  2. Description of the Related Art As shown in Japanese Utility Model Publication No. 7-22965 (Patent Document 1), an insulated trolley wire current collector that supplies electricity to a moving load such as a hoist or a conveyor is known. This insulated trolley wire current collector is composed mainly of an insulated trolley wire attached to a construction material such as a ceiling and a current collector attached to a moving load, and the current collector is in sliding contact with a conductor of the insulated trolley wire, Electricity is supplied from a conductor to a load that moves via a current collector. The current collector includes a current collector piece that is in sliding contact with the insulated trolley wire, a current collector side rotary seat that receives a shaft provided on the current collector piece, a load side rotary seat that receives a shaft provided on a load, and both ends of the current collector Arms are rotatably connected to the current collector side rotary seat and the load side rotary seat.

  This current collector is in sliding contact with the insulated trolley wire while following the moving addition, but the current collecting path does not coincide with the arrangement path of the insulated trolley wire, so the current collector does not deviate from the insulated trolley wire. Thus, it is set as the above structures so that a position and direction may become movable with respect to the moving load.

  The insulated trolley wire is arranged along the movement path of the moving load, but due to various restrictions, it may be composed of a plurality of insulated trolley wires that are divided in some places instead of one continuous insulated trolley wire. Generally done well. In this case, the current collector needs to move between the plurality of separated insulated trolley wires to be in sliding contact.

  The insulating trolley wire is configured by arranging a conductor at the bottom of a groove formed in the insulating frame, and the inner wall of the groove serves as a guide for the current collecting piece. When the current collector is transferred from one insulated trolley wire to another separated insulated trolley wire, the current collector piece needs to be accommodated in the groove of the insulated trolley wire to which the current collector piece is transferred. As described above, the position and angle with respect to the load are movable within a certain range, and cannot be reliably and stably accommodated in the groove of the insulated trolley wire to which the current collector piece is transferred. It was.

Therefore, as shown in Japanese Utility Model Laid-Open No. 5-93962 (Patent Document 2), there is devised one in which a laterally extending guide is provided at the end of the insulated trolley wire.

  However, in the above conventional example, when the current collector is transferred from one insulated trolley wire to another insulated trolley wire, the current collector piece collides with the inner wall of the groove of the insulated trolley wire, and the current collector Electrons are impacted, and a load is particularly applied to the connecting portion between the rotary seat and the arm, and stress concentration occurs at the tip of the current collector piece due to collision with the insulated trolley wire. From this, in order to ensure the lifetime of the apparatus, it was necessary to suppress the traveling speed of the current collector.

  The present invention was invented in view of the above-described background art, and its purpose is to reduce the impact on the current collector when the current collector is transferred from the insulated trolley wire to another insulated trolley wire. It is an object of the present invention to provide an insulated trolley wire current collector capable of extending the life of the battery and increasing the traveling speed of the current collector.

In order to solve the above-described problem, in the invention according to claim 1 of the present application, an insulated trolley wire collector that supplies electricity to the load by bringing a current collector attached to a moving load into sliding contact with an insulated trolley wire attached to a construction material. The current collector includes a current collecting piece that is in sliding contact with the insulated trolley wire, and a plurality of insulated trolley wires are arranged in the longitudinal direction, and the current collecting piece is guided to the insulated trolley wire at each end. The guide groove has an inclination angle with respect to the traveling direction of the current collector , and the inclination angle decreases in a plurality from the proximal end portion to the distal end portion of the induction groove.

The guiding groove is characterized in that a plurality of guiding grooves provided side by side form a concave portion having a substantially arcuate cross section extending from the distal end portion to the proximal end portion of the guiding groove .

In the insulated trolley wire current collector according to claim 1 of the present application, the insulating trolley wire has a pickup guide having a guiding groove for guiding the current collecting piece to the insulating trolley wire at the end of the insulating trolley wire, and the guiding groove is a collector current collector. Since it is inclined with respect to the traveling direction , the current collector can be stably and steadily accommodated in the insulated trolley wire, and the inclination angle of the guiding groove with respect to the traveling direction of the collecting current is from the base end of the guiding groove. Since it has multiple values that decrease toward the tip, the angle of inclination near the tip of the guide groove where the current collector collides first is small, so the impact caused by the collision of the current collector with the guide groove is reduced. can do. As a result, the load on the connecting portion between the rotary seat and the arm can be reduced, so that the life of the apparatus can be extended and the traveling speed of the current collector can be increased.

In insulated trolley wire current collector of the invention according to claim 2 is provided with a pick-up guide having a guiding groove for guiding the current collector pieces in the insulating trolley wire in the end portion of the insulating trolley wire, further guiding grooves of the current collector Since it is inclined with respect to the traveling direction , the current collector can be stably and steadily accommodated in the insulated trolley wire, and a plurality of guiding grooves are arranged in a longitudinal direction from the leading end to the proximal end of the guiding grooves. Since the surface forms a substantially arc-shaped recess, the angle of inclination with respect to the direction of current collection near the tip of the lead-in groove where the current collector collides first is small, so Impact can be mitigated. As a result, the load on each part of the current collector can be reduced, so that the life of the apparatus can be extended and the traveling speed of the current collector can be increased. Furthermore, since the inclination angle of the attracting groove with respect to the direction of current collection continues to gradually increase, when the current collector slides on the attracting groove, the operation of each part of the current collecting is moderated. be able to.

Therefore, by providing the centering member 8 as in the present embodiment, the orientation of the current collecting piece 11 is maintained by the restoring force of the centering member 8.

  FIG. 11 shows a state when the current collector 1 is transferred to the insulated trolley wire 2. When the current collector 1 is transferred to the insulated trolley wire 2, the current collecting piece 11 collides with the vicinity of the tip end portion 28bb of the lead-in groove 28b. Therefore, the inclination angle θ2 of the guiding groove 28b in the vicinity of the tip end portion 28bb can be configured to be small. As a result, the impact caused by the collision of the current collector 1 with the guiding groove 28b can be reduced. Thereafter, the current collector 1 travels in the traveling direction, and the upper surface of the current collector piece 11 comes into sliding contact with the guide groove 28b. Further, as the inclination angle θ changes (from θ2 to θ1), the current collector piece casing 10 rotates counterclockwise around the pivot 13 and the current collector piece 11 slides in the guide groove 28b. Go. Further, the current collecting piece 11 is guided to the groove 22 of the insulating trolley wire 2 by the guide groove 28a, the current collecting piece casing 10 is rotated clockwise around the pivot 13 and the current collecting 1 is turned into the insulating trolley.

Can be stably and steadily accommodated in the insulated trolley wire 2, and the inclination angle θ of the guide groove 28b with respect to the horizontal plane has a plurality of values that decrease from the base end portion 28ba to the tip end portion 28bb of the guide groove 28b. Therefore, since the inclination angle θ in the vicinity of the leading end portion 28bb of the guiding groove 28b with which the current collector 1 collides first is small, the impact caused by the collision of the current collector 1 with the guiding groove 28b can be reduced. As a result, the load on the connecting portion between the rotary seats 3 and 4 and the arm 5 can be reduced, so that the life of the apparatus can be extended and the traveling speed of the current collector 1 can be increased.

  Next, an insulated trolley wire current collector that is a second embodiment of the present invention will be described. Here, only matters different from those in the first embodiment will be described, and other matters (configuration, operational effects, and the like) are the same as those in the first embodiment, and thus description thereof will be omitted.

A plurality of the insulating trolley wires 2 are arranged in the longitudinal direction, and the current collecting pieces 11 are guided to the insulating trolley wire 2 at each end. A pickup guide 27 having a guide groove 28b is provided, and the guide groove 28b forms a recess having a substantially arc-shaped longitudinal section across the width direction ( from the leading end portion to the proximal end portion of the guiding grooves provided in a plurality of rows ).

  When the current collector 1 is transferred to the insulating trolley wire 2, the current collector piece 11 collides with the vicinity of the tip end portion 28bb of the guiding groove 28b. The guiding groove 28b forms a concave portion having a substantially arc-shaped longitudinal section in the width direction. Thus, the inclination angle θ with respect to the horizontal plane of the guide groove 28b in the vicinity of the tip end portion 28bb is configured to be small. As a result, the impact caused by the collision of the current collector 1 with the guiding groove 28b can be reduced. Thereafter, the current collector 1 travels in the traveling direction, and the upper surface of the current collector piece 11 comes into sliding contact with the guide groove 28b. Further, as the inclination angle θ increases as it goes to the base end portion 28ba, the current collecting piece 11 slides in the guiding groove 28b while the current collecting piece casing 10 rotates counterclockwise around the pivot portion 13. I will do it. Further, the current collecting piece 11 is guided to the groove 22 of the insulating trolley wire 2 by the guide groove 28a, the current collecting piece casing 10 is rotated clockwise around the pivot 13 and the current collecting 1 is turned into the insulating trolley. Housed in line 2.

  Accordingly, a pickup guide 27 having a guiding groove 28b for guiding the current collecting piece 11 to the insulating trolley wire 2 is provided at the end of the insulating trolley wire 2, and the guiding groove is inclined with respect to the horizontal plane. Can be stably and steadily accommodated in the insulating trolley wire 2, and the guiding groove 28b forms a concave portion having a substantially arc-shaped longitudinal section in the width direction. Since the inclination angle θ with respect to the horizontal plane in the vicinity of the front end portion 28bb of 28b is small, the impact caused by the collision of the current collector 1 with the guiding groove 28b can be reduced. As a result, the load on the connecting portion between the rotary seats 3 and 4 and the arm 5 can be reduced, so that the life of the apparatus can be extended and the traveling speed of the current collector 1 can be increased. Further, since the inclination angle θ of the guide groove 28b with respect to the horizontal plane continuously increases gradually, when the current collector 1 slides on the guide groove 28b, the connecting portion of the rotary seats 3, 4 and the arm 5 is connected. The operation can be made gradual. This can also reduce the load on the connecting portion between the rotary seats 3 and 4 and the arm 5, thereby extending the life of the apparatus and increasing the traveling speed of the current collector 1.
