Abstract

The utility model relates to a suspension surface support span-reducing weighing platform, which belongs to the measuring device field and mainly solves the problem of high manufacturing cost of the weighting platform in the prior art. The utility model adopts a new weighting platform whose both ends of the platform surface are appropriate suspended. The weighting platform is adjoined with the spacing technique for preventing warp. The weighting platform is able to reduce the span between the fulcrums of a sensor effectively. The gravity and the force arms of the fulcrums are reduced. Thus, the functions of material saving and cost reduction are realized. Compared with the common weighting platform with the same measuring range, the utility model can save the cost with a third part. Especially, the utility model is suitable for producing the reinforced concrete weighting platform and can be widely used for the auto scale and the railroad track scale.

Description

Outstanding face supports the span-reducing weighing platform

1, affiliated technical field

The outstanding face of the utility model supports the span-reducing weighing platform and belongs to the measurement mechanism field, is specifically related to the improvement of the weighing platform structure of a kind of electronic vehicle weighing apparatus and electronic track scale.

2, background technology

The weighing platform structure of existing truck scale track scale, its common characteristic is arranged, the strong point that the weighing platform table top is set at the termination corner location near weighing platform is the sensor installation site, the overwhelming majority of weighing platform table top is between the strong point of weighing platform table top, number of patent application for example: 03126109.4 raise-free electronic vehicle weighing apparatus, the strong point of weighing platform table top is fixed on apart from one of termination corner location minizone very, upwarp from preventing to weigh and to be starting point, weighing platform mesa supports link position is set in by the termination corner location, ensured on the weighing platform structure under the state of weighing, not produce and upwarped phenomenon, but span is big between the weighing platform mesa supports point, the gravity that weighing platform mesa supports point produces is apart from big, mechanical property to table top requires high, must meet the demands with the quality and the consumption of the material of making table top, existing truck scale is with regard to cost, the weighing platform of weighing accounts for 2/3 of truck scale total cost, the production cost that reduces truck scale is mainly by reducing the cost of weighing platform table top, a truck scale table top price is in tens thousand of units, not only having economized material but also weighing platform structure unaffected is that manufacturer is desirable, but existing weighing platform structure is not accomplished.

3, summary of the invention

The purpose of this utility model is: overcome the high shortcoming of prior art weighing platform cost, provide a kind of outstanding face to support the span-reducing weighing platform, the utility model has a mind to sensor is placed in the middle of table top, shorten the span between the LOAD CELLS strong point, by solving with the anti-position limiter device that sticks up that weighing table is easy to generate the problem that table top upwarps on the automobile, this weighing platform props up the span that claims between point because can effectively reduce sensor, so making the required not modification intensity index with material of table top can reduce greatly, the deformation resistance performance of table top own strengthens, thereby can reduce the required material of using of table top, produce the low weighing platform of price.

The purpose of this utility model is achieved in that

A kind of outstanding face supports the span-reducing weighing platform, mainly comprises weighing platform table top, LOAD CELLS, ground, grade slab, stop means composition.The support and connection position that LOAD CELLS is supporting the weighing platform table top is to determine by S/10≤L≤S/2, and wherein: S is a monolithic weighing platform table top length, and L is the distance of limit, weighing platform table top gateway to close LOAD CELLS support and connection position; Ground is fixed with the anti-stop that sticks up that restriction weighing platform table top upwarps, and its anti-sticking up has the adjustable anti-gap of sticking up between stop and the weighing platform table top.The weighing platform table top that this outstanding face supports the span-reducing weighing platform is with steel construction or reinforced concrete structure or steel concrete composite structure or rod-pulling type mesa structure formation.

This outstanding face supports the span-reducing weighing platform, can constitute weighing platform table top or 2 to the 3 adjacent connection growth of weighing platform table top weighing platform table tops or the synthetic long weighing platform table top of interval group separately by 1 weighing platform table top.

Owing to adopted such scheme, effectively reduce sensor and propped up the span that claims between point, better solved the problem that the weighing apparatus table top of weighing on the automobile upwarps by the anti-position limiter device that sticks up, the used steel of truck scale or track scale are significantly reduced, and the deformation resistance performance strengthens, outstanding face supports the span-reducing weighing platform can be reduced about several ten thousand yuan than conventional same model truck scale or track scale cost, installs also very convenient.
