Center hole jack rigging for hoisting

Abstract

The invention discloses a center hole jack rigging for hoisting. The rigging comprises a snap ring, and further comprises a lockset support, a center hole jack, a steel strand, a steel strand clamp holder and a lifting lug plate, wherein the upper end of the lockset support is provided with a hoisting hole, the center hole jack is fixedly mounted on the lockset support, the steel strand penetrates through the center hole jack, the upper end of the steel strand clamp holder is connected with the lower end of the steel strand, and the lifting lug plate is used for connecting the steel strand clamp holder and the snap ring. According to the rigging, the adjusting length of the rigging is only related to the length of the steel strand, as long as the steel strand is long enough, the rigging has enough adjusting length, even if a difference between a shape of a steel structure assembly unit during hoisting and a shape of the steel structure assembly unit during in-place installation is large, as long as the length of the steel strand is enough, the rigging has enough adjusting length, the steel structure assembly unit can be converted from the shape of the steel structure assembly unit during hoisting to the shape of the steel structure assembly unit during in-place installation in a hoisting process, and other auxiliary cranes do not need to be used for auxiliary installation construction, so that the installation construction of the steel structure assembly unit is very convenient.

Description

Technical field [0001] The present invention relates to the field of lifting rinds, specifically a lifting of a heart-knitted jack. Background technique [0002] With the development of society, especially the continuous advancement of science and technology, people's lives have been greatly improved and improved; with people who have a happiness that people enjoy the increasing material life, for spiritual culture, living environment Wait a higher and higher requirements. [0003] The steel structure is increasingly common, and the assembled unit of steel structure should be quickly installed, and the steel structure assembled units should be achieved from the lifting time when it is lifted to the installation position. Shaped to the transition of the position of the position installation. Traditional lifting locks are generally a combination of steel wire rope or wire rope + inverted combination, which can be adjusted to be limited, and when the stitching of the steel structure...
