A curved balance beam

Abstract

The invention discloses an arc balancing beam, which is characterized in that a beam body of the arc balancing beam is arc-shaped along the horizontal direction, a plurality of lifting points of the arc balancing beam are distributed into an arc shape consistent with the shape of a lifted arc barrel consisting of a plurality of devices, the number of the lifting points can be the same as that of the devices, and the positions of the lifting points are consistent with those of the devices. The balancing beam disclosed by the invention can conveniently lift an arc barrel consisting of a plurality of plate-type assembling structures which are distributed in an arc shape, and the lifting operation is high in efficiency, and is safe and reliable.

Description

Technical field [0001] The invention relates to hoisting construction equipment, in particular to an arc-shaped balance beam. Background technique [0002] Balance beam is an important part of hoisting equipment and is widely used in lifting engineering. The balance beam, also known as the iron pole, can be used to maintain the balance of the equipment being hoisted to avoid damage to the equipment by the sling; shorten the height of the sling, reduce the lifting height of the movable pulley; reduce the horizontal pressure on the equipment when lifting, and avoid damage to the equipment. However, the general balance beam cannot efficiently and safely and reliably solve the lifting problem of large arc-shaped plate assembled arc-shaped cylindrical parts. [0003] In addition, the upper end of the general balance beam is connected to the hoist pulley through hooks, wire ropes, and shackles. It takes up a large working space from the hook to the balance beam. Moreover, at the lower e...

However, the general balance beam cannot efficiently, safely and reliably solve the hoisting problem of large arc-shaped plate assembled arc-shaped cylinder parts

[0003] In addition, the upper end of the general balance beam is connected to the pulley of the crane through a hook, a wire rope, and a shackle. It takes a large working space from the hook to the balance beam. Moreover, at the lower end of the balance beam, a steel wire rope is used to hang on the balance beam through a shackle. The ear plate at the bottom is used for hoisting, and the connection distance is long

This leads to the fact that the existing balance beam cannot meet the hoisting operations of specific construction sites (such as those near the airport) that have restrictions on the working height of construction equipment.
