The lower end of 6 is rotatably supported at a distance equal to that of the connecting link, and the whole has a parallelogram shape. 1
9 is a main shaft of the lower frame 15, 20 is a main shaft lever fixed to the main shaft 19, and 21 is a direct-acting motor installed insulated from the underframe 19. Here, a direct-acting motor is a motor with l-
Combine the screws into one piece! When the motor is rotated, the output shaft moves in and out in the axial direction. It is an electric device with a holding brake and is similar to commonly known and commercially available devices. 22 is an output shaft of the direct-acting motor 21, which expands and contracts in the axial direction of the motor as the direct-acting motor 21 rotates forward and backward. 23 is an insulating rod that connects the output shaft of the direct-acting motor and the main shaft lever; 24 is an outer cylinder of a support device that is fixed to the connecting link 17 and maintains the vertical position regardless of whether the current collector is raised or lowered; 25 is an outer cylinder of the current collector boat; Support spring, 26, collector boat, 27

ある。32 is a switch for raising and lowering the current collector, and 33 is a power source.
次に、かような構或からなる本装置の作用について説明
する。Next, the operation of this device having such a structure will be explained.
集電舟26の上面はトロリ線12に例えば押上力5.5
kgで接触しており、トロリ線12との接触力すなわち
押上力によって支持ばね25がたわんでいるので、磁石
リング28は上げ検知スイ,チより下部の位置にある。The upper surface of the collector boat 26 is applied to the contact wire 12 with a pushing force of 5.5, for example.
kg, and the support spring 25 is bent by the contact force with the contact wire 12, that is, the upward force, so the magnet ring 28 is located at a lower position than the lift detection switch.
電車が走行してトロリ線12の高さが上がると、集電舟
26および支持棒27は追従して上昇し、ある程度以上
上がると磁石リング28により上げ検知スイ,チ30が
働らき、直動電動機21が起動して出力軸22が引込み
、絶縁棒23および主軸テコ加を介して主軸l9を回転
させ果電装置枠組や検知スイッチは上昇する。When the train runs and the height of the contact wire 12 rises, the collector boat 26 and the support rod 27 follow and rise, and when it rises above a certain level, the magnetic ring 28 activates the lift detection switch 30, and the linear motion The electric motor 21 is started, the output shaft 22 is retracted, the main shaft 19 is rotated through the insulating rod 23 and the main shaft leverage, and the power output device framework and the detection switch are raised.
上昇してトロリ線12と集電舟26の接触力が所定の値
すなわち5.5kgに達すると支持ばね25がたわむの
で、上げ検知スイッチ30がOFFするので直動電動機
21が停止する。またトロリ線12の高さが低くなると

接触力が減少すると、支持ばね25が伸び、下げ検知ス
イ,チ31をOFFにして直動電動機21は停止し、枠
組の下降は止まる。When the contact force between the contact wire 12 and the current collector boat 26 reaches a predetermined value, that is, 5.5 kg, the support spring 25 is bent, and the lifting detection switch 30 is turned off, so that the linear motor 21 is stopped. Further, when the height of the contact wire 12 becomes lower, the support spring 25 is bent, and the magnet ring 28 is lowered, turning on the detection switch 31, so the linear crawler 21 is activated.
The output shaft 22 comes out, rotates the main shaft 19 in the downward direction, and the framework descends. When the framework is lowered and the contact force between the contact wire 12 and the current collector boat 26 is reduced, the support spring 25 is extended, the lowering detection switch 31 is turned OFF, the linear motor 21 is stopped, and the lowering of the framework is stopped.
このようにトロリ線12の上下変位に追従する集電舟2
6の上下により、枠組が上昇,下降を行い良好な集電状
態を維持する。In this way, the current collector boat 2 follows the vertical displacement of the contact wire 12.
The framework moves up and down by moving up and down 6 to maintain a good current collection state.

extends and lowers the framework to the folded position. At the folding position, a limit switch (not shown) that detects the output shaft or frame position detects that the frame has descended to a predetermined position, and turns off the linear motor 21.
集電装置が折り畳んだ状態では、集電舟26はトロり線

検知スイッチ30はON状態となっているのでスイ,チ
32を上げ方向に投入すると、集電装置は上昇し、トロ
リ線12に接触して第1図の状態に戻る。When the current collector is folded, the current collector boat 26 has no contact force with the contact wire 12, so the lift detection switch 30 is in the ON state as shown in FIG. When turned on in the upward direction, the current collector rises, contacts the contact wire 12, and returns to the state shown in FIG. 1.
なお、第1図においては直動電動機21の電源33とし
て直流を使用した場合を示したが、直動電動機2lとし

チ32の部分を変更することによって全く同じ機能が得
られることは明らかである。Although FIG. 1 shows the case where DC is used as the power source 33 of the direct-acting motor 21, even if an induction motor is used instead of a direct-current motor as the direct-acting motor 2l, by changing the switch 32. It is clear that exactly the same functionality is obtained.
また、本実施例では直動電動機21により集電装置主軸

装置と同様である。Furthermore, in this embodiment, the linear motor 21 applies rotational moment to the main shaft of the current collector to move the current collector up and down. The function is also similar to the device of the present invention.

Furthermore, since it is an all-electric type, it is possible to perform active control of follow-up by using an appropriate contact wire position detection means, which will have great benefits in the future.
