Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a road surface shape detection device for detecting the shape of a road surface on an asphalt paved road, etc., and in particular is capable of obtaining the cross-sectional shape of the road surface as electrical data.

This type of road surface shape detection device is suitable for use when resurfacing an asphalt road to maintain its original flatness, for example, when the asphalt pavement is rutted and the flatness has been impaired due to weather conditions. It is.

In other words, to perform road surface resurfacing, a road surface heating vehicle is driven in the lead to heat the asphalt paved road surface, and a road surface resurfacing device is driven to follow this, whereby the asphalt surface is formed by the road surface resurfacing device. Do not loosen the paving material (polymerized material) and mix this loosened polymeric material with new asphalt paving material (new composite material), or layer the new composite material on country timber and then spread it evenly. According to
This system maintains a road surface that has lost its flatness to a standard level and regenerates it to a flat road surface.

Here, in order to bring the road surface to the reference level, it is necessary to adjust at least one of the amount of rural wood and the amount of new composite material to adjust the amount of resurfacing composite material to a predetermined value.

Therefore, in order to adjust the amount of old composite material and the amount of new composite material, it is necessary to detect the cross-sectional shape of the original road surface, and there arises a need to apply a road surface shape detection device here.

By the way, as a conventional road surface shape detection means, a road surface contactor that is movable in the road surface width direction and vertical direction is brought into contact with the road surface, and a recording needle is attached to the upper end of the road surface contactor to record the vertical movement of the road surface contactor. The road surface shape was detected by recording it on paper.

However, such conventional road surface shape detection devices simply record the road surface shape on recording paper;
Based on this record, it is not possible to immediately calculate at least one of the amount of old composite material and the amount of new composite material required for resurfacing, and it is also impossible to use the road surface detection data as detection data for the control system. There were some problems that made it impossible to utilize it.

Therefore, the present invention has been made by focusing on the problems of the conventional device, and its purpose is to detect the cross-sectional shape of the road surface as electrical detection data using a road surface shape detection means, and to detect the cross-sectional shape of the road surface as electrical detection data. It is possible to easily calculate the amount of resurfacing mixture material required for road surface resurfacing, and also to automatically perform road resurfacing based on detected data, thereby solving the problems of the conventional device. An object of the present invention is to provide a road surface shape detection device that can detect road surface shapes.

In order to achieve the above object, the present invention includes, for example, a cart 4 movable in the longitudinal direction of the road surface, as in the illustrated embodiment;
A road surface shape detecting means 7 mounted on the bogie 4 and scanning the road surface in the width direction, and obtaining electrical detection data according to the road surface shape from the road surface shape detecting means 7. It concerns a detection device.

The present invention will be explained below based on the drawings.

FIG. 1 is a schematic diagram showing an embodiment of the present invention.

First, the configuration will be described. In FIG. 1, numeral 1 denotes a road surface shape detection device, which is configured as described below.

That is, it has a cart 4 formed in a U-shape from a horizontal rod portion 2 and vertical rod portions 3L and 3R extending downward from both ends thereof, and the vertical rod portions 3. Guide rollers 5L and 5R are rotatably pivoted to the lower ends of L and 3R, respectively. A pulse generator 6 as a rotation detector is attached to the rotating shaft of one guide roller 5R, and the pulse generator 6 outputs a number of pulse signals proportional to the amount of rotation of the guide roller 5R.
is counted.

Furthermore, a road surface shape detection means 7 is mounted on the truck 4. An example of this road surface shape detection means 7 is such that a carriage 9 is slidably guided and supported in the road surface width direction by a guide bar 8 which is bridged between the vertical rod portions 3L and 3R of the bogie 4 in parallel with the horizontal rod portion 2. , has a configuration in which a road surface distance detector 10 for measuring the distance to the road surface is attached at a position facing the road surface.

The carriage 9 is reciprocated in the road surface width direction by the rotation of a screw shaft 12 that is rotationally driven by, for example, a servo motor 11, and its movement position is detected by a rotation detector 13 that detects the rotation of the screw shaft 12. An example of the rotation detector 13 is a photo sensor having a rotation detection plate 14 integrally fixed to the screw shaft 12 and having a through hole bored in the outer circumference, and a light emitting element and a light receiving element facing each other with the rotation detection plate 14 in between. Interrupter 15
The amount of movement of the carriage 9 can be detected from the pulse signal for each revolution of the screw shaft 12 output from the photointerrupter 15 and the pitch of the screw shaft 12. Actually, the pulse signal of the photointerrupter 15 is counted by a predetermined number by the pulse counter 15a to detect that the carriage 9 has reached a predetermined position.

Further, an example of the road surface distance detector 10 uses ultrasonic transmitters 16a and 1 by measuring the time from the time of transmitting the ultrasonic wave until receiving the reflected wave reflected from the road surface.
It has a configuration that measures the distance aXi between 6b and the road surface and outputs the distance measurement data as an electrical data signal.

Note that 17 is a microswitch that detects the left end position of the carriage 9 attached to the vertical rod portion 3L of the truck 4.

As shown in FIG. At the same time, the microcomputer 20 outputs a drive control signal for the servo motor 11 and a recording device 3 to be described later.
o and additional mixed material amount calculation data representing the calculation result to the display device 31 are output.

As shown in FIG. 2, the microcomputer 20 includes an interface circuit 21. It is configured by the arithmetic processing unit 22 and the storage device 23, and specifically includes the vehicle mileage determining means 24 and the carriage positioning means 25 shown in FIG.
．． Road surface distance data storage means 26. A means 27 for determining the end of carriage movement is provided with a means 28 for calculating the amount of mixture material for resurfacing.

Here, the vehicle traveling distance determining means 24 counts the pulse signal of the pulse generator 6 when the trolley 4 starts traveling, and the count value is set to a predetermined value, for example, the pulse signal is 10.
When each count is 0, it is determined that the vehicle has traveled a predetermined distance, and a determination signal representing this fact is output.

The carriage positioning means 25 causes the servo motor 11 to be driven by the determination signal, and stops driving the servo motor 11 every time the number of revolutions thereof reaches a predetermined value. In this case, the carriage 9 moves to the right by the drive of the servo motor 11, and the distance traveled each time is determined by how many minutes in the road surface width direction the distance data is sampled, and the number of samplings is large. It is possible to detect the road surface shape quite accurately.

The road surface distance data storage means 26 sequentially stores the road surface distance data from the distance detector 10 into the storage device 2 every time the carriage 9 is positioned by the carriage positioning means 25.
Store in 3.

The carriage movement end determination means 27 outputs a movement end determination signal when the carriage 9 reaches the right end position. For example, when the number of data samplings in the distance data storage means 26 reaches a predetermined value, the carriage 9 reaches the right end position. The end of movement determination signal is output indicating that the end of movement has been reached.

The resurfacing material amount calculating means 28 calculates a plurality of distance data Xi stored in the road surface distance data storage means 26 based on the movement end determination signal from the carriage movement end determination means 27.
(i=L2...n) is read out, and based on these, the travel distance stored in advance, and the road surface width W, the amount S of additional mixed material for resurfacing is calculated according to the following formula.

S − [(Σ (Xi −Xo) ) /n ・
L-WL: 1 ・・・・・・・・・・・・(1) However, Xo is the ultrasonic transmitter 16 of the distance detector IO,
This is the distance between a and the reference road surface R.

30 is the amount of resurfacing material for the microcomputer 20/
A recording device 31 receives and records additional material amount data indicating the additional material ls based on the calculation result of the 1iliW means 28, and a recording device 31 similarly receives additional material amount data from the microcomputer 20 and displays it. It is a display device.

Next, the effect will be explained. First, the guide rollers 5L and 5R of the road surface shape detection device 1 are brought into contact with the reference road surface R, for example, the L-shaped groove 33 and the center line 34 position of the road shoulder.

In this state, when the road surface shape detection device 1 is driven by an appropriate means, first, the vehicle travel distance determination means 24 of the microcomputer 20 is activated, and based on this, the carriage positioning means 25 is activated. For this reason, carriage 9
moves sequentially from the left end to the right by a predetermined distance and then stops.

Then, each time the carriage 9 stops, the distance data storage means 26 is activated and stores the road surface distance data from the road surface distance detector 10 in the storage device 23.

When the carriage 9 reaches the right end by repeating the above operations, a movement end determination signal is output from the carriage movement end determination means 27, and based on this, the resurfacing mixture amount calculation means 2
8 is activated. For this reason, the resurfacing material amount calculation means 2
In step 8, the required additional material amount S for a predetermined moving distance of the road surface shape detection device 1 is calculated according to the above equation (1), and the calculated data is stored in a predetermined area of the storage device 23.

The additional material amount calculation data stored in the storage device 23 is supplied to the recording device 30 via the interface circuit 21 and recorded, and at the same time, the additional material M calculation data is supplied to the display device 31 and displayed. be done. In this case, the recording in the recording device 30 and the display in the display device 31 record and display the amount of additional mixed material required for resurfacing in digital values.

Note that the road surface distance data stored in the storage device 23 by the distance data storage means 26 is directly sent to the recording device 30 and recorded as road surface distance data representing the cross-sectional shape of the road surface for each scan of the carriage 9. Alternatively, the distance data may be similarly sent to the display device 31, and the display device 31 may perform graph ink processing to display a graph ink display representing the cross-sectional shape of the road surface.

In addition, by setting in advance the distance Xf between the bottom surface and the road surface distance detector 10 when the road surface is loosened, (Xf

FIG. 4 shows this processing procedure. When the road surface shape detection device 1 starts running with its own blade or with another running vehicle, the program starts strongly and steps
First, a drive control signal for driving the thermomotor 11 in forward rotation is output, and the gears 1, 7, and 9 are moved to the right.

And Ste Nobu ■ G Koite Photo Interrupter 15
The pulse counter 15a's pulse counter 15a, which is supplied with a strong pulse signal, is inputted, and then, in step 2, it is determined whether the carriage 9 has moved a predetermined distance or not. As usual, the count of the pulse counter 15a is determined based on whether or not the content force (predetermined (direct G) has been reached. If not, the process returns to step (2), and when the gear 1/knob 9 reaches a predetermined distance, the process proceeds to step (2)G, where the rotation of the servo motor 11 is stopped.

Next, in step (2), the pulse counter 15a is reset, and then in step (2), the distance Xi between the distance detector 10 and the road surface at the current position of the carriage 9 is read from this distance detector 10 as road surface distance data, and this is It is temporarily stored in a predetermined storage area of the storage device 23.

Next, the process moves to step (2), and it is determined whether the carriage 9 has reached the right end. The determination in this case is made by determining whether the number of road surface distance data stored in the storage device 23 in step (2) has reached a predetermined value. Then, steps ■ to step ■ are repeated until the carriage 9 reaches the right end, and when the carriage 9 reaches the right end, the process moves to step ■, reads out the road surface distance data stored in the storage device 23 in step ■, and (The calculation of Equation 11 is performed to calculate the additional material amount S, and this is stored in a predetermined storage area of the storage device 23 as additional material amount calculation data.

Next, the process moves to step ■, and in step ■, the storage device 2 is
The additional material calculation data stored in 3 is read out and sent to the recording device 30 and display device 31 via the interface circuit 21. As a result, the recording device 3
The additional mixed material amount data is recorded in 0, and the additional mixed material amount data is digitally displayed on the display device 31.

When the microswitch 7 is off, the process returns to step [phase], and when the microswitch 17 is turned on, the process moves to step @.

In this step @, it is determined whether or not to end the road surface shape detection. The determination in this case is made by determining whether a road surface detection end switch (not shown) has been pressed. When the road surface detection end switch is not pressed down, the system moves to the steering knob [phase] to read the driving data. The running data in this case is read by reading the contents of the pulse counter 6a. Next, the process proceeds to step 0, where it is determined whether the vehicle has traveled a predetermined distance. The determination in this case is made by determining whether the count content of the pulse counter 6a read in step 7 step 0 has reached a predetermined value.

When the vehicle has not traveled a predetermined distance, it returns to step [phase], and when the predetermined distance is reached, it moves to step [phase], and while resetting the pulse counter 6a, it returns to step [phase].

In addition, the process in step (2) is performed using a specific example of the carriage movement end determination means 27 in step (2).
The processing in step 0 is a specific example of the resurfacing mixture amount calculating means 28, and the processing in steps 0 to [phase] is a specific example of the vehicle mileage determining means 24.
Specific examples are shown below.

Next, an embodiment in which the road surface shape detection device 1 according to the present invention is applied to a road surface resurfacing device will be described with reference to FIG. 5 and subsequent figures.

That is, the road surface resurfacing device 40 includes front wheels 42 on a vehicle body 41.
and a rear wheel Lj is attached, and the rear wheel 43 is rotated by a hydraulic drive morph (not shown) driven by a swash plate pump 46 driven by an engine 45 by operation from a driver's cab 44. Run.

A receiving hopper 47 for receiving compacting material (new asphalt paving material) from a new material transporting IM vehicle (not shown) such as a dump truck is provided at the front part of the vehicle body 41. The compacted material discharged from the new composite material supply mechanism 4
8 is conveyed diagonally upward by a first chain conveyor 49, and delivered onto a second chain conveyor 50.

This second chain conveyor 50 is connected to an expanded IF1. It is transported to a position corresponding to between the mechanism 67 and the leveling mechanism 70, and the new interest is dropped between them.

In each chain conveyor 49,50, as shown in FIG. 6, spreading plates 52 are bridged at a predetermined interval between endless chains 51L and 51R arranged in parallel at a required interval in the width direction of the vehicle body 41, The chain conveyor 49 has a bottom plate 53 that covers the lower part of the upper chain part, and the chain conveyor 50 has a bottom plate 54 that covers the lower part of the lower chain part. therefore,
The chain conveyor 49 has an upper chain portion and a bottom plate 53.
The embedding material is conveyed by the chain conveyor 50, and the embedding material is conveyed by the lower chain portion and the bottom plate 54. The chain conveyor 50 is provided with an opening/closing mechanism 55 at a position corresponding to a new material receiving port 65 of a stirring mechanism 61, which will be described later. The opening/closing mechanism 55 includes an opening 56 formed in the bottom plate 54 and extending in the width direction, an opening/closing plate 57 for opening/closing this opening 56, a fluid pressure cylinder for driving the opening/closing plate 57 to open/close, a piston rod thereof, and an opening/closing plate 57 for opening/closing the opening/closing plate 56. It is comprised of an opening/closing drive mechanism 58 that includes a rotating arm and the like connected to a plate 57. When the opening/closing plate 57 is in the open position where the opening 56 is opened, the embedding material conveyed by the chain conveyor 50 is dropped into the new material receiving port 65 of the stirring mechanism 61 through the discharge chute 59, and the opening/closing plate 57 is the opening 56
When the chain conveyor 50 is in the closed position, the compacting material conveyed by the chain conveyor 50 is dropped between the spreading mechanism 67 and the leveling mechanism 70. In this case, the chain conveyors 49 and 50 are driven by a drive command signal from the microcomputer 20, which will be described later, to deliver the required amount of compacting material to the stirring mechanism 61, or to the spreading mechanism 67 and the spreading mechanism 7.
Supply to 0.

Furthermore, a sowing comb mechanism 60 is disposed between the front wheels 42 and the rear wheels 43 of the vehicle body 41 at a position in contact with the road surface, which loosens the asphalt pavement honeymoon and collects or sows the loosened old company. At the same time, a stirring mechanism 61 is connected to the rear side thereof.

An example of the scraping mechanism 60 has front and rear scarifiers 62 and 63 that are rotatably supported by a frame 61, and the scarifier 62 has two screw conveyors arranged in opposite spiral directions in parallel in the road surface width direction. , these screw conveyors have a structure in which a bottle-shaped canter is protruded from the outer peripheral edge. Therefore, by rotating the scarifier 62 in the forward direction, the road surface is scattered and the scattered rustic shrines are collected in the center, and by rotating the scarifier 62 in the opposite direction, the road surface is being scattered and the scattered rust is collected. Materials can be drawn externally.

Furthermore, by rotating the screw conveyors in opposite directions, it is possible to adjust the amount of drawing and scraping. Furthermore, by changing the rotation speed of the screw conveyor, the amount of raking or scraping can be changed.

The scarifier 63 also has the same configuration as the scarifier 62, except that it is configured with a single screw conveyor whose spiral direction is reversed at the center.

The scarifiers 62 and 63 are driven in forward and reverse directions by drive command signals from the microcomputer 2o, which will be described later. Further, the frame 61 is suspended from the vehicle body 41 by a lifting mechanism 64, and is configured to be able to adjust the depth of scraping.

The stirring mechanism 61 takes in the polymer material scraped up by the scraping mechanism 60 and transports it backwards while stirring to drop it on the road surface, or supplies it to the new composite material receiving port 65 by the chain conveyor 50. The new composite material is stirred and mixed together with the polymerized material while being transported backwards and dropped onto the road surface.

The stirred mixture discharged from the stirring mechanism 61 is heated by a heater 66 disposed behind it, and then transferred to the diffusion mechanism 6.
7, it is averaged in the width direction of the road surface.

This diffusion mechanism 67 is composed of a screw conveyor 68 whose helical direction is changed in the center and a blade screed 69 disposed behind the screw conveyor 68. Averaged -1.

After that, the leveling mechanism 7 disposed on the rear side of the vehicle body 41
At 0, the composite material is not spread evenly. This leveling machine WL7
An example of 0 is a screed 72 that vibrates the road surface, which is rotatably attached to a rotary arm 71 that is pivotally connected to the vehicle body 41, and a screed 72 that is disposed in front of the screed 72 and conveyed by a chain conveyor 5o. A screw conveyor 73 that spreads the material in the width direction of the road surface.

A road surface shape detection device 1 is disposed between the front wheel 42 and the loosening mechanism 60. In this case, the microcomputer 2° of the road surface shape detection device 1 serves both as road surface detection and drive control of the new composite material supply mechanism 48 and the scraping mechanism 60 of the road surface resurfacing device 4o. For this reason, the microcomputer 20, as shown in FIG.
In addition to the road surface data storage means 26, the carriage movement end determination means 27, and the resurfacing mixture calculating means 28, a resurfacing mixture adjusting means 75 is added. The resurfacing mix material adjusting means 75 drives and controls at least one of the new mix material supply mechanism 48 and the spreading loosening mechanism 60 based on the calculation result of the resurfacing mix material amount calculation means 28, so that the mix material is The supply amount is adjusted and the road surface level at the time of resurfacing is set as the reference level.

Next, the effect will be explained. First, a case will be described in which the resurfacing method is a so-called remixing method in which the polymer material loosened by the spreading mechanism 60 is mixed with a new composite material and the mixed composite material is not spread evenly.

In this case, the opening/closing mechanism 55 is opened, and the new interest stored in the receiving presser 47 is conveyed to the upper center of the vehicle body 41 by the chain conveyor 49, and then dropped onto the chain conveyor 50, whereby the opening/closing mechanism 55 When it is fed 1υ to the position, the opening/closing mechanism 55 is released, so the new composite material falls downward and enters the new composite material receiving slot 65 of the stirring mechanism 61.
It will be put inside.

Further, the guide roller 5L of the road surface shape detection device I.

5R is brought into contact with a reference surface such as the L-shaped groove 33 and center line 34 position on the shoulder of the road.

In this state, first, a road surface heating vehicle (not shown) equipped with a heater is set as a leader, and the road surface resurfacing device 40 is driven to follow the vehicle. At this time, the distance between the two is set to such an extent that the asphalt pavement surface, which has been softened by the heating by the road surface heating force, will not harden.

When the road surface resurfacing device 40 starts running, as described above, the road surface shape is detected and the resurfacing material calculation means 28 calculates the additional material amount S. This calculated additional mixed material amount S
Based on this, the resurfacing mix material adjustment means 75 is driven, and, for example, the new mix material supply mechanism 48 is controlled so that its new mix material supply amount becomes the additional mix material amount S, and the spreading mechanism 6
The scarifiers 62 and 63 of No. 0 are lowered by the lifting mechanism 64 while being driven in normal rotation so as to scrape up the old mixed material in the center. This makes the scarifier 62.6
In step 3, the old mixed wood can be scraped together with scraps, and the old mixed wood that has been sown can be collected in the center.

In this way, the scraped old composite material is collected in the center by the scraping mechanism 60, so that the old composite material collected as the road resurfacing device 40 travels is collected by the stirring device 6.
It is accommodated within 1. On the other hand, the new company dropped from the opening 56 from the receiving pumper 47 via the chain conveyor 4.9.50 is supplied into the stirring mechanism 61, so this new company and the old mixed material that has been scattered are mixed. are stirred and mixed. In this case, the amount of the new and old mixed material is the sum of the old material used to loosen the road surface and the additional new material with the additional material amount S, which is the amount that is commensurate with maintaining the road surface at the standard level. Become.

Then, the stirred and mixed new and old mixed materials are transferred to the stirring mechanism 61.
The transport action causes the vehicle to fall onto the road behind it.

The mixed material that has fallen onto the road surface is reheated by the heater 66, then spread uniformly in the width direction of the road surface by the spreading device 67, and then spread evenly by the leveling mechanism 70 to make a flat surface. .

In addition, when resurfacing by the so-called repaving method in which new material is layered and spread over the old composite material that has been scraped, the opening/closing mechanism 55 provided on the chain conveyor 50 is first activated and the opening/closing plate 57 The opening 56 of the bottom plate 53 is closed. As a result, the new company stored in the receiving damper 47 is conveyed by the chain conveyor 49,50 and falls onto the road surface between the spreading mechanism 67 and the leveling mechanism 70.

In this way, the road surface resurfacing device 4
0 is run, the old mixed material is spread by the loosening mechanism 60, only this loosened old mixed material is stirred by the stirring mechanism 61, and then this stirred old mixed material is spread behind the stirring mechanism 61. It is discharged from the side onto the road surface. Then, the discharged stirring polymer material is uniformly spread in the width direction of the road surface by a spreading device 67.

The new company falling from the chain conveyor 50 is layered on top of this spread old composite material, so the layered new company is spread uniformly in the road surface width direction by the screw conveyor 73 of the leveling mechanism 70, and then The road is leveled with a screed 72 to create a flat road surface.

Here, the processing procedure when each of the above-mentioned means in the microcomputer 20 is realized by a program mainly based on a microprocessor is as shown in FIG. 8, and step (2) in FIG. The processing procedure is the same as that shown in FIG. 4, except that the drive control 48 is controlled in accordance with the additional amount S of mixed material calculated in step (2) to adjust the amount of new mixed material supplied. In this case, in step (2), the chain conveyor 49.50 is driven for a time corresponding to the required amount of mixed material (or the chain conveyor speed is controlled, or the gate height is controlled),
The new company is dropped to a position in front of the stirring mechanism 61 or the leveling mechanism 70.

Note that the road surface shape detection means 7 is not limited to the above-mentioned embodiment, but includes a carriage 9 that is movable downward.
A slider having an engagement roller provided at the lower end is disposed, and the slider is engaged with the road surface and moved up and down along the road surface shape,
The displacement of the moving element may be detected by a displacement detector such as a differential transformer or a detection coil to obtain an electrical detection signal, or any other distance measuring device may be used.

In this case, when the detection data of the road surface shape detection means 7 is an analog signal, it is connected to the microcomputer 20 via an A/D converter 80 as shown by the chain line in FIG.

Furthermore, in each of the above embodiments, a case has been described in which the road surface shape detection device 1 reads the road surface shape every time the road surface shape detection device 1 travels a predetermined distance. It is also possible to perform more accurate detection of the road surface shape by reading the information and taking into account the traveling speed of the road surface resurfacing device 40. Similarly, the greater the number of samplings performed by the distance detector 10, the more the road surface shape detection accuracy can be improved.

Furthermore, the road surface shape detection means 7 is not limited to the configuration of the above embodiment, but may include a plurality of distance detectors 10 disposed at predetermined intervals in the road surface width direction, and road surface distance data from these distance detectors 10. The data may be read in parallel or serially and stored in the storage device 23.

As explained above, according to the present invention, the present invention includes a truck movable in the longitudinal direction of the road surface, and a road surface shape detection means mounted on the truck and configured to scan the road surface in the width direction. The system was configured to obtain electrical detection data according to the road surface shape.

Therefore, it is possible to reliably understand the road surface shape based on the detected data, and it is also possible to easily calculate the amount of additional mixed material when resurfacing. It is possible to obtain the effect that it can be applied to control the amount of mixture material required when performing pavement.
