Description
Technical Field
The present invention relates to an elevator hoist and a method for installing an elevator hoist.
Background
Conventionally, a hoist for an elevator is installed in an elevator apparatus by fixing a structure (a guide rail, a wall surface of a hoistway, etc.) between the hoist and the elevator apparatus by bolts or welding. In the case of installing a hoist in a building where use of a firearm is prohibited, it is necessary to use bolt-based fastening because welding work cannot be performed. For bolt-based fastening, for example, patent document 1 describes fastening a hoist to a machine table attached to a guide rail by a stud bolt.
Prior art literature
Patent literature
Patent document 1: international publication No. 2016/030943
In the case of fixing by bolts as in patent document 1 described above, members (machine beams, spacers, and the like) for fixing the hoisting machine and the hoistway are usually perforated on site and fixed by bolts. However, the tapping operation in the field requires much time and expense. On the other hand, when these members are perforated in advance, there is a problem that dimensional errors of the building cannot be completely handled at the time of on-site assembly.
In addition, in a fixing method other than welding or bolts (for example, an adhesive agent), fixing is insufficient, and if a fixing portion slips due to an earthquake or the like, there is a risk that the hoist itself falls over.

Detailed Description
Hereinafter, the elevator hoist and the method for installing the elevator hoist according to the present invention will be described in detail with reference to the drawings.
Fig. 1 is a schematic diagram showing an example of an elevator apparatus provided with an elevator hoist (hereinafter, simply referred to as "hoist") according to the present invention. As shown in fig. 1, the elevator apparatus 200 includes a car 4 provided in a hoistway 7, a counterweight 5, and an elevator rope 6 connecting the car 4 and the counterweight 5. The elevator rope 6 is driven by a hoist 100 provided at the upper part of the hoistway 7, and the car 4 and the counterweight 5 are lifted and lowered by driving the rope 6.
The hoisting machine 100 includes a machine body 1, a machine beam 2 supporting the machine body 1, and a spacer 3 connecting (fixing) the machine beam 2 to a structure of the elevator apparatus 200. In fig. 1, the spacer 3 is connected to the top surface of the hoistway 7, but the place where the spacer 3 is connected is not limited to this, and may be, for example, a wall surface of the hoistway 7 or a guide rail (not shown) for guiding the direction of lifting of the car.
Next, the structure of the hoist 100 of fig. 1 will be described in detail. Fig. 2 is a view showing a first example of the hoist of the present invention. The hoist 100a shown in fig. 2 includes a machine body 1 around which an elevator rope is wound, a pair of machine beams 2a and 2b that support the machine body 1, and a pair of spacers 3a and 3b that extend in a direction perpendicular to the machine beams 2a and 2b at both ends in the longitudinal direction of the pair of machine beams 2a and 2 b. As shown in fig. 2, bolt holes are provided in the machine body 1 and the machine beams 2a and 2b, respectively, and bolts are inserted through the bolt holes, whereby the machine body 1 and the machine beams 2a and 2b can be fixed.
Fig. 3 is a view showing a second example of the hoist of the present invention. In the hoist 100b shown in fig. 3, a pair of spacers extending in a direction perpendicular to the machine beams 2a,2b at both ends in the longitudinal direction of the pair of machine beams 2a,2b is further divided into two parts up and down, so that the hoist 100b has four spacers 3a,3b,3c,3d in total. Vibration-proof rubber 8 is provided between the spacers 3a and 3c and the spacers 3b and 3d. By adopting such a structure, the vibration applied to the hoist 100 can be absorbed, and the hoist can be stabilized. The present invention is not particularly limited as long as it includes the above-described machine beam and spacer.
Fig. 4 is a diagram showing a first fixation scheme of the machine beam and the spacer. Fig. 5 is a diagram showing a detailed structure of the end portion a of fig. 4, and fig. 6 is a diagram when fig. 5 is viewed from the direction C. Fig. 7 is a diagram showing a detailed structure of the end B of fig. 4.
As shown in fig. 4, a rail clip 9 is provided at one end in the longitudinal direction of the machine beams 2a,2b, and a bolt hole 11 into which a bolt is inserted is provided at the other end. Further, a rail clip engagement long hole 10 into which the rail clip 9 is inserted is provided at one end portion of the spacer 3a where the rail clip 9 is provided in the machine beams 2a,2 b. Further, bolt holes 12 are provided at one end of the spacer 3b where the bolt holes 11 are provided in the machine beams 2a,2 b.
As shown in fig. 4 and 7, bolts 15 are inserted into the bolt holes 11 of the machine beam 2a and the bolt holes 12 of the spacers 3b via washers 16, and the lower portions of the bolts 15 are fastened by nuts (not shown), whereby one ends of the machine beam 2a and the spacers 3b are firmly fixed (shear-fixed) by the bolts.
On the other hand, as shown in fig. 4 to 6, in a state in which the rail clips 9 of the machine beams 2a,2b are inserted into the rail clip engagement long holes 10 of the spacers 3a, the rail clips 9 are movable along the rail clip engagement long holes 10, so that the positions of the other ends of the machine beams 2a,2b and the spacers 3a, which are fixed by the bolts 15, can be adjusted while moving the rail clips 9, with the one ends of the machine beams 2a,2b and the spacers 3a fixed as fulcrums. After the adjustment is completed, as shown in fig. 6, the bolts 13 are passed through bolt holes (not shown) provided in the rail clips, and the lower portions of the bolts 13 are fastened by nuts 14, whereby the other ends of the machine beams 2a and 2b and the spacers 3a are fixed.
As described above, with the hoist of the present invention, one ends of the machine beams 2a,2b and the spacers 3a,3b are firmly fixed beforehand by bolts. In this state, the other ends of the machine beams 2a,2b and the spacers 3a,3b are temporarily fixed in a state where adjustment movement for positioning is possible, and are firmly fixed by bolts after adjustment. With such a structure, the working time can be shortened without requiring a site hole-forming operation, and the dimensional errors of the building can be flexibly dealt with. Further, since the final fixing is performed by the bolts, it is possible to provide a hoist for an elevator with high safety, which can reliably fix the hoist.
The portions where the machine beams 2a and 2b and one end of the spacer 3b are fixed by bolts may be other shearing fixing methods as long as they are firmly fixed.
The other ends of the machine beams 2a,2b and the spacer 3a are fixed by the rail clips 9, but an adhesive may be used, for example, as long as the other ends of the machine beams 2a,2b and the spacer 3a can be moved by a temporary fixing method.
Fig. 8 is a diagram showing a second fixation scheme of the machine beam and the spacer. As shown in fig. 8, the rail-engaging long holes 10 provided in the spacer 3a are not limited to one, and a plurality of long holes may be provided along the longitudinal direction of the spacer 3 a. Further, one long hole provided along the longitudinal direction of the spacer 3a may be provided with a plurality of rows in the width direction, or a plurality of long holes provided along the longitudinal direction of the spacer 3a may be provided with a plurality of rows in the width direction. The number and shape of the long holes 10 for rail clamping are not particularly limited as long as the positions of the machine beams 2a,2b and the spacers 3a can be adjusted.
As described above, it has been confirmed that the present invention can provide a high-safety elevator hoist and a method for installing an elevator hoist that can flexibly cope with dimensional errors and reliably fix the hoist.
The present invention is not limited to the above-described embodiments, and includes various modifications. The above-described embodiments are for the purpose of easily understanding the present invention, and are not limited to the embodiments having all the configurations described. In addition, a part of the structure of one embodiment may be replaced with the structure of another embodiment, and the structure of another embodiment may be added to the structure of one embodiment. In addition, other structures may be added, deleted, or replaced to a part of the structures of the embodiments.
