Description

[Technical Field]

[0001] The present invention relates to a cutting control device for cutting a paved road surface. [Background technology]

[0002] Conventionally, asphalt-paved roads include not only expressways and ordinary roads on which ordinary automobiles travel, but also circuits for automobile races and test courses for automobile performance testing. Circuits and test courses not only have flat tracks, but also have banks (slope) that slope toward the inside of the curves where cars travel at high speeds.

[0003] On roads, repair work is sometimes carried out to repair the paved road surface so that automobiles can travel smoothly, and a cutting rotor equipped with cutting bits of a road surface cutting device is rotated along the direction of the road to cut the paved road surface flatly and then repave it. Conventionally, the road surface cutting device disclosed in Patent Document 1 is known as a road surface cutting machine that cuts an already paved asphalt mixture layer.

[0004] The road surface milling device in Patent Document 1 is equipped with a cutting unit for milling the road surface on a mobile body, and mills the road surface with the cutting unit while the mobile body is moving. A road surface unevenness detection mechanism is provided in front of the milling unit to automatically detect unevenness in the road surface to be milled by the cutting unit, and a cutting unit control mechanism is provided to control the milling unit in accordance with the road surface unevenness detected by the road surface unevenness detection mechanism 4 and automatically adjust the milling depth formed by the cutting unit 3. The cutting unit is composed of a rotatable shaft body provided in a direction perpendicular to the traveling direction of the mobile body, and a plurality of cutting bodies fitted and fixed to this shaft at predetermined intervals in the direction perpendicular to the traveling direction of the mobile body.

[0005] However, cutting control devices used to cut paved road surfaces do not have a belt conveyor for transporting the cutting waste. For example, when cutting the asphalt pavement of a bank of a road, the cutting waste is not transported by a belt conveyor, so the cutting waste remains next to the cutting machine, on the downhill side of the driving lane being cut.

[0006] Measurement points are set at predetermined distances along the direction of travel on the road, and it is necessary to cut to different depths depending on the position of each measurement point. Therefore, the cutting depth for each driving lane is usually marked at each measurement point on the road surface.

[0007] However, the road milling device in Patent Document 1 is also not equipped with a belt conveyor for removing cutting waste, so on a bank, for example, cutting waste remains next to the milling machine, on the downslope side of the driving lane being milled, making it impossible to see the cutting depth at the next measurement point. This requires an operator to remove the cutting waste immediately next to the road milling machine, recheck the cutting depth data, and re-mark it, which not only makes it difficult to work but also results in positional deviations.

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-183261 Summary of the Invention [Problem to be solved by the invention]

[0009] In view of the above, the present invention relates to a cutting control device for cutting paved road surfaces, and aims to provide a cutting control device that can cut easily and to an accurate depth without the need for pre-marking to indicate the cutting depth, checking the cutting depth data, or re-marking after removing the cutting waste material. [Means for solving the problem]

[0010] According to an embodiment of the present invention, there is provided a milling control device for milling a paved road surface, comprising: The track has measurement points at predetermined distances along the direction of travel, The vehicle is characterized by comprising a vehicle body, a running mechanism provided on the vehicle body to run the vehicle body, an odometer provided on the running mechanism to measure the distance traveled, a road surface cutting device provided on the vehicle body to cut the road surface of the track to an adjustable depth, and a monitor that displays the measurement point according to the distance from a reference position measured by the odometer and the cutting depth at the measurement point.

[0011] According to this configuration, the cutting control device includes a driving mechanism for driving the vehicle body, an odometer for measuring the distance traveled, a road cutting device for cutting the paved road surface to an adjustable depth, and a monitor. The monitor displays the measurement points and the cutting depth at each measurement point according to the distance from a reference position measured by the odometer. For example, when cutting asphalt pavement on a banked road, even if cutting waste remains next to the cutting machine on the downslope side of the driving lane being cut, obscuring the markings indicating the cutting depth for each driving lane at each measurement point on the road, the monitor can be used to check the cutting depth at each measurement point. This eliminates the need for advance marking of the cutting depth, confirmation of cutting depth data, and re-marking after removing the cutting waste, allowing the paved road surface to be easily cut to an accurate depth.

[0012] Preferably, the monitor displays the distance of the measurement point from a reference position and the number of the travel lane to be cut.

[0013] With this configuration, the distance from the reference position of the measurement point and the number of the travel lane to be cut are displayed on the monitor, making it easier to understand the current position and preparing to change the cutting depth at the next measurement point, improving workability. This makes it possible to easily cut the paved road surface to the correct depth.

[0014] Preferably, the monitor displays the measurement point during cutting and the cutting depth at the measurement point, and at least the next and subsequent measurement points and the cutting depth at the next and subsequent measurement points.

[0015] With this configuration, the monitor displays the measurement point currently being cut, the cutting depth at that measurement point, and at least the next measurement point and the cutting depth at the next measurement point and the measurement points thereafter, so it is possible to know in advance that the cutting depth will change at the next measurement point. This allows preparation to be made to respond to the change in cutting depth at the next measurement point, making it possible to easily cut the paved road surface to the correct depth.

[0016] Preferably, a control unit is provided that automatically adjusts the cutting depth of the road surface cutting device to a cutting depth that corresponds to the predetermined measurement point.

[0017] With this configuration, the cutting control device is equipped with a control unit that automatically adjusts the cutting depth of the road surface cutting device to the cutting depth corresponding to the predetermined measurement point, so that changes in cutting depth can be reliably accommodated without manually operating the cutting depth. This makes it possible to easily cut the paved road surface to the correct depth.

[0018] Preferably, the odometer is capable of correcting the distance measured at the position of the measurement point.

[0019] With this configuration, the odometer can correct the distance measured at the measurement point, so even if there is a discrepancy between the measurement value by the odometer and the actual position of the measurement point, the distance can be corrected for each measurement point, making it possible to easily cut the paved road surface to an accurate depth. [Effects of the Invention]

[0020] Regarding a cutting control device for cutting paved road surfaces, it is possible to provide a cutting control device that can cut easily and to an accurate depth, eliminating the need for advance marking to indicate the cutting depth, confirmation of cutting depth data, and re-marking after removing cutting waste.

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings, which conceptually (schematically) show a construction machine including a cutting control device. [Example]

[0023] The paved road surface to be cut by the cutting control device 10 will be described using the bank 51 of the road 50 as an example. As shown in Figure 1(A), track 50 is a test course for automobiles, and is composed of straight sections and curved sections in plan view. The straight sections are composed of horizontal surfaces, and the curved sections are composed of banks (slope) 51. Bank 51 starts with a gentle slope that connects to the straight section, becomes steep in the middle of the curve, and then becomes a gentle slope that connects to the straight section again, with a horizontal top edge 52 about 4 m wide at the top end and a horizontal or slightly sloped shoulder 53 several meters wide at the bottom end.

[0024] Measurement points are provided on the track 50 at predetermined intervals along the direction of travel. For example, measurement points are provided in the following order from the entrance of the bank 51 where the track 50 transitions from a straight section to a curved section: P1, P2, P3, ..., Pn. The bank 51 is formed so that the radius of curvature changes depending on the position of the measurement points, resulting in a gradual change in the curved shape. Note that the cutting depth cut by the cutting control device 10 moving along the travel lanes 51a and 51b varies depending on the construction location based on the position of the measurement points and the travel lanes 51a and 51b of the bank 51. Note that the cutting by the cutting control device 10 is performed for each of the travel lanes 51a and 51b.

[0025] As shown in Figure 1(B), the bank 51 at measurement point P2 (line BB), just after entering the curved section from the straight section, has a gentle slope overall, with the slope angle ∠B1 near the shoulder 53, the slope angle ∠B2 midway in the height direction, and the slope angle ∠B3 near the top 52 all being approximately the same angle of the bank 51 from the low position to the high position.

[0026] As shown in Figure 1(C), the bank 51 at measurement point P4 (CC line), a little further into the curve, has a slightly larger overall slope, with the slope angle ∠C1 near the shoulder 53, the slope angle ∠C2 midway along the height direction, and the slope angle ∠C3 near the top 52 gradually increasing as the bank 51 approaches from a low position to a high position.

[0027] As shown in Figure 1(D), the bank 51 at measurement point P6 (line DD) in the middle of the curve has an increased overall slope, with the slope angle ∠D1 near the shoulder 53, the slope angle ∠D2 midway in the height direction, and the slope angle ∠D3 near the top edge 52 increasing as the bank 51 approaches from a low position to a high position, reaching a maximum of approximately 45 degrees. Furthermore, the radius is r1 at positions lower than the middle in the height direction, and the radius is r2 at positions higher than the middle in the height direction, so even at the same measurement point P6, the radius differs across the width of the road 50 (traveling lanes 51a, 51b).

[0028] Furthermore, at the same height in the vertical direction, in other words, in the same lane in the driving direction (at the same distance from the end of the track 50), whether at a low position, a middle position, or a high position, the angle of the bank 51 increases as you move from the entrance of the curve (line BB) to the middle of the curve, and the angle of the bank 51 decreases as you move closer to the exit at the bottom.

[0029] Next, a method for paving the bank 51 using various construction machines will be described. As shown in Figures 2(A) and 2(B), a dump truck 70 that carries asphalt mixture 60 and an asphalt stacker 71 that supplies the asphalt mixture 60 received from the dump truck 70 to a slope asphalt finisher (construction machinery) 10 are placed on the shoulder 53 at the lower end of the bank 51. A belt conveyor 75 is provided on the asphalt stacker 71, and this belt conveyor 75 supplies the asphalt mixture 60 to the hopper 14 of the slope asphalt finisher 10.

[0030] Located midway up the height of the bank 51 is a slope asphalt finisher 10 that spreads and levels the asphalt mixture 60, and a slope roller (construction machinery) 30 that compacts the spread and leveled asphalt mixture 60 behind the slope asphalt finisher 10.

[0031] Arranged on the top 52 of the bank 51 are a construction machinery supporter (finisher supporter) 40 that runs alongside the slope asphalt finisher 10 while suspending it by a wire rope 46, and a construction machinery supporter (roller supporter) 40 that runs alongside the slope roller 30 while suspending it by a wire rope 46. The construction machinery supporter (finisher supporter) 40 and the construction machinery supporter (roller supporter) 40 run alongside the slope asphalt finisher 10 and the slope roller 30 while adjusting the tension of the respective wire ropes 46 so that the slope asphalt finisher 10 and the slope roller 30 move at the same constant height.

[0032] In the process of spreading and leveling the asphalt mixture 60, the main devices used are an asphalt stacker 71 that travels along the shoulder of the bank 51 and supplies the asphalt mixture 60, and an asphalt finisher 10 for slopes that travels along the bank 51 and spreads and levels the supplied asphalt mixture 60.

[0033] Next, the slope asphalt finisher 10 will be described. The slope asphalt finisher 10 comprises a tractor 11 as the main body, running wheels (crawlers) 12 attached to the tractor 11, a driver's seat for an operator to drive and perform various operations, a hopper 14 attached to the tractor 11 into which heated asphalt mixture 60 made by mixing asphalt with aggregate such as crushed stone or sand is supplied (put in) from an asphalt stacker 71, and a bar feeder that transports the supplied asphalt mixture 60 to the rear of the vehicle.

[0034] The slope asphalt finisher 10 also includes a screw 16 that is mounted behind the tractor 11 and spreads the asphalt mixture 60 evenly across the paving width, a tamper that is mounted behind the screw 16 and compacts the asphalt mixture 60, a leveling arm that is mounted on the tractor 11 in an angle-adjustable manner and extends rearward, a screed mechanism 20 that is mounted on the leveling arm and spreads the compacted asphalt mixture 60 evenly, and a pulley 24 that receives the wire rope 46.

[0035] The screed mechanism 20 is supported by the tractor 11 and is a mechanism that spreads and levels the asphalt mixture 60 and can change the leveling width by expanding and contracting in the vehicle width direction. It is equipped with a screed that directly spreads and levels the asphalt mixture 60 that has been compacted by a tamper, and a step that is provided behind the screed and on which the operator can stand.

[0036] Next, the construction machine supporter 40 will be described. The construction machinery supporter 40 comprises a vehicle body 41, a crawler 42 for traveling mounted on the vehicle body 41, a driver's seat for an operator to drive and perform various operations, a counterweight positioned on the opposite side to where tension is applied to the wire rope 46 for balancing, and a winch 45 mounted on the vehicle body 41 for winding up the wire rope 46.

[0037] Next, the asphalt stacker 71 will be described. The asphalt stacker 71 comprises a vehicle body 72, a running mechanism (crawlers, wheels) 73 mounted on the vehicle body 72 to run the vehicle body 72, a driver's seat for an operator to drive and perform various operations, a stacker hopper 74 mounted on the vehicle body 72 to which the asphalt mixture 60 is supplied (loaded) from the dump truck 70, a belt conveyor 75 mounted on the vehicle body 72 with its angle and direction adjustable to transport and supply the asphalt mixture 60, and an angle direction adjustment mechanism mounted on the vehicle body 72 to adjust the angle and direction of the belt conveyor 75.

[0038] Next, a method for cutting asphalt pavement using the cutting control device 80 of the embodiment will be described. As shown in Figures 3 and 4, repair work is sometimes carried out on the asphalt pavement of roadway 50 to ensure smooth vehicle travel. A cutting rotor 85 equipped with a cutting bit from a cutting control device 80 is rotated along the roadway to cut the asphalt pavement flat, and then the pavement is resurfaced. The following describes the bank 51 of roadway 50 as an example. For bank 51, which was paved using the paving method described above, the cutting control device 80 is used to cut the asphalt pavement for each of the travel lanes 51a and 51b of bank 51. Cutting of bank 51 is performed by a construction machine supporter (crane) 90 traveling alongside the shoulder 53 of bank 51, suspending the cutting control device 80, which cuts bank 51, via a wire rope 96.

[0039] The construction machinery supporter (crane) 90 comprises a vehicle body 91, wheels 92 for running attached to the vehicle body 91, a driver's seat 93 for an operator to drive and perform various operations, an arm 94 attached to the vehicle body 91 that is extendable and angle-adjustable, and a winch 95 attached to the arm 94 that winds up a wire rope 96.

[0040] Next, the cutting control device 80 will be described. As shown in FIGS. 3 to 5, the cutting control device 80 cuts the asphalt pavement of the bank 51 that is paved with asphalt.

[0041] The cutting control device 80 comprises a vehicle body 81, an operating unit 82 provided at the rear of the vehicle body 81 and enabling the operator to perform various operations, a traveling mechanism 83 provided on the vehicle body 81 and causing the vehicle body 81 to travel, an odometer (not shown) provided on the traveling mechanism 83 and measuring the distance traveled, a road surface cutting device 84 provided on the vehicle body 81 and cutting the road surface of the bank 51 to a variable depth (depth can be changed in the left and right directions), a control unit 86 provided on the vehicle body 81 and controlling the operation of the traveling mechanism 83, the road surface cutting device 84, etc., a monitor 87 that displays the measurement point according to the distance from a reference position measured by the odometer and the cutting depth at measurement points P1, P2, and P3, and a pulley 88 to which a wire rope 96 is connected.

[0042] Next, the state of the bank 51 when it is cut will be described. As shown in Figure 4(A), measurement points P1, P2, and P3 are provided on bank 51 at predetermined distances along the direction of travel, and since it is necessary to cut to a predetermined depth depending on the position of each measurement point, markings 55 indicating the cutting depth, etc. for each driving lane 54a, 54b are usually placed on the road surface of bank 51 at each measurement point position P1, P2, and P3.

[0043] To cut the asphalt pavement of the bank 51, a cutting control device 80 is used that is not equipped with a belt conveyor for carrying out cutting waste material 61. When cutting the asphalt pavement of the travel lane 54b, which is located at a higher position on the bank 51, cutting waste material 61 remains in the travel lane 54a (next to the cutting control device 80), which is on the downslope side of the travel lane 54b being cut.

[0044] As a result, as shown in Figure 4(B), the markings 55 indicating the cutting depth at measurement points P1 and P2 are not visible in the lower traveling lane 54a. Therefore, in the conventional technology, an operator had to remove the cutting waste 61 immediately next to the cutting machine, recheck the cutting depth data, and re-mark the data. Furthermore, if the lower traveling lane 54a is cut first and then the higher traveling lane 54b is cut, the markings 55 for the higher traveling lane 54b remain. However, the cutting waste 61 discharged from the higher traveling lane 54b covers the cut surface of the lower traveling lane 54a, making it difficult to remove the cutting waste 61 from the cut surface. Therefore, cutting is not performed from the lower traveling lane 54a, but from the higher traveling lane 54b.

[0045] Next, the cutting control device 80 will be described again. Even when the cutting order of the travel lanes 54a and 54b is as described above, the cutting control device 80 according to the embodiment of the present invention is equipped with a monitor 87, etc., so that pre-marking 55 indicating the cutting depth, confirmation of cutting depth data, and re-marking after removing cutting waste material 61 are not required, and cutting can be performed easily and at an accurate depth.

[0046] 5 and 6, the monitor 87 displays the travel status 87a (e.g., in progress or stopped), the number (crossing position number) 87b of the travel lane 54a, 54b, ..., 54n being cut, the measurement point number 87d indicating measurement points P1, P2, ..., Pn including those currently being cut, the distance 87e of measurement points P1, P2, ..., Pn (measurement point number 87d) from the reference position, the cutting depth at measurement points P1, P2, ..., Pn (left depth 87c, right depth 87f), the actual cutting depth 87g, and the shift amount 87h. Furthermore, the monitor 87 displays the measurement point numbers 87d indicating at least the next and subsequent measurement points P1, P2, ..., Pn, and the cutting depth at the next and subsequent measurement points P1, P2, ..., Pn (left depth 87c, right depth 87f).

[0047] The control unit 86 automatically adjusts the cutting depth of the road surface cutting device 84 to a cutting depth corresponding to the predetermined measurement points P1, P2, ..., Pn. The odometer can correct the distance measured at the positions of the measurement points P1, P2, ..., Pn.

[0048] Next, the effects of the cutting control device 80 of the embodiment described above will be described. In this embodiment of the present invention, the cutting control device 80 includes a traveling mechanism 83 for driving the vehicle body 81, an odometer for measuring the distance traveled, a road surface cutting device 84 for cutting the road surface of the bank 51 to a variable depth (the depth can be changed in the left and right directions), and a monitor 87. The monitor 87 displays measurement points P1, P2, ..., Pn (87d) corresponding to the distance 87e from a reference position measured by the odometer, and cutting depths 87c, 87f at measurement points P1, P2, ..., Pn. Therefore, even if cutting waste material 61 remains next to the cutting machine on the downslope side of the driving lanes 54a, 54b being cut as the asphalt pavement of the bank 51, making it impossible to see the markings 55 indicating the cutting depth for each of the driving lanes 54a, 54b at each measurement point P1, P2, ..., Pn of the bank 51, the monitor 87 allows the operator to check the cutting depths 87c, 87f at each measurement point P1, P2, ..., Pn. As a result, the cutting control device 80 of the present invention eliminates the need for pre-marking 55 indicating the cutting depth, confirmation of cutting depth data, and re-marking 55 after removing cutting waste, and can easily cut paved road surfaces (for example, the surface of an asphalt-paved bank 51) to an accurate depth.

[0049] Furthermore, the monitor 87 displays the distance 87e from the reference position of measurement points P1, P2, ..., Pn and the number of the travel lane 54a, 54b to be cut, making it easier to understand the current position and allowing preparation for changes to the cutting depth 87c, 87f at the next measurement point P1, P2, ..., Pn, improving workability. This makes it possible to cut the paved road surface easily and to the correct depth.

[0050] Furthermore, the monitor 87 displays the measurement points P1, P2, ..., Pn (87d) currently being cut and the cutting depths 87c, 87f at measurement points P1, P2, ..., Pn, as well as the cutting depths 87c, 87f at at least the next and subsequent measurement points and the next and subsequent measurement points P1, P2, ..., Pn, so it is possible to know in advance that the cutting depths 87c, 87f will change at the next measurement points P1, P2, ..., Pn. This allows preparations to be made to accommodate changes to the cutting depths 87c, 87f at the next measurement points P1, P2, ..., Pn, making it possible to easily cut the paved road surface to the correct depth.

[0051] Furthermore, the cutting control device 80 is equipped with a control unit 86, which automatically adjusts the cutting depth of the road surface cutting device to a cutting depth corresponding to predetermined measurement points P1, P2, ... Pn, so that changes in cutting depths 87c, 87f can be reliably accommodated without manually operating cutting depths 87c, 87f. This makes it possible to easily cut the paved road surface to the accurate depths 87c, 87f.

[0052] Furthermore, since the odometer can correct the distance measured at the positions of measurement points P1, P2, ..., Pn, even if there is a discrepancy between the measurement value by the odometer and the actual position of the measurement point, the distance 87e (overprogression, underprogression) can be corrected for each measurement point P1, P2, ..., Pn, making it possible to easily cut the paved road surface to an accurate depth.

[0053] In the embodiment, the control unit 86 controls the road surface cutting device 84 to automatically adjust the cutting depth, but this is not limited to this, and the operator may manually adjust the cutting depth while watching the monitor 87.

[0054] In addition, in the embodiment, the monitor 87 displays information such as the traverse position number 87b currently being cut and the next and subsequent traverse position numbers 87b, but it may also display information such as the third and subsequent traverse position numbers 87b, or information such as the traverse position numbers 87b of traverse positions that have already been cut.

[0055] In addition, in the embodiment, the runway 50 is described as being a bank 51, but this is not limited to this, and the runway 50 may be a horizontal flat area, and for example, the measurement points may be at 10m intervals, and the operator may operate while looking at the monitor 87 so that the cutting depth gradually becomes from 40mm to 50mm as the cutting control device 80 moves forward 10m (the cutting depth gradually becomes 1mm deeper for every 1m that the cutting control device 80 moves forward).

[0056] In addition, in the embodiment, the application location of the cutting control device 80 has been described as the bank 51 of an asphalt-paved runway 50, but this is not limited to this, and the cutting control device 80 may also be applied to a flat runway or a paved road surface (including concrete pavement) on a large site.

[0057] That is, the present invention is not limited to the examples as long as the functions and effects of the present invention are exhibited. [Industrial Applicability]
