A continuously holonomically lockable variable stiffness wire driven continuum robot
This invention relates to a lockable, variable stiffness linearly driven continuum robot, comprising a base, a linear guide propulsion module, coaxially fitted inner and outer tube continuum robot modules, and corresponding modules for driving, rotating, and locking the inner and outer tube continuum robot modules respectively. Both the inner and outer tube continuum robot modules consist of multiple joints connected in a serpentine structure via revolute joints, and include at least one locking joint. The locking module controls the rotation of the locking joint, causing its internal structure to engage a limiting block on the locking line, thereby fixing the length of the locking line from the base to the joint, achieving overall mechanical locking and stiffness enhancement of that segment of the robot's posture. This invention reduces the axial and radial dimensions at the joints, increases the range of robot stiffness variation and the robot's degrees of freedom, and adapts to internal surgical environments in confined spaces.

A prefabricated direct-buried heat-insulating pipe joint tensioning device
This invention relates to the field of pipeline connection technology, specifically to a prefabricated direct-buried insulated pipe joint tensioning device, comprising an implementation component, a locking component, a synchronization component, a compensation component, and an auxiliary pressure component. In this invention, the synchronization component ensures that the relative tensioning bands are tensioned synchronously, avoiding wrinkles caused by uneven tension on the left and right sides that could affect the final sealing performance. Furthermore, the elastic potential energy stored in multiple energy-storing springs during locking allows for real-time adjustment of the tension during cooling. The synchronization and compensation components simplify the tensioning and subsequent adjustment steps, ensuring effective tensioning while improving operational convenience. By using multiple circumferentially distributed tensioning bands for locking, a multi-joint fastening method is formed. An auxiliary pressure roller applies a combined force towards the center of the joint sleeve at connection section one and connection section two. Compared to existing single-joint locking methods, this results in more uniform locking and force distribution.
