Abstract

The invention provides a coiling block. The coiling block or a coiling block shaft of the coiling block is provided with a plurality of rope blocking plates. At least one rope blocking plate is provided with a hole for a steel wire rope to pass through. The coiling block or the coiling block shaft of the coiling block is provided with a connecting end supporting base of the steel wire rope; the connecting end supporting base of the steel wire rope is only used for fixing and winding the end steel wire rope by a plurality of circles; and no steel wire ropes are stacked on the connecting end supporting base of the steel wire rope in a winding manner.

Description

technical field [0001] This application belongs to a lifting device. Background technique [0002] The main function of the existing lifting equipment such as the hoist is to lift and pull the heavy object to go up or down. If it hovers in the air, it depends on the braking device of the reel to stop. The existing regulations require that the wire rope of the hoist cannot be pulled completely. It must be ensured that the steel wire rope coiled on the drum is kept for at least 3 turns to ensure the safety of the stress-bearing end. If all the steel wire rope coiled on the drum is released, the steel wire rope will be fixed and connected to the pressure plate on the drum through the pressure plate. And the anchor bolts are very vulnerable to the radial tension, and they are peeled off the reel one by one to cause danger. It is precisely because of the above reasons that the steel wire rope extending from the fixed end of the wire rope is at least wound on the reel and retained...

AI Technical Summary

Problems solved by technology

Since the wire rope wound on the reel is not allowed to be fully rotated and extended out of the reel, the reel is subjected to a large torque when the wire rope hoists heavy objects and hovers in the air, and the brake must be used to ensure that the heavy objects Hovering in the air, so the hoist cannot bear a large load, especially for a long time to hang heavy objects in the air, especially because the braking and parking device of the hoist is prone to failure, so the existing regulations prohibit the use of the hoist to lift people Therefore, it cannot be used as a stressed steel wire rope or a safety rope for the hanging basket

In addition, the existing steel wire rope wound on the reel is not allowed to be fully released, and at least three turns should be reserved. On the above-mentioned reserved at least three turns of the steel wire rope, there are also multiple layers of steel wire ropes, which is very easy to damage the wire rope at the end part. Damaged and broken wire rope at the end
