Tower Crane Balance Weight Locking Device and Its Locking Method

Abstract

The invention relates to a tower crane balancing weight locking device. The tower crane balancing weight locking device comprises two first stranded wire seats, two second stranded wire seats, a first flexible stranded wire and a second flexible stranded wire. The two first stranded wire seats and the two second stranded wire seats are respectively arranged on a first main chord and a second main chord, and each first stranded wire seat is arranged between the tail end part of a balancing arm and the corresponding second stranded wire seat in the length direction of the balancing arm. Two ends of the first flexible stranded wire are respectively fixed on the first main chord and the second main chord and arranged on the two first stranded wire seats in a penetrating manner so as to bale a balancing weight. Two ends of the second flexible stranded wire are respectively fixed on the first main chord and the second main chord and arranged on the two second stranded wire seats in a penetrating manner so as to bale the balancing weight. According to the tower crane balancing weight locking device, the space below the tail part of the balancing arm can be saved, the space above the tail end part of the balancing arm is adequately used for storing the balancing weight, the twist resistance of the balancing weight can be improved, and overall mechanical parameters of a movable-arm tower crane can be improved. The invention also relates to a locking method of the tower crane balancing weight.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a locking device for a counterweight of a tower crane and a locking method thereof. Background technique [0002] At present, due to the small size and small footprint of the small boom tower crane, small boom tower cranes are generally used to transport building materials and install building components in construction sites with very strict construction space and schedule requirements (such as old city renovations). . In order to realize the balanced state of the luffing jib tower crane, a balance weight is usually installed at the tail of the main chord of the balance arm of the luffing jib tower crane. figure 1 It is a structural schematic diagram of an existing tower crane counterweight locking device. see figure 1 , in the existing boom tower cranes, a counterweight 11 of a certain weight is installed in the space below the main chord 10 of the balance arm, and a counte...

AI Technical Summary

Problems solved by technology

However, due to the limitation of the length of the balance arm of the small or ultra-small luffing jib tower crane, the installation space for installing the counterweight is very narrow, and the limited installation space brings difficulties to the structural design and locking method of the counterweight of the luffing jib tower crane. It is extremely difficult and becomes the bottleneck of the improvement of the overall mechanism parameters of the luffing jib tower crane
