定および解除を行なっている。[Function] Since the method for replacing the main rope of an elevator according to the present invention is performed as described above, according to the first invention, after both the elevating bodies are fixed, the existing rope is fixed on the upper part of the hoisting path and one of the elevating and descending bodies is replaced. At the same time as cutting at the joint on the body side, the cut part is joined to one end of the new rope installed near this lifting body, while cutting the joint on the other lifting body side fixed at the bottom of the hoistway, Then, since the existing rope is recovered at the bottom of the hoistway, the new rope is sent in on one hand and the new rope is recovered on the other hand, so that the winding of the new rope and the recovery of the existing rope can proceed at the same time. The main rope can be replaced efficiently and quickly. In addition, the work of joining existing ropes and new ropes can be done at landings where there is little risk of falling, making the work safer. According to the second invention, after both the lifting bodies are fixed, the existing rope is fixed with a rope fixing device, and the existing rope is cut at the joint on the side of one of the lifting bodies fixed on the upper part of the lifting path. Connect the cut part to one end of the new rope installed near this elevator, cut the joint of the existing rope on the other elevator that is fixed at the bottom of the hoistway, and release the rope fixing device. ,Then, the existing rope is recovered at the bottom of the hoistway, so even if the main rope weighs more than several hundred kilograms above the hoistway in a high-lift elevator, the rope fixing device can securely secure the existing rope. This prevents the main rope from falling due to its own weight and causing an accident. [Example] An example according to the present invention will be described below with reference to the drawings. As shown in Figure 1, a hoistway extending over many floors
A car 2 and a counterweight 3 which are movable up and down along respective guide rails (not shown) are housed in the car. A sheave pulley 5 and a deflection pulley 6 driven by a hoisting machine (not shown) are installed in the first machine room 4 formed at the top of the hoistway, and a plurality of existing ropes 7 are attached to each pulley. It's wrapped around. These existing ropes 7 are fixed to the heel 2 at the upper end b of the hoistway 1, and to the counterweight 3 on the pedestal 14 at the lower end C of the hoistway 1. A brake device 11 is provided on the heel 2 side of the existing rope 7 passing through the second machine room 10 to adjust the payout speed of the new rope 9, and a rope fixing device is provided on the counterweight 3 side of the existing rope 7. ii! 12 are provided. Both devices will be explained with reference to Figs. 2 to 5. Second
3 and 3 are a plan view and a front view of the brake device 11. A pair of supporting members 18 at the bottom of the upper frame 19 support the existing rope 7 or the new rope 9, and their strength is adjusted by bolts 20 and adjustment springs 21 to provide the necessary braking force. 4 and 5 are a plan view and a front view of the rope fixing device 12. The retaining plate 22 erected on the lower frame 25 is provided with a groove, and the existing rope 7 or the new rope 9 is fixed between the groove and the groove of the pressure contact plate 23, and the bolt 24 is used to fix and release the existing rope 7 or the new rope 9. is being carried out.

新設ロープ繰り出し装置８を片付ける。By the way, a newly installed rope feeding device 8 is installed on the top floor l5, and a newly installed rope 9 is wound around it. This I8 can also be equipped with a simple brake mechanism. In addition, the existing rope winding device 117 is installed on the lowest floor 16.
is installed, and the existing rope 7 is wound around it. Figure 6 explains the joining of the existing rope 7 and the new rope 9. This joint is strong enough to hold the rope's own weight, and is connected in such a way that the rope diameter does not become extremely thick. One example is a method of using a sleeve 13 for crimping wires and crimping them with a hydraulic ram or the like. There are other methods of welding between ropes. Next, we will explain how to replace the main rope. First, the counterbalance 113 is held by its pedestal 14 at the bottom of the hoistway 1, and the car 2 is hoisted by a chain block (not shown) at the top of the lift plhJI1. When the tension of the existing rope 7 reaches the level due to the rope's own weight, fix the existing rope 7 with the rope fixing device W1l2. Next, the chain block that has lifted the car 2 is further hoisted, and when the existing rope 7 becomes loose, the existing rope 7 is completely cut near the upper end b of the heel 2 6 From the newly installed rope feeding device 8 on the top floor 15 Pull out the new rope 9 and connect it to the existing rope 7 at part a.
Next, cut the existing rope 7 at the upper end C of the counterweight 3,
Connect the cut section to the existing rope winding device l7 on the lowest floor l6. At this point, only one of the existing ropes 7 fixed to the rope fixing device 12 is released, and the new rope 9 is wound while winding the existing rope 7. At this time, the speed at which the newly installed rope 9 is fed out can be adjusted by operating the brake device 11. In this way, when the joint a of the new rope 9 and the existing rope 7 has descended to the existing rope winding device 17, the new rope payout device 8 is stopped, the joint a of both ropes is cut, and the ends b and c are cut. Join the end of the new rope 9. The remaining three are replaced in the same way, the chain block and pedestal 14 are removed, and the brake device 11, rope fixing device 1112, and newly installed rope feeding device 8 are put away.
