Multifunctional hoisting balance beam

Technical Field

The invention belongs to the technical field of hoisting and hanging, and particularly relates to a hoisting balance beam for keeping balance of hoisted equipment.

Background

At present, the design of domestic oil refining chemical complete equipment is heavier and heavier, the capacity of a large crane tends to be the limit, and the requirement on a hoisting rigging is higher and higher. The balance beam is one of common hoisting parts, is mainly used for connecting hoisted equipment through a steel wire rope rigging, is used for keeping balance of the hoisted equipment, avoids a sling from damaging the equipment, and is widely applied to hoisting engineering. When a plurality of machines lift and hang, the load of each hanging point can be reasonably distributed or balanced by adopting the balance beam.

At present, the traditional balance beam and the lifting hook are often connected by a steel wire rope, the distance between the balance beam and the lifting hook cannot be avoided, and the lifting height is increased, so that the crane is required to be provided with a longer arm rod. According to the performance of the crane, under the condition that the hoisting radius is not changed, the longer boom rod means that the rated load of the crane is lower, and the hoisting capacity of the crane is reduced, so that the potential of the crane on the performance cannot be fully exerted. In some cases, even a crane of a larger ton size is required to be used instead to complete the hoisting, which greatly increases the construction difficulty and cost.

Further, the diameters of the edge pin hole are all the same.

Further, the middle pin shaft hole and the edge pin shaft holes are located at the same horizontal height.

Furthermore, a shaft sleeve is sleeved outside the side pin shaft.

Furthermore, an inner side reinforcing plate and an outer side reinforcing plate are arranged on the main beam plate around the middle pin shaft hole; the inner side reinforcing plate is welded on the inner side face of the main beam plate, and the outer side reinforcing plate is welded on the outer side face of the main beam plate.

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:

as shown in fig. 1 to 4, the present embodiment provides a multifunctional hoisting balance beam, which includes a main beam plate 1, a connector 2, a middle pin shaft 3, an edge pin shaft 4, a shaft sleeve 5, a middle inner side reinforcing plate 6, a middle outer side reinforcing plate 7, an edge reinforcing plate 8, and a lifting lug 9.

The middle pin shaft hole and all the side pin shaft holes are located at the same horizontal height, so that the hoisting height can be shortened during hoisting, and the crane can use shorter arm rod length to increase the hoisting capacity.

The two main beam plates 1 are arranged in parallel, and two ends of the two main beam plates are aligned respectively; the two main beam plates 1 are connected into a whole through the connecting body 2.

The connector 2 is typically located between the center pin hole and the edge pin hole of the main beam panel 1 to prevent interference with the installation of the center pin 3 and the edge pin 4.
