AI Technical Summary
Existing methods for measuring chain length have problems such as large measurement errors, the need for multiple people to cooperate, and the inability to guarantee that the chain is in a taut state.
An automatic length measuring device for chain assembly was designed. It uses a plug-in mechanism to connect with the chain traction end, and a translation drive mechanism to pull the chain into the material placement platform. A laser rangefinder and reflector are used to measure the chain length to ensure that the chain is in a taut state.
This improved the accuracy and efficiency of chain length measurement, saved labor, and reduced the need for manual operation.
