Embodiment Construction

[0024] Such as Figure 1~5 As shown, a turning hanger includes a main beam 1 and a balance beam 2, the two ends of the main beam 1 are equipped with the balance beam 2, and the main beam 1 and the balance beam 2 are connected by a connecting shaft 3, The balance beam 2 rotates 360° with the axis of the connecting shaft 3 as the axis, and the two ends of the balance beam 2 are connected with the crane hook 8 through the rigging 4; when turning over, the main beam 1 is installed On the main tower 7, the middle part of the main beam 1 is connected with the main tower 7, and the main beam 1 and the main tower 7 rotate relative to the balance beam 2 at the same time to realize the turning of the main tower.

[0025] Such as Figure 4 As shown, the outside of the connecting end of the balance beam 2 and the connecting shaft 3 is provided with a cylinder support 6, and a hydraulic device 5 for dismounting the balance beam is provided between the cylinder support 6 and the connection...

Abstract

The invention discloses a turnover lifting tool which comprises a main beam and balance beams. The balance beams are mounted at the two ends of the main beam, the main beam and the balance beams are connected through connecting shafts, the balance beams rotate by 360 degrees with the axes of the connecting shafts as axes, and the two ends of each balance beam are connected with crane hooks through rigging. In the turnover process, the main beam is mounted on a main tower, the middle of the main beam is connected with the main tower, and the main beam and the main tower rotate relative to the balance beams at the same time to achieve turnover of the main tower. The turnover lifting tool is reasonable in structural design, and turnover and lifting are carried out at the same time. The connecting faces of the balance beams and the rigging are in arc design, so that the service life of the turnover lifting tool is prolonged. Due to the design of a hydraulic device, the balance beams can be fast detached, and production efficiency and safety degree are effectively improved through the turnover lifting tool.

Description

technical field [0001] The invention relates to the technical field of hoisting slings, in particular to an overturning sling. Background technique [0002] In the actual production of large-scale engineering installation operations, the suspended objects are oversized and long, and need to be transported to the site before being turned over and hoisted for installation. For example: the vertical installation of the main tower of the cable-stayed bridge, the inverted installation of the petrochemical reactor, the inverted installation of the nuclear power reactor, and the installation of the wind power tower in the wind field. Under the existing technical conditions, mostly rely on simple hoisting equipment to hook a certain position of the overturned article, and rely on the article and the ground contact position to overturn as the rotating shaft of overturning. There are many uncertain factors in the operation process of this reversal, and dangerous situations often occu...
