DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to elevator car hangings.

[0002]

2. Description of the Related Art As shown in FIG. 5, a wire with a base 33 is wound around a machine base 32 for mounting and supporting a hoisting machine (not shown) installed in a machine room 31 as shown in FIG. Also, on the side of the car 34, the wire with the platform 35 is passed under the cross head (upper beam) 36, and the wires 33 and 35 with the platform are connected by the giant 37 to suspend the car 34. I was

[0003]

In the above-mentioned prior art, since the base wire 35 is wound around the crosshead 36, when the car 34 is suspended, the car 34
Depending on the weight of both horizontal portions 36a of the crosshead 36,
36b exerts a pushing force in a direction to approach each other,
The crosshead 36 may be deformed.

An object of the present invention is to provide an elevator car suspension capable of suspending a car without applying a horizontal force that causes deformation of the crosshead.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hoistway formed over a plurality of floors of a building, a machine room formed at the top of the hoistway, and a hoist installed in the machine room. An elevator car hanger having a car vertically moved via a main rope hung on a sheave of a hoist, a beam material longer than the width of the crosshead of the car, And a suspension fitting coupled to project from both ends of the beam material, a suspension fitting coupled to be positioned at an equal distance from the end of the beam material, and a suspension fitting coupled to be positioned at an equal distance from the end of the beam material. This is achieved by the slip stopper being coupled to the crosshead when in use, and the suspension fitting being disposed outside the crosshead during use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3 and 4. FIG. In FIG. 1, reference numeral 1 denotes a machine room formed at the uppermost part of a hoistway, 2 denotes a pair of machine beams fixed to the floor of the machine room 1, and 3 denotes a hoist which is fixed on the machine beam 2 (not shown). 3) A machine base for mounting and fixing, 4 is a rectangular main rope opening formed on the floor of the machine room 1, 5 is a duct attached to the periphery of the opening 4, 6 is a car, and 7 is a car. A crosshead (upper beam) of the car 6, which supports the car 6 by two vertical frames and a lower frame connected thereto. A main rope (not shown) is attached to the crosshead. 8 is the machine room side car hanging tool, 9 is the car side hanging tool, 10 is the shrimp, 1
Reference numeral 1 (11A to 11C) indicates a rope with a base. The machine-room-side car hanging device 8 includes a beam member 8A having an H-shaped cross section and longer than the maximum dimension of the opening 5 and a hanging member 8B protruding and fixed at an intermediate position in the longitudinal direction of the beam member 8A. It is configured. The car-side suspension 9 is composed of a beam 9A having a U-shaped cross section, a pair of suspensions 9B attached near the end of the beam 9A, and a pair of stoppers 9C. Is mounted at a position where the distances from both ends are equal, the stopper metal 9C engages inside the crosshead, and is mounted at a position where both distances from the ends are equal.

For example, a car 6 for replacing a main rope, etc.
In the case of hanging, the rope 11A with the base is connected to the machine room side car hanging tool 8 by the shank 10, the rope with the base 11A is hung from the opening 4, and the beam material 8A is lowered with the hanging metal fitting 8B down to the machine beam 2. Place on top.

On the other hand, the car side suspending tool 9 is inserted under the cross head 7, and the ropes 11B and 11C with the platform are attached to the suspending metal 9B by means of the manicurer 10, and the rope 11 with the platform is attached.
A, 11B, and 11C are joined by a giant clam 10. In this state, the stopper metal 9C is engaged with the inside of the crosshead 7.

[0009] Next, the car 6 is lowered little by little, or the pedestal rope 11A and the other pedestal ropes 11B, 1B,
The car-side suspending tool 9 is raised by the chain block with the chain block interposed between the car 1 and the car 1 and the car 6 is suspended. As a result, the main rope (not shown) is loosened, so that a predetermined operation such as replacement of the main rope or other operation to be performed with the rope loosened is performed.

As described above, the machine room side suspending member 8 is composed of the beam member 8A and the suspending member 8B protruding from the beam member 8A.
There is no need to perform winding around the machine base 3 and the rope with base 11A can be positioned in the center of the opening 4, that is, on an extension of the center of gravity of the car 6, and the car 6 can be hung in a stable state. Can be kept. Further, it is possible to prevent the base-attached rope 11A from contacting or rubbing the corner of the peripheral edge of the opening 4. Further, since the base rope 11A does not contact the corner of the periphery of the opening 4, the duct 5 attached to the periphery of the opening 4 also has
Since there is no contact, deformation and breakage of the duct 5 can be prevented.

[0011] Further, as the car side suspending tool 9, a beam material 9 is provided.
A, since the one having the hanging fitting 9B is used, the car 6 can be hung without applying any deforming force to the crosshead.

FIG. 3 shows another embodiment of the present invention, in which a slip stopper 9C is engaged with the crosshead 7 outside the crosshead 7. As shown in FIG.

FIG. 4 shows a still further embodiment of the present invention, in which the function of a stopper metal 9C is given to a hanging metal 9B.
The hanging metal fitting 9B is attached at a position where the hanging metal fitting 9B engages with the hook. According to this embodiment, the stopper metal 9C can be omitted, and the length of the beam member 9A can be shortened.

[0014]

As described above, according to the present invention, it is possible to suspend a car without applying a horizontal force that causes deformation of the crosshead.
