Description

The present invention relates to an apparatus for cleaning a tire to which mud such as a construction vehicle is attached.

Generally, mud and earth and sand in the site are often attached to wheels such as dump trucks that enter and exit the civil engineering construction site, etc., and when entering the general road as it is, the earth and sand fall and scatter and soil the road, Frequent street cleaning is required. In addition, wet mud after raining will not only damage the landscape on the streets, but it will also rise to dust after drying, affecting the surrounding residents and developing into environmental problems. .

In order to prevent these problems, it is necessary to drop the muddy soil adhering to the tires and undercarriage before going out to the public road. The removal method is to wash the tires with a high pressure washer or install a water tank. A method such as washing away by passing through the tank or cleaning by forcibly injecting water into these water tanks using power separately is employed.

JP 2004-237913 A Japanese Patent No. 3248070

Among the above methods, the method using the high-pressure washing machine requires that work personnel be separately provided or the driver gets off to work, and when the number of carrying vehicles increases, the waiting time increases and the carrying efficiency deteriorates. In addition, the latter method of passing through the water tank has been commercialized as a tire cleaning water tank with various functions so far, but sufficient cleaning cannot be performed simply by passing through the water stored in the water tank. The method of using water to inject and wash water often drops, but on the other hand, temporary maintenance is required separately, pump failure, clogging of the nozzle, etc. Was needed.
The object of the present invention is to eliminate these drawbacks. The tire of the transport vehicle itself steps on one end of the cleaning function plate for the mud adhering to the tire that cannot be dropped simply by passing through the water tank. The present invention provides a tire cleaning device having a simple structure in which water is forcibly repelled for cleaning.

The present invention has the following configuration in order to solve the technical problems in the previous period.
As shown in FIGS. 1 and 2, a vehicle support rib perpendicular to the traveling direction of the vehicle 5 is provided in a water tank 1 having a width equal to or greater than the width of the vehicle, and the entrance is formed in a slope shape (2 and 4 in the figure). The intermediate portion is arranged at a predetermined interval so that the tire is slightly immersed in water. As shown in FIG. 4, the intermediate portion is centered on the bearing 11 provided at both ends of the vehicle support rib 8 or in the extending direction thereof. A handle handle function portion 3c having a function of drawing water is provided at an end portion of an arm 3a that rotates in a seesaw shape, and a tire handle step portion 3b provided at an end portion on the opposite side of the fulcrum causes the handle 7 to step down. 3c jumps up, and the water stored in this part is splashed and washed under the tires and the vehicle, and after passing, the handle function part sinks into the water, and the washing function plate 3 that can cope with washing of the next tire is continuously formed. Thailand characterized by the A cleaning apparatus.

The second aspect of the present invention is the cleaning function plate 3 in which the distance from the spindle pin 3d of the arm 3a to the handle function part 3c is longer than the distance from the tire stepping part 3b, and the center of gravity is biased.
As shown in FIGS. 10 to 17, the cleaning function plate 3 shown in FIG. 14 is provided with U-shaped bearings 11 b 1 at both ends of the vehicle support rib 8 or U-shaped bearings 11 b 2 in the extending direction thereof. Is rotated like a seesaw and can be easily detached from the top.
As shown in FIG. 18, when the one wheel 7 a of the 10-ton dump rear tire, which is often used for earth and sand transport, is located between the vehicle support ribs, The other wheel 7b is arranged so as to be positioned on the vehicle support rib. Specifically, when the rib is arranged on two-ninth or two-sevenths of the rear wheel biaxial length (wheel base), An effect is obtained.
As shown in FIGS. 20 and 21, the bottom portion of the water tank 1 has a curved concave shape with a deep central portion, and a gentle downward slope with respect to the vehicle traveling direction as shown in FIG. A reservoir 13 is provided.
In the sixth aspect, as shown in FIGS. 22 to 24, a water stirring plate 15 is provided below the cleaning function plate 3 via a stay 14.
As shown in FIG. 25, the water tank is divided into two parts with respect to the vehicle traveling direction, and the tank connecting metal fittings 16 are provided at the outer corners of both ends of the inner mating surface so as to be freely fitted.

First, compared to a tank that simply runs underwater, this device forcibly deposits mud and other deposits that could not be dropped until now, and the upper and lower sides when the tire passes between ribs. The synergistic effect with exercise can increase the cleaning effect.
Because these watering operations use the kinetic energy of the vehicle itself without the need for other power, other workers are unnecessary, and the dump driver does not need to get off such as turning on the machine operation switch. The washing process can be performed smoothly without stopping. Moreover, since it has a simple structure, there are few failures and repairs are easy.

The concrete effect of claim 2 is that the distance from the fulcrum of the cleaning function plate 3 to the handle function part 3c is longer than the distance from the tire stepping part 3b and the center of gravity is biased, so that the handle is not passed through the vehicle. When the functional part 3c is lowered and submerged, water is supplied to the handle part, and when the tire is stepped on, the operating speed of the handle part is doubled and water can be repelled vigorously. FIG. 4 shows the operating situation.
In addition, by rounding the cross-sectional shape of the tire stepping part, it is possible to prevent damage that can occur when the tire hits the corner of the tip as much as possible, and because the material can be diverted to general-purpose products such as round steel and deformed reinforcing bars, By increasing or decreasing the member diameter or changing the mounting position, it is possible to adjust the operation start time and the operating angle of the handle function part.
Claim 3 is provided with U-shaped bearings 11b1 at both ends of the vehicle support ribs or U-shaped bearings 11b2 in the extending direction so that the cleaning function plate 3 described in FIG. The plate itself can be easily exchanged, and if the plate is reversed left and right, the traveling direction of the vehicle can be easily changed. Specific mounting forms are shown in FIGS.
This is the arrangement interval of the vehicle support ribs 8 according to claim 4, which considers that the rear wheel biaxial tire interval of the 10-ton dump truck normally used for earth and sand transportation is approximately 1310 mm to 1350 mm. When the distance is calculated such that the rear wheel 7b is positioned at the apex of the rib when falling between the ribs, that is, the distance between the two wheels is not lowered, it is 2/9 (about 300 mm) or 2/11 of the rear wheel tire distance. By setting it to (about 240 mm), the engine is not burdened so much and vibration to the cargo bed can be reduced. If it is too wide, the engine load will be excessive to overcome, and if it is too narrow, the width of the handle function part will be limited, making it difficult to obtain the expected effect. (Fig. 18)

As shown in FIGS. 20 and 21, the bottom of the aquarium has a deep curved shape (12a, 12b) as shown in FIGS. 20 and 21, and has a downward slope in the same direction as the vehicle traveling direction as shown in FIG. By precipitating the earth and sand that has fallen due to the agitation of water into the front part of the water tank (the mud reservoir 13), the frequency of removing and cleaning the vehicle support ribs to remove the accumulated soil can be reduced, and maintenance is easy. It will be something.
Further, by adding the water stirring plate 15 of claim 6 below the cleaning function plate to the water tank having the bottom shape of claim 5, when the tire pushes down the stepping portion, the water stirring plate is forced in the water. Since this action is performed continuously from the front to the rear by moving the vehicle, it is possible to further prevent the sedimentation of underwater sediments and the like, and it is easy for the sedimentary soil to move to the forward mud reservoir 13. The soil removal work can be done more easily.

Although it is the effect of Claim 7, since the 10t dump truck is normally used for earth and sand conveyance, the thing of the minimum width of 2.5 m or more of a water tank is required. In order to transport this aquarium, of the vehicle restrictions based on the Road Law, the width is out of specification, and a special vehicle passage permission is required for transportation. Therefore, the water tank is divided into two parts in the vertical direction (vehicle traveling direction) and separated into layered layers during transportation, so that special vehicle passage permission is not required, and the size can be sufficiently transported even on a 4t truck. Also, as shown in FIG. 25, by providing the tank coupling 16 at both ends of the mating surface of the two-divided water tank so that they can be freely fitted, positioning can be performed easily, and the individual water tanks are integrated and more stable. .

First, in the construction site as close as possible to the entrance / exit, the water tank is buried in the ground according to the traveling direction of the vehicle to be withdrawn, or installed on the ground and the lifting slope 6 is attached back and forth so that the vehicle is inside the water tank. To make it passable. Next, the installation is completed if water is poured until the handle function part is submerged. (Fig. 25)
In this state, when the vehicle passes through the water tank, the tire pushes down the stepping portion downward, so that the water stored in the handle portion provided in the opposite direction of the fulcrum is continuously applied to the vehicle tire. And can be more effectively cleaned together with the vertical movement of the tire due to stepping in water. (Fig. 4)

Sediment that could not be dropped in a conventional tire wash tank that can only be passed through can be washed strongly by moving the vehicle itself without the need for a separate power facility, and the structure is simple, manufacturing costs are kept low, and maintenance is easy. Therefore, it seems that the availability is extremely high.
