Description

Flat tail rope hydraulic rolling shear Technical Field The utility model relates to a hydraulic rolling shear for a flat tail rope, in particular to a device for cutting and cutting a flat steel wire rope (called the flat tail rope for short) for lifting balance of a vertical shaft, and belongs to the technical field of lifting of the vertical shaft. Background In the mine vertical friction lifting system, the flat tail rope is hung at the bottom of the lifting container and used for balancing the weight of the lifting head rope, and the flat tail rope is an important component of the vertical friction lifting system and is quite widely applied. In order to ensure the safety of the hoisting system, the flat tail rope must be replaced periodically according to the regulations related to mines. When the flat tail rope is replaced, the flat tail rope is generally required to be cut, and particularly the old flat tail rope is often required to be cut into a plurality of sections so as to be stored and transported, and the cutting and cutting operation of the flat tail rope is very large. Because of the limitations of the prior art means and the on-site environmental conditions, the cutting operation of the flat tail rope still mostly adopts common operation methods of manual cutting, such as flame gas cutting, high-speed sawing, tool pliers cutting and the like, and has low operation efficiency, time and labor waste. In particular, the use of open fires or sparks during cutting can create a significant safety risk for mines, which is strictly prohibited in coal mines containing explosive gases and the like. At present, the cutting and cutting of round steel wire ropes is usually carried out by adopting a hydraulic shear, and the method generally can only work on one steel wire rope at a time. The flat tail rope is formed by arranging a plurality of sub steel wire ropes in a rectangular shape and is sewn into a whole by weft ropes. The hydraulic scissors commonly used for cutting round steel wire ropes cannot be suitable for cutting operation of flat tail ropes. Therefore, the research on a novel technical method and tool or equipment for efficiently and safely cutting and breaking the flat tail rope of the mine vertical shaft lifting system is a subject which needs to be solved on site urgently.
