Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cable-traction train running system, and more specifically, the present invention relates to a cable-traction train running system, and more specifically, on a track mainly consisting of a single-track track, with some double-track intersections and double-track stations. This relates to a train running system that runs back and forth by gripping a loop-shaped cable that is guided around a power pulley along a train.

(Prior Art) Conventionally, a system in which a traction cable is stretched around in a ring and a plurality of trains are run along the rails by pulling the traction cable is disclosed in Japanese Patent Publication No. 6028710, for example, in which a conveyor system for connecting vehicles to the traction cable is proposed. It is disclosed as a device.

According to the same publication, this device has three grips installed on the vehicle.
It consists of two cable gripping jaws, which grip the cable or hold the cable alternately, such as when the central jaw is closed, when both jaws are open, when the central jaw is open, and when both jaws are closed. The child grasps the rope and performs several movements.

The vehicle is towed by the central jaw in some sections, and by either jaw on either side in other sections.

(Problem to be Solved by the Invention) However, in the conventional device disclosed in the above-mentioned Japanese Patent Publication No. 60-28710, the cable is located below the track, and therefore the grip for gripping the cable and the guide sheave for guiding the cable are Both are located below the orbit. Therefore, not only is a three-dimensional space required, but most importantly, there is a support that connects the grip and the vehicle, so the track girder at the branch of the track is partially separated and moved, creating a gap and connecting the support. A branch track with a structure that passes through the area was required.

This has the problem of requiring a long operation time to move a large structure, shortening the interval between vehicle operations (which also has an adverse effect, and increasing construction costs).

Furthermore, since the position of the above-mentioned grip support is limited to a fixed position in the center of the track spacing, if a curved section is made into a single track, the positions of the traction cable and guide sheave for the outbound and return trips will overlap, making it difficult to route the cables. Therefore, curved sections had to be double tracked.

In view of the above-mentioned circumstances, the present invention aims to overcome these difficulties, and by finding a gripping method for the traction cable and the grip, it is possible to save the space for arranging the traction cable and the guide sheave, and to simplify the branch track structure. The purpose of this project is to convert curved sections into single tracks, realize long-distance transportation, increase transportation capacity, and reduce construction costs.

(Means for Solving the Problems) That is, a feature of the present invention is that a traction cable wrapped around a powered skid is stretched in a loop shape along both sides of the train running track, and the pulley is moved in one direction. In order to make the train run along the rails by pulling a rotating traction cable, each car is equipped with grips that protrude independently on the left and right sides, and on the outbound journey, one grip grips the cable on one side, while on the return journey, the train is moved along the rails. It is in a train running system that uses a grip in the opposite direction to grip the cable on the opposite side to perform round-trip travel.

Furthermore, the present invention transfers the loop-shaped traction cable of the above system from the upstream cable loop to the downstream cable by changing grips from the upstream cable to the downstream cable using the respective grips of trains stopped in parallel at intermediate stations in a crossed state. The purpose is to enable continuous operation to the side loop and to achieve the above-mentioned purpose.

Although the above running system can be applied to a single train, it is usually applied to a plurality of trains.

(Function) According to the above train running system, the grips protruding left and right from the vehicle correspond to the cables placed on both sides of the track, so when the power pulley rotates in a certain direction, for example, the left grip does not grab the cable. When the grip on the right side grabs the cable, it is on the return trip and the train is running.

Note that central intersections between stations and intermediate stations are usually double-track, and the rest operate as single-track, but even on single-track, traction cables are placed on both sides of the track, so you can grab either of them to track the outbound or return journey. (can be done) without hindering the progress of the process.

Additionally, at the terminal station, it is possible to make a return trip by simply changing the grip from left to right.

Furthermore, according to the invention as claimed in claim 2, since the upstream cable loop and the downstream cable loop are lined up in parallel at the intermediate station, the vehicle releases the upstream cable while stopping at the station and disconnects the downstream cable. By grasping the cable, so-called re-grabbing the cable, it becomes easy to continue the outward and return journey from the upstream loop to the downstream loop, realizing long-distance operation.

(Embodiments) Hereinafter, embodiments of the cable-traction train running system according to the present invention will be described in detail with further reference to the accompanying drawings.

FIG. 1 is a plan view of the entire cableway of the present system according to claim 1, in which (1) has a bulging intersection in the center and connects upstream and downstream station sections (2) and (2). Parallel guide rails (3), (3) ' have their both outer sides approximately parallel to the rails, and a power pulley (4) at one end;
A traction cable (hereinafter simply referred to as a cable) (6) is arranged in a loop around a driven pulley (5) at the other end.

(6)′ is the vehicle, (7) is the wheel, (8), (8)”
(9) is a grip attached to the left and right sides of the vehicle, and a branch guide wheel (9).

Note that, naturally, small-diameter guide sheaves are arranged at the bent portions of the cables, but their illustrations are omitted because the drawings would be too detailed.

Further, at the intersection, there is a branch guide rail 0ω along the guide rail (1), and a movable switch blade (11) as shown is attached to one end of the branch guide rail (1).
Vehicles (6), (6)' during round trip in cooperation with 9)
It is always possible to drive on the left (in the example shown).

This structure is a known structure used, for example, in the new transportation system of Osaka Nanko, Nietram, etc., and there are various other types, and these can also be used in the present invention.

On the cableway of the traveling system of the present invention configured as described above, one vehicle (6) grips the cable (3) with the grip (8) and runs from the downstream station (2)' to the upstream station (2). When it reaches and stops at the upstream station (2), the grip (8) opens and releases the cable (3), as shown in Figure 2, while the grip (8)' on the opposite side, which had been open until then, opens. , the cable (3)' is pushed in from below, and the cable (3)' is grasped.

Note that known means for gripping and releasing the cable by the grips (8) and (8)' are applied.

In this way, when passengers finish boarding and alighting at the upstream station (2) and a departure command is issued, the power pulley (4) starts rotating in the same direction again and the vehicle (6) departs toward the downstream station (2)'. . At the downstream station (2)', the same grip operation is performed simultaneously on the car (6)', and thus the two cars (6) and (6)' continue to travel back and forth. is repeated.

FIG. 3 is a plan view of the entire cableway system according to claim 2, to which the cableway shown in FIG. 1 is applied.

1st station A-A and 4th station G- located at both ends of this map
G and intersections B-B, D-D, and F-F all have the same structure and function as those described above, but the second station C-C1 in the middle
Since the structure and operation of the third station E-E are partially different, the following will mainly explain these points.

First, the system according to claim 2 is significantly different from the system according to claim 1 in that the former consists of one loop and only has upstream and downstream stations, whereas the latter system has only one loop and upstream and downstream stations. 1st station - 2nd station, 2nd station - 3rd station, 3rd station -
A cable loop is constructed for the 4th station and each section,
In addition, at these intermediate stations, the two loops on the upstream and downstream sides have parallel sections and overlap each other, making it possible to transfer trains between the two loops.

Since the structure 1 and function of the first station and the fourth station are exactly the same as those described above, the second station CC will be explained in detail next.

In Figure 3, vehicle 02)', θ is the second station C-C
Park parallel to it. In the illustrated example, there is a station in the middle of the vehicle, but there is no problem even if there is a station on both sides. In this case, the parallel guide rails connecting the two stations branch before and after the second station C-C to form a double track, and the upstream cables 05) and 05)' are also arranged along them, and the power pulley θω and two driven pulleys q'7) to form a loop. At the branching part of the guide rail 071), a branching guide rail is attached as in the example of FIG. 1, but since the drawing would be complicated, it is not shown here.

On the other hand, the downstream cables 08) and 08)' are similarly connected to a power pulley 09) and two driven pulleys Q along the guide rail of the double track section.
O2 further forms a loop around the two driven cars (21) at the third station.

In this way, the upstream cable loops 05) and θ9' and the downstream cables 08) and 08)' are sequentially interlocked in a chain, but if they are placed on a flat surface, there will be points where they intersect with each other. Therefore, as shown in Fig. 4, the upstream cable 05) and (+5)' driven pulley (
+7) section, and downstream cables 08), 08)'
The power pulley 09) and driven pulley 120 portion of the track base (2
2) It is installed by crawling under it. Also, power pulley 0
9) is provided with a motor (23) and a speed reducer (24).

Then, the upstream cable 0ω and the downstream cable θ8),
and upstream cable q5)' and downstream cable θ0
are arranged in parallel at close distances from each other, allowing the cable to be gripped and replaced by the grip described below.

Figure 5 shows a situation in which vehicle 02) entered from the second station, stopped at the first station, and is about to return to the second station and depart again.
Since the operation of ' is the same as in the example of FIG. 1, the explanation will be omitted.

Next, in Fig. 6, the vehicle 02' that entered the second station from the third station and stopped released the cable 08) from the grip (26) and instead grabbed the cable 0ω (in Fig. 3, the vehicle 02' stopped at the second station).・The vehicle heading towards the 1st station (indicated by the mark) is ready for departure, and the vehicle 03) on the opposite line enters and stops from the 1st station and connects the cable 0 from the grip (27)'.
5) Let go of C8)' and grab cable C8)' instead (also marked with * in Figure 3), indicating that you are about to leave for the third station.

FIG. 7 shows the situation in which the cable grip of the grip is changed in this case.

That is, immediately after arriving at the second station, the grip (26) opens, releases the cable 08), and then the cable 05) is pushed up into the grip opening and the grip (26) closes.

In addition, in some cases, grips (2
It is also possible to install two jaws in 6) and open and close them at the same time to change the grip on the cables q and θ8). In this case, there is a feature that the flow line for pushing up the cable 05) is not diagonal but parallel to the vertical direction.

Furthermore, the grip (
26) at the second station with parallel cables (151, (
Figure 9(a)
Grab the cable 08) in the stretched state as shown in Figure 9(b), come from the 3rd station to the 2nd station, release the cable 08) after the station stops, and then retract the grip (26) as shown in Figure 9(b). There is also a method of pushing the cable 05) up from below and pushing it into the opening of the grip (26).

This method has the advantage that the line of movement of the cable 01Q8) is not diagonal but parallel to the vertical direction, as described above.

The contents of the system of the present invention have been explained above, but
It goes without saying that the present invention is not limited to the above-mentioned aspects, and that modifications can be made in any other manner without departing from the scope of the claims.

Note that in the above explanation, there are several actions for pushing the cable up to the grip opening, and a specific example of this is shown in FIG. 1O. That is, (28) is a shoe with a groove on the top that has a curvature to receive the cable like a pulley;
(29) are hydraulic cylinders (hydraulic power source not shown) that support this and move it up and down, and two sets are provided on both sides with the grip (26) in the center. FIG. 10 shows the cable 05) lifted up and inserted into the opening of the grip (26). Since the shoe (28) has a groove with a large radius of curvature, it does not cause excessive bending to the cable. The present system is configured by combining such cable pushing devices.

However, the above-mentioned cable push-up device is just one example, and of course other structures may be used without any problem.

The cable re-gripping operation has been described above mainly at the second station, but the same applies to the third station. In this way, six trains can travel up and down the entire line shown in FIG. 3 without any hindrance while changing the cables. In this case, although Fig. 3 shows the situation up to the fourth station, it is possible to extend the chain to the fifth and sixth stations by increasing the number of cable loops that mesh with the chain.

It is also possible to eliminate the terminal stations at both ends and deploy cable loops on the ring, eliminating turn-around operations and allowing trains to go around.

Furthermore, although the curved section is not particularly shown in the drawings, it is clear that no trouble will occur because the cables are arranged on both sides of the guide rail and do not cross or overlap each other.

(Effects of the Invention) As described above, the present invention provides grips that protrude on the left and right sides of the train, and on the outbound journey, one grip handles the cable on one side, while on the return journey, the grip on the other side handles the cable on the opposite side. It is based on a system that allows the user to grab and move back and forth, and has the following effects.

(1) It is no longer necessary to arrange a traction cable and guide sheave under the track, which saves space compared to the one described in Japanese Patent Publication No. 60-28710, and the structure of the track is simplified, reducing construction costs. Become cheap.

(2) Branching girders are not required, and branching guide rails that have a simple structure and short operation time are only required to be installed on the track bed, and therefore, the vehicle travel time interval can be shortened. Furthermore, the structure of the track branch becomes extremely simple and construction costs are reduced.

(3) Although the conventional grip described in Japanese Patent Publication No. 60-28710 required the curved portion to be made into a double track, the grip of the present invention can be made sufficiently with a single track, and the track construction cost is significantly reduced.

(4) Furthermore, in the invention described in claim 2, the traction cable of one section L loop is partially folded at intermediate stations to connect several positions in a chain, and the cable is repeatedly gripped and replaced by the grip. This has the advantage of allowing the transportation distance to be extended at will.

(5) Also, since two trains can be arranged for each loop (one section) of the traction cable, as many trains as (2 x number of sections) can be inserted into a line of several meters apart, and transportation Capabilities can be dramatically increased.
