Crane for repairing ship

Abstract

The invention discloses a crane for repairing a ship. The crane comprises a side frame, a supporting device is fixedly connected with each side of the side frame, each supporting device comprises a fixed plate, one end of each fixed plate is fixedly connected to the corresponding side of the side frame, a top block is fixedly connected to the upper surface of each fixed plate, the top of each top block is in contact with the bottom of a corresponding movable plate, and the bottom of each movable plate is fixedly connected with one end of a spring. According to the crane for repairing the ship, through arrangement of the supporting devices, the hoisted ship can be pulled to be above the movable plates, then when the ship position goes beyond the movable plates, the movable plates are pulled to the original positions, and thereby the ship can be fixed better; the problem that in the repairing process, a ship cannot be fixed is solved, and the ship is prevented from shaking in the repairing process; through arrangement of electric extending-and-contracting rods and squeezing plates, after being placed to the right position, the ship is subjected to squeezing fixation through the squeezing plates, so that the ship is prevented from shaking in the repairing process.

Description

technical field [0001] The invention relates to the technical field of marine equipment, in particular to a crane for ship maintenance. Background technique [0002] Ship, the general term for all kinds of ships. Ships are means of transportation that can sail or berth in waters for transportation or operations, and have different technical performances, equipment and structural types according to different requirements for use. A ship is a man-made means of transportation that operates mainly in water. In addition, civilian ships are generally called ships, military ships are called ships, and small ships are called boats or boats, which are collectively called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that utilizes external or self-contained energy. The appearance is generally a streamlined envelope that is conducive to overcoming fluid resistance. The materials are constantly ...

AI Technical Summary

Problems solved by technology

Ships will use cranes during maintenance. At present, the existing cranes on the market can only lift the ship when repairing the ship, and cannot fix the ship. Fixing will cause the ship to shake due to the force, which will affect the progress of maintenance and reduce work efficiency, and maintenance during shaking will cause certain injuries to maintenance personnel
