The utility device is a convenient, fast and accurate hopper scale calibration device, which is convenient for dismantling and mounting; after finishing the detection of one hopper scale, the device can be arranged to another hopper scale to be detected after dismantling; the whole calibration process of one hopper scale can be finished within 15 minutes.
Description
Technical field
The utility model discloses a kind of calibration equipment of metallurgical system batching bunker scale, belong to the Measuring and testing technical field.
Background technology
Before the utility model is made, can't carry out verification to the large-tonnage bunker scale, even the verification of little tonnage also needs to adopt traditional counterweight method of calibration, this classic method is in the loading and unloading of counterweight, adjustment process, expended great amount of manpower and material resources and time, the verification of general every platform balance needs 2-3 hour.And bunker scale examine and determine for the first time put into operation after,, effort loaded down with trivial details, time-consuming because of checking procedure, formed contradiction with the rhythm of production of anxiety, substantially no longer carry out verification, through operation for a long time, can't guarantee the measuring accuracy of bunker scale, produce bigger influence for controlling of production process and producting cost accounting.
Summary of the invention
The purpose of this utility model is to provide a kind of bunker scale easy, verification bunker scale weighing precision fast and accurately quick calibration equipment into adapting to the verification needs of bunker scale.Its installation for convenience detach, after the calibrating of finishing a bunker scale, the dismounting decomposition can be installed other one rapidly and be treated the school bunker scale, just can finish the complete verification process of a bunker scale in 15 minutes.
The purpose of this utility model can reach by following measure: hydraulic pump replaces the gravity of counterweight as the stressed source of system; Stressed lifting jack is exerted pressure to standard transducer with by check sensor simultaneously synchronously.
The purpose of this utility model can also be come perfect by following measure: in the connection and pressure transmitting portions of bunker scale calibration equipment, and verification pedestal and basic built-in fitting firm welding, the stability under loading of maintenance system; Pressure boost carrier, vertical pull bar keep stressed unanimity; Increase by check sensor locate top base, standard transducer triadius type bottom base make install easy to connect; Hydraulic pump increases blowout-back pressure gauge, is convenient to recording geometry pressure changing condition; The application of hydraulic pressure trapped line pressure valve can keep system pressure for a long time.
Structure of the present utility model is such: the quick calibration equipment of a kind of bunker scale, it is characterized in that constituting rigid frame, lay by check sensor between verification pedestal and the pressure carrier from bottom to top successively, constituted by check sensor location top base, standard transducer triadius type bottom base, lifting jack, standard transducer by vertical pull bar and pressure carrier that verification pedestal both sides connect.
Lifting jack is connected with hydraulic pump through high-pressure oil pipe, distribution valve during work, and signal cable connects sensor and Displaying Meter.Be stability and the security of guaranteeing system; system has adopted triadius type sensor bottom base and has been combined by check sensor location top base; guarantee stressed vertical stable; the vertical pull bar of pressure carrier is as the vertical spacing lateral stressed stable protective effect of having played; the pre-buried processing of verification pedestal; the system that makes has had enough tension intensitys, and structure can not rupture when guaranteeing system's pressurization.The selection of synchronous jack stroke has taken into full account the deformation quantity of sensor and verification structure, makes structure more firm.
The principle of work of the utility model each several part is as follows.When carrying out the calibration of bunker scale, at first the weighing instrument to bunker scale carries out the adjustment at zero point, and promptly check for zero carries out zero setting to check meter then, can begin range check after balance check is finished.The reverse checkvalve that earlier Hydraulic Station pump (J) dammed is closed, pressurize to system, hydraulic oil is exerted pressure to (several) lifting jack (C) simultaneously by high-pressure oil pipe, the cylinder body of lifting jack rises under hydraulic action, pressure is passed to the standard transducer (D) that is positioned at the lifting jack top, standard transducer passes to system pressure the pressure carrier again, and act on the verification pedestal by the vertical pull bar of carrier both sides, produce pressure vertically downward, be subjected to the identical pressure of size simultaneously by verification (bunker scale) sensor, and maintenance system equalization of pressure, the output signal of bunker scale check sensor is thereto respectively, by a bus system signal is sent into the verification Displaying Meter, the standard value (gravimetric value that is equivalent to counterweight) that shows current system pressure by the test check meter, the video data of bunker scale weighing instrument and this standard value compare, analyze, confirm to demarcate and parameter modification the bunker scale weighing instrument after load has reached full scale.Hydraulic system is when the needs drain charge, and the reverse checkvalve that dams that can directly open Hydraulic Station carries out drain charge, and under the effect of system's deadweight, the automatic back pressure of hydraulic system is promptly got back to zero point.
When bunker scale adopts the hydraulic system calibration, should at first be forced into full scale, and observe the video data of tensimeter and check meter, and make it to be no more than the load capacity of bunker scale sensor, after stablizing, full scale and video data can carry out range check confirming to reach.When carrying out the linear verification of bunker scale, can begin pressurization from zero point to system, according to " measurement verification regulations " system pressure is added to 25%, 50%, 75%, 100% of full scale fully, and adjust accordingly.In the inspection process of returning of bunker scale, the reverse checkvalve that dams of Hydraulic Station slowly can be opened, be treated to adjust after system pressure is slowly reduced to goal pressure, equally 100%, 75%, 50%, 25%, 0 operating according to " measurement verification regulations ".
The utility model has the advantages that a kind of easy, bunker scale calibration equipment fast and accurately.Its installation for convenience detach, after the calibrating of finishing a bunker scale, dismounting is decomposed can be installed to an other bunker scale to be measured rapidly, just can finish the complete verification process of a bunker scale in 15 minutes.
