Railway freight car overload and unbalanced load detection device

The utility model discloses a railway freight car overload and unbalanced load detection device which is widely applied to freight car overload and unbalanced load detection of railway freight car loading. Comprising a displacement sensor module and a clamp fixing module, the displacement sensor module comprises a sensor probe, a sensor shell, a displayer, a power switch, a Bluetooth transmitter and a metering unit, and the clamp fixing module is composed of a magnet, a rotary knob, a right-angle device, a bolt, a nut and the like. The displacement sensor module is matched with the clamp fixing module, data transmission to an external terminal is completed through the Bluetooth transmitter, the weight of loaded goods and the loading center-of-gravity position are determined, and the problems that the loading center-of-gravity position is determined through a traditional measuring scale lineation and visual inspection method, the loading process cannot be quantitatively controlled, and the loading accuracy is
