The utility model has the technical proposal and structure that in the width direction of the weight weighing table body (1), i.e. both edges of the top and the bottom weight weighing table bodies (1) are respectively provided with a bridge approach (2); two columns of narrow grooves (4) are arranged in the width direction of the table top; over-eccentric load handles (5) connected by a hinge are arranged at both ends of the weight weighing table body (1); blind holes or blind channels are arranged at the back side of the weight weighing table body (1) near both sides to form a nonlinear strain beam (3); a deformeter (6) is arranged on the nonlinear strain beam (3). The bridge approach (2) is in either arc shape or step shape, and the envelope curve of the outline is in arc shape; the narrow groove (4) is either a vertical angle channel or a round angle channel; the width value of the nonlinear strain beam (3) is formed according to the nonlinear variation of big-small-big-small-big.
Description
Affiliated field
The utility model relates to a kind of vehicle weight checkout equipment, especially at the heavy detection of automobile axle (wheel).
Background technology
For solving goods transport vehicle overrun and overload transportation problem; reduce the generation of traffic safety accident; protection people's life and country, collective, personal property safety; the whole nation is large-area has carried out goods transport vehicle overrun and overload improvement work, so the monitoring equipment of and gross weight heavy about automobile axle (wheel) is further developed.At present, the portable Platform balance for shaft weight of producing (weighing plate) mainly is three kinds both at home and abroad, a kind of is the version that parts assembling or sensor embed weighing plate, and promptly the sensor with many low external forms embeds the structure of forming weighing platform in an alloy steel framework or the aluminium alloy plate.Another is the portable weighing plate of one-piece construction, it is by some blind holes of processing or blind groove in close two the supporting place symmetries of duralumin, hard alumin ium alloy or high-strength alloy steel plate medial recess district, the monoblock type LOAD CELLS that produces many shear beams and form, i.e. weighing plate.These two kinds of versions are at present domestic all a use, former structure complexity wherein, and the table top height from great, is not easy to carry, and the impact to sensor and weighing platform framework especially in use is bigger, influences the serviceable life and the weighing precision of weighing unit system; Though the portable weighing plate of one-piece construction overcomes the defective that the former sensor and weighing platform framework impact, table top oneself height and weight are still limited.In use the both will be equipped with access bridge, and generally speaking, the access bridge deadweight has 50~60kg, gives to move to use and brings very big inconvenience.In view of the situation, at present domestic also have another kind to improve structure, promptly carries the weighing plate of access bridge, and its profile is lower, and weight is lighter, is easy to carry.But, because this weighing platform table top is less,, generally to want strictness to limit car, otherwise be directed to the car of crossing of same state not near the weighing platform center for the security consideration of eccentrically loaded susceptibility and weighing platform, the output variation of weighing is bigger.
Summary of the invention
The purpose of this utility model is a kind of portable Platform balance for shaft weight of being convenient to move of developing at above deficiency, and is characterized in anti-eccentric load and crosses the unbalance loading ability stronger, and the weighing area sense is very strong, and table top is ultra-thin, the deadweight ultralight.Technical solutions of the utility model and structure are: on weighing unit main body 1 Width, promptly on two limits of weighing unit main body 1 access bridge 2 is arranged up and down, the narrow groove 4 of two row is arranged on broad ways on the table top, weighing unit main body 1 two ends have by the hinged unbalance loading handle 5 of crossing, near the place, both sides blind hole or blind groove are arranged at weighing unit main body 1 back side, form nonlinear strain beam 3, strainometer 6 is arranged on the nonlinear strain beam 3; Access bridge 2 or be arc perhaps is stepped, and its outline envelope is an arc; Narrow groove 4 or trough with straight angle, or fillet groove; The width value of nonlinear strain beam 3 constitutes by big-little-big-little-big nonlinearities change.Weighing unit main body 1 adopts the high-strength rigid aluminium alloy; on the weighing unit Width; promptly there is access bridge 2 on two limits of weighing unit main body 1 up and down; the narrow groove 4 of two row is arranged on the broad ways; in order to dredge whole weighing area stress state; weighing unit main body 1 two ends have by the hinged unbalance loading handle 5 of crossing; play the effect of position limitation protection; be processed with blind hole or blind groove at weighing unit main body 1 back side near the place, both sides; form nonlinear strain beam 3; strainometer 6 is arranged on the nonlinear strain beam 3, by on the nonlinear strain beam to the output of strain signal, to reach the purpose of weighing.
The beneficial effects of the utility model are: anti-eccentric load is with the unbalance loading ability is stronger excessively, and the weighing area sense is very strong, and table top is ultra-thin, the deadweight ultralight.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described.
Shown in Fig. 1,2,3,4,5,6,7,8,9, referring to Fig. 2,3.On the weighing unit main body 1 of the high strength hard aluminum alloy materials of 700 * a 405 * 26mm, the domatic access bridge of arc 2 is processed in both sides on the positive broad ways, processing two is listed as narrow groove 4 on the table top simultaneously, dredge the whole distorted area of weighing therebetween, increase the length of the sample region of weighing by the sudden change of geometric configuration, and make that whole in the longitudinal direction loading zone is stressed evenly, clear and definite, thereby make the output of strainometer 6 make moderate progress for the unbalance loading on the length direction.As shown in Figure 8, the narrow groove 4 of these two row also can be processed into the groove of band fillet.As shown in Figure 9, the back side is processed with blind hole corresponding to narrow groove 4 and blind groove amounts to 9, form nonlinear strain beam 3 and amount to 8 pairs, pass through on nonlinear strain beam 3 broad ways width value by greatly-little-big-little-big nonlinearities change, to adjust the eccentrically loaded output of weighing unit.There is uniaxial strain gage 6 to amount to 32 on the nonlinear strain beam 3, strainometer 6 interleaved series are formed Wheatstone bridge, and draw input, output terminal, input end supply incentive power supply, weighing unit main body 1 is subjected to the load of sending a car, and just can produce signal at output terminal, and automobile balance is by after the weighing unit main body 1, weighing unit main body 1 will obtain the weight of automobile axle (wheel) and car load successively, thereby finishes a monitoring of sending a car.Have by the hinged unbalance loading handle 5 of crossing at the two ends of weighing unit main body 1; when this product placement is on the road surface; be in same plane with weighing unit main body 1; not influencing weighing unit main body 1 during normal load weighs; when unbalance loading took place when; the most of pressure of doughnut bears by crossing unbalance loading handle 5, thereby plays position-limiting action, protection weighing unit main body 1.
