Multi-rope friction type lifter and first rope replacing method thereof

Abstract

The invention discloses a multi-rope friction type lifter and a first rope replacing method thereof. The multi-rope friction type lifter comprises a friction wheel, a balance hammer, a cage, a lifting rope, a steady vehicle and a guide bracket; the balance hammer is arranged below the balance hammer; the cage is arranged below the friction wheel; the lifting rope comprises first ropes and a tail rope; the first ropes are wound on the friction wheel, and one end of each first rope is connected to the upper part of the cage, and the other end of each first rope is connected to the upper part of the balance hammer; the two ends of the tail rope are separately connected to the lower part of the cage and the lower part of the balance hammer separately; the plurality of the first ropes are arranged side by side; the steady vehicle comprises a rope winding wheel; a baffle plate extending in the circumferential direction of the rope winding wheel is arranged on the peripheral surface of the rope winding wheel for axially dividing the rope winding wheel into two rope winding wheel sections suitable for winding a to-be-replaced new rope; the guide bracket is arranged above the friction wheel; and two guide slide wheels which are in one-to-one correspondence to two rope winding wheel sections are arranged on the guide bracket. According to the embodiment of the invention, the multi-rope friction type lifter can improve first rope replacing efficiency and first rope replacing effect.

Description

technical field [0001] The invention relates to the technical field of mining, and more specifically, to a multi-rope friction hoist and a head rope replacement method for the multi-rope friction hoist. Background technique [0002] The multi-rope friction hoist uses the friction between the head rope and the drum liner to realize the function of lifting and lowering heavy objects. When one of the first ropes is corroded, worn, broken, or its service life reaches the requirements of the "Safety Regulations for Metal and Nonmetal Mine", all the first ropes must be replaced at the same time to maintain the same working conditions for each first rope. Therefore, the first rope replacement work of the multi-rope friction hoist is quite frequent. [0003] The head rope replacement method adopted by the multi-rope friction hoist in the related art is: the new steel rope is wound and fixed on the original head rope, and then the original head rope is used as a guide, and the head ...

Problems solved by technology

[0003] The head rope replacement method adopted by the multi-rope friction hoist in the related art is: the new steel rope is wound and fixed on the original head rope, and then the original head rope is used as a guide, and the head rope is lowered to the bottom of the well for replacement. If there are several first ropes, several operations need to be carried out. The operation time is long, and it needs to cross the mine and the underground. There are dangers of new and old steel ropes being entangled with each other, parallel operation, and falling objects.
