いて考慮されていない。すなわち、集電子ブロツ
ク４７の集電子ホルダ４８は、絶縁トロリー線４
０を両側からだき込む溝形形状となつている。 According to this configuration, the following problems occurred. In a system including a single insulated trolley wire 40 as shown in FIG. 7, the pitch between the wires is large, so there is no need to downsize the current collector 41, and conventionally no consideration has been given to downsizing. That is, the current collector holder 48 of the current collector block 47 is connected to the insulated trolley wire 4.
It has a groove shape with 0 inserted from both sides.
しかし、近年、複数本の導体を有する多線式の
絶縁トロリー線を用いることが要望されており、
この場合に、集電子ホルダ４８が溝形であると、
厚さ寸法が大きくて絶縁トロリー線の導体間ピツ
チを小さくすることができない。 However, in recent years, there has been a demand for the use of multi-conductor insulated trolley wires having multiple conductors.
In this case, if the current collector holder 48 is groove-shaped,
Due to the large thickness, it is not possible to reduce the pitch between the conductors of the insulated trolley wire.
また、集電子ホルダ４８が溝形であるため、そ
の重量も重くなり、集電子ブロツク４７が重くな

離線を防止するためには、大きな接触圧を必要と
するが、接触圧を大きくすると、それだけ集電子
４９の摩耗も早く、集電子４９の摩耗体積も大き
くしなければならなくなる。 Further, since the current collector holder 48 is groove-shaped, its weight is also heavy, and the current collector block 47 is also heavy. Therefore, separation from the track is likely to occur due to vibrations, impact force, etc. during running. Particularly, when the trolley wire 40 travels over a place with a difference in level, such as a connection portion of the insulated trolley wire 40, since the inertial force is large, the wire is likely to separate due to an impact or the like. In order to prevent this disconnection, a large contact pressure is required, but as the contact pressure is increased, the current collector 49 wears out faster, and the wear volume of the current collector 49 must also be increased.

A current collector for an insulated trolley according to the present invention is a current collector for an insulated trolley having a current collecting block, a rotating seat member, and a current collecting arm block, wherein the current collecting block has a U-shaped rotating member on the lower surface. The rotating seat member includes a current collector holder provided with a seat fitting notch and a current collector protruding from the upper end surface of the current collector holder, and the rotating seat member is a cylindrical member that is fitted into the rotating seat fitting notch and is prevented from coming out. The current collecting arm block includes a rotating seat having a shaped outer peripheral surface, and a shaft portion protruding downward from the rotating seat, and the current collecting arm block includes a cylindrical tip member into which the shaft portion is rotatably fitted, and a cylindrical tip member that connects the tip member. The present invention is characterized in that it includes a current collector arm that acts to urge the current collector upward, and that the upwardly protruding portion of the current collector and the current collector holder have approximately the same thickness. Therefore, the entire current collector can be made thin, and can also be used for multi-wire insulated trolley wires with small conductor spacing. Furthermore, since the current collector holder has approximately the same thickness as the current collector, it can be made lighter. Therefore, there is less wire separation due to vibrations during running, and the contact pressure with the insulated trolley wire can be reduced, resulting in a longer collector life.

is made to protrude from the upper end surface of the current collector holder 5, and a power supply line 6 is connected to the current collector 4. The current collector holder 5 is made of electrically insulating material such as synthetic resin,
It is integrally molded with the collector 4. The current collector 4 has a thin embedded part (not shown) embedded in the current collector holder 5 at the bottom, and an upwardly protruding part of the current collector 4;
It has approximately the same thickness as the current collector holder 5. As shown in FIG. 2, the current collector holder 5 has a rotary seat fitting cutout 7 cut out from its lower surface, and a pair of retaining protrusions 8 are formed on both sides of the inner surface thereof. Rotating seat member 2
The rotating seat 9 has a cylindrical outer peripheral surface, flanges 10 provided on both sides of the rotating seat 9, and a shaft portion 11 projecting downward from the rotating seat 9, which are integrally molded. The rotary seat 9 is fitted into the rotary seat fitting notch 7 of the current collector holder 5, and is prevented from coming off downward by the retaining protrusion 8. Note that the rotating seat 9 is assembled by being press-fitted between the retaining protrusions 8. The flange 10 is such that the current collector holder 5 is
This prevents the rotating seat 9 from shifting in the axial direction (thickness direction). The thickness of the rotary seat 9 and the thickness of the current collector holder 5 are made substantially equal. Flange 1
0 has a shape with a notched upper part, and the upper end surface 10a of the flange 10 is located below the top of the rotating seat 9. Current collector arm block 3
The two current collecting arms 12 are rotatably connected to a thick-walled cylindrical proximal end member 13 and a distal end member 14 with pins 15 and 16, forming a parallel link. The tip member 14 is connected to the shaft portion 1 of the rotating seat member 2.
1 is rotatably fitted into the shaft portion 11.
is secured at the lower end by a retaining ring (not shown). The base end member 13 is for inserting a mounting screw 17 for attachment to a moving load. A tension spring 18 is hung between both current collecting arms 12, and thereby the current collecting arm 12 receives a biasing force that causes the tip of the current collecting arm 12 to face upward.

されるのは、部材間の干渉による。Operation According to this configuration, the current collecting block 1 can move up and down around the rotating seat 9 of the rotating seat member 2 within the range of angle θ 1 (FIG. 3), and together with the rotating seat member 2, It can freely rotate left and right within the range of angle θ 2 (FIG. 4) with respect to the tip of the current collecting arm block 3. Furthermore, the vertical position of the current collector block 1 is variable by the vertical movement of the current collecting arm 12, and the current collecting arm 12 is rotated left and right at an angle θ 3 . These movements ensure that the current collector 4 always makes proper contact with the conductor 21 of the insulated trolley wire 20 even if the relative position or angle between the current collector and the insulated trolley wire 20 changes during running. can be used to collect current. Note that the reason why the rotation angles (θ 1 to θ 3 ) of each part are restricted to a certain range is due to interference between members.

いる。 Although it operates in this manner, this configuration provides the following advantages. That is, current collector block 1
Since the current collector holder 5 is made approximately the same width as the current collector 4, the overall thickness is thinner, and even when the distance between the conductors 21 is small, as in the case of the multi-wire insulated trolley wire 20 shown in FIG. Fully usable. In addition, since the current collector holder 5 has approximately the same thickness as the current collector 4, it can be lighter in weight compared to the conventional groove-shaped one that surrounds the current collector. Therefore, disconnection due to vibrations and the like during running is reduced, and the contact pressure with the insulated trolley wire 20 can be reduced, reducing wear on the current collector 4 and extending its life. Further, since the diameter of the rotary seat 9 can be made large, wear of the rotating contact portion between the rotary seat 9 and the current collector block 1 is small. Furthermore, since the movable parts of the current collector block 1 and the rotary seat 9 are made of resin material, they have good sliding properties and excellent wear resistance.

In the current collector of the insulated trolley of this invention, the current collector holder of the current collector block has approximately the same thickness as the current collector, so the overall thickness can be made thinner, and multi-wire insulation with small conductor spacing can be used. Trolley wires can also be used. In addition, since the collector holder is made to have approximately the same thickness as the collector, it is lightweight, and stable contact can be achieved during running.Moreover, the contact pressure against the insulated trolley wire can be reduced, reducing wear on the collector. There is an effect.

Therefore, even if the relative position between the current collector and the insulated trolley wire changes, a stable contact state is maintained. Furthermore, since the diameter of the rotary seat can be made large without increasing the shape, there is an advantage that wear of the rotating contact portion between the rotary seat and the current collector block is reduced. Further, the rotary seat member has a structure in which the shaft portion thereof is fitted into and held by the tip member. Therefore, when the rotating seat is worn out, the rotating seat member can be easily replaced.
