本発明は、側あおりの少なくとも一部分に伸縮可能な伸縮式側あおりを設けた軌陸車に関する。 TECHNICAL FIELD The present invention relates to a land rail vehicle that is provided with a telescoping type side door that is extendable and retractable on at least a portion of the side door.
軌陸車は、タイヤ輪で道路上を走行する形態と、鉄輪で軌道上を走行する形態とに択一的に切換え可能なトラックのような車両であり、鉄道の線路の補修や点検等に使用される。
通常の軌陸車やトラックでは、荷台の３辺に左右の側あおりと後部あおりとが装備され、荷物の積み込みや荷下ろしの際には、左右何れか一方の側あおりや後部あおりを回動させて下方へ垂らした状態に開放され、荷物の積み込みや荷下ろし終了後にはそれらの側あおりや後部あおりが元の状態に閉じられる。
A track vehicle is a truck-like vehicle that can be switched between running on roads with tires and running on tracks with iron wheels, and is used for repairing and inspecting railway tracks. be done.
Ordinary land rail cars and trucks are equipped with left and right side doors and rear doors on three sides of the loading platform, and when loading or unloading cargo, the side doors or rear door on either the left or right must be rotated. After loading and unloading cargo, the side doors and rear doors are closed to their original positions.
通常の軌陸車やトラックの側あおりは、荷台上に荷物を収容する機能を発揮できればよいため、側あおりの上下幅は一定で上下幅が変化する構造には作られてはいない。
尚、参考までに、特許文献１には、側あおりを開閉する作業負荷を軽減可能にした、自動車用荷台側あおりの開閉補助装置が開示されている。
The side doors of ordinary land rail cars and trucks only have to function to accommodate cargo on the loading platform, so the vertical width of the side doors is constant and they are not designed to vary.
For reference, Patent Document 1 discloses an opening/closing auxiliary device for an automobile loading platform side door, which makes it possible to reduce the workload of opening and closing the side door.
軌陸車の場合、軌道上の軌陸車の荷台から駅のホーム上へ又はその反対に資材を運んだり、作業員が移動したりする必要があるが、従来の軌陸車では、荷台から駅のホーム上へ足場板やその他の板材を架設することで、上記のニーズに対処していた。
本発明の目的は、側あおりの少なくとも一部分に伸縮可能な側あおりを設け、その伸縮式側あおりを荷台とホームとの間のスライドスロープとして利用可能にした軌陸車を提供することである。
In the case of a land-rail vehicle, it is necessary to transport materials or move workers from the loading platform of the land-rail vehicle on the tracks to the station platform or vice versa, but with conventional land-rail vehicles, it is necessary to move from the loading platform to the station platform. The above needs were addressed by erecting scaffolding boards and other planks on top.
An object of the present invention is to provide a land rail vehicle in which at least a portion of the side gate is provided with an extendable side gate, and the telescopic side gate can be used as a slide slope between the loading platform and the platform.
請求項１の軌陸車は、タイヤ輪で道路上を走行する形態と、鉄輪で軌道上を走行する形態とに択一的に切換え可能な軌陸車において、荷台部の少なくとも左右何れか一方の側あおりの長さ方向の少なくとも一部分に、上下幅拡大方向へ伸縮可能な伸縮式側あおりを設け、前記伸縮式側あおりの下端部を側あおりのベース部材であって荷台部に回動可能に連結されたベース部材に水平軸心回りに回動可能に連結する連結機構を設け、前記伸縮式側あおりを伸長状態に切換え且つ車幅方向外側へ９０°以上回動させることで、前記伸縮式側あおりがスライドスロープとなるように構成し、前記伸縮式側あおりが、３段に伸縮する３段伸縮構造を有することを特徴としている。 The land-rail vehicle of claim 1 is a land-rail vehicle that can be selectively switched between a mode in which it runs on roads with tire wheels and a mode in which it runs on tracks with iron wheels, at least on either the left or right side of the loading platform. A telescoping side gate that can be expanded and contracted in the vertical width expanding direction is provided in at least a portion of the length of the gate, and the lower end of the telescoping side gate is rotatably connected to the cargo platform that is the base member of the side gate. A connecting mechanism is provided to connect the base member rotatably around a horizontal axis, and the telescoping side gate is switched to an extended state and rotated by more than 90 degrees outward in the vehicle width direction. It is characterized in that the flap is configured to be a slide slope , and the telescoping side flap has a three-stage telescopic structure that extends and contracts in three stages .
上記の構成によれば、前記伸縮式側あおりをスライドスロープとして使用する場合には、前記伸縮式側あおりを伸長状態に切換え、前記連結機構を介して前記側あおりのベース部材に対して水平軸心回りに車幅方向外側へ９０°以上回動させてスライドスロープとする。
伸縮式側あおりをスライドスロープとして使用することができるため、軌陸車の荷台部とホームとの間の交通のため足場板を架設する等の労力を解消することができる。
前記伸縮式側あおりは、収縮状態にして側あおり内に収容できるため邪魔になることもない。
更に、前記伸縮式側あおりは３段伸縮構造を有するため、伸長状態における伸縮式側あおりの上下幅を大きくすることができる。
According to the above configuration, when the telescoping side gate is used as a slide slope, the telescoping side gate is switched to the extended state, and the horizontal axis is connected to the base member of the side gate via the connection mechanism. Rotate the slider around the center outward in the vehicle width direction by more than 90° to create a slide slope.
Since the telescoping side gates can be used as slide slopes, it is possible to eliminate the labor involved in erecting scaffolding boards for transportation between the loading platform of the land rail vehicle and the platform.
The telescoping side gate can be stored in the side gate in a contracted state, so it does not get in the way.
Furthermore, since the telescopic side gate has a three-stage telescopic structure, the vertical width of the telescopic side gate in the extended state can be increased.
一方、前記伸縮式側あおりをスライドスロープではなく通常の側あおりとして使用する場合は、前記側あおりのベース部材と共に側あおりを回動させることで開閉することができる。 On the other hand, when the telescoping side gate is used as a normal side gate instead of a slide slope, the side gate can be opened and closed by rotating the side gate together with the base member of the side gate.
請求項２の軌陸車は、請求項１の発明において、前記伸縮式側あおりを伸長状態にロック可能なロック機構を設け、前記ロック機構のロック部材を手摺の手摺支柱で構成したことを特徴としている。
上記の構成によれば、前記伸縮式側あおりをロック機構により伸長状態にロック可能であり、そのロック機構のロック部材を手摺の手摺支柱で構成したため、部材数を少なくして製作費を低減することができる。

Next, the function and effect of the side gate 20 of the land rail vehicle 1 explained above will be explained.
When using the telescoping side gate 23 as a slide slope, the telescoping side gate 23 is switched to the extended state, and the base member 20a of the side gate 20 is moved in the vehicle width direction around the horizontal axis via the coupling mechanism 26. Rotate outward by more than 90 degrees to create a slide slope.
In this way, since the telescopic side gate 23 can be used as a slide slope, it is possible to eliminate the labor involved in erecting a scaffolding board for transportation between the loading platform 4 of the land-rail vehicle 1 and the platform H. can.
伸縮式側あおり２３は、収縮状態にして１段目部材２３ａ内に収容できるため邪魔になることもない。一方、伸縮式側あおり２３をスライドスロープではなく通常の側あおりとして使用する場合は、非伸縮式前部側あおり２１や非伸縮式後部側あおり２２と共に、側あおり２０のベース部材２０ａと一体的に伸縮式側あおり２３を回動させることで開閉することができる。 The telescoping side gate 23 can be stored in the first stage member 23a in a contracted state, so that it does not get in the way.

It can be opened and closed by rotating the telescoping side gate 23.
しかも、伸縮式側あおり２３をロック機構３０により伸長状態にロック可能であり、そのロック機構３０のロック部材３０ａを手摺の手摺支柱で構成したため、部材数を少なくして製作費を低減することができる。
また、伸縮式側あおり２３が３段伸縮構造を有するため、伸長状態における伸縮式側あおり２３の上下幅を大きくすることができる。
Moreover, the telescoping side gate 23 can be locked in the extended state by the locking mechanism 30, and the locking member 30a of the locking mechanism 30 is composed of the handrail support of the handrail, so the number of parts can be reduced and manufacturing costs can be reduced. can.
Further, since the telescopic side gate 23 has a three-stage telescopic structure, the vertical width of the telescopic side gate 23 in the extended state can be increased.
特に、側あおり２３の長さ方向中央部分に伸縮式側あおり２３を設け、伸縮式側あおり２３をスライドスロープとした場合には、軌陸車１の荷台４の中央部にアクセスしやすくなる。 In particular, when the telescoping side gate 23 is provided at the central portion in the length direction of the side gate 23 and the telescoping side gate 23 is made into a sliding slope, it becomes easier to access the center portion of the loading platform 4 of the land rail vehicle 1.
