The invention relates to a sensing device, and specifically relates to a
ground contact sensing device used for a loading
shovel. The
ground contact sensing device used for a loading
shovel comprisesa balance sensing device, a
signal generation device, and a guard
signal device. The balance sensing device is fixedly arranged on a loading
machine body. The
signal generation device and the balancesensing device are linked. The signal generation device and the guard signal device are connected through a wire. The balance sensing device comprises a
gravity center detection device, a
data acquisition unit, and a processor. The
gravity center detection device is electrically connected with the
data acquisition unit. The
data acquisition unit and the processor communicate in a
wireless manner.The balance sensing device of the
ground contact sensing device used for a loading
shovel is fixedly arranged on the loading
machine body. At the moment when the shovel contacts ground, pressure of front wheels is reduced, and the front wheels lift up, so that when the loading
machine body inclines, the balance sensing device acts on the signal generation device, to make the signal generation device gives out signals, so as to control a guard signal to prompt drivers in methods of sound, light, or vibration. The device has active effects of sensitive sensing, convenient use, and simple structure.
