Description
Technical Field
[0001] The present invention relates to the technical field of lifting platforms, and in particular to a lifting device and mechanical installation equipment. Background Art
[0002] A lifting platform is a mechanical device used for vertical lifting to transport goods or equipment. It is commonly found in factories, warehouses, machinery installation and maintenance places, etc. It transfers heavy objects from one height to another through a stable lifting structure, greatly improving work efficiency. The lifting platform can be used for precise positioning of objects during equipment assembly, vertical transportation of heavy objects in the factory, or lifting workers and tools to a suitable height during equipment maintenance, avoiding the instability of traditional scaffolding. In addition, the platform can be equipped with electric, hydraulic or mechanical drive systems to meet the lifting needs in different environments. It is easy to operate and widely used in a variety of industries.
[0003] When the existing lifting device is at the lowest initial height, the angle between the axis of the support arm and the propulsion direction of the screw is very small and almost parallel, which leads to extremely high requirements for the propulsion force of the screw. In order to ensure that the lifting process can proceed smoothly, a certain angle is usually retained in the design. However, this approach limits the possibility of lowering the initial height of the lifting platform. Even if the stability of the equipment is improved by maintaining a certain angle, the driving force demand is still very high, especially when the equipment is started. This increases the energy consumption of the equipment operation and the performance requirements for the drive system. At the same time, the mobile structure of the existing lifting device cannot be retracted and is easily rusted and damaged if exposed for a long time.
[0004] Therefore, when the above-mentioned existing lifting device is at the lowest initial height, the angle between the axis of the support arm and the propulsion direction of the screw is very small and almost parallel, which leads to extremely high requirements for the propulsion force of the screw. In order to ensure that the lifting process can proceed smoothly, a certain angle is usually retained in the design. This approach places a high demand on the driving force when the equipment is started. At the same time, the mobile structure of the existing lifting device cannot be folded up, and it is easy to rust and cause jamming and damage when exposed for a long time. A lifting device and mechanical installation equipment can be designed to add an auxiliary rising mechanism and a retractable mobile mechanism, which can reduce the thrust demand and at the same time lower the initial height, improve the overall efficiency and flexibility of the equipment, and the retractable mobile mechanism can protect the mobile mechanism when it is not moving.
