It is an object of the present invention to provide a trolley-powered carriage traveling device that can be safely performed and can supply trolley power without requiring a large space.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-mentioned problems, the present invention is conceived by arranging an auxiliary power supply vehicle that performs trolley power supply while being accompanied by a carriage along the width direction of a road portion intersecting with a rail. It was made.
That is, a first trolley-fed trolley travel device according to the present invention (Claim 1) includes a transport trolley traveling on a rail and having a current collector, and a crossing along the longitudinal direction of the rail and intersecting the rail. A plurality of power supply trolleys arranged across a road and in contact with the current collector of the transport carriage, and an auxiliary power supply trolley that can travel between the power supply trolleys and can contact the current collector of the transport truck And an auxiliary power supply vehicle having the following.

  According to this, when the transport cart that has traveled with the current collector contacting one of the plurality of power feed trolleys reaches the intersection, the current collector is supported by the auxiliary power feed vehicle. With the contact with the power supply trolley and maintaining such contact, the transport cart and the auxiliary power supply vehicle travel across the intersection while being synchronized. Almost simultaneously with approaching the other power supply trolley, the current collector of the transport carriage contacts the other power supply trolley and moves away from the auxiliary power supply trolley of the auxiliary power supply vehicle. Therefore, even if there is a crossing road such as a road that crosses the rail at right angles or obliquely in the middle of the rail, the trolley-fed transport cart can be reliably driven, and maintenance can be easily and safely performed. In order to run the auxiliary power supply vehicle, it is possible to use less space.

In addition, although the current collection part of the said conveyance trolley may be one place, the form attached to two places near the front end and the rear end in the traveling direction of the said conveyance trolley is desirable.
Further, the width of the intersection is larger than the length along the traveling direction of the transport carriage.
Further, the intersection includes a road, a railroad track, a sidewalk, a car sidewalk and the like.
The plurality of power supply trolleys and the auxiliary power supply trolleys of the auxiliary power supply vehicles may be at least one trolley wire if the drive source of the transport carriage is a DC motor. In order to supply power together with other wiring circuits, a plurality of trolley wires may be installed in parallel in the vertical direction as will be described later.
Further, when a wide crossing road or two or more crossing roads cross in the longitudinal direction of the rail, for example, a wide crossing road or a plurality of auxiliary feedings having the auxiliary power supply trolley for every two crossing roads. In addition to arranging a train, one auxiliary power supply vehicle may be arranged so as to be able to travel on the auxiliary rail along the entire length of the wide intersection or two intersections and the rail portion sandwiched between them.
In addition to the form of supplying power to the motor, which is the drive source of the auxiliary power supply vehicle, via a take-up reel type cable that can be wound and wound from one of the plurality of power supply trolleys, Electric power may be supplied from a battery mounted on the train.

Further, according to the present invention, the auxiliary power supply vehicle can travel along an auxiliary rail or a guide groove parallel to the rail, or can travel along an electrical or magnetic guide parallel to the rail. The trolley feeding type cart traveling device (Claim 2) is also included.
According to this, it is possible to reliably supply power to the current collector of the transport carriage while traveling along the width direction of the intersection road along with the transport carriage that has reached the intersection. It becomes possible. The above-mentioned electric / magnetic guide includes an electric / magnetic sensor attached to the auxiliary power supply vehicle and a magnet using a metal strip with a flat surface that forms an electric field or a magnetic field in a non-contact manner. For example, the power supply vehicle may be driven by a rubber tire or a rubber crawler.

  On the other hand, a second trolley-fed trolley travel device according to the present invention (Claim 3) includes a transport trolley traveling on a rail and having a current collector, and an intersection along the longitudinal direction of the rail and intersecting the rail. Provided on at least one of the plurality of power supply trolleys arranged across the road and in contact with the current collector of the transport carriage, and on the other power supply trolley while contacting the one power supply trolley And an auxiliary power supply body having an auxiliary power supply trolley capable of moving forward and backward.

According to this, almost simultaneously with the conveyance carriage approaching the crossing road, the current collector part cancels the contact with one of the plurality of power supply trolleys and contacts the auxiliary power supply trolley of the auxiliary power supply body that can advance and retreat. . For this reason, the transport carriage crosses the crossing along the width direction while receiving power supply from the auxiliary power supply trolley of the auxiliary power supply that moves forward and backward in synchronization, and then makes the current collector contact the other power supply trolley. be able to. Therefore, even if there is an intersection on the rail, the trolley-powered transport carriage can be reliably driven, maintenance can be performed easily and safely, and the space for moving the auxiliary power supply forward and backward (forward and backward) is further reduced. It becomes possible to do.
The auxiliary power supply body having the auxiliary power supply trolley is arranged in parallel directly above or immediately below the trolley wires of the plurality of power supply trolleys, for example, a motor that receives power supply from any of the power supply trolleys, and a plurality of stages of telescopic booms Alternatively, it can be moved back and forth along the longitudinal direction of the rail and the width direction of the crossing path by a piston / cylinder mechanism.

Further, according to the present invention, each of the plurality of power supply trolleys has a plurality of trolley wires installed in parallel vertically, and the auxiliary power supply vehicle or the auxiliary power supply body has the same number of trolleys as above and below. Also included is a trolley-powered carriage traveling device (Claim 4) having the auxiliary power-feeding trolley laid in parallel on the side surface.
According to this, when the drive source of the transport carriage is an AC motor, or when a wiring circuit for control or braking is provided, a feeding trolley in which a required number of trolley wires are installed in parallel up and down, Auxiliary power supply trolleys arranged along the side of the rail and having the same number of trolley wires installed in parallel are provided on the side surface of the auxiliary power supply vehicle or the side surface of the auxiliary power supply body. Thus, the auxiliary power supply vehicle or the auxiliary power supply body can be run or moved back and forth (slid) while being accompanied by the transport carriage.

Here, the effect | action of the 1st trolley electric power feeding type trolley | bogie traveling apparatus S is demonstrated.
As shown in FIG. 6, the auxiliary power supply vehicle 10 is waiting in advance in a standby space 18 at the left end of the auxiliary rail r. First, as shown by the arrow in FIG. 6, the transport cart 1 that has traveled to the right while being fed from the power feeding trolley Ta on the left side via the current collectors 5a and 5b is assisted immediately before the road (intersection) C. When reaching the side of the power supply vehicle 10, the shoes of the current collectors 5 a and 5 b are sequentially separated from the trolley lines of the power supply trolley Ta and sequentially to the trolley lines of the auxiliary power supply trolley t of the auxiliary power supply vehicle 10. Contact. Immediately before this state is reached, for example, it is detected that the transport carriage 1 has approached the road C by a relay or a position sensor using a phototube, and the circuit breaker s is closed and the motor 16 of the auxiliary power supply vehicle 10 is turned on. It is activated.

In such a state, the electric power supplied from the cable 15 drives the motor 16 of the auxiliary power supply vehicle 10 and passes through the shoes of the current collectors 5a and 5b that are in contact with the trolley wires of the auxiliary power supply trolley t. The motor of the transport carriage 1 is also supplied with power. At this time, the motor 16 of the auxiliary power supply vehicle 10 and the motor of the conveyance carriage 1 are controlled synchronously or controlled so that the traveling speeds of the conveyance carriage 1 and the auxiliary electric supply vehicle 10 coincide.
As a result, as shown by the arrows in FIG. 7, the transport carriage 1 and the auxiliary power supply vehicle 10 maintain the contact state between the trolley wires of the auxiliary power supply trolley t and the shoes of the current collectors 5a and 5b, The vehicle travels adjacently on the rail R and the auxiliary rail r along the width W direction of C.
Next, as shown in FIG. 8, when the auxiliary power supply vehicle 10 approaches the right end side of the auxiliary rail r, the motor 16 is stopped by the position sensor, the limit switch, or the like, and the auxiliary power supply vehicle 10 stops at the position.

The trolley wires are sequentially separated from the trolley wires and sequentially contact the trolley wires of the feeding trolley Tb.
During this period, at least one of the current collectors 5a and 5b is always in contact with one of the power supply trolley Ta, the auxiliary power supply trolley t of the auxiliary power supply vehicle 10, and the power supply trolley Tb. This makes it possible to run smoothly.
Then, as indicated by the solid line arrow in FIG. 9, when the transport carriage 1 crosses the road C to the right side, the auxiliary power supply vehicle 10 supplies power from the cable 15 by the relay or the like almost simultaneously. While receiving, the motor 16 is reversely rotated. As a result, as indicated by the broken-line arrow in FIG. 9, the auxiliary power supply vehicle 10 travels on the auxiliary rail r across the road C to the left and winds the cable 15 around the cable reel 13 while waiting. Return to 18 and stop. When the return of the auxiliary power supply vehicle 10 is confirmed by the relay or the like, the breaker s is opened and the vehicle can pass through the road C.

  According to the trolley-fed trolley travel device S as described above, when the transport trolley 1 that has traveled while the current collectors 5a and 5b are in contact with one power-feed trolley Ta approaches the road (intersection) C. At substantially the same time, the current collectors 5a and 5b are separated from the power supply trolley Ta and in contact with the auxiliary power supply trolley t of the auxiliary power supply vehicle 10 in this order. Travel across road C in sync. Then, almost simultaneously with the approach to the other power supply trolley Tb, the current collectors 5a and 5b of the transport carriage 1 are separated from the auxiliary power supply trolley t of the auxiliary power supply vehicle 10 and sequentially contact the other power supply trolley Tb. . Therefore, even if there is an intersecting road such as the road C that intersects the middle of the rail R, the transport carriage 1 using the trolley power feeding system from the side of the rail R can be reliably run. In addition, maintenance can be performed easily and safely, and the auxiliary power supply vehicle 10 can be traveled with less space.

FIGS. 10-12 is a top view which shows the outline of the trolley electric power feeding type trolley | bogie traveling apparatus S1 which is an application form of the said traveling apparatus S. FIG.
As shown in FIG. 10, the trolley-powered carriage travel device S1 is slightly separated from the transport carriage 1 traveling on the rail R and the road (intersection) C that intersects the rail R at a right angle, as described above. A pair of feeding trolleys Ta and Tb arranged in a row and an auxiliary feeding that can travel about half the width W of the road C between the feeding trolleys Ta and Tb and that can contact the current collecting portions 5a and 5b of the transport carriage 1 And a pair of auxiliary power supply vehicles 10a and 10b having a trolley t. The pair of auxiliary power supply vehicles 10a and 10b run on the auxiliary rail r laid in parallel to the side of the rail R including the road C, and when the breaker s is in an open state, the standby electric vehicles 10a and 10b are on standby at both ends of the auxiliary rail r.

At about the same time, the current collectors 5a and 5b are sequentially separated from the power supply trolley Ta and sequentially contact the auxiliary trolley t of the auxiliary power supply vehicle 10a. Immediately before entering this state, it is detected that the transport carriage 1 has approached the road C, the circuit breaker s is closed, and the motor 16 of the auxiliary power supply vehicle 10a is started.

In such a state, the electric power supplied from the cable 15 drives the motor 16 of the auxiliary power supply vehicle 10a and also to the motor of the transport carriage 1 via the current collectors 5a and 5b contacting the auxiliary trolley t. Power is supplied. At this time, the motor 16 of the auxiliary power supply vehicle 10a and the motor of the transport carriage 1 are controlled synchronously, or are controlled so that the traveling speeds of the transport carriage 1 and the auxiliary power supply vehicle 10 coincide.
As a result, as indicated by the arrows in FIG. 11, the transport carriage 1 and the auxiliary power supply vehicle 10a are in contact with the auxiliary trolley t and the current collectors 5a and 5b along the width W direction of the road C. The vehicle travels adjacently on the rail R and the auxiliary rail r.

The cable 15 wound around the cable reel 13 of the auxiliary power supply vehicle 10b is connected to the power supply trolley Tb. As a result, the current collectors 5a and 5b of the transport carriage 1 traveling on the right side are sequentially separated from the auxiliary power supply trolley t of the auxiliary power supply vehicle 10a and sequentially contact the auxiliary power supply trolley t of the auxiliary power supply vehicle 10b. Thereafter, after the carriage 1 travels in synchronization with the auxiliary power supply vehicle 10b and crosses the road C, the current collectors 5a and 5b sequentially move away from the auxiliary power supply trolley t of the auxiliary power supply vehicle 10b, and then the other Of the power supply trolley Tb in order and travel on the rail R toward the right side.

Then, after the transport carriage 1 has crossed the road C, the auxiliary power supply vehicles 10a and 10b are rotated reversely one after another while receiving power from the cable 15 by, for example, a relay. . As a result, as indicated by the dashed arrow in FIG. 12, the auxiliary power supply vehicle 10 a travels to the left across the road C and returns to the standby space 18 while winding the cable 15 around the cable reel 13. Stop. A little later, the auxiliary power supply vehicle 10b returns to the right standby space 19 and stops in the same manner. When the return of the auxiliary power supply vehicles 10a and 10b is confirmed by the relay or the like, the circuit breaker s is opened and the vehicle can pass through the road C.
According to the trolley-fed trolley travel device S1 as described above, in addition to the effect of the travel device S, the width W of the road C intersecting with the rail R is large, or the two roads C intersect with the rail R. Even when a place or a road and a railroad that are substantially parallel to each other intersect at the same portion of the rail R, it can be easily installed.

FIG. 13 is a plan view showing an outline of a second trolley-fed trolley travel device S2 according to the present invention. That is, as shown in FIG. 13, the trolley-fed trolley travel device S2 sandwiches the same transport trolley 1 traveling on the rail R and the road (intersection) C intersecting the rail R at a right angle.
