The utility model content
The purpose of this utility model is to provide a kind of load that is applicable to pitch pin formula fork truck and weighs and the load gravity center measurement mechanism, and its reliability is high, and accuracy rate is high, and can also measure the load gravity center position.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of load that is applicable to pitch pin formula fork truck is weighed and the load gravity center measurement mechanism, comprise two car pin, be located at respectively two car pin two groups of pressure sensors, be electrically connected on the control processor of two groups of described pressure sensors, every group of pressure sensor comprises mutual electrical connection and is located at respectively corresponding car pin near the pressure sensor of wheel carrier place and heel section.
Measure the suffered stress of car pin diverse location by being arranged on two pressure sensors on the car pin, then by the calculating of control processor, draw load weight value comparatively accurately; And the zone that the center-of-gravity position of the load in fork pin formula fork truck can the overpressure sensor surround, therefore, can also measure by pressure sensor the center-of-gravity position of load, method is as follows: a normal loading is positioned on the car pin, this moment, each pressure sensor was measured a stress value, record by control processor, the position of establishing normal loading this moment is normal place, and record normal loading this moment is " 0 " dotted state at the state of normal place lower pressure sensor; During actual load-carrying, the stress value that each pressure sensor records is by the control processor record, and these stress and " 0 " dotted state are compared calculating, thereby draws actual load quality and actual load center of gravity.
As of the present utility model preferred, described pressure sensor is metal strain chip sensor.
That metal strain chip sensor has is simple in structure, size is little, lightweight, cheap and at high low temperature, at a high speed, the characteristics that work under the mal-conditions such as high pressure, severe jolt, high-intensity magnetic field and chemical corrosion, be fit to very much use on fork pin formula fork truck.
As of the present utility model preferred, described car pin has mounting groove; Described pressure sensor is embedded in described mounting groove.
As of the present utility model preferred, the upper surface of described pressure sensor maintains an equal level in the upper surface of corresponding described car pin.
As of the present utility model preferred, described car pin has be used to the mounting groove of installing described pressure sensor; Also be embedded with the protective cover plate that covers described pressure sensor in described mounting groove.
As of the present utility model preferred, the upper surface of described protective cover plate maintains an equal level in the upper surface of corresponding described car pin.
As of the present utility model preferred, connect by cable between every group of described pressure sensor, and described cable burial is in corresponding described mounting groove.
In sum, the utlity model has following beneficial effect: the utility model structure, easy to implement; And survey precision is high, not only can measure the quality of load, can also measure the center-of-gravity position of load; And sensor is imbedded the car pin, can not affect the height of car pin.
