Description

Technical Field

[0001] The utility model relates to hoisting in construction engineering and mechanical engineering, and particularly relates to a safety device for preventing large-angle limit in quick-disassembly hoisting. Background Technique

[0002] In hoisting operations, the included angle of the steel wire rope is an important safety consideration. According to relevant safety regulations, the included angle of steel wire rope hoisting generally should not exceed 120 degrees to prevent the steel wire rope from breaking due to excessive stretching. In addition, the included angle between the sling and the horizontal plane should not be less than 45 degrees. If the included angle is less than 45 degrees, auxiliary supports must be added between the slings to ensure safety. When high-altitude hoisting operations are carried out in various engineering constructions, in order to prevent the large-angle installation of the steel wire rope, the hoisting point of the goods is often adjusted smaller. However, this scheme cannot hoist to the maximum hoisting point of the goods, and is too limited for heavy goods with a large span. Hoisting heavy goods is affected by the hoisting force due to the limited hoisting distance, and a hoisting machine that meets the parameters needs to be readjusted. By restricting the displacement of the steel wire rope through a limit device, the maximum hoisting point can be calculated, which is beneficial to the hoisting work of heavy large-span materials.
