Description

Hybrid transportation system {HYBRID TRANSPORT SYSTEM}

The present invention relates to a hybrid transportation system, and more particularly, to a hybrid transportation system capable of operating a vehicle in parallel with a road surface and a track.

Urban transport systems are based on roads, railroads, subways, and monorails. Subway and monorail systems have been the preferred means of public transportation to solve urban traffic congestion and environmental problems. The monorail system is a railway that operates a vehicle by a single track, and has a construction cost lower than that of a subway, and can reduce the occupied area by using a road or a river, and has a low noise and vibration pollution. The monorail system is divided into a suspended type in which a vehicle is suspended on a track and a straddled type in which a vehicle is driven on a track. The oversized monorail maintains the vehicle's equilibrium by guide wheels.

In a monorail system, a pair of drive wheels of a vehicle are made of rubber wheels and run along a planar top surface of a guide rail. A pair of guide wheels of the vehicle guides the vehicle while rolling contact.

Since the oversized monorail system has a narrow width of the driving wheels and a large amount of shaking in the left and right directions, the guide wheels are disposed below the running surface. Accordingly, the monorail vehicle has a disadvantage in that a structure for guiding a vehicle to be moved to any place such as a garage and a garage is required, which requires a lot of construction cost.

In addition, the vehicle used in the monorail system has the driving wheels arranged close to the lower center of the vehicle, and the guide wheels are disposed below the driving wheels to reduce the construction cost by eliminating the induction structure necessary for the movement of the vehicle. There is a need to develop a system that can move on a general road or garage without a guide structure. On the other hand, since the monorail system has a lot of sections installed on the bridge, a way to safely evacuate the passengers from the track in case of an accident such as a vehicle breakdown should be prepared.

The present invention has been made to solve the various problems described above, an object of the present invention is to provide a hybrid transport system that can safely drive in parallel with the road surface and track.

Another object of the present invention is to provide a hybrid transportation system in which the guide wheels can improve stability by an inner surface contact structure in which the guide wheels are in contact with both inner surfaces of the guide rail.

Still another object of the present invention is to provide a hybrid transportation system that can secure an emergency escape route in the center of the guide rail.

Still another object of the present invention is to provide a hybrid transportation system that can be easily installed on the bridge and tunnel.

Still another object of the present invention is to provide a hybrid transportation system that can be constructed at a construction site by preparing a guide rail, a bridge, and a tunnel in advance.

A feature of the present invention for achieving these objects is a pair of drive wheels connected by axles to be disposed on both sides of the bogie, and a pair of drive wheels. A coupling device that connects the guide wheels to the axle to store the guide wheels and a pair of guide wheels between the pair of drive wheels, and is mounted to the coupling device for receiving power. A vehicle having a current collector; To form a track for driving the vehicle, a pair of guide wheels, a coupling device and a current collector are installed at intervals so as to enter, and the upper surface is formed as a running surface so that the pair of driving wheels are in contact with the clouds. A pair of guide rails having inner surfaces facing each other such that the pair of guide wheels are in rolling contact with each other, and having a plurality of holes formed in the inner surface at intervals along the length direction; A plurality of insulators mounted in the plurality of holes to supply power to the current collector, and a pair of power supply lines wired to the plurality of insulators to supply power to the current collector, and the plurality of insulators The horizontal center axis of two adjacent insulators has a height difference, and a pair of power supply lines are in a hybrid transportation system including a feeder that is wired diagonally between two insulators.

In the hybrid transportation system according to the present invention, the guide wheels and the current collector are stored between the driving wheels by the operation of the coupling device, so that the road and the track can be safely driven in parallel, and various vehicles such as light rail, articulated bus, and bus. Can be adopted. The guide wheels can improve the stability by the inner surface contact structure of the rolling contact with the inner surface of the both sides of the guide rail, by securing an emergency escape route in the center of the guide rail, passengers can be evacuated safely in bridges and tunnels. In addition, since guide rails, bridges, and tunnels can be manufactured in advance and can be easily and quickly installed at the construction site, the construction cost can be reduced, and the construction period can be shortened.

The support bars 92 may be configured as steps formed integrally under the inner surface of the guide rails 70 so as to support both ends of the gratings 94.

As shown in FIG. 2 and FIG. 10, a pair of hooks 96 are rotatably mounted on both sides of the trolley 20. When the hooks 96 are caught by the jaws 84 of the guide rails 70, the vehicle 10 may not fall to the left and right of the guide rail 70, thereby preventing the vehicle 10 from tipping over.

6 to 10, the hybrid transportation system according to the present invention includes a power feeding device 100 installed along the guide rails 70 to supply power to the current collector 50. The power supply device 100 is composed of a plurality of insulators 102 and a pair of power supply lines 104. The insulators 102 are mounted in the holes 82 for insulation. The power supply lines 104 are suspended from the insulators 102 and are in contact with the current collecting shoes 68 to supply power to the current collector 50.

A plurality of spacers 106 are mounted between the inner surface of the holes 82 and the outer surface of the insulators 102 so that the center of the insulators 102 is adjusted with respect to the center of the holes 82. Two adjacent insulators 102 of the plurality of insulators 102 are shifted so that their horizontal center axes 102a have a height difference by adjustment of the center. Therefore, the power supply lines 104 hanging on the two insulators 102 are arranged diagonally, and the lifespan due to wear of the current collector shoes 68 is changed while the contact surfaces of the current collector shoes 68 contacting the power supply lines 104 are changed. Shortening is prevented.

Both ends of the top plates 114 are supported by the coping 112c by a plurality of pedestals 118. Side openings 114a for drainage are formed along the longitudinal direction in the center of the upper plates 114. Since drainage such as rainwater is made smoothly through the side opening 114a, it is not necessary to separately install the drainage pipe on the bridge 110.

The support posts 116 are erected on the upper surface of the top plate 114 to support the guide rails 70. The support posts 116 are composed of pipes 116a. The abdominal structure of the pipe 116a may reduce the weight of the bridge 110 to improve economical construction and reduce construction cost. Wiring holes 120 for wiring through the cable 120a and pipes are mounted on the outer surfaces of the support posts 116. In the present embodiment, the guide rails 70 may be directly installed on the upper surfaces of the upper plates 114 as necessary. On the other hand, except for the foundation 114a, the pier 112, the top plate 114 and the support posts 116 like the guide rails 70 before the construction of the bridge 110 before the construction site after construction in advance Since the construction can be transported to the site, the management of the construction site is easy and the workability can be improved. In addition, the gratings 94 are mounted between the guide rails 70 to form an emergency escape route, and the abdominal structure of the support posts 116 minimizes the blocking of sunlight to show a high density of population and buildings in the city section.
