Problems solved by technology
[0002] During the use of tower cranes, due to the existence of structural elastic deformation factors, hoisting weight inertia factors, deflection lifting factors, etc. of the tower crane, there must be unsteady hoisting problems such as swinging and twisting of the hook with the hoisting weight during the hoisting process. On the one hand, it increases the load of the tower crane mechanism and structure, and accelerates the fatigue of the tower crane structure; on the other hand, it increases the difficulty of hoisting and positioning, and the efficiency of accurate positioning is greatly reduced

Embodiment Construction
[0016] The present invention is described in detail below in conjunction with accompanying drawing:
[0017] Such as figure 1 As shown, a tower crane hook anti-swing technology, including power supply equipment, lora wireless receiving module, display screen, start button, ARM single-chip microcomputer and sound and light alarm; it should also include external equipment, such as tower crane monitoring host, Tower crane PLC control board and hook detection equipment, tower crane monitoring host is the real-time safety protection monitoring of tower crane working conditions; tower crane PLC control board is used to control the hoisting mechanism and luffing mechanism of tower crane and rotary mechanism. The ARM single-chip microcomputer is electrically connected with the power supply equipment through the AD interface. The crane monitoring host and the tower crane PLC control board are always connected to the 485 interface of the tower crane monitoring host and the tower crane...

The invention discloses a tower-type crane hook anti-sway technology. The tower-type crane hook anti-sway technology comprises a power supply device, a lora wireless receiving module, a display screen, a start button and an ARM single chip microcomputer, and the power supply device, the lora wireless receiving module, the display screen and the start button are all electrically connected with theARM single chip microcomputer; and the ARM single chip microcomputer comprises a configuration module, an operation module, a management module, an output module, a monitoring receiving module and a buffer pool module. The tower-type crane hook anti-sway technology has the advantages that real-time dynamic attitude data of a hook can be monitored in real time, and the compensated acceleration of the movement of a trolley and the hook can be self-compensated and calculated according to the data; parameters can be compensated in the tower-type crane rotation, lifting and amplitude movement process, and the parameters can control a PLC system through a protocol converter to reduce the swing of the hook, and the improvement of the safety of a tower-type crane in the using process is facilitated.
Description
technical field [0001] The invention belongs to the technical field of tower crane equipment, and in particular relates to an anti-swing technology for a hook of a tower crane. Background technique [0002] During the use of tower cranes, due to the existence of structural elastic deformation factors, hoisting weight inertia factors, deflection lifting factors, etc. of the tower crane, there must be unsteady hoisting problems such as swinging and twisting of the hook with the hoisting weight during the hoisting process. On the one hand, it increases the load of the tower crane mechanism and structure, and accelerates the structural fatigue of the tower crane; on the other hand, it increases the difficulty of hoisting and positioning, and the efficiency of accurate positioning is greatly reduced. Therefore, there is an urgent need for a control system that can automatically adjust the lifting, luffing, and slewing movements of the tower crane in real time according to the pos...
