A tightening mechanism for a boom hole drilling installation robot
This utility model discloses a tightening mechanism for a boom drilling and installation robot, relating to the field of boom installation technology. It includes a limiting sleeve for boom assembly, with one end face recessed axially to a certain depth to form a limiting groove for accommodating a nut. The shape of the limiting groove matches the shape of the nut to prevent rotation and limit its movement. When the limiting sleeve is driven to rotate around its axial direction, the limiting groove restricts the nut's rotation. The limiting groove on the limiting sleeve precisely matches the nut's shape, applying radial limiting force through geometric constraints to ensure the nut remains synchronized with the limiting sleeve during rotation. Compared to the shortcomings of existing technologies where manual tightening with a wrench requires a large operating space and insufficient tightening force, this tightening structure uses a coaxial drive of the limiting sleeve, which does not occupy a large horizontal operating space and is suitable for areas with dense pipelines.
