Problems solved by technology
However, due to the structural elastic deformation factors of the tower crane, the inertia factors of the hoisting weight, and the deflection hoisting factors, etc., there must be an unstable hoisting problem in which the hook swings and twists with the hoisting weight during the hoisting process. The load accelerates the fatigue of the tower crane structure; on the other hand, it increases the difficulty of hoisting and positioning, and the efficiency of precise positioning is greatly reduced

The invention discloses a tower crane lifting hook posture detection and anti-swing device. The device comprises a shell, a six-axis sensor, an inclination angle sensor, a lora wireless module, a single-chip microcomputer, a power supply and a starting switch, wherein the shell is fixedly arranged on a side plate of a lifting hook, the six-axis sensor and the inclination angle sensor are arrangedin the shell, and the single-chip microcomputer and the power source are arranged in the shell; the starting switch is arranged on the shell; and the six-axis sensor, the inclination angle sensor, thepower supply and the starting switch are electrically connected with the single-chip microcomputer. The device has the advantages that the state of the lifting hook can be monitored in real time, a foundation is provided for the later-period research and development tower crane lifting hook anti-swing technology; whether lifting objects are lifted or not can be determined according to the state of the lifting hook, and an operator of a tower crane can adjust the moving speed and the lifting speed of the lifting objects according to the state of the lifting hook; and the device is simple in overall design and capable of preventing dust, water and collision.
Description
technical field [0001] The invention belongs to the technical field of tower crane equipment, and in particular relates to a tower crane hook posture detection and anti-sway device. Background technique [0002] At present, the tower crane on the construction site is controlled by the main engine of the tower crane, mainly to control the rotation of the tower crane, the movement of the luffing trolley and the lifting of the hook, which meets the basic requirements of the tower crane. However, due to the structural elastic deformation factors of the tower crane, the inertia factors of the hoisting weight, and the deflection hoisting factors, etc., there must be an unstable hoisting problem in which the hook swings and twists with the hoisting weight during the hoisting process. The load accelerates the structural fatigue of the tower crane; on the other hand, it increases the difficulty of hoisting and positioning, and the efficiency of precise positioning is greatly reduced....
