A hoisting cargo posture adjustment device

Abstract

The invention belongs to the technical field of hoisting equipment, and relates to a device for adjusting the posture of hoisted goods. When hoisting goods on the base, actively adjust the posture of the hoisting goods so that the hoisting goods and the base are always kept parallel during the hoisting process, so as to avoid local contact between the hoisting goods and the base, causing damage to the hoisting goods and the base, especially suitable for offshore hoisting In the case of operations and offshore platform replenishment operations, no additional manpower and material resources are required, which reduces the cost of cargo hoisting, increases the efficiency of cargo loading and unloading, and ensures the safety of personnel; it has a simple structure, scientific and reasonable principles, convenient operation, and good practicability. The utility model has the advantages of friendly environment, strong versatility, safety and reliability, and is easy to popularize and use.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of hoisting equipment, and relates to a device for adjusting the attitude of hoisted goods, which can adjust the attitude of hoisted goods when hoisting goods on inclined, uneven or unstable bases, make the hoisted goods parallel to the base, and improve the safety of hoisted goods and work efficiency, especially suitable for offshore hoisting operations and offshore platform replenishment operations. [0003] Background technique: [0004] When hoisting cargo on an inclined, uneven or unstable base, cargo damage, long hoisting time, and a large amount of labor often occur, especially when hoisting operations and offshore platform replenishment operations are performed at sea, the ship will appear under the action of waves. Rolling, pitching, rising and sinking movements are not conducive to the implementation of hoisting operations and affect follow-up work: the rolling and pitching movements of the ...

Problems solved by technology

[0004] When hoisting cargo on an inclined, uneven or unstable base, cargo damage, long hoisting time, and a large amount of labor often occur, especially when hoisting operations and offshore platform replenishment operations are performed at sea, the ship will appear under the action of waves. Rolling, pitching, rising and sinking movements are not conducive to the implementation of hoisting operations and affect follow-up work: the rolling and pitching movements of the ship cause one side of the hoisted cargo to be suspended, and the other side is in contact with the deck of the ship, and the contact area is less than The area where the lifting cargo is in contact with the deck of the ship as a whole increases the local stress on the deck of the ship; the upward movement of the ship causes the hoisting cargo being lowered to collide with the rising ship; Suspension in the air will cause a huge change in the tension of the sling; these situations will lead to local damage to the hull and damage to the hoisted cargo, resulting in economic losses and even casualties

At present, in order to prevent the occurrence of the above situation, a passive method is usually adopted when carrying out hoisting operations and offshore platform replenishment operations at sea, manually laying square wood, planks or steel plates on the deck of the ship to increase the distance between the hoisting goods and the ship. The contact area of ​​the deck reduces the local stress. This method consumes manpower, wastes materials, reduces hoisting efficiency, increases the cost of loading and unloading cargo, and has potential safety hazards, which are prone to personnel safety accidents.
