilted by a predetermined angle θ with the rod 82a extended.

Thus, since the tilting base 81 is tilted, the hopper 10 mounted on the tilting base 81 is also tilted, so that the operator can easily confirm the outlet for the road repair material formed at the bottom of the hopper. The road repair material can be supplied appropriately. Further, the operator can easily check the remaining amount of the repair material inside the hopper. Moreover, the repair material adhering to the inner wall of the hopper can be easily cleaned.
The tilt base 81 is formed with a motor holding portion 81a for holding the motor 83 of the rotation mechanism.

A gear 84 is formed on the base 13 of the hopper 10 and meshes with the gear 83 a of the motor 83. Therefore, the hopper 10 can be rotated by rotating the motor 83.
Since the motor 83 and the gears 83 a and 84 are disposed on the tilt base 81, the motor 83 and the gears 83 a and 84 tilt with the tilt base 81. Since the hopper 10 can be rotated in a tilted state, the operator can more easily check the outlet for the road repair material formed at the bottom of the hopper, and the operator can also check the inside of the hopper. This makes it easier to check the remaining amount of repair material. Furthermore, since the repair material adhering to the inner wall of the hopper 10 can be removed while rotating the hopper 10, the hopper 10 can be easily cleaned each time.
