電気鉄道設備の諸作業において、近時、従来の梯子作業に変わるものとして、 軌道・陸上両用走行の作業車が導入されつつある。この軌陸式作業車は、車体の 前後下部両側に陸上走行用車輪を備えるとともに、車体中央下部にジャッキ式転 車装置を備え、車体の前後下部両側にガイド鉄輪を備えている。 Recently, work vehicles for both track and land use are being introduced as a substitute for conventional ladder work in the work of electric railway equipment. This track-and-rail type work vehicle is equipped with wheels for land running on both front and rear lower parts of the vehicle body, equipped with jack type rolling devices at the lower center of the vehicle body, and equipped with guide iron wheels on both front and rear lower parts of the vehicle body.
【０００３】 そして、上記軌陸式作業車を電気鉄道設備の諸作業において利用するには、踏 切において、軌陸式作業車を陸上走行用車輪により線路に対し、直角に侵入させ てジャッキ式転車装置を線路間の中央部に位置させ、この位置でジャッキ式転車 装置の作動により車体を上昇させて９０度回転させた後、下降させてガイド鉄輪 を線路に係合させることにより、軌陸式作業車をガイド鉄輪により線路に沿って 走行させることができる。また、作業完了後、軌陸式作業車を線路に沿って踏切 位置まで走行させ、ジャッキ式転車装置の作動により車体を上昇させて９０度回 転させた後、下降させることにより、陸上走行用車輪による走行により線路から 退線することができる。In order to use the above-mentioned track-and-rail type work vehicle in various works of electric railway equipment, at the railroad crossing, the track-and-rail type work vehicle is made to invade at right angles to the track by the wheels for land running, and the jack-type rolling stock is used. The device is located in the center between the tracks, and at this position, the jack type rolling device is operated to raise the car body and rotate it 90 degrees, and then it is lowered to engage the guide wheel with the track. The work vehicle can be driven along the track by the guide wheel. After the work is completed, the track-type work vehicle is run along the railroad track to the railroad crossing position, the jack-type rolling device is operated to raise the vehicle body, rotate it 90 degrees, and then lower it for land-based running. You can leave the track by running with wheels.

軌陸式作業車を利用するには、最終列車の通過、または列車運行間隔が比較的 長い時間帯、すなわち、夜間に制限される。しかしながら、軌陸式作業車は上記 のように踏切の位置で線路に対する入退線を行うため、踏切から作業現場までの 距離が長い場合には軌陸式作業車の往復移動に多くの時間を費し、作業時間に制 約を受ける。また、事故発生時等において、隣接線へ転線することができず、復 旧作業に時間を要するなどの問題がある。 To use a railroad work vehicle, the passage of the last train or train operation intervals are limited to relatively long hours, that is, at night. However, since the tracked work vehicle enters and leaves the track at the level crossing as described above, it takes a lot of time to reciprocate the tracked work vehicle when the distance from the level crossing to the work site is long. Be restricted in working time. In addition, when an accident occurs, there is a problem that it is not possible to roll to an adjacent line and it takes time for restoration work.
【０００５】 本考案は、上記のような従来の問題を解決するものであり、軌陸式作業車を踏 切以外の任意の箇所で線路に対して入退線させることができ、したがって、作業 実施上における時間の有効利用を図ることができるとともに、事故発生時におけ る早期復旧を図ることができ、また、軌陸式作業車の重量に耐える強度を有する とともに、軽量化を図り、したがって、敷設、回収の作業能率の向上および作業 員の省力化を図ることができるようにした軌陸式作業車用渡り板を提供すること を目的とするものである。The present invention solves the above-mentioned conventional problems, and allows a tracked work vehicle to be moved in and out of a track at any location other than a railroad crossing. In addition to being able to effectively use the time above, it is possible to achieve early recovery in the event of an accident, and it has the strength to withstand the weight of a track-type work vehicle and is also lightweight, and therefore laying, It is an object of the present invention to provide a bridge plate for a railroad work vehicle, which is capable of improving the work efficiency of collection and saving labor of workers.

This allows the track-and-rail type work vehicle to ride on the upper surface of the first and second crossover plates by using the sloped surface of the first crossover plate by the wheels for land running, and to make a straight entry into the track to make jack-type work. The car device is positioned above the second cross plate in the center of the track, and at this position the jack-type turn device operates to raise the car body and rotate it 90 degrees, then lower it to move the guide iron wheels. By engaging the track, the track-type work vehicle can be run along the track. In addition, the reverse operation of the above allows the track-type work vehicle to retreat from an arbitrary point on the track. In this way, the tracked work vehicle can be moved in and out of the track at any place other than the railroad crossing. Therefore, it is possible to make effective use of the time required for performing work, and to make an early recovery in the event of an accident. In addition, since the first and second crossover plates are filled with a hard plastic foam inside the reinforced plastic box body, it is possible to obtain the strength to withstand the weight of the tracked work vehicle and to reduce the weight. You can Therefore, it is possible to improve the work efficiency of laying and collection and save labor of workers.
