A construction technique for leading ropes in the process of replacing mine hoisting ropes

Abstract

The invention discloses a construction technique for pulling ropes in the process of replacing mine hoisting ropes. The steps include: stopping container II at the wellhead platform, and stopping container I on the other side at the bottom platform of the well; leading the pulling rope to a high At the wellhead, connect the head of the traction rope to the old rope that needs to be replaced; disconnect the old rope that needs to be replaced from the container II; run the hoist forward, lower the container II, and at the same time, pull the traction The rope is continuously recovered to the outside of the wellhead, and the disconnected old rope is led to the outside of the wellhead. When the connection between the traction rope and the old rope falls to the position of the wellhead, the hoist stops running; the connection between the rope end of the traction rope and the old rope is released, and the traction The rope withdraws and the leading rope is completed. The rope leading construction process of the present invention can efficiently and conveniently thread the old rope that needs to be replaced into the rope changing device, shortens the rope leading time of mechanical rope changing, and not only provides a premise guarantee for the subsequent process of the whole rope changing, but also It can effectively improve the efficiency of the whole rope changing construction.

Description

technical field [0001] The invention relates to the technical field of mine hoisting, in particular to a construction technique for leading ropes in the process of replacing the first rope of mine hoisting. Background technique [0002] As an important form of shaft hoisting, friction lifting has been used more and more. In order to ensure the safety and reliability of friction lifting, replacing the lifting rope is an important task to ensure the safety of lifting. For a long time, the techniques for replacing the hoisting head rope mainly include board card rope changing method, steady car rope changing method, chain hoist rope changing method, etc. This type of rope changing process has a low degree of automation, high labor intensity, long time consumption, and low safety factor. Most operations are based on personnel experience, without safety guarantees, and there are many disadvantages. [0003] Recently, as the requirements for safety and efficiency of rope changin...
