Abstract
The invention discloses an array-type weighing rod. A weighing body is an elastic body; strain gauges are evenly pasted onto the bottom face of the elastic body; the strain gauges are bridged into a weighing sensor; the elastic body is fixed onto a bottom frame through fastening bolts; the elastic body and the periphery of the bottom frame are welded and sealed; and a weighing signal is led out through an outlet cable arranged on the bottom frame. Compared with fixed-type axle load meters, bent plate-type axle load meters and integral-type motor truck scales widely used at present, the array-type weighing rod is reduced by 100mm in integral table board and is reduced by 26mm in integral height; when the array-type weighing rod is installed, the excavation dimension of a road bed is small, the installation is simple, and the damage to an original road surface is small; the sealing effect of the sensor is good, and the service life is long; the upper surface of the elastic body is parallel and level with the road surface; and the system does not need to be provided with a drainage and is free of maintenance.
Description
Technical field
The present invention relates to a kind of weighing device that is used for vehicle weighing, especially be directed to array that automobile axle (wheel) heavily the weighs rod of weighing.
Background technology
From in June, 2004, the nationwide has been organized the vehicle overload overload and has been concentrated improvement work.In these years, concentrate and to control ultra work and obtained phasic results, the vehicle situation that seriously transfinites is curbed, and the traffic safety situation is clearly better.Present stage, the meter that is used to administer overrun and overload work is reseted and is equipped with, and mainly contains following two kinds of forms: 1, fixed axle load meter, bended plate type axle load meter; This type meter is reseted and mainly is aimed at heavy the weighing of automobile axle (wheel) fully, calculates gross combination weight according to software algorithm again, this type weighing platform table top broad; The road bed excavation is bigger; Long construction period damages greatly former roadbed, and maintenance cost is high; 2, it mainly is that the weighing platform table top is huge to the weighing of automobile gross weight that integral automobile weighing apparatus, this type meter are reseted with fullying, have in addition above 20 meters long, the road bed excavation project is huge, long construction period, maintenance cost is big.
Summary of the invention
In order to overcome the deficiency that above-mentioned technology exists, it is little to the purpose of this invention is to provide a kind of table top, and construction is simple, and short construction period is non-maintaining, be directed to array that automobile axle (wheel) the weighs rod of weighing.
Technical scheme of the present invention realizes in the following manner:
A kind of array rod of weighing, Weighing body is an elastic body, is uniformly distributed with the subsides foil gauge in the elastic body bottom surface; Foil gauge group bridge becomes LOAD CELLS; Elastic body is fixed on the underframe through fastening bolt, elastic body and the sealing of underframe welded, and weighing-up wave is drawn through the outlet cable that is installed on the underframe.
Foil gauge is two-way vertical strain sheet, can experience two vertical direction simultaneously and drawn and compressive strain.
Foil gauge is totally ten two composition Wheatstone bridges, and each brachium pontis has three foil gauges.
The foil gauge arrangement mode is array format.
This elastic body adopts superior alloy steel 40CrNiMoA to make, and quenching and tempering hardness is to HB280 ~ HB300.
Good effect of the present invention is: with widely used fixed axle load meter, bended plate type axle load meter, integral automobile weighing apparatus are compared at present; The array provided by the present invention rod of weighing: 1, the narrow 100mm of whole table top; Whole height hangs down 26mm; So road surface foundation excavation size is little when installing, install simply, little to former pavement destruction; 2, elastic body 1 and the sealing of underframe 3 welded, the sensor good sealing effect, the life-span is long; 3, array fully seamless being poured on the roadbed of rod of weighing, elastic body 1 upper surface is concordant with the road surface, and system need not establish draining, and is non-maintaining.
Description of drawings
Fig. 1 is a plan structure synoptic diagram of the present invention.
Fig. 2 is the sectional structure synoptic diagram of Fig. 1.
Fig. 3 is uniformly distributed with the structural representation that pastes foil gauge for the elastic body bottom surface.
Fig. 4 becomes Hui Sitong full-bridge circuit schematic diagram for vertical strain sheet group bridge of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is implemented to be further described:
Can find out by Fig. 1, Fig. 2, Fig. 3, Fig. 4: be uniformly distributed with in elastic body 1 bottom surface and paste vertical strain sheet 2; Vertical strain sheet 2 can be experienced pressurized and tensile strain simultaneously, and 2 groups of bridges of vertical strain sheet become the Hui Sitong full-bridge circuit, and elastic body 1 is fixed on the underframe 3 through fastening bolt 4; Elastic body 1 and underframe 3 welded sealing 5; When elastic body 1 surperficial pressurized, foil gauge 2 is experienced the microstrain of elastic body 1, and converts resistance variations to; Through weighing-up wave of Wheatstone bridge output, weighing-up wave is drawn through the outlet cable 6 that is installed on the underframe 3.It can also be seen that by Fig. 4 foil gauge is totally ten two composition Wheatstone bridges, each brachium pontis has three foil gauges.It can also be seen that by Fig. 3: the foil gauge arrangement mode is array format.
