Abstract

The invention relates to a broken link self-anti-drop loop chain hoisting machine, comprising a driving wheel, an upper hook, a lower hook and a chain wheel, wherein the driving wheel is used for providing a driving force; the upper hook is arranged on a hoisting height position; the lower hook is used for hanging the lifted objects; the chain wheel is used for providing loop chain commutation; the upper hook is arranged on an upper mounting base; the lower hook is arranged on a lower mounting base; the driving wheel is arranged on the upper mounting base; at least one chain wheel and the chain engaged with the chain wheel and the driving wheel are arranged on the upper mounting base and the lower mounting base; the driving wheel and each chain wheel are equipped with a chain top press wheel; the outer side of the chain is engaged with the chain top press wheel; the inner side of the chain is engaged with the outer profile of the chain wheel; one end of the chain is fixed on the upper mounting base or the lower mounting base; the chain wheel and mounting element thereof are provided with two-way braking self-locking safe brake devices. The invention is simple in construction, high in reliability, short in braking distance, safe and reliable, and is applied to the engineering fields such as building, machinery, metallurgy, mine, vehicle, shipping and the like.

Description

technical field [0001] The invention relates to hoisting and hoisting equipment, and more specifically relates to a broken chain self-preventing ring chain hoist. Background technique [0002] Chain hoist, also known as hoist, is a light-duty hoisting equipment, which is widely used in the slow hoisting of objects in construction, machinery, metallurgy, mining, vehicles, ships and other engineering fields. During the use of the hoist, due to the harsh working environment, the chain is easy to break, causing the hoisting heavy objects to fall, causing equipment damage and casualties. [0003] Chain hoists are also commonly used in the field of attached lifting scaffolding. Attached lifting scaffold is the equipment used in the construction of high-rise buildings and super high-rise buildings. During use or operation, the lifting or lowering process is carried out slowly, and the chain hoist is often used as the lifting device. During the lifting or lowering of the scaffold,...
