(7) Rope groove back. Four-storey tower in the well child with a long board to the north side of the hook 4 new and 4 old rope firmly. 12.5mm wire with cap and traffic will be the new and old rope hanging to the old and new wire rope led from the round, starting from the east, followed by the old rope from the leading wheels, tank-oriented round of rope out, and Add new rope groove in turn, led on the old rope round or rounds of pad-oriented on the (eastern side of the rope groove). Wells to remove board tower with four sub. (8) Recovery of the old rope. At the same time, North hook hanging loose cage of two20t hoist will be closed until the new cage force of wire rope, lifting appliances, dismantled, and the old four corresponding bundled with the new wire rope. Removal of underground organizations in Southern constructors cage hook lifting equipment and work platforms. Starting distance from the winch, and a I-beam removal of. After checking no problem to begin with low-frequency North hook cage decentralization, with the old rope through human well-oriented round of the four 1:3 corresponding rope drag on the roller, at the same time, new and old ropes and Negro In addition. When the South Hook 1:3 wells can reach the top of the appropriate parking location, using gas cutting steel wire rope in the old cut-off above the first hook, and drag the working area without prejudice. Well 1:3 in the appropriate location. North side of the tank 4 old rope cut by gas cutting, and then to the north side of the tank 4 with 6 the corresponding old new rope tied solid and well-head side of the South can take temporary work platform. Starting winch, hook cage south decentralization, while the remaining out of the old rope, after the removal of temporary work platform. (9) Transfer to justice, after all, no problem, winch test run, commissioning a variety of protection. 3、 Construction Notes (1) Signal is the key to the construction, we must set up the command center, put to justice and enhancing the signal to separate the signals, at least to prepare two sets of signals, and winch drivers, put ropes and other staff to participate in the construction clearly. (2) The length of board and hand chain hoist, and early tests, such as appliances, and construction must be firmly card. (3) In the interception of a new rope should be based on precise calculation of the amount in advance from a good length of rope, new rope can not be truncated, otherwise, would be lost by the wayside, causing a greater loss. (4) Use of this method with the traditional solid car with rope method, the construction time is short. Cao coal for the use of this method were used rope 19.5h, save time 1/3 polyunsaturated. 4、 Conclusion (1) Of this method with the traditional solid car with rope method, the 7 construction time is short, Cao coal for the use of this method were used rope 19.5h, save time 1/3 polyunsaturated.
