Floating dock of modified structure

Abstract

The invention provides a floating dock of a modified structure, and belongs to the technical field of ships. The floating dock of the modified structure comprises a floating dock body, wherein a plurality of balance devices are arranged on the floating dock body, each balance device comprises two balance mechanisms and two installation grooves, the balance mechanisms are arranged in the corresponding installation grooves, each balance mechanism comprises a floating board, a first electric winch and two second electric winches, the floating boards are hinged to the bottoms of the installation grooves, the first electric winches are arranged on the bottoms of the installation grooves, an elongated opening is formed in the end, away from a corresponding hinged shaft, of each floating board, fixing shafts are arranged in the openings, pulleys are rotatably arranged on the fixing shafts, driving mechanisms capable of making the fixing shafts slide in length directions of the elongated openings back and forth are arranged in the floating boards, first steel ropes wound around reels of the first electric winches penetrate through the pulleys, and weights are fixedly arranged on the end portions of the steel ropes. The floating dock of the modified structure is simple in structure and has a good effect of preventing transverse inclination.

Description

technical field [0001] The invention belongs to the technical field of ships and relates to a floating dock with an improved structure. Background technique [0002] The floating dock has a huge concave-shaped cabin with walls on both sides and open front and rear ends. It is a trough-shaped flat-bottomed boat with a special structure. For the maintenance and construction of offshore ships, due to the large draft when the floating dock sinks, sufficient water depth is required, but the water depth in the offshore is relatively shallow, so it needs to be installed in a far sea area, and the wind and waves in the far sea area are relatively large, so the floating dock It will sway from side to side, and if there is a maintenance ship in the floating dock, it will cause the two to collide, causing certain marine accidents, and the structural design of the front and rear openings of the floating dock makes the floating dock's ability to resist wind and waves poor. [0003] In a...

[0002] The floating dock has a huge concave-shaped cabin with walls on both sides and open front and rear ends. It is a trough-shaped flat-bottomed boat with a special structure. For the maintenance and construction of offshore ships, due to the large draft when the floating dock sinks, sufficient water depth is required, but the water depth in the offshore is relatively shallow, so it needs to be installed in a far sea area, and the wind and waves in the far sea area are relatively large, so the floating dock It will sway from side to side. If there is a maintenance ship in the floating dock, it will cause the two to collide and cause certain marine accidents. Moreover, the structural design of the front and rear openings of the floating dock makes the floating dock's anti-wind and wave ability poor.

[0003] In addition, anchoring is usually used to limit the position of the floating dock. Due to the heavy weight of the anchor chain, when the anchor sinks to the bottom of the water, a long part of the anchor chain between the floating dock and the anchor is in a heaving state, which is vulnerable to wind and waves. Swing due to the impact of the floating dock, which will affect the working accuracy in the floating dock
