Description
Technical field
The utility model relates to a kind of weighing device, particularly relates to a kind of weighing device that is applied to aerial work platform.
Background technology
Aerial work platform is widely used in the industries such as shipbuilding, municipal administration, building, harbour machinery, belongs to special equipment.The main parameter of measurement of aerial work platform is load-bearing capacity, security, reliability to its machinery itself enjoy people to pay close attention to, and the overload of the aerial work platform in the operation is to bring out the security incident one of the main reasons, and therefore accuracy, the validity of overload detection are the effective means that guarantees Product Safety.Existing test format is (Fig. 1) as shown in the figure: pressure transducer vertically is installed between work hurdle bracing frame and the rotary actuator fixed support, when the work hurdle is subject to load, because Action of Gravity Field, drive quadrilateral weighing support upper and lower displacement change, its pressure transducer that is installed in the weighing support is pushed, come senses change in pressure.Because the pressure transmission is through quadrangular mechanism, the manufacturing factor of mechanism own and friction force can exert an influence to the power transmission, therefore directly reaction pressure is big or small, thereby precision and the accuracy of load are measured in impact.
The utility model content
Technical problem to be solved in the utility model provides a kind of precision and high weighing device that is applied to aerial work platform of accuracy of measuring load.
In order to solve the problems of the technologies described above, the weighing device that is applied to aerial work platform that the utility model provides, comprise work hurdle bracing frame and rotary actuator fixed support, be connected to become the quadrilateral that can move up and down with web joint and clamping plate between described work hurdle bracing frame and the described rotary actuator fixed support, described work hurdle bracing frame is provided with the first axis hole installing plate, described rotary actuator fixed support is provided with the second axis hole installing plate, upper joint sleeve, Compress Spring and lower joint sleeve successively movable set on axle, end away from described upper joint sleeve of described axle is hinged on described the second axis hole installing plate, described upper joint sleeve is hinged on described the first axis hole installing plate, also comprise an alarm control unit, the travel switch of described alarm control unit is installed on the described work hurdle bracing frame and the contact of described travel switch aligns the top of described axle and leaves the displacement interval of weighing.
Be provided with the setting nut that described upper joint sleeve, Compress Spring and lower joint sleeve is carried size adjustment at described axle.
End away from described upper joint sleeve of described axle adopts lower stationary shaft to be hinged on described the second axis hole installing plate.
Described upper joint sleeve adopts upper stationary shaft to be hinged on described the first axis hole installing plate.
Adopt the weighing device that is applied to aerial work platform of technique scheme, when work hurdle bracing frame is subject to load, because Action of Gravity Field can be to sinking, the upper joint sleeve that drive work hurdle bracing frame connects moves down along axle, Compress Spring is compressed, the travel switch that wherein is fixed on the work hurdle bracing frame is followed together to bottom offset, when the larger variation of displacement meeting generation surpasses designed stroke when overload, travel switch contact and axle trigger, produce and in time to make caution after signal is delivered to controller, remind the operator, and limit some dangerous play, prevent that security incident from causing.
Compared with prior art, the utility model has the advantage of: 1. adopt its simple and stable structure of mechanical hook-up reliable; 2. contact is adopted its feedback of travel switch fine motion test format precisely, and is quick; 3. setting nut can be regulated carrying size, reaches desirable requirement.
In sum, the utility model is a kind of precision and high weighing device that is applied to aerial work platform of accuracy of measuring load.
