Description

Technical Field

[0001] The utility model relates to the technical field of aluminum coil hoisting, in particular to a lifting device for aluminum coils on a machine. Background Art

[0002] Aluminum coils are widely used in electronics, packaging, construction, machinery and other fields. There are many aluminum coil production companies in my country. According to the different metal elements contained in the aluminum coils, aluminum coils can be roughly divided into 9 major categories, that is, they can be divided into 9 series. When lifting aluminum coils, lifting equipment is required.

[0003] After extensive searching, we discovered prior art publication number CN214031412U, which describes an aluminum coil lifting device comprising a boom and elbows detachably connected to each end of the boom. The ends of the two elbows, remote from the boom, are each connected to a flexible lifting rope, each having a flexible protective sleeve and a lifting eye at the end remote from the elbow. The present invention has the beneficial effect of simplifying the structure and making it easy to manufacture, thereby improving the safety of the lifting operation and ensuring the quality of the aluminum coil. However, according to the technical problem raised by the aforementioned utility model, aluminum coils are typically lifted directly using nylon rope or steel wire rope. Because nylon rope or steel wire rope is flexible and the aluminum coil is relatively heavy, gravity forces the ends of the nylon rope or steel wire rope toward the aluminum coil, causing friction with the end face of the aluminum coil, resulting in damage to the nylon rope or steel wire rope and even bruising the end face of the aluminum coil, thereby affecting the safety of the lifting operation and reducing the quality of the aluminum coil. Further improvements are needed to address this issue.

[0004] Therefore, it is necessary to provide a lifting device for aluminum coils to solve the above technical problems. Utility Model Content

[0007] Preferably, an adjustment mechanism is vertically installed on the top surface of the hanging tube, a threaded adjustment tube is provided inside the adjustment mechanism, a threaded adjustment rod is spirally connected inside the threaded adjustment tube, and a hanging ring is provided on the top of the threaded adjustment rod.

Compared with the prior art, this type of aluminum coil lifting device is convenient for limiting the ends of the aluminum coil when lifting the aluminum coil by setting a lifting barrel, a two-way screw rod, a first threaded sleeve, a second threaded sleeve, a first limit rod and a second limit rod, so as to avoid the steel wire rope from causing damage to the two ends of the aluminum coil.
