Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a lifting jig for removing an electric motor from an elevator drive having an electric motor and a hoist. 2. Description of the Related Art Elevator driving devices require component replacement due to deterioration of components due to aging. At this time, the motor is often removed and the bearings and oil seals are replaced. When removing the motor,
Conventionally, a method has been adopted in which a tripod is set up near the installation position of a drive device, a chain block is attached to the tripod, and a motor is hung. However, since the tripod used at this time is large and heavy, a large storage space is required, and it takes time to transport the tripod to the site. In addition, depending on the situation at the site, it is not always possible to stand safely, and if there is not enough space near the drive device, the tripod may not be able to stand. [0004] The present invention has a construction in which a jig for holding a motor is attached to a hoist. Thereby, the hanging jig can be reduced in size, and the hanging jig can be safely installed regardless of the installation position of the driving device. An embodiment of the present invention will be described with reference to FIGS. 1 and 2. In the figure, reference numeral 1 denotes a driving device including a hoisting machine 2 and an electric motor 3. Reference numeral 10 denotes a hanging jig, and 1
Reference numeral 1 denotes a main body having an L-shaped cross-section support bracket 12 at the center and an L-shaped cross member 13 at an end portion. Reference numeral 14 denotes a support plate fixed to the tip of the support bracket 12. Reference numeral 15 denotes a fixing bracket having an L-shaped cross section, and a plurality of holes for fixing the fixing bracket to the hoist 2 are formed in a lower portion. Reference numeral 16 denotes a reinforcing plate. When using the hanging jig 10, the main body 11, the fixing bracket 15, the plate 16, and the chain block 30 as a lifting tool are carried in, and the cross member 13 is set on site.
The fixing bracket 15 is fixed to the horizontal member 11, and the plate 16 is further fixed to the cross member 11 and the fixing bracket 15. Then, the support plate 14 is placed near the electric motor 3 of the hoisting machine 2, for example, on a brake cover. Next, the bearing cover 2a of the hoisting machine 2
Then, a part of the bolts is removed, and the fixing bracket 15 is tightened and fixed to the hoisting machine 2 through the hole at the lower part of the fixing bracket 15. Further, a chain block 30 is attached to the other end of the main body 11, the hook of the chain block 30 is hooked on the electric motor 3 to support the electric motor 3, and the electric motor 3 is removed from the hoisting machine 2 to replace parts. I do. As described above, since the hanging jig 10 of the present embodiment is attached to the driving device 1, it is smaller and lighter than a conventional tripod, and is disassembled and assembled on site, so that it can be easily transported and stored. is there. In addition, unlike the conventional configuration in which a tripod stands near the driving device 1, the device can be safely installed even if there is not enough space near the driving device 1. In the above-described embodiment, holes at the lower portion of the fixing bracket 15 are opened so as to correspond to a plurality of types of hoists, and the fixing of the support bracket 12 to the main body 11 is performed by tightening bolts or the like. If the fixing position to the main body 11 is adjustable and the mounting position of the chain block 30 to the main body 11 is also adjustable, one suspension jig 10 can be applied to a plurality of types of driving devices. In the above embodiment, the fixing bracket 15
Is fixed to the bearing cover 2 a, but is not limited to this, as long as one end of the main body 10 can be fixed to the hoisting machine 2. The chain block 30 may be another lifting device as long as the motor 3 can be hung. As described above, according to the present invention,
The motor can be hung by a small lifting jig, and the removal operation of the motor can be performed safely and easily.
