Abstract
Description
Technical Field
[0001] This utility model relates to a hydraulic rolling cutter for flat tail ropes, specifically a device suitable for cutting and severing flat steel wire ropes (referred to as flat tail ropes) used for balancing vertical shaft hoisting, belonging to the field of mine hoisting technology. Background Technology
[0002] In a vertical shaft friction hoisting system for mines, the flat tail rope is suspended at the bottom of the hoisting container to balance the weight of the head rope. It is an important component of the vertical shaft friction hoisting system and is widely used.
[0003] To ensure the safety of the hoisting system, flat tail ropes must be replaced regularly in accordance with relevant mine safety regulations. Replacing flat tail ropes generally requires cutting and slitting operations, especially for older ropes which often need to be cut into multiple sections for storage and transportation. This cutting and slitting work is quite extensive.
[0004] Due to limitations in current technology and on-site environmental conditions, the cutting of flat-tailed ropes still largely relies on manual cutting methods such as flame cutting, high-speed sawing, and pliers, which are inefficient, time-consuming, and labor-intensive. In particular, the use of open flames or the generation of sparks during the cutting process poses significant safety risks to the mine and is strictly prohibited in environments containing explosive gases, such as coal mines.
[0005] Currently, hydraulic shears are commonly used to cut round steel wire ropes. This method typically operates on a single wire rope at a time, cutting only one rope at a time. However, flat-tail ropes are composed of multiple sub-wire ropes arranged in a rectangular pattern and sewn together with weft ropes. The hydraulic shears commonly used for cutting round steel wire ropes are unsuitable for cutting flat-tail ropes. Therefore, researching new, efficient, and safe cutting techniques, tools, or equipment suitable for flat-tail ropes in mine shaft hoisting systems is an urgent issue that needs to be addressed on-site. Summary of the Invention
