the glue injection cavity is filled with vulcanized rubber 6 through the glue coating hole 11 and the glue injection hole 2.
The bearing surface 5 is conical, and the outer side of the bearing part 7 is conical matched with the bearing surface 5.
The bearing surface 5 is step-shaped, and the outer side of the bearing part 7 is step-shaped matched with the bearing surface 5.
A wear-resistant sleeve 8 is arranged in the through hole, and a plastic-coated steel cable 10 is contacted with the wear-resistant sleeve 8; the wear-resistant sleeve 8 is made of an insulating material.
The upper end of the plastic-coated steel cable 10 is bound by the steel cable pressing buckle 9, and the steel cable pressing buckle 9 at the upper end of the plastic-coated steel cable 10 is arranged in the glue injection cavity.
The lateral part of connecting piece is provided with the opening, and the opening is through crossing gluey hole 11 and injecting glue cavity intercommunication, concreties in injecting glue cavity through opening and the vulcanite 6 of crossing gluey hole 11 pouring.
Referring to fig. 4 and 5, a coupling transmission sensor 12 and a first sensing unit 15 are arranged on the plastic coated steel cable 10, the sensing unit is arranged at the upper end of the coupling sensor, and the sensing unit is also connected with a second sensing unit 16 arranged on a buoy 14 through a cable 13.
The top end of the connecting piece is provided with a connecting hole 1, and the connecting piece is connected with the buoy 14 through the connecting hole 1.
The utility model discloses specific working process:
firstly, an internal bearing structure is processed, the plastic-coated steel cable 10 passes through a through hole on the bearing part 7, a wear-resistant sleeve 8 is arranged in the through hole, and the wear-resistant sleeve 8 is made of an insulating material with better wear resistance, such as DuPont plastic. The plastic-coated steel cable 10 is locked by a steel cable pressing buckle 9, and when the plastic-coated steel cable 10 is locked by a steel cable pressing buckle, the outer layer of the plastic-coated steel cable 10 is damaged by plastic coating, so that the sensing unit is arranged below the joint; then the inner bearing structure penetrates through the glue injection hole 2 of the bearing joint shell 4, bearing force is carried by the bearing surface 5, the plastic-coated steel cable 10 is tensioned, and then vulcanized rubber 6 is injected, so that the steel cable pressing buckle 9 damages the plastic-coated steel cable 10 and is wrapped by the vulcanized rubber 6, meanwhile, the inner steel core of the plastic-coated steel cable 10 cannot contact with seawater, and the vulcanized rubber 6 flows into the glue injection cavity below from the glue coating hole 11.
