Description
Technical field
The present invention relates to a kind of hinge type storage tank Weighing device, solve inaccurate and that weighing-appliance cost the is high problem of weighing that existing storage tank weighing technology exists.
Background technology
Traditional tank weights is all measured by radar, ultrasonic technology, but there is the inaccurate intrinsic problem of measurement caused for solid material air spots, dust etc. in radar, ultrasound wave etc., therefore weighing level indicator is widely used in the thing position observing and controlling of modern metallurgy industry, progressively instead of radar and ultrasonic material level detection unit.Weighing level indicator again based on four sensors with the use of, but also there is larger problem in this structure, for heavy weight storage tank, single LOAD CELLS price is all very expensive, if entirely join and virtually add input cost, the increase in number of sensors also can with the instability of incoming telephone signal.
In order to accelerate China's tank measurements to the automation direction speed of development, Study and Development low cost, high-precision storage tank automatic metering system are very important.This technology has done certain research and development to the communication protocol of storage tank automatic gauge, the metering method of storage tank.
Summary of the invention
The object of this invention is to provide a kind of hinge type storage tank Weighing device, overcome the defect that above-mentioned prior art exists.
Technical scheme of the present invention is achieved in the following ways:
The present invention includes vertical storage tank, supporting leg, base, LOAD CELLS, hinge, terminal box, weight transmitter, PLC and computing machine, it is characterized in that being provided with four supporting legs in vertical storage tank bottom even ground correspondence, article four, supporting leg is sitting on the base of level, two legs is provided with symmetrical LOAD CELLS, two other leg is provided with symmetrical hinge, in correspondence with each other, and the overall height of four supporting legs is equal for the supporting leg being provided with LOAD CELLS and the supporting leg being provided with hinge; The signal wire of LOAD CELLS is connected by terminal box and weight transmitter, and weight transmitter and PLC are connected, and PLC and computing machine are connected; The Action of Gravity Field of vertical storage tank and carrier is in LOAD CELLS, LOAD CELLS output voltage signal passes to weight transmitter display quality signal, and the standard signal being converted into 4-20mA passes to PLC process, process data are passed to computing machine by PLC, and computer monitoring and display print carrying general assembly (TW) and the vehicle weight of vertical storage tank.
Supporting leg is set to cylindrical, forms by two sections, is provided with LOAD CELLS or hinge between two ends.
Hinge comprises upper conical seat, inferior pyramidal seat and roller, upper conical seat is relative with inferior pyramidal seat microcephaly, a half-arc groove is provided with separately in the front and back of little centriciput, two half-arc groove symmetries, roller is provided with between two half-arc grooves, upper conical seat is in supporting leg epimere lower end vertical welding, and inferior pyramidal seat is fixed on base.
Compared with the prior art the present invention has the following advantages:
1, structure of the present invention simple, be quick on the draw, weighing precision is high, accurately can measure the quality of raw material turnover tank.
2, utilize hinging manner to decrease the number of LOAD CELLS, improve storage tank stable dangerous with wind resistance, saved implementation cost, weighed for the carrier in large-scale storage tank and create a Tiao Xin road.

Embodiment
For disclosing technical scheme of the present invention further, elaborated by embodiment below in conjunction with Figure of description:
The present invention includes vertical storage tank 1, supporting leg 2, base 5, LOAD CELLS 3, hinge 4, terminal box, weight transmitter, PLC and computing machine, it is characterized in that being provided with four supporting legs 2 in vertical storage tank 1 bottom even ground correspondence, article four, supporting leg 2 is sitting on the base 5 of level, two legs is provided with symmetrical LOAD CELLS 3, two other leg is provided with symmetrical hinge 4, be provided with the supporting leg of LOAD CELLS 3 and be provided with the supporting leg of hinge 4 in correspondence with each other, and the overall height of four supporting legs is equal; The signal wire of LOAD CELLS 3 is connected by terminal box and weight transmitter, and weight transmitter and PLC are connected, and PLC and computing machine are connected; The Action of Gravity Field of vertical storage tank 1 and carrier is in LOAD CELLS 3, LOAD CELLS 3 output voltage signal passes to weight transmitter display quality signal, and the standard signal being converted into 4-20mA passes to PLC process, process data are passed to computing machine by PLC, and computer monitoring and display print carrying general assembly (TW) and the vehicle weight of vertical storage tank.
1, principle of work of the present invention and working routine
The Action of Gravity Field of vertical storage tank is in LOAD CELLS, and sensor elastomer stress deformation, interior patches resistance changes, output voltage signal, and this voltage signal is directly proportional to stressed size, and this signal is less, greatly about 0 ~ 30mV once.Little mV signal while display weight, then amplifies and is converted into 4 ~ 20mA standard signal by weight transmitter, and pass to PLC process, last PLC is uploaded to computer processing system process.Computer processing system is the software systems according to need of work secondary development, and this system can the weight of on line real-time monitoring vertical storage tank.
2, the demarcation of weight transmitter
The present invention adopt be can in case counterweight demarcate weight transmitter, calibration process in two steps:
1) with reference to the instructions of transmitter to adjust the zero point of transmitter, the parameter such as capacity, sensitivity, title body strong point number, nonsupport point number of capacity sensor unit, single-sensor exempts from counterweight demarcation;
2) instructions with reference to weight transmitter adds counterweight demarcation to weight transmitter, also can be described as loading and demarcates.
