Description

Hanging beam

technical field

The invention relates to the technical field of hoisting machinery, in particular to a hoisting beam for hoisting an industrial device module.

Background technique

With the construction of large-scale offshore equipment, there are more and more divisions of large-scale sections, and the construction mode tends to be modularized. The search for new tooling equipment is increasing, and the tooling equipment required for conventional construction is difficult to meet. The development needs of Sunsea Engineering, especially the conventional hanging beam tooling, are more difficult to meet the needs.

The main beam body of the conventional hanging beam is generally a beam in the form of round steel pipe, channel steel, and I-beam. The number of lifting rings is limited, and the upper and lower rings are symmetrically distributed. The main beam body in the form of round steel pipe, channel steel and I-beam has the disadvantages of large weight, small moment of inertia of the section, poor stability of the pressure rod, and small lifting tonnage; the upper and lower rings are symmetrically distributed, and the disadvantage is that single hook lifting will have huge bending moment Produced, the pressure on the hanging beam structure is large, and the beam body is damaged.

When used for hoisting, the fixed pulley is usually used to achieve the widening requirement of the lifting point, and a long rope needs to be connected to the lifting object through the pulley shaft. Since the long rope rotates on the shaft, the body of the conventional pulley will be worn, and the long rope will rotate and cannot be fixed, so the judgment of the center of gravity of the lifting object is extremely high, and there is a potential safety hazard of eccentric deflection of the lifting object, which can easily cause the sudden turning of the lifting object. ; Or due to the span of the hanging point, in order to ensure a reasonable hoisting angle between the hanging point and the long rope, the length of the long rope will be required to be longer. Therefore, there are strict requirements on the material, diameter and length of the long rope, such as the use of steel wire rope. In addition, the minimum bending radius of the wire rope directly affects the diameter of the pulley. In order to protect the pulley body from wear and reduce the constraints of the pulley diameter, the method of changing the rope material and replacing the rope with a small minimum bending radius, such as nylon rope, will cause the lifting capacity to be greatly reduced. Therefore, it is also necessary to invent an accessory that can match the main beam part of the hanging beam in order to meet the requirements of the width of the hanging point.
