Abstract
Te present utility model discloses a digital type hopper scale checking apparatus of which the checking is quick and correct and the signals are stable.The apparatus comprises a high-precision hydraulic pump, a jack, a bearing head and a weighing sensor of a hopper scale to be checked, the apparatus is characterized in that a digital type weighing sensor is installed vertically between the bearinghead and the weighing sensor of a hopper scale to be checked, a plurality of digital type weighing sensors are connected into a digital type wiring box, and the digital type wiring box transmits digit signals through a bus to a computer for processing. Compared with the prior analog sensor checking apparatus, the utility model can ensure the safety and reliability of signal receiving and transmitting because digital signals can be transmitted and processed stably, and the utility model has a wide market outlook.
Description
Technical field
The utility model relates to the Measuring and testing field, particularly relates to a kind of digital checking out device of bunker scale of industrial batching weighing.
Background technology
The verification of bunker scale, particularly wide range bunker scale or substitute, traditional calibration steps is to use calibration of weight, but this traditional method has been wasted great amount of manpower and material resources and time in the loading and unloading of counterweight, adjustment process, and general every platform balance verification needs 2～3 hours.When bunker scale puts the back into operation when producing contradiction because checking procedure is loaded down with trivial details, time-consuming with the rhythm of production of anxiety through preliminary calibrating, carry out verification seldom again, because long-play is difficult to guarantee measuring accuracy, produces bigger influence for controlling of production process and cost accounting.And existing mainly selecting for use by hydraulic loaded mechanism, standard comparison sensor, the special-purpose calibration equipment that Displaying Meter is formed.Work efficiency has improved 10～40 times than classic method, and greatly reduces working strength of workers, but the analog sensor that is used to compare is vulnerable to the external environment influence, a little less than the antijamming capability, is not easy to transmission and receives and data processing.And every sensor force-bearing situation of bunker scale is difficult for monitoring, causes the inconvenience of angle modulation difference.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of quick and precisely, the digital hopper-balance checker of signal stabilization.
The technical scheme that the utility model adopted is: the utility model comprises high-precision hydraulic pump, voltage stabilizing energy storage device, lifting jack, stressed carrier head and by verification bunker scale LOAD CELLS, described high-precision hydraulic pump replaces traditional counterweight, as this device source pressure, be vertically installed with digital LOAD CELLS at described stressed carrier head with between by verification bunker scale LOAD CELLS, a plurality of described digital LOAD CELLS are with inserting a digital terminal box, and described digital terminal box is handled digital signal transfers by bus in computing machine.
Described digital transducer mainly is made up of analog sensor, digital conditioning plate.The numeral conditioning plate is installed in analog sensor inside, and whole digital sensor is an integral body (as Fig. 1).
The digital bunker scale verification software that digital signal is calculated compare of analysis is housed in the described computing machine.
Described is pressure type by the force way of verification bunker scale LOAD CELLS and digital LOAD CELLS, during operate as normal before this high-precision hydraulic pump by the fluid valve door switch system is exerted pressure, hydraulic oil is exerted pressure by a hydraulic circuit logarithm lifting jack, further the piston by lifting jack passes to stressed carrier head with pressure again, described stressed carrier head produces pressure vertically downward, makes described digital LOAD CELLS be subjected to identical pressure.
The beneficial effects of the utility model are: the novel sensor of a kind of input analog amount of digital transducer that the utility model adopts, output digital quantity.It is with total digitalization, two-way serial communication controlled, multiple access is the basis, can connect separately independently field apparatus, can carry out functions such as diagnosis, control, maintenance, compare existing analog sensor, be not easy to be subjected to environmental interference, be convenient to transmission and receive and information processing, signal stabilization is good.

Embodiment
As Fig. 2, shown in Figure 3, the utility model comprises a type framework 4, high-precision hydraulic pump, voltage stabilizing energy storage device, lifting jack 1, stressed carrier head 3 and by verification bunker scale LOAD CELLS 5.Be vertically installed with digital LOAD CELLS 2 at described stressed carrier head 3 with between by verification bunker scale LOAD CELLS 5, describedly placed on the sensor load crossbeam 6 by verification bunker scale LOAD CELLS 5 and digital LOAD CELLS 2, a plurality of described digital LOAD CELLS 2 are with inserting a digital terminal box, described digital terminal box is handled digital signal transfers by bus in computing machine, the digital bunker scale verification software that digital signal is calculated compare of analysis is housed in the described computing machine.
The source pressure of this device is provided by the high-precision hydraulic pump, after performing zeroing work, open hydraulic valve, hydraulic oil is exerted pressure simultaneously by a hydraulic circuit oil pipe logarithm lifting jack, jack piston descends, pressure is passed to stressed carrier head, described stressed carrier head produces pressure vertically downward, make described digital LOAD CELLS be subjected to identical pressure, in described digital LOAD CELLS, convert electric signal to stable digital signal by analog to digital converter, and be transferred to and carry out analyzing and processing in working computer or the laptop computer, and show a standard value of current system, will be by the standard value contrast therewith of the numerical value of verification bunker scale weighing and sensing instruments and meters demonstration, analyze, confirm that load can be to being demarcated and parameter modification by the instrument of verification bunker scale LOAD CELLS after reaching full scale.
When adopting hydraulic system to carry out verification, under being no more than, should be forced into full scale earlier by the situation of verification bunker scale LOAD CELLS load, observe the video data on tensimeter and the computing machine; Also can select the different model of this device according to the range of bunker scale, general single only digital LOAD CELLS measurement range selection scope is 2t～100t, is 5t～400t (containing the hopper deadweight) by verification bunker scale LOAD CELLS range.When carrying out the linear verification of bunker scale, can progressively pressurize to system from zero point, and segmentation adjusts until full scale, when returning inspection, progressively reduce pressure by hydraulic valve control and advance to operate.After the verification of finishing a bunker scale, can disassemble easily to be installed to fast on another bunker scale to be measured and carry out verification.
