Abstract

The light aluminum alloy chain block includes main body mechanism, ratchet spanner mechanism and driven chain wheel mechanism. The main body mechanism includes casing, screwed cover plate, upper lifting hook, non-return gear set and chain wheel set inside the casing, and cable clamping board assembly to avoid outer separation of the chain. The ratchet spanner mechanism has ratchet handle assembly fitted to the gear shaft. The present invention has simple and compact structure, light weight, no reverse turning, and flexible and light operation, and is suitable for overhead operation.

Description

technical field [0001] The invention relates to machinery manufacturing, in particular to a portable aluminum alloy lever hoist, which is used for lifting or tightening lines, and is especially suitable for high-altitude operations. Background technique [0002] At present, domestically produced lever hoists are mainly made of steel and iron, and the chains used are all ordinary chains with a diameter between 6mm and 10mm. There is no doubt that the tool has not achieved the desired effect in terms of operation or work efficiency. The application date is the "Level Hoist" of Chinese Utility Model Patent ZL03230717.9 on April 23, 2003 (the announcement number is CN2637460Y), which is composed of a casing, a sprocket shaft, a sprocket wheel, a handle assembly, and a brake assembly. , the reversing pawl is engaged with the reversing ratchet at the sprocket shaft end, and the sprocket shaft is still one with the sprocket, and the sprocket shaft end connects the left and right s...
