A safe hoisting device with anti-freezing function for building construction

Abstract

The invention relates to a safety lifting device used for building construction and with the anti-icing function. The device comprises a tower body, a balance arm, a lifting arm, a driving cabin and awinding device and further comprises a heating mechanism and an alarm mechanism; the heating mechanism comprises a heating chamber, a heating box, a fixed block, two communication pipes and four airspraying assemblies; each air spraying assembly comprises a supporting shaft, a nozzle, a hose and a driving unit; the alarm mechanism comprises an alarm box, a lifting hook, a connecting rod and an alarm assembly, and the alarm assembly comprises a connecting plate, a pressing plate, two first springs and two pressure sensors. According to the safety lifting device used for building constructionand with the anti-icing function, through the heating mechanism, the steel wire rope can be heated, the steel wire rope can be prevented from being iced under the frigid weather, therefore, winding effect is not affected, through the alarm mechanism, an alarm can be given out when the lifted cargo is too heavy, the equipment turnover caused by the too heavy cargo can be avoided, and the equipmentsafety is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a safety hoisting device with anti-freezing function for building construction. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane". , concrete, steel pipe and other construction raw materials. Tower crane is an indispensable equipment on the construction site. [0003] When the existing tower cranes work in cold weather, the steel wire rope is easily frozen, causing the steel wire rope to be unable to be wound, which affects the normal operation of the tower crane. Not only that, but the existing tower crane lifts the goods through the hook. If the goods are too heavy, it will cause The jib tilts, causing the tower crane to overturn in serious cases, posing a threat to the personal safety of the operator and reducing the safety of the equipment. Contents of the invention [0004] The te...
