Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hoist hooks, in particular to a hoist hook state identification device. Background Art
[0002] The hoist hook is an important part of the hoist and is used for lifting and transporting materials. The design, manufacture and use of the hoist hook need to strictly comply with relevant safety standards and regulations to ensure workplace safety and work efficiency. In terms of design and manufacturing, the hoist hook needs to take into account factors such as its load-bearing capacity, stability, and durability. It is usually made of high-strength materials such as alloy steel, stainless steel, etc. to ensure that it can withstand the weight of the hoisted materials. In addition, the structure of the hook also needs to be reasonably designed to ensure that it will not cause safety hazards such as deformation or breakage during use.
[0003] The following problems exist: during the CDQ elevator's lifting operation of the coke tank, the elevator hook fails to safely hook the coke tank due to the tilting of the coke tank, deformation of the elevator hoist, and jamming of the elevator hoist. This causes an unbalanced load on both sides of the elevator, leading to the tilting of the coke tank, broken wire ropes, and the falling of red coke. These accidents not only seriously affect the safe production and operation of the CDQ system, but also cause serious damage to the on-site equipment, causing great economic losses to the company.
