Heavy lifting device

Abstract

The invention relates to a heavy lifting device in the field of material conveying. A support is arranged on a base; multiple sections of the support are provided; cross connecting rods are arranged between all the sections of the support; an upper support base is arranged at the uppermost end of the support; a base is matched and provided with a lower conveyor; the upper support base is matched and provided with an upper conveyor; a driving device is arranged above the upper support base; the upper support base is provided with an upper pulley for matching with the driving device; the pulley is arranged around the upper support base by one lap; the base is provided with a lower pulley for matching with the upper support base; a chain is arranged between the upper pulley and the lower pulley; the chain is matched and provided with lifting plates; multiple sets of lifting plates are provided; the lifting plates are arranged at intervals; and the lifting plates are produced by adopting antiskid panels. The lifting plates are pulled through the chain to lift large objects; and the chain provided by matching with the lifting plates is used for stably conveying to improve stability of the device.

Description

technical field [0001] The invention relates to a load lifting device in the field of material transportation. Background technique [0002] The hoist is a large-scale mechanical equipment that is transported by changing the potential energy, such as mine hoist, dam hoist, etc. Broadly speaking, elevators, cranes, winches, stabilizers, cranes, hoists, etc. can all be called hoisting machines. Hoists; hoists generally refer to large-scale mechanical equipment with large power and strong lifting capacity; the transportation process is completed by dragging the flexible wire rope and the transported goods up and down by the power machinery. The wire rope is an indispensable and important part of the hoisting machinery. The main varieties are phosphating-coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, smooth steel wire rope, etc.; the traditional hoist has small load capacity, unstable lifting, and poor lifting effect.
