Description

Technical Field

[0001] The utility model relates to the technical field of tilt detection devices, in particular to a crane body tilt detection device. Background Art

[0002] Before the crane starts working, the left and right legs must be supported. When the road surface is uneven, or the left and right legs are of different lengths due to manufacturing errors, the body of the crane will tilt. Working in a tilted state will greatly reduce the lifting capacity of the crane and it is also very unsafe. Whether the body of the crane is level after the legs are supported is mostly judged by the operator's experience. A few cranes are equipped with a spirit level, but it can only roughly know whether the vehicle is level. The working conditions of the crane are changeable and complex, and there are often safety hazards.

The utility model can automatically detect the tilt angle of the crane body through the coordinated setting between the protractor, the driving device and the tilt sensor, and can also avoid the influence of the environment on the detection result.

[0004] The above-mentioned fuselage inclination detection device can automatically detect the inclination angle of the crane fuselage through the coordination between the protractor, the base plate, the driving device and the inclination sensor. However, the above-mentioned fuselage inclination detection device only uses the sensor to obtain the inclination angle, cannot intuitively display the inclination angle, and has no structure that can fit the side of the fuselage. The measurement accuracy is low and the effect is not good during use, which needs to be improved. Utility Model Content
