Japanese Utility Model Publication No. 3-111101

  This type of trolley conductor is in sliding contact with the current collector of the trolley while a certain pressing force is applied. Therefore, due to the plastic flow of the metal material forming the trolley conductor, particularly at both ends in the width direction of the sliding contact surface. In some cases, burrs and whiskers (a lump of spine or fibrous metal conductor) may occur.

  In order to remove these burrs and whiskers more effectively, it is effective to increase the pressing force of the conventional trolley conductor cleaner against the trolley conductor, but this will promote the wear of the trolley conductor and cleaner brush. As a result, the service life of the trolley conductor and the cleaner may be shortened and the replacement frequency may be increased.

  Then, an object of this invention is to obtain the trolley conductor cleaner which can remove a burr | flash, a beard, etc. more effectively, suppressing abrasion of a trolley conductor or a cleaner.

In the invention of claim 1, there is provided a trolley conductor cleaner comprising a reciprocating drive mechanism that presses a bristle tip portion of the brush against the trolley conductor and vibrates the brush along the extending direction of the trolley conductor. The long hair region having a long length and the short hair region having a short hair length are formed at the center of the extending direction so that the long hair region wider than the width of the trolley conductor is formed, and the trolley is formed at both ends of the extending direction. A side surface facing the reciprocating direction is formed at the tip of the long hair region by partitioning and arranging the short hair region wider than the width of the conductor .

  According to the invention of claim 1, by arranging the long hair region in which the pressing force is increased and the short hair region in which the pressing force is decreased, the brush having a uniform hair length as in the past is provided. As compared with a case where the pressing force is increased, it is possible to more effectively remove burrs, whiskers, and the like while suppressing an increase in the overall pressing force and reducing the amount of wear. Further, since the sliding resistance of the cleaner with respect to the trolley conductor is reduced, there is an advantage that the cleaner can be easily moved along the extending direction of the trolley conductor.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a trolley duct in which a trolley conductor as a cleaning target of a trolley conductor cleaner according to the present embodiment is installed, a trolley for obtaining power supply power from the trolley duct, and a device using the obtained power supply power. FIG. 2 is a cross-sectional view of a trolley conductor (cross-sectional view perpendicular to the axial direction), FIG. 3 is a perspective view of a trolley conductor cleaner, and FIG. 4 is a trolley conductor mounted on a trolley duct. Cross-sectional view of the cleaner (cross-sectional view perpendicular to the axial direction), FIG. 5 is a side view of the brush of the trolley conductor cleaner.

  As shown in FIG. 1, the trolley duct 1 is formed in a rectangular tube shape having a slit-shaped opening 1a below, and a plurality of (three in FIG. 1) trolley conductors are provided in the upper portion of the tube. 2 is extended. In FIG. 1, the trolley duct 1 is shown partially broken.

  The trolley 3 includes a current collector 4 corresponding to each trolley conductor 2 and a roller 16 that rolls on the bottom wall in the trolley duct 1, and the roller 16 while sliding the current collector 4 on the trolley conductor 2. Can be moved along the trolley duct 1. The electric power received by the current collector 4 from the trolley conductor 2 is supplied to an external device via a cable drawn out from the opening 1a.

  In the example of FIG. 1, a rail 7 having an I-shaped cross section is provided in parallel with the trolley duct 1, and a moving body 8 that moves along the rail 7 is provided. The movable body 8 is attached with a substantially U-shaped arm (arm) 6 that opens toward the trolley duct 1 via the bracket 9, and two distal ends of the arm 6 are connected to the trolley. 3 are respectively inserted into two rings 5 provided at both ends in the longitudinal direction, and the trolley 3 is pulled by the moving body 8. At this time, the power source for the moving mechanism such as a motor for moving the moving body 8 along the rail 7 may be supplied from the trolley 3 to the moving body 8 side, or supplied separately from other than the trolley 3. You may make it do.

  As shown in FIG. 2, the trolley conductor 2 is configured as a metal conductor such as copper or brass having an I-shaped cross section. The current collector 4 is in sliding contact with the lower end surface (sliding contact surface) 2a of the trolley conductor 2 while moving in the trolley duct 1 along its extending direction. In order to ensure more reliable conduction, it is pressed against the lower end surface 2a with an appropriate pressing force. Therefore, particularly when used for a long period of time, the lower protruding portion 2b of the trolley conductor 2 and the lower end surface 2a In the boundary portion 2c, burrs and whiskers (fibrous or spiny metal conductor lump) or the like due to plastic flow or the like may occur.

  Burrs, whiskers and the like generated in this way can be efficiently removed by the trolley conductor cleaner 10 according to the present embodiment. That is, as shown in FIG. 3, the trolley conductor cleaner 10 includes a main body portion 11 that is inserted into the trolley duct 1 and an arm 12 that is disposed outside the trolley duct 1. 12 is connected via a bracket 18 inserted through the slit-like opening 1a of the trolley duct 1.

  The trolley conductor cleaner 10 is moved along the extending direction of the trolley duct 1 by manual operation. That is, one end side of a chain, a rope, or the like is connected to the opening hole 19 provided in the arm 12, and the trolley conductor cleaner 10 is moved in the trolley duct 1 by pulling the other end side. The main body 11 is provided with a roller 16 that rolls on the bottom surface of the trolley duct 1 and a guide ring 17 that rotates about a vertically extending axis, so that the main body 11 can easily move in the trolley duct 1. It is like that.

  The main body 11 includes a brush 15 in which a plurality of hair bundles 20 extending directly upward are implanted on the upper surface of a substantially rectangular plate-shaped movable base 14.

  The bristles 20 are planted in a plurality of rows at intervals from each other in accordance with the number of the trolley conductors 2, and are further spaced apart at a plurality of locations along the extending direction of the trolley conductor 2 in each row. It is planted with a gap. In the example of FIG. 3, a total of 27 hair bundles 20, 9 bundles for each of the three trolley conductors 2, are arranged and planted on the movable base 14.

  The lengths of the hair bundles 20, that is, the heights from the upper surface of the movable base 14, are such that when the trolley conductor cleaner 10 is installed in the trolley duct 1, the tips of the hair bundles 20 are pushed against the lower end surface 2 a of the trolley conductor 2. The distance between the upper surface of the movable base 14 and the lower end surface 2a of the trolley conductor 2 is longer than the distance.

  Each hair bundle 20 is bundled in a long and narrow shape in the width direction of the trolley conductor 2 in plan view. As shown in FIG. 4, the width of the hair bundle 20 is made wider than the width of the trolley conductor 2. The front end portion is adapted to contact not only the lower end surface 2a but also the side surfaces of the boundary portion 2c and the lower overhang portion 2b.

  Moreover, it is suitable for the hair which makes the hair | bristle bundle 20 to be a fiber (for example, resin fiber) which has elasticity, and to be especially the resin fiber which bound metal powder. Thus, by giving elasticity to the hair, a bending reaction force or a buckling reaction force is generated in the hair (hair bundle 20) held between the movable base 14 and the trolley conductor 2, and the reaction force is The pressing force acts on the trolley conductor 2 from the hair bundle 20. Therefore, the pressing force by each hair bundle 20 increases as the length increases.

  And in this brush 15, the long hair area | region 15a in which the hair | bristle bundle | flux 20 with a long hair length was planted, and the short hair area | region 15b in which the hair | bristle bundle | flux 20 with short hair length were planted are connected to the trolley conductor 2. The section is arranged along the extending direction. As described above, since the pressing force increases as the length of the bristle increases, the brush 15 is provided with a plurality of regions with different pressing forces that are partitioned along the extending direction of the trolley conductor. It will be.

  Further, the brush 15 reciprocates (vibrates) along the extending direction of the trolley conductor 2. That is, a reciprocating drive mechanism (not shown) including, for example, a linear motor or the like is built in the base 13 at the center of the main body 11, and the movable base 14 in which the brush 15 is implanted by the reciprocating drive mechanism is connected to the trolley conductor 2. It is made to reciprocate (vibrate) along the extending direction. In addition, as a power supply of the reciprocating drive mechanism, a battery may be built in the main body unit 11 or may be supplied from the outside via a power harness (not shown).

  According to the above embodiment, the long hair region 15a in which the pressing force is increased and the short hair region 15b in which the pressing force is decreased are arranged in a partitioned manner, so that the length of the hair is uniformed as in the prior art. Compared with the case where the pressing force of the brush is increased, the progress of the wear of the trolley conductor 2 and the brush 15 can be slowed by suppressing the increase of the entire pressing force. Further, since the pressing force can be reduced, the sliding resistance (friction resistance) between the trolley conductor cleaner 10 and the trolley conductor 2 is reduced, and the trolley conductor cleaner 10 can be easily moved along the extending direction of the trolley conductor 2. There is also.

  Moreover, according to this embodiment, the removal capability of burrs, whiskers, etc. can be further enhanced by reciprocating (vibrating) the brush 15 in the front-rear direction along the extending direction of the trolley conductor 2. When the brush is rotated along the slidable contact surface of the trolley conductor 2, burrs, whiskers, etc. may be enlarged and the trolley conductors 2 and 2 adjacent to each other may be short-circuited. In this regard, in the present embodiment, it is possible to suppress the occurrence of such a problem by vibrating the brush 15 in the front-rear direction along the extending direction of the trolley conductor 2.

  Further, the step of the hair bundle 20 formed at the boundary between the long hair region 15a and the short hair region 15b increases the ability to remove burrs, whiskers and the like because the hair bundle 20 exhibits a side surface facing the reciprocating direction. For this reason, the configuration in which the long hair region 15a and the short hair region 15b are partitioned along the extending direction of the trolley conductor 2 as in the present embodiment is also advantageous in terms of the ability to remove burrs and whiskers.

  Moreover, according to this embodiment, the width | variety of the hair | bristle bundle 20 is made wider than the width | variety of the trolley conductor 2, and the front-end | tip part of the hair | bristle bundle 20 (brush 15) is not only the lower end surface 2a of the trolley conductor 2, but a boundary part. Since it reaches the side surface of the lower overhanging portion 2b beyond 2c, burrs, whiskers and the like generated at the boundary portion 2c can be more reliably removed.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, the shape and number of brushes and hair bundles, the arrangement, the width and arrangement of each region, and the like can be variously changed.

  FIG. 6 is a front view showing another example of a hair bundle. In this example, the bristles of the hair bundle 20A are cut into a V shape in front view (viewpoint from the extending direction of the trolley conductor 2), and the tip of the hair bundle 20A hits only the vicinity of the boundary portion 2c of the trolley conductor 2. It is what I did. By doing so, the sliding resistance between the trolley conductor 2 and the trolley conductor cleaner can be reduced, the degree of progress of wear can be slowed, and the life of these can be further extended.

  FIG. 7 is a front view showing still another example of the hair bundle. In this example, the hair bundle 20B is planted in a V shape in a front view so that the side surface of the tip of the hair bundle 20B only hits the vicinity of the boundary 2c of the trolley conductor 2. Also with such a configuration, the sliding resistance between the trolley conductor 2 and the trolley conductor cleaner can be reduced, the progress of wear can be slowed, and the life of these can be further increased.

  FIG. 8 is a front view showing still another example of the hair bundle. In this example, the hair bundle 20 </ b> C is implanted in an X shape in a front view so that the tip of the hair bundle 20 </ b> C hits only the vicinity of the boundary portion 2 c of the trolley conductor 2. Also with such a configuration, the sliding resistance between the trolley conductor 2 and the trolley conductor cleaner can be reduced, the progress of wear can be slowed, and the life of these can be further increased. In this case, the reaction force in the extending direction of the trolley conductor 2, that is, the traveling direction of the brush 15, is increased by the crossing of the left and right hair bundles, and the removal ability of burrs and whiskers can be further enhanced.

  FIG. 9 is a front view showing still another example of the hair bundle. In this example, similarly to the example of FIG. 6, the hair ends of the hair bundle 20D are cut into a V shape in front view so that the tip of the hair bundle 20D hits only the vicinity of the boundary portion 2c of the trolley conductor 2. At the same time, the hair constituting the hair bundle 20D is shortened to further reduce the sliding resistance and further improve the removal capability of burrs and whiskers.

  Moreover, as illustrated in FIG. 10 and FIG. 11, the arrangement of the long hair region 15a and the short hair region 15b can be appropriately changed. These brushes 15A and 15B can also enhance the ability to remove burrs, whiskers and the like because the step of the hair bundle 20 is formed at the boundary between the long hair region 15a and the short hair region 15b.

  FIG. 12 is a perspective view of a trolley conductor cleaner according to still another embodiment of the present invention. In this example, a ring 5 similar to the trolley 3 illustrated in FIG. 1 (that is, the movable body 8 shares the arm 6 for moving the trolley 3) is provided on the main body 11 </ b> A including the brush 15. The trolley conductor cleaner 10 </ b> A is moved by the moving body 8 by pulling the ring 5 by the arm 6 extending from the arm. According to such a configuration, there is an advantage that the labor of work can be saved because it is not necessary to move manually. However, in this case, it is preferable to separately supply power for driving the moving body 8 from other than the trolley 3.

  Moreover, each example mentioned above can be comprised combining suitably.
