Description

[Detailed Description of the Invention] The present invention relates to a structural improvement of a load loading platform for a large weighing machine, particularly a truck scale.

As shown in Figure 1, it has been known that the loading platform of large weighing machines such as truck scales has a split structure to improve transportability and ease of installation, and many have actually been installed. There is.

By the way, this type of load loading platform is divided into a plurality of platform plates 1, . . . , 1 in the longitudinal direction, as shown in FIG. 1, and also shown in FIGS. 2 to 4 main girders 2,..., 2 are arranged in the longitudinal direction of the loading platform, and these main girders 2,...,2 are arranged in the longitudinal direction of the loading platform.
..., 2 cross-joining crossbeams 3, ..., 3, 4, ..., 4
are arranged at regular intervals in the longitudinal direction, and the main girders 2,...,2
After assembling to the main girders 2, ..., 2 so that the top surfaces of the cross beams 3, ..., 3, 4, ..., 4 match, the above-mentioned divided base plates 1, ..., 1 are set up. It has a structure.

In this kind of structure, main girders 2,...,2 and cross girders 3,
..., 3, 4, ..., 4 are integrated by welding at the manufacturing plant side, which would make transport difficult. The girder 2 and the cross beams 4,..., 4 and the main girder 2 and the divided loading base plates 1,..., 1 are all connected by bolts and nuts, which requires a significant number of parts and requires assembly at the installation site. The disadvantage was that the work was difficult and took a long time.

The present invention has been made in consideration of the shortcomings of such conventional split structures, and aims to provide a split structure for a truck scale which takes into account the strength structure required for a truck scale and which, by blocking the loading platform structure as much as possible within the maximum transport dimensions, reduces the number of parts and improves connectability, thereby significantly improving manufacturability and ease of installation at the installation site.

Therefore, the loading platform of the truck scale according to the present invention basically has three parts along the longitudinal direction of the loading platform.
The left and right sides, over which the truck wheels actually pass, have sufficient width to take into account differences in the distance between truck wheels depending on the model, the possibility of skewing, etc. While it is formed as a pair of left and right load carrying units with sufficient strength to last, the center part between the left and right load carrying units is formed as a lid plate that simply covers the space between the left and right load carrying units, and is extended in the longitudinal direction. Using a split cover plate divided into appropriate lengths, at the installation site, the left and right load carrying units are bolted to the cross beam supported by a pair of load cells in the pedestal, and the split cover plate is inserted between both units. The structure allows the installation to be completed simply by placing it on the vehicle.

Hereinafter, the present invention will be described in more detail based on illustrated embodiments.

As shown in FIG. 4, the load loading platform 10 of the truck scale according to the present invention has a basic structure divided into three parts in the longitudinal direction, and all of the loaded load of the truck to be weighed is transferred through the wheels of the truck to be weighed. a pair of left and right load carrying units 11 and 12 that receive the
A plurality of cover plates 13, .
and cross beams 14 and 15 that support both longitudinal ends of the left and right pair of load carrying units 11 and 12, respectively.

As shown in FIGS. 5 and 6, a pair of left and right load loading units 11 and 12 are connected to a load loading platform 10
It has a symmetrical structure with respect to the center line in the longitudinal direction, and has a load-loading base plate 17 made of a steel plate having the necessary length and width and sufficient thickness to withstand the applied load; A pair of main girders 18, 19 with an I-shaped cross section that is slightly shorter than the length of the plate 17, and a plurality of reinforcing cross beams 20,..., 20 that connect the pair of main girders 18, 19 at appropriate pitches in the longitudinal direction. and end cross beams 21, 21 whose tips protrude inward by a certain amount along both edges of the load carrying base plate 17.

The load-bearing base plate 17 has different wheel widths due to differences in wheels, etc., and furthermore, as shown by the imaginary line in FIG. Even if you enter the
The cover plate 13 is designed to have a width that is equal to or suitably larger than the width of the cover plate 13 in the center so that the wheels W, W of the truck T can ride on it.

Further, among the pair of main girders 18 and 19, the main girder 18 on the outside in the width direction of the truck scale 10 is located slightly inside the outer edge 17a of the load carrying base plate 17, and its upper surface 18a and the load While the lower surface of the loading base plate 17 is welded, the inner main girder 19
is arranged so that about half of the width of its upper surface 19a extends inward from the inner edge 17b of the load-loading base plate 17, and is welded to the load-loading base plate 17, thereby increasing the tension of the upper surface 19a of the main girder 19. The chime 19b forms a support portion on which the side edge of the cover plate 13 is placed and supported. Furthermore, the above-mentioned reinforcing cross beams 20,..., 20
(See Fig. 5) are welded to the sides of the pair of main girders 18 and 19 and the lower surface of the load-loading base plate 17,
Increases the bond strength in the width direction of the plate.

On the other hand, on the lower surface of each cover plate 13 that covers the space between the pair of left and right load carrying units 11 and 12 having the above structure, when the cover plate 13 is placed between the pair of projecting edges 19b and 19b, , at a position substantially abutting the sides of the overhanging edges 19b, 19b,
A pair of left and right angles 22, 22, which are slightly shorter than the length of the cover plate 13 in the longitudinal direction, are welded together,
The left and right angles 22, 22 are used to position each cover plate 13 in the plate width direction.

Note that the longitudinal positioning of the cover plates 13, . This is done by abutting the end faces of the pair of angles 22, 22 of the cover plate 13 located thereon.

The pair of left and right load carrying units 11 and 12 are assembled in advance as a unit at a manufacturing factory,
Each cover plate 13,
..., 13, and the crossbeams 14, 15, are transported by truck or the like.

As shown in FIGS. 7 and 8, the load carrying units 11 and 12 transported to the installation site are first placed on the cross beams 14 and 15 supported by a pair of load cells 25 and 25 at the front and rear parts of the installation pedestal 24, respectively. After arranging the
15 and bolt holes b provided at both longitudinal ends of each main girder 18, 19 of each load carrying unit 11, 12.
They are interconnected by nuts (not shown).

The load carrying units 11 and 12 are connected to the crossbeams 14 and 15.
After the scale is set up, the cover plate 13 is successively placed between the load carrying units 11 and 12, thereby making it possible to complete the installation of the truck scale easily and in a short time.

In the above embodiment, a normal truck scale was explained, but in the case of a weighing machine for a vehicle such as a trailer truck, as shown in FIGS. 9 and 10, a truck scale 10' The divided front and rear load loading platforms 30 and 31 are formed in the same manner as in the above case, and a pair of A common cross beam 33 supported by load cells 32, 32 may be arranged, and a total of six load cells 32, including the load cells 32, .

As described above, in this invention, since the area on which the live load is actually applied is limited to both sides of the truck scale through which the truck wheels pass, it is possible to connect these sides to the left and right sides with sufficient load-bearing strength. The left and right load carrying units are bolted onto a crossbeam supported by a pair of load cells, and the space between the left and right load carrying units is covered with a cover plate divided in the longitudinal direction. The present invention provides a loading platform for a truck scale.

According to the present invention, the number of parts of the truck scale can be significantly reduced, material costs can be reduced, and the left and right load carrying parts can be made into a unit and manufactured in advance in the manufacturing factory. This makes installation work at the installation site extremely easy and quick.
