Abstract
The present invention relates to a kind of overload protection arrangement of LOAD CELLS; comprise stationary installation and the sensor that is connected on the stationary installation; also comprise spring, stop and prestressed adjusting bolt; can produce prestressed spring and be contained on stationary installation or the sensor by prestressed adjusting bolt, stop is contained on sensor or the stationary installation.Because the present invention has adopted the overload protection arrangement of spring structure, have simple in structurely, easy for installation, can satisfy the performance index of LOAD CELLS, advantage such as can play a protective role when overload again.This protective device is specially adapted in the various forms of LOAD CELLS.
Description
The present invention relates to a kind of overload protection arrangement of LOAD CELLS, it belongs to the overload protection arrangement of sensor.
LOAD CELLS is the device that weight or power is converted to electric signal, it be widely used in various weigh and dynamometric system in.Present LOAD CELLS all has only measurement range, does not have overload protection arrangement, in case weight surpasses its measurement range, will cause the damage of LOAD CELLS, brings immeasurable loss to commercial production.
The purpose of this invention is to provide a kind of can guarantee to weigh accurately can when overload, play a protective role again and the overload protection arrangement of LOAD CELLS simple in structure, easy for installation.
The object of the present invention is achieved like this: overload protection arrangement comprises stationary installation and the sensor that is connected on the stationary installation; it also comprises spring, stop and prestressed adjusting bolt; can produce prestressed spring and be contained on stationary installation or the sensor by prestressed adjusting bolt, stop is contained on sensor or the stationary installation.
Described spring can be a volute spring, can also be butterfly spring, laminated spring.
Described stationary installation can be a bearing, also can be the support of framed structure.
Principle of work of the present invention is: make the prestressed of spring corresponding with the measurement range of LOAD CELLS by regulating prestressed adjusting bolt.When sensor is stressed when belonging to normal range, spring is indeformable, all by LOAD CELLS, thereby is not influenced the performance of LOAD CELLS by dynamometry.When the stressed overload of sensor; whole displacement takes place in camber of spring, LOAD CELLS, and stress point contacts with stop; the power that exceeds the LOAD CELLS measurement range directly is passed on the stationary installation by stop rather than by LOAD CELLS, plays the effect of protection sensor.
Because the present invention has adopted the overload protection arrangement of spring structure, compares with background technology, have simple in structurely, easy for installation, can satisfy the performance index of LOAD CELLS, advantage such as can play a protective role when overload again.This protective device is specially adapted in the various forms of LOAD CELLS.
Fig. 1 is the structural representation of the overload protection arrangement of LOAD CELLS;
Fig. 2 is the structural representation of the overload protection arrangement of pressure type LOAD CELLS;
Fig. 3 is the structural representation of the overload protection arrangement of cantilevered LOAD CELLS.
Below in conjunction with accompanying drawing the present invention is described in further detail.
As shown in Figure 1; the overload protection arrangement of LOAD CELLS comprises support (3) and is connected sensor (5) on the support (3); can produce prestressed volute spring (1) and be contained on the support (3) by prestressed adjusting bolt (4), stop (2) is contained in the lower end of sensor (5).When the stressed overload of sensor (5), spring (1) distortion, stop (2) moves down and touches support (3), and the power of transshipping is delivered on the support (3), plays the effect of protection sensor (5).
As shown in Figure 2; the overload protection arrangement of pressure type LOAD CELLS comprises support (3), prestressed adjusting bolt (4), sensor (5) and the support plate (6) of volute spring (1), stop (2), framed structure; spring (1) is regulated bolt (4) through prestressed and is contained between support (3) and the support plate (6); stop (2) is installed on the support (3), and sensor (5) is contained on the support plate (6).
As shown in Figure 3; the overload protection arrangement of cantilevered LOAD CELLS comprises volute spring (1), stop (2), bearing (3), prestressed adjusting bolt (4), sensor (5) and dog screw (7); spring (1) is regulated bolt (4) through prestressed and is contained on the sensor (5); sensor (5) is installed in above the support (3); and by dog screw (7) location, stop (2) is fixed on one side of support (3).
Spring in the above-mentioned overload protection arrangement can also be butterfly spring, laminated spring.
Claims (3)
1, a kind of overload protection arrangement of LOAD CELLS, it comprises stationary installation and the sensor that is connected on the stationary installation, it is characterized in that: it also comprises spring, stop and prestressed adjusting bolt; Can produce prestressed spring and be contained on stationary installation or the sensor by prestressed adjusting bolt, stop is contained on sensor or the stationary installation.
2, overload protection arrangement according to claim 1 is characterized in that: described spring can be a volute spring, can also be butterfly spring, laminated spring.
3, overload protection arrangement according to claim 1 is characterized in that: described stationary installation can be a bearing, also can be the support of framed structure.
