Abstract
The invention provides an angle change weight compensator for a stacker-reclaimer belt scale, belonging to the design and manufacture technical field of the angle change weight compensator for a stacker-reclaimer belt scale. The upper side of a base is provided with two sensors: a sensor A and a sensor B; the base between the two sensors is provided with an angle sensor. The angle change weight compensator for a stacker-reclaimer belt scale is used in connection with an electronic belt scale. When materials pass through a belt, a carrying roller is under pressure, the pressure is transferred to a bearing plate through a carrying roller support, and the pressure born by the bearing plate is transferred to weighing sensors symmetrically arranged. According to the theoretical mechanics bearing analysis principle and the sensor inner strain gage graetz connection principle, the up and down force points and key points change with the changing of a force transmission point which is influenced by angle change; the weighing sensors are symmetrically arranged to form a change of ''the up is less and the lower is more'' or ''the up is more and the lower is less'' so as to be relatively complemented and to realize minimum difference change of resultant force; the angle sensor is used for performing accurate angle change compensation to the error with minimum difference so as to make the electronic belt scale accurately weigh cargos. The angle change weight compensator for a stacker-reclaimer belt scale solves the problem of large metering precision error of an existing stacker-reclaimer belt scale.
Description
Technical field
The utility model belongs to the stacker-reclaimer belt conveyer scale changes the weight compensating device with angle design and manufacturing technology field.
Background technology
At present AT STATION, the band conveyor of the stacker-reclaimer that harbour and stock ground, mine the are used angle of conveying belt at work can change at any time, when angle changes, zero point on the belt conveyer scale, range also can change thereupon, this variation makes the error of measuring accuracy more than 10%, seriously influences measuring accuracy.And national regulation is 0.3～0.5% for the error of measuring accuracy standard.Brought very big economic loss for for a long time user and client, from the existing metering outfit of present band conveyor, the function that does not also possess weight compensating, thereby can't fundamentally solve owing to belt feeder is in service because angle changes the error problem of bringing greatly.
Summary of the invention
At last narration situation, the purpose of this utility model provides a kind of angle by theoretical mechanics force analysis principle design and changes the weight compensating device, to solve the big problem of error in dipping that existing equipment exists.Maintenance customer and client's legitimate rights and interests.
The utility model is to address the above problem the technical scheme of being taked to be: be made of roller rack and weighing unit.Left side of face has the A sensor on base, has the B sensor on the right side of base.On sensor, have force transmitting board, on the base between the two sensors, have angular transducer.Two sensors of A, B are provided with in the angular transducer symmetria bilateralis.Force transmitting board by bolted on connection on roller rack.Sensor by bolted on connection on power transmission bolt plate.
Use of the present utility model is that it is installed on the belt feeder of stacker-reclaimer, links to each other with belted electronic balance.When material passed through belt, following carrying roller was under pressure, and through roller rack the pressure that is subjected to is delivered to stressed plate, and the suffered power of stressed plate passes to again on the symmetrically arranged LOAD CELLS.According to theoretical mechanics force analysis principle and sensor internal foil gauge bridge-type catenation principle, when the power transmission point is subjected to the angle variable effect, force, emphasis also change thereupon up and down, because LOAD CELLS becomes symmetric form to arrange, promptly form the variation of " going up few many down " or " going up how few down ", thus complementary, realize that the difference in change heteropole is little with joint efforts, by angular transducer, the error that difference is very little is carried out angle compensating for variations accurately more again, make the weight of the accurate weighing goods of belted electronic balance.Thereby guaranteed measuring accuracy, solved the big problem of existing stacker-reclaimer belt conveyer scale measuring accuracy error.
