Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device for elevator machine room equipment for lifting equipment installed in an elevator machine room.

[0002]

2. Description of the Related Art A conventional lifting device for elevator machine indoor equipment is disclosed in Japanese Patent Application Laid-Open No. 7-157233.
A trolley beam for guiding a trolley equipped with a lifting machine, and a supporting structure having a pair of parallel beams supporting both ends of the trolley beam and supporting columns provided at both ends thereof. Props were installed on the floor of the machine room.

[0003]

As described above, the conventional lifting device for elevator machine room equipment has a support structure disposed on the floor of the machine room and applies a load of a heavy object such as a hoist to the machine room. Although the floor of this machine room was made of concrete and had a lifting opening, it did not have such a high strength because it had a lifting opening. Since a heavy object such as a hoist cannot be lifted, it is necessary to reinforce the floor of the machine room or disassemble the hoist and lift the unit in appropriate units.

[0004] It is an object of the present invention to provide a lifting device for elevator machine room equipment capable of lifting heavy objects without reinforcing the floor of the machine room. .

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a trolley beam for guiding a trolley provided with a hoist and a support structure for supporting the trolley beam. In the lifting device of the elevator machine indoor equipment so as to lift the equipment to be installed by the lifting machine,
The support structure is mounted on a machine beam that supports a hoist, which is a device installed in the elevator machine room.

[0006] As described above, the lifting device for elevator machine room equipment according to the present invention supports a support structure using a machine beam provided to support a hoist in a machine room, and lifts the supporting structure using the hoist. Since the load of heavy objects is received by the machine beam, it is lifted using a machine beam with sufficient mechanical strength for its intended purpose without depending on the machine room floor which is not so strong in terms of strength. Thus, it is possible to lift the machine room floor without reinforcing the machine room floor and disassembling heavy objects as in the related art.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a lifting device of an elevator machine indoor device according to an embodiment of the present invention.
A trolley 3 on which a chain block 5 serving as a hoist is suspended is movably arranged along the trolley beam 2, and the trolley beam 2 is supported by a support structure. This support structure is composed of a frame 1 and a support 4, and the frame 1 is parallel to the trolley beam 2 and parallel beams 1 a and 1 b made of a pair of H steels arranged to be orthogonal to the trolley beam 2. The two ends of the trolley beam 2 are detachably connected to the parallel beams 1a and 1b. A large number of holes 15 are formed in the pair of parallel beams 1a, 1b at predetermined intervals in the longitudinal direction, and the holes 15 are used at arbitrary positions in the axial direction of the parallel beams 1a, 1b. The trolley beam 2 mounted above can be connected. The pair of parallel beams 1a and 1b are connected to each other by bolts via angles 1c and 1d arranged in parallel with the trolley beam 2. Four pillars 4 made of H steel are respectively established at the four corners of the frame 1, and the frame 1 and the pillar 4 are connected by bolts. In such a supporting structure, the four columns 4 are placed on a machine beam 8 to which a hoist (not shown) is attached, and the columns 4 are fixed to the machine beam 8 by rail clips 7. In addition, the hoist has four columns 4,
It is located in a space surrounded by the parallel beams 1a and 1b and the angles 1c and 1d.

The machine beam 8 has a pair of two spacers 13 stacked on each other with a seismic rubber 14 interposed therebetween on a receiving beam of a building. No. H steel is bridged. Therefore, the machine beam 8 is firmly supported with sufficient mechanical strength, and is used as a strength member for mounting and supporting a heavy hoist when the elevator is installed.

The support structure is constructed by providing the support 4 on the quadrangular frame 1 to which the trolley beam 2 is attached as described above, and the support 4 of the support structure is placed on the machine beam 8 and supported. Therefore, when a heavy hoist is suspended using the chain block 5 as a hoist, the load is received by the machine beam 8 which has sufficient mechanical strength and is strongly supported. Therefore, it is lifted using a lifting device without applying a load to the machine room floor which is not so strong in strength as in the past, and without reinforcing the machine room floor or disassembling the hoist. Will be able to do it.

As described above, the supporting structure is mounted on the machine beam 8 to carry out the lifting operation. Therefore, the position of the chain block 5 is not always at the optimum position for the lifting operation. Therefore, a pair of parallel beams 1
a, 1b are provided with a large number of holes 1 at predetermined intervals in the longitudinal direction.
5, the trolley beam 2 can be connected at an arbitrary position in the axial direction of the parallel beams 1a, 1b using the holes 15, and the position of the chain block 5 can be easily adjusted according to the lifting operation. It can be set arbitrarily. After lifting the hoist and other heavy objects using the chain block 5 of the support structure, the support structure is removed, the hoist is placed on the machine beam 8, and the machine beam 8 is moved. Used exclusively for hoisting machine support.

FIG. 2 is a plan view of a lifting device of an elevator machine indoor equipment according to another embodiment of the present invention. FIG.
The same reference numerals are given to the same components as those of the embodiment shown in FIG.
Anchor bolts 12 are respectively installed on the machine room walls corresponding to the four corners of the quadrangular frame 1 shown in FIG. 1, and between the installed anchor bolts 12 and the four corners of the frame 1 by means of a fall prevention means. A certain wire 10 and a turnbuckle 11 are stretched.

As shown in FIG. 1, a support structure having a support 4 and a frame 1 is placed thereon using a machine beam 8 and utilizing holes 15 formed in parallel beams 1a and 1b. Since the trolley beam 2 can be connected at an arbitrary position in the axial direction, the frame 1 may be unstable.
However, since the fall prevention means is stretched between each of the anchor bolts 12 cast on the machine room wall and the four corners of the frame 1, the fall of the support structure can be prevented, and the work can be performed more safely. Will be able to
