technical field

The invention relates to the technical field of hoisting slings, in particular to a fast hoisting sling for large-scale glass-lined reactors and a method of use.

Background technique

Special slings such as hooks, wire ropes, and chains are commonly used in the spreader. Lifting suction cups, clamps and forks can be used as special spreaders on the crane for a long time, and can also be used as replaceable auxiliary spreaders hanging on the spreader. Temporary use on the hook, often used in warehouses and storage yards of various types of goods, to improve work efficiency. The spreader for grabbing bulk materials is generally a grab with jaws that can be opened and closed, and electromagnetic chucks can also be used to absorb magnetic properties such as metal chips. Material, the commonly used spreaders for lifting fluid materials are buckets and hanging tanks. Generally, molten steel or chemical solutions are discharged by tilting or bottom plugging, and fluid materials such as concrete are discharged by opening the bottom door of the hanging tank.

In this utility model, the semi-circular ring is then placed on the reactor body and moved to the bottom of the support seat, and the two semi-circular rings are combined to form a complete suspension ring, and then the two semi-circular rings are aligned again through the steering block, threaded rod, groove and pressing block. The semi-circular ring is used to limit and fix the reactor body, so that the reactor body can be lifted by connecting the lock column on the hanging plate with the hoist. Stable and reliable, convenient for users to use.

However, it still has the following shortcomings in the process of practical application:

Second, the glass-lined reactor is easy to collide with foreign objects during hoisting, causing damage. Because the above-mentioned comparison documents are not installed during the hoisting process, no protective mechanism is installed, so the glass-lined reactor is easy to collide with foreign objects during the hoisting process, causing damage .

Third, when the entire spreader is in contact with the ground, it is easy to cause damage due to impact. Because the above reference document does not set a buffer and shock absorption mechanism for the entire spreader, it is easy to cause damage due to impact when the spreader is in contact with the ground.
