Description

特許法第30条第2項適用 第6回鉄道技術展 幕張メッセにて、2019年11月27日から2019年11月29日まで展示Article 30, Paragraph 2 of the Patent Law applies Exhibited at the 6th Railway Technology Exhibition Makuhari Messe from November 27, 2019 to November 29, 2019

本発明は、運搬用台車に関する。 The present invention relates to a cart for transportation.

従来から、電車のレールや枕木の交換、その他各種の軌道整備・補修工事には、「軽便トロ(トロッコ)」と呼ばれる運搬用軌道走行台車が使用されている。
真夜中に電車が全く走行しなくなる状況を、一般に、“線路閉鎖”と呼ばれているが、この“線路閉鎖”は、夜の1時頃から早朝5時頃までに行われる。
即ち、上記軌道整備・補修工事は、夜間の短い“線路閉鎖”の時間内にて行う必要がある。上記“線路閉鎖”がかかるまでは、軌道上に侵入できない。それまで上記「軽便トロ」を、踏切の前等に於て、待機させて、“線路閉鎖”がかかるのを待ち、“線路閉鎖”がかかると、「軽便トロ」を複数の作業者にて持ち上げて、踏切上で載線し(軌条上に載置し)、必要な作業装置や道具、使用資材を、積込み、現場まで人力で押してゆく必要があった。
BACKGROUND ART Traditionally, a track-running truck for transportation called a "light truck" has been used for replacement of train rails and sleepers, and for various other track maintenance and repair work.
A situation in which trains do not run at all in the middle of the night is generally called "track closure".
That is, it is necessary to carry out the track maintenance/repair work during the short "track closure" period at night. You can't enter the orbit until the above "track closure" is applied. Until then, the above-mentioned "Kairen Toro" is put on standby in front of a railroad crossing, etc., and waits for the "track closure". It had to be lifted, placed on rails at a railroad crossing, loaded with the necessary work equipment, tools, and materials, and manually pushed to the site.

このように、従来の「軽便トロ」は、作業者にとって、短い時間で、載線せねばならず、かつ、作業装置や道具、使用資材を積込まねばならず、過酷な作業を要求され、しかも、夜間に工事できる貴重な短い時間を無駄使いしていた。
そこで、従来、軌条に載せ易く、かつ、路面と軌条両用の運搬台車が提案されている(特許文献1参照)。
As described above, the conventional "Lightweight Toro" required a worker to mount the work in a short period of time, and to load the work equipment, tools, and materials to be used. What's more, they were wasting the precious short time that could be spent working at night.
Therefore, conventionally, there has been proposed a carriage that can be easily placed on a rail and that can be used both on the road surface and on the rail (see Patent Document 1).

特開2002-178926号公報JP 2002-178926 A

前記特許文献1に記載の運搬台車は、台車本体に、路面用キャスタと、軌条用キャスタとを、別々に取付け、かつ、コイルバネを付設して、人力で路面から軌条へ載せ易くする構成である。 The carriage described in Patent Document 1 has a configuration in which road surface casters and rail casters are separately attached to the carriage body, and coil springs are attached so that it can be easily placed on the rail from the road surface by human power. .

しかしながら、このような運搬台車は、小型の軽便用としては使い易いのであるが、軌道整備・補修工事にあっては、重量の大きい作業装置や道具、使用資材等を、載置し、かつ、長い距離のある現場まで運ぶには、不十分であった。
そこで、本発明は、比較的重量の大きい作業装置や道具、使用資材等を載置可能であって、“線路閉鎖”の前に踏切の前の路面等に於て積込完了状態としておき、“線路閉鎖”となるや否や、容易に路面走行して、(路面と軌条の交差する)踏切に於て、軌道に乗り換え、直ちに、軌道上を動力走行して、楽に現場まで到達可能として、作業者の負担軽減を図り、さらに、軌道現場作業時間の有効活用を目的とする。
However, although such a carriage is easy to use as a small and convenient vehicle, in track maintenance and repair work, heavy work equipment, tools, materials, etc. It was inadequate to carry to a site with a long distance.
Therefore, according to the present invention, it is possible to place relatively heavy working equipment, tools, materials, etc., and complete loading on the road surface before the railroad crossing before closing the track. As soon as the track is closed, it can easily run on the road surface, change to the track at the railroad crossing (where the road surface and the rails intersect), immediately drive on the track with power, and easily reach the site. The purpose is to reduce the burden on workers and to make effective use of track site work time.
