Abstract
A hopper electronic scale calibration device utilizing a dynamometer and a jack relates to calibration of various hopper electronic scales and is characterized by being composed of a lower support, the jack, a standard dynamometer and an upper support. The lower support is of an n-shaped steel plate structure with an opening downwards, and the lower edge face of the lower support corresponds to the outer edge face of the upper end face of the hopper electronic scale. The upper support is of an n-shaped steel plate structure with an opening upwards, and the upper edge face of the upper support corresponds to the lower edge face of a feeding pipe above the hopper electronic scale. The lower support is placed on the upper end face of the hopper electronic scale, the jack, the standard dynamometer and the upper support are arranged on the upper surface of the lower support sequentially from bottom to top, and the upper edge face of the upper support faces the lower edge face of the feeding pipe. The hopper electronic scale calibration device has the advantages of being high in scale calibration speed, low in labor intensity, high in calibration accuracy and is provided with a high furnace groove.
Description
Technical field:
The utility model relates to the verification of various hopper electronic scaless, particularly utilizes dynamometer to add the hopper electronic scales calibration equipment of lifting jack.
Background technology:
Hopper electronic scales of former check need send 4 porters to add 2 instrument workers, with one by one heavily for the standard test weight of 20kg toward being put in the hopper electronic scales of school till the 500kg.See bunker scale weight whether in the permissible error scope, if defective will counterweight being taken out of carried out the electronic scales correction, standard test weight again that 20kg is heavy after the correction is moved on the hopper electronic scales, sees that gravimetric value that bunker scale shows is whether in the permissible error scope.Above-mentioned steps proceeds to till the electronic scales calibration repeatedly.There is more problem in this electronic scales check addition: one of which, and check a needed time of electronic scales long.Its two, the workload of removing counterweight is big.Its three, can cause the phenomenon that bigger linearity is poor, accuracy is low, error is big with the electronic scales of 500kg counterweight verification load 4-10 ton.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, and a kind of hopper electronic scales calibration equipment that utilizes dynamometer to add lifting jack is provided.
The scheme of the utility model is: it is characterized in that: device is made up of lower carriage, lifting jack, standard force-measuring meter, upper bracket; Lower carriage is downward opening " door " Zee bar steel Z plate structure; Lower carriage lower edge face is corresponding to outer, hopper electronic scales upper surface face; Upper bracket is opening " door " Zee bar steel Z plate structure up, and upper bracket upper edge face is corresponding to the tremie pipe lower edge face of hopper electronic scales top; Lower carriage is placed on hopper electronic scales upper surface, places lifting jack, standard force-measuring meter, upper bracket from bottom to top successively at the lower carriage upper surface, the upper bracket upper edge is facing to tremie pipe lower edge face.
The advantage of the utility model is: the blast furnace groove hopper electronic scales that a kind of school scale speed is fast, labour intensity is low, checking precision is high calibration equipment is provided.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
The utility model is characterized in that: device is made up of lower carriage 3, lifting jack 4, standard force-measuring meter 5, upper bracket 6; Lower carriage 3 is downward opening " door " Zee bar steel Z plate structure; Lower carriage 3 lower edge faces are corresponding to outer, hopper electronic scales 2 upper surface face; Upper bracket 6 is opening " door " Zee bar steel Z plate structure up, and upper bracket 6 upper edge faces are corresponding to the tremie pipe 7 lower edge faces of hopper electronic scales 2 tops; Lower carriage 3 is placed on hopper electronic scales 2 upper surfaces, places lifting jack 4, standard force-measuring meter 5, upper bracket 6 from bottom to top successively at lower carriage 3 upper surfaces, upper bracket 6 upper edges are facing to tremie pipe 7 lower edge faces.
At upper bracket 6 when tremie pipe 7 under the blast furnace groove does not contact; The zero-bit of elder generation's calibration criterion dynamometer 5; Whether then lifting jack 4 rises upper bracket 6 contact with tremie pipe 7, reads standard dynamometer 5 and hopper electronic scales 2 reading through weighing sensor 1 demonstration and compares, look in the permissible error scope and regulate; Make lifting jack 4 increase the weight of to carry step by step, the error under the detection Different Weight level is also regulated.
