AI Technical Summary
In the existing technology, during the hoisting of large pipe culverts, the components have insufficient resistance to bending and flexural stress, the hoisting process is unstable, which can easily cause damage to the components, make alignment difficult, result in poor safety performance, and affect the construction progress.
A balance beam is designed to facilitate the hoisting of large culverts. It adopts a trapezoidal structure and is equipped with hoisting holes, reinforcing ribs, and a balance gauge. It is connected to the crane hook via slings and uses a hook gauge and fixing bolts to fix the culvert, thereby enhancing the stability and smoothness of hoisting.
This achieved stability and smoothness in the hoisting of large culverts, reduced the risk of component damage, and improved the safety and construction efficiency of the hoisting process.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction hoisting and lifting, specifically a balance beam that facilitates the hoisting of large culverts. Background Technology
[0002] Currently, the methods used for hoisting large culverts include: oblique hoisting and straight hoisting. In the oblique hoisting method, the culvert is tied in a horizontal position and can be lifted directly from inside without turning it over. After lifting, the slings are at the center of the culvert, allowing for a smaller lifting height, but alignment is inconvenient, and the center of the culvert must have sufficient bending resistance. In the straight hoisting method, the culvert must be turned over before hoisting. After lifting, the culvert is in an upright position, and the crane hook must extend beyond the top of the culvert. The slings are on both sides of the culvert, requiring a spreader bar. The required lifting height is greater than in the oblique hoisting method. The culvert has greater rigidity and enhanced bending resistance after being turned over. However, the culvert is perpendicular to the trench during hoisting, making alignment more difficult. Conventional culvert hoisting places high demands on the bending and flexural strength of the components. Improper use of hoisting points during the hoisting process can easily damage the components, make it difficult to align the culvert components, and result in poor safety performance during hoisting. The culvert may roll due to external forces, which can lead to waste of labor and materials and affect the construction progress.
[0003] To facilitate the hoisting of large pipe culverts, we designed a balance beam that makes it easier to hoist large pipe culverts. Summary of the Invention
[0004] The purpose of this invention is to provide a balance beam that facilitates the hoisting of large culverts, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A balance beam for facilitating the hoisting of large culverts is characterized in that the balance beam has a trapezoidal structure with left and right symmetry, a hoisting hole in the middle, symmetrical reinforcing ribs A and B on both sides, a balance ruler at the bottom, and a secondary ruler symmetrically arranged at the bottom of the balance ruler with multiple hanging holes for connecting slings.
[0007] Furthermore, the balance beam is connected to the crane hook through the lifting hole, and the sling holes at both ends of the balance beam are connected to the slings. The two slings are connected to both ends of the culvert respectively. The upper axial end of the culvert is connected to the third sling through the hook gauge, and the third sling is connected to the crane auxiliary hook.
[0008] Furthermore, the balance beam is made of steel.
[0009] During hoisting, the hoisting holes of the balance beam are attached to the crane hook. Both ends of the balance beam are connected to the sling pins of the slings through the attachment holes. The threaded end of the sling's fixing pin is then inserted into the hoisting pin hole of the culvert and threadedly connected to the threaded structure, making the hoisting more stable. The sling is attached to the crane's auxiliary hook through a third sling. The culvert is placed between the bottom of the sling and the auxiliary components, and the distance is adjusted and fixed with fixing bolts. The fixing bolts are tightened to secure the culvert to the sling, increasing the lifting capacity and making the hoisting more stable.

[0011] The lifting hole of the balance beam of this utility model is hung on the crane hook. The two ends of the balance beam are connected to the lifting pins of the sling through the hanging hole. Then, the threaded end of the fixing pin of the sling is inserted into the lifting pin hole of the culvert and threadedly connected to the threaded structure, so that the lifting is more stable.
