Shaft type lifting system for protecting steel wire rope

Abstract

The invention discloses a shaft type lifting system for protecting a steel wire rope, and belongs to the technical field of lifting equipment. The shaft type lifting system for protecting the steel wire rope comprises a shaft type lifting point and the steel wire rope, wherein an external contour type protective cover in sliding fit with the shaft type lifting point is arranged outside the shaft type lifting point, and covers the external of the shaft type lifting point; the steel wire rope is lifted outside the external contour type protective cover; and baffle plates respectively in stop fit with the external contour type protective cover are fixed at the two ends of the shaft type lifting point. The shaft type lifting point generates no direct contact with the lifting steel wire rope; in the lifting and overturning process, the lifting steel wire rope is only contacted with the external contour type protective cover; and the lifting steel wire rope and the external contour type protective cover are kept relatively stationary without sliding and rubbing, so that the damage caused by the sliding and the rubbing of the steel wire rope is reduced, and the service life of the steel wire rope is prolonged. Therefore, the shaft type lifting system can guarantee difficult damage of the steel wire rope in the lifting process.

Description

technical field [0001] The invention relates to a hoisting system capable of protecting steel wire ropes, in particular to a shaft-type hoisting system for protecting steel wire ropes, which belongs to the technical field of hoisting equipment. Background technique [0002] At present, in the traditional hoisting technology of chemical equipment, especially when hoisting tower equipment, the main lifting lug is mostly in the form of a tubular lifting lug, and the connection part of the shackle in the hoisting rigging is also mostly in the form of a pin shaft. During the hoisting process, the wire rope directly touches this type of shaft-type lifting point, and the wire rope will slide relative to the pin shaft during the hoisting and turning process, and the friction between the wire rope and the pin shaft will also cause great damage to the wire rope, making the wire rope easily damaged. Resulting in a reduction in the service life of the wire rope. Contents of the invent...
