Abstract
The utility model discloses a weigher body unit capable of off-line calibrating a belt weigher, belonging to a weigher body device of an electronic belt weigher. The weigher body unit comprises a driving device, a supporting roller, a rectangular frame-type rigid bearing base and a set of calibration tool, wherein the rectangular frame-type rigid bearing base is arranged below the supporting roller; the rigid bearing base is symmetrically provided with four weighing sensors and four sensor installing modules corresponding to the weighing sensors; the calibration tool consists of a calibrationweight, a calibration frame and a movable push-pull rod; the calibration weight is arranged on the rigid bearing base through the weight calibration frame; the other end of the weight calibration frame is also connected with the other end of the weighing sensor; an induction sensor is also arranged below the calibration weight; and a weight support frame is fixed with the rigid bearing base. The weigher body unit has the advantages that the problem of installation and calibration of the belt weigher is well solved through the off-line static calibration and on-line automatic loading and calibration, the on-line automatic loading and calibration is implemented under the condition of not terminating the normal operation, and the weigher body unit is particularly applicable to the requirements of on-line dynamic calibration.
Description
Technical field
The utility model relates to a kind of belted electronic balance and claims body unit, but specifically is that a kind of off-line calibration belt conveyer scale claims body unit, realizes the device of high-precision measuring by off-line static calibration and on-line automatic loading dynamic calibration.
Background technology
Existing belted electronic balance can not satisfy the demand of client to the high-precision electronic belt conveyer scale far away on measuring accuracy, belted electronic balance in use, owing to be subjected to that belted electronic balance is installed and the level of initial calibration, claim the influence of various factorss such as sideslip that the anti-material of body is setovered ability, belt and follow-up maintenance to make belt conveyer scale on measuring accuracy, be difficult to reach a higher level.
Summary of the invention
For solving the problems of the technologies described above, but the utility model provides a kind of off-line calibration belt conveyer scale to claim body unit.Can be when dispatching from the factory and carry out the static calibration and the overload protection debugging of off-line during maintenance, can be under running status to belt conveyer scale load the on-line proving verification automatically, the stable blocking of implementing high-precision measuring claims body device.
The utility model is realized by following technical scheme: but a kind of off-line calibration belt conveyer scale claims body unit, it is characterized in that comprising drive unit, carrying roller, be installed in the rectangle frame posture rigidity load-bearing pedestal below the carrying roller, on rigidity load-bearing pedestal, be symmetrically installed with four LOAD CELLS and with corresponding four the sensor installed modules of LOAD CELLS, an and cover verification cubing; The verification cubing is made up of verification counterweight, verification frame and removable pull bar, the verification counterweight is installed on the rigidity load-bearing pedestal by counterweight verification frame, the other end of counterweight verification frame also is connected with the other end of LOAD CELLS, induction pick-up also is installed below the verification counterweight, and counterweight bracing frame and rigidity load-bearing pedestal are fixed together.
The said units weighing device can be selected one group, two or more sets blocking weighing devices for use by precision, erecting stage condition, constitutes the complete weighing system of a cover.Weigh the verification counterweight under the driving of drive unit, form the parallel misalignment structure by counterweight verification frame, counterweight bracing frame, automatically load or unload verification counterweight.
The beneficial effects of the utility model are: belted electronic balance claims body to adopt cellular structure, can demarcate the difficulty that preferably resolves the belt conveyer scale installation calibrating by off-line static calibration and on-line automatic loading, it is to implement under the condition of not ending normal operation that on-line automatic loading is demarcated, and adapts to the needs of dynamic on-line proving especially.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1;
Fig. 4 is the A-A sectional view of Fig. 1.
Among the figure: 1, drive unit, 2, carrying roller, 3, the load-bearing pedestal, 4, LOAD CELLS, 5, the verification chain code of weighing, 6, induction pick-up, 7, the counterweight bracing frame, 8, counterweight verification frame, 9, roller rack, 10, mobile pull bar, 11, the LOAD CELLS installed module.
Embodiment
As Fig. 1-shown in Figure 4, drive unit 1, carrying roller 2, be installed in the rectangle frame posture rigidity load-bearing pedestal 3 below the carrying roller, four groups of LOAD CELLS 4 that symmetry is installed on rigidity load-bearing pedestal 3 and with the corresponding four groups of LOAD CELLS installed modules 11 of LOAD CELLS, and a cover verification cubing is formed a weighing unit.The verification cubing is made up of verification counterweight 5, verification frame 8 and removable pull bar 10; Carrying roller 2 is installed on the roller rack 9.Verification counterweight 5 is installed on the rigidity load-bearing pedestal 3 by counterweight verification frame 8, the other end of counterweight verification frame 8 also is connected with the other end of LOAD CELLS 4, induction pick-up 6 also is installed below verification counterweight 5, and counterweight bracing frame 7 and rigidity load-bearing pedestal 3 are fixed together.Weigh the verification counterweight under the driving of drive unit 1, form the parallel misalignment structure by counterweight verification frame 8, counterweight bracing frame 7, automatically load or unload verification counterweight.Can when emat sensor more, carry out the adjustment of overload protection arrangement, but also the symmetric body device carries out the calibrate of off-line.Weighing system can be selected one group, two or more sets blocking weighing devices for use by precision, erecting stage condition, constitutes the complete weighing system of a cover.
