[0002] Crane anti-slant is a safety design to ensure the stability of the crane during operation and prevent it from tilting or overturning. The inclined system includes cables, structures connecting the crane and supporting structures, and is widely used.

[0003] The existing publication number CN215558465U discloses a tower crane containing an anti-slant pull detection device, comprising a tower body, a boom fixedly connected to the top of the tower body, a detection assembly fixedly connected to the lower right end of the boom, the detection assembly comprising a detection box, an upper support column fixedly connected to the middle of the top inside the detection box, a semi-guide ball fixedly connected to the bottom end of the upper support column, a plurality of first contact blocks uniformly fixedly connected to the upper end of the inclination detection plate in an annular direction, a connection plate fixedly connected to the inner wall of the detection box at the upper end of the outer wall of the semi-spherical cover, a circle of second contact blocks corresponding to the first contact blocks fixedly connected to the bottom end of the connection plate;

[0004] In the above document, the driver can be reminded to stop illegal operation by sounding an alarm and flashing a warning light to ensure the safety of tower crane lifting. When the wire rope tilts to a certain direction, the warning light in the corresponding direction flashes, so that the driver can quickly adjust the angle of the wire rope according to the prompt of the tilt direction. The detection prompt is detailed and obvious, which reduces the difficulty of operation for the staff; however, the bottom of the above detection device has a diameter much larger than that of the cable, and external dust can easily enter, affecting the detection accuracy of the detection device. At the same time, the installation structure of the device and the end of the crane frame is relatively simple, and it is not easy to disassemble and repair the device.
