Abstract
A checker for balancer without weights of the utility model is characterized in that a checking flat base of a weighing sensor is arranged on the balancer checked under an upswept frame. A hydraulic equipment for applying force is arranged between the checking flat base and the upswept frame, and the weighing display controller is connected with the weighing sensor to display the standard value. A shim plate can also be arranged between the hydraulic equipment and the top of the upswept frame, and the shim plate can be made an entirety with the upswept frame. The utility model simplifies greatly checking procedure of the quality balancer, conserves manpower, force and financial power, solves effectively the problems that high carriage charges of the long distance weight which is checked by the big quality balancer, long cycle length, safety without guarantee and placing of the certified weights of the big quality balancer with small surface. With small volume and easy operation, the manufacturing cost is only 1/10 times of the conventional method of verification.
Description
Technical field
The utility model relates to a kind of weighing apparatus, and specifically weighing apparatus does not have the weight detecting device.
Background technology
Develop rapidly along with market economy, newborn enterprise and foreign capital affiliate increase day by day, the requirement of weighing apparatus under all trades and professions various types and various environment as one of measurement instrument differs, and a difficult problem has appearred in the calibrating of particularly big weighing and the big little table top weighing apparatus of weighing, as; Problems such as the remote counterweight transportation difficulty of big quality weighing instrument verification, expense is big, the cycle is long, safety does not have guarantees and greatly the counterweight examined and determine of the little table top weighing apparatus of quality (axle weight scale) can't place problem such as can not examine and determine and all give the gage work person has proposed a problem that presses for solution, no weight detecting device is that the static calibrating installation of axle load meter of big quality weighing apparatus-especially and truck scale is a problem of inquiring in the world and studying so far always.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of weighing apparatus not have the weight detecting device.
The utility model is on the basis of the LOAD CELLS of modern high sensitivity, pin-point accuracy and corresponding weighing displaying controller, and the suitable mutually upswept frame structure of yardstick that is configured to tested weighing apparatus with hydraulic means, thereby substitute the calibration method of the artificial accumulation of only using some standard test weights.
The technical scheme of utility model is to put the calibrating platform that LOAD CELLS (standard transducer) is arranged on the tested weighing apparatus under upswept frame, between this calibrating platform and upswept frame, lay the hydraulic means of an application of force, and show its standard value on the weighing displaying controller that LOAD CELLS is electrically connected.
For examining and determine conveniently, also can between hydraulic means and framework top, certain thickness backing plate be set, this backing plate can be made one with framework; Equally, the quality of the yardstick of framework and tested weighing apparatus or yardstick are suitable.
The utility model has been simplified the calibrating operation of big quality weighing apparatus greatly, has saved human and material resources and financial resources, has filled up the blank of no weight detecting weighing apparatus, can make the numerous metering validation activity weighing apparatus manufacturer in the whole nation save a large amount of funds spendings.
Description of drawings
Fig. 1, basic structure synoptic diagram of the present utility model.
Fig. 2, perspective view of the present utility model.
Wherein: 1, weighing displaying controller; 2, upswept frame; 3, backing plate; 4, hydraulic means; 5 tested weighing apparatus; 6, calibrating platform; A, LOAD CELLS.
Embodiment
As putting the calibrating platform 5 that LOAD CELLS A is arranged on the tested weighing apparatus 6 of Fig. 1 under upswept frame 2, lay the hydraulic means 4 of an application of force at this calibrating platform 5 and 2 of upswept frames, described weighing displaying controller 1 is electrically connected to show its standard value with LOAD CELLS A.
The upper-lower position of described tested weighing apparatus 6 and calibrating platform 5 can exchange.
Also can between hydraulic means 4 and upswept frame 2 tops certain thickness backing plate 3 be set, this backing plate 3 can be made one with upswept frame 2.
Described weighing displaying controller 1 as commercially available XK series of products; Upswept frame 2, backing plate 3 are metal physical construction; Hydraulic means 4 is a QYL series lifting jack product; Steady sensors A is each series of resistance-strain type (as: LC, LFR, SQ) model LOAD CELLS product or each serial LOAD CELLS product of electromagnetic type; Tested weighing apparatus 6 is fixed electronic platform scale, fixed weighing apparatus, electronic vehicle weighing apparatus, the electronics axle load meter (axle weight scale) etc. gone up electronically.
If when adopting conventional calibration method, can't examine and determine little table top weighing apparatus, and big table top is needed reach 100 tons with counterweight, and remote transportation problem is arranged, the calibration interval are long, minimum 2 days; Expense reduces greatly when adopting the utility model, and the calibration interval are short, maximum 2 hours.The remote counterweight trucking costs that has solved big quality weighing instrument verification effectively is big, the cycle long, safety does not have guarantee and the big little table top weighing instrument verification of quality counterweight is placed problem, and volume is little, easy and simple to handle, and cost has only 1/10 times of conventional calibration method.
