Description
Technical field
The utility model relates to the real coal calibration equipment on a kind of bridge-type machine for unloading coal, belongs to bridge-type machine for unloading coal weighing technology field.
Background technology
After coal carrier arrives power plant, with the bridge-type machine for unloading coal coal is delivered on the belt conveyor and by belted electronic balance and to be carried out dynamic weighing, be delivered to coal yard, with claim general assembly (TW) as settling accounts foundation, so the weighing precision of belted electronic balance is very important.According to working specification, tackle belted electronic balance at regular intervals and calibrate, so that it is carried out correct demarcation.Calibration steps commonly used has: calibration of weight method, rolling code calibration method and material calibration method in kind.Material calibration method wherein in kind is again kinetic measurement because of relatively meeting the belted electronic balance actual operating mode, because of the precision height, is the calibration steps of using always at present.Material calibration method in kind is that a hopper in kind is set in the front portion of belted electronic balance, and hopper in kind is fixed on several LOAD CELLS and forms a static bunker scale.The material object material that this static state bunker scale is weighed up is applied on the belt conveyor by hopper, comes the correcting electronic belt conveyer scale in conjunction with the real-world operation parameter.For guaranteeing the belted electronic balance precision, dynamic similation amount in trimming process is very big, the verification amount of general power plant admission coal is 40 tons, the verification amount of going into the stove coal is 24～32 tons, because do not consider admission coal calibrating installation in the large power plant design at present, big like this bunker scale almost can't be installed at the scene.
CN2101221U disclosed " a kind of device that belted electronic balance is carried out physical goods inspection ", proposed to improve the excessive problem of materials amount in the actual material calibration, be in whole device, to increase the circulation feed mechanism, will collect by the material object material of belted electronic balance force rod at every turn, again deliver among the hopper in kind, to satisfy in the verification, dwindle the volume of hopper in kind to the requirement of flow.But there is following defective in the device of the physical goods inspection of this structure: 1, owing to will increase mechanisms such as a cover circulation material loading, hopper in kind in addition above belt conveyer scale, make that the device of whole physical goods inspection is more complicated.2, owing to adopt circulation material loading, specified Weighing method repeatedly, complex structure, and repeatedly weigh and can produce cumulative errors, consequent cumulative errors make weighing precision descend again.3, hopper is difficult to accurate control after the rated weight that collection reaches.4, owing to need not only influence normal loading and unloading, and increase management and use cost with special irony material as the object simulating material, operability is not strong.
Summary of the invention
The purpose of this utility model provides a kind of simple and reasonable for structure, and verification operation is the real coal calibration equipment on the bridge-type machine for unloading coal easily.
The utility model is that the technical scheme that achieves the above object is: the real coal calibration equipment on a kind of bridge-type machine for unloading coal, it is characterized in that: comprise coal bunker, bridge machine frame beam and LOAD CELLS, at least be symmetrically fixed with the stationary positioned piece that is used to be bearing in the coal bunker roof side rail more than two on the described bridge machine frame beam, at least two LOAD CELLS are installed on the bridge machine frame beam, and the loading end on LOAD CELLS top is equipped with the axially movable bearing part of energy, the roof side rail bottom of the corresponding coal bunker of bearing part, the outside of coal bunker also is symmetrically installed with hoisting mechanism.
The utility model improves hopper on the bridge-type machine for unloading coal and bridge machine frame beam, only on bridge machine frame beam, stationary positioned piece and LOAD CELLS have been increased, coal bunker loading and unloading normally, and coal bunker and LOAD CELLS can be formed a static bunker scale again, simple and reasonable for structure, when need carry out verification to belted electronic balance, only need to be installed in the bearing part rising jack-up coal bunker on LOAD CELLS top, the coal bunker of filling behind the material is weighed, be discharged to belted electronic balance again and calibrate.The utility model adopts existing coal bunker that coal in kind is carried out weighing, and enough capacity are not only arranged, and also meets admission coal verification requirement, has saved the verification cost.The utility model need not to take up room owing to need not increase other device, to not at all influence of site work.The utility model can carry out verification to belted electronic balance at any time in the process of unloading coal, correct operation is convenient, and a weighing of energy, and weighing precision is only related with the precision of LOAD CELLS, solve repeatedly specified weighing and caused cumulative errors, helped the raising of checking precision.
