Abstract
The utility model relates to a fixed electronic weighing apparatus for weighing more than 2 tons, composed of a weighing platform plate, an auxiliary supporting beam, a ball supporting structure for supporting the weighing platform plate on the auxiliary supporting beam, load bearing knives arranged under the auxiliary supporting beam and having coaxial lines with the ball supporting structure, an L-shaped lever for supporting the knife edge of each load bearing knife, a connecting lever connected with one end of the L-shaped lever, the other L-shaped lever connected with the connecting rod and a straight lever, a sensor connected with one end of the straight lever and a weighing display meter communicated with the sensor through signals. The fixed electronic weighing apparatus lowers the harsh requirement for the rigidity and the flexibility of a weighing platform part, saves steel and uses little sensor, and the manufacturing cost of the utility model is reduced about 40 percents.
Description
The utility model relates to a kind of fixed electronic scale, is suitable for the weight more than 2 tons is weighed.
At present, the fixed weighing apparatus more than 2 tons of widespread use has mechanical, dynamo-electric association class and full-electronic class.With regard to dynamo-electric association class electronic scale, all form by weighing platform plate, Ball support structure, sensor and weighting display instrument.With regard to above-mentioned three class weighing apparatus, all there is a common defective, promptly in order to guarantee weighing precision, rigidity requirement to weighing platform is very strict, must satisfy the amount of deflection index of weighing platform plate, must increase steel using amount and big model joist steel or channel-section steel, therefore the weighing apparatus difficulty of processing is big, and manufacturing cost is also higher.
The purpose of this utility model just is: design a kind of fixed electronic scale of dynamo-electric combination, overcome the harsh requirement to weighing platform panel stiffness and amount of deflection, reduce steel using amount, reduce the difficulty of processing and the manufacturing cost of weighing apparatus.
The utility model is to realize its purpose like this: this weighing apparatus includes the weighing platform plate, the Ball support structure of supporting weighing platform plate, the sensor of sensing gravity, be the weighting display instrument of signal communication with sensor, design has the aiding support beam below the weighing platform plate, the weighing platform plate passes through the Ball support structure support on the aiding support beam, below the aiding support beam, be equiped with load pivot with each Ball support structure coaxial cable, the knife edge bearing of each load pivot is on a L type lever, L type lever one end and connecting rod load, connecting rod is by another L type lever and straight lever load mutually, straight lever one end and sensor load.
The utility model also can achieve the goal like this: four Ball support structures are set between weighing platform plate and the aiding support beam at least, each Ball support structure is loaded on seaming chuck on the weighing platform plate by pairing, be loaded on the push-down head on the aiding support beam, the fulcrum ball that is fitted between the push-down head is formed.
The corner of each L type lever of the present utility model, a termination of each straight lever are bearing on the fulcrum.
Because the utlity model has the said structure design, when being pressed on the weighing platform plate by the object of weighing, gravity passes to the aiding support beam by the Ball support structure, load pivot through the coaxial cable assembling passes to L type lever again, subtract power and change direction of transfer, by connecting rod, after another L type lever subtracts power and change direction of transfer, drive two straight levers, merge the traction sensor, gravitational cue is become electric signal, give weighting display instrument, after treatment, demonstrate the weight of weighed object.Because this weighing apparatus design has the aiding support beam, the weighing platform plate only need satisfy bending strength, the aiding support beam is finished amount of deflection and is required to get final product, Ball support structure and the assembling of load pivot coaxial cable, the moment of flexure that gravity produces the aiding support beam is minimum, compares with similar dynamo-electric convolution electronic scale, overcome harsh requirement greatly to the amount of deflection and the rigidity of weighing platform plate, the steel using amount of weighing platform part descends significantly, also needn't be with big model joist steel or channel-section steel, and the difficulty of processing of weighing apparatus reduces greatly.Simultaneously, sensor is only used one, and needn't be below each Ball support structure sensor installation.Therefore, in sum, the manufacturing cost of weighing apparatus also reduces greatly, reduces cost 40% approximately.
Further specified below in conjunction with drawings and Examples, but be not limited only to this.
Fig. 1 is a general structure synoptic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model weighing platform plate, Ball support structure, load pivot part;
Fig. 3 is the A-A cut-open view of Fig. 2;
Fig. 4 is the structural representation of the utility model aiding support beam.
As shown in FIG., this weighing apparatus is by weighing platform plate 10, aiding support beam 14, weighing platform plate 10 is supported on Ball support structure on the aiding support beam 14, be loaded on the load pivot 2 that is the coaxial cable assembling below the aiding support beam 14 with the Ball support structure, support the L type lever 1 of each load pivot 2 edge of a knife, the connecting rod 3 that connects L type lever one end, straight lever 5,8, another L type lever 4 of load connecting rod 3 and straight lever 5,8, with straight lever 5, the 8 one ends sensor 6 of load mutually, the weighting display instrument 7 that is signal communication with sensor 6 is formed.L type lever the 1, the 4th is in order to subtract power and change power transmission direction.Four Ball support structures are set between weighing platform plate 10 and the aiding support beam at least, generally are located at four bights, also can set up the Ball support structure, corresponding load pivot 2 and the L type lever (so easy to understand is in addition the drawing) set up not more on four limits.Each Ball support structure by pairing be loaded on seaming chuck 11 on the weighing platform plate 10, be loaded on the push-down head 13 on the aiding support beam 14, the fulcrum ball 12 that is fitted between the upper and lower pressure head 11,13 is formed.One termination of the corner of each L type lever, each straight lever 5,8 is bearing on the fulcrum 9, is expansion bearing.The sensor 6 of this weighing apparatus is a prior art, finished product, but market choose, as pull-type sensor of LYB (s) type etc.Weighting display instrument 7 also is a known technology, and that uses on weighing with existing electronics is similar, can select approved product 8140 etc. for use.Because this electronic scale design has aiding support beam 14, load pivot 2 and L type lever 1, connecting rod 3, another L type lever 4, straight lever 5,8, organically constitute one, only with a sensor, compare with the fixed electronic scale of similar dynamo-electric combination, the rigidity of weighing platform, the severity that amount of deflection requires are reduced greatly, use steel and needn't also not be used in and install sensor under each Ball support structure, therefore less with big model I-shaped or channel-section steel etc., the difficulty of processing of weighing apparatus reduces greatly, manufacturing cost reduces greatly, reduces by 40% approximately.
