An ultra-deep vertical shaft large-load spiral winding friction lifting system and method

Abstract

The invention discloses an ultra-deep vertical shaft high-load spiral winding friction hoisting system and method. The ultra-deep vertical shaft high-load spiral winding friction hoisting system comprises two movable motors, two bearing pedestals horizontally moving along the axes of transmission bearing pedestals with spiral grooves, the two fixedly-installed transmission bearing pedestals with the spiral grooves, a spiral friction roller matched with the two transmission bearing pedestals with the spiral grooves, and a plurality of sections of hoisting steel wire ropes wound on a groove of the spiral friction roller. The two motors drive the spiral friction roller to rotate through a speed reducer, the spiral friction roller is supported by the bearing pedestals on the two sides of a rotary friction roller, the steel wire ropes wound on the spiral friction roller are wound and hoisted along the groove of the spiral friction roller through the friction force between the steel wire ropes and the spiral friction roller, the four sections of steel wire ropes are lifted or placed down at the same time, and the spiral friction roller makes axial movement along the transmission bearingpedestals with the spiral grooves while the steel wire ropes are hoisted. The defects that when a friction hoisting mode is adopted in an ultra-deep vertical shaft, the stress value of the junction ofsteel wire ropes and a container fluctuates largely, and when a winding hoisting mode is adopted, the steel wire ropes are prone to being damaged and broken as being wound around a roller too much are overcome.

Description

technical field [0001] The invention belongs to the technical field of shaft lifting, and in particular relates to a large-load spiral winding friction lifting system and method for an ultra-deep shaft, which is a large-load spiral friction lifting system and method based on a combination of winding and friction lifting, and is especially suitable for In the case of a large lifting force required in the ultra-deep shaft hoisting system. Background technique [0002] There are two main ways to lift the shaft when lifting the shaft. One is friction lifting, which lifts heavy objects by the friction between the lifting wire rope and the drum. This lifting method fluctuates in the stress value at the connection between the lifting wire rope and the container. Larger, and the deeper the mine, the greater the fluctuation value of the static stress; the other is the winding hoist, for the ultra-deep vertical shaft, the steel wire rope on the drum will be wound into many layers, and...

Problems solved by technology

[0002] There are two main ways to lift the shaft when lifting the shaft. One is friction lifting, which lifts heavy objects by the friction between the lifting wire rope and the drum. This lifting method fluctuates in the stress value at the connection between the lifting wire rope and the container. Larger, and the deeper the mine, the greater the fluctuation value of the static stress; the other is the winding hoist, for the ultra-deep vertical shaft, the steel wire rope on the drum will be wound into many layers, and the multi-layered steel wire rope is easily damaged damage, and the terminal load cannot be too large; therefore, this lifting method will also be greatly limited in the lifting force and wire rope life in the ultra-deep shaft hoisting system, and there is no other better lifting solution at present
