Abstract

Anchoring systems can be applied to connect a robotic system with its power supply structure (for example, umbilical cables), and then separate the same into several modules, each containing a pair of anchors. A sleeve is tensioned, by pulling the ring against its stop and, thus, performing a self-locking. The self-locking occurs because the friction force generated at the lace interface is greater than the sleeve tensioning force. In addition, the mesh is tightened by threading the stop of the ring in the house of the ring. The anchoring systems can be applied to any part of the robot and as many times as necessary, not being limited to the connection with the umbilical.

Claims (15)

1. A system to anchor self-locking woven fiber sleeves, the system comprising:

a woven sleeve having a first segment and a second segment opposite the first segment, wherein the first segment comprises a first anchoring system and the second segment comprises a second anchoring system,

wherein the first anchoring system comprises:

a ring;

a ring house having an outer surface and threads defined along the outer surface; and

a ring stop having an inner surface and threads defined along the inner surface of the ring stop, the threads along the inner surface configured to mate with the threads along the outer surface of the ring house,

wherein the ring is between the ring house and the ring stop when the first anchoring system is assembled, and

wherein the second anchoring system comprises:

an inverted ring;

an inverted ring house; and

an inverted ring stop, wherein the inverted ring is between the inverted ring house and the inverted ring stop when the second anchoring system is assembled.

2. The system according to claim 1 , wherein the first segment of the woven sleeve laces the ring such that, when the woven sleeve is tensioned, the first segment of the woven sleeve pulls the ring against the ring stop and becomes locked.

3. The system according to claim 2 , wherein an initial friction force is generated in the system by tightening the woven sleeve and threading the ring stop in the ring house.

4. The system according to claim 1 , wherein, in the second anchoring system, when the woven sleeve is tensioned, the woven sleeve pulls the inverted ring against the inverted ring house and becomes locked.

5. The system according to claim 1 , wherein, in the first anchoring system, initial tightening is done by threading the ring stop and, in the second anchoring system, initial tightening is done by tightening one or more screws extending between the inverted ring house and the inverted ring stop.
