Embodiment Construction

[0025] In the operation of replacing the vertical shaft hoisting rope, the new wire rope will be slack or accumulated after being lowered for a certain distance, so it needs to be tensioned, and then a pair of steel plate clips are installed to fasten the new hoisting rope and the old rope clip stay. There are many ways to tension the wire rope, such as installing a pair of rope clips on the new hoisting rope and lifting it up with a hand hoist, or using a rope tensioner to keep the new hoisting rope in a clamped state during the lowering process. The former cycle removes and installs the board and loosens the chain hoist, which takes a long time to operate; the latter cannot effectively tighten the hoisting rope, and after the rope tightener is used for a period of time, the new hoisting rope will be too loose, or the new hoisting rope will be too loose. After the rope is accumulated, the problem that the residual rope cannot be effectively retracted. As a result, the existi...

Abstract

The invention belongs to the technical field of mine construction, and particularly relates to a construction method and system for tensioning a vertical shaft hoisting rope. The embodiment of the invention discloses a construction method for tensioning a vertical shaft hoisting rope. The construction method comprises the following steps that a clamping mechanism is manufactured according to a mining rope clamping device; a new lifting rope is clamped through a mining rope clamping device; the mining rope clamping device is clamped in the clamping mechanism; the clamping mechanism is connected with the hydraulic oil cylinder; the clamping mechanism is lifted, the mining rope clamping device body is lifted, and the lifting rope is driven to ascend, so that the lifting rope is tensioned, the problem that the speed of tensioning a new lifting rope through a lifting system oil cylinder is low is solved, it is effectively guaranteed that rope replacement operation is safely and efficiently completed, meanwhile, the clamping mechanism is wide in application range, one clamping mechanism can be used for various types of mining rope clamping devices, and the clamping mechanism is suitable for various types of mining rope clamping devices. The use flexibility is high.

Description

technical field [0001] The invention belongs to the technical field of mine construction, and particularly relates to a construction method and system for tensioning a shaft hoisting rope. Background technique [0002] There are many types of vertical shaft hoisting rope clamp devices in mining enterprises, such as pin-type rope clamps, bolt-type rope clamps, and snap-type rope clamps. to jam the hoisting rope. However, in the process of replacing the shaft hoisting rope, the hoisting rope needs to be tensioned every 25 meters or so when the new hoisting rope is lowered. If the new hoisting rope is not tensioned, the length of the new hoisting rope after replacement will be too large, so that the old rope head cannot be cut off in the later stage, and the adjustment amount of the new hoisting rope will be increased, and even the remaining rope at the upper end of the wedge ring will cause the loop. It is damaged after being stressed. Therefore, the use of a special rope c...
