外装的構成により感電防止効果の実をあげるにある。In order to achieve this objective, the present invention aims to significantly reduce the running resistance of the conventional brush type by making the contact collector a rolling roller type.Furthermore, the roller type collector's bearings on both sides are divided into two. By partially fitting into the insulated bearing seat, the structure is made tighter and the workability is improved.Furthermore, the external structure of the insulated bearing seat is effective in preventing electric shock. .

が細かく行われうるところから、極めて合理的、経済的
となしうるものである。Such a configuration is extremely rational and economical since it is easy to assemble and disassemble regardless of the fact that the collector is of the transfer roller type, and partial repairs can be made in detail.

まづ、第１図において従来の絶縁トロリーバー用コレク

ダーＢＨの突軸Ｓを介してクレビスなるＵ字状金具Ｕに
掛合して俯仰自在に支持される。First, if we look at the conventional insulated trolley bar collector in Fig. 1, the current collector brush Br is attached to the insulated brush holder B.
The holder BH is brought together from both sides by the holder BH and fixedly integrated, and is engaged with a U-shaped metal fitting U, which is a clevis, through the protruding shaft S of the holder BH, and is supported so as to be able to rise and fall freely.

リードワイヤーＷはブラシＢｒの一部に固着されて走行
集電架構ＣＯに導びかれる。The lead wire W is fixed to a part of the brush Br and guided to the traveling current collection frame CO.

上下左右に回動自在な支持腕Ａｒには操作杆Ｒが取付け

生ずる欠点があり、また片すべり等のことで良好な接触
状態を保ち難い欠点もあった。By the way, in this type in which the brush Br moves by sliding, the brush itself is usually made of carbon-based material, and has the disadvantage that it is subject to significant wear and tear during operation, often requiring replacement, and also suffers from one-sided slipping, etc. There was also the drawback that it was difficult to maintain good contact conditions.

子９を固着する。In addition, to explain in more detail the assembly and combination of each of the above parts, one end (left end) of the shaft 2 into which the transfer roller type current collector 1 is loosely fitted is fixed to the bearing metal 3 side, and the shaft 2 on the 4 side is simply fitted. A current collector terminal 9, such as a crimp type pipe terminal, is fixed to the lower surface of the bearing stand 3.

また、軸受金３および４は絶縁軸受座５および６の互い

あることが理解される。Looking at this as a whole with reference to Figure 2, it can be seen that the transfer roller type current collector 1 is hidden between the insulating walls and exhibits the transfer current collection function and is completely safe. From the scales 5 and 6 secured at predetermined positions, it is understood that there is a solid construction in which the required center position of the current collector 1 can be secured without any compromise.

て、点検も、補修も著しく容易に行うことができる。In addition, when inspecting or repairing, simply remove the contact plate 10 from the trolley bar, and the integrated current collector becomes free from the running current collector frame. If the collector 1 is separated one by one from the shaft 2, the entire contents can be seen at a glance, and inspection and repair can be carried out with great ease.

ない。Conventionally, roller-type collectors are common for bare To-01J- wires, but because the live parts are exposed, there is a limit to their application inside structures.On the other hand, collectors for insulated trolley bars are insulated. Although it is protected, since it is a fixed brush type, the running resistance is large, and when used as a hand hoist, the running resistance is especially large, requiring force, and the workability is not good.

そこに問題がある。In this case, it is not possible to use a roller-type collector for bare trolley wires because it is easy for people to get close to the feeder line.
Therein lies the problem.

本考案は以上のごとくして、この問題を解決したもので
ある。The present invention solves this problem as described above.

すればよい。The above explanation is about one embodiment of the present invention, but if you want to increase the load capacity, you can install two roller type collectors in parallel to one insulated bearing seat in the same way, and connect the current collector terminals. 71J-bar, so that both roller type collectors can be brought into contact with the insulating bar (71J-bar) and rolled at the same time.

その他任意の変形がありうる。Any other variations are possible.
