Abstract

The invention belongs to the technical field of cranes, and particularly relates to a small crane for municipal engineering. The small crane comprises a first winding wheel, a heavy base, a vertical support, a transverse support, a fixed pulley fixedly installed on the upper surface of one end of the transverse support, a first steel wire rope, a second steel wire rope, a swing plate and the like,wherein an input gear rotates in a reciprocating mode through the reciprocating swinging of the swing plate, the input gear serves as a power source for a one-way transmission mechanism, an output gear can output power in a single rotating direction all the time, the output gear drives a second winding wheel through a second rotating shaft to wind the second steel wire rope, and the second steelwire rope lifts up a heavy object. After the input gear does not input power any more, the one-way transmission mechanism can be automatically self-locked, and therefore the safety of the small cranehoisting the heavy object is ensured. The small crane is simple in structure and has a good use effect.

Description

technical field [0001] The invention belongs to the technical field of hoisting machines, in particular to a small hoisting machine used in municipal engineering. Background technique [0002] At present, in municipal engineering in cities, small hoists are often used to carry or load and unload some small heavy objects that are difficult to carry by manpower. Most of the small hoisting machines are mainly driven by motors to hoist small heavy objects, but electric-driven small hoisting machines cannot be used in municipal areas without power supply. At this time, it is very suitable to use human-powered small hoisting machines. For ordinary small hoisting machines with manpower, many of them are hoisted by the telescopic principle of hydraulic telescopic rods, but the cost of using hydraulic telescopic rods is relatively high. In order to reduce the cost of the small manpower hoisting machine and achieve labor-saving effect at the same time, a small manpower hoisting machi...
