[0002] The existing floor-type friction hoist tail rope replacement method is to lift the head and tail of the old tail rope to the position corresponding to the wellhead and the bottom of the well, and then first lower the new rope at the wellhead through guide chains, car stabilizers and other equipment, and put the tail rope This method of replacement has the following disadvantages: 1. The new rope is relatively long and hangs from the wellhead to the bottom of the wellbore in the wellbore. During the rope change process, it is easy to scrape the equipment in the wellbore, and the risk factor is high; 2. The old rope The whole tail rope is cut off, which is heavy and difficult to recycle; 3. During the replacement process, more large-scale equipment needs to be used for lifting and lowering, the operation is cumbersome, and the maintenance process such as lowering the new rope and recycling the old rope takes a long time , low maintenance work efficiency

Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Such as figure 1 As shown, this embodiment is a method for replacing the tail rope of a floor-type friction hoist, including the following steps:
[0030] 1. Preparation work:
[0031] S1. Fix a rope buckle on the channel steel about 50 centimeters below the cage side rail at the -720m wellhead, install a redirection pulley 2 through the rope buckle, and then install a 3t winch 1 at the -720m wellhead for standby. In the same way, a reversing pulley 2 is installed on the channel steel at the -744m loading station on the skip side through a rope buckle, and a 1t winch 3 is installed at the -744m loading station for standby.
[0032] S2. Place the new tail rope that needs to be replaced at the -720 wellhead through the tail rope frame car 6 in advance, fix the tail rope frame car 6, and make a new rope head in advance and assemble the rotator. ...

The invention relates to tail rope replacing method of a floor type friction elevator. The tail rope replacing method comprises the steps of preparation work, segmented recovery of an old tail rope, lowering of a new tail rope and the like. According to the tail rope replacing method of the floor type friction elevator, the lowering of the new tail rope and the recovery of the old tail rope are carried out at a-720 wellhead and a-744 loading station, the lowering distance is short and the weight is light in the lowering process of the new rope, facilities such as a cage guide in a shaft cannotbe scratched, the new rope can be put down only through cooperation of a pulley and a winch, the operation is easy, equipment between-720 in the shaft and the bottom of the shaft is few, the danger coefficient is low, segmented cutting and detaching are carried out in the detaching process of an old tail rope, recycling is convenient, the overhauling time is greatly shortened, potential safety hazards are reduced, and the working efficiency is improved.
