Heavy steel wire rope drum

Abstract

The invention discloses a heavy steel wire rope drum, which comprises a support plate, wherein a bottom disc is arranged above the support plate. A plurality of uniformly distributed rollers are arranged between the support disc and the bottom disc. A steel wire rope drum is welded in the centre of the upper surface of the bottom disc and a mandrill penetrates through the steel wire rope drum. The lower end of the mandrill penetrates through the bottom disc and is inserted into the support plate while the upper end penetrates through the steel wire rope drum. The upper end of the mandrill exposed out of the steel wire rope drum is sleeved with a shaft sleeve which is connected with a plurality of bended brackets. One end of the horizontal part of each bended bracket is connected to the shaft sleeve while the other end is connected with the vertical part of the bended bracket. The invention has the advantages of simple structure, large bearing capacity, stable operation, low cost and high safety performance.

Description

technical field [0001] The invention relates to a heavy-duty steel wire rope drum. Background technique [0002] At present, with the rapid development of my country's ocean engineering, heavy-duty steel wire ropes are widely used, and the weight of a single steel wire rope drum generally reaches more than 100 tons. Due to the limitation of the size of the shaft center hole of the steel wire rope drum, in the previous rope threading device, the horizontal mandrel had to bear the weight of the drum, which could only meet the drum with a total weight of less than 80 tons. In the initial stage, the friction between the reel and the deformed horizontal mandrel is serious, resulting in difficult rotation and low efficiency. In the later stage of threading, after the weight of the reel is reduced, the rotation speed is too fast and uncontrollable, and the rotation inertia leads to too much rope, which is dangerous. At the same time, the reel and rope are easily damaged, and the m...

Problems solved by technology

Due to the limitation of the size of the shaft center hole of the steel wire rope drum, in the previous rope threading device, the horizontal mandrel had to bear the weight of the drum, which could only meet the drum with a total weight of less than 80 tons. The friction between the reel and the deformed horizontal mandrel in the initial stage is serious, resulting in difficult rotation and low efficiency

In the later stage of threading, after the weight of the reel is reduced, the rotation speed is too fast and uncontrollable, and the rotation inertia leads to too much rope, which is dangerous. At the same time, the reel and rope are easily damaged, and the maintenance frequency is high, and the cost Big
