Description

Weighing module
Technical field
The utility model relates to a kind of Weighing module that is used for electronic weighing system, belongs to the electronic scale technical field.
Background technology
In industries such as cement, metallurgy, chemical industry, grain processing, petrochemical industry, metering method of weighing commonly used is counted heavy to material or material level is controlled.Be that a plurality of Weighing mechanisms are installed in batch can bottom or middle part when weighing, the weight or the material level of material in the automatic gauge batch can; Or the some feets in a plurality of feets of supporting batch can or a plurality of feets place be equipped with Weighing mechanism to batch can in the weight or the material level of material measure.For ease of integral installation, simple to reach installation, convenient debugging, maintenance, Weighing mechanism adopts a plurality of Weighing module structures, each Weighing module is formed an independently one-piece construction by two anti-bolts that topple with base plate, coupling assembling, last pressure part, following pressure part and pillar LOAD CELLS, by being provided with spacing between fixed head or support plate and the base plate, and also be provided with spacing between the shaft shoulder of the anti-bolt that topples and the fixed head, can be in unsteady state when making the work of pillar LOAD CELLS, can not influence the precision of metering.Simultaneously be subjected to wind-force in the weighing system surrounding environment, disturbing factor such as air-flow and vibration, or Weighing module is when being subjected to overloading, may produce in the pillar LOAD CELLS under the fortuitous events such as cracked or damage, fixed head or support plate on the coupling assembling are contacted with base plate, the vertical force that coupling assembling bore is acted directly on the base plate, and when weighing system is subjected to the external impacts power of level, contact with following pressure part by fixed head, the horizontal force that coupling assembling bore is delivered to the installation base plate, to guarantee the safety of Weighing module, has the weighing precision height, working stability, the characteristics of anti-advantage of toppling.But the coupling assembling of this structure is because top board, support plate and fixed head formation, top board is provided with pilot hole, upper and lower bearing part is installed in the last pilot hole of top board and the spacing hole on the fixed head respectively, and the pillar LOAD CELLS is installed in pressure part and following pressure part, the structure relative complex, especially must adopt column type sensor, make that also manufacturing cost is higher.But because the installation basis of LOAD CELLS can not remain on the same surface level, the installed surface that always has one or several LOAD CELLS is below or above reference field, in this case, every suffered vertical force of LOAD CELLS is all different, may cause certain sensor stressed excessive and damage, a lot of batch cans need to stir in the course of the work, stirring can cause batch can to rock, cause security incident too greatly for avoiding rocking, the spacing displacement of rocking that limits batch can of meeting design level, after the spacing size installation of level, just can't adjust once more, after batch can work a period of time, because equipment load metamorphism and foundation settlement distortion cause the spacing gap smaller of level until stuck, finally cause weighing precision inaccurate.Moreover, be mounted in because of some batch can on the inclined-plane at certain inclination angle, in this case, LOAD CELLS not only is subjected to vertical force, also is subjected to the effect of horizontal force, some batch cans are installed in outdoor in addition, Weighing module is installed in the batch can bottom, and under wind load and seismic (seismal effect, batch can easily topples, for avoiding batch can to topple, need to consider the anti-structure of toppling.A lot of batch cans are installed and are subjected to space constraint; must sling weighing; and pull-type sensor is ruptured under extreme case by pulling force easily; cause batch can from falling in the air; very easily cause the accident; do not have good solution at present, can only do the physical construction protection, and increase the complicacy that Weighing module is installed.
Summary of the invention
The purpose of this utility model provides a kind of weighing precision height, safe and reliable, installation and maintenance convenience, working stability, the Weighing module of low cost of manufacture.
The utility model is that the technical scheme that achieves the above object is: a kind of Weighing module, comprise base and LOAD CELLS, LOAD CELLS connects side and is installed on the base by securing member, base is provided with plural mounting hole, it is characterized in that: described base is provided with limited impression, and the two sides of LOAD CELLS and the cell wall of limited impression join; The load side of described LOAD CELLS vertically is provided with blind hole, the top board of frame is or/and base plate is provided with mounting hole, the bearing part that the bottom is provided with spacing hole is screwed on the top board of frame, and bearing part is fixed by locking member and top board, shake in the spacing hole that the post both sides are separately positioned on the blind hole of LOAD CELLS and bearing part, and the both ends of the surface of shaking post contact with the bottom surface of blind hole and the end face sphere of spacing hole respectively, and the upper surface of LOAD CELLS has vertical guard band A with the bearing part bottom surface; Two horizontal caging bolts are installed on the biside plate respectively and are positioned at the both sides of LOAD CELLS, and the two sides of horizontal caging bolt end face and LOAD CELLS are provided with horizontal guard band B.
