AI Technical Summary

Technical Problem

The existing hoisting device has a non-adjustable crossbeam length, which means it can only be used for engine blocks within a specific diameter range, limiting the installation of cylinder blocks of different lengths. The operation is also cumbersome and inflexible.

Method used

An engine block hoisting device was designed, comprising a base plate, a support assembly, a lifting assembly, and a hoisting assembly. The spacing between the crossbeams is adjusted by a motor and a worm gear mechanism, and combined with an electric push rod and a pulley system, it can be adapted to cylinder blocks of different specifications.

Benefits of technology

It enables flexible lifting of engine blocks of different specifications, improves the adaptability and versatility of the lifting device, and simplifies the operation steps.
