Description
Technical Field
The present invention relates to a structure for loading a force sensor on a column for measuring the weight of an object supported by the column.
Background
The large storage bin or the large storage tank has no method for accurately measuring the weight of the large storage bin or the large storage tank due to the difficulties and potential safety hazards of the field installation of the sensor.
In order to be able to measure the weight of a large storage silo or a large storage tank, the prior art means use the following two ways:
the first mode is as follows: a weighing module is added below a supporting upright post used for supporting a large storage silo or a large storage tank. Although the weighing module can accurately measure the weight of a large storage bin or a large storage tank, the supporting upright for installing the weighing module is usually disconnected from the foundation, so that the measuring mode has potential safety hazards.
The second mode is as follows: and a module with a strain gauge attached or welded to a support column for supporting a large storage bin or a large storage tank. The measurement mode does not change the supporting structure of the original large storage bin or large storage tank, but the measurement precision of the measurement mode is not high due to the fact that the strain of the supporting upright post after being stressed is too small (often, only dozens of micro strain).
Disclosure of Invention
The purpose of the invention is: the accurate measurement of the weight of the object is realized on the premise of not damaging the supporting structure of the object.
In order to achieve the above object, the present invention provides a pillar loading force sensor structure, wherein a direction of a support pillar is defined as a length direction, and the pillar loading force sensor structure includes:
the strain conduction part is fixedly connected with the support upright post, a first fixed connection point and a second fixed connection point are arranged between the strain conduction part and the support upright post, and after the support upright post is stressed, the strain conduction part conducts strain to a deformation area of a part, with the length of L, of the support upright post, which is positioned between the first fixed connection point and the second fixed connection point;
the length of the deformation area is h, h is less than L, the strain conduction part conducts the strain of the support column to the deformation area, the deformation area is enabled to change synchronously along with the part, with the length of L, of the support column, and then the strain of the support column is equivalently amplified by K times, wherein the K is L/h;
and the force sensor is used for detecting the strain of the deformation area and converting the measured force into an electric signal to be output.
Preferably, the strain conducting portion includes a first fixing member and a second fixing member, one ends of the first fixing member and the second fixing member are fixed on the support column, and the distance between the first fixing member and the second fixing member is L; and a first conduction rod and a second conduction rod which are parallel to the support column are respectively arranged at the other ends of the first fixing piece and the second fixing piece, the shapes and the sizes of the first conduction rod and the second conduction rod are always kept unchanged, and the deformation region is formed between the first conduction rod and the second conduction rod.
Preferably, the force sensor is a strain foil attached to the deformation zone.
The column loading force sensor structure provided by the invention can equivalently expand the original tiny deformation of the support column by K times and then carry out measurement, thereby improving the measurement precision. Meanwhile, the original structure of the supporting upright post is not required to be damaged, and potential safety hazards are avoided.
Drawings
Fig. 1 is a schematic structural diagram of a structure of a pillar loading force sensor disclosed in this embodiment;
fig. 2 shows the application of the structure shown in fig. 1 to a large storage silo or a large storage tank.
Detailed Description
The invention is further illustrated by the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
As shown in fig. 1, the pillar loading force sensor structure disclosed in this embodiment includes a first fixing member 2-1 and a second fixing member 2-2, where the first fixing member 2-1 and the second fixing member 2-2 are installed on a supporting pillar 1 for supporting an object, and a distance between the first fixing member 2-1 and the second fixing member 2-2 along a direction in which the supporting pillar 1 is located is L. The tail ends of the first conducting rod 3-1 and the second conducting rod 3-1 which are parallel to the supporting upright column 1 are respectively fixed on the first fixing piece 2-1 and the second fixing piece 2-2. A deformation area 4 is formed between the first conductive rod 3-1 and the top end of the second conductive rod 3-1. The length direction of the supporting upright post 1 is defined as the length direction, then the length of the deformation zone 4 is h, and h & lt L. The first conductive rod 3-1 and the second conductive rod 3-1 always keep the shape and the size unchanged. After the supporting upright post 1 is stressed and deformed, the deformation quantity is transmitted to the deformation area 4 through the first transmission rod 3-1 and the second transmission rod 3-1, so that the deformation area 4 is synchronously changed along with the deformation of the supporting upright post 1.
And attaching a resistance strain gauge to the deformation area 4, measuring the strain of the deformation area 4 through the resistance strain gauge, and converting the measured force of the object into an electric signal for output. If the small displacement change δ caused by the force is set to be the portion of the support column 1 between the first fixing member 2-1 and the second fixing member 2-2, which has the length L, the corresponding strain α is δ/L. The deformation zone 4 changes synchronously with the deformation of the strut 1, and the strain β of the deformation zone 4 is δ/h. Therefore, the ratio K of the strain α to the strain β is (β/α)/(δ/L) is L/h, and thus, the original slight strain of the support column 1 is equivalently amplified by K times by the above structure, and the object supported by the support column 1 can be measured with high precision.
The column loading force sensor arrangement 5 shown in fig. 1 is applied to a large storage silo or large storage tank 6, resulting in the arrangement shown in fig. 2. After the method is adopted, the supporting structure of the original large storage bin or large storage tank 6 cannot be damaged, the strain of the large storage bin or large storage tank 6 can be equivalently amplified by K times and then measured, and the measurement precision is improved. The column loading force sensor structure provided by the invention can also be applied to the force measurement of large structural members such as bridges, towers, guys and the like, and is not described again here.
