Intelligent obstacle avoidance tower crane capable of dynamically changing balance weight

Abstract

The invention discloses an intelligent obstacle avoidance tower crane capable of dynamically changing a balance weight. The intelligent obstacle avoidance tower crane comprises a vertically-arranged tower crane tower, a suspension arm perpendicular to the tower crane tower, a cargo hoisting mechanism arranged below a hoisting arm, a balance weight bin arranged below a balance arm, a rotating mechanism located at the intersection of the hoisting arm and the tower crane tower, and a command module located on the rotating mechanism. A server calculates real-time load torque of a hoisted object ofthe hoisting mechanism through stress sensors arranged on the balance arm and the hoisting arm, the horizontal movement distance of the balance weight bin is controlled through the real-time load torque, the server judges whether obstacles exist on a traveling path of the cargo hoisting mechanism or not, then obstacle avoidance is carried out, and thus the cargo hoisting mechanism is free of obstacle disturbance in the moving process. The intelligent obstacle avoidance tower crane is highly intelligent, the problem that quick and accurate obstacle avoidance cannot be realized in the prior artis solved, the position of the balance weight can be adjusted according to the weight of the hoisted object, automatic balance of the balance weight is achieved for the tower crane, and thus the construction tower crane operates more stably.

Description

technical field [0001] The invention relates to the field of tower cranes, in particular to an intelligent obstacle-avoiding tower crane that dynamically changes counterweights. Background technique [0002] With the development of science and technology, more and more new technologies and instruments are used in the construction industry. The construction pendant is one of the important tools in construction. The height of the construction pendant is generally relatively high, which leads to the stability of the pendant itself. The stability is not good, and the balance of the top is not good. The current pendant tower is simply equipped with counterweights. At present, the counterweights are fixed. When lifting heavy objects, the balance is not easy to grasp, because the construction crane The tower will drop different heavy objects, resulting in poor balance control and more dangerous during use. The existing tower crane control system mainly solves safety production pro...

Problems solved by technology

[0009] The purpose of the present invention is to overcome the above problems existing in the prior art, and provide an intelligent obstacle avoidance tower crane that dynamically changes the counterweight. , the handling efficiency is low, the obstacle avoidance problem cannot be fast and accurate, and the obstacle interference is avoided. The data is accurate, and the centralized digital management and monitoring can adjust the position of the counterweight according to the weight of the hoisted object, realizing the automatic configuration of the tower crane. Heavy balance, so that the construction crane tower is more stable during work, avoiding interference from human factors, and realizing the intelligent operation of the tower crane
