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.

This invention relates to the field of machining and assembly technology, and discloses an auxiliary disassembly device for cylinder liners. The device includes a mandrel with a tapered end, which is fitted inside a radially expandable elastic spring. At least one O-ring is fitted around the outer periphery of the elastic spring. A drive component is connected to the upper end of the mandrel, and an anti-rotation guide component is fitted in the middle of the mandrel. The mandrel is inserted into the cylinder liner of the cylinder block. Rotating the drive component clockwise drives the mandrel to move linearly axially. The engagement between the outer tapered surface of the tapered head and the inner tapered surface of the elastic spring forces the elastic spring to expand radially, pressing the O-ring against the inner wall of the cylinder liner. Pulling the drive component upwards moves the cylinder liner upwards with the mandrel, thereby removing it from the cylinder block. This invention, through the tapered mandrel and elastic spring structure, combines the lifting force with the radial expansion force, utilizing the controllable static friction generated between the O-ring and the inner wall of the cylinder liner to achieve non-destructive disassembly of the cylinder liner.
