Description

[Detailed Description of the Invention] This invention relates to a scaffolding device required for maintenance and inspection at a high place, such as a vertical rotating electrical machine.

DESCRIPTION OF THE RELATED ART Conventionally known scaffolding devices of this type, which are used in vertical rotating electric machines, are shown in FIGS. 1 and 2.

In Figures 1 and 2, 1 is the frame of the rotating electric machine, 2
is the upper bearing part of the rotating electric machine, 3 is the footboard, 4 is the handrail,
5 is a ladder, and 6 is a support arm that is fixed to the frame 1 and supports the footboard 3.

In the conventional scaffolding device configured in this manner, the footboard 3 is supported by support arms 6, and the support arms 6 are arranged at several locations around the frame 1.

For example, when maintaining or inspecting the bearing portion 2, an inspection personnel climbs onto the footboard 3 from the ladder 5.

Since conventional scaffolding devices are constructed as described above, it takes time to manufacture, assemble, and install, and large devices have the drawback of having to be disassembled and transported due to transportation restrictions.

This idea was made with the aim of eliminating the above-mentioned drawbacks. By reducing the parts related to the scaffolding device, manufacturing, assembly and installation are easier, and it can be mounted compactly and tightly attached to the frame during transportation. The present invention provides a scaffolding device that makes it possible to

An embodiment of this invention will be described below with reference to FIGS. 3 to 7.

In FIGS. 3 to 7, 7 is a mounting part for equipment such as the frame 1 of a rotating electric machine, and 8 is a support arm that is attached to the mounting part 7 with a fastener 9 and can be extended outward. There, it is holding the footboard 3.

10 is a stop plate provided at the bottom of the foot plate 3.

Note that reference numerals 1, 2, and 4.5 have the same configurations as those shown in FIGS. 1 and 2, and therefore a description thereof will be omitted.

In the scaffold of this invention constructed in this manner, the footboard 3 and handrail 4 fixed to the support arm 8 can be easily assembled or disassembled at the same time by tightening or removing the fasteners 9.

Also, when transporting or transporting equipment equipped with scaffolding equipment, the ladder 5 should be removed and the footboard 35 handrail 4 should be replaced with the supporting arm 8.
6 and 7 by removing the fastener 9, swapping the support arms 8 left and right, bringing the footboard 3 into contact with the device 7, and holding the device 7 between the handrails 4. As shown, it can be compactly stored close to the frame 1.

Although the above example shows an example of a vertical rotating electric machine, it can of course be applied to various types of equipment that require maintenance and inspection at high places, and hinges are used instead of bolts. There is also a foldable method.

As described above, this invention has excellent practical effects by shortening the manufacturing period of the device and reducing transport and shipping costs.

Claims (1)

[Scope of utility model registration request] A device that has a mounting part installed near the inspection point at a high place, facing the device through this device, and detachably attached to the above-mentioned mounting part, facing outward from the above-mentioned device, in a direction approximately perpendicular to this device. A support arm that can be extended to the outside, a footboard that is suspended and fixed between the support arms and on which inspection personnel can be placed, a handrail installed at both ends of the footboard, and a handrail that allows the support arm to be extended outwardly. A ladder that can be suspended from the footboard when extended toward the side is provided, the support arm is removed from the mounting part with the footboard 5 handrail provided on the support arm, and the positions of the face support arms are swapped left and right. A scaffolding device characterized in that a handrail is brought into contact with the equipment and the equipment is held between the handrails.
