Abstract

The invention belongs to the technical field of hoisting machines and particularly relates to a movable small hoisting machine for municipal projects. The movable small hoisting machine for the municipal projects comprises a first winding wheel, a heavy base, a transverse support, a fixed pulley, a second winding wheel, a rocker and the like. An input gear is made to rotate reciprocatingly by reciprocating swinging of a swinging plate. The input gear is adopted as the power source of a unidirectional transmission mechanism so that power can be output by an output gear in a single rotating direction from beginning to end. After power is not input by the input gear, the unidirectional transmission mechanism self-locks automatically, and safety when a heavy object is hoisted by the small hoisting machine is guaranteed. When the hoisting height of the heavy object needs to be readjusted in the process that the heavy object is put down, through resetting action of an unlocking mechanism, the unidirectional transmission mechanism is switched to a self-locking state process again from an unlocked state; friction braking still exists between a friction wheel and an arc-shaped braking pad;and it is prevented that the heavy object falls rapidly and damage is caused. After the unidirectional transmission mechanism is switched to the self-locking state again, and power is input again by the input gear, the unidirectional transmission mechanism gets back to work.

Description

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