Description

  The present invention relates to a vehicle for treating a surface of a structure, such as cleaning of a road surface, cleaning of a side wall such as a tunnel / soundproof wall, cleaning of a white line applied to a road, or erasing of the white line. It relates to a surface-treated vehicle that can run on public roads.

  In recent years, there have been increasing cases of road surface cleaning work, side wall cleaning work such as tunnels and soundproof walls, white line applied to roads, or white line erasing work. The white line means, for example, a paved road lane line, a line for vehicle guidance and guidance, and the like. The white line is often formed by, for example, applying a wear-resistant paint on a paved road surface by heating.

  For example, in a road surface cleaning work, dust accumulated on the surface of a paved road is cleaned with high-pressure water, and polluted water is collected by a blower. Thereby, for example, drainage can be improved. In addition, when cleaning the side walls of tunnels, soundproof walls, etc., dirt on the side walls is removed with high-pressure water, and the polluted water is collected by a blower. Thereby, for example, aged deterioration can be prevented. In addition, the white line is darkened or worn by tires or the like when used for a long period of time, and it may be difficult for a vehicle driver to identify the vehicle and may cause a traffic accident. Therefore, in the white line cleaning work, the road and / or the white line is washed with high-pressure water, and the washed polluted water is collected by a blower. As a result, the white line can be kept white. In addition, when the white line is worn out or when it is necessary to change the lane, the white line is deleted to erase the existing white line and reapply the white line. High pressure water is sprayed on the surface, and the white line is peeled off and erased, and the peeled white line and the polluted water are collected by a blower. As a result, the existing white line is erased, and a new white line can be reapplied after erasure. In such surface treatment work, a surface treatment vehicle equipped with a device capable of jetting high-pressure water and collecting polluted water is used. The surface-treated vehicle must be able to drive on public roads to the construction site.

  For example, there are vehicles described in Patent Documents 1 and 2 as surface-treated vehicles that can generate high-pressure water, absorb polluted water, and can travel on public roads. A vehicle described in Patent Document 3 exists as a device for removing rubber adhering to the road surface of an airport runway, although it cannot self-propelled on a public road.

JP-A-10-82026 Japanese Patent No. 3687752 JP-A-6-264422 Paragraphs 0017/0019 / FIGS. 3 and 4

  In the vehicles of Patent Documents 1 and 2, a dedicated diesel engine is used as a power source for driving the high-pressure pump, the blower, and the air compressor. Therefore, the surface-treated vehicle must be equipped with a high-pressure pump, a blower, an air compressor, and a dedicated diesel engine, and in addition, various actuators, a control device, a cover, and the like must be added. Therefore, the overall dimensions and weight including the truck increase. Therefore, in order to load these devices and travel on public roads, large vehicles must be used, special vehicle inspection acquisition is required, and costs such as purchase and maintenance costs increase. Therefore, the driver also needs to have a driver's license for large vehicles.

  In the vehicle of Patent Document 3, the power of the high-pressure pump and the blower is extracted from the transmission unit (70) of the diesel engine (68) of the traveling vehicle by the power extraction shaft (72). However, the vehicle of patent document 3 is a vehicle for exclusive use of an air runway, and cannot drive itself on a public road. Furthermore, in the vehicle of Patent Document 3, a high-pressure pump or the like is driven even during self-running, and gasoline is consumed wastefully.

  Therefore, a surface treatment vehicle including a high pressure pump for generating high pressure water, a blower for sucking contaminated water, and a compressor for sending wind to collect the polluted water, the surface treatment vehicle is disposed on a public road. It is an object of the present invention to provide a vehicle that is capable of running on its own and is smaller than a large vehicle (for example, a medium-sized vehicle having a total vehicle weight of less than 11 tons).

  In order to solve the above problems, the present invention has the following features. The present invention is a surface-treated vehicle that can be self-propelled by an engine for traveling on a public road, and generates a negative pressure by a water tank, a high-pressure pump for generating high-pressure water from water stored in the water tank, and the like. The blower and the negative pressure generated in the blower suck the polluted water obtained by surface treatment with high-pressure water, and the polluted air in the polluted water tank is sucked by the negative pressure of the blower, It has a built-in water tank that removes dust, a compressor that supplies air for sucking polluted water, and a power take-off that takes out the power of the engine. , Blower and compressor.

  Preferably, a first clutch for power take-off is further provided, the first clutch is coupled at the time of surface treatment, and the first clutch is decoupled during traveling.

  Preferably, it further includes a cylinder for opening and closing the polluted water tank and a hydraulic pump for driving the cylinder, and the power extracted by power take-off may be supplied to the hydraulic pump.

  Preferably, the first transmission mechanism that supplies the power extracted by the power take-off to the blower, and the first transmission mechanism that supplies the power extracted by the power take-off to the high-pressure pump and / or the compressor. The second transmission mechanism and a second clutch provided between the first transmission mechanism and the second transmission mechanism may be provided.

  Preferably, the second clutch is coupled after the operation of the blower is stabilized.

  According to the present invention, since the power extracted by the power take-off is supplied to the high-pressure pump, blower, and compressor, the conventional high-pressure pump, blower, and compressor are driven. It is not necessary to install a special engine that is necessary separately. In addition, since the power take-off takes power from the engine for running on public roads, the surface-treated vehicle of the present invention can run on public roads. Therefore, since a high-pressure pump, a blower, and a compressor can be mounted on a vehicle smaller than a large vehicle (for example, a medium-sized vehicle having a total vehicle weight of less than 11 tons), a surface-treated vehicle smaller than a large vehicle can be provided.

  Also, by providing the first clutch for power take-off, the high-pressure pump, blower, and compressor are operated only during surface treatment, and when driving on a public road, only the wheels are driven, Since the blower and the compressor can be prevented from operating, public road self-running and surface treatment can be realized without consuming unnecessary gasoline.

  In addition, by supplying the power obtained by power take-off to the hydraulic pump for opening and closing the polluted water tank, no separate power is required to drive the hydraulic pump, and the surface treatment vehicle can be downsized. It will be further planned.

  Further, by providing the second clutch, the high-pressure pump and / or the compressor can be driven after the operation of the blower is stabilized.

  These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

(First embodiment)
FIG. 1 is a block diagram showing a functional configuration of a surface-treated vehicle 1 according to the first embodiment of the present invention. FIG. 2 is a diagram showing a structure around a power take-off (hereinafter referred to as PTO) 6 installed in the main body of the surface-treated vehicle 1. 1 and 2, a surface-treated vehicle 1 includes a high jet cleaner 2, a truck chassis 3, an engine 4, a mission 5, a PTO 6, a first clutch 6a for PTO, a traveling transmission 7, , Bearing 8, V pulley 9, V pulley 10, bearings 11, 11, hydraulic pump 12, universal joint 13, V pulley 14, V pulley 15, V belt 16, V belt 17 , Second clutch 18, blower 19, V pulley 20, V belt 21, V pulley 22, compressor 23, air tank 24, catcher 25, dirty water tank 26, and pressure regulator unit 27. A high pressure pump 28, a water tank 29, a cylinder 30, a polluted water suction pipe 31, a washing water ejection pipe 32, a blower 33, and a rear wheel 34. .

  The truck chassis 3 is a truck chassis for vehicles smaller than large vehicles, for example, medium-sized automobiles having a gross vehicle weight of less than 11 tons.

  In the first embodiment, the structure of the surface treatment vehicle 1 for treating the surface of the road surface (for example, cleaning of the road surface, washing of the white line, erasing of the white line, etc.) is shown. However, since the present invention is a surface-treated vehicle that can be self-propelled to the site in order to treat the surfaces of the side walls and other structures, it can be applied to other than the surface treatment of the road surface as shown in FIG. The When the present invention is applied in addition to the surface treatment of the road surface, it is sufficient that the high jet cleaner 2 has a structure adapted to the side wall and other structures. The structure of the high jet cleaner 2 is well known. Therefore, detailed description is omitted.

  When the surface treatment is performed, the first clutch 6 a is coupled, and the power obtained by the engine 4 is transmitted to the PTO 6 via the mission 5. During travel, the coupling of the first clutch 6a is released. In addition, the coupling | bonding and cancellation | release of the 1st clutch 6a at the time of construction and driving | running | working are arbitrary, and do not limit this invention. In addition to the power transmission mechanism to the PTO 6, the power of the engine 4 is configured to be transmitted to the traveling transmission 7 via the mission 5. Any known configuration can be used as a configuration for extracting the power of the engine 4 to the PTO 6, and the configuration is not limited to the configuration shown in the present embodiment. There is also a traveling clutch, but the illustration is omitted here. The power transmitted to the traveling transmission 7 is transmitted to the rear wheels 34, thereby enabling traveling.

  A universal joint 13 for transmitting power to the V pulleys 9 and 10 and the hydraulic pump 12 is coupled to the PTO 6. When the rotating shaft of the PTO 6 rotates, the universal joint 13 also rotates, the V pulleys 9 and 10 also rotate, and power is supplied to the hydraulic pump 12 together. In order to support the rotation of the universal joint 13, the bearings 8, 11, and 11 are provided. However, the structure of the bearings 8, 11, and 11 is not particularly limited in the present invention.

  The rotation of the V pulley 9 is transmitted to the V pulley 14 via the V belt 16. The rotation of the V pulley 10 is transmitted to the V pulley 15 via the V belt 17. The rotation shaft of the V pulley 14 is coupled to the second clutch 18. The rotation shaft of the V pulley 15 is coupled to the blower 19. The blower 19 has a structure capable of generating a negative pressure by power transmitted from the rotation shaft of the V pulley 15. The structure of the blower 19 is well known and will not be described in detail. Any known structure can be used as the structure of the blower 19. For example, a Roots blower can be used as the blower 19. The second clutch 18 is a mechanical element for controlling whether the power transmitted from the rotating shaft of the V pulley 14 is transmitted to the V pulley 20 or stopped. The second clutch 18 is engaged after the operation of the blower 19 is stabilized. This is because when the blower 19 is initially moved, the operation of the blower 19 is unstable and suction of the polluted water cannot be realized stably. First, after the blower 19 operates stably and the polluted water can be sucked, This is because the high-pressure pump 28 and the compressor 23 are operated to spray high-pressure washing water. The coupling of the second clutch 18 may be performed manually by the operator of the surface treatment vehicle 1 or after the stable operation of the blower 19 is confirmed by a control unit (not shown), the second clutch 18 is automatically engaged. You may make it combine. For example, an electromagnetic clutch can be used as the second clutch 18, but is not limited thereto.

  When the second clutch 18 is engaged, power is supplied to the rotary shaft of the high-pressure pump 28. The high-pressure pump 28 has a structure capable of sucking the water in the water tank 29 by the power supplied to the rotating shaft and turning it into high-pressure water. Since the structure of such a high-pressure pump 28 is well known, detailed description thereof is omitted here.

  When the second clutch 18 is coupled, power is supplied to the rotating shaft of the compressor 23 via the V belt 21 and the V pulley 22 connected to the V pulley 20. The compressor 23 has a structure capable of compressing air and supplying the compressed air to the air tank 24 by the power supplied to the rotating shaft. Since the structure of the compressor 23 is well known, detailed description thereof is omitted here.

  As described above, the power extracted from the engine 4 by the PTO 6 is supplied to the blower 19, the high-pressure pump 28, and the compressor 23. In the above, power is transmitted to the blower 19, the high pressure pump 28, and the compressor 23 using the V pulleys 9, 10, 14, 15, 20, 22, the V belts 16, 17, 21, and the universal joint 13. However, the power transmission mechanism is not limited to these. As long as a transmission mechanism for transmitting the power extracted by the PTO 6 to the blower 25, the high-pressure pump 28, and the compressor 23 is provided, the power transmission mechanism is not limited to these.

  Further, in consideration of the case where the second clutch 18 is provided, the surface treatment vehicle 1 includes at least a first transmission mechanism that supplies the power extracted by the PTO 6 to the blower 19 and a high-pressure pump that extracts the power extracted by the PTO 6. 20 and / or the 2nd transmission mechanism supplied to the compressor 23 should just be provided. In this case, the second clutch 18 only needs to be provided between the first transmission mechanism and the second transmission mechanism.

  The polluted water suction pipe 31 and the polluted water tank 26 communicate with each other. In order to prevent the backflow of the polluted water, the polluted water suction pipe 31 communicates above the polluted water tank 26, but the present invention is not limited to this. The polluted water tank 26 and the catcher 25 are connected by a pipe for sending the polluted air in the polluted water tank 26 to the catcher 25. The catcher 25 and the blower 19 are connected to each other by a pipe for sending clean air from which dust is removed by the catcher 25 to the blower 19. When the blower 19 generates a negative pressure, the polluted water suction pipe 31 sucks the polluted water. The polluted water sucked by the polluted water suction pipe 31 is stored in the polluted water tank 26. At this time, the contaminated water tank 26 contains contaminated air containing dust and the like. Contaminated air is sent to the catcher 25 by the negative pressure of the blower 19. Water is contained in the catcher 25, and the catcher 25 is a water-containing tank. The contaminated air is introduced into the water built in the catcher 25. Thereby, the dust in the polluted air settles in the water, and the washed air is taken out. The cleaned air is supplied to the blower 19 by the negative pressure of the blower 19 and exhausted from the blower 19.

  The water tank 29 and the high-pressure pump 28 are connected with each other by a pipe. The high-pressure pump 28 and the pressure adjustment unit 27 are communicated with each other by a pipe. The pressure adjustment unit 27 and the washing water ejection pipe 32 are in communication. The water tank 29 stores clean water. The water in the water tank 29 is supplied to the high pressure pump 28. The high pressure pump 28 applies pressure to the supplied water to form high pressure water. The high pressure water is supplied to the pressure adjustment unit 27. The pressure adjustment unit 27 adjusts the pressure of high-pressure water. In addition, since the structure of the pressure adjustment unit 27 is known, detailed description is abbreviate | omitted. The high-pressure water whose pressure has been adjusted by the pressure adjustment unit 27 is sent to the washing water jet pipe 32. From the washing water ejection pipe 32, high-pressure water is ejected and sprayed onto the surface such as the road surface. High-pressure water removes dirt from the road surface and white lines, and the white lines are peeled off. At this time, the high-pressure water and dirt or the white line after peeling are mixed with the high-pressure water to become polluted water. The polluted water is sucked by the polluted water suction pipe 31.

  The compressor 23 and the air tank 24 are connected by a pipe. The air tank 24 and the blower 33 are communicated with each other by a pipe. The air compressed by the compressor 23 is temporarily stored in the air tank 24. Compressed air is appropriately ejected from the air tank 24. The blower 33 supplies the compressed air from the air tank 24 to the polluted water suction pipe 31 and the washing water jet pipe 32. As a result, the air required for sucking the polluted water is supplied from the blower 33. The detailed configuration of the high jet cleaner 2 is not limited to the configuration illustrated in FIG. 1, and any known configuration can be used.

  The hydraulic pump 12 applies pressure to the hydraulic oil by the rotational force from the universal joint 13 and drives the cylinder 30 by the obtained hydraulic pressure. The cylinder 30 is used to open and close the open / close portion of the polluted water tank 26. When all the water in the water tank 29 is used for the surface treatment, the polluted water is stored in the polluted water tank 26. Polluted water is treated as industrial waste. After completion of the construction, the surface-treated vehicle 1 self-travels to the treatment site. In the treatment plant, the engine 4 is driven, the PTO 6 takes out power, the hydraulic pump 12 is driven, the cylinder 30 opens the polluted water tank 26 and discards the polluted water. After discarding the polluted water, the polluted water tank 26 is closed by the cylinder 30. It should be noted that the blower 19, the high-pressure pump 28, and the compressor 23 may be controlled so as not to operate during this disposal operation. In addition, since the mechanism other than the mechanism using the hydraulic pump 12 and the cylinder 30 may be employed for opening and closing the polluted water tank 26, the hydraulic pump 12 and the cylinder 30 are not essential in the present invention.

  Thus, in the first embodiment of the present invention, power extracted from the traveling engine by the PTO 6 is used as a power source for the high-pressure pump 28, the blower 19, and the compressor 23. Therefore, it is not necessary to mount a separate dedicated engine necessary for driving the high-pressure pump 28, the blower 19, and the compressor 23 as in the prior art. Therefore, since the high-pressure pump 28, the blower 19, and the compressor 23 can be mounted on a vehicle smaller than a large vehicle (for example, a medium-sized vehicle having a total vehicle weight of less than 11 tons), a surface-treated vehicle smaller than a large vehicle can be provided. It becomes.

  Further, by providing the first clutch 6a for the PTO 6, the high pressure pump 28, the blower 19 and the compressor 23 are operated only at the time of surface treatment, and only the rear wheel 34 is driven at the time of self-propelled driving on the public road. Since the pump 28, the blower 19, and the compressor 23 can be prevented from operating, public road self-running and surface treatment can be realized without consuming unnecessary gasoline.

  Further, by supplying the power obtained by the PTO 6 to the hydraulic pump 12 for opening and closing the polluted water tank 26, no additional power for driving the hydraulic pump 12 is required. Miniaturization will be further achieved.

  Further, by providing the second clutch 18, the high-pressure pump and / or the compressor 23 can be driven after the operation of the blower 19 is stabilized.
