Abstract
The utility model relates to a dynamic pulley shaft type sensor, which is mainly composed of an eccentric shaft, an elastic body and a resistance strain piece. Because of the action of the eccentric shaft, the force accepted by a pulley is always transferred to the elastic body along the vertical direction through the eccentric shaft; the resistance strain piece is made to generate deformation and voltage change signals. An electronic hanging balance made of the dynamic pulley shaft type sensor can be used for various cranes of warehouses, docks and workshops and can realize weighing goods in the hoisting, loading and unloading process.
Description
The utility model relates to a kind of dynamic pulley shaft type sensor.The more sensor of application is gone up by society at present sensors such as tensile force type, bridge-type, pillar, shearing beam type, condenser type.For the electronic crane scale sensor of on lifting machine, windlass, using, use be the tensile force type sensor, the installation site of electronic crane scale is on the suspension hook or under the suspension hook; The lifting of the power lead of steelyard along with hook lifting; Especially power lead is adjacent with hoisting wirerope again nearer in lifting process, causes dangerous easily.
In recent years, the wireless telecontrol electronic steelyard has appearred both at home and abroad.Sensor also adopts tensile force type.The power supply of wireless telecontrol electronic steelyard adopts ickel-cadmium cell.This electronic scales is compared with wired electronic crane scale, because the non-transformer line has solved the adjacent nearer unsafe factor that causes with wire rope of power lead of wired electronic crane scale.But the ickel-cadmium cell of the electronic crane scale of wireless remote control need often charge; Especially when voltage reduces, also occur numeral easily and show disorder and weigh the misalignment problem that constant charging is also made troubles to operation.
Task of the present utility model is to provide a kind of pulley shaft type electronic scales sensor that is applied to, with the electronic scales that this sensor is manufactured, is installed on the arm frame head of lifting machine, windlass, and be that electronic scale sensor is used as the lifting machine fixed pulley axis again.Because its power lead is fixed on the arm frame, the power lead that has solved the conditional electronic steelyard with the suspension hook activity bring dangerous.This sensor is when the lifting of lifting machine arm simultaneously, because suspension hook and hang the effect of thing weight can be regulated horizontality automatically, is a kind of electronic scales with dynamic pulley shaft type sensor.
Task of the present utility model is realized by following scheme:
Accompanying drawing is the utility model structural drawing.(1) is excentric shaft in the accompanying drawings; (2) be sensor elastomer; (3) be resistance strain gage.
Accompanying drawings structural principle of the present utility model.
(3) resistance strain gage is pasted on the elastomer (2) among the figure, and the elastomer that posts foil gauge press-fits on eccentric shaft (1); Eccentric shaft is the steel body of this sensor, also is the pulley spindle of lifting machine fixed pulley. After eccentric shaft was loaded onto fixed pulley, by the effect of lifting machine suspension hook and movable pulley steel wire rope, the weight of lifting machine lifting was delivered to power on the elastomer (2) by fixed pulley axis; The distortion of the resistance strain gage (3) that the elastomer distortion causes, because the effect of probe power voltage, the voltage change that the distortion of resistance strain gage (3) brings is by showing lifting machine lifting loading after the Computer Processing. Elastomer (2) press-fits on eccentric shaft (1) again, because wobbler action, after fixed pulley is stressed, eccentric shaft (1) center of gravity on the lower side, elastomer (2) center of gravity on the upper side, the lifting machine arm has realized that dynamic pulley axle type sensor remains vertically stressed, makes sensor in the course of the work reliable and stable when rising or descend.
Claims (3)
1, a kind of dynamic pulley shaft type sensor is made up of excentric shaft, elastic body, resistance strain gage, it is characterized in that:
Dynamically the elastic body that foil gauge is housed of pulley shaft type sensor and excentric shaft closely press-fit and are integral.
2, dynamic pulley shaft type sensor according to claim 1, when it is characterized in that said excentric shaft and elastic body are assembled together, the axial line of excentric shaft and center of gravity are lower than elastomeric axial line and center of gravity all the time.
3, dynamic pulley shaft type sensor according to claim 1 is characterized in that said excentric shaft and elastic body are assembled together; Also available a kind of elastomeric material is processed into integral type.
