  At the time of installing the elevator or exchanging the main rope, for example, the rope is pulled out from a drum installed on the top landing floor and including the rope, and the rope is hung in the hoistway.

  In the rope hanging work, a rope brake is disposed in the vicinity of the sheave to prevent the rope from drooping at an excessive speed when the rope wound around the driving sheave is suspended in the hoistway.

  Usually, a plurality of ropes are often used for hanging a car in a rope type elevator. In that case, a plurality of ropes are hung by repeating the rope hooking of one rope drawn out from the drum around which the rope is wound a plurality of times.

  As described above, in conventional elevator rope hanging, the ropes are taken out one by one from the drum and wound around a driving sheave or the like.

Therefore, when suspending the basket arranged in parallel a plurality of ropes, pulled out from the rope drum, and the winding operation to the traction sheave or the like must be repeated several times, the more new installation and rope replacement Since much time was required for the work , improvement was desired.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator rope hanger suitable for pulling out a plurality of ropes from a drum at the same time and performing the plurality of drawn ropes simultaneously.

The elevator rope hanging device according to the present invention includes a pair of comb-like members arranged in parallel with a plurality of slits into which ropes can be inserted inward from edges facing each other, and the pair of comb-like members. And a connecting means that can be connected in an overlapping state of the slits arranged side by side, and one of the pair of comb-shaped members is configured such that the length of the slits is sequentially shortened in the arrangement direction. It is structured .

According to the elevator rope hanging apparatus of the present invention, since the plurality of ropes have comb-like members that can be locked one by one, when the worker performs the rope hanging work simultaneously on the plurality of ropes, The ropes can be locked in a state of being arranged in order. Therefore, entanglement of a plurality of ropes is prevented, and the rope hanging operation can be performed efficiently. In addition, since either one of the pair of comb-shaped members is configured such that the length of the slit is sequentially shortened in the arrangement direction, the pair of comb-shaped members are crossed in a fan shape, and the opening angle is adjusted. Thus, the rope can be fitted between the slits one by one, or the rope can be removed from the slits in a good manner .

  Further, the rope can be individually locked to the rope receiving member attached to the guide rail via the rope pressing member. Therefore, when a worker connects a plurality of ropes to the rope hitch installed on the guide rail, the rope can be hooked by detaching one by one in sequence, as well as improving work efficiency.

  The handle 13 of this embodiment is composed of a slightly rigid rope, and is connected to two plate members 11a and 11b to which a plurality of ropes 2 whose ends are arranged in parallel are fixed. As described above, since the plurality of ropes 2 can be wound around the sheaves 3 and 3 at a time by wrapping around the sheaves 3 and 3 with the handle 13 at the top, the winding work by the worker is efficient. Can be implemented.

  As shown in FIG. 2, when the ropes 2 are wound around the sheaves 3, 3 by routing the handle 13, the handle 13 supports the rotation shafts of the sheaves 3, 3 at both ends. Since it is necessary to pass between the fixtures 3a, 3a, the width d of the handle 13 is preferably shorter than the distance D between the fixtures 3a, 3a.

  FIG. 3 is a perspective view showing a second embodiment of an elevator rope hanging apparatus according to the present invention.
