Description

Technical Field

[0001] This utility model relates to the field of construction hoisting and lifting, specifically a sling structure for hoisting 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 sling structure for hoisting large pipe culverts. Summary of the Invention

[0004] The purpose of this utility model is to provide a sling structure for hoisting large culverts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sling structure for hoisting large culverts is characterized in that the sling includes a U-shaped ring and a steel wire rope. The U-shaped ring is provided with a sling pin and is used to connect the steel wire rope. The steel wire rope is divided into three sections, which are separated by two steel wire rope clamps. The upper and lower sections are double-layered steel wire ropes, and the middle section is a single-layered steel wire rope. The lower part of the steel wire rope is connected to a fixing pin.

[0007] Furthermore, the steel wire rope is made of galvanized material.

[0008] Furthermore, the sling is shaped like an "8".

[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.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The threaded fixing pin of this utility model is threadedly connected to the threaded lifting hole on the culvert, so that the fixing pin is firmly fixed to the culvert. At the same time, the auxiliary hook of the crane is used to attach a hook ruler to the front end of the culvert and fix it to the culvert, making the lifting process more stable and the lifting efficiency higher.
