Abstract

The invention belongs to the technical field of hoisting machines, and particularly relates to a small hoisting machine used in municipal engineering. The small hoisting machine 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 the reciprocating swing movement of the swing plate enables an input gear to rotate in a reciprocating mode, the input gear is used as a power source of aone-way transmission mechanism, so that the output gear can output power in a single rotating direction all the time, then the output gear drives a second winding wheel to enabled the second steel wire rope to be wound around the second winding wheel through a second rotating shaft, and the second steel wire rope lifts a heavy object; and after the input gear is no longer input with power, the one-way transmission mechanism can automatically self-lock, so that the safety of the small hoisting machine for hoisting the heavy object is guaranteed. According to the machine, the structure is simple, and a better use effect is achieved.

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...
