Dynamic balance building tower crane

Abstract

The invention relates to a dynamic balance building tower crane which is a lifting appliance in the field of building machinery, and in particular to a dynamic balance building tower crane with a balance weight dynamically moving with lifting weight. The dynamic balance building tower crane comprises a weight, a tower frame, a balance weight, a pivot point, a lifting motor and a cable rope, wherein the electric movable balance weight comprises a controller, a balance weight motor, a movable rail, a weight pulley wheel and a pressure sensor; the pressure sensor is arranged on a lifting point of the weight, and connected with the controller; and the controller is connected with the balance weight motor, the balance weight motor drives the weight pulley wheel to move on the movable rail. The dynamic balance building tower crane solves the problem of lifting arm imbalance of the tower crane in China and abroad, realizes the relative balance of the lifting arm by the movement of the balance weight, automatically moves the balance weight back and forth, reduces the safe accidents of building crane inclination, and decreases the life damage on building workers by the crane. The weight of the lifting arm can be accurately calculated by using the controller of the balance weight.

Description

Technical field: [0001] A dynamic balance building tower crane is a kind of lifting equipment in the field of construction machinery, and particularly relates to a building dynamic balance lifting tower crane whose counterweight moves dynamically with the lifting weight. Background technique: [0002] At present, the weight of building tower cranes at home and abroad is movable, and the materials to be lifted are lifted to the required position by moving forward and backward. Considering that the weight will make the boom unbalanced, set a fixed counterweight in the opposite direction of the boom, roughly estimated Then add appropriate counterweight, set a limit for the maximum lifting (weight) of each distance of the boom, adjust and set the limiter, and the operator determines the lifting weight according to the requirements of the limiter during operation. When the weight moves back and forth, the whole boom is in an unbalanced state. In order to lift more things, some w...

AI Technical Summary

Problems solved by technology

In order to lift more things, some workers on the construction site adjusted the limiter without permission, which artificially increased safety hazards.

Foreign countries have installed tower crane real-time monitors (commonly known as black boxes) in order to prevent the tower crane limiter from being adjusted privately, but they have not fundamentally solved the problem that the entire boom is in an unbalanced state when the weight moves back and forth. Safety accidents caused by imbalance occur frequently at home and abroad
