Tower crane anti-leaning intelligent monitoring system

Abstract

The invention discloses a tower crane anti-leaning intelligent monitoring system. The intelligent monitoring system comprises a tower top detection device and a ground monitoring device, wherein the tower top detection device comprises a first sensor arranged on the XY plane, a second sensor arranged on the XZ plane, a first signal processing circuit, a second signal processing circuit, a digital-analog conversion circuit, a CPU module and a warning device, wherein the Y-axis is in the vertical direction of the ground; and the ground monitoring device comprises an input device, a CPU unit and an overlarge tilt angle warner. The invention has the following advantages that: two sensors are used, the three-axis acceleration measurement method is adopted to obtain the two-axis tilt angle and the measurement of the tower top tilt angle is more accurate. The tower top tilt angle is corrected by the CPU unit to directly determine the risk grade of a tower crane in a working state or a non-working state, thus increasing the efficiency of the building construction and reducing the risk of the tower crane collapse or breakage accident.

Description

Technical field [0001] The invention belongs to the technical field of tower cranes, and in particular relates to a tower crane anti-tilting intelligent monitoring system. Background technique [0002] In the construction of all high-rise buildings, tower cranes are currently the most widely used vertical transportation machinery. Tower cranes are high-tech equipment in construction crane equipment. The entire process from installation, use to disassembly is basically high-altitude operations. If the tilt angle of the tower top exceeds the specified value, accidents are prone to occur during the construction process. [0003] On July 14, 2008, on a construction site on Daqing Road, Baoji City, a tower crane about 50m high broke down. 6 workers were killed and 4 others were injured. On July 2, 2009, Chongqing A 34-meter-high tower crane on a construction site in Dazhulin High-tech Zone overturned; on May 3, 2010, a more than 30-meter-high tower crane under construction on a constru...

Problems solved by technology

Therefore, tower crane overturning accidents occur from time to time in Chongqing and even the whole country. These accidents have caused great damage to the people, lives and property, brought heavy psychological pressure to the construction workers, and had a bad social impact.

[0004] At present, the tilt angle is usually obtained by integrating the output of the gyroscope. Although this method is simple, as the integration period increases, the measurement error will gradually increase; in addition, the real-time performance and measurement accuracy of the gyroscope measurement are difficult to handle in engineering

Due to different construction stages and different application occasions, the safety range of the tower top inclination angle is different, and simply detecting the tower top inclination angle cannot meet the needs of actual construction
