Tower crane lifting hook anti-swing control system and method

Abstract

The invention discloses a tower crane lifting hook anti-swing control system and a method. The system comprises a lifting hook mounted on a lifting arm frame, a control device, and a rotation control device, a motor driving control device connected with a rotation motor and a detecting device, which are respectively connected with the control device. When the rotation control device sends rotation operation information to the control device, the control device sends a corresponding control instruction to the motor driving control device according to the operation information, the motor driving control device controls the rotation motor to operate, the rotation motor drives the lifting arm frame to rotate, and the lifting arm frame drives the lifting hook to rotate; the detecting device detects the acceleration of a lifting hook in real time and sends to the control device; and when a deviation delta a is generated between the acceleration at of the lifting hook received by the control system and a given acceleration a, the control system adjust the operation speed of the rotation motor in real time according to delta a until the real-time detected acceleration at is consistent with the given acceleration a, so that the stable control of the operation speed of the lifting hook is realized, and the anti-swing effect is achieved.

Description

technical field [0001] The invention relates to a hook anti-swing control system and method, especially suitable for tower cranes. Background technique [0002] At present, during the transfer construction process of the tower crane, due to the existence of inertial force, the operation of the boom and the hook will be out of sync, that is, the hook will swing. The swing of the hook will increase the difficulty of operation, inaccurate positioning, reduce the transfer efficiency, and easily hurt people. The lateral force caused by the swing will seriously damage the mechanical structure and even increase the risk of tipping. No good solution is proposed for this problem in the prior art, and it can only be controlled by the driver's operating experience. [0003] In the prior art, there is no good solution to the problem of tower crane hook swaying, and it can only be controlled by the driver's operating experience. This has the following disadvantages: 1. For the tower cr...

AI Technical Summary

Problems solved by technology

This has the following disadvantages: 1. For the tower crane hook swing control, it can only be controlled by the driver's operating experience, and the anti-sway effect can only be controlled by the driver's operating experience. Different drivers have large differences in operating effects, and the operation is difficult. , can not solve the swing problem well; 2. Low work efficiency; 3. Inaccurate positioning; 4. Easy to bruise people; 5. Serious damage to the mechanical structure
