BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gap closing member for a weighing scale of a vehicle, which is arranged with respect to the weighing scale of the vehicle.

On expressways and the like, large vehicles that illegally exceed their weight are a factor in hastening the deterioration of roads. Therefore, on expressways, in order to prevent damage to the expressway and danger to traffic, vehicle weight scales are installed at interchanges and the like, and overweight vehicles are cracked down. As a vehicle weight scale, for example, a plurality of load cells (load detection units) and a weighing platform supported by the load cells are placed in a pit formed by digging into the ground, and a vehicle such as a truck is placed on the weighing platform. (see, for example, Patent Document 1). A gap of, for example, about 1 cm to 2 cm is provided between the pit and the weighing platform.

Such vehicle weight scales are regularly inspected and maintained and managed so that they function soundly. At the time of inspection, for example, in addition to inspection of the pit, cleaning work is performed to remove fallen leaves and sludge that have entered the pit through the gap between the pit and the weighing platform and accumulated in the pit. This is because fallen leaves and sludge accumulated in the pit may cause failures such as poor insulation of the load cell.

However, cleaning work in the pit takes, for example, about half a day by five workers, and there is a problem that much work time is required. In addition, the space in the pit is as low as about 1.25m, and the work is done in a crouching posture, which poses a great burden on the body and is difficult. Furthermore, the inside of the pit is narrow and dark, so there is a risk of occupational accidents.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the overall configuration of a vehicle weight scale gap closing member 10 according to an embodiment of the present invention. FIG. 2 shows a state in which the vehicle weight scale gap closing member 10 is arranged on a vehicle weight scale 20 . FIG. 3 shows an enlarged cross-sectional configuration of the gap closing member 10 for a vehicle weight scale. This vehicle weight scale gap closing member 10 is arranged with respect to a vehicle weight scale 20 for measuring the weight of a vehicle.

The vehicle weight scale 20 measures the weight of a vehicle traveling on a road, particularly a large vehicle, and is installed at an interchange or the like. This vehicle weight scale 20 has, for example, a load cell 22 disposed inside a concave pit 21, and a weighing platform 23 supported by the load cell 22 is disposed with a gap from the inner wall of the pit 21. ing. In this vehicle weight scale 20, for example, a vehicle to be measured is moved onto a weighing platform 23, and the load cell 22 measures the gravity of the vehicle to be measured.

For example, the pit 21 is formed in a concave shape by digging down the installation surface of the vehicle weight scale 20, and has a rectangular shape when viewed from above. The load cells 22 sense the load, and for example, four load cells are arranged corresponding to the four corners of the pit 21 . The weighing platform 23 is a platform on which a vehicle is placed, and has, for example, a rectangular shape when viewed from above corresponding to the shape of the pit 21 . The size of the weighing platform 23 is such that, for example, a large vehicle can ride on it. The weighing platform 23 is supported by a support member 24 and placed above the load cell 22 so as to correspond to the upper end of the bit 21, for example. are configured to have the same height. The top surface of the outer edge of the pit 21 and the top surface of the weighing platform 23 are made of metal such as steel. A gap between each side of the weighing platform 23 and the inner wall of the pit 21 is, for example, about 10 mm to 20 mm.

The vehicle weight scale gap closing member 10 closes the gap between the pit 21 and the weighing platform 23 . The vehicle weighing scale gap closing member 10 includes a flange portion 11 disposed so as to straddle between the upper surface of the outer edge of the pit 21 and the upper surface of the inner edge of the weighing platform 23, and the lower surface of the flange portion 11 extending downward to measure the weight. It has a leg 12 inserted into the gap between the base 23 and the inner wall of the pit 21 . As a result, the gap closing member 10 for a vehicle weight scale is designed such that the legs 12 are inserted into the gap between the weighing platform 23 and the pit 21, and the gap is covered by the flange 11 to easily close the gap. .

The collar portion 11 and the leg portion 12 are preferably made of synthetic rubber such as ethylene propylene rubber (EPM) and ethylene propylene diene diene rubber (EPDM). It is because it is excellent in durability and attachment/detachment workability. A fixing member 13 made of a magnetic sheet is preferably provided on at least a portion of the lower surface of the collar portion 11 . This is because the collar portion 11 can be stably and easily fixed so as to straddle between the upper surface of the outer edge of the pit 21 and the upper surface of the inner edge of the weighing platform 23, and it is possible to prevent the collar portion 11 from coming off during mounting. . Also, the magnetic force can be used to easily attach and detach the flange 11, which facilitates the work. The fixing members 13 may be provided on the entire lower surface of the brim portion excluding the portion of the leg portion 12, or may be provided partially at intervals in the length direction or width direction. 2, the fixing member 13 is omitted.

The shape of the flange 11 seen from above is, for example, a rectangular shape, and the width of the flange 11, that is, the length of the short side seen from above, is preferably 70 mm to 150 mm, and 90 mm to 110 mm. It is more preferable to This is because if the gap is too narrow, the gap cannot be sufficiently covered, and if it is too wide, the weight becomes heavy and the attachment and detachment work becomes difficult. The length of the flange portion 11, that is, the length of the long side as viewed from above is preferably 1 m to 4 m, more preferably 2.0 m to 3.0 m. If it is too short, the work for attaching and detaching will increase and work efficiency will be lowered. The total thickness of the collar portion 11 and the fixing member 13 is preferably 4 mm to 10 mm, more preferably 5 mm to 8 mm. This is because if the thickness is too thin, sufficient strength cannot be obtained, and if the thickness is too thick, the difference in level between the upper surface of the outer edge of the pit 21 and the upper surface of the weighing platform 23 becomes large, making it difficult for the vehicle to move.

The leg portion 12 is provided, for example, at the center portion in the width direction of the flange portion 11 so as to extend in the length direction. The width of the legs 12, that is, the length in the width direction, is preferably 6 mm to 20 mm, more preferably 8 mm to 16 mm. This is to maintain the required strength and to facilitate insertion into the gap between the pit 21 and the weighing platform 23 . The height of the legs 12 is, for example, preferably 30 mm to 80 mm, more preferably 40 mm to 60 mm. This is because if it is too low, the position is likely to shift or come off, and if it is too high, the weight becomes heavy and the attachment and detachment work becomes difficult.

For example, the gap closing member 10 for a vehicle weight scale is inserted into the gap between the weighing platform 23 and the pit 21 of the vehicle weight scale 20 so that the outer edge upper surface of the pit 21 and the inner edge of the weighing platform 23 are closed. The collar part 11 is arranged and mounted so as to straddle the upper surface. It is preferable that a plurality of gap closing members 10 for vehicle weighing scales are continuously mounted according to the size of vehicle weighing scale 20, for example, to cover the entire circumference of the gap between weighing platform 23 and pit 21. The vehicle weighing scale 20 can measure the weight of a vehicle to be measured by placing it on a weighing platform 23 with the gap closing member 10 for a vehicle weighing scale attached.

In addition, a plurality of gap closing members 10 for vehicle weight scales are continuously arranged so as to cover the entire circumference of the gap between the weighing platform 23 and the pit 21 with respect to the vehicle weight scale 20 installed at the interchange. However, even after several months had passed, the inside of the pit 21 was in good condition with no sediments or stagnant water. In addition, no detachment or displacement of the gap closing member 10 for vehicle weight scale was observed.

As described above, according to the present embodiment, the leg portion 12 is inserted into the gap between the weighing platform 23 and the pit 21 , and the flange is arranged so as to straddle between the upper surface of the outer edge of the pit 21 and the upper surface of the inner edge of the weighing platform 23 . By arranging the part 11, the gap between the weighing platform 23 and the pit 21 can be easily closed. Therefore, it is possible to prevent fallen leaves and sludge from accumulating inside the pit 21, thereby reducing the cleaning work and reducing the risk of occupational accidents. In addition, since the gap closing member 10 for a vehicle weight scale can be easily attached and detached without using a tool, the burden of work is small and it can be easily introduced.

Furthermore, if the collar portion 11 and the leg portion 12 are made of synthetic rubber, the durability and the attachment/detachment workability can be improved. In addition, if a fixing member 13 made of a magnetic sheet is provided on at least a part of the lower surface of the flange portion 11, the flange portion 11 can be easily and stably fixed, and the flange portion 11 will come off during installation. It is possible to suppress this and to easily attach and detach, so that the work can be facilitated.

Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above-described embodiments, and various modifications are possible. For example, in the above embodiments, each component was specifically described, but not all components may be included, or other components may be included.
