Self-lifting loading device

Abstract

The elevator includes one support comprising two symmetric pieces, one driven double sprocket and one driving double sprocket separately in the upper part and the lower part, one ring double chain between the driven double sprocket and the driving double sprocket, one chain tightener, one crawling double sprocket meshed to the inner ring of the ring double chain and with arc chute, one crawling rope between the ring double chain and the arc chute of the crawling double sprocket, one rope guiding wheel in top, one sling in the lower part, and one driving mechanism to drive the driving double sprocket. The elevator can elevate article from ground to required height, and has smart structure, flexible use, high efficiency and high safety.

Description

Technical field [0001] The invention relates to a load carrying device with a lifting function. Background technique [0002] At present, there are many lifting devices with lifting functions, such as cranes, hoisting machinery, cranes, lifting pulleys (sets), etc., but these lifting devices need to be used in specific occasions, sometimes limited by environmental conditions, the existing lifting loads The device cannot be used. For example, if air conditioners are currently installed in homes or offices, most of the outdoor units are manually pulled to the installation position with ropes, and solar energy is installed on the top of the building, and it is also manually pulled to the roof with ropes, which is time-consuming and laborious. There are also potential safety hazards, especially when installing outdoor units outside residential buildings with anti-theft windows and on the gables of the buildings, it is even more difficult or even impossible to install. Summary of the...

[0002] At present, there are many load-carrying devices with lifting functions, such as cranes, hoisting machinery, cranes, lifting pulleys (groups), etc., but these lifting load-carrying devices need to be It is used in specific occasions, sometimes limited by environmental conditions, the existing lifting load-carrying device cannot be used

For example, if an air conditioner is installed in a home or office, the outdoor unit is usually manually pulled to the installation position with a rope, and the solar energy is installed on the top of the building, which is also time-consuming and labor-intensive. There are also potential safety hazards, especially when installing outdoor units outside residential buildings with anti-theft windows and on the gable walls of buildings, it is even more difficult to install, or even impossible to install.
