Replacement process for lifting steel wire rope of vertical shaft multi-rope friction lifter

Abstract

The invention discloses a replacement process for a lifting steel wire rope of a vertical shaft multi-rope friction lifter. The replacement process comprises the following steps: (1) placing a new rope plate and an old rope receiving plate at proper positions at the balance hammer side of an upper shaft mouth, and stopping a tank cage at the position of the upper shaft mouth; (2) at the upper shaft mouth, connecting a traction rope with new and old ropes by the rope head of the new rope via a guide wheel at the balance hammer side; (3) starting a lifter to descend the tank cage by a hoist at the speed of 0.4m/s; (4) respectively clamping the new rope at a hoist house, an upper hoisting sheave and a lower hoisting sheave by compound board cards and then lifting the new rope, and dismounting the traction rope for connecting the new rope with the old rope; (5) reversely driving the hoist at the speed of 0.4m/s, and lifting the tank cage to the upper shaft mouth; (6) arranging an anti-running device and a rope tightener, and descending the tank cage until the balance hammer is lifted to the upper shaft mouth; (7) dismounting the anti-running device and the rope tightener, and mounting a rope clamper; (8) cutting off the old steel wire rope below a hoist roller, and replacing the old rope with the new rope; and (9) after the tank cage is lifted to the upper shaft mouth, mounting the rope clamper, connecting the new rope with a wedge-shaped rope, regulating the rope length, dismounting the rope clamper, and implementing pilot run after the rope replacing process is completed.

Description

technical field [0001] The invention relates to a rope replacement process for a hoisting wire rope, in particular to a hoisting wire rope replacement process for a vertical shaft multi-rope friction hoist. Background technique [0002] The existing shaft multi-rope friction hoist replacement process for the first rope replacement has the following shortcomings: 1. The existing replacement process adopts the technology of using the rope clamp and the iron plate in combination, which is complicated to operate, and the iron plate is heavy and easy to damage the rope. . 2. The existing replacement process needs to be constructed at the upper and lower wellheads, the process is relatively complex, the construction safety is poor, the work efficiency is low, a lot of manpower and material resources are used, the construction period is long and the cost is high. 3. In the existing process, the new rope is attached to the old rope and brought from the upper wellhead to the lower w...
