Adopted.

According to the present invention, since the underbody can be washed while the traveling crawler is running idle, the traveling crawler is appropriately slackened to open the gap between the track shoes constituting the traveling crawler, and the jet is ejected. It is possible to make washing water that has entered into the gap deep. Then, by causing the traveling crawler to idle, the track shoes can delicately collide with each other to generate vibration. By these actions, the underbody can be effectively cleaned.

Further, the underbody cleaning apparatus for a crawler-type vehicle according to the present invention injects the washing water at a flow rate equal to or more than a predetermined amount, so that it is more effective than the case where high-pressure washing water is simply sprayed. Can be washed.

According to the present invention, in the above vehicle underbody cleaning apparatus, the cleaning liquid ejecting body is capable of cleaning by removing mud solidified and attached to the underbody of the crawler type vehicle from the surface thereof. The cleaning liquid is sprayed at a water pressure of.

Further, the vehicle underbody cleaning method is further characterized in that the washing water is sprayed at a predetermined water pressure at which the mud solidified and adhered to the underbody of the crawler-type vehicle is washed away from its surface. It is characterized by having been done.

Since the high-pressure jet easily cuts the solidified mud, the mud cut by the high-pressure jet forms a large mass. Such large lumps are clogged on the washing stand or the washing stand as they are without flowing, so that not only post-treatment becomes difficult, but also the smooth drainage of washing water is hindered.
On the other hand, in the present invention, the treatment is easy because the low-pressure jet causes the solidified mud to be separated from the surface and is flushed with a large amount of washing water.

According to the present invention, in the vehicle underbody washer, lifting means for lifting the crawler-type vehicle is provided at a height at which the traveling crawler can idle. Further, in the above-described vehicle underbody cleaning method, the crawler-type vehicle is lifted and supported to a position where the traveling crawler is released from contact with the ground.

According to the present invention, since the lifting means for lifting and lowering the vehicle to be cleaned is separately provided, the structure of a portion where the traveling crawler is grounded (for example, a cleaning stand) can be simplified. Therefore, an apparatus for performing post-treatment of the cleaning water used for cleaning can be easily installed.

According to the present invention, in the above vehicle underbody washing apparatus, the washing liquid ejecting body includes a plurality of cylinders extending vertically along the outside and inside of the traveling crawler. An injection port is formed, and these cylinders are provided so as to be rotatable within a predetermined range around the axis thereof.

According to the present invention, the underbody is reliably washed regardless of the length of the vehicle to be washed. In other words, in the case of a large vehicle, the overall length of the underbody is long, but by rotating the cylinder as the cleaning liquid ejecting body,
Inject the washing water to the end in the length direction of the undercarriage. For this reason, the cleaning liquid is evenly sprayed around the undercarriage, so that the cleaning residue can be prevented.

Further, according to the present invention, in the above vehicle underbody washing apparatus, a circulating section for circulating the washing water is provided,
The circulation section is provided with a filtration section for removing impurities contained in the used washing water.

In the cleaning apparatus according to the present invention, as described above, the flow rate of the cleaning water is not less than a predetermined amount. Therefore, if the washing water used for washing was discarded as it is,
It may lead to the quality of resources. In the present invention, the cleaning water used for cleaning is reused in order to effectively utilize resources. Therefore, the cost required for cleaning can be suppressed.

Vehicle undercarriage cleaning device 1 having the above configuration
According to this, the undercarriage of the tank 40 as a vehicle is cleaned as follows.

First, the tank 40 enters the washing section 2 by the operator, and the left and right traveling crawlers 42, 42 are mounted on the washing gantry 4, 4. At the time of approach, the operator causes the tank 40 to approach the washing unit 2 using the approach poles 24, 24 as a guide. At this time, when the traveling direction of the tank 40 is inclined and comes into contact with the vehicle guide rollers 23 # 23, a warning sound or the like is emitted, and the operator is prompted to correct the traveling direction. When the tank 40 enters the washing unit 2 and the rear part passes through the positions of the entry sensors 20, 20, it is determined that the tank 40 has entered an appropriate position.

After the tank 40 is mounted on the washing racks 4 and 4, the tank 40 is lifted to a predetermined height by the jack device 5. Depending on the type of vehicle to be washed, the height at which the traveling crawlers 42, 42 can be idled can be raised until the lower surfaces of the traveling crawlers 42, 42 are securely separated from the washing gantry 4, 4. Then, when the tank 40 is lifted and reaches a height at which the traveling crawlers 42, 42 can idle, the rotating lamp 25 is operated to notify the operator of the fact. Thereafter, while the traveling crawlers 42 and 42 of the tank 40 idle on the spot, the tank 4
Injection poles 10 and 11 and injection pipe 1
Cleaning is performed by injecting cleaning water from 2 and 12. The injection of the washing water is automatically started after the tank 40 is lifted, and is performed for a predetermined period of time.

FIGS. 4 and 5 show a tank 4 to be cleaned.
0 shows a state in which it is lifted. The tank 40 is provided at the center in the left-right direction, and the tank 4
The lower part of the main body frame 41 serving as a base of the jack cylinder 7, is supported by the contact portions 8, 8 of the jack cylinders 7, 7, and is lifted. As is apparent from these figures, the lower portions of the traveling crawlers 42 of the tank 40 are completely
Tank 40 has been lifted to a level away from the tank. Then, in the lifted state, the traveling crawlers 42, 42
While idling, a large amount of washing water is sprayed from the injection poles 10 and 11 and the injection pipe 12 toward the undercarriage for cleaning.

As described above, by lifting the tank 40, the traveling crawlers 42, 42 are slackened, and the track shoes 43 # 43 constituting the traveling crawlers 42, 42 are formed.
Even if the track shoes 43 are closely connected to each other, the gap formed between the track shoes 43 can be widened to some extent. Therefore, the washing water easily enters between the narrow gaps. And the traveling crawlers 42, 4
2 by rotating each of the track shoes 43 ‥ 4
In No. 3, a small collision repeatedly occurs with the adjacent track shoes 43 # 43 connected to each other. Gravel or clay stuck between the track shoes 43 of the traveling crawlers 42, 42 due to the vibration at this time, and the traveling crawlers 42, 42
Gravel, clay, and the like stuck between the traveling crawlers 42 and 42 and the idlers 45 ‥ 45 and the driving sprockets 46 for rotating the roller can be effectively washed away in a short time.

In the cleaning apparatus 1, the water pressure of the cleaning water is suppressed to some extent and a large amount of the cleaning water is sprayed so that the flow rate becomes a predetermined amount or more. It cleans gravel and clay. That is,
Since the high pressure jet easily cuts the solidified mud, the mud cut by the high pressure jet forms a large mass. The large lump does not flow and is clogged as it is on the washing stand or on the washing stand, making post-treatment difficult. In addition, it also hinders smooth drainage of washing water. On the other hand, the low-pressure jet makes the solidified mud exfoliate from the surface and is flushed with a large amount of washing water, thereby facilitating the treatment.

For example, in the case of mud of about 1 m ³ adhering to a crawler type vehicle having a total width of 3200 mm (crawler width of 550 mm) and a total length of about 6700 mm, the washing water to be sprayed has a pressure of 0.1 MPa to 0.2 MPa and a flow rate of 0.1 mPa. 200
is set to m ³ / h~400m ³ / h, it is possible to terminate the cleaning underbody at about 8 minutes.

When the washing is completed, the jack cylinder 7,
7, the cylinder rods 7a, 7a are lowered, and the traveling crawlers 42, 42 of the tank 40 are again grounded on the washing gantry 4, 4. Then, when the tank 40 is completely lowered, the operation of the rotating light 25 is stopped to notify the operator that the tank 40 can be advanced (FIG. 1).
reference). After that, the tank 40 is advanced by the operator and exits the washing unit 2. Also at this time, the operator advances the tank 40 while checking the exit poles 26, 26 in the traveling direction of the tank 40. When the traveling direction of the tank 40 is inclined and the outside contacts the vehicle guide rollers 23 # 23, a warning sound or the like is issued so as to urge the operator to correct the traveling direction.

The washing water used for washing as described above is subjected to filtration of the gravel and clay contained therein by the circulating section 3 provided in the present washing apparatus 1 to regenerate the washing water containing no impurities. Used again for cleaning.

First, the washing water used for washing flows from the washing gantry 4, 4 into the transport sections 32, 32 of the first filtration section 31. The transporting sections 32, 32 have a space portion in such a manner as to be flush with the direction in which the cleaning racks 4, 4 extend in order to pour a large amount of cleaning water used for cleaning. Conveyors 34, 34 for transporting gravel, mud, and the like contained in the washing water forward together with the washing water are arranged. In front of the conveyors 34, 34, a separation chamber 33 for separating relatively large gravel and the like from the washing water is provided. Conveyors 34, 34 are provided at the bottom of the separation chamber 33.
Conveyor 3 extending in the left-right direction so as to be orthogonal to
5 is provided downstream of the relay tank 33 a for diverting the flowing water from the weir of the separation chamber 33 to the mud sedimentation tank 36.
Is provided.

Gravel and mud carried out from the conveyors 34 and 34 are received by the discharge conveyor 35 and discharged out of the main cleaning apparatus 1. On the other hand, the washing water containing the small-sized mud and the oil component flows down from the separation room 33 to the relay tank 33a as it is, and is introduced into the mud sedimentation tank 36 as the second filtration unit.

The washing water is supplied to the mud sedimentation tank 3 serving as the second filtration unit.
When introduced into 6, the mud having a small particle size contained therein is settled at the bottom of the sedimentation tank, and is generated in washing water containing no mud. In the mud sedimentation tank 36, a polymer coagulant is sprayed on the washing water to separate and settle the mud efficiently at high speed. The mud that has settled to the bottom is returned to the separation chamber 33 by the discharge pump 36a.

The washing water filtered in the mud sedimentation tank 36 serving as the second filtration unit is introduced into an oil-water separation tank 37 serving as a third filtration unit disposed behind the mud sedimentation tank 36. Various oils are contained in the washing water used for washing. Not only the oil contained in the mud itself attached to the undercarriage due to the running of the tank 40 but also the tank 40 itself such as grease supplied to the sliding parts such as the drain of the running motor and the rotating shaft of the idler. The outgoing oil is contained in the washing water. In this oil separation tank, these oils are separated from the washing liquid.

The washing water from which the oil has been removed in this way is introduced into a water supply tank 38 disposed behind the oil / water separation tank 37, and is used again for washing the underbody.

The apparatus using the jack cylinders 7, 7 as the elevating means has been described above. However, the elevating means is not necessarily limited to the jack cylinders 7, 7, and for example, the supporting member may be formed of a body frame of a vehicle. Alternatively, the support may be attached to a hook of a crane device such as a portal crane, and the entire vehicle may be lifted and lowered by lifting the vehicle. In the case of using a crane device, for example, if the underbody cleaning device for a crawler type vehicle according to the present invention is installed at a place where an existing portal crane is installed, it is not necessary to provide a special elevating means. .

Further, the structure for raising and lowering the vehicle at the time of washing is not limited. For example, as shown in FIG. 6, the tank 40 itself as a vehicle is not moved up and down, the main body frame 41 of the tank 40 is supported on the support base 51, and the washing mounts 60, 6
0 may be raised and lowered. In the device shown in FIG.
Grooves 52 at positions corresponding to the traveling crawlers 42
52 are formed, and jack cylinders 53, 53 for raising and lowering the cleaning racks 60, 60 are installed in the grooves 52, 52, respectively. Jack cylinders 53, 53
It is preferable to provide at least at positions corresponding to the front part and the rear part of the tank 40 so as to sufficiently bear the weight of the tank 40.
In addition, injection poles 10 and 11 for injecting the washing water around the undercarriage of the tank 40 are provided on both side edges of the grooves 52 and 52, respectively. The injection poles 10 and 11 may be provided in the same manner as in the case of the cleaning device 1 shown in FIG. A support base 51 for supporting the main body frame 41 of the tank 40 is provided between the grooves 52. In the support base 51, when the tank 40 enters the washing section, the support base 51 is formed slightly lower so that the upper end of the support base 51 does not interfere with the lower surface of the tank 40. The support body 54 is configured to protrude from the support base 51. As described above, even when the cleaning frames 60 are raised and lowered without raising and lowering the vehicle itself, the cleaning water can be sprayed around the undercarriage while the traveling crawlers 42 and 42 run idle to perform cleaning.

The above-described underbody washing apparatus for crawler-type vehicles can effectively wash not only underbody of tanks but also underbody of crawler-type vehicles such as bulldozers, hydraulic shovels, pile drivers, and crawler cranes. it can. Among them, tanks, such as tanks and wetland bulldozers, are particularly effective for tanks equipped with a traveling crawler in which the distance between track shoes constituting a traveling crawler is narrow and the track shoes are closely connected to each other. . Needless to say, this does not hinder the use of the crawler-type vehicle underbody washing apparatus according to the present invention to wash the underbody of a wheel-type vehicle such as a wheel loader.

[0049]

As described above, according to the present invention, regardless of the type of traveling crawler mounted, the underbody of the crawler-type vehicle can be reliably washed in a short time. That is, in order to lift and wash the vehicle, the traveling crawler is appropriately slackened to open the gap between the track shoes constituting the traveling crawler, and the injected washing water is allowed to enter deep into the gap. Can be. Then, by causing the traveling crawler to idle, the track shoes can delicately collide with each other to generate vibration. By these actions, the underbody can be effectively cleaned.

Further, the underbody cleaning apparatus for a crawler-type vehicle according to the present invention sprays the cleaning water at a flow rate equal to or more than a predetermined amount, so that it is more effective than simply spraying high-pressure cleaning water. Can be washed. That is, since the high-pressure jet easily cuts the solidified mud, the mud cut by the high-pressure jet forms a large lump. Such large lumps are clogged on the washing stand or the washing stand as they are without flowing, so that not only post-treatment becomes difficult, but also the smooth drainage of washing water is hindered. On the other hand, the low-pressure jet makes the solidified mud exfoliate from the surface and is flushed with a large amount of washing water, thereby facilitating the treatment.

Since the washing water used for washing is not discarded, but is filtered and reused for washing, it is possible to realize a washing apparatus which can save resources and does not adversely affect the environment. it can.
