Description

[Technical field]

[0001] The present invention relates to a ropeway carriage, and more particularly to a ropeway carriage equipped with a battery and control equipment for supplying power to an air conditioning device or the like. [Background technology]

[0002] A cableway is a transportation facility that suspends a carrier from a cable stretched in the air to transport people and goods, and is often used as a means of transporting people on mountain slopes and for skiers and snowboarders at ski resorts. In addition, cableways do not require rails to be laid on the ground like railways, and therefore require less land for the tracks, and therefore are increasingly being used as a form of public transport in urban areas, especially overseas.

[0003] Thus, when operating cableway facilities that operate closed carriages such as gondola lifts and ropeways in urban areas, it is desirable to provide the same level of convenience and comfort as other urban transport systems, and it is particularly desirable to provide each carriage with an air conditioning unit to improve passenger comfort. However, as has been well known in the past, in cableway facilities, it is difficult to supply power to carriages moving along the tracks, and it is difficult to provide each carriage with an air conditioning unit that consumes a large amount of power.

[0004] For this reason, the following techniques have been proposed and implemented in the past. One example of this technique is to form a carriage group consisting of a plurality of carriages, and to provide a plurality of such carriage groups so that the train travels with the circulating movement of a cable. One carriage in the carriage group is a power carriage equipped with a power supply device, and the other carriages are passenger carriages on which passengers board. Each passenger carriage is equipped with an air conditioning device, and power is supplied from the power carriage to each passenger carriage via a power supply cable, so that the passenger carriage is air-conditioned (see, for example, Patent Document 1). Another example is to form an equipment space separated from the passenger space above the passenger car, and provide a gas turbine engine and a generator, and an air conditioning device driven by the engine and generator, to air-condition the passenger space (see, for example, Patent Document 2).

[0006] Recently, the development of batteries has progressed rapidly, and batteries with large capacity and rapid charging are being supplied. For this reason, in cableways, batteries are installed on the carriages, and while the carriages are being sent around the station, power is supplied to the batteries to perform rapid charging, and it has become possible to continuously drive air conditioners on the cableway line using the power supply from the batteries. In this way, when driving air conditioners with batteries, it is necessary to provide a converter or inverter for converting the voltage, and when installing these converters or inverters, it is necessary to consider waterproofing measures and heat dissipation of the converter or inverter.

[0007] The present invention has been made in consideration of the above circumstances, and aims to provide an air-conditioned cableway carrier that, when the carrier's air conditioning unit is driven by power supplied from a battery, does not require special waterproofing measures for the converter or inverter that converts power from the battery, and can be installed in a way that allows the converter or inverter to be cooled. [Means for solving the problem]

[0012] A specific embodiment of the present invention will be described below with reference to the drawings. In this embodiment, a single-wire automatic circulating cableway will be described as a representative example of cableway facilities. FIG. 1 is a schematic diagram of a single-wire automatic circulating cableway. A single-wire automatic circulating cableway 10 has a station 11 and a station 12 at the end of the track, and each station 11, 12 is provided with a driving pulley 13 and a driven pulley 14 that can rotate freely. A cable 15 is endlessly wound around the driving pulley 13 and the driven pulley 14, and by driving the driving pulley 13 to rotate, the cable 15 moves in a circulating manner between the two stations 11, 12. A plurality of carriages 18 are suspended from the cable 15 at predetermined intervals along the track.

[0013] The carriage 18 is detachable from the cable 15, and is attached to the cable 15 on the track and moves together with the cable 15, and is detached from the cable 15 within the bus stops 11 and 12. The bus stops 11 and 12 are provided with U-shaped running rails 16 and 17 in plan view, and the carriage 18 detached from the cable 15 moves along the running rails 16 and 17 as follows. First, the carriage 18 that arrives at the bus stops 11 and 12 is detached from the cable 15 and transfers to the running rails 16 and 17, and is decelerated by a transfer device provided along the running rails 16 and 17. When the carriage 18 decelerates to a speed at which passengers can board and disembark, it turns around the bus stops 11 and 12 toward the departure side while maintaining that speed, and passengers board and disembark during this time. The carriage 18 which has turned back towards the departure side is accelerated to the same speed as that of the cable 15, and then attached to the cable 15 and detached from the running rails 16, 17 to depart onto the railway line.

[0014] Fig. 2 is a front view of the carriage 18, and Fig. 3 is a side view of the carriage 18. The carriage 18 is broadly composed of a gripping machine 19, a suspension machine 20, and a passenger car 21. The gripping machine 19 is configured to be able to grip and release the cable 15, gripping the cable 15 and moving together with the cable 15 on the track, and releasing the cable 15 within the stations 11 and 12, while the traveling rollers 22 roll on the traveling rails 16 and 17 to move. The gripping machine 19 is pivotally attached with a suspension machine 20 that can swing freely back and forth relative to the traveling direction, and a passenger car 21 carrying passengers is attached to the lower part of the suspension machine 20.

[0015] An air conditioner 24 is provided on the top surface 26 of the upper portion of the passenger car 21. The air conditioner 24 is an integrated type air conditioner 24 equipped with a compressor, an evaporator, a condenser, etc., and is driven by power supplied from a battery 25 provided under the passenger car 21, and supplies hot or cold air into the passenger car 21 from a vent provided in the upper portion of the passenger car 21. The battery 25 is a battery that can be rapidly charged, and is rapidly charged by receiving power from a current collector 23 provided on the carriage 18 when the carriage 18 moves through the stations 11 and 12.

[0016] 4 is a cross-sectional view showing the ventilation passage between air conditioner 24 and the interior of passenger car 21. Air intake 27 and air outlet 28 are provided at the bottom of air conditioner 24, protruding downward, and air taken in through air intake 27 is heated or cooled inside air conditioner 24 and discharged from air outlet 28. Meanwhile, ventilation openings 30, 31 are opened in roof 29 of passenger car 21 at positions corresponding to air intake 27 and air outlet 28.

[0017] A ceiling panel 32 is provided below the roof 29 of the passenger car 21 so as to cover the ceiling portion, and a space 33 is formed between the ceiling panel 32 and the roof 29. The air conditioning device 24 operates to draw air from the air inlet 27, and air inside the passenger car 21 is sent into the space 33. A converter 36 or an inverter 35 is supported inside the space 33 below the air inlet 27 and the ventilation openings 31, and the converter 36 or the inverter 35 converts the power of the battery 25 and supplies it to the air conditioning device 24.

[0018] With the above configuration, From the intake port (not shown) Sent to Space 33 Inside passenger car 21Air is drawn into the air conditioner 24 through the ventilation opening 31 and the air intake opening 27. At this time, the air comes into contact with the converter 36 or the inverter 35, absorbs the heat radiated from the converter 36 or the inverter 35, and is drawn into the air conditioner 24, thereby cooling the converter 36 or the inverter 35. The air is then heated or cooled in the air conditioner 24 and sent to the ventilation opening 28 side, and is sent into the passenger car 21 interior through the ventilation path 37.

[0019] As described above, according to the above configuration, the upper part of the passenger car 21 is covered with the ceiling panel 32 to form the space 33, and the converter 36 or the inverter 35 is installed in this space 33, making waterproofing measures unnecessary. In addition, by installing the converter 36 or the inverter 35 below the air intake 27 of the air conditioner 24, the air that has absorbed the heat dissipated by the converter 36 or the inverter 35 is drawn into the air conditioner 24, so that heat does not build up in the space 33 or the passenger car 21. Furthermore, since the ceiling panel 32 blocks the heat dissipation of the converter 36 or the inverter 35, the air conditioning in the passenger car 21 can be performed well. In addition, in the case of heating, the air warmed by the converter 36 or the inverter 35 is drawn into the air conditioner 24, improving the thermal efficiency of the air conditioner 24.
