Problems solved by technology

The existing method of replacing the head rope and tail rope of the vertical shaft generally adopts the method of importing the belt rope from the underground to the top, and the tail rope head needs to be made at the bottom of the well. The operating environment is harsh, the safety is poor, and the operation efficiency is low and the rope replacement period is long.

Embodiment Construction

[0057] 1. Preparatory work for the replacement of the first rope:

[0058] 1. First transport the two new first ropes twisted in opposite directions with steel wire ropes to the east side of the wellhead of the shaft, and fix one end of the two new first ropes with steel wire rope buckles respectively.

[0059] 2. Weld a φ108 steel pipe at the lower end of the I-beam on the east side of the counterweight at the wellhead, and weld 2 U-shaped steel bars on the φ108 steel pipe.

[0060] 3. Set 2 rope buckles under the platform of the lower sky wheel, which are used to hang 2 1t hand chain hoists and 2 pairs of veneer clips. A tight rope. One 3t chain hoist and one pair of veneer clips are respectively fixed on the east and west sides above the upper sky wheel, and one 3t chain hoist and one pair of veneer clips are respectively fixed on the east and west sides above the lower sky wheel, which are used to hold the reel The new ropes on both sides are hoisted to ensure the operat...

Abstract

The present invention relates to a method for changing a head rope and tail rope for a shaft, including the steps of changing the head rope and changing the tail rope; the step of changing the head rope includes the steps such as providing a new rope from a balance weight side wellhead to a cage side wellhead, separating the new head rope temporarily, providing a new rope below the wellhead, carrying out balance weight side heading and carrying out cage side heading; the time for changing the head rope and tail rope is significantly shortened, and vertical deviation of a board during driving is relieved since head rope changing sequence is changed; the tail rope is changed by winding stably at the wellhead and paying off from top to bottom, all rear heads of the tail rope are manufactured on a ground, staff is avoided being in a severe environment when making rope tail heads at the bottom, and operation safety is improved. The method also provides reduced continuous operation intensity for workers and better coordinated production.

Description

technical field [0001] The invention relates to a method for replacing head ropes and tail ropes in a shaft. Background technique [0002] With the increasingly severe operating situation of the gold mining industry, the time and safety performance standards for upgrading the system maintenance are getting higher and higher. The existing method of replacing the head rope and tail rope of the vertical shaft generally adopts the method of importing the belt from the bottom to the top, and the tail rope needs to be made at the bottom of the well. The operating environment is harsh, the safety is poor, and the operation efficiency is low and the rope replacement period is long. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for replacing the head rope and the tail rope of a shaft, which improves the operating environment and improves the rope changing efficiency. [0004] For solving above technical scheme...
