Description

[Detailed description of the invention] This invention mainly relates to the improvement of electrical equipment boxes such as railway signal equipment, and is aimed at simplifying and speeding up the replacement work of electrical equipment and cases.

Railway signaling devices such as relays are usually installed close to the railway tracks, but especially in the case of equipment installed along Shinkansen lines,
Vibration caused by the passing of high-speed trains and violent vibrations caused by wind pressure can cause significant damage to equipment and outer cases, which must be replaced frequently.

However, conventional signals such as relays for ball track vehicles are the first
As shown in the figure, the pedestal 7' on which the electrical equipment 15 is attached is
The top I of the stand 14 integrally attached to the bottom plate 13 of the outer case 1'
= It is fixed via vibration isolating rubber 6', etc., and the outer case 1' is fixed in place with bolts, etc., so whether it is the internal equipment or the outer case that requires replacement. First, since the device and the outer case are integrally constructed, there is the disadvantage that both must be removed at all times, and therefore, the replacement work requires a lot of effort and time.

In addition, when replacing them, it is necessary to stop various electrical functions, which has the drawback of causing a great deal of trouble in controlling trains and other electrical devices.

This invention is a method for disconnecting electrical connections or removing electrical equipment to cut off or stop the electrical system for signal protection in railway electrical equipment boxes where electrical equipment for signal protection is stored. To provide a railroad electrical equipment box in which only the outer case of the electrical equipment box can be easily attached/detached or replaced without removing the electrical equipment box.

In other words, this idea allows installation of multiple gate-shaped frames with legs that can be installed across gutters, etc. on the top surface of a stand, and for installation of equipment made of frames, the electric equipment is removably fixed via the stand. 1. The electric equipment and the equipment mounting are characterized in that an outer case consisting of a box that can cover the stand and has an open bottom is fixed to the upper surface of the stand, and the equipment mounting is detachably fixed to the upper surface of the stand separately from the stand. Common in railway electrical equipment boxes.

Hereinafter, one embodiment of this invention will be described based on FIGS. 2 and 3.

First, the outer case 1 that houses the equipment is box-shaped as a whole with an opening at the bottom 17, has an opening/closing door 2 at the front, and a reinforcing frame 3 at the bottom.
are fixed together, both ends of the reinforcing frame are exposed to the outside, and this part is installed as if it were attached to the stand 4.

In addition, for equipment inside the outer case, to install equipment large enough to fit into the reinforcing frame 3 at the bottom of the outer case, an L-shaped pedestal 7 is integrally attached to the pedestal 5 via anti-vibration rubber 6. This frame 7
The equipment is mounted by fixing the plate 8, and the equipment is installed by attaching the platform 5 to the platform 4.

For installation, the stand 4 has multiple portal frames 4-1.4-2.4-3
The upper surface of each frame has bolt holes for attaching the outer case 1 and the device mounting stand 5, and the legs of the frame have bolt holes for installing the frame itself. to drill.

Although the portal frame 4-1.4-2.4-3 is shown as being made of two members in the drawings, it goes without saying that it may be made of one piece.

In the above-mentioned installation, the stand 4 is placed, for example, across a side gutter 9 made along the railway line, and the legs are fixed to the side gutter wall with bolts 10.

This installation is done on a stand, and the equipment installation is done by attaching the stand 5 to the bolt 11.
It will be fixed in place.

Then, the outer case 1 is fitted on the outside, and the exposed part of the reinforcing frame 3 at the bottom of the case is similarly installed with bolts 1 on the top surface of the stand.
It will be fixed at step 2.

Therefore, for example, when replacing the outer case 1, by removing the bolts 12 fixing the reinforcing frame 3, only the outer case can be removed from the mounting base 4, so that the replacement can be easily performed.

When replacing equipment, the outer case can be removed and the equipment can be easily installed and removed from the stand 5 by removing the bolts 11 fixing the stand 5.

Since this invention is constructed as described above, the outer case,
The on-site replacement work for equipment is significantly simplified, and since only the items that require replacement need to be transported to the site, it becomes very easy and work efficiency can be greatly improved.

Another great advantage is that there is no need to stop various electrical functions when replacing them.

In addition, in the case of conventional equipment, there was no installation stand, so when installing a relay, etc., it was necessary to make an installation stand out of concrete, etc., whereas with this invention, the installation was done using a gate-shaped stand. Since it is constituted by a frame body, it has the advantage that the stand can be installed to straddle the side gutter by simply adjusting the size of the gate-shaped frame body to the width of the side gutter.

Furthermore, this invention has the effect of being structurally durable and safe.
