Abstract

The invention discloses a small crane. The small crane comprises a lifting arm, a lifting rope, a pulley, a lifting basket, an electric lifting device, a lifting arm mounting structure and a lifting arm support structure; the back end of the lifting arm is fixed on a wall through the lifting arm mounting structure; the lifting arm is connected with the lifting arm support structure; the lifting arm support structure is fixed on the wall; one end of the pulley is connected with the electric lifting device through the lifting rope, and the other end of the pulley is connected with the lifting basket; the front end of the lifting arm is downwards inclined, and is connected with an arc guide device; pulley rails are arranged on the lifting arm and the arc guide device; and the pulley is pulledby the electric lifting device to pull the lifting basket to move along the pulley rails. The small crane is simple in structure, lower in cost and convenient to operate and install. A traditional horizontal lifting arm structure is changed to an inclined structure; and the pulley is added above the lifting basket, so that the traditional lifting link is changed from two steps of upward verticalto horizontal to one step of round angle transition to horizontal after vertical ascending.

Description

technical field [0001] The invention relates to a small hoist, which belongs to the field of mechanical equipment. Background technique [0002] With the improvement of people's living standards, consumption power increases, and urbanization accelerates. It is time-consuming and inconvenient for high-rise residents to pick up and deliver objects. In response to this phenomenon, the present invention simplifies the structure of the boom and simplifies the installation steps, thereby reducing the cost and difficulty of installation and operation, and providing a simple way for high-rise residents to pick up objects. At present, need a kind of simple in structure on the market, cost is low, installation, simple self-use small balcony hoisting machine of operation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a small hoist that is safe, stable, easy to install, easy to operate and highly practical. [0004] T...
