Description

[Technical field]

[0001] The present invention relates to a chipping device and a chipping method, and more particularly to a self-propelled chipping device that performs cleaning, chipping, grinding, and the like using a water jet, which is a high-pressure water jet, and a chipping method using the same. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there has been known a technique for cutting, crushing, and chipping paved road surfaces such as concrete and asphalt by jet injection of high-pressure water. As one method for carrying out such construction work, water jet chipping devices are widely used. Water jet chipping devices are configured to perform chipping work by driving a traveling device with a prime mover, for example, so that the device can travel on the road surface while spraying high-pressure water (for example, see Patent Document 1).

[0003] The maximum chipping width of the chipping device is equal to the maximum lateral width of the nozzle unit in the water jet device. For this reason, in conventional devices, it was necessary to make the width of the water jet device large in order to improve the efficiency of the chipping work. Furthermore, in conventional devices, the weight of the device usually exceeded 3,000 kg in order to stably perform the chipping work, taking into consideration the scattering of the destroyed objects and the reaction force caused by the injection of high-pressure water. In other words, conventional chipping devices were bulky and heavy in order to improve the work efficiency and perform the chipping work stably. [Prior art documents] [Patent documents]

[0005] However, the conventional chipping device as shown in Patent Document 1 could not maneuver efficiently when there were obstacles at the work site, and chipping work could not be performed efficiently.

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. The components of each embodiment described below can be appropriately combined. In addition, some components may not be used.

[0013] (Chipping equipment) The configuration of the chipping device of this embodiment will be described with reference to FIGS. As shown in Fig. 1 to Fig. 4, the chipping device 100 includes a traveling device 10, a water jet device 20, and a platform 30. The water jet device 20 is supported on the front side of the traveling device 10 via a connector 40, and sprays high-pressure water toward the object to be chipped. The platform 30 is provided on the rear side of the traveling device 10, and functions as an installation stand and a counterweight.

[0014] <Running gear> The traveling device 10 is equipped with an engine as a power source, and drives a hydraulic pump to perform traveling drive. The traveling device 10 has a rotating body 11 and a traveling body 12 . The rotating body 11 supports the water jet device 20 via a connecting body 40. The running body 12 supports the rotating body 11.

[0015] The rotating body 11 has a boarding space 13 where an operator boards, and a machinery room 14 located below the boarding space. The boarding space 13 has a pilot's seat 15 where the operator sits, and a control section 16. The machinery room 14 houses a hydraulic oil tank, a hydraulic pump, an engine that generates power to drive the hydraulic pump, and a battery. The hydraulic pump is driven by the engine of the rotating body 11, and supplies hydraulic oil to each actuator including the hydraulic cylinder 41.

[0016] The control section 16 is provided with a control lever 17 for controlling the rotational movement of the revolving body 11, the vertical drive movement of the water jet device 20, the traveling movement of the traveling body 12, and the like. The control section 16 is configured so that an operator seated in the operator's seat 15 can operate the chipping device 100 by operating the above-mentioned control lever 17. The chipping device 100 of this embodiment can be automatically operated by a control panel 35 described later, but can also be manually operated by the control lever 17. This allows the traveling device 10 to travel even when the control panel 35 is not in operation.

[0017] In this specification, the term "automatic operation" refers to a form in which some of the various operation actions required for chipping by an operator are automated. "Automatic operation" means that the operation can be performed without the need for operator operation.

[0018] In addition, the battery stored in the machine room 14 can supply power to the control panel 35 when power is not supplied from the commercial power source to the control panel 35. This allows the chipping device 100 to not only travel the traveling device 10 in an environment without a commercial power source, but also to perform chipping work.

[0019] The rotating body 11 rotates by the power generated by a hydraulic motor. The hydraulic motor is driven by hydraulic oil supplied from a hydraulic pump, and generates power for rotating the rotating body 11 in the horizontal direction.

[0020] The running body 12 has a pair of tracks. The chipping device 100 travels by rotation of the tracks. The running body 12 may have wheels.

[0021] <<Concatenation>> The connector 40 is a member that connects the revolving body 11 and the water jet device 20. The connector 40 and the revolving body 11 are removably connected using pins or bolts. For example, the connector 40 and the revolving body 11 may be connected using eight pins or bolts. Note that the number of pins or bolts that connect the connector 40 and the revolving body 11 may be other than eight, such as two, and the size of the pins or bolts may also be determined according to the shape and weight of the device.

[0022] The connector 40 and the water jet apparatus 20 are removably connected using pins or bolts. For example, the connector 40 and the water jet apparatus 20 may be connected using eight pins or bolts. The number of pins or bolts connecting the connector 40 and the water jet apparatus 20 may be other than eight, such as two, and the size of the pins or bolts may be determined according to the shape and weight of the apparatus.

[0023] FIG. 5 is an explanatory diagram for explaining a state in which the water jet device is detached from the traveling device in the chipping device according to the embodiment of the present invention. By removing the pins or bolts, an operator can easily separate the heavy and bulky water jet device 20 from the revolving body 11, as shown in Fig. 5. This allows the chipping device 100 to be made smaller and lighter, and it can be more easily carried in and out of narrow spaces, etc.

[0024] A hydraulic cylinder 41 is attached to the connecting body 40. The hydraulic cylinder 41 is driven by hydraulic oil to drive the water jet device 20 up and down toward the object to be chipped.

[0025] The chipping device 100 of this embodiment does not include an arm and a boom that are usually provided in conventional chipping devices. The chipping device 100 includes the above-mentioned hydraulic cylinder 41 instead of the arm and the boom. This allows the water jet device 20 to move up and down while achieving a reduction in size and weight of the chipping device 100. Furthermore, the size of the connecting body 40 to which the hydraulic cylinder 41 is attached in the traveling direction of the chipping device 100 (the length direction of the chipping device 100 in a side view) is smaller than the length of a general arm and boom. The upper limit of the size of the connecting body 40 in the traveling direction is not particularly limited, but from the viewpoint of miniaturization, it is preferably 1.2 m or less, more preferably 1.1 m or less, and even more preferably 1.0 m or less. The lower limit of the size of the connecting body 40 in the traveling direction is not particularly limited, but is usually 0.35 m or more. Therefore, the chipping device 100 of this embodiment has a smaller relative distance between the water jet device 20, which is a heavy object, and the revolving body 11 compared to the conventional chipping device. This makes it possible to prevent the center of gravity of the chipping apparatus 100 from being located forward, thereby reducing the weight of the counterweight required for the chipping apparatus 100. Therefore, the chipping apparatus 100 can be made smaller and lighter.

[0026] The shape of the connector 40 is not particularly limited, and may be any shape that can connect the water jet device 20 and the rotating body 11. The connector is not particularly limited, and may be configured, for example, to have a pair of columns and a plurality of connector support frames stretched across them, with the base end of the hydraulic cylinder 41 attached to a lower connector support frame fixed to the pair of columns, and the tip end of the hydraulic cylinder 41 attached to an upper connector support frame that supports the water jet device so that it can slide relative to the columns. The water jet device supported by the upper connector support frame can be moved up and down by the extension and contraction drive of the hydraulic cylinder 41. The members that make up the connector are not particularly limited, and are preferably made of iron plates or the like from the viewpoint of durability.

[0027] <Water jet device> The water jet device 20 is a device that ejects high-pressure water to chip an object to be chipped, such as concrete. The water jet device 20 may be a conventionally known device. The water jet device 20 has a nozzle unit 21, a support frame 22, a traverse rail 23, a traverse motor 24, a reverse limit switch 25, and a splash protection bucket 26.

[0028] The nozzle unit 21 has a nozzle, a swivel that converts the water flow into rotational motion, and a gearbox that reduces the rotation of the rotary motor and increases the torque. High-pressure water can be sprayed (rotated) by supplying water to the nozzle via the swivel. In addition, the rotation speed and torque can be adjusted by changing the gear ratio of the gearbox. There are no particular limitations on the type of nozzle as long as it is a nozzle that can be used for chipping work by the water jet method. Examples of types of nozzle include a single nozzle, a collision type double nozzle, and a non-collision type double nozzle.

[0029] The traverse rail 23 is supported by a support frame 22. The nozzle unit 21 is configured to be reciprocally movable horizontally along the traverse rail 23 by a traverse motor 24. The reversing limit switch 25 is a member for setting the chipping width at any position. The nozzle unit 21, which reciprocates horizontally along the traverse rail 23, stops at the position of the reversing limit switch 25 and moves in the opposite direction. In other words, the reversing limit switch 25 determines the turning back position of the nozzle unit 21. Therefore, by adjusting the reversing limit switch 25 to any position, the horizontal chipping width can be freely adjusted. Therefore, the water jet device 20 can chip a desired range without being limited by the fixed range of the traverse rail 23.

[0030] The splash protection bucket 26 has a peripheral wall and a cover. The bottom surface of the splash protection bucket is open. A water stop made of rubber or the like is attached to the lower end of the peripheral wall. By bringing the lower end of the splash protection bucket 26 into close contact with the object to be chipped, such as concrete, an enclosed space can be created between the cover and the object to be chipped. This makes it possible to prevent high-pressure water sprayed against the object to be chipped from scattering around. From the viewpoint of soundproofing, the splash protection basket 26 is preferably made of a highly soundproof steel plate or the like.

[0031] <Platform> The platform 30 is provided on the rear side of the traveling device 10 and functions as a mounting base and a counterweight. The counterweight refers to a weight used to adjust the center of gravity of the chipping device 100 to the rear when the water jet device 20 is installed, which causes the center of gravity of the chipping device 100 to shift forward, resulting in poor balance of the entire device.

[0032] In the chipping device 100 of this embodiment, the platform 30 is provided on the rear side of the traveling device 10, so that the center of gravity of the entire chipping device 100 can be shifted rearward. This improves the stability of the entire chipping device 100 and reduces the weight of the weight of the weight separately installed as a counterweight, thereby achieving a reduction in size and weight of the chipping device 100.

[0033] Here, when performing maintenance on the chipping device 100, it is necessary to open the door of the machine room 14 of the rotating body 11 to the rear and inspect the equipment inside the machine room 14. However, in the chipping device 100 of this embodiment, the platform 30 is provided on the rear side of the machine room 14 to function as a counterweight. For this reason, there was a problem that the control panel 35 supported by the platform 30 got in the way and it was difficult to secure sufficient space for an operator to perform maintenance.

[0034] In order to solve the above problem, the platform 30 of this embodiment is configured to have a fixed part 31 fixed to the traveling device 10, and a movable part 32 connected to one end of the fixed part 31 in the width direction so as to be freely rotatable within a horizontal plane.

[0035] FIG. 6 is an explanatory diagram for explaining a state in which the movable part of the platform is fixed by a fixing device in the chipping device according to the embodiment of the present invention. FIG. 7 is an explanatory diagram for explaining a state in which the fixing device is removed and the movable part is rotated in the chipping device according to the embodiment of the present invention. The platform 30 has a removable fixture 33 that fixes the movable part 32 to the other end in the width direction of the fixed part 31 and restricts the movable part 32 from rotating in a horizontal plane around one end of the fixed part 31 as an axis. The fixture 33 may be, for example, a pin. By removing the fixture 33, the movable part 32 can be opened and closed by rotating about 0 to about 120 degrees with respect to the back surface of the traveling device 10, thereby ensuring a sufficient space for an operator to inspect the devices in the machine room 14. The rotatable angle of the movable part 32 may be any angle other than about 0 to about 120 degrees, such as about -10 to about 180 degrees with respect to the back surface of the traveling device 10.

[0036] The movable part 32 supports a hydraulic control part 34 that controls the supply of hydraulic oil and a control panel 35 that controls the operation of the chipping device 100 . The hydraulic control unit 34 and the control panel 35, together with the fixed unit 31 and the movable unit 32, also function as a counterweight. The fixed part 31 may carry a separate counterweight 50 if required.

[0037] The shapes of the fixed part 31 and the movable part 32 are not particularly limited and can be designed appropriately. The fixed part 31 is not particularly limited, but may be formed, for example, in an L-shape when viewed from the side. By forming it in an L-shape, it is possible to secure a sufficient space for installing devices and the like. The movable part 32 may be, for example, in the shape of a rotatable door as described above.

[0038] The chipping device 100 effectively utilizes the dead space defined by the fixed part 31 and the movable part 32 of the platform 30. By arranging modular valves, hydraulic hoses, electric wiring, air regulators 60, etc. in this dead space, it is possible to secure sufficient installation space for the device above the chipping device 100 without being restricted in layout in relation to the revolving body 11 (for example, without the need to change the layout of the revolving body 11 or restricting the storage position of the chipping device 100, etc.). This achieves the miniaturization of the chipping device 100.

[0039] <<Hydraulic control unit>> The hydraulic control unit 34 has a modular valve in which a solenoid valve, a relief valve, and a throttle valve are integrated, and a directional control valve. The modular valve controls the flow rate of hydraulic oil supplied from the hydraulic pump to each actuator for operating the fishing gear 100. The directional control valve switches and controls the flow of hydraulic pressure. During automatic operation of the chipping device 100, the modular valves and directional control valves of the hydraulic control unit 34 may exclusively supply hydraulic oil to the traveling of the traveling device 10. During manual operation of the chipping device 100, hydraulic oil may be supplied to each actuator via each valve by the control lever 17 without going through the hydraulic control unit 34. <<Control panel>> FIG. 8 is a block diagram showing an example of the configuration of a control panel according to an embodiment of the present invention. The control panel 35 controls the travel and operation of the chipping device 100. The control panel 35 has an operation unit 36 ​​, a monitor 37 , a voltage step-up / step-down unit 38 , and a control unit 39 .

[0040] The operation unit 36 ​​receives control commands for the rotation, swing, traverse, and reverse motion of the nozzle unit 21 in the water jet device 20, and the travel of the traveling device 10. The monitor 37 displays an input screen corresponding to the settings selected by the operator and the contents of the input item selection buttons. The operation unit 36 ​​and the monitor 37 are preferably touch panels. The step-up / step-down unit 38 steps up or steps down AC power supplied from a commercial power source or the like. The step-up / step-down unit 38 can also step up or steps down DC power supplied from a battery or the like. The control unit 39 takes in signals from various sensors and encoders provided in the chipping device 100, performs a predetermined calculation, and controls the operation of the driving members provided in the chipping device 100 based on the calculation results and the received signals.

[0041] The chipping device 100 can be driven by a commercial power source (100V) because the engine drives the hydraulic pressure required for the chipping device 100. The control panel 35 has the above-mentioned step-up / step-down unit and supplies a voltage suitable for various voltages for driving the chipping device 100. For example, the traverse motor 24 of the water jet device 20 is boosted from 100V to 200V by the step-up / step-down unit 38 of the control panel 35, and then the boosted voltage is output to drive the traverse motor 24. The reverse limit switch 25 of the water jet device 20 is driven by a commercial power source (100V). Furthermore, the control panel 35 boosts the 12V supply power from the battery to 100V by the step-up / step-down unit 38, and can use it as a drive power source. This allows the chipping device 100 to operate the traveling device 10 and perform chipping work even in an environment where no power is being supplied to an external AC power source. In addition, since conventional chipping devices require a 200V or 400V AC power source, they cannot use commercial power sources and the traveling device 10 cannot travel in an environment without electricity.

[0042] The size of the chipping device 100 is not particularly limited, but the size in the direction of travel of the chipping device 100 (the length direction of the chipping device 100 when viewed from the side) is approximately 2.5 m to 3.5 m, the size in the width direction is approximately 1.0 m to 3.0 m, and the size in the height direction is approximately 1.0 m to 2.0 m. If the size of the chipping device 100 is within the above range, it can be easily carried in and out of narrow spaces, etc. Also, because it is maneuverable, chipping work can be efficiently performed even at work sites with obstacles, etc.

[0043] As described above, in the chipping device 100 of this embodiment, the water jet device 20 can be easily detached from the connecting body 40. The lower limit of the widthwise size of the water jet device 20 alone is usually 1.0 m or more. From the viewpoint of sufficiently increasing the chipping width and improving the chipping work efficiency, the lower limit of the widthwise size of the water jet device 20 alone is preferably 2.0 m or more, more preferably 2.2 m or more, and even more preferably 2.5 m or more. From the viewpoint of miniaturization and weight reduction, the upper limit of the widthwise size of the water jet device 20 alone is preferably 3.0 m or less. Moreover, the widthwise size of the traveling device alone is usually about 0.6 m to 1.5 m.

[0044] The maximum chipping width of the chipping device 100 is preferably 2000 mm or more, so that the chipping work can be carried out efficiently. In this specification, the maximum chipping width refers to the maximum width that can be chipped toward the chipping target without moving the chipping device 100 in the width direction. As described above, the maximum chipping width is equal to the maximum lateral width of the nozzle unit 21 of the water jet device 20. The chipping device of this embodiment 100 has been made smaller and lighter overall, but the water jet device 20 can be the same as that of a conventional large chipping device. Therefore, the chipping device of this embodiment 100 can have a maximum chipping width similar to that of a conventional large chipping device. The upper limit of the maximum chipping width is not particularly limited, but is usually 3000 mm or less.

[0045] The weight of the chipping device 100 is preferably 3000 kg or less. If the weight of the device is 3000 kg or less, it can be mounted on a small on-board truck crane with a loading platform of 3000 kg, and can be efficiently transported to and from the work site. The upper limit of the weight of the chipping device 100 is not particularly limited, but is usually 4000 kg or less.

[0046] (Chipping method) Hereinafter, a construction example of a chipping operation using the chipping device of this embodiment will be described with reference to Fig. 9. Fig. 9 is a flowchart of a chipping method according to this embodiment.

[0047] First, in order to transport the chipping device 100 to the work site, the pins or bolts of the connecting body 40 are removed, and the water jet device 20 is removed from the connecting body 40 (ST01: step of removing the water jet device). This achieves further weight and size reduction of the chipping device 100, reduces the cost of transporting it to the work site, and allows the chipping device 100 to be transported to the work site quickly. Furthermore, even if the work site is in a narrow area, the chipping device can be easily brought in and taken out because of its small size.

[0048] As described above, the weight of the chipping device 100 of this embodiment is usually 3000 kg or less. Therefore, the chipping device 100 of this embodiment can be mounted on a small-sized on-board truck crane with a loading capacity of 3000 kg even without removing the water jet device 20 from the connecting body 40. Therefore, the step ST01 may be performed as necessary.

[0049] Following the implementation of ST01, the water jet device 20 and the chipping device 100 detached from the connecting body 40 are transported to the chipping work site (ST02: step of transporting to the work site). As described above, the devices are loaded onto a small-sized on-board truck crane with a loading capacity of 3000 kg and can be transported to the work site.

[0050] Following the implementation of ST02, at the chipping work site, the water jet device 20 is connected to the chipping device connector 40 using a pin or bolt (ST03: Step of connecting the water jet device)

[0051] Following the implementation of ST03, the chipping work is performed on the object to be chipped (ST04: chipping work step). Specifically, prior to chipping work, an operator sets and inputs the operating conditions and the like of the chipping device 100 from an operation unit 36 ​​of a control panel 35 attached to the platform 30 of the chipping device 100. In this embodiment, it is preferable that the operation unit 36 ​​and the monitor 37 are touch panels, and that the touch panel screen displays an input screen corresponding to the settings selected by the operator and the contents of the input item selection buttons, and that numerical values ​​and the like are directly input by touching the input positions of each input screen.

[0052] The input operation conditions are not particularly limited, but for example, the operation date and time, the traveling speed of the traveling device 10, the maximum traverse width, traverse speed, pitch distance, etc. of the nozzle unit 21 are set as basic settings. Next, the specifications of each nozzle unit 21, the combination settings, the number of revolutions, the inclination angle, etc. are input. In addition, the stop time when the nozzle unit 21 is located at the end is set so that over-digging does not occur when the nozzle unit 21 turns around at the edge of the chipping target area, and the lower limit of water pressure drop is set so that there are no areas that are insufficiently chipped due to a drop in water pressure. As for the traveling conditions, automatic traveling and manual traveling can be switched according to the work conditions. By appropriately selecting the traveling speed and the nozzle shape, the chipping depth, the reinforcing bar position, the reinforcing bar density, etc. in the chipping target area can be appropriately set.

[0053] After inputting the operating conditions, the chipping operation is automatically performed according to the inputted set values. As described above, the chipping device 100 of this embodiment can be manually operated using the control lever 17. The rotating operation of the rotating body 11, the vertical drive operation of the water jet device 20, the traveling operation of the traveling body 12, etc. may be manually operated using the control lever 17.
