The screw jack can be interconnected for multiple units. By combining two or more lifting jacks through couplings, drive shafts, and reversers, the simultaneous lifting of multiple units is achieved. Simply put, two units can be interconnected through two sets of couplings and a single drive shaft. Four-unit and eight-unit interconnections are also widely used, primarily for the simultaneous lifting or lowering of large platforms. A reverser is needed to change direction, ensuring the synchronization of multiple lifting jacks.
How to achieve the synchronization of output power among multiple screw jacks under the same conditions, with the requirement that the output directions of the screw jacks be opposite, and maintain zero error within milliseconds. This necessitates the precise calculation of the output frequency of the screw jacks. We summarize the following points, hoping they provide valuable reference:
Firstly: The screw jack selected must haveThe speed ratio and rotational speed of the elevator output, which lays the foundation for synchronization.
Next: a screw jack that needs to have both input and output capabilities.
In another scenario, you can use a synchronized device, such as a connecting rod or a synchronous sprocket. Generally, screw jacks are more suitable for this requirement. The output motor can only be one, which also allows for synchronization.
