Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hoisting chain production line, concretely to a quick replacement and maintenance device of hoisting chain production line. BACKGROUND

[0002] The hoisting chain production line, also known as a hoisting chain conveying system, is an automated equipment for material handling, widely used in industrial production lines, especially in situations where materials need to be lifted vertically or obliquely. It connects with accessories (such as lifting hooks, pallets, shelves, etc.) through chains to form a closed-loop conveying system, lifting materials from one location to another, usually used to lift materials to higher locations or transport materials between different production stations.

[0003] A patent with the announcement number CN201375996Y discloses a steel pipe rolling production line hoisting chain chain misalignment adjuster, which includes a filler block, two locking plates, a locking bolt, and a locking handle. One side of the filler block is a convex round surface, and the other side is a circular arc surface. Two locking plates are arranged on both sides of the filler block. A screw hole is provided at the center of the lower end of one locking plate, and the locking bolt is screwed into the screw hole. The locking handle is arranged at one end of the locking bolt. This adjuster can quickly adjust the hoisting chain after misalignment, reducing labor intensity, improving repair efficiency, and avoiding safety hazards during the resetting process of the hoisting chain.

[0004] However, the above-mentioned steel pipe rolling production line hoisting chain chain misalignment adjuster is not convenient for disassembling and replacing the sprocket and chain. The sprocket and chain are used for lifting materials in the hoisting chain, so they need to be regularly maintained or replaced. The inconvenience of disassembling and replacing the sprocket and chain requires maintenance personnel to spend more time operating, which increases the downtime of the production line, reduces production efficiency, and cannot conveniently control the tension of the chain during daily use, so maintenance personnel can only rely on manual adjustment, which requires more frequent inspection and adjustment. Overly frequent manual adjustment not only wastes time but also easily leads to equipment failure due to improper adjustment. UTILITY MODEL CONTENTS
