After oil drum folder is embraced and is promoted by the scale of falling bucket, the upset or stop action that are greater than 180 degree can be done aloft, and oil drum can be loaded and unloaded on automobile, stacking, therefore carrying and the weighing process of chemical plant oil drum is widely used in, not only alleviate the operation of manpower oil barrel conveyor, also substantially increase the production efficiency of factory and efficiency of weighing.
Existing LOAD CELLS in use, LOAD CELLS is connected up and down with oil drum, its structure principle chart as shown in Figure 1, sensor a lower left is connected with the car body b of the scale of falling bucket, upper right side and the oil drum of sensor a are embraced clamp device c and are connected, when embracing folder oil drum, sensor a is by right side oil drum Action of Gravity Field, there is deformation in the looping pit d at sensor a center, owing to connecting up and down, cause sensor a stressed asymmetric, there is comparatively large deformation in looping pit d, also there is comparatively large deformation in the resistance strain gage be positioned at above looping pit d thereupon, exceed foil gauge generation deformation range, cause measurement inaccurate, even foil gauge is caused damage.In order to bear oil drum gravity, traditional scale of falling bucket adopts dual sensor to replace single-sensor, and dual sensor, due to signal disturbing, brings data transmission problems, affects the accuracy of weighing.
Summary of the invention
In order to solve the problems of the prior art, it is simple that the purpose of this utility model is to provide a kind of structure, LOAD CELLS easy for installation; LOAD CELLS of the present utility model is in the scale of falling bucket use procedure, oil drum is placed in sensor front, connected mode before and after sensor and oil drum adopt, reduce oil drum applying acting force on a sensor, only need use a sensor, simplify installation steps, avoid the data transmission problems that dual sensor brings simultaneously, improve the accuracy of measurement.
The technical solution of the utility model: a kind of LOAD CELLS, it is characterized in that, comprise housing and the mounting hole being arranged on housing both sides, described mounting hole is connected with the car body of the scale of falling bucket and oil drum respectively, two U-lags are symmetrically arranged with above described housing, one groove is set between described U-lag, two inverted U-shaped holes are symmetrically arranged with below described housing, a boss is provided with between described inverted U-shaped hole, weight induction chip is separately installed with in described groove and boss, described induction chip is connected with signal wire, described signal wire stretches out sensor housing.
Wherein, described mounting hole is 8.
Wherein, described mounting hole is fixedly connected with oil drum with the car body of the scale of falling bucket respectively by M16 bolt.
Wherein, described U-lag and inverted U-shaped hole are Mirror Symmetry distribution.
Wherein, described groove and boss are Mirror Symmetry distribution.
Wherein, described mounting hole is connected with inverted U-shaped hole with U-lag.
Wherein, described casing center position is provided with looping pit.
Wherein, described sensor is alloy steel material.
Compared with prior art, the beneficial effect that the utility model realizes: LOAD CELLS of the present utility model arranges mounting hole in housing both sides, being fixedly connected with of sensor and oil drum is completed by M16 bolt, LOAD CELLS and the mode that connects before and after oil drum, reduce oil drum applying acting force on a sensor, only a sensor need be used to complete function of weighing; LOAD CELLS of the present utility model replaces dual sensor with single-sensor, easy for installation, avoids the data transmission problems that dual sensor brings simultaneously, weighs more accurate.
