Description

[Detailed explanation of the invention] This invention relates to a fall prevention device for boxes such as electrical equipment panels, which is suspended from above inside the building so that tests in the factory and installation on site can be performed. .

Some electrical equipment panels, such as communication equipment panels, have a small ratio of depth to height and may fall over.

When such a box is tested at a factory or installed on site, it must be temporarily supported to prevent it from tipping over.

A conventional fall prevention device for this type of box was as follows.

A metal duct for wiring was suspended from the ceiling with hanging bolts, and a hanging metal fitting made of band-like plate material was attached to it, and the box was connected to the bottom of this metal fitting with bolts to support it.

In the conventional device described above, the suspension is supported by hanging metal fittings and connecting bolts, and several different lengths of hanging metal fittings are required for boxes of different heights, and tools such as spanners are required for attachment and detachment. However, it was time-consuming to install and remove.

This idea supports the support fittings on a fixed part above the building,
A lower receiver connects the bracket to the support bracket in a removable manner without the need for tools, and this receiver lowers the draw rod to the bracket, and connects the lower hook to the upper hanger of the box via the turnbuckle. To provide a device for preventing overturning of a box body, which can be hung and supported from above, can be attached and detached in a short time without requiring tools for attachment and detachment, and has improved workability.

FIG. 1 is a schematic side view of a box fall prevention device according to an embodiment of this invention.

Reference numeral 1 denotes a box for electrical equipment panels, etc., parts are assembled inside, and the box is placed on the floor 2.

3 is a plurality of hanging bolts fixed to the ceiling 4 of the building and hung; 5 is a metal duct for wiring supported by these hanging bolts; It is provided with an opening groove in the direction.

6 is a metal fitting hung on the metal duct 5; 7 is a metal fitting attached to both sides of the supporting metal fitting;
Reference numeral 8 denotes a screw rod that is hung downward from the metal fitting, 9 is a turnbuckle that connects this screw rod, and 10 is a hook that is connected to this turnbuckle at the upper male thread and hangs the box 1. .

The support fitting 6 and the support fitting 7 are shown in an enlarged front view in FIG. 2 and in a side view in FIG. 3.

The support fitting 6 has an inverted U-shape, and has inverted pothole holes 6a at the lower portions of both sides extending from the upper side.

The bracket 7 has a U-shape, and a forward-facing pothole hole 7a is provided at the top of both sides extending from the bottom, corresponding to the pothole hole 6a. Fitted in.

The receiver pushes up the metal fitting 7 so that the large-diameter holes of both of the pothole holes 5a and 7a are aligned, and the coupling bolt 11 with the nut 12 is inserted into these large-diameter holes.
When pulled down, the small diameter holes of both pothole holes 6a and 7a are aligned, and the connecting bolt 11 connects both and is prevented from being removed.

A threaded rod 8 having a nut 13 fitted at the upper end is hung from the metal fitting 7 of the receiver.

A hanging handle 14 such as an eye bolt is provided on the upper part of the box body 1, and is hung by a hook part 10a of a hooking fitting 10.

By turning a turnbuckle 9 fitted between the hook and the threaded rod 8, the box 1 is vertically suspended.

Suspension support using the device of the above embodiment is performed as follows.

A support fitting 6 is hung on the metal duct 5 at a position directly above the box body 1.

Hang the hook 10 on the handle 14 of the box body 1, turn the turnbuckle 9 by hand, and make sure that the large diameter hole of the pothole 7a of the metal fitting 7 is connected to the pothole 6a of the catch connected to the upper end of the threaded rod 8. Adjust to match larger diameter hole.

If they match, the nut 12 is fitted into the connecting bolt 11.
Insert the bracket and lower the metal fitting 7 to make both pothole holes 7a,
The small diameter holes 5a match, and the connecting bolt 11 connects both parts and is prevented from being pulled out.

Next, turn the turnbuckle 9 by hand to adjust the tension on the box 1.

In this way, the box body 1 is prevented from falling over, and a factory test is performed.

To remove the fall prevention device, follow the procedure in reverse order to the above.

In addition, in the above embodiment, as a fixed part above the building,
Although the metal duct 5 suspended and supported from the ceiling is used, an upper girder or other fixed facility may also be used.

Further, although the above embodiment is applied to a box testing process, the present invention is not limited to this, and can also be applied to on-site installation.

As described above, the supporting metal fitting is supported on the upper fixed part, the receiving metal fitting is connected to this supporting metal fitting from below, and this supporting metal fitting is connected to the draw rod lowered from the metal fitting and hooked to the hanging handle of the box body. The hooks are connected with turnbuckles to suspend and support the box, so it can be easily attached and detached without the need for tools, allowing for quick work even when working at heights. can.
