Description

Truck scale

Technical field

The present invention relates to a kind of weighing apparatus, particularly a kind of truck scale.

Background technology

In the prior art, truck scale body adopts horizontal single plate structure mostly, and the way that improves physical strength just increases end plate thickness.According to material mechanics principle, increase end plate thickness merely, the raising of physical strength is also not obvious; On the other hand; The one-board crossbeam is owing to can not form enclosed region; Sensor body and lead can't be protected through structure itself, are difficult to realize the protection of protection against rodents, the anti-cheating of sensor and impact, aspect the anti-nose of scale body; Existing way is that the sensor stress point is moved outward; But the stress of sensor changes, and can influence the linear sensor output characteristics, thereby and the scale body produce with transportation in stack arbitrarily and can let sensor generation physics contact sensor is caused damage.

Summary of the invention

To the deficiency that exists in the prior art, thereby the object of the present invention is to provide a kind of protection against rodents trouble, anti-sensor cheating, impact and utilize a small amount of steel just can improve the truck scale that scale body physical strength prevents nose in weighing process.

Technical scheme of the present invention is achieved in that

Among the figure: the 1-sensor main body, the 2-crossbeam, 3-sensor mounting hole, 4-sensor installing plate, the 5-grade slab, 601-master's scale body, the secondary scale body of 602-, 7-overlaps beam, 8-dividing plate, 9-back up pad, 10-force plate, 11-through wires hole, 12-web member, 13-gusset.

Embodiment

In conjunction with accompanying drawing the present invention is done further explanation:

As shown in Figure 1, truck scale comprises scale body, sensor main body 1; Said crossbeam 2 is a box-structure; In said box-structure, be provided with sensor installing plate 4, said sensor main body 1 is installed in below the said sensor installing plate 4, and the bottom surface of said box-structure offers sensor mounting hole 9; Said sensor main body 1 contacts with grade slab 5 through said sensor mounting hole 3 with the extraneous sensor main body 1 that is connected through said sensor mounting hole 3; Crossbeam 2 can form the box beam structure by a U section steel beam and scale dignity plate welding back, and the crossbeam 2 of box-structure has traditional crossbeam 2 inaccessiable physical strengths, according to the stressed principle of mechanics of materials beam; Calculate that traditional 20mm is thick, Q235 material steel plate, the composite bending modulus of high 360mm:

W1＝B×H2/6＝20×3602/6＝432000mm ³

And adopt even only thick, the high 360mm of Q235 material steel plate forming of 6mm, the box-structure girder steel of bottom width 230, its composite bending modulus is:

W2＝2×B×H2/6+250×B×(H/2)

＝2×6×3602/6+6×230×180＝507600mm ³

Relatively W1, W2 can find: the latter is the former 1.175 times, and the former cross section is 20 * 360=7200mm ², latter cross section is 6 * (360+360+230)=5700mm ², the latter is the former 0.792 times.

Above data show: the horizontal girder steel of box-structure only need utilize the material less than traditional scheme 80%, and physical strength but improves 17.5% than traditional scheme.The former is every 1mm ²The cross section is to the contribution margin=432000/7200=60mm of composite bending modulus ³, the every 1mm2 of latter cross section is to the contribution margin=507600/5700=89mm of composite bending modulus ³

Ratio between two is 1.483, and this result shows: box-structure crossbeam steel effectiveness exceeds 48.3% than traditional scheme, in theory; If by former strength criterion design, material can save 48.3%, and will consider textural element in the reality; Also save 30% steel at least, can practice thrift the steel more than the 100kg, like of the same trade the use in the whole nation to a truck scale; By conservative statistics; At least produce 200,000 truck scales every year, can practice thrift 20,000 tons of steel of steel, be worth 100,000,000 yuan; And sensor main body 1 is arranged on crossbeam 2 inside and can contact with the external world; Sensor main body 1 is had great protective effect, make its damage that in transportation, can not bump, and sensor main body 1 is hidden in and makes also in the crossbeam 2 that the lawless person is difficult to sensor main body 1 is transformed (as on sensor conductor, installing the remote controlled with signals device that is used to practise fraud additional) to reach the purpose of its cheating because of jolting of road.

Said scale body comprises main scale body 601 and secondary scale body 602; The crossbeam 2 of said secondary scale body 602 1 sides is provided with overlap joint beam 7; Said overlap joint beam 7 stretches into the said crossbeam 2 of said main scale body 602, in said crossbeam 2, also is provided with dividing plate 8, and said dividing plate 8 is two; Distance between said two dividing plates 8 is more than or equal to the width of said overlap joint beam 7; Be horizontally arranged with back up pad 9 on 8 on said dividing plate, said overlap joint beam 7 overlap joints are on said back up pad 9, and said overlap joint beam 7 is fixed between the said dividing plate 8 through coupling bolt.

Between said overlap joint beam 7 and back up pad 9, be provided with force plate 10, the distance at the said main scale body of said force plate 10 distances 601 edges is more than or equal to the distance between said sensor main body 1 and said main scale body 601 edges, so for secondary scale body 602; Because overlapped points is in secondary scale body 602 outsides, tilting moment is a negative value, after main scale body 601 combines; Eliminated the tilting moment of two scale bodies fully at binding site, can nose, and in the both sides of all scale body assemblys; Because the automotive tire pressure part is drawn the slope and disperseed,, also be not enough to surpass scale body weight moment even there is tilting moment; The scale body can nose in this part yet; And for main scale body 601, the position that is provided with of force plate 10 makes sensor main body 1 can not bear too big pressure basically, thereby has guaranteed the transport property of sensor.

On said dividing plate, also be provided with through wires hole 11, through wires hole 11 is used for the lead at scale body internal placement sensor, and said web member 12 is positioned at said sensor mounting hole 3; Ultimate range between said web member 12 and the said sensor mounting hole 3 is smaller or equal to 1cm; According to statistics, there is every year about fault of 20 percent to cause, if be 10 years by the normal serviceable life of a truck scale by mouse; Every truck scale is annual because the economic loss that mouse is caused is about just at several ten thousand yuan; Distance design between sensor mounting hole 3 and the web member 12 in 1cm, can fully stop mouse and creep into sensor internal in the sensor mounting hole 3 sensor conductor is damaged, and web member 12 is made sensor main body 1 not contact with the external world; In process of manufacture; Can not cause damage, collide stacking yet of scale body, guarantee the linear output character of sensor main body 1, for the user has avoided very big property loss to sensor main body 1.

In crossbeam 2, also be provided with gusset 13 on top and the medial surface near said scale body one side, gusset 13 can increase scale surface rigidity, prevents it and makes the local surfaces of scale body at the crossbeam place produce expendable permanent strain owing to weigh for a long time.

The foregoing description only be for explain clearly that the invention does for example, and be not qualification to the invention embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.Allly still be among the protection domain of the invention claim in any conspicuous variation of being extended out within spirit of the present invention and the principle or change.
