Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, in particular to a drum lifting device. Background Art

[0002] The drum lifting device is a common driving mechanism in lifting machinery. It usually contains one or more drums (reels) on which wire ropes, chains or other lifting media are wound. When the drum rotates, the lifting platform is lifted and lowered by retracting and releasing the wire rope or chain. In the lifting platform, the drum lifting device is usually used in conjunction with motors, reducers, brakes and other components to provide stable lifting power and precise control. The lifting platform can be raised and lowered by controlling the forward and reverse rotation of the motor; and the brake is used to quickly stop the movement of the lifting platform when necessary to ensure safety.

[0003] During the operation of the drum lifting device, the motor provides driving force to cause the drum to roll, and then the lifting platform is lifted and lowered by retracting and releasing the wire rope or chain. However, the driving motor will inevitably come into contact with the outer shell of the device during operation, which will generate excessive vibration and noise, affecting the stability of the entire drum lifting device.

[0004] Therefore, it is necessary to design a reel lifting device to solve the above-mentioned problems. Utility Model Content
