Problems solved by technology
Civilian elevators have high requirements for supporting facilities, and generally cannot be used for outdoor operations; cables are used for lifting, and cable breakage is prone to fall accidents. In addition, power failure during operation is not conducive to escape
Construction elevators are suitable for outdoor use, but steel pipe supports need to be erected. The construction is relatively complicated and the cost is high. At the same time, construction elevators are lifted by cables, and the cable breaks are prone to fall accidents, and the safety is not high.
In addition, if there is a power outage, it is not conducive to rescue at high altitudes, and it does not have the functions of crisis relief and escape
[0004] Due to the different outdoor operation scenarios, for example, in the field of electric power construction, it is necessary to use lifting and climbing equipment to work on high electric towers. Inconvenient; such as a fire scene, the normal channel is blocked, and there is no effective lifting equipment to assist rescue work; therefore, designing a safe lifting equipment with high safety, wide application range, and crisis relief and escape functions is an urgent breakthrough in the industry. problem

A safety lifting device of the present invention includes a carrier, an upper power component, a lower power component, a lifting component, an extension guide rail and an electric control component. The upper power component, the lower power component, the lifting component and the carrier realize linkage in the same direction. The above-mentioned lifting component is spirally matched with the extended guide rail; the electric control component is electrically connected with the power component, and the upper power component and the lower power component drive the lifting component to move up and down along the extended guide rail. It has the advantages of high safety, wide application range, crisis relief and escape functions. It belongs to the technical field of lifting equipment.
Description
technical field [0001] The invention belongs to the technical field of lifting equipment, and in particular relates to a safe lifting equipment with high safety, wide application range, crisis relief and escape functions; it can be used as outdoor construction climbing equipment, high-rise rescue (escape) equipment, fire escape ladder , the safe passage of old houses, and the use of elevators for people. Background technique [0002] Lifting equipment is a device that enables people or things to move back and forth between low and high places. The important indicators of lifting equipment are: 1. Safety; 2. Detachability; 3. Has the function of crisis relief and escape. [0003] At present, the common lifting mechanisms include civil elevators and building elevators. Civilian elevators have high requirements for supporting facilities, and generally cannot be used for outdoor operations; cables are used for lifting, and cable breakage is prone to fall accidents. In addition,...
