Abstract

The invention belongs to the technical field of hoisting machines, in particular to a movable small hoisting machine used in municipal engineering. The movable small hoisting machine comprises a firstwinding wheel, a heavy base, a horizontal bracket, a fixed pulley, a second winding wheel, a rocker and the like. A swing plate does reciprocating swing to enable an input gear to reciprocally rotate, the input gear acts as a power source of a one-way transmission mechanism, and therefore an output gear can always output power in the single rotation direction; and after the input gear no longer inputs power, the one-way transmission mechanism conducts automatic locking, and safety of the small hoisting machine during lifting of heavy objects is ensured. In the process that the heavy objects are placed down, when the lifting height of the heavy objects needs to be readjusted, resetting action of an unlocking mechanism enables the one-way transmission mechanism to switch from the unlockingstate to the self-locking state again, a friction wheel and a curved brake pad are still in friction brake, and damage caused by rapid falling of the heavy objects is prevented; and after the one-waytransmission mechanism is switched back to the self-locking state, the one-way transmission mechanism starts to work again after power is input into the input gear again.

Description

technical field [0001] The invention belongs to the technical field of hoisting machines, in particular to a small movable 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 hoisti...
