Equipped with two connected rollers (front and rear wheels) and a roller pulling mechanism on both the front and rear wheels or the rear wheel, the rollers use the signal applied to an obstacle such as an overhead power line damper or the resistance to overcome the obstacle. This is because the rollers can be forcibly pulled up to overcome obstacles such as dampers by detecting the signal.

なり、通常の状態となる。The front part of the running gear (20
) detects with a sensor or switch (50) that the front wheel (21) of the drive roller is applied to or approaches the damper (2) as shown in FIG.
When the electromagnetic clutch (26) of the roller lifting mechanism (23) installed at the top is activated, as shown in Fig. 2,
A reel (27) interlocked with an electromagnetic clutch (26) rotates. As a result, the rope or wire (28) connected to the front wheel (21) is wound up, and the front wheel (21) is forcibly pulled upward. As a result, the front wheel (2I) is replaced by the rear wheel (22
) as a fulcrum and moves forward while being lifted upward, making it possible to run over the damper (2). At this time, the sensor or switch (5!) detects that the front wheel (21) has risen to a certain extent, and the electromagnetic clutch (
By cutting off the signal to 26), the front wheel (21) will be located on the overhead wire (1), as shown in FIG. 3, and will be in a normal state.

ー（２）の乗越えが可能となる。Similarly, by providing a roller lifting mechanism (24) on the rear wheel (22), it becomes possible for the rear wheel (22) to ride over the damper (2) in the same way as the front wheel.
上記引上げ機構（２３）（２４）を作動させる方法は、
ラノオコントロール等によってマニュアル操作も可能で
ある。The method for operating the above-mentioned pulling mechanisms (23) and (24) is as follows:
Manual operation is also possible using Ranoo Control, etc.
（実施例）
第４図及び第５図は本発明の架空電線上走行装置の他の
具体例の説明図である。(Embodiment) FIGS. 4 and 5 are explanatory diagrams of other specific examples of the overhead wire running device of the present invention.
本具体例においてはローラ引上げ機構は後輪ローラのみ
に装備しており、比較的軽度なダンパーの乗越え走行に
適している。In this specific example, the roller lifting mechanism is provided only on the rear wheel roller, and is suitable for running over a relatively light damper.
架空電線（１）上を走行してきた走行装置は前部駆動ロ
ーラ（２０）の前輪（２１）がダンパー（２）に掛ると
、第４図のようにダンパー（２）上に乗上げることが出
来るが、後輪（２２）がダンパー（２）に掛ると前輪（
２Ｉ）が後輪（２２）を支点にして上方に浮き上がり、
ダンパー（２）を乗越えることが出来ない。When the front wheel (21) of the front drive roller (20) of the traveling device traveling on the overhead power line (1) hits the damper (2), it may run onto the damper (2) as shown in Fig. 4. It can be done, but when the rear wheel (22) hits the damper (2), the front wheel (
2I) floats upward using the rear wheel (22) as a fulcrum,
Unable to get over damper (2).

抗力が緩和され、同図■のように前輪（２１）はダンパ
ー（２）を乗越えることが出来る。If this occurs diagrammatically as shown in Figure 6, when resistance is generated on the front wheel (21) by the damper (2), the rotation direction of the drive roller causes the rear wheel (22) to move as shown in Figure 6. The front wheel (21) acts in the direction of pushing down, and the reaction force causes the front wheel (21) to move as shown in the figure.
The front wheel (21) is lifted upward as shown in the figure, the resistance force against the damper (2) is relaxed, and the front wheel (21) is able to ride over the damper (2) as shown in (2) in the figure.
一方、後輪（２２）にダンパー（２）の抵抗が生じると

作用し、その反力で後輪（２２）は同図■のように下方
に下がり、ダンパー（２）に対する抵抗力が増加し、後

。On the other hand, when the rear wheel (22) encounters resistance from the damper (2), a force acts in the direction of pushing up the front wheel (21) as shown in (■) in the same figure, and the reaction force causes the rear wheel (22) to move upward as shown in (■) in the same figure. , the resistance force against the damper (2) increases, and the rear wheel (22) cannot ride over the damper (2).

に強制的に引上げる（第６図■）。Therefore, as shown in Fig. 5, when the sensor or switch (52) detects a signal that the front wheels (2) have lifted up, the rear wheels (2)
22) The electromagnetic clutch (26') of the roller lifting mechanism (24) at the top operates, and the reel (27'
' ) rotates. As a result, the rope (28'') connected to the rear wheel (22) is wound up, and the rear wheel (22) is forcibly pulled upward (Fig. 6 (■)).
なお第６図の（１４）は前後輪に動力を伝達する歯車で
ある。Note that (14) in FIG. 6 is a gear that transmits power to the front and rear wheels.
後輪（２２）が持上げられた反動で前輪（２Ｉ）は下方
に移動して架空電線（１）上に移動して走行する一方、
後輪（２２）は前輪（２１）を支点に上方に持上がった

ラッチ（２［ｉ’ ）への信号を断つことによって前輪

（１）上を走行する。The front wheels (2I) move downward due to the reaction of the rear wheels (22) being lifted and move onto the overhead power lines (1), while running.
The rear wheel (22) moves upward with the front wheel (21) as a fulcrum. This causes the rear wheel (22) to move to the damper (
The resistance to overcome the damper (2) is reduced, making it possible to overcome the damper (2). At this time, the sensor or switch (52) detects a signal that the rear wheel (22) has lifted up, and by cutting off the signal to the electromagnetic clutch (2[i'), the front wheel (21) and the rear wheel (22) are moved normally. The vehicle then travels on the overhead power line (1).

引上げ機＋１（３４）を設けることによって、装置の後
部駆動ローラ（３Ｇ）もダンパー（２）を乗越えての走
行が可能となる。Similarly, by providing the same puller +1 (34) to the rear wheel (3I) of the rear drive roller (3G), the rear drive roller (3G) of the device can also run over the damper (2). .
なお、ローラ引上げ機構を作動及び停止させる信号は例

ある。また上記実施例では駆動ローラは４輪用いたがさ
