Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a protection device for a train number receiving coil installed in a track for controlling train operation through centralized control in an operation control room.

Conventional Technology The operation of high-speed trains such as Shinkansen trains is centrally controlled by an operation control center for security reasons. As a control means, a train number is set for each train, and train number receiving coils are installed at key points on the track to confirm the running position of the train.

As shown in FIG. 2, this train number receiving coil 11 is constructed by installing a base 14 made of a steel framework in the track bed between the left and right rails 21, and attaching a rectangular frame coil base 12 to this base 14. , a coil is arranged on this coil stand. 13 in the figure indicates a marker coil.

In addition, in snowy areas, sprinklers are installed at key points on the tracks to spray warm water onto the tracks and onto moving trains to prevent snow accumulation and freezing and to ensure smooth train operation.

Problems to be Solved by the Invention During snowfall, when a train runs through a location where the above-mentioned sprinklers are installed, the snow is removed by spraying hot water from the sprinklers toward the train. At this time, water droplets from the sprinkler and snow adhere to the area under the floor of the vehicle, forming snow and ice blocks (hereinafter referred to as adhesion blocks).

These adhered lumps are peeled off from the train due to vibrations, wind pressure, etc. while the train is running at high speed, and fall into the track with great acceleration.

The falling point was the installation point of the train number receiving coil, and if the receiving coil were to be hit directly, the coil and coil stand would receive a large impact and be damaged, potentially interfering with the safe operation of the train. However, conventionally, no measures have been taken to protect the train number receiving coil from falling adhered lumps.

In view of the current situation, this invention provides a protection device for preventing damage to the train number receiving coil due to falling lumps attached to the train.

Means for Solving the Problems In order to achieve the above object, the protective device of this invention includes a plate-like member 2 having an inclined surface 3 formed at the upper part of the front side surface and a cutout step part 4 provided at the upper part of the rear side surface. A plurality of collars 5 are arranged in parallel at predetermined intervals, and collars 5 are arranged between adjacent plate-like members.
A plurality of long bolts 7 are connected to each plate by placing the mounting bracket 6 in the space between the adjacent plate members facing the base supporting the train number receiving coil 11 installed in the track. The bolt holes provided in the shaped member 2 are connected to the bolt holes provided in each collar 5 and the mounting bracket 6 for assembly, and the cutout stepped portion 4 is incorporated into the train entry side end surface of the coil stand 12 of the train number receiving coil. The mounting bracket 6 is configured to be attached to the base.

Function: When a lump of material adhering to a vehicle during snow removal falls during subsequent high-speed driving and attempts to directly hit the train number receiving coil, it collides with the protection device of this invention and causes damage to the adjacent plate. Either they bite into the spaces between the members and are held there, or they collide with the plate-like members and are crushed and scattered into the orbit. Therefore, a collision with the receiving coil can be avoided, and damage to the coil can be prevented.

The angle of inclination of the inclined surface 3 provided on the plate-shaped member is not limited, but must be an angle at which the adhered lumps falling from a train running at high speed can be reliably crushed and scattered without directly colliding with the train number receiving coil. That's fine.

Further, it is preferable that the plate member 2 is made of a lightweight olefin plastic, such as polyethylene, which has excellent wear resistance, heat resistance, and low temperature resistance.

Note that if this protection device is installed along the end surface of the marker coil 13 on the train entry side, the marker coil can be protected from falling objects.

Embodiment The details of this invention will be explained based on the embodiment shown in FIG.

The protection device 1 includes a plurality of plate-like members 2 each having an inclined surface 3 formed at the upper part of the front side surface and a cutout stepped part 4 provided at the upper part of the rear side surface, which are arranged in parallel at a predetermined interval, and between adjacent plate-like members. A collar 5 is interposed. And left and right rails 21
Train number receiving coil 11 installed on the track bed between
A mounting bracket 6 having an L-shaped cross section is installed in the space between adjacent plate-shaped members facing the part of the base 14 that supports the train entrance side (the figure shows the case formed of a pair of L-shaped steel). , pass three long bolts 7 sequentially through the bolt holes provided in each plate-shaped member 2, each collar 5, and the bolt hole provided in the mounting bracket 6, and assemble the bolts, screwing nuts 8 onto the ends of the bolts, Concluded and constituted.

The above protection device 1 includes a train number receiving coil 11
On the train approach side, the notch step 4 is overlapped with the end face of the coil stand 12, and the bolt 15 is screwed between the mounting bracket 6 placed on the base 14 and the base. is attached to the end face of the train number receiving coil 11 on the train entry side.

Effects of the invention If the protection device of this invention is installed along the end face of the train approach side of the train number receiving coil, even if a lump of ice or snow falls from a running train, it will be caught by the protection device and directly Collision with the coil stand is prevented. As a result, damage to the train number receiving coil can be prevented, contributing to safe train operation.
